VENUS-LEVIS and its spline-Fourier interpolation of 3D toroidal magnetic field representation for guiding-centre and full-orbit simulations of charged energetic particles

Jonathan Graves, Wilfred Anthony Cooper, David Pfefferlé, Cyril Misev

Curvilinear guiding-centre drift and full-orbit equations of motion are presented as implemented in the code{VENUS-LEVIS} code. A dedicated interpolation scheme based on Fourier reconstruction in the toroidal and poloidal direction and cubic spline in the ...

Quadrupedal locomotion using hierarchical operational space control

Roland Siegwart, Marco Hutter

This paper presents the application of operational space control based on hierarchical task optimization for quadrupedal locomotion. We show how the behavior of a complex robotic machine can be described by a simple set of least squares problems with diffe ...

Muscles in a Shoulder Model: Identification of the necessary number of muscle cables

Jeannette Liniger

The shoulder complex is a complex articulation of the human body. It consists of several bones and joints and is moved and stabilized by 16 muscles. The muscle forces can not be measured experimentally, but can be computed using numerical methods. An exist ...

BOLTZWANN: A code for the evaluation of thermoelectric and electronic transport properties with a maximally-localized Wannier functions basis

Nicola Marzari, Giovanni Pizzi, Boris Kozinsky

We present a new code to evaluate thermoelectric and electronic transport properties of extended systems with a maximally-localized Wannier function basis set. The semiclassical Boltzmann transport equations for the homogeneous infinite system are solved i ...

Threshold Saturation in Spatially Coupled Constraint Satisfaction Problems

Rüdiger Urbanke, Nicolas Macris, Seyed Hamed Hassani

We consider chains of random constraint satisfaction models that are spatially coupled across a finite window along the chain direction. We investigate their phase diagram at zero temperature using the survey propagation formalism and the interpolation met ...

On the coupling between an ideal fluid and immersed particles

Tudor Ratiu, Mathieu Desbrun

In this paper, we present finite-dimensional particle-based models for fluids which respect a number of geometric properties of the Euler equations of motion. Specifically, we use Lagrange-Poincare reduction to understand the coupling between a fluid and a ...

Thin film bulk acoustic wave resonators tuning from first principles

Alexander Tagantsev, Alexander Kvasov

Being important for the antiresonance frequency tuning of tunable thin Film Bulk Acoustic wave Resonators (FBARs), the non-linear electrostrictive coefficient was for the first time calculated for BaTiO3 and SrTiO3 using ab initio methods. Further, taking ...

Linear Interpolation Of Biomedical Images Using A Data-Adaptive Kernel

Michaël Unser, John Paul Ward, Aurélien Bourquard, Hagay Kirshner

In this work, we propose a continuous-domain stochastic model that can be applied to image data. This model is autoregressive, and accounts for Gaussian-type as well as for non-Gaussian-type innovations. In order to estimate the corresponding parameters fr ...

Influence of numerical schemes on statistical properties of computed charged particle trajectories in turbulent electromagnetic fields

A class of numerical schemes is developed for the study of charged particle transport in complex stationary electromagnetic fields and tested for fields obtained from a numerical solution of the magneto-hydrodynamic equation. The performances of these sche ...

A real-time multi-aperture omnidirectional visual sensor with interconnected network of smart cameras

Hossein Afshari

A novel omnidirectional visual sensor called the Panoptic camera is introduced. The Panoptic camera is an omnidirectional multi-aperture visual system which is realized by mounting multiple camera sensors on a hemispherical frame. The introduced visual sen ...
