Extraction of gold from thiosulfate leach liquors using selective magnetic ion exchange (MIEX) resins. Cyanide processes used for gold leaching can cause severe environmental problems. This proposal studies the use of thiosulfate as an alternative, concentrating on the design and synthesis of new functionalised magnetic ion-exchange resins, which will act as selective adsorbents for the gold thiosulfate complex and thereby facilitate the implementation of this efficient, low environmental impact ....Extraction of gold from thiosulfate leach liquors using selective magnetic ion exchange (MIEX) resins. Cyanide processes used for gold leaching can cause severe environmental problems. This proposal studies the use of thiosulfate as an alternative, concentrating on the design and synthesis of new functionalised magnetic ion-exchange resins, which will act as selective adsorbents for the gold thiosulfate complex and thereby facilitate the implementation of this efficient, low environmental impact process. Since the leaching is typically applied to ores rich in copper, resins for the recovery of copper will also be designed. Laboratory proving trials will be conducted and successful candidates will be considered for future commercialisation of a Resin-in-Pulp leaching and recovery process.Read moreRead less
Advanced matrix-analytic methods with applications. Over the last twenty-five years, matrix-analytic methods have proved to be very successful in formulating and analysing certain classes of stochastic models. Motivated by applications, this project will investigate more advanced matrix-analytic methods than have hitherto been studied.
Managing Fresh-Water Resources in Saline Environments. Australian industry and urban developments often rely on a secure supply of fresh water. In many situations, the fresh water occurs adjacent to large expanses of saline water. This poses special constraints on how the fresh water can be recovered. This project undertakes careful mathematical modelling of fresh water recovery from reservoirs and from within islands (where it may be the only practical source of drinking water). The injecti ....Managing Fresh-Water Resources in Saline Environments. Australian industry and urban developments often rely on a secure supply of fresh water. In many situations, the fresh water occurs adjacent to large expanses of saline water. This poses special constraints on how the fresh water can be recovered. This project undertakes careful mathematical modelling of fresh water recovery from reservoirs and from within islands (where it may be the only practical source of drinking water). The injection and extraction of ground water in novel "mineral leaching" mining technology will also be investigated.Read moreRead less

EON-ITNET will form an alliance with the Caltech-based GeoFramework, which is advancing a novel object-oriented data analysis environment, binding community software for Earth visualisation and simulation to 4D data bases.Read moreRead less
Tailoring composite propellers for reduced sound radiation. This project aims to explore the generation of noise by composite propellers and to use this understanding to tailor the composite properties to reduce underwater noise. Propellers are a harmful source of noise in the marine environment, disturbing animal behaviour, revealing the location of naval vessels and interfering with sonar operation. Adaptive composite propellers are potentially quieter than metal propellers, as well as offerin ....Tailoring composite propellers for reduced sound radiation. This project aims to explore the generation of noise by composite propellers and to use this understanding to tailor the composite properties to reduce underwater noise. Propellers are a harmful source of noise in the marine environment, disturbing animal behaviour, revealing the location of naval vessels and interfering with sonar operation. Adaptive composite propellers are potentially quieter than metal propellers, as well as offering improvements in efficiency and fuel consumption. The aims of this project are to understand the physical mechanisms associated with composite propeller noise generation. The outcomes are intended to provide advanced numerical capabilities that will support the development of quieter marine propeller designs to improve defence capability and the acoustic environment for marine mammals.Read moreRead less

The project will minimise the impact of the Greenhouse Pollution Reduction Scheme and anticipated rises in water costs on the householders. It will assist the consumers and the building industry in evaluating the environmental and economic costs and benefits of specific retrofitting actions for building envelope and major fixed appliances (thermal insulation, glazing, air infiltration, hot water, heating/cooling, lighting, low water flow and water reuse appliances, and solar photovoltaic systems). In addition to assisting a burgeoning renovation industry, the project will enable accurate assessment of the impacts of the Green Loans Program and guide future national and local energy and water reduction policies.

Fluorinated surfactants and hydrocarbons at coastal airports. Fluorinated surfactants and hydrocarbons at coastal airports. This project aims to develop a model and parameters that describe transport and co-transport of fluoro-surfactants and hydrocarbons, priority pollutants with a wide range of physico-chemical properties, at coastal airports.

Fluorinated surfactants and hydrocarbons at coastal airports. This project aims to develop a model and parameters that describe transport and co-transport of fluoro-surfactants and hydrocarbons, priority pollutants with a wide range of physico-chemical properties, at coastal airports. Sixty percent of Australian airports are in the coastal plain, and all are affected by contamination from internationally banned fluoro-surfactants and hydrocarbons. Their extensive past use at firefighting training grounds resulted in costly remediation worldwide. Understanding the fate of persistent fluoro-surfactants from point sources, and their role in transporting non-polar chemicals such as hydrocarbons, will improve risk-based decision making. This research is expected to form the basis for effective risk management and intervention strategies.Read moreRead less
An efficient approach to the computation of bacterial evolutionary distance. This project aims to apply advanced mathematical tools to improve our understanding of bacterial evolution. Bacteria account for as much total Earth biomass as all plant species put together, and have an unparalleled ability to evolve quickly and adapt to changing environments. Unfortunately, the existing mathematical models used to model bacterial evolution are generally computationally intractable. This project will r ....An efficient approach to the computation of bacterial evolutionary distance. This project aims to apply advanced mathematical tools to improve our understanding of bacterial evolution. Bacteria account for as much total Earth biomass as all plant species put together, and have an unparalleled ability to evolve quickly and adapt to changing environments. Unfortunately, the existing mathematical models used to model bacterial evolution are generally computationally intractable. This project will rectify this situation by using representation theory to transform combinatorial group theory into linear algebra, allowing for the application of advanced methods of numeric approximation. This will provide a better understanding of how bacteria evolve and improve our ability to manage their impact.Read moreRead less
Ecological-epidemiological models of feral swamp buffalo control in northern Australia. This research is locally, nationally and internationally significant because it 1) improves the capacity of the Northern Territory and its traditional aboriginal owners to manage together this prevalent species in an effort to minimise disturbance to native flora and fauna and to understand the long-term implications of continued proliferation, 2) provides a nationally relevant system to monitor and project t ....Ecological-epidemiological models of feral swamp buffalo control in northern Australia. This research is locally, nationally and internationally significant because it 1) improves the capacity of the Northern Territory and its traditional aboriginal owners to manage together this prevalent species in an effort to minimise disturbance to native flora and fauna and to understand the long-term implications of continued proliferation, 2) provides a nationally relevant system to monitor and project the spread of disease through feral animal populations in Australia, and 3) combines quantitative data and robust analytical tools that can be used as a template for solving many broad-scale feral animal problems around the world.Read moreRead less

An efficient healthcare system is essential for the well-being of any society. The aim of the project is to develop major advances in the mathematical modelling of healthcare systems, in order to improve efficiency, and ultimately, patient health. The first expected outcome is the development of mathematical models that constitute a high-level description of patient flow through hospitals and subacute care, so that demands for emergency and elective capacity are met given limited resources. The second is the development of a bed allocation algorithm that allocates patients to appropriate wards, so as to optimise the set of performance indicators of the system under appropriate constraints, given the current ward occupancy.Read moreRead less
