We establish new measures of linear independence of logarithms on commutative algebraic groups in the so-called \emph{rational case}. More precisely, let k be a number field and v_{0} be an arbitrary place of k. Let G be a commutative algebraic group defined over k and H be a connected algebraic sub...

Visual Exploration of (French) Commuter Networks

Commuters induce a network structure on the territory linking cities. Geographers study commuter data trying to understand the structure of the network, as a contribution towards urban planning. Our approach is more specifically designed to help geographers identify multiscale phenomenon, reflecting...

Optimisation globale polynomiale appliquée à la rectification projective d'images non calibrées

L'article expose l'application d'une méthode d'optimisation globale au problème de la rectification projectives d'images non calibrées. La plupart des méthodes disponibles dans la littérature utilisent une méthode d'optimisation locale lors de l'étape de minimisation des distorsions projectives. L'a...

On representing the relationship between the mathematical and the empirical

We examine, from the partial structures perspective, two forms of applicability of mathematics: at the “bottom” level, the applicability of theoretical structures to the “appearances”, and at the “top” level, the applicability of mathematical to physical theories. We argue that, to accommodate the...

Nuclear Emergency Response Planning Based on Participatory Decision Analytic Approaches

This work was undertaken in order to develop methods and techniques for evaluating systematically and comprehensively protective action strategies in the case of a nuclear or radiation emergency. This was done in a way that the concerns and issues of all key players related to decisions on protectiv...

Motion Control of a Three-Dimensional Eel-like Robot Without Pectoral Fins

In this paper, recent advances in the design of feedback laws for the 3D movement of an Eel-like robot are presented. Such a robot is under construction in the context of a national French robotic project. The proposed feedback enables the tracking of a desired 3D position of the Eel head as well as...

Les adverbes "zài" du chinois mandarin et "encore" et le système des temps verbaux

The aim of this talk is to compare the semantics and distribution of the Mandarin adverb "zài" and the French adverb "encore". • We will characterize "encore" and "zài" as two repetitive adverbs, sharing the same presuppositional semantics ; • We will show that the interpretive and distributional di...

Least-Squares Joint Diagonalization of a matrix set by a congruence transformation

The approximate joint diagonalization (AJD) is an important analytic tool at the base of numerous independent component analysis (ICA) and other blind source separation (BSS) methods, thus finding more and more applications in medical imaging analysis. In this work we present a new AJD algorithm nam...

Hunting French Ducks in a Noisy Environment

We consider the effect of Gaussian white noise on fast-slow dynamical systems with one fast and two slow variables, containing a folded-node singularity. In the absence of noise, these systems are known to display mixed-mode oscillations, consisting of alternating large- and small-amplitude oscillat...

Guilbaud's Theorem : An early contribution to judgment aggregation

In a paper published in 1952, the French mathematician Georges-Théodule Guilbaud has generalized Arrow's impossibility result to the "logical problem of aggregation", thus anticipating the literature on abstract aggregation theory and judgment aggregation. We reconstruct the proof of Guilbaud's theo...

French Roadmap for complex Systems 2008-2009

A “complex system” is in general any system comprised of a great number of heterogeneous entities, among which local interactions create multiple levels of collective structure and organization. Examples include natural systems ranging from bio-molecules and living cells to human social systems and ...

Cop and robber games when the robber can hide and ride

In the classical cop and robber game, two players, the cop C and the robber R, move alternatively along edges of a ﬁnite graph G = (V , E). The cop captures the robber if both players are on the same vertex at the same moment of time. A graph G is called cop win if the cop always captures the robber...

Analytic Continuation of some zeta functions

This is an expository paper on the meromorphic continuation of zeta functions with Euler products (for example zeta functions of groups and height zeta functions) or without (for example the Goldbach zeta function). As an application we show how a natural boundary of analytic continuation can give a...

An analogue of Serre fibrations for C*-algebra bundles

We study an analogue of Serre fibrations in the setting of C-algebra bundles. We derive in this framework a Leray-Serre type spectral sequence. We investigate a class of examples which generalise on one hand principal bundles with a n-torus as structural group and on the other hand non-commutative t...
