We introduce the notion of hierarchical group signatures. This is a proper generalization of group signatures, which allows multiple group managers organized in a tree with the si...
Abstract. A simple nonconstructive argument shows that most 3CNF formulas with cn clauses (where c is a large enough constant) are not satisfiable. It is an open question whether ...
The reconfigurable mesh model for massively parallel computing has recently been rediscovered and proposed as the basis of a practical many-core architecture. With this paper, we...
For the practical development of provably correct software for embedded systems the close integration of CASE tools and verification tools is required. This paper describes the co...
We introduce PLC-Automata as a new class of automata which are tailored to deal with real-time properties of Programmable Logic Controllers (PLCs). These devices are often used in...
