The packet routing problem, i.e., the problem to send a given set of unit-size packets through a network on time, belongs to one of the most fundamental routing problems with impor...
We present an AC1 (logDCFL) algorithm for checking LTL formulas over finite paths, thus establishing that the problem can be efficiently parallelized. Our construction provides a f...
In this paper, we provide a semantic foundation for role-related concepts in Enterprise Modelling. We use a conceptual modelling framework to provide a wellfounded underpinning fo...
In this position paper we investigate the security of cyberphysical systems. We (1) identify and define the problem of secure control, (2) investigate the defenses that informati...
With Grids, we are able to share computing resources and to provide for scientific communities a global transparent access to local facilities. In such an environment the problems...
