We provide a quantitative description of global minimizers of the Gauss free energy for a liquid droplet bounded in a container in the small volume regime.
Scheduling problems are very important for many (research) fields like management, industrial engineering, operations research and computer science. However many instances of scheduling problems were proven to be NP-hard, therefore the use of heuristics is the de-facto approach in order to cope in practice with its difficulty. In this paper we consider instance problems from the class of uniform parallel...
Topic text segmentation is an important problem in information retrieval and summarization. The segmentation process tries to split a text into thematic clusters (segments) in such a way that every cluster has a high cohesion and the contiguous clusters are connected as little as possible. The originality of this work is twofold. First, we propose new segmentation criteria based on text entailment...
We present a distributed video proxy-cache system that is able to adapt the number of running nodes depending on the client request patterns and available storage and computational resources. Cache related operations are performed with regard to the utility values of the stored objects. We propose the use of a new utility formula which considers a number of object characteristics. This formula is...
The work we are presenting refers to multimedia/video proxy-caching with the aim of designing a dynamic distributed system yielding good performance. For this we introduce a new utility function which is used when performing cache related operations for each stored object. A series of coefficients are used for fine tuning the influence of several object related characteristics inside this utility...
Scheduling problems are very important for many (research) fields. However only for few instances there are polynomial time optimization algorithms, because the vast majority of scheduling problem instances is NP-hard. In such cases heuristic and/or stochastic algorithm are used which tend toward but do not guarantee the finding of optimal solution. The aim of our paper is to investigate the performance...
