KSm(MoO4)2, an incommensurately modulated and partially disordered scheelite-like structure

Gervais Chapuis, Alla Arakcheeva, Philip Pattison

The incommensurately modulated scheelite-like KSm(MoO4)2 structure has been refined in the monoclinic superspace group I2/b(ab0)00 by the Rietveld method on the basis of synchrotron radiation powder diffraction data. The systematic broadening of satellite ...

A Generalized Sampling Method for Finite-Rate-of-Innovation-Signal Reconstruction

Michaël Unser, Chandra Sekhar Seelamantula

The problem of sampling signals that are not admisible within the classical Shannon framework has received much attention in the recent past. Typically, these signals have a parametric representation with a finite number of degrees of freedom per time unit ...

First measurements of oblique ECE with a real-time moveable line-of-sight on TCV

Olivier Sauter, Timothy Goodman, Christian Schlatter, Igor Klimanov

Electron cyclotron (EC) emission (ECE) radiometers viewing perpendicular to the magnetic field are common on nearly all tokamaks for measuring the electron temperature with good spatio-temporal resolution. Two such radiometers are installed on TCV, one loo ...

Characterization of equilibrium measures for critical reversible Nearest Particle Systems

We show that for critical reversible attractive Nearest Particle Systems all equilibrium measures are convex combinations of the upper invariant equilibrium measure and the point mass at all zeros, provided the underlying renewal sequence possesses moments ...

HandCARE: a cable-actuated rehabilitation system to train hand function after stroke

Thomas Maeder, Roger Gassert, Etienne Burdet, Olivier Lambercy, Ludovic Dovat

Abstract—We have developed a robotic interface to train hand and ﬁnger function. HandCARE is a Cable-Actuated REhabilitation system, in which each ﬁnger is attached to an instrumented cable loop allowing force control and a predominantly linear displacemen ...

Estimating Spectral Information of Complex Fenestration Systems in a Video-Goniophotometer

Marilyne Andersen

The effective use of complex fenestration systems in buildings requires knowledge of their optical spectral and directional properties. While the directional properties are commonly assessed by the measurement of bidirectional transmission or reflection di ...

New Methods for Assessing Spectral, Bi-directional Transmission and Reflection by Complex Fenestration Systems

Marilyne Andersen

Advanced fenestration systems are increasingly being used to distribute solar radiation purposefully in buildings. Distribution of visible light and near infrared radiation can be optimized for daylighting and to reduce thermal loads. This can be achieved ...

On the definition of a kinetic equilibrium in global gyrokinetic simulations

Olivier Sauter, Laurent Villard, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Paolo Angelino

Nonlinear electrostatic global gyrokinetic simulations of collisionless ion temperature gradient (ITG) turbulence and ExB zonal flows in axisymmetric toroidal plasmas are examined for different choices of the initial distribution function. Using a local Ma ...

Winding strings in AdS3

Correlation functions of one-unit spectral flowed states in string theory on AdS3 are considered. We present the modified Knizhnik-Zamolodchikov and null vector equations to be satisfied by amplitudes containing states in winding sector one and study their ...

Validation of the performance of a new bidirectional video-goniophotometer

Marilyne Andersen

An accurate knowledge of the directional optical properties of advanced fenestration materials is necessary for them to be adequately integrated in buildings. These properties are expressed by the Bidirectional Transmission (or Reflection) Distribution Fun ...
