Issue date:August 2011 Publication year:2011 Pages:17-22 Language:Chinese ISSN:16711637 Document type:Journal article (JA) Publisher:Chang'an University, Southen Middle Section of Xi'an City Second Circular Road, Xi'an, 710064, China 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.

Issue date:August 2011 Publication year:2011 Pages:3335-3344 Language:English ISSN:13880764 E-ISSN:1572896X Document type:Journal article (JA) Publisher:Springer Netherlands, Van Godewijckstraat 30, Dordrecht, 3311 GZ, Netherlands 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.

Issue date:August 2011 Publication year:2011 Pages:1280-1288 Language:English ISSN:02728397 E-ISSN:15480569 CODEN:PCOMDI Document type:Journal article (JA) Publisher:John Wiley and Sons Inc., 111 River Street, Hoboken, NJ 07030-5774, United States 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.

Issue date:August 2011 Publication year:2011 Pages:1-12 Language:English ISSN:13704621 E-ISSN:1573773X CODEN:NPLEFG Document type:Journal article (JA) Publisher:Springer Netherlands, Van Godewijckstraat 30, Dordrecht, 3311 GZ, Netherlands 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.

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 Number of references:19 Main heading:Inertial navigation systems Controlled terms:Alignment - Disturbance rejection - Electric attenuators - Navigation - Process control - Reception quality - Sensors - Uncertainty analysis Uncontrolled terms:Attenuation performance - Exosystems - Inertial sensor - Initial alignment - Ins errors - Measurement Noise - Multi objective - Nonlinear modeling - Robust filters - Sensor drift Classification code:922.1 Probability Theory - 801 Chemistry - 731 Automatic Control Principles and Applications - 716.4 Television Systems and Equipment - 704.1 Electric Components - 601.1 Mechanical Devices - 431.5 Air Navigation and Traffic Control Database:Compendex Compilation and indexing terms, Copyright 2011 Elsevier Inc.
