Four-dimensional drift-kinetic model for scrape-off layer plasmas

Paolo Ricci, Rogério Manuel Cabete De Jesus Jorge

A four-dimensional plasma model able to describe the scrape-off layer region of tokamak devices at arbitrary collisionality is derived in the drift-reduced limit. The basis of the model is provided by a drift-kinetic equation that retains the full nonlinea ...

A hybrid control strategy for force and precise end effector positioning of a twisted string actuator

Jamie Paik, Andres San Millan Rodriguez

We propose a new control approach for the twisted string actuation (TSA) system; a hybrid control scheme consisting of two nested loops, considering the motor angle and the axial force at the clamping point of the actuator as the system outputs. We show th ...

Effect of task conditions on human hand pose selection strategies in bimanual fine manipulation tasks

Many manipulations in human everyday activities rely on the collaboration of our two hands. Bimanual fine manipulation tasks are particularly demanding as precise coordination among fingers of both hands is required. Yet, despite the abundant degrees of fr ...

Current Control Strategy for Dynamic Winding Reconfiguration of Slotless Brushless DC Motors

Yves Perriard, Douglas Martins Araujo, Florian Louis Copt

Depending on the winding configuration, the intrinsic characteristic of a motor differs. By reconfiguring the winding, it becomes possible to increase the torque–speed limitation of a motor. Current proposed methodologies for dynamically reconfiguring the ...

A comparative study of mode I delamination behavior of unidirectional glass fiber-reinforced polymers with epoxy and polyurethane matrices using two methods

John Botsis, Georgios Pappas

The mode I delamination behavior of a unidirectional glass-fiber reinforced polymer with a prototype elasto-plastic polyurethane matrix (GF/PU) was investigated and compared with that of glass/epoxy (GF/EP) using double cantilever beam specimens. Fracture ...

Leap-frog transport of magnetically driven anisotropic colloidal rotors

Ignacio Pagonabarraga Mora

In this article, we combine experiments and theory to investigate the transport properties of anisotropic hematite colloidal rotors that dynam ically assemble into translating clusters upon application of a rotating magnetic field. The applied field exerts ...

Development of a New Embedded Dynamometer for the Measurement of Forces and Torques at the Ski-Binding Interface

Alain Schorderet, Alain Michel Prenleloup, Frédéric Meyer

In alpine skiing, understanding the interaction between skiers and snow is of primary importance for both injury prevention as well as performance analysis. Risk of injuries is directly linked to constraints undergone by the skier. A force platform placed ...

Very-High-Speed Miniaturized Permanent Magnet Motors: Design and Optimization

Yves Perriard, Guillaume Paul-André Burnand

This paper aims to present an optimization method for very-high-speed electrical machines based on multiphysical analytical models. Analytical models allow a fast design but have to be robust and reliable. The set of models presented is very complete and c ...
