We prove co-N2ExpTime-hardness for conjunctive query entailment in the description logic ALCOIF , thus improving the previously known 2ExpTime lower bound. The result transfers to ...
We present TCTLKD, a logic for knowledge, correctness and real time. TCTLKD is interpreted on real time deontic interpreted systems, and extension to continuous time of deontic int...
We present a system for describing and solving closed queuing network models of the memory access performance of NUMA architectures. The system consists of a model description lan...
In this paper, we compare the underlying models of computation of the system description languages SystemC and Esterel. Although these languages have a rather different origin, we...
When something unexpected happens in a large production system, administrators must first perform a search to isolate which components and component interactions are likely to be...
