ResMed is a world leader in the technology of developing products for treating obstructive sleep apnea (OSA). ResMed provided the first successful non-invasive treatment of OSA with their sleep apnea device. Noise reduction is an important issue in the development of this product, since these devices operate on a bedside table. This project will enable the acoustic performance of these small irregularly shaped mufflers to be reliably predicted and optimised. The successful outcomes will improve the quality of the well-being of the user. This research also has relevance to the design of mufflers for use in broader applications such as locomotives and ferries.Read moreRead less

Summary
High-speed, three-dimensional, x-ray fluoroscopy for accurate measurement of human joint motion. This proposal addresses one of the most difficult and long-standing problems in the field of biomechanics: How can human joint motion be measured accurately and non-invasively during common activities such as walking, stair ambulation and running? Low-dose, high-speed, three-dimensional, x-ray fluoroscopy provides an excellent solution to this problem and, in so doing, can play a pivotal role in heal ....High-speed, three-dimensional, x-ray fluoroscopy for accurate measurement of human joint motion. This proposal addresses one of the most difficult and long-standing problems in the field of biomechanics: How can human joint motion be measured accurately and non-invasively during common activities such as walking, stair ambulation and running? Low-dose, high-speed, three-dimensional, x-ray fluoroscopy provides an excellent solution to this problem and, in so doing, can play a pivotal role in healthcare, through clinical gait analysis and gait rehabilitation (diagnosis, prevention and treatment of movement disorders); in sports, through the development of personalized training programs for elite athletes; and in entertainment, through the creation of physics-based animations for the video/digital games industry.Read moreRead less
Computer simulation techniques to reduce the incidence of femoral fracture after hip replacement surgery. Australia's ageing population is driving an increase of 5% to 10% a year in the number of primary total hip replacements. We will move beyond conventional surgical techniques, to deliver the science for an accurate, reliable computer-based system that is significantly more accurate and reliable. Optimising implant selection criteria to better match patients' activity levels and bone physiolo ....Computer simulation techniques to reduce the incidence of femoral fracture after hip replacement surgery. Australia's ageing population is driving an increase of 5% to 10% a year in the number of primary total hip replacements. We will move beyond conventional surgical techniques, to deliver the science for an accurate, reliable computer-based system that is significantly more accurate and reliable. Optimising implant selection criteria to better match patients' activity levels and bone physiology and minimise revision rates; this has major implications for the national health budget and patients' quality of life. Our advances will allow the implementation of improved surgical techniques that minimise the risk of implant related bone failure.Read moreRead less
The development of particle-depleted regions in dense suspensions of neutrally buoyant particles. We aim to measure the spatial variation of fluid speed and particle speed, and of particle concentration, across and along a pipe into which has been introduced a mixture of said particles and fluid. This problem has significance in mechanical and chemical engineering wherever particle/fluid mixtures are flowing. The expected outcomes are recognition of a major contribution to world research, as w ....The development of particle-depleted regions in dense suspensions of neutrally buoyant particles. We aim to measure the spatial variation of fluid speed and particle speed, and of particle concentration, across and along a pipe into which has been introduced a mixture of said particles and fluid. This problem has significance in mechanical and chemical engineering wherever particle/fluid mixtures are flowing. The expected outcomes are recognition of a major contribution to world research, as well as technological applications; one that motivates us is the blood shear in the bearings of a revolutionary Australian blood pump for cardiac assist that avoids both pivots and magnetic suspension for the single moving part.Read moreRead less
An innovative manufacturing technology enabling new generations of hip joint prostheses. The success of the present project will revolutionise the way we produce hip joint prostheses, resolve the critical issues caused by the wear of the hip joint bearing surfaces, and dramatically improve patients' life quality. The project will open an entirely new application field for the Australian made materials which have a very limited market so far. With the innovative technology and the new generations ....An innovative manufacturing technology enabling new generations of hip joint prostheses. The success of the present project will revolutionise the way we produce hip joint prostheses, resolve the critical issues caused by the wear of the hip joint bearing surfaces, and dramatically improve patients' life quality. The project will open an entirely new application field for the Australian made materials which have a very limited market so far. With the innovative technology and the new generations of hip joint prostheses, the international competitive edge of the Australian industry will be markedly sharpened. Patients, and the Australian economy, are expected to benefit greatly from successful developments in this project.Read moreRead less
