A model for the calculation of lightning-induced voltages is presented with the aim of assessing the effect of corona when power distribution lines are illuminated by lightning electromagnetic fields. Corona is taken into account by means of dynamic capaci ...
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) ...
The purpose of this study is to assess the expected response of conventional and non-conventional quench detection sensors proposed for the ITER coils, and to be tested in the QUELL experiment in SULTAN. The assessment is based on simulation of thermo-hydr ...
This work experimentally demonstrates that the negative capacitance effect can be used to significantly improve the key figures of merit of tunnel field effect transistor (FET) switches. In the proposed approach, a matching condition is fulfilled between a ...
In microprocessor-based systems, large power savings can be achieved through reduction of the transition activity of the on- and off-chip busses. This is because the total capacitance being switched when a voltage change occurs on a bus line is usually sen ...
Piezoelectric ZnO coatings on optical fibers are of interest for active optical-fiber devices such as phase and wavelength modulators. Reactive magnetron sputtering has been used to prepare high-resistivity [001] radially oriented ZnO coatings on 85 mm lon ...
The electrical behavior of Au/SiOx/n-GaAs Schottky structures has been studied using a statistical approach. II has been concluded that the obtained unusual electrical behavior is connected mainly with different Fermi-level pinning position and lateral mic ...
Boltzmann electron energy distribution poses a fundamental limit to lowering the energy dissipation of conventional MOS devices, a minimum increase of the gate voltage, i.e. 60 mV, is required for a 10-fold increase in drain-to-source current at 300 K. Neg ...
