Cette étude s'inscrit dans le cadre de l'asservissement visuel. La technique d'asservissement visuel consiste à utiliser les informations visuelles fournies par un capteur de vision pour commander les mouvements d'un système dynamique. Un des défis de cette technique est de s'approcher d'un comportement idéal du robot commandé, par exemple une trajectoire satisfaisante. Aujourd'hui, il est bien établi que l'élargissement du champ de vision et surtout le choix d'informations visuelles adéquates ont une incidence positive sur le comportement du robot. Si l'élargissement du champ de vision d'un robot est possible aujourd'hui par l'utilisation des systèmes de vision catadioptrique (couplage caméra et miroir), la sélection d'informations visuelles adéquates reste encore un problème ouvert puisque peu de travaux de modélisation ont été menés sur des systèmes à large champ de vision. Cette étude vise à modéliser des informations visuelles idéales. L'approche proposée est la modélisation par projection sphérique puisque ce modèle de projection est au centre des modèles de projection perspective et catadioptrique. Des résultats significatifs sont présentés pour un objet plan ou volumétrique défini par un ensemble de points et pour des objets volumétriques sphériques tels qu'une sphère et une sphère marquée. Pour chaque objet, un nouveau vecteur minimal d'informations visuelles idéales est proposé. La validation expérimentale de chaque nouveau vecteur montre un comportement adéquat du robot.

Myths have intrigued scholars throughout history. 'Twentieth Century Mythologies' traces the study of myth over the last century, presenting the key theories of mythology and critiquing traditional definitions of myth. The volume presents the work of influential scholars in mythology: the noted Indo-Europeanist Georges Dumezil, the structuralist anthropologist Claude Levi-Strauss, and the historian of religions Mircea Eliade. 'Twentieth Century Mythologies' is an indispensable resource for scholars of religion and myth and for all those interested in the history of ideas.

The Cambridge Yearbook of European Legal Studies provides a forum for the scrutiny of significant issues in EU Law, the law of the European Convention on Human Rights, and Comparative Law with a 'European' dimension, and particularly those issues which have come to the fore during the year preceding publication. The contributions appearing in the collection are commissioned by the Centre for European Legal Studies (CELS) Cambridge, a research centre in the Law Faculty of the University of Cambridge specialising in European legal issues. The papers presented are at the cutting edge of the fields which they address, and reflect the views of recognised experts drawn from the University world, legal practice, and the institutions of both the EU and its Member States. Inclusion of the comparative dimension brings a fresh perspective to the study of European law, and highlights the effects of globalisation of the law more generally, and the resulting cross fertilisation of norms and ideas that has occurred among previously sovereign and separate legal orders. The Cambridge Yearbook of European Legal Studies is an invaluable resource for those wishing to keep pace with legal developments in the fast moving world of European integration.
