This paper puts forward to a new speed control method for the rapid development high-speed railway system. It receive information from track circuit, supervision speed curve, transponder and etc,deduce and calculate the speed value of dynamic expected, and calculate the real-time error. Then the closed-loop speed control system is used to realize the real-time control based on a multi-modal intelligent...
Based on elastic theory strain energy densities of grains with various textures have been calculated in diamond-cubic polycrystalline films. The results show that the strain energy density is anisotropic. The (100) grains have the lowest strain energy density, while the (111) texture corresponds to the highest one. It is the reverse for surface energy density. Therefore, strain energy minimization...
