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 Decentralized Recommender System for Effective Web Credibility Assessment

Karl Aberer, Alexandra Olteanu, Jean-Eudes Marie Ranvier

An overwhelming and growing amount of data is available online. The problem of untrustworthy online information is augmented by its high economic potential and its dynamic nature, e.g. transient domain names, dynamic content, etc. In this paper, we address ...

A speckle-based CMOS sensor for arbitrary surface movement detection with correlated double sampling and gain error correction

Pierre-André Farine, Chao Wang, Steve Tanner

We present a CMOS sensor for accurate tracking of speckle movements on arbitrary surfaces. The sensor is made of a pair of comb filters with a pitch of 5.6 mu m and decayed by 90 degrees to produce quadrature signals. The readout circuit is a 60 dB amplifi ...

System design of a 24 GHz phased-array front-end for low-power applications

Pierre-André Farine, Cyril Botteron, Gabriele Tasselli, Ban Wang

This paper deals with the design of a 4-channel phased-array receiver Front-End (FE) architecture working at 24 GHz. Targeting low power applications such as radar sensors and medium bit-rate transceivers, a local oscillator shifting architecture is propos ...

Review of design aspects for high current Nb3Sn conductors

Pierluigi Bruzzone

Cabled conductors based on Nb3Sn technology with operating current in the range of 20 kA and above are mainly restricted to fusion magnets and high field facilities. The experience of last decade has dramatically shown that, opposite to the NbTi conductors ...

Geodesic Patterns

Bailin Deng

Geodesic curves in surfaces are not only minimizers of distance, but they are also the curves of zero geodesic (sideways) curvature. It turns out that this property makes patterns of geodesics the basic geometric entity when dealing with the cladding of a ...

Understanding the Web

Eda Baykan

The World Wide Web is one of the most widely used information resources. Understanding the web better will enable us to benefit more of it. In this thesis we develop techniques to learn the properties of the web pages like language and topic using only the ...

Integrated design of a gas separation system for the upgrade of crude SNG with membranes

Martin Gassner

This paper investigates different design strategies and process layouts for upgrading crude synthetic natural gas (SNG) produced from lignocellulosic biomass to grid quality. The design problem is outlined by studying the involved key aspects with respect ...

Ink thickness variations for the control of color printers

Roger Hersch, Peter Amrhyn

The present invention proposes a method and a computing system for deducing ink thickness variations from spectral reflectance measurements performed on a printing press or on a printer. The computed ink thickness variations enable controlling the ink depo ...

Methodology for the Design of Man-Portable Power Generation Devices

Benoît Chachuat

An overview of a comprehensive methodology for the design of microfabricated fuel cell systems for portable power generation is presented. The methodology is based on a decomposition into three levels of modeling detail: (i) system-level models for process ...

Color images visible under UV light

Roger Hersch, Sylvain Chosson, Philipp Donzé

The present contribution aims at creating color images printed with fluorescent inks that are only visible under UV light. The considered fluorescent inks absorb light in the UV wavelength range and reemit part of it in the visible wavelength range. In con ...
