Interative approaches to convex feasibility problems.
(2001)Solutions to convex feasibility problems are generally found by iteratively constructing sequences that converge strongly or weakly to it. In this study, four types of iteration schemes are considered in an attempt to ... 
An interpretive study of software risk management perspectives.
(2002)This dissertation addresses risk management in the software development context. The discussion commences with the risks in software development and the necessity for a software risk management process. The emergent discourse ... 
Investigating the spatial distribution of diabetes in Africa using both classical and Bayesian approaches.
(2017)Abstract available in PDF file. 
The investigation into an algorithm based on wavelet basis functions for the spatial and frequency decomposition of arbitrary signals.
(1994)The research was directed toward the viability of an O(n) algorithm which could decompose an arbitrary signal (sound, vibration etc.) into its timefrequency space. The well known Fourier Transform uses sine and cosine ... 
An investigation into the use of genetic programming for the induction of novice procedural programming solution algorithms in intelligent programming tutors.
(2004)Intelligent programming tutors have proven to be an economically viable and effective means of assisting novice programmers overcome learning difficulties. However, the largescale use of intelligent programming tutors ... 
Investigation of fertilizer usage in Malawi within the rural livelihood diversification project using generalized linear models and quantile regression.
(2013)Malawi’s economy relies heavily on agriculture which is threatened by declines in soil fertility. Measures to ensure increased crop productivity at household level include the increased use of inorganic fertilizers. To ... 
Investigation of gravitational collapse of generalized Vaidya spacetimes.
(2015)In this thesis, we study the gravitational collapse of generalized Vaidya spacetimes which describe a combination of lightlike and timelike matter elds, commonly known as Type I and Type II elds, respectively, in the ... 
An investigation of multilabel classification techniques for predicting HIV drug resistance in resourcelimited settings.
(2014)South Africa has one of the highest HIV infection rates in the world with more than 5.6 million infected people and consequently has the largest antiretroviral treatment program with more than 1.5 million people on ... 
Investigation of techniques for automatic polyphonic music transcription using wavelets.
(2009)It has been said (although sadly I have no source) that music is one of the most useful yet useless phenomena known to mankind. Useless in that it has, apparently, no tangible or immediately practical function in our lives, ... 
Iterative algorithms for approximating solutions of variational inequality problems and monotone inclusion problems.
(2017)In this work, we introduce and study an iterative algorithm independent of the operator norm for approximating a common solution of split equality variational inequality prob lem and split equality xed point problem. ... 
A knowledgebased system for automated discovery of ecological interactions in flowervisiting data.
(2017)Studies on the community ecology of flowervisiting insects, which can be inferred to pollinate flowers, are important in agriculture and nature conservation. Many scientific observations of flowervisiting insects are ... 
Leaf recognition for accurate plant classification.
(2017)Plants are the most important living organisms on our planet because they are sources of energy and protect our planet against global warming. Botanists were the first scientist to design techniques for plant species ... 
Lie group analysis of exotic options.
(2013)Exotic options are derivatives which have features that makes them more complex than vanilla traded products. Thus, finding their fair value is not always an easy task. We look at a particular example of the exotic options ... 
Lie symmetries of junction conditions for radiating stars.
(2011)We consider shearfree radiating spherical stars in general relativity. In particular we study the junction condition relating the pressure to the heat flux at the boundary of the star. This is a nonlinear equation in ... 
Likelihood based statistical methods for estimating HIV incidence rate.
(2013)Estimation of current levels of human immunodeficiency virus (HIV) incidence is essential for monitoring the impact of an epidemic, determining public health priorities, assessing the impact of interventions and for ... 
Linear model diagnostics and measurement error
(20100907)The general linear model, the weighted linear model, and the generalized linear model are presented in detail. Diagnostic tools for the linear models are considered. In general the standard analysis for linear models does ... 
Longitudinal analysis of the effect of climatic factors on the wood anatomy of two eucalypt clones
(2010)Eucalypt trees are one of tree species used for the manufacturing of papers in South Africa. The manufacturing of paper consists of cooking the wood with chemicals until obtaining a pulp. The wood is made of different ...
