The aim of this paper is to report on recent advances made in global gyrokinetic simulations of ion temperature gradient (ITG) modes and other microinstabilities. The nonlinear development and saturation of ITG modes and the role of E x B zonal flows are s ...
A disposable micropump is presented that uses the piston actuation principle and relies on the magnetic properties of a ferrofluid, a colloidal suspension of nanosize ferromagnetic particles. The cost effective micropump consists of 7 bonded layers of poly ...
Recent International Thermonuclear Experimental Reactor (ITER) Model Coils and tests on Nb-3 So Cable in Conduit Conductors (CICC) showed a significant and unexpected increase in the broadness of the transition to the normal state, resulting in degradation ...
This publication presents the application of Non-Linear Programming (NLP) to the design of AC induction motors driving hydraulic pumps on commercial aircrafts. In addition to the usual constraints on the geometry or on the efficiency of the motor, the spec ...
High speed rotation of small rotors is needed more and more in many industrial applications. Classical examples are compact devices like scanners, gyroscopes, centrifuge units and so on. The key to achieve high rotating speeds is to have contactless bearin ...
It is possible to determine the types and values of stator and rotor errors in magnetic circuits in a synchronous machine by measuring the induced voltage (ui) for the terminals of measurement loops (2) which can capture an image of the induction in the me ...
The operation of the most promising concept for the future fusion rector, tokamak, relies on the generation of plasma current. Traditionally, this is created by magnetic induction which makes the tokamak operation pulsed. With electro-magnetic waves, in th ...
We present in this paper experimental results obtained at the International Center for Lightning Research and Testing (ICLRT), Camp Blanding, Florida, where currents induced by triggered and natural lightning events were measured at one end of a shielded b ...
A configurable converter topology is presented as front-end converter for a locomotive that can be operated as well on a high voltage ac-system as on a medium voltage dc-system. The configurable converter is realized on the base of a multilevel chain, wher ...
Due to the opening or closing operation of circuit breakers and disconnected switches in gas-insulated substations (GIS), a very strong transient wave process can be generated along the three-phase transmission system and transient electromagnetic field ca ...
