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.
The formulation describing the electromagnetic field radiated by a lightning return stroke over a two-layered conducting ground is presented in this paper. The derivation of the Green's functions required to solve the problem is first discussed in detail, ...
Common indicators used to examine the potential for utilising natural radiation of urban forms include the sky view factor (V-s), the height to width ratio and the urban horizon angle. These indicators are conveniently related to one another. In comparing ...
The sensitivity of microelectromechanical system (MEMS) devices to radiation is reviewed, with an emphasis on radiation levels representative of space missions rather than of operation in nuclear reactors. As a purely structural material, silicon has shown ...
The sensitivity of MEMS devices to radiation is reviewed, with an emphasis on radiation levels representative of space missions. While silicon and metals generally do not show mechanical degradation at the radiation levels encountered in most missions, MEM ...

Optoelectronic measuring apparatus comprising emitting means suitable, in use, to generate and modulating the optics power of a plurality of trains comprising a plurality of first electromagnetic pulses presenting a first given frequency and a first durati ...
The paper reviews some popular techniques to harvest energy for implantable biosensors. For each technique, the advantages and drawbacks are discussed. Emphasis is placed to the inductive links, able to deliver power wirelessly through the biological tissu ...

A focus-detector arrangement of an X-ray apparatus is disclosed for generating projective or tomographic phase contrast recordings of an observed region of a subject. In at least one embodiment, the arrangement includes a radiation source which emits a coh ...
The electromagnetic effects of a High Altitude EMP has been a threat for communications and installations which has been largely studied and documented between 1960 and 1990. During the last decade of the 20(th) century, a new kind of electromagnetic field ...
