In this paper, we study the problem of power efficient tracking interval management for distributed target tracking wireless sensor networks (WSNs). We first analyze the performance of a distributed target tracking network with one moving object, using a quantitative mathematical analysis. We show that previously proposed algorithms are efficient only for constant average velocity objects howev...

Knowledge management is one of the critical issues for the improvement of enterprise performances. Different methods exist for extracting and formalizing knowledge in order to create knowledge-based applications. Most of integrated design and manufacturing technological processes are more or less based on knowledge that has been translated into models and then into Knowledge-Based Computer-Aide...
