Integration of TDOA Features in Information Bottleneck Framework for Fast Speaker Diarization

Hervé Bourlard, Fabio Valente, Deepu Vijayasenan

In this paper we address the combination of multiple feature streams in a fast speaker diarization system for meeting recordings. Whenever Multiple Distant Microphones (MDM) are used, it is possible to estimate the Time Delay of Arrival (TDOA) for differen ...

Delay and coding in multiple-user communications

Stéphane Musy

In multiple-user communications, the bursty nature of the packet arrival times cannot be divorced from the analysis of the transmission process. However, in traditional information theory the random arrival times are smoothed out by appropriated source cod ...

Timing-Error-Tolerant Network-on-Chip Design Methodology

Giovanni De Micheli, Luca Benini, Srinivasan Murali, Federico Angiolini

With technology scaling, the wire delay as a fraction of the total delay is increasing, and the communication architecture is becoming a major bottleneck for system performance in systems on chip (SoCs). A communication-centric design paradigm, networks on ...

Isotopically selective collisional vibrational energy transfer in CF3H

Thomas Rizzo

We investigate here the mechanism of collisionally-enhanced isotopic selectivity observed in infrared multiple photon dissociation (IRMPD) of vibrationally pre-excited CF3H by Boyarkin et al. (J. Chem. Phys. 118, 93 (2003)). For both the carbon-12 and carb ...

Lucky Read/Write Access to Robust Atomic Storage

Rachid Guerraoui, Marko Vukolic, Ron Levy

This paper establishes tight bounds on the \emph{best-case} time-complexity of distributed atomic read/write storage implementations that tolerate \emph{worst-case} conditions. We study asynchronous robust implementations where a writer and a set of reader ...

Insights into excited-state and isomerization dynamics of bacteriorhodopsin from ultrafast transient UV absorption

Majed Chergui, Frank van Mourik, Selma Schenkl

A visible-pump/UV-probe transient absorption is used to characterize the ultrafast dynamics of bacteriorhodopsin with 80-fs time resoln. We identify three spectral components in the 265- to 310-nm region, related to the all-trans retinal, tryptophan (Trp)- ...

Real-time interaction over the Internet

Christophe Salzmann

This dissertation studied real-time interaction over the Internet (RTI2) in the context of remote experimentation where there is typically a person at the client side interacting with physical equipments at the server side. Remote experimentations of mecha ...

On the Long-Run Behavior of Equation-Based Rate Control

Jean-Yves Le Boudec, Milan Vojnovic

AbstractWe consider unicast equation-based rate con-trol, where, at some points in time, a sender adjusts its rate to f(p,r), where p is an on-line estimate of the loss-event rate observed by this source, r of the average round-trip time, and f is a TCP th ...

This paper establishes tight bounds on the best-case time-complexity of distributed atomic read/write storage implementations that tolerate worst-case conditions. We study asynchronous robust implementations where a writer and a set of reader processes (cl ...

Estimating the Delay and Coloration Effect of the Acoustic Echo Path for Low Complexity Echo Suppression

Christof Faller, Christophe Tournery

Acoustic echoes arise whenever there is acoustic coupling between a loudspeaker and a microphone. A traditional solution for eliminating the undesired echo signal is an acoustic echo canceler (AEC), which identifies the echo path between a loudspeaker and ...
