Computational modelling of hydrogel therapies by Ahmed, Sadman Sakib

“…A methodology is presented for characterizing the gelation of PEG from existing rheology data. A material model is developed for gelation by using a time-dependent viscosity model that is implemented numerically in Ansys Polyflow. …”

Stochastic models in experimental economics by Monroe, Brian Albert

“…These vary from developing new theoretical models, models that nest EUT as a special case, such as Rank Dependent Utility (RDU) and Regret Theory, as well as models that do not nest EUT, such as Cumulative Prospect Theory, to critiques of experimental methods and scope, to the promotion of stochastic models of choice. …”

Risk-return portfolio modelling by Gilbert, Emmeleen Ulita

“…The Troskie-Hossain innovation to the Sharpe Index model relaxes this assumption. We evaluate the Troskie-Hossain model relative to the Sharpe Index Model and Markowitz portfolio, and find that the Troskie-Hossain model approximates the Markowitz efficient frontier and optimal portfolio very closely. …”

Developments in anaerobic digestion modelling by Ghoor, Tasneem

“…Without adequate modelling of AD dynamics, the AD model cannot be used to model digester start-up, digester failure or even upflow anaerobic sludge bed (UASB) reactors (which have temporary failure conditions at the bottom of the bed). …”

Modelling hepatotoxicity in HIV/TB co-infected patients: extensions of the Cox Proportional Hazards Model by Mlotshwa, Vintia Philile

“…Since the Cox regression model utilized data up to the first occurrence of hepatotoxicity, in some instances, the time-varying treatment effect based on the Cox regression model was closer to unity and marginally significant. …”

Determining appropriate loss coefficients for use in the nozzle-model of a stage-by-stage turbine model by Marx, Alton Cadle

“…This stage-by-stage turbine nozzlemodel component was derived from the synthesis of classical turbine theory and classical nozzle theory enabling the component to accurately model a turbine stage. Utilizing Flownex, a thermohydraulic network solver, the turbine stage component can be expanded to accurately model any arrangement and category of turbine. …”

The Cape Town Violence and Injury Observatory (VIO) Validity and utility of data sources for a prevention-oriented VIO in urban Cape Town, South Africa by Jabar, Ardil

“…The specific objectives of each study component were as follows: • To describe the objectives of the pilot VIO, potential violence-related datasets for collection, data analysis and research dissemination plan (Study One) • To assess the validity and utility of VIOs in reducing violence and violencerelated harms in adult populations (Study Two) • To identify the optimal data elements for inclusion in a VIO according to expert consensus (Study Three) • To determine the concordance between violent crimes reported to the police with violence-related injuries presenting at health facilities in Khayelitsha (Study Four). …”
