Generation of high-quality signals for optical sensing using DFB lasers injection locking

Injection locking of two DFB semiconductors opens new possibilities to generate effective signals for optical sensing, in order to reach better performances. Pure waveforms can be generated with qualities exceeding those obtained using external modulators. ...

Optimal control of an induction heating process for thixoforming

Jacques Rappaz, Alexandre Masserey

We investigate in this paper a numerical method to control the temperature of an induction heating process through electric current parameters such as frequency and current voltage imposed to the terminals of the inductor. We seek a sinusoidal voltage func ...

Mean-square performance of adaptive filters using averaging theory

Ali H. Sayed

This paper uses averaging analysis to study the mean-square performance of adaptive filters, not only in terms of stability conditions but also in terms of expressions for the mean-square error and the mean-square deviation of the filters, as well as in te ...

Mean-Square Performance of a Family of Affine Projection Algorithms

Ali H. Sayed

Affine projection algorithms are useful adaptive filters whose main purpose is to speed the convergence of LMS-type filters. Most analytical results on affine projection algorithms assume special regression models or Gaussian regression data. The available ...

Modeling the photoluminescence lifetime in realistic quantum wires

Benoît Marie Joseph Deveaud, Vincenzo Savona, Andrea Feltrin

We present a theoretical model of the time-resolved excitonic photoluminescence in quantum wires. We study the role of disorder and of the exciton-free-carrier interaction on the temperature dependence of the photoluminescence lifetime. We find that at low ...

On parallel computation of blood flow in human arterial network based on 1-D modelling

Alfio Quarteroni, Luca Formaggia

Parallel computation of blood flow in a 1D model of human arterial network has been carried out employing a Taylor Galerkin finite element method. Message passing interface libraries have been used on Origin 2000 SGI machine. A Greedy strategy for load-dis ...

Modelling the magnetic field effects in a high-Tc superconducting transformer

Francesco Grilli, Bertrand Dutoit

This paper describes quantitatively the magnetic field inside the windings of a HTS transformer. The results are obtained by means of finite element method simulations, using the electromagnetic software package Flux2D. The transformer design has been made ...

LWR-PROTEUS verification of reaction rate distributions in modern 10 10 boiling water reactor fuel

Rakesh Chawla, Fabian Jatuff

HELIOS, CASMO-4, and MCNP4B calculations of reaction rate distributions in a modern, fresh 10 10 boiling water reactor fuel element have been validated using the experimental results of the LWR-PROTEUS Phase I project corresponding to full-density water mo ...

Transient analysis of adaptive filters

Ali H. Sayed

This paper develops a framework for the mean-square analysis of adaptive filters with general data and error nonlinearities. The approach relies on energy conservation arguments and is carried out without restrictions on the probability distribution of the ...

Power laws for the spatial dependence of electrical parameters in the high-voltage capacitive RF sheath

Christoph Hollenstein, Alan Howling

Following the analytical description of the collisionless high-voltage capacitive RF sheath in Lieberman (1988) and of the collisional high-voltage capacitive RF sheath in Lieberman (1989), electrical sheath parameters are calculated for a square-wave ie R ...
