First realistic modelling of the effects of Ultra Low Frequency (ULF) wave energy in the ionosphere over the Australian region. Ultra Low Frequency (ULF) wave activity is known to produce perturbations of the ionosphere electron density. This affects technologies that involve High Frequency (HF) propagation in the ionosphere such as over-the-horizon radar (OTHR) and radio astronomy. Australia relies on OTHR for surveillance beyond our coastline using the Jindalee Operational Radar Network.

Ultra Low Frequency (ULF) wave activity is known to produce perturbations of the ionosphere electron density. This affects technologies that involve High Frequency (HF) propagation in the ionosphere such as over-the-horizon radar (OTHR) and radio astronomy. Australia relies on OTHR for surveillance beyond our coastline using the Jindalee Operational Radar Network. Australia is also in competition for the next generation radio telescope (the SKA). This project will develop a world first model that combines ULF and HF physics to provide advanced understanding of the generation processes of radar Doppler clutter and differential phase errors in radio astronomy interferometer telescopes.Read moreRead less
Testing a Multi-level Theory of Emotion in Organisations. Affective moods and emotions at work are now recognised internationally as important determinants of employee attitudes and behaviours at work, including job satisfaction, turnover, and performance. This collaborative project involves research teams in Australia and the United States, and entails three studies of the role of emotions in organisations. Based on experience-sampling methods, where participants report real-time data using ha ....Testing a Multi-level Theory of Emotion in Organisations. Affective moods and emotions at work are now recognised internationally as important determinants of employee attitudes and behaviours at work, including job satisfaction, turnover, and performance. This collaborative project involves research teams in Australia and the United States, and entails three studies of the role of emotions in organisations. Based on experience-sampling methods, where participants report real-time data using hand-held computers, the studies span within-person, between-persons, leadership, group, and organisational levels of analysis. The project also extends previous research by studying organisations as a source of depletion of regulatory resources that limit employees' potential to perform to their ability.Read moreRead less
Dynamic Simulation of Gear and Bearing Interactions in Gearboxes for Improved Diagnostics and Prognostics of Faults. The techniques to be developed in this project should become the international standard for diagnostic and prognostic techniques for high speed gearboxes, and improve the performance of Australian industry. Australia being a major supplier of natural resources, with many mines in remote locations, it is heavily dependent on machine condition monitoring techniques, such as those be ....Dynamic Simulation of Gear and Bearing Interactions in Gearboxes for Improved Diagnostics and Prognostics of Faults. The techniques to be developed in this project should become the international standard for diagnostic and prognostic techniques for high speed gearboxes, and improve the performance of Australian industry. Australia being a major supplier of natural resources, with many mines in remote locations, it is heavily dependent on machine condition monitoring techniques, such as those being developed in the project, to maximise output and minimise the likelihood of catastrophic failure. The techniques also give improved safety, for example of helicopters, which are suspended from the gearbox, making it a very critical component. This will be of considerable benefit to both civil and military operators of helicopters, both important to Australia.Read moreRead less
Inverse and related problems in statistics. Modern statistical inverse problems arise in fields from astronomy and biology to engineering and finance. Sometimes the problems involve the analysis of small samples of very high dimensional data, and are central to information aquisition in areas such as genomics and signal analysis. All these topics are of significant national importance, and their solution will bring national and community benefits. In addition, the program to which the proposa ....Inverse and related problems in statistics. Modern statistical inverse problems arise in fields from astronomy and biology to engineering and finance. Sometimes the problems involve the analysis of small samples of very high dimensional data, and are central to information aquisition in areas such as genomics and signal analysis. All these topics are of significant national importance, and their solution will bring national and community benefits. In addition, the program to which the proposal will lead will be used extensively for research training. In Australia, where the demand for research-trained statisticians greatly exceeds supply, this contribution to the nation and the community will be particularly important. Read moreRead less

These concepts also promise to lead to patentable new tools for ultra high-resolution imaging and for manipulating materials. This project will enhance Australia's international links, build on a range of national research programs, and provide training of researchers in photonics, which will be of benefit to Australian industry and research.Read moreRead less
Driving in the Fog: Speed Illusions Caused by Variations of Object Contrast. Accurate judgement of the speed of 3D motion is essential to many real world tasks, from driving a vehicle to playing sports. Illusions of perceived speed can occur when the range of brightness levels (ie. the contrast) is reduced, such as in fog, when suffering from cataracts, or when using some sunglasses. This raises issues of safety for drivers (pilots/captains etc). It is expected that advances in the understanding ....Driving in the Fog: Speed Illusions Caused by Variations of Object Contrast.

Illusions of perceived speed can occur when the range of brightness levels (ie. the contrast) is reduced, such as in fog, when suffering from cataracts, or when using some sunglasses. This raises issues of safety for drivers (pilots/captains etc). It is expected that advances in the understanding of these effects will inform road safety policy and practice to benefit drivers and pedestrians and to guide the manufacturing of eyewear and display devices (eg. military heads-up-displays). It is also anticipated that this project will be able to answer the much-debated question 'What colour should cricket balls be?'

The Myths of 1940. This study will investigate Britain in 1940, but many issues faced by that country then - the relationship between the political, military and intelligence leadership, public opinion and its influence on policy, political leadership and its influence on public opinion, war planning and fighting - remain as relevant to Australia today as they were to Britain during the Second World War.

The role of the military in a democracy and the benefits of military experience to political leaders are issues still much discussed today.Read moreRead less
High-Bandwidth Control and Advanced Dynamic Modelling for Unmanned Helicopters. Advanced control theory will be applied to enable precise control of unmanned helicopters in the presence of disturbances. This is critical for: operating unmanned helicopters among the buildings of urban environments, reconnaissance, investigating dangerous areas, pursuit of targets, and many other desirable capabilities for law enforcement and military purposes.

Advanced control theory will be applied to enable precise control of unmanned helicopters in the presence of disturbances. This is critical for: operating unmanned helicopters among the buildings of urban environments, reconnaissance, investigating dangerous areas, pursuit of targets, and many other desirable capabilities for law enforcement and military purposes. The ability of a small RUAV to launch and recover to a moving vessel would significantly enhance operational possibilities for border protection tasks and the Australian Defence Force. The research has direct application to other mechanical systems such as underwater vehicles, mobile robots, and precision control of agricultural vehicles, overhead cranes, and mining equipment.Read moreRead less
Target Identification with Ultra-Wideband Polarimetric Radar. Radar reflecting objects resonate when electromagnetically and appropriately excited. These resonances can be extracted from the returned radar signal and used to identify the object. A simile is identifying a tuning fork from its sound rather than its image.
