Sommario/riassunto |
|
In many areas of mathematics, science and engineering, from computer graphics to inverse methods to signal processing, it is necessary to estimate parameters, usually multidimensional, by approximation and interpolation. Radial basis functions are a powerful tool which work well in very general circumstances and so are becoming of widespread use as the limitations of other methods, such as least squares, polynomial interpolation or wavelet-based, become apparent. The author's aim is to give a thorough treatment from both the theoretical and practical implementation viewpoints. For example, he emphasises the many positive features of radial basis functions such as the unique solvability of the interpolation problem, the computation of interpolants, their smoothness and convergence and provides a careful classification of the radial basis functions into types that have different convergence. A comprehensive bibliography rounds off what will prove a very valuable work. |

Sommario/riassunto |
|
Pour le profane, la gouvernance fait d'abord penser au fonctionnement des organisations, ou des institutions, et à la distribution du pouvoir dans ces structures. Le jargon dans ce domaine nous vient des spécialistes de la gestion des organisations, des sciences administratives et de la sociologie urbaine. Toutefois, en devenant de plus en plus un domaine privilégiant tant les analyses du politique que de la société, le thème de la gouvernance se révèle porteur d'une nouvelle ambition : celle de se présenter comme une solution de rechange à l'organisation du pouvoir. Le projet d'une nouve |
