International audience; We propose and analyze a new formulation of the Linear Sampling Method that uses an exact characterization of the targets shape in terms of the so-called farfield operator (at a fixed frequency). This characterization is based on constructing nea...

This paper investigates moving networks of Unmanned Aerial Vehicles (UAVs), such as drones, as one of the innovative opportunities brought by the 5G. With a main purpose to extend connectivity and guarantee data rates, the drones require hovering locations due to limita...

International audience; SCA (Service Component Architecture) is an OASIS standard for describing service-oriented middleware architectures. In particular, SCA promotes a disciplined way for designing distributed architectures based on a component model and an Architectu...

International audience; Dynamic imaging of the vocal tact is important for modeling speechthrough the acoustic-articulatory relation. The average duration of each sound isabout 80ms. Movements of each articulator, in particular the tongue, should becaptured with suffici...

International audience; This paper presents a novel method to improve the inertial velocity estimation of a mobile body, for indoor navigation, using solely raw data from a triad of inertial sensors (accelerometer and gyroscope), as well as a determined arrangement of m...

International audience; This paper investigates the observability analysis for linear time systems whose outputs are affected by unknown inputs. Three different definitions of observability are proposed. By introducing the Smith form and comparing the invariant factors,...

We define symmetric spaces in arbitrary dimension and over arbitrary non-discrete topological fields K, and we construct manifolds and symmetric spaces associated to topological continuous quasi-inverse Jordan pairs and -triple systems. This class of spaces, called smoo...

National audience; Dans cet article nous nous intéressons au routage en boucle ouverte dans deux files d'attente en parallèle lorsque les services et les inter arrivées avant routage sont exponentielles. Notre but est de trouver la politique de routage optimale au sens ...
