Mobile code has often been mentioned as an attractive technol- ogy for distributing computations inside a Grid consisting of heterogeneous nodes interconnected by a large-scale network. We describe here a Java-based mobile agent model for a Grid infrastructure which addresses issues such as customizable distribution of computation, security, billing and accounting.

MobiHealth aims at introducing new mobile valueadded services in the area of healthcare, based on 2.5 (GPRS) and 3G (UMTS) technologies, thus promoting the use and deployment of GPRS and UMTS. This will be achieved by the integration of sensors and actuators to a Wireless Body Area Network (BAN). These sensors and actuators will continuously measure and transmit vital constants along…

We present a model for creating, managing, and viewing the contents of scientific hyperbooks. The model we propose is based on reusable information fragments and on terminological fragments that contain concept definitions. The definition of concepts, which plays an essential role in scientific writings, are represented in a formal language. These formal definitions can then be…

Using the same data, which could come from local databases or external sources such as the Web, virtual museum designers can build different hyperspaces. It is possible that visitors would find some of them more useful than others. Therefore, virtual museums designers should be equipped with a tool by which various hyperspaces for virtual museums can be easily designed and examined.…

This paper presents first a formal development methodology that enables a specifier to add complexity progressively into the system design, and to formally validate each step wrt client's requirements. Second, the paper describes the application of this methodology to agent-based systems, as well as development guidelines that help the specifier during the development of such…

The first hour following the trauma is of crucial importance in trauma care. The sooner treatment begins, the better the ultimate outcome for the patient. Generally the initial treatment is handled by paramedical personnel arriving at the site of the accident with an ambulance. There is evidence to show that if the expertise of the on-site paramedic team can be supported by immediate…

A hypertext view is a derived hypertext for a given database. We are interested in providing a mechanism of translating hypertext view update operations to appropriate data manipulation operations in database. However, given a hypertext view update operation, we cannot always uniquely determine what needs to be done in terms of database operations to perform the intended hypertext…
