Gas turbines bend when the are turned off, due to differential cooling. This thermal bow can damage the engines if they are restarted too early, which will reduce their fatigue life and can ultimately destroy them in flight. It is therefore crucial to the safe operation of current and future engines that we improve our abilities to predict this bow and design it out.

Scholarships of $35,000 (AUD) are available for PhD students who have achieved Honours 1/High Distinction in their UG program and/or have completed a Masters by Research.
Nerve function can be impaired by localised compression of the nerve fibres due to injury or proximal tumour growth. This project will continue our work to develop and implement numerical and experimental techniques to predict the causes and extent of this damage. In particular it will use nonlinear, multi-scale, finite element models to investigate a range of nerve dysfunctions including bitemporal hemianopia and investigate experimental in-vitro techniques to validate these simulations.
With the spread of IoT devices, security issues are becoming more severe, in part because of the large scale and heterogeneous nature of the devices.
There are an increasing number of insecure IoT devices with a high computational power, this makes them attractive targets for botnet creators.
Compromised IoT devices can be aggregated together through command and control servers to perform a diverse set of activities including; distributed denial of service, password cracking, and crypto-currency mining.
The field of earth observation (EO), or remote sensing, is now facing significant challenges in the processing of image data for end user purposes because of the rapidly escalating numbers of missions and sensors, and because of the range of different types of sensor being orbited.
Variations in solar radiation and solar wind result in variations in the coupled magnetosphere-ionosphere-thermosphere (MIT) system which are referred to as space weather. Changes to this system have several important effects on space and ground based technology; including effects on satellite electronics, satellite orbits, radio signal propagation, and electricity grids. The ability to forecast the effects of space weather events on the MIT system is therefore of great importance to human society.
Flight at extreme speeds challenges the very best of our engineering abilities. The structures of high-speed vehicles are subjected to fluid-thermal-structural interactions in which the deformation of the structure, induced by the aerothermodynamic loads, can in turn influence this flow field and this coupling can detrimentally deform and even catastrophically damage the vehicle. The ability to develop efficient and economical high-speed aircraft is thus limited by our current capabilities in simulating and predicting these complex interactions.
We have developed methods to free fly highly-instrumented, scaled models at hypersonic conditions in wind tunnels to determine their aerodynamic performance. This project will extend that work to fly multiple bodies, in close proximity, to examine a range of phenomena including stage separations and stores release, as well as the reentry break up of satellites and meteorites.
