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.
In current biological and biomedical research, quantitative endpoints have become an important factor of success. Classically, such endpoints were investigated with 2D imaging, which is usually destructive and the 3D character of tissue gets lost. 3D imagi ...
The instrument VOLPE (volume photoemission from solids) is an experimental setup dedicated to high energy photoemission (PE) experiments. The instrument is equipped with an electrostatic hemispherical spectrometer especially designed to analyze high energy ...
According to various studies, Grain Boundary Engineering (GBE) is likely to enhance mechanical properties of polycrystalline materials. The present investigation highlights some relationships between thermomechanical process (TMP) parameters of a commercia ...
The solidification of an aluminum-copper alloy has been simulated in 3D using a granular model. Compared to previous similar 2D approaches for where only one phase is continuous, the extension to 3D allows for concurrent continuity of the solid and liquid ...

This article widens the scope of the cell-transmission model (CTM) to the modeling of urban traffic, which is dominated by intersection dynamics. The CTM has originally been proposed for freeways, and it is not immediately applicable to urban traffic for t ...
Seit nunmehr 18 Monaten hat der Lehrstuhl für Holzkonstruktionen der EPFL, der 27 Jahre lang von Prof. Natterer geführt wurde, einen neuen Leiter und damit eine neue Forschungsrichtung: "New Modeling" - neue Wege der Formfindung durch interdisziplinäre Zus ...
Nanostructured materials should present a good resistance to irradiation because the large volume fraction of grain boundaries can be an important sink for radiation-induced defects. The objective of the present study is to experimentally investigate the i ...
For the patterning on 'unconventional' surfaces and/or non-IC applications new micro- and nanopat- terning technologies are developed. One of these techniques is the localized material deposi- tion through ultra-miniature shadow masks (nanostencils). Nanos ...
The effect of the bulk microstructure (grain size distribution, grain boundary length) on the oxygen transport properties of permeation membranes is investigated in this work. For this purpose, La0.5Sr0.5FeO3-? samples with different microstructures have b ...
The characteristics of synchrotron X-ray sources-quite different from those of conventional sources-are exploited by several new imaging techniques. These techniques expand the capabilities of conventional radiology and find interesting application in spec ...
