The extraction of reusable software components from existing systems is an attractive idea. The goal of the work in this paper is not to extract a component automatically, but to ...
The Numerical Propulsion System Simulation (NPSS) project has been initiated by NASA to explore the use of computer simulation in the development of new aircraft propulsion techno...
Rewriting is a computational paradigm that specifies the actions, but not the control. We introduce a hierarchical structure repreat a high level of abstraction, a form of control....
The states of a computing system bear information and change time, while its events bear time and change information. We develop a primitive algebraic model of this duality of tim...
We develop the rst steps of a theory of concurrency within the framework of evolving algebras of Gurevich, with the aim of investigating its suitability for the role of a general f...
