Reactive power compensation, system and voltage stability of an industrial network with short circuit limiting coupler by Shikoana, Victor

“…A short circuit limiting coupler is designed and the transient and voltage stability studies are performed with a short circuit limiting coupler (SLC) applied at the two 132 kV incoming supply lines from Eskom. The simulations are based 011 solving ordinary loadflow cases augmented with dynamic models of the system elements. …”

Molecular modelling of the Streptococcus pneumoniae serogroup 6 capsular polysaccharide antigens by Mathai, Neann Sarah

“…The 6B saccharide has been included in the early conjugate vaccine (PCV-7), and has shown to elicit protection against the 6B as well as some cross-protection against 6A. 6A has since been included in the latter conjugate vaccines in the hopes of eliciting stronger protection against 6A and 6C. Molecular Dynamics simulations were used to investigate the conformations of oligosaccharides with the aim of elucidating a conformational rationale for why small changes in the carbohydrate primary structure result in variable efficacy. …”

Development and application of the CL&Pol polarisable force field for ionic liquid-based electrolytes by Wilson, Tayla Lee

“…The appeal of ILs for such applications lies in the favourable properties, such as high diffusivity, thermal and electrochemical stability, and low volatility. Molecular dynamics (MD) simulation is a powerful tool for studying the physical properties of liquids; however, whereas traditional solvents are typically well described using classical, fixed-charge force fields (FFs), explicit inclusion of polarisation is essential for accurate description of IL dynamics. …”

Systems modelling of the South African offshore demersal hake trawl fishery : an economic perspective by Cooper, Rachel

“…In order to address this need, this study's aims are to i) analyse the structure and dynamics of the economics of the South African offshore demersal hake trawl fishery from empirical data and stakeholder interviews, and ii) produce a prototype economic simulation model of this fishery to better understand the dynamics of the industry and the relative importance of its internal and external drivers, e.g. industrial organization, environmental uncertainty, exchange rate and fuel price. …”

Regime changes in monetary policy by Addo, Samuel

“…The results suggest that an unexpected monetary policy shock and its variances account for a smaller proportion of macroeconomic fluctuations in the South African economy compared to external shocks and its variances in the form of exports, import cost inflation, risk premia, preference and technology changes. Chapter five consists of an investigation into central bank credibility by simulating a Markov-switching Bayesian vector autoregression model with time-varying transition probabilities. …”

A granular flow model of an annular shear cell by Bremner, Sherry

“…The key ingredients (velocity, shear rate and volume fraction distributions) to the granular ow model are extracted from experiments using Positron Emission Particle Tracking (PEPT), as well as Discrete Element Method (DEM) simulations. 5mm glass beads were used to fill an annulus 51mm wide. …”
