Australian Research Council - Discovery - Projects

Positrons in biosystems

Indicative Funding: $185,090 over 2 years (administered by Australian National University)
Summary: This project aims to improve our understanding of the damage processes in Positron Emission Tomography (PET). PET is a widely used medical imaging technique, but there are gaps in our understanding of the underlying interactions, in particular in the case of the radiation damage induced during the process. By using new models incorporating accurate descriptions of interactions processes, verified by experimental measurement, this project will develop a new model of positron transport in PET. The project will allow validation of predictions from the model by undertaking experiments in liquid water.
Investigators: James Sullivan, Ron White, Michael Brunger, Daniel Cocks and Joshua Machacek in collaboration with Gustavo Garcia and Jimena Gorfinkiel (Australian National University, College of Science & Engineering, Flinders University, Spanish National Research Council and The Open University (UK))

CRC for Developing Northern Australia Scheme - Projects

Applying new technologies to enhance biosecurity and cattle quality

Indicative Funding: $1,084,500 over 3 years (administered by Branir Pty Ltd & Trustee for Booloomani Unit Trust)
Summary: The vast natural environment of Northern Australia feeds the cattle industry; however, biosecurity threats have negatively impacted this. Conventional management of such threats such as weeds are not suited to such broad, harsh landscapes. The project will use an Internet of Things network with low-cost environmental sensors, drone mapping and big data analytics to develop and test data-driven, strategic pest management programs - ultimately improving both cattle industry and natural assets.

Australian Research Council - Discovery - Projects

Electron scattering and transport for plasma-liquid interactions

Indicative Funding: $595,120 over 3 years
Summary: The project addresses the emerging technologies associated with the interaction of plasmas with liquids and biological matter, including plasma medicine. The project expects to generate new knowledge on the role of electron-induced processes through the development of complete and accurate sets of microscopic cross- sections for electrons with biomolecules within tissue. This microscopic data will inform new microscopic models for non equilibrium electron transport in liquids and biological matter, and its coupling to plasmas. The expected outcomes of this project include progress towards the optimization of safety/efficacy of future generation plasma medicine devices through detailed understanding of plasma-biological tissue interactions.
Investigators: Ron White and Michael Brunger in collaboration with Zoran Petrovic and Jaime de Urquijo (College of Science & Engineering, Flinders University, Univerzitet u Beogradu and Universidad Nacional Autonoma de Mexico)

Department of Agriculture and Water Resources - National Landcare Programme

Applying new image recognition techniques for automatic detection and spraying of Harrisia cactus

Indicative Funding: $50,000
Summary: harrisia cactus is a significant rangeland weed in Queensland and bnorthern NSW. It competes against native species, inhibits stock accdess and endangers wildlife. JCU have developed image recognition software to identify Harrisia cactus in pasture; which has been deployed on a prototype robotic platform for selective spot spraying. This proect will see the development of a new spraying unit incorporating JCU's developed technology with a vehicle provided by Warrakirri Cropping. The unit will then be used to treat 500 ha of infested pasture at Warrakirri's "Willaroo" property. Its performance will be compared to traditional methods and showcased to local landholders.
Investigators: Mostafa Rahimi Azghadi, Brendan Calvert, Ron White and James Whinney in collaboration with Bill Manning, Matt West and Alex Olsen (College of Science & Engineering, North West Local Land Services, Warrakirri Cropping and Autoweed Pty Ltd)

Department of Agriculture and Water Resources - Control Tools and Technologies for Established Pest Animals and Weeds Programme

Improving the accuracy of weed killing robots with new image processing algorithms and near infra-red spectroscopy techniques

Indicative Funding: $271,772 over 3 years
Summary: Automated weed species recognition remains a major obstacle to the development and industry acceptance of robotic weed control technology. Particular problems occur in rangeland applications, including high light variability and weed-camera distance variability, which cause camera dynamic range problems, image blurring, and occlusion by other plants. This project aims to develop robust image recognition systems combined with Near Infra-Red spectroscopic methods for these complex rangeland environments with special emphasis on the broad-acre grazing pastures in North Queensland. The developed imaging systems will be suitable for all weed killing applications with particular emphasis given to foliar spot-spraying and Herbicide Ballistic Technologies.
