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:Based on anti-1ock braking system(ABS) hydraulic test bench, PCMCIA-DAQ1200 acquisition card and LabVIEW software were used, the test program of ABS pressure gradient was written, and the data acquisition was realized automatically. The various experimental tests of ABS pressure gradient were carried out including common braking, long-plus and long-reduction braking and step braking. Test result shows that under common braking, the maximum and minimum decompression gradients are -90.5 and -94.8 MPa·s^-1 respectively, and the maximum and minimum pressurization gradients are 4.1 and 2.7 MPa·s^-1 respectively. Under long-plus and long-reduction braking, the maximum and minimum decompression gradients are -12.1 and -23.0 MPa·s^-1 respectively, and the maximum and minimum pressurization gradients are 21.0 and 4.9 MPa·s^-1 respectively. Under step braking, the maximum and minimum decompression gradients are -1.2 and -3.2 MPa·s^-1 respectively, and the maximum and minimum pressurization gradients are 3.2 and 1.2 MPa·s^-1. The main cylinder pressures of common braking, long-plus and long-reduction braking and step braking are 8, 12, 15 MPa respectively.

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.
