Abstract:The effects of transverse electric field on the energy levels of electron and heavy hole, exciton binding energy and excitonic absorption spectra of GaAs parabolic quantum wire are theoretically investigated in detail. The results indicate that the electron and hole energy levels, exciton binding energy, excitonic absorption coefficient and absorption energy becomes smaller with the increase of electric field. That is more significant at the condition of weaker parabolic confinement potential. The phenomena can be explained by the separation of overlap integral of the electron and hole at the ground states. © 2011 Elsevier B.V. All rights reserved.

Abstract:This study was carried out to develop the application of modified carbon fiber electrode in environmental detection, by which chromium (III) ion in water could be electrochemically detected. The modified carbon fiber electrode manifested a linear response within the range of 1.9 × 10-6-4.6 × 10-4 mol L-1 (R = 0.9939) and the detection limit was 7.9 × 10-7 mol L-1. The effect factors were studied to reveal the optimal conditions in the detection of chromium (III) in water, such as pH of total ionic strength adjustment buffer, the concentration of calix[4]resorcinarene, sweep cycles, and so on. The modified carbon fiber electrode, the diameter of which was about 7 μm, was characterized by field emission scanning electron microscopy and electrochemical impedance spectroscopy. Also, the proper mechanism was discussed. The identification of chromium (III) was mainly attributed to the cavity of the calix[4]resorcinarene that the chromium (III) ion could enter into the inner of calix[4]resorcinarene because of the particular structure of calix[4]resorcinarene. © 2011 Published by Elsevier B.V.

Abstract:We analyze the magnetic properties through two-orbital Hubbard model with the spin-orbit coupling (SOC) interaction in the iron-based superconductors. With the help of the Ising approximation for the Hund's coupling between the itinerant electrons and the localized spins, we give a self-consistent account of the various magnetic orders observed in pnictides and the pairing symmetry. We also calculate the local density of states (LDOS) of the vortex state when a magnetic field is applied. The LDOS without SOC shows no resonant peak at the vortex core center in the superconducting state, while it shows an obvious resonant peak when SOC is applied. © 2011 Elsevier B.V.

Abstract:In this paper, we develop a theoretical framework about spatial patterns in a three-species predatorpreymutualist system with cross-diffusion. We concentrate on three aspects of Turing pattern formation: (1) what conditions enable the occurrence of Turing patterns? (2) what are the underlying mechanisms? (3) what are the corresponding configurations? For the first two questions, by use of the stability analysis for the positive uniform solution and the LeraySchauder degree theory, we prove that under some conditions, the system admits at least a nonhomogeneous stationary solution. For the third question, we carry out numerical simulations for a Turing pattern, and we show that the configurations of Turing pattern are stable spotted patterns, which resemble a real ecosystem. © 2011 Elsevier Ltd.

Abstract:This work presents an extension of the fluid approximation to the diffusion approximation for a PEPA model. The diffusion approximation leads to a reactiondiffusion system in which the spatial or location information is considered, while it is ignored in the fluid approximation approach. The fundamental results for the solution of the reactiondiffusion equations, such as the existence, uniqueness, positivity and convergence, have been established. Numerical simulations are also given to illustrate the analytical results. © 2011 Elsevier Ltd. All rights reserved.

Abstract:To improve transfection and expression efficiency of target gene, especially under cancer anoxic microenvironment, we have developed pHRE-Egr1-EGFP/PEI-MZF-NPs nanosystem, in which pHRE-Egr1-EGFP, eukaryotic gene expression plasmid, is constructed by combining radiation promoter Egr1 with anoxia induction components (HRE), forming anoxic radiation double sensitive HRE/Egr1 promoter to activate reporter gene EGFP expression. MZF-NPs (Mn 0.5 Zn0.5Fe2O4 magnetic nanoparticles), obtained by coprecipitation method, are coated with cation poly(ethylenimine) (PEI). We transferred pHRE-Egr1-EGFP into hepatocellular carcinoma Bel-7402 cells, using PEI-MZF-NPs as the carrier and tested some relevant efficacy. The results show that PEI-MZF-NPs have good DNA-binding ability, protection ability, release ability, little toxicity, and high transfection efficiency, obviously superior to those of the liposome method and electricity perforation method. Moreover, the expression level of EGFP gene induced by anoxia and radiation was significantly higher than that of single radiation activation. It is therefore concluded that HRE/Egr1 can induce and improve target gene expression efficiency in cancer anoxic microenvironment, and that PEI-MZF-NPs can be used as a novel nonviral gene vector which offers a viable approach to the mediated radiation gene therapy of cancer. © 2011 Mei Lin et al.

Abstract:Using U.S. NCEP / NCAR monthly mean reanalysis data (2.5×2.5) and daily precipitation data at 26 weather stations in Tarim River Basin from 1960 to 2009, spatiotemporal evolution characteristics of precipitation over Tarim River Basin (TRB) were analyzed. The results show that: 1) The spatial distribution of precipitation in TRB was in contrast with that in China, showing a gradual increase trend from southeast to northwest with some variation in different seasons and the year with more (less) rainfall; 2)The annual change in precipitation over mountains, plains and five sub-regions were likely consistent, and the decadal mutation of precipitation in around 1987 and 2003 appeared at almost all regions; 3)During the period of 1978 to 2003 in which global warming was the most significant, precipitation over mountain showed an clear increasing trend, while the precipitation over plain showed decreasing trend. It can be believed that the complexity of spatiotemporal distribution of precipitation over TRB implied a variety of precipitation mechanisms in this area, and the warm and wet evidence in western Tianshan Mountains may be the signal that global warming is accelerating the local water cycle. © 2011 IEEE.

Abstract:In order to certain the landscape pattern and ecological security in Zhangjiagang, the landscape characteristics of urbanization phase and suburbanization phase were analyzed, using remotely sensed imageries between 1991-2006, land use maps and GIS technology, combined with urban-suburban-rural gradient research. Based on the landscape changing and its driving force analysis, the regional Cultivated Land Instability Degree (CLID) of 2004 was defined and calculated. The ecological security of Zhangjiagang between 2003-2007 was also assessed to research the impacts of urbanization on urban ecological security. The urbanization process in Zhangjiagang matched the cyclic model and the diffusion wave theory and for casted the future land use/cover using CA Model. The effects of urbanization appeared in urban areas firstly, and then in rural areas. Two kinds of urban expansion patterns were detected in Zhangjiagang. The first one was from edge-expansion to infilling growth, the second one was from edge-expansion to spontaneous growth, and then to edge-expansion. Among all the agricultural ecological deficit, the largest proportion was the grassland ecological deficit, and agricultural ecological deficit increased by 16.22% from 2003 to 2007. This study had proved that the agricultural development was not sustainable in Zhangjiagang in recent years. © 2011 IEEE.

Abstract:In this paper, we analyze the performance of dither modulation (DM) against the composite attacks including valumetric scaling, additive noise and constant change. The analyses are developed under the assumptions that the host vector and noise vector are mutually independent and both of them have independently and identically distributed components. We derive the general expressions of the probability density functions of several concerned signals and the decoding error probability. The specific analytical results are presented for the case of generalized Gaussian host signal. Numerical simulations confirm the validity of the given theoretical analyses. © 2011 Springer-Verlag.

Abstract:In the last decade, the requirement for copyright protection of digital multimedia has become more and more urgent. As an efficient method to address this issue, watermarking has gained a lot of attention. To watermarking system, detectors have an important influence on its performance. In this paper, we propose a new optimal detector to multiplicative watermarking in the discrete cosine transform (DCT) domain, which is based on Cauchy models. Furthermore, theoretical analysis is also presented. The performance of the new detector is confirmed by various experiments. © 2011 Springer-Verlag.

Abstract:In order to further improve the accuracy and the mechanism of predicting winter wheat quality using remote sensing method, The quantitative relationships between remote sensing variables and agronomy parameters of winter wheat were analyzed. The results of the study showed that: the relationships between sedimentation value (SV) and remote sensing variables were more significant at booting stage than at jointing stage. At booting stage, SV presented a more significant correlation with SIPI than other remote sensing variables. An indirect model based on structure insensitive pigment index(SIPI) and leaf nitrogen content (LNC) and a direct model based on only optimization of soil-adjusted vegetation index(OSAVI) was established to predict SV. The indirect and direct models were evaluated with 20 samples by the determination coefficient(R2) with 0.741 and 0.555, the root mean square error(RMSE) with 3.64ml and 4.28ml, respectively. The indirect model performed better to predict SV with the higher accuracy by 15% than the direct model. It is concluded that the research can provide an effective way to improve the accuracy of predicting wheat quality with aerospace remote sensing, and contribute to large-scale application and promotion of the results. © 2011 IEEE.

Abstract:The free vibration experiments for the NOPD frame structure were performed to investigate the dynamic characteristics of the frame. The influences of factors such as particle filling ratio, particle filling scheme and vibration direction of the frame on the damping effect are discussed by means of test data. Test results indicate that the particle filling ratio is a principal influencing factor for the damping effect of the frame. Under the same particle filling scheme and filling ratio, the damping increments for out plane vibration of the frame with smaller structural rigidity are normally larger than those for in plane vibration with larger structural rigidity. Within the three schemes of particle filling, the most prominent damping improvement exists in the particle-in-beam scheme under the same filling ratio and the corresponding maximum damping increment reaches 218% for out plane vibration. To obtain the most significant particle damping effect, the most effective scheme of particle filling is to put particles into the cavities of components with large vibration displacement. © (2011) Trans Tech Publications.

Abstract:Raman spectra acquired from spherical, cubic, and cuboid SnO2 nanocrystals (NCs) reveal a morphologically independent Raman mode at ∼302cm-1. The frequency of this mode is slightly affected by the NC size, but the intensity increases obviously with decreasing NC size. By considering the dipole changes induced by oxygen vacancies and derivation based on the density functional theory and phonon confinement model, an oxygen vacancy density larger than 6% is shown to be responsible for the transformation of the IR to Raman active vibration mode, and the intensity enhancement is due to strong phonon confinement. © 2011 Optical Society of America.

Abstract:Chromosome segment duplications are integral in genome evolution by providing a source for the origin of new genes. In the rice genome, besides an ancient polyploidy event known in the rice common ancestor, it had been identified that there was a special segmental duplication involving chromosomes 11 and 12, but the biological role of this duplication remains unknown. In this study, by using a set of chromosome segment substitution lines (CSSLs) and near isogenic lines (NILs) derived from the indica cultivar 9311 and japonica cultivar Nipponbare, a major QTL (qS12) resulting in hybrid male sterility was mapped within ~400 kb region adjacent to the special duplicated segment on the short arm of chromosome 12. Compared to the japonica cultivar Nipponbare, the two sides of the qS12 candidate region were inverted in the indica cultivar 9311. Among 47 of the 111 rice genotypes evaluated by molecular markers, the inverted sides were detected, and found completely homologous to indica cultivar 9311. These results suggested that the two inverted sides protect the sequence in the qS12 regions from recombination. On the short-arm of chromosome 12, two QTLs S-e and S25, in addition to qS12, were previously detected as a distinct segregation distortion and pollen semi-sterility loci. We propose these three hybrid sterility loci are the same locus, and the duplicated segment on chromosome 12 may play a prominent role in diversification, i. e., sub-speciation of cultivated rice. © 2011 Springer-Verlag.

Abstract:Constant composition codes are codes where the frequency distribution of the elements in a codeword is the same for all codewords. In this paper, three classes of constant composition codes are constructed. These codes are subcodes of cyclic codes which have few weights occurring among the codewords. The new codes are excellent asymptotically compared to the previously best known constant composition codes. © 2011 IEEE.

Abstract:SnS2 nanocrystals with adjustable sizes were synthesized via a hydrothermal method from the aqueous solution of common and inexpensive SnCl4&bull5H2O, thioacetamide and citric acid, simply by varying the reaction temperature and reaction time. The structures, Brunauer-Emmett-Teller (BET) specific surface areas and optical properties of the resultant SnS2 nanocrystals were characterized by X-ray diffraction, transmission electron microscopy, N2 adsorption/desorption isotherms, and UV-vis diffuse reflectance spectra. Besides, their photocatalytic properties were tested for the reduction of aqueous Cr(VI) under visible light (λ > 420 nm) irradiation. It was found that the photocatalytic activities of SnS2 nanocrystals in aqueous suspension depended on their synthesis conditions. The product synthesized under suitable hydrothermal conditions (for example, at 150 °C for 12 h) not only showed high visible light-driven photocatalytic activity in the reduction of aqueous Cr(VI), but also showed good photocatalytic stability. Our photocatalytic results suggested that SnS2 nanocrystals are a promising photocatalyst in the efficient utilization of solar energy for the treatment of Cr(VI)-containing wastewater. © 2011 American Chemical Society.

Abstract:With increasing diversity and heterogeneity of content access devices and network technologies as well as user preferences, content delivery has evolved into a matter of ubiquitous service where production, delivery and access of content form major challenges for content provider, network operator and user respectively. Content adaptation has been widely acknowledged as one of the most important aspects for ubiquitous content delivery. Incorporating content adaptation into content delivery network has been intensively investigated in recent years, but still remains as a big challenge due to not only the technology heterogeneity and complexity, but also the deployment implication facing the different players in the content delivery chain, e.g. content provider, network operator, user, third-party service provider. This implication is caused by the lack of infrastructural support for content adaptation in traditional content delivery network. This paper presents the design of such an infrastructure, called Adaptation Management Framework (AMF). More importantly, this design targets its application in a distributed manner to allow content adaptation take place across the content delivery chain. A working cycle of content adaptation under the infrastructure is described, and performances evaluation and analysis are presented in terms of scalability. © 2011 IEEE.

Abstract:Mining frequent closed itemsets in data streams is an important task in stream data mining. In this paper, an efficient mining algorithm (denoted as EMAFCI) for frequent closed itemsets in data stream is proposed. The algorithm is based on the sliding window model, and uses a Bit Vector Table (denoted as BVTable) where the transactions and itemsets are recorded by the column and row vectors respectively. The algorithm first builds the BVTable for the first sliding window. Frequent closed itemsets can be detected by pair-test operations on the binary numbers in the table. After building the first BVTable, the algorithm updates the BVTable for each sliding window. The frequent closed itemsets in the sliding window can be identified from the BVTable. Algorithms are also proposed to modify BVTable when adding and deleting a transaction. The experimental results on synthetic and real data sets indicate that the proposed algorithm needs less CPU time and memory than other similar methods. © 2011 ACADEMY PUBLISHER.

Abstract:This paper deals with a diffusive logistic equation on one dimensional isotropically growing domain. The model equation on growing domains is first presented, and the comparison principle is then proved. The asymptotic behavior of temporal solutions to the reaction-diffusion problem is given by constructing upper and lower solutions. Our result shows that when the domain grows slowly, the species successfully spreads to the whole habitat and stabilizes at a positive steady state, while it dies out in the long run if the domain grows fast. Numerical simulations are also presented to illustrate the analytical result. © 2011 Springer Science+Business Media B.V.

Abstract:Electrode with optical shapes is appreciated in microfluidics. In this article, we reported a flexible poly(dimethylsiloxane) (PDMS)-based gold electrode for ascorbic acid detection. Gold nanoparticles were chemically deposited on PDMS and the composite film was applied as working electrode. The electrode could undergo deformation and display good response performance without damage. This biosensor could give quick response to ascorbic acid (AA) (<5. s) and the currents were linear with concentrations of AA in range of 0.023-7.00. mM and 30-100. mM, respectively. Limit of detection was 0.008. mM (S/N = 3). This biosensor has been applied to determine ascorbic acid content in vitamin C tablets and the results were consistent with traditional iodometric method. © 2011 Elsevier B.V.

Abstract:In order to facilitate the recovery of power, when the grid voltage drops in a certain range, the wind generator not only needs to protect the rotor side converter, but also should provide reactive power to the grid. This paper takes DFIG for an example. In order to protect the rotor side converter, it analyzes DFIG's electromagnetic transition process aroused by different voltage phase angle while the grid voltage drops. A control strategy to eliminate harmonic components during transition process is proposed. Simulation results show that the control strategy can not only achieve the purpose of protecting the rotor side converter, while eliminating the harmonic currents of stator side and rotor side when voltage drops, but also provide reactive power to the power grid.

Abstract:Tasks scheduling is a key problem in multi-agent system, traditional tasks scheduling methods can't be applied to new application areas of the MAS such as emergency system. In order to apply the Agent method to these new areas, a multi-agent system model is built in this paper, and corresponding task schedulable problem and maximum scheduling problem are defined based on this multi-agent system model. Task schedulable problem is modeled using flow network, and it is proved that maximum flow algorithm can be used to solve such problem, which means the problem can be solved in polynomial time. Furthermore, by analyzing the flow network model, a necessary and sufficient condition which can be used to determine whether tasks can be scheduled is gained and proved. Three approximation algorithms have been proposed to solve the maximum scheduling problem. The experiment results show that all above algorithms can get pretty solutions in solving maximum scheduling problem, and the approximation ratio for optimal solution of these approximation algorithms are all larger than or equal to 0.5 even though the resource ratio is very low. © 2011 ACADEMY PUBLISHER.

Abstract:Rice seed size is an important agronomic trait in determining the yield potential, and four seed size related genes (GS3, GW2, qSW5/GW5 and GIF1) have been cloned in rice so far. However, the relationship among these four genes is still unclear, which will impede the process of gene pyramiding breeding program to some extent. To shade light on the relationship of above four genes, gene expression analysis was performed with GS3-RNAi, GW2-RNAi lines and CSSL of qSW5 at the transcriptional level. The results clearly showed that qSW5 and GW2 positively regulate the expression of GS3. Meanwhile, qSW5 can be down-regulated by repression of GW2 transcription. Additionally, GIF1 expression was found to be positively regulated by qSW5 but negatively by GW2 and GS3. Moreover, the allelic effects of qSW5 and GS3 were detailedly characterized based on a natural population consisting of 180 rice cultivars. It was indicated that mutual interactions exist between the two genes, in which, qSW5 affecting seed length is masked by GS3 alleles, and GS3 affecting seed width is masked by qSW5 alleles. These findings provide more insights into the molecular mechanisms underlying seed size development in rice and are likely to be useful for improving rice grain yield. © 2011 Springer-Verlag.

Abstract:An electrochemical method has been successfully demonstrated for sensitive determination of azithromycin (Azi) with room temperature ionic liquid (IL) of 1-butyl-3-methylimidazolium hexafluorophosphate (BMIMPF6) - graphene (Gr) composite modified glassy carbon electrode (GCE). The cyclic voltammetric results indicate that Gr/IL/GCE can remarkably enhance electrocatalytic activity towards the oxidation of Azi in neutral solutions. Azi produce an anodic peak at about 0.82 V at this electrode. The electrocatalytic behavior was further exploited as a sensitive detection scheme for the Azi determination by differential-pulse voltammetry (DPV). Under optimized conditions, the concentration range and detection limit were 0.49-28.57 μg ml-1 and 0.19 μg ml-1 (S/N = 3) respectively for Azi. The method was successfully applied assay of the drug in the pharmaceutical dosage forms. © 2011 Elsevier B.V. All rights reserved.

Abstract:Porous anodic tin oxides were constructed via anodic oxidation of tin foils at room temperature. The optimal conditions for the porous anodic tin oxide growth has been explored based on the voltage-, oxalic acid concentration-, and time-dependent reactions. The formation mechanism of the porous anodic tin oxide film is also discussed. Raman spectra show an abnormal Raman peak at 693 cm-1 which is attributed to the IR-active A2uLO mode for the disorder of tin oxide with nanochannels.

Abstract:By the principles of mid-point primate polarization and center of gravity primate polarization, this paper put forth two triangle networks with fractal geometry nature, i.e. (1)mid-point polarization network and (2) centre of gravity polarization network. After introducing concept of dendrite dimension, the paper determined their dendrite dimensions, suggesting that the mid-point polarization network(MPN) hold both growth-triangle advantages and optimal fractal dimension for an ideal transport network. Upon this view, this article discussed the application of MPN with an example of core urban agglomeration of Henan province, whose ideal transport network planning being given as well. © 2011 IEEE.

Abstract:Ground thermal properties are important parameters for the design of ground heat exchangers (GHE) used in ground source heat pump (GSHP). In order to estimate the ground thermal properties of site, an experimental apparatus of in-situ thermal response test (TRT) was designed and built to measure the temperature response of ground, the experimental apparatus, test methodology and data analysis method were presented in detail. Based on the apparatus and data analysis model, a test project of GSHP located in the Hohhot of Inner Mongolia has been performed to determine the site ground thermal properties. The test results indicate that for the test borehole, the ground initial temperature is about 8.9∼9.2°C, the effective thermal conductivity and volumetric specific heat are 2.25W/(m·K) and 2045 kJ/(m3·K) respectively, and the borehole thermal resistance is about 0.133 (m·K)/W. At the same time, the voltage stabilizer and thermal insulation for exposed pipe should be used to improve test accuracy. The test data after 10 h should be selected to proceed for obtaining the results. The experimental validation shows that the thermal response experimental apparatus and analysis model proposed in this paper is feasible and can be used for the determination of ground thermal properties in the practical GSHP project. © 2011 IEEE.

Abstract:Preparation and sorption properties of spiro(fluorene-9,9′-xanthene)- based porous organic polymers (SPOPs) are reported for the first time. Using a same linker monomer, the micropore size and specific surface area in SPOPs are tunable by variation of the structure of core building blocks. According to the obtained nitrogen physisorption isotherms, the Brunauer-Emmett-Teller specific surface area for these polymers varies between 750 and 1020 m2 g -1. Copolymer SPOP-3 containing spiro(fluorene-9,9′-xanthene) and spirobifluorene with 1:1 ratio, prepared through Suzuki coupling polymerization, possesses 2.22 wt % hydrogen adsorption capacity at 1.0 bar and 77 K, which not only is the exceptional uptake capacity for hydrogen at low pressure among the best reported results for organic polymers but also can be competitive with other kinds of porous materials such as activated carbons and metal-organic frameworks. © 2011 American Chemical Society.

Abstract:Since the spot is elliptical when the cylindrical laser irradiates on the spatial plane, the pose of the spatial plane can be described by the elliptical spot. At the same time, the laser spot in the CCD plane is also elliptical. The information of the spatial plane will include in the image ellipse. The monocular vision has been established, and the boundary equation is obtained by image processing, and the relationship is derived between the boundary equation and the pose parameters of the spatial plane by minimum mean-square method. In order to obtain the depth information of the spatial plane, the boundary equation of the cylinder laser is introduced as the constrained condition. Because the constrained condition is transcendental equation set which includes trigonometric function, SWIFT (sequential weight increasing factor technique) is adopted for solving the parameters of the spatial plane. The simulation results show that the algorithm proposed is effective and feasible. © 2011 Springer-Verlag.

Abstract:Systems with simultaneous cooperation and competition among the elements are ubiquitous. In spite of their practical importance, knowledge on the evolution mechanism of this class of complex system is still very limited. In this work, by conducting extensive empirical survey to a large number of cooperationcompetition systems which cover wide categories and contain the information of network topology, cooperationcompetition gain, and the evolution time, we try to get some insights into the universal mechanism of their evolutions. Empirical investigations show that the distributions of cooperationcompetition gain interpolates between the power law function and the exponential function. Particularly, we found that the cooperationcompetition systems with longer evolution durations tend to have more heterogeneous distributions of cooperationcompetition gain. Such an empirical observation can be well explained by an analytic model in which the evolution of the systems are mainly controlled by the Matthew effect, and the marginal heterogeneity of the initial distribution is amplified by the Matthew effect with similar speed in spite of the diversity of the investigated systems. © 2011 Elsevier B.V.

Abstract:In this work, a kojic acid electrochemical sensor, based on a non-covalent molecularly imprinted polymer (MIP) modified electrode, had been fabricated in the lab-on-valve system. The sensitive layer was synthesized by cyclic voltammetry using o-phenylenediamine as the functional monomer and kojic acid as the template. The template molecules were then removed from the modified electrode surface by washing with NaOH solution. Differential pulse voltammetry method using ferricyanide as probe was applied as the analytical technique, after extraction of kojic acid on the electrode. Chemical and flow parameters associated with the extraction process were investigated. The response recorded with the imprinted sensor exhibited a response in a range of 0.01-0.2 μmol L-1 with a detection limit of 3 nmol L-1. The interference studies showed that the MIP modified electrode had excellent selectivity. Furthermore, the proposed MIP electrode exhibited good sensitivity and low sample/reagent consumption, and the sensor could be applied to the determination kojic acid in cosmetics samples. © 2011 Elsevier B.V.

Abstract:Digestibility of starches in four rice samples with amylose content (AC) from 1.7 to 55.4%, including a newly developed high-amylose rice, was investigated. An in vitro enzymatic starch digestion method and an AOAC method were applied to correlate rapidly digestible starch (RDS), slowly digestible starch (SDS), resistant starch (RS), and total dietary fiber (TDF) content with the AC in the samples. SDS content decreased and RS and TDF content increased with the increase in AC. The low-amylose rice (AC = 16.1%) had starch granules with weak crystalline structure and was lower in RS and TDF content even though it had a higher AC compared to waxy rice. The digestibility of the starches was not correlated with granule size or degree of crystallinity. The newly developed high-amylose rice starch exhibited a predominant B-type X-ray diffraction pattern, a great proportion of long chains in amylopectin, high gelatinization temperature, and semi-compound starch granules which are attributed to its increased resistance to enzyme digestion. © 2011 Elsevier Ltd.

Abstract:Solid superacid WO3/ZrO2 was prepared by co-precipitation of an aqueous zirconyl chloride and ammonium metatungstate solution. The as-prepared catalysts were characterized by using XRD, Laser Raman spectroscopy and BET. Acetyl salicylic acid was synthesized from salicylic acid and acetic anhydride using as-synthesized WO3/ZrO2. The effects of WO3 concentration, reaction time, reaction temperature, molar ratio of reactants, as well as dosage of catalysts on synthesis of acetyl salicylic acid were investigated, and the reaction conditions were therefore optimized. The excellent yield (91.0%) of acetylsalicylic acid was obtained under optimized reaction conditions. The catalyst has been easily recovered and reused repeatedly with a consistent high yield. © 2011 Elsevier B.V.

Abstract:Palladium nanoparticles modified glassy carbon electrodes (Pd/GC) were prepared via the electrodeposition of palladium on a glassy carbon (GC) electrode using cyclic voltammetry in different sweeping potential ranges. The scanning electron microscope images of palladium particles on the GC electrodes indicate that palladium particles with diameters of 20-50 nm were homogeneously dispersed on the GC electrode at the optimal deposition conditions, which can effectively catalyze the reduction of m-nitrophenol in aqueous solutions, but their catalytic activities are strongly related to the deposition conditions of Pd. The X-ray photoelectron spectroscopy spectra of the Pd/GC electrode confirmed that 37.1% Pd was contained in the surface composition of the Pd/GC electrode. The cyclic voltammograms of the Pd/GC electrode in the solution of m-nitrophenol show that the reduction peak of m-nitrophenol shifts towards the more positive potentials, accompanied with an increase in the peak current compared to the bare GC electrode. The electrocatalytic activity of the Pd/GC electrode is affected by pH values of the solution. In addition, the electrolysis of m-nitrophenol under a constant potential indicates that the reduction current of m-nitrophenol on the Pd/GC electrode is approximately 20 times larger than that on the bare GC electrode. © 2011 Elsevier Ltd.

Abstract:Few data are available about the effects of complexation of polyphenols with polysaccharide on their bioavailability. The complex of tea polyphenols (TP) with oat β-glucan was characterized by ultraviolet-visible spectrometry, Fourier transform infrared spectrometry, differential scanning calorimetry, atomic force microscopy, and solid-state 13C NMR spectroscopy. The results indicated that the bonds which governed the interaction between TP and oat β-glucan were strong hydrogen bonds. The in vitro antioxidant activity of TP, β-glucan, their complex, and physical mixture was assessed using four systems, namely, DPPH&bull, OH &bull, and O2&bull- scavenging activities and reducing power. The complexation and blending of TP and β-glucan exhibited different impacts on the index of in vitro and in vivo antioxidant capacities. In the concentration range of 0.5-2.5 mg mL-1, the complex had highest O2&bull- scavenging activity, whereas the highest OH&bull scavenging activity was found with the physical mixture. For antioxidant testing in vivo, there was no significant difference between the complex and the physical mixture in terms of glutathione peroxidase activity and levels of malondialdehyde and total antioxidant capacity in serums. However, the complex exhibited much higher activities of superoxide dismutase and glutathione peroxidase in livers than the physical mixture. The present study provided a deeper understanding of the influence of molecular interaction between TP and oat β-glucan on their antioxidant activities. © 2011 American Chemical Society.

Abstract:The application of curved surface is more and more popular in various kinds of engineering, for different curved surfaces ,because the form and formation way of their generatrix form are different, the surface properties are also different[1,2],so the relevant materials used must match with them too. As a designer, when he/she designs the curved surface, while in pursuit of the perfect modeling, he/she must take the scientific structure in consideration as well, so as to convenient for construction; As a constructor, he/she must fully understand the curved surface's character, rasp the mechanism, and then use a scientific and simple technique to achieve a perfect structure modeling. © (2011) Trans Tech Publications.

Abstract:A novel dopamine sensor was fabricated by forming the inclusion complex between mono-6-thio-β-cyclodextrin (CD-SH) and ferrocene (Fc) functionalized gold nanoparticles (GNPs) films on a platinum electrode. The properties of the GNPs/CDSH-Fc nanocomposite were characterized by Fourier transform infrared spectra, UV-visible absorption spectroscopy, transmission electron microscopy and cyclic voltammetry. The electrochemistry of dopamine (DA) was investigated by cyclic voltammetry (CV) and differential pulse voltammograms (DPV). The electrooxidation of dopamine could be catalyzed by Fc/Fc+ couple as a mediator and had a higher electrochemical response due to the unique performance of GNPs/CDSH-Fc. The anodic peaks of DA and ascorbic acid (AA) in their mixture can be well separated by the prepared electrode. Under optimum conditions linear calibration graphs were obtained over the DA concentration range 2.0 × 10- 6 to 5.0 × 10 - 5 M with a correlation coefficient of 0.998 and a detection limit of 9.0 × 10- 8 M (S/N = 3). The modified electrode had been effectively applied for the assay of DA in dopamine hydrochloride injections. This work provides a simple and easy approach to selectively detect DA in the presence of AA. © 2011 Elsevier B.V. All rights reserved.

Abstract:Three-dimensional incompressible Navier-Stokes equations closed by RNG κ-Ε turbulent model were adopted to simulate the internal flow of a sump shared by two cooling pumps. Computed results show that the bottom slop of the forbay and asymmetric operation scheme of pump sets will result in unfavorable flow conditions, and swirl angles of flow entering the suction pipe of pump are quantitatively analyzed. Since two pumps share a sump in a column, the auxiliary cooling pump in front will interfere with the flow fields of the sump, which is not favorable to the flow conditions of the main cooling pump. Three operation schemes with or without the auxiliary cooling pump were simulated to compare the influence of the flow fields of sump on the flow conditions of the main cooling pump, and the bias angles of flow entering the suction pipe are quantitatively calculated. The validity and reliability of numerical simulation are verified by a model test. The findings indicate that the computational fluid dynamics can be successfully applied to 3D flow of pump sump and numerical computation can provide reliable references for theoretical analyses, model test and modification of design scheme. © 2011 IEEE.

Abstract:Based on nonlinear prediction and NCEP/NCAR monthly multi-level geopotential heights, spatial heterogeneity of predictability was obtained over the Northern Hemisphere. On the whole, the predictability is high in continental and higher levels and low in oceans and lower levels from seasonal to interannual timescale. The predictability of the seasonal time scale is similar with the seasonal to interannual timescale. When it goes to the interannual time scale, the predictability becomes high in lower troposphere and low in mid-upper troposphere contrary to the formers. And on the whole the interannual trend is more predictable than the seasonal trend. The strength of the seasonal cycle plays a great role in the heterogeneity of predictability which is proved true by spectrum analysis. Other reasons maybe the properties of the atmospheric air, topographic forcing and timescale interactions. © 2011 IEEE.

Abstract:Porous magnetite (Fe3O4) nanospheres composed of primary nanocrystals have been successfully synthesized by solvothermal method with FeCl3·6H2O serving as the single iron resource, polyvinylpyrrolidone (PVP) as the capping agent, and sodium acetate as the precipitation agent. To understand the formation mechanism of the porous Fe3O4 nanospheres, the reaction conditions such as the concentration of the precursor, capping agent, precipitation agent, the reaction temperature, and reaction time were investigated. The characterization of the as-prepared product was identified with transmission electronic microscopy (TEM), field emission scanning electronic microscopy (FE-SEM), X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), vibrating sample magnetometer (VSM), N2 adsorption-desorption technique, and Fourier transform infrared spectroscopy (FTIR). The results indicate that the porous Fe3O4 nanospheres display excellent magnetic properties at room temperature, which allows them to be easily separated from the reaction system with the help of external magnet when they serve as catalysts. Catalytic activity studies show that the as-prepared porous Fe 3O4 nanospheres are highly effective catalysts for the degradation of xylenol orange (XO) in aqueous solution with H2O 2 as oxidant. The degradation reaction is first-order, its rate constant at room temperature being 0.056 min-1. Furthermore, the catalytic activity of Fe3O4 nanospheres decreases very slightly after seven cycles of the catalysis experiment. Therefore, porous Fe3O4 nanospheres can serve as effective recyclable catalysts for the degradation of XO. © 2011 American Chemical Society.

Abstract:Technological innovation capability includes two interrelated capabilities: technological development capabilities and technological transfer capabilities. At present technological development capacities of the majority of the regions in China are too weak to prevent sustainable regional development and technological capability. In this paper, a multivariate statistical analysis based on the Provincial Panel Data for 2003-2008 finds that regional (provincial) technological development abilities in China are obviously imbalance, and the abilities of Beijing, Shanghai and Guangdong are significantly advantage over other regions and the abilities of them derive from different environments and conditions, which provides a good example and enlightenment to the other parts of China. © 2011 IEEE.

Abstract:Because of large flexibility and strong geometric nonlinearrity, the time domain method should be applied in the analysis of wind-induced vibration for the membrane structure, and the coupling effect between the structure and the fluid should also be considered. In this problem, it is hard now to solve it directly using the technique of three-dimensional transient FSI based on CFD. So in the article, a compromise schedule is proposed, i.e, for the mean wind part, the steady-state FSI technique is applied to solve the parameter such as the mean pressure coefficient, the mean wind velocity, etc, while for the fluctuating wind part, the time integral method is used based on the stochastic function of the wind velocity formed by auto regressive method. The aerodynamic damping is considered in the solving of fluctuating part and five computing schedule are compared, result shows that it is better to use positive mean wind damping for the nodes. It is also suggested that the stochastic wind velocity functuion can be revised based on the kinetic energy distribution of the reference points. A comparison between the computing and testing results show that it is greatly improved for the fluctuating response distribution of the structure. © (2011) Trans Tech Publications, Switzerland.

Abstract:Parking facility capacity and city road network capacity are interrelated, and this results in problems such as parking disorder and transportation inefficacy if they are out of balance. So it is necessary to study the relationships between them in order to confirm the supply and distribution of parking facilities. This paper introduces the concept of road network capacity in the programming of parking facilities. The supply of curb parking facilities is the vinculum of parking supply capacity and road network capacity in the city. A model considering capacity configuration of parking facilities and networks is established to satisfy the expectation level of network service and balance the parking supply and network capacity. Finally, an example in (1∼4 park area) the city of TongLin in the Anhui province is demonstrated to prove the maneuverability of the method. © 2011 ASCE.

Abstract:To illustrate the working conditions of different intersections, the efficiency model was studied. Potential conflict intersection and actual conflict intersection were divided into two basic different types, whose efficiency models were developed both based on volume and speed. Comparison of efficiency between two types of intersections under different volume conditions shows: efficiency of actual conflict intersection was higher than that of the potential conflict intersection when the volume of the conflict traffic flows was low and lower when the volume of conflict traffic flows was relatively high. The conclusion indicates: efficiency index accords with the actual working condition and can be applied to the selection of different control modes. © 2011 ASCE.

Abstract:Pulse current (PC) electro-deposition combined with the ultrasonic (U) field has been used to fabricate pure nickel and nickel-ceria composite coatings. Morphology, ceria (RE) composite, and crystal-texture were observed and analyzed by using environment scanning electron microscopy equipped with energy dispersive X-ray analysis (ESEM/EDAX) and transmission electron microscopy (TEM). Experimental results indicate that it produced the alloying coatings, exhibiting compact grain and be of amorphous state. Nano-sized RE would preferentially occupy and pad the defective area between the cracked gap and micropores to limit the growth of the original Ni grain, and far from coarse grain. Furthermore, during annealed at 500 °C for 2 h, dispersing a solid-solution precipitated phase named NiCexO1-x (0<x<0.5), it would make diffused sufficiently to promote densification and microhardness greatly. © (2011) Trans Tech Publications.

Abstract:The loading paths are very important for hydroforming results in tube hydroforming, and need to be designed carefully. But the optimal loading paths are difficultly obtained by using empirical, analytical and experimental methods. FE simulation is perceived by the industry to be a cost-effective process analysis tool compared to the conventional hard tooling prototyping. Unfortunately, the prevalent trial-and-error based simulation method becomes very costly when the process analyzed is complex. More powerful design methods are needed to help the engineers design better THF loading paths, thus reducing lead times and costs. A new optimum design method for loading paths in THF, which integrates dynamic explicit FEM procedure into multiple-objective genetic algorithms based on elitist nodominated sorting genetic algorithm (NSGA-II), is brought forward in this paper. Using the method, a case study is carried out for the hydroforming of an instrument panel beam. The results show that the loading paths obtained by the method are better than the loading paths obtained by the trial and error. In addition, some results are obtained by running simulation program at a time, and which offers a wider choice for process parameters and designer's decision-making. © 2011 IEEE.

Abstract:When the cylindrical laser shines on the target object, a spot can be obtained, which the edge is a closed curve, marked as C1. The imaging of the curve C1 on the image surface of CCD is a closed curve C 2 too. Coordinate system is established to describe the position relationship among camera, image and light source, and to analyze the principle for monocular vision and laser ring to get the information about the object depth. In order to solve the problem and make the above principle clear, the key is to work out the expression for the curve C2 on the image surface of CCD. In order to calculate the closed curve C2 expression, the curve C2 will firstly be divided into two parts, the upper curve and the lower one. According to least-square polynomial, discrete points on the curves of two parts are drawn out, constraints are established and the curve equations are fitted. Then, to verify practicality of this method, a virtual model scene will be created, through which relevant data describing edge of virtual CCD image and that of a virtual spot when the virtual light source alights on the virtual object will be obtained. At last, closed curve equation will be fitted in accordance with data describing edge of virtual image; the position of space object will be fixed by making use of light source equation and closed curve equation; and a contrast will be made between the calculated value and data of the spot edge to prove whether a method to obtain the position of space objects based on monocular vision and laser ring is feasible. © (2011) Trans Tech Publications.

Abstract:Vector control method is the common way in traditional Double-fed Wind Generation, but it is more dependent on motor parameters, once the operational situation changes, the effect of the system control will be affected. This paper proposes a control method based on inverse system, through the inverse system theory, the state equation of doubly-fed induction motor (DFIG) and power converter, to construct the structure of the DFIG wind power generation inverse control system. Finally, the corresponding wind power generation closed-loop control system is established. When the system operates in variable speed constant frequency (VSCF) and the phase voltage drops, the simulation results show that the control system can keep the DC link voltage steady, maintain unity power factor, achieve the decoupling of the active and reactive power. It proves that this control method used in VSCF wind power generation is feasible. © 2011 IEEE.

Abstract:Aiming at the pivotal project is decorated jointly by sluice and pumping station, thus the relationship between each other is more complex. By using 3-D finite element software ABAQUS, the structure of pumping station was studied. Two methods were used when modeling and analyzing. For the method 1, only the model of pumping station was built and the check sluice was taken as a side load when calculating. For the method 2, the whole model of the joint hub of sluice and pumping station was built. The displacements and strength of the structure of pumping station can meet the requirements according to the calculated results. There is little difference between the calculated results of the two kinds of methods by comparison, but for the method 1, the calculations about displacements are all unsafe and it should be given enough attention, thereby the reliability and security of the design of similar projects will be guaranteed. © (2011) Trans Tech Publications.

Abstract:The purpose of this study is to further improve the accuracy of predicting winter wheat grain quality with remote sensing, and to enhance the prediction mechanism. In order to predict grain starch content (GSC) in winter wheat using HJ-1A/1B images, The experiment was carried out in Jiangsu regions during 2010 winter wheat growth season. Based on HJ-1A/1B image, synchronous or quasi-simultaneous ground observations of leaf nitrogen content(LNC) and grain quality parameters of winter wheat under different periods. Firstly, this study analyzed the relationships between GSC and LNC, and between LNC and satellite remote sensing variables. Secondly, based on remote sensing variable and LNC, the quantitative relationship models were established to predict GSC, and then evaluated with independent samples. Finally, the indirect model of predicting GSC based on remote sensing variable and LNC was compared to the direct model based on only structure insensitive pigment index(SIPI). The results showed that: at the booting stage, winter wheat GSC had a significantly positively correlation with Band(B1), Band4(B4), SIPI and plant senescence reflectance index(PSRI), and then it also had a significantly association with nitrogenous reflection index (NRI). At last, a direct model for predicting GSC was established with only SIPI. At the same time, LNC in this period also showed a higher correlation with GSC. Based on the high relationship between LNC and SIPI, an indirect model of predicting GSC also was established. The indirect and direct models were evaluated with independent samples by the determination coefficient(R2) with 0.662 and 0.533, the root mean square error(RMSE) with 5.72% and 6.34%, respectively. The indirect model based on SIPI and LNC performed better to predict wheat GSC than the direct model based on only SIPI, and obtained the higher accuracy by 9.7% than the direct model. It is concluded that the research can provide an effective way to improve the accuracy of predicting wheat quality based on aerospace remote sensing, and contribute to large-scale application and promotion of the research results. © 2011 IEEE.

Abstract:Owing to the deficiency of pinhole imaging model, a method to measure the depth information of the object based on lens imaging principle is proposed in this paper. By drawing on the two states of the measured object before and after changing position, this method manages to adjust the position of lens until the image become clearest, record the related information of position variation in order to obtain the depth information of the object. Meanwhile, whether the lens central plane is parallel to the CCD plane or not is also discussed, which is the reason why the image is fuzzy. A new kind of two degrees of freedom parallel adjusting mechanism was designed to solve the two problems above, which can achieve two degrees of freedom including independent moving and independent rotating. The clearest image can be obtained by adjusting the object distance and the image distance without changing the focal length of the camera. Besides, the mechanism can also be used to detect whether the installation position of lens central plane matches the CCD plane or not. © (2011) Trans Tech Publications.

Abstract:This paper is concerned with the spatial behavior of the interaction components of rotating N-component BoseEinstein condensates. The coexistence of minimal energy solutions is discussed and a mechanism to ensure coexistence is given. Moreover, if the condensation domain has a suitable shape, we prove that, as the interspecies interaction tends to infinity, the solution converges, along with suitable sequence, to a non-trivial spatially segregated state satisfying a non-coupled variational problem. © 2011 Elsevier Ltd.

Abstract:In this work we investigate the self-energy of elliptical dislocation loops in anisotropic crystals and determine the functional dependencies on loop circumference, shape, and dislocation core radius. Systematic numerical calculations using the anisotropic point force Green's function method are carried out with the goal of developing an analytical expression for the self-energy associated with these loops. The resulting formula is shown to accurately predict the self-energies for elliptical loops in anisotropic crystals, as well as the self-energies for simple loop configurations in isotropic crystals, for which analytical expressions exist. We apply this expression to predict the critical shell thickness corresponding to defect-free core/shell nanowires (NW) and further for the first time consider the effect of image energy due to the finite size of NW in anisotropic media using the boundary element method. Consequently, self-energy in NWs is corrected by an energy factor. Moreover, we discuss the dependence of the critical shell thickness on growth direction, with ⟨1 1 0⟩ NW having the largest, ⟨1 1 1⟩ NW the next largest, and ⟨1 1 2⟩ NW the finest. © 2011 Acta Materialia Inc.

Abstract:SnO2/SnS2 nanocomposite with a heterojunction structure (that is, SnO2 nanoparticles-decorated SnS2 nanoplates) was synthesized via the hydrothermal reaction between SnO 2 nanoparticles and thioacetamide in 5 vol.% acetic acid aqueous solution at 150 °C for 3 h, and characterized by X-ray diffraction, transmission electron microscopy, high-resolution transmission electron microscopy and UV-vis diffuse reflectance spectra. The photocatalytic activity of the hydrothermally synthesized SnO2/SnS2 nanocomposite was tested by degrading methyl orange in distilled water under visible light (λ > 420 nm) irradiation. It was found that the hydrothermally synthesized SnO2/SnS2 nanocomposite exhibited superior photocatalytic activity to SnO2 nanoparticles, SnS2 nanoplates and physically mixed SnO2/SnS2 nanocomposite. The heterojunction structure of the hydrothermally synthesized SnO 2/SnS2 nanocomposite, which can facilitate interfacial electron transfer and reduce the self-agglomeration of two components, was considered to play an important role in achieving its higher photocatalytic activity. © 2011 Elsevier B.V.

Abstract:The ground state and thermal entanglement of a two-qubit spin system in the presence of the nonlinear coupling interaction is investigated. It is found that the nonlinear coupling interaction can excite and enhance the entanglement both for ferromagnetic chain and anti-ferromagnetic ones even at the higher temperature. The entanglement teleportation via the quantum channel constructed by this system is also discussed, and the influence of the nonlinear coupling interaction on the fidelity of the teleportation is studied. The results show that both the entanglement of the output state and the fidelity can be increased by inducing a proper nonlinear coupling interaction. © 2011 Elsevier B.V. All rights reserved.

Abstract:According to the GB 50011-2001'Code for seismic design of buildings', 10 typical reinforced concrete (RC) frames were designed with different seismic fortification levels (from 6 to 8.5) and different fortification categories (B and C). The collapse resistances of the frames were evaluated quantitatively with collapse fragility analysis that was based on incremental dynamic analysis (IDA). The collapse resistances of frames with seismic fortification categories B and C were compared. The results show that the collapse resistances of structures should be evaluated in accordance with both the actual seismic resistance and the corresponding design intensity. For frames with seismic fortification level 6 to 7.5, since their actual aseismic resistances are relatively weak, their collapse resistances are insufficient when their seismic fortification categories are upgraded from B to C. So further measures are needed to enhance these structures.

Abstract:In this paper, we develop a theoretical framework for investigating spatial patterns on plankton allelopathy with cross-diffusion. We show that under some conditions the cross-diffusion is able to induce the Turing instability, which is further confirmed by the numerical simulations. Moreover, applying the LeraySchauder degree theory, we demonstrate that the cross-diffusion leads to an inhomogeneous stationary pattern provided with even stronger conditions. Finally, the wavenumber and the type of pattern selection are computed numerically. Our theoretical results of the spatial pattern are coincident with the experimental observations. © 2010 The Franklin Institute. Published by Elsevier Ltd. All rights reserved.

