This chapter is dedicated to the de nition of relevant sets of shapes and that of de ning a metric on them. Following a recent research monograph by Delfour and Zolesio [33], we consider the characteristic functions of the subsets of R2 and their distance functions. The L2 norm of the di erence of characteristic functions, the L∞ and the W 1,2 norms of the di erence of distance functions de ne ...

réparation des dommages contractuels selon la convention de la vente internationale de marchandises (1980, vienne) étude de droit comparé

en matière de réparation de dommages contractuels, il n’ y a pas de différence sensible entre la convention de la vente de marchandises de 1980 et le droit des états, - droit iranien, droit français droit égyptien et droit libanais -, ayant fait objet de la présente étude. comparés entre eux, ces divers droits, pourtant faisant partie des systèmes différents, révèlent des ressemblances manifest...

Changement climatique et toponymie. Étude de la répartition ancienne du hêtre à travers ses traces toponymiques

In this paper we evaluate the feasibility of estimating the previous distribution of a tree species, the beech, from the analysis of toponyms presently in use and referring to this species. Specialists from toponymy, agromomy and geometics have been involved. Toponyms are a precious source of information about past distribution: more than 6100 toponyms referring to beech have been detected. MOT...

Etude sur la digestion pancratique de la caseine pour la production de la toxine tetanique

Thèse de doctorat de l ’ École Polytechnique

In this work, three surface functionalization processes have been studied: the spontaneous grafting fromdiazonium salts, the chemically induced grafting from diazonium salts and the chemically induced graftingfrom diazonium salts in presence of vinylic monomers (which is Graftfast). These processes work at roomtemperature, atmospheric pressure, in aqueous medium and without any ext...
