The temperature of proton exchange membrane fuel cell stack and the stoichiometric oxygen in cathode have relationship with the performance and life span of fue
An elastic-viscoplastic constitutive model was adopted to analyze asymptotically the tip-field of moving crack in linear-hardening materials under plane strain
Metallic corrosion is a serious problem in the application of a hygroscopic inorganic dust-depressor. The basic characteristics of a hygroscopic inorganic dust-
Dispersion copolymerization of styrene with polyethylene glycol 200-dimethacrylae as the cross-linking agent was completed by using poly(N-vinyl pyrrolidone) an
The large deflection problem of cantilever beams was studied by means of the biparametric perturbation method and the first order derivative substitution from p
Nd8.1Dy0.9Fe76.95Co8.55B5.5 nanocomposite magnets annealed with and without a 10 T magnetic field were investigated in this article. The ribbons with coexisting
声波和地震波是军事车辆类型识别的重要信息源,针对军事车辆运动时产生的声波和地震波,采用短时傅里叶变换提取其波形数据的频谱特征向量,提出基于能量频谱密度进行二次特征选择,构造声波和地震波频谱特征向量子空间,从而降低了特征向量的维数.应用支持向量机(SVM)和最近邻分类法(KNN)分别对声波和地震波数据来进行军事车辆分类,结果表明:基于能量频谱密度的二次特征选择方法能有效地构造出声波和地震波的特征子空
The concept of Fan-Browder mappings was first introduced in topological spaces without any convex structure. Then a new continuous selection theorem was obtaine
In order to find a feasible way to control excavator’s arm and realize autonomous excavation, the dynamic model for the boom of excavator’s arm which was rega
By using the variational method and anneal simulation, we study in this paper the self-trapped magnetic polaron (STMP) in two-dimensional anti-ferromagnetic mat
