Induction motor efficiency test methods: a comparison of standards
(IEEE, 2017)
Improved efficiency is the task of the hour. Environmental challenges, which include climate change, global warming and greenhouse gas emission have been fuelling the need to increase energy efficiency in electrical rotating ...
Response Surface Modeling and Optimization to Elucidate the Differential Effects of Demographic Characteristics on HIV Prevalence in South Africa
(IEEE, 2012)
In this study, a Central Composite Face Centered (CCF) design was employed to study the individual and interaction effects of demographic characteristics on the spread of HIV in South Africa. The demographic characteristics ...
Innovative Teaching in Systems Analysis and Design - an Action Research Project
(WASET, 2012)
Systems Analysis and Design is a key subject in Information Technology courses, but students do not find it easy to cope with, since it is not “precise" like programming and not exact like Mathematics. It is a subject ...
A critical social research perspective on self-directed learning and information technology practitioners
(WASET, 2012)
Information systems practitioners are frequently required to master new technology, often without the aid of formal training. They require the skill to manage their own learning and, when this skill is developed in their ...
Critical thinking perspectives on work integrated learning in information systems education
(WASET, 2012)
Students with high level skills are in demand, especially in scare skill environments. If universities wish to be successful and competitive, its students need to be adequately equipped with the necessary tools. Work ...
Multifaceted nanominerals and ultrafine particles in phosphogypsum: a by-product of coal cleaning rejects
(International Pittsburgh Coal Conference, 2016)
Evaluation of a domestic-use low-smoke fuel produced via the pyrolysis of lump coals
(International Pittsburgh Coal Conference, 2016)
The influence of K2CO3 on the swelling and caking behavior of large South African coal particles

Change detection in INARCH time series of counts
(Springer, 2016)
In the present paper we develop an online procedure for detecting changes in the parameters of integer ARCH models of order one. The test statistic utilizes the notion of the empirical probability generating function. The ...
