Lagrange Equations Coupled to a Thermal Equation: Mechanics as Consequence of Thermodynamics

Following the analytic approach to thermodynamics developed by Stuckelberg, we study the evolution equations of a closed thermodynamic system consisting of point particles in a fluid. We obtain a system of coupled differential equations describing the mech ...

Surface second harmonic generation from coumarin 343 dye-attached TiO2 nanoparticles at liquid-liquid interface

Hubert Girault

The nonlinear optical properties of coumarin 343 (C343) dye-attached TiO2 nanoparticles in the size range 5-8 nm adsorbed at the interface of water/1,2-dichloroethane have been studied by using the surface second harmonic generation technique. No second ha ...

State-selective detection of velocity-filtered ND3 molecules

Andreas Osterwalder, Benjamin Bertsche

Translationally cold and slow ND3 is prepared by filtering the slow molecules from a thermal gas-phase sample using a curved electrostatic hexapole guide. This filter, like the curved quadrupole guide introduced by Rangwala et al. Phys. Rev. A 67 043406 (2 ...

Simulation numérique de phénomènes MHD

Gilles Steiner

The purpose of this thesis is the study, from the numerical simulation point of view, of the aluminum electrolysis process. Navier-Stokes equations for the computation of a two fluids flow with free interface are coupled with Maxwell equations describing t ...

Exact reconstruction with directional wavelets on the sphere

Pierre Vandergheynst, Yves Wiaux, Jason Douglas McEwen

A new formalism is derived for the analysis and exact reconstruction of band-limited signals on the sphere with directional wavelets. It represents an evolution of a previously developed wavelet formalism developed by Antoine & Vandergheynst and Wiaux et a ...

Analytical Solution for Rotor Eddy-Current Losses in a Slotless Permanent-Magnet Motor: The Case of Current Sheet Excitation

Yves Perriard, Miroslav Markovic

We present an analytical solution for the magnetic field, induced eddy currents, and the corresponding losses generated in the rotor of a slotless permanent-magnet (PM) motor. The field excitation is a current sheet placed at the stator interior surface. T ...

Double trouble

Jean-Jacques Simond, André Hodder, Alexander Schwery

This article presents the modeling, simulation, and practical application of a double-fed asynchronous motor-generator for pumped-storage plants equipped with a three-level VSI cascade. The problem of DC unbalance control is studied in this particular appl ...

Motion of a colloidal particle in an optical trap

László Forró, Andrzej Kulik, Sylvia Jeney, Branimir Lukic

Thermal position fluctuations of a colloidal particle in an optical trap are measured with microsecond resolution using back-focal-plane interferometry. The mean-square displacement MSD(t) and power spectral density are in excellent agreement with the theo ...

Binaural localization and separation techniques

Harald Viste

Abstract Based on binaural signals, i.e. the signals observed at the two ears, a listener can localize and recognize different sound sources and then focus on one of these. For decades, researchers have tried to invent a machine that can do the same under ...

A New Single-Phase Multilevel Modulator - A Fast and Accurate Method to Compute the Modulator Harmonic Spectra

Alfred Rufer

In the first part, a fast and accurate method to compute the harmonic spectra of PWM modulators is presented. This method allows to compute all measurements based on the harmonics values such as the THD or FWTHD. It is especially advantageous for multileve ...
