Aerosol characteristics over different regions of southern Africa : using sunphotometer and satellite measurements.
(2015)Aerosols and cloud play a major role in understanding and interpreting the varying earth’s energy budget. It is necessary to characterize these atmospheric particles by their sizes, chemical composition, water content etc. ... -
An analysis of Pc5 pulsations observed in the SuperDARN radar data.
(2009)This thesis deals with the development of automatic methods for nding pulsation events in time series produced by the radars in the SuperDARN network. These methods are then applied to the detection and analysis of ... -
Application of machine learning techniques to the description of open quantum systems.
(2023)This work focuses on using classical machine learning (ML) models to study the quantum dynamics of excitation energy transfer (EET) within strongly coupled open quantum systems relevant to light harvesting complexes ... -
Applications of digital holograms for the selection and detection of transverse laser modes.
(2014)The transverse mode of generally available commercial lasers in most instances is not suitable for desired applications. Shaping the laser beam either extra-cavity, that is outside the laser resonator, or intra-cavity, ... -
Applications of light scattering and refraction by atmospheric gases.
(2002)LIDAR, an acronym for LIght Detection And Ranging, is a system used for studying the scattering of laser light incident on a parcel of air. This thesis investigates the atmosphere above the Durban region using two ... -
Aurora and associated VLF phenomena.
(1978)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 ... -
Baseline demand responsiveness framework for the conventional grid through appliance scheduling by evolutionary metaheuristics.
(2020)A major problem of many energy environments nowadays, is an obsolete and highly inefficient electricity supply system, the Conventional Grid (CG), characterized by a high peak to average ratio, out of an uncontrollable ... -
Bulk heterojunction organic solar cells and thin film electrode buffer layers : synthesis, preparation and characterization.
(2016)Abstract available in PDF file. -
Characterisation of quantum channels in plasmonic metamaterials and bulk optical systems.
(2018)Quantum channels are key to our understanding of how quantum information can be processed and transmitted. In this respect, over the past decade light has become an important carrier of quantum information. More recently, ... -
Classical noise in quantum systems.
(2013)Quantum mechanics contains a fresh and mysterious view of reality. Besides the philosophical intrigue, it has also produced and continues to inspire tantalizing new technological innovations. In any technological system, ... -
Clustering analysis for classification and forecasting of solar irradiance in Durban, South Africa.
(2017)Classification and forecasting of solar irradiance patterns has become increasingly important for operating and managing grid-connected solar power plants. A powerful approach for classification of irradiance patterns ... -
Computational and experimental study of thin films of polymer blends.
(2016)Abstract available in PDF file. -
Computational studies of bond-site percolation.
(2007)Percolation theory enters in various areas of research including critical phenomena and phase transitions. Bond-site percolation is a generalization of pure percolation motivated by the fact that bond-site is close to ... -
Computer simulation of nonadiabatic dynamics by means of the quantum-classical Liouville equation.
(2013)Simulation of quantum dynamics for many-body systems is an open area of research. For interacting many-body quantum systems, the computer memory necessary to perform calculations has an astronomical value, so that ... -
Computer-aided diagnosis in mammography : correlation of regions in multiple standard mammographic views of the same breast.
(2006)Abstract available in PDF file. -
The context of problem tasks in school physical science.
(1999)The purpose of this study was to extend our current knowledge about what happens in physical science classrooms. The focus was the context of problem tasks. This involved the study of the situations, events and factors ...
