Motor-wheel for an omni-directional mechanism and vehicle using the same

Mohsen Falahi

The present invention relates to a motor-wheel for an omni-directional motion vehicle, comprising a ring-shaped structure with a central axis, presenting an outer radial surface and an inner radial surface, whereby the outer radial surface comprises a plur ...

The viscous torsional pendulum

François Gallaire, Francesco Viola

A disk that is free to rotate about its axis and connected to a torsional spring behaves as a damped oscillator when twisted and released. The initial elastic energy is periodically turned to kinetic energy and it gets progressively dissipated by the visco ...

Estimation of transverse spin penetration length using second-harmonic measurement: Proposal of an experimental method

Jean-Philippe Ansermet

A theoretical description of spin current injection from a nonmagnetic layer into a magnetic one is presented, with the main emphasis on the description and determination of the penetration depth of spin current component transverse to the magnetization. T ...

Lower hybrid current drive experiments with different launched wave frequencies in the EAST tokamak

Jian Wang, Joan Decker, Mingkui Wang, Fang Liu, Yong Yang

EAST has been equipped with two high power lower hybrid current drive (LHCD) systems with operating frequencies of 2.45 GHz and 4.6 GHz. Comparative LHCD experiments with the two different frequencies were performed in the same conditions of plasma for the ...

A mechanistic approach to topsoil damage due to slip of tractor tyres

Lyesse Laloui, Andrea Battiato, Etienne Diserens

Tractor traction tyres interact with soil by a system of normal and tangential stresses along the soil-tyre contact surface. In this interaction both soil and tyre deform according to their own stress-strain relationships. Soil deformation results in the f ...

Overview of experimental results and code validation activities at Alcator C-Mod

Christian Gabriel Theiler

Recent research on the Alcator C-Mod tokamak has focused on a range of scientific issues with particular emphasis on ITER needs and on detailed comparisons between experimental measurements and predictive models. Research on ICRF (ion cyclotron range of fr ...

A fully integrated Hall sensor microsystem with current-mode output

Maher Kayal, Marc Pastre, Andrea Ajbl

This paper presents a fully integrated Hall sensor microsystem with a current-mode output. The system operates in open-loop and includes a Hall sensor with internal biasing, a fully differential front-end, a preamplifier chain and a voltage-to-current conv ...

A four-motor drive supplied from a triple three-phase voltage source inverter

Drazen Dujic

Since control of a three-phase machine requires only two currents, it is possible to independently control a number of three-phase machines using reduced-switch-count voltage source inverter (VSI) topologies. One such configuration consists of n three-phas ...
