Modelling multi-tasking behaviour is an important phase of real-time system design. It is shown how task scheduling principles can be captured in a CCS-based process algebra via ex...
The soundness of device drivers generally cannot be verified in isolation, but has to take into account the reactions of the hardware devices. In critical embedded systems, interf...
Cellular automata are usually updated synchronously and thus deterministically. The question of stochastic dynamics arises in the development of cellular automata resistant to nois...
Abstract. We consider asynchronous networks of finite-state systems communicating via a combination of reliable and lossy fifo channels. Depending on the topology, the reachability...
In a recent work, we have shown that it is not possible to dependably build any type of distributed f fault or intrusiontolerant system under the asynchronous model. This result f...
