Parametric Resonance in Time-Dependent Networks of Hopf Oscillators

We study a collection of limit cycle oscillators with different frequencies interacting via networks. With static networks, our specific class of models produces a frequency learning mechanism leading the collection of oscillators to ultimately adopt a sin ...

A 3D multi-mode geometry-independent RMP optimization method and its application to TCV

Yves Martin, Jean-Marc Moret, Jonathan Rossel

Resonant magnetic perturbation (RMP) and error field correction (EFC) produced by toroidally and poloidally distributed coil systems can be optimized if each coil is powered with an independent power supply. A 3D multi-mode geometry-independent Lagrange me ...

GUI-Aided NIR and Color Image Blending

Sabine Süsstrunk, Radhakrishna Achanta, Andrea Guidi

A near-infrared (NIR) image of a scene contains different information than the corresponding visible spectrum (RGB) image, due to physical phenomena related to scattering, absorption, and reflectance of the different radiation bands. It can be desirable to ...

Emission characteristics of GaN-based blue lasers including a lattice matched Al0.83In0.17N optical blocking layer for improved optical beam quality

Nicolas Grandjean, Jean-François Carlin, Eric Feltin, Julien Dorsaz, Antonino Francesco Castiglia, Gatien Cosendey

We demonstrate room-temperature continuous-wave operation of 425 nm InGaN-based blue laser diodes including a thin Al0.83In0.17N optical blocking layer. Structures are grown on c-plane GaN freestanding substrates with a lattice-matched AlInN layer position ...

An evaluation of the estimation of road traffic emission factors from tracer studies

Alain Clappier, Luis Carlos Belalcazar Ceron

Road traffic emission factors (EFs) are one of the main sources of uncertainties in emission inventories; it is necessary to develop methods to reduce these uncertainties to manage air quality more efficiently. Recently an alternative method has been propo ...

Microwave absorption in the frustrated ferrimagnet Cu2OSeO3

Helmuth Berger

The resonance properties of a new Cu2OSeO3 ferrimagnet have been investigated in a wide range of frequencies (17-142 GHz) at liquid helium temperature. The resonance data were used to plot the frequency-field curve of the ferromagnetic spectrum described i ...

Characterization of photoelectrochemical cells for water splitting by electrochemical impedance spectroscopy

The photocurrent-voltage characteristic of a photoelectrochemical cell for solar hydrogen production via water splitting, using undoped-hematite as photoanode, was obtained. Photoelectrochemical characteristics of the cell were also investigated by electro ...

A modulated gradient model for large-eddy simulation: Application to a neutral atmospheric boundary layer

Fernando Porté Agel

The subgrid-scale (SGS) parametrization represents a critical component of a successful large-eddy simulation (LES). It is known that in LES of high-Reynolds-number atmospheric boundary layer turbulence, standard eddy-viscosity models poorly predict mean s ...
