In Australia, 40%(50,797) of all deaths each year are related to heart disease and accounted for 12% (A$4Billion) of total recurrent health expenditure. This innovative research aims at developing a single biventricular assist device (BVAD) driven by a magnetically suspended double-sided centrifugal pump impeller. Current techniques require two implantable devices, thus preventing smaller patients from access to BVAD technology. The expected outcomes will be a significantly small and compact device and provide an alternative to open-heart transplantation, thus helping to alleviate the demand on donor hearts, as well as the strain on the Australian Heath Care System caused by cardiovascular disease.Read moreRead less

Rapid growth in residential air conditioning (AC) ownership will potentially undermine national energy efficiency and greenhouse reduction targets. Furthermore, residential AC is placing a strain on the national electricity system, especially during heat waves when electricity demand peaks. These AC-driven peak loads occur occasionally each summer, but increasing grid capacity to meet them represents a grossly inefficient infrastructure investment. This project will generate Australia's most comprehensive data set on exactly how, when, where, and why residential AC systems are being used. The outcomes will provide a solid platform on which national electricity demand management and AC greenhouse-gas mitigation strategies can be designed.Read moreRead less
The development of new techniques for partial discharge monitoring and location in high voltage underground power cables. Increased utilization factors have caused a significant increase in the loading of high voltage distribution cables. This increased loading subjects cable insulation to increased stress which can degrade the insulation, cause cable failure and power loss to consumers. On-line cable insulation monitoring is required and partial discharge monitoring in cables provides a viable ....The development of new techniques for partial discharge monitoring and location in high voltage underground power cables. Increased utilization factors have caused a significant increase in the loading of high voltage distribution cables. This increased loading subjects cable insulation to increased stress which can degrade the insulation, cause cable failure and power loss to consumers. On-line cable insulation monitoring is required and partial discharge monitoring in cables provides a viable technique, but technical problems have prevented its application in on-line operation.
This project will develop techniques for such on-line monitoring. High frequency electrical sensors will be used to reduce interference and improve signal levels. Both a coarse alarm and a higher sensitivity monitor will be developed.

Traditional refrigeration essentially utilises CFC-refrigerants which are potent atmospheric pollutants causing widespread ecological damage. Devoid of such adversities, electronic heat pumping mechanism of thermoelectric principle offers a practical ?CFC-free? alternative for conventional cooling methods. While the current thermoelectric technology adequately meets light cooling demand, its potential for heavy-duty refrigeration is critically undermined by ill-developed methods for dissipating heat from thermoelectric modules to coolants, and remains grossly under-utilised. The proposed work will devise novel heat transfer techniques for raising thermoelectric cooling thresholds to suit large heat loads and develop a thermally enhanced micro-scale heat exchanger for application in commercial thermoelectric refrigeration.Read moreRead less
