Let T be a once punctured torus, equipped with a complete hyperbolic metric. Herein, we describe a new approach to the study of the set S of all simple geodesics on T: We introduce a valuation on the homology H 1 (T; ZZ); which associates to each homology class h the length`(h) of the unique simple geodesic homologous to h; and show thatèxtends to a norm on H 1 (T; R): We analyze the boundary o...

We consider a general problem of Structural Design and demonstrate that under mild assumptions it can be posed as a Semidefinite program. The approach in question allows for unified treatment of single-load/multi-load Truss and Shape design with and without obstacles, same as for obstacle-free robust Truss and Shape design. We present three equivalent Semidefinite formulations of the Structural...

Les études sur la Gestion de Performance (GP) publique concernent majoritairement des pays anglo-saxons ou nordiques. Plus précisément, recherche GP dans les collectivités locales s’est concentrée compétences où mesures performance sont plus faciles à élaborer, tandis que peu d’attention a été accordée en matière d&#23...

In clinical trials and life testing problems the responses are time-sequential in nature and a compl~t~ experimentation may involve a prohibitive amount of time and cost •. • Fo't "this reason, progressive· censoring schemes (PCS) are often advocated with a view to terminating the experimentation at the earliest possible stage if the accumulated statistical evidence warrants to do so. In this d...

In this thesis work a complete study of the four quadrants coronagraph is presented This new coronagraph o ers performances of extremely large theorical rejection factor These performances open possibilities of exo planets detection around nearby stars The rst laboratory results gave an attenuation rate higher than on the central peak Thus I naturally studied all the possible uses of this coron...

The IPS system is a large-scale interactive GB-based parsing system (English, French) under development at the University of Geneva. This paper starts with an overview of the system, discussing some of its basic features as well as its general architecture. We then turn to a more detailed discussion of the "right corner" parsing strategy developed for this project. Combining top down and bot to...

A model is presented for a parallel plate electrochemical reactor which has electrodes that are the same size and are close together. That is, the distance between the electrodes (S) is much smaller than the length (L) or width (W) of the electrodes. Consideration of the material balance equations in light of this small aspect ratio (S/L) condit ion leads to predict ions of derived quanti t ies...

Presentation of patients with recurrent stupor associated with apparently elevated levels of an endogenous benzodiazepine-like agent, endozepine-4, has been reported from several centers, and a new syndrome, endozepine stupor has been proposed. We recently reported a case with typical features of this syndrome, which proved to be an example of surreptitious administration of exogenous benzodiaz...
