Abstract. Circus is a combination of Z and CSP that supports the development of state-rich reactive systems based on refinement. In this paper we present JCircus, a tool that autom...
Abstract. Continuous-time Markov decision process are an important variant of labelled transition systems having nondeterminism through labels and stochasticity through exponential...
State-based refinement relations have been developed for use on the Object-Z components in an integrated Object-Z / CSP specification. However this refinement methodology does not ...
We describe a construction of the real numbers carried out in the Coq proof assistant. The basis is a set of axioms for the constructive real numbers as used in the FTA (Fundamenta...
Synchronous Data flow (SDF) graphs have a simple and elegant semantics (essentially linear algebra) which makes SDF graphs eminently suitable as a vehicle for studying scheduling o...
