A clinical engineering decision support system
… to develop an idealized clinical engineering model (ICE) that would satisfy South African technological requirements. An extensive literature survey of the current status of clinical engineering in both developed and developing countries was undertaken to provide input to the synthesis …

Computer simulation studies of dense suspension rheology. Computational studies of model sheared fluids; elucidation, interpretation and description of the observed rheological behaviour of simple colloidal suspensions in the granulo-viscous domain by Non-Equilibrium Particulate Dynamics.
Rheological properties of idealised models which exhibit all the non-Newtonian flow phenomenology commonly seen in dense suspensions are investigated by particulate-dynamics computer-simulations. The objectives of these investigations are: (i) to establish the origins of various aspects of dense …

Far-flung influences on midlatitude weather and climate: The stratospheric pathway
… loss in either strength or sign. A series of idealised model simulations is first used to show that the stratospheric response is sensitive to characteristics of the near-surface Arctic warming and mean state of the vortex. Then, a novel analysis of the stratospheric response with thirteen …

Design and optimisation of a novel magnetic detection scheme for encoded magnetic information carriers.
… can measure. The simulations begin with an idealised model of the detector and particle set, with zero coercivity SAF particles and perfect alignment. The different methods that the detector can be used in are assessed, as well as exploring the possible input geometries. Real-world …

Speech, Sex, and Social Norms
… (Chapter 4). In Chapter 5 I reflect on how our models of speech bear on issues of autonomy and power, manifested in differing roles assigned to ‘uptake’. Each essay is self-contained, but taken together they present a picture of how speech constructs identities and enforces norms, especially …

Dynamical and radiative processes in the Upper Troposphere/Lower Stratosphere
… of the stratosphere on the UTLS region. Model experiments illustrate that the TIL can arise as a result of the dynamics and the wave driving leads to an upwelling structure that results in a TIL. The maximum value and the shape of the TIL peak vary considerable depending on how the …

Causes of the interannual variability of deep convection
… of the surface forcing on convection, using an idealised model. The MIT model is integrated over a square box of size 64km x 64 km x 2km initialised with homogeneous salinity and a linear vertical temperature gradient. The configuration of the model is described and validated. A time-periodic …

Climate change impact on ecosystems of Prince Edward Islands: role of oceanic mesoscale processes
… in between the two islands. On a second hand, an idealised model configuration was designed for the PEIs region to study the mesoscale eddy properties and the physical mechanisms of their formation at the ridge. The Eddy Available Potential Energy revealed a maximum of energy around 800 m depth, …

'You are all my people': building disabled community in Uganda's microentrepreneur economy
… effects produced: the programmes establish an idealised model of newly empowered (post-1995) disabled people as independent and self-sufficient. This advantages an elite group who present the desired financial behaviour, including some members of DWG. Disabled people who do not fit the …

Influence of high latitude anomalies on tropical climate phenomena and global climate
… “Tropical Atlantic Dipole” (TAD). Analysis of model data shows a dipole pattern in the SST, with strong cross-equatorial asymmetry in the surface mixed layer. Below the mixed layer the pattern becomes symmetric, and Kelvin and Rossby wave like adjustment can be seen to occur. However, the …

Dynamically induced uncertainty in stratified turbulent mixing models
… regional scales in the ocean, it is necessary to model small-scale turbulent processes and the way in which they enhance mixing in order to form an accurate picture of the vertical transport of heat, nutrients and anthropogenic pollutants. This applies to parameterisation schemes in coarsely …

Shear flow instabilities in stratified magnetohydrodynamics
… framework, extending the two-dimensional (2D) model from Balmforth (2002) to include a uniform horizontal magnetic field aligned with the direction of flow streaming. Using linear stability analysis, we find that the Kolmogorov flow is unstable to three types of linear instabilities in …
