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

The aim of this project is to develop a sustainable process for producing biodegradable polyhydroxyalkanoate (PHAs)polymers from an innovative aerobic-anaerobic biological wastewater treatment process, ?treating? high strength food industry effluent. These biopolymers offer enormous potential for use as renewable and biodegradable thermoplastics.
It is proposed to investigate two process configurations, namely the sequencing batch reactor and a continuous two step anaerobic-aerobic reaction system. These will be studied at bench-scale. The outcomes include:
1. Determination of the optimum microbial conditions and key growth
parameters for the production of PHA.
2. Optimisation of the process configuration, operating strategies
and operating conditions to maximise the
production of PHA.
3. Assessment of the influence of the feed composition (e.g. VFA)
on the PHA composition (PHB/PHV).

Methane is a powerful greenhouse gas, and its release in deep oceans and permafrost regions due to decomposition of methane hydrate, an ice-like crystalline, could potentially pose devastating threat to mankind. On the other hand, methane hydrate represents a vast energy potential to Australia and the remainder of the world. Understanding the mechanism of gas hydrate formation and dissociation is of fundamental importance to methane extraction and capture. This project employs state-of-the-art surface analytical tools to explore the mechanism of gas hydrate formation. The outcomes will strengthen Australia's leading role in scientific and technological development in this field. 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

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.

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
Sequencing and assembling microbial community metagenomes in real-time. This project aims to assemble metagenomes directly from environmental samples using nanopore sequencing. Short-read approaches to metagenomics cannot assemble mixed genomes from an environmental sample, so focus on describing which species and genes are present. Long-read nanopore sequencing enables the assembly of full genomes of multiple species in a sample. Assembling complete genomes in important resources such as water ....Sequencing and assembling microbial community metagenomes in real-time. This project aims to assemble metagenomes directly from environmental samples using nanopore sequencing. Short-read approaches to metagenomics cannot assemble mixed genomes from an environmental sample, so focus on describing which species and genes are present. Long-read nanopore sequencing enables the assembly of full genomes of multiple species in a sample. Assembling complete genomes in important resources such as water and soil should lead to deeper understanding of the dynamics, variation and transfer of genetic material within these resources’ microbial communities, strategies to manage microbial diversity, and improved productivity and long-term sustainability for these resources.Read moreRead less

Disinfection of drinking water is a successful measure to reduce water-borne diseases and protect health. However, epidemiological evidence links bladder cancer to disinfection by-products formed during drinking water treatment. Despite decades of research the causative agents remain to be identified. To fill this knowledge gap, this project will quantify the fraction of toxicity that cannot be explained by known chemicals in water samples treated with different disinfectants using a combination of chemical analysis and in-vitro bioassays. Samples with high unexplained effects will then be fractionated to isolate toxicologically relevant disinfection by-products, which will ultimately be identified with non-target chemical analysis.Read moreRead less
