Modélisation et Animation de Matériaux Hautement Déformables en Synthèse d'Images

In this thesis, we are dealing with computer graphics modeling and animation of highlydeformable materials. Our work is aimed at creating virtual physically-based models of mat-ter, able to automatically deform due to interactions with the environment. Coping withlarge deformation is known to be time consuming, so efficiency and visual quality are thekey issues as they can o...

Synthèse et étude structurale de Na9Cr(MoO4)6

The title compound, nona-sodium chromium(III) hexa-kis[molybdate(VI)], Na9Cr(MoO4)6 was prepared by solid-state reactions. The basic structure units are isolated polyhedral clusters composed of a central CrO6 octa-hedron sharing vertices with six MoO4 tetrahedra to form an open framework in which the Na(+) cations are bound to the free vertices of the MoO4 tetra-hedra. The Cr(3+) cation has sit...

Conception, modélisation géométrique et contraintes en CAO : une synthèse

RÉSUMÉ. Les logiciels de CAO ont pour perspective de devenir de véritables outils d’aide à la conception d’objets physiques. Mais la conception préliminaire reste un domaine de recherche largement ouvert. Cet article de synthèse s’efforce de montrer qu’une approche par contraintes du processus de conception est incontournable pour atteindre ce but. La conception est vue ici comme un processus c...

Biodiversity and landscape—summary, conclusions and perspectives

Based on the contributions in this special issue and further references approaches to indicate biodiversity at the landscape scale are summarized and discussed. The complexity of biodiversity, its levels of aggregation and its specific relations to “natural” and “anthropogenic” environmental conditions depending on spatio-temporal scales are emphasized. The necessity of further research is stre...
