We develop a fast alternative to a complex finite element analysis (FEA) model of cylinder valve in hydrogen fuel cell car based on support vector machine (SVM). The inputs of model are shape parameters of core and plunger of the valve, and the output is the electromagnetic force on the plunger. Uniform Design method is used in the selection of modeling samples. Theoretical and simulation analysis...
A new polarimetric synthetic aperture radar (PolSAR) image CFAR target detector is proposed in this paper. By introducing the inverse Gamma distribution which is extensively used in modeling, the distribution of polarimetric matched filter (PMF) metric, denoted as P_G0, is derived on the product model; Furthermore, a fast and exact parameter estimation method of P_G0 distribution is presented using...
