An analytical, phenomenological version of the successful "edge-to edge" matching approach to the morphology and crystallography of diffusion-controlled phase transformations will be developed. This will be incorporated in a Windows based computer program that can predict the essential features of precipitation (orientation relationships, habit planes, morphology and interface structure), from readily available input data for the two phases involved. It will provide a fuller understanding of diffusion-controlled phase transformations and the computer simulation will assist in the development of improved precipitation hardening alloys. In addition, a database of crystallographic data for typical metallic materials will be established in the project.Read moreRead less

The engineering strand addresses issues about methodology, modelling toolkits, and management and control. Practical applications are advanced via collaborative projects that address key issues in biology, environment, and socio-economics.Read moreRead less
The improvement of climate change investigations by developing and applying innovative evolutionary subset time series modelling using semi-parametric sparse-patterned approaches. With an estimated US$6.98 trillion loss indicated in the Stern review, severe climate change will make world climate conditions harsher and more likely include large natural climate disasters. The health of the Australian economy is critically dependent on decisions of environmental managers. However, most problems of ....The improvement of climate change investigations by developing and applying innovative evolutionary subset time series modelling using semi-parametric sparse-patterned approaches. With an estimated US$6.98 trillion loss indicated in the Stern review, severe climate change will make world climate conditions harsher and more likely include large natural climate disasters. The health of the Australian economy is critically dependent on decisions of environmental managers. However, most problems of complexity arising in climate change involve issues on which we do not possess a deep understanding. This project draws upon a set of inter-disciplinary concepts and models centred in neural networks that enable us to advance our understanding of complexity, leading to superior quantitative tools and models to allow for improved environmental decision-making.

A multiscale-multifunctional approach to advanced diagnosis and operator performance in complex process systems. Major process system failures and subsequent poor diagnosis continues to produce significant company disruption, environmental damage, injury and possible loss of life. The benefits of this work will be reduced impacts and risks. This work will provide a new integrated approach with structured tools and diagnostic designs for process industries.

Major process system failures and subsequent poor diagnosis continues to produce significant company disruption, environmental damage, injury and possible loss of life. The benefits of this work will be reduced impacts and risks. This work will provide a new integrated approach with structured tools and diagnostic designs for process industries. It should have direct impacts on company performance through improved diagnosis, more timely response and hence reduced likelihood of major accidents. It will help to improve overall risk management practice in the process industries with less impact on people, property and environment, thus improving operational performance. Local communities will be direct beneficiaries of these reduced risks.Read moreRead less
A Formal Approach to Resource Allocation in Service Oriented Marketplaces. There was a strong opinion at the 2004 World Economic Forum that interorganisational computing was a major factor in productivity improvements underpinning continuing economic growth in the developed world, and will continue to be so for the foreseeable future. The results of the proposed research are directed to advanced systems of this type, and will add momentum to Australia's Information Technology research community. ....A Formal Approach to Resource Allocation in Service Oriented Marketplaces.

The results of the proposed research are directed to advanced systems of this type, and will add momentum to Australia's Information Technology research community. Increased international recognition will positively impact on future interactions with the service composition research groups in Europe and the USA.Read moreRead less
Coordination and communication in critical care: Assessing potential technology support. This project will examine temporal coordination demands of busy critical care environments, with the goal of developing better models and tools for evaluating the impact of information and communication technology (ICT) innovation.

This project will examine temporal coordination demands of busy critical care environments, with the goal of developing better models and tools for evaluating the impact of information and communication technology (ICT) innovation. Millions of dollars can be wasted on healthcare ICT updates when the nature of critical care work, the means of communication, and temporal coordination demands are not fully understood. The outcome of this project will be better conceptual and computational tools for assessing the impact of ICT innovation on safety-critical systems such as healthcare, so providing more cost-effective ICT solutions where there is rapidly-evolving ICT innovation.Read moreRead less

Guaranteeing information security is of critical national importance, especially in the current political climate. Devices intended to safeguard Australia's electronic communications must be proven secure using leading-edge techniques. Currently, evaluation of such devices relies on informal procedures and the experience of individuals. This project will introduce more rigour into security evaluations by adapting techniques from the fields of safety analysis and formal methods. In particular, mathematical concepts will be introduced using notations suitable for use by security personnel with no prior formal methods experience. The outcomes of this project will enable more efficient and effective information security evaluations.Read moreRead less

Urbanisation has many negative effects upon native wildlife and their habitats, but biodiversity-friendly urban design and construction practices may greatly reduce these impacts. This study will examine the effectiveness of such measures at sustaining wildlife at sites of urban development, and will therefore produce significant benefits for local residents and the broader Australian community. Healthy natural ecosystems in urban areas provide many services to the public, reduce the need for costly management, and improve the livelihood of residents living in greener environments. This study will enhance all these community benefits through a detailed examination of the effectiveness of biodiversity-friendly urban development measures.Read moreRead less
Tracing the origins of stress in the symbionts of reef-building corals. Symbiotic dinoflagellates of corals are critical to the world's major tropical reef ecosystems. Recent work in our laboratories and others has revealed that these algae are sensitive to a wide array of stresses (including climate change) and hence may be the ?Achilles Heel? of reef ecosystems. This project will identify the key genes and processes in these algae using expressed sequence tags and microarray technology.

Recent work in our laboratories and others has revealed that these algae are sensitive to a wide array of stresses (including climate change) and hence may be the ?Achilles Heel? of reef ecosystems. This project will identify the key genes and processes in these algae using expressed sequence tags and microarray technology. On this basis, the underlying molecular mechanisms of these stress responses and their genetic diversity will be studied in order to better understand the differential susceptibility of reef-building corals to bleaching.Read moreRead less
