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.

Evaluating and Repairing Write Performance on Flash Devices

Anastasia Ailamaki, Frederick Ryan Johnson, Manoussos Gavriil Athanassoulis, Radu Ioan Stoica

In the last few years NAND flash storage has become more and more popular as price per GB and capacity both improve at exponential rates. Flash memory offers significant benefits compared to magnetic hard disk drives (HDDs) and DBMSs are highly likely to u ...

Scaling and dynamics of washboard roads

Anne-Florence Raphaëlle Bitbol

Granular surfaces subjected to forces due to rolling wheels develop ripples above a critical speed. The resulting pattern, known as washboard or corrugated road, is common on dry unpaved roads. We investigated this phenomenon theoretically and experimental ...

Implementing a P2P Social Network - Early Experiences and Insights from PeerSoN

Anwitaman Datta, Sonja Buchegger

To address privacy concerns in Online Social Networks (OSNs), we propose to use a distributed, peer-to-peer approach coupled with encryption. To verify the feasibility of such an approach, we designed a two-tiered architecture and protocols that recreate t ...

Porphyrin-based photocatalytic lithography

Jeffrey Alan Hubbell

Photocatalytic lithography couples light with photoreactive coated mask materials to pattern surface chemistry. We excite porphyrins to create radical species that photocatalytically oxidize, and thereby pattern, chemistries in the local vicinity. The tech ...

Working with extreme urban density: Hong Kong. A prototype of mixed-use building in Hong Kong

Joana Varela, Wing-Chung Cheung

Urban sprawl, a solution to house fast-growing metropolitan populations, dilutes the substance of cities and generates extensive uniformly built fabrics lacking structural poles of attraction. Hong Kong is one of the seldom exceptions of this general tende ...

Augmenting Astronaut's Capabilities through Brain-Machine Interfaces

José del Rocio Millán Ruiz

Brain-Machine Interfaces (BMIs) transform the brain activity of a human operator into executable commands that can be sent to a machine, usually a computer or robot, to perform intended tasks. In addition to current biomedical applications, available techn ...

Information-theoretic framework for unsupervised activity classification

Frédéric Kaplan

This article presents a mathematical framework based on information theory to compare multivariate sensory streams. Central to this approach is the notion of configuration: a set of distances between information sources, statistically evaluated for a given ...
