This paper gives a semantics for discrete-event (DE) models that generalizes that of synchronous/reactive (SR) languages, and a continuous-time (CT) semantics that generalizes the...
This paper presents an approach to the design of a learning environment in a mathematical domain (elementary combinatorics) where problem solving is based more on modelling than o...
Application integration is a major trend in information technology today. In this paper we present a number of principles for the design, validation and presentation of process mod...
Safety of interoperation of program fragments written in different safe languages may fail when the languages have different systems of computational effects: an exception raised b...
