Inductive Power Link for a Wireless Cortical Implant With Two-Body Packaging

Catherine Dehollain, Michel Declercq, Kanber Mithat Silay

This paper presents an inductive power link for remote powering of a wireless cortical implant. The link includes a Class-E power amplifier, a gate driver, an inductive link, and an integrated rectifier. The coils of the inductive link are designed and opt ...

Balancing current drive and heating in DIII-D high noninductive current fraction discharges through choice of the toroidal field

Holger Reimerdes

In order to maintain stationary values of the stored energy and the plasma current in a tokamak discharge with all of the current driven noninductively, the sum of the α-heating power and the power required to provide externally driven current must be equa ...

Analysis Of An Active Magnetic Regenerator Made Of Gadolinium Wires

Didier Albert Simon Vuarnoz

During the last century, the MagnetoCaloric Effect (MCE) has been widely used for realizing extremely low temperatures. However, it is only in the last three decades that some of the efforts to develop a benign and cutting-edge technology for realizing the ...

On the locality of MHD turbulence scale fluxes

The scale locality of energy fluxes for magnetohydrodynamics (MHD) is investigated numerically for stationary states of turbulence. Two types of forces are used to drive turbulence, a kinetic force that acts only on the velocity field and a kinetic-inducti ...

Large-Eddy Simulation of Wind-Turbine Wakes: Evaluation of Turbine Parametrisations

Fernando Porté Agel, Yu-Ting Wu

Large-eddy simulation (LES), coupled with a wind-turbine model, is used to investigate the characteristics of a wind-turbine wake in a neutral turbulent boundary-layer flow. The tuning-free Lagrangian scale-dependent dynamic subgrid-scale (SGS) model is us ...

Biosensing and actuation for microbiorobots

Mahmut Selman Sakar

In this paper, we describe how signaling networks and actuation in bacterial cells and biomolecular networks of bacteria can be used to develop an integrated micro-bio-robotic system. SU8 microstructures blotted with swarmer cells of Serratia Marcescens in ...

Optimisation des stratégies de réglage d'une installation de pompage-turbinage à vitesse variable

Yves Pannatier

Important modifications of the electricity generation landscape are expected in the next decades. This is mainly due to the increase of the demand, the limitation of traditional resources as fossil fuel energy resources and the development of renewable ene ...

Start-up and Synchronization of a Variable Speed Pump-Turbine Unit in Pumping Mode

Jean-Jacques Simond, Christophe Nicolet, Basile Kawkabani, Yves Pannatier, Alexander Schwery

This paper presents the start-up and synchronization procedures of a variable-speed pump-turbine unit of 250 MW in pumping mode. These procedures applied to a doubly-fed induction motor-generator with three-level voltage source inverters VSI cascade in the ...

Flow recirculation when pumping liquids with AC electric fields: experiments and simulations

Nico de Rooij, Luca Ribetto

Many popular micropumps implement moving parts that presents serious drawbacks. This is one of the reasons for the growing interest in valveless micropumps. Pumps exploiting AC electric fields are investigated here. Theoretical results are recalled and the ...

High-Speed Power System Stability Simulation Using Analog Computation

Maher Kayal, Laurent Fabre, Ira Nagel

This paper presents a microelectronic emulation approach for high-speed power system computation. First, the problems of existing power system simulators are detailed. This shows that microelectronic emulation is a possible solution for solving the speed p ...
