Recent advances in non-monotonic semantics of deductive databases provide a simple framework for modeling the even-condition-action rules of active databases. This approach unifie...
In this paper, we model the hierarchical structures inherent in cognitive radio networks as the priority queueing system in which primary users interact with the highest priority a...
Model Transformation has become central to most software engineering activities. It refers to the process of modifying a (usually graphical) model for the purpose of analysis (by i...

Semantics represents a major problem area for active databases inasmuch as (i) there is l framework for defining the abstract semantics of active rules, and (ii) the various syst...
—As multiprocessor systems are increasingly used in real-time environments, scheduling and synchronization analysis of these platforms receive growing attention. However, most kn...
