Abstract. There is an increasing need to provide methods for describing information systems which incorporate the integrated use of multiple channels of interaction. To achieve thi...
We build on work in designing modeling languages for hybrid systems in the development of CTA, the Cottbus Timed Automata. Our design features a facility to specify a hybrid system...
Abstract. In many cases, complex system behaviors are naturally modeled as nonlinear differential equations. However, these equations are often hard to analyze because of "sti...
Testing and verification of asynchronously communicating objects in open environments are challenging due to non-determinism. We explore a formal approach for black-box testing by...
: A precise model of the behavioral dynamics is a necessary precondition for the development of collaborative environments. In this paper we present a specification framework for c...
