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.

Examples of algebraic groups of type G (2) having the same maximal tori

Ting-Yu Lee

Answering a question of A. Rapinchuk, we construct examples of non-isomorphic semisimple algebraic groups H (1) and H (2) of type G (2) having coherently equivalent systems of maximal k-tori. ...

Flexure-based multi-degrees-of-freedom in-vivo force sensors for medical instruments

Simon Nessim Henein, Charles Baur, Marine Chantal Elisabeth Geneviève Clogenson, Sebastian Krzysztof Fifanski, José Luis Rivera Gutiérrez

This paper presents novel multi-degrees-of-freedom force sensors based on flexures used as mecano-optical transducers (named flexure body) and white light interferometers used as opto-electrical transducers. Together, these transducers make up a load cell ...

Low temperature integration methods using conductive adhesives and dry film photoresist for flexible electronics

Andres Felipe Vasquez Quintero

This thesis provides reliable methods and building blocks in order to realize smart SiF by combining Si- with foil-based components on flexible substrates. Building blocks such as 2-D and 3-D electrical interconnections, hybrid integration techniques and e ...

Implantable and wearable measurement system for smart knee prosthesis

Kamiar Aminian, Philippe Renaud, Arash Arami, David Forchelet

In this work we present the implantable and wearable measurement system developed for smart knee prostheses monitoring. The kinematic measurement system contains three anisotropic magnetoresistive sensors embedded into the polyethylene part of the prosthes ...

Robust H-infinity Controller Design Using Frequency-Domain Data

Alireza Karimi, Yuanming Zhu

A new robust controller design method is developed for linear time-invariant single-input single-output systems presented by their frequency response data. The performance specifications are in terms of the upper bounds on the infinity norm of weighted clo ...

The kilogram is the last unit of the international system of units (SI) still based on a material artefact, the international prototype of the kilogram (IPK). The comparisons made in the last hundred years have clearly revealed a long-term relative drift b ...

Architecture potentielle (Jonction, Genève)

Pauline Seigneur

“Fait frais ici non? Faut dire qu'on est presque à la campagne et puis y a l'eau… quand ils ouvrent les vannes en amont, ici t'as les pieds dans l'eau. J'venais souvent ici avant y avait moins de constructions, plus de terrains vagues…T'étais déjà venu? On ...

Convolutional Pitch Target Approximation Model for Speech Synthesis

Philip Neil Garner

In this paper, we investigate pitch contour modelling in speech synthesis based on segmental units. A convolutional pitch target approximation model is proposed. This model allows jointly stochastic modelling of framewise pitch and pitch contour of longer ...

Système de conversion d'énergie

Yves Perriard, Paolo Germano, Christophe Bruno Auvigne

The system (20) has a switching unit (T1) adapted for switching reversibly between two configurations. A capacitor is connected in series between a secondary winding (9) and a connection terminal (A) in one of the configurations. Another capacitor is conne ...
