Abstract. Theories defined in a process model are formalized and studied. A theory in a process calculus is a set of perpetually available processes with finite interactability, ea...
Abstract. To support model-based development and analysis of embedded systems, the specification language VDM++ has been extended with asynchronous communication and improved timin...
Abstract. Many long-lived and distributed systems must remain available yet evolve over time, due to, e.g., bugfixes, feature extensions, or changing user requirements. To facilit...
Abstract. This paper shows that asynchronous fault detection is a practical way to reflect partial failure in a network-transparent distributed programming language. In the network...
When a new component is added to an existing, distributed system, it has to co-operate with existing components in a way that doesn’t interfere badly with the original system. A...
