This paper presents a system for querying treebanks. The system consists of a powerful query language with natural support for cross-layer queries, a client interface with a graph...
Abstract Queueing Petri nets are a powerful formalism that can be exploited for modeling distributed systems and analyzing their performance and scalability. By combining the model...
Computational grids clusters, provide powerful computing resources for executing applications of large scale. In Grid (clusters) usually several applications run simultaneously.Th...
Animated crowds are effective to increase realism in virtual reality applications. However, rendering crowds require large computational power. In this paper, we present a techniq...
One of the most important issues for ubiquitous computing is the problem of encrypting content in the devices, as the heterogeneity in the devices nature, capabilities, mobility an...