Abstract:In order to raise the reliability and convenience of calculating settlement, a practical method for calculating settlement based on actual stress path is proposed. According to stress path method, a practical expression for calculating settlement is put forward by using effective stress path equation derived from Skempton pore water pressure equation, which has the advantages of explicit conception and simple form with the parameters of expression easy to be obtained. An engineering case study shows that the proposed method is reliable; it can be taken as a reference for engineering applications.

Abstract:Composite gels were prepared from 2% myofibrillar protein (MP) with 10% imbedded pre-emulsified plant oils (olive and peanut) of various particle sizes at 0.6 M NaCl, pH 6.2. Dynamic rheological testing upon temperature sweeping (20-70 °C at 2 °C/min) showed substantial increases in G′ (elastic modulus) of MP sols/gels with the addition of emulsions, and the G′ increases were inversely related to the emulsion droplet size. Furthermore, gels containing emulsified olive oil had a greater (P < 0.05) hardness than those containing emulsified peanut oil. Regardless of oil types, MP-coated oil droplets exhibited stronger reinforcement of MP gels than Tween 80-stablized oil droplets; the latter composite gels had considerable syneresis. Light microscopy with paraffin sectioning revealed a stable gel structure when filled with protein-coated oil droplets, compared to gels with Tween 80-treated emulsions that showed coalesced oil droplets. These results suggest that rheological characteristics, hardness, texture, and water-holding capacity of MP gels were influenced by type of oils, the nature of the interfacial membrane, and the size of emulsion droplets. © 2011 Elsevier Ltd.

Abstract:Though computer technology has brought about virtual manufacturing to expedite design and analysis through simulation and visualization, machines remain essential, as ultimately products need to be made. There is a need for equipment providing more than three degrees of freedom (DOF) arranged in parallel and based on simpler arrangements than 6-DOF arrangements in application. This paper presents a new 4-DOF hybrid parallel platform manipulator with fixed-leg lengths and base mounted prismatic actuators. The movable platform of the manipulator can translate along two directions and rotate around two axes respectively (2T-2R). The kinematics model is formulated, which describes the inverse and forward kinematics transformation. It is very easy to develop a 5-axis NC machine-tool which is of large-workspace based on the 2T-2R, 4-DOF parallel mechanism presented in this paper. © 2011 Trans Tech Publications.

Abstract:The in situ electrochemical-ESR measurements of poly(aniline-co-o- aminophenol), PAoA, showed a strong dependence of the ESR signal intensity on the applied potential, revealed an unusual phenomenon that the ESR signal of PAoA can exist in a wide potential range from -0.20 to 1.30 V in aqueous solutions from pH <1 to 5.0, and gave a conversion potential of polaron to bipolaron, depending on pH and buffer capacity of the solutions. The ESR measurements also demonstrated that the ESR signal intensity of PAoA decreased with increasing pH, accompanied by increasing peak-to-peak line width; however, the g value of PAoA was hardly affected by pH and the applied potential. PAoA was first used to test the influence of antioxidants on its ESR spectra, which demonstrated that the ESR signal intensity of PAoA in the presence of dopamine and catechol was affected slightly; however, the ESR signal intensity of PAoA in the presence of ascorbic acid decreased pronouncedly compared to that of PAoA in its absence. Therefore, PAoA can be used as a probe of radical scavengers based on the ESR measurements, indicating that its applications can be extended to the biochemical field. © 2011 American Chemical Society.

Abstract:Though computer technology has brought about virtual manufacturing to expedite design and analysis through simulation and visualization, machines remain essential, as ultimately products need to be made. This paper presents a new type of 5-axis parallel machine tool based on a 3 degrees of freedom parallel platform manipulator with base mounted prismatic actuators. This machine tool is different from the Stewart platform type parallel machine tool in that its feed motion in X-direction is realized by the worktable on which work-piece is fixed and the parallel manipulator sliding on the gantry structure of the machine tool is responsible for the translation along Y-direction instead of the movable platform of the manipulator. Due to this special architecture, the workspace in X-direction and Y-direction of the new machine tool is enlarged greatly. and its rigidity is higher because of the adaptation of gantry structure. This machine tool is controlled by a PC based NC system in simultaneous 5 axes control mode. © (2011) Trans Tech Publications.

Abstract:Confirming the position in space of the camera axis and it perpendicular to the target surface has important significance for simplifying the camera calibration in interior parameters. This article conducted a study on this issue. First, it establishes the relationship of the world coordinate system, the target coordinate system, the camera coordinate system and the image coordinate system. The necessary camera calibration in external parameters and internal parameters are confirmed. Second, the first target coordinate system is adjusted to the same position with the world coordinate system. The adjustment principle of the camera axis perpendicular to the target column end surface is proposed. Namely, whether the camera axis perpendicular to the first target column end surface or not is confirmed by the CCD image edge whether it's round or not. As the world coordinate system is based on coordinate measuring machines, so the world coordinate of the first target column end surface circle is obtained. Then the second target is placed in between the camera and the first target, and the second target coordinate system is adjusted to the same position with the world coordinate system, and it is adjusted to the same coordinate (except y direction) with the first target column end surface circle's coordinates. So the images of the first target and the second target column end surface circle in the CCD surely are circles. Third, the method to seek for the camera axis is put forward, namely if the circles of the first target and the second target column end surface circle in the CCD are not concentric, then it shows the optical axis and the joined axis of the first and second target face round are not concentric. By adjusting the CCD camera's position, until the circles of the first target and the second target column end surface circle in the CCD are concentric, such the camera axis can be represented by the joined axis of the first and second target end round. Simultaneously the target circle's center reflects the deviation on CCD coordinate between the optical center and the CCD center. Finally, the camera internal parameters are expressed by the related parameters. © (2011) Trans Tech Publications.

Abstract:The problem of stabilization control is studied for a class of switched nonlinear systems in strict-feedback form in this paper. By introducing backstepping technique, and utilizing common control Lyapunov technique and Schur lemma, an improved switched control is developed. Compared with the existing literature, the proposed approach fully considers the virtual error term which is generated in backstepping design. The virtual error compensation term is adopted in controller. It is great convenient for stability analysis. By theoretical analysis, the closed-loop control system is shown to be globally uniformly asymptotically stable. Finally, simulation results are presented to illustrate the effectiveness of the proposed approach. © 2011 Chinese Assoc of Automation.

Abstract:Considering the weakness of Unsupervised Discriminant Projection (UDP), a novel feature extraction algorithm, termed Adaptive Supervised Discriminant Projection Analysis (ASDP), is proposed in the paper. The proposed algorithm does not only integrate a kind of dynamic feedback mechanism into construction of scatter matrices but also make full use of the class label information. The experimental results on AR and FERET face databases show the proposed method is more effective than some existing feature extraction methods such as UDP, LDA, etc. © 2011 Chinese Assoc of Automati.

Abstract:The adaptive control scheme combined with backstepping and fuzzy logic system is proposed for the output tracking control problem of a class of nonlinear systems with input delay. Fuzzy logic systems are employed to estimate the unknown continuous functions. The control scheme ensures that the closed-loop system is semi-globally uniformly ultimately bounded (SGUUB). The tracking error is proved to be bounded and ultimately converges to an adequately small compact set. The feasibility is investigated by a simulation example. © 2011 Chinese Assoc of Automati.

Abstract:The Lyapunov function of integral type is first introduced into a class of stochastic strict-feedback nonlinear systems with unknown virtual control gain functions. By utilizing the approximation capability of neural networks, backstepping technique and Young's inequality, a simple and effective adaptive neural network state feedback controller is constructed to ensure that the system is semi-global bounded in probability. Under some conditions, by the Lyapunov method, it is shown that all signals in the closed-loop system are bounded in probability. Simulation results are given to illustrate the effectiveness of the proposed control scheme. © 2011 Chinese Assoc of Automation.

Abstract:R0-algebras are the logic algebras associated to the formal deductive system L*for fuzzy propositional calculus. In this paper, the concepts of L-fuzzy subalgebras and L-fuzzy filters of R0-algebras are introduced. Properties of L-fuzzy subalgebras and L-fuzzy filters are investigated. characterizations of L-fuzzy subalgebras and L-fuzzy filters of R0-algebras are obtained. It is proved that an L-fuzzy set on an R0-algebra M is an L-fuzzy subalgebra of M if and only if for all t ∈ L, every its nonempty t-level section is a subalgebra of M. It is also proved that under some reasonable conditions, images and inverse images of L-fuzzy subalgebras (resp., L-fuzzy filters) of R0-algebra homomorphisms are still L-fuzzy subalgebras (resp. L-fuzzy filters). © 2011 Springer-Verlag Berlin Heidelberg.

Abstract:The need on finding sparse representations has attracted more and more people to research it. Researchers have developed many approaches (such as nonnegative constraint, l1-norm sparsity regularization and sparse Bayesian learning with independent Gaussian prior) for encouraging sparse solutions and established some conditions under which the feasible solutions could be found by those approaches. This paper commbined the L1-norm regularization and bayesian learning, called L1-norm sparse bayesian learning, which was inspired by RVM (relative vector machine). L1-norm sparse bayesian learning has found its applications in many fields such as MCR (multivariate curve resolution) and so on. We proposed a new method called BSMCR (bayesian sparse MCR) to enhance the quality of resolve result. © (2011) Trans Tech Publications.

Abstract:Rough set theory established by Pawlak in 1982 plays an important role in dealing with uncertain information and to some extent overlaps fuzzy set theory. The key notions of rough set theory are approximation spaces of pairs (U,R) with R being an equivalence relation on U and approximation operators R and R. Let R be the family {(RX, RX)|X ⊆ U} of approximations endowed with the pointwise order of set-inclusion. It is known that R is a complete Stone lattice with atoms and is isomorphic to the family of rough sets in the approximation space (U, R). This paper is devoted to investigate algebraicity and completely distributivity of R from the view of domain theory. To this end, completely compact elements, compact elements and atoms of R are represented. In terms of the representations established in this paper, it is proved that R is isomorphic to a complete ring of sets, consequently R is a completely distributive algebraic lattice. An example is given to show that R is not atomic nor Boolean in general. Further, a sufficient and necessary condition for R being atomic is thus given. © 2011 Springer-Verlag Berlin Heidelberg.

Abstract:The purpose of this study is to further improve the accuracy of predicting winter wheat quality with remote sensing, and to enhance the prediction mechanism. In order to predict wet gluten content (WGC) in winter wheat using HJ-1A/1B images, The experiment was carried out in Jiangsu regions during 2010 winter wheat growth season. Based on HJ-1A/1B image, synchronous or quasi-simultaneous ground observations of SPAD value, biomass, leaf area index(LAI), leaf nitrogen content(LNC) and grain quality parameters of winter wheat at jointing and booting stage. Firstly, this study analyzed the relationships between WGC and remote sensing variables, and between growth parameters and satellite remote sensing variables. Secondly, the quantitative models were established and evaluated to predict WGC. Finally, the indirect model of predicting WGC based on remote sensing variable and biomass was compared to the direct model based on only remote sensing variable. The results showed that: The relationship between WGC and remote sensing variables was more significant at booting stage than at jointing stage. At booting stage, WGC presented a more significant correlation with normalized difference vegetation index(NDVI) than other remote sensing variables. At last, a direct model for predicting WGC was established with only NDVI. At the same time, biomass in this period also showed a higher correlation with WGC. Based on NDVI and biomass, an indirect model of predicting WGC also was established. The indirect and direct models were evaluated with 25 independent samples by the determination coefficient(R2) with 0.766 and 0.674, the root mean square error(RMSE) with 1.81% and 2.59%, respectively. The indirect model based on NDVI and biomass performed better to predict winter wheat WGC than the direct model based on only NDVI, and obtained the higher accuracy by 30% than the direct model. It is concluded that the research can provide an effective way to improve the accuracy of predicting wheat quality based on aerospace remote sensing, and contribute to large-scale application and promotion of the research results. © 2011 IEEE.

Abstract:Governments have an irreplaceable role in technical progress, but they can not be the main body instead of business. Goals of governments and enterprises in technological innovation are not consistent, so governments should build a "field" for enhancing businesses the sense of competitive edge and innovative preferences to motivate and guide technological innovation. The optimal behavior of the government should: firstly, improve the market mechanism, secondly, explore the laws on technological innovation and enhance their coordinative ability of resources, and finally conduct a survey to understand the practical needs of enterprises in technological innovation so as to give different guidance to different categories of enterprises. Optimal behavior should be measured by the probability of success, profitability and sustanability of technological innovation of enterprises. © 2011 IEEE.

Abstract:Using the sample of 257 China□s listed companies 3341 observations between 1996 and 2008, this paper studies the trade receivables action of financial distressed companies. We find a negative effect of financial distress on trade receivables, which implies that firms reduce their trade receivables when they are in financial distress. We also find that distressed companies in East China, South China and Northeast reduce their trade receivables; distressed companies in Northwest increase their trade receivables; and there are no significant relationship between trade receivables and financial distress for those distressed companies in North China, Central China and Southwest. © 2011 IEEE.

Abstract:Tetraphenylethylene-based porous organic polymers were synthesized efficiently through a Suzuki coupling polycondensation or oxidative coupling polymerization. According to the obtained nitrogen physisorption isotherms, the Brunauer-Emmett-Teller specific surface area values for these porous materials vary between 472 and 810 m2 g-1. Using the same linker monomer, the specific surface area of copolymer materials (TPOP-3 or TPOP-5) prepared by two different core structural monomers (tetraphenylethylene and spirobifluorene) is higher than those of the respective homopolymers. Gravimetric hydrogen adsorption isotherms show that the adsorption capacity for hydrogen is up to 1.07 wt% at 1.13 bar and 77 K. Furthermore, incorporation of tetraphenylethylene moieties into these polymers can induce high photoluminescence (λmax: 530-610 nm) in the solid state. Thanks to the propeller-like structure and aggregation-induced emission characteristics, tetraphenylethylene is to be a promising building block for designing porous polymers with special properties. © 2011 The Royal Society of Chemistry.

Abstract:Although major factors affecting the membrane bioreactor fouling process have been identified, no linear relationships between these factors and fouling were established. This indicates the existence of synergistic interplays among these factors in determining the overall fouling behavior. The synergistic effect on fouling hasn't been fully considered in the fouling mathematical model development. Activated sludge within membrane bioreactor is a complex mixture of soluble, colloidal and solid materials. In this paper, a theoretical model was developed to account for the synergistic effects of soluble, colloidal and suspended activated sludge components on the fouling process. It included the major advances in the fouling mechanisms based on the pore constriction, pore blockage and cake filtration. The model prediction was shown to be in excellent agreement with experimental results from literature. This suggests that modeling approach in this paper is valid in predicting the flux decline process. © 2011 Elsevier B.V.

Abstract:Electronic structures and magnetoresistance (MR) of pseudo-spin-valves structure (PSV) Co3/Cu3/Ni3/Cu3(1 0 0), Co3/Cu3/Ni3/Cu3(1 1 0), and Co3/Cu3/Ni3/Cu3(1 1 1) are studied using the full potential linearized augmented plane wave (FLAPW) method with generalized-gradient approximation (GGA) for the exchange correlation interactions. It has been found that the spin-dependence scatterings at interfaces are insignificant compared with the ones of the interior layers for the three orientation superlattices. Also, we evaluate the MR ratio by means of the two-current model, and find that the MR ratio of Co3/Cu 3/Ni3/Cu3(1 0 0) (73.72%) is larger than those of structures Co3/Cu3/Ni3/Cu3(1 1 0) (68.38%), and Co3/Cu3/Ni3/Cu3(1 1 1) (67.09%). © 2011 Elsevier B.V.

Abstract:A topology of coupled inductor double boost inverter (CIDBI) is proposed based on the photovoltaic micro-inverter module system. The operation principle and control strategy of CIDBI are analyzed in detail and the gain expression from DC side to AC side is deduced. It can generate an AC output voltage much larger than the DC input one, depending on the proper setup of instantaneous duty cycle and turn ratio of the coupled inductors. Firstly, based on a given driving signal series, the operational principle of CIDBI is discussed. Secondly, the voltage stress of switches in CIDBI and the relationship between input and output are analyzed. The gain is approximately proportional to the duty cycle when the duty cycle is around 0.5 and the sinusoidal pulse width modulation (SPWM) is applicable to this novel inverter. Finally, the proposed CIDBI serves as a grid-connected inverter in a photovoltaic generation system. Experimental results show that the CIDBI can competently implement the single-stage grid-connected generation of photovoltaic system with a low level total harmonic distortion of current and high efficiency, without traditional transformer and DC/DC converter. © 2011 State Grid Electric Power Research Institute Press.

Abstract:In this article, a secure and verifiable vector space secret sharing scheme without a dealer is proposed in detail. It's security is based on the security of elliptic curve cryptography. This scheme has the following characteristics: There is no dealer, thus the cost can be saved and it makes the scheme more security. A verifiable infrastructure based on elliptic curve cryptography is provided, which can be used to detect the cheaters from participants and outside attackers. Meanwhile, the length of key of elliptic curve cryptography is much less than that of RSA cryptography, so the current scheme is valuable in applications with limited memory and communication bandwidth. Results indicate that the security and information rate of this scheme is very high. Analysis shows that this scheme is perfect. © 2011 IEEE.

Under the experimental conditions, with NH4+ concentration increased, the efficiency of nitrogen transformation is decreased in this SBR system, meantime the N2O-N ratio is rapidly increase. Using PCR-DGGE technique analysis characteristics of microbial communities in SBR system under the different concentrations of NH4+ Showed that in high NH4+ concentration(60 mg · L-1) the microbial community is quite different when compared to medium (40 mg · L-1) and low(20 mg · L-1) concentrations. N 2O emission in high NH4+ concentration was effected by the nitrogen conversion efficiency and the changes in microbial community. In this study, the proportion of N2O-N is 0.25%∼6.35% in the wastewater nitrogen removal process under different NH4 + concentrations. © 2011 IEEE.

Abstract:The purpose of this study is to further improve the accuracy of predicting winter wheat grain quality with remote sensing, to enhance the prediction mechanism and to meet the demand for winter wheat production. In order to predict grain protein content (GPC) in winter wheat using landsat TM images, The experiment was carried out in Jiangsu regions during 2007-2009 winter wheat growth season. Based on Landsat TM image, synchronous or quasi-simultaneous ground observations of leaf nitrogen content(LNC) and grain quality indices of winter wheat under different years and different periods. Firstly, this study analysised the relationships between GPC and LNC, and between LNC and satellite remote sensing variables. Secondly, based on remote sensing variable and LNC, the quantitative relationship models were established to predict GPC of winter wheat, and then evaluated with independent samples. Finally, the indirect model of predicting GPC based on remote sensing variable and LNC was compared to the direct moedel based on only NDVI. The results showed that: anthesis stage can be considered as the sensitive period to predict grain protein content, and it was sensitive to predict GPC of winter wheat using NDVI. the indirect and direct moedels were evaluated with independent samples by the determination coefficient(R2) with 0.412 and 0.379, the root mean square error(RMSE) with 0.367% and 0.418%, respectively. The indirect model based on NDVI and LNC performed better to predict wheat GPC than the direct model based on only NDVI, and obtained the higher accuracy by 8.5% than the direct model. The result of appling the indirect model was correspondent with the actual distribution of wheat GPC. It is concluded that the reseach can provide an effective way to improve the accuracy of predicting wheat quality based on aerospace remote sensing, and contribute to large-scale application and promotion of the research results. © 2011 IEEE.

Abstract:In order to solve the problem of nitrogen over-use in high yield direct seeding rice after cultivating wheat, the research explored different nitro-saving cultivation method from 2008 to 2009, by increasing the rice planting density to enhance yield on wheat stubble. This study set up a test of different direct seeding density in 2 years continuously with 150 kg nitrogen application dose per hectare (as much as 50%-60% nitrogen application dose in regular high yield cultivation condition). By analyzing the productivity, constituent factors, index of quality, RVA of rice, dynamics of leave and tilling, dry matter accumulation etc, the results showed that in conditions of 300 million basic seedlings per hectare, the yield was similar to the conventional nitro-use cultivation. This solution not only relieved the pressure of fertilize on environmental pollution by saving 100-120kg nitrogen per hectare, but also the improved benefits exceed the prime cost of increased use of seeds. This breakthrough innovation provided an alternative for the research of high quality direct seeding rice. © 2011 IEEE.

Abstract:River networks (including rivers and drainages) ecosystems in many irrigation districts are getting worse as the development of farmland irrigation. Ecosystem service values can reflect the deteriorating situation of river networks ecosystems. In this paper, a classification of river network ecosystem service values of irrigation district is presented and suitable estimate methods are recommended. According to the basic data of Yanyun Irrigation District in Jiangsu Province from year 2003 to 2007, the assessment of ecosystem services value have been completed on market prices method, replacement cost method and opportunity cost method. The result shows that the annual average service value is 136,313,600 Yuan RMB, and the annual average service value per hectare is 4,150 Yuan RMB. Because of agricultural non-point sources pollution, the service value of water supply is quite small, and only accounts for 2.2% of the total. The service value of aquatic products supply is also decreases gradually. © 2011 IEEE.

Abstract:Study on Spatial distribution of negative aero-anion concentration in the waterfall environment of ShiBiLiuzong. Results showed that the negative aero-anion concentration was decreased with the increase of the distance from the water fall center and the decreased degree tended to mitigation with the increase of the distance from the waterfall center. There was very significant difference among the negative aero-anion concentration in different areas from the waterfall center. The azimuth of observation had some influence on the negative aero-anion concentration. Within the test range, the negative aero-anion concentration reached the highest in the south, took second in the southeast and reached the lowest in the southwest. © 2011 IEEE.

Abstract:A simple hydrothermal method was developed for the size-controlled synthesis of SnS2 nanoparticles, using common and inexpensive SnCl4·5H2O and thioacetamide as the reactants and 5 vol.% acetic acid aqueous solution as the solvent. The structure, composition and optical property of the obtained products were characterized by X-ray diffraction, transmission electron microscopy, energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, Brumauer-Emmett-Teller (BET) surface area analysis and UV-vis diffuse reflectance spectra, and their possible formation mechanism was proposed. Besides, their photocatalytic properties were tested by degrading methyl orange in distilled water (20 mg/l) under visible light (λ > 420 nm) irradiation. It was found that SnS2 nanoparticles synthesized under the appropriate hydrothermal conditions not only exhibited high visible light-driven photocatalytic activity, but also had good photocatalytic stability. © 2011 Elsevier B.V.

Abstract:In this study, various polypropylene (PP) nanocomposites were prepared by melt blending method. The effects of different spherical nanofillers, such as 50 nm CaCO3 and 20 nm SiO2, on the linear viscoelastic property, crystallization behavior, morphology and mechanical property of the resulting PP nanocomposites were examined. Rheological study indicated that coincorporation of nano-SiO2 and nano-CaCO3 favored the uniform dispersion of nanoparticles in the PP matrix. Differential scanning calorimeter (DSC) and polarizing optical microscopy (POM) studies revealed that the coincorporation of SiO2 and CaCO3 nanoparticles could effectively improve PP crystallizability, which gave rise to a lower supercooling temperature (ΔT), a shorter crystallization half-life (t 1/2) and a smaller spherulite size in comparison with those nanocomposites incorporating only one type of CaCO3 or SiO 2 nanoparticles. The mechanical analysis results also showed that addition of two types of nanoparticles into PP matrix gave rise to enhanced performance than the nanocomposites containing CaCO3 or SiO 2 individually. © 2011 Wiley Periodicals, Inc.

Abstract:Tetraphenylethylene (TPE)-based glycoconjugates were easily synthesized by copper(I)-catalyzed "click reactions" between propargyl-attached TPE and azido-functionalized sugars. The TPE compound bearing lactosyl moieties (Lac-TPE) was found to be a fluorescence "turn-on" sensor for cholera toxin by virtue of aggregation-induced emission characteristics of the TPE motif owing to the specific interaction of lactose with the cholera toxin B subunit, whilst a cellobiose-functionalized TPE derivative did not show any response to the toxin. Therefore, Lac-TPE shows promising applications in the detection of cholera toxin, as well as in the investigation of carbohydrate-protein interaction. Copyright © 2011 Wiley-VCH Verlag GmbH & Co.

Abstract:Multi-DOF spherical initiative joint droved by spherical motor directly. It has high mechanical integration and advantage in the control and trajectory planning. But when the joint works, the friction and wear due to mechanical support, resulting in joint components fever, leading to joint static and dynamic performance deteriorated. Based on the motor technology, magnetic levitation technology and robot technology, presents a no mechanical friction and wear, no lubrication reluctance many degrees of freedom magnetic suspension ball joint initiative structure. Its working principle is that according to the air gap magnetic of active joint, derivate rotation angle displacement and radial displacement of the spherical rotor and calculated the total levitation force and electromagnetic torque model in a joint derivation coordinates. Based on the levitation force and torque model, it established active joint system dynamics model and inverse model.

Abstract:Influence of the pulse currents, the pulse frequency and CoSO4 content of plating solution on Co content of Ni-Co alloy coatings are investigated by environmental scanning electronic microscopy and field emission scanning electronic microscope. The result shows that Co content of Ni-Co alloy coating increases as the increase of CoSO4 content and pulse frequency. Co content of Ni-Co alloy coating increases when the current density decrease. When CoSO4 content of plating solution and the pulse frequency increase, the coating surface become smoother, microstructure become denser and coating grain refinement. when current density is small, coating crystalline grains size are tiny and the coating crystalline grains arrangement is relatively close. In the Ni-Co electrodepositing process, the combining of Ni2+ and Co2+ generates [CoNi (II)] intermediate products, then the decomposion of [CoNi (II)] generate Co and Ni2+. This hinders sedimentation of Ni2+ ions and increases sedimentary speed of Co2+ ion. Polarization of electrodeposited cobalt is lager than polarization of electrodeposited nickel. So as the current density increases, nickel deposition relative faster than cobalt, thus leads to the cobalt content of coating decreased. The recovering frequency of metal ion concentration in pulse spread layer rise at the fixed time as pulse frequency increases. © (2011) Trans Tech Publications.

Abstract:By using the method of density-matrix renormalization group, the reduced fidelity and entanglement in the one-dimensional bond-alternating S = 1 Heisenberg chain are investigated. The results demonstrate that the quantum phase transition from the Haldane phase to the dimer phase can be characterized by the reduced fidelity and the first derivation of the entanglement entropy. Through the finite-size scaling, the critical point and the critical exponent of the correlation length are obtained accurately. © 2011 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.

Abstract:According to the theory of electron tunneling barrier in quantum well structure, the photoelectric properties for GaN-based blue light emitting diodes (LEDs) with different heights, widths of the barrier and quantum well have been simulated by the APSYS software. The calculations of the I-V characteristics, light intensity, internal quantum efficiency at different conditions show that there is a red-shift in the spontaneous emission spectrum. Compared with the conventional quantum well parameters of LED, the optimized LED structures have better photoelectric properties with a voltage reduction of 18.43%, light intensity enhancement of 11.46% and red-shift reduction of 5 nm at a well width of 2 nm, barrier width of 4 nm, In component of 0.08 in barriers, and drive current of 20 mA.

Abstract:Rough set theory is a powerful mathematical tool for dealing with inexact, uncertain or vague information. The core concepts of rough set theory are information systems and approximation operators of approximation spaces. Approximation operators draw close links between rough set theory and topology. This paper concerns generalized approximation spaces via topological methods and studies topological properties of rough sets. Classical separation axioms, compactness and connectedness for topological spaces are extended to generalized approximation spaces. Relationships among separation axioms for generalized approximation spaces and relationships between topological spaces and their induced generalized approximation spaces are investigated. An example is given to illustrate a new approach to recover missing values for incomplete information systems by regularity of generalized approximation spaces. © 2011 Elsevier Inc.

Abstract:Acidic ionic liquid N-carboxymethylpyridine hydrosulphate ([CH2COOHPy]HSO4) as the extractant and catalyst, and hydrogen peroxide as the oxidant were used to the extraction-oxidation desulphurization of model oil (dibenzothiophene dissolved in n-octane). The effects of the amounts of hydrogen peroxide and ionic liquid, reaction temperature and reaction time on the sulfur removal were investigated. The results show that when molar ratio of sulfur to H2O2 is 1:6, volume ratio of ionic liquid to model oil is 0.6:10, and reaction time is 40 min at 50°C, the sulfur removal of model oil can reach 99.7%. The ionic liquid can be recycled 5 times without obvious decrease in the sulfur removal.

Abstract:Based on the first-order shear deformation theory (FSDT), linear transformation relationship between bending solutions of functionally graded material (FGM) and homogenous circular plates was studied. Firstly, through theoretically analyzing and comparing the displacement-type governing equations for axially symmetrically bending of FGM and homogenous circular plates based on the first-order shear deformation theory, linearly dependent relationship between the rotational angles of FGM circular plate and those of homogenous one was found. By giving the material properties of FGM circular plates changing as continuous functions in the thickness direction, the corresponding transition factor between the solutions of the two kind plates were derived in analytical forms. Furthermore, a linear relationship between the deflections of FGM circular plate based on FSDT and those of homogenous one based on the classical plate theory were derived. As a result, solutions for static bending based on the first-order shear deformation plate theory of a non-homogenous circular plate can be reduced to that based on classical plate theory of a homogenous one and the calculation of the transformation factors. This approach provides a simple and facile procedure for solutions of the non-homogenous moderately thick FGM circular plates, which can be very easily and conveniently used in engineering. By using the above mentioned approach, analytical bending solutions of FGM circular plates with simply supported as well as clamped boundary conditions under uniformly distributed lateral force were presented, which show a very good agreement with the results given by Reddy.

Abstract:Using earthworms for the treatment of organic solid wastes has more advantages than conventional techniques and aroused extensive attention. In this study, cow manure was treated by earthworm bio-bed, and then changes of physicochemical and biological properties of cow manure before and after the treatment were investigated based on laboratory measurements. The results showed that cow manure after the earthworm bio-bed treatment had advantages of better water and air penetrating properties, easy drying and no order. Both water content and electrical conductivity in cow manure significantly decreased, and pH tended to be neutral. The earthworm bio-bed treatment reduced total nitrogen and organic matter content but elevated ammonium and nitrate content in the manure. Total potassium and total phosphorus, including the fractions of organic phosphorus, inorganic phosphorus and available phosphorus in treated manure increased while available potassium decreased. Humic acid content had no significant changes. The removal efficiency of Cr, Cd and Cu by the treatment was better than that of Pb, Mn, Zn and Fe. The treatment process enriched microbial flora, increased catalase activity and reduced urease activity in vermicompost. In addition, the carbohydrates in the cow manure gradually decomposed and changed to humic substances, while water-soluble organic silicon compounds were converted into inorganic silicon oxides during the earthworm bio-bed treatment.

Abstract:A modified Green-Ampt model (MGAM) was proposed in this study to simulate water infiltration in layered soils with entrapped air. A saturation coefficient Sa (less than 1) was introduced in MGAM to account for the effect of air entrapment on infiltration. The Sa could be approximately determined from soil physical properties. Infiltration experiments in a laboratory layered soil column and field layered soil profile were conducted to test the applicability of MGAM. For comparison, the infiltration process was also simulated by the traditional Green-Ampt model (TGAM) and the Bouwer Green-Ampt model (BGAM). The estimated Sa values by these model were very close to the measured saturation degree of soil layers at the termination of experiment. The simulation results indicate that the TGAM significantly overestimated the infiltration rate and cumulative infiltration, whereas the BGAM considerably underestimated the infiltration rate and cumulative infiltration. Furthermore, the depths of wetting front simulated by TGAM and BGAM were considerably smaller than the measured values. The comparison result shows that, the MGAM provided satisfactory simulation results, and it adequately described the infiltration process in both the laboratory soil column and field soil profile.

Abstract:Laccase was immobilized on M-NH2-SiO2 with glutaraldehyde as crosslinking agent. The effects on the activity of immobilized laccase, such as concentration of 2, 4-DCP (2, 4-dichlorophenols), acidity of solution, temperature were studied. The results show when concentration of 2, 4-DCP is 5 mg·L-1, pH of solution is 5.5, and the temperature is at 30°C, the highest removal rate of 2, 4-DCP is 42.28%. The results show that the optimal pH for immobilized laccase is higher than the best pH for free enzyme. Compared with the free enzyme, its stability and repetition are considerably improved.

Abstract:According to the Code for Seismic Design of Buildings (GB50011-2001), ten typical reinforced concrete (RC) frame structures, used as school classroom buildings, are designed with different seismic fortification intensities (SFIs) (SFI=6 to 8. 5) and different seismic design categories (SDCs) (SDC=B and C). The collapse resistance of the frames with SDC=B and C in terms of collapse fragility curves are quantitatively evaluated and compared via incremental dynamic analysis (IDA). The results show that the collapse resistance of structures should be evaluated based on both the absolute seismic resistance and the corresponding design seismic intensity. For the frames with SFI from 6 to 7. 5, because they have relatively low absolute seismic resistance, their collapse resistance is insufficient even when their corresponding SDCs are upgraded from B to C. Thus, further measures are needed to enhance these structures, and some suggestions are proposed. © 2011 Institute of Engineering Mechanics, China Earthquake Administration and Springer-Verlag Berlin Heidelberg.

Abstract:According to the forming process of cold-extruded internal thread of high-strength steel, the effect of parts status on the fatigue properties of internal thread was studied from the microscopic viewpoint, such as residual stress, surface roughness, microhardness, hardened layer, etc. The results showed that the metal surface of cold-extruded internal thread had a long fibrous structure, and it appeared to be streamline type and distributed along the normal direction of the tooth surface. The grains were pressed and refined, and the dislocation density was increased significantly. The work hardening phenomenon was appeared, and made the strength and the hardness of the metal increase. The residual compressive stress field formed on the surface of the metal could eliminate the impact of stress concentration, reducing fatigue notch sensitive, extending period of crack forming and slowing or restraining the expanding of the crack. The surface of cold-extruded internal thread had obvious finish mark, and its smooth of the surface was well. The surface roughness could be eliminated effectively, and reducing stress concentration and contributing to increasing the fatigue properties of internal thread.

Abstract:In recent research, a novel method combined with pulse current (PC) deposition and the ultrasonic (U) field was used to fabricate pure nickel and nickel-ceria composite coatings, respectively. Morphology, crack propagation, and crystal texture were observed and analysed by using environment scanning electron microscopy (E-SEM) and transmission electron microscopy (TEM). Orthogonal experiment [L16 (45)] was designed to optimize the parameters of pulsed power and the appropriate amount of RE addition based on microhardness. Effect of RE addition and pulsed current on the mechanism of co-electrodeposition was also investigated and compared. Experimental results indicated that it produced the alloying coatings, exhibiting compact grain and amorphous state. Nano-sized RE would preferentially occupy and pad at the edge of cracked gaps and micropore to limit the growing location and space for coarse Ni grain. Furthermore, during annealing at 480 °C for 2 h, a solid-solution precipitated phase named NiCexO1-x (0<x<0.5) dispersed along the large crystal boundary, which would make RE diffused sufficiently to improve crack propagation resistance and promote densification efficiently. © 2011 The Chinese Society of Rare Earths.

Abstract:Based on comparing structural features of different tubular pumping systems and technical characteristics of cut off devices in common use, aiming at the characteristics of low head, shorter annual operation time and higher safety and reliability requirements of city flood control pumping stations, a new type shaft tubular pumping system was invented, which is composed of a shaft suction box, a tubular pump and a siphon type discharge passage with a vacuum breaker valve as cutoff device. Taking a real pumping station in Yancheng city as an example, the computational fluid dynamics method was adopted to analyze the internal flow of the new type model tubular pumping system and predict its energy performances. The time averaged Navier-Storks equations were closed by RNG k-Ε turbulent model to adapt internal flow of siphon type discharge passage with larger curvatures. The method of multi-reference frame(MRF) was used to deal with the coupling of rotating impeller and static guide vane, and SIMPLEC algorithm was adopted to achieve the coupling solution of velocity and pressure. Computational results show that the internal flow of the new type shaft tubular pumping system through preliminary optimization is smooth, and the model pumping system efficiency reaches 56.0% when the design head and the relevant discharge are 1.15 m and 0.326 m3/s respectively, and up to 68.8% when the maximum head and the relevant discharge are 1.95 m and 0.296 m3/s respectively.

Abstract:In order to prevent and eliminate vortex and the vortex tube occurred in the suction passage of two-way-reversible pumping system for the safe operation of the pump unit, an additional curved guide pier was placed on the bottom of suction passage under pump mouth. By using the CFD software the numeric simulation was made to obtain three-dimensional flow fields inside the pumping system with the additional guide pier and predict the performance of the pumping system. Combined with the model test, this paper focused on the velocity distribution of suction passage outlet, and its influences on the pump system performance. Both the computation and the measurement results showed that the additional guide pier on the bottom inside the suction passage did not effect on the velocity distribution of suction passage. The velocity evenness of suction passage outlet reach 93% with guide pier, which can meet the needs of pump operation. The performance of the pumping system was good and the high efficiency of the system at BEP is 68.89%. Experimental observations showed that the set of the guide pier could effectively prevent the vortex generation under pump inlet, the vortices were not found within the suction passage under different operation conditions. The pump ran smoothly without vibration. Comparing the calculated results with the model test results of the outlet velocity distribution of the suction passage, both of them are similar in overall structure and pump performance prediction at BEP is consistent with the test results.

Abstract:Cooling field dependence of exchange anisotropy was investigated in ferromagnetic(FM)/antiferromagnetic(AFM) bilayers with antiferromagnetic interface coupling. It shows that the exchange bias HE can change from negative to positive with increasing cooling field HCF and coercivity HC acquires a maximum near crossover of HE. Especially, effect of FM and AFM thickness on exchange anisotropy is discussed in detail. Both negative (or positive) HE and HC always decrease with increasing of FM thickness tFM, which shows good agreement with experimental observation. It demonstrates interfacial nature of the exchange anisotropy. However, AFM thickness tAFM dependence of exchange anisotropy is relatively complex. In the case of positive HE, with increasing of tAFM, HE increases and HC decreases. But, in the case of negative HE, HE decreases and HC increases with increasing tAFM.

Abstract:A particle filter tracking algorithm based on multi-feature clustering is proposed. To address the issues such as the diversity of target features, the difference between methods of feature distribution description, and the arbitrariness of feature spatial structure, the multi-features representation of target model is unified into a clustering computing framework. The mean shift based feature space analysis approach is employed to adaptively calculate the clusters in any arbitrarily structured feature space. Based on the clusters, a target probability density estimation method, which is efficient and accurate, is proposed to represent the target model. The distance between the reference target and the candidate is calculated by the similarity measure of kernel density estimation, and is taken as important information for observation in particle filter system. To efficiently enhance the utilization rate of particles, an improved particle propagation model is presented. The object tracking experiments are performed on many real image sequences by using the LUV color features and the LBP (local binary pattern) texture features. Experiment results show that the proposed algorithm can obtain high tracking accuracy and strong robustness, meet real-time demand, and provide better tracking performance comparing with other typical algorithms.

Abstract:A series of double-doped La1.85-1.5xSr 0.15+1.5xCu1-xMnxO 4 (0≤x≤0.2) samples were synthesized by the solid-state reaction method. The structural, transport and magnetic properties were studied. The superconductivity can even survive till Mn doping level to x = 0.15. It is noteworthy that the sample with x = 0.06 undergoes two superconducting transitions in the M-T curves. It is suggested that the Cu-O-Cu pdσ hybridization interaction is weakened by the superexchange interaction between the doped Mn ions and the O ions in the Cu-O-Cu paths neighboring Mn, which leads to the suppression of superconductivity. © 2011 Elsevier B.V.

Abstract:In order to investigate the resistance characteristics of flap gate, the experimental and numerical simulation studies of resistance loss of flap gate were performed. Outlet circulation of the pump has great influence on resistance loss of flap gate, so the resistance loss and the square value of flow do not show the proportional relationship. In the conditions of the same flow, efficiency decreased value of pump system was negative correlated with the open angle of flap gate. On the basis of numerical simulation, flow patterns of the outlet were analyzed with and without flap gate under designed operating condition. The resistance loss of flap gate was predicted. A good agreement was achieved between the predicted data and the experimental data under designed operating condition.

Abstract:The operating region of axial-flow pumps is greatly reduced due to the existence of unstable operating range at low flow-rate condition. The energy performance of an axial-flow pump was measured in detail, and head-flow curve with bi-saddle was obtained. Particle image velocimetry (PIV) technology was used to measure the two-dimensional flow fields at the inlet axial plane under the flow rate of 0.73Qd, 0.55Qd, 0.43Qd and 0.33Qd. The experiment results show that backflow exists at the impeller inlet close to the wall, and the backflow zone increases with the decreasing of flow rate. With the decreasing of the flow rate, the turbulence intensity obviously increases, the turbulence intensity of axial velocity is higher than one of radius velocity and the turbulence intensity near the case wall is much higher close to the hub. The flow at the inlet wall evolutes from axial direction to circumferential direction can be seen clearly by the silk lines. The experimental results indicate that the lower performance of axial flow pump at the low flow rate condition is due to the unstable flow at the inlet impeller. This provides a reference for further improvement of axial-flow pumps performance at low flow rate condition.

Abstract:Hexadecane is one of the main chemical compounds in Cooking Oil Fume Condensates (COFCs), which has been proved to influence the vegetative growth of Salvinia natans (L.) All. significantly. Its effects on the growth of S. natans were studied by using static toxicity testing method in this paper. The results showed that relative growth rate (RGR), leaves, buds and stems of S. natans were inhibited significantly when exposed to higher concentrations. Hexadecane could accelerate the leaves of S. natans becoming yellow or decomposed. Biomass went down with the increase of hexadecane concentrations. The LC50 on day 4 and day 12 after treatment were 275 mg/L and 244 mg/L, respectively. Hexadecane had no effect on the pH value and conductivity of the cultivation medium. It can be concluded that hexadecane would significantly affect the vegetative growth of S. natans., and S. natans is sensitive to hexadecane that might be useful as an indicator of hexadecane pollution in freshwater.

Abstract:Brominated flame retardant (BFR), which containing in printed circuit boards (WPCBs), brings a series of environmental and health problems. Hydrothermal technology was applied to decompose brominated epoxy resin in WPCBs at subcritical or supercritical water conditions. The brominated epoxy resin was decomposed into oil and the environmental influence of BFR was eliminated. The experiment was carried out in a 5.7 ml tube reactor and heated by a salt-bath. The variation of degradation rate of brominated epoxy resin with reaction temperature, time and additives were studied. The compositions of liquid products were analyzed by gas chromatography-mass spectrometry (GC-MS). When reaction temperature exceeded 300 °C, retention time stayed over 30 min and alkaline additive existed, more than 80% brominated epoxy resin could be mainly decomposed into phenol, which can be used as chemical material. Two different hydrothermal decomposition pathways were discussed according to the characterization of products. The results indicated that brominated epoxy resin in WPCBs could be handled effectively by hydrothermal decomposition. © 2011 Elsevier B.V. All rights reserved.

Abstract:In this work, the caffeine and some catechin compounds (+) C, EC, and EGCG were extracted from green tea by using two molecular imprinted polymers (MIPs) as sorbent materials in a multi-solid-phase extraction (SPE) process known as MISPE (molecular imprinted solid-phase extraction). To obtain synthesis of MIP, (+) catechin (and caffeine) was employed as the template, AM (and MAA) as the monomer, EGDMA as the crosslinker, and AIBN as the initiator. A solution of (+) catechin (and caffeine) (0.2mg/mL in methanol) was utilized in the solid extraction cartridges following loading, washing, and elution procedures with acetonitrile, methanol, and methanol/acetic acid (90/10, %v/v) as the solvents, respectively. This multi-solid-phase extraction protocol was applied for the extraction of caffeine and some catechin compounds from green tea. A comparison was made between the results obtained with the caffeine and (+) catechin MIP cartridges, blank polymer, and a traditional C18 reversed-phase cartridge. It was thereupon found that the recovery of caffeine by the caffeine-MIP-based sorbent used in this work was almost two and four times greater than that by a commercially available C18 material.

Abstract:A novel β-cyclodextrin/poly(vinyl alcohol) nanofibrous membrane (β-CD/PVAnfm) with the function of molecular capture was successfully prepared by electrospinning homogeneous aqueous solutions of β-CD and PVA. β-CD/PVAnfm was characterized by scanning electronic microscopy and Fourier transform infrared spectroscopy. The viscosity of β-CD/PVA solution was increased with the concentration of β-CD and high viscosity of β-CD/PVA solution was beneficial to form more uniform nanofibers. The interaction between β-CD and PVA in the solution was studied by rheological measure and 1H NMR spectra. The rheological change of electrospinning solutions was attributed to the intermolecular hydrogen bonding between β-CD and PVA in the solution, which was confirmed by 1H NMR spectra. The electrochemical measurement showed that β-CD/PVAnfm could recognize small hydrophobic molecules such as ferrocene (Fc) by forming inclusion complexes. The molecular capturing ability of β-CD/PVAnfm was increased with the amount of β-CD in composite nanofibrous membrane. The results suggested that the composite nanofibrous membrane was potentially applied to purification/separation processes, electrochemical sensor, drug delivery, and so on. © 2011 Elsevier Ltd.

Abstract:Using the atomistic nonequilibrium Green's function, we find that thermal conductance of carbon nanotubes with presence of topological lattice imperfects is remarkably reduced, due to the strong Rayleigh scattering of high-frequency phonons. Phonon transmission across multiple defects behaves as a cascade scattering based with the random phase approximation. We elucidate that phonon scattering by structural defects is related to the spatial fluctuations of local vibrational density of states (LVDOS). An effective method of tuning thermal transport in low-dimensional systems through the modulation of LVDOS has been proposed. Our findings provide insights into experimentally controlling thermal transport in nanoscale devices. © 2011 American Institute of Physics.

Abstract:The continuous effort to improve efficiency, reduce particle, and greenhouse gase emissions leads to the emergence of the concept more electric. This concept helps to boost the performance as well as the flexibility of the domestic and vehicular applications; however, on the other hand, it excessively burdens current power networks (including vehicle power systems). In order to remedy this problem, simultaneous usage of renewable sources and energy storages is encouraged. A multiconverter system is commonly adopted to process the renewable power in form of distributed generation. However, due to the discrete structure of such systems, power flow and load regulation are coordinated via communication channel, which inevitably reduces the reliability and dynamic response of the system. This paper presents the concept of multiport power electronic interface (MPEI) for renewable energy sources and storages. With a unified modular topology and highly integrated digital control system, controlled quasi-current source is achieved for each input port in both steady-state and transient power-sharing modes. MPEI analysis, modeling, design, and system operation are treated in a systematic manner in this paper. Both power stages and digital control system are implemented for a five-port MPEI. Experiments are conducted under meaningful operation scenarios. The results are presented to prove the feasibility of MPEI concept and system design methodology. © 2011 IEEE.

