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 dramatic increase in global atmospheric carbon dioxide over the past century is hypothesized to have significant impacts on the earth system. To understand the effects of elevated CO2 on terrestrial ecosystems, two main methods have been used to simula ...
We report on a new single-photon avalanche diode (SPAD) fabricated in a 130 nm CMOS imaging process. A novel circular structure combining shallow trench isolation (STI) and a passivation implant creates an effective guard ring against premature edge breakd ...
Network coding is a new research area that may have interesting applications in practical networking systems. With network coding, intermediate nodes may send out packets that are linear combinations of previously received information. There are two main b ...
Multimodal Routing Systems allow routing by different modes which is particularly interesting in urban environments. These systems are expected to be an important tool to encourage modal shift. They can only work, however, if people accept and use this tec ...
The traffic generated by multimedia applications presents a high degree of burstiness that can be hardly described by a static set of traffic parameters. The following paper presents a dynamic QoS negotiation scheme applied to a video streaming application ...
When tuning the smoothness parameter of nonparametric regression splines, the evaluation of the so-called degrees of freedom is one of the most computer-intensive tasks. In the paper, a closed-form expression of the degrees of freedom is obtained for the c ...
This chapter discusses the work carried out to establish the link between climate and atmospheric composition over the last million years, a period over which archives from different media offer precious information with a high degree of detail and accurac ...
Global data sets of the stable carbon isotope composition of plant leaves, of CO2 in canopy air, and of CO2 in the background atmosphere were compiled and compared to results of a global vegetation model (BIOME4) that simulated, at these three scales, the ...
Object of this work 1) Explore the feasibility of an LTCC microreactor • Chemical stability: compatible with HCl, NaOH, ... • Thermal stability to >100°C 2) Achieve a high degree of integration • Temperature measurement • Reactant flow measurement • Temper ...
