Digital Signal Processors are widely used in critical embedded systems to pilot low-level, often critical functionalities. We describe a static analyzer based on abstract interpre...
Abstract. ID-Logic is a knowledge representation language that extends first-order logic with non-monotone inductive definitions. This paper introduces an ID-Logic based framewor...
Multi-valued model-checking is an extension of classical model-checking to reasoning about systems with uncertain information, which are common during early design stages. The addi...
We introduce the concept of a group principal and present a number of different classes of group principals, including threshold-group-principals. These appear to naturally usefu...
We present a theorem-prover based analysis tool for object-oriented database systems with integrity constraints. Object-oriented database specifications are mapped to higher-order...
