Abstract. Efficient secure time-stamping schemes employ a 2-level approach in which the time-stamping service operates in rounds. We say that a time-stamping service is accountable...
Abstract: The Duration Calculus is an interval logic introduced for designing realtime systems. This calculus is able to capture important real-time problems like the speci cation ...
Abstract. In spatial reasoning the qualitative description of relations between spatial regions is of practical importance and has been widely studied. Examples of such relations a...
Abstract. We investigate the dynamic variable ordering (DVO) technique commonly used in conjunction with tree-search algorithms for solving constraint satisfaction problems. We fi...
Abstract. This paper presents a framework of specification and verification for distributed real-time object-oriented systems. An earlier paper [17] introduced a process calculus...
