Energy-based fault detection for an autothermal reformer
(Elsevier, 2016)Condition monitoring has traditionally been deployed for the monitoring of a single component, such as a rotating machine. The application of condition monitoring techniques to entire petrochemical process plants, however, ... -
Energy-based visualisation of a counter-flow heat exchanger for the purpose of fault identification
(Elsevier, 2016)The need for fault detection and diagnosis (FDD) is becoming increasingly important for industrial processes as the complexity of processes increases. A state space model of a counter-flow heat exchanger is used study to ... -
Energy-based visualisation of an axial-flow compressor system for the purposes of fault detection and diagnosis
(Elsevier, 2016)As the complexity of industrial systems increases, the necessity also increases for more reliable, robust and accurate Fault Detection and Diagnosis (FDD) techniques. This article proposes a methodology for the design of ... -
Engineering management and business intelligence: the importance of plant design base
(SAIIE, 2016)Most popular business improvement models center their framework and approaches around business process improvement – thus on people, process and technology aspects of the business. They tend to drive business process ... -
Engineering principles and medical discoveries

Enhancement of bio-methane production by lignocellulose substrates
(ETA-Florence Renewable Energies, 2015)In this study, water hyacinth, sweet sorghum bagasse and amaranth stems were used in a pig manure matrix to produce biogas with a high methane content. The anaerobic digestion was monitored over a period of 40 days, after ... -
Enthalpy-entropy graph approach for the classification of faults in the main power system of a closed Brayton cycle HTGR
(Elsevier, 2009)An enthalpy–entropy (h–s) graph approach for the classification of faults in a new generation type high temperature gas-cooled reactor (HTGR) is presented. The study is performed on a 165 MW model of the main power system ... -
Environmental assessment and nano-mineralogical characterization of coal, overburden and sediment from Indian coal mining acid drainage
(Elsevier, 2017)The deterioration of environmental conditions is the major contributory factor to poor health and quality of life that hinders sustainable development in any region. Coal mining is one of the major industries that contribute ... -
Environmental impact of an industrial compressed air system for solar power in South Africa
(Multi-Science Publishing, 2012)Almost 14% of the electricity generated by the national energy supplier (Eskom) in South Africa is sold directly to the mining sector and almost 20% is utilized directly by the compressed air systems of the mining sector. ... -
Environmental impact of an industrial compressed air system with a solar powered compressor in South Africa
(Sage, 2012)Almost 14% of the electricity generated by the national energy supplier (Eskom) in South Africa is sold directly to the mining sector and almost 20% is utilized directly by the compressed air systems of the mining sector. ... -
Environmental pollution and nano-mineralogical characterization of coal, overburden and sediment from Assam (India) coal mining acid drainage
(International Pittsburgh Coal Conference, 2016) -
Enzymatic biodiesel production from Manilkara Zapota (L.) seed oil
(Springer, 2017)Oil obtained from the seeds of Manilkara zapota (L.) was transesterified with methanol using lipases as biocatalysts. Four commercially available lipases, such as, porcine pancreas, Candida rugosa, Pseudomonas cepacia and ... -
Enzymatic recovery of water from water hyacinth
(ETA-Florence Renewable Energies, 2013)This study sought to assess the viability of utilizing water recovered from a declared aquatic weed, Eichhornia crassipes, commonly known as the water hyacinth, for domestic, industrial and agricultural purposes. Celluclast, ... -
Equilibrium, kinetic, and thermodynamic studies of lead ion adsorption from mine wastewater onto MoS2-clinoptilolite composite
(Elsevier, 2020)This work explored the potential of clinoptilolite, molybdenum sulphide (MoS2), and MoS2-clinoptilolite composite in lead (Pb) removal from aqueous medium and industrial mining wastewater. MoS2-clinoptilolite composite was ... -
Equivalent electrical circuit modelling of a Proton Exchange Membrane electrolyser based on current interruption
(IEEE, 2013)A Proton Exchange Membrane (PEM) electrolyser is characterised and modelled to identify important electrochemical effects. These electrochemical effects include the ohmic, activation, and concentration losses within the ... -
Error correction with the implicit encoding capability of random network coding
(Springer, 2010)In this paper, we present a technique for a network error correcting code using Random Network Coding. We introduce a novel error correction scheme that uses the implicit encoding capability of Random Network Coding. This ... -
Establishing suitable conditions for metals recovery from metal saturated Bacillaceae bacterium using experimental design
(Elsevier, 2014)In this study the response surface methodology (RSM) based on the Box-Behnken design model was applied to investigate the effect of parameter interactions that are suspected to influence the metal desorption process. The ... -
Estimating changes in seismic wave velocity from a pneumatic source in an operational mine
(SEG, 2019)Rock mass characteristics such as applied stress, pore pressure, and fracture density are coupled to the seismic wave propagation velocity. Therefore, measuring small relative changes of seismic wave velocities in operational ... -
