Over the last fifteen years, database management systems (DBMSs) have been enhanced by the addition of rule-based programming to obtain active DBMSs. One of the greatest challeng...
We give a notation and a logical calculus for the description and deductive manipulation of dynamic networks of communicating components. We represent such nets by hierarchical sys...
A smooth orchestrator is a process with several alternative branches, every one defining synchronizations among co-located channels. Smooth orchestrators constitute a basic mechani...
In constraint logic programming, proof procedures for Horn clauses are enhanced with an interface to efficient constraint solvers. In this paper we show how to incorporate constra...
This paper presents a framework to define a semantics for a real-time object-orientation programming language and to verify programs written in the language. The semantics is defi...
