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.

Yacora on the Web: Online collisional radiative models for plasmas containing H, H-2 or He

Maurizio Giacomin

Yacora on the Web (www.yacora.de ) is a web application providing access to collisional radiative models based on the flexible solver Yacora. The main application range is plasma diagnostics in low-pressure plasmas. Available online are three collisional r ...

Blocked radiative heat transport in the hot pyrolitic lower mantle

James Badro, Farhang Nabiei, Hélène Marie Piet

The heat flux across the core-mantle boundary (Q(CMB)) is the key parameter to understand the Earth's thermal history and evolution. Mineralogical constraints of the Q(CMB) require deciphering contributions of the lattice and radiative components to the th ...

Impact of defects on Auger recombination in c-plane InGaN/GaN single quantum well in the efficiency droop regime

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Yixing Chen, Gwénolé Jean Jacopin, Wei Liu, Camille Haller, Thomas Fjord Kjaersgaard Weatherley

We study the impact of non-radiative defects on Auger recombination in c-plane InGaN/GaN single quantum wells (SQWs) in the efficiency droop regime using high injection time-resolved photoluminescence. The defect density in the SQW is controlled by tuning ...

Finding pragmatic solutions to curb the accumulation of atmospheric CO2 and tackle the associated greenhouse effect is challenging. Herein, we demonstrate the use of an in situ formed frustrated Lewis pair (FLP) within a metal-organic framework (MOF) to ef ...

The development of material flow analysis (MFA) on large-scale systems is challenging due to the complexity and breadth of data that are required and the magnitude of the mass flows involved. This is true, for example, when trying to determine the material ...

Paul Scherrer Institute, World Resources Forum2019

Greenhouse gas measurements along polar ice cores provide important insight into the former composition of the atmosphere, its natural variations, and the responses to fast climatic changes in the past. We present high-resolution nitrous oxide (N2O) and me ...

ODes aCCSES Report: Optimal design and control of cruise ship energy systems

Francesco Baldi

Reducing global emissions of greenhouse gases while promoting social and economicdevelopment is one of the toughest challenges ever faced in the history of human kind.This challenge is affecting all sectors of human activities: process plants, land-basedtr ...

Carbon dioxide capture, storage and production of biofuel and biomaterials by bacteria: A review

Edgard Gnansounou, Manish Kumar

Due to industrialization and urbanization, as humans continue to rely on fossil fuels, carbon dioxide (CO2) will inevitably be generated and result in an increase of Global Warming Gases (GWGs). However, their prospect is misted up because of the environme ...

Global and local anthropogenic effects on hydrodynamics of lakes

Carl Love Mikael Råman Vinnå

In many countries water quality is a major concern for drinking water management authorities. Freshwater is a limited resource and the demand for good-quality water from natural aquatic systems is therefore high. Additional stress arises from anthropogenic ...

Investigation of snow melt dynamics and boundary layer processes over a melting snow surface

Sebastian Schlögl

In this thesis, we investigate the surface energy balance of a snow pack for a continuous and a patchy snow cover. Snow surface temperatures have been validated to assess the accuracy of the surface energy balance of a continuous snow pack for individual p ...
