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.

Altitude: architecture et environnement de haute montagne

Estelle Lépine

At the centre of the research is the preservation of the countryside which is highlighted and studied through an architectural approach which focuses on cabins in the high mountains. The projects must reflect upon territorial, global and sustainable aspect ...

Imaging blood cells through scattering biological tissue using speckle scanning microscopy

Demetri Psaltis, Ye Pu, Xin Yang

We demonstrate imaging of blood cells enclosed in chicken skin tissue using speckle scanning microscopy (SSM). Clear images of multiple cells were obtained with subcellular resolution and good image fidelity, provided that the object dimension was smaller ...

Détroit: reconstructions. Une urbanisation de la ruine, Detroit Downtown, USA

Olivier Di Giambattista, Joachim Nils Fritschy

Après des décennies flamboyantes suivies d'une longue agonie post-industrielle, Motorcity est officiellement en faillite. La métropole du Michigan est en ruine financièrement et sa spatialité s'effondre. Les bâtiments abandonnés et pillés jonchent le parce ...

We propose and experimentally demonstrate an all-optical Nyquist sinc-shaped pulse train source based on intensity modulation and four-wave mixing. The proposed scheme allows for the tunability of the bandwidth and the full flexibility of the repetition ra ...

Optical Society of America2014

This paper evaluates the performance of national higher education systems in 48 countries as measured with 20 variables grouped under the four headings of Resources, Environment, Connectivity and Output. Rankings within each module are then combined into a ...

Optical characterization of two-dimensional array of 2048 tilting micromirrors for astronomical spectroscopy

Nico de Rooij, Michael David Canonica, Wilfried Noell

A micromirror array composed of 2048 silicon micromirrors measuring 200 x 100 mu m(2) and tilting by 25 degrees was developed as a reconfigurable slit mask for multi-object spectroscopy (MOS) in astronomy. The fill factor, contrast, and mirror deformation ...

Monte Carlo simulation of the field back-scattered from rough surfaces

Christian Depeursinge, Yves Delacrétaz, Stéphane Chamot

A novel approach for the simulation of the field back-scattered from a rough surface is presented. It takes into account polarization and multiple scattering events on the surface, as well as diffraction effects. The validity and usefulness of this simulat ...

Probable zoonotic leprosy in the southern United States

Stewart Cole, Jacques Rougemont, Rahul Sharma, Philippe Busso, Adamantia Kapopoulou, Pushpendra Singh

In the southern region of the United States, such as in Louisiana and Texas, there are autochthonous cases of leprosy among native-born Americans with no history of foreign exposure. In the same region, as well as in Mexico, wild armadillos are infected wi ...

Tuning Mechanisms in Optofluidics

Demetri Psaltis, Wuzhou Song, Jae-Woo Choi

Novel functionalities have been developed through the fusion of optics and microfluidics. We categorize the different possible tuning mechanisms in optofluidics and describe the recent examples in each category. (C)2010 Optical Society of America ...
