(University of Pretoria, 2008-09-23)Iron ore sinter is produced from fine-grained ore in order to provide a direct charge to the blast furnace. During the sinter production process fine sinter is produced that is not acceptable as feedstock for the blast ...
-
(University of Pretoria, 2011)The ionosphere is a layer of ionised gas in the upper layers of the atmosphere around the Earth that plays a critical role in satellite communication, military communication and space science. The influence that the ...
-
(University of Pretoria, 2016)The track stitching problem can be divided into two tasks, namely target tracking to create track fragments, and track stitching to stitch the resulting track fragments together. In this study a tracking algorithm is ...

(University of Pretoria, 2014)In this study, a method is developed for modelling and classifying behaviour of maritime vessels in a piracy situation. Prior knowledge is used to construct a probabilistic graphical model of maritime vessel behaviour. ...
-
(University of Pretoria, 2016)Condition monitoring is very important for critical assets such as gearboxes used in the power and mining industries. Fluctuating operating conditions are inevitable for wind turbines and mining machines such as bucket ...
-
(University of Pretoria, 2013)The Anglo American Platinum Converter Plant produces a copper-nickel sulphide converter matte which is slow-cooled in ingots over several days. During the process, the formation of alloy platelets, containing the majority ...
-
(University of Pretoria, 2010-08-25)This experimental work aims to characterize the SiC layer of various Tri-Structural Isotropic (TRISO) coated fuel particles. In the first part of the work, Raman spectroscopy is used to qualitatively characterize the SiC ...
-
GPGPU-accelerated nonlinear state estimators : application to MPC-controlled bioreactor performance (University of Pretoria, 2021)Practical control problems are subject to dealing with instrumentation noise and inaccurate models. These can be modelled as measurement and state noise, respectively. Nonlinear state estimators, for example a particle ...
-
(University of Pretoria, 2017)South Africa is currently struggling to deal with a significant poaching and livestock theft problem. This work is concerned with the detection and classification of ground based targets using radar micro- Doppler signatures ...
-
(University of Pretoria, 2012)High temperature gas cooled nuclear reactors often make use of Tristructural Isotropic (TRISO) coated fuel particles. In these particles, a layer of silicon carbide plays the key role of providing mechanical strength and ...
-
(University of Pretoria, 2021)Since the popularisation of media streaming, a number of video streaming services are continually buying new video content to mine the potential profit. As such, newly added content has to be handled appropriately to be ...
-
(University of Pretoria, 2013)Advances in machine condition monitoring technologies are driven by the rise in complexity of modern machines and the increased demand for product reliability. Condition monitoring research tends to focus on the development ...
-
(University of Pretoria, 2009-10-02)Pyrrhotite (Fe(1-x)S) is one of the most commonly occurring metal sulfide minerals and is recognised in a variety of types of ore deposits. Since the principal nickel ore mineral, pentlandite, almost ubiquitously occurs ...
-
(University of Pretoria, 2019)Deleterious recessive monogenic autosomal conditions are modelled both on an individual level, for diagnostic purposes, as well as in large populations, where the establishment, dispersion and equilibrium behaviour is ...
-
(University of Pretoria, 2013)In high range-resolution (HRR) radar systems, the returns from a single target may fall in multiple adjacent range bins which individually vary in amplitude. A target following this representation is commonly referred ...
-
(University of Pretoria, 2018)In this study, the proliferation of adipose-derived stromal cells was modelled and compared to experimental measurements. The fundamental characteristics of contact-inhibited proliferation were investigated by implementing ...
-
(University of Pretoria, 2017)Approximately three rhinos are poached daily in South Africa. Rhino poaching is a serious problem that a ects not only the rhino population of South Africa, but also the rhino population of the world. South Africa has ...
-
(University of Pretoria, 2019)In this dissertation a combination of numerical and statistical methods are used to analyse and model periodic breaking ocean wave radar data in a littoral coastal zone. Analysis, based primarily on post-aligned parallel ...
-
(University of Pretoria, 2018)Liquidity risk is one of the key risks faced by banks in their daily operations. Following the recent financial crisis, more stringent measures have been put in place to ensure that banks adequately cater for sufficient ...
