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 ... -
Four novel methods for the harvesting of micro-algal biomass
(ETA-Florence Renewable Energies, 2011)The harvesting of micro-algal biomass is one of the most inefficient and costly steps in the whole biomass-to-liquids (BtL) value chain. Harvesting costs may contribute between 20–30% of the total cost of microalgal BtL ... -
Framework for effective additive manufacturing education: a case study of South African universities
(Emerald, 2019)Purpose In this era of Fourth Industrial Revolution, also known as Industry 4.0, additive manufacturing (AM) has been recognized as one of the nine technologies of Industry 4.0 that will revolutionize different sectors ... -
Frequency dependent impedance model for heteropolar magnetic bearings
(Elsevier, 2015)Accurate analytical models are fundamental to design and optimise high performance magnetic bearings. Understanding the bearing’s dynamic behaviour over its operational envelope is essential to this task and is performed ... -
Fuel allocation and lockout system
(IEEE, 2018)In transport and Logistics business with the fierce competition, avoiding fuel theft through monitoring and management is a major concern in Africa. With the steadily increase in fuel price, fuel theft and fraud poses a ... -
Fuel ethanol production from sweet sorghum bagasse using microwave irradiation
(ETA-Florence Renewable Energies, 2013)Sweet sorghum is a hardy crop that can be grown on marginal land and can provide both food and energy in an integrated food and energy system. Lignocellulose rich sweet sorghum bagasse (solid left over after starch and ... -
Fuel not food: towards sustainable utilization of gutter oil
(Taylor & Francis, 2017)Waste cooking oil is discarded into sewage and waste bins in various developing countries. In China, the discarded oil is scooped illegally from drains by smugglers. After collection, the obtained waste oil is reprocessed; ... -
Fullerene functionalised fullerenes aggregates on surface soils and river sediments from Santa Catarina coal mining area
(Swanson School of Engineering, Univ of Pittsburgh, 2015) -
A fully integrated 3D CFD model of the flow and heat transfer in a packed bed reactor
(ANS (American Nuclear Society), 2016) -
Functionalising lignin in crude glycerol to prepare polyols and polyurethane
(Sage, 2019)In this work, crude glycerol liquefaction of lignins produced in the pulp and paper industry, as well as an organosolv lignin (sugarcane bagasse), was studied with the ultimate aim of preparing biobased polyols for ... -
Further development of methodology to model TRISO fuel and BISO absorber particles and related uncertainty quantification using SCALE 6
(Taylor & Francis, 2019)In the 350 MW Modular High Temperature Gas-Cooled Reactor (MHTGR-350), not only is the fuel double heterogeneous but so are the lumped burnable poisons (LBPs). The LBPs are composed of Bi-Structural Isotropic (BISO) particles ... -
Fuzzy logic controller with neurol network signal predictors for complex split-range control of a hybrid actuator
(Elsevier, 2013)This paper presents an integrated fuzzy logic controller (FLC) to address challenges associated with complex split-range control of a two-valves-in-parallel hybrid actuator. Split-range hybrid valve (HV) control aims to ... -
G2P variant prediction techniques for ASR and STD
(Interspeech 2013, 2013)Introducing pronunciation variants into a lexicon is a balancing act: incorporating necessary variants can improve automatic speech recognition (ASR) and spoken term detection (STD) performance by capturing some of the ... -
Gamifying the industrial engineering profession
(IEOM, 2017)An age-old problem facing higher education institutes is the verification that the knowledge taught in class was actually learnt and internalized. Many consider that the quality of education is to be measured on this basis. ... -
Gas crossover mitigation in PEM water electrolysis: hydrogen cross-over benchmark study of 3M's Ir-NSTF based electrolysis catalyst-coated membranes
(ECS, 2016)In this work we present some preliminary data, such as permeability (gas crossover) of oxygen and hydrogen as a function of current density and other operational variables, aimed at establishing baselines for unmitigated ... -
Generating fundamental frequency contours for speech synthesis in Yorùbá
(International Speech Communication Association ( ISCA ), 2013)We present methods for modelling and synthesising fundamental frequency (F0) contours suitable for application in text-to-speech (TTS) synthesis of Yorùbá (an African tone language). These methods are discussed and compared ... -
Generation of ozone and hydrogen in a PEM electrolyzer

A generic method for automatic translation between input models fordifferent versions of simulation codes
(Elsevier, 2014)A computer code was developed for the semi-automatic translation of input models for the VSOP-A diffusion neutronics simulation code to the format of the newer VSOP 99/05 code. In this paper, this algorithm is presented ... -
Genetic algorithm based PID tuning for optimal power control of a three-shaft Brayton cycle based power conversion unit
(Elsevier, 2012)This paper considers the development of a PID control strategy to optimally control the power output of a High Temperature Gas-cooled Reactor (HTGR) power plant. A specific type of HTGR called the Pebble Bed Modular Reactor ...
