Abstract. We present here a formal foundation for an iterative and incremental approach to constructing and evaluating preference queries. Our main focus is on query modification: ...
We aim at a unified and coherent presentation of net models for concurrency like Petri nets and dataflow networks from the perspective of modularity and substitutivity. The major ...
We present a finite representation of all services M where the composition with a given service N is deadlock-free, and a given set of activities of N can be covered (i.e. is not d...
This paper presents new graph-theoretic results appropriate to the analysis of a variety of consensus problems cast in dynamically changing environments. The concepts of rooted, s...
B-series are a fundamental tool in practical and theoretical aspects of numerical integrators for ordinary differential equations. A composition law for B-series permits an elega...
