A kind of truss-work used in large-scale tower is introduced in this paper. According to this example, a method of optimization design using the optimum function of ANSYS, which is one of the finite element software, is searched and discussed.
A multi-objective optimized mathematical model of elevator configuration is established based on the analysis of the fact that elevator configuration is a problem of multi-objective optimization, and the weight coefficient of multi-objective function is set according to the characteristics of office building traffic flow. Dynamic Chaos Particle Swarm Optimization (DCPSO) algorithm, which is the improvement of the standard PSO algorithm, is used to optimize the multi-objective optimized mathematical model of elevator configuration. An application case illustrates that the DCPSO algorithm is reasonable and effective in elevator configuration through the application system of elevator configuration which is designed by the hybrid programming technology of VB and MATLAB.
Mathematical model of pipeline pressure is built according to mass conservation. Aiming at solving the poor adaptability of routine PID algorithm and the disturbance of inlet steam, adaptive fuzzy-PID algorithm and Feed-forward controller are proposed in the control system. System simulation is conducted by MATLAB, and parameter self-tuning rules determined by different errors are studied. Simulation results show that the pressure control system has better static and dynamic performance such as quicker response, smaller overshoot and better capacity of resisting disturbance.
Vehicle segmentation is the key of the traffic video image analysis, the movement state of vehicles can be understudied to get traffic flow parameters. Based on the traffic scene characterized by gradual change, the paper present the background model reconstruction with time-space and self-similarity of background. Video frame image is differenced from background, and binary to get the vehicle template. According to the template, movement vehicle will be segmented from it, the results of the experiment confirmed the effectiveness of algorithm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
