"Can you hear me now?"
This thesis deals with signal-based methods that predict how listeners perceive speech quality in telecommunications. Such tools, called objective quality measures, are of great interest in the telecommunications industry to evaluate how new or deployed sy ...
EPFL2016Discovering places of interest in everyday life from smartphone data
In this paper, a new framework to discover places-of-interest from multimodal mobile phone data is presented. Mobile phones have been used as sensors to obtain location information from users’ real lives. A place-of-interest is defined as a location where ...
Springer2013QoSNC: A Novel Approach to QoS-Based Network Coding for Fixed Networks
In this paper, we present a decentralized algorithm to find minimum cost quality of service (QoS) flow subgraphs in network coded multicast schemes. The main objective is to find minimum cost subgraphs that also satisfy user-specified QoS constraints, spec ...
2010Discovering Human Places of Interest from Multimodal Mobile Phone Data
In this paper, a new framework to discover places-of-interest from multimodal mobile phone data is presented. Mobile phones have been used as sensors to obtain location information from users’ real lives. Two levels of clustering are used to obtain place ...
2010End-to-end adaptation scheme for ubiquitous remote experimentation
Denis Gillet, Christophe Salzmann, Philippe Müllhaupt
Remote experimentation is an effective e-learning paradigm for supporting hands-on education using laboratory equipment at distance. The current trend is to enable remote experimentation in mobile and ubiquitous learning. In such a context, the remote expe ...
2009Efficient Broadcasting Using Network Coding
Jean-Yves Le Boudec, Christina Fragouli, Jörg Widmer
We consider the problem of broadcasting in an ad-hoc wireless network, where all nodes of the network are sources that want to transmit information to all other nodes. Our figure of merit is energy efficiency, a critical design parameter for wireless netwo ...
2008Industry boundaries in times of change: how do firms strategize?
Matthias Finger, Jeannine Srivastava
We are interested in markets which are being restructured or about to be created, as a result of the co-evolution of technologies and market dynamics. A systemic analysis of competition alternatives among groups of firms seems more accurate in order to und ...
2005Joint source-channel coding with feedback
Communications is about conveying information from one point to another subject to certain performance constraints. The information is assumed to be generated by a source and may, for example, represent a voice waveform, the reading of a thermal sensor, or ...
EPFL2005Aural and automatic forensic speaker recognition in mismatched conditions
Andrzej Drygajlo, Anil Alexander
In this article, we compare aural and automatic speaker recognition in the context of forensic analyses, using a Bayesian framework for the interpretation of evidence. We use perceptual tests performed by non-experts and compare their performance with that ...
2005Controlled multimedia wireless link sharing via enhanced class-based queuing with channel-state-dependent packet scheduling
A key problem in transporting multimedia traffic across wireless networks is a controlled sharing of the wireless link by different packet streams. So far this problem has been treated as that of providing support for quality of service in time division mu ...
