The principal aim of this collaborative program between Australian and Japanese research teams is to tackle the complex issue of using active noise control systems focussing "zones of quiet" at passengers in aircraft and motor vehicles. The work has important implications for increased comfort of air travel and a safer environment for drivers of heavy vehicles. The outcomes will be the development of "smart skins" for application to aircraft and vehicle cabin interiors to actively control of interior noise. This will be achieved by combining the Japanese team's "structural wavenumber sensors" and the Adelaide team's "virtual microphones".Read moreRead less
Virtual acoustic sensors for active noise control systems. Traditional active noise control systems achieve the greatest noise reduction at the microphone error sensor(s). It is often desirable to achieve the maximum noise reduction remote from such sensors. Virtual sensing technology, the focus of this application, has the promise to replace traditional microphone sensing by projecting the zone of quiet away from the sensor microphones and directly into the ear of the user of the active noise c ....Virtual acoustic sensors for active noise control systems. Traditional active noise control systems achieve the greatest noise reduction at the microphone error sensor(s). It is often desirable to achieve the maximum noise reduction remote from such sensors. Virtual sensing technology, the focus of this application, has the promise to replace traditional microphone sensing by projecting the zone of quiet away from the sensor microphones and directly into the ear of the user of the active noise control system. This will revolutionise the sensing used in active noise control systems, and in doing so allow the realisation of active noise control in applications that have previously been infeasible.Read moreRead less

WAVE TRAPPING BARRIERS. Traditional noise barriers have poor performance when installed as parallel barriers in front of noise sources with large reflection surfaces. This is because that the reflected noise from the far side barrier or from the source surfaces contributes significantly to the noise level at the receiver location. This project involves the investigation of a novel barrier, the wave trapping barrier (WTB), which is capable of retaining the noise between the source and the barrier ....WAVE TRAPPING BARRIERS. Traditional noise barriers have poor performance when installed as parallel barriers in front of noise sources with large reflection surfaces. This is because that the reflected noise from the far side barrier or from the source surfaces contributes significantly to the noise level at the receiver location. This project involves the investigation of a novel barrier, the wave trapping barrier (WTB), which is capable of retaining the noise between the source and the barrier and to provide maximum sound absorption at the frequencies of concern, and thus to minimize the contribution due to the reflection. The aim is to develop a theoretical and experimental model for the physical understanding and optimal design of the WTB. Outcomes include a new generation of noise barriers that are potentially light-weighted, fiberless and with higher insertion loss.Read moreRead less
Analysing and Generating Fault-Tolerant Real-Time Systems. Safety-critical real-time systems are being deployed increasingly in diverse areas such as controlling critical infrastructure like transportation (e.g., railway signalling) as well as in defence applications (e.g., fly-by-wire).

Noise and vibration of vehicles is an important consideration for both performance efficiency and passenger comfort. Gear noise is a significant contributor to NVH of vehicles. Gear transmission error is recognised as the main source of gear drive vibration. This proposal involves the prediction and measurement of gear transmission error of a rear axle differential. A second important component is to investigate the effect of various vehicle parameters and operating conditions such as speed, load and power on the noise produced for a given TE. The successful outcomes will result in great economic benefit to Australia's automotive and manufacturing industry.Read moreRead less
Verified Emulation of Legacy Mission Computer Systems. Processor obsolescence is a serious maintenance problem for long-lived computer control systems in military aircraft and other critical applications. A promising solution is to interpose an emulator program between the original "legacy" software and a replacement processor. Unfortunately, no techniques exist for accurately verifying that this procedure preserves the original system's functional and timing behaviour. A particular challenge ....Verified Emulation of Legacy Mission Computer Systems. Processor obsolescence is a serious maintenance problem for long-lived computer control systems in military aircraft and other critical applications. A promising solution is to interpose an emulator program between the original "legacy" software and a replacement processor. Unfortunately, no techniques exist for accurately verifying that this procedure preserves the original system's functional and timing behaviour. A particular challenge is that processor emulations involve both legacy code and new subroutines, written in different programming languages. This project will enable verification of safety and mission-critical emulated systems by devising a multilingual modelling and reasoning formalism, based on program refinement theory.Read moreRead less
