Discovering how termites use vibrations to thrive in a predators' world. Our recent research revealed termites use vibrations to avoid predators/competitors for survival. However, the enabling mechanisms of this amazing ability remain unknown. The project aims at unlocking the secrets of these mechanisms by relating the mechanical properties of termite, legs, antennae and sensing organs (measured with advanced micro measurement techniques) to vibration signatures of ants and termites (extracted ....Discovering how termites use vibrations to thrive in a predators' world. Our recent research revealed termites use vibrations to avoid predators/competitors for survival. However, the enabling mechanisms of this amazing ability remain unknown. The project aims at unlocking the secrets of these mechanisms by relating the mechanical properties of termite, legs, antennae and sensing organs (measured with advanced micro measurement techniques) to vibration signatures of ants and termites (extracted using innovative signal processing techniques and nonlinear dynamics). We will develop novel bio-dynamics models that incorporate machine learning. We will test the models’ ability to manipulate termites foraging behaviour, with the ultimate objective of developing chemical-free, vibration-based pest control devices. Read moreRead less
Cooperative control of networked systems with constraints. This project aims to address the challenge of networked systems in deploying teams of robotic agents. Control of the networked system is extremely difficult due to real world constraints imposed on each agent. This project will focus on motion constraints, equipment/capability constraints, and spatial constraints. In addition to theoretical advances, the wider scientific community will benefit directly, because the control algorithms dev ....Cooperative control of networked systems with constraints. This project aims to address the challenge of networked systems in deploying teams of robotic agents. Control of the networked system is extremely difficult due to real world constraints imposed on each agent. This project will focus on motion constraints, equipment/capability constraints, and spatial constraints. In addition to theoretical advances, the wider scientific community will benefit directly, because the control algorithms developed are expected to allow straightforward deployment of robotic teams. There are myriad applications for cooperative robotic agents, ranging from surveillance, to environmental monitoring using underwater and aerial drone formations – with an array of benefits and impacts including economic, commercial and societal. The results are intended to ensure and cement Australia’s front-line position in the current technological revolution known as “Industry 4.0”.Read moreRead less
Using genetic Allee effects to manage invasive populations. An invasion can be started with only a small number of individuals, and it is very difficult to reliably detect these individuals. This project aims to develop new genetic technology that can send small founder populations extinct without affecting large populations. This technology removes the problem of having to detect small populations; these small populations will go extinct on their own, without the need for management interventio ....Using genetic Allee effects to manage invasive populations. An invasion can be started with only a small number of individuals, and it is very difficult to reliably detect these individuals. This project aims to develop new genetic technology that can send small founder populations extinct without affecting large populations. This technology removes the problem of having to detect small populations; these small populations will go extinct on their own, without the need for management intervention. This technology could be used to prevent establishment and spread of invasive species and agricultural pests. Through a combination of experimentation and modelling, the project develops this technology and assesses its use in applied problems ranging across environment, agriculture, and health.Read moreRead less
Development of novel inerter-based damper for platform vibration control. This project aims to develop a novel inerter-based damper to mitigate the excessive vibrations of offshore floating platforms (OFP), which are widely used in the offshore industry for oil exploration. Harsh environmental loads such as wind and waves can induce excessive vibrations to OFPs and endanger their safety and stability. This project aims to develop a novel inerter-based damper that can produce a considerable appar ....Development of novel inerter-based damper for platform vibration control. This project aims to develop a novel inerter-based damper to mitigate the excessive vibrations of offshore floating platforms (OFP), which are widely used in the offshore industry for oil exploration. Harsh environmental loads such as wind and waves can induce excessive vibrations to OFPs and endanger their safety and stability. This project aims to develop a novel inerter-based damper that can produce a considerable apparent mass that is much larger than its physical mass through an amplifying mechanism by translating the linear motion into high-speed rotational motion, which can significantly reduce the mass and cost of the damper. Benefits of the project include more economical and safer OFP designs, which are expected to improve the competitiveness of Australian pillar oil and gas industries.Read moreRead less
How brain oscillations influence our behaviour. This project aims to reveal how sudden, intense stimuli impair or facilitate concurrent actions. Startling sounds can disrupt the execution of movements and distract attention from vital events in the environment, with potential disastrous consequences when handling complex equipment such as airplanes, cars and trucks, or surgical instruments. This project will combine classic experimental and novel neuro-modulatory techniques with the measurement ....How brain oscillations influence our behaviour. This project aims to reveal how sudden, intense stimuli impair or facilitate concurrent actions. Startling sounds can disrupt the execution of movements and distract attention from vital events in the environment, with potential disastrous consequences when handling complex equipment such as airplanes, cars and trucks, or surgical instruments. This project will combine classic experimental and novel neuro-modulatory techniques with the measurement of oscillatory brain activity. Expect outcomes will inform theories of cognitive function and the design of interventions to reduce the negative effects of sudden, distracting events.Read moreRead less
Unlocking the mechanisms of vibro-acoustic communication in termites . Our understanding of how termites use microvibrations to communicate is limited, as the generation, transmission and detection of these complex vibrations in substrates at the submillimetre scale are unknown. We aim to develop a fully validated vibro-acoustic termite communication model which will be used in Swårmalätørs to demonstrate their ability to synchronise and mimic collective behaviour. This will be achieved by combi ....Unlocking the mechanisms of vibro-acoustic communication in termites . Our understanding of how termites use microvibrations to communicate is limited, as the generation, transmission and detection of these complex vibrations in substrates at the submillimetre scale are unknown. We aim to develop a fully validated vibro-acoustic termite communication model which will be used in Swårmalätørs to demonstrate their ability to synchronise and mimic collective behaviour. This will be achieved by combining novel acoustic levitation, microsystem analyses and electrophysiology to determine physical properties of termite appendages, sensory and behavioural thresholds; and by considering wave transmission characteristics in wood, friction-adhesion at the termite feet, mandible cutting and soldier alarm drumming.Read moreRead less

The project aims to develop a conceptual framework and algorithms for handling multi-vehicle formation control. Formations of unmanned airborne vehicles are currently used by defence forces and swarms of micro-vehicles are beginning to find increasing use in defence and for civilian emergency response, largely for surveillance purposes. Vehicles must cooperate to achieve a global formation objective, while respecting constraints on sensors, energy, and general mechanical limitations. The project aims to resolve the challenges of deciding what a single vehicle should observe, what and to where it should communicate, and how it should move in relation to what it sees. The conceptual framework developed may also be relevant in guiding future defence acquisitions and civilian applications.Read moreRead less

This will allow increased reliability of comprehensive biomechanical models used to simulate realistic injury and surgery scenarios.
The problem is significant and urgent. Every year in Australia, there are over 22,000 cases of traumatic brain injury, some of which could be prevented by better passive and active countermeasures; and over 12,000 neurosurgical procedures that surgical simulation could make more accurate and therefore safer.Read moreRead less

This project seeks to deliver a definitive understanding of the behaviour of steady and pulsating fluid flow through compliant-walled channels and pipes. Novel theoretical stability-analyses and experimental investigations, complemented by targeted numerical simulations, will be developed and used to identify and categorise fluid- and wall-based wave-disturbances and their interactions. This can underpin the development of technologies that control these flows to advantage in both engineered fluid-flow and biologically occurring systems. Robust design guidelines will emerge to safeguard and enhance the use of compliant liners and flexible panels for drag and noise reductions, or to protect surfaces exposed to fluid flows.