Abstract:A novel strategy was proposed to fabricate carbon fiber microelectrodes (CFMEs). The resultant CFMEs were characterized using scan electron microscopy (SEM) and cyclic voltammetry (CV). Compared to the conventional method, the proposed method only needs a simple heating step for achieving CFMEs without additional pulled, sealed and back-filled procedure. The electrochemical behaviors of 2,4-Dichlorophenol (2,4-DCP) at fabricated CFMEs in pH (2.0-9.0) was for the first time studied and demonstrated a two-charge and two-proton transference process. © (2011) Trans Tech Publications.

Abstract:In the mass concrete structure construction, the thermal insulation material and cooling pipe are important temperature control materials to prevent concrete from cracking. In order to select the right materials, their heat exchange coefficients should be obtained exactly. But no proper apparatus can give the parameters through simple measure. An experiment concrete block with the dimension of 50m long and 22m wide was established near a dam construction site and the corresponding inversion calculating was applied. The experiment method is presented. The measured curves and calculated curves meet well which shows the inversed parameters reliable. Then the heat exchange coefficients of the EPE insulation materials with different thickness and the HDPE pipes with different diameters are given. The application effect shows the selected materials have achieved the goal of crack prevention. The experiment and inversion method will provide reference to other cases and the heat exchange coefficients can be used in similar structures. © (2011) Trans Tech Publications, Switzerland.

Abstract:1-Octyl amine was covalently coupled to sodium alginate(NaAlg) in an aqueous-phase reaction via acidamide functions using 1-ethyl-3-(3- dimethylaminopropyl) carbodiimide hydrochloride (EDC-HCl) as a coupling reagent to provide octyl-grafted amphiphilic alginate-amide derivative(OAAD) for subsequent use in λ-cyhalothrin (LCH) microcapsule application. The structure of OAAD was confirmed by FT-IR and 1H NMR spectroscopies. The new alginate-amide derivative was used for fabricating microcapsule that can effectively encapsulate LCH by emulsification-gelation technique. The microcapsules were characterized by optical microscopy (OM), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and laser particle size analysis. The encapsulation efficiency and drug release behavior of LCH from the microcapsules were investigated. Results showed that the microcapsules were in spherical form with diameter mostly in the range of 0.5-10 μm and possessed a structure with LCH as core and OAAD as shell. The encapsulation efficiency and the release performance of the microcapsules were influenced by DS of OAAD and amount of CaCl2. The mechanism of LCH release was found to vary from anomalous to Fickian to quasi-Fickian transport with the DS of OAAD varied from 10.8 to 30.3 and the CaCl2/emulsion ratios varied from 0.09 to 0.03%. © 2011 American Chemical Society.

Abstract:A field experiment was conducted to study prediction models of rice transpiration intensity at three different growth stages (including jointing booting, heading to flowering and milk stage) at none-water layer. Correlation analysis and stepping multi-regression analysis suggested that soil moisture content of root zone, temperature in the field, relative humidity and wind speed were the four main factors affecting the transpiration intensity of semilate rice. Error analysis also showed that the multi-linear regression models of transpiration established based on soil moisture content and major meteorological factors at three different growth stages were satisfying, and the maximum relative errors are 4.39%, 1.71% and 2.81% respectively. Research results establish a basis for the calculation of semilate rice water requirement at none-water layer of paddy. © 2011 IEEE.

Abstract:Air entrapment in soil is common in cases of farmland flood irrigation or intense rain. A simple, physically based model would be more useful than the complex two-phase (gaseous and liquid phase) flow model to describe water infiltration in layered soils with air entrapment. This study proposed a modified Green-Ampt model (MGAM) to simulate water infiltration in layered soils with consideration of entrapped air. A saturation coefficient Sa was introduced in MGAM to account for the resistance effect of air entrapment on infiltration. Sa had robust physical meaning, and was approximately equal to one minus the plus of the residual air and residual water saturation degree that could be determined from the soil water retention curve equation. In MGAM, the actual water content and hydraulic conductivity of the wetted zone were determined by multiplying Sa with the saturated values. Infiltration experiments in a 300-cm-long five-layered soil column and a 280-cm-deep eight-layered field soil profile were conducted to test the applicability of MGAM. For comparison, the infiltration process was also simulated by the traditional Green-Ampt model (TGAM), in which the wetted zone was assumed to be fully saturated, and the Bouwer Green-Ampt model (BGAM), in which the hydraulic conductivity of the wetted zone was half that of the saturated hydraulic conductivity. The estimated Sa values were very close to the measured saturation degree of soil layers at the termination of the experiment. The simulation results indicated that the TGAM overestimated the infiltration rate and cumulative infiltration, whereas the BGAM underestimated the infiltration rate and cumulative infiltration. Furthermore, the depths of the wetting fronts simulated by TGAM and BGAM were considerably smaller than those measured. The MGAM provided satisfactory simulation results and adequately described the infiltration process in both the laboratory soil column and the field soil profile. © 2011 American Society of Civil Engineers.

Abstract:Functionalities of a variety of complex systems involve cooperations among multiple components; for example, a transportation system provides convenient transfers among airlines, railways, roads, and shipping lines. A layered model with interacting networks can facilitate the description and analysis of such systems. In this paper we propose a model of traffic dynamics and reveal a transition at the onset of cooperation between layered networks. The cooperation strength, treated as an order parameter, changes from zero to positive at the transition point. Numerical results on artificial networks as well as two real networks, Chinese and European railway-airline transportation networks, agree well with our analysis. © 2011 American Physical Society.

Abstract:The selective localization of carbon nanotubes (CNTs) in an immiscible polymer blend has attracted much attention. If the two component polymers could react with each other, do selectively located CNTs affect those reactions? Here, an immiscible polyester blend based on polycarbonate/poly(trimethylene terephthalate) (PC/PTT) is studied. CNTs introduced during melt mixing are selectively located in the PTT phase and on the phase interface during the middle stage of melt mixing. The interface-located CNTs can act as additional substrate to catalyze or even participate in the transesterification themselves, homogenizing the phase morphology of the matrix blend. The degree of randomness of the composite systems is increased, accompanied by a reduced number-average length of the copolymer sequences. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Abstract:The adsorptive capability of β-Cyclodextrin-cross-linked polymer(β-CDCP) for cadmium was assessed in this work using column method. It was found that the complex (Cd(II)-5-Br-PADAP) could be quantitatively retained on the β-CDCP in the pH 8.5, eluted completely with 1.5 mol·L-1 HCl. Under the optimum conditions, the linear range, detection limit (DL) and the relative standard deviation (R.S.D.) was 2.0-60.0 μg·L-1, 7.8 ng·L-1 and 2.20% (n=3, c=20.0 μg·L-1) respectively. The separation of Cd(II) was achieved from water samples with an enhancement factor of 20. Moreover, the β-CDCP could be used repeatedly and offered better recovery. The method was validated using a certified reference material, and applied for the determination of trace cadmium in water samples. © (2011) Trans Tech Publications, Switzerland.

Abstract:The invert arch floor of large plunge pool is composed of some discrete arch blocks divided by construction joints. The joint is only 1 mm wide. Under the uplift pressure, the mechanical behavior belongs to highly nonlinear problem, which is difficult to simulate by finite element method. Based on NMM (numerical manifold method), the kinematic motion process of the invert arch floor is simulated under the different uplift pressure. Calculation results show that: as the uplift pressure increasing, each arch block gradually rises, rotates, contacts with adjacent blocks and the expansion joint width between adjacent blocks reduces. When uplift pressure reaches 85Kpa, the mutation of expansion joint width emerges and the invert arch floor finishes self-lock process which indicating the invert arch floor start playing statically indeterminate role to keep stable. The bearing capacity of the floor is determined by concrete compressive strength and anchoring strength of two arch abutments. © (2011) Trans Tech Publications.

Abstract:To better embody the evolutionary characteristics, namely dynamic variety and smooth transition of network users, the method of network user identification based on evolutionary K-means clustering algorithm is proposed. Every clustering result of the sequence reflects the classification information of network user at a special period. Furthermore, the information of historical data is considered and used to adjust the clustering result of the current data. Then, the current clustering result is smoothed and will not shift dramatically from the previous clustering. The experiment results show that the method of evolutionary K-means can improve the accuracy of network user behavior analysis and the efficiency of network management.

Abstract:In order to study the effects of nitrogen (N), phosphorus (P) and potassium (K) on the yield, the appearance eligibility ratio and the contents of total glucosinolates and glucoraphanin of cauliflower, the 311-A optimization regression design was used to conduct field experiments of N, P, K fertilizer treatments using winter cauliflower variety "HB16". The models of the balanced application for N, P and K fertilizers were set up. According to the different production targets, the different optimal combinations of applying NPK fertilizers could be carried out. The results showed that the optimal combination of applying fertilizer was 372.83 kg/hm2N, 89.65 kg/hm2 P2O5 and 201.41 kg/hm2 K2O, the highest yield was 19089.25 kg/hm2. When the optimal combination of applying fertilizers was 434.20 kg/hm2N, 90.11 kg/hm2 P2O5, 213.92 kg/hm2 K2O, the eligibility products ratio could reach the highest at 84.95%. It was found that there were significant effects on the contents of total glucosinolates and glucoraphanin by applying N fertilizer, but not by P and K fertilizers. When N fertilizer application reached 408.78 kg/hm2 and 394.62 kg/hm2, total glucosinolates and glucoraphanin content would get to maximum, respectively. © 2010 Elsevier Ltd.

Abstract:A sponge-associated bacterium, Winogradskyella poriferorum strain UST030701-295T was cultured up to 100l for extraction of antifouling bioactive compounds. Five poly-ethers were isolated and partially characterized based on nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS); two of them showed inhibitory effects on biofilm formation of marine bacteria and larval settlement of macro-foulers but did not produce any adverse effects on the phenotypes of zebra fish embryos at a concentration of 5μgml-1. The effect of culture duration on the production of the poly-ethers and the bioactivity of the relevant extracts was monitored over a period of 12days. The total crude poly-ether production increased from day 2 to day 5 and the highest bioactivity was observed on day 3. The poly-ethers were found to be localized in the cellular fraction of the extracts, implying their natural occurrence. The potent bioactivity of these poly-ethers together with their high natural abundance in bacteria makes them promising candidates as ingredients in antifouling applications. © 2011 Elsevier Ltd.

Abstract:The oxidative desulfurization for a simulated oil(S content 1 540×10-6) consisting of model sulfur compounds of dibenzothiophene(DBT) and toluene solvent in a H2O2/WO3/ZrO2 oxidative system was studied. The influence of oxidation temperature, reaction time, the amount of oxidant and the dosage of catalyst on the conversion of DBT were investigated. The experimental results reveal that under an optimum oxidative desulfurization condition with the temperature of 50°C, the reaction time of 90 min, the oxidant dosage of V(oil):V(H2O2)=20:1 and the catalyst dosage of 0.02 g/mL oil, more than 96% of DBT are oxidized to dibenzothiophene sulfone(DBTOs) that can be easily removed. Furthermore, the oxidation kinetics of dibenzothiophene was investigated. The oxidation of DBT can be treated as a first-order reaction, the apparent activation energy Ea is 55.37 kJ/mol and the pre-exponential factor A is 3.35×107 min-1.

Abstract:Using layered double hydroxides (LDHs)-chitosan (Chit) composite as enzyme immobilization matrix, the developments of cholesterol biosensor were achieved by both electrooxidation and electroreduction of the enzymatic-generated hydrogen peroxide based on cholesterol oxidase (ChOx) and horseradish peroxidase (HRP). Amperometric detection of cholesterol was evaluated by holding the modified electrode at 0.55 V and 0 V (vs. SCE), for ChOx/LDHs-Chit/Pt and ChOx/HRP/LDHs-Chit/GCE, respectively. The linear dynamic ranges of anodic and cathodic detections of cholesterol were between 5 × 10-7 to 8 × 10-4 M and 4 × 10-8 to 6 × 10 -4 M, respectively. The detection limits were determined to be of 1 × 10-7 and 4 × 10-8 M with anodic and cathodic processes, respectively. At potential of 0 V, ChOx/HRP/LDHs-Chit/GCE bienzymatic mediated system exhibited excellent selectivity and stability. © 2011 Elsevier B.V. All rights reserved.

Abstract:The paper studies deeply the problem of mining the multi-dimensional frequent paths from the gigantic path data set created by a radio frequency identification (RFID) system applied to supply chain management, and proposes the Dim-path algorithm and the Path-dim algorithm, two methods for mining closed multi-dimensional frequent paths in RFID databases. Base on the characteristics of RFID data, the two methods divide RFID data into three parts of the path independent dimensions, the location data, and the duration data, and mine these parts with multi-dimensional analysis and sequential data mining to improve the efficiency of the methods. The experimental and analytical results show that the algorithms of Dim-path and Path-dim can rapidly and efficiently mine the multi-dimensional frequent path.

Abstract:The generalized coupled thermoelasticity based on the LordShulman theory is considered to study the transient thermoelastic response of functionally graded rectangular plates. The state equations of functionally graded rectangular plate subjected to time-dependent thermal loads were established by using of state space approach, in which three displacement components, three stress components, the temperature and the heat flux were chosen as state variables. By giving simply supported boundary conditions and assuming that the material properties of the plate have an exponential law distribution along the thickness-coordinate, the equations were solved by the numerical Laplace transformations and shooting methods for transient thermal responses of a three dimensional functionally graded rectangular plate due to a thermal shock on its top surface. Effects of the volume fraction distributions of material constituents on the thermal responses, including the temperature change, the displacement and the stresses distributions were investigated. © 2011 Elsevier Ltd.

Abstract:The self-assembly behavior of mixed systems consisting of amphiphilic chitosan derivatives C. n-OCMCS (n= 4, 6, 8) and the conventional cationic surfactant cetyltrimethylammonium bromide (CTAB) is investigated. Transmission electron microscopy (TEM), dynamic light scattering (DLS), small-angle X-ray diffraction (XRD), UV-vis spectra, and zeta potential measurements have been utilized to characterize the microstructures of C. n-OCMCS/CTAB mixtures in aqueous solutions. Spherical vesicles are formed spontaneously in the C. n-OCMCS (n= 4, 6, 8)/CTAB mixed systems, and the increased hydrophobic chain length of C. n-OCMCS enhances the ability to form vesicles. The addition of NaBr with higher concentrations to the vesicle system transforms vesicles into micelles, and an increase in temperature decreases the vesicle size. The results indicate that the main driving forces controlling vesicle formation may be attributed to the strong electrostatic interactions as well as the hydrophobic interactions, and also the hydrogen bonding between C. n-OCMCS molecules. © 2011 Elsevier Inc.

Abstract:A specific, sensitive and widely applicable reversed-phase high-performance liquid chromatography with fluorescence detection (RP-HPLC-FLD) method was developed for the simultaneous determination of thiamphenicol (TAP), florfenicol (FF) and florfenicol amine (FFA) in eggs. Samples were extracted with ethyl acetate-acetonitrile-ammonium hydroxide (49:49:2, v/v), defatted with hexane, followed by RP-HPLC-FLD determination. Liquid chromatography was performed on a 5μm LiChrospher C18 column using a mobile phase composed of acetonitrile (A), 0.01M sodium dihydrogen phosphate containing 0.005M sodium dodecyl sulfate and 0.1% triethylamine, adjusted to pH 4.8 by 85% phosphoric acid (B) (A:B, 35:65 v/v), at a flow rate of 1.0mL/min. The fluorescence detector of HPLC was set at 224nm for excitation wavelength and 290nm for emission wavelength. Limits of detection (LODs) were 1.5μg/kg for TAP and FF, 0.5μg/kg for FFA in eggs; limits of quantitation (LOQs) were 5μg/kg for TAP and FF, 2μg/kg for FFA in eggs. Linear calibration curves were obtained over concentration ranges of 0.025-5.0μg/mL for TAP with determination coefficients of 0.9997, 0.01-10.0μg/mL for FF with determination coefficients of 0.9997 and 0.0025-2.50μg/mL for FFA with determination coefficients of 0.9998, respectively. The recovery values ranged from 86.4% to 93.8% for TAP, 87.4% to 92.3% for FF and from 89.0% to 95.2% for FFA. The corresponding intra-day and inter-day variation (relative standard deviation, R.S.D.) found to be less than 6.7% and 10.8%, respectively. © 2011 Elsevier B.V.

Abstract:The high-temperature shear strength of asphalt mixture was confirmed by using uniaxial penetration test at 60°C. The 2D morphological characters of coarse aggregate were described in terms of shape, angularity and surface texture by using digital image processing technology. The gradation of coarse aggregate was identified based on equivalent ellipse method and sieve size correction factor. The morphological characters of coarse aggregate were extracted by MATLAB, and some characters affecting the high-temperature shear strength of asphalt mixture were proved. Euler number of image in digital topology was applied to quantify the skeleton stability of coarse aggregate. Analysis result shows that the shear strength of asphalt mixture increases due to coarse aggregates with low aspect ratio and eccentricity, high angularity index of equal ellipse perimeter and surface texture parameter. As Euler number decreases, the skeleton structure of coarse aggregate in asphalt mixture with dense framework structure becomes steadier, which leads to higher high-temperature shear strength of asphalt mixture. 9 tabs, 3 figs, 9 refs.

Abstract:In this paper, ZnO/epoxy composites with homogeneous dispersion were prepared via two simple steps: firstly, in situ preparation of zinc hydroxide (Zn(OH)2)/epoxy from the reaction of aqueous zinc acetate (Zn(Ac)2·2H2O) and sodium hydroxide (NaOH) at 30°C in the presence of high viscosity epoxy resin; secondly, thermal treatment of the as-prepared Zn(OH)2/epoxy hybrid into ZnO/epoxy composites. Meanwhile, the structure, composition and mechanical properties of the resultant products were successfully investigated. From the result of characterization we found that the composite had the optimal mechanical property at ZnO fraction of 5wt.%. Compared to pure epoxy resin, the improvement of ultimate tensile stress, elongation at break, tensile modulus and flexural strength achieved about 40.84%, 24.35%, 27.27% and 51.43%, respectively. The crack arresting mechanisms included particle matrix debonding, plastic void growth, in the composites with a stronger interface, significant plastic deformation of the matrix around the well bonded particles. At the same time, the possible reactive mechanism of the preparation of ZnO/epoxy composite was discussed in this paper. © 2011 Elsevier Ltd.

Abstract:Microreactor systems existed as a powerful tool for the continuous synthesis of quantum dots. However, the lack of structure optimization for the discrete units led to empirical determination of the length scale, and the properties of the formed products varied in different cases. In this article, the optimizations for the micromixer volume and capillary diameter were presented based on the synthesis of CdSe nanocrystals (NCs). Spectra investigation revealed that the application of a small convective mixer of 36 μL led to 1/3 increase of CdSe concentration in the crude solution. The enhanced mixing of the precursors in this case was also demonstrated favorable to achieve CdSe NCs with narrow PL width. Fast heating and uniform reaction condition achieved in a narrow channel favored the preparation of high quality CdSe NCs under short residence time. However, the application of wide channel did not necessarily result in CdSe NCs with poor quality. Here, we demonstrated that high-quality CdSe NCs with narrow full width at half maximum (FWHM) as 32 nm and high quantum yield (QY) 34.7% could be prepared using an 844 μm inner diameter capillary. Based on the obtained results, the scaled-up synthesis of CdSe NCs was demonstrated, and a high quantity of 0.8 g dry CdSe NCs powder (3.5 nm, σ ~ 8.2%) was obtained within 1 h. © 2011 Springer Science+Business Media B.V.

Abstract:Electrospinning of the biodegradable polylactide (PLA) and its composites containing carbon nanotubes (CNTs) was studied in terms of solution concentrations and solvents effects as well as CNT loadings. The results reveal that the PLA fibers obtained from the solutions using the mixed solvents of chloroform/assistant solvent (v/v 3/1) show better morphologies than those from the solutions using chloroform as the single solvent. This is due to the synergistic effect by the improved conductivity and altered viscosity with addition of assistant solvent. Moreover, the surface structure of fibers depends on the volatility of assistant solvents strongly. Using volatile acrylonitrile or acetone as the assistant solvents, the columned fibers with porous surface structure are obtained; while the flat fibers with fluted surface are formed using nonvolatile dimethyl sulfoxide as the assistant solvents. As for electrospinning of the PLA/CNT composites, the morphology of obtained fibers is closely related to the dispersion of CNTs in the fibers. At low loading levels, the CNTs can be well embedded in the PLA matrix and oriented along the fiber axis, forming nanowire structure. At high loading levels, the CNTs are mainly dispersed as entangled bundles along the fiber axis, and as a result, the obtained fibers show tortuous or misshaped morphologies. Compared with that of the neat PLA fibers, the overall morphologies of the composite fibers are more or less degraded because the presence of some small CNT aggregates in the solutions easily leads to the formation of beaded fiber structure during electrospinning. The conductivity of the obtained composite fiber mats was further studied in terms of CNT loadings. © 2011 Society of Plastics Engineers.

Abstract:In the past few decades, many face recognition methods have been developed. Among thesemethods, subspace analysis is an effective approach for face recognition. Unsuperviseddiscriminant projection (UDP) finds an embedding subspace that preserves local structure information, and uncovers and separates embedding corresponding to different manifolds. Though UDP has been applied in many fields, it has limits to solve the classification tasks, such as the ignorance of the class information. Thus, a novel subspace method, called supervised discriminant projection (SDP), is proposed for face recognition in this paper.In our method, the class information was utilized in the procedure of feature extraction.In SDP, the local structure of the original data is constructed according to a certain kind of similarity between data points, which takes special consideration of both the localinformation and class information. We test the performance of the proposed method SDP on three popular face image databases (i.e. AR database, Yale database, and a subset of FERET database). Experimental results show that the proposed method is effective. © Springer Science+Business Media, LLC. 2011.

Abstract:In this paper, the robust initial alignment problem for inertial navigation systems (INSs) is investigated. Different from most previous works only focusing on Gaussian noises (or other single disturbance), the INS error equation with multiple types of disturbances is constructed. We consider two types of disturbances, where the first type is the sensor drifts described by an exosystem, and the second one includes the nonlinear modeling uncertainties and other measurement noises. A robust filter is constructed for the concerned INS with disturbance rejection and attenuation performance. In the proposed approach, the drift estimations are applied to reject the inertial sensor drifts, H performance is applied to attenuate the norm bounded uncertain disturbances. The proposed multi-objective filter is with both disturbance rejection and attenuation performance. Finally, simulation for stationary base alignment of an INS is given to show the efficiency of the proposed approach. © 2011 Zhejiang University.

Abstract:In order to analyze the adapt ability of doubly-fed induction generator (DFIG) happens, and achieve the capability of low voltage ride through of DFIG, it is necessary to study the process of electromagnetic transient when the power grid fault happens. In this paper, using the characteristics equation of DFIG, to establish the state space equation of describing the electromagnetic transient process, and derive the analytic rule in the domain time of the current of stator and rotor dq coordinate system when the voltage drop under varying degrees. Therefore, deriving the relationship between the electromagnetic torque of DFIG during the transition mechanism with rotor excitation voltage characteristics, so to provide adequate theoretical basis for protecting the transmission system. In order to verify the correctness of theoretical analysis, the voltage sag transient model of DFIG of 1.5MW on matlab simulation platform is created. The simulation results show that the waveforms of analyzing the transient voltage drop are basically the same, it means the transient analysis is correct. Through the analysis can help to assess the operation characteristics of voltage sag and the design the control technology. © 2011 IEEE.

Abstract:Hexaphenylbenzene-based porous organic polymers are prepared smoothly through palladium-catalyzed C-C coupling polymerization. According to the obtained nitrogen physisorption isotherms, the Brunauer-Emmett-Teller specific surface area for these polymers varies between 742 and 1148 m2 g -1. Gravimetric hydrogen adsorption isotherms show that the adsorption capacity for hydrogen is up to 1.5 wt % at 1.13 bar and 77 K. Thanks to the propeller-like structure, unique electronic feature, and efficient preparation, hexaphenylbenzene can be taken as a promising building block for designing porous polymers with special properties. © 2011 American Chemical Society.

Abstract:The E-government environment which is improving provides new governance tool for China in transformation period. Meanwhile, the public have more chances to participate in political activities and public policy process. First, E-government establishment facilitates the overt information culture, which betters the information asymmetric situation between the public and government officials. In this way, the public's network public-opinions expression gains its rational premise. Second, the interacting political platform provided by E-government supplies physical basis for government's response mechanism, which makes the deep dynamic force for the public to express opinions through network. Third, E-democracy, as the accompaniment of E-government, has the characteristics of low thredhold and fast transmitting speed, which can makes network public-opinion expression the best preference of the public. Therefore, network becomes the dialogue and negotiation platform in public policy process of the public. © 2011 IEEE.

Abstract:The design of rational cryptographic protocols is a recently created research area at the intersection of cryptography and game theory. At TCC'10, Fuchsbauer et al. introduced two equilibrium notions (computational version of strict Nash equilibrium and stability with respect to trembles) offering a computational relaxation of traditional game theory equilibria. Using trapdoor permutations, they constructed a rational t-out-of n sharing technique satisfying these new security models. Their construction only requires standard communication networks but the share bitsize is 2 n |s|∈+∈O(k) for security against a single deviation and raises to (n∈- ∈t∈+∈1)&bull(2n|s|∈+∈O(k)) to achieve (t∈-∈1)-resilience where k is a security parameter. In this paper, we propose a new protocol for rational t-out-of n secret sharing scheme based on the Chinese reminder theorem. Under some computational assumptions related to the discrete logarithm problem and RSA, this construction leads to a (t∈-∈1)-resilient computational strict Nash equilibrium that is stable with respect to trembles with share bitsize O(k). Our protocol does not rely on simultaneous channel. Instead, it only requires synchronous broadcast channel and synchronous pairwise private channels. © 2011 Springer-Verlag.

Abstract:An ultrasensitive electrochemical method for simultaneous determination of lead and cadmium was first developed using the novel bismuth-Nafion-medical stone doped disposable electrode (an improved wax-impregnated graphite electrode). Through the synergistic sensitization effect of the resulting composite material, the disposable electrode showed remarkable electrochemical responses to lead and cadmium. The oxidation of the two metals produced two well-defined and separated square wave peaks at about -0.62V for Pb2+ and -0.85V for Cd2+, respectively. The effects of the amount of medical stone, concentration of Nafion, thickness of bismuth, pH of buffer solution, deposition potential, accumulation time, voltammetric measurement and possible interferences were investigated in detail. Under the optimal conditions, the fabricated electrode exhibited linear ranges from 2.0 to 12.0μgL-1 with detection limit of 0.07μgL-1 for lead and 2.0-12.0μgL-1 with detection limit of 0.47μgL-1 for cadmium. The assay results of heavy metals in wastewater with the proposed method were in acceptable agreement with the atomic absorption spectroscopy method. © 2011 Elsevier B.V.

Abstract:In this work, thermal behaviors and viscoelasticity of the PPS/epoxy resin mixtures prepared by melt mixing were studied, and the rheology was used as a tool to further explore the relation between chain structures and properties of the mixtures. The results show that the epoxy resin can promotes degradation and branching of the PPS during melt mixing due to its poor thermal stability. The formation of long chain branched and partly crosslinked structures in the mixtures together with the residual decomposed components hence result in broadening of molecular weight distribution in comparison with those of the neat PPS. As a consequence, the mixtures show the viscoelastic behaviors far different from the neat PPS: the presence of crosslinked structure leads to the strong solid-like responses in the small amplitude oscillatory shear (SAOS) flow, and the presence of long chain branched structure to the weak strain overshoots in the large amplitude oscillatory shear (LAOS) flow. Moreover, after quiescent annealing, a strain-scaling transient stress behavior is observed in the mixtures in the reverse flow. © 2011 Published by Elsevier B.V.

Abstract:A novel biosensor is developed based on immobilization of proteins on nanoflake-like SnS2 modified glass carbon electrode (GCE). With glucose oxidase (GOD) as a model, direct electrochemistry of the GOD/nanoflake-like SnS2 is studied. The prepared SnS2 has large surface area and can offer favorable microenvironment for facilitating the electron transfer between protein and electrode surface. The properties of GOD/SnS2 are characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), UV-vis spectroscopy, Fourier transform infrared spectroscopy (FTIR) and cyclic voltammetry (CV), respectively. The immobilized enzyme on nanoflake-like SnS2 retains its native structure and bioactivity and exhibits a surface-controlled, reversible two-proton and two-electron transfer reaction with the apparent electron transfer rate constant (ks) of 3.68s-1. The proposed biosensor shows fast amperometric response (8s) to glucose with a wide linear range from 2.5×10-5M to 1.1×10-3M, a low detection limit of 1.0×10-5M at signal-to-noise of 3 and good sensitivity (7.6±0.5mAM-1cm-2). The resulting biosensor has acceptable operational stability, good reproducibility and excellent selectivity and can be successfully applied in the reagentless glucose sensing at -0.45V. It should be worthwhile noting that it opens a new avenue for fabricating excellent electrochemical biosensor. © 2011 Elsevier B.V.

Abstract:A novel method of dynamic hand gesture recognition based on Speeded Up Robust Features (SURF) tracking is proposed. The main characteristic is that the dominant movement direction of matched SURF points in adjacent frames is used to help describing a hand trajectory without detecting and segmenting the hand region. The dynamic hand gesture is then modeled by a series of trajectory direction data streams after time warping. Accordingly, the data stream clustering method based on correlation analysis is developed to recognize a dynamic hand gesture and to speed up calculation. The proposed algorithm is tested on 26 alphabetical hand gestures and yields a satisfactory recognition rate which is 87.1% on the training set and 84.6% on the testing set. © 2011 IEEE.

Abstract:The performance of two types of Chinese screw nails in connections between sheathing and wood frame was assessed using ASTM-F1575-03. Specimens were tested in groups of 10, and both parallel-to-grain and perpendicular-to-grain specimens were tested in the case of ASTMF1676-03. It was found that the type of nail had little effect on the performance of nail joints. Finally a modified model suitable to domestic nails in two directions was established on the basis of Foschi's exponential model. The model provides useful data on the performance of sheathing-tolumber connections. © (2011) Trans Tech Publications, Switzerland.

Abstract:Traditional cold extrusion process of internal thread is only fit for processing low-intensity and high plasticity metals such as non-ferrous metals and low-carbon steel. But the internal thread of the key parts such as airplane and high speed train is processed with high-strength steel. During cold extruding high-strength steel internal thread, the effects of lubricant, workpiece bottom hole diameter, extrusion speed and extrusion times on wear and fracture of the tap and manufacturing quality of the internal thread are great. The process of cold extrusion of Q460 high-strength steel internal thread is studied through experiments. The effects of lubricant, workpiece bottom hole diameter, extrusion speed and extrusion times on extrusion torque and extrusion temperature is analyzed. And the ideal internal thread is obtained through optimizing technological parameters. It provides a new basis for improving the surface quality and the fatigue property of internal thread. The test results show that Q460 high-strength steel internal thread is better formed by cold extrusion through one-step forming technology. The fluidic thin film lubricant whose viscosity number is between 10 and 12 is selected. The best range of workpiece bottom hole diameter is between 21.20 mm and 21.30 mm. And the generally selected extrusion speed is between 30 and 60 mm · min-1. ©2011 Journal of Mechanical Engineering.

Abstract:We proposed an idea for overcoming the difficulties met by the application of colloidal photonic crystal in flat-panel displays, such as overcoming the viewing angle dependence, displaying a complicated image, and, how to control the brightness and saturation of each pixel. In our strategy, nanospheres were firstly self-assembled into uniform spherical units, and then the colloidal crystal units were patterned as pixels. This method was favorable to realize the fabrication of display device in a large scale, with controllable uniformity and easily pattern designing. The problem that display colors varies with the observation angle can probably be adequately corrected through the homogeneity derived from the spherical symmetry of the colloidal crystals. Nematic liquid crystals were infiltrated into the voids of the inverse opaline colloidal crystal unit, and the saturation of the pixels can be controlled by utilizing the field response feature of the liquid crystals. © 2011 Elsevier B.V.

Abstract:The multiple regression method is commonly used in the freight quantity prediction because of its simple and easy. How to establish the prediction model is a question worthy of being discussed, when we want to improve the precision according to different types of cities and independent variables. This paper analysed the character of industrial structure and discovered the rule of freight quantity and unit GDP freight quantity by the example of the city Yangzhou. The paper established two prediction models by the ways of multianalysis. The first model was the relationships between freight quantity and some independent variables including Social consumable retail turnover, GDP, the first industrial value of output, the second industrial value of output and the third industrial value of output; The second model was the relationships between unit GDP freight quantity and other independent variables including the scale of the first industry, the scale of the second industry and the scale of the third industry. Finally, the first model was proved to be more practicality and better on application in contrast with the second one in forecasting of freight quantity. © 2011 IEEE.

Abstract:The improvement of storage stability can reduce the segregation degree of modified bitumen to maintain its performance. In order to appraise the stability of the rubber powder modified bitumen and seek the methods for the improvement of its stability, tests were done to analyze the effect of microwave radiation and stabilizer on the stability of the rubber powder modified bitumen. The tests indicate that microwave radiation can improve the stability of the rubber powder modified bitumen, and when the dosage of the stabilizer is 5% of the rubber powder's quantity, the improvement on the stability is best. This paper can provide reference and guidance for the engineering application of rubber powder modified bitumen. © 2011 IEEE.

Abstract:The copolymerization of aniline and 5-aminosalicylic acid (ASA) in H 2SO4 solution was first carried out on a glassy carbon electrode using cyclic voltammetry. The spectra of IR and 1H NMR demonstrated the presence of -OH group, -COOH group, and free radical in the polymer, indicating that the copolymerization of aniline and ASA took place under the electrolysis to form poly(aniline-co-5-aminosalicylic acid) (PAASA). The electric properties of PAASA are strongly dependent on the monomer concentration ratio in a reaction mixture and the upper switching potential used for the synthesis of the copolymer and the electrode materials. PAASA synthesized under the optimal conditions has a good redox activity from pH < 1 to pH 12.0; and in particular, only a 37.6% decay of the redox activity was observed after consecutive cycles from pH 4.0 to 12.0 based on cyclic voltammograms. The spectra of 1H NMR revealed some unexpectedly magnetic properties of the deprotonated PAASA. This would be the primary cause why PAASA still holds a high redox activity at pH 12.0. The conductivity of PAASA is 0.58 S cm-1 that is lower than that of polyaniline. © 2011 Elsevier B.V. All rights reserved.

Abstract:Co-doped Bi5FeTi3O15 thin films (BFCT-x, Bi5Fe1-xCoxTi3O15) were prepared using a sol-gel technique. XRD patterns confirm their single phase Aurivillius structure, and the corresponding powder Rietveld analysis indicates the change of space group around x = 0.12. The magnetic hysteresis loops are obtained and ferromagnetism is therefore confirmed in BFCT-x thin films. The remanent magnetization (Mr) first increases and reaches the maximum value of 0.42 emu/cm3 at x = 0.12 due to the possible Fe 3+-O-Co3+ ferromagnetic coupling. When x = 0.25, the Mr increases again because of the dominant Fe3+-O-Co 3+ ferromagnetic coupling. The remanent polarization (2Pr) of BFCT-0.25 was measured to be as high as 62 μC/cm2, a 75% increase when compared with the non-doped BFCT-0 films. The 2Pr remains almost unchanged after being subjected to 5.2 × 109 read/write cycles. Greatly enhanced ferroelectric properties are considered to be associated with decreased leakage current density. © 2011 Chinese Physical Society and IOP Publishing Ltd.

Abstract:A physical model test was adopted to study the characteristics of pressure fluctuation of reversible pumping system for irrigation and drainage by performance and cavitation test. Three measuring points were arranged in front-end of inlet passage, the back-end of discharge passage and outlet of guide vane. The results show that the maximum relative amplitudes of pressure fluctuation at front-end of inlet passage, the back-end of discharge passage and outlet of guide vane were 0.22, 1.10 and 1.20 respectively. With the increase of flow rate, the relative amplitude of pressure fluctuation increased in the front-end of inlet passage and the back-end of outlet passage, while the relative amplitude decreased first and then increased in outlet of guide vane. In the cavitation test the relative amplitude of pressure at outlet of guide vane increased when the intake pressure decreased to a certain value. The relative amplitudes of pressure fluctuation at the measuring points under different rotational speed varied with the lifting head in the same trends. For the same head, the relative amplitude increased with the increase of rotation speed in the front-end of inlet passage and the back-end of discharge passage, while no significant regularity was found in the relationship of outlet of guide vane and variation speed.

Abstract:The flow fields in a rotating impeller, near the volute tongue of a centrifugal pump, were measured by the 2-D PIV technique. At the flow rate of Q/Qbep=0.52, a counter clockwise recirculation flow existed on the blade pressure-side, when the blade was close to the volute tongue, a clockwise recirculation flow occurred on the blade suction-side. At the flow rate of Q/Qbep=1.0, a jet/wake flow existed at the exit of the impeller. The results show that the effects of the volute tongue on the relative velocity distribution are more significant at the low flow rate condition than at the best efficiency point.

Abstract:In order to directly obtain operation parameters, energy performances of large pumping stations were determined on the spot and analyzed. The discharges of water pumps were measured with five-hole probes and ADCP (acoustic doppler current profiler). Pump assembly head, input power of electrical motors and pump assembly efficiency were obtained through the data measured by measuring apparatus of the pumping station. The test precision of discharge and efficiency was analyzed. The efficiency conversion methods from model to prototype of the pump and the pump assembly were checked. The results indicate that the velocity distribution in cross section measured with five-hole probes can repeat very well, which stands for the actual axial velocity distribution in cross section. The test precision of the discharge and the efficiency could be controlled within 2.0%, which could meet the demand of field test of large pumping stations. The pump discharge and pump assembly efficiency are 11.8378 m3/s, 55.998% respectively when pump assembly head is 1.73 m, which meets the design demands of the pump assembly. The efficiency of prototype pump and pump assembly is obviously higher than that of model respectively because of size effect, and could be predicted accurately based on model efficiency by related suitable formulas.

Abstract:In order to compare the rheological properties of different modified asphalts in a wide frequency range, base asphalt and four kinds of modified asphalts of Styrene-Butadiene-Styrene (SBS), high-elasticity, high-viscosity and high-strength asphalts were determined by dynamic mechanical analysis (DMA). By strain sweep test, it is found that the linear viscoelastic range of several modified asphalts is lower than that of base asphalt for the same complex modulus value. By frequency sweep test within the linear viscoelastic range, complex modulus and phase angle master curves were constructed based on time-temperature superposition principle to identify the performance of different modified asphalts. The results show that high-elasticity modified asphalt shows a marked improvement of temperature susceptibility and elastic recoverability with the shallowest complex modulus master curve and the lowest phase angle. High-viscosity and SBS modified asphalts have similar rheological properties, while the high-tempe-rature performance of the former is better than that of the latter. High-strength modified asphalt has the biggest complex modulus in full frequency range with the best rutting-resistance.

Abstract:According to the forming process of cold-extruded internal thread, the microstructure at the surface of cold-extruded internal thread was investigated. The corrosion resistance was analyzed from the changing perspective of surface status of cold-extruded internal thread. The results showed that the fibrous structure of the metal surfaces on the root of thread was pressed and refined to distinguish the grains difficultly. The metal structure appeared to be streamline type and distributed along the normal direction of the tooth surface. The hardening layers of cold-extruded internal thread had an adverse effect on corrosion, and it reduced corrosion degree at the surface of the sample in the same corrosive environment, and mostly avoided producing corrosion pits to cause local stress concentration. Cold-extruded internal thread had better corrosion resistance.

Abstract:For the ferromagnetic (FM)/antiferromagnetic (AFM) bilayers, both negative and positive exchange bias HE have been observed for low and high cooling field HCF, respectively. The thickness dependence of HE and coercivity HC have been investigated for the cases of negative and positive HE. It is found that the negative HE and the positive one have similar FM thickness dependence that is attributed to the interfacial nature of exchange bias. However, the AFM thickness dependence of positive HE is completely contrary to that of the negative one, which clearly demonstrates that the AFM spins play different roles for the cases of positive and negative HE. In particular, the AFM thickness of positive HE was first highlighted by an AFM spin canting model. These results should be attributed to the interfacial spin configuration after field cooling procedure. © 2011 Elsevier B.V. All rights reserved.

Abstract:The problems of perturbation and expression for the generalized inverses of closed linear operators in Banach spaces and for the Moore-Penrose inverses of closed linear operators in Hilbert spaces are studied. We first provide some stability characterizations of generalized inverses of closed linear operators under T-bounded perturbation in Banach spaces, which are exactly equivalent to that the generalized inverse of the perturbed operator has the simplest expression T+(I+δTT+)-1. Utilizing these results, we investigate the expression for the Moore-Penrose inverse of the perturbed operator in Hilbert spaces and provide a unified approach to deal with the range preserving or null space preserving perturbation. An explicit representation for the Moore-Penrose inverse of the perturbation is also given. Moreover, we give an equivalent condition for the Moore-Penrose inverse to have the simplest expression T†(I+δTT†)-1. The results obtained in this paper extend and improve many recent results in this area. © 2010 Elsevier Inc. All rights reserved.

Abstract:The electrochemical behavior of ortho-phenylphenol (OPP) at a disposable electrode (an improved wax-impregnated graphite electrode) in the presence of sodium dodecyl sulfate (SDS) was studied for the first time. The results demonstrated that the electrocatalytic oxidation process of OPP was accompanied with two-charge-two-proton transference. The electronic transmission coefficient (α) and diffusion coefficient (D R) for OPP were calculated to be 0.8126 and 3.61 × 10-2 cm2/s, respectively. The electrochemical signal was apparently improved by SDS at the disposable electrode and the oxidative peaks current was proportional to the concentration of OPP over the range from 1.0 × 10-9 to 4.0 × 10 -6 mol/L with the detection limit of 8.7 × 10-10 mol/L. This novel and highly sensitive method can be successfully applied to detect OPP in the orange rind sample. © 2011 Science China Press and Springer-Verlag Berlin Heidelberg.

Abstract:Sn-doped ZnO nanorods were fabricated by a hydrothermal route, and characterized by X-ray diffraction, field emission scanning electron microscope, UV-vis spectroscopy, Raman spectra, solid-state nuclear magnetic resonance (NMR) spectra, and room temperature photoluminescence spectroscopy. Solid-state NMR result confirms that Sn4+ was successfully incorporated into the crystal lattice of ZnO. Room temperature photoluminescence showed that all the as-synthesized products exhibited a weak UV emission (380 nm) and a strong visible emission (540 nm), but the intensities of the latter emission increased with increase in Sn concentration. The improvement of visible emission at 540 nm in the Sn-doped ZnO samples was suggested to be a result of the lattice defects increased by doping of Sn in zinc oxide. In addition, the photocatalytic studies indicated that Sn-doped ZnO nanorods are a kind of promising photocatalyst in remediation of water polluted by some chemically stable azo dyes. © 2011 Elsevier Ltd.

Abstract:A glass-slice was used as a template to induce formation and assembly of aragonite. Thermodynamic theory was applied to explain the production of the aragonite. Transformation of three-dimensional nucleation to template-based two-dimensional surface nucleation caused the production of aragonite. Hemisphere, twinborn hemisphere and flower-shaped particles were produced by direction of the glass-slices. Planes were always appeared in these as-synthesized samples because the nucleation and the growth of these samples were adsorbed at the surfaces of the glass-slices. The formation mechanism of the as-formed sample was proposed. Compared with organic template, the present study provides a facile method to apply inorganic template to prepare functional materials. © 2011 Elsevier Ltd. All rights reserved.

Abstract:This research selected the representative bracket sets (Dougong) of Yingxian Timber Pagoda as the investigating object and adopted physical model testing method to examine the load transferring mechanism and deformation characteristic of the bracket sets. Appropriate mechanical parameters for the construction of the simplified bracket model were proposed. In this experimental research, three typical bracket sets at the key positions of the pagoda, which were the bracket set on column, bracket set between columns, and bracket set at corner, were made into the archetypal models by the scale of 1:3. By means of vertical loading test, the N-ΔV curve and compress stiffness of the bracket sets before split of the timber were obtained. Furthermore, horizontal low cyclic loading tests under the vertical loading action were carried out to obtain the N-P-ΔH curve and skeleton curve of the bracket sets, and to study the lateral displacement characteristic and energy dissipation capability of the bracket sets. The research results indicated that the vertical compressive stiffness of the bracket sets depends on the bearing area and elasticity modulus of members located on central axis. The main failure pattern is the vertical split of cap block under shear and compression. The horizontal split at the weak internal groove of axial bracket arm is the failure pattern of the bracket set under horizontal cyclic loading. The lateral displacement stiffness is increased along with the vertical load increases. The friction and shear of interfaces between members is a primary means to energy dissipation of the bracket set.

Abstract:In order to improve the understanding of soil arching effect in the piled embankment, a series of three-dimensional model tests were carried out. The stress reduction ratio and the vertical stress distribution in the embankment fill were studied in detail. Based on the measured and the computed results, the applicability of Terzaghi method and Hewlett & Randolph method were verified. Three-dimensional finite element analysis was also performed in this research; the computed orientation of maximum principal stresses, the stress level and the settlement pattern were analyzed in detail. Based on the test and numerical results, it is found that the value of stress reduction ratio computed by Terzaghi method is closed to that of Hewlett & Randolph method; but the vertical stress distributions of the two methods are different considerably. If the failure surface observed from the numerical result is used, the prediction of vertical stresses using Terzaghi's method is found to be coincident with the measured value.

Abstract:A novel photoelectrochemical sensor for detection of the organophosphorus pesticide (OP) dichlofenthion using nanometer-sized titania coupled with a screen-printed electrode is presented. Nonelectroactive dichlofenthion can be indirectly determined through the photocatalytical degradation of dichlofenthion with nanometer-sized titania. The electrochemical characterization and anodic stripping voltammetric performance of dichlofenthion were evaluated using cyclic voltammetric (CV) and differential pulse anode stripping voltammetric (DPASV) analysis, respectively. DPASV analysis was used to monitor the amount of dichlofenthion and provide a simple, fast, and facile quantitative method for dichlofenthion. Operational parameters, including the photocatalysis time, pH of buffer solution, deposition potential, and accumulation time have been optimized. The stripping voltammetric response is linear over the 0.02-0.1 and 0.2-1.0 μmol/L ranges with a detection limit of 2.0 nmol/L. The assay result of dichlofenthion in green vegetable with the proposed method was in acceptable agreement with that of the gas chromatograph-mass spectrometer (GC-MS) method. The promising sensor opens a new opportunity for fast, portable, and sensitive analysis of OPs in environmental samples. © 2011 American Chemical Society.

