TRANSIENT VIBRATION IN PIPELINE SYSTEMS. Although the threat of transient vibration to the safety of pipeline systems has been widely recognised, neither the coupling characteristics in transient wave propagation are clearly understood, nor accurate tools are available for analysing them. The aims of this project are to develop effective analytical and experimental methods, to study the interactions between transient waves of different types at pipe joints and bends, and to experimentally charac ....TRANSIENT VIBRATION IN PIPELINE SYSTEMS. Although the threat of transient vibration to the safety of pipeline systems has been widely recognised, neither the coupling characteristics in transient wave propagation are clearly understood, nor accurate tools are available for analysing them. The aims of this project are to develop effective analytical and experimental methods, to study the interactions between transient waves of different types at pipe joints and bends, and to experimentally characterise the transient excitations. The understanding and techniques developed from this project hold promise in providing reliable tools for safe design of complex pipeline systems in petroleum, chemical and refinery industries.Read moreRead less
Putting an end to hospital-borne infection with micronebulisation of lung-safe disinfectants. Dangerous infections are unfortunately common in hospitals, established and retransmitted via surfaces and handheld items, representing a leading contributor to death worldwide, and potentially a far more serious problem to come as antimicrobial resistance worsens. The project aims to exploit a newly discovered and unique low power nebulisation technology to nebulise a strongly antiviral, antibacterial ....Putting an end to hospital-borne infection with micronebulisation of lung-safe disinfectants. Dangerous infections are unfortunately common in hospitals, established and retransmitted via surfaces and handheld items, representing a leading contributor to death worldwide, and potentially a far more serious problem to come as antimicrobial resistance worsens. The project aims to exploit a newly discovered and unique low power nebulisation technology to nebulise a strongly antiviral, antibacterial and antifungal agent, triethylene glycol that is too viscous to do so by any other known method. Through refinement and engineering of the technology via this project, handheld and room-based continuously operating nebulisers will produce continuous microdroplet mists of these pathogen-killing agents that deposit on surfaces throughout a hospital.Read moreRead less
Higher Order Effects in Miniaturized Piezoelectric Devices. The national benefits of this project are: (a) We will provide opportunities to two postdoctoral researchers to pursue cutting edge research on electromagnetic radiation/scattering and self-heating phenomena in microelectronic devices involving ultrathin lossy electrodes. (b) We will provide industry-oriented research on coating and shielding problems in microelectronic devices to two postgraduate students. (c) We will team up with worl ....Higher Order Effects in Miniaturized Piezoelectric Devices.

(b) We will provide industry-oriented research on coating and shielding problems in microelectronic devices to two postgraduate students. (c) We will team up with world leading industrial partners and transfer high-tech know-how to Australia. (d) The outcomes of our research will position Australia as the prime focal point for the design, modelling and simulation of microacoustic devices.Read moreRead less
Flute properties without players, and without flutes. This project will measure how the acoustic impedance spectra of some flutes depend upon the detailed shape of the bore and the size, shape and position of the holes. It will develop a model to predict, for the benefit of instrument makers, the effect of proposed changes in the geometry of the instrument on the pitches and ease of playing of notes played on the instrument. Importantly, it will allow museum curators to determine tunings and (un ....Flute properties without players, and without flutes. This project will measure how the acoustic impedance spectra of some flutes depend upon the detailed shape of the bore and the size, shape and position of the holes. It will develop a model to predict, for the benefit of instrument makers, the effect of proposed changes in the geometry of the instrument on the pitches and ease of playing of notes played on the instrument. Importantly, it will allow museum curators to determine tunings and (uncompensated) temperaments of historic instruments that cannot readily be played.Read moreRead less
Ultrasound for control of cyanobacteria. Blue-green algae, also known as cyanobacteria, forms in drinking water supplies in Australia and can cause water-quality problems. Current methods to treat blue-green algae involve the use of Copper Sulphate, which is not an environmentally friendly compound. A potential alternative environmentally friendly water-treatment method involves the use of ultrasound to disrupt the cyanobacteria. The aim of this project is to determine the physical properties of ....Ultrasound for control of cyanobacteria. Blue-green algae, also known as cyanobacteria, forms in drinking water supplies in Australia and can cause water-quality problems. Current methods to treat blue-green algae involve the use of Copper Sulphate, which is not an environmentally friendly compound. A potential alternative environmentally friendly water-treatment method involves the use of ultrasound to disrupt the cyanobacteria. The aim of this project is to determine the physical properties of the cyanobacteria when excited with ultrasound for the purpose of finding an efficient method to treat large volumes of water.

INTEGRATED PASSIVE AND ACTIVE CONTROL OF HUMMING NOISE FROM KCGM’S HAUL TRUCKS. This project aims to resolve an environmental noise issue caused by the humming noise of Kalgoorlie Consolidated Gold Mines haul trucks in the areas of Kalgoorlie, Boulder, and Williamstown. This solution utilises integrated passive and active control systems to attenuate the frequency components of humming noise from a truck’s exhaust and engine. A novel aspect of this technique is the use of passive micro-perforate ....INTEGRATED PASSIVE AND ACTIVE CONTROL OF HUMMING NOISE FROM KCGM’S HAUL TRUCKS. This project aims to resolve an environmental noise issue caused by the humming noise of Kalgoorlie Consolidated Gold Mines haul trucks in the areas of Kalgoorlie, Boulder, and Williamstown. This solution utilises integrated passive and active control systems to attenuate the frequency components of humming noise from a truck’s exhaust and engine. A novel aspect of this technique is the use of passive micro-perforated structures to provide the necessary sound absorption capability and to alter the sound propagation and radiation properties of the truck exhaust and engine, and increase the effectiveness of active control.Read moreRead less
Vocal resonances in speech: rapid, precise measurements of how tract resonances vary with time, with applications to speech and language training. This project will track dynamically with significant precision the resonances of the vocal tract which produce much of the phonetic information in speech and important features of accent. The information and technology developed will be useful for speech science, benefiting speech synthesis, speech training and language acquisition.
