A study of the turn-on mechanisms in thyristors
… the ‘on’ plasma spreading velocity to the small signal current gain value of the n-p-n transistor section of the thyristor. The extent to which the thyristor turns on initially largely affects the speed of turning-on the device. A model is proposed to calculate the initial turned-on area of …

Alternate configurations for blocked impurity band detectors
… modes for GaAs BIB detectors in order to bypass current fabrication issues. The numerical simulations provide an understanding of the fundamental physics that governs detector transport. The proposed alternatives to standard operation are created by reversing the detector's bias and varying the …

PLL-based active optical clock distribution
… for logic propagation. Processor designers currently employ several types of electrical deskew mechanisms to combat this problem in order to delay the inevitable need for more radical clocking solutions. Optical clock distribution has the potential to deliver extremely high precision global …

Steady and unsteady visco-resistive reconnection in the presence of the Hall effect
… set of initial conditions. These singularities signal current sheet formation. We consider a general set of initial conditions and find that the singularities will form in this self-similar solution unless the axial field is many orders of magnitude larger than the planar field. In Chapter 5, we …

Switched beam array antenna for 2.45 GHz RFID localisation
… of research as they add further capabilities to current RFID systems. Localisation allows the position of tagged items to be determined from the RFID communications signal. Current systems can confirm that a specific item is within the reader read range but finding the item requires a systematic …

Neural networks applied to ocean colour remote sensing for environmental monitoring
… a concentration from remote sensing. The light signal measured from satellites needs to be corrected for various atmospheric and water surface effects. After atmospheric correction, the water leaving signal can be isolated and different algorithms exist to retrieve chlorophyll a. In open waters, …

Modeling Transit Vehicle Travel Time Components for Use in Transit Applications
… system users, operators and agencies is Transit Signal Priority (TSP). TSP favors transit vehicles in the allocation of green times at traffic signals. A successful deployment of TSP depends on different factors including the prediction of various components of transit vehicle travel times to …