Results of node degrees for the Northern Hemisphere (NH) mid-high latitude (30° N-90° N) circulation system (NHS) networks with and without the Arctic Oscillations (AO), the North Atlantic Oscillations (NAO) and the Pacific-North American pattern (PNA) demonstrate that the teleconnections greatly shorten the mean shortest path length of the networks, thus being advantageous to the rapid transfer of local fluctuation information over the network and to the stability of the NHS. The impact of the AO on the NHS connection structure is most important and the impact of the NAO is the next important. The PNA is a relatively independent teleconnection, and its role in the NHS is mainly manifested in the connection between the NHS and the tropical circulation system (TRS). As to the Southern Hemisphere mid-high latitude (30° S-90° S) circulation system (SHS), the impact of the Antarctic Arctic Oscillations (AAO) on the structural stability of the system is most important. In addition, there might be a stable correlation dipole (AACD) in the SHS, which also has important influence on the structure of the SHS networks. © 2011 Chinese Physical Society and IOP Publishing Ltd.

Abstract:A method of dynamic hand gesture recognition based on SURF (speeded up robust feature) tracking is proposed. The main characteristic is that the hand trajectory is described only by tracking the dominant movement directions of matched SURF points in adjacent frames with no need of the previous detection and segmentation of the hand region. The dynamic hand gesture is then modeled by a series of trajectory direction data streams after time warping. Accordingly, the data stream clustering method based on correlation analysis is developed to recognize a dynamic hand gesture and to speed up calculation. The proposed algorithm is tested on 26 alphabetic hand gestures and yields a satisfactory recognition rate, which is 87.1% on the training set and 84.6% on the testing set. Its successful application to the motion control of our self-developed robot Hunter also establishes the effectiveness of the approach.

Abstract:The binomial tree method (BTM), first proposed by Cox et al. (1979) [4] in diffusion models and extended by Amin (1993) [9] to jumpdiffusion models, is one of the most popular approaches to pricing options. In this paper, we present a binomial tree method for lookback options in jumpdiffusion models and show its equivalence to certain explicit difference scheme. We also prove the existence and convergence of the optimal exercise boundary in the binomial tree approximation to American lookback options and give the terminal value of the genuine exercise boundary. Further, numerical simulations are performed to illustrate the theoretical results. © 2011 Elsevier B.V. All rights reserved.

Abstract:Cr-doped ZnO nanowires were fabricated by a solvothermal route from Zn(NO3)26H2O, Cr(NO3) 39H2O and NaOH. Inductively coupled plasma optical emission spectroscopy, X-ray diffraction, transmission electron microscopy, and high resolution transmission electron microscopy results confirmed the doping of Cr into ZnO lattices. UV-vis absorption spectra of both pure ZnO and Cr-doped ZnO displayed a band gap absorption peak at about 365 nm. However, compared with pure ZnO, an additional broad tail from approximately 400 nm to 750 nm appeared in the UV-vis absorption spectrum of Cr-doped ZnO. The photocatalytic studies indicated that the as-synthesized Cr-doped ZnO nanowires were a kind of promising photocatalyst in remediation of water polluted by some chemically stable azo dyes under visible light. © 2011 Elsevier B.V.

Abstract:Inspired by mineralization in biological organisms, fabrication of higher ordered CaCO3 crystals modified by surfactants has received much attention. In our present work, mixed surfactants of hexadecyl(trimethyl)azanium bromide and sodium dodecyl sulfate were used to mediate the nucleation and growth of CaCO3 crystals. When the concentration of sodium dodecyl sulfate in the solution is constant (0.1mM), the polymorph of CaCO3 crystals changed from pure vaterite to pure aragonite with increase of the ratio of hexadecyl(trimethyl)azanium bromide to sodium dodecyl sulfate. Various morphologies of vaterite and aragonite were obtained. Based on the time-resolved experiments, we suggest that the flower-like CaCO3 formed via aggregation of hexagon-like vaterite induced by the surfactants. More importantly, we realized that a cluster-shaped morphology of aragonite was produced through the nucleation of aragonite at the surfaces of the hexagon-like vaterite. © 2011 Elsevier Inc.

Abstract:Choosing low-melting-point Ca(NO3)2•4H 2O and high-reactive-activity TiO2 nanocrystals as the raw materials, a simple and cost-effective route was developed for the synthesis of CaTiO3 nanoparticles at 600 °C, which is much lower than that (about 1350 °C) used in the conventional solid state reaction methods. X-ray diffraction, energy dispersive X-ray spectroscopy and field emission scanning electron microscopy revealed the formation of orthorhombic phase CaTiO 3 nanoparticles with oxygen-deficiency at the surface. UV-vis absorption spectrum of the as-obtained CaTiO3 nanoparticles displayed an absorption peak centered at around 325 nm (3.8 eV), together with a tail at lower energy side. Room temperature photoluminescence spectrum of the as-obtained CaTiO3 nanoparticles upon laser excitation at 325 nm demonstrated a strong and broad visible light emission ranging from about 527 to 568 nm, which may be originated from the surface states and defect levels. © 2011 Elsevier B.V.

Abstract:Poly (styrene-n-butyl acrylate-methyl methacrylate) (PSBM)/silica nanocomposite was prepared by emulsion polymerization in the presence of oleic acid surface modified nanosilica. The structure, morphology, size, and size distribution were characterized by Fourier transform infrared (FTIR), transmission electron microscopy (TEM), and dynamics laser scattering. The chemical bond was formed between PSBM and nanosilica revealed by FTIR and TEM studies. The composite particles with an averaged diameter ranging from 30 to 80 nm have the core-shell structure. The effect of silica content on the glass transition temperature Tg, pyrolyze temperature, and rheological behavior of PSBM composites was systematically investigated. The results indicated that the addition of nanosilica could effectively inhibit chain movement, and improved the pyrolyze temperature of PSBM. The steady viscosity and dynamic modulus were strongly dependent on the content and distribution of nanosilica in PSBM nanocomposites. © 2011 Wiley Periodicals, Inc.

Abstract:The main concern of this paper is the perturbation problem for oblique projection generalized inverses of closed linear operators in Banach spaces. We provide a new stability characterization of oblique projection generalized inverses of closed linear operators under T-bounded perturbations, which improves some well known results in the case of the closed linear operators under the bounded perturbation or that the perturbation does not change the null space. © 2011 Published by Elsevier Inc.

Abstract:Thermal stratification is a common phenomenon in deep lakes and reservoirs, which often results in water-quality deterioration, including such problems as hypolimnetic anoxia, the release of pollutants from sediments, and algal blooms. Hypolimnetic oxygenation and destratification are the two commonly used methods for resolving these water-quality problems. A new water-quality improvement device, the water-circulating aerator, was designed to destratify lakes and reservoirs, by circulation and oxygenation of upper and lower layers of water. The design of the structure of the water-circulating aerator is detailed. Three mathematical models were built to optimize this structure, estimate the rate of water flow in the aerator, and calculate the rate of oxygen transfer from air bubbles to water in the aerator. These models were verified by experiments. The water-circulating aerator system has been successfully applied in a stratified reservoir to increase dissolved oxygen to reduce the releasing of ammonia-nitrogen from sediments under anoxic conditions. © 2011 American Society of Civil Engineers.

Abstract:In the analysis on whole structural life-cycle, there are two important factors to need to be considered. One is the determination of design service life of structure, and another is design of structure based on service life. After analyzing deeply the influence factors of life-time index, it can be found that the design service life of structure not only depends on technology level, functional requirement and economic cost factors of structures, but also relate with the specific environmental conditions, using conditions and maintenance conditions of structures. So that, an analysis method of determined design service life of structure is given in this paper. For design of structure on service life, from the view of whole structural life-cycle, a probability reliability-based analysis method of structural service life design and re-design is proposed in this paper. By updating constantly design parameters, the correctness of predicted service life is improved gradually. © (2011) Trans Tech Publications.

Abstract:In order to improve the seismic capacity of short-limb shear wall, two kinds of unbonded post-tensioned short-limb shear wall based on unbonded post-tensioned connections were put forward: (1) direct assembly short-limb wall; (2) hybrid assembly short-limb wall. The quasi-static cycle tests of two reduced scale specimens were conducted to simulate the seismic performance of 8-story symmetric double short-limb shear walls. The test results verified the basic design concept of unbonded post-tensioned short-limb shear wall, which requires that under strong earthquake action, the main part of coupling beam remains elastic and plastic deformation focus on the connection region of limbs and coupling beams. Therefore, the new short-limb shear wall is easier to fix. The test results also show the energy dissipation capacity of hybrid assembly short-limb wall is higher than that of direct assembly short-limb wall due to deformed bar crossing the interface between limbs and coupling beams. © (2011) Trans Tech Publications.

Abstract:The aim of this paper is to introduce a virtual crack closure technique based on EFG method for thread-shape crack. The cracked component is discretized and the displacement field is determined using a coupled FE/EFG method, by which EFG nodes are arranged in the vicinity of crack tip and FE elements in the remain part in order to improve computational efficiency. Two typical parameters, nodal force and crack opening displacement attached to crack tip are calculated by means of setting up an auxiliary FE zone around crack tip. Strain energy release rate (SERR), further stress intensity factor (SIF) are determined by the two parameters. The method to calculate SIF is named as virtual crack closure technique based on EFG method. It is showed by several numerical examples that using the method presented in this paper, SIF on the crack tip can be obtained accurately. © (2011) Trans Tech Publications, Switzerland.

Abstract:In this investigation, the mutual solubility for the ternary sodium 3-nitrobenzenesulfonate + sodium 4-nitrobenzenesulfonate + water system was determined at (283.15, 303.15, and 323.15) K. The phase diagrams of the system were constructed based on the measured solubility. The solid phases formed in the studied system were confirmed by Schreinemaker's wet residue method. In addition, the density of the equilibrium liquid phase was obtained. At (283.15, 303.15, and 323.15) K, there are two pure solids formed which correspond to sodium 3-nitrobenzenesulfonate and sodium 4-nitrobenzenesulfonate in the ternary sodium 3-nitrobenzenesulfonate + sodium 4-nitrobenzenesulfonate + water system. Besides, the adduct of sodium 3-nitrobenzenesulfonate with sodium 4-nitrobenzenesulfonate, in which the mole ratio of the two compositions is 1:1, was formed at 323.15 K. © 2011 American Chemical Society.

Abstract:Ultrafine CeO2 nanoparticles were synthesized directly via solvothermal treatment of Ce(NO3)3 · 6H 2O powder in toluene at 180 °C for 48 h, and characterized by X-ray diffraction (XRD), Raman, X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), and UV-vis absorption spectrum. The results from XRD, Raman and XPS revealed the formation of pure cubic phase CeO2 with some oxygen vacancies. The TEM image disclosed that the as-synthesized CeO2 comprised nanoparticles of about 5-8 nm. The UV-vis absorption spectrum showed that the as-synthesized CeO2 nanoparticles had a wide UV absorption band centered at around 326 nm (3.8 eV). © (2011) Trans Tech Publications.

Abstract:Novel microwave synthesis cationic hemicelluloses from sugarcane bagasse were obtained by quaternization with CHMAC using sodium hydroxide as a catalyst in microwave synthesis condition. The parameters including the dosage of hemicellulose/CHMAC, the microwave time and the microwave power were optimized and the extent of quaternization was measured by zeta potential. As paper additive, the effect of cationic hemicellulose on bleached bagasse was researched. Then pulp handsheet properties were studied. The results indicated that adding the cationic hemicellulose could increase paper mechanical strengths, and its effect was better than original bleached bagasse pulp. At the dosage of 0.8% on oven dried pulp, paper tensile index, tensile strength, breaking length, burst index and folding endurance can be increased by 43.79%, 36.95%, 33.11%, 17.35%, 33.33% respectively, much better than the paper without the cationic hemicellulose. © (2011) Trans Tech Publications.

Abstract:Without using any surfactant or template, novel CuS three-dimensional (3D) structures consisting of nanosheets were successfully synthesized via a convenient one-step hydrothermal approach. X-ray diffraction pattern showed that the as-prepared product was pure hexagonal phase CuS. Scanning electron microscopy and high-resolution transmission electron microscopy images revealed that the as-prepared product comprised 3D microspheres (about 1-3 μm in diameter), which were further constructed with randomly oriented, single-crystalline CuS nanosheets (about 20 nm in thickness). The UV-vis absorption spectrum of the as-synthesized CuS 3D microspheres displayed an optical absorption minimum near 672 nm. Besides, the thermal stability of the as-synthesized CuS 3D microspheres was also studied. © 2011 Elsevier B.V. All rights reserved.

Abstract:Aiming at the hysteretic characteristics of classification problem existed in current internet traffic identification field, this paper investigates the traffic characteristic suitable for the on-line traffic classification, such as quality of service (QoS). By the theoretical analysis and the experimental observation, two characteristics (the ACK-Len ab and ACK-Len ba) were obtained. They are the data volume which first be sent by the communication parties continuously. For these two characteristics only depend on data's total length of the first few packets on the flow, network traffic can be classified in the early time when the flow arrived. The experiment based on decision tree C4.5 algorithm, with above 97 accuracy. The result indicated that the characteristics proposed can commendably reflect behavior patterns of the network application, although they are simple. © 2011 The Journal of China Universities of Posts and Telecommunications.

Abstract:MnxSr2-xBi4 Ti5O18 (A-SBTi-x, x=0-0.08) and Sr2Bi4Mny Ti5-yO18 (B-SBTi-y, y=0-0.08) ceramic samples were prepared using the solid-state reaction. Crystal structure, ferroelectric, dielectric and magnetic properties were investigated and compared. The X-ray diffraction results indicate the formation of single-phase material. Lattice constant a varies slightly for B-SBTi-y, while the lattice constant of A-SBTi-x vary dramatically. The lattice constant a of the A-SBTi-x decreases from 0.3868nm with x=0 to 0.3856nm at x=0.02, then increases with further Mn substitution and reaches 0.3870nm at x=0.08. Remnant polarization (2Pr) of A-SBTi-x and B-SBTi-y varies differently when x and y are quite low. As x and y values increase further, the changes of 2Pr are similar. Both A-SBTi-x and B-SBTi-y have a weak ferromagnetic nature at room temperature.

Abstract:The buckling and post-buckling behaviors of a functionally graded material (FGM) column under distributed load were analysed. Based on the large deformation theory and consideration of the axial extension of the column, the quilibrium equations with geometric nonlinearity of an elastic FGM column subjected to distributed load were established. In the analysis, it was assumed that the material properties of the column vary continuously as a power function of the thickness coordinate. By using shooting method and analytical continuation, the nonlinear boundary-value problem was solved numerically and buckling and post-buckling response of FGM column with free-fixed edges were obtained. The post-buckling characteristics curves of FGM column under the different graded index were plotted, which were compared with the those of pure metal and ceramic material columns. The effects of material gradient property on the buckling deformation and critical load of beam were discussed in details. The results show that the post-buckling behavior of the FGM column are different from that of homogenous column, and the gradient index of the material have significant effect on the bucking load and post-buckling behavior of the FGM columns.

Abstract:A three-dimensional numerical model is proposed for modeling the TP transport in the Horizontal Subsurface Flow (HSSF) and Wavy subsurface Flow (WSSF) constructed wetland in this article. Both numerical simulations and physical experiments indicate that the removal efficiency of WSSF is higher than that of HSSF. The difference of performance in removing pollutants, e.g., Total Phosphorus (TP), between HSSF and WSSF is numerically analyzed from three interactive aspects, that is, the hydraulic behavior, the substrate and the plant roots. It is shown that the dead zone volume in WSSF is smaller than in HSSF with less short circuiting. The soil in the top layer is more used in WSSF than in HSSF. The TP uptake by the plant roots in WSSF is higher than that in HSSF. © 2011 Publishing House for Journal of Hydrodynamics.

Abstract:Based on the von Karman plate theory of large deflection, we have derived a non-linear partial differential equation for the vibration of a thin orthotropic plate under the combined action of a transverse magnetic field and a transverse harmonic mechanical load. The influence of the magnetic field is due to the magnetic Lorentz force induced by the eddy current. By employing the BubnovGalerkin method, the non-linear partial differential equation is transformed into a third-order non-linear ordinary differential equation. The amplitude-frequency equations are further derived by means of the multiple-scale method. As numerical examples for an orthotropic plate made of silver, the influence of the magnetic field, orthotropic material property, plate thickness, and the mechanical load on the principal resonance behavior is investigated. The higher-order effect and stability of the solution are also discussed. © 2011 Elsevier Ltd. All rights reserved.

Abstract:By using the method of exact diagonalization, we investigate the quantum correlation measured by quantum discord of the dimerized spin chain at both zero and finite temperatures. The results disclose that the quantum discord is robust at any finite parameter α and temperature T, in contrast to entanglement which shows a sudden death when the parameter α or the temperature T reaches a critical point. At finite temperature, it is interesting to find that the quantum discord QD 2i-1, 2i can increase with temperature T no matter if the entanglement EoF 2i-1, 2i exists or not. The research on the relation between the quantum discord and the quantum phase transition in the dimerized spin chain indicates that the transition can be characterized by the first derivation of the quantum discord at zero and low temperatures. © 2011 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.

Abstract:A bending vibration model and a dynamic measuring model for a Half Coated Metal Core Piezoelectric Fiber (HMPF) were established. On the basis of the equivalent bending moment from an applying voltage, the bend vibration model of HMPF for a cantilever structure was deduced. According to the first piezoelectric equation, the surface electric displacements, electric charges and the admittances of the HMPF were derived when the resonant exciting voltage was applied. Then, the dynamic measuring model was established to measure the resonant frequencies, anti-resonant frequencies and the low frequency capacitances and to obtain the main parameters, elastic coefficients s11E, electromechanical coupling factors k31, dielectric constants Ε33T Tand piezoelectric coefficients d31. Three kinds of samples for HMPFs were measured, and their average values are elastic coefficient in 16.856 × 10-12 Pa-1, electromechanical coupling factor in 0.179, dielectric constant in 2251 and piezoelectric coefficient in -103.621 pC/N. The theoretical simulation and experimental results show that this method is accurate and available.

Abstract:This study proposed a two-region model (TRM) to describe reactive solute transport with scale-dependent dispersion in heterogeneous porous media. The model was derived from the conventional TRM but assumed the dispersivity to be a linear and exponential function of travel distance. The linear adsorption and first-order degradation of solute were also considered in the model. The Laplace transform technique and de Hoog numerical inversion method were applied to solve the developed model. The break-through curves (BTCs) obtained from TRM with scale-dependent and constant dispersion were compared, and the effective dispersivity for TRM with scale-dependent dispersion was calculated by averaging the distance-dependent dispersivity with arithmetic method. This effective dispersivity could reflect the accumulated scale-dependent dispersion effect over the entire travel domain, but discrepancy will occur if the dispersion effect is great. The applicability of the proposed model was tested with concentration data obtained from a 1250 cm long and highly heterogeneous soil column. The simulation results indicated that the TRM with constant and linear distance-dependent dispersivity were unable to describe the measured BTCs in the column adequately, while the TRM with exponential distance-dependent dispersivity satisfactorily captured the evolution of BTCs. Therefore, the proposed TRM with scale-dependent dispersion by assuming the dispersivity to be a function of distance is a simple and practical approach to describe solute transport at relatively large scale in heterogeneous porous media, but the increase of dispersivity with distance is limited as it has bounds.

Abstract:In this paper, Markov chains are used to model represents a user access problem in a relay cooperative network. In this system source users and relay users are in a opportunistic spectrum access scheme with spectrum handoff. The blocking, dropping, transition probabilities and channel utilization of this system are derived as the performance metrics. Simulate results show that though the channel utilization is certain lost, the blocking, dropping and transition probabilities are greatly reduced with the increasing number of relay channels. And blocking probability is minimum when λs << λr.

Abstract:Automatic text categorization is an important method on dealing with vast amounts of information. It has many mature algorithms, mainly based on statistical methods. However, traditional statistical models didn't reflect the relevance between the text, syntax and semantic information. In this paper, we research the text categorization process based on Hidden Markov Model (HMM). In the training process, we learn the parameters of HMM classifier. The output observation distribution combines 2 statistical and improved TFIDF method, to reflect the semantic relationship in the different categories. In the testing process, evaluate the performance of the established HMM classifier, using the evaluation criteria of Macro-average and Micro-average, and feed back the classifier to improve. In the category process, categorize the new document, using forward-backward algorithm to the HMM classifiers and obtaining the probabilities respectively, comparing them to get the category label with the max probability, which is the final result. The whole process reflects the semantic character in different documents, and improves the accuracy of text categorization by the relationship between text features and categories.

Abstract:The ZrW2O8 Films with a negative thermal expansion property were deposited by RF magnetron sputtering on Si substrates. The impacts of the deposition conditions, purity of target materials, annealing temperatures and sputtering power, on film quality were evaluated. The microstructures and mechanical properties of the films were characterized with X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy and conventional surface probes. The results show that the annealing temperature strongly affects the surface stress distribution of the fairly smooth, compact films with good negative thermal expansion. For example, annealed at 750°C for 3 min, bigger grains with increased pores were observed. The stress uniformly distributes with little variations in the as-deposited films. As the substrate and annealing temperatures increased, the stress, 1.613 GPa at least, its uniform stress distribution deteriorated with an increased bigger stress difference, possibly because of the mismatch of thermal expansion coefficients at the interface of the film and the substrate.

Abstract:A new water-soluble inclusion complex of ferrocene (Fc) with β-cyclodextrin polymer (β-CDP) was prepared by a facile strategy and characterized by 1H NMR spectroscopy, elemental analysis, powder X-ray diffractometry, thermogravimetry, UV-vis spectroscopy and cyclic voltammetry. Compared with Fc and the inclusion complex of Fc with β-cyclodextrin (Fc-β-CD), the solubility of ferrocene-β- cyclodextrin polymer (Fc-β-CDP) was greatly enhanced due to the water-soluble β-CDP host. The ratio of β-cyclodextrin (β-CD) unit in β-CDP to Fc was determined as 1:1. At 25 °C, the dissociated constant of Fc-β-CDP was measured as 3.65 mM by UV-vis spectroscopy and cyclic voltammetry. The electrochemical properties of Fc-β-CDP in water were studied. The diffusion coefficients of oxidation state and reduction state were calculated as 3.52 × 10-7 cm2 s-1 and 3.93 × 10-7 cm2 s-1. The resulting value of standard rate constant was measured as 1.95 × 10-3 cm s-1. The diffusion activation energy was calculated as 21.8 kJ mol-1. © 2011 Elsevier Ltd. All rights reserved.

Abstract:SnS2/SnO2 nanocomposites with tunable SnO2 contents were prepared via in situ hydrothermal oxidation of SnS2 nanoparticles in 0.375-4.5 mass% H2O2 aqueous solutions at 180 °C for 0-12 h. The structure, composition and optical properties of the as-prepared SnS2/SnO2 nanocomposites were characterized by X-ray diffraction, transmission electron microscopy, high-resolution transmission electron microscopy, Brunauer-Emmett-Teller (BET) surface area analysis, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, and UV-vis diffuse reflectance spectra. Furthermore, their photocatalytic properties were tested for the degradation of methyl orange in water under visible light (λ > 420 nm) irradiation. It was found that the as-prepared SnS2/SnO2 nanocomposites with suitable SnO2 content not only demonstrated superior photocatalytic activity to both SnS2 nanoparticles and physically mixed SnS 2/SnO2 composite nanoparticles, but also had remarkable photocatalytic stability. The tight attachment of SnO2 nanoparticles to SnS2 nanoparticles, which can facilitate interfacial electron transfer and reduce the self-agglomeration of two components, was considered to play an important role in achieving the high photocatalytic performances exhibited by the as-prepared SnS2/SnO2 nanocomposites. © 2011 American Chemical Society.

Abstract:Return-Oriented Programming (ROP) is a technique which leverages the instruction gadgets in existing libraries/executables to construct Turing complete programs. However, ROP attack is usually composed with gadgets which are ending in ret instruction without the corresponding call instruction. Based on this fact, several defense mechanisms have been proposed to detect the ROP malicious code. To circumvent these defenses, Return-Oriented Programming without returns has been proposed recently, which uses the gadgets ending in jmp instruction but with much diversity. In this paper, we propose an improved ROP techniques to construct the ROP shellcode without returns. Meanwhile we implement a tool to automatically construct the real-world Return-Oriented Programming without returns shell-code, which as demonstrated in our experiment can bypass most of the existing ROP defenses.

Abstract:Hollowing of inorganic nano/micromaterials can be realized by well-known Ostwald ripening and Kirkendall processes. However, hollowing of organic polymer without sacrificial templates is seldom seen. Herein, we demonstrate for the first time that conducting polymer nanofibers can be transformed into nanotubes by a simple, effective, and controllable swelling-evaporation strategy. By controlling swelling degree, surface-patterned poly(o-toluidine) (POT) nanofibers, and nanotubes with controllable inner diameter can be fabricated. Novel characteristics of such nanotubes, such as patterned surfaces and sealed tips, will endow them with enhanced properties when applied in fields as controlled drug delivery, noble metal nanocatalysts supporter, and adsorbent for heavy-metal ions.

Abstract:In order to supply better flow conditions for pump and improve pumping system efficiency, numerical simulations were conducted in this paper on 3 design schemes of a shaft tubular pumping system to compare their energy performances and investigate the relationship between the design scheme and the system characteristics. With the same design of suction box and discharge passage, the head losses of the outlet discharge passage and the pumping system efficiencies were compared between 2 design schemes of different size and shape of the shaft (pit). The flow conditions of pump, in terms of distribution uniformity of axial velocity and velocity-weighted bias angle of outflow field in the outlet cross-section of suction box, and the pumping system efficiencies were compared between the front and rear arrangement of the shaft while keeping the shaft and the pump unchanged. The computational results show that for the rear arrangement of shaft schemes the size and shape of the shaft affect not only the head loss of the discharge passage but also the pumping system efficiency. If just simply turning the pump around 180 degrees without changing pump and flow passages, the pumping system can be operated both in the rear arrangement scheme of shaft and front arrangement scheme. However, the flow conditions of pump become deteriorated in terms of distribution uniformity and bias angle when the rear arrangement scheme of shaft changed to front arrangement. As a result, the hydraulic losses of suction box and discharge passage in front arrangement increases, the best efficiency point drops and high efficiency zone moves toward smaller flow rates. © 2011 IEEE.

Abstract:There are many ways to improve flow conditions of pump, such as "ω" type rear wall, vertical columns and bottom sills as well as other engineering measures. They are widespread used and effective in regulating flow patterns and velocity distributions in forebay and sump, however, the difference affecting flow conditions of pump are never evaluated quantitatively before. In this paper, a series of specially designed "ω" type rear wall, vertical columns and bottom sills with different parameters are placed in different places of the sump in turn while keeping the water levels and pump discharge unchanged. A swirl meter is adopted to measure swirl intensities in the suction pipe of pump, and the effects of different intake design schemes and engineering measures on flow conditions of pump are compared quantitatively in terms of swirl angle. The experimental results show that under certain conditions vertical columns and bottom sills can improve flow conditions, but their design parameters and where they are placed in the sump need to be optimized in order to obtain better results. The "ω" type rear wall with bottom pilot cone can considerably reduce the intensity of swirl in the suction pipe of pump, the mechanism of which needs to be studied extensively. © 2011 IEEE.

Abstract:DC micro-grids is an advanced electric delivery infrastructure candidate for future Smart Grid. By interactively integrating a wide selection of renewable sources, energy storages as well as traditional utility grid within a local power network, DC micro-grids can achieve economical system operation, and bing local survivability to critical zones. As important supplement to conventional generation means, properly used renewable sources and energy storages can minimize the operational costs and maximize the system performance. Power converter system with multi-input and integrated structure is capable of processing and managing multiple sources and storages simultaneously, which is being considered as the prospective building blocks of future DC and AC micro-grids. This paper presents two new load sharing methods in dc-dc conversion for multiple inputs. First, a detailed survey will be conducted to show the status of load sharing methods in dc-dc power conversion; new requirements for load sharing operation in a DC micro-grid environment will be proposed; a cascade and a parallel organized load sharing control system proposed by the authors are presented and discussed for a multi-source/storage hybrid power system; both simulation and experimental results will be presented in the last section to prove the effectiveness of the new load sharing methods. © 2011 IEEE.

Abstract:A facile and friendly environmental route has been developed to prepare one-dimensional β-FeOOH nanorods without any template at low temperature. In the present reaction system, FeCl36H2O was used as a single iron precursor. Effects of different experimental conditions on morphology and polymorph of the as-prepared samples were studied. Compared with the urea, the concentration of FeCl3 influenced evidently the length of the as-formed β-FeOOH nanorods. The aspect ratio of the sample was adjusted from 6 to 24 by changing the concentration of FeCl3. When the experimental temperature increased from 70 to 80 °C, the morphology of the resulting β-FeOOH changed from spindle to rod. The influences of different kinds of electrolytes on the final products were also studied. The results demonstrated that different electrolytes (KCl, KSCN, NaNO3 and NH4Cl) can strongly influence the sizes and structures of the as-prepared samples. Compared with various surfactants, the anionic surfactant, sodium dodecyl sulfate (SDS), affected significantly the morphology and size of the as-prepared samples. Nanoribbon-shaped β-FeOOH was synthesized in the presence of SDS for the first time. © 2011 Elsevier B.V. All rights reserved.

Abstract:In the past decades, parallel manipulators have been found in many industrial applications and a number of interesting mechanical devices and design methods have been extensively studied. However, most efforts are dedicated to six degrees of freedom (DOF) or three-DOF manipulators. This paper presents a novel six-leg, four-DOF parallel platform manipulator with base mounted prismatic actuators. The movable platform of the manipulator can translate along two directions and rotate around two axes respectively (2T-2R). The kinematics model is formulated, which describes the inverse and forward kinematics transformation. The singularity analysis of this six-leg, four-DOF parallel manipulator is introduced. © 2010 IEEE.

Abstract:In order to acquire detail information of a regional winter wheat within growth season to instruct the production, the experiment was carried out in wheat growth season during 2007-2009 in Jiangsu province to monitor main growth parameters with Landsat TM data. The relationships of main growth parameters, grain quality and yield parameters at anthesis stage were analyzed, as well as the relationships of main growth parameters with satellite remote sensing variables. And then the quantitative relationship models were established and evaluated to monitor SPAD, biomass, leaf area index (LAI) and leaf nitrogen content(LNC) in winter wheat using remote sensing spectral variables derived from Landsat TM images. The results showed that at anthesis stage, it was feasible to monitor wheat SPAD, biomass, LAI and LNC using the satellite remote sensing variables of nitrogenous reflection index (NRI), B4 and normalized difference vegetation index (NDVI) respectively. Based on sensitive remote sensing variables, the models for monitoring SPAD, biomass, LAI and LNC at anthesis stage in winter wheat were established, which the root mean square error (RMSE) for SPAD, biomass, LAI and LNC were 3.12, 216.5 kg/hm2, 0.269 and 0.162, respectively. Based on the monitoring models, the thematic mapping of monitoring SPAD, biomass, LAI and LNC under different grades at anthesis stage can be got to realize the spatial quantization expression for monitoring main growth parameters. The technology to obtain large area information using satellite remote sensing data can overcome the shortcoming of point sampling technology, and provide timely informations for agricultural production management decisions.

Abstract:ZrW2O8 thin films were deposited on quartz substrates by pulsed laser deposition method. Effects of substrate temperature on the microstructure, composition, surface roughness and morphology of the ZrW2O8 thin films were observed by X-ray diffraction (XRD) and atomic force microscope (AFM). The thickness and optical transmittance of the ZrW2O8 thin films were measured by surface profilometer and spectrophotometer respectively. The negative thermal expansion property of the ZrW2O8 thin film was measured by high temperature X-ray diffraction. The results indicate that the as-deposited ZrW2O8 thin films deposited at the substrate temperature of room temperature, 550°C and 650°C are amorphous phase, and the cubic ZrW2O8 thin film can be obtained after annealing at 1200°C for 3 min and then quenching in water. With the increase of deposition temperature, the surface roughness decreases markedly. The optical transmittances of the ZrW2O8 thin films prepared at different condition are about 80%, and the negative thermal expansion coefficient of the resulting cubic ZrW2O8 thin film is -11.378×10-6 K-1 in the temperature range from 20°C to 600°C.

Abstract:In order to know the evaporating capacity of channel and lake reservoir water surface along Jiangsu section of the Eastern Route of South-to-North Water Diversion Project(JERP), its power loss of the pumping stations and its influence on water transfer efficiency of JERP, evaporating capacity calculating models and formulae which are suitable for the areas where JERP locates were analyzed and compared. Evaporating capacity of every channel and lake reservoir water surface along JERP was calculated by integral. Both spacial and temporal distribution characteristics of the evaporating capacities of water surface were analyzed. The discharge loss and input power loss of every step pumping stations caused by water surface evaporation were calculated. The effect of water surface evaporation on water transfer efficiency of JERP was computed and analyzed. The results show that the evaporating capacities of water surfaces gradually increase from south to north and north-west, and are largest in summer and least in winter. The annual average evaporating capacity of water surfaces amounts to 862.2 mm. The evaporation water volume losses of Hongze Lake, Luoma Lake, Baima Lake and water transfer channels are 77.7%, 13.3%, 3.6% and 5.4% of the total evaporation water volume loss respectively.17.46% of the water pumped by source pumping stations loses for evaporation, which causes water transfer efficiency of JERP to decrease by 10.33%, and that is a considerable energy loss. Pipelines could be considered for the great water transfer projects which could avoid evaporating capacity of water surface.

Abstract:The internal flow field in a vertical axial flow pumping system was simulated by CFX software using the Reynolds averaged N-S equations and RNG k-Ε turbulence model. Focusing on details of the inlet flow field, the flow characteristics in the inlet and outlet passages of pumping system were analyzed based on the calculation of different operating conditions with the flow rates range 180-340 L/s at the rated rotating speed. The results show that rotating of impeller has effects on the distribution of axial and tangential velocity components at the pump inlet, but the numerical values are relatively small. Outlet circulation of guide vane has great influence on flow pattern in the outlet passage. The flow distribution for both sides of the dividing pier is not symmetric, especially for small flow rate condition, the helical flow occurs at the right side of dividing pier. A good agreement is achieved in the performances of the pumping system between the predicted data and experimental data at the best efficiency point, which can meet the requirement of practical application.

Abstract:A new method for the determination of roxithromycin based on the fluorescence quenching of 3-mercaptopropionic acid-capped CdTe quantum dots (MPA-CdTe QDs) was developed. In ethanol medium, the fluorescence of CdTe quantum dots at 552 nm was quenched in the presence of roxithromycin. Based on this a simple, sensitive, and selective method for rapid determination of roxithromycin was described. Reaction time, interfering substances on the fluorescence quenching, and mechanism of the interaction of CdTe QDs with roxithromycin were investigated. After optimization, the proposed method allows the determination of roxithromycin over the range 25.0350.0 μg ml -1. The detection limit is 4.6 μg ml-1. The proposed method was successfully applied to commercial capsules and tablets with satisfactory results. The recovery of the method was in the range of 96.8102.5%. © 2010 Elsevier B.V.

Abstract:For the shortcoming of the SVM using in short series of power load forecasting, namely the choice of space divided parameters is influenced by subjective factors, a novel method of power load forecasting combining the spectrum analysis with LS-SVM method is presented. This method adopts the spectrum analysis to forecast the cycle of actual maximum power load and determines the training mode of SVM based on the cycle. The subjective factors in preferences are effectively avoided, and the prediction accuracy is improved. The practical example shows that except the last point in which the relative error is 8.67%, the relative errors of other points are less than ± 5%. Our method provides a better fit to the predicted data and shows high accuracy.

Abstract:Taking No.4 Jiangdu Pumping Station as a study case, which is one of the source stations in Eastern Route of South-to-North Water Diversion Project in China, the optimal operation of single pumping station for multiple pump units with variable speed was studied. The non-linear model of optimal daily operation for multiple pump units with variable speed was constructed with consideration of peak-valley electricity price and tides variation. Keeping the blade angle of pump unit at designed value, this model took the minimal electricity cost of multiple pump units as objective function, the time period as stage variable, the pump speed and quantity of operation units as decision variables, and the quantity of daily water pumped as constrain condition. The method which took the pump speed for experimental optimization, the quantity of operation units for linear integer programming was proposed to solve the model. The optimization results showed that under the average daily head of 7.8-3.8m, considering peak-valley electricity price and with 100% loads, the cost saving of water pumping per unit was -3.58%~-2.14% compared with operation in rating state, which showed that the optimization effect could not counteract the energy loss carried out by frequency converter. While under 80% and 60% loads, the optimization effect was obvious and the cost saving was 11.38%-15.71% and 24.79%-29.17% respectively. Under the average daily head of 7.8~3.8m, without considering peak-valley electricity price, the optimal operation had some benefits only under the low heads and with small operation loads(such as 5.8 m and 60% loads; 4.8 m and 80% loads; 3.8 m and 60% loads). While under the other heads and loads, the optimization effect could not counteract the energy loss carried out by frequency converter. The results can provide a new way for optimal operation of large-scale pumping station influenced by tides for multiple pump units with variable speed.

Abstract:Shot peening can improve fatigue strength of materials by creating compressive residual stress field in their surface layers, and offers a protection against crack initiation and propagation, corrosion, etc. And fatigue fracture and stress corrosion cracking of NAK80 steel parts are improved effectively. Currently there lacks in-depth research in which the beneficial effect of the residual stress may be offset by the surface damage associated with shot peening, especially in terms of the research on the effective control of shot peening intensity. In order to obtain the surface residual stress field of NAK80 steel after shot peening, the samples are shot peened by pneumatic shot peening machine with different rules. The residual stress in the precipitation-hardening layer of NAK80 steel is measured before and after a shot peening treatment by X-ray diffraction method. In order to obtain true residual stress field, integral compensation method is used to correct results. By setting up analytical model of the residual stress in the process of shot peening, the surface residual stress is calculated after shot peening, and mentioning the reason of errors occurred between calculated and experimental residual stresses, which is mainly caused by the measurement error of the shoot arc height. At the same time, micro hardness, microstructure and roughness in the precipitation-hardening layer of NAK80 steel before and after shot peening were measured and surveyed in order to obtain the relation between shot peening strength and surface quality in the precipitation-hardening layer. The results show that the surface quality of NAK80 steel is significantly improved by shot peening process. The over peening effect is produced when the shot peening intensity is too high, it is disadvantageous to improve sample's surface integrity, and leading to reduce the fatigue life. When arc high value of optimal shot peening is 0.40 mm, the surface quality is the best, and the depth of residual stress in the precipitation-hardening layer reaches to about 450 μm. Numerical calculation is very useful to define the process parameters when a specific residual stress profile is intended, either to quantify the benefits on a specific property like fatigue life or to help on modeling a forming process like shot peen forming. In particular, the proposed parameter optimization in the progress of shot peening and effective control of the surface texture provide new rules for the quantitative evaluations of shot peening surface modification of NAK80 steel.

Abstract:The influence of reducing nD value on hydraulic performance of a large pump system with low head was discussed from the point of view of pump type selection, energy performance and cavitation performance, and the design idea of reducing nD value for the pump system was put forward. The consistent relationship between reducing nD value and increasing impeller diameter and reducing pump speed was derived according to the affinity law of pumps. If the pump diameter increases by 5% under the condition of a certain design discharge, the pump speed and nD value will decrease by 13.6% and 9.3%, respectively. The effect of reducing nD value on increasing pump system efficiency was analyzed from the point of view of influence of impeller diameter on the conduit hydraulic loss. Based on the relation between nD value and pump head, it was put forward to reduce nD value for selecting the more excellent axial pump hydraulic model under the condition of low head. According to the cavitation affinity law of pumps, the influence of reducing nD value on the cavitation performance of the pump system was analyzed. Meanwhile examination index for the cavitation performance of the pump system and the influence of increasing impeller diameter and reducing pump speed on the conduit control sizes and equipment investment were also discussed. The research results indicate that if the pump diameter increases from 2.9 m to 3.1 m for a pump system with the average head of 4 m and single pump design discharge of 33.5 m3/s the conduit efficiency will increase by 2.9%. If the nD value decreases from 435 to 387.5 under the condition of a certain design discharge, the pump head at the high efficiency zone of the hydraulic model TJ04-ZL-06 will lower from 5 m to 4 m and the pump NPSHR will reduce by 20.6%. It suggests that a lower nD value should be adopted for a large pumping station with low head and long running operation time.

Abstract:Fusarium head blight (FHB) of wheat causes not only significant reduction in grain yield and end-use quality, but also the contamination of the grain with mycotoxins that are detrimental to human and animal health after consumption of infected grain. Growing resistant varieties is an effective approach to minimize the FHB damage. The Chinese wheat landrace Haiyanzhong (HYZ) shows a high level of resistance to FHB. To identify quantitative trait loci (QTL) that contribute to FHB resistance in HYZ, 136 recombinant inbred lines (RIL) were developed from a cross of HYZ and Wheaton, a hard spring wheat cultivar from the USA. The RIL and their parents were evaluated for percentage of scabbed spikelets (PSS) in both greenhouse and field environments. Five QTL were detected for FHB resistance in HYZ with one major QTL on 7DL. The 7DL QTL peaked at SSR marker Xwmc121, which is flanked by the SSR markers Xcfd46 and Xwmc702. This QTL explained 20.4-22.6% of the phenotypic variance in individual greenhouse experiments and 15.9% in a field experiment. Four other minor QTL on 6BS (two QTL), 5AS and 1AS each explained less than 10% of the phenotypic variance in individual experiments. HYZ carried the favorable alleles associated with FHB resistance at the QTL on 7DL, 6BS and 5AS, and the unfavorable allele at the QTL on 1AS. The major QTL on 7D can be used to improve the FHB resistance in wheat breeding programs and add diversity to the FHB resistance gene pool. © 2011 Springer-Verlag.

Abstract:Calix[8]arene ketone derivative was prepared by using electrophilic reagent chloroacetone and p-tert-butyl phenol through etectrophilic substitution reaction. And then the solid complexes of calix[8]arene ketone derivative with Praseodymium or Europium were further synthesized. Elemental analysis, infrared spectra, 13CNMR, XRD and thermal spectra were used to characterize the products. The results show that two kinds of the solid complexes are mononuclear molecules, central rare earth metal ions are coordinated by six oxygen atoms from two calix[8]arene ketone derivative and three nitrogen atoms from three N, N-Dimethylformamide molecules, leading to formation of nine-coordinated solid complexes with symmetrical tricapped trigonal prism structure.

Abstract:In the global competition, companies are propelled by an immense pressure to innovate. The trend to produce more new knowledge-intensive products or services and the rapid progress of information technologies arouse huge interest on knowledge management for innovation. However the strategy of knowledge management is not widely adopted for innovation in industries due to a lack of an effective approach of their integration. This study aims to help the designers to innovate more efficiently based on an integrated approach of knowledge management. Based on this integrated approach, a prototype of distributed knowledge management system for innovation is developed. An industrial application is presented and its initial results indicate the applicability of the approach and the prototype in practice. © 2011 Elsevier B.V. All rights reserved.

Abstract:Considering different condition adjustment, two stages decomposition-dynamic programming aggregation method was introduced to solve the mathematical model of daily optimal operation for parallel pumping stations which took the minimal daily electric cost of parallel pumping stations as objective function, the flow or speed of each unit as decision variable. Taking minimal daily electric cost of single pump station as objective function, allocation of water quantity pumped by each station as coordinated variable, this model was decomposed into several first stage sub-model of daily optimal operation for single pump station. Then taking minimal daily electric cost of single pump unit as objective function, allocation of water quantity pumped by each unit as coordinated variable, the first stage sub-model was decomposed into several second stage sub-model of daily optimal operation for single pump unit which takes the blade angle or unit speed as decision variable, the discrete value of water quantity pumped by each unit as state variable, and was solved by means of dynamic programming method. The constructed aggregation model took daily water quantity pumped by each pump unit as decision variable, the discrete value of water quantity pumped by parallel station group as state variable, and was also solved by dynamic programming method. This method could solve the optimal operation issues for parallel pumping stations with various operation modes, time period divisions and daily average heads of each station, and also provide theoretical support for the study on optimal operation of multi-stage pumping stations. Taking No.1, 3 Huaiyin pumping station as a study case, a series of optimization calculations were carried out. The results showed that the unit cost of optimal operation under 100%, 80%, and 60% loads within all average daily heads had an average energy consumption saving of 10.53%, 26.54% and 34.40%, respectively, compared with the operation with fixed blade angle and constant speed.

Abstract:In order to obtain tensile stress-strain curve and formula of rising part for concrete after freeze-thaw cycles, samples with four strength grades were subjected to uniaxial tensile experiment after 0, 25, 75, 100 or 125 freeze-thaw cycle times. Based on normal tensile stress-strain relationship, tensile stress-strain constitutive relationship of concrete after freeze-thaw cycles was proposed. The results show that the slope of the rising part of tensile stress-strain curve falls down gradually and the peaks of tensile stress and strain decrease linearly as cycle times of freeze-thaw increase. Samples with high strength grade express less decrease of peak tensile stress and strain than those with low strength grade for the same freeze-thaw cycles, while decreasing rate has slight difference.

Abstract:To realize adjusting the fire intensity of cooking robot continuously, a numerical calculation and experiments of dual-pressure fire system for blast gas combustor were carried out. Firstly, the basic equations of fluid mechanics, the equations of component transport and the equations of turbulence for the induction tunnel of combustor were established. Secondly, the CFD software FLUENT was utilized to build the two dimensional axisymmetry gas-kinetic model for the induction tunnel, to define the boundary condition, the initial state and the finite-rate chemical reaction model. Thirdly, the control method of dual-pressure fire intensity was obtained. According to the variation curve of pressure value of high-pressure air in the nozzle central axle with the accelerating value of combustible gas and quantity of air imbibed by ejection, the optimal matched pressure value of high-pressure air based on the specific heat load of combustible gas was obtained. The method was used on the cooking robot, which showed that the fire intensity feedback control could be achieved precisely and the power of common pressure (2.0 kPa) combustible gas combustor could be up to 18 kW.

Abstract:Using WO3/ZrO2 solid superacid as catalyst, the performance of H2O2/WO3/ZrO2 system on the catalytic oxidative deep desulfurization of diesel were studied. The technical parameters, such as the amount of oxidant, the dosage of catalyst, the reaction temperature and the reaction time were investigated. Furthermore, the power ultrasound was introduced to enhance the process. The effects of ultrasonic frequency, intensity and time on the desulfurization were investigated. The experiment results revealed that under the optimum oxidative desulfurization conditions of oxidation temperature 60°C, reaction time 90 min, the oxidant dosage V(H2O2):V(diesel)= 1:10 and the catalyst dosage 15 g/L diesel, after extraction of oxidized diesel the removal efficiency of sulfur compounds was up to 91.0%. The oxidation time with ultrasound were shortened to 40 min and the removal efficiency of sulfur compounds was increased to 95.6%.

