We discuss four issues concerning the semantics of Message Flow Graphs (MFGs). MFGs are extensively used as pictures of message-passing behavior. One type of MFG, Message Sequence...
We define a logic EpCTL for reasoning about the evolution of probabilistic systems. System states correspond to probability distributions over classical states and the system evo...

An important step in the development of dependable systems is the validation of their fault tolerance properties. Fault injection has been widely used for this purpose, however wi...
Traditional planning assumes reachability goals and/or full observability. In this paper, we propose a novel solution for safety and reachability planning with partial observabilit...
The testing of the performance of opportunistic communication protocols and applications is usually done through simulation as i) deployments are expensive and should be left to t...
