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 ... -
Fine coal dewatering using high airflow
(Taylor & Francis, 2014)Fluidized bed drying is currently receiving much attention as a dewatering option after the beneficiation of fine coal. Apart from concerns about safety and combustion, the operating costs can be high if very high gas or ... -
Fingerprint matching on smart card: a review
(IEEE, 2017)Fingerprint Match-on-Card (MoC) offers the highest degree of privacy and security to cardholders as the fingerprint never leaves the secure environment of a smart card. The level of security of a biometric system is evaluated ... -
Finite element density functional calculations for light molecules using a cusp factor to mitigate the Coulomb potential
(Springer, 2019)Finite element calculations have been performed in Cartesian coordinates using the density functional approach for a number of small molecules. In order to aid convergence of the orbitals and total energies a suitable cusp ... -
Finite element density functional calculations for light molecules using a cusp factor to mitigate the Coulomb potential
(EDP Sciences, 2019)Finite element calculations have been performed in Cartesian coordinates using the density functional approach for a number of small molecules. In order to aid convergence of the orbitals and total energies a suitable cusp ... -
Finite element modal analysis for a cooler fan support structure

First principles study of single and multi-site transition metal dopant ions in MoS2 monolayer
(Elsevier, 2019)Using first-principles calculation, a systematic study on the effect of transition metal (TM: V, Cr, Mn, Fe, Co, Ni) dopant atoms in the MoS2 monolayer as potential spintronic, catalytic and optoelectronic materials were ... -
First-principle studies of ferrimagnetic double perovskite Ca2FeMoO6 compound
(Springer, 2019)Using first-principle calculations, the structural, electronic, and magnetic properties of the Ca2FeMoO6 double perovskite compound is investigated. Different spin-ordering: ferrimagnetic (FiM), ferromagnetic (FM), and ... -
Flight controller and low-cost test environment for a simulated helicopter
(IFAC, 2014)In this paper, optimal linear control techniques are utilised to control a radio-controlled helicopter (30 size) in the AeroSIMRC simulation environment. A grey-box time-domain system identification method is used to ... -
Flocculant types and operating conditions influencing particles settling rates in feed water used at a coal power plant
(Desalination Publications, 2019)South Africa is a semi-arid country with an average rainfall less than half of the average rainfall worldwide. From the country limited water resource, 2%–3% of the water is used in energy generation. Thus the water ... -
The flow and heat transfer in a packed bed high temperature gas-cooled reactor
(ASME, 2010)Engineers are faced with two major challenges when carrying out the thermal-fluid design of a complex system consisting of many interacting components such as the PBMR power plant. The first challenge is to predict the ... -
Flow over a glider canopy
(Royal Aeronautical Society, 2014)In order to minimise drag, the front part of most modern glider fuselages is shaped so that laminar flow is preserved to a position close to the wing-to-fuselage junction. Experimental investigations on a full-scale JS1 ... -
Fluidized bed gasification of selected South African coals
(South African Institute of Mining and Metallurgy, 2010) -
A flux splitting method for the Euler equations
(Elsevier, 2014)The solution of the Euler and Navier–Stokes equations was the focus of this research. As with methods such as the AUSM-family, this work further attempted to construct an explicit upwind method that combines both simplicity ... -
Fly ash resistivity profiling for South African coal fired power stations
(David Publishing, 2013)Particulate emission is a major problem in industrial processes, mainly power plants that make use of coal as a primary source of energy. Stringent emissions limits, set by government organisations requires industries to ...
