A Finite-Difference Time-Domain Electromagnetic Solver in a Generalized Coordinate System
… the simulation of full-wave electromagnetic wave propogation in complex structures is developed. This method is simple and flexible; it allows for the simulation of transient wave propogation in a large class of practical structures. Boundary conditions are implemented for perfect and imperfect …

Tunable liquid microlenses formed from dynamically re-configurable double emulsions
… would enable unprecedented control of light propogation on the microscale. Double emulsions formed from immiscible hydrocarbons and fluorocarbons offer a promising platform as reconfigurable micro-optical lenses. These droplet-based lenses can be reconfigured to strongly focusing, nearly …

Performance analysis of HDLC protocol operating in asynchronous balanced mode
… on both the links. Satellite links have long propogation delays compared to terrestrial links, and hence, have longer error recovery times. For such links, errors in acknowledgements have considerable impact on the throughput. In this analysis, the effect of errors in acknowledgements is taken …

Semiclassical Scattering for Two and Three Body Systems
… we provide a rigorous result concerning the time propogation of a semiclassical wavepacket over the time domain -∞ < t < ∞. This result has long been known for dimension n ≥ 3, and we extend it to one and two space dimensions. Next, we present a brief mathematical discussion of the three body …

Root suckering in Dichrostachys cinerea and a comparison of subspecies africana and nyassana
… herbivory. There was no difference in vegetative propogation by root suckering in areas of different fire regime, rainfall, soil type or degree of herbivory. The implication is that the management of the species will be a formidable task. A combination of burning during summer, when below ground …

Human response to vibration from earthmoving machines.
… was established as the direction of vibration propogation presenting greatest potential risk. The principal reference was IS02631:1978(E) and acceleration levels were measured at frequencies up to 100 Hertz for analysis and comparison. A proposed 'comfort factor' investigation was omitted after …

The vertical structure of the wind-driven circulation
… of the currents within it. In chapter 4 the propogation of Rossby wave trains through slowly varying forced mean flows is examined by solving the linearized potential vorticity equation using the WKB method. If the mean flow is forced the action defined by Bretherton and Garrett (1968) is not …

A biogeographic analysis of the species Fragaria vesca using microsatellite markers on a worldwide plant collection
… from its small genome as well as both easy propogation and maintainance. A vast collection and research on natural variation is imperative to the advancement of research in the field of the Rosa (Rosaceae) plant family, the third most economically important of all plant families. Another …

Orbital Determination Feasibility of LEO Nanosatellites Using Small Aperture Telescopes
<p>This thesis is directed toward the feasibility of observing satellites on the nano scale and determining an accurate propagated orbit using a Meade LX600-ACF 14” diameter aperture telescope currently located on the California Polytechnic State University campus. The optical telescope is fitted …

A Comparative Study of Degenerative Tissue
… The objects of nutrition are growth, repair, and propogation. The amount of matter expelled from the body must be equaled by the amount of nourishment taken into the body in order to make these objects possible, and if from any course the nutrition is impaired, the animal tissue suffers. This …

Laboratory and field trials evaluation of transmit delay Diversity applied to DVB-T/H networks
The requirements for future DVB-T/H networks demand that broadcasters design and deploy networks that provide ubiquitous reception in challenging indoors and other obstructed situations. It is essential that such networks are designed cost-effectively and with minimized environmental impact. The …

Identification of novel determinants of primary and acquired resistance to EGFR-targeted therapies in colorectal cancer
… in the proliferation of cancer cells and propogation of the tumour. One major caveat of the use of these targeted therapies is the existence of resistance, rendering these treatments ineffective. Resistance towards targeted therapies can exist innately within the tumour or can develop over …

Power Transmission Loss Due to Periodic Loading In Multi-Gigabit Data Signaling Interconnects
<p> Printed Circuit Boards (PCBs) provide the primary signal interconnect medium in current computer systems. Silicon transistor technology is advancing at a pace predicted by Moore's law. Moving data faster on PCBs will thus need increased signal rates in the near future; signaling rates on PCB …
