Geometrization

This paper presents the problem of exponential stabilization of switched systems with mixed timevarying delays in state and control. Based on the partitioning of the stability state regions into convex cones, a constructive geometric design for switching laws is put forward.

This study aims to use CFD analysis of CT scan data from the nasal cavities of a range of older Asian males to investigate the impact of geometric variations between older nasal cavities on the airflow structures and airconditioning capacity of the nasal cavity. Air flow mechanisms, heat transfer rates and humidification efficacy are analysed in order to arrive at a more precise understanding of the role of nasal geometry in the presentation of respiratory ailments.

The focus of this thesis was to study the chemotaxonomic relationship of selected southern Australian marine brown algae of the genera Cystophora and Sargassum. Consequently, this resulted in the isolation and structure elucidation of six new terpenoids from two southern Australian marine brown algae Cystophora moniliformis and Sargassum fallax together with 10 previously reported natural products. As a result of the re-isolation of these known secondary metabolites, updated and complete structural characterisation data could be provided for the first time for 7 of these compounds.

The aim of this project "Tessellation: exploring pathways and partitions" is to explore visual pathways within a series of tessellated art works. The term ‘visual pathway’ may in this case extend to include disruption of space and surface, the partitioning of space and surface, as well as the exploration of various pathways that flow through space and surface.

The main aims of this study are to: understand the phenomena of isolated mixing regions (IMRs) in Newtonian fluids agitated in mechanically stirred vessels, in particular, the formation of core torus, using experimental studies; investigate the behavior of IMRs structures by manipulating the operating variables such as impeller rotational speed and direction, as well as geometrical variables such as impeller types and baffle location; investigate the temporal chaotic mixing using different speed modulation protocols.

This thesis derives closed form equations to describe electromagnetic device characteristics for a toroid, solenoid and a case study induction machine. By considering stored magnetic field energy, this approach allows the relationship between electrical, magnetic and kinetic energy to be quantified and analyzed in ways that allows improved accuracy compared with conventional magnetic circuit modeling methods. This thesis also provides insights into how geometric parameters impact energy transfer and operational characteristics of electromagnetic devices.

The current research is undertaken by performing Computational Fluid Dynamics (CFD) simulations for a 2D aerofoil fitted with a shock control bump at a transonic flow condition. Reynolds-Averaged Navier-Stokes equation coupled with turbulence models is adopted to solve the flowfield. The bump has a conventional geometric feature which consists of a ramp, a crest and a tail, and it has eight variants for which the designed parameters are reasonably specified according to the compressible aerodynamics theory.
