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:The synchronal motor is widely used in electric drag system which needs no timing. Setting out from inherent mechanical character of the synchronal motor, the load's character of water pump's start, and basing on moment balance equation and mechaelectronic inertia time constant expression, this paper based a mathematic model of synchronal motor group's starting dynamics duration. To combined with the locale test of large-scale synchronal motor in BAOYING pump station of the South-North Water Diversion project and through analyzing, the result of calculation accorded with that of locale test. It validated the correctness of the mathematic model of synchronal motor group's starting dynamics duration. Simultaneity the result of locale test indicated starting dynamics duration has relation to the load's magnitude. The bigger the load is, the longer the starting dynamics duration is. The production have supervise significance on pump station design and lectotype of large-scale pump station motor group, ensuring the safety of South-North Water Diversion project's operation.

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.
