We explore join optimizations in the presence of both timebased constraints (sliding windows) and value-based constraints (punctuations). We present the first join solution named...
Abstract. Discretionary Access Control (DAC) systems provide powerful mechanisms for resource management based on the selective distribution of capabilities to selected classes of ...
Abstract We propose an alternative notion of asymptotic behaviors for the study of type2 computational complexity. Since the classical asymptotic notion (for all but finitely many...
Grid is an emerging infrastructure used to share resources among virtual organizations in a seamless manner and to provide breakthrough computing power at low cost. Nowadays there...
In this paper we introduce a novel scheme for portable CPU accounting and control in Java, which is based on program transformation techniques at the bytecode level and can be use...
