Impact of plasma arc reforming deployment on economic performance of a commercial coal to liquids process
(Elsevier, 2017)Coal remains integral to the supply of energy in many parts of the world despite the associated negative effects on the environment. Plasma arc reforming has the potential of making coal to liquids processes cleaner by ... -
Impact of solubilising matrices for TiCl4 on the formation of TiO2 nanoparticles
(EARET, 2018)Several nanoparticles (Cu2O, SnO, ZnO) have been intensively studied and applied in wastewater treatment research, with TiO2 gaining popularity because of its stability, affordability, large band gap, recyclability and ... -
Impact of thermoelectric cooling modules on the efficiency of a single-phase asynchronous machine
(Energy Research Centre, University of Cape Town, 2014)In this paper, the authors present the impact of thermoelectric cooling modules (TECMs) on the efficiency of a single-phase asynchronous machine. TECMs are used to lower the stator winding temperature and core temperature ... -
Impact on power factor by small scale renewable energy generation
(IEEE, 2017)Domestic installations traditionally were believed to be resistive in nature and did not affect power factor much, if at all. With increasing affordability of air-conditioners, and replacement of electrical geysers with ... -
Implementing a business improvement model based on integrated plant information
(Stellenbosch Univ, 2016)The World Energy Council [1, 2] defines numerous challenges in the global energy arena that put pressure on owners and /operators to operate run existing plant better and more efficiently. As such there is an increasing ... -
Implementing a DIKW model on a deep mine cooling system
(Elsevier, 2019)The South African mining industry has been experiencing increasing economic pressure. Deep mines also suffer from very hot workplaces, which leads to safety risks. These factors place stress on managers to reach their ... -
Implementing an optimisation model for turbine investment selection under fluctuating steam productions
(IEEE, 2016)Engineering plants typically have a variety of interlinked production chains, where process flows are dependent on upstream or downstream events. Raw material feeds may fluctuate over time, resulting in fluctuating off-gas ... -
Implication of plants and microbial metalloproteins in the bioremediation of polluted waters: a review
(Elsevier, 2014)Traditional approaches to municipal water monitoring barely includes procedures for toxic heavy metals testing. However, the presence of such contaminants in water sources is expected in South African surface and ground ... -
Implications of Sepedi/English code switching for ASR systems
(Pattern recognition association of South Africa (PRASA), 2013)Code switching (the process of switching from one language to another during a conversation) is a common phenomenon in multilingual environments. Where a minority and dominant language coincide, code switching from the ... -
Improved event based method for harmonic impedance assessment
(IEEE, 2016)The quantification of harmonic emission requires an accurate model of the network harmonic impedances. A number of techniques have been proposed for the assessment of the network harmonic impedances to be practical and ... -
Improved gold recovery by accelerated gravity separation
(Gecamin Publishers, 2014)This project was specifically aimed at using increased acceleration separation, as a method to optimize the recovery of gold in an ore body mainly consisting of hematite where the specific gravity of gold is much higher ... -
Improved reactivity of large coal particles by K2CO3 addition during steam gasification
(Elsevier, 2013)In this study, the excess solution impregnation method was used to impregnate large coal particles (5 and 10 mm) with K2CO3, and the effect of the additive on steam gasification reactivity was investigated. A washed bituminous, ... -
Improved transition models for cepstral trajectories
(Pattern recognition association of South Africa (PRASA), 2012)We improve on a piece-wise linear model of the trajectories of Mel Frequency Cepstral Coefficients, which are commonly used as features in Automatic Speech Recognition. For this purpose, we have created a very clean ... -
The improvement of system damping by grid integration of PV energy sources
(IEEE, 2017)The impact of static generators on power system small signal stability is evaluated by means of micro-synchrophasors collected in a distribution system using a class A Power Quality recorder that also functions as a Phasor ... -
Improving data management for environmental reporting in the gold mining industry
(Stellenbosch Univ, 2019)Environmental reporting is a realistic alternative for mines to prioritise operational changes in crucial environmental areas. Gold mines report to multiple platforms – i.e., integrated reporting. All these platforms ... -
Improving dynamic microgrid modelling through the use of synchronised field data
(IEEE, 2020)Simulation during the design and operation of microgrids should include dynamic phenomena that would be a result of the unpredictable variation in renewable generation and loading. Detailed modelling of different components ... -
Improving energy consumption of an induction motor by design of a power factor correction system and estimation of it's saving on a large scale
(IEEE, 2014)Power factor correction (PFC) is common in commercial and industrial applications. A need to extend its application increased with the dwindling natural resources used for power generation and also exceeding energy demand, ... -
Improving functional density of time-critical applications using hardware-based dynamic reconfiguration and bitstream specialisation
(South African Institute of Computer Scientists and Information Technologists, 2019)The dynamic reconfiguration of an FPGA has many advantages, but the overhead from the process reduces the functional density of applications. Functional density is an indication of the composite benefits a reconfigured ... -
Improving QoS for real-time multimedia traffic in ad-hoc networks with delay aware multi-path routing
(IEEE, 2008)A Mobile Ad-hoc Network (MANET) is a wireless network in which nodes, in the absence of fixed access points, communicate via single or multi-hop paths. Each node in a MANET should thus be able to perform necessary routing ... -
