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.

NCO Tracking for Singular Control Problems Using Neighboring Extremals

Dominique Bonvin, Benoît Chachuat, Sébastien Gros

A powerful approach for dynamic optimization in the presence of uncertainty is to incorporate measurements into the optimization framework so as to track the necessary conditions of optimality (NCO), the so-called NCO- tracking approach. For nonsingular co ...

Design status of ITER ECH upper launcher mirrors

René Chavan, Jean-Daniel Landis, Francisco Sanchez, Robert Bertizzolo, Joseph Duron

The ITER ECH upper launcher is devoted to directing up to 8 2NM beams per port plug over half of the plasma cross section. A focusing mirror is used to achieve a very narrow deposition profile to stabilize MHD activity such as the neoclassical tearing mode ...

A 1.5g SMA-actuated Microglider looking for the Light

Dario Floreano, André Guignard, Mirko Kovac, Jean-Daniel Nicoud, Jean-Christophe Zufferey

Unpowered flight can be used in microrobotics to overcome ground obstacles and to increase the traveling distance per energy unit. In order to explore the potential of goal-directed gliding in the domain of miniature robotics, we developed a 22cm microglid ...

Omnidirectional Active Vision for Evolutionary Car Driving

Dario Floreano, Mototaka Suzuki, Jacob Van der Blij

We describe a set of simulations to evolve omnidirectional active vision, an artificial retina scanning over images taken via an omnidirectional camera, being applied to a car driving task. While the retina can immediately access features in any direction, ...

An alternative ECRH front steering launcher for the ITER upper port

René Chavan, Francisco Sanchez

Presently, a remote steering (RS) antenna [C.P. Moeller, A method of remotely steering a microwave beam launched from a highly overmoded corrugated waveguide, in: Proceedings of the 23rd International Conference on IRMMW, Colchester, UK, 1998] is envisione ...

Immersive vehicle simulators for prototyping, training and ergonomics

Daniel Thalmann

In most vehicle simulators, complete physical mockups equipped with steering wheel, gearshift and pedals are required. These devices are essential in trying to simulate real conditions, but as a drawback the system becomes expensive, huge (non mobile), and ...

Vehicle for rugged terrain

Roland Siegwart, Michel Lauria

The invention concerns a vehicle whereof the rigid body (1, 2, 4) comprises the front element (20) forming the rear element of a deformable articulated quadrilateral (17, 18, 19, 20). The element (17) is mounted in the extension of the arm (15) linked to t ...

Liquid crystal on silicon beam deflector

Demetri Psaltis, Xiao Wang

A high efficiency, low cost, low voltage operation liquid crystal on silicon (LCOS) beam steering device with multiple angles addressing capability is developed. Currently, seven steering angles with as high as 92.7% efficiency are achieved within 2.85v. T ...
