The hierarchy of untimed equivalences is well understood for action-based systems. This is not the case for timed systems, where it is, for example, possible to detect concurrency ...
This paper presents assume-guarantee style substitutivity results for the recently published timed I/O automaton modeling framework. These results are useful for decomposing verifi...
Davies and Wakerly show that Byzantine fault tolerance can be achieved by a cascade of broadcasts and middle value select functions. We present an extension of the Davies and Waker...

Abstract. Circus is a combination of Z and CSP that supports the development of state-rich reactive systems based on refinement. In this paper we present JCircus, a tool that autom...
Testing application behavior in the presence of I/O failures is extremely difficult. The resources used for testing usually work without failure. Failures typically cannot be initi...
