Health care is one of the most prominent areas for the application of wireless technologies. New services and applications are today under research and development targeting different areas of health care, from high risk and chronic patients' remote monitoring to mobility tools for the medical personnel. In this direction the MobiHealth1 project developed and trailed a system...

Dans le cadre d'une approche pédagogique basée sur l'écriture collaborative d'hyperlivres, nous avons développé et utilisé divers modèles et systèmes d'hyperlivres fondés sur la notion de document virtuel. L'une des composantes de ces hyperlivres est une ontologie de domaine qui sert à la fois à l'organisation de l'hyperlivre et à l'inférence...

A crucial aspect of the Semantic Web is the capacity to add formalized meanings to information to enable non-human actors to process it. This is usually accomplished by linking the information to an ontology that describes the domain's concepts. In the Web's context it does not seem realistic to represent this semantic layer on a central server, as this model would not...

Exception handling continues to be a challenging problem in object oriented system development. One reason for this is that today's software systems are getting increasingly more complex. Moreover, exception handling is needed in a wide range of emerging application areas, sometimes requiring domain-specific models for handling exceptions. Moreover, new programming paradigms...

The forthcoming wide availability of high bandwidth public wireless networks will give rise to new mobile health care services. Towards this direction the MobiHealth 1,2 project has developed and trialed a highly customisable vital signals ' monitoring system based on a Body Area Network (BAN) and an m-health service platform utilizing next generation public wireless networks....

The forthcoming wide availability of high bandwidth public wireless networks combined with the evolution of performant body area networks will give rise to new mobile health care services. The MobiHealth , , project has developed and trialed a customisable vital signals' monitoring system based on a Body Area Network (BAN) and an m-health service platform utilizing UMTS and GPRS...

At a stationary Markov equilibrium of a Markovian economy of overlapping generations, prices at a date-event are determined by the realization of the shock, the distribution of wealth and, with production, the stock of capital. Stationary Markov equilibria may not exist; this is the case with intra-generational heterogeneity and multiple commodities or long life spans. Generalized...

Kreps–Porteus preferences constitute a widely used alternative to time separability. We showin this paper that with these preferences utility maximization does not impose any observable restrictions on a household’s savings decisions or on choices in good markets over time. The additional assumption of a weakly separable aggregator is needed to ensure that the assumption of utility...
