Retrenchment is presented in a simple relational framework as a more flexible development concept than refinement for capturing the early preformal stages of development, and brie...
Abstract. Coalgebras are categorical presentations of state-based systems. In investigating parallel composition of coalgebras (realizing concurrency), we observe that the same alg...
We consider concurrent games played on graphs, in which each player has several qualitative (e.g. reachability or B¨uchi) objectives, and a preorder on these objectives (for insta...

We present an automata theoretic framework for modular schedulability analysis of real time asynchronous objects modeled in the language Creol. In previous work we analyzed the sch...

Safety critical systems, such as aviation systems controlled by software, often have hard real-time requirements. Producing the correct resultat the right time is thefundamental g...
