Xiaoyan Leitic permeability, and σ is the specific conductivity of the medium. The integral in Eq. 1.1 identifies the flow of energy crossing the boundary surface . reached by the optical wave. Thus, when dealing with a transfer of energy of optical radiation in the absence of moving elements or conductors, th

Model and Algorithm for Track Element and Vehicle Element,e track-subgrade system once. And in the following computation of each time step, it only needs to assemble the stiffness matrix, mass matrix and damp matrix of the vehicle element into the global stiffness, mass and damping matrices of the track-subgrade system. Therefore, computational efficiency
