This research will benefit Australian Society through a better understanding and prediction of the response of aquatic systems to major shifts in the environment. Eutrophication and toxic algal blooms represent serious threats to the security of water supplies in Australia and elsewhere. Through development of high resolution technology (SPS), this project will provide the necessary knowledge and data for producing management tools capable of detailed predictions of the behaviour of aquatic systems. Successful management of Australian waters relies heavily on a better understanding of the scale dependent processes which govern the response to external perturbations such as increased nutrient export and consequent eutrophication.Read moreRead less

Metabolomics is an important new field of science that is contributing to the understanding of life processes at the molecular level. But a widely acknowledged major limitation of current metabolomics technologies is the inability to accurately identify high numbers of detected metabolites in the biological extracts being studied. This project will develop cutting-edge separation science approaches to address this existing problem in metabolomics analysis. In doing so it will provide enormous benefit to Australian biotechnology and biomedical research and play a major role in transferring capabilities to laboratories and research institutes that are involved in research aimed at elucidating biological pathways and networks.Read moreRead less

Phonon based condensed matter imaging. This project will exploit observations of phonon-based chemical contrast in the SHeM to determine the physics that underpins the imaging mechanism and use them to probe vibrational processes in condensed matter imaging. Imaging is an essential tool for the discovery, application and fabrication of new materials, structures and devices. However, many delicate structures are irrevocably degraded and changed when imaged using conventional microscopy. This team ....Phonon based condensed matter imaging. This project will exploit observations of phonon-based chemical contrast in the SHeM to determine the physics that underpins the imaging mechanism and use them to probe vibrational processes in condensed matter imaging. Imaging is an essential tool for the discovery, application and fabrication of new materials, structures and devices. However, many delicate structures are irrevocably degraded and changed when imaged using conventional microscopy. This team recently invented the scanning helium atom microscope (SHeM), which can image surfaces non-destructively with nanoscale resolution. They will use the SHeM to determine the new fundamental physics that underpins the imaging mechanism. Outcomes include turning SHeM into a tool that materials and biological scientists can use in laboratories worldwide.Read moreRead less
Integrity prediction of ground precision surfaces. This project aims to establish a new approach to enable a reliable and accurate prediction of precision surface grinding. Precision grinding is often the final step in the manufacturing chains for a broad range of metal, ceramic, optical glass and semiconductor components, which must have ultra-high surface integrity and accurate dimensions. To date, the surface integrity of a ground component cannot be predicted due to the involvement of many r ....Integrity prediction of ground precision surfaces. This project aims to establish a new approach to enable a reliable and accurate prediction of precision surface grinding. Precision grinding is often the final step in the manufacturing chains for a broad range of metal, ceramic, optical glass and semiconductor components, which must have ultra-high surface integrity and accurate dimensions. To date, the surface integrity of a ground component cannot be predicted due to the involvement of many random factors and variables in a precision surface grinding process, resulting in high failure rates and processes requiring repeated surface measurements. The novel approach for surface integrity prediction developed by this project will make a vital step forward in advancing the discipline of precision surfacing, establish a new knowledge base and bring about significant technological impacts to the manufacturing industry.Read moreRead less
Robust Control and System Identification of Highly Resonant Systems. The modelling and control of complex and highly resonant systems is of increasing engineering importance due to their occurence in a wide variety of emerging areas in aerospace, acoustics, robotics and ``smart'' structures. At the same time, effective tools tailored towards identifying the necessary models, and synthesising the necessary controllers for these systems are in their infancy. This arises from special difficulties ....Robust Control and System Identification of Highly Resonant Systems. The modelling and control of complex and highly resonant systems is of increasing engineering importance due to their occurence in a wide variety of emerging areas in aerospace, acoustics, robotics and ``smart'' structures. At the same time, effective tools tailored towards identifying the necessary models, and synthesising the necessary controllers for these systems are in their infancy. This arises from special difficulties encountered via the high dimensionality of the structures involved. This research project will employ new methods from the fields of robust control and multivariable system identification theory to lead to new and high performance solutions in this area.Read moreRead less

The economic wealth of Australia is underpinned by its remarkable biological diversity. However, land and water degradation are eroding Australia's natural asset base damaging industries such as tourism, fisheries, and forestry. Given limited funds for biodiversity conservation, we need to minimise the misallocation of resources by making wise investments. This research will result in frameworks and tools to ensure that we maximise the protection of biological diversity and the delivery of ecosystem services (such as clean water) that are important for human well-being. We will share the results of our research with decision makers, scientists, and the general public.Read moreRead less
Institutional transitions to sustainable agriculture: An inter-disciplinary analysis of a novel common-property resource governance system. Efforts to overcome the severe degradation of land resources supporting agriculture and human communities continue to be constrained by institutions and social norms.

Efforts to overcome the severe degradation of land resources supporting agriculture and human communities continue to be constrained by institutions and social norms. The knowledge needed for a transition to sustainable agricultural landscapes through institutional change is inadequate. A collaboration between specialists in economics, politics, sociology, ecology and soil science at the University of New England and graziers in an upper Murray-Darling subcatchment will analyse the transition to a common-property institution on this subcatchment. It will make a distinctively Australian contribution to international efforts to understand such transitions, and serve as a model for progress towards sustainability elsewhere in Australia.

This project aims to develop new brain imaging technology that adapts to and corrects for the motion of a responsive, freely moving mouse. Current technology requires the subject to be unconscious, precluding the use of imaging to study signalling pathways activated by external stimuli during cognitive and behavioural tasks. By harnessing new radiation detector, motion tracking and computational technologies, the project expects to bridge this technology gap and provide significant technical and conceptual advances in the field. This will provide important benefits, such as equipping neuroscientists with new tools to answer fundamental questions about how the mammalian brain regulates behavioural adaptation to a changing environment.Read moreRead less
