An integrated knowledge engineering approach to process modelling
Industrial processes can often neither be modelled analytically nor identified experimentally with respect to all their nonlinear properties. For control engineering purposes, real processes are therefore approximated with models of relatively low complexity. Although such approximations are …

Spatial point process modelling of a biodiverse plant community
… addresses the suitability of spatial point processes for the modelling of plant communities with the aim of understanding the mechanisms that sustain biodiversity and allow species coexistence through an analysis of a biodiverse plant community in Western Australia.<br/><br/>Terrestrial …

Predictive Disintegration Process Modelling of Immediate Release Tablets Using Terahertz Technology
In the drug product development process, linking Critical Material Attributes (CMAs) and Critical Process Parameters (CPPs) to Critical Quality Attributes (CQAs) like disintegration performance is essential, particularly during scale-up. Predicting disintegration for immediate-release tablets …

Advanced batch process modelling, control and optimization for injection stretch blow moulding
The injection stretch blow Moulding (ISBM) process is widely used to manufacture PET bottles for the beverage and consumer goods industry. However, at present the ISBM process, including both the stretch blow moulding and reheating processes, are totally open-loop. The processes are complex and …

A Comparison of Wastewater Process Modelling Tools: Case Study of Potsdam WWTW
A wastewater process model can either be based on a steady-state or dynamic mathematical modelling approach. The characterisation of the influent wastewater and specific wastewater parameters are critical input parameters to the mathematical model, whether for design, optimisation or to measure the …

Business process modelling and simulation with application to a start-up actuarial firm
… to model, understand and evaluate the business process at a start-up actuarial firm which employs Report Writers (RWers) who specialise in quantifying actuarial matters. We simulated various "what-if" and extreme scenarios relating to (1) the impact of qualitative variables (stress, morale and …

Point Process Modelling of Objects in the Star Formation Complexes of the M33 Galaxy
In this thesis, Gibbs point process (GPP) models are constructed to study the spatial distribution of objects in the star formation complexes of the M33 galaxy. The GPP models circumvent the limitations of the two-point correlation function employed in the current astronomy literature by naturally …

Dynamic process modelling of the HPS2 solar thermal molten salt parabolic trough test facility
… and there is a need for a dynamic thermofluid process model to better understand and predict both its steady state and transient operational behaviour. This dissertation reports on the development of such a dynamic thermofluid process model and the results obtained from it. The process model …

Development of a process modelling methodology and condition monitoring platform for air-cooled condensers
… ambient conditions. This study focuses on modelling a utility-scale ACC system at steady-state conditions applying a 1-D network modelling approach and using a component-level discretization approach. This approach allowed for each cell to be modelled individually, accounting for steam duct …

Increasing the level of reuse of complete process models in a process modelling repository
Business Process Modeling has become a common activity in organisations. However, as the number of process models increases, so too does the number of duplicated models increase, and the level of process model reuse has been found to be surprisingly low. In organisations which operate in an …

Development and implementation of robust large deformation and contact mechanics capabilities in process modelling of composites
Autoclave processing of large scale, one-piece structural parts made of carbon fiber-reinforced polymer composite materials is the key to decreasing manufacturing costs while at the same time increasing quality. Nonetheless, even in manufacturing simple flat parts, residual strains and stresses are …

Evaluation of three carbon sources for the biological treatment of acid mine drainage through process modelling
… constitute acid mine drainage. This natural process results from the exposure of ores to atmospheric conditions coupled with bacterial activity (Tsukamoto and Miller, 1999). Pollution by AMO can have a devastating effect on terrestrial and aquatic ecosystems. It is a long-term environmental …

A Process Modelling Framework Based on Point Interval Temporal Logic with an Application to Modelling Patient Flows
… including healthcare. Constructing a consistent process model can be instrumental in streamlining healthcare issues. Current process modelling techniques used in healthcare such as flowcharts, unified modelling language activity diagram (UML AD), and business process modelling notation (BPMN) are …

Building Physics Tools: Needs, Use and the Lack of Use in the Building Process. Modelling Non-Isothermal Moisture Flow and Frost Penetration
… already during the design stage of the building process. This thesis looks at some of the costs associated with building failures due to moisture problems and explores the reasons why these failures are persistent in the building industry. This is done by looking at the role of computer based …
