Modeling the effects of environmental and ecological processes on the transport, mortality, growth, and distribution of early stages of cape anchovy (engra ulis encrasicolus) in the Benguela system
(University of the Western Cape, 2003)An individual based modeling approach was used to study environmental factors and processes influencing the early life history of anchovy in the southern Benguela region and on the Agulhas Bank. The intention was to then ... -
Modelling and measurement of radon diffusion through soil application on mine tailings dams.
(University of Western Cape, 2004)Radon (222Rn) has been identified as an important factor that could result in a health hazard by studies all around the world. The health risks can be minimised by preventive measures where radon is highly concentrated as ... -
Modelling and measurement of radon diffusion through soil for application on mine tailings dam
(University of the Western Cape, 2004)Radon has been identified as an important factor that could result in a health hazard by studies all around the world. The health risks can be minimised by preventive measures where radon is highly concentrated as in some ... -
Modelling of asset allocation in banking using the mean-variance approach
(University of the Western Cape, 2012)Bank asset management mainly involves profit maximization through invest- ment in loans giving high returns on loans, investment in securities for reducing risk and providing liquidity needs. In particular, commercial ... -
Modelling of nonpoint source pollution in the Kuils River catchment, Western Cape - South Africa
(University of the Western Cape, 2008)The Kuils River Catchment is an urban river catchment that forms part of the larger Kuils-Eerste River system draining the eastern half of the Cape Metropolitan Authority area and Stellenbosch Municipality. Rapid urbanisation ... -
Modelling of reliable service based operations support system (MORSBOSS)
(2008)The underlying theme of this thesis is identification, classification, detection and prediction of cellular network faults using state of the art technologies, methods and algorithms. -
Modelling radio galaxies in the Millennium simulation: SKA/MeerKAT sources and CMB contaminants
(University of the Western Cape, 2010)We investigate the modelling of radio galaxies within a semi-analytic framework in the Millennium Simulation of the Virgo Consortium. The aim is to assess the radio sources contamination of Sunyaev-Zeldovich (SZ) signatures ... -
Modelling risk factors related to the performance of two oceans half marathon runners between 2012 and 2015
(University of the Western Cape, 2022)Limited literature is available on the effect of factors associated with the improvement in performance of Two Oceans Half Marathon (TOHM) runners. This study examined factors associated with the improvement in performance ... -
Modelling the basel III capital adequacy and net stable funding ratios for a commercial bank following an optimal investment strategy
(University of the Western Cape, 2024)Commercial banks have a significant impact on a country’s economy as they raise capital, create liquidity by converting their customers’ deposits into loans, and deliver essential services such as loans, certificates of ... -
Modelling the behaviour and fate of priority pesticides in South Africa
(University of the Western Cape, 2005)The use of pesticides poses a serious threat to the limited water resources of South Africa. The amounts which are not taken up by crop plants, are often washed away by runoff into surface waters, or leached through the ... -
Modelling the growth of large-scale structure with interacting fluids
(University of the Western Cape, 2015)Prevailing astronomical and astrophysical observations suggest that we live in a spatially flat cold dark matter (CDM) universe - currently going through a period of accelerated expansion possibly driven by “dark energy” ... -
Models and applications of wireless networks in rural environments
(University of the Western Cape, 2005)With the unprecedented growth of the communication industry that the world is experiencing, the demand from rural inhabitants for high quality communications at an economically affordable cost is growing. However, rural ... -
Modification of nanostructured carbon based supports for direct methanol fuel cells
(University of the Western Cape, 2022)Palladium (Pd) and Palladium-Ruthenium (Pd-Ru) nanoparticles supported by various carbon nanomaterials which include graphene oxide (GO), reduced graphene oxide (rGO) and multiwalled carbon nanotubes (MWCNTs) with their ... -
A modified Adams fusion method for the synthesis of binary metal oxide catalysts for the oxygen evolution reaction
(University of Western Cape, 2020)The majority of the global energy is sourced from conventional fossil fuels. The high demand for energy is accelerating along with the depletion of these fossil fuels. Hence, the shift to renewable energy sources and ... -
The modulating effect of conjugated linoleic acid (CLA) on cancer cell survival in vitro
(University of the Western Cape, 2014)Conjugated linoleic acids (CLA) are geometrical and positional isomers of n-6 octadecadenoic acid (linoleic acid, LA, 18:2n-6), which form part of a family of essential polyunsaturated fatty acids (PUFA). There are 28 ... -
The modulating effect of fatty acids on the lipid profile in colon epithelial mucosa in Vivo
(University of the Western Cape, 2009)Several abnormal conditions, including some cancers, have been associated with changes in the membrane lipid and FA composition. Dietary fat serves as a major source of lipids and FA, particularly the polyunsaturated fatty ... -
Modulation of brassica rapa L. antioxidant activities by exogenous methylglyoxal under zirconium stress
(University of the Western Cape, 2016)With a decrease in water availability and arable land, and the ever-increasing reports of toxic chemical pollutants, it is crucial to elucidate plants’ mechanisms of adaptability to these abiotic stressors. South Africa ... -
