We examine how computer system problems can be derived from real application problems, with a particular focus on the relevance of some assumptions, especially those related to co...
Focusing on deixis in human computer interaction this paper presents interdisciplinary work on the use of co-verbal gesture . Empirical investigations, theoretical modeling, and co...
We introduce the Symphony framework, a software ion layer that can sit on top of grid systems. Symphony provides a unified API for grid application developers and offers a graphic...
We present a very efficient multi-party computation protocol unconditionally secure against an active adversary. The security is maximal, i.e., active corruption of up to t < n/...
A geometric approach to the computation of precise or well approximated tolerance zones for CAD constructions is given. We continue a previous study of linear constructions and fr...
