NCS (Network Coordinate System) provides us an effective way through which we can predict a network node's distance. NCS has been applied to a huge number of Internet applications. In this paper, we build a differential dynamic model to analyze the global dynamical behavior of a famous NCS algorithm Vivaldi and study the convergence problem existing in it. As a result, our model suggest that TIVs...
With regard to the critical problem in the re-initialization process of Level Set interface capture method, a formula of smoothing parameter in Level Set re-initialization equation and an implicit re-initialization method are proposed. The effectiveness is verified by numerical experiments, and the improved method is used in computing the propagation of small curvature bending detonation wave problem...
