Neurocontroller development for nonlinear processes utilising evolutionary reinforcement learning
(Stellenbosch : Stellenbosch University, 2000-04)
ENGLISH ABSTRACT: The growth in intelligent control has primarily been a reaction to the realisation that
nonlinear control theory has been unable to provide practical solutions to present day
control challenges. ...
The adsorption characteristics of precious and base metals on four different ion-exchange resins
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: Adsorption tests were conducted with four different ion-exchange resins to determine
the equilibrium adsorption of a range of precious and base metals. The adsorption
characteristics were determined ...
The bio-disposal of lignocellulose substances with activated sludge
(Stellenbosch : Stellenbosch University, 2001-03)
ENGLISH ABSTRACT: Lignocellulose is the principal form of biomass in the biosphere and therefore the predominant
renewable source in the environment. However, owing to the chemical and structural
complexity of lignocellulose ...
An experimental study of slag foaming
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: Slag foaming occurs in several pyrometallurgical processes. These processes include
steelmaking in basic oxygen steelmaking furnaces and electric arc furnaces (EAF) as well
as various non-ferrous ...
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 ...
Monitoring of froth systems using principal component analysis
(Stellenbosch : Stellenbosch University, 2002-04)
ENGLISH ABSTRACT: Flotation is notorious for its susceptibility to process upsets and consequently its poor
performance, making successful flotation control systems an elusive goal. The control of
industrial flotation ...
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 ...
Modelling and control of an autogenous mill using a state space methodology and neural networks
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: Metallurgical processes are often high dimensional and non-linear making them
difficult to understand, model and control. Whereas the human eye has extensively
been used in discerning temporal patterns ...
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 ...
