Semantic change detection through large-scale learning. This project aims to develop technologies which understand the content of images before higher-level analysis is performed. This approach is intended to allow more accurate and reliable decisions to be made using automated image analysis than has previously been possible. The project will particularly investigate the detection of change in the contents of an image.
From data to action: a new process for developing injury countermeasures. This project aims to understand how reporting systems can improve workplace safety. Workplace injury affects over 600 000 Australian workers per year at a cost of approximately $60 billion. Although the introduction of incident reporting systems has enabled organisations to better understand the causes of injuries, how to translate this knowledge into effective countermeasures remains ambiguous. Moreover, it is not clear w ....From data to action: a new process for developing injury countermeasures. This project aims to understand how reporting systems can improve workplace safety. Workplace injury affects over 600 000 Australian workers per year at a cost of approximately $60 billion. Although the introduction of incident reporting systems has enabled organisations to better understand the causes of injuries, how to translate this knowledge into effective countermeasures remains ambiguous. Moreover, it is not clear whether adopting incident reporting systems actually leads to a safety benefit. This research intends to tackle these critical knowledge gaps by developing, implementing, and testing a process for translating incident reporting system outputs into appropriate and effective injury countermeasures, and then evaluating the safety effects of adopting the new incident reporting and learning cycle.Read moreRead less
Impact of recycled and low quality process water on sustainable mineral processing practices. Water is in short supply and needs to be considered as a 'key reagent'. The quality of this reagent can vary widely. For a sustainable mineral processing practice, the use of recycled or low quality/saline process water will be essential for a plant to operate in the future. The major benefit is recognition that significant recycle of process water for flotation is achievable if simple water quality con ....Impact of recycled and low quality process water on sustainable mineral processing practices. Water is in short supply and needs to be considered as a 'key reagent'. The quality of this reagent can vary widely. For a sustainable mineral processing practice, the use of recycled or low quality/saline process water will be essential for a plant to operate in the future. The major benefit is recognition that significant recycle of process water for flotation is achievable if simple water quality control and management practices are implemented. In addition, a better understanding and control of water quality in recycled/saline process water may lead to improved flotation stability and performance, and reduced reagent consumption.Read moreRead less

The multibillion-dollar wine industry forms a significant part of the Australian economy especially in regional areas. The application of high power ultrasound (HPU) to the cleaning and disinfection of wine barrels as well as for the enhancement of wine through improved fermentation and extraction of flavours and colours from grapes will have significant benefits to this industry. It is essential that Australia also capitalise on the benefits that this technology can provide in improved processing and products, lower costs, reduction in environmental pollution, water re-use and replacement of "dirty" energy. In this way the impact on this industry will help cement Australia's position in the world wine market long into the future.Read moreRead less

This project aims to equip the Australian public health and security sector with a tool to accurately measure tobacco consumption in the general population. Specific human biomarkers in urine will be identified using non-target approaches and their pharmacokinetics quantified. The new data will address critical gaps in our knowledge on the population-level excretion of biomarkers for the consumption of tobacco and alternative nicotine products. The outcomes of this project will provide reliable, cost-effective estimates of tobacco consumption for use with wastewater-based epidemiology assessments. This will enable changes in tobacco use to be accurately evaluated for the first time and improve the efficacy of tobacco control measures.Read moreRead less
Reducing the deleterious impacts of clay particle interactions with valuable minerals in copper and gold processing. This project seeks to understand the rheological behaviour of clay minerals and the effect of the viscosity caused by clay minerals on gas dispersion, the transport of network structures and the locking of the structures in the froth in mineral flotation. Novel methods will be developed to improve flotation separation by reducing the viscosity.

Engineering the sulphidising reactions for flotation of low quality ores. This project aims to engineer sulphidisation reactions to enhance the flotation of low quality ores for the minerals industry. Sulphidisation uses flotation to enrich base metal and precious minerals from low quality ores containing oxides and oxidised sulphides before expensive leaching or smelting. However, the current sulphidisation method is neither efficient nor widely used. This project will tailor sulphidisation reactions to generate desirable surface products that are not sensitive to flotation conditions. The intended outcome of this project is to provide a step change value in processing low quality resources while minimising the environmental effects of stockpiles.Read moreRead less
Regrinding chemistry and particle breakage mechanisms in increased surface hydrophobicity on fine and ultra-fine particles in mineral flotation. This project will study the effect of regrinding chemistry and particle breakage mechanisms on the redistribution of flotation collectors and the evolution of the metal oxidation species on mineral surfaces. New technologies will be developed to increase mineral surface hydrophobicity and therefore increase fine and ultra-fine particle flotation.
