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.
For more than two decades, Mars has been of great interest for scientific exploration, using orbiting spacecrafts or landers. Orbiters like Mars Express cover large areas and give images of the surface with a resolution limited to several meters. Rovers ...
Energy storage systems can be considered today as new means to adapt the variations of the power demand to the given level of power generation. In the context of the use of Renewable Energies or other distributed power generation, they can be used also as ...
During recent years the European Space Agency (ESA) has started to develop concepts for micro-rovers for planetary missions. An ESA Technology Research Program (TRP) activity "Micro-Robots for Scientific Applications" has been dedicated to this subject. Wi ...
Development of unmanned aerial vehicle has attracted attention of several agencies and university laboratories over the past decade, due to their great potential in military and civilian applications. There are a dozen of commercial autopilots which combin ...
Rough terrain robotics is a fast evolving field of research and a lot of effort is deployed towards enabling a greater level of autonomy for outdoor vehicles. Such robots find their application in scientific exploration of hostile environments like deserts ...
We propose a robust and low complexity scheme to estimate and track carrier frequency from signals traveling under low SNR conditions in highly non-stationary channels. These scenarios arise in planetary exploration missions subject to high dynamics, such ...
A new feeding concept for electrical transportation system is presented, based on supercapacitative energy storage. Supercapacitors are new and poewrful components for energy storage. Compared with batteries, the amount of energy supercapacitors can store ...
Supercapacitors are components for energy storage. Due to their series resistors, the energy efficiency of supercapacitors can be low. In this paper, the unloading of supercapacitors with constant current and power are studied, to identify and take into ac ...
In the context of a sustainable development the optimal use of the electrical energy will require advanced networks allowing interconnections on very long distances and addressing the storage challenge. These requirements are essentially due to the followi ...
In the current economic situation regarding electric generation and conservation of the environment, it is essential to develop sustainable technologies. From this point of view, hydropower is an excellent resource with a consequently high value. The syste ...
