The constraint paradigm provides powerful concepts to represent and solve different kinds of planning problems, e. g. factory scheduling. Factory scheduling is a demanding optimiz...
We are building an operating system in which an integral run-time code generator constantly strives to improve the quality of already executing code. Our system is based on a plat...
The design of secure buffer managers for database systems supporting real-time applications with firm deadlines is studied here. We first identify the design challenges and then p...
In this paper, we present a new cost model for nearest neighbor search in high-dimensional data space. We first analyze different nearest neighbor algorithms, present a generaliza...
This paper proposes a strategy for parallel composite event detection in Active database systems (DBS). Up to now, the detection is sequential and totally synchronized, and thus p...
