Generalisation of theory and algorithms for the configurational temperature Nosé–Hoover thermostat.
(2015)In this dissertation we reformulate the configurational temperature Nos`eHoover thermostat proposed by Braga and Travis (C. Braga and K.P. Travis, 2005), using the antisymmetric matrix formalism found in (A. Sergi, ... 
Generation and detection of bessel beams.
(20150918)In this dissertation we study the properties of BesselGauss beams. BesselGauss beams are created by the interference of plane waves lying on a cone, and have unique properties: they propagate without spreading and ... 
High repetition rate continuously tunable CO2 laser system investigation.
(1990)The purpose of this thesis was to investigate certain factors important for the operation of a high repetition rate continuously tunable CO2 laser. The tuning range of specific importance for this research program was ... 
The implementation of polarisation encoded quantum key distribution in fibre.
(2012)Quantum Key Distribution (QKD) employs the laws of quantum mechanics for the purpose of cryptography. Two parties, commonly called Alice and Bob, are able to share a random key which is used to encrypt a message. Any ... 
Implementing Grover's search algorithm using the oneway quantum computing model and photonic orbital angular momentum.
(20131010)Standard quantum computation proceeds via the unitary evolution of physical qubits (twolevel systems) that carry the information. A remarkably different model is oneway quantum computing where a quantum algorithm is ... 
Interferometric measurement of induced birefringence in polycrystalline ZnSe.
(2011)The aim of this research project was to assemble an apparatus capable of measuring fieldinduced birefringence in polycrystalline ZnSe. A Michelson interferometric apparatus was assembled, and care was taken to actively ... 
An investigation in the use of satellite data to develop a geomagnetic secular variation model over Southern Africa.
(2011)Time variations of the geomagnetic field can be classified into two main categories of internal and external origin with respect to the surface of the Earth. It has been found that the variations that take place on longer ... 
An investigation of electricfieldgradientinduced Birefringence in fluids.
(20150617)The theory of electricfieldgradientinduced birefringence (EFGIB, the Buckingham effect) is briefly reviewed, and modifications to the Buckinghameffect apparatus are described. These modifications have increased the ... 
An investigation of gas lasers.
(1999)Pulsed lasers have a wide range of applications in industry, medicine and for scientific research. Many of these devices are expensive and have delicate optics. The nitrogen laser is robust and inexpensive to build and ... 
An investigation of high velocity flows in HF radar data during northward interplanetary magnetic field, nonsubstorm intervals.
(2010)Several previous studies, including one using early Sanae radar data, have found examples of high speed ionospheric plasma flows on the nightside, mapping to the magnetospheric tail, during periods which were magnetically ... 
An investigation of the efficiency of the receiver of a solar thermal cooker with thermal energy storage.
(20150105)A small scale solar concentrator cooker with a thermal energy storage system was designed, constructed and tested on the roof of the Physics building at UKZN, Westville campus (GPS coordinates: 29.817897, 30.942771) ... 
An investigation of ultra low frequency (ULF) pulsations using radar data and solar wind data.
(20100910)An investigation of Ultra Low Frequency (ULF) pulsations was conducted using data 
Ionospheric signatures of solar flares.
(2009)VLF waves propagate in the Earthionosphere waveguide (EIW). The EIW is bounded below by the surface of the Earth and above by the ionospheric Dregion (50–90 km altitude). The conditions for wave propagation in the EIW ... 
Kinematics and dynamics of the elliptical galaxy NGC 5266.
(2005)In studies of triaxial elliptical galaxies, one of the least observationally studied phenomena is figure rotation. Figure rotation has important consequences for the orbital structure and could explain the survival of steep ... 
Linear properties of the crossfield ion acoustic instability in a double plasma device.
(1990)This thesis deals with the dependence of the linear spatial growth rate of the crossfield ion acoustic instability on various plasma parameters. A kinetic theory model, with elastic and inelastic ionneutral collisions ... 
Low frequency electrostatic instabilities in a twodust component plasma.
(1999)The kinetic dispersion relation for a magnetized dusty plasma comprising of ions, electrons and massive, charged dust particles is solved for low frequency electrostatic instabilities in the dust plasma frequency ... 
Magnetic properties of Mg₁xZnxFe₂O₄ nanoferrites and tetracyclineferrite nanocomposites.
(2013)Abstract available in print copy. 
Mapping of magnetospheric electric fields from Cluster into ionospheric convection from SuperDARN using the Tsyganenko field model.
(2010)The data from Super Dual Auroral Radar Network (SuperDARN) radar and Cluster was used to investigate whether the processes observed by SuperDARN radar in the highlatitude ionosphere leads to the processes that take place ... 
Measurepreserving and timereversible integration algorithms for constant temperature molecular dynamics.
(2011)This thesis concerns the formulation of integration algorithms for nonHamiltonian molecular dynamics simulation at constant temperature. In particular, the constant temperature dynamics of the NoséHoover, NoséHoover ... 
Measurement and computational modelling of intermolecular interactions in fluids.
(2000)The molecular theory of the second lightscattering virial coefficient Bp describing the effects of interacting pairs of molecules on the depolarization ratio p of Rayleighscattered light is reviewed, both for interacting ...
