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.

A Topological Treatment of Early-Deciding Set-Agreement

Rachid Guerraoui, Bastian Pochon

The k-set-agreement problem consists for a set of n processes to agree on less than k among n possibly different Values, each initially known to only one process. The problem is at the heart of distributed computing and generalizes the celebrated consensus ...

Structural identification to improve bridge management

Ian Smith, James-Alexandre Goulet

This paper presents results from static loads tests performed on the new Langensand Bridge built in Switzerland. A systematic study of over 1000 models subjected to three load cases identifies a set of 11 candidate models through static measurements. Predi ...

Clock-Offset Tracking Software Algorithms For IR-UWB Energy-Detection Receivers

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

We present a clock-offset tracking algorithm for impulse-radio ultra-wide band (IR-UWB) energy-detection receivers. There is a complexity versus performance trade-off for the design of IR-UWB energy-detection receivers: Extremely low-complexity energy-dete ...

Partial cognitive relay channel

Masih Nilchian, Vahid Aref

We define partial cognitive relay channel as a two-transmitter, two-receiver interference channel with a relay node such that one of the transmitters is a cognitive transmitter. As a more feasible assumption we assume that the cognitive transmitter has non ...

Real-time Carrier Generation for a GNSS Software Receiver

Pierre-André Farine, Cyril Botteron, Marcel Baracchi Frei

The growing market of GNSS capable mobile devices is driving the interest of software receiver solutions as they can share many resources with other system units, reducing both the size and the cost of their integration. However, a major issue with the sof ...

On Broadcast with a Common Message over Networks

Satish Babu Korada, Dinkar Vasudevan

We consider the following communication problem over a directed graph. A source node wants to transmit a common message to a set of receiver nodes along with a private message to each of the receivers. We show a class of networks for which the achievable r ...

Broadcast and Slepian-Wolf multicast over Aref Networks

Satish Babu Korada, Dinkar Vasudevan

We consider source coding over Aref networks. In particular we consider the following two problems: (i) multicasting correlated sources to a set of receivers, (ii) broadcasting sources to their respective receivers. For the first problem we show necessary ...

A low-power 2.4 GHz CMOS receiver using BAW resonators

Jérémie Chabloz

It has already been a few years since the first appearance of micro-electromechanical systems (MEMS) in academic research. Since then, a broad number of devices have been designed under this generic term. Bulk-acoustic wave (BAW) resonators are among the f ...

A frame-start detector for a 4 x 4 MIMO-OFDM system

Andreas Peter Burg

Future wireless LANs will increase the peak data rate by employing multiple antennas at both transmitter and receiver. ...

Towards Design Strategies to Deal with Spatial Uncertainty in Location-Aware Systems

Nicolas Nova

Building ubiquitous applications that exploit location requires both low-level underlying infrastructure for linking sensors and managing spatial information and also high-level representation of the measured space to produce a pleasant user experience. Ho ...
