A robust, user-friendly, and automated method to determine quantum conductance in quasi-one-dimensional systems is presented. The scheme relies upon an initial density-functional theory calculation in a specific geometry after which the ground-state eigenf ...
Here Bernard Cache provides a detailed analysis of a paper written in 1636 by the French mathematician, architect and engineer, Girard Desargues. Desargues is best known as the founder of projective geometry. Cache explains how he initally developed this s ...
A drawing of a graph is x-monotone if every edge intersects every vertical line at most once and every vertical line contains at most one vertex. Pach and Toth showed that if a graph has an x-monotone drawing in which every pair of edges crosses an even nu ...
The influence of the geometry, via the ratio L/W of the Hall cells and the geometrical correction factor G on several figures of merit regarding Hall sensors is analyzed, namely the sensitivity, Hall Voltage and power dissipated within the device. Experime ...
This critical review discusses the current understanding of the formation, transport, and merging of drops in microfluidics. We focus on the physical ingredients which determine the flow of drops in microchannels and recall classical results of fluid dynam ...
In order to better identify the role of the magnetic topology on ITG and TEM instabilities, different MHD equilibria with increasing complexity are calculated using the CHEASE code [1]. We start from the geometry of the s-alpha cyclone benchmark case [2], ...
Voids and He bubbles are strong obstacles to dislocation, which induce hardening and loss of ductility. In Fe, molecular dynamics simulation is used to investigate the basic mechanisms of the interaction between a moving edge dislocation and a void or He b ...
This study deals with localization and characterization of multiple sources by mean of an octahedral array processing. We show how correlations enable to both localize more sources that the number of sensors and estimate their sound level pressure simultan ...
New EU and US emissions regulations require the development of advanced after- treatment systems for non-road diesel engine exhausts. To help develop these at Liebherr Machines Bulle, the use of CFD has been adopted. The pro ject used two main models: one ...
Many alpine torrents convey regularly debris flows of high destructive hazard. After several granular events observed in Bruchji?s torrent near the Blatten village in the Swiss Alps, it was decided to manage the risk of similar debris flows by designing an ...
