In this paper, a high current pulse power supply for the feeding of a flash lamp has been developed, on the base of a multilevel converter with cascaded cells. The pulsed high power is provided by capacitive energy storage, directly connected to the cells ...
In this paper, we present an analysis of the lightning events preceding initiation of upward lightning flashes from the Gaisberg and the Santis Towers. It is found that the majority of upward lightning discharges from both towers are initiated without any ...
In the main part of this thesis, I investigate the neural correlates of nonretinotopic processing. We might intuitively think of the visual representation of the world as retinotopic, as is the case for the organization of most visual brain areas, but in f ...
In this thesis, a new experimental station was designed and built for the measurement of lightning currents. The station (Säntis Tower) was instrumented using advanced and modern equipment with remote monitoring for an accurate measurement of lightning cur ...
A reactor using localized remote plasma in a grid electrode is presented in this study. The aim is to reduce the ion bombardment energy inherent in RF capacitively coupled parallel plate reactors used to deposit large area thin film silicon solar cells. Hi ...
The majority of the research on cavitation luminescence has focused on the sonoluminescence or chemiluminescence generated by cavitation induced through ultrasound, with a lesser body of work on the luminescence induced by laser- or spark induced cavitatio ...
Titanium aluminium nitride (TiAlN)-based coatings are designed specially for applications where oxidation and wear resistance are primary demands, as in the case of cutting tools. Moreover the coatings are required to be thermally stable as well as have go ...
The goal of the paper was to analyze the current distribution of a high-power salient-pole synchronous machine damper winding. A few methods were considered but only two analytical methods are highlighted. Both methods arc based on parameter calculation by ...
The effect of field reversal on the JET MkIIGB-SRP divertor performance has been investigated in L-mode density limit discharges. These experiments show that the direction of the magnetic field has a substantial effect on divertor physics, modifying the ch ...
The fluctuating behaviour of a Sulzer Metco F4 DC plasma gun has been investigated. The time dependencies of the arc voltage and current and of the optical emission of the plasma jet have been measured. An optical fibre inside the gun allows direct measure ...
