Wireless sensor and communication networks with fixed and mobile nodes are rapidly becoming essential technologies for hostile environmental monitoring, battlefield surveillance and precision agriculture. However, due to the complexities associated with interconnected design issues involving sensors, autonomous vehicles and communication protocols, even very simple networks have proven to be difficult to design. This project proposes to intelligently employ higher capabilities of mobile nodes and develop methods for rapid deployment, maintenance and routing that are aware of location, energy, and security. The outcomes of this project will form the basis for design of intelligent wireless networks for defence and civilian applications.Read moreRead less

Development of an active noise control system for sleeper seats on large commercial aircraft. Possible avenues will be investigated to actively reduce aircraft cabin noise experienced by passengers in sleeper seats, using localised active noise control (ANC). Previous work has focused on headsets and upright seat headrests which represent a different problem to the partially enclosed sleeper seats considered here. Efficiency and robustness problems that affect existing ANC systems will be addres ....Development of an active noise control system for sleeper seats on large commercial aircraft. Possible avenues will be investigated to actively reduce aircraft cabin noise experienced by passengers in sleeper seats, using localised active noise control (ANC). Previous work has focused on headsets and upright seat headrests which represent a different problem to the partially enclosed sleeper seats considered here. Efficiency and robustness problems that affect existing ANC systems will be addressed. A prototype system will be produced for a business class sleeper seat in a wide body aircraft. A second outcome is the establishment of a robust integrated system design procedure that can be used to quickly develop ANC systems for future designs.Read moreRead less
Scheduling and quality of service in Long Term Evolution telecommunications. There is an explosion of mobile telecommunications with over 50 billion connections expected by 2020. The next generation of mobile broadband will be based on a new technology known as Long Term Evolution (LTE) and, in this context, the goal of this project is to improve the efficiency of these systems by developing new techniques for scheduling.
Protecting Critical Transport Infrastructure using Hybrid Approaches for Interference and Spoofer Detection and Localisation. Modern infrastructure increasingly relies on the positioning and timing capabilities provided by the Global Navigation Satellite Systems (GNSS). GNSS signals, however, are vulnerable to interference and spoofing attacks. This vulnerability is aggravated as satellite navigation becomes more central to the operation of airports, ports, railways, and communications systems. ....Protecting Critical Transport Infrastructure using Hybrid Approaches for Interference and Spoofer Detection and Localisation. Modern infrastructure increasingly relies on the positioning and timing capabilities provided by the Global Navigation Satellite Systems (GNSS). GNSS signals, however, are vulnerable to interference and spoofing attacks. This vulnerability is aggravated as satellite navigation becomes more central to the operation of airports, ports, railways, and communications systems. Building on from earlier work by University of New South Wales, University of Adelaide and GPSat Systems, this project aims to create a system for locating interference and spoofers to GNSS of any power in real time, providing layered monitoring and reactive mitigation solutions against interference and spoofing attacks.Read moreRead less
Listen and see: Remote sensing and imaging of insect pests. Australia is the third largest market for termite control, after the USA and Japan. It has been estimated by CSIRO that about one in three Australian houses will be attacked by termites at some stage. Currently, an Australian designed, patented and manufactured product is the only reliable termite detector. This research, developing a novel sensor array and imaging technology, will further consolidate Australia's world leading position ....Listen and see: Remote sensing and imaging of insect pests. Australia is the third largest market for termite control, after the USA and Japan. It has been estimated by CSIRO that about one in three Australian houses will be attacked by termites at some stage. Currently, an Australian designed, patented and manufactured product is the only reliable termite detector. This research, developing a novel sensor array and imaging technology, will further consolidate Australia's world leading position in termite detection technology, revolutionise how termite behavioural research will be conducted and significantly increase the world-wide capability in termite control and hence reduce the costs of termite damage. It will deliver significant economic and environmental benefits to Australia.Read moreRead less
Non-invasive measurement of intracranial pressure by means of transcranial doppler blood flow and central aortic pressure. The investigation will produce a device that will aid doctors measuring brain pressure without drilling holes through the skull. The device will use the technology of an Australian company that has the only patented system to deduce the pressure in the brain by measuring pressure close to the heart and the brain and by recording the pressure pulse wave at the wrist. The comm ....Non-invasive measurement of intracranial pressure by means of transcranial doppler blood flow and central aortic pressure.

The device will use the technology of an Australian company that has the only patented system to deduce the pressure in the brain by measuring pressure close to the heart and the brain and by recording the pressure pulse wave at the wrist. The community benefit will be in terms of the safety and ease with which changes in pressure in the brain can be detected. It will also advance the world renowned Australian technology in a new area of application.Read moreRead less

This project aims to improve voice communication in immersive video conference technology for distance-based learning, using classrooms of students. research new theoretical approaches and develop new technology to transform the voice communication experience for co-located immersive video conferencing participants. When participants are co-located, two major audio issues—significant acoustic echo and instability—can arise; these are barriers to the wider adoption of this mode of education delivery. The expected outcome is an immersive video conferencing application deployed by the partner organisation. A key benefit will be a significantly enhanced product that provides a commercial advantage as well as a solution to remote learning for Australian students and educators.Read moreRead less
Automatic speech-based assessment of mental state via mobile device. This project aims to create the first mobile, device-based automatic assessment of mental state from acoustic speech. Focusing on novel approaches for eliciting speech, for regression-based scoring of mental state and for longitudinal modelling of speech, the project takes speech processing out of the laboratory and into realistic environments.

This project aims to create the first mobile, device-based automatic assessment of mental state from acoustic speech. Focusing on novel approaches for eliciting speech, for regression-based scoring of mental state and for longitudinal modelling of speech, the project takes speech processing out of the laboratory and into realistic environments. The project is significant because elicitation approach and longitudinal modelling have been acknowledged by the research community as challenges that are valuable to investigate, and because conventional regression methods are sub-optimal on ordinal mental state scales. This is significant commercially because mobile devices allow individually tailored, frequent and low-cost mental state assessment. Expected outcomes will include commercial-ready technology, trialled on Australians, accessible to everyone with a mobile device and concentration of Australian research and development capability in a rapidly growing application area.Read moreRead less
