Abstract. Refinement plays a crucial role in "top-down" styles of verification, such as the refinement calculus, but for probabilistic systems proof of refinement is a pa...
Ad hoc networks are a type of computational system whose members may fail to, or choose not to, comply with the laws governing their behaviour. We are investigating to what extent ...
Abstract. We propose an extension of concurrent constraint programming with primitives for process migration within a hierarchical network, and we study its semantics. To this purp...
The high rate of requirement changes make system administration a complex task. This complexity is further influenced by the increasing scale, unpredictable behaviour of software ...
This paper considers distributed systems, defined as a collection of components interacting through interfaces. Components, interfaces and distributed systems are modeled as Petri...
