Performance analysis of dual-hop fixed-gain AF relaying systems with OSTBC over Nakagami-m fading channels

In this paper, we present outage probability and symbol error rate (SER) performance analyses of a dual-hop transmission using fixed-gain amplify-and-forward relaying in flat Nakagami-m fading channels. The system under consideration is equipped with multi ...

Statistical analysis of oxides particles in ODS ferritic steel using advanced electron microscopy

Cécile Hébert, Nadine Baluc, Guillaume Lucas

In this work a combination of advanced transmission electron microscopy and spectroscopy techniques enabled a statistically significant analysis of various types of few nanometer size oxides particles in Fe-14Cr-2W-O.3Ti-0.3Y(2)O(3) ferritic steel. These m ...

Signal fluctuations in fMRI data acquired with 2D-EPI and 3D-EPI at 7 Tesla

Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, João Pedro Forjaco Jorge, Patricia Figueiredo

Segmented three-dimensional echo planar imaging (3D-EPI) provides higher image signal-to-noise ratio (SNR) than standard single-shot two-dimensional echo planar imaging (2D-EPI), but is more sensitive to physiological noise. The aim of this study was to co ...

Deterministic characterization of phase noise in biomolecular oscillators

Marc Hafner

On top of the many external perturbations, cellular oscillators also face intrinsic perturbations due the randomness of chemical kinetics. Biomolecular oscillators, distinct in their parameter sets or distinct in their architecture, show different resilien ...

Cepstral normalisation and the signal to noise ratio spectrum in automatic speech recognition.

Philip Neil Garner

Cepstral normalisation in automatic speech recognition is investigated in the context of robustness to additive noise. It is argued that such normalisation leads naturally to a speech feature based on signal to noise ratio rather than absolute energy (or p ...

Workshop: Next-Generation Fibers for High Capacity Transmission—Radical Solutions

Hans Georg Limberger

Driven by the exponentially growing demand for capacity, it is already apparent that the next generation of telecommunication networks will be radically different from previous implementations; coherent detection along with powerful digital signal processi ...

Direct Piezoresistive Simulation Tool

Nico de Rooij, Terunobu Akiyama, Sebastian Gautsch, Peter Vettiger, Frédéric Loizeau

Biosensors often require detecting infinitesimal amount of species, thus their readout must be improved for highest sensitivity and best Signal-to-Noise ratio. We will present a simulation tool for piezoresistive strain sensors, which takes into account no ...

An Implantable System for Angle Measurement in Prosthetic Knee

Kamiar Aminian, Arash Arami, Hooman Dejnabadi

In this work we designed and tested an in-vivo measurement system of prosthetic knee joint angles. The system included a small permanent magnet in the femoral part and three magneto resistance sensors placed in the polyethylene part. The sensor configurati ...

Enhancing Single Molecule Imaging in Optofluidics and Microfluidics

Andreas Vasdekis, Grégoire Pierre Jean Laporte

Microfluidics and optofluidics have revolutionized high-throughput analysis and chemical synthesis over the past decade. Single molecule imaging has witnessed similar growth, due to its capacity to reveal heterogeneities at high spatial and temporal resolu ...
