An Application of Multiple Regression in Exchange Rate Arrangements
(University of the Western Cape, 2008)This project "An application of multiple regression in exchange rate arrangement" focused on the processes followed by different countries when choosing an exchange rate regime for currency stabilization. It analyses the ... -
Application of multivariate statistics and Geographic Information Systems (GIS) to map groundwater quality in the Beaufort West area, Western Cape, South Africa
(UWC, 2013)Groundwater in arid and semi-arid areas like the Karoo region of South Africa is an important source of domestic, agricultural and industrial source of fresh water. As a scarce resource, it requires extensive quality control ... -
The application of novel multinuclear catalysts derived from dendrimeric ligands in the polymerization and oligomerization of unsaturated hydrocarbons
(University of the Western Cape, 2007)G1 and G2 dendrimeric salicylaldimine ligands containing both substituted and unsubstituted aryl rings were synthesized via a Schiff base condensation of the appropriate salicylaldehyde and the peripheral amino groups of ... -
Application of petrophysics and seismic in reservoir characterization. A case study on selected wells, in the Orange Basin, South Africa
(University of the Western Cape, 2012)The evaluation of petroleum reservoirs has shifted from single approach to an integrated approach. The integration, analysis and understanding of all available data from the well bore and creating property models is an ... -
Application of Several Time Series Methods to Three Important Financial Time Series
(University of the Western Cape, 2007)This study is concerned with three different financial time series over an eight year period, namely: the government repurchase rate, the Rand-Dollar exchange rate and the Allshare Index. The aim is to better understand ... -
The application of statistical and machine learning techniques for DDOS detection in network information systems
(University of the Western Cape, 2022)A surge of large-scale Distributed Denial of Service (DDoS) attacks has swept the internet in recent years, possibly presenting a serious threat to industry internet service offerings. These attacks take advantage of ... -
Application of Sutherlandia flutescens in cosmetic skin industry (phytochemical fingerprinting and its activity against skin immune diseases.
(University of the Western Cape, 2019)Hyperpigmentation disorders such as melasma, freckles and black-pigmented spots on the surface of the skin are often a result of increased over production and accumulation of melanin pigments in the skin. In melanin ... -
Application of vertically aligned arrays of metal-oxide nanowires in heterojunction photovoltaics
(University of the Western Cape, 2020)The commercial need to improve the performance of low-cost organic solar cells has led to the idea for this research. The study discusses the synthesis of one dimensional TiO2 and ZnO nanowire arrays synthesised using a ... -
Applications of DNA-barcoding in the identification and understanding of grass invasions in Southern Africa
(University of the Western Cape, 2014)The spread of invasive species is one of the greatest threats to global biodiversity. Alien plant invasions also have serious economic impact in terms of the delivery of ecosystem goods and services. Studies of biological ... -
Applying a lagrangian trajectory model to investigate and describe the distribution of drifting ecklonia maxima within the benguela upwelling system
(University of the Western Cape, 2023)Macroalgal morphological variation is determined to a large extent by a combination of environmental factors, with wave exposure and temperature perhaps the main influences, as they are key environmental properties to which ... -
An approach to acquifer test pumping in fractured crystalline aquifers with a case study in Namaqualand
(University of the Western Cape, 2002)Water resources in South Africa are being stressed. Due to this concern more emphasis should be placed on determining where we can improve our existing methods for the calculation of sustainable yield. Current approaches ... -
An approach to groundwater targeting in the Springbok region, central Namaqualand, Northern Cape Province, South Africa
(University of the Western Cape, 2003)Namaqualand is a semi-arid region where water is not only a necessity and basic need, but also very much a luxury. As a consequence, various studies were undertaken to find water sources, whether surface or groundwater, ... -

Aptamer selection against GFRa1 for its application in the prognosis of breast cancer
(University of the Western Cape, 2019)Breast cancer is the second most common cancer amongst South African women. Despite ongoing efforts to combat breast cancer, current prognostic and/or therapeutic monitoring methods are limited since very little improvement, ... -
Arenas of contestation: policy processes and land tenure reform in post-apartheid South Africa
(University of the Western Cape, 2008)Summary: This thesis considers different groupings that have come together in their participation in the policy processes relating to tenure reform in post-apartheid South Africa. It is methodologically and theoretically ... -
Articulated structure from motion
(University of the Western Cape, 2004)The structure from motion (SfM) problem is that of determining 3-dimensional (3D) information of a scene from sequences of 2-dimensional (2D) images [59]. This information consists of object shape and motion and relative ... -
Aspects of the gastrointestinal uptake and metabolism of luteolin derivatives from Artemisia afra aqueous extract (preclinical)
(University of the Western Cape, 2011)The aim of this study was to investigate the effect the plant matrix and the structure of the flavonoid (i.e. whether aglycone or glycoside) may have on the gastrointestinal uptake and metabolism of luteolin derivatives ... -
Aspects of the interrelation between hypertension and insulin resistance
(University of the Western Cape, 2009)Conclusion of this study: These data suggest that 6 weeks of high-fat feeding induces hypertension but does not produce obesity, dyslipidemia and insulin resistance. However, this model may be useful in studying vascular ... -
Aspects of the interrelation between hypertension and insulin resistance: a preliminary study
(2009)Background: It is well known that some genetic factors and dietary factors, such as excessive salt intake and excessive caloric intake (resulting in obesity) are risk factors for hypertension. Fifty percent of all ... -
Aspects of the reproduction of male and female African penguins (Spheniscus demersus) with special reference to sperm biology and cryopreservation
