Design and cost analysis of an automation system for swimming pools
(EE Publishers, 2012)A low-cost automation system to minimise energy consumption of circulation pumps and to regulate the chemical composition of the water in swimming pools -
The design and development of a stented tissue mitral and aortic heart valve replacement for human implantation
(Clinics Cardive, 2012)A study was conducted into the development of a mitral and aortic heart valve replacement that caters for patients having suffered valve damage due to stenosis or rheumatic fever. The appeal of the valve is that it is ... -
Design and heat flow analysis of a commercial energy efficient in-line water heating system
(Emerald, 2014)In this paper, the authors provide the design, heat flow analysis and pressure analysis of a commercial energy efficient in-line water heating system in South Africa. The designed commercial in-line water heating system ... -
Design and operation of an ammonia-fueled microchannel reactor for autothermal hydrogen production
(Elsevier, 2018)The present work describes the design and operation of an autothermal microchannel reactor for portable and distributed hydrogen production via ammonia decomposition. The microreactor consists of an array of alternating ... -
Design and optimisation of a PCB eddy current displacement sensor
(SAIEE, 2017)Position sensing is one of the crucial parts of many systems, specifically in an active magnetic bearing. The position is used to control the magnetic forces within an active magnetic bearing to keep a rotor levitated. ... -
Design considerations of the PM transverse flux linear motor for an urban-type electromagnetic train
(IEEE, 2018)This paper presents six different designs of the permanent magnet transverse-flux linear motor applied to an electromagnetic train. The initial design of the motor was modified to improve its magnetic characteristics. ... -
Design of a prototype power line inspection robot
(2013)The purpose of this paper is to provide the design of a prototype power line inspection robot for the monitoring of Eskom transmission lines. It should also determine if an inspection robot would be a feasible solution ... -
Design of a prototype ultra-capacitor solar panel street light
(2013)The purpose of the paper is to describe and discuss the design of a prototype ultracapacitor solar panel street light. The effect of ultra-capacitors as an energy storage device in a solar panel street light is evaluated. ... -
Design of a transmission line monitoring solution for an unmanned quadcopter
(2014)Eskom owns thousands of kilometres of transmission lines that need to be inspected in order to plan maintenance. Current methods of inspection are costly and ineffective and could pose safety risks. Systems already developed ... -
Design of an intelligent controller for a renewable energy efficient bulk storage tank
(2015)The national electricity supplier in South Africa is experiencing difficulty in providing the required electricity, due to compliance with environmental regulations and the continuous price increase of commercial fuels. ... -
Design optimization of a line-start PMSM considering transient and steady-state performance objectives
(IEEE, 2017)This paper investigates the use of the Taguchi method based regression rate optimization method for the design of line-start permanent magnet motors. A weighted factor multi-objective (MO) technique is used to take into ... -
Design procedure of a line-start permanent magnet synchronous machine
(SAUPEC, 2014)This paper presents a method for designing an LS-PMSM by dividing the design into sub-machine components. Each of the individual sub-machine components is then designed using several classical machine design principles. ... -
Designing a new methodology for customs risk models
(CCES, 2019)Effective risk management is a prerequisite to find an acceptable balance between the objectives of a customs operation and the streamlined flow of goods. The customs operations in many developing countries are characterised ... -
Destabilization dynamics of clay and acid-free polymers of ferric and magnesium salts in AMD without pH adjustment
(IWA Publishing, 2016)The physicochemical treatment was employed to treat acid mine drainage (AMD) in the removal of turbid materials using clay only (exp A) and a combination of clay, FeCl3 and Mg(OH)2 (exp B) to form a polymer. A 5 g sample ... -
Destoning of fine coal in a fluidized bed
(Springer, 2016)Water scarcity is driving the development of dry coal beneficiation processes. A lot of research has gone into the development of dry dense medium fluidized bed technology (DMFB), especially in China. However, these processes ... -
Detailed characteristics of coal ash from the largest coal-fired power plant in South America

Detailed characterization of SA high mineral matter inertinite–rich coals and density fractions and effect on reaction rates with carbon dioxide: macerals, microlithotypes, carbominerites and minerals
(SAIChE, 2013)An investigation was undertaken to determine the distribution of macerals and minerals in South African Highveld coal deposits as well as density fractions derived from a typical deposit. The corresponding effects on ... -
Determination and the no-free-lunch paradox
(MIT Press, 2011)We discuss the no-free-lunch NFL theorem for supervised learning as a logical paradox—that is, as a counterintuitive result that is correctly proven from apparently incontestable assumptions. We show that the uniform prior ... -
Determination of mineral matter and elemental composition of individual macerals in coals from Highveld mines
(SAIMM, 2016)A number of conventional and advanced analytical techniques (proximate and ultimate analysis, low-temperature oxygen-plasma ashing, X-ray diffraction, X-ray fluorescence spectrometry, coal petrography, and light-element ... -
