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.

The link between the infinite mapping class group of the disk and the braid group on infinitely many strands

Jan Brunner

φ For all finite n ∈ N, there is a well-known isomorphism between the standard braid group Bn and the mapping class group π0Hn. This isomorphism has been exhaustively studied in literature, and generalized in many ways. For some basic topological reason, t ...

Evaluation of bamboo for building elements satisfying housing criteria

David Javier Guzman Chavez

Bamboo – identified as a Non Timber Forest Product (NTFP) – offering optimal mechanical properties for construction purposes, and at the same time little studied among contemporary building materials, is paradoxically most used in precarious housing. The u ...

An active connection mechanism for modular self-reconfigurable robotic systems based on physical latching

Auke Ijspeert, Masoud Asadpour, Yvan Bourquin

This article presents a robust and heavy duty physical latching connection mechanism, which can be actuated with DC motors to actively connect and disconnect modular robot units. The special requirements include a lightweight and simple construction provid ...

Hierarchical Penalization

Hierarchical penalization is a generic framework for incorporating prior information in the fitting of statistical models, when the explicative variables are organized in a hierarchical structure. The penalizer is a convex functional that performs soft sel ...

Identification of PieceWise Affine Models of Genetic Regulatory Networks: the Data Classification Problem

Giancarlo Ferrari Trecate

In this paper we consider the identification of PieceWise Affine (PWA) models of Genetic Regulatory Networks (GRNs) and focus on data classification that is a task of the whole identification process. By assuming that gene expression profiles have been spl ...

Advances in the Design and Implementation of Group Communication Middleware

André Schiper, Sergio Mena, Olivier Rütti, Rachele Fuzzati, Daniel Bünzli

Group communication is a programming abstraction that allows a distributed group of processes to provide a reliable service in spite of the possibility of failures within the group. The goal of the project was to improve the state of the art of group commu ...

Orbit equivalence rigidity and bounded cohomology

Nicolas Monod

We establish new results and introduce new methods in the theory of measurable orbit equivalence. Our rigidity statements hold for a wide (uncountable) class of negatively curved groups. Amongst our applications are (a) measurable Mostow-type rigidity theo ...

Drug loading of porous coating

Heinrich Hofmann, Laurent-Dominique Piveteau

Porous coating for the controlled release of drugs, said coating comprising a porous structure with pores adapted to act as reservoirs or as passages for a drug, in such a way that said drug can move from the external environment to/from or through said po ...

Autonomous Self-assembly in a Swarm-bot

Francesco Mondada, Michael Bonani, Roderich Gross

Multi-robot systems have been studied in tasks that require the robots to be physically linked. In such a configuration, a group of robots may navigate a terrain that proves too difficult for a single robot. On the contrary, many collective tasks can be ac ...
