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.
Many fundamental processes that govern the function of biological cells occur on or immediately under the cell membrane. Fluorescence marking of specific sites has had a large impact in the recognition of these processes. In addition, observation in an app ...
First-principles molecular dynamics simulations at constant pressure have been used to investigate the mechanisms of compression of liquid SiO2. Liquid SiO2 is found to become denser than quartz at a pressure of about 6 GPa, in agreement with extrapolation ...
Monolayers of gramicidin A, pure and in mixts. with dimyristoylphosphatidylcholine (DMPC), were studied in situ at the air/H2O and air/D2O interfaces by polarization-modulated IR reflection absorption spectroscopy (PM-IRRAS). Simulations of the entire set ...
The setting level of a hydraulic machine, specially for low head machines, is decided with respect to the possible alteration of the efficiency due to the cavity development. This alteration can easily be noticed by following the evolution of the efficienc ...
An experimental study of flow in a Francis hydraulic turbine, especially designed for the GAMM Workshop, has been carried out. In order to provide a data base for the validation and comparison of computational fluid dynamics codes, a Francis turbine mode! ...
The use of microbalances to study gas-solid reactions at high temps. and normal pressure is often limited by fluctuations due to thermal convection in the reaction zone. The fluctuations depend on the pressure, the type of gas, the temp., and the geometry ...
We present a new experimental set-up for studying minerals by Raman spectroscopy in-situ at simultaneously high pressures (up to 35 GPa) and high temperatures (up to 2000 K). High pressures are generated with a diamond anvil cell and local sample heating i ...
The direct piezoelectric effect in fine and coarse grain barium titanate ceramics is examined as a function of the external alternating and static pressure. It is found that domain wall vibrations contribute to the piezoelectric effect in both types of cer ...
Experimental flow analysis of hydraulic machines is of prime importance for improving the design of such a unit. Moreover, computational fluid dynamics codes need an experimental data reference in order to check their ability to simulate the main flow feat ...
