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 ... -
Genetic fuzzy rule extraction for optimised sizing and control of hybrid renewable energy hydrogen systems
(Elsevier, 2020)A major challenge related to the design of a hybrid renewable energy hydrogen system is which energy sources to include and at what capacity, for regionally different potentials of renewable energy and hydrogen demand. In ... -
Geochemical mobility of potential hazardous elements of coal cleaning rejects
(International Pittsburgh Coal Conference, 2016) -
Geochemistry of ultra-fine and nano-compounds in coal gasification ashes: a synoptic view
(Elsevier, 2013)The nano-mineralogy, petrology, and chemistry of coal gasification products have not been studied as extensively as the products of themorewidely used pulverized-coal combustion. The solid residues from the gasification ... -
Geometry based analysis of an alternative RFID interrogator placement for electronic vehicle identification
(IEEE, 2015)This paper proposes a solution for reliable in-traffic electronic vehicle detection based on UHF passive RFID (ISO/IEC 18000-63 - UHF Type C). The classic overhead placement of an interrogator reading a windscreen or plate ... -
The global galerkin finite element method as applied to the 1d beam equation: a systems approach
(SAAM, 2006)The paper focuses on the finite element solution of the fourth-order differential for an EulerBernoulli beam. In this approach the point point loads and concentrated moments are treated in a natural way as part of the ... -
Glycerol-free biodiesel production through transesterification: a review
(Elsevier, 2016)Waste oils are becoming increasingly more important as feedstock for the production of fuels and chemicals. However, the high level of impurities in waste oils limits their use in transesterification reactions where methanol ... -
Graph matching as a means to energy-visualisation of a counter-flow heat exchanger for the purpose of fault diagnosis
(Elsevier, 2017)Energy is a holistic way of analysing multi-domain systems. By using energy, system information can be reduced to essential or dominant dynamics. This could be advantageous for the purpose of fault diagnosis. In this paper, ... -
Green coal development for application in fixed-bed catalytic gasification
(SAIMM, 2018)A novel ‘green coal’ product formulation has recently been developed and the utilization concept tested at the North-West University coal research laboratories. Hydrothermal liquefaction was used to produce bio-oil ... -
Groundwater as an alternative source to irregular surface water in the O'Kiep area, Namaqualand, South Africa
(Elsevier, 2019)Water insecurity is a growing concern globally and the role of groundwater and aquifers in buffering the effects of climate variability and change is increasingly acknowledged due to extended periods of drought in arid ... -
Groundwater monitoring during underground coal gasification
(SAIMM, 2018)Underground coal gasification (UCG) is a fast-emerging, in situ mining technology that provides access to low-cost energy through the utilization of coal reserves that are currently not technically or economically exploitable ... -
Gum ghatti and acrylic acid based biodegradable hydrogels for the effective adsorption of cationic dyes
(Elsevier, 2015)This article reports biosorption properties of Gum ghatti and acrylic acid based graft co-polymers for the adsorption of methylene blue (MB) and rhodamine B (RhB). Gg–cl–PAA removed 99% MB and 98% RhB from the respective ... -
Harmonic emission assessment on a distribution network: the opportunity for the prevailing angle in harmonic phasors
(IET, 2017)Harmonic emission assessment in high-voltage networks with a number of renewable power plants (RPP) interconnected is challenging. A sound scientific methodology readily accessible to engineers is needed to validate ...
