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.
Large scale energy storage may play an increasingly important role in the power generation and distribution sector, especially when large shares of renewable energies will have to be integrated into the electrical grid. Up to now pumped-hydro is the only t ...
The main objective of this theoretical study was to investigate under which conditions a magnetic energy conversion device (MECD) - utilizing industrial waste heat - is economically feasible. Furthermore, it was evaluated if magnetic energy conversion (MCE ...
The interest in energy storage is currently increasing, especially from the perspectives of matching intermittent sources of renewable energy with customer demand and storing excess nuclear or thermal power during the daily cycle. Technologies to be consid ...
Nowadays many consumer electronic devices are using small engines (micromotors). Thanks to technological innovation, the components can be imbedded into numerous portable systems. The key factors for a nomadic integration are: reduction of power consumptio ...
This paper analyses the thermodynamic performance and proposes different energy integration schemes for a methanol absorption based acid gas removal process, namely the Rectisol® process specifically designed for the selective removal of H2S and CO2 from c ...
We present a multisensor designed for industrial compressed air diagnostics and combining the measurement of pressure, flow, and temperature, integrated with the corresponding signal conditioning electronics in a single low-temperature co-fired ceramic (LT ...
The progress in the technology of microelectronic devices has led to a strong miniaturization and high performance for circuits and systems, enabling modern applications such as mobile computing and communications. Today, remaining "off-chip" components th ...
Functional Magnetic Resonance Imagery (fMRI) is an imaging technique allowing the observation of brain activity. Haptic interfaces can be used in conjunction with fMRI to stimulate the subject while measuring brain activity. Using robotic stimulation over ...
In this work we establish novel analytical and small signal circuit modeling of two major effects that co-exist in active Micro-Electro-Mechanical resonators: charge and piezoresistance modulations. Analytical expressions for the output current of vibratin ...
An Implantable delivery device comprising at least a body (1), an inlet (2 17 46) and an outlet (3 18 47) and actuating means, wherein the actuating means comprise at least an actuator displacing a piston (6 21 32) in a rotating cylinder (4 19 31) forming ...
