— An important property of embedded systems is dependability. Today this addresses mostly safety and reliability. Guaranteeing these properties is normally done by adding redunda...
Like other software artefacts, metamodels evolve over time. We propose a transformational approach to assist metamodel evolution by stepwise adaptation. In the first part of the p...
We observe that the principal typing property of a type system is the enabling technology for modularity and separate compilation [10]. We use this technology to formulate a modul...
Real-time systems operate in \real," continuous time and state changes may occur at any real-numbered time point. Yet many veri cation methods are based on the assumption that...
Today many formalisms exist for specifying complex Markov chains. In contrast, formalism for specifying the quantitative properties to analyze have remained quite primitive. In th...
