Sensing of urban bus travelling data based on data collection from the Internet enables researchers from different regions to focus on the same study objects and promote the development of corresponding theories and technology. In this study, seven processes running on two servers were employed to retrieve real-time bus travelling data from the official bus information inquiry website of Suzhou, China...
Proper parameter settings of support vector machine (SVM) and feature selection are of great importance to its efficiency and accuracy. In this paper, we propose a parallel time variant particle swarm optimization (TVPSO) algorithm to simultaneously perform the parameter optimization and feature selection for SVM, termed PTVPSO-SVM. It is implemented in a parallel environment using Parallel Virtual...
Vehicle Segmentation algorithm make a effective segmentation as there is a certain contrast between foreground and background, in order to deal with effective segmentation problem,in the case of the low contrast between foreground and background, cased by inappropriate camera parameters set or cloudy day. Then present a method simulating the gray level value in area of interesting changes by using...
A new synchronization control scheme is proposed for Lorenz system. In order to obtain global stability, a state-depended dynamical error equation for the coupled systems is addressed. The control problem is converted into matrix inequalities by choosing proper control parameters. Additional optimization is given to reduce control parameters. Finally, the control problem is numerically solved by BMI...
An attitude regulating control for a class of satellites is proposed. The control scheme is based on the orientation description of Rodrigues or Modified Rodrigues parameters. A method for initial value calculation of the Rodrigues/Modified Rodrigues parameters is given to transmit the stabilizing control into regulation. An attitude control for SAPPHIER satellite is studied. The proposed control...
