This paper promotes accountability as a central design goal for dependable networked systems. We define three properties for accountable systems that extend beyond the basic secu...
In this paper, we present an automatable decompositional method for the computation of Lyapunov functions for hybrid systems with complex discrete state spaces. We use graph-based ...
: The size and complexity of software systems are continuously increasing, which makes them difficult and labor-intensive to develop, test and evolve. Since concurrent systems are ...
Abstract. This paper is concerned with a method for computing reachable sets of linear continuous systems with uncertain input. Such a method is required for verification of hybrid...
: This paper presents a process for the stepwise refinement of safety code assertions from identified system hazards. The code assertions are intended for use in system safety veri...
