Increasingly, software are required to be ready to adapt itself to the changing environment caused by a wide range of maintenance, evolution and operation problems. Furthermore, in large complex distributed systems and continuous running systems, the traditional approaches to bringing about change require that the system be taken offline temporarily, which(More)
In the operational simulation field, joint operational simulations bring complex dependencies between systems across different services. Different platforms and simulations also need interoperability, which attracts more and more attention of computer scientists. This paper introduces the Intelligent Mobile Agent into operational simulation field, it(More)
Due to the growing complexity of computing systems, and the increasing demand for high availability and reliability of them, adapting software at runtime is becoming more and more important. However, there is not sufficient support for dynamic software adaptation at the level of programming languages. In this paper, we investigate a language feature, namely(More)
This paper proposes a new classification approach; we call the Graph Augmented Bayes classifier (GAB). We show that naive Bayes classifier is a special case of GAB under the conditional independence assumption. GAB relaxes the conditional independence assumptions and takes into account of the influences on an attribute from all other attributes, and extends(More)
