A basal area growth system for single-species, even-aged maritime pine (Pinus pinaster Ait.) stands in Galicia (northwestern Spain) was developed from data of 212 plots measured between one and four times. Six dynamic equations were considered for analysis, and both numerical and graphical methods were used to compare alternative models. The double cross-validation approach was used to assess t...

12-1 This paper describes an environment for the production of computer-based animation. The emphasis in development of this environment has been in the production of a habitable environment for a visually sophisticated but perhaps, computer naive animator. The attempt has been to create for the animator/user an environment which allows for flexible and natural ways for not only interaction wit...

iv Résumé (Solution de guidage navigation pilotage pour véhicules autonomes hétérogènes en vue d'une mission collaborative) L'application classique des techniques d'estimation et de contrôle, ba– sées sur des capteurs de haute performance, à des systèmes utilisant des capteurs de performances médiocres mais adaptés aux besoins nouveaux des troupes légères et à leurs contraintes est un enjeu pou...

In this research report, a new framework based on the notion of capacity sensitivity is introduced to study the capacity of continuous memoryless point-to-point channels. The capacity sensitivity re ects how the capacity changes with small perturbations in any of the parameters describing the channel, even when the capacity is not available in closed-form. This includes perturbations of the cos...

Nous considérons l’anneau des invariants de n points ordonnés sur la droite projective. L’espace (P)//PGL2 est peut-être le premier exemple intéressant d’un quotient GIT. La construction dépend du choix des poids pour les n points. En 1894, Kempe [K] a introduit un ensemble de générateurs (au moins dans le cas où tous les poids sont constants egaux à 1). Ici, nous décrivons les rélations entre ...

New integrals for electric and magnetic potentials of arbitrary time-independent charge distributions moving with constant velocity are derived. In contrast to the familiar retarded potential integrals, the new integrals express the potentials in terms of the position occupied by the charge distribution at the moment t for which the potentials are being determined. Two different methods are use...
