Analysis and modelling of mining induced seismicity
(Stellenbosch : University of Stellenbosch, 2006-12)
Earthquakes and other seismic events are known to have catastrophic effects on
people and property. These large-scale events are almost always preceded by smallerscale
seismic events called precursors, such as tremors ...
Non-linear neurocontrol of chemical processes using reinforcement learning
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: The difficulties of chemical process control using plain Proportional-Integral-
Derivative (PID) methods include interaction of process manipulated- and control
variables as well as difficulty in tuning. ...
Improved feed utilisation in cage aquaculture by use of machine vision
(Stellenbosch : Stellenbosch University, 2008-12)
With the harvesting of fish and other aquatic organisms from natural
waters having reached its upper limit, aquaculture is vital in providing for
the ever increasing demand for fishery products (Boyd, 1999). Not
surprisingly, ...
Image texture analysis for inferential sensing in the process industries
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: The measurement of key process quality variables is important for the efficient and economical operation of many chemical and mineral processing systems, as these variables can be used in process monitoring ...
The use of classification methods for gross error detection in process data
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: All process measurements contain some element of error. Typically, a distinction is made between
random errors, with zero expected value, and gross errors with non-zero magnitude. Data Reconciliation
(DR) ...
Acoustic monitoring of DC placma arcs
(Stellenbosch : Stellenbosch University, 2008-03)
ENGLISH ABSTRACT: The arc, generated between the cathode and slag in a dc electric arc furnace
(EAF), constitutes the principal source of thermal energy in the furnace.
Steady state melting conditions rely on efficient ...
Simulation of a palladium extraction circuit
(Stellenbosch : University of Stellenbosch, 2006-12)
ENGLISH ABSTRACT: Behaviour of palladium, platinum, copper, chloride anions, hydrogen cations, the l3-hydroxyoxime LIX 84-1 and the primary amine Primene JM-T during the extraction of Pd at the Anglo Platinum Precious ...
A process performance monitoring methodology for mineral processing plants
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Key to remaining competitive within the mineral industry is ensuring that all processes are always being operated optimally. Process performance monitoring is an ideal initiative with which to accomplish ...
