Magnetic properties of Mg₁-xZnxFe₂O₄ nanoferrites and tetracycline-ferrite 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 ... -
Mass spectrometry characterisation of laser produced products.
(1999)Mass spectrometers are analytical instruments that convert neutral atoms and molecules into gaseous ions and separate those ions according to the ratio of their mass to charge, m/z. The measurement is reported as a ... -
Measure-preserving and time-reversible integration algorithms for constant temperature molecular dynamics.
(2011)This thesis concerns the formulation of integration algorithms for non-Hamiltonian molecular dynamics simulation at constant temperature. In particular, the constant temperature dynamics of the Nosé-Hoover, Nosé-Hoover ... -
Measurement and computational modelling of intermolecular interactions in fluids.
(2000)The molecular theory of the second light-scattering virial coefficient Bp describing the effects of interacting pairs of molecules on the depolarization ratio p of Rayleigh-scattered light is reviewed, both for interacting ... -
Measurement and modelling of the directional scattering of light.
(2015)The quantum nature of light suggests that a photon can interact with matter in two primary ways. Firstly and perhaps more simply, the photon could be absorbed or secondly and more complex, it could be scattered into a ... -
Measurement and validation of waterlines and surface currents using surf-zone video imaging.
(2001)The continuous monitoring of beaches and structures near, or in the surf-zone, has become a vital task from an environmental and economic standpoint. Specifically, the Durban beaches are continually nourished with sand ... -
The measurement of electric quadrupole moments of gas molecules by induced birefringence.
(1993)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 ... -
Measurement of soil in sugar cane using non-destructive techniques.
(2001)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 ... -
Measurement of the Kerr electro-optic effect by induced birefringence.
(2005)During the period January 2001 to January 2003, M Sc student Mr Tleyane Jonas Sono developed an apparatus to measure the pressure- and temperature-dependence of the electro-optic Kerr effect (electric-field-induced ... -
Measurement of the temperature dependence of the Buckingham effect (electric-field-gradient-induced birefringence) in gases
(2009)The aim of this research project was to assemble an apparatus to measure the electric quadrupole moments of gas molecules using the technique of electricfield- gradient-induced birefringence, or the Buckingham effect. ... -
Mesosphere-lower thermosphere planetary and tidal waves structure over the southern hemisphere using SANAE and Halley SuperDARN HF radar.
(2015)Abstract available in PDF file. -
Microcontroller based data acquisition and control of a solar thermal energy system.
(2009)A solar thermal energy system is being rebuilt at University of KwaZulu-Natal School of Physics. A similar system is also being built in the University Eduardo Mondlane – Maputo Mozambique, in a team development work. ... -
Modeling of fabricated NiO/TiO2 P-N heterojunction solar cells.
(Research India Publications., 2018)This paper reports modelling and theoretical validation of a fabricated NiO/TiO2 P-N heterojunction solar cell. The solar cell equations were modelled and thereafter theoretical validation of the fabricated solar cells was ... -
Modelling diode-pumped solid-state lasers.
(2008)This thesis consists of three main parts. An introduction to diode-pumped solid-state lasers, thermal modelling of solid-state lasers and rate-equation modelling of solid-state lasers. The first part explains the basic ... -
Modelling of the ballooning instability in the near-earth magnetotail.
(1995)In recent years, many alternative models of the substorm process have been proposed to explain different aspects of this magnetospheric phenomenon. Some features in these competing models are compatible while others, such ... -
Modelling of VLF radio propagation in the earth-ionosphere waveguide.
(2012)Abstract available in PDF file. -
Modelling the interaction between human immunodeficiency virus, mycobacterium tuberculosis and the human immune system, including the effects of drug therapy.
(2007)Tuberculosis (TB) is the leading cause of death in individuals infected with human immunodeficiency virus (HIV) in several African countries, including South Africa. HIV-positive individuals do not have the immune system ... -
Monitoring the states of single quantum systems.
(2012)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 ... -
Monte Carlo simulations in open quantum systems.
(2007)The motivation for this Masters thesis is to develop numerical algorithms to study the dynamical evolution of non-Markovian open quantum systems. Such systems are of importance if one is interested in modeling solid state ...
