Measurement and validation of waterlines and surface currents using surf-zone video imaging.
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 ...
Numerical simulation of pressure response in partially completed oil wells.
This work is concerned with the application of finite difference simulation to modelling the pressure response in partially penetrating oil wells. This has relevance to the oil and hydrology industries where pressure ...
Chemical pollution arising from heavy inorganic industries in Richards Bay - an assessment.
The industrial port of Richards Bay on the eastern seaboard of KwaZulu-Natal, South Africa has undergone rapid growth over the last 25 years. This industrial growth has inevitably led to an increase in the anthropogenic ...
Security and entanglement in differential-phase-shift quantum key distribution.
Quantum key distribution (QKD) aims at the creation of a secret key in the two locations of partners, traditionally Alice and Bob, wishing to communicate in private. A generic QKD protocol utilises a quantum channel and ...
The development and testing of computer-aided teaching tools - addressing the conceptual and practical difficulties experienced by first year physics students.
There has been a great deal of research, both locally and abroad, conducted on the learning practices of students at school and at tertiary levels. In an attempt at improving the status of education, some educators have ...
An experimental investigation of the weak-link problem in granular high-Tc superconductors.
Grain boundary weak-link behaviour in superconductors is investigated using a critical state model (CSM), which has been specifically formulated for the applied field range o ~ Ha ~ Hc1g , where Hclg is the intra-granular ...
Multi-wavelength study of radio sources in the universe.
This thesis presents a detailed multi-wavelength study of radio sources. A major part of the thesis focuses on radio sources in the FIRST survey while the latter part of the thesis studies low redshift radio galaxies in ...
Experimental realization of quantum key distribution.
Nowadays, the information society that presides the everyday life is dependent on the communication industry to facilitate unintelligible data transfers between authenticated parties. Human desire to communicate ...
The effect of the f-component of the pseudopotential on selected properties of 5d transition metal systems
Cohesive energies, bulk moduli, and equilibrium lattice constants have been calculated for the 5d transition atoms (Hf, Ta, W, Re, Os, Ir and Pt) in face–centred cubic crystal lattices. We have used the ab initio ...
