Spectral validation of rank deficient kinetic models

Julien Léo Billeter, Konrad Hungerbühler

Kinetic hard-modelling is often the method of choice in order to determine kinetic parameters of reactions by non-linear optimisation and fitting of measured data. In spectroscopy, kinetic hard-modelling allows decomposing time and wavelength resolved data ...

Compute-and-Forward: A Novel Strategy for Cooperative Networks

Michael Christoph Gastpar

In recent work, we have shown that in a Gaussian network, nodes can often recover linear combinations of transmitted codewords much more efficiently than the codewords themselves. These nodes, after decoding their linear equations, simply send them towards ...

Compute-and-Forward: Harnessing Interference with Structured Codes

Michael Christoph Gastpar

For a centralized encoder and decoder, a channel matrix is simply a set of linear equations that can be transformed into parallel channels. We develop a similar approach to multiuser networks: we view interference as creating linear equations of codewords ...

A new definition of threshold voltage in Tunnel FETs

Mihai Adrian Ionescu, Katherine Boucart

This work reports on the physical definition and extraction of threshold voltage in Tunnel FETs (field effect transistors) based on numerical simulation data. It is shown that the Tunnel FET has the outstanding property of having two threshold voltages: on ...

Amorphous hafnium silicates: structural, electronic and dielectric properties

Alfredo Pasquarello, Peter Broqvist

Models of amorphous (HfO2)x(SiO2)(1), for varying hafnium, content x are generated by ab initio molecular dynamics. The structural properties are analyzed in terms of pair distribution functions from which typical bond lengths and coordination numbers are ...

Second-order hyperbolic S.P.D.E.'s driven by homogeneous Gaussian noise on a hyperplane

Robert Dalang, Olivier Lévêque

We study a class of hyperbolic stochastic partial di®erential equations in Euclidean space, that includes the wave equation and the telegraph equation, driven by Gaussian noise concentrated on a hyperplane. The noise is assumed to be white in time but spat ...

Inelastic Strain Birefringence in Optical Fibers

René Salathé, Hans Georg Limberger, Florian Dürr

Retardation data captured by polarimetric stress-measurements in optical fibers have been reinterpreted in terms of both stress and inelastic strain. The linear dependence of strain birefringence on fiber drawing tension defines the Kohlrausch-Williams-Wat ...

Analysis of the Swirling Flow Downstream a Francis Turbine Runner

François Avellan

An experimental and theoretical investigation of the flow at the outlet of a Francis turbine runner is carried out in order to elucidate the causes of a sudden drop in the draft tube pressure recovery coefficient at a discharge near the best efficiency ope ...

Nodal DG-FEM solution of high-order Boussinesq-type equations

Jan Sickmann Hesthaven

A discontinuous Galerkin finite-element method (DG-FEM) solution to a set of high-order Boussinesq-type equations for modelling highly nonlinear and dispersive water waves in one horizontal dimension is presented. The continuous equations are discretized u ...
