We study the specification of access control policy in large-scale distributed systems. Our work on real-world policies has shown that standard policy idioms such as role hierarc...
We propose lightweight middleware solutions that facilitate and simplify the execution of MPI programs across multidomain clusters. The system described in this paper leverages H2O...
This paper develops a model of an electrical power system, with its inherent embedded communication system, for the purpose of studying the characteristics of power system measure...
We present two new hyperbolic source probability models to effectively represent sub-gaussian and super-gaussian families of sources for dynamic and convolutive Blind Source Recov...
We define a Mobile Database Community (MDBC) as a dynamic collection of autonomous mobile databases in which each database user can access databases in the community through a wir...
