The Co-simulation technology for complex product development, design, innovation, assessment, management provided full support. Based on the analysis of complex products co-simulation features, functions and modeling on the basis of the process, based on the HLA/WE_RTI co-simulation of complex product platform and its architecture, Based on a simulation of product integration modeling, simulation...
Extracting invariable features is one key issue for 3D model searching. A novel invariable feature extraction method, namely geometry projection based histogram model, is proposed for 3D model description. Different from the traditional method, one projection plane (or surface) is created for each 3D model, and the points of 3D models are projected to the projection plane (or surface), and then the...
Particle swarm optimization (PSO) algorithm is an optimization algorithm in the field of evolutionary computation, which has been applied widely in function optimization, artificial neural networkspsila training, pattern recognition, fuzzy control and some other fields. Original PSO algorithm could be trapped in the local optimum easily, so in this paper we improved the original PSO algorithm using...
