Time-Dependent Searches For Point Sources Of Neutrinos With The 40-String And 22-String Configurations Of Icecube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

This paper presents four searches for flaring sources of neutrinos using the IceCube neutrino telescope. For the first time, a search is performed over the entire parameter space of energy, direction, and time with sensitivity to neutrino flares lasting be ...

Young firms and innovation: A microeconometric analysis

Gabriele Pellegrino

This paper discusses the sources of product innovation in young innovative companies (YICs), here defined as firms engaged in product innovation and with less than 8 years of activity. In particular, we look at in-house and external R&D and at the acquisit ...

Quantum Technology: Single-Photon Source

Vincent Frédéric Camus

This report is a synthesis of my master thesis internship at the National Institute of Informatics (NII) in Tokyo, Japan, that lasted during the summer of year 2012. I worked in the Quantum Information Science Theory (QIST) group under supervision of Prof. ...

Benefits and Scepticism of Ecolabels as Accountability Mechanism

Ralf Seifert, Joana Maria Comas Marti

Environmental labelling is an accountability mechanism for firms to satisfy growing demands to prove that value chains are sustainably managed. Although the large variety of ecolabels available today can be interpreted as a sign of their success, it is ove ...

Sensor Networks for Diffusion Fields: Detection of Sources in Space and Time

Martin Vetterli, Ivan Dokmanic, Juri Ranieri, Amina Chebira

Abstract—We consider the problem of reconstructing a diffusion field, such as temperature, from samples collected by a sensor network. Motivated by the fast decay of the eigenvalues of the diffusion equation, we approximate the field by a truncated series. ...

Semantic Sensor Data Search in a Large-Scale Federated Sensor Network

Karl Aberer, Jean Paul Calbimonte Perez, Ho Young Jeung

Sensor network deployments are a primary source of massive amounts of data about the real world that surrounds us, measuring a wide range of physical properties in real time. However, in large-scale deployments it becomes hard to eectively exploit the data ...

Universal Source Polarization and Spare Recovery

Emmanuel Abbé

Polar codes allow to perform lossless compression of i.i.d. sources at the lowest rate with low encoding and decoding complexity. In this paper, it is shown that for binary sources, there exist “universal polar codes” which can compress any source of low e ...

Emerging Risks: Sources, Drivers and Governance Issues (2nd ed.)

Marie-Valentine Renée Agnès Florin

With this concept note, IRGC intends to help improve the understanding and governance of emerging risks that have impacts on human health and safety, the environment, the economy and society at large. It draws from a roundtable discussion in 2009 about why ...

Study of an octahedral antenna for both sound pressure level estimation and 3D localization of multiple sources

Hervé Lissek, Xavier Falourd, Patrick Marmaroli

This study deals with localization and characterization of multiple sources by mean of an octahedral array processing. We show how correlations enable to both localize more sources that the number of sensors and estimate their sound level pressure simultan ...

Blind Audio-Visual Source Separation based on Sparse Redundant Representations

Pierre Vandergheynst, Rémi Gribonval, Gianluca Monaci, Anna Llagostera Casanovas

In this paper we propose a novel method which is able to detect and separate audio-visual sources present in a scene. Our method exploits the correlation between the video signal captured with a camera and a synchronously recorded one-microphone audio trac ...

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.
