Upper body pose recognition and estimation towards the translation of South African sign language
(University of the Western Cape, 2011)Recognising and estimating gestures is a fundamental aspect towards translating from a sign language to a spoken language. It is a challenging problem and at the same time, a growing phenomenon in Computer Vision. This ... -
Ursolic acid and oleanolic acid as novel therapeutic agents in breast cancer
(University of the Western Cape, 2015)Breast cancer is one of the most common cancers among women in South Africa and the second leading cause of cancer death after lung cancer. According to the American Cancer Society 2015, women have a 12% chance of developing ... -
Usability and content verification of a mobile tool to help a deaf person with pharmaceutical instruction
(University of Western Cape, 2014)This thesis describes a multi-disciplinary collaboration towards iterative development of a mobile communication tool to support a Deaf person in understanding usage directions for medication dispensed at a pharmacy. We ... -
Use and consumer perceptions of dietary supplements in the fitness community of Gaborone, Botswana
(University of Western Cape, 2020)Health authorities around the world, including stringent ones, struggle to regulate dietary supplements. Health claims and actual effects of these products on users therefore are not adequately studied and monitored. In ... -
Use of antioxidant activity and flavonoid levels to assess the quality of commercially available solid dose Sutherlandia frutescens products
(University of the Western Cape, 2010)The overall aims of this project were to assess the pharmaceutical quality and consistency of commercially available solid dose Sutherlandia frutescens containing products (viz. tablets & capsules) by exploring the use of ... -
The use of chemostratigraphy and geochemical vectoring as an exploration tool for platinum group metals in the Platreef, Bushveld Igneous Complex, South Africa : a case study on the Tweefontein and Sandsloot farms
(University of the Western Cape, 2015)The Platreef is known for its complexity and its heterogeneous lithologies, coupled with an unpredictable PGE and BMS mineralisation. The motivation behind this study was to aid mining geologists in targeting mineralisation ... -
The use of chemostratigraphy and geochemical vectoring as an exploration tool for platinum group metals in the Platreef, Bushveld Igneous Complex, South Africa: a case study on the sandsloot & overysel farms
(University of the Western Cape, 2014)The paucity of geochemical criteria for stratigraphic correlations and defining the styles of mineralisation pose serious problems in locating PGE-rich zones in the Platreef. This study is therefore aimed at identifying ... -
The use of constructed wetlands to ameliorate discharge water from coal mines in the Witbank Coalfield
(University of Western Cape, 2021)Mining has a lengthy history in South Africa, and subsequent beneficiation processes have been conducted with little regard for the environment, thus leaving the land with un-rehabilitated abandoned mines. Currently, most ... -
The use of cyclodextrin template-based metal oxide nanomaterials in the development of electrochemical sensors for phenolic endocrine disruptor compounds
(University of the Western Cape, 2010)Iron oxide nanoparticles were prepared using co-precipitation method in the presence and absence of beta-cyclodextrin β-CD). Such materials were characterized using transmission electron microscopy (TEM), energy dispersive ... -
The use of derivative analysis and aquifer parameter estimation to refine a conceptual model: A case study approach, Western Cape, South Africa
(University of Western Cape, 2021)Hydrogeological characterization of an aquifer system is a first step to determine groundwater quantity, yield potential, socio-economic value, storage capacity and aquifer transmissivity properties of an aquifer as a water ... -
The use of dioxy MP 14 (stabilized aqueous chlorine dioxide) to control environmental airborne microorganisms
(2009)Dioxy MP 14 is a locally developed form of stabilized chlorine dioxide in an aqueous medium. It has all the sanitizing properties of chlorine dioxide gas, a neutral compound of chlorine in the +IV oxidation state, which ... -

The use of FLUENT for heat flow studies of the hot-wire chemical vapor deposition system to determine the temperatures reached at the growing layer surface
(University of the Western Cape, 2009)The overall aim of this project is to study the heat transfer inside the reaction chamber of the Hot-Wire Chemical Vapor Deposition (HWCVD) system with a commercial software package FLUENT6.3; it is one of the most popular ... -
The use of GIS, statistical and risk assessment tools to evaluate aquifer vulnerability to potential contaminants
(The University of the Western Cape, 2017)An aquifer is a body of permeable rock which can contain or transmit groundwater. It is a low cost water supply for domestic and agricultural use. Routine monitoring of aquifers is important to prevent contamination and ... -
The use of mobile phones as service-delivery devices in sign language machine translation system
(University of the Western Cape, 2010)This thesis investigates the use of mobile phones as service-delivery devices in a sign language machine translation system. Four sign language visualization methods were evaluated on mobile phones. Three of the methods ... -