Abstract:A newly developed technique for determining the angle of attack (AOA) on a rotating blade is used to extract AOAs and airfoil data from measurements obtained during the MEXICO (Model rotor EXperiments in COntrolled conditions) rotor experiment. Detailed surface pressure and Particle Image Velocimetry (PIV) flow fields at different rotor azimuth positions are examined for determining sectional airfoil data. The AOA is derived locally by determining the local circulation on the blade from pressure data and subtracting the induction of the bound circulation from the local velocity. The derived airfoil data are compared to 2D data from wind tunnel experiments and XFOIL computations. The comparison suggests that the rotor is subject to severe 3D effects originating from the geometry of the rotor, and explains why the Blade Element Momentum technique with 2D airfoil data over-predicts the loading of the rotor. The extraction technique is verified by employing the derived airfoil characteristics as input to computations using the BEM technique and comparing the calculated axial and tangential forces to the measured data. The comparison also demonstrates that the used technique of determining the AOA is a reliable tool to extract airfoil data from experimental data. © 2010 John Wiley & Sons, Ltd.

Abstract:In order to completely measure the complexity of the spatial layout and orderliness of urban intersections, a complexity degree model was developed from macro and micro perspectives. Conflict point and conflict probability were selected as the two key factors, one of which was analyzed using the diagram method and photogrammetry principle, and the other determined by using statistical analysis and curve fitting. The complexity degree values of intersections of different spatial layout under various traffic demands were calculated. The results indicate that the complexity degree values of intersections of the same type increase with volume and those of intersections of different types increase with the number of lanes. Complexity degree is a comprehensive quantitative index showing the working condition of intersections, and can be applied to planning urban road networks and safety appraisal of intersections.

Abstract:The individual compounds in an emulsion of tartaric acid stabilized by a commercial surfactant, Laureth 4, were brought into contact in order to estimate the deviation from equilibrium conditions during emulsion evaporation. The transfer of compounds between the phases was followed by visual observation of new phases appearing and the movement of the interfaces with time. The results revealed that, conversely to the equilibrium processes in the corresponding salicylate emulsions, in the present system the dissolution of the acid was faster than the formation of birefringent structures and the variation of different colloidal structures could be followed in the experiment. A suitable choice of initial ratio between the three compounds enabled the transfer of compounds to result in an early depletion of the solid acid and subsequently information could be obtained about the relation between the transport of surfactant and water-acid solution into the birefringent layer. A significant dependence was found between the composition of the entrants into the layer and the amount of surfactant liquid remaining. © Taylor & Francis Group, LLC.

Abstract:The electrocatalytic oxidative polymerization of o-phenylenediamine (o-PD) was performed on a reduced graphene oxide (RGO)/glassy carbon (GC) electrode. The electrolysis of o-PD was carried out using cyclic voltammetry and potentiostatic and galvanostatic methods. The experimental results demonstrated that the reduced graphene oxide (RGO) has a pronounced catalytic ability for the electrochemical oxidative polymerization of o-PD in a 0.60 M H 2SO4 solution compared to the bare GC electrode; however, graphene oxide has only a slight catalytic ability for the electrochemical oxidative polymerization of o-PD. The above three electrochemical techniques confirmed that there is a considerable discrepancy between the characteristics of the electrocatalytic oxidation of a species and the characteristics of the electrocatalytic oxidative polymerization of o-PD. This effect occurs because the charges passed during the electrolysis of o-PD on the bare GC electrode were mainly consumed for the formation of the soluble oligomer; however, RGO plays an important role in suppressing the formation of the soluble oligomer. An unexpected result was obtained: two or three pairs of the redox peaks of poly(o-phenylenediamine) (PoPD), synthesized using RGO as a catalyst, occur on the cyclic voltammogram in a wider potential range, depending on the polymerization conditions; however, only one pair of redox peaks occurs on the cyclic voltammogram of the conventional PoPD in a narrow potential range under exactly the same experimental conditions. The NMR and ESR spectra of the PoPD polymerized on the RGO/GC electrode are presented in this paper. © 2011 Elsevier Ltd. All rights reserved.

Abstract:Avalanche or cascade failure is ubiquitous. We first classify the cascading phenomena into two categories: the cascading disasters which result in large-scale functional failures and the cascading events that do not lead to disasters. We elucidate that two important factors, the increasing amount of events and the acceleration of event frequency, can induce the crossover from the cascading phenomenon to the cascading disaster. Through a simplified sandpile model and a heuristic logistic map, we demonstrate that the dependence of the event number on the observation time behaves as a power-law and as an exponential for these two different cascading events, respectively. The analytic derivations are found to be consistent with several empirical observations. Our present findings contribute to the understanding of the transition between different cascading events, providing a basis for the further understanding of the transitions among more general critical events. © 2011 Elsevier B.V.

Abstract:Two kinds of different-shaped poly(o-phenylenediamine) (PoPD) polymers: solid and hollow sub-microspheres with both size of about 700nm synthesized by a solution route without any additional directing agents, were employed as efficient adsorbents for removal of Pb(I{cyrillic, ukrainian}I{cyrillic, ukrainian}) ions from water. Firstly, chemical structures of PoPD sub-microspheres were performed by Fourier-transform infrared (FT-IR), UV-vis, 1H NMR spectra, X-ray diffraction (XRD) and GPC analysis. When used as adsorbents, both PoPD hollow and solid sub-microspheres showed high adsorptivity and adsorption capacity towards Pb(I{cyrillic, ukrainian}I{cyrillic, ukrainian}) ions in water, and mechanisms of adsorption behaviors were revealed by XRD and X-ray photoelectron spectra (XPS). It was found that the pH and concentration of Pb(I{cyrillic, ukrainian}I{cyrillic, ukrainian}) ion solution, as well as contact time and adsorbent dosage affect the degree of adsorption. Adsorption isotherms and kinetics of Pb(I{cyrillic, ukrainian}I{cyrillic, ukrainian}) ions onto PoPD sub-microspheres were also investigated according to experimental data. Comparative investigations of adsorption behaviors revealed that hollow sub-microspheres showed enhanced adsorptivity adsorption capacity towards Pb(I{cyrillic, ukrainian}I{cyrillic, ukrainian}) ions as compared with solid sub-microspheres typical at low adsorbent dosage. PoPD hollow sub-microspheres also showed good adsorptivity for other heavy-metal ions, such as Hg(I{cyrillic, ukrainian}I{cyrillic, ukrainian}), Cd(I{cyrillic, ukrainian}I{cyrillic, ukrainian}) and Cu(I{cyrillic, ukrainian}I{cyrillic, ukrainian}), which implied their potential applications as effective adsorbents for heavy-metal ions in water. © 2011 Elsevier Inc.

Abstract:An alternative two-step method has been proposed for the synthesis of Bi2O3 nanowires with a diameter of about 40 nm from common and cost-effective Bi(NO3)3•5H2O, Na 2SO4, and NaOH. That is, first, Bi2O(OH)SO 4 nanowires were prepared through the precipitation reaction of Bi(NO3)3•5H2O and Na2SO 4 in distilled water under the ambient condition and second, monoclinic phase Bi2O3 nanowires were prepared via the hydrothermal reaction of Bi2O(OH)SO4 and NaOH at 120 °C for 12 h. The resultant products were characterized by X-ray diffraction, field emission scanning electron microscope, and high resolution transmission electron microscopy. In addition, the photocatalytic studies indicated that the as-synthesized Bi2O3 nanowires were a kind of promising photocatalyst in remediation of water polluted by some chemically stable azo dyes. © 2011 Elsevier B.V.

Abstract:Most of the existing algorithms for mining frequent patterns could produce lots of projected databases and short patterns which could increase the time and memory cost of mining. In order to overcome such shortcoming, a fast and efficient algorithm named FBPM for mining frequent patterns in biological sequence is proposed. We first present the concept of primary pattern, and then use prefix tree for mining frequent primary patterns. A pattern growth approach is also presented to mine all the frequent patterns without producing large amount of irrelevant patterns. Our experimental results show that FBPM not only improves the performance but also achieves effective mining results. © 2011 IEEE.

Abstract:The paper is concerned with the controllability of impulsive functional differential equations with nonlocal conditions. Using the measure of noncompactness and Mo¨nch fixed-point theorem, we establish some sufficient conditions for controllability. Firstly, we require the equicontinuity of evolution system, and next we only suppose that the evolution system is strongly continuous. Since we do not assume that the evolution system generates a compact semigroup, our theorems extend some analogous results of (impulsive) control systems. © 2011 Elsevier Inc. All rights reserved.

Abstract:A straightforward and economically viable approach was developed to biomimetic synthesis of gold nanocrystals by using casein micelles (CMs) without additional reductant. The UV-vis, TEM, SAED, FTIR, DLS and XRD techniques were employed to systematically characterize Au nanocrystals synthesized. Isotropic gold nanoparticle (GNP) and gold nanoplates in good yields (up to 90%) with different sizes can be obtained easily by adjusting the experimental condition. Spherical nanoparticles were obtained with tunable mean sizes at higher pH and casein concentrations. The high colloidal stability of the spherical GNP is attributed to the formation of CM/GNP hybrid under some experimental condition. At lower pH, reaction temperature and casein concentrations, single-crystalline gold nanoplates in good yields (up to 90%) are obtained. The growth of these nanostructures is attributed to an interplay between the faceting tendency of the protein molecules/micelles and the growth kinetics. More importantly, the morphological evolution of large gold nanoplates at different reaction times has been followed, and compared with some earlier protein systems, different formation mechanisms in casein micelles are obtained. The results demonstrate that both the property of individual protein molecules and protein aggregates play important roles in controlling the formation of gold nanocrystals by using amphiphilic protein. © 2010 Elsevier B.V.

Abstract:An n-butanol-based nanofluid containing nanowire-shaped β-FeOOH was synthesized by a solvothermal method. The nanofluid was stable for 7 days without any precipitation with 3.0 mM SDBS as stabilizer. Uniform β-FeOOH nanowires with high aspect ratios were fabricated. The heat capacities of the obtained β-FeOOH sample, the base fluid, and the nanofluid were determined by an adiabatic calorimeter. Smoothed heat capacities and thermodynamic functions of the obtained samples, such as H(T/K) - H(298.15 K) and S(T/K) - S(298.15 K), were calculated based on the fitted polynomials and the relationships of the thermodynamic functions. These results are very useful to apply to the as-produced nanowire-shaped β-FeOOH and the nanofluid in engineering fields. © 2010 American Chemical Society.

Abstract:Background: Human insulin-like growth factor-I (hIGF-I) is a growth factor which is highly resemble to insulin. It is essential for cell proliferation and has been proposed for treatment of various endocrine-associated diseases including growth hormone insensitivity syndrome and diabetes mellitus. In the present study, an efficient plant expression system was developed to produce biologically active recombinant hIGF-I (rhIGF-I) in transgenic rice grains.Results: The plant-codon-optimized hIGF-I was introduced into rice via Agrobacterium-mediated transformation. To enhance the stability and yield of rhIGF-I, the endoplasmic reticulum-retention signal and glutelin signal peptide were used to deliver rhIGF-I to endoplasmic reticulum for stable accumulation. We found that only glutelin signal peptide could lead to successful expression of hIGF-I and one gram of hIGF-I rice grain possessed the maximum activity level equivalent to 3.2 micro molar of commercial rhIGF-I. In vitro functional analysis showed that the rice-derived rhIGF-I was effective in inducing membrane ruffling and glucose uptake on rat skeletal muscle cells. Oral meal test with rice-containing rhIGF-I acutely reduced blood glucose levels in streptozotocin-induced and Zucker diabetic rats, whereas it had no effect in normal rats.Conclusion: Our findings provided an alternative expression system to produce large quantities of biologically active rhIGF-I. The provision of large quantity of recombinant proteins will promote further research on the therapeutic potential of rhIGF-I. © 2011 Cheung et al; licensee BioMed Central Ltd.

Abstract:The metal core piezoelectric fiber (MPF) is one of the new type piezoelectric devices for sensors and actuators. To investigate the dynamic characteristics of a cantilever MPF, the dynamic admittance matrix is established. It can describe the response of a cantilever MPF subjected to driving parameters, a harmonically varying axial force F at the tip and a harmonically varying voltage V on the electrodes. The responses parameters of a cantilever MPF, including a dynamic tip elongation δ and a dynamic electric charge Q, can be obtained using the vibration theory and the average distributed electrical charge method. The response parameters are related to the driving parameters by a 2 × 2 matrix. The dynamic models for measuring piezoelectric parameters of a MPF are given in order to illustrate the applications of the previous dynamic admittance matrix. The piezoelectric parameters, the elastic coefficient s11E , the piezoelectric coefficient d31 and the dielectric constant Ε33T of MPF were measured experimentally. © 2011 - IOS Press and the authors.

Abstract:Dislocations and the elastic fields they induce in anisotropic elastic crystals are basic for understanding and modeling the mechanical properties of crystalline solids. Unlike previous solutions that provide the strain and/or stress fields induced by dislocation loops, in this paper, we develop, for the first time, an approach to solve the more fundamental problem - the anisotropic elastic dislocation displacement field. By applying the point-force Greens function for a three-dimensional anisotropic elastic material, the elastic displacement induced by a dislocation of polygonal shape is derived in terms of a simple line integral. It is shown that the singularities in the integrand of this integral are all removable. The proposed expression is applied to calculate the elastic displacements of dislocations of two different fundamental shapes, i.e. triangular and hexagonal. The results show that the displacement jump across the dislocation loop surface exactly equals the assigned Burgers vector, demonstrating that the proposed approach is accurate. The dislocation-induced displacement contours are also presented, which could be used as benchmarks for future numerical studies. © 2011 Elsevier Ltd. All rights reserved.

A memoryless state feedback dissipative controller is developed based on Lyapunov-Krasovskii functional approach such that the closed-loop system is robustly stochastically stable and weakly delay-dependent (RSSWDD) and strictly (Q, S, R)-dissipative. The sufficient condition on the existence of state feedback dissipative controller is presented by linear matrix inequality (LMI). And the desired controller can be concluded as solving a set of LMI. Finally, a numerical example is provided to demonstrate the effectiveness of the proposed approach.

Abstract:Post-buckling behavior of elastic beams with immovable ends and a point space-constraint under hygrothrrmal loadings were studied. Based on the geometrically nonlinear theory and linear hygrathermal strain-temperature and humidity relation for the axial extensional Euler-Bernoulli beams, governing equations for large post-buckling deformation of the elastic beams with a point space-constraint and subjected to temperature and humidity rising were formulated, in which seven basic unknown functions, such as the arc length of the deformed axial line, the line displacement components, the rotational angle of the cross-section, the internal resultant forces and moment, were included. It is assumed that the point-space constraint be around the middle point of the beam and the space value be in the range of hygrothermal post-buckling deformation. Boundary conditions at the two ends of the beam were considered to be immovably simply supported (pinned-pinned) and fixed (fixed-fixed), respectively. By using shooting method to solve the above mentioned strong nonlinear two-point boundary value problem numerically, hygrothermal post-buckling response of the beam under uniform increment both in temperature and humidity were obtained. Especially, changes in the characteristics of the hygrothermal post-buckling deformation and the internal forces of the beam after its middle point deflection reaches the gap value and at the same time the constraint force arises. Curves of equilibrium paths and configurations of the beams depending on the middle point space-constraint force were presented.

Abstract:Based on the traditional PI control strategy and LMI algorithms, a new controller design scheme is proposed for stochastic Markov jump systems with a time-varying delay and an unknown nonlinear function. Stochastic stability, tracking performance and robust performance are realized in the multi-objective scheme. By using the Lyapunov stability theory and the peak-to-peak measure, we construct the PI tracking controller to guarantee the stochastic stability and the tracking performance of the stochastic systems, optimize the tracking performance, enhance the ability of the disturbance attenuation and improve the robustness of the stochastic systems. Finally, a numerical example is included to show that the proposed method is feasible.

Abstract:ZnS Nanostructures, including nanoparticles and nanospheres, were synthesized through solvothermal process. The size and crystallinity of the ZnS nanostructures were easily controlled by the precursor source and the solvents. The photoluminescence (PL) in the range of 400-650 nm has been observed and the broad band is peaked at about 525 nm. The PL intensity reduced greatly with increasing the nanoparticle size of the as-prepared samples and the ratio of zinc and sulfur sources in the preparation process. Spectral examinations and analyses reveal that the 525 nm emission peak indeed originates from the electronic states determined by the zinc vacancies. © 2010 Springer Science+Business Media, LLC.

Abstract:By analyzing the direction characteristic of principal component analysis (PCA), we propose an edge detection method based on PCA. Using Karhunen-Loe¨ve transform, PCA transforms the original dataset into lower-dimensional feature data. The transform has directivity both on energy accumulation and data selection. The author points out and proves the two direction characteristics. In this paper, authors proposed a method of edge detection based on PCA. Authors used twice PCA operations, called TPCA, first by process the image by PCA and second by process the transpose of the image by PCA. Experimental results are shown by using some typical images.

Abstract:Nonlinear classification has been a non-trivial task in machine learning for the past decades. In recent years, kernel machines have successfully generalized the inner-product based linear classifiers to nonlinear ones by transforming data into some high or infinite dimensional feature space. However, due to their implicit space transformation and unobservable latent feature space, it is hard to have an intuitive understanding of their working mechanism. In this paper, we propose a comprehensible framework for nonlinear classifier design, called Manifold Mapping Machine (M3). M3 can generalize any linear classifier to nonlinear by transforming data into some low-dimensional feature space explicitly. To demonstrate the effectiveness of M3 framework, we further present an algorithmic implementation of M3 named Supervised Spectral Space Classifier (S3C). Compared with the kernel classifiers, S3C can achieve similar or even better data separation by mapping data into the low-dimensional spectral space, allowing both of its mapped data and new feature space to be examined directly. Moreover, with the discriminative information integrated into the spectral space transformation, the classification performance of S3C is more robust than that of the kernel classifiers. Experimental results show that S3C is superior to other state-of-the-art nonlinear classifiers on both synthetic and real-world data sets. © 2011 Elsevier B.V.

Abstract:Poly(4-oxybenzoyl) (POB) based composite films were sintered on test blocks, while POB was synthesised in situ by melt polycondensation. The XRD analysis corroborates a high degree of crystallinity of the obtained POB. However, the obtained POB exhibited a lower decomposition temperature T d and a lower crystal transition temperature Tc than the commercial POB. Sand blasting of the substrates' surfaces led to a substantial increase in the bonding strength between the prepared composite coatings and the substrates. Nevertheless, increasing the coating's thickness, increasing the MoS2 mass content in a coating or elevating the sintering temperatures resulted in a decrease in bonding. The fracture modes of the coatings during the peel tests were depicted as a combination of the separation of the coatings from the substrates and the breaking of the coatings themselves when the coatings' thicknesses ranged from 50 to 200 μm. © 2011.

Abstract:A new optimization scheme of loading paths for tube hydroforming (THF), which integrates dynamic explicit FEA code LS-DYNA with elitist non-dominated sorting genetic algorithm (NSGA-II), is proposed and applied to the loading path optimization for the hydroforming of an instrument panel beam. The results show that by using the scheme proposed, good results are achieved, and in addition, several Pareto solutions can be obtained in one operation, so providing more choices for the determination of loading paths in THF.

Abstract:Hydraulic performances of slanting inlet conduits of three pump shaft angles(15, 30 and 45) were studied by numerical computation of 3-D turbulent flow. Model experiments for the same conduits were also conducted. The results reveal that all the flows in the conduits are smooth and uniform and that hydraulic performances are excellent with small hydraulic losses. All the conduit designs can provide the pump impeller with good inflow conditions. As the angle decreases, the objective function defined by the conduit's outflow parameters increases, and the conduit loss decreases, while the hydraulic performance changes little. © Copyright.

Abstract:This paper is concerned with a double fronts free boundary problem for the heat equation with a localized nonlinear reaction term. The local existence and uniqueness of the solution are given by applying the contraction mapping theorem. Then we present some conditions so that the solution blows up in finite time. Finally, the long-time behavior of the global solution is discussed. We show that the solution is global and fast if the initial data is small and that a global slow solution is possible when the initial data is suitably large. © 2011 Elsevier Ltd.

Abstract:The present paper attempts the quantitative determination of the polymerisation degree and mass fraction of polyoxybenzoate in the polyoxybenzoate based composite coatings sintered on 1045 steel test blocks. The determinations were carried out successfully via the analysis of p-hydroxybenzoic acid hydrolysed from polyoxybenzoate in a KOH solution by use of high performance liquid chromatography. The polymerisation degree of polyoxybenzoate increased with the reaction time and temperature, in particular when catalysed. The maximum polymerisation degree was 27-6 under the optimised conditions. The determined mass fraction of polyoxybenzoate in composite coatings deviated greater than 10% from the theoretical values either blocked or not. This is possibly due to the incomplete inhibition of the sublimation of p-acetoxybenzoic acid, the precursor of polyoxybenzoate, during the fabrication of polyoxybenzo-ate based composite material. © Institute of Materials, Minerals and Mining 2011.

Abstract:To investigate the ways of maintaining high and stable crop yield under long-term fertilization, a long-term field experiment was set up in 1980 in a typical rice-wheat rotation region-the Taihu Lake Region. The changes of rice and wheat yield and soil nutrient under term fertilization in different years, the crop yield stability and the relationship between crop yield and soil organic carbon and nitrogen were analyzed. Results showed that during the period of long-term experiment, the yields of rice and wheat in different treatment plot fluctuated and varied greatly among different years affected by climate and other factors. From statistic results of long-term experiment, increased trends of the yields of wheat and rice were found among different years. The increasing trend of rice yield was more significant than wheat, and yield of wheat fluctuated comparatively larger than rice. Effects of organic manure and crop straw treatments on increasing crop yield were more significant than chemical fertilizer treatments. Yield stability of rice was higher than that of wheat, CV of rice was lower and SYI of rice was higher than that of wheat respectively. The highest yield stability was found in treatment MPK (Manure and fertilizer P, K), but the lowest of that was found in treatment MNPK (Manure and fertilizer N, P, K). Amendments of chemical fertilizer, especially nitrogen fertilizer may lead to decline of crop yield stability. Nitrogen fertilizer was the major factor of yield increasing, but may lead to lower stability of paddy ecosystem. Correlation between crop yield and level of soil nitrogen was more significant. Compared to dry season, yield stability and increasing of wheat was more significant in wheat season, indicated a higher sustainability of paddy soil ecosystem which may be improved with years of cultivation.

Abstract:Delay-dependent H2/H control is studied for a class of switched T-S fuzzy systems. The sufficient condition for delay-dependent asymptotical stability and H2 and H performance of the closed-loop switched T-S fuzzy system are derived. Meanwhile, a switching law and fuzzy controller are designed respectively. Moreover, an optimal problem corresponding with time-delay is provided, and an upper bound of time-delay which ensures the system asymptotically stable is obtained using employing MatLab LMI toolbox. Finally, the effectiveness of the proposed method is demonstrated by a numerical example.

Abstract:A calibration method based on target features circle is proposed, which can determine the camera internal parameters based on the two different CCD images. One CCD image can be obtained in a position, and the other CCD image can be gotten by moving the target or camera to a new position. The principle of the calibration method based on one-step movement is expounded. The geometrical relationship and the criteria that the camera axis is orthogonal to the target plane are proven when the CCD image is circle. Finally, the experiment results verify that the method proposed is effective, and the data of the internal calibration parameters of the camera is given.

Abstract:SiO2 aerogels, the lightest solid material have attracted much attention recently. However, it is difficult to be used in practical applications due to its fragility. A facile one step polymerincorporation sol-gel process, together with a surface modification and a normal temperature drying process, was developed to prepare silica-fiber composite aerogels. Four fibers (polyester fiber, polypropylene fiber, lignin fiber, polycrylonitrile fiber) were selected to enhance the intensity of silica aerogels, respectively. The obtained samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) specific surface area. Results showed that samples have a plenty of hydrophobic methyl group attached to their surface. The continuous network structure composed of silica aerogels of high purity are non-crystallized, porous, surface areas from 800 to 980 m<sup>2</ sup>/g and light weight nano-materials. Adsorption experiment of the above samples over organic solution (benzene, toluene) was tested. The composite aerogels absorbed the organic liquids by nearly 6-8 times its own mass, showing potential application in organic absorption. © (2011) Trans Tech Publications.

Abstract:Using Y2O3, Mn(CH3COO)2· 4H2O as raw materials and glacial acetic acid as solvents, YMn xFe1-xO3 precursors (x= 0, 0.05, 0.1, 0.3, 0.5) have been prepared under 80°C water bath conditions. Perovskite YMn xFe1-xO3 samples were achieved after calcination over 900 °C for 4 h. Structure of the samples was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Ultraviolet obvious diffuse reflection(UV-vis DRS), and Field-emission scanning electron microscopy (FESEM). Photocatalytic activity of the samples was also investigated. Results showed that all the samples with stable perovskite structure had high light absorption in visible-light region, suggesting good visible light harvesting. SEM image showed that the samples were sponge-like and porous agglomerates. Photodecoloration activity of 100 mL Rhodamine B (10 mg/L) was 16∼56 % under illumination for 150 min. Oxygen vacancies of the perovskite may explain the high activity of x = 0.1 sample. © (2011) Trans Tech Publications.

Abstract:The tooth surface geometry of involute arch cylindrical gears is analyzed, a new original processing method for the gear named "tooth surface bi-directional envelop machining" is proposed. By using this method, convex tooth surface and concave tooth surface are machined separately with conical rotating cutterhead. In circumferential direction the involute profile is guaranteed by generating method, while in axial direction cambered surface of involute arch cylindrical gear is enveloping cut by the conical cutting edge of the rotating conical cutterhead. By this method, involute arch cylindrical gear can be machined effectively. With superior performance on transmission, the conception of arch cylindrical gear has proposed for a long time, but the application has not developed well, due to the ideal processing method for the gear that has not been resolved.[1][2] In this paper, the geometry of involute arch cylindrical gears' tooth surface is analyzed, and a new original processing method of involute arch cylindrical gear named "tooth surface bi-directional envelop machining" method is proposed. By this method, involute arch cylindrical gear can be machined effectively. © (2011) Trans Tech Publications.

Abstract:Uniform poly(2-aminothiophenol) nanofibers embedded with highly dispersed gold nanoparticles have been fabricated through a facile templateless one-step method. The diameter of composite nanofibers can be controlled in the range of 200-80 nm by simply tuning the speed of mechanical stirring during materials synthesis. Results from our work will provide insight into the shape-controlled synthesis of other nanomaterials by simply introducing mechanical agitation. Removal of gold nanoparticles in composite nanofibers leads to polymer nanotubes with continuous or incontinuous nanocavities depending on mechanical stirring speeds. Furthermore, morphology-dependent catalytic performances of such composites are also investigated. © 2011 American Chemical Society.

Abstract:The motor of bulb tubular pump unit, embedded in the enclosed bulb, has bad operation environment and requires better cooling facilities. Non-uniform air-gap leads the motor's temperature uneven, causing local temperature over high. The influence factors of non-uniform air-gap were analyzed. The motor's temperature and ventilation velocity distributions with non-uniform air-gap were calculated. And the motor's temperature rise was analyzed. The relation between required ventilation quantity and air-gap's non-uniformity were presented by calculating several examples. The results show that, when the motor has non-uniform air-gap, there is more heat value and less ventilation quantity with small air-gap. Therefore, the motor's temperature increases in large extent. In order to keep the temperature normal, more ventilation quantity is required. Compared with uniform air-gap, ventilation quantity increases by 8.1%, 15.1%, 24.2% and 33.7%, when the non-uniformity is respectively reached 5%, 10%, 15% and 20%. The conclusions can be used to control air-gap's non-uniformity and ventilation system design. © 2011 Chin. Soc. for Elec. Eng.

Abstract:Adding nanofillers to PLA/PCL blends to change their surface and interface properties can improve their phase morphology. Here the selective localization of CNTs and organoclays as the third component in the blend is studied. It is found that clay is selectively localized in the PLA phase and at the phase interface whereas CNTs are mainly found in the PCL phase and at the phase interface. With a reduced viscosity ratio of the blend matrices, the CNTs change their preferred localization from PCL to PLA. The effects of the different selective localization of clay and CNTs on the morphologies are studied. In addition, the crystallization behavior of ternary systems also shows a strong dependence on the selective localization of nanofillers. In biodegradable PLA/PCL immiscible blend systems, clay and carbon nanotubes present different selective localization behaviors. The former is selectively localized in the PLA phase and phase interface, while the latter is mainly dispersed in the PCL phase and phase interface. These two selective localizations can be used as powerful tools to design phase morphology of the matrix blends and to control crystallization of the component polymers. © 2011 WILEY-VCH Verlag GmbH & Co.

Abstract:A quasi three-dimensional heat and advection coupling model of vertical U-bend GHE, which couples the one dimensional fluid model in vertical direction with the two-dimensional transient heat and moisture transfer model in level, was developed using the theory of heat and mass transfer in porous medium and ground water advection. Based on the numerical solution of the model, the effects of ground thermal property parameters and ground water advection on the heat transfer characteristics of U tube GHE were analyzed, the results indicated that the increase of ground thermal conductivity and specific heat can enhance the heat transfer characteristic. At the same time, the exist of ground water advection is benefit for the improvement of heat exchanger between the GHE and thus can improve the operation efficiency of GCHP. The experimental validation shows that the model can simulate the heat transfer process of GHE and provide a theoretical base for the study of the heat transfer characteristic of GHE.

Abstract:(Li, Cu)-doped ZnO thin films were prepared on the n-type Si (100) substrate by means of sol-gel process. The structure, surface morphology and photoluminescence properties of the ZnO films were investigated. The results show that all of ZnO thin film samples have strong c-axis preferred orientation. The visible luminescence intensity of Li-doped ZnO films increases with the dopant concentration. The visible light emission can be attributed to the incorporation of transitions derived from the singly ionized oxygen vacancy to the top of valence band and LiZn acceptor states. Similarly, the yellow-green emission might be due to the incorporation of transitions derived from the singly ionized oxygen vacancy to the top of valence band and CuZn acceptor states. With the increase of Cu dopant concentration, the transition of singly ionized oxygen vacancy to CuZn acceptor states plays a dominative role.

Abstract:By introducing the cylindrical system of vector functions and the corresponding propagating matrix, we present a semi-analytical solution for a layered multiferroic half space under a uniform vertical circular load on its surface. A two-layered system made of BaTiO3 and CoFe 2O4 is analyzed by the proposed method. The coupling feature among the elastic, electric, and magnetic fields and the interplay between the adjacent layers are investigated. In particular, we find that the interfacial elastic, electric, and magnetic fields are very sensitive to the thickness of the surface layer. Consequently, a critical thickness is found for each field quantity when it reaches its extreme value for varying thickness of the surface layer. This striking feature could be very useful as a theoretical reference for the optimal design of surface coatings. © 2011 IOP Publishing Ltd.

Abstract:A novel amperometric biosensor for the determination of catechol was developed accordingly to the electrochemical template procedure. The optimum fabricating conditions of the biosensor were studied. The resulting biosensor with the limit of less than 0.05 μM can be used for detection of catechol in the linear range of 2.5-140 μM. The maximum response current (I max) and the Michaelis-Menten constant (k′m) are 3.08 μA and 77.52 μM, respectively. The activation energy (Ea) of the polyphenol oxidase (PPO) catalytic reaction is 25.56 kJ mol-1 in the B-R buffer. The stability of the PANI-CA biosensor fabricated with the electrochemical template process (retains 86% of the original activity after four months) is much higher than that fabricated with one-step and two-step processes (retains 75% of the original activity after four months). The effects of potential and pH on the response current of the biosensor are also described. © 2010 Elsevier B.V. All rights reserved.

Abstract:We introduce symbolic representation for quantum circuit, and show how n-qubit circuit can be described as a control qubit symbolic vector and a lower-order controlled gate, instead of the representation of higher-order unitary matrix. We extend the loopless Gray code binary generation algorithm and propose n elements k position binary generation algorithm. Besides, a fast quantum simulation algorithm (FQSA) is presented, it divides a qubit state vector into several operand groups, each group is multiplied by the same unitary matrix, and then the output can be given quickly. In contrast to any other state vector based algorithm, FQSA requires less memory, and has an optimal time complexity. The experimental result of QFT indicates that FQSA is more time-efficient and it can provide more qubits circuit simulation under the same condition.

Abstract:A stripping voltammetric assay using a morin modified electrode in a sequential injection lab-on-valve system was developed for the determination of trace amounts of cadmium. The sample and reagent arrangements were achieved by a syringe pump. The target metal ions were accumulated on the morin modified glassy carbon electrode surface, and the quantification step was performed by subsequent anodic stripping voltammetry. The key experimental variables relevant to the voltammetric measurement procedure were optimized. For a 100 s preconcentration time, a linear calibration curve was obtained for a concentration range of 1 to 125 μg L-1 with a detection limit of 0.41 μg L-1. The analytical use of the established method was assessed by applying it to the determination of cadmium in real samples and carrying out recovery experiments. The method was subsequently validated by comparing the results with those given by ICP-OES. © 2011 The Royal Society of Chemistry.

Abstract:There is growing concern about the impact of cooking oil fume condensates (COFCs) on the environment, including on the growth of plants. COFCs contain a wide range of chemical constituents which are closely related to the temperature of cooking oil. Among these components, hydrocarbons are believed to be among the most toxic. Dodecane is one of the principal hydrocarbons implicated. The paper deals with the experiments carried out in laboratory to clarify the toxic effects of COFCs, adding various amounts of dodecane to aquatic solutions in dishes containing the floating aquatic plant Salvinia natans. Inhibitory effects on the vegetative growth of S. natans, i.e. on the development of leaves and buds are reported in the experiments. The production of new leaves is significantly inhibited. The percent inhibition of growth rate (%) in the number of leaves produced is significantly correlated with the concentration of dodecane. LC50 values on day 4 and day 16 after treatment are 190 mg/L and 181 mg/L respectively. Dodecane has no effect on the pH values of test solutions. It is concluded that dodecane has significant effects on the vegetative growth of aquatic plants. S. natans is sensitive to dodecane and might be useful as an indicator of dodecane and thus COFCs pollution.

Abstract:Poly(trimethylene terephthalate) (PTT) nanocomposites containing carbon nanotubes (CNTs) with different surface structure and aspect ratio were prepared by melt compounding for electrospinning. The dispersion state of the CNTs in the composites was then examined utilizing rheology tools. The results show that carboxylic surface functionalized CNTs present better dispersion in the matrix than hydroxy surface functionalized CNTs because the former has stronger affinity to the PTT. Besides surface functionalization, the aspect ratio of CNTs is also vital to their final dispersion. The CNTs with lower aspect ratio are dispersed as individuals or small bundles while those with higher aspect ratio are dispersed mainly as flocs with large hydrodynamic radius, showing higher effective volume fraction. The presence of CNTs has a large influence on the morphologies of electrospun fiber and on the appearances of CNTs in the fibers. In the presence of CNTs with lower aspect ratio, continuous composite fibers are obtained. But the structure of those continuous fibers highly depends on the surface group of CNTs. Carboxylic surface functionalized CNTs are well embedded by the PTT and oriented along the fiber axis during electrospinning, leading to bead-free and uniform fiber morphology; while hydroxy surface functionalized CNTs show tortuous conformations with less orientation in the fibers, and as a result, the obtained fibers show beaded and misshaped morphologies. In the case of higher aspect ratio, however, the CNTs prefer to exist as entanglements or knots in the streamlines, and thereby only beaded or even uncontinuous fibers are obtained. Therefore, the formation and fiber morphology of PTT/CNT composite fibers obtained by electrospinning strongly depend on the surface functional groups of the CNTs, as well as on the CNT structure. © 2011 Elsevier Ltd.

Abstract:The mechanism and kinetic properties of OH-initiated gas-phase reaction of 2,2',4,4'-tetrabrominated diphenyl ether (BDE-47) have been studied at the MPWB1K/6-311. +. G(3df,2p)//MPWB1K/6-31G(d) level of theory. Two types of reactions including hydroxyl addition and hydrogen abstraction have been considered. The calculation results indicate that addition reactions except for the bromo-substituted addition reaction have lower energy barriers than hydrogen abstraction reactions. Hydroxyl radical is most likely to be added to non-substituted C atoms (C(3), C(5), and C(6) atoms). Moreover, for all the reactions with OH radical, the bromo-substituted C atoms encountered the highest barrier compared to that of the rest C atoms. The rate constants and product branching ratios of each pathway have been deduced over a wide range of 200-1000. K using canonical variational transition state (CVT) theory with small curvature tunneling (SCT) contribution. This study can be regarded as an attempt to investigate the OH-initiated photochemical reaction mechanism of polybrominated diphenyl ethers (PBDEs). © 2010 Elsevier Ltd.

Abstract:The method of modeling attack using attack tree was researched. The main research goal was how to effectively use the attack tree model and denote the multi-stage network attacks. Traditional attack tree was expanded and improved. Nodes of attack tree were redefined, and attack risk of leaf node was quantified. Then the mentality and method for establishing MLL-AT (multi-level & layer attack tree) were proposed. Based on the given attack tree, the MLL-ATDL (multi-level & layer attack tree description language) attack description language was given. The improved attack tree can model the attacks more accurately, in particular the multi-stage network attacks. And it can also be used for appraising system risk, distinguishing the different degrees of system security threats caused by different attack sequences.

Abstract:In order to master modern optimal methods, which are suitable for solving large pumping station optimal operation with multivariables. Basic principles of genetic algorithms(GA), particle swarm optimization(PSO) and simulated annealing particle swarm optimization(SA-PSO) were introduced, and the similarities and differences were analyzed. It is concluded that PSO is more simple and efficient than GA. Taking Jiangdu pumping station system in Eastern Route of South to North Water Transfer Project as an example, under the circumstances of certain pump assembly head, selecting the number of running pump units and blade setting angles of water pumps as variables, optimal mathematical models for pumping station operation schemes were established aiming at the least operation cost, meeting the constraint conditions such as total pumping discharge, allowed discharge of single pump and the number of running pump units. GA, PSO and SA-PSO were applied to solve the models respectively to determine the number of running pump units, operation duties of pump units and daily operation cost of each pumping station. Constraint conditions were used to deal with feasible rules, and calculating procedure was programmed with Matlab. The results indicate that the operation costs of the optimum schemes by adjusting pump blade setting angles with SA-PSO are 0.99%-4.22% less than that of the conventional schemes under design blade angles, and among the three optimum schemes, the operation cost of the optimum scheme based on SA-PSO is about 0.22%-2.80%, 0.02%-0.40% less than that based on GA and PSO respectively. Computing times of the three optimizing algorithms are 30, 52 and 25 s respectively. Therefore, SA-PSO is more suitable for solving large pumping station operation optimization problems.

Abstract:A kind of robust mixed non-fragile optimal H2/LQR control with regional pole placement was proposed for an air-breathing hypersonic vehicle (AHV). A new linear uncertain model was developed according to a nonlinear longitudinal model of an AHV and then a multi-objective non-fragile controller was designed that includes regional pole placement, robust guaranteed cost control and optimal H2 control performance indexes for the proposed linear uncertain model. The paper also took the gain variation of the controller into account due to parametric uncertainties of an AHV flight condition and the errors existed in modeling. The existed conditions of the multi-objective non-fragile controller were deduction by linear matrix inequalities (LMIs). Finally, the simulation comparisons between non-fragile controller and traditional controller that without considering the gain variation illustrate the advantages and effectiveness of our approach.

Abstract:A mixed-flow pumping system was selected as the study case based on CFD technologies. Two difference methodologies of flow field analysis and performance prediction were conducted. One method was that the system efficiency was the production of pump efficiency with passage efficiency obtained by separate numerical simulation of suction box and discharge passage without pump. The other one was based on the simulation of whole pumping system including the suction box, discharge passage and pump. The predicted results from the two different methodologies were compared with model system test results, which showed that the predicted errors were different. The error of pumping system efficiency was smaller when the numerical simulation of whole pumping system was adopted, while the error was much greater when the system efficiency was predicted by the production of passage efficiency with pump efficiency, approximately equal only near the best efficiency point. The larger errors in predicting pumping system efficiency for the first method were mainly caused by unreasonable theoretic foundation. Therefore, it is suggested that the suction box, discharge passage and pump should be taken as a whole in numerical simulation and performance prediction and the effect of pump should be considered in the optimal hydraulic design of suction box and discharge passage.

Abstract:In order to further improve the accuracy of predicting winter wheat grain protein content (GPC) by remote sensing, the study analyzed the quantitative relationship between satellite remote sensing variables and GPC. Depending on the partial least squares regression (PLS), the multivariable remote sensing prediction model and the space level distribution map of winter wheat grain protein content were constructed. For the PLS model, the number of the best principal components was 5, and normalized difference vegetation index (NDVI), structure insensitive pigment index (SIPI), ratio vegetation index (RVI), nitrogenous reflection index (NRI) and plant senescence reflectance index (PSRI) were identified as the sensitive remote sensing variables for predicting GPC. The determination coefficient (R2) and the root mean square error (RMSE) between estimated value and measured value of GPC were 0.642 and 0.307%, respectively. The results indicate that PLS method can provide an effective way to improve the accuracy of predicting wheat grain quality at large scale by remote sensing data.

Abstract:The mathematical model of optimal daily operation with variable speed for multiple pump units in single pumping station was constructed by taking the minimal daily electric cost as objective function. Considering the efficiency of variable frequency drive (VFD) varied with the unit rotational speed, the decomposition-dynamic programming aggregation method was applied to solve the model above. Taking minimal daily electric cost as objective function, the water quantity pumped by units as coordinated variable, this model was decomposed into several sub-models of daily optimal operation with variable speed for single pump unit. The constructed aggregation model took water quantity pumped by each pump unit as decision variable, the discrete values of water quantity pumped by pumping station as state variable. Both sub-model and aggregation model were solved by means of dynamic programming method. The decomposition-dynamic programming aggregation method could solve the optimal variable speed operation issues for multiple pump units with different types or the units of the same type with performance differences in single pumping station. Through the study on the operation of No.3 Huaiyin Pumping Station which is the third stage pumping station of South-to-North Water Diversion Project in China, a series of optimization results were obtained.

Abstract:A green hydrothermal method was proposed for the controllable synthesis of ZnO2 nanocrystals and ZnO nanorods, using the common and cost-effective 2ZnCO3•3Zn(OH)2 powder and 30 mass% H2O2 aqueous solution as the raw materials. The characterization results from X-ray diffraction, high resolution transmission electron microscopy, transmission electron microscopy and energy dispersive X-ray spectroscopy indicated that the products synthesized at 100-120°C for 6 h or at 170°C for 0 h were cubic phase ZnO2 nanocrystals; while those synthesized at 170°C for 3-6 h were hexagonal phase ZnO nanorods. The UV-vis absorption spectra showed that the as-synthesized ZnO2 nanocrystals and ZnO nanorods had optical band gaps of about 4.1 and 3.3 eV, respectively. © 2010 Elsevier B.V.

Abstract:We systematically investigate the stability and electronic and magnetic properties of one-dimensional (1D) bimetallic organic sandwich molecular wires (BOSMWs), [CpTiCpTM] (TM = Sc-Co, Cp = C5H 5), [CpCrCpTM] (TM = V, Mn, Co), and [CpFeCpTM] (TM = Cr, Co), using ab initio methods. All the BOSMWs are highly stable due to mixed ionic-covalent bonding. With the exceptions of [CpTiCpV], [CpTiCpMn], and [CpCrCpV] exhibiting antiferromagnetic behavior, all the other BOSMWs are ferromagnetic with tunable magnetic moments. In particular, magnetic moments of [CpTiCpCo] and [CpCrCpMn] can be as high as 5 μB per unit cell. Our calculations further show that [CpTiCpTM] (TM = Cr, Fe), [CpCrCpTM] (TM = Fe, Co), and [CpFeCpCo] are robust half-metals (HMs) with large HM gaps. Most importantly, we identify an empirical valence electron filling rule for these BOSMWs, and a BOSMW is found to be a half-metallic ferromagnet whenever N - 5(10) = 5(7) (N is the sum of the valence electrons of two metal atoms). This electron filling rule, together with the HM equations formulized in this study, can be extended to predict new HM BOSMWs. © 2011 American Chemical Society.

Abstract:Two-stage decomposition-dynamic programming aggregation method has been first proposed and introduced to solve the mathematical model of daily optimal operation for parallel pumping stations with adjustable-blade units. Taking minimal daily electricity cost of single pump station as objective function, the water quantity pumped by each station as coordinated variable, by means of the type of the pump units this model is decomposed into several first-stage sub-model of daily optimal operation with adjustable-blade for single pump station. Then taking minimal daily electricity cost of single pump unit as objective function, the water quantity pumped by each unit as coordinated variable, the first-stage sub-model is decomposed into several second-stage sub-model of daily optimal operation with adjustable-blade for single pump unit which takes the blade angle as decision variable, the discrete values of water quantity pumped by each unit as state variable, and is solved by means of dynamic programming method. The constructed aggregation model takes daily water quantity pumped by each pump unit as decision variable, the discrete values of water quantity pumped by parallel station group as state variable, and is also solved by dynamic programming method. The aggregation process replaces the traditional method of constructing equations. This method has first solved the optimal operation issues for multi-units of parallel stations with various operation modes, time period division and daily average head of each station, and also provided theoretical support for the study on optimal operation of multi-stage pumping stations. Taking Huai'an No.1, No.2, and No.4 parallel pumping stations as a study case, a series of optimization results have been obtained. © 2011 IFIP International Federation for Information Processing.

Abstract:Mining frequent patterns on biosequences is one of the important research fields in biological data mining. Traditional frequent pattern mining algorithms may generate large amount of short candidate patterns in the process of mining which cost more computational time and reduce the efficiency. In order to overcome such shortcoming of the traditional algorithms, we present an algorithm named MSPM for fast mining frequent patterns on biosequences. Based on the concept of primary patterns, the algorithm focuses on longer patterns for mining in order to avoid producing lots of short patterns. Meanwhile by using prefix tree of primary frequent patterns, the algorithm can extend the primary patterns and avoid plenty of irrelevant patterns. Experimental results show that MSPM can achieve mining results efficiently and improves the performance. © 2011 IFIP International Federation for Information Processing.

Abstract:Expounds characteristics of the frame structure and function of a hydraulic walk caterpillar vehicles. A frame structure is designed to suit for a caterpillar running system with hydraulic pump-motor circuit. While to design such a frame, there must be a tradeoff between mechanical property and its mass. Based on establishing the geometric model of the frame, the finite element method is used to analyse the distribution of stress and strain of the frame in its working condition. Furthermore, aim to reduce the mass of the frame, a programme is designed and applied to find the best tradeoff point between requirment and mass. The programme is developed using APDL(ANSYS Parametric Design Language). The simulated example showed that the propose method in this paper can be applied to optimize the frame of caterpillar vehicles. © (2011) Trans Tech Publications.

