Modelling Dynamic Access Control Policies for Web-Based Collaborative Systems
Abstract. We present a modelling language, called X-Policy, for webbased collaborative systems with dynamic access control policies. The access to resources in these systems depend...

Typing communicating component assemblages
Building complex component-based software architectures can lead to subtle assemblage errors. In this paper, we introduce a typesystem-based approach to avoid message handling err...

Compositional modeling and refinement for hierarchical hybrid systems
In this paper, we develop a theory of modular design and refinement of hierarchical hybrid systems. In particular, we present compositional trace-based semantics for the language ...

Type-Theoretic Functional Semantics
We describe the operational and denotational semantics of a small imperative language in type theory with inductive and recursive definitions. The operational semantics is given b...
