A tripartite approach to ensure municipal service delivery. The case of a mining town in South Africa
(CCAU, 2019)
Postmasburg, a small mining town, has been an agricultural centre for the past 120 years, the iron ore mining being the only diversifying factor to the local economy. Mining endeavours resulted in the traditional boom-town ...
Partial and average copulas and association measures
(Institute of Mathematical Statistics, 2015)
For a pair (Y1,Y2) of random variables there exist several measures of association that characterize the dependence between Y1 and Y2 by means of one single value. Classical examples are Pearson’s correlation coefficient, ...
Uniform in bandwidth consistency of kernel estimators of the density of mixed data
(Institute of Mathematical Statistics, 2015)
We establish a general uniform in bandwidth consistency result for kernel estimators of the unconditional and conditional joint density of a distribution, which is defined by a mixed discrete and continuous random variable
A discourse model of affect for text-to-speech synthesis
(Pattern recognition association of South Africa (PRASA), 2013)
This paper introduces a model of affect to improve prosody in text-to-speech synthesis. It operates on the discourse level of text to predict the underlying linguistic factors that contribute towards emotional appraisal, ...
West Africa - a safe haven for frogs? A sub-continental assessment of the Chytrid Fungus (Batrachochytrium dendrobatidis)
(Public Library of Science, 2013)
A putative driver of global amphibian decline is the panzootic chytrid fungus Batrachochytrium dendrobatidis (Bd). While Bd
has been documented across continental Africa, its distribution in West Africa remains ambiguous. ...
Towards lecture transcription in resource-scarce environments
(Pattern recognition association of South Africa (PRASA), 2012)
We present progress towards automated Lecture Transcription (LT) in resource scarce environments. Our development has focused on the transcription of lectures in Afrikaans from two faculties at North-West University. A ...
Modeling drift along the heliospheric wavy neutral sheet
(IOP Publishing, 2012)
Drift along the wavy heliospheric neutral sheet is believed to play an important role in cosmic-ray modulation and can explain the peaked versus flat intensity profiles during consecutive solar magnetic epochs. Modulation ...
ICT to disempower? A perspective on ICT as postmodern agent
(2010)
The wholesale implementation of Information Technology (IT) has brought with it a host of unintended and unforeseen consequences. Through a literature review and an examination of both postmodernism and IT, it is proposed ...
Considerations in Grounded Theory Research Method: A reflection on the lessons learned
(2010)
This paper is a discussion on the practical issues faced by Information Systems (IS) professionals when they employ Grounded Theory Method (GTM) in Information Systems research. Various strands of GTM are in use, all of ...
X-ray and gamma-ray polarization in leptonic and hadronic jet models of blazars
(IOP Science, 2013)
We present a theoretical analysis of the expected X-ray and γ-ray polarization signatures resulting from synchrotron self-Compton emission in leptonic models compared to the polarization signatures from proton synchrotron ...