Abstract:Calixarenes and their derivatives may be a promising material for enzyme immobilization owing to their particular configuration, unique molecule recognition function and aggregation properties. In this paper, p-tert-butylthiacalix[4]arene tetra-amine (TC4TA) was first used as enzyme immobilization material. This attractive material was exploited for the mild immobilization of glucose oxidase (GOD) to develop glucose amperometric biosensor. GOD was strongly adsorbed on the TC4TA modified electrode to form TC4TA/GOD composite membrane. The adsorption mechanism was driven from the covalent bond between amino-group of TC4TA and carboxyl group of GOD and molecule recognition function of TC4TA. Amperometric detection of glucose was evaluated by holding the modified electrode at 0.60V (versus SCE) to oxidize the hydrogen peroxide generated by the enzymatic reaction. The sensor (TC4TA/GOD) showed a relative fast response (response time was about 5s), low detection limit (20μM, S/N=3), and high sensitivity (ca. 10.2mAM-1cm-2) with a linear range of 0.08-10mM of glucose, as well as a good operational and storage stability. In addition, optimization of the biosensor construction, the effects of the applied potential as well as common interfering compounds on the amperometric response of the sensor were investigated and discussed herein. © 2010 Elsevier B.V.

Abstract:Stochastic process algebra models have been successfully used in the area of performance modelling for the last twenty years, and more recently have been adopted for modelling biochemical processes in systems biology. Most research on these modelling formalisms has been on quantitative analysis, particularly the derivation of quantified dynamic information about the system modelled in the face of the state space explosion problem. In this paper we instead consider qualitative analysis, looking at how recent developments to tackle state space explosion in quantified analysis can be also harnessed to establish properties such as freedom from deadlock in an efficient manner. © 2011 Springer-Verlag Berlin Heidelberg.

Abstract:Based on an exact geometric nonlinear theory for plane curved beams, geometrically nonlinear equilibrium equations and boundary conditions governing the nonlinear bending of a simple plane frame structure subjected distributed loads were derived. By using the shooting method to numerically solve the boundary value problem of nonlinear ordinary differential equations, large deformation equilibrium configurations of a simple frame with both straight and the curved beam elements subjected uniformly distributed load were obtained. The theory and methodology presented can be used to analyze large deformation of plane simple frames with a variety of geometries and loadings. © (2011) Trans Tech Publications.

Abstract:To effectively store and control mass data, a path-based Radio Frequency Identification (RFID) data cube construction method was proposed. This method depends only on the size of path database but not the distribution of the RFID system. Some cuboids between the minimal interest layer and the observation layer were chosen to materialize, which costs less time to both construct the cube and answer the path queries from different users. Analytical and experimental results show the effectiveness of this method.

Abstract:Electroless Ni-P/n-CeO2 composite coatings were preparated under the traditional watt acidic plating solution condition, and its anti-corrosion properties were studied and compared. Ni-P/CeO2 composite coatings were co-deposited on A3 steel substrate surface. The results show that the optimal quantity of CeO2 additive should retain 15-20 g/L. Rare earth particles absorb on matrix surface and produce lots of nano-scale nucleus of crystal, refined grain. Only this, nano-CeO2 particle can get dispersed sufficiently and effectively. Rare-earth CeO2 increase the P content(m(P)≥12%). Rare earth particles n-CeO2 produced at micropore and other defects, decrease activity of impurities, refine the crystal boundary, which due to rare-earth CeO2 nano-particle addictive co-deposite with Ni, P. Corrosion test manifests that rare earth additive CeO2 makes porosity lower, the corrosion morphology of coatings has change from corrosive pitting to be general corrosion, the anti-corrosion property and passivity improve in Ni-P/CeO2 coatings. Electric polarization curves are determined by constant potential rectifier has used to study anti-corrosion resistance, the results show that potential ennoblement and corrosion current drop 1 order of magnitude. The polarization curves slightly move to positive direction and decrease corrosion current density. According to the electrochemistry theory, the corrosion property is improved. Besides, the paper also studys the effect upon heating about microstructure, anti-corrosion resistance and so on. It finds that Ni3P precipitation and Ni crystallization take place at 450°C 2 h heat treatment. In addition, Ni-P/CeO2 coatings have sintered phase of NiCe2O4 spinels, precipitated phase CeO2 is priority produced at micropore and other defects. So, Ni-P/CeO2 composite coatings can get diffused sufficiently and effectively, increase grain density, microhardness can reach 1000 HV.

Abstract:The relations between tomato crops and soil transpiration and the microclimatic factors inside and outside bi-span greenhouse were analyzed. The computational fluid dynamics (CFD) model was used to solve the temperature and relative humidity (RH) distributions based on water vapor transmission and solar radiation with the porous models, and the boundary conditions were discussed. The 3-D temperature numerical simulations were tested by means of Fluent software. The results showed the average relative errors of the simulated and the measured values were 5.7% and 2.1%, respectively. The CFD model and the boundary conditions were proved to be validated. Compared to cloudy days, the average temperature was 1.6°C higher and relative humidity was 3% lower in sunny days. The solar radiation had an effect on the temperature and RH distributions. The average temperature was 0.8°C higher and RH was 19% higher for the double density plants than that of single density plants. The temperature and RH distributions were lower near the leeward than the windward inside greenhouse, but a homogeneous pattern was observed in cropping region.

Abstract:We investigated the properties of the spin-1/2 ferromagneticantiferromagneticantiferromagnetic alternating Heisenberg chain using the spin-wave theory. The spin-wave excitation spectra, the sublattice magnetizations and the local bond energies of the model are calculated to be compared with the corresponding properties of the mixed spin (1, 1/2) chain for a range of α. The results demonstrate that all the properties show similar behaviours in the small α limit, so the properties of the mixed spin (1, 1/2) chain can be described using the spin-1/2 ferromagneticantiferromagneticantiferromagnetic alternating Heisenberg chain. © 2010 Elsevier B.V.

Abstract:The chitosan/polycaprolactone(CS/PCL) vascular scaffolds were prepared by electrospinning in order to combine the advantage of chitosan(CS) and polycaprolactone(PCL) into the vascular scaffolds. The obtained CS/PCL vascular scaffolds were characterized by SEM and electronic universal testing machine. The endothelial progenitor cells(EPCs) were implanted in the scaffolds with various mass ratios of CS to PCL. The vascular scaffolds were examined by adhesion rate in different culturing times and the cells breeding was observed. The obtained CS/PCL vascular scaffolds show porous, nano-structured surfaces, similar to the natural extracellular matrix. When the mass ratio of CS to PCL is 0.5, the breaking elongation of CS/PCL vascular scaffolds reaches 31.64%, and the curves of stress-strain indicate that the obtained vascular scaffolds possess good elastic deformation. The adhesion rate of EPCs on CS/PCL vascular scaffolds is 95.1%, the observation of EPCs labeled with CM-DiI(chlormethylbenzamido-1, 1 dioctadecy l-3, 3, 3′, 3′-tetramethylindocarbocyamine)after culturing 72 h by fluorescence microscopy also illustrates that CS/PCL vascular scaffolds are beneficial to cell growth and cell adhesion.

Abstract:Graphene oxide (GO) on a glassy carbon (GC) electrode was directly reduced at -1.0 V in a phosphate buffer (pH 4.15) to form graphene/GC electrode, which was used for the electrocatalytic oxidative polymerizations of aniline, o-aminophenol, and m-aminophenol in the acidic solutions using cyclic voltammetry, amperometric and potentiometric methods. Cyclic voltammograms demonstrate that the oxidation peak of aniline on the first cycle shifts from 1.13 V on the bare GC electrode to 0.76 V on the graphene/GC electrode. In addition, both amperometric and potentiometric methods also demonstrate that graphene can effectively catalyze the electrochemical oxidative polymerization of aniline. Cyclic voltammetry confirmed that graphene can pronouncedly catalyze the electrochemical oxidative polymerizations of o-aminophenol and m-aminophenol, but graphene oxide hardly catalyzes the electrochemical oxidative polymerizations of aniline and its derivatives. The ESR spectrum of graphene is quite different from that of graphene oxide. © 2010 Elsevier Ltd.

Abstract:Selected pairs of phases in the system, not in equilibrium, were brought into contact and the transport between them was evaluated from the changes in volumes with time. The results showed the rate determining factors to be the extremely slow absorption of compounds into the solid acid layer and of water into the surfactant inverse micellar solution. The former factor was referred to the protracted process of modifying the crystalline structure and the latter to the minute diffusion coefficient of the inverse micelles. In the same manner the contact between the lamellar phase liquid crystalline phase and a solid solution of the surfactant in the acid led to the formation of two inverse micellar solutions of different composition separated by a liquid crystalline layer instead of the expected aqueous liquid and one inverse micellar solution, which appeared first after significantly extended times. The equilibration was significantly retarded by the slow diffusion of acid molecules through one of the liquid layers. © Taylor & Francis Group, LLC.

Abstract:The synergistic effect of ultrasonic decomposition of CCl4 and methyl orange (MO) simulated wastewater was investigated. The sonochemical degradation of CCl4 in water is very rapid, while the ultrasonic degradation of MO aqueous solution is very poor. But the ultrasonic degradation of MO can be drastically enhanced in the presence of CCl4. After irradiation for 6 min by using 40 kHz, 0.272 W · cm-2 ultrasound, the degradation ratios of CCl4 saturated aqueous solution (5.23 mmol · L-1) and 24 mg · L-1 MO are 91.83% and 0.85%, respectively. At the same time, the ultrasonic degradation of MO is 79.08% in the presence of CCl4. Under experimental conditions, if the initial concentration of CCl4 is greater than 1.04 mmol · L-1, the sonochemical degradation of MO behaves as a zero-order reaction in kinetics, otherwise, the reaction is a first-order reaction. The sonochemical decomposition efficiency of MO by adding CCl4 increases with the increase of ultrasonic frequency, and the decrease of temperature, and the degradation rate constant of MO is in direct proportion to ultrasonic intensity. The effects of cavitation gases on the MO degradation are listed in the following decreasing order: oxygen > no saturation gas > nitrogen. The degradation mechanism of MO by using US/CCl4 is attributed to chlorine-based free radicals.

Abstract:Based on backstepping, an adaptive neural network control scheme is proposed for a class of perturbed strict-feedback nonlinear systems with unknown time-varying delays and virtual control coefficients. By choosing appropriate Lyapunov-Krasovskii functionals, the unknown time-varying delay uncertainties can be compensated for. The continuous approximation functions are constructed to solve the singularity problem which occurs when neural networks are used to approximate the unknown nonlinear functions. By introducing a new intermediate variable, the derivative of virtual control is guaranteed to be right. Simulation results show that the proposed controller can guarantee that all the signals in the closed-loop system are semi-global uniformly ultimately bounded, and the tracking error converges to a neighborhood of zero.

Abstract:In the current sunlight angle measurement, many photosensitive components are used in digital signal measurement with low precision and the characteristics difference between photosensitive components which affects the results in analog signal measurement. Because the short circuit current of solar cell is alternated with cell's rotation, a method with minor components and large range measurement is put forward, and the angles are obtained by calculating the phase of short circuit current with DFT. The difference between components is avoided because an angle is gotten by once cell rotation. Short circuit current characteristic with rotation angle and test results are presented. The test results show its effectiveness.

Abstract:In order to overcome the shortcomings of traditional algorithms, the algorithm MSPM was proposed. It used longer patterns for mining, which avoided producing lots of patterns with short length. Meanwhile by the use of prefix tree of primary frequent patterns, we extended the primary patterns which avoided plenty of irrelevant patterns. The experimental results show that MSPM not only improves the performance but also achieves effective mining results. © (2011) Trans Tech Publications.

Abstract:Higher pair contacting components is worn more severely than lower pair contacting components due to the larger contact stress on the contact line. To improve antifriction of higher pair contacting components, the paper proposes a new method by which a large number of micro-deep holes are fabricated on the surface of the contacting component. When higher pair operates, contact stress near the contact line will cause obvious elastic deformation and the volume of the micro-deep holes near the contact line will change, resulting in absorbing oil and squeezing oil. Then an oil film with certain pressure is generated around the micro-deep holes, which will improve the lubrication of components greatly. In addition, a test is carried out and its result shows that the cylindrical roller with micro-deep holes performed better in terms of antifriction than the smooth cylindrical roller. © (2011) Trans Tech Publications.

Abstract:Mining closed frequent itemsets in data streams is an important task in stream data mining. Most of the traditional algorithms for mining closed frequent itemsets are Apriori-based which find the frequent itemsets from large amount of candidates, and needs a great deal of time and space. In this paper, an algorithm ItemListFCI for mining closed frequent itemsets in data stream is proposed. The algorithm is based on the sliding window model, and uses a ItemList where the transactions and itemsets are recorded by the column and row vectors respectively. The algorithm first builds the ItemList for the first sliding window. Frequent closed itemsets can be detected by pair-test operations on the binary numbers in the Table. After building the first ItemList, the algorithm updates the ItemList for each sliding window. The frequent closed itemsets in the sliding window can be identified from the ItemList. Algorithms are also proposed to modify ItemList when adding and deleting a transaction. The experimental results on synthetic and real data sets indicate that the proposed algorithm needs less CPU time and memory than other similar methods. © (2011) Trans Tech Publications.

Abstract:In this paper, a prey-predator model with reaction-diffusion is investigated under homogenous Neumann boundary condition. By taking food ingestion and species' moving into account, model is further coupled with Ho¨lling's type II function response and nonlocal delay. Sufficient conditions for the global stability of three equilibria, i.e. positive, semi-trivial and trivial steady states are mainly derived by Lyapunov functional, respectively. Results show that intra-specific competition benefits the coexistence of prey and predator. Numerical simulations are performed to illustrate the analytical results. © 2010 Elsevier Inc.

Abstract:A novel template-free method, which was based on heating the mixture of InCl3-4H2O and thiourea in air from room temperature to 200 or 250 °C, coupled with a subsequent washing treatment using distilled water and ethanol, was proposed for the synthesis of In2S3 hierarchical nanostructure. X-ray diffraction and field emission scanning electronic microscopy demonstrated that the obtained products were pure cubic phase In3S3 urchin-like clusters built up by mainly nanoflakes (about 12-47 nm thick). UV-vis absorption spectra disclosed that the as-prepared In3S3 urchins had optical band gaps in the range of about 2.18-2.26 eV. © (2011) Trans Tech Publications, Switzerland.

Abstract:In a designated verifier proxy signature scheme, one can delegate his or her signing capability to another user in such a way that the latter can sign messages on behalf of the former, but the validity of the resulting signatures can only be verified by the designated verifier. Recently, Lee J-s et al. proposed a new ID-Based designated verifier proxy signature scheme. They didn't analysis the security of their scheme. We found out that anyone can generate a valid signature on any message m and mw he choose. To overcome this flaw in Lee J-s et al.'s scheme, we formalized the notion of designated verifier proxy signature scheme, provide a new ID-Based designated verifier proxy signature scheme. We also analyzed the proposed scheme. © (2011) Trans Tech Publications.

Abstract:In order to optimize supporting structures of bulb tubular pump units and improve the properties, the supports of bulb tubular pump units were divided into 3 hierarchies, i.e. the bearing block support, the bulb support and the pump body support. The support forms of 3 typical bulb tubular pump units were investigated. The shaft deformations and fatigue strength safety factors were calculated through force analysis. Several typical support forms were compared in pump unit reliability, installation, maintainability and overall structure, and the pump system hydraulic performances. The design principles and methods of bulb tubular pump unit supports were put forward in bearing number and their arrangement and installation, the bulb supports and the pump body supports. The results show that supporting forms of bulb tubular pump units affect reliability, stability, installation and maintainability of the pump units and the pump system hydraulic performances. The flexivities of motor rotor and pump impeller reach 0.19~0.39 mm and 0.22~0.62 mm, respectively. The oil film thicknesses of journal bearings and rolling bearings are 0.41~0.53 mm and 0.12~0.17 mm, respectively. When determining the installation height of the bearing saddle, the flexivities of the rotor and the impeller and oil film thicknesses of the bearings should be considered so that the motor's air gap and the clearance between pump blade and shell are evenly distributed. The reliability and hydraulic performances of bulb tubular pump units could be improved by reasonably arranging guide bearings, adopting radiating plate support of the bulb, combining the maintenance channel and the main support which is under the bulb, and using the metal pipe pump structure. The achievements could provide references to optimum design of bulb tubular pump units.

Abstract:A metal core piezoelectric fiber (MPF) is one of the new type piezoelectric devices for sensors and actuators. When an external harmonically varying voltage is applied on electrodes of a cantilevered MPF, it will cause longitudinal vibration. A force appears due to the strain caused by the electric field in the piezoelectric elements. Using the vibration theory of a cantilevered bar, the longitudinal vibration equations of the MPF were derived. The electric displacement was deduced by using the constitutive equations of the piezoelectric element. And the electric charges on the electrodes were given by integrating electric displacement. The total current flowing through the electrode surface and the admittance of the MPF was derived from the electric charges. Using the resonance frequency, the elastic coefficient at a constant electric field S11E was given from the admittance. And using the antiresonance frequency, the electromechanical coupling factor R31 was obtained. The dielectric permittivity under a constant stress Ε 33T was extracted with the lower capacitance. Using above parameters, the piezoelectric coefficients d31 was calculated. One experiment was performed. The theoretical simulations and experimental results showed that this method is effective to measure the properties of MPF.

Abstract:The flow patterns and hydraulic performances of two different bulbs of pump system, i.e. normal type and slin type, were studied. Based on the RNG k-Ε model, the SIMPLEC algorithm was applied to the solution of the discretization governing equation. Using multiple reference frames, the flow details of whole pumping systems whose length was of 10.72D, where D was of the impeller diameter, were obtained. The influences of the flow of pump system on difference bulbs were analyzed. The unsuitable design of bulbs caused flow separation and vortex. The calculation results illustrate that the static pressure contours of two pumping systems which were operated at design flowrate, large flowrate and small flowrate, were similar, and therefore the shape of bulb does not impact on the operation status of impellers. The results showed that the flowrate of minimum loss for slin taper bulb is of 112 percent of design flowrate, while that for normal bulb is of 106 percent of design flowrate. It is not quadratic function between flowrate and hydraulic loss, and the loss is somewhat related with the operating region. 3D numerical computation and model test showed that the performance of slin taper bulb was better than that of normal one, and consequently this type of pump system can be applied in the East Route Project of South-to-North Water Transfers.

Abstract:Stable magnetic nanofluids containing Fe3O4@Polypyrrole (PPy) nanoparticles (NPs) were prepared by using a facile and novel method, in which one-pot route was used. FeCl3·6H2O was applied as the iron source, and the oxidizing agent to produce PPy. Trisodium citrate (Na3cit) was used as the reducing reagent to form Fe3O4 NPs. The as- prepared nanofluid can keep long-term stability. The Fe3O4@PPy NPs can still keep dispersing well after the nanofluid has been standing for 1 month and no sedimentation is found. The polymerization reaction of the pyrrole monomers took place with Fe3+ ions as the initiator, in which these Fe3+ ions remained in the solution adsorbed on the surface of the Fe3O4 NPs. Thus, the core-shell NPs of Fe3O4@PPy were obtained. The particle size of the as-prepared Fe3O4@PPy can be easily controlled from 7 to 30 nm by the polymerization reaction of the pyrrole monomers. The steric stabilization and weight of the NPs affect the stability of the nanofluids. The as- prepared Fe3O4@PPy NPs exhibit superparamagnetic behavior. © 2011 Zhao and Nan.

Abstract:Based on the large deformation theory and considering the axial extension of the beam, the governing equations of post-buckling of a simply supported elastic FGM beam subjected to conservative and non-conservative distributed forces were established. In the analysis, it was assumed that the material properties of the beam vary continuously as a power function of the thickness coordinate. By using shooting method, the nonlinear boundary-value problem was solved numerically and the equilibrium paths as well as the post- buckling configurations of the deformed beam were presented. A comparison between the results of conservative system and that of non-conservative systems were given. The results shows that the features of the equilibrium paths of the the functionally graded beam under non-conservative are evidently different from those to a conservative one. © (2011) Trans Tech Publications, Switzerland.

Abstract:Iron oxyhydroxides as the efficient scavengers for heavy metals have been extensively investigated in iron-rich acid sulfate waters in the presence of Acidithiobacillus ferrooxidans (A. ferrooxidans, an especially important chemolithoautotroph for bioleaching and desulfurization of coal). In this study, we observed the morphology and elemental composition of cells in stationary phase and examined the dynamic variation of iron oxyhydroxides produced in cultures of A. ferrooxidans incubated in modified 9K medium initially including 0.15 M of ferrous iron, in the absence/presence of 0.2 M of chloride (NaCl/FeCl2). Results showed that chloride acclimation had little effect on cellular morphology and elemental uptake that was mainly related to culture medium. Furthermore, schwertmannite with the typical morphology of aggregated spheres covered by some "pincushions" was precipitated first in bacterial cultures in the favorable pH range of 2.9 ± 0.1 to 2.6 ± 0.1. Some of schwertmannite could be transformed to lozenge-shaped jarosite, due to a successively decreasing of pH values. However, the jarosite transformation represented a lag period of 5 and 4 days in the chloride-rich cultures with sulfate at a low level, compared to the cultures with sulfate at a high level, which could be attributed to the influence of sulfate requirement and chloride acclimation. © 2010 American Chemical Society.

Abstract:A new method for the determination of iron (III) has been described. The analytical procedure was based on the fluorescence quenching of salicylfluorone (SAF) by iron (III) and the fluorescence quenching value (ΔF) could be increased in the medium of room temperature ionic liquids (RTILs) (1-ethyl-3-methylimidazolium ethyl sulfate)/SDS (sodium dodecyl sulfate). The main factors influencing the fluorescence quenching (ΔF) were investigated in detail. Under the optimal conditions, the linear equation was \Delta {{F }} = {{319c }} + {176}.{5}\; (c:μg&bullmL-1, r∈=∈0.9936).

Abstract:By establishing the Markov model for a long-range correlated time series (LRCS) and analysing its evolutionary characteristics, this paper defines a physical effective correlation length (ECL) τ, which reflects the predictability of the LRCS. It also finds that the ECL has a better power law relation with the long-range correlated exponent γ of the LRCS: τ = K exp(-γ/0.3) + Y, (0 < γ < 1)-the predictability of the LRCS decays exponentially with the increase of γ. It is then applied to a daily maximum temperature series (DMTS) recorded at 740 stations in China between the years 1960-2005 and calculates the ECL of the DMTS. The results show the remarkable regional distributive feature that the ECL is about 10-14 days in west, northwest and northern China, and about 5-10 days in east, southeast and southern China. Namely, the predictability of the DMTS is higher in central-west China than in east and southeast China. In addition, the ECL is reduced by 1-8 days in most areas of China after subtracting the seasonal oscillation signal of the DMTS from its original DMTS; however, it is only slightly altered when the decadal linear trend is removed from the original DMTS. Therefore, it is shown that seasonal oscillation is a significant component of daily maximum temperature evolution and may provide a basis for predicting daily maximum temperatures. Seasonal oscillation is also significant for guiding general weather predictions, as well as seasonal weather predictions. © 2011 Chinese Physical Society and IOP Publishing Ltd.

Abstract:In the present paper, the hydrophobicity ionic liquid 1-butyl-3- methylimidazolium hexafluorophosphate ([C4mim][PF6]) was synthesized with 1-methylimidazole and butylbromide and equimolar ammonium hexafluorophosphate, which was applied to preconcentration for trace gold. The factors which may affect preconcentration of gold were investigated. The experimental results showed that the absorbance was linear when the concentration of gold was in the range of 0.40~16.00μg · mL-1, with linear equation A = 0.00763c +0.07387(c:μg · mL-1), correlation coefficient r = 0.9991, and detection limit 0.072 μg · mL-1. The method was applied to the determination of trace gold in water samples satisfactorily.

Abstract:In order to study the influence of middle division pier on the hydraulic performance of a low head pump system, 3D turbulent numerical simulation method was applied to calculate the flow patterns and hydraulic losses of a separated conduit of a certain low head pumping station. Under the design discharge that the middle division pier was set in the conduit, the hydraulic losses calculated were increased by 0.024 m and 0.033 m, respectively. Transparent conduit model experiments were carried out to validate the calculation results. The results of the model experiment are consistent with those of the numerical simulated ones. Based on the numerical simulation and model experiment results, the influence of the pier on the hydraulic performance for both siphon outlet conduit and straight outlet conduit were studied. The results indicate that the flow pattern in the conduit is asymmetrical due to the influence of the flow circulation at the outlet section of the pump guide vane. And consequently, the hydraulic performance of the conduit was affected to a certain extent by the pier. The longer the pier, the larger the influence. Therefore, the pier is unprofitable to the hydraulic performance of the conduit and the pier for a large pumping station with low head could be removed if the structural design condition of the conduit is permitted.

Abstract:In a network described by a graph, only topological structure information is considered to determine how the nodes are connected by edges. Non-topological information denotes that which cannot be determined directly from topological information. This paper shows, by a simple example where scientists in three research groups and one external group form four communities, that in some real world networks non-topological information (in this example, the research group affiliation) dominates community division. If the information has some influence on the network topological structure, the question arises as to how to find a suitable algorithm to identify the communities based only on the network topology. We show that weighted Newman algorithm may be the best choice for this example. We believe that this idea is general for real-world complex networks. © 2011 Chinese Physical Society and IOP Publishing Ltd.

Abstract:Locally discriminating projection (LDP) is a new subspace feature extraction method which takes special consideration of both the local information and the class information. For LDP method, the image matrix data are vectorized to find the intrinsic manifold structure, and the dimension of matrix data is usually very high, so LDP cannot be performed because of the singularity of scatter matrix. In addition, the matrix-to-vector transform procedure may cause the loss of some useful structural information embedding in the original images. Thus, in this paper, a novel method, called 2D locally discriminating projection (2DLDP), for face recognition is proposed. Experiments conducted on the ORL and FERET face database demonstrate the effectiveness of the proposed method. ©2010 IEEE.

Abstract:Orthogonal Frequency Division Multiplexing (OFDM) has recently been focused on in high-data-rate wireless communication research. But the high Peak-to-Average Power Ratio (PAPR) is one of the main obstacles to limit wide applications of OFDM. In this paper, based on the thorough research of selective mapping (SLM) and partial transmit sequences (PTS), the modified SLM schemes with the Riemann matrix are proposed. In the proposed schemes, it is not needed to exchange side information between transmitter and receiver. And it is shown that better PAPR reduction performance is achieved as compared to the basic SLM by Monte Carlo simulations. ©2010 IEEE.

Abstract:A facile and effective route has been proposed to synthesize gold nanoparticles with controllable size that uniformly deposited on surfaces of polyaniline (PANI) nanofibers, where PANI nanofibers themselves act as both supporter and reductant. Effects of reagent concentration, reaction time, and temperature on size and uniformity of gold nanoparticles are investigated. Furthermore, a functional doping acid of typical thioglycolic acid (TA) that introduced in PANI nanofibers shows good potential for improvement in uniformity of composites and control over gold nanoparticle size. Fourier transform infrared (FTIR), X-ray diffraction (XRD), and ultraviolet-visible (UV-vis) spectra are used to characterize PANI nanofiber/gold nanoparticle composites. Adaptability of this approach for making PANI nanofiber composites with other noble metal nanoparticles, such as platinum, silver, and palladium nanoparticles, is also studied. A possible formation mechanism involved has been then proposed. Furthermore, PANI nanofiber/gold nanoparticle composites are found to serve as effective recycled catalysts to activate the reduction of 4-nitrophenol (4NP) in the presence of NaBH4, where size of gold nanoparticles is found to play the determining role on catalytic activity. © 2010 American Chemical Society.

Abstract:Poly(Ε-caprolactone) (PCL) has attracted much attention in recent years due to its good biodegradability and biocompatibility. As a semicrystalline polymer, the final properties of PCL strongly depend on its bulk crystallization level. However, PCL shows a lower crystallization temperature and rate than other aliphatic polyesters, which restricts its range of applications. To improve the crystallization is hence a key problem to enhance the performance of PCL materials. In this work, a thermotropic liquid crystalline polymer (TLCP) was used as a nucleating agent to improve the crystallization of PCL. The PCL/TLCP blend with the maximum TLCP content of 10 wt.% was prepared by melt mixing. The nonisothermal crystallization behaviour of the PCL matrix was studied using differential scanning calorimetry (DSC) and polarized optical microscopy (POM), and the crystallization kinetics was then further analysed by methods including the Avrami, Ozawa, Mo, Ziabicki, Lauritzen-Hoffman and Kissinger models. The results showed that the presence of the solid TLCP particles could enhance crystallization temperature of the PCL matrix evidently at very small content levels (1 wt.%). Although the mobility of the PCL chain segments decreased with increasing TLCP content, heterogeneous nucleation by TLCP particles always played a dominant role in the overall crystallization. Therefore the blends showed higher crystallization rates and ability than those of pure PCL. The kinetic analysis and the data obtained in this work could be useful to optimize the processing conditions and to improve the crystallization of PCL. © Smithers Rapra Technology, 2010.

Abstract:The backstepping procedure is one of the tools, which provides control law synthesis for nonlinear smooth systems. A class of nonlinear systems which is so-called strict-feedback systems is usually considered, but the backstepping procedure applied to pure feedback nonlinear systems results sometimes in a control law, which exhibits singularity. In this paper, a class of pure nonlinear systems which satisfies some given sufficient conditions is described, and the derived control law is numerically well posed. Another class of systems which has weakened conditions than above discussed systems is also considered which makes the application scope of backstepping technique more extensive. The simulation results demonstrate that the control law of this class of systems does not exhibit singularity, which means division by zero or ill-conditioned.

Abstract:Based on the principle of sliding mode control and property of Nussbaum-type functions, an improved adaptive neural control scheme is proposed for a class of MIMO nonlinear time-varying delay systems with unknown function control gains. By choosing appropriate Lyapunov-Krasovskii functionals, unknown time-varying delay uncertainties are compensated for. In this paper, the restriction of control gains is relaxed, and the system considered here is more general. By utilizing Young's inequality, the assumption of time-varying delay uncertainties is relaxed. Moreover, only one parameter is adjusted in each subsystem, and the complexity of implementation is reduced. By theoretical analysis, the closed-loop control system is proved to be semi-globally uniformly ultimately bounded. Finally, simulation results are provided to illustrate the effectiveness of the proposed approach.

Abstract:In situ ESR-electrochemical measurements indicate that the distinct redox properties of polyaniline synthesized using the interface polymerization method (labeled IP-polyaniline) are strongly related to its unpaired spin density. IP-polyaniline in a 1.0 M NaCl solution of pH 5.5 still holds stronger ESR signals at a wide potential range, which results in its high redox activity in this solution. The influence of pH on the potential range for the formation of polaron is detected. Also, some unusual phenomena are observed in the measurements of ESR signal intensity as a function of applied potential, for example, the ESR signal intensity of IP-polyaniline in 0.20 M HCl solution decreases with increasing potential from 0.30 to 0.80 V accompanied with the peak-to-peak line width δHpp of the ESR signal increasing from 0.30 to 0.60 V, and then, however, δHpp decreases pronouncedly as the potential increases further. The results from measurements for the ESR susceptibility of IP-polyaniline as a function of temperature demonstrate the presence of the conversion of the temperature-dependent Curie susceptibility to the temperature-independent Pauli susceptibility at the temperature range 135-335 K; however, the ESR susceptibility of IP-polyaniline increases again from 335 to 375 K. The δHpp value increases very obviously from 135 to 195 K and then decreases with increasing temperature up to 375 K. © 2010 American Chemical Society.

Abstract:An output feedback control scheme combined with backstepping, fuzzy logic system and adaptive control is proposed for the output tracking control problem of a class of nonlinear systems with input delay and disturbances. A filter and a virtual observer are constructed to substitute the immeasurable system state. Fuzzy logic systems are employed to estimate the unknown continuous functions. The control scheme ensures that the closed-loop system is semi-globally uniformly ultimately bounded (SGUUB). The tracking error is proved to be bounded and ultimately converges to an adequately small compact set. The feasibility is investigated by a simulation example.

Abstract:Perceptual transparency and robustness are conflicting requirements. To ensure the security of the watermark how to choose the embedding position and intensity is a difficult problem. Chaotic system has characteristics of sensitivity to initial value and unpredictability. High-dimensional chaotic systems have advantage of higher secrecy, so this paper chooses Lorenz chaotic attractor to encrypt binary watermark image. Through the statistic analysis of block energy of the host image, which is applied DWT repeatedly up to the third level, so watermark adaptively embedded into the greatest coefficients which belong to the selected blocks by using the properties of human visual system. Additionally, to realize the blind digital watermarking extraction, chaotic sequence is also applied in selected wavelet coefficients to change the original value of the inherent relationship between wavelet coefficients. Theoretical analysis and experiment results show that the proposed algorithm has high robustness and better performance of perceptual transparency.

Abstract:We investigate the problem of finding the frequent items in a continuous data stream. In the literature, most of the existing algorithms for mining frequent items over data streams do not emphasis the importance of the more recent data items. We present an efficient algorithm F-Stream based on sliding window for computing frequency counts exceeding a user-specified threshold over data streams. Our algorithm can detect Ε-1-approximate frequent items in a data stream using O(Ε-1) memory space and the processing time for each data item is O(Ε-1). Extensive experimental results show that F-Stream outperforms other methods in terms of accuracy, memory requirement, and processing speed. © 2010 Binary Information Press.

Abstract:Chitosan (CS)/polylactic acid (PLA)/tripolyphotspate (TPP) nanosized microcapsules were prepared by emulsion-evaporation. The average diameter of the obtained nanosized microcapsules was around 100-300 nm, and a homogeneous size distribution and good dispersion were observed. The entrapment efficiency of the nanosized CS/PLA/TPP microcapsules for rapamycin was increased with the increase in amount of PLA. When the ratio of CS to PLA was 80 to 20, the entrapment efficiency of CS/PLA/TPP nanosized microcapsules for rapamycin reached the highest (89.8±1.72%). It was also observed that The RAPA entrapment efficiency reached its highest at 20% of addition dosage of RAPA. Copyright © 2010 American Scientific Publishers All rights reserved.

Abstract:Research community on distributed systems, and in particular on peer-to-peer systems, needs tools for evaluating their own protocols and services. Since an experimental evaluation is not always feasible, simulations are becoming the most popular and efficient tools for investigating and validating peer-to-peer systems. Nevertheless, the majority of them are customized simulators, either poorly documented or not extensible to other protocols and settings, so those simulators do not serve general overlay evaluation purposes. Thus, in this paper we are mainly interested in extensible, scalable, high-level overlay and simulation frameworks. In particular, considering the disadvantage of packet-based P2P simulator, such as big overhead and bad scalability, and the advantage of flow-based P2P simulator, such as more universal and good scalability, designing scheme and important components of a flow-based universal peer-to-peer simulator are introduced. As exemplified in this paper by means of the simulator of Chord and Gnutella P2P systems we validated its feasibility. © 2010 Binary Information Press.

Abstract:Collaborative filtering algorithm is one of the most successful technologies used in personalized recommendation system. However, traditional algorithms focus only on user ratings and do not consider the changes of user interest and the credibility of ratings data, which affected the quality of the system's recommendation seriously. To solve this problem, this paper presents an improved algorithm. Firstly, the user's rating is given a weight by a gradual time decrease and credit assessment in the course of user similarity measurement, and then several users highly similar with active user are selected as his neighbor. Finally, the active user's preference for an item can be represented by the average scores of his neighbor. Experimental results show that the algorithm can make the neighbor recognition more accurately and enhance the quality of recommendation system effectively.

Abstract:The flow pattern in the forebay of pumping station is of very important influence on the operation of the pumps. The different kinds of unlike flow pattern, such as large scale circulations and vortices, are often found in the forebay of pumping station especially with multi-pumps. This paper takes the study on improving the flow pattern in the forebay to ensure a good flow condition for pumps operation. The computational results of three dimensional flow fields in an original designed forebay were obtained and a large circulation was found in the forebay on the side which caused serious problems to the operation of pumps. A typical combined means were applied to improve the flow motion. The computational results of the flow fields shows that the large circulation was eliminated and the flow distribution was improved, which was verified by the model test. The improved design has been successfully used to a large pumping station. Copyright © 2010 by ASME.

Abstract:Image fusion method based on multiscale transform (MST) is a popular choice in recent research. Sharp frequency localized contourlet transform (SFLCT) that significantly outperform the original contourlet transform is proposed. Commonly, the upsamplers and the downsamplers presented in directional filter banks of SFLCT make the resulting image not shift-invariant and easily cause the pseudo-Gibbs phenomena. In order to suppress the pseudo-Gibbs phenomena, we apply cycle spinning as compensation. Then, the coefficients of shifted images are calculated. We take the following image fusion rules. First, cycle spinning the source images, the shifted images are obtained. Second, selecting the low-frequency coefficients by the local energy method and calculating the high-frequency coefficients by the sum modified Laplacian (SML), and the coefficients fusion follows. Third, applying the inverse SFLCT and the inverse cycle-spinning sequentially, the image is reconstructed. Numerical experiment results show that the proposed method significantly outperform the wavelet transform, the pyramid transform and the curvelet transform both in visual quality and in quantitative analysis. © 2010 Binary Information Press.

Abstract:In the past decades, a number of parallel manipulators have been extensively studied. However, most efforts are dedicated to six degrees of freedom (DOF) or three-DOF manipulators. There is a need for equipment providing more than three DOF's arranged in parallel and based on simpler arrangements than six-DOF arrangements in application. This paper presents a novel four-DOF parallel platform manipulator with base mounted prismatic actuators. The manipulator is driven by four linear actuators. The movable platform of the manipulator can translate along two directions and rotate around two axes respectively. The kinematics model is formulated, which describes the inverse and forward kinematics transformation. It is very easy to develop a five-axis NC machine-tool which is of large-workspace based on the four-DOF parallel mechanism presented in this paper. © (2010) Trans Tech Publications.

Abstract:Multivariate regression problem is a classic problem in the analytical chemistry field. Some conventional methods such as MLR and PLS have been used to cope with this problem, but these methods cannot tackle nonlinear problems. Kernel methods including Kernel Ridge Regression, Kernel-based Orthogonal Projections to Latent Structures, Support Vector Regression and Gaussian Process Regression have been applied to the multivariate regression problem in the determination of three aromatic amino acids (phenylalanine, tyrosine and tryptophan) in their mixtures by fluorescence spectroscopy. The results of the cross validation method show that the above mentioned kernel methods perform better than conventional methods. Furthermore, feature selection is proposed for these kernel methods to remove redundant features. © 2010 Binary Information Press.

Abstract:As the limited depth-of-focus of optical lenses, it is usually difficult to get an image that contains all information of the objects in focus. Multi-focus image fusion method can solve this problem effectively. A new multi-focus image fusion method was proposed, which is based on curvelet transform. After analyzing the classical multi-focus image fusion method, we use the maximum local energy method to calculate the energy of two images. Firstly, we got coefficients of two different focus images by curvelet transform; Secondly, we select the low-frequency coefficients by maximum local energy, and through a sliding window, obtained output the Maximum energy pixel information. Then the high-frequency coefficients are gotten by absolute maximum method; Finally, the fused image was obtained by performing an inverse curvelet transform. The experimental results show that the method performs well. Compared with wavelet transform method, median pyramid method, this method can get better performance. © 2010 IEEE.

Abstract:The DS-CDMA system has a serious problem that is the multiple-access interference (MAI). Usually, people use the Multi-User detection (MUD) to cancel the MAI. The Multi-User detection makes the best use of the information of other users to cancel the MAI. Indeedly, MUD can cancel the MAI completely, but it has very large computational burden and it increase the noise of the system, besides, it needs to compute the reversion of the matrix which causes the unstable of the system. The new blind detection method (auxiliary vector filter) of anti-MAI, based on Wiener filter, is studied in this paper. The method needs no more modulation, and no inversion of matrix. Also it can be blindly applied to the forward (base-to-mobile) link and its complexity is very low. The simulation results indicate that the auxiliary vector filter can completely cancel the MAI in DS-CDMA system, and its performance is much better than the matched-filter (MF), the decorrelating filter and the MMSE Multi-User Detection. © 2010 IEEE.

Abstract:Orthogonal Frequency Division Multiplexing (OFDM) has been focused on in high-data-rate wireless communication research. But the high Peak-to-Average Power Ratio (PAPR) is one of the main obstacles to limit wide applications of OFDM. In this paper, based on the thorough research of selective mapping (SLM), two modified SLM schemes with the standard arrays and the Riemann matrix are proposed. In the proposed schemes, it is not needed to exchange side information between transmitter and receiver. And it is shown that better PAPR reduction performance is achieved as compared to the basic SLM by Monte Carlo simulations. © 2010 Binary Information Press.

Abstract:This paper represents the relationship between the stability of stairs climbing and the centroid position of the search and rescue robot. The robot system is considered as a mass point-plane model and the kinematics features are analyzed to find the relationship between centroid position and the maximal pitch angle of stairs the robot could climb up. A computable function about this relationship is given in this paper. During the stairs climbing, there is a maximal stability-keeping angle depends on the centroid position and the pitch angle of stairs, and the numerical formula is developed about the relationship between the maximal stability-keeping angle and the centroid position and pitch angle of stairs. The experiment demonstrates the trustworthy and correction of the method in the paper.

Abstract:Since the spot is elliptical when the cylindrical laser comes to the spatial plane, it proves that the laser spots in the CCD images, which are acquired by binocular stereo vision, are also elliptical. Through image edge extraction in image processing, it can obtain space equations of imaging ellipse edge by least square ellipse fitting, which can be transformed into the standard ellipse equations through translation and rotation. Selecting one point of the right imaging ellipse and the left and right camera coordinate system origins, by which a plane is constructed to make simultaneous solution with left imaging ellipse curves so as to obtain the corresponding matching points. From the selective point of right imaging ellipse and right camera coordinate system origin it can make one spatial straight line and from the corresponding analytical point of left imaging ellipse and left camera coordinate system origin it can make another spatial straight line, from which it will obtain the point of intersection which is the point on the spatial plane. With the change of the selective point of right imaging ellipse in a circle, a number of points on the spatial plane can be acquired to determine the spatial plane. The numerical results show that the method is effective and feasible. © 2010 IEEE.

Abstract:The Interactive Electronic Technology Manual is a core element of the equipment support, and using informal means to express automatic reasoning and consistency checking of knowledge systems that can not be carried through by process knowledge. This paper, in cognizance of the high frequency of procedure description in IETM, taking troubleshooting process as an example, puts forward a procedural representation based on labeling transition system, and realizes the XML file storage in procedure description. As a result, the machine can read and operate these data. Meanwhile, this paper designs a quantitative calculating method of process semantic proximity to provide a candidate set of semantic proximity sorting as the result of procedural knowledge retrieval. Compared with existing methods, this method uses status to express the program node information, characterizes change of state by action, and comprehensively considers human-computer interactions. The XML-based procedural representation and storage facilitate interoperability between multiple systems. The formal representation of process knowledge well characterizes the fault diagnosis process in the project of Interactive Electronic Technology Manual.© 2010 ACADEMY PUBLISHER.

Abstract:The technique of two-dimensional principal component analysis (2DPCA) is analyzed and its essence is revealed. The image total scatter matrix of 2DPCA is in nature equivalent to the sum of all total scatter matrices of m training subsets in which the kth subset is formed by the kth line of each of all training images, where m is the number of lines contained in an image. Based on this result, the true reason why 2DPCA outperforms PCA is uncovered, i.e., different from the traditional PCA using only global information of images, 2DPCA combines the local and global information of images simultaneously and alternative more transparent and understandable 2DPCA algorithm is developed. Finally, some relations to PCA and MPCA and 2DPCA are shown. © 2010 IEEE.

Abstract:With the development of multicore chips, it is of great need for people to study the optimization algorithm of matrix operation under multicore environment, so as to make full use of the CPU power; however, the existing parallel algorithm for matrix operation can hardly have the best of multicore chips. To make the traditional applications benefit from multicore processors, the traditional Gaussian Elimination algorithm is improved to enhance its parallel performance under multicore architecture by matrix partition. The stability of the original algorithm is guaranteed. The hit rate of cache is improved by adjusting the computation sequence, the experiment shows that the speedup can reach almost 3 under 4 core CPU environments when evaluating the inverse of dense matrix. © 2010 Binary Information Press.

Abstract:Multiferroic Bi5Fe1-xCox Ti3O15 (x=0~0.6) ceramics were prepared using solid state reaction method. XRD pattern confirmed the single phase in all prepared samples and Raman scattering technique was also used to study the crystal structure. The remanent magnetization (2Mr) is increased to a high value of 2.3 mA · m2/kg with the cobalt content of 0.5. This value is two orders of magnitude greater than that of non-doped one. The promising ferromagnetism is attributed to the coupling arising from local Fe O Co clusters as well as the influence of net magnetic moment of Fe O Co clusters on the magnetic behavior. The remanent polarization (2Pr) is increased by a small amount of cobalt of 0.1, then decreased with further doing of cobalt up to 0.4, after that, 2Pr is increased again up to a cobalt content of 0.6. The dependence of 2Pr on cobalt content is attributed to the joint effect of lattice distortion, charge compensation and the change of covalent bonding condition.

Abstract:In the distributed condition, this paper proposes a distributed sequence fuzzy concept lattice model and an algorithm DseqFuzCL(distributed sequence fuzzy concept lattice) for incremental construction of the distributed sequence fuzzy concept lattice. The algorithm first builds local sequence fuzzy concept lattices according to the local sequence fuzzy formal context in every single computer system, and then a global sequence fuzzy concept lattice is obtained by merging local sequence fuzzy concept lattices. The experimental results show that the algorithm DseqFuzCL owns excellent performance on the time-spatial complexity, and possesses better performance than algorithm SeqFuzCL. Simultaneously, the algorithm DseqFuzCL provides theoretical foundation for mining distributed sequence pattern. © 2010 Binary Information Press.

Abstract:Based on the idea of integrated design, a drive-transmission integrated linear electromechanical actuator is developed. The actuator consists of a permanent magnet synchronous motor (PMSM), a ball-screw and shells. By using coaxial assemblage, the ball-screw is inserted into the hole of the hollow motor rotor and the nut of the ball-screw connects with the motor rotor. In order to restrict the ball-screw rotating relatively to the shell, splines machined respectively on ball-screw and the shell come into being a spline pair. A driver based on a DSP processor and IGBTs plus a position feedback resolver forms a precise servo system. © (2010) Trans Tech Publications.

Abstract:The two-floor flow passages pumping system with the simple structure is well practical in the Basin of Yangzi River downstream. However, this kind of pumping system has some disadvantages, such as low efficiency, easy to appear submerse vortex in discharge flow passages which causes the unit vibration and does harm to the operating of pump unit. In order to solve these problems, the design scheme with a new curve of diffusing outlet structure and inlet cone put forward, which are used in the renovation of the two-floor flow passages pumping station. With the numerical simulation of the two-floor flow passages pumping system, the flow fields are analyzed, and the external performance curves are obtained. To verify the calculation, a model tests were done using the standard model of pump?The test results are compared with the performance curves of numerical simulation. Good agreement of two results is found in the high efficiency area, which can show the calculation is believable. The new design improves the efficiency of pumping system significantly and eliminates the submerse vortex, also can guarantees the economy and security of operating. Copyright © 2010 by ASME.

