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.

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.

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.

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.

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.
