Trust model is proposed in grid entity transcation because of dynamics and uncertainly of campus grid. In this paper, a trust model in autonomous domain is presented. Researching on trust value calculating and updating in domain discuss the trust value calculating model in campus grid domain, This paper proposes the algorithms about trust value calculating and updating in grid entity.
As an important part of multimedia retrieval, researches on 3D model retrieval concentrate on the shape-based retrieval method. It is a promising way to improve retrieval performance by adopting semantic information. At present, semantics of an object is usually represented by several keywords. However, acquiring each 3D model's semantics is very difficult and expensive. To solve the problem, the...
Diffusive phenomena occurring everywhere in natural and engineering systems. Mathematical modeling and simulation of diffusive phenomena has been an important issue of computational fluid dynamics (CFD) not only in scientific and engineering fields, but also in geoscience and social and medical sciences. How to utilize client-based Web services for interactive computing, especially in P2P systems...
This paper gives a brief overview of version 3.3 of PRISM, a tool for the automatic formal verification of probabilistic systems, and some of the case studies to which it has already been applied to date.
The most important thing of using model checking technology to verify production knowledge base is to build system model from rule set. It is a fundamental but time-consuming job. This paper presents an efficient formal method to verify production knowledge base. Two main contributions of this paper are as follows. Firstly, we propose a dynamic modeling method to build system model of knowledge base,...
Model checking UML statechart can detect various errors and inconsistencies of current system design in the early process of development. However, because of classic statechart lacking of real-time operational semantics, it can not be directly used to verify real-time property of current system. This paper introduces related definition of clock to extend UML statechart to real-time UML statechart,...
