Effect of Model Accuracy on the Result of Computed Current Densities in the Simulation of Transcranical Magnetic Stimulation

Juan Ramon Mosig, Michael Mattes, Laleh Golestanirad

One of the most hindering limitations in the simulation of a realistic biological system is the complexity of the model which may easily lead to a very heavy computational burden. This may seriously question the possibility of optimizing system parameters ...

Very high-speed slotless permanent-magnet motors

Pierre-Daniel Pfister

The development of very high-speed motors has evolved fascinatingly in the last few years. Due to their speed, their low weight and their high power density, the need for such motors has recently increased for various different applications. Among them, su ...

Intermittency and blob dynamics in the TORPEX device

Ivo Furno

Intermittent convective transport caused by blobs is universally observed at the edge of laboratory plasmas and it is of great importance for future fusion reactors. We present recent advances in the basic study of blob formation and propagation dynamics a ...

Blob motion and control in simple magnetized plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Benoît Labit, Christian Gabriel Theiler, Nicola Vianello, Davoud Iraji

Intermittent convective transport caused by coherent structures, or blobs, are universally observed in the edge of laboratory plasmas. Besides being of fundamental physics interest, the dynamics of these structures in fusion reactors influence the density ...

A partition-free approach to transient and steady-state charge currents

We construct a non-equilibrium steady state and calculate the corresponding current for a mesoscopic Fermi system in the partition-free setting. To this end we study a small sample coupled to a finite number of semi-infinite leads. Initially, the whole sys ...

Finite Element Model of Hydro Generators Coupled to a Grid Simulation Software

Gilles Rosselet

For the simulation of electrical power systems (adjustable speed drives, wind farms, complete grids, etc.) the Kirchhoff's model is used. Each of the components of this model (transmission line, circuit breaker, electrical machines, etc.) is represented by ...

Evidence for Thermal Spin-Transfer Torque

Jean-Philippe Ansermet, Haiming Yu, Simon Granville

Large heat currents are obtained in Co/Cu/Co spin valves positioned at the middle of Cu nanowires. The second harmonic voltage response to an applied current is used to investigate the effect of the heat current on the switching of the spin valves. Both th ...

A Novel Multi-Working Electrode Potentiostat for Electrochemical Detection of Metabolites

Giovanni De Micheli, Sandro Carrara, Cristina Boero, Michele Daniel Torre, Daniela De Venuto

A novel single-chip and multiplexed read-out circuit for multi-electrode electrochemical sensors, in standard 0.18 μm UMC CMOS technology, is presented. The circuit is a part of a fully-integrated biochip (in design) for the detection of multiple metabolit ...
