Based on physical properties of peritoneal membrane tissue, Mass Spring Model, which is fit for simulating the deformation of peritoneal membrane tissue in virtual surgery, is built in the paper. Then three numerical solution methods of this model are compared and analyzed to furthur put forward another simulating and modeling method, which is more reasonable and reliable. Also, problems of new model's...
It is a long time since researchers have devoted themselves to trust and reputation rating in E-commerce, and some useful fruits have also been achieved. However in my opinion, there should be a long way to go before human really master the trust mechanism. This paper first investigates swift trust rating indexes, which include interdependence, intensity of focusing role, categorization, environmental...
Building demolition is an important subject for urban construction and development. Blasting simulation is very helpful for safe scientific blasting. It will provide a novel method to decision making for blasting combined with geographic information system (GIS) and virtual reality (VR). Three-dimensional model and scene of the building were constructed based on visualization and modeling function...
In this paper we suppose the formation and evolvement mechanism of city system is the site selection of special entities in the city. We construct model to simulate the mechanism based on multi-agent system, the experiment results show that the distribution of a virtual city system can be generated by the mechanism. Further, we prove that the generated distribution of city system is corresponding...
