In hierarchical distributed systems, shared data access can be controlled by assigning user groups single cryptographic keys that allow high level users derive low level keys, but...
Abstract. In this paper, reverse partially-marked safe net condition/event systems (RsNCES) are introduced, rules of their functioning are defined and convenient interpretation met...
Abstract. Local confluence is an important property in many rewriting and transformation systems. The notion of critical pairs is central for being able to verify local confluence ...

We formalize paper fold (origami) by graph rewriting. Origami construction is abstractly described by a rewriting sys), where O is the set of abstract origami’s and ary relation...
We examine the approach of encoding planning problems as CSPs more closely. First we present a simple CSP encoding for planning problems and then a set of transformations that can...
