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.

In 1851 Léon Foucault created a sensation with his pendulum providing a direct demonstration of the turning of the Earth. This simple device consists of a pendulum which is launched in a purely planar orbit. Following Mach's principle of inertia, the mass ...

We designed and tested a device to stimulate specifically one photoreceptor type, or a combination of some of them, of the human eye by using up to six primaries. The device produces a homogeneous light field over 40 degrees which is projected onto the ret ...

The Foucault pendulum is a well-known mechanism used to demonstrate the rotation of the Earth. It consists in a pendulum launched on linear orbits and, following Mach’s Principle, this line of oscillation will remain fixed with respect to absolute space bu ...

Typical flexure-based XY-stages have a serial design, and their layout results in the flexures being loaded in flection in face of heavy payloads or vertical loads. This paper presents a design with zero parasitic shift in which all flexures are loaded in ...

The Foucault pendulum provides a demonstration of the turning of the Earth. The principle at work is that linear oscillations of a two-degree-of-freedom isotropic harmonic oscillator remain unchanged in an inertial frame of reference, so appear to precess ...

The flywheel is a widespread mechanical component used for the storage of kinetic energy and angular momentum. It typically consists of cylindrical inertia rotating about its axis on rolling bearings, which involves undesired friction, lubrication, and wea ...

Flexure mechanism (1) comprising:- an end effector (3) arranged to be able to move in a first plane (XY);- an intermediate stage (7) linked to said end effector (3) by means of at least three first beams (5) extending substantially perpendicular to said fi ...

À l'origine, le but du tourbillon était d'améliorer la chronométrie d'une montre de poche en moyennant ses positions verticales. Avec I'avènement de la montre-bracelet, le tourbillon est prisé plus pour la prouesse technique de sa réalisation que pour sa f ...
