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 ... -
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 ... -
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, ... -
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 for resource limited random network coding networks
(IEEE, 2011)Random linear network coding is a practical approach to network coding. It is, however, susceptible to corruption of the message packets due to hostile factors in the network. Error correction can be implemented, but in ... -
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 ... -
Establishment and characterization of a murine HSV-2 model for the evaluation of a novel microbicide
(Elsevier, 2019)Herpes simplex virus −2 (HSV-2) is a serious global epidemic with an estimated 400 million people infected and about 20 million cases reported annually. The prevalence in South Africa is at 31% in females aged 15–29 ... -
Establishment and characterization of allograft and xenograft cancer rodent models
(Elsevier, 2019)To evaluate the efficacy of newly synthesized therapies prior to clinical trials, valid and true cancer models should be used [1]. For modelling cancer in vivo, transplantation of rodent (allograft) and human cancer ... -
Estimates for very high energy gamma rays from globular cluster pulsars
(AIP, 2008)Low‐Mass X‐ray Binaries (LMXRBs), believed to be the progenitors of recycled millisecond pulsars (MSPs), occur abundantly in globular clusters (GCs). GCs are therefore expected to host large numbers of MSPs. This is also ... -
Estimating the concentration of nucleation mode aerosol particles over South Africa using satellite remote sensing measurements
(AIP Publishing, 2013)In this work satellite based observations were used to estimate the concentration of nucleation mode aerosols over South Africa. The nucleation mode aerosols can not be detected directly with satellite instruments since ... -
ETHICAL LEADERSHIP AND WORK ENGAGEMENT. TESTING FOR THE MEDIATING ROLE OF TRUST IN THE LEADER
(IBC, 2021)Despite the growing importance of ethical leadership, many organisations worldwide have witnessed diminishing ethical leadership and trust in management. South Africa is not an exception to unethical practices ... -
Evaluating methods to binarize historic cosmic-ray recordings
(IEEE, 2009)Three adaptive image binarization approaches are evaluated to find the method best suited for the binarization of historic cosmic-ray data. The methods are optimized by fine tuning their parameters and they are then ... -
Evaluating predictors of abnormal stock returns multivariate models
(ACTA Press, 2010)In recent years much research effort has been spent on the development of statistical and neural network techniques to predict abnormal stock returns. Much previous work focused on time series prediction of stock returns, ... -
Evaluating the feasibility of the 12L tax incentive for energy-intensive industries
(Univ Stellenbosch, 2017)Section 12L of the South African Income Tax Act (12L) aims to incentivise businesses to become more energy-efficient. However, claiming this benefit is a complex process that can become difficult, time-consuming, and costly ... -
Evaluation and prediction of slow pyrolysis products derived from coals of different rank
(Elsevier, 2017)When coal is heated slowly (<10 °C/min), as in the Lurgi Fixed Bed Dry Bottom (FBDB) gasification process, products formed in the pyrolysis region of the gasifier include gas liquor, condensable tar, oil and non-condensable ... -
Evaluation of a domestic-use low-smoke fuel produced via the pyrolysis of lump coals
(International Pittsburgh Coal Conference, 2016) -
Evaluation of a facial recognition engines for a surveillance system
(IEEE, 2019)This paper presents the evaluation of a facial recognition system when considered in an operational context for the South African environment. Often, performance measures, such as recognition rate, are considered outside ...
