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.
Even if supercapacitors present a reduced energy density, they allow to store a significant amount of energy which leads to a significant autonomy for applications with reduced energy needs. The main advantage of supercapacitors is to compensate a limited ...
The strategy document « Vision Energétique de la Suisse en 2050 », established by the Center for Energy Policy and Economics of Swiss Federal Institute of Technology (ETHZ), reveals the first impacts of climate change and underlines the fact, that the incr ...
Energy-harvesting sensor nodes (EHSNs) have stringent low-energy consumption requirements, but they need to concurrently execute several types of tasks (processing, sensing, actuation, etc). Furthermore, no accurate models exist to predict the energy harve ...
Water and energy are the key resources required for both economic and population growth, and yet both are increasingly scarce. The distribution of water takes large amounts of energy, while the production of energy requires large amounts of water in proces ...
Thermal soaring saves much energy, but flying large distances in this form represents a great challenge for birds, people and unmanned aerial vehicles (UAVs). The solution is to make use of the so-called thermals, which are localized, warmer regions in the ...
The Master Project offers a survey on several aspects of co-digestion in wastewater treatment plants (WWTP) and in agriculture. The description of the legal context and the technical processes present the basis for the subsequent analysis of the co-digesti ...
The modulation of the electronic structure of cobalt islands on Cu(111) by the Moire pattern of an Ag overlayer is investigated. Acquisition of tunneling spectroscopy maps reveals a local modification of both the energy and the amplitude of the cobalt-rela ...
This study concentrates on determining how to implement the legal framework at different institutional levels in an integrated approach for the planning and management of energy systems in urban areas. There are mainly five levels of decision able to influ ...
An innovative subway has been proposed using supercapacitors as energy source. In this paper, are presented different possibilities to reduce on-board stored energy in order to downsize the on-board energy storage subsystem. Special attention is paid to th ...
This paper presents an approach to design a contactless energy transfer system to supply desktop computer peripherals. Energy is transferred using coreless transformers from an array of primary coils (placed on a table) to one or several secondary coils (p ...
