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 theory of resonant Rayleigh scattering of light by excitons in a disordered quantum structure is presented. Disorder is modeled by a random Gauss distributed potential with finite correlation length in space. The time dependent scattered si,anal under ...
On the basis of experimental studies on the influence of the test head and the water nuclei content on the performance of a Francis turbine, we have shown that outlet cavitation is influenced by the active nuclei content of the test loop water. Numerical s ...

During these last decades, air pollution has drawn the attention of scientists because of the deterioration of the human environment that it has caused. Unfortunately, the study of this dynamic phenomenon is very complex and requires the use of models that ...
A new lidar for the measurement of tropospheric ozone is proposed, based on the differential analysis of the Raman backscattered signals on nitrogen and oxygen, which is far less sensitive to the aerosols than the classical DIAL system. Using a third Raman ...
Low pressure CVD of Cu from its bis-hexafluoroacetylacetonate was studied on oxidized Si substrates locally seeded with a 2.5 .ANG. Pt prenucleation film. ...
Mixts. of methane, H, and Ar (CH4:H2:Ar) were studied as UV Raman shifters for ozone differential absorption lidar application. They have higher photochem. stability than pure CH4 and the capability to produce, with high enough efficiency, either 1st CH4 S ...
