Quantifying the Accessibility of Urban Development Proposals: Moving Towards Sustainability in Urban Growth and Renewal. Improved accessibility, particularly by non-automobile transport modes, is an explicit goal in transport, environment, and land use policies. The hypothesis to be tested is that it is possible to develop a measure to assess the potential of any proposed urban development, whether it be new urban growth or an urban renewal/in-fill project, to achieve sought after changes in tra ....Quantifying the Accessibility of Urban Development Proposals: Moving Towards Sustainability in Urban Growth and Renewal. Improved accessibility, particularly by non-automobile transport modes, is an explicit goal in transport, environment, and land use policies. The hypothesis to be tested is that it is possible to develop a measure to assess the potential of any proposed urban development, whether it be new urban growth or an urban renewal/in-fill project, to achieve sought after changes in travel behaviour that will move urban development in sustainable directions. The proposal develops a GIS-based decision-support system that uses accessibility as an attribute of a land use development proposal rather than as an attribute of the transport system.Read moreRead less
Minimizing hypersonic skin-friction by boundary-layer combustion. The high drag associated with hypersonic flight has been a major obstacle to development of hypersonic aircraft. It is generally accepted that half the drag of hypersonic vehicles will be caused by air friction on the aircraft's skin, due mainly to the turbulent boundary layer which forms on the skin. However, a new method of reducing skin friction, by injecting and burning fuel in the boundary layer, has been discovered. This ....Minimizing hypersonic skin-friction by boundary-layer combustion. The high drag associated with hypersonic flight has been a major obstacle to development of hypersonic aircraft. It is generally accepted that half the drag of hypersonic vehicles will be caused by air friction on the aircraft's skin, due mainly to the turbulent boundary layer which forms on the skin. However, a new method of reducing skin friction, by injecting and burning fuel in the boundary layer, has been discovered. This project is aimed at investigating the range of conditions under which this method will be effective. By this boundary-layer "lubrication" much more efficient hypersonic flight will be possible.Read moreRead less
Enhancing scramjet performance by boundary layer combustion. Australia has developed a strong international reputation over the past 20 years for excellence in research into hypersonic flight technologies. This helps to reinforce the fact that this is a country in which advanced technologies can be conceived and developed. Australian companies and agencies are already collaborating with and are being supported by international organizations to develop further hypersonic flight technologies.

Australia has developed a strong international reputation over the past 20 years for excellence in research into hypersonic flight technologies. This helps to reinforce the fact that this is a country in which advanced technologies can be conceived and developed. Australian companies and agencies are already collaborating with and are being supported by international organizations to develop further hypersonic flight technologies. Achieving another significant advance in this area by demonstrating significant reductions in frictional drag on hypersonic vehicles will keep us at the forefront of this field and lead to continued international support and collaboration.Read moreRead less
Fluid-structural interactions in high-speed flows. This project aims to perform experiments to measure fluid-structure interaction in hypersonic flows. The work will improve the accuracy of simulation tools that are urgently required to aid industry in the design of more structurally efficient and robust high-speed vehicles. These tools will in turn be used to reveal the underlying physics of the fluid-structure interactions and establish the relative significance of the driving parameters. Accu ....Fluid-structural interactions in high-speed flows. This project aims to perform experiments to measure fluid-structure interaction in hypersonic flows. The work will improve the accuracy of simulation tools that are urgently required to aid industry in the design of more structurally efficient and robust high-speed vehicles. These tools will in turn be used to reveal the underlying physics of the fluid-structure interactions and establish the relative significance of the driving parameters. Accurate prediction of the behaviour and lifetime of structural components subject to these fluid-structural interactions, in which the deformation of the structure induced by the local flow field, can in turn influence this flow field. This coupling can result in damage or even catastrophic structural failure and thus robust design tools must be developed to avoid this.Read moreRead less
Proactive detection of motor vehicle crash black spots based on their underlying behavioural, engineering, and spatially related causes. Road traffic crashes are responsible for about 1400 fatalities and 32,500 injuries on Australian roadways each year. A significant research opportunity exists to fundamentally rethink how the profession quantitatively identifies black spots on the transport network. The first project aim is to develop, test, and validate an evidence based methodology to proacti ....Proactive detection of motor vehicle crash black spots based on their underlying behavioural, engineering, and spatially related causes. Road traffic crashes are responsible for about 1400 fatalities and 32,500 injuries on Australian roadways each year. A significant research opportunity exists to fundamentally rethink how the profession quantitatively identifies black spots on the transport network. The first project aim is to develop, test, and validate an evidence based methodology to proactively detect motor vehicle crash black spots. The second aim is decompose (statistically) observed crashes at a site into their engineering, behavioural, and unobserved spatial components. The new methods combined will lead to fundamentally novel insights and knowledge regarding transport network safety management, in turn leading to reductions in the Australian road toll.Read moreRead less

The project will provide benefits for society, both in terms of its contribution to scientific knowledge and understanding, and potential applications for end users. The question of how people prioritise tasks, set goals, and apply effort is of fundamental importance for understanding human behaviour. Society benefits from basic research into this question, because it allows us to understand the sources of (and limits to) human resilience. The results have wide application in military, industrial and commercial settings. Examples include the development of tools for training people more effectively, managing their workload, and improving their performance.Read moreRead less
