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 project High Temperature Heat Pump has been completed in 2 phases. First a new type of scroll compressor with adapted injection port for vapor injection, was tested with an air-water heat pump (fig 2.2, 2.3). This type of heat pump reaches the extreme ...
A new technique is presented for the prepn. of DSA type electrodes. In this technique, the precursor is rapidly decompd. on the substrate by treatment in an induction electromagnetic field. The effects of the rapid heating of H2IrCl6.6H2O precursor on Ti s ...
Dynamical chaos is produced by the interaction between plasma particles and two electrostatic waves. Experiments performed in a linear magnetized plasma and a ID particle-in-cell simulation agree qualitatively: above a threshold wave amplitude, ion stochas ...
A complex heating and cogeneration plant including two 3.9 MWth ammonia heat pumps and two 3 MWel gas turbines with heat recovery boilers and three storage tanks of 66 GJ has been in operation since 1986. The heating surface is actually about 280’000 m2 an ...
In this work, a parametric study is done with computational methods for groundwater flow and heat transport in order to describe the dominant physical phenomena in an Aquifer Thermal Energy Storage (ATES). Optimum operating conditions and geological parame ...
The concept of (shear) Alfvèn wave resonant absorption for heating a plasma has been demonstrated on a theta pinch. The m = 1 mode is excited by means of a helical launching structure with a given wave length, at different frequencies. When the frequency i ...
Diols, meso- and dl-PrCH(OH)CH(OH)Pr, cis- and trans-1,2-cyclohexanediol, 9,10,-cis-dihydroxy-cis,trans-1,5-cyclododecadiene, trans-7,8-dihydroxybicyclo[4.2.0]octane, and I, are epimerized by heating their dilithium diolates in (MeOCH2CH2)2O in 55-78% yiel ...
Five bonds form in one pot, from three well-designed yet readily accessible substrates. Simply mixing an o-alkynyl aniline, e.g., 2-H2NC6H4C==CCO2Me, an aldehyde, e.g., heptanal, and ammonium chloride in toluene at room temp., followed by addn. of an isocy ...
Particle and energy losses due to type-I edge-localized modes (ELMs) and the effect of H-mode pedestal parameters on global confinement are studied for H-Mode discharges in ASDEX Upgrade. ELM frequency as well as particle and heat losses during ELMs are st ...
