Ontologies are often viewed as the answer to the need for interoperable semantics in modern information systems. The explosion of textual information on the Read/Write Web coupled with the increasing demand for ontologies to power the Semantic Web...
The fundamental goal of virtual worlds is to provide users with the illusion that they are all seeing and interacting with each other in a consistent world. State melding is the core of creating this illusion of a shared reality. It includes two...
A review of error estimation in adaptive quadrature
Article No.: 22
The most critical component of any adaptive numerical quadrature routine is the estimation of the integration error. Since the publication of the first algorithms in the 1960s, many error estimation schemes have been presented, evaluated, and...
A survey of adaptive services to cope with dynamics in wireless self-organizing networks
Cigdem Sengul, Aline Carneiro Viana, Artur Ziviani
Article No.: 23
