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 ...
Feasibility study of ionospheric tomography using HF radar
This thesis gives an outline of the ionosphere and studies that were conducted to investigate
Transverse modes in porro prism resonators
This dissertation consists of two main sections. The first is a review of laser resonators using spherical mirrors, and incorporates a physical optics numerical model of a Fabry-Perot laser resonator without gain. The ...
Equilibrium properties of some high-temperature superconductors.
An important fundamental problem in the understanding of the high-Tc superconducting systems is the determination of their equilibrium magnetization behaviour, in particular their constitutive Brev(H) orMrev(H) behavior. ...
Towards practical quantum cryptography.
The information society that presides today is dependent on the communication industry to facilitate unintelligible data transfers between authenticated parties. Such requirements have, to date, taken advantage of security ...
Extracellular potentials from action potentials of anatomically realistic neurons and neuronal populations.
Extracellular potentials due to firing of action potentials are computed around cortical neurons and populations of cortical neurons. These extracellular potentials are calculated as a sum of contributions from ionic ...
The fluorescent tube-lamp integrating chamber.
The objective of this project is to design a facility that will characterize the electrical and optical properties of both tubular and the more recent compact fluorescent tubes. The first stage of this project, which is ...
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
Vacuum vessels in tension.
Tensional Vacuum Vessels (TVV) are vessels constructed such that the walls are placed in tension rather than in compression as is the case with conventional vacuum vessels. TVVs have the advantage of being cost-effective, light ...
Figure rotation of dark halos in cold dark matter simulations.
We have simulated structure formation on cosmological-scales using N-body simulations run on the University of KwaZulu-Natal's cluster of computers and have used these simulations to investigate aspects of galaxy evolution. ...
