Surgery simulation system can provide a safe virtual training environment. Cutting of soft tissue plays a very important role in the system. During the operation, the soft tissue exhibits nonlinear property and topology change of the operated tissue usually causes the failure of the pre-computed quantity. The above reasons make the simulation of the real-time cutting a challenging task. This paper...
In order to solve the problems of evaluating system security threat in the complex system, a novel system security threat model based on the attacking-tree graph is proposed in this paper. In this model, an evaluating standard of the feasibility and harmful level of the vulnerability exploitation is given. Then an attacking-tree graph of the target system is constructed based on the relationship among...
