Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Magnetic correlations at graphene edges: Basis for novel spintronics devices

Oleg Yazyev

Magnetic zigzag edges of graphene are considered as a basis for novel spintronics devices despite the fact that no true long-range magnetic order is possible in one dimension. We study the transverse and longitudinal fluctuations of magnetic moments at zig ...

Pheromone-based Swarming for Position-less MAVs

Dario Floreano, Jean-Christophe Zufferey, Sabine Hauert, Laurent Winkler

Unlike existing aerial swarm systems, we aim at developing algorithms which do not require global or relative positioning information concerning agents and their neighbors. This alleviates the need for sensors which require calibration, are expensive and h ...

Active magnetic bearing design and characterization for high temperature applications

Luc Burdet

This thesis is motivated by one of the largest markets: aviation. This market, in which competition and investments are extraordinary, requires constant technical improvements in order to increase its competitiveness. Jet engines have an important influenc ...

CMOS magnetic sensors with integrated ferromagnetic parts

Radivoje Popovic, Pavel Kejik, Predrag Drljaca

The paper deals with Hall and flux-gate magnetic field sensors consisting of integrated combination of CMOS ASICs and planar ferromagnetic components. Ferromagnetic parts are made of a soft amorphous alloy, integrated at the CMOS wafer in a post-processing ...

Analytical modeling of the flux density in permanent magnet motors

Yves Perriard

This paper presents an analytical model for the calculation of the flux density in PM synchronous motors. Parallel and radial magnetization of surface-mounted magnets and finite permeability of the iron are taken into account. © 2006 IEEE. ...

Integrated fluxgate compass for portable applications

Predrag Drljaca

Modern applications in industry, navigation and medicine demand small and sensitive magnetic field sensors. In this thesis we have developed a new planar micro fluxgate magnetometer. High resolution, low power consumption and orthogonal fields detection ma ...

Effects of a vertical magnetic field on particle confinement in a magnetized plasma torus

Ambrogio Fasoli, Benoît Labit, Mario Ludovico Podesta, Francesca Maria Poli

The particle confinement in a magnetized plasma torus with superimposed vertical magnetic field is modeled and measured experimentally. The formation of an equilibrium characterized by a parallel plasma current canceling out the grad B and curvature drifts ...

2004

This research has been sponsored by the Centre Suisse d'Electronique et de Microtechnique (CSEM) in Neuchâtel, Switzerland. It introduces a system and the algorithms for Pedestrian Navigation using a combination of sensors. The main objective is to localis ...

EPFL2003

When satellite signals are available, the localisation of a pedestrian is fairly straightforward. However, in cities or indoors, dead reckoning systems are necessary. Our current research focuses on the development of algorithms for pedestrian navigation i ...
