Plate Wave Tomography for Reconstruction of Laminar Defects. The proposed project promotes a conceptual advance in the application of plate waves for the quantitative reconstruction of laminar defects by investigating fundamental experimental and analytical aspects of a novel approach in plate wave ultrasonic tomography. A successful development will have a comparable significance in the area of health monitoring of thin structures as computer tomography had in medical imaging. Previous attempts ....Plate Wave Tomography for Reconstruction of Laminar Defects. The proposed project promotes a conceptual advance in the application of plate waves for the quantitative reconstruction of laminar defects by investigating fundamental experimental and analytical aspects of a novel approach in plate wave ultrasonic tomography. A successful development will have a comparable significance in the area of health monitoring of thin structures as computer tomography had in medical imaging. Previous attempts have ignored wave scattering effects, and therefore do not describe the correct physics of the problem. With its combined experimental-numerical approach, the proposed fundamental studies will help to identify the potential of plate wave ultrasonic tomography for in-situ health monitoring of realistic structures and smart materials design.Read moreRead less

The Role of Naturalism in Ontology and Scientific Methodology. Naturalism is the philosophical doctrine perhaps best described as a respect for the methods of the natural sciences. Although most contemporary philosophers would describe themselves as naturalists, exactly how this important doctrine is spelled out is a matter of much controversy. What is more, many substantial issues in both philosophy of science and in metaphysics depend crucially on how we understand naturalism. This project ....The Role of Naturalism in Ontology and Scientific Methodology. Naturalism is the philosophical doctrine perhaps best described as a respect for the methods of the natural sciences. Although most contemporary philosophers would describe themselves as naturalists, exactly how this important doctrine is spelled out is a matter of much controversy. What is more, many substantial issues in both philosophy of science and in metaphysics depend crucially on how we understand naturalism. This project will investigate the various conceptions of naturalism, looking at both their motivations and their implications for philosophy and scientific and mathematical methodology.Read moreRead less
From tourist siren to technological beacon: analysing the industrial function of the Sydney Opera House thirty years after its completion. The research will show that public buildings provide fertile ground to plant industrial seeds; but to have an impact on the local economy, they must respond to specific structural conditions or be supported by political will. These findings will improve Australia's institutional understanding of the relationship between cost and investment in construction, an ....From tourist siren to technological beacon: analysing the industrial function of the Sydney Opera House thirty years after its completion. The research will show that public buildings provide fertile ground to plant industrial seeds; but to have an impact on the local economy, they must respond to specific structural conditions or be supported by political will. These findings will improve Australia's institutional understanding of the relationship between cost and investment in construction, and clarify that the evaluation of building productivity requires a long-term perspective. Government agencies should use institutional projects to define their public face but also to plan and implement industrial strategies. The research will help Australia maximise its creative and technological capability by understanding the factors conducive to innovation and its acceptance.Read moreRead less
Mathematics, the science of real structure: an Australian realist philosophy of mathematics. The project will strengthen the already strong Australian philosophical tradition of realism, extending it into philosophy of mathematics. It will develop a robust alternative to the nominalism, Platonism and idealism that dominate northern-hemisphere philosophizing about mathematics, an alternative that is in tune with how mathematicians really apply mathematics. Australian philosophy will thus be stren ....Mathematics, the science of real structure: an Australian realist philosophy of mathematics. The project will strengthen the already strong Australian philosophical tradition of realism, extending it into philosophy of mathematics. It will develop a robust alternative to the nominalism, Platonism and idealism that dominate northern-hemisphere philosophizing about mathematics, an alternative that is in tune with how mathematicians really apply mathematics. Australian philosophy will thus be strengthened in general, giving it a greater attractiveness to the many overseas visitors and students who already appreciate its unique strengths. The nature of the project will also lead to closer ties and interdisciplinary work between philosophers and mathematicians.

Causes that make a difference: A philosophical theory of token-causation. Discussions of causation in philosophy and other disciplines raise matters of practical concern: for example, about how to improve causal explanations in economics, how to devise better ways of testing causal hypotheses in medicine, and how to automate procedures for discovering causal relations in agriculture. By clarifying the structure of causal concepts, the project will help in the efforts to address these problems, a ....Causes that make a difference: A philosophical theory of token-causation. Discussions of causation in philosophy and other disciplines raise matters of practical concern: for example, about how to improve causal explanations in economics, how to devise better ways of testing causal hypotheses in medicine, and how to automate procedures for discovering causal relations in agriculture. By clarifying the structure of causal concepts, the project will help in the efforts to address these problems, and so contribute indirectly to the national benefits that will accrue from solving them. A central aim of the project is to train several PhD students, the next generation of researchers, in this important field of enquiry.Read moreRead less
Contemporary scientific explanations of religion: A methodological and philosophical analysis. The idea that religion is an evolved feature of human nature plays a key role in the ongoing culture war between those critical of some aspects of the scientific worldview, especially the theory of evolution, and those who take it upon themselves to defend science against the perceived threat of religion, notably the so-called 'new atheist' media stars. Analysing the philosophical and methodological is ....Contemporary scientific explanations of religion: A methodological and philosophical analysis. The idea that religion is an evolved feature of human nature plays a key role in the ongoing culture war between those critical of some aspects of the scientific worldview, especially the theory of evolution, and those who take it upon themselves to defend science against the perceived threat of religion, notably the so-called 'new atheist' media stars. Analysing the philosophical and methodological issues raised by naturalistic explanations of religion will clarify the potential relationships between science and religion in a pluralist and predominantly secularist society like Australia in which the claims of science are accorded a special authority.Read moreRead less

Global Positioning System (GPS) technology can be used for precise deflection measurement of manmade structures such as buildings, bridges, etc. When integrated with additional signals from pseudolites (PL) that transmit GPS-like signals, changes in the height(s) of the monitored point(s) can be measured to millimetre accuracy. In collaboration with University of Nottingham researchers, a bridge structure in the U.K. will be used as a testbed, and will be the first time that PLs have been used for such an application. The expected outcomes include a suite of deformation monitoring algorithms capable of online analysis of the combined GPS-PL outputs.Read moreRead less
