An experimental study of diamond and the nitrogen vacancy centre as a source of single photons.
For applications in Quantum Information and Quantum Key Distribution an on-demand source of single photons is desirable because absolute security is of utmost importance. Photons are quantum systems; hence encoding information ...
Digital, statistical and wavelet study of turbulence flow structure in laboratory plunging water waves.
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. ...
Measurement of soil in sugar cane using non-destructive techniques.
The soil being delivered with sugar cane consignments. from the cane fields to the factories, has been a recent cause for concern in the South African sugar industry. The soil impurities increase the wear of processing ...
The measurement of electric quadrupole moments of gas molecules by induced birefringence.
Determining the electric quadrupole moments of gas molecules from measurements of birefringence induced in the gas by an applied electric field gradient is widely recognised as being the most direct experimental technique ...

Mossbauer spectroscopy and x-ray diffraction study of (Cd, Zn) substituted mixed ferrites.
The study of magnetic properties and structures of Zn and Cd substituted mixed ferrites has been carried out using Mossbauer spectroscopy and X-ray diffraction on powdered samples at about 300 K. Two series of mixed ...
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 ...
Aurora and associated VLF phenomena.
Observations have been made at Sanae (gm. lat. -63,71°) on occurring auroral forms, (diffuse and pulsating aurora), and simultaneous occurring VLF phenomena, (whistlers and auroral hiss) . Two studies ...
