A coloring of a graph is convex if it induces a partition of the vertices into connected subgraphs. Besides being an interesting property from a theoretical point of view, tests f...
In the setting of concurrent self composition, a single protocol is executed many times concurrently by a single set of parties. In this paper, we prove lower bounds and impossibi...
In this paper we study the expressive power of query languages for nested bags. We de ne the ambient bag language by generalizing the constructs of the relational language of Brea...
In this paper, we describe our application of SPIN 1 to model an algorithm used to synchronize the clocks of modules that provide periodic real-time communication over a network. W...
Some of the non interference properties studied in [4, 6, 18] for information flow analysis in computer systems, notably Æ , are reformulated here in a realtime setting. This is...
