Design and analysis for efficient simulation in petrochemical industry
(North-West University, 2008)
Building an industrial simulation model is a very time and cost intensive exercise because these models are large and consist of complicated computer code. Fully understanding the relationships between the inputs and the ...
Benchmarking IT service regions
(North-West University, 2008)
Productivity and efficiency are the tools used in managing performance. This study researches and implements best practices that lead to best performance. A customer quality defined standard has to be created by benchmarking ...
The application of selected invertebrates as indicators of ecosystem change due to veld fires
(North-West University, 2008)
The quality of terrestrial invertebrates as indicators for the detection of ecological change associated with disturbance is widely acknowledged. Invertebrates, at the community level, are often more sensitive to changes ...
Host plant resistance as a management tool for Ditylenchus africanus (Nematoda : Tylenchidae) on groundnut (Arachis hypogaea)
(North-West University, 2008)
Groundnut is an important cash crop both for commercial and smallscale farmers in South Africa. The effect of Ditylenchus africanus on groundnut is mainly qualitative, leading to downgrading of groundnut consignments. This ...
The role of vegetation in characterising landscape function on rehabilitating gold tailings
(North-West University, 2008)
Gold mine waste poses a significant challenge for rehabilitation practitioners and can negatively impact on soil, air, surface water and groundwater quality. This, in turn, can affect the environmental quality of humans ...
Aspects of amphibian chytrid infections in South Africa
(North-West University, 2008)
The waterborne pathogen Batrachochytrium dendrobatidis (Bd), amphibian chytrid, is
implicated as being the causative agent for global amphibian declines. The fungus attacks the keratinized skin of adult and postmetamorphic ...
Optimal provisioning for deposit withdrawals and loan losses in the banking industry

With the acceptance of the new Basel II banking regulation (implemented in South Africa in January 2008) the search for improved ways of modeling the most important banking activities has become very topical. Since the ...
A place-making approach to spatial planning of rural landscapes : the Vredefort Dome World Heritage Site as a case study
(North-West University, 2008)
In its course of development, urban and regional planning has been greatly influenced by the modernist movement, which left human environments with various problematic ecological and social conditions. In reaction to these ...
Bank loan pricing and profitability and their connections with Basel II and the subprime mortgage crisis
(North-West University, 2008)
A topical issue in financial economics is the development of appropriate stochastic dynamic models for banking items and behavior. The issue here is to fulfill the need to generalize the more traditional discrete-time ...
The evaluation of different technologies to restore old cultivated lands
(North-West University, 2008)
As production costs for the cultivation of cash crops increased and government subsidies for farmers decreased and eventually stopped, the farmers stopped to cultivate the marginal to lower potential soils. The higher input ...
