In the context of information system engineering, we propose a four-layer metamodeling architecture with a comprehensive set of operations on metamodels. Our architecture enables ...
Parallel programming on distributed memory systems is one of the most challenging research areas in parallel computingtoday. Objectbased parallel programming languages are an impor...
The investigation and the development of self-organizing systems are especially needed for operation and control in massively distributed systems such as Sensor and Actor Networks...
The Conceptual Programming environment, CP, being developed at the Computing Research Laboratory (CRL), is a complete knowledge representation visual programming environment for u...
We introduce the concept, model, and policy-specific algorithms for inferring new access control decisions from previous ones. Our secondary and approximate authorization model (...
