Abstract. The unfolding method, initially introduced for systems modelled by Petri nets, is applied to synchronous products of transition systems, a model introduced by Arnold [2]....
We consider point-line geometries having three points on every line, having three lines through every point (bislim geometries), and containing triangles. We classify such geometr...
We consider the minimum equivalent digraph (directed network) problem (also known as the strong transitive reduction) and its maximum objective function variant, with two types of...
Research on cross-language information retrieval (CLIR) has typically been restricted to settings using binary relevance assessments. In this paper, we present evaluation results f...

Hybrid transition systems in their full generality describe continuous behaviour by a set of equations in each mode an algebraic or di erential equation for each state variable in ...
