In this paper, a network-based algorithm is proposed for group activity recognition with multiple people/objects and crowded scenes. This algorithm models the entire scene as an error-free network. With this network, we model objects in the scene as packages while activities as package transmission in the network. By analyzing these “package transmission” processes, activities can be detected. Based...
Based on analyzing of two basic modeling methods of Extended-Range Electric Bus (E_REB), this paper had established a E_REB's Forward-Simulation model, and described main sub models in detail. Basised to the parameters of a certain E_REB, the Forward model was simulated under UDDS driving cycle, and some significant characteristic curves and dynamics, economics simulation data were obtained. Compared...
The model of road roughness is extremely important to the analysis of vehicle ride comfort and handling stability. In terms of hybrid vehicles, it is fateful in particular. IFFT(Inverse Fast Fourier Transform) theory was described in this paper. Simulation programs were compiled with Matlab software, and the results were compared with the same class of standard power spectral density. The paper had...
With mathematical model of a double track vehicle the mechanism for which suspension bushing stiffness affects on vehicle steady-state yaw response behavior is explained. A vehicle model including front McPherson suspension, rear multilink suspension, power transmission system, steering system, tires and body etc. is built by ADAMS/CAR. With the ADAMS/CAR vehicle model, influence of lateral and longitudinal...
