This paper presents a means of structuring specifications in real-time Object-Z: an integration of Object-Z with the timed refinement calculus. Incremental modification of classes ...
This paper introduces a formal model for the description of interactive systems based on the interactor model of [15, 17]. Similarly to that model, it is intended to be used constr...
Fold and unfold are general purpose functionals for processing and constructing lists. By using the categorical approach of modelling recursive datatypes as fixed points of funct...
Abstract. Action refinement in process algebras has been widely studied in the last few years as a means to support top-down design of systems. A specific notion of refinement aris...
Abstract. Web services are increasingly used for building enterprise information systems according to the Service Oriented Architecture (Soa) paradigm. We propose in this paper a t...
