Abstract—This paper studies a constrained optical signal-tonoise ratio (OSNR) optimization problem in optical networks from the perspective of system performance. A system optimi...
This paper addresses the problem of scheduling jobs in soft real-time systems, where the utility of completing each job decreases over time. We present a utility-based framework fo...
Mediator systems integrate distributed, heterogeneous and autonomous data sources, but their e ective use requires the solution of hard query optimization problems. This is usuall...
Many would argue that future breakthroughs in software productivity will dependon our ability to combine existing pieces of software to produce new applications. An important step...
We here consider transition systems of Elementary Net Systems with Inhibitor Arcs. There are basically two di erent types of non-interleaving semantics of such Petri nets, the a-po...
