In the traditional method, the customer credit evaluation precision is insufficient, which causes the enterprise into a dilemma situation. In view of this problem, this article...
The Cox proportional hazards regression (Cox model) is commonly used to model survival data as a function of covariates. Simulation studies, which use computer intensive procedures to assess the performance of a variety of statistical methods, are increasingly employed in evaluating the properties of the Cox model. The generation of survival data is the most fundamental and important component in...
The traditional network simulator don't have the ability of simulation for the process of large-scale network security incidents outbreak, we designed a grid-based Internet worm behavior simulator which is consisted of foreground applications and background analog subsystems in parallel. It makes the most of the benefit of the grid computing capability, resource and task management. The experimental...
Coordination is a vital aspect of any type of interaction between computer agents in open distributed systems such as the Web. As distributed systems become more ubiquitous, autonomous and complex, the need to ground them on common data model grows stronger. In particular, Semantic Web services are based on synchronous message exchange, thus being incompatible with the REST architectural model of...
