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 ...
Modelling of VLF radio propagation in the earth-ionosphere waveguide.
Abstract available in PDF file.
Progress with the colliding shock lens.
The Colliding Shock Lens (CSL) exploits the interference of shock waves in a gas to form a region in which high pressure, temperature and density change the refractive index of the gas, making it possible to focus laser ...
The evolution of orbital-angular-momentum entanglement of photons in turbulent air.
Quantum entanglement plays an important role in the emerging quantum information processing and communications tasks. To this day, almost all these tasks use quantum systems described by a two dimensional Hilbert space ...
Monitoring the states of single quantum systems.
Continuous weak measurement provide a convenient way to gather information about a quantum system without the need to prepare huge ensembles of identical systems as required by standard quantum measurement theory. Even ...
An investigation of high velocity flows in HF radar data during northward interplanetary magnetic field, non-substorm intervals.
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 ...
Profile analysis of X-ray powder diffraction data.
Various strategies have been tested for obtaining integrated intensities from x-ray powder diffractometer data. An asymmetric pseudo-Voigt profile function was used to fit the pattern in the region above 2θ = 35̊ (Cu-Kα ...
