De nos jours, la majorite des objets manufactures sont concus par des logiciels informatiques de CAO. Cependant, lors de la visualisation, d'echange de donnees ou des processus de fabrication, le modele geometrique doit etre discretise en un maillage 3D. Or, dans certaines situations le modele initial peut etre perdu ou indisponible. La representation discrete 3D peut aussi etre modifiee, par exemple apres une simulation numerique, et ne plus correspondre au modele initial. Une methode de retro-ingenierie est alors necessaire afin de reconstruire une representation continue a partir de la...

Atomic transport in solids is a field of growing importance in solid state physics and chemistry, and one which, moreover, has important implications in several areas of materials science. This growth is due first to an increase in the understanding of the fund- amentals of transport processes in solids. Of equal importance, however, have been the improvements in the last decade in the experi- mental techniques available for the investigation of transport phenomena. The advances in technique have stimulated studies of a wider range of materials; and expansion of the field has been strong- ly...