Abstract:Based on the principle of variable structure control, an improved adaptive control scheme is proposed for a class of more general uncertain MIMO nonlinear time-varying delay systems with unknown disturbances and nonlinear dead-zones. Neural networks are utilized to approximate the unknown nonlinear functions in the design. The unknown time-varying delay uncertainties are compensated for using appropriate Lyapunov-Krasovskii functionals. The restrictions of the control gains are relaxed by utilizing the quadratic-type Lyapunov functions. Only one adaptive parameter needs to be adjusted in each subsystem, and the complexity of control algorithm is reduced. It is proved that the proposed design method is able to guarantee semi-global uniform ultimate boundness of all the signals in the closed-loop system. Finally, simulation results are presented to illustrate the effectiveness of the proposed approach. © 2010 Binary Information Press.

Abstract:Due to the lack of processing capacity in workshop, we need to outsource productive tasks to our partners. In this paper, an integrated model of collaborative planning and scheduling with tasks dividable is established, which aims to reach the target of minimum sum with collaborative fee and processing cost. Because of the necessary in synchronous decision-making with continuous and discrete problems that mixed together, a novel hybrid evolutionary algorithm is presented. An integrated encoding scheme with collaborative planning encoding and scheduling encoding in one chromosome is designed for the algorithm, which uses differential evolution algorithm for continuous optimization, and genetic algorithm for discrete optimization. As a result, we obtain collaborative optimization in the two phases of production planning and scheduling. The experimental results show that the proposed algorithm is an effective method to solve the integrated problem of collaborative planning and scheduling. © 2010 Binary Information Press.

Abstract:Encoding can express the hierarchical relationship in the area of mining the multi-level sequential pattern, up to now all the algorithms of which find frequent sequences just according to frequency, but items have different importance in the real applications, therefore the weight constraint involved to the entire mining process is crucial. The MWSP algorithm based on the candidate generation-and-test approach is one of the best algorithms of the weighted sequential pattern mining, however, which will easily generate the situation of candidate combinatorial explosion during the mining process. Therefore, this paper presents the algorithm PMWSM, which adopts prime encoding to decide the parent-child relationship between different levels by one step of division operation, introduces the concept of K-minimum weighted support count to push weight constraint into the multi-level sequential pattern mining, utilizes the principle of prefix projection database to avoid the occurrence of candidate combinatorial explosion, and takes full advantage of the minimum weighted support count to optimize the algorithm. The experimental results show that the algorithm PMWSM is more effective than the algorithm MWSP on mining multi-level weighted sequential patterns from the sequence database.

Abstract:This paper proposes a mathe, matical model of optimal combination operation of adjustable blade with variable speed for a single pump unit in consideration of tidal levels and peak-valley electricity prices. In this model, we use an objective function to minimize the electricity cost of daily operation, adopt a stage variable to divide one day period into several periods and two decision variables of setting angle and pump speed for each period, and impose a constraint condition of pumping a certain volume in a given period. To optimize this complicated system, we put forward a method that optimizes the setting angle by orthogonal experiment and the pump speed by dynamic programming. Through a comparative analysis of combination operation, adjustable blade operation and variable speed operation of the Jiangdu No. 4 pump station, we conclude that under the existing condition of head variation, whether or not the peak-valley electricity prices are considered, this station has no need of adopting the optimal combination operation, and thus no need of the frequency conversion equipments. © Copyright.

Abstract:Through a large amount of experiments and trial road pavement, the strength, flexural elastic modulus and anti-cracking performance of cement-stabilized aggregate modified with SBR emulsion and polypropylene fibers were compared. The results show that both SBR emulsion and polypropylene fibers can effectively improve the flexural and splitting strength of cement-stabilized aggregate, and decrease the flexural elastic modulus at the mean time. SBR emulsion has an advantage over polypropylene fibers on improving the flexural and splitting strength of cement-stabilized aggregate, but it is inferior than polypropylene fibers on decreasing its flexural elastic modulus. Both polymers can improve cement-stabilized aggregate's anti-cracking performance, and polypropylene fiber has a more significant effect.

Abstract:The existing methods and techniques of rice viscosity measurement were analyzed and the mechanism in measuring rice viscosity based on material characteristics was investigated in this paper. Then, an automatic system for measuring viscosity of cooked rice was developed and quantitative characteristics used to express rice viscosity by the average slope of unloading distortion curve were established. Results showed that the system could distinguish the viscosity difference between rice varieties and detect the change of rice viscosity with cooking time for the same variety. Therefore, this system can meet the requirements in assessing and evaluating rice viscosity, which is an important factor for cooked rice quality, and provide a convenient and accurate way for rice quality measurement.

Abstract:Since RFID technology has being used in more and more applications, a great number of data records with simple format are generated. How to storage and management of RFID data has become an important issue in decision making. Different to normal data records, RFID data contains potential moving paths of items, and it has the characteristics of massive, multi-dimensional and multi-hierarchical, so we must apply new methods in RFID data management. Considering the various distribution of RFID system, we propose a new cubing method to manage RFID data, whose efficiency depends only on the size of path database. In this method, we pre-compute the path database using the concepts of the minimal interest layer and the observation layer, and then choose some suitable cuboids to materialize, which costs less time to respond the path queries from different users in RFID system. Experimental results show our method is effective and efficient. © 2010 Binary Information Press.

Abstract:Effect of quenching on microstructure, ferroelectric and dielectric properties of bismuth layer-structured ferroelectrics SrBi4Ti4O15 and Sr2Bi4Ti5O18 were investigated. The microstructure of these two samples does not change after being quenched at different temperatures. Their ferroelectric properties are improved significantly when quenched at high temperature (above Curie temperature). Remanant polarizations are increased while coercive fields hardly change. For SrBi4Ti4O15 quenched at 600 °C and 800 °C, the remanant polarization is increased by 35% and 88% in comparison with that of the unquenched sample. The remanant polarization of Sr2Bi4Ti5O18 is increased by 28% after being quenched at 400 °C. In addition, the dielectric measurement suggests that quenching can increase relative dielectric constant and reduce dielectric loss. Quenching above the Curie temperature can weaken defects mobility, such as oxygen vacancies. This decreases the accumulation of the defects at domain boundary and reduces the domain pinning, resulting in easy switching of the ferroelectric domains.

Abstract:One of the problems in applying particle swarm optimization (PSO) is that the search process is sometimes biased by algorithm features such as the solution construction process. Due to such searching bias, PSO cannot converge to the optimal solution for some problems which are called deceptive problems. Taking the n-bit trap problem as an instance, we theoretically prove that PSO can not converge to the global optimal solution of such problem under certain conditions. In addition, we empirically verified the correctness of our theoretical conclusions. We also present an algorithm BS-sPSO for avoiding the searching bias. The algorithm BS-sPSO can change the particles' search direction and expand their search area at the appropriate time. Our experimental results on the n-bit trap problem show the effectiveness of our bias avoiding algorithm. © 2010 Binary Information Press.

Abstract:This paper put forward ideal geometry parameters of arch cylindrical gear based on analyzing the geometry parameters and process methods of similar arch cylindrical gears. It analyzed the mesh characteristics of two tooth surfaces of gear pair. By graphical representation of the tooth-surface equation and the mesh line expression, it demonstrated the mesh state of two teeth surfaces with graph, which can verify the feasibility of the gear's geometry parameters. It can be concluded that the radius of concave surface and convex surface of the tooth must be equal in the gear, the tooth thickness is equal to the slot width on the different radial section of the gear teeth and the pressure angle at the reference circle must be equal. Based on it, the processing method of the involute arch cylindrical gear and the parallel rod gear processing device, were put forward.

Abstract:The numerical simulation of internal flow and performance prediction of a variable speed mixed-flow pumping system are conducted by means of computational fluid dynamics, and the simulated pump performance parameters are compared with those converted by the similitude. The results show that variable speed operation of the pump affects the peak efficiency, and its maximum relative error of the conversion method under five speeds is 0.973%. When the pump runs off the peak efficiency, the error of conversion method decreases in the large flow-rate region, while increases in the small flow-rate region, with a maximum error of 3.043%. Under different pump speeds, the hydraulic characteristics of the outlet passage are not completely similar and the head losses at a given flow rate is not constant as a result of the outlet flow adjustment. These behaviors are the same as that of the mechanical, volumetric and hydraulic efficiencies of the pump. This is a possible explanation for the errors in the converted performance parameters by the similitude. © Copyright.

Abstract:A multi-agent system (MAS) has been built based on characteristics of emergency system, in which task schedulable and maximum task scheduling problem for the MAS has been discussed in our previous work. However, the mentioned task scheduling method both supposed that all tasks were equally important and agents have the same capability in playing a certain role, and evaluated the quality of task scheduling only by the number of accomplished tasks, which ignored the differences among tasks or Agents that conflicts with our real life. In order to make the task scheduling be more close to actual process of emergencies, the utility based optimal task scheduling problem (UOTSP) is proposed in this paper. The method assigns each task with a utility to represent the earnings from accomplishing it and adds preference on each Agent to distinguish the Agent's preferences and role play abilities. The UOTSP problem is proved to be NP complete by reducing MAX-S to it in polynomial time, and two approximate algorithms (GTS and RTOM) are proposed to solve the UOTSP problem approximately. The experiment results show that both GTS and RTOM can get excellent approximate solutions, and the time performance of GTS is wonderful which makes it suitable for the emergency applications of MAS (emergency system).

Abstract:Geographic routing is widely used in wireless sensor networks due to its great efficiency, good scalability and computed routing close to the best possible. However, the problem that geographic routing uses GPS receivers or location algorithms to obtain nodes' geographic information leads to expensive cost and high overhead. Aiming at this problem, we present a Landmark-based Virtual Geographic Routing Algorithm (LVGR), which depends only on node connectivity and not on any knowledge of node positions to discover the global topology of the sensor field. After topology discover, nodes can successfully communicate through local coordinate routing. Simulation shows that LVGR generates routes that are comparable to those generated by geographic routing algorithms, and even load-balanced. It has advantages in low cost, light routing overhead and high performance. © 2010 IEEE.

Abstract:In this paper, we propose a k-means algorithm which aims to find k biclusters for given gene expression data. Our algorithm k-Biclusters first clusters the columns (conditions) and groups the row (genes) in each subset of columns, then applies the row-clustering and column-clustering methods iteratively until the "steady" biclusters are found. After that, we refine the "steady" biclusters by reducing their Hscores and maximize the cluster size in the end. Experimental results demonstrate that the algorithm can efficiently find the co-regulation patterns, especially those highly homogenous with little difference from each other. © 2010 Binary Information Press.

Abstract:A modified cellular automata (CA) model of dynamic recrystallization (DRX) and a flow stress-based nucleation parameter identification method have been developed. In the method, the modified CA model, which takes the role of deformation degree on nucleation behavior into consideration, is coupled with an adaptive response surface model (ARSM) to search for the optimum nucleation parameter. The DRX behavior of an oxygen free high conductivity (OFHC) copper with different initial grain sizes has been taken as an example to validate the model. Good agreement is found between the simulated and the experimental results, which demonstrates that the new method can effectively improve the simulation accuracy. © 2010 The Chinese Society for Metals.

Abstract:In this paper, the operation O˙ and the concept of O˙-ideals of (regular) residuated lattices are introduced. Some characterization theorems for O˙-ideals of (regular) residuated lattices are given. Representation theorems about O˙-ideals which are generated by non-empty subsets of regular residuated lattices are obtained. For the set of all O˙-ideals of a (regular) residuated lattice, an adjunction pair is defined. It is proved that the lattice of all O˙- ideals in a regular residuated lattice with the adjunction and the set-inclusion order is a complete Heyting algebra (i.e., a frame) and an algebraic lattice, which thus gives a new distributive residuated lattice. © 2010 Springer-Verlag Berlin Heidelberg.

Abstract:This paper proposes the application of Gaussian process regression (GPR) as an alternative regression model to resolve the hard overlapped electrochemical signals belonging to the 2,4,6- trichlorophenol/2,6-dichlorophenol (TCP/DCP) system. Gaussian process derives from the perspective of Bayesian non-parametric regression methods, in terms of the parameterization of the covariance function, results in its good performance for the development of a calibration model for both linear and non-linear data sets. The multivariate regression model developed by GPR was compared with some traditional regression methods such as partial least squares regression (PLSR), and support vector regression (SVR). The comparative results were satisfied. The satisfactory results obtained throughGPR method suggest that it can be used as a more effective and promising tool for multivariate regression tasks than the others.

Abstract:Traditional Mining Frequent Pattems algorithms will construct lots of projected databases and generate lots of patterns with short length in the process of mining which cause the low efficiency of mining. In order to overcome the shortcomings of traditional algorithms, a fast and efficient algorithm SSPM was proposed. We used longer pattems for mining, which avoided producing lots of patterns with short length. We also used prefix tree of primary patterns for frequent patterns mining and pattern growth which could avoid producing plenty of irrelevant patterns .The experimental results show that SSPM not only improves the performance but also achieves effective mining results. © 2010 IEEE.

Abstract:Pattern recognition techniques have been widely used. In this paper, we propose an interpolation method for making classification decision (AIMMCD). This method makes an interpolation of the class labels of the patterns of the training set for classifying a new pattern. Compared with conventional pattern recognition techniques, AIMMCD has several advantages. First, when we use AIMMCD to produce the class label for the test pattern, no any training procedure. This means that AIMMCD to be computationally efficient. Second, when AIMMCD predicts the class label for real-world data, it takes into account the information of the class labels of all the patterns from the training set in a reasonable way. Indeed, the algorithm assumes that the training sample close to a pattern will have much influence on the class prediction of this pattern and the training sample far from this pattern will have little influence. Third, though AIMMCD has a very simple form, it is directly applicable to not only two-class problems but also multi-class problems. © 2010 IEEE.

Abstract:Closed-Loop Supply Chain(CLSC) contains several constituents whose operation time is different from each other, in order to improve the operation performance of CLSC, we need to learn the total operation time of CLSC. Therefore, it is imperative that CLSC's operation time should be analyzed. In this paper, Fuzzy graph theory is used to construct a time-consuming analysis model of CLSC. And the model consists of two parts, one is several level directions fuzzy graph which can describe relations among links of CLSC, and the other is the generalized fuzzy matrix which can measure the operation time of CLSC quantitatively. Lastly, an example of CLSC based on auto engine is analized. And the example shows the time-consuming analysis model of CLSC provides a foundation for improving CLSC's operation performance. © 2010 Binary Information Press.

Abstract:Based on the generalized coupled thermoelasticity in the Lord-Shulman (L-S) model, the state equation of infinite functionally graded plates were established by using of the Laplace transform and state space approach, in which the displacement, temperature and their first derivatives were chosen as state variables. As a numerical example, a functionally graded plate with the material properties changing by exponential law distribution along the thickness of plate, subjected to thermo-mechanical shock was considered. By employing the numerical inversion of the Laplace transform, numerical result showing the temperature, the displacement and stress components changing with the time are represented graphically. Characteristics of the propagation of the thermal elastic wave are also analyzed. © (2010) Trans Tech Publications, Switzerland.

Abstract:As a new kind of cylindrical gear, the involute arch cylindrical gear has preferable transmission characteristics, but its main geometry parameters have no unified standard. In this paper, the ideal geometry parameters of involute arch cylindrical gear are proposed and its tooth surface equation and meshing line equation are discussed. For verification, the computer graphics is introduced to show the meshing characteristics. By programming, tooth surface and meshing line are discretizesd, fetching some points and linking these points by short straight line to present the lines and surfaces which are visualized to show meshing characteristics. Simultaneously, a process way for arch cylindrical gears is proposed. © 2010 IEEE.

Abstract:Orthogonal Frequency Division Multiplexing (OFDM) has been focused on in high-data-rate wireless communication research. But the high Peak-to-Average Power Ratio (PAPR) is one of the main obstacles to limit wide applications of OFDM. In this paper, based on the definition of the PAPR in OFDM systems, these techniques on PAPR reduction are presented, including signal distortion, signal scrambling, and block coding. The related optimization problems as well as the advantages and disadvantages of these techniques are discussed in detail and some performances are achieved by Monte Carlo simulations. © 2010 Binary Information Press.

Abstract:Most of mining frequent subtree pattern algorithms generated lots of patterns with short length in the process of mining which caused the low efficiency of mining. To tackle these problems, we present IRTM, a top-down approach for mining frequent embedded subtrees on biological data. We also advance a string encoding method for representing the trees, and a scope-list for extending all substrings for frequency test. Experimental results show that IRTM algorithm can achieve significantly performance improvement over previous works. © 2010 Binary Information Press.

Abstract:Collaborative filtering has been proved to be one of the most successful techniques for building personalized recommendation systems. However, existing collaborative filtering algorithms have been suffering from data sparsity and scalability problems which lead to inaccuracy of recommendation. The calculation becomes more complex and time-consuming when the users and items in ratings database increase quickly. To solve these problems, this article proposes a collaborative filtering recommendation algorithm based on item clustering prediction by combining items attributes and their ratings properly for similarity computing. Firstly, all the items are clustered according to the similarity integrating their attributes and users' ratings. Then clusters with high similarity to target item are selected as the candidate set, from which the nearest neighbors would be found. Finally the current user's rating for the target item would be predicted according to the weighted average ratings of the neighbor. The experimental results show that our algorithm can improve the recommendation quality and enhance the system real-time performance effectively. © 2010 Binary Information Press.

Abstract:Constellation networking is the prominent technology for the next generation satellite systems. The communication schedule is a key problem for constellation maintenance. However, the traditional SRS (Satellite Range Scheduling) model do not use inter-satellite links. In this paper, a communication scheduling model is proposed, in which the ISLs (Inter Satellite Links) is built. And the NP complicity of SNRS is proved. Meanwhile, a two stage greedy algorithm is designed to calculate the SNRS. And heuristic strategies in the proposed algorithm are compared by simulation. The experiment results show that EDF strategy combined with minimum distance route can bring into an acceptable schedule. © 2010 IEEE.

Abstract:The asymmetry of the magnetization reversal strongly depends on the angle between the easy axis of the FM or AFM and the applied field. Different angle reveals different reversal process. However, in the exchange-bias systems with different ferromagnetic(FM) magnetization revealing under small FM anisotropy a reorientation of the effective anisotropy occurs due to a new noncollinear for anisotropy term, which is unambiguously induced from interface exchange coupling between FM and anti-ferromagnetic layer.[1] We display evidence of the relation between noncollinear anisotropics of the FM anisotropy and interface exchange coupling and asymmetric magnetization reversal. © 2010 IEEE.

Abstract:In order to solve objective granularity in some microscopy images, an algorithm for de-noising and granularity calculation based on mathematical morphology is proposed. Square and circular structure elements are presented, which are used to image preprocessing and granularity detection process. The different de-noising effects by using the two structure elements were gotten. Moreover, given only one kind of structure elements, after we changed the size of the structure element, the differences of de-noising effects are very apparent. By using two-dimensional structure elements, the granularity detection and calculation is compared with that in the case of one-dimensional direction. The range of detected granules' size and shape can be expanded. Meanwhile, the use of mathematical morphology to a certain extent overcomes the interference of noise. Taking one parasite egg image as a simulation example, we detected granularity by using different structure elements, experimental results show that the image granularities have great difference, and two-dimensional detection is better than one-dimensional direction detection obviously. © 2010 Binary Information Press.

Abstract:Post-buckling of functionally graded material Timoshenko beams with surface-bonded piezoelectric layers subjected to temperature rise and electric field is studied. By accurately considering the axial extension and transverse shear deformation in the sense of theory of Timoshenko beam, geometrically nonlinear governing equations, for functionally graded beams subjected to thermo-electro-mechanical loadings were formulated. In the analysis, it was assumed that the material properties of the beam vary continuously as a power function of the thickness coordinate and that the piezoelectric layers are isotropic and homogenous. By using a shooting method, the obtained nonlinear boundary value problem was numerically solved and buckling and post-buckling response of the beams with the both ends fixed and subjected to transversely non-uniform heating and uniform electric field were presented. Characteristic curves of the post-buckling deformation of the beam varying with thermal load, the electrical load, and the power law index are plotted. Numerical results show that the tensional force produced in the piezoelectric layers by the voltage can efficiently increase the critical buckling temperature and defer the thermal post-buckling to occur. Due to being transversely non-uniform in the material properties, there exists tension-bending coupling effects in the beam even in uniform temperature rise in the thickness direction. However, for the piezoelectric-FGM beam with the two ends fixed the post-buckling is also bifurcation form under transversely non-uniform temperature rise.

Abstract:A single product closed-loop supply chain that satisfies an uncertain market demand with original and remanufactured products is considered. The yield of the recovery process is random and depends on the acquisition price offered for the end-of-life products. In such a stochastic setting, a firm needs to make production and procurement decisions so that the total expected profit is maximized. Both centralized and decentralized models are established depending on the party collecting the returns. The optimal acquisition price and production quantities of original and remanufactured products are determined for the firm. The contracts to coordinate the decentralized systems are chosen and the optimal contract parameters are determined. A computational experiment is given to show the effects of recovery parameters on the system performance. Results show that the recovery parameters have a high impact on the profitability of the manufacturer in the centralized model and on that of the collection agency in the decentralized model. © Copyright.

Abstract:A blind digital watermarking algorithm based on chaotic is proposed. Logistic system is used to generate chaotic sequence, which is binarizated in the following step. Then one-dimensional binary Logistic sequences are changed into two-dimensional matrix through inverse Zigzag scanning, which is XOR encrypted with the original watermark. Turn the original color image to the YCbCr color spaces, and decompose Y component by 2-layer wavelet. Then the new relationship among the chosen wavelet coefficients can be built using the chaotic matrix. Consequently, the watermark is embedded into the low frequency wavelet coefficients based on this relationship. During watermark extraction, the relationship can be obtained by the same algorithm. Finally, the modified wavelet coefficients are applied to replace the original wavelet coefficients, and we can obtain the image component containing watermark, then with the other two color components, which are color-space changed into the RGB space. The image with watermark is gotten. Therefore, the original watermark can be extracted without original image. The experimental results indicate that, compared with other algorithms, the robustness is stronger while the computation complexity is lower, but the transparency is comparatively inferior. © 2010 IEEE.

Abstract:Mesoporous silica materials with well-ordered hexagonal structure were synthesized under acidic conditions. The influences of crystallization conditions, aging conditions, acid sources HX and acid/ tetraethyl orthosilicate ratio on the order degree and the morphology have been discussed. The increase of crystallization temperature or crystallization time was beneficial for the condensation of silica species, but had no effect on improving the order degree of mesoporous silica. The order degree of mesoporous materials using various acid sources HX under the same acid concentration swas as follows: HNO 3>HBr> H2SO4>HCl which differed from that in the Hofmeister series; the sulfate anions 24 SO2-4 can play a supporting role on pore structure in the form of space occupation, leading to forming more ordered products than in HCl. Besides, the NO 3¯ and Br¯ions showed contrary effect on the growth of micelles, the bigger the pore wall thickness we obtained, the less HBr or the more HNO3 we used.

Abstract:The computational fluid dynamics (CFD) method is used to investigate the three-dimensional(3D) flow fields in a postpositional bulb tubular pump. In the numerical modeling, RNG k-Ε turbulence model and SIMPLE algorism are employed. The velocity distribution and pressure of vertical plane at BEP are analyzed, as well as the velocity of impeller outlet, guide-vane outlet and the tail of the bulb. The focus is on the static pressure distribution of blade pressure surface and suction surface as well as the relative velocity distribution near the airfoil cross-sections under different conditions (the designed condition, large and small flow rates conditions). The hydraulic losses of various components of tubular pump are also calculated, and it is found that the guide vane and bulb unit occupy major share in hydraulic losses. The comparison between the mathematical model calculation result and the model-tested pump performance data shows that the calculation result agrees well with the test data in nearby the high efficiency area; however, deviation exists between them under large flow and small flow working conditions. Using CFD method to simulate the internal flow field of tubular pump can provide the basis for further design optimization of the tubular pump. © 2010 Journal of Machanical Engineering.

Abstract:By using semi-analytical method, elastic stability of a simply supported FGM sandwich circular cylindrical shell under torsion loading was studied. The inner and outer layers of the shell are comprised of the same homogeneous and isotropic material, and the middle layer is made of an isotropic functionally graded material whose properties varies continuously in the thickness direction from the inner layer to the outer layer, and keeps continuation in the material properties of the interface. Firstly, based on the Flu¨gge thin shell theory, the governing equations for static buckling of the structure in terms of displacements were formulated. Secondly, by introducing the displacements in terms of trigonometric functions that identically satisfy the boundary conditions, an eigenvalue problem for linear algebraic equations including the torsion force parameter is obtained. Finally, critical buckling load characterizing the features of instability of the structure were obtained by numerical method. The numerical results show that the buckling load decreases with an increases in the radius to thickness ratio, and increases with an increase in the average value of Young's modulus of the FGM middle layer.

Abstract:A novel glucose biosensor was achieved by casting the biocomposite on the surface of platinum disk electrode via the cross-linking step by glutaraldehyde, with the laboratory-prepared bismuth oxide nanoparticles as enzyme immobilization matrix. The modified electrode has been characterized by scanning electron microscopy (SEM), infrared spectroscopy (IR) and electrochemical impedance (EIS) etc. SEM shows that the prepared nano-bismuth oxide is composed by two-dimensional nano-bismuth oxide sheet and one-dimensional nano-rod. The nano-bismuth oxide sheet thickness is about 80 to 110 nm with sub-micron-micron-level horizontal dimensions, and the diameter of bismuth oxide nanorods is about 40 to 50 nm. Experimental results show that the optimal conditions to fabricate biosensor are: GOD and BiOx mass ratio of 2:1, enzyme immobilized amount of 30 μg. The pH and the detection potential effects were also investigated. The biosensor has a wide linear range from 1 × 10-3 to 1.5 mmol/L with detection limit of 0.4 mmol/L (SNR=3) at 0.5 V vs. SCE. The apparent Michaelis constant is 2.88 mmol/L. And the biosensor presents fast response (5 s), good repeatability and excellent long-term stability.

Abstract:Cereal starch granules with high-amylose and resistant starch (RS) always show irregular morphology and special crystalline structure, but their formation during grain development is not yet clear. In our previous studies, we had generated a transgenic rice line (TRS) enriched with amylose and RS, which contained semi-compound starch showing a C-type crystalline structure. In this study, the formation of semi-compound C-type starch granule during TRS endosperm development was carefully investigated with light, scanning electron, and transmission electron microscopes and X-ray powder diffraction. The results showed that the TRS starch subgranules, each with a central hilum, were individually initiated in amyloplast and showed an A-type crystal at the early stage of starch granule development, which was similar to that in its wild type. However, with the endosperm development, the amylose content in TRS endosperm starch increased and the B-type starch crystal was deposited in the periphery of subgranules; then, the adjacent subgranules fused together and finally formed a continuous outer layer band surrounding the entire circumference of the starch granule. Accordingly, a mechanistic model for the formation of semi-compound C-type starch granules is proposed. © 2010 American Chemical Society.

Abstract:Pure nano-Fe3O4 and cobalt-doped nano-Fe 3O4 particles are successfully synthesized by co-precipitation method using tetramethylammonium hydroxide (TMAOH) as alkali. Several key factors that may affect preparation are carefully discussed such as alkali concentration, alkali dosage, reaction temperature, iron salt solution concentration and dispersant agents. Such nano-Fe3O4 particles prepared have good dispersibility and a very narrow size distribution with the average diameter about 38 nm, which are proved to be cubic spinel Fe3O4 crystal by XRD pattern. It is also found that the addition of PEG-4000 surfactant can improve the dispersibility of nanoparticles. In our work, effects of cobalt dopant concentration on magnetic properties of cobalt-doped nano-Fe3O4 are also discussed. The result shows that the coercivity of cobalt-doped nanoparticles changes greatly with the variation of cobalt dopant concentration. The maximum coercivity reaches as high as 1628 Oe, which is very meaningful for preparation of materials with high coercivity. © 2010 World Scientific Publishing Company.

Abstract:The hole spin accumulation and spin-polarized transport in ferromagnetic semiconductor (FS) /d -wave superconductor (SC)/FS tunnel junctions with {110} interfaces are studied by using four-component Bogoliubov-de Gennes equations, in which the Andreev reflection and four-subband model for the FS are taken into account. It is found that due to the interplay of the d -wave SC and FS, the nonequilibrium hole spin accumulation, differential conductance, and tunneling magnetoresistance exhibit a rich dependence on the Andreev reflection, strengths of potential scattering at the interfaces, mismatches in the effective mass and band between the FS and SC, and types of incident holes, which is much different from that in FS/s -wave SC/FS tunneling junctions. Particularly, it is demonstrated that the differential conductance can be negative in both ferromagnetic and antiferromagnetic alignments for not only incident heavy holes but also incident light holes, and the variations in both the energy gap with temperature and hole spin accumulation with bias voltage can display a twofold behavior due to the Andreev reflection. © 2010 American Institute of Physics.

Abstract:Ordered mesoporous silica was successfully synthesized by using mixed surfactants, cetyltrimeth-ylammonium bromide and sodium dodecylsulfate, proceeded with the hydrolysis and condensation of tetra-ethyl orthosilicate in a mixture of TritonX-100 as a cosolvent. The synthesized products were characterized by X-ray diffraction patterns (XRD), scanning electron microscopy (SEM), transmission electron micros-copy (TEM), and nitrogen sorption analysis. It was found with increasing the anionic surfactant sodium dodecylsulfate to cetyltrimethylammonium bromide molar ratio, the morphologies of mesoporous silica changed from spherical shape to ellipsoidal shape, at last became rod-like and lamellar shape. Correspondingly the pore diameter and surface area of mesoporous silica all decreased according to nitrogen sorption analysis. The TEM analysis illustrated the product with ordered hexagon mesostructure and homogeneous pore arranged can be obtained, when the molar ratio of cetyltrimethylammonium bromide/sodium dodecylsulfate is 15 : 1. It also demonstrated the less the molar ratio of sodium dodecylsulfate was used, the more ordered pore structure the products exhibited. Furthermore, prolonging the crystal time was beneficial to improve the stability of the product. © Pleiades Publishing, Ltd., 2010.

Abstract:Poly(isin;-caprolactone)/polylactide blend (PCL/PLA) is an interesting biomaterial because the two component polymers show good complementarity in their physical properties. However, PCL and PLA are incompatible thermodynamically and hence the interfacial properties act as the important roles controlling the final properties of their blends. Thus, in this work, the PCL/PLA blends were prepared by melt mixing using the block copolymers as compatibilizer for the studies of interfacial properties. Several rheological methods and viscoelastic models were used to establish the relations between improved phase morphologies and interfacial properties. The results show that the interfacial behaviors of the PCL/PLA blends highly depend on the interface-located copolymers. The presence of copolymers reduces the interfacial tension and emulsified the phase interface, leading to stabilization of the interface and retarding both the shape relaxation and the elastic interface relaxation. As a result, besides the relaxation of matrices (τrn) and the shape relaxation of the dispersed PLA phase (τF), a new relaxation behavior (τβ) which is attribute to the relaxation of Marangoni stresses tangential to the interface between dispersed PLA phase and matrix PCL, is observed on the compatibilized blends. In contrast to that of the diblock copolymers, the triblock copolymers show higher emulsifying level. However, both can improve the overall interfacial properties and enhance the mechanical strength of the PCL/PLA blends as a result. © 2010 Wiley Periodicals, Inc.

Abstract:We propose a method for recognition of most important subgraphs in collaboration networks. The networks can be described by bipartite graphs, where basic elements, named actors, are taking part in events, organizations or activities, named acts. It is suggested that the subgraphs can be described by so-called k-cliques, which are defined as complete subgraphs of two or more vertices. The k-clique act degree is defined as the number of acts, in which a k-clique takes part. The k-clique act degree distribution in collaboration networks is investigated via a simplified model. The analytic treatment on the model leads to a conclusion that the distribution obeys a so-called shifted power law P(q) ∝ (q + α) where α and γ are constants. This is a very uneven distribution. Numerical simulations have been performed, which show that the model analytic conclusion remains qualitatively correct when the model is revised to approach the real world evolution situation. Some empirical investigation results are presented, which support the model conclusion. We consider the cliques, which take part in the largest number of acts, as the most important ones. With this understanding we are able to distinguish some most important cliques in the real world networks. © 2009 ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.

Abstract:in this paper, the stabilization problem is considered for a class of nonlinear continuous stochastic systems with state delays. The purpose of this problem is to design a state feedback controller such that the closed-loop system is exponentially stable (or exponentially ultimately bounded) in the mean square, for all admissible nonlinearities and time-delays. We first investigate the sufficient conditions for the nonlinear stochastic time-delay systems to be stable, and then derive the explicit expression of the desired controller gains. A numerical simulation example is provided to show the usefulness of the proposed design method. Copyright © 2005 IFAC.

Abstract:The effect of poling on the switching properties of SrBi2Ta 2O9 films was investigated via the technique of switching current testing. The samples with 660 nm thickness were poled under dc voltage ranging from 1 to 8.25 V, and for different duration from 1 to 80 min. After poling, both the net-switched charge and switching time first jumped to higher values, then decreased with the elapse of time. The decreases were separated into two regimes, a fast and slow regime. The change of net-switched charge and switching time with poling voltage and poling time showed nonmonotonic behavior. These results were explained by the change of domain kinetics and the redistribution of charge carriers under both the applied and depolarization field. © 2002 American Institute of Physics.

Abstract:SrBi4Ti4O15 (SBTi) and Bi-excess and Sr-deficient SBTi (Sr-deficient SBTi, Sr0. 8Bi4. 13Ti 4O15) thin films were deposited on Pt/Ti/SiO 2/Si (100) substrates using a sol-gel method. Structure and electric properties were investigated systematically. These films were random oriented. The remnant polarization (2Pr) of SBTi film was about 25.3 &C/cm 2, which was larger than the reported value of SBTi thin film. The film with Sr-deficient and Bi-excess composition showed a very large remnant polarization of 36.6 lC/cm2. The capacitance-voltage (C-V) characteristics of both the films showed normal ferroelectric behavior. The Curie temperatures of the same Sr-deficient and Bi-excess component ceramics sample increased slightly in comparison with that of SBTi. More importantly, the Sr-deficient and Bi-excess SBTi thin film showed high fatigue resistance against continuous switching up to 4.4 9 1010 cycles. © Springer Science+Business Media, LLC 2010.

Abstract:The indica rice cultivar, Teqing, shows a high level of resistance to rice stripe virus (RSV). It is believed that this resistance is controlled by the gene, qSTV11TQ. For positional cloning of the resistance gene, a set of chromosome single segment substitution lines (CSSSLs) was constructed, all of which had the genetic background of the susceptible japonica cultivar, Lemont, with different single substituted segments of Teqing on chromosome 11. By identifying the resistance of the CSSSLs-2006 in a field within a heavily diseased area, the resistance gene qSTV11TQ was mapped between the markers Indel7 and RM229. Furthermore, in that region, six new markers were developed and 52 subregion CSSSLs (CSSSLs-2007) were constructed. The natural infection experiment was conducted again at different sites, with two replicates used in each site in order to identify the resistance phenotypes of the CSSSLs-2007 and resistant/susceptible controls in 2007. Through the results of 2007, qSTV11TQ was localized in a region defined by the markers, CAPs1 and Indel4. In order to further confirm the position of qSTV11TQ, another set of subregion CSSSLs (CSSSLs-2009) was constructed. Finally, qSTV11TQ was localized to a 55.7 kb region containing nine annotated genes according to the genome sequence of japonica Nipponbare. The relationship between qSTV11TQ and Stvb-i (Hayano-Saito et al. in Theor Appl Genet 101:59-63, 2000) and the reliability of the markers used on both sides of qSTV11TQ for marker-assisted breeding of resistance to rice stripe disease are discussed. © 2010 Springer-Verlag.

Abstract:By introducing a homogeneous piezoelectric material and its Green's function, we present a new semi-analytical three-dimensional perturbation method for general inhomogeneity problems in anisotropic and piezoelectric solids. This method removes the limitations associated with previous analytical methods, which often ignore the anisotropic properties or the difference between the material properties of the inhomogeneity and its surrounding matrix. As an important application, the proposed theory is employed to calculate the elastic and electric fields in a truncated pyramidal InAs/GaAs quantum-dot (QD) nanostructure. Numerical results demonstrate that the anisotropy of the materials and the difference between the material constants of the QD and the matrix have a significant influence on the strain and electric fields. The relative differences of the strain and electric field inside the QD between the simplified isotropic and homogeneous model and the real anisotropic and heterogeneous one may reach 22% and 53%, respectively. The accuracy of the calculated elastic strain and electric fields is improved greatly by a second order approximate solution (OAS). Since the third OAS nearly coincides with the second one, good convergence of the iteration procedure is demonstrated. Moreover, contours of the hydrostatic strain and electric potential within and around the QD are also presented and analyzed. © 2010 Elsevier Ltd. All rights reserved.

Abstract:Single-walled carbon nanotubes (SWCNTs) functionalized with carboxylic acid groups were cast to glassy carbon electrode (GCE) to construct a three-dimensional nano-micro structured scaffold. Brilliant cresyl blue (BCB) was electropolymerized on the above-mentioned SWCNTs/GCE using continuous cycling between -0.7 and 0.9 V vs. SCE. PolyBCB yielded on SWCNTs/GCE exhibited the enhanced electrochemical redox behavior compared with that electrogenerated on bare GCE. The apparent surface coverage of PolyBCB obtained by SWCNTs/GCE was at least 10 times higher than that obtained by bare GCE, namely 4.8 × 10-9 and 3.6 × 10-10 mol cm-2. The cyclic voltammograms recorded by PolyBCB/SWCNTs/GCE exhibited well-defined two peaks located at -0.25 V and -0.06 V, respectively, with a surface-controlled mechanism. In addition, morphologies of PolyBCB electrogenerated on GCE and SWCNTS/GCE were characterized by atomic force microscopy. Finally, this proposed PolyBCB/SWCNTs/GCE was used in the construction of the second-generation biosensors to hydrogen peroxide and glucose, with the enhanced analytical performance. © 2010 Elsevier B.V.

Abstract:The cycloaddition reactions of N-heterocyclic silylenes 1-4 with ethylene (C2H4) and formaldehyde (CH2O) molecules were performed at the MP2/6-31G** level of theory, respectively. Full optimizations and frequency analyses were done for the stationary points on the potential energy surface. The intrinsic reaction coordinate (IRC) was also calculated for all the transition states at the same level of theory. The possible cycloaddition mechanisms were investigated and results from various reactions were compared in detail. The theoretical results indicated that the cycloaddition reactions of N-heterocyclic silylenes with C2H 4 and CH2O proceeded through a concerted mechanism to form a three-membered ring containing C1, C2 (O), and Si atoms in the products, which was similar to those of simple silylene H2Si. Silylenes 1-4 exhibit some electrophilicity toward C2H4 whereas nucleophilicity toward CH2O leading to the reaction process. Based on the reaction energy barrier and the exothermic energy, the reaction activities of saturated silylene (2) were stronger than those of unsaturated silylenes (1, 3, and 4). © 2010 Elsevier B.V.

Abstract:Photoperiod-thermo-sensitive genic male sterile (PTGMS) rice exhibits a number of desirable traits for hybrid rice production. The cloning genes responsible for PTGMS and those elucidating male sterility mechanisms and reversibility to fertility would be of great significance to provide a foundation to develop new male sterile lines. Guangzhan63S, a PTGMS line, is one of the most widely used indica two-line hybrid rice breeding systems in China. In this study, genetic analysis based on F2 and BC1F2 populations derived from a cross between Guangzhan63S and 1587, determined a single recessive gene controls male sterility in Guangzhan63S. Molecular marker techniques combined with bulked-segregant analysis (BSA) were used and located the target gene (named ptgms2-1) between two SSR markers RM12521 and RM12823. Fine mapping of the ptgms2-1 locus was conducted with 45 new Insertion-Deletion (InDel) markers developed between the RM12521 and RM12823 region, using 634 sterile individuals from F2 and BC1F2 populations. Ptgms2-1 was further mapped to a 50.4 kb DNA fragment between two InDel markers, S2-40 and S2-44, with genetic distances of 0.08 and 0.16 cM, respectively, which cosegregated with S2-43 located on the AP004039 BAC clone. Ten genes were identified in this region based on annotation results from the RiceGAAS system. A nuclear ribonuclease Z gene was identified as the candidate for the ptgms2-1 gene. This result will facilitate cloning the ptgms2-1 gene. The tightly linked markers for the ptgms2-1 gene locus will further provide a useful tool for marker-assisted selection of this gene in rice breeding programs. © Springer-Verlag 2010.

Abstract:The poly(bromothymol blue) film was prepared using a simple cyclic voltammetry method. Field emission scanning electron microscopy and electrochemical methods were employed to characterize this film. When the film was electropolymerized on an electrode, it showed excellent catalytic activity toward the oxidation of dopamine (DA) in pH 4.0 phosphate buffer solution. In addition, the overlapped voltammetric responses of dopamine and ascorbic acid were resolved into two well-defined peaks by the film-modified electrode with a large peak separation of 0.17 V. A calibration curve for DA was obtained by the amperometric method in the range of 3.0-195.0 μM with a correlation coefficient of 0.9997. The film-modified electrode has been successfully used to measure the concentration of DA in injections and human serum samples. © 2010 Springer Science+Business Media B.V.

Abstract:Monodispersed hybrid silica spheres with particles sizes up to 4 μm were obtained by controlling the number of nuclei generated in the initiation phase of particle formation using a two-step sol-gel method. This method has two advantages: (i) the particle size can be tuned easily just by variation of the amount ammonia added in the step of precursor hydrolysis, and (ii) the amount of precursor used to prepare particles with the same diameter is at least ten times lower than with traditional methods. The effects of stirring speed and stirring time on the resulting particle size were also studied. © 2010 Elsevier B.V. All rights reserved.

Abstract:With water droplets as sacrificed templates at a particular humidity, micro-porous solid thin films were successfully fabricated by self-assembly using an amphiphilic block polymer, polystyrene-b-polyacrylic acid (PS-b-PAA). Interface interactions between the micro-porous thin film and a cationic surfactant, cetyltrimethylammonium bromide (CTAB), are investigated by in-situ AFM in aqueous solutions. An interesting phenomenon was observed in water and CTAB solution, which the dimensions of the micropores are remarkably larger than the dimensions of those in air. The solid thin films exhibit different surface morphologies in response to stimulus by different concentrations of CTAB. These observations were explained by positing that the PAA chains in the micropores stretch and contract with interface interactions between PAA and CTAB. A promising electrochemical application of this film is suggested. This study is aimed at strategies for the functionalization of stimulus-responsive micro-porous solid thin films with tunable surface morphologies, and exploring new smart materials. © 2010 Elsevier Inc.

Abstract:The purpose of this study was to investigate associations between pyrethroids occupational exposures, and risk of abnormal glucose regulation. Data from total of 3080 subjects in two pesticide factories were used. This was a population-based case-controlled study in China. In total, 18.3% of subjects with impaired glucose regulation (IGR) and 6.5% of subjects with diabetes, and the prevalence of abnormal glucose regulation was 24.8%, 86 subjects had known type 2 diabetes and 114 had newly diagnosed diabetes. The prevalence of subjects with abnormal glucose regulation increased from 21.3% in the controls to 29.3% in the exposures (χ2=33.182, P<0.001). Multivariate logistic regression was used to control potential confounders and calculate odd ratios as the estimate of effect. An indication of increased risk for abnormal glucose regulation was noted for exposure to pyrethroids (OR=1.482, 95%CI=1.238-1.774). Abnormal glucose regulation is common in subjects exposed to pyrethroids. The present investigation indicates the adverse health effects of pyrethroids are underestimated. © 2010 Elsevier Ltd.

Abstract:Rod-like hydroxyapatite (HAp) nanoparticles with various aspect ratios are synthesized by means of low-temperature hydrothermal method in the presence of a N-[(2-hydroxy-3-trimethylammonium) propyl]chitosan chloride (HTCC) template. The synthesized HAps were examined by X-ray diffraction (XRD), Fourier transform infrared spectrophotometer (FTIR) and transmission electron microscopy (TEM) techniques. The results reveal that HAps are rod-like monocrystals, where the size and morphology can be tailored by varying synthesis conditions, such as pH, hydrothermal synthesis temperature and the ratio of PO43- to the quaternary ammonium in HTCC. The mechanism of HTCC template on HAp nanorod preparation is analyzed. © 2010 Elsevier B.V. All rights reserved.

Abstract:In this paper, the cooperating two-species LotkaVolterra model is discussed. The existence and asymptotic behavior of T-periodic solutions for the periodic reaction diffusion system under homogeneous Dirichlet boundary conditions are first investigated. The blowup properties of solutions for the same system are then given. It is shown that periodic solutions exist if the intra-specific competitions are strong whereas blowup solutions exist under certain conditions if the intra-specific competitions are weak. Numerical simulations and a brief discussion are also presented in the last section. © 2010 Published by Elsevier Ltd. All rights reserved.

Abstract:Monodisperse samarium-doped ceria nanocrystals have been rapidly synthesized by a microemulsionmediated hydrothermal method with secondary light irradiation treatment. The microemulsion system consists of cetyltrimethyl ammonium bromide and n-butanol and n-octane, acting as the surfactant, cosurfactant and oil phase, respectively. The as-synthesized nano powder is characterized by well-dispersed rhombohedral particles with their size in the range of 75 to 85 nm. The results demonstrate that it could effectively inhibit coarsening and agglomeration of the product nanocrystals during the phase formation process by using the light irradiation treatment instead of conventional heat treatment. © 2010 Elsevier B.V.

Abstract:The adsorbents of starch grafted p-tert-butyl-calix[4,6,8]arene-SGCn (SGC4, SGC6, SGC8) are prepared. The products are characterized by FTIR, elemental analysis, thermal gravimetric analysis and scanning electron microscope. Static adsorption behavior is studied by using SGC8 as adsorbent, butyl Rhodamine B (BRB) solution as simulation dye wastewater. The adsorption of BRB onto SGC8 fits the second order kinetic model and the apparent adsorption rate constant is 0.002gmg-1min-1 at 25°C. The equilibrium adsorption data are interpreted using Langmuir and Freundlich models. The adsorption of BRB onto SGC8 is better represented by the Langmuir equation. The thermodynamic parameters for the adsorption reaction are calculated through van't Hoff analysis. The adsorbent may be easily regenerated by using ethanol solution as desorption agent to extract dye from SGC8. The rate of desorption of BRB is dependent on the concentration of ethanol and the temperature. SGC8 exhibits excellent adsorption and desorption properties toward dye molecule. The new-style adsorbent of SGC8 is regarded as a potential adsorbent to deal with dye or organic wastewater. © 2010 Elsevier B.V.

