We present a Petri net interpretation of the pi-graphs - a graphical variant of the picalculus where recursion and replication are replaced by iteration. The concise and syntax-driven translation can be used to reason in Petri net terms about open reconfigurable systems. We demonstrate that the pi-graphs and their translated high-level Petri nets agree at the semantic level. In consequence, existing...
In this paper, we discuss the automated generation of test cases from contract-oriented specifications. The static analysis we develop rely on original constraint minimization and satisfaction techniques (CSP). We propose a flexible CSP architecture that can apply not only on integer or bounded domains but also on arbitrary types. The original notion of type builders is used to establish the connection...
Like most telecommunication companies and service providers, France Telecom deals with highly heterogeneous applications, ranging from batch oriented to rich interactive multimedia services. Deploying those applications on an utility/grid infrastructure is a promising way to cut operational costs while improving performance (load limitations, QoS, etc.). However, most grid middleware technologies...
