Graph Chatbot
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.
During the design of CAMEA extensive simulations and cinematic calculations were performed to explore the waste parameter space. These have led to a far better understanding of the instrument performance as well as new ideas to improve the instrument. Many ...
Most current imaging instruments have a spatially variant point spread function (PSF). An optimal exploitation of these instruments requires to account for this non-stationarity. We review existing models of spatially variant PSF with an emphasis on those ...
The Affinity Map is a project founded by the ENAC whose aim is to provide an instrument to understand organizations. The photograph shows the disclosure of the first map for the ENAC Research Day. The visualization was presented to scholars who are display ...
We propose the construction of a highly innovative spectrometer – CAMEA – offering Continuous Angular and Multiple Energy Analysis. Combining indirect time-of flight with multiple consecutive analyser arrays, this instrument will provide massive flux on th ...
Large shareholders may play an important role for firm performance and policies, but identifying this empirically presents a challenge due to the endogeneity of ownership structures. We develop and test an empirical framework that allows us to separate sel ...
The Santis Tower was instrumented in May 2010 and, to this date, more than 400 flashes were successfully recorded. Lightning current waveforms and their time-derivatives are measured at two different heights along the tower (24-m and 82-m AGL). In this pap ...
This paper presents an approach to study droplet activation kinetics from measurements of CCN activity by the Continuous Flow Streamwise Thermal Gradient CCN Chamber (CFSTGC) and a comprehensive model of the instrument and droplet growth. The model, which ...
CAMEA is a new instrument concept so it is possible that the construction could or maintenance of the instrument would be hampered by technical details. In order to prevent this a technical predesign have been performed. This is not a final technical solut ...
CAMEA is a novel instrument concept, thus the performance has not been explored. Furthermore it is a complex instrument using many analyser arrays in a wide angular range. The performance of the instrument has been studied by use of three approaches: McSta ...
We discuss the methods employed to photometrically calibrate the data acquired by the Low Frequency Instrument on Planck. Our calibration is based on a combination of the orbital dipole plus the solar dipole, caused respectively by the motion of the Planck ...
