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

In recent years, incidents of fire flashover have caused considerable destruction to property and the loss of life. Fire prediction and understanding is an area of significance to both the Australian public and the firefighting profession. The NSW Fire Brigade has recently introduced Compartment Fire Behaviour Training (CFBT). To extend this scheme, a database of configurations will be developed using computational modelling, allowing firefighters the ability to experience virtually different situations. Detailed experimental studies will be conducted to validate the numerical model. This database will have use and significance beyond Australia and successful implementation promises reductions in the loss of life and property.Read moreRead less
Experimental and numerical study of sprinklers for improved fire safety. Fire sprinklers are a common method for extinguishing fires. Current lack of detailed knowledge about sprinklers can lead to conservative design and excessive cost, often limiting the installation of these proven life-saving devices.

The production of high quality medical products requires strict process control, which is especially important for products of microscopic dimensions such as the glass pipettes used for in vitro fertilization (IVF) procedures and other research applications. In this project, a tailored mechanical system capable of simultaneously deforming a fine glass pipette at two points of micro geometrical dimensions and different temperatures will be developed after accurately experimentally benchmarking and computationally simulating the process. The system will be able to accommodate different types of pipettes and significantly improve the productivity and quality of this micro process.Read moreRead less
Geotechnical characterisation of compacted ground based on passive ambient noise techniques. The proposed research will provide our local construction and mining industries with a much needed fast and low cost technology for geotechnical investigation of very large sites which is currently not available.

The proposed research will provide our local construction and mining industries with a much needed fast and low cost technology for geotechnical investigation of very large sites which is currently not available. The project will help steer Australia to the forefront of ambient noise research for geotechnical site investigation, in the characterisation of unsaturated compacted soil and in the determination of dynamic site characteristics which are required for seismic risk assessment. Two postgraduate students will benefit from this research by receiving research training at the highest level and it will also pave the way for exporting the technology developed overseas, particularly to our near neighbours in Asia and the Pacific.

This proposed project combines the expertise and disciplines of residential construction, structural dynamics and blasting technology. The ultimate aim of the project is to develop a rational methodology for assessing the damage potential of ground vibration resulting from blasting on typical Australian residential structures. The project involves field blast vibration measurements, static and dynamic laboratory tests on structural sub-assemblages in a controlled environment, and comprehensive analytical modelling of both loading and response. The outcomes from this research will have direct application to the mining, insurance, construction and defence industries.Read moreRead less
PROBABILISTIC BRIDGE STRUCTURE CONDITION ASSESSMENT AND LOAD CARRYING CAPACITY PREDICTION. Bridge failures have occasionally been reported around the world. Condition assessment of bridges is vital to maintain their safety. It is difficult to assess quantitatively the deterioration and damage using traditional methods.

Bridge failures have occasionally been reported around the world. Condition assessment of bridges is vital to maintain their safety. It is difficult to assess quantitatively the deterioration and damage using traditional methods. Vibration-based methods are very sensitive to noise in vibration measurement and error in finite element modelling. This project will study the effects of measurement noises and finite element model errors on bridge condition assessment, and develop improved techniques for predicting load carrying capacities of bridges. The technique developed will be applied to Main Roads WA bridges, will also be applicable to the assessment of other types of structures.Read moreRead less

Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and ch ....Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and chemical interactions that occur between the particle and the oil-water interface, and develop a more efficient explosive that can be produced continuously on a commercial scale.Read moreRead less
