The GCommS (Group Communication Support for Distributed Communication Systems) project at Lancaster University is concerned with the support of group communication, especially for applications employing multimedia information. In this paper we introduce a study on requirements of multimedia group applications. Group support in existing systems is discussed. Examples to illustrate group applicat...

This paper describes the design and development of a mobile language lab system called MLab. The MLab system aims to replace the traditional language lab—which typically has a restrictive layout and lacks interaction—with a more user-friendly, low-cost mobile language lab. The target users of MLab are language teachers and students, and the system offers them the freedom to move around and use ...

Modeling and Simulation (M&S) is becoming the core of scientific activities addressing nature complexity. To tackle complexity, we need to integrate heterogeneous formalisms in the same model. Models then become multimodels. Furthermore, M&S softwares have to assist take into account the M&S activity cycle, i.e. modellers to design and to implement models, to define experimental frames and to a...

The paper reports on an experience of designing and implementing an enterprise search application. One of the motivations for the work is the lack of previous studies that deal with the problem of evaluating an enterprise search application. The reason for this lack depends on the building a significant test collection, because each company may be interested in dealing with different types of t...

The article describes the ideas and the results of a example implementation, mediapark. Mediapark is a presentation done for demonstration purposes. It shows the functio...

This paper presents possibility to use Telco 2.0 architecture interfaces to realize a service supporting public transport in agglomerations. Such systems are expected to be easily accessible for everyone and to be available in any location. Such expectations may only be met by a system using the latest achievements in the scope of telecommunication, which are API based on telecommunication oper...
