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...

This paper establishes stylized facts about business cycles in the late 19th century, using spectral analysis techniques which allow an intuitive description and analysis of cyclical structure in economic fluctuations. Analysis of industrial production data for 13 countries permits the following generalizations. In the advanced North Atlantic economies, a fairly regular long cycle...

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...

Let Ω be a bounded domain with fractal boundary, for instance von Koch's snowflake domain. First we determine the range and the kernel of the trace on ∂Ω of Sobolev spaces of fractional order defined on Ω. This extends some earlier results of H. Wallin and J. Marschall Secondly we apply these results in studying Dirichlet forms related to subordinate reflecting diffusions in non...
