Robust torque ripple mitigation of a line-start PMSM by means of the Taguchi method
(IEEE, 2019)
—In this paper, a robust design framework is proposed
to mitigate torque ripple for line-start permanent magnet synchronous machines (LS-PMSM) by using the Taguchi method.
The framework is intended for fine-tuning initial ...
Comparative study of steam vs hot water as primary heat transfer medium for a laboratory scale two-tank heated system
(IEEE, 2019)
The need exists for a benchmark multi-domain practical system that could emulate typical process faults for the purposes of condition monitoring. A proposition was made to develop a heated two-tank system, due to its ...
Modeling the pulse profiles of millisecond pulsars in the second LAT catalog of γ-ray pulsars
(AIP, 2012)
Significant γ-ray pulsations have been detected from ∼40 millisecond pulsars (MSPs) using 3 years of sky-survey data from the Fermi LAT and radio timing solutions from across the globe. We have fit the radio and γ-ray pulse ...
CREAK descriptor evaluation for visual odometry
(IEEE, 2019)
Each year, latest state of the art technologies and algorithms arise that claim and prove to-shine their predecessors. One such algorithm is the Colour-based Retina Key-point (CREAK) descriptor, which is based on the FAST ...
Evidence-informed decision making for nutrition: African experiences and way forward
(Cambridge Univ Press, 2017)
Although substantial amount of nutrition research is conducted in Africa, the research agenda is mainly donor-driven. There is a clear need for a revised research agenda in Africa which is both driven by and responding to ...
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 ...
An ontology-driven software development framework
(2010)
The software development process has been curtailed by the lack of a methodology that can capture and maintain the softer, humanist characteristics of organizational systems into the software product.
This is attributed ...
A mathematical ranking model in learning analytics
(CMMSE, 2016)
The introduction of new educationa
l trends triggers the development
of innovative methods to collect, analyse and report the data
subsequently generated. This paper
discusses the implementation of a ...
Efficiency analysis of an induction motor with direct torque and flux control at a hot rolling mill
(Energy Research Centre, University of Cape Town, 2015)
This paper presents an efficiency analysis of an
induction motor with direct torque and flux control
at a hot rolling mill in South Africa. Two scenarios
were evaluated: 1) where the induction motor was
controlled at ...
Ontology goes postmodern in ICT
(ACM Press, 2010)
This paper investigates the move from philosophical ontology to information systems ontologies. Ontology has traditionally been (and still is) a philosophical discipline that studies the nature of existence. In a certain ...
