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.

Self-organization of Bio-inspired Integrated Circuits

Joël Rossier

Self-organizing circuits are able to grow, to self-replicate, and to self-repair. These properties are implemented in hardware thanks to configuration, cloning and cicatrization mechanisms. They are realized by the control layer of the POEtic tissue, a dat ...

Detecting queues at vending machines: a statistical layered approach

Jean-Marc Odobez

In this report, a method for monitoring activity at a ticket machine is presented. While this work has been done in the specific context of Turin metro, the proposed model could be applied to other locations and tasks in video-surveillance. Monitoring the ...

Techniques for Fully Integrated Intra-/Inter-chip Optical Communication

Edoardo Charbon, Claudio Favi

In this paper we propose to eliminate all data and control pads generally present in conventional chips and to replace them with a new type of ultra-compact, low power optical interconnect implemented almost entirely in CMOS. The proposed scheme enables en ...

OS-Based Sensor Node Platform and Energy Estimation Model for Health-Care Wireless Sensor Networks

Giovanni De Micheli, David Atienza Alonso, Francisco Javier Rincon Vallejos

Accurate power and performance figures are critical to assess the effective design of possible sensor node architectures in Body Area Networks (BANs) since they operate on limited energy storage. Therefore, accurate power models and simulation tools that c ...

A virtual 3D mobile guide in the INTERMEDIA project

Daniel Thalmann, Xavier Righetti, Achille Peternier

In this paper, we introduce a European research project, interactive media with personal networked devices (INTERMEDIA) in which we seek to progress beyond home and device-centric convergence toward truly user-centric convergence of multimedia. Our vision ...

Cooperative media streaming using adaptive network compression

Tom Larsen

Media content distribution constitutes a growing share of the services on the Internet. Two distinct distribution approaches used today are Layered Coding (LC) and Multiple Description Coding (MDC). Current wireless connection technologies, e.g. Wimax, hav ...

Analysis of brillouin-based distributed fiber sensors using optical pulse coding

We propose the use of pulse Simplex-coding in distributed temperature sensors based on spontaneous Brillouin scattering. The analysis shows achieved performance improvement and the effect on stimulated Brillouin threshold, resulting in lower required input ...

Route choice modeling with network-free data

Michel Bierlaire, Emma Frejinger

Route choice models are difficult to design and to estimate for various reasons. In this paper we focus on issues related to data. Indeed, real data in its original format are not related to the network used by the modeler and do therefore not correspond t ...

Collaborative wideband sensing for cognitive radios

Ali H. Sayed

Cognitive radio (CR) has recently emerged as a promising technology to revolutionize spectrum utilization in wireless communications. In a CR network, secondary users continuously sense the spectral environment and adapt transmission parameters to opportun ...

A Tabletop Learning Environment for Logistics Assistants: Activating Teachers

Pierre Dillenbourg, Patrick Jermann, Guillaume Zufferey

We describe a tabletop environment used in vocational schools to teach theoretical concepts to apprentices in lo gistics through the use of a small-scale model of a ware house. It provides a Tangible User Interface in the form of wooden shelves, metallic p ...
