Effects of central electron cyclotron power on plasma rotation and on triggerless onset of NTMs in the TCV tokamak

Olivier Sauter, Basil Duval, Duccio Testa, Holger Reimerdes, Alexander Karpushov, Doohyun Kim, Dávid Wágner, Lucia Isabel Federspiel, Jonathan Rossel, Donghyun Kim

Experiments on the TCV tokamak show that high power central electron cyclotron heating (ECH) and current drive (ECCD) produce significant direct modification of the plasma rotation profile, as well as the effect on the equilibrium current density. These ef ...

Modular medium voltage drive for demanding applications

Drazen Dujic

Nowadays, several state-of-the-art multilevel converter topologies are used for numerous industrial medium-voltage (MV) high-power variable-speed drive applications. The 3-level neutral point clamped (3L-NPC) topology is one of those and is often used as a ...

White matter integrity of premotor-motor connections is associated with motor output in chronic stroke patients

Friedhelm Christoph Hummel

Corticocortical functional interactions between the primary motor cortex (M1) and secondary motor areas, such as the dorsal (PMd) and ventral (PMv) premotor cortices and the supplementary motor area (SMA) are relevant for residual motor output after subcor ...

Muscle Spindle Feedback Directs Locomotor Recovery and Circuit Reorganization after Spinal Cord Injury

Grégoire Courtine, Isabel Laura Vollenweider

Spinal cord injuries alter motor function by disconnecting neural circuits above and below the lesion, rendering sensory inputs a primary source of direct external drive to neuronal networks caudal to the injury. Here, we studied mice lacking functional mu ...

Driver electronics for efficient low noise stepper motor operation

Stepper motors are a very convenient and economical solution for accurate positioning applications where long lifetime and low wear are required. Their particularly simple open-loop operation reduces the number of control components to a minimum. However, ...

Characterization of Surface Cracks Through The Local Magnetic Field Induced by Eddy Currents

Hannes Bleuler, Marco Picasso, Pavel Kejik, Roland Moser, Gilles Raphaël Santi, David Florian Hippert

It is important to reliably characterize cracks in metallic mechanical parts in order to assess the serenity of damage due to fatigue. The most important parameter for this is the crack depth. This is notoriously difficult with standard Eddy current techni ...

A dual-axis pointing mirror with moving-magnet actuation

Nico de Rooij, Caglar Ataman, Wilfried Noell, Sébastien Lani

A large-aperture and large-angle MEMS-based 2D pointing mirror is presented. The device is electromagnetically actuated by a moving-magnet/stationary-coil pair and potentially suited for high power laser beam shaping and beam pointing applications, such as ...

Decoding the mechanisms of gait generation in salamanders by combining neurobiology, modeling and robotics

Auke Ijspeert, Andrej Bicanski

Vertebrate animals exhibit impressive locomotor skills. These locomotor skills are due to the complex interactions between the environment, the musculo-skeletal system and the central nervous system, in particular the spinal locomotor circuits. We are inte ...
