We define a mechanism for specifying performance queries which combine instantaneous observations of model states and finite sequences of observations of model activities. We reali...
In the paper we present an ACP-like process algebra which can be used to model both probabilistic and time behaviour of parallel systems. This process algebra is obtained by extens...
For many systems, timing aspects are essential. Therefore, when modelling these systems, time should somehow be represented. In the past, many timed process algebras have been dev...
Abstract. Relational algebra has been a crucial foundation for relational database systems, and has played a large role in enabling their success. A corresponding XML algebra for X...
