The theory of satellite loss resulting from a giant impact on Uranus (Parisi and Brunini 1997, Planet. Space Sci. 45, 181–187) is revisited, in the light of the discovery of its five outer moons (Gladman et al. 1998, Nature 392,…

In most of the triathlon races, the 10km-run is critical to win and, just a few seconds, may separate the gold and the silver medal. To our best knowledge, no study has analyzed the biomechanical differences among the first qualified…

In the UK, a series of policies and practices since
the 1980s have increasingly involved service users
and carers in the policy and planning of mainstream
services (Department of Health, 2000; 2001; 2004).
The knowledge base on which services are…

We develop a novel autonomous control synthesis strategy called Phase Space Navigator for the automatic synthesis of nonlinear control systems. The Phase Space Navigator generates global control laws by synthesizing flow shapes of dynamical systems and planning and navigating system…

The purpose of the present paper is to review the current knowledge about cholesterol gallstone disease. It is generally accepted that the formation of cholesterol gallstone requires three major pathogenic defects, namely, supersaturation, nucleation and crystal growth as well as…

Knowledge is one of the most precious resources of an organization. Every organization wishes to preserve and fully utilize its knowledge. Within organization knowledge is present in various forms, may be in the minds of workers or in documented form.…

Since huge amounts of spatial data can be easily collected from various applications, ranging from remote sensing technology to geographical information system, the extraction and comprehension of spatial knowledge is a more and more important task. Many excellent studies on…

Farmers from Camaquã, Rio Grande do Sul, Brazil, were shown to have a holistic view of the quality of the soil they are cultivating. Progress towards sustainable land management will come from the synergy of both local and formal scientific…

On étudie l’application des algorithmes de décomposition matricielles tel que la Factorisation Matricielle Non-négative (FMN), aux représentations fréquentielles de signaux audio musicaux. Ces algorithmes, dirigés par une fonction d’erreur de reconstruction, apprennent un ensemble de fonctions de base et un…
