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 predictive capacity of a physically based snow model to simulate point-scale, subcanopy snowmelt dynamics is evaluated in a mixed conifer forest, southern Sierra Nevada, California. Three model scenarios each providing varying levels of canopy structur ...
The creation of wide-area real-time monitoring systems for the road network has the potential to achieve a step change in both, our understanding of the evolution of congestion and forecasting/information to minimise its economic consequences. While such c ...
In mountains the snow cover is heterogeneously distributed in space and time. The spatial and temporal variability of the Alpine snow cover has a major influence on avalanche danger, snow hydrology, mountain ecology and winter tourism. In winter, already d ...
Rockfall propagation areas can be determined using a simple geometric rule known as shadow angle or energy line method based on a simple Coulomb frictional model implemented in the CONEFALL computer program. Runout zones are estimated from a digital terrai ...
Light detection and ranging (LiDAR) has demonstrated its capabilities as a prominent technique for the direct acquisition of high density and accurate topographic information. To achieve the potential accuracy of such systems, a rigorous system calibration ...
This paper presents the derivation of surface-related quality indicators describing the confidence-metrics of the final geo-products de- rived from airborne laser scanning (ALS). We first discuss the number of factors influencing the qual- ity of the digit ...
The spatial modelling of extreme snow is important for adequate risk management in Alpine and high altitude countries. A natural approach to such modelling is through the theory of max-stable processes, an infinite-dimensional extension of multivariate ext ...
The maximization of the photon detection efficiency (PDE) is a key issue in the development of cameras for Imaging Atmospheric Cherenkov Telescopes. Geiger-mode Avalanche Photodiodes (G-APD) are a promising candidate to replace the commonly used photomulti ...
Impacts of climate change on winter tourism supply have attracted considerable scientific interest in recent years. In comparison, only few studies have addressed so far the effects on demand. In this article, we analyse how snow and weather conditions cur ...
