Requirements models for large systems typically cannot be developed in a single step, but evolve in a sequence of iterations. We have developed such an iterative modeling process ...
The aggressive evolution of the semiconductor industry — smaller process geometries, higher densities, and greater chip complexity — has provided design engineers the means to...
We are developing tools to support a conversational metaphor for requirements definition and analysis. Our conversational model consists of three components: (1) a hypertextual re...
In this paper we present a semantic theory for Concurrent ML. It consists of a new effect-based type system and a denotational model. The new type system is based on an extension o...
This paper describes the certification of smart-card applications in the framework of Common Criteria. In this framework, a smart-card application is represented by a model of its...
