Performance Evaluation of an IEEE 802.15.4a Physical Layer with Energy Detection and Multi-User Interference

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

We evaluate the performance of an IEEE 802.15.4a ultra-wide band (UWB) physical layer, with an energy-detection receiver, in the presence of multi-user interference (MUI). A complete packet based system is considered. We take into account packet detection ...

Hierarchical and Parallel Processing of Modulation Spectrum for ASR applications

Hynek Hermansky, Fabio Valente

The modulation spectrum is an efficient representation for describing dynamic information in signals. In this work we investigate how to exploit different elements of the modulation spectrum for extraction of information in automatic recognition of speech ...

Three topics in parallel communications

Emin Gabrielyan

The main objectives pursued by parallelism in communications are network capacity enhancement and fault-tolerance. Efficiently enhancing the capacity of a network by parallel communications is a non-trivial task. Some applications may also allow one to spl ...

A Novel Air-Gap Monitoring System For Large Low Speed Hydro-Generators.

Jean-Jacques Simond, Mai Tu Xuan, Roland Wetter, Stefan Keller

This paper describes a novel and patented air-gap monitoring system for large low speed synchronous hydro-generators. This new system is based on inductive sensors, it is able to measure in real time a static or a dynamic rotor eccentricity, a stator or a ...

Experimental and theoretical determination of low electron energy loss spectra of Ag and Ru

Cécile Hébert

We show the experimental and calculated q-dependent low energy loss electron energy loss spectrum of Ru and Ag. The spectra were calculated within the time-dependent density-functional theory including local-field effects. For Ag, the momentum transfer was ...

Reliable multi-path routing schemes for real-time streaming

Roger Hersch, Emin Gabrielyan

In off-line streaming, packet level erasure resilient forward error correction (FEC) codes rely on the unrestricted buffering time at the receiver. In real-time streaming, the extremely short playback buffering time makes FEC inefficient for protecting a s ...

Collaborating Hearing Aids

Martin Vetterli, Olivier Roy

Hearing aids are electronic, battery-operated sensing devices which aim at compensating various kinds of hearing impairments by means of appropriate signal processing. Most of today's hearing aid systems consist of two appliances working independently of e ...

Fault-tolerant parallel applications with dynamic parallel schedules

Roger Hersch, Sebastian Gerlach

Commodity computer clusters are often composed of hundreds of computing nodes. These generally off-the-shelf systems are not designed for high reliability. Node failures therefore drive the MTBF of such clusters to unacceptable levels. The software framewo ...

Three-dimensional anisotropic pressure equilibria that model balanced tangential neutral beam injection effects

Wilfred Anthony Cooper

Fixed boundary three-dimensional anisotropic pressure equilibria are computed that are consistent with a family of distribution functions that load particles preferentially towards v parallel to similar or equal to v and model the effects of balanced tange ...

Bandwidth-Constrained Mapping of Cores onto NoC Architectures

Giovanni De Micheli, Srinivasan Murali

We address the design of complex monolithic systems, where processing cores generate and consume a varying and large amount of data, thus bringing the communication links to the edge of congestion. Typical applications are in the area of multi-media proces ...
