Analysis of the post-earnings announcement drift anomaly on the JSE
(Taylor & Francis, 2013)
The post-earnings announcement drift anomaly has been widely researched and confirmed for several markets around the world. This paper investigates the relationship between the earnings surprise as reflected by the price ...
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 ...
Intelligente beheer van ’n hernubare, energiedoeltreffende tenk vir melkboerderye
(AOSIS, 2015)
To reduce strain on Eskom and decrease the cost for producing dairy products, an energy-efficient
bulk storage tank using solar power was designed. The system uses thermoelectric cooling
modules as a supporting cooling ...
The Spoken Web Search task at Mediaeval 2012
(Acoustics, Speech and Signal Processing (ICASSP), 2013 IEEE International Conference on, 2013)
In this paper, we describe the “Spoken Web Search” Task, which
was held as part of the 2012 MediaEval benchmark evaluation campaign.
The purpose of this task was to perform audio search with audio
input in four languages, ...
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 ...
Prototype line crawler for power line inspection
(David Publishing, 2013)
In South Africa, electricity is supplied through thousands-of-kilometers of overhead power cables, which is owned by
Eskom the national energy supplier. Currently monitoring of these overhead power cables are done by means ...
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 ...
Dataset on the carbon dioxide, methane and nitrogen high-pressure sorption properties of South African bituminous coals
(Elsevier, 2019)
The dataset presented in this article supplements the result and information published in the report “The carbon dioxide, methane and nitrogen high-pressure sorption properties of South African bituminous coals” (Okolo et ...
Investigation and efficiency analysis: 405 km transmission line with series compensation
(Crown Publications, 2012)
This article presents an investigative case study and efficiency analysis of the 405 km, 420 kV transmission line between Insukamini substation
in Bulawayo, Zimbabwe and the Matimba thermal power station in South Africa ...
