In this paper, we study the maintenance of role-based access control (RBAC) models in database environments using transitive closure relations. In particular, the algorithms that ...
The design of safety-critical systems has typically adopted static techniques to simplify error detection and fault tolerance. However, economic pressure to reduce costs is exposi...
In the b-degree constrained Euclidean minimum spanning tree problem (bMST) we are given n points in [0;1]d and a degree constraint b 2. The aim is to nd a minimum weight spannin...
Most software applications use a relational database for data management and storage. Interaction with such a database is often done by letting the program construct strings with ...
Bounded semantics of LTL with existential interpretation and that of ECTL (the existential fragment of CTL), and the characterization of these existentially interpreted properties ...
