Java programs perform many synchronization operations on data structures. Some of these synchronizations are unnecessary; in particular, if an object is reachable only by a single ...
As video data is penetrating many information systems the need for database support for video data evolves. In this paper we present a generic data model that captures the structu...
The product of safe Petri nets is a well known operation : it generalizes to concurrent systems the usual synchronous product of automata. In this paper, we consider a more general...
One of the most important operations in spatial access needed systems are spatial joins. Using for processing such operations R-tree like structures is intensively studies now. Th...
Optimization and design of production and service operations has been a cornerstone of simulation applications for many years. Recently there has been increasing interest in excel...
