Feasibility study of ionospheric tomography using HF radar
This thesis gives an outline of the ionosphere and studies that were conducted to investigate
An investigation of ultra low frequency (ULF) pulsations using radar data and solar wind data.
An investigation of Ultra Low Frequency (ULF) pulsations was conducted using data

Fabrication of high efficacy selective solar absobers.
High efficiency tandem selective solar absorber materials of carbon in nickel oxide (C-NiO) composite were fabricated on an aluminium substrate using a simple and cost effective sol-gel process. The process involved ...
An investigation of the efficiency of the receiver of a solar thermal cooker with thermal energy storage.
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 co-ordinates: -29.817897, 30.942771) ...
Construction and analysis of the receiver for a solar thermal cooker system.
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 ...
Structure and bi-magnetism of nanocomposites and nanoalloys synthesized by reduction of (Co, Ni) Fe2O4 nano-ferrites.
Structural and magnetic properties of CoFe2O4, NiFe2O4 nano-ferrites, CoFe2O4 /CoFe2, NiFe2O4/NiFe bi-magnetic nanocomposites and CoFe2, NiFe alloys were studied. The nano-ferrites were synthesised using the glycol-thermal ...
Devices for the construction of a cold atom experiment.
The experimental setup for laser cooling and trapping of 87Rb atoms with the aid of a Magneto-optical trap (MOT) is discussed. The experiment has a diverse setup, which includes: a vacuum system in which the cooling and ...
Generation and detection of bessel beams.
In this dissertation we study the properties of Bessel-Gauss beams. Bessel-Gauss beams are created by the interference of plane waves lying on a cone, and have unique properties: they propagate without spreading and ...
The implementation of polarisation encoded quantum key distribution in fibre.
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 ...
