Gravity Current Driven Smoke Dispersion In a Stratified Ambient. Smoke from bushfires transported by gravity currents, and known to occur nationwide, caused the shutdown of businesses, education and events in Canberra in 2019. Recent scientific investigations have shown that the speed of propagation and concentration of smoke in these three-dimensional gravity currents have a long term ‘memory’ of their initial configuration. In this project, high-fidelity computational and experimental techniq ....Gravity Current Driven Smoke Dispersion In a Stratified Ambient. Smoke from bushfires transported by gravity currents, and known to occur nationwide, caused the shutdown of businesses, education and events in Canberra in 2019. Recent scientific investigations have shown that the speed of propagation and concentration of smoke in these three-dimensional gravity currents have a long term ‘memory’ of their initial configuration. In this project, high-fidelity computational and experimental techniques will be used to elucidate the fundamental mechanisms of gravity current entrainment and propagation. This knowledge will set a strong foundation to improve operational forecasts of smoke transport that will allow government agencies to better respond to the negative impact of these complicated flows.Read moreRead less
Understanding the Origin and Development of Extreme and Mega Bushfires. Extreme and megafires result in significant damage to property and infrastructure and are associated with large suppression costs. These events form when separate fires Merge. Their increase occurrence in recent seasons highlights the importance of developing tools and technologies that better predict extreme events to aid fire response and inform strategies for greater resilience.

Extreme and megafires result in significant damage to property and infrastructure and are associated with large suppression costs. These events form when separate fires Merge. Their increase occurrence in recent seasons highlights the importance of developing tools and technologies that better predict extreme events to aid fire response and inform strategies for greater resilience. This project combines fire field experiments with computer modelling to determine factors driving extreme fire development, and develop new knowledge and models. These enable better prediction of active fires, enhance the knowledge base of fire managers for critical decision making and to improve risk modelling and mitigation planning for fire-prone communities.Read moreRead less

At present there is a need for fast and detailed chemical analysis of complex samples, such as those important to biomedical diagnostics and forensic science. Innovative technology will be developed here in order to reduce analysis time whilst maintaining the integrity of the chemical information contained within the sample. This step change in separation science will directly aid biomedical diagnostics, forensic sample determination and industrial process monitoring through decreased analysis time with an increase in the chemical information gained. By performing chemical separations on a microfluidic scale a reduction in both the cost of analysis and impact of solvent waste on the environment will be achieved.Read moreRead less

Enterprise Resource Planning (ERP) implementation is one of the most pervasive sources of technological change in contemporary Australian enterprises. ERP systems are computer-based technologies that are designed to increase efficiency and achieve major cost savings across the entire organization. Their implementation has significant implications for the structure, nature and management of organizations. This project's innovative application of an organizational change model to eight detailed case studies across a range of organizational types will generate important new insights into the effects of ERP implementations at Australian organizations and help explain why some implementations are more successful than others.Read moreRead less
University learning in the digital age: Investigating how students learn online. Learning in higher education has become more complex since much of the founding research 40 years ago, with online technologies increasingly used to engage a diverse university student population in student-centred learning.

Learning in higher education has become more complex since much of the founding research 40 years ago, with online technologies increasingly used to engage a diverse university student population in student-centred learning. The proposed study aims to update our understanding of student learning to this contemporary university context. The project will focus specifically on how students interpret online tasks set by their teachers, how they complete those tasks by tracking their activities in real-time, and what outcomes they achieve. This study will advance fundamental understanding of these inter-related processes, and provide the stimulus to change thinking about educational design, teaching practices, and support for students.Read moreRead less
Complete blood fractionation using a low-cost microfluidic system. This project aims to understand particle focusing in inertial microfluidic systems to design efficient devices for cell sorting. The field of microfluidics could ultimately advance medical research but device design is primitive. Microfluidic particle separations are not thoroughly simulated before fabrication to predict performance. This project is expected to accelerate progress in design of efficient microfluidic devices.

New Pulsar Instrumentation for Gravitation Wave Detection and Understanding the Emission Mechanism. Millisecond pulsar timing currently provides the most sensitive method of detecting long-period gravitational waves which permeate the Universe. Parkes leads the world in the discovery and timing of millisecond pulsars. This has motivated the development of three new advanced instruments including a cyrogenic dual-band receiver, a very wide-band correlator and a baseband recorder with an in-built ....New Pulsar Instrumentation for Gravitation Wave Detection and Understanding the Emission Mechanism. Millisecond pulsar timing currently provides the most sensitive method of detecting long-period gravitational waves which permeate the Universe. Parkes leads the world in the discovery and timing of millisecond pulsars. This has motivated the development of three new advanced instruments including a cyrogenic dual-band receiver, a very wide-band correlator and a baseband recorder with an in-built supercomputer. We aim to exploit these new technologies to systematically study the pulsar population. We will establish a timing array which can detect gravitational waves, enable GLAST to identify over 100 gamma-ray pulsars and study the pulsar emission mechanism at sub-microsecond time resolution.

This project determines the fundamental science underpinning the operation of a novel hybrid chemical looping carbon reforming (CLCR) process for production of alternative transportation fuels with a reduced greenhouse gas emissions profile. Compare with conventional processes, the CLCR process features a 50 per cent reduction in the energy and carbon dioxide footprints and represents a large sink for carbon dioxide sequestration if deployed widely. To achieve the broad objectives of the project comprehensive experimental and modelling studies will be carried out at macro, micro and molecular levels. Expected outcomes include fundamental knowledge essential to the development and commercial-scale deployment of the CLCR process.Read moreRead less

This project aims to address the legal and policy dimensions of hepatitis C discrimination. Hepatitis C is a major public health challenge linked to profound discrimination, including in law and policy. Treatments introduced in 2016 improved cure rates; optimism about disease elimination is high, but questions remain about discrimination faced by those who are cured. This interdisciplinary project’s goal is to generate new knowledge about hepatitis C discrimination in a post-cure context, and identify opportunities for legal and policy reform. Expected outcomes of the project include better legal, social and policy outcomes for Australians cured of hepatitis C, significantly benefiting these individuals directly and society more broadly.Read moreRead less
