On-line analysis of the stability and other features of froths and foams by use of digital image processing
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: The objective of this study is the assessment of the usefulness of an industrial
machine vision system for laboratory studies of especially flotation froths and other
foams. With this in mind it was ...
A neurocontrol paradigm for intelligent process control using evolutionary reinforcement learning
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: A Neurocontrol Paradigm for Intelligent Process Control using Evolutionary
Reinforcement Learning
Balancing multiple business and operational objectives within a comprehensive
control strategy is a ...
Study of the plasma based production of tetrafluoroethylene
(Stellenbosch : Stellenbosch University, 1999-06)
ENGLISH ABSTRACT: A method was developed at the Atomic Energy Corporation of South Africa (AEC) for the
plasma based production of tetrafluoroethylene (TFE). The process involves the feeding of
carbon particles into a ...
Process optimization for partial oxidation of bacterial sludge in a sonochemical reactor
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: It was found that bacterial sludge from anaerobic water treatment systems is produced internationally at a rate of 60 grams per person per day and the accumulation of the potentially hazardous by-product ...
Estimating particle size of hydrocyclone underflow discharge using image analysis
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Hydrocyclones are stationary separating machines that separate materials based on centrifugal separation and are widely used in chemical engineering and mineral processing industries. Their design and ...
Process monitoring with restricted Boltzmann machines
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Process monitoring and fault diagnosis are used to detect abnormal events in processes. The early detection of such events or faults is crucial to continuous process improvement. Although principal component ...
Organic acids as potential growth promoters in abalone culture
(Stellenbosch : Stellenbosch University, 2007-12)
ENGLISH ABSTRACT: The first successful captive spawning of the South African abalone Haliotis midae occurred in
the 1980’s and subsequently the commercial abalone industry in South Africa has
developed, with an estimated ...
Detecting change in complex process systems with phase space methods
(Stellenbosch : University of Stellenbosch, 2006-12)
Model predictive control has become a standard for most control strategies in modern
process plants. It relies heavily on process models, which might not always be
fundamentally available, but can be obtained from time ...
Removal of organic foulants from capillary ultrafiltration membranes by use of ultrasound.
(Stellenbosch : University of Stellenbosch, 2006-03)
Fouling is a serious problem in membrane filtration, caused by pore plugging and
adsorption of rejected macromolecules or other solutes in the membrane system.
This requires periodic cleaning of membranes, which can add ...
On-line monitoring of base metals solutions in flotation using diffuse reflectance spectrophotometry
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: This work evaluates the use of inverse least squares (ILS) and classical least squares (CLS) models for calibration of a diffuse reflectance spectrophotometer for on-line monitoring of the aqueous phase ...
