Neural network models for leukaemia.
(2009)
Artificial neural networks (ANN) can detect complex non-linear relationships between independent and dependent variables. Properly trained ANNs have repeatedly demonstrated superior predictive accuracy to other predictive ...
Real-time observer modelling of a gas-phase ethylene polymerisation reactor.
(2000)
The desire for precise polymer property control, minimum wastage through grade transitions,
and early instrument fault detection, has led to a significant effort in the modelling and control
of ethylene polymerisation ...
Model predictive control of hybrid systems.
(2002)
Hybrid systems combine the continuous behavior evolution specified by differential equations with discontinuous changes specified by discrete event logic. Usually these systems in the processing industry can be identified ...
Inverse internal model control of an ethylene polymerisation reactor using artificial neural networks.
(2001)
An artificial neural network is a mathematical black-box modelling tool. This tool can
be used to model complex non-linear multivariable processes. In attempting to create
an inverse process model of an industrial linear ...
Adaptive dynamic matrix control for a multivariable training plant.
(2001)
Dynamic Matrix Control (DMC) has proven to be a powerful tool for optimal regulation of
chemical processes under constrained conditions. The internal model of this predictive
controller is based on step response measurements ...
A comparative study of contacting equipment for the recovery of copper from cupric sulphate solution.
(2005)
Ion exchange for the recovery of metals from solutions is a well established process. It features significantly in terms of being able to recover valuable substances from what would otherwise be waste streams as well as ...
The anaerobic baffled reactor for sanitation in dense peri-urban settlements.
(2005)
Human consumption of water contaminated with faecal polIutants is the source of most sanitation related diseases. Excreta related diseases can be controlIed by improvements in excreta disposal. The primary consideration ...
Mathematical modelling of climbing film evaporators.
(2001)
Climbing film evaporators are in widespread use in the South African sugar industry, with
the vast majority of the local sugar mills currently utilising these evaporators as first effect
vessels in multiple effect ...
Development amd implementation of a real-time observer model for mineral processing circuits.
(2004)
Mineral processing plan ts, such as LONMIN's Eastern Platinum B-stream, typically have few on-line measurements, and key measures of performance such as grade only become available after samples have been analysed in the ...
An investigation into a lower temperature and low cost direct reduction process for iron-making.
(2003)
The blast furnace process for the reduction of iron ore to pig iron faces problems such as
emission of air pollutants, high investment cost and the current major problem of
decreasing supplies of coke. Coke is used ...
