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 ...
—Routing algorithms such as Distance Vector and Link States have the routing table size as ΩΩΩΩ (n), where n is the number of destination identifiers, thus providing only...
Dynamic real-time systems require adaptive resource management to accommodate varying processing needs. We address the problem of resource management with multiple shared resource...
