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.

Decentralizing the Cloud: How Can Small Data Centers Cooperate?

Karl Aberer, Rameez Rahman, Hao Zhuang

Cloud computing has become pervasive due to attractive features such as on-demand resource provisioning and elasticity. Most cloud providers are centralized entities that employ massive data centers. However, in recent times, due to increasing concerns abo ...

Using semi-open questions to integrate perceptions in choice models

Michel Bierlaire, Aurélie Glerum, Bilge Atasoy

This research investigates the measurement of perceptions by means of adjectives freely reported by respondents in semi-open questions. It involved the use of semi-open responses of 1'763 Swiss individuals to develop indicators for a latent variable repres ...

Why glass elasticity affects the thermodynamics and fragility of supercooled liquids

Matthieu Wyart

Supercooled liquids are characterized by their fragility: The slowing down of the dynamics under cooling is more sudden and the jump of specific heat at the glass transition is generally larger in fragile liquids than in strong ones. Despite the importance ...

Phonon gap and localization lengths in floppy materials

Matthieu Wyart

Gels of semi-flexible polymers, network glasses made of low valence elements, softly compressed ellipsoid particles and dense suspensions under flow are examples of floppy materials. These systems present collective motions with almost no restoring force. ...

Validating models for disease detection using twitter

Marcel Salathé

Data mining social media has become a valuable resource for infectious disease surveillance. However, there are considerable risks associated with incorrectly predicting an epidemic. The large amount of social media data combined with the small amount of g ...

Using semi-open questions to integrate perceptions in choice models

Michel Bierlaire, Aurélie Glerum, Bilge Atasoy

This research investigates the measurement of perceptions by means of adjectives freely reported by respondents in semi-open questions. The objective of this work is to use these adjectives as indicators of perceptions in hybrid choice models (HCM) in orde ...

On the price elasticity of demand for patents

Gaétan Jean A de Rassenfosse

This paper provides an analysis of the impact of patent fees on the demand for patents. It presents a dataset of fees since 1980 at the European (EPO), the US and the Japanese patent offices. Descriptive statistics show that fees have severely decreased at ...

Analytical approximations for the collapse of an empty spherical bubble

Mohamed Farhat, Danail Obreschkow

The Rayleigh equation 3/2 (R) over dot + R(R) double over dot + p rho(-1) = 0 with initial conditions R(0) = R-0, (R) over dot(0) = 0 models the collapse of an empty spherical bubble of radius R(T) in an ideal, infinite liquid with far-field pressure p and ...

Deep Habits, Price Rigidities and the Consumption Response to Government Spending

This paper inspects the 'deep' habits mechanism originally used by Ravn, Schmitt-Grohé and Uribe (2006) to generate the positive comovement of public and private consumption observed in many VAR studies. In their set-up, the price-elasticity of demand is p ...

The Optima project: inferring transport mode preferences from attitude

Michel Bierlaire, Aurélie Glerum, Bilge Atasoy, Antonin Danalet, Anne Curchod

Objectives, data collection, model estimation, elasticities, value of time and validation in the context of the Optima project, a collaborative work between EPFL’s Transportation Center (TraCe) and CarPostal, the public transport branch of the Swiss Postal ...
