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
Classical noise in quantum systems.
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, ...

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 ...
Exactly solvable models for qubits coupled to spin environments : decoherence and entanglement.
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 ...
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 ...