Abstract:Na-doped ZnO nanowires with an average diameter of ~. 40. nm have been fabricated by a thermal decomposition route at temperatures around 400°C. Their properties have been investigated using X-ray diffraction, field emission scanning electron microscope, Raman spectra, photoluminescence spectra and X-ray photoelectron spectra. Photoluminescence spectra showed that the as-synthesized ZnO samples exhibited strong visible emission with a major peak at 420. nm. Furthermore, intensity of the visible emission at 420. nm enhanced as the increase of Na concentration. The improvement of visible emission in the Na-doped ZnO samples should be a result of the surface defects increased by doping of Na in ZnO. Their antibacterial activities were also evaluated by determination of minimum inhibitory concentration (MIC) against Escherichia coli 25922 in vitro. Antibacterial tests indicated these nanomaterials showed good antibacterial properties after UV illumination for a short time. © 2010 Elsevier B.V.

Abstract:Water and a geranyl acetate solution of a non-ionic surfactant, a commercial C12EO4, were brought into contact in amounts to give a combination of a lamellar liquid crystal and an oil phase of equal weights at equilibrium and the equilibration transport between the layers was followed by measuring the change in layer heights with time. The initial reaction, lasting approximately two months, transferred surfactant from the oil phase to combine with water to form a birefringent layer initially containing excess water over the fraction in the liquid crystal in equilibrium with both water and oil phase. After this period the composition of the oil phase had reached a level corresponding to equilibrium with both water and a lamellar liquid crystal, while the birefringent phase, although a liquid crystal, still contained less water fraction than required for equilibrium. The final equilibration process of transferring the excess water to the formed liquid crystal was extremely slow with an estimated time to reach equilibrium of several years. © 2010 Elsevier B.V.

Abstract:A chemical bath deposition method has been proposed for the preparation of SnS2 thin films onto glass slides from the aqueous solutions of tin (IV) chloride pentahydrate, thioacetamide and citric acid at 35°C. High quality SnS2 thin films were obtained by adjusting the amounts of citric acid, which was used here as a complexing agent. The as-prepared thin films were characterized by Raman spectra, field emission scanning electron microscopy (FESEM), surface profiler and UV-vis absorption spectra. Raman spectra revealed that the as-prepared films were of hexagonal phase SnS2. FESEM images and surface profiler measurements indicated that the SnS2 thin film deposited under the optimum condition was homogeneous and well adhered to the substrate, with a thickness of about 200 nm. Optical absorption measurements disclosed that the SnS2 thin film deposited under the optimum condition had a band gap of about 2.40 eV. © (2011) Trans Tech Publications.

Abstract:A sub-picomole level topotecan hydrochloride determination method was first proposed using sodium dodecyl sulfate (SDS) as a sensitized reagent at a novel disposable electrode (an improved wax-impregnated graphite electrode). The effects of different kinds of surfactants on the electrochemical response to topotecan hydrochloride were examined. The results indicate the electrochemical signal was apparently improved by SDS. At optimal conditions, the oxidative peak current increased linearly with the logarithm of concentrations for topotecan hydrochloride in the ranges of 2.0 × 10-12 to 1.0 × 10-11 mol/L and 8.0 × 10-11 to 8.0 × 10 -10 mol/L with a detection limit of 6.4 × 10-13 mol/L. The proposed method could be applied in determining topotecan hydrochloride in urine. © 2010 Science China Press and Springer-Verlag Berlin Heidelberg.

Abstract:The characteristics of host-guest complexation between water-soluble calix[n]arenesulfonates (CnS, n = 4, 6, 8) and butyl rhodamine B (BRB) were investigated by fluorescence spectrometry. Fluorescence spectroscopy experiments were performed in pH 8.0 Tris(3-aminomethane)-HCl buffer solution at different temperature to calculate the stability constants (KS) for the stoichiometric 1:1 inclusion complexes of C4S, C6S, and C8S with BRB. The complex stability constant monotonically increased with the number of phenolic units in the calixarene ring. The thermodynamic parameters at T = 298 K for the inclusion complexes were calculated through Van't Hoff analysis. The inclusion complexes of CnS with BRB were driven by the favorable enthalpic changes, accompanying negative entropy changes. The stability constants were affected by the acidity of the solution. When pH was 8.0, the stability constants reached the maximum. The complex interaction was mainly attributed to the weak forces including electrostatic interaction and hydrogen bonding. © 2010 Elsevier Ltd. All rights reserved.

Abstract:Starch paste viscosity plays an important role in estimating the cooking, eating, and processing quality of rice. The inheritance of starch paste viscosity in glutinous rice remains undefined. In the present study, 118 glutinous rice accessions were collected, and the genotypes of 17 starch synthesis-related genes (SSRG) were analyzed by using 43 gene-specific molecular markers. Association analysis indicated that 10 of 17 SSRGs were involved in controlling the rapid visco analyzer (RVA) profile parameters. Among these, the PUL gene was identified to play an important role in control of peak viscosity (PKV), hot paste viscosity (HPV), cool paste viscosity (CPV), breakdown viscosity (BDV), peak time (PeT), and paste temperature (PaT) in glutinous rice. Other SSRGs involved only a few RVA profile parameters. Furthermore, interactions between SSRGs were found being responsible for PeT, PaT, and BDV. Some of the RVA parameters, including PKV, HPV, CPV, CSV, and PaT, were mainly governed by single SSRG, whereas other parameters, such as BDV, SBV, and PeT, were controlled by a few SSRGs, functioning cooperatively. Further, three near-isogenic lines (NIL) of a japonica glutinous cv. Suyunuo as genetic background, with PUL, SSIII-1, and SSIII-2 alleles replaced with those of indica cv. Guichao 2, were employed to verify the genetic effects of the various genes, and the results were consistent with those obtained from the association analysis. These findings indicated that starch paste viscosity in glutinous rice had a complex genetic system, and the PUL gene played an important role in determining the RVA profile parameters in glutinous rice. These results provide important information for potentially improving the quality of glutinous rice. © 2010 Springer-Verlag.

Abstract:The use of furazolidone in food animals has been banned in European Union (EU) because of its carcinogenicity and mutagenicity on human health, but its continued misuse is widespread. Therefore, there is an urgent need for a simple, reliable, and rapid method for the detection of its marker residue, 3-amino-2-oxazolidinone (AOZ), in food products. In this regard, a sensitive and reliable electrochemical method was presented to detect AOZ based on a novel label-free electrochemical impedimetric immunosensor to address this need. The immobilization of monoclonal antibody against AOZ (denoted as AOZ-McAb) on the gold electrode was carried out through a stable acyl amino ester intermediate generated by 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) and N-hydrosuccinimide (NHS), which could condense antibodies on the self-assembled monolayer (SAM). The detection of AOZ was performed by measuring the relative change in charge transfer resistance before and after AOZ and AOZ-McAb immunoreaction by electrochemical impedance spectroscopy (EIS). Under the optimized conditions, the relative change in charge transfer resistance was proportional to the logarithmic value of AOZ concentrations in the range of 20.0 to 1.0×104ngmL-1 (r=0.9987). Moreover, the proposed immunosensor has a high selectivity to AOZ alone with no significant response to the metabolites of other nitrofuran antibiotics, such as 3-amino-5-morpholinomethyl-2-oxazolidinone (AMOZ), semicarbazide (SEM), and 1-aminohydantoin hydrochloride (AHD). This protocol has been applied to detect AOZ in food samples with satisfactory results. © 2011.

Abstract:A streptavidin functionalized capillary immune microreactor was designed for highly efficient flow-through chemiluminescent (CL) immunoassay. The functionalized capillary could be used as both a support for highly efficient immobilization of antibody and a flow cell for flow-through immunoassay. The functionalized inner wall and the capture process were characterized using scanning electron microscopy. Compared to conventional packed tube or thin-layer cell immunoreactor, the proposed microreactor showed remarkable properties such as lower cost, simpler fabrication, better practicality and wider dynamic range for fast CL immunoassay with good reproducibility and stability. Using α-fetoprotein as model analyte, the highly efficient CL flow-through immunoassay system showed a linear range of 3 orders of magnitude from 0.5 to 200ngmL-1 and a low detection limit of 0.1ngmL-1. The capillary immune microreactor could make up the shortcoming of conventional CL immunoreactors and provided a promising alternative for highly efficient flow-injection immunoassay. © 2011 Elsevier B.V.

Abstract:A transgenic rice line (TRS) enriched amylose and resistant starch has been developed by antisense RNA inhibition of starch branching enzymes. In this study, gelatinisation and crystalline properties, swelling power, water solubility, morphological and structural changes of starches from TRS and its wild-type Teqing (TQ) were carefully investigated during heating. Compared to TQ, TRS starch showed higher gelatinisation temperatures, lower gelatinisation enthalpy and swelling power. Morphological and structural changes showed that TQ starch drastically swelled after 70 °C, then gradually disrupted with increasing heating temperature. The surrounding band of TRS starch restrained granule swelling, though the subgranules disrupted to form the cavity. The results of spectroscopic analyses indicated that A-type crystalline of TQ changed to amorphous starch after 75 °C, while C-type crystalline of TRS gradually changed to B-type crystalline after 75 °C, then became amorphous starch at 95 °C. These results add to our understanding of the effect of heating on the high-amylose rice starch. © 2011 Elsevier Ltd. All rights reserved.

Abstract:The crystallization of poly(trimethylene terephthalate) (PTT) composites containing carbon nanotubes (CNTs) were studied in this work. The electrospinning technology was employed successfully to fabricate thin film samples with well-embedded CNTs for spherulite observations using atom force microscopy. The results show that the composites present a higher overall crystallization rate than that of the neat PTT due to the nucleation effect of the CNTs. Banded spherulites can be observed on both the neat PTT and the composites. The presence of CNTs does not change the twisting mode of PTT crystal, but reduces band spacing and twist period. This is attributed to the enhanced fold staggering level of lamellae caused by the narrowed lamellae size and accelerated spherulite growth, which is further confirmed by analysis through secondary nucleation theory. © 2011 Society of Chemical Industry.

Abstract:The evaluation of the field water cycle under deficit irrigation plays an important role in studying mechanism of field water dynamics, optimization of agricultural water management strategies, and assessment of regional water resources. In this study, the agro-hydrological Soil-Water-Atmosphere-Plant (SWAP) model was used to evaluate the field water cycle for a winter wheat-summer corn double cropping system in Beijing, China under deficit irrigation. A carefully designed field experiment was carried out from 2007 to 2009 with six irrigation treatments. The SWAP model was calibrated with soil water contents of two treatments. The dataset of the main field water balance components including soil water content, profile water storage and water flux through the bottom of the root zone were used to validate the SWAP model. The average root mean square error (RMSE) and the mean relative error (MRE) values of predicted soil water contents were 2.4% and 8.0%, respectively. The dataset of predicted and measured values were close to the 1:1 scale line for both the profile water storage and soil water flux. As an application of the SWAP model, the optimal irrigation management practices for the hydrologic years of 75%, 50% and 25%, respectively, in the Beijing area were obtained. The simulated average amount of water saving and groundwater recharge under the optimal irrigation schedules were about 190 mm and 16.1 mm, respectively. This study indicates that the SWAP model can be used as a powerful tool to simulate the field water cycle and evaluate irrigation practices. © 2010 Elsevier Ltd.

Abstract:The agro-hydrological Soil-Water-Atmosphere-Plant (SWAP) model was calibrated and validated to simulate water-salt transport based on field experiments in an arid region of China. The simulation results show lower soil water content but higher salt concentration under deficit irrigation. Soil water and salinity below 95 cm at 80% evapotranspiration (ETc) treatments and 65 cm at 60% ETc treatments were hardly affected by irrigation. With deficit irrigation, the maximum water uptake and salt accumulated layer moved upward. The SWAP model was also used to predict long-term deficit irrigation with saline water. The salinization process reached equilibrium after utilization of saline water for a few years. In summary, the numerical model proves to be a useful tool for studying water-salt transport under different scenarios and for evaluating irrigation practices for a long period. © 2010.

Abstract:This review summarizes results of the recent research on chemical modifications of alginate that are as yet relatively unexploited commercially. Alginate is a linear, anionic polysaccharide consisting of two kinds of 1,4-linked hexuronic acid residues, namely β-d-mannuronopyranosyl (M) and α-l-guluronopyranosyl (G) residues, arranged in blocks of repeating M residues (MM blocks), blocks of repeating G residues (GG blocks), and blocks of mixed M and G residues (MG blocks). Alginate has an abundance of free hydroxyl and carboxyl groups distributed along the polymer chain backbone, and it, therefore, unlike neutral polysaccharides has two types of functional groups that can be modified to alter the characteristics in comparison to the parent compounds. Methods used for modification of hydroxyl groups of alginate include oxidation, reductive-amination, sulfation, copolymerization and coupling of cyclodextrin units. Methods used for modification of carboxyl groups include esterification, use of the Ugi reaction, and amidation. Furthermore, the characteristics and applications of some alginate derivatives are also summarized. © 2010 Elsevier Ltd. All rights reserved.

Abstract:Digital libraries have been built all over the world. One of the main challenges in maintaining digital libraries is the digital preservation. The aim of digital preservation is to ensure that digital records are filed and are made available throughout time. Each digital library consists of different documents with different file formats. Due to rapid obsolescence in hardware and software technology it is necessary for the libraries to look into the details of the file formats. Thus the file format for long-term preservation plays a very important role during the practices of digital preservation. The article tries to analyzing the current situation of the file formats, then points out the standards in choosing the file format for long-term preservation based on generalizing the researches by scholars. After comparing the PDF and XML, the author thinks the XML file format is more suitable for long-term preservation. © 2011 IEEE.

Abstract:Negative thermal expansion ZrW2O8 thin films has been grown on quartz substrates by pulsed laser deposition (PLD) method followed by annealing at various temperatures. The influences of annealing temperature on the morphology and phase composition of the ZrW2O8 thin films were investigated. The X-ray diffraction (XRD) and X-ray photoelectron spectroscope (XPS) analyses revealed that the as-deposited ZrW2O8 thin film showed an amorphous phase, the stoichiometry of the as-deposited thin film was close to that of the ZrW2O8 ceramic target, the crystallized cubic ZrW2O8 thin films were prepared after annealing at 1200°C. The scanning electron microscope (SEM) confirmed that the ZrW2O8 thin film deposited on the substrate heated at 650°C was smooth and compact, the crystallized cubic ZrW2O8 thin film was a polycrystalline film and its grain size grew to be larger. The high temperature X-ray diffraction analyses showed that all the peaks ascribe to the ZrW2O8 thin film shifted to higher angle with the increasing temperatures, which demonstrated that the cubic ZrW2O8 thin film exhibited negative thermal expansion and its thermal expansion coefficient was calculated to be -11.378×10-6K-1 from 20°C to 600°C. © 2011 Elsevier B.V.

Abstract:The tracking control problem is studied for a class of uncertain non-affine systems. Based on the principle of sliding mode control (SMC), using the neural networks (NNs) and the property of the basis function, a novel adaptive design scheme is proposed. A novel Lyapunov function, which depends on both system states and control input variable, is used for the development of the control law and the adaptive law. The approach overcomes the drawback in the literature. In addition, the lumped disturbances are taken in account. By theoretical analysis, it is proved that tracking errors asymptotically converge to zero. Finally, simulation results demonstrate the effectiveness of the proposed approach. © 2011 Elsevier B.V.

Abstract:Dodecanol was covalently coupled to sodium alginate (NaAlg) via ester functions using 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC-HCl) as a coupling reagent to provide an amphiphilic dodecanol alginate (DA) for subsequent use in oil-in-water (O/W) emulsion application. The structure of DA was confirmed by FT-IR spectrometry. The stability of the emulsions prepared with different concentrations (0.3-1.2 wt%) of DA or 1.0 wt% NaAlg was evaluated by measuring droplet size, microstructure, viscosity and creaming. The results showed that the emulsions containing 1.0 wt% NaAlg, 0.3 and 0.5 wt% DA were unstable and the emulsions containing 0.8-1.2 wt% DA presented better stability during storage. © 2011 Elsevier Ltd.

Abstract:We propose a new algorithm to cluster multiple and parallel data streams using spectral component similarity analysis, a new similarity metric. This new algorithm can effectively cluster data streams that show similar behaviour to each other but with unknown time delays. The algorithm performs auto-regressive modelling to measure the lag correlation between the data streams and uses it as the distance metric for clustering. The algorithm uses a sliding window model to continuously report the most recent clustering results and to dynamically adjust the number of clusters. Our experimental results on real and synthetic datasets show that our algorithm has better clustering quality, efficiency, and stability than other existing methods. © 2011 Elsevier Inc.

Abstract:The CdS/CNTs nanocomposites were prepared by a simple heating refluxing method, and the scattering of CdS on CNTs surface was controlled by a dropping way. The samples were characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM) and ultraviolet-visible diffuse reflectance spectroscope (UV-Vis).The photocatalytic activity of the samples was tested in the degradation of Methylene blue dye wasterwater under simulated sunlight with 500w short arc xenon lamp. The results showed that the photocatalytic activity of CdS/CNTs composites was enhanced by controlling CdS scatter on CNTs surface, and the forbidden band width was appropriate lowered when CNTs was added, and the scatter of CdS on CNTs surface was uniform and the photocata-lytic activity was the highest when the mass ration of CdS with CNTs was 4:1.The CdS composites have good stability and potential industrial application.

Abstract:AgBr/ZnO nanocomposite was synthesized via chemical precipitation from pure ZnO nanowires, AgNO3, and NaBr. Inductively coupled plasma optical emission spectroscopy, X-ray diffraction, and high resolution transmission electron microscopy results confirmed the forming of AgBr/ZnO nanocomposite. High resolution transmission electron microscopy results of the as-synthesized AgBr/ZnO nanocomposite revealed that AgBr nanoparticles were attached to the surface of ZnO nanowires. UV-vis diffuse reflectance spectra of both pure ZnO and AgBr/ZnO nanocomposite displayed a band gap edge at about 350-380 nm. However, compared with pure ZnO, an additional broad tail from approximately 400 nm to 700 nm appeared in the UV-vis diffuse reflectance spectrum of AgBr/ZnO nanocomposite. The photocatalytic studies indicated that the as-synthesized AgBr/ZnO nanocomposite was a kind of promising photocatalyst in remediation of water polluted by some chemically stable azo dyes under visible light. © 2011 Elsevier B.V.

Abstract:People living in the information age, are more and more attention to their lives. It is also said, social life is more important in present and future. The social life contains three fields. In this paper, we propose a new model for active contours to detect objects in a given medical image, in order to facilitate people to have medical treatment. The proposed method is based on techniques of piecewise constant and piecewise smooths Chan-Vese Model, semi-implicit additive operator splitting (AOS) scheme for image segmentation. Different from traditional models, our model uses the level set which are corresponding to ordinary differential equation (ODE). Our model has more improved characteristics than traditional models, such as: less sensibility of noise; unnecessary of re-initialization and high speed by the simplified ordinary differential function. Finally, we validate the proposed model by numerical synthetic and real images. The experimental results demonstrate that our model is at least two times more efficient than the widely used methods.

Abstract:A new algorithm to mine the frequent items in data stream is presented. The algorithm adopts a time fading factor to emphasize the importance of the relatively newer data, and records the densities of the data items in Hash tables. For a given threshold of density S and an integer k, our algorithm can mine the top k frequent items. Computation time for processing each data item is O(1). Experimental results show that the algorithm outperforms other methods in terms of accuracy, memory requirement, and processing speed. © (2012) Trans Tech Publications, Switzerland.

Abstract:Nowadays, the development of information technology is keeping in a fast speed. Large amount of information are exchanged too active to identify the original owner. A serious problem of digital contents copyright violation is happening today and the most effective manner to avoid it is digital watermark technology. In this work, a new approach for digital watermark embedding is presented. This method is different from the traditional ways which are pixel-exchanging and frequency-domain-based watermarking scheme. It combines the pixel-exchanging scheme and frequency-domain-based scheme by exchanges the lower bit plane and imitates the imaging process of a true-lens-imaging system respectively. On the other hand, This method use the point spread function as secret key that keeps the security and spread the embedded information to all bit plane of the image that keeps the robustness. Numerical simulation examples show the effect.

Abstract:People living in the information age, are more and more attention to their own lives. It is also said, social life is more important in present and future. The social life contains three fields. In this paper, we will propose a new method for adjunctive therapy in social life. Recent years, as the bandelets transform has some benefits, many scholars are interested in this field. They proposed many methods to solve different problems in different fields. In this paper, we propose a new maximum local energy method to calculate the low coefficients of images. And then adopt the sum modified laplacian method to select the high coefficients of images. Later, we compare the results with wedgelets transform. In our experiments, we take wedgelets transform, bandelets transform, and LE-wedgelets transform for comparing the results. Beside the human vision, we also compare the results by quantitative analysis. The numerical experiments state clearly that the maximum local energy is an effect way for image fusion, which can get well performance in visual effect and quantitative analysis. During 100 clinic CT/MR fusion experiments in practice, compare with previous methods, the PSNR of our method is improved respectively 5.836, 5.337, 0.035.

Abstract:Three lactobacilli(L26, L34, L106) isolated from naturally fermented rabbit sausage in a traditional way are identified as lactobacillus plantarum, lactobacillus sake and lactobacillus fructosus. Further study of its fermentation property shows that three lactobacilli are effective in acid production, alkali resistant, nitrite resistant and bacteriostatic, and are antagonisticaction free, which can be used as combined rabbit meat starter. In China, rabbit meat is very popular and enjoys the ancient saying that "nothing compares with the pigeon in birds, or the rabbit in beasts". Currently, the futher processing technology research and product development of rabbit meat are at the very outset, and fermented rabbit meat products, mainly treated by natural fermentation, fail to reach a high level of security, resulting in a few reports focusing on inoculated fermented rabbit meat production[1, 2]. Although commercial microbial fermentation agents are available at the market place presently, but the majority are imported products. Direct usage of these strains usually leads to adverse effects upon competition with the dominant colony and incapability to exist among the predominant bacterium crowd, causing a severe loss of characteristic flavor material [3]. However, data indicate that local strains, obtained by screening the natural medium, once meet the related food safety standards, are more competitive to coexist with the local colonies owing to high adaptability to the characteristics of raw meat as well as to the process condition [4, 5]. This article makes an attempt to trial-produce natural fermented rabbit sausage, from which lactic acid bacteria are obtained and purified. And on the basis of systematic identification of the strains' safety and security, we study their fermentation characteristics. Aiming at filtering refined microbial fermentation agent for rabbit meat, the reports are present as follows.

Abstract:Hysteresis current controllers are widely used in PV inverters. The main drawback of conventional hysteresis current control is that the switching frequency is variable, as the hysteresis band is fixed. In this paper an adaptive band hysteresis control algorithm with no derivative calculation is presented. As it will be shown, this algorithm can limit the switching frequency variation within a small range and the algorithm itself is simple and easy to be implemented. The performance of this algorithm, together with the one [10] and conventional hysteresis control has been evaluated by means of simulations performed with PSIM and SIMULINK. Simulation results show the effectiveness of the suggested hysteresis current controller. © (2012) Trans Tech Publications.

Abstract:Digital X/γ-ray imaging technology has been widely used to help people deliver effective and reliable security in airports, train stations, and public buildings. Nowadays, luggage inspection system with digital radiographic/computed tomography (DR/CT) represents a most advanced nondestructive inspection technology in aviation system, which is capable of automatically discerning interesting regions in the luggage objects with CT subsystem. In this paper, we propose a new model for active contours to detect luggage objects in the system, in order to facilitate people to identify the things in luggage. The proposed method is based on techniques of piecewise constant and piecewise smooths Chan-Vese Model, semi-implicit additive operator splitting (AOS) scheme for image segmentation. Different from traditional models, the fast implicit level set scheme (FILS) is ordinary differential equation (ODE). Characterized by no need of any pre-information of topology of images and efficient segmentation of images with complex topology, the FILS scheme is fast more than traditional level set scheme 30 times. At the same time, it performs well in image segmentation of DR images in our experiments.

Abstract:North Pacific Oscillation (NPO) is a concept of climate science. It refers to the zonal wind perturbations through the North Pacific Ocean which caused by the changing pressure between subtropical zone(near the center of the Hawaiian Islands)and Deputy polar low pressure zone(center in the vicinity of the Aleutian Islands). So far, studies have been focused on the abnormal of winter (Dec-Feb) NPO and the corresponding climate affects. Domestic results have shown that NPO has significant impact on our temperature, precipitation and ryphoons. However, very few researches have been done on other seasons and months. © 2012 Springer-Verlag London Limited.

Abstract:The working principle and driven approach of a piezoelectric linear motor which uses axial stretching vibration of cascading piezoelectric elements is introduced. The prototype of that motor is designed and fabricated. It's performance is also tested. The motor's vibrator is a stick and moving object is a cylindrical ring which contacts with vibrating stick in the shape of cylindrical surface. The forward and backward movements of moving object are achieved by utilizing the axial stretching vibration of vibrating stick. The moving direction is altered by changed the frequency of driving signal. The structure of the motor is simple and the power supply is single sine phase. So that it is easy to be smaller. In addition, the thrust force is increased by cylindrical surface contact between moving object and vibrating stick so that it is easy to be practical also. This kind of piezoelectric linear motor is very suitable for precise positioning of objects, fine material handling, and vibration cutting tools. © (2012) Trans Tech Publications, Switzerland.

Abstract:Expanded perlite (EP) modified titanium dioxide (TiO2) with different loading times were prepared by Sol-Gel method. Photocatalytic degradation kinetics of Rhodamine B (RhB) in polluted water by the materials (EP-nanoTiO2), as well as the effects of different loading times and the initial concentration of RhB on photocatalysis rate were examined. The catalytic activity of the regenerated photocatalyst was also tested. The results showed that photocatalyst modified three times with TiO2 had the highest catalytic activity. Degradation ratio of RhB by EP-nanoTiO2 (modified three times) under irradiation for 6 h were 98.0%, 75.6% and 63.2% for 10 mg/L, 20 mg/L and 30 mg/L, respectively.The photocatalyst activity has little change after the five times recycling, and the degradation rate of RhB decreased less than 8%. The reaction of photocatalysis for RhB with irradiation time can be expressed as first-order kinetic mode within the initial concentration range of RhB between 10mg/L and 30 mg/L. EP-nanoTiO2 photocatalyst has a higher activity and stability to degrade RhB in aqueous solution. © (2012) Trans Tech Publications, Switzerland.

Abstract:Different environmental remediation materials were prepared by using Cetyltrimethylammonium Bromide (CTMAB) and/or TiO2 to surface-modify expanded perlite (EP). Photocatalytic degradation of Methyl Orange in polluted water by these materials (CTMAB-EP, TiO2/CTMAB-EP, TiO2-EP and EP), adsorption/ degradation kinetics and relevant factors affecting degradation effects were studied. The results showed that EP had little ability to remove Methyl Orange in water, while EP modified with CTMAB and/or TiO 2 could remove Methyl Orange (MO) significantly, and TiO 2/CTMAB-EP treatment showed the highest removal rate in all treatments. Removal effects of the materials were influenced by dosage of material, shaking time and initial concentration of MO in water. These results indicated that nanoTiO2/CTMAB-Expanded perlite can be used as a new and promising environmental remediation material in efficient removal of organic pollutant from environment. © (2012) Trans Tech Publications, Switzerland.

Abstract:The large number of basic random variables in stochastic process, cause great troubles for calculation and analysis. Based on twice orthogonal expansion in the stochastic process and the expression of uncorrelated random vectors by use of orthogonal functions originate from a single source random variable, a method of triple orthogonal expansion for a stochastic process is put forward ,which can simulate a stochastic process with only one random variable. Example calculation shows the effectiveness of the monophyletic analysis method (MAM).This method can be applied for the other stochastic analysis based on the correlation theory.

Abstract:Fire detection based on sequences of images is more suitable for the need in big room or badly environment. Color and contour are both the important features of a flame image. The method to extract the contour feature of a flame image is developed based on threshold of flame area. The edges of the burning flames jitter continuously, but their contour are similar each other. The method to detect flames in video sequences is proposed here based on flame's dynamic contour. Many experiments show that the system is able to work well and get high detection rate with a low false positive rate.

Abstract:Multi-Relational Sequential mining is one of the areas of data mining that rapidly developed in recent years. However, the performance issues of traditional mining methods are not ideal. To effectively mining the pattern, we proposed an algorithm based on Iceberg concept lattice, adopting optimization methods of partition and merger to just mining the frequent sequences. Experimental results show this algorithm effectively reduced the time complexity of multi-relational sequential pattern mining. © (2012) Trans Tech Publications.

Abstract:In order to probe into orderliness changes of Glutathione S-Transferase (GST) of chloroplast of Puccinellia tenuiflora seedlings under Na 2CO3 stress and its function in resistance to Na 2CO3 stress, relative electric conductance, GST activity and the O2 -.produce rate of the chloroplast, and the osmotic potential of leaves, and the osmotic potential of culture solution of P. tenuiflora seedlings under different Na2CO3 stress were concerned. The result shows that in the Na2CO3 stress range of 0∼0.4%, along with the increase of its intensity under different Na2CO3 stress intensity, GST activity of the chloroplast of seedling leaves of P. tenuiflora is strengthened and GST activity is rapidly weakened with the increase of the intensity of Na2CO3 stress more than 0.4%. The change of GST activity of the chloroplast along with the osmotic potential of culture solution and seedling leaves, relative electric conductance of the seedling leaves as well as the O2 -.produce rate have the similar change tendency. There is significant nonlinear relationship among GST activity of chloroplast, osmotic potential of the seedling leaves and Na2CO3 concentration of culture solution, and among GST activity of chloroplast, O2 -.produce rate and osmotic potential of seedling leaves, and among GST activity of chloroplast, osmotic potential of culture solution and that of seedling leaves, and among GST activity, the O2 -.produce rate of chloroplast and relative electric conductance of the seedling leaves. These indicate that GST of chloroplast plays an important role in the process of seedlings of P. tenuiflora in resistance to the low intensity of Na 2CO3 stress. © (2012) Trans Tech Publications, Switzerland.

Abstract:The electrochemical interaction between bacteria and electrode should be further strengthened at the present stage in order to develop microbial fuel cells (MFCs) to practical power sources. Developing effective anode materials is an alternative to achieving this goal. In this study, the redox activity of polyaniline (PAn) in neutral pH solution was improved by doping ionic liquid (IL) into the synthesized PAn; and the current output of MFC could be enhanced by using IL doped polyaniline (PAnIL) film as anode material. Both cyclic voltermmeter (CV) measurement and MFC operation showed that PAnIL electrochemically synthesized in solution with 30%(v/v) IL addition exhibited the best performance.

Abstract:Carbon nanotube (CNT) filled poly(butylene succinate) composites (PBSCNs) were prepared by melt compounding. The oscillatory rheological properties and crystallization behavior and kinetics were then investigated. The results show that the percolation network of CNTs in the small amplitude oscillatory shear flow is temperature dependent and the values of percolation thresholds reduce gradually with an increase of temperature. Therefore, the principle of time-temperature superposition is invalid on the dynamic rheological responses of those percolated PBSCNs. Besides, the presence of CNTs highly promotes the crystallization of PBS, increasing the overall crystallization rate. But the nucleation mechanism of PBS is not altered with addition of CNTs because the PBS itself is nucleated heterogeneously. © 2011 American Chemical Society.

Abstract:Large-scale AlN nanotip arrays were fabricated via a facile catalysis-free approach using AlCl3 powder and NH3 as starting materials. These nanotips exhibit two intense broad emissions centred at about 375 and 480nm. Both bands do not change significantly or freeze out at a low temperature, showing the features of photoionization of deep donor electrons. Photoluminescence and photoluminescence excitation spectral examination as well as the possible mechanism involved are systematically investigated. It reveals that the two bands are connected with the electronic states determined by the nitrogen vacancy and complex defects. The related energy structures are also provided. This work provides a possible mechanism for defect-related emissions in various AlN nanostructures. © 2011 IOP Publishing Ltd.

Abstract:Data mining provides biological research a useful information analyzing tool. The key factors which influence the performance of biological data mining approaches are the large-scale of biological data and the high similarities among patterns mined. In this paper, we present an efficient algorithm named IRTM for mining frequent subtrees embedded in biological data. We also advance a string encoding method for representing the trees, and a scope-list for extending all substrings for frequency test. The IRTM algorithm adopts vertically mining approach, and uses some pruning techniques to further reduce the computational time and space cost. Experimental results show that IRTM algorithm can achieve significantly performance improvement over previous works. © 2011 ACADEMY PUBLISHER.

Abstract:A dramatic visible light photoelectrochemical sensing platform for the detection of pesticide molecules at zero potential (versus saturated calomel electrode) was first constructed using poly(3-hexylthiophene)-functionalized TiO2 nanoparticles. Poly(3-hexylthiophene) (P3HT) was synthesized via chemical oxidative polymerization with anhydrous FeCl3 as the oxidant, 3-hexylthiophene as the monomer, and chloroform as the solvent, and the functional TiO2 nanoparticles were facilely prepared by blending TiO2 nanoparticles and P3HT in chloroform solution. The resulting photoelectrocatalysts were characterized by scanning electron microscopy, Raman spectroscopy, and X-ray diffractometry. Under visible light irradiation, P3HT generated the transition from the valence band to the conduction band, delivering the excited electrons into the conduction band of TiO2 and then to the glassy carbon electrode. Simultaneously, a positive charged hole (h+) of TiO2 may form and migrate to the valence band of P3HT, which can react with H2O to generate &bullOH, and then it converted chlopyrifos into chlopyrifos&bull that promoted the amplifying photocurrent response. On the basis of the proposed photoelectrochemical mechanism, a methodology for sensitive photoelectrochemical sensing for chlopyrifos at zero potential was thus developed. Under optimal conditions, the proposed photoelectrochemical method could detect chlopyrifos ranging from 0.2 to 16 μmol L-1 with a detection limit of 0.01 μmol L-1 at a signal-to-noise ratio of 3. The photoelectrochemical sensor had an excellent specificity against the other pesticides and could be successfully applied to the detection of reduced chlopyrifos in green vegetables, showing a promising application in photoelectrochemical sensing. © 2011 American Chemical Society.

Abstract:LaNi5-xAlx (x=0, 0.25, 0.75, 1.2) alloys were prepared by vacuum induction melting. The microstructure, mechanical property, cyclic stability of hydrogen absorption/desorption and pulverization resistance of the alloys were investigated. The results demonstrate that the addition of Al element can markedly improve the stability of crystal structure and hydrogen storage capacity of the alloys; with increase of the Al content, the pulverization resistance of the alloys becomes worse at first, and then is improved; mechanical property, which is the main factor, and hydrogen storage capacity jointly influence pulverization resistance property of the alloys; in the atmosphere of ordinary high-purity hydrogen, the main reason for the capacity attenuation of the LaNi5-xAlx (x=0-1.2) alloys should be their intrinsic properties, mostly maybe the disproportionation reaction. © 2011, Northwest Institute for Nonferrous Metal Research.

Abstract:High-amylose cereal starch has a great benefit on human health through its resistant starch (RS) content. Enzyme hydrolysis of native starch is very helpful in understanding the structure of starch granules and utilizing them. In this paper, native starch granules were isolated from a transgenic rice line (TRS) enriched with amylose and RS and hydrolyzed by α-amylase. Structural properties of hydrolyzed TRS starches were studied by X-ray powder diffraction, Fourier transform infrared, and differential scanning calorimetry. The A-type polymorph of TRS C-type starch was hydrolyzed faster than the B-type polymorph, but the crystallinity did not significantly change during enzyme hydrolysis. The degree of order in the external region of starch granule increased with increasing enzyme hydrolysis time. The amylose content decreased at first and then went back up during enzyme hydrolysis. The hydrolyzed starches exhibited increased onset and peak gelatinization temperatures and decreased gelatinization enthalpy on hydrolysis. These results suggested that the B-type polymorph and high amylose that formed the double helices and amylose-lipid complex increased the resistance to BAA hydrolysis. Furthermore, the spectrum results of RS from TRS native starch digested by pancreatic α-amylase and amyloglucosidase also supported the above conclusion. © 2011 American Chemical Society.

Abstract:A rapid synchronous spectrofluorimetric method was first developed for the simultaneous determination of folic acid and riboflavin in nutrimental beverages. Folic acid could be detected by using H2O2 plus Cu(II) as oxidation system to produce pterine-6-carboxylic acid, which had strong fluorescence in aqueous solution, and riboflavin itself was obviously fluorescent. Various operational parameters were thoroughly discussed in terms of their effects on the fluorescence signals, including instrumental parameters, concentration of the oxidation system, and pH. Under optimum conditions, the calibration curves were linear in the ranges of 100-250 μg/L for folic acid and 1-250 μg/L for riboflavin, and the detection limits were 2.0 and 0.014 μg/L, respectively. In addition, this method was applied to the determination of folic acid and riboflavin in nutrimental beverages with satisfactory results. © 2011 American Chemical Society.

Abstract:A thermally responsive polymer, termed as P(IPAAm-AM-BisAM), was prepared by the copolymerization of N-isopropyl acrylamide, acrylamide, and N,N′-methylenebisacrylamide. At room temperature this polymer was dissolved in water to form a low viscous solution so that it could be loaded in a capillary easily. When a high voltage was applied on the capillary, the polymer was stimulated by the Joule heat and transferred from a liquid state into a solid state, acting as a sieving matrix for the separation of proteins according to their molecular weights. The logarithm values of the molecular weights of the proteins correlated linearly with the migration times. This capillary gel electrophoresis of proteins was carried out using a conventional instrument. Using such a copolymer, we can easily realize high-speed, high-efficiency and reproducible capillary gel electrophoresis for proteins without any instrumental rebuilding or investment. © 2011 The Royal Society of Chemistry.

Abstract:Marginal Fisher analysis (MFA) is a representative margin-based learning algorithm for face recognition. A major problem in MFA is how to select appropriate parameters, k1 and k2, to construct the respective intrinsic and penalty graphs. In this paper, we propose a novel method called nearest-neighbor (NN) classifier motivated marginal discriminant projections (NN-MDP). Motivated by the NN classifier, NN-MDP seeks a few projection vectors to prevent data samples from being wrongly categorized. Like MFA, NN-MDP can characterize the compactness and separability of samples simultaneously. Moreover, in contrast to MFA, NN-MDP can actively construct the intrinsic graph and penalty graph without unknown parameters. Experimental results on the ORL, Yale, and FERET face databases show that NN-MDP not only avoids the intractability, and high expense of neighborhood parameter selection, but is also more applicable to face recognition with NN classifier than other methods. © 2011 Higher Education Press and Springer-Verlag Berlin Heidelberg.

Abstract:This paper formulated the spectrum allocation problem as a duopoly market with vertical differentiation in cognitive radio environment. The vertical differentiation showed the not fully substitutability of similar channels. It used static Cournot game model to acquire demand functions. On the basis it presented dynamic Cournot game model to compute the stable region and equilibrium. After determining the convergence condition of stable state, we conducted the simulation. The results show when the speed adjustment parameter is a smaller value and in the stable region, game is smooth and achieves the ultimate Nash equilibrium in a short time. The profit of primary user is more related to channel quality instead of spectrum allocation amount. Because of the not fully substitutability and marginal cost, the primary user who lends too much spectrum could not improve its profit even decrease it sometimes. © 2011 Binary Information Press December, 2011.

Abstract:The model selection for the chamber structure of large-scale navigation lock has a great influence on the quantities of chamber. This paper combines with an actual engineering to analysis the chamber structure of navigation lock with the help of 3D finite element. The analysis result shows that the chamber structure with double-hinges bottom board can reduce the thickness and reinforcement quantity of center inner bottom plating, bending moment of center inner bottom bottom plate is smaller than other times, because the chamber wall can't transfer bending moment to center inner bottom plate with the role of hinges. The chamber structure with monolithic bottom board which is pointed construction joints also can reduce reinforcement quantity and engineering investment by decreasing span moment of center inner bottom plate, considering the weights of chamber wall and back fill has effects on the preloading of foundation in internal force analysis of the chamber structure. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

Abstract:A streptavidin functionalized capillary immune microreactor was designed for highly efficient flow-through chemiluminescent (CL) immunoassay. The functionalized capillary could be used as both a support for highly efficient immobilization of antibody and a flow cell for flow-through immunoassay. The functionalized inner wall and the capture process were characterized using scanning electron microscopy. Compared to conventional packed tube or thin-layer cell immunoreactor, the proposed microreactor showed remarkable properties such as lower cost, simpler fabrication, better practicality and wider dynamic range for fast CL immunoassay with good reproducibility and stability. Using α-fetoprotein as model analyte, the highly efficient CL flow-through immunoassay system showed a linear range of 3 orders of magnitude from 0.5 to 200ngmL-1 and a low detection limit of 0.1ngmL-1. The capillary immune microreactor could make up the shortcoming of conventional CL immunoreactors and provided a promising alternative for highly efficient flow-injection immunoassay. © 2011 Elsevier B.V.

Therefore, there is an urgent need for a simple, reliable, and rapid method for the detection of its marker residue, 3-amino-2-oxazolidinone (AOZ), in food products. In this regard, a sensitive and reliable electrochemical method was presented to detect AOZ based on a novel label-free electrochemical impedimetric immunosensor to address this need. The immobilization of monoclonal antibody against AOZ (denoted as AOZ-McAb) on the gold electrode was carried out through a stable acyl amino ester intermediate generated by 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) and N-hydrosuccinimide (NHS), which could condense antibodies on the self-assembled monolayer (SAM). The detection of AOZ was performed by measuring the relative change in charge transfer resistance before and after AOZ and AOZ-McAb immunoreaction by electrochemical impedance spectroscopy (EIS). Under the optimized conditions, the relative change in charge transfer resistance was proportional to the logarithmic value of AOZ concentrations in the range of 20.0 to 1.0×104ngmL-1 (r=0.9987). Moreover, the proposed immunosensor has a high selectivity to AOZ alone with no significant response to the metabolites of other nitrofuran antibiotics, such as 3-amino-5-morpholinomethyl-2-oxazolidinone (AMOZ), semicarbazide (SEM), and 1-aminohydantoin hydrochloride (AHD). This protocol has been applied to detect AOZ in food samples with satisfactory results. © 2011.

Abstract:The multi-degree-of-freedom spherical driving joint is direct supported and driven by spherical motor owns high mechanical integrity and has advantages on control and trajectory planning. But due to the friction of mechanical bearing which will generate heat, it has bad dynamic characteristics of the driving joint when it works at high speed and even ultra-high-speed. Based on motor technology, magnetic levitation and robotics, a novel multi-degree-of-freedom spherical reluctance driving joint with magnetic levitation is presented, and the coupling model of its electromagnetic suspension force and electromagnetic torque is established. Meanwhile, the joint rotor's non-linear strong coupling three dimensional dynamical model and inverse system model is infered. And the decoupling linearization of state feedback for the joint system is made, which makes the system become linear system with six degrees of freedom. With the control of pseudo-derivative feedback which proportional plus goes first regulator and simulation experiments, it shows that the system of decoupling linearization joint system has the performance of well static, high-speed response, good dynamic characteristics and strong capacity of resisting disturbance. © 2011 Journal of Mechanical Engineering.

Abstract:By accurately considering the axial extension and transverse shear deformation in the sense of theory of Timoshenko beam, geometrically nonlinear governing equations for functionally graded sandwich beams subjected to thermal loads were formulated. By using a shooting method, the obtained boundary value problem of nonlinear differential equations was numerically solved; and thermal buckling and post-buckling responses of transversely non-uniformly heated FGM Timoshenko sandwich beams with fixed-fixed ends were obtained. The effects of material gradient property, surface layer thickness and temperature parameter on the buckling deformation and the tension-bending coupling deformation of the beam were discussed in details, and the temperature distribution in the thickness direction of sandwich beam are plotted.

Abstract:The pump system with bidirectional box-shaped flow passages is of simple structure and good applicability, but its system efficiency is low and vortex often appears in its suction passage causing vibrations harmful to safe operation. To solve these problems, a new curve diversion structure and an inlet pier design were proposed and applied for renovation of a bidirectional flow pumping station. With numerical simulation, the flow fields of the bidirectional system were obtained and the system's hydraulic performances were predicted. Meanwhile, a model was tested on a standard test bench to measure its system performances, and calculations of performance curves were compared with the measurements. Both results for the high efficiency ranges are close to each other, which validates the calculations. It is also shown that the new design, by effectively eliminating the vortex and enhancing system efficiency, ensures safe and economical operation of the pump units. © Copyright.

Abstract:Shaft tubular pump system has a straight and smooth conduit of hydraulic loss less than other types of pump, and it has advantages of lower investment, simpler structure and easier installation and maintenance. To improve its hydraulic performance, its design schemes was compared by 3D numerical simulations under the design requirements of the Pizhou pumping station, a first-stage sub-project of the Eastern Route South-to-North Water Diversion Project. The results were verified by two scale-model tests, flow pattern test and hydraulic performance test. This study reveals that in comparison with the rear-positioned scheme, the flows in the inlet and outlet conduits of the front-positioned shaft tube scheme are more uniform and smooth with less hydraulic losses, and the resulting hydraulic performance of the system is much better. Under low-head conditions excellent performances were obtained with system efficiency greater than 83% at most operation points and NPSHc lower than 5 m. Such a pump system is suitable for Pizhou pumping station, and also suitable for other extra-low-head stations. © Copyright.

Abstract:An adaptive neural network control scheme is proposed for a class of nonlinear switched systems in strict-feedback form. The design is based on the backstepping technique, the Lyapunov function of integral type, the approximation capability of neural networks, and the dwell-time approach. By introducing the adaptive compensation term of the approximation error, and utilizing Young's inequality, the control performance of the closed-loop system is improved. Compared with the existing literature, the proposed approach relaxes the requirements of the system and eliminates the assumption that the amplitude of the state's jump should be related to the tracking error. By theoretical analysis, the closed-loop control system is shown to be semi-globally uniformly ultimately bounded. Finally, simulation results are presented to illustrate the effectiveness of the proposed approach.

Abstract:A kind of negative thermal expansion ZrW2O8 nanorods were synthesized using a hydrothermal method, followed with a post-annealing at 570 °C for 2 h. Effects of HCl concentration on the microstructure, morphology and negative thermal expansion property in resulting ZrW 2O8 powders were investigated by X-ray diffraction (XRD) and transmission electron microscope (TEM). Results indicate that the formation of the precursor ZrW2O7(OH)2(H 2O)2 significantly depends on the HCl concentration, and the precursors ZrW2O7(OH)2(H2O) 2 can form in the 2-8 mol/L HCl solution. With increasing the concentration of the HCl solutions from 2 to 8 mol/L, the rod-like ZrW 2O8 particles become more homogeneous, and the average dimension change from 10 μm × 0.5 μm to 700 nm × 50 nm. All the ZrW2O8 powders obtained in different conditions exhibit negative thermal expansion property, and the average negative thermal expansion coefficients from 15 °C to 600 °C decrease gradually with the increasing HCl concentration. © 2011 Elsevier Ltd and Techna Group S.r.l.
