1-D particle-in-cell simulations of plasmas with kappa velocity distributions.
(2013)The main aim of this project was the development of a particle-in-cell (PIC) plasma simulation code. While particle-in-cell simulations are not new, they have largely focused on using an initial Maxwellian particle ... -
57 Fe Mössbauer studies of 57 Mn* implanted III-V semiconductors InP and InAs.
(2011)III-V compound semiconductors such as Gallium Arsenide, Indium Phosphide as well as Indium Arsenide have recently demonstrated the capability of applications in high speed semiconductor devices compared to those made from ... -
Analysing transient effects in the ionosphere using narrowband VLF data.
(2009)Very Low Frequency (VLF) radio waves propagate within the Earth-ionosphere waveguide with very little attenuation. Modifications of the waveguide geometry affect the propagation conditions, and hence, the amplitude and ... -
Applications of Lie symmetry analysis to the quantum Brownian motion model.
(2008)Lie symmetry group methods provide a useful tool for the analysis of differential equations in a variety of areas in physics and applied mathematics. The nature of symmetry is that it provides information on properties ... -
Assessment of the efficiency of solar radiation concentrating system.
(2009)A Solar Radiation Concentrating System for generation of high temperature heat for a solar oven was developed and evaluated at the University of KwaZulu-Natal, Westville Campus, Durban - South Africa. The system concentrates ... -
The association between VLF and ELF chorus emissions and electron precipitation.
(2009)This is an investigation into the association between ionospheric absorption caused by electron precipitation and ELF:3 Hz-3 kHz and VLF:3 kHz-30 kHz, chorus. Ionospheric absorption was measured using the chain of riometers ... -
Beam generated instabilities in space plasma.
(1999)Electrostatic instabilities associated with a model applicable to the auroral acceleration region consisting of an ion beam, precipitating electrons and stationary background electrons are theoretically investigated. The ... -
Binary and ternary molecules blend bulk heterojunction organic solar cell.
(2015)Bulk heterojunction organic solar cells were prepared and characterized in terms of electrical and optical properties of the photosensitive medium. Two cases of organic solar cells were developed in this investigation ... -
Bulk heterojunction organic solar cell.
(2014)The low material costs and the ease fabrication procedures of organic solar cells has earned them too much interest from scientists all over the world. Much of the e orts were given to the improvement of the power ... -
Characterisation and quantum application of plasmonic waveguides.
(2016)Plasmonics o ers sub-di raction confinement of light, which a ords enhanced coupling to emitter systems (e.g. quantum dots). This feature makes possible a range of on-chip quantum photonic components - most notably ... -
Characterisation of polarisation-entangled photon source for quantum key distribution.
(2016)Entanglement in real physical systems has been of great interest due to its importance in quantum mechanics. It has applications related to quantum information science speci cally quantum cryptography since it eliminates ... -
Characterization and improvement of a direct solar radiation detector.
(2004)A low-cost Direct Solar Radiation Detector (DSRD) was developed in house in the Department of Physics at the University of KwaZulu-Natal (Westville). A main use of this instrument is to gather solar energy data that are ... -
Chemical pollution arising from heavy inorganic industries in Richards Bay - an assessment.
(2004)The industrial port of Richards Bay on the eastern seaboard of KwaZulu-Natal, South Africa has undergone rapid growth over the last 25 years. This industrial growth has inevitably led to an increase in the anthropogenic ... -
Computational studies of percolation : determination of the cluster number scaling function for lattices in 2 dimensions.
(2010-09-30)The main aim of this work is to study percolation theory on regular two dimensional -
Constant-temperature dynamics in the Wigner representation of quantum mechanics.
(2011)This dissertation deals with theory and algorithms for computer simulations of classical and quantum systems in the canonical ensemble. First, the approach of Nos e-Hoover and its generalization, known as the Nos e- Hoover ... -
Construction and analysis of the receiver for a solar thermal cooker system.
(2013)One of the key components in a solar thermal cooker system is the receiver since the performance of the receiver greatly affects the entire system. Absorption of the maximum amount of reflected radiation is crucial for ... -
Corrosive sulphur in transformers.
(2013)Failures in power transformers, in the majority of cases, have been linked to the formation of copper sulphide (Cu₂S) and corrosive sulphur. Cu₂S is conductive and affects the dielectric properties of the insulation system ... -
The crossfield current-driven ion acoustic instability in a two-ion plasma.
(1987)The behaviour of the crossfield current-driven ion acoustic instability in a plasma containing two ion species is theoretically examined. In our model the electrons are assumed to be hot and the ions cold, i.e. Tₑ »Tᵢ (~ ... -
Determination of quantum entanglement concurrence using multilayer perceptron neural networks.
(2017)Artificial Neural Networks, inspired by biological neural networks, have seen widespread implementations across all research areas in the past few years. This partly due to recent developments in the field and mostly due ... -
