Hybrid is a system developed to specify and reason about logics, programming languages, and other formal systems expressed in rder abstract syntax (HOAS). An important goal of Hyb...
In this paper we deal with the problem of modeling railway networks with Petri nets so as to apply the theory of supervisory control for discrete event systems to automatically de...
Abstract. We introduce a visual notation for local specification of concurrent components based on message sequence charts (MSCs). Each component is a finite-state machine whose ...
The field of requirements engineering emerges out of tradition of research and engineering practice that stresses rtance of generalizations and abstractions. abstraction is essent...
The growing complexity of systems and their implementation into silicon encourages designers to look for model designs at higher levels of abstraction and then incrementally build ...
