This paper describes the working principle of a DC magnetohydrodynamic (MHD) micropump that can be operated at high DC current densities (J) in 75-μm-deep microfluidic channels without introducing gas bubbles into the pumping channel. The main design featu ...
We report results on electric DC-field induced and self induced recovery of the switched remanent polarisation (P-r(s)) in fatigued ferroelectric thin films. The field induced recovery is characterised by a strong asymmetry and depends on the ratio between ...
Compares five lightning return stroke current models that exhibit a simple relationship between the current at the return stroke channel-base and the current along the return stroke channel, namely the Bruce-Golde (BG) model, the transmission line (TL) mod ...
Especially when a three-phase or single-phase circuit contains at least one capacitor and one saturable inductance, the waveform of the periodic voltages and currents in this circuit can reach several different values (depending on the initial conditions) ...
We have investigated the magnetoresistance of metal-semiconductor hybrid structures at 4.2 K. The devices consisted of polycrystallineAu and an InAs-based heterostructure that hosted a high-mobility two-dimensional electron system. We have varied the elect ...
The paper is a contribution to the studies of factors that can affect electric (E) and magnetic (H) fields associated with lightning return strokes to tall structure. Herein, the influence of lightning channel inclination upon vertical E-field and azimutha ...
The present paper describes a new parameter identification method for induction machines. This method requires only a start-up test during which speed as well as stator currents and voltages are measured. The processing ot these quantities by identificatio ...
We present a numerical study of the electrostatic wobble motor. Both finite- element calculations and analytical approaches are used to calculate the torque exerted by the electrodes. Both methods give very similar results, validating an analytical approac ...
Density limit disruptions have been studied during the current flat-top of TCA. Disruption occurs at two different densities, depending on discharge programming. The highest densities are achieved by a strong influx of neutral gas called 'hard gas puffing' ...
