Modelling and Measurement of Flow-Structure Dynamics in the Human Upper Airway. Sleep disruption due to the common and disabling conditions of snoring and obstruction of the human upper airway can result in chronic fatigue, lost work and accidents caused by daytime drowsiness. To date the behaviour of the upper airway has not been adequately studied in terms able to reveal the mechanical causes of these conditions. This deficiency is addressed through the development and use of simulation tools ....Modelling and Measurement of Flow-Structure Dynamics in the Human Upper Airway. Sleep disruption due to the common and disabling conditions of snoring and obstruction of the human upper airway can result in chronic fatigue, lost work and accidents caused by daytime drowsiness. To date the behaviour of the upper airway has not been adequately studied in terms able to reveal the mechanical causes of these conditions. This deficiency is addressed through the development and use of simulation tools and measurement techniques that will elucidate the flow-structure dynamics leading to new diagnostic and improved treatment methods. Simulating the effect of treatment on any individual will permit it to be chosen to maximise its efficacy for a problem that costs the nation an estimated $2 Billion per year in lost productivity.Read moreRead less
Building a Smart Diagnostic System for Low Back Ailments. This research will develop an early back ailment diagnostic system that will reduce the recurrence of low back pain, and hence reduce the cost to the health system. This is significant to the community from prevention of pain, to the health care system that spends billions of dollars combating this modern day ailment and towards the industry where the low back pain is the single largest reason for sick leave in Australia.

This is significant to the community from prevention of pain, to the health care system that spends billions of dollars combating this modern day ailment and towards the industry where the low back pain is the single largest reason for sick leave in Australia. It will also give rise to employment of skilled technical people and an opportunity to increase high-value exports from Australia.Read moreRead less
Enhancing the independence of the severely disabled: Improving the detection rates of an EEG based brain computer interface (BCI). Severe disability costs the Australian economy and society billions of dollars each year and the population of severely disabled is steadily increasing. Also, disability results in impairments that can traumatically alter a person's life. The outcomes of this project will result in substantial national benefits by (i) optimising technology that will greatly improve t ....Enhancing the independence of the severely disabled: Improving the detection rates of an EEG based brain computer interface (BCI). Severe disability costs the Australian economy and society billions of dollars each year and the population of severely disabled is steadily increasing. Also, disability results in impairments that can traumatically alter a person's life. The outcomes of this project will result in substantial national benefits by (i) optimising technology that will greatly improve the life of the disabled by enhancing their ability to control their environment, (ii) situating Australia in the forefront of disability technology research and development, and (iii) enhancing the development of knowledge in research training students in the biomedical area.

Minimally invasive monitoring of sleep for disease management. Sleep, diet and exercise are the three pillars of wellbeing with poor sleep associated with medical issues such as obesity and congestive heart failure. This project will advance sleep analysis by researching new ways of monitoring that are highly accurate and convenient, enabling physicians to improve the monitoring of significant health issues.
Matched experimental observation and finite-element simulation of flow-induced oscillations in uniform and tapered-stiffness collapsible tubes. Flexible tubes that can be flattened are widespread in the body and can act to limit flow-rate. Limitation is usually associated with spontaneous oscillation (repetitive opening and closing). There are many candidate explanations, but none has been shown to correspond with a given experiment. Through computer models and matched experiments on this couple ....Matched experimental observation and finite-element simulation of flow-induced oscillations in uniform and tapered-stiffness collapsible tubes. Flexible tubes that can be flattened are widespread in the body and can act to limit flow-rate. Limitation is usually associated with spontaneous oscillation (repetitive opening and closing). There are many candidate explanations, but none has been shown to correspond with a given experiment. Through computer models and matched experiments on this coupled system (the fluid flow interacts with the tube shape), we seek to demonstrate for the first time that a given theory/computer model encompasses the physics controlling a given observed oscillation. The solution will find application in other flexible-structure design problems in engineering, and also potentially in medicine.Read moreRead less

Flow-induced oscillation in flexible tubes: experimental and numerical investigation of mechanism and onset. We seek to understand when instability arises in flow over very deformable structures. This will help us to design highly flexible structures specifically either to avoid the danger of flow-induced oscillations, which may be damaging (cardiac surgery, sails, parachutes), or in other circumstances to take advantage of them as an innovative way involving no sliding-parts mechanisms to crea ....Flow-induced oscillation in flexible tubes: experimental and numerical investigation of mechanism and onset. We seek to understand when instability arises in flow over very deformable structures. This will help us to design highly flexible structures specifically either to avoid the danger of flow-induced oscillations, which may be damaging (cardiac surgery, sails, parachutes), or in other circumstances to take advantage of them as an innovative way involving no sliding-parts mechanisms to create vibration, or flow pulsation, or sound, or motion (as in swimming-pool cleaners). Confidence in designing with highly flexible tubes will allow minimal resource consumption in manufacture of products to transport fluids, and will allow design use of the flow limitation property, whereby such a tube can control flow-rate.Read moreRead less
Towards early detection of upper airway obstruction in children: investigation of autonomic control. This project focuses on the investigation of new indicators for early detection of upper airway obstruction (UAO)-which is a common sleep disorder in children. Failure to treat UAO can result in serious adverse outcomes including failure to thrive, neurocognitive deficits, developmental delay, behavioural disorders and cardiovascular disease. Thus, early treatment of UAO will significantly improv ....Towards early detection of upper airway obstruction in children: investigation of autonomic control. This project focuses on the investigation of new indicators for early detection of upper airway obstruction (UAO)-which is a common sleep disorder in children. Failure to treat UAO can result in serious adverse outcomes including failure to thrive, neurocognitive deficits, developmental delay, behavioural disorders and cardiovascular disease. Thus, early treatment of UAO will significantly improve quality of life for the child. Direct benefits to community health via reduced costs for medical treatment will also be a key outcome. The establishment of new diagnostic indicators will form the basis of new tools for identifying child sleep disorders and contribute to advancing Australia's international leading position in health technology.

Braille is an important language used by the blind to read and write and Braillers are needed for everyday communication. This justifies the development of a light weight, transportable unit that is accessible at all times. This project proposes a relatively inexpensive, light weight, reliable and easily maintained Braille transcription system. The significant aspects of the proposed brailler include;
- An Electromagnetically compatable (EMC)12 Volt Power Supply allowing the common car battery as a backup power source.
- Use of modern plastics (PTFE) to reduce weight, maintenance and EMC standards.
- An embedded system for Forward and Back translation of literary Braille
- Protocol development and specification for USB keyboard and (standard) printer.Read moreRead less
