Remarques sur la frontière de martin biharmonique et la représentation intégrale des fonctions biharmoniques
Soit (Ω, ) un espace biharmonique fort au sens de Smyrnelis dont les espaces harmoniques associés sont des espaces de Brelot qui vérifient l’axiome de proportionnalité. On montre que s’il existe un couple -harmonique > 0 surΩ, alors l’ensemble des points minimaux de la frontière de Martin biharmonique deΩ qui ne sont pas les pôles de couples biharmoniques minimaux est négiligeable dans un sens ...
متن کاملApprendre à ordonner la frontière de crawl pour le crawling orienté
Focused crawling consists in searching and retrieving a set of documents relevant to a specific domain of interest from the Web. Such crawlers prioritize their fetches by relying on a crawl frontier ordering strategy. In this article, we propose to learn this ordering strategy from annotated data using learning-to-rank algorithms. Such approach allows us to cope with tunneling and to integrate ...

متن کاملModélisation par la méthode des équations intégrales de frontière de phénomènes de conduction surfacique sur les isolateurs pollués
The dielectric withstand capabilities of insulating materials is related to their surface electric field and potential distributions. These distributions, in the presence of polluting layers, are quite different from these encountered in classical electrostatics. This work is concerned with the application of boundary integral equations method to the calculation of electric fields and potential...
متن کاملImpossible Frontiers
A key result of the Capital Asset Pricing Model (CAPM) is that the market portfolio— the portfolio of all assets in which each asset’s weight is proportional to its total market capitalization—lies on the mean-variance-efficient frontier, the set of portfolios having mean-variance characteristics that cannot be improved upon. Therefore, the CAPM cannot be consistent with efficient frontiers for...
