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.

Drones InSecurity

This project is about testing the security of casual/commercial drones. For this, we tested drones from the company Parrot, but the conclusions apply to all drones based on WiFi controllers. To test drones security, the project was divided in two parts. Th ...

Supply equipment to the new NBH system for the TCV tokamak

Alexander Karpushov, Damien Fasel, Ugo Siravo, Jérémie Dubray, Albert Perez

The TCV tokamak is equipped with a high power real time-controllable Electron Cyclotron Heating (ECH) system, made of 9 gyrotrons capable of 500 kW RF power. One of the major scientific challenge, the TCV upgrades aimed to, will be the access to a wider ra ...

Secure and Private Proofs for Location-Based Activity Summaries in Urban Areas

Jean-Pierre Hubaux, Kévin Clément Huguenin, Igor Bilogrevic, Thi Van Anh Pham

Activity-based social networks, where people upload and share information about their location-based activities (e.g., the routes of their activities), are increasingly popular. Such systems, however, raise privacy and security issues: the service provider ...

Wireless Network Simplification: The Gaussian N-Relay Diamond Network

Christina Fragouli

We consider the Gaussian N-relay diamond network, where a source wants to communicate to destination node through a layer of N-relay nodes. We investigate the following question: what fraction of the capacity can we maintain using only k out of the N avail ...

Institute of Electrical and Electronics Engineers2014

In many cases, we can only have access to a service by proving we are sufficiently close to a particular location (e.g. in automobile or building access control). In these cases, proximity can be guaranteed through signal attenuation. However, by using add ...

, ,

Intra-session network coding has been shown to offer significant gains in terms of achievable throughput and delay in settings where one source multicasts data to several clients. In this paper, we consider a more general scenario where multiple sources tr ...

Maximum Throughput Gain of Compute-and-Forward for Multiple Unicast

Michael Christoph Gastpar, Jasper Goseling

Compute-and-Forward (CF), also known as reliable physical layer network coding, is a technique that provides the possibility of exploiting the features of broadcast and superposition in wireless networks. It has been shown that the throughput for multiple ...

Institute of Electrical and Electronics Engineers2014

This book chapter describes Raman Based Distributed Optical Fiber Sensors and their main industrial applications. In particular, after a brief introduction on the basic physical mechanisms, and a theoretical description of distributed optical fiber sensors ...

Gravity Gradient Earth Sensor experiment on REXUS 11

Herbert Shea, Simon Dandavino, Muriel Richard, Kaustav Ghose, Daniel Mueller, Hervé Meyer, Benoît Chamot, Jean-Noël Pittet, Yann Voumard, Jean-François Labrecque-Piedboeuf

This experiment is the first test of the concept for a novel attitude determination sensor in freefall, that utilizes the Earth`s gravity gradient as a reference. Current sensors require multiple optical heads with access on all faces of a satellite that m ...
