Factors influencing the performance and efficiency of solar water pumping systems: a review
(Academic journals, 2012)The world is having an energy crisis and currently there is a strong drive towards renewable energy. A renewable energy option is solar energy, where by means of photovoltaic (PV) modules electrical energy can be produced. ... -
Factors that affect the accuracy of text-based language identification
(Computer Speech and Language, 2012)We investigate the factors that determine the performance of text-based language identification, with a particular focus on the 11 official languages of South Africa, using n-gram statistics as features for classification. ... -
FACTSAGE™ thermo-equilibrium simulations of mineral transformations in coal combustion ash
(SAIMM, 2018)The aim of this investigation is to report on the influence of operating conditions, and of additives such as potassium carbonate, on the slagging behaviour of South African coal. This was done using a FACTSAGE™ model that ... -
Failure modes in a carbon / titanium fibre metal laminate under hyper-velocity impact
(Elsevier, 2019)Titanium and carbon-fibre reinforced epoxy fibre metal laminates (FMLs) are investigated to determine their potential as a mass efficient passive armour for countering the threat of explosively formed projectiles (EFPs) ... -

Failure prediction of mine compressors
(Springer, 2019)A typical compressed air system on a deep-level mine requires a combination of compressors to supply sufficient energy to critical underground equipment for safe operation. These compressors are required to run continuously ... -
Failure prediction of mine de-watering pumps
(Springer, 2018)The de-watering reticulation system of a deep level mine requires a network of pumps to pump water from underground to the surface. These de-watering pumps are exposed to extreme operating conditions, which can result in ... -
Fault detection and characterisation in pressurised water reactors using real-time simulations
(Elsevier, 2011)The use of real-time plant simulators running in parallel with a nuclear plant to predict the control system behaviour and highlighting unexpected plant behaviour is presented. The study is performed on a 910 MW Generation ... -
Fault detection techniques on active magnetic bearing systems and electrical machines: a review
(SPC, 2018)This paper provides a review on fault detection techniques on active magnetic bearing systems and electrical machines. The following non-linear processing fault detection techniques are discussed in this paper: 1) Time ... -
Fault diagnosis of generation IV nuclear HTGR components. Part 1. The error enthalpy-entropy graph approach
(Elsevier, 2012)Fault diagnosis (FD) is an important element in modern nuclear power plant (NPP) diagnostic systems. In this respect, FD of generation II and III water-cooled nuclear energy systems has become an active research topic to ... -
Fault diagnosis of generation IV nuclear HTGR components. Part 2. The area error enthalpy-entropy graph approach
(Elsevier, 2012)The second paper in a two part series presents the area error method for generation of representative enthalpy–entropy (h–s) fault signatures to classify malfunctions in generation IV nuclear high temperature gas-cooled ... -
Feasibility of cultivating Hartbeespoort Dam microalgae
(ETA-Florence Renewable Energies, 2011)Three cultivation experiments were conducted to grow microalgae in three consecutively scaled-up laboratory systems, which consisted of one, five and 135-litre bioreactors. The highest productivity achieved under optimum ... -
Feasibility of electro-reduction of U(VI) in oxalic acid using an electrolytic CEM-separated cell
(Springer, 2020)The feasibility of electrolytic stripping of U(VI) using an electrolytic separation cell with anode and cathode compartments, separated by a cation exchange membrane (CEM), was investigated as a possible final step in a ... -
A FEM model for microwave absorption and heat transfer in a microwave combination washer dryer
(IEEE, 2013)Applications for the use of microwaves reach far and wide in various industries. Commonly known is the use of microwaves to heat foodstuffs. Research and development conducted in the development of a microwave combination ... -
Fermentation of lignocellulosic biomass using ultrasonic pretreatment
(ETA-Florence Renewable Energies, 2014)The potential fermentation of the sugars derived from water hyacinth, sweet sorghum bagasse and amaranth using indirect ultrasonic pretreatment, was investigated. The optimum sugar and ethanol yield for the ultrasonic bath ... -
Field performance of ambient modal estimation in small signal stability
(IEEE, 2015)Small signal stability is one focus of Wide Area Measurement Systems (WAMS). WAMS systems are becoming more widespread, driven by availability of synchrophasor data from Phasor Measurement Units (PMUs). In this paper, two ... -
Financial analysis of waste-to-energy grate incineration power plant for a small city
(IEEE, 2015)Grate incineration is a widely used waste-to-energy (WtE) technology, which has the potential of contributing significantly to clean energy production and sustainable waste management systems. Various research studies have ... -
Financial model for energy efficiency projects in the mining industry
(Elsevier, 2018)The impact of industrial EE projects have previously been understated by the omission of non-energy benefits (NEBs). As a result, several fruitful projects have not been implemented which could have dire consequences for ... -
Finding the four qualities of intelligent industrial reporting
(Stellenbosch Univ, 2019)Internationally, innovation and technology are driving change through concepts such as ‘Industry 4.0’. However, due to various constraints, South Africa is lagging behind in this transformation. Furthermore, local ...
