Towards a high density silicon phase change memory device. This project builds upon our exciting recent findings that amorphous silicon can be transformed to a conducting crystalline phase following small-scale indentation. Furthermore the process is reversible as re-indentation can induce a transformation back to insulating amorphous silicon. This process appears to occur in extremely small (nanoscale) volumes of silicon. We plan to explore the viability of exploiting this behaviour to develo ....Towards a high density silicon phase change memory device. This project builds upon our exciting recent findings that amorphous silicon can be transformed to a conducting crystalline phase following small-scale indentation. Furthermore the process is reversible as re-indentation can induce a transformation back to insulating amorphous silicon. This process appears to occur in extremely small (nanoscale) volumes of silicon. We plan to explore the viability of exploiting this behaviour to develop an entirely new information storage system: a high-density silicon phase change memory. This project aims to study small-scale transformation behaviour in silicon and to design demonstrator memory devices based on both micro-electromechanical systems and solid state technologies.Read moreRead less

Onset Theory: Pushing the design envelope for textile composite structures. This study aims to exploit an innovative physics-based approach to predict the strength of textile composites. This is particularly important in areas such as aircraft design, where drastic weight savings are needed to allow designers to remain competitive in a low-carbon future. Improved theory and design tools will remove conservatism and account for a large part of these weight savings. The new approach is the first t ....Onset Theory: Pushing the design envelope for textile composite structures. This study aims to exploit an innovative physics-based approach to predict the strength of textile composites. This is particularly important in areas such as aircraft design, where drastic weight savings are needed to allow designers to remain competitive in a low-carbon future. Improved theory and design tools will remove conservatism and account for a large part of these weight savings. The new approach is the first to be consistent at all length scales — from atoms to aeroplanes — ensuring relevance for new and evolving composite material systems. A novel understanding of crack initiation in textile laminates is intended to reduce design and certification effort for new aircraft and help to design more efficient airframes at a lower cost.Read moreRead less
Integrating deep-earth and surface processes for frontier-basin exploration. It is well-known that mantle convection has a profound influence on basin evolution, and the next step will be to quantify this relationship and provide the science that will make these concepts applicable to exploration. To do this, we will develop a workflow to link plate-reconstruction software with the mantle convection modelling to link plate motions mantle convection and the history of sedimentation systematically ....Integrating deep-earth and surface processes for frontier-basin exploration. It is well-known that mantle convection has a profound influence on basin evolution, and the next step will be to quantify this relationship and provide the science that will make these concepts applicable to exploration. To do this, we will develop a workflow to link plate-reconstruction software with the mantle convection modelling to link plate motions mantle convection and the history of sedimentation systematically for the first time for frontier basin-scale applications. We will apply these emerging technologies to the evolution of basins in the Arctic borderlands frontier for resource exploration and on the Australian continent.Read moreRead less

Deterioration of structural integrity of ageing ships and marine platforms. This project will research the deterioration of structural integrity and remaining life of marine assets such as ships and offshore energy facilities, by integrating structural response analysis methods with aged-structure assessment techniques. Maritime assets exposed to ocean conditions suffer from time dependent phenomena, which reduce structural capability, affect safety and could have catastrophic environmental and economic consequences. Making assets available and affordably safe is a problem for operators. The key to prolonging asset life is in understanding the interrelationships over time between the asset’s structural condition and its use. Anticipated outcomes are superior safety, expected lifetime and economic benefits of maritime assets.Read moreRead less
From economic benefit to social cost: Antecedents of irresponsible gambling. The social impact of gambling is a challenge for policy-makers. Australia's gambling expenditure in 2001 contributed $4.4 billion in tax revenue. This economic benefit however, is offset by significant social costs ($1.8 to $5.6 billion). We will identify when and how distorted memory for previous gambling outcomes and gaming machine accessibility can cause irresponsible gambling. The results can be used to make informe ....From economic benefit to social cost: Antecedents of irresponsible gambling. The social impact of gambling is a challenge for policy-makers. Australia's gambling expenditure in 2001 contributed $4.4 billion in tax revenue. This economic benefit however, is offset by significant social costs ($1.8 to $5.6 billion). We will identify when and how distorted memory for previous gambling outcomes and gaming machine accessibility can cause irresponsible gambling. The results can be used to make informed assessments of the social impact of increasing the accessibility of gambling opportunities on local communities. The results can also be used to understand how gambling that contributes to the economy of a community becomes a social cost.Read moreRead less

Contemporary dance is one of the major vehicles through which Australian stories and cultural diversity are communicated. Little is known about the processes that underpin creation and performance of communicative dance works, and less still about processes and stylistic traditions unique to the Australian form. We will investigate cognitive and kinaesthetic processes involved in creating, refining, performing significant works. Combining experimental and practice-based research we examine psychological mechanisms engaged by elite choreographers, and experienced and emerging dancers, and analyse the unique Australian heritage and embodied knowledge evident in leading dancers and choreographers influenced by Gertrud Bodenwieser.Read moreRead less
