Our project will build new atmospheric density correction models (ADCMs) for accurate prediction of debris object and satellite orbits. This research will have tremendous impacts on realizing unaided debris laser ranging. An order of magnitude accuracy improvement to the ADCMs will lead to a significant breakthrough in space object tracking. The benefits of this research are: it will put Australia in a leading position in the world on ADCM study; to maintain Australia's leading role in space surveillance and greatly enhanced operational capability & efficiency of Australian space tracking systems; and to contribute significantly to the space environment info management, e.g. accurate collision warning and space junk tracking.Read moreRead less
Increasing internet energy and cost efficiency by improving higher-layer protocols. Australians rely heavily on our telecommunications infrastructure due to our geographic dispersion. We are also very susceptible to climate change, given our reliance on agriculture. Information technology is consuming a rapidly increasing fraction of our power and our budget. This research will help to reverse both those trends, by finding novel and practical ways to use our infrastructure more efficiently, and ....Increasing internet energy and cost efficiency by improving higher-layer protocols. Australians rely heavily on our telecommunications infrastructure due to our geographic dispersion. We are also very susceptible to climate change, given our reliance on agriculture. Information technology is consuming a rapidly increasing fraction of our power and our budget. This research will help to reverse both those trends, by finding novel and practical ways to use our infrastructure more efficiently, and to minimise its energy use. This will enable the Australian telecommunications industry to provide better service (including to Australian industries and rural communities) at lower economic and environmental cost. This project will put Australia on the international stage as a leading contributor to energy-efficient internet technology.Read moreRead less
Fatigue Life Prediction of Nano-filler Modified Composites. The proposed project aims to study the behaviour and the failure mechanisms of polymer nanocomposites under cyclic loading. The outcomes of the project will make original contributions to our knowledge base on such materials. The mechanics modelling and statistical analysis of the prediction of fatigue life will provide a sound physical basis and a useful tool for any future improvement and optimisation of the composites to achieve bett ....Fatigue Life Prediction of Nano-filler Modified Composites.

The proposed research will benefit Australia by creating a knowledge base in an internationally important area of chemistry. This will be aided by the return to Australia of an international leader in the field. Through an integrated and interdisciplinary approach, the exploitation of technologies arising from the research program will be explored. In addition to the academic community, these technologies will benefit hi-tech industries including pharmaceutical and fine chemicals concerns which will gain from the use of the proposed group 13 heterocycles in organic synthesis. Moreover, industries reliant on polymer supports in catalytic process or opto-electronic polymers will profit from the various polymers derived from phosphaalkynes.Read moreRead less
Why is the photosynthetic CO2-fixing enzyme, Rubisco, so inefficient? Dissection of the catalytic chemistry by computational simulation and experimental testing. Fixation of CO2 by the enzyme Rubisco during photosynthesis produces organic compounds which feed all life. Despite this critical role, Rubisco catalyses its reaction sluggishly and, worse, discriminates poorly between CO2 and O2, leading to useless products. Our combined expertise equips us to analyse Rubisco's mechanism using quantum- ....Why is the photosynthetic CO2-fixing enzyme, Rubisco, so inefficient? Dissection of the catalytic chemistry by computational simulation and experimental testing. Fixation of CO2 by the enzyme Rubisco during photosynthesis produces organic compounds which feed all life. Despite this critical role, Rubisco catalyses its reaction sluggishly and, worse, discriminates poorly between CO2 and O2, leading to useless products. Our combined expertise equips us to analyse Rubisco's mechanism using quantum-chemical methods and then test predictions experimentally. We will capitalise on our previous successful studies of Rubisco by addressing emergent issues which are the keys to understanding catalytic efficiency and CO2/O2 selectivity: the roles of a carbamylated lysine; the way CO2 addition is rendered irreversible; and the spin inversion inherent in O2 addition.Read moreRead less
