Classical noise in quantum systems.
(2013)Quantum mechanics contains a fresh and mysterious view of reality. Besides the philosophical intrigue, it has also produced and continues to inspire tantalizing new technological innovations. In any technological system, ... -
Clustering analysis for classification and forecasting of solar irradiance in Durban, South Africa.
(2017)Classification and forecasting of solar irradiance patterns has become increasingly important for operating and managing grid-connected solar power plants. A powerful approach for classification of irradiance patterns ... -
Computational and experimental study of thin films of polymer blends.
(2016)Abstract available in PDF file. -
Computational studies of bond-site percolation.
(2007)Percolation theory enters in various areas of research including critical phenomena and phase transitions. Bond-site percolation is a generalization of pure percolation motivated by the fact that bond-site is close to ... -
Computer simulation of nonadiabatic dynamics by means of the quantum-classical Liouville equation.
(2013)Simulation of quantum dynamics for many-body systems is an open area of research. For interacting many-body quantum systems, the computer memory necessary to perform calculations has an astronomical value, so that ... -
Computer-aided diagnosis in mammography : correlation of regions in multiple standard mammographic views of the same breast.
(2006)Abstract available in PDF file. -
The context of problem tasks in school physical science.
(1999)The purpose of this study was to extend our current knowledge about what happens in physical science classrooms. The focus was the context of problem tasks. This involved the study of the situations, events and factors ... -
Development of encoding and entanglement for free space quantum key distribution.
It is established that the manipulation of quantum information is bound only by the laws of physics and thus information can be characterised, quantified and processed as a physical entity using the basic properties of ... -
Digital, statistical and wavelet study of turbulence flow structure in laboratory plunging water waves.
(2014)This dissertation presents an experimental investigation set out to study the evolution of turbulence in laboratory generated breaking water waves. The waves propagate and break as plunging waves on a 1:20 sloping beach. ... -
The effect of metal nano-composites on the performance of thin film organic solar cells.
(2021)This thesis examines the role of plasmonic nano-particles in the fabrication of thin film organic solar cells (OSCs). Organic solar cells are made up of conducting polymers blend that are formed as ultrathin layers (a few ... -

The effects of traveling ionospheric disturbances on SuperDARN near range echoes.
(2022)Traveling Ionospheric Disturbances (TIDs) and Near Range Echoes (NREs) are both natural phenomena observed by SuperDARN High Frequency (HF) radars. This study presents for the first time observations of NREs in the lower ... -
Electrostatic wave phenomena in dusty plasma.
(1995)This thesis is concerned with the some aspects of electrostatic wave phenomena dusty plasmas. In particular Debye shielding, nonlinear potential structures such as diploar vortices and solitons are investigated. The ... -
The evolution of orbital-angular-momentum entanglement of photons in turbulent air.
(2013)Quantum entanglement plays an important role in the emerging quantum information processing and communications tasks. To this day, almost all these tasks use quantum systems described by a two dimensional Hilbert space ... -
Exactly solvable models for qubits coupled to spin environments : decoherence and entanglement.
(2008)During the last decade the field of quantum information has seen considerable progress both theoretically and experimentally. The building block of this theory is the so-called qubit, the quantum counterpart of the ... -
Experimental investigation and theoretical analysis of the structural relaxation in amorphous Fe40Ni40B20.
(1998)Amorphous metallic alloys are produced by a variety of techniques some of which involve rapid solidification of the alloying constituents. In these methods the solidification occurs so rapidly that the atoms are frozen-in ...
