Productivity is seen as a main driver of economic growth and welfare improvements. Productivity indexes are used in a variety of policy contexts, in particular in determining the effectiveness (or otherwise) of government policies. Most industrialized countries have productivity accounts, but measurement problems persist and may even be more problematic in the future given an expansion in new goods and services. Improved productivity measurement and an improved understanding of its sources can inform aggregate and regional policy. The project includes collaboration with the Australian Bureau of Statistics and the Productivity Commission, with the participation of the Reserve Bank of Australia.Read moreRead less
Multilevel converters. Until recently the vast majority of power electronic applications have been to low voltage systems. However, developments in high voltage semiconductor switches in the last decade have generated significant activity in high voltage power electronic applications.

The project aims to develop computational models to predict emissions of nitric oxides and carbon monoxide from sugar-mill boilers burning bagasse. Bagasse combustion does not contribute to greenhouse gas emissions and clean and efficient combustion of this fuel has become very important for the sugar industry and for Australia. The project combines the opportunity of direct boiler measurements by SRI with the modelling expertise at the University to develop combustion-kinetics models for these species. The models will be incorporated into the previously developed computational fluid dynamics - combustion code of the furnace to give the capability of emission prediction as a function of burner operating conditions and fuel parameters.Read moreRead less
Cue Acquisition as a Mediator of Cognitive Skills Development. As the Australian workforce ages and there is a consequent reduction in the availability of experienced practitioners, organisations are going to be faced with the dilemma of placing relatively inexperienced staff in positions that were once occupied by experts. The result is a potential increase in the risks to critical infrastructure, such as electricity transmission. In this project, we expect to develop a set of principles that c ....Cue Acquisition as a Mediator of Cognitive Skills Development. As the Australian workforce ages and there is a consequent reduction in the availability of experienced practitioners, organisations are going to be faced with the dilemma of placing relatively inexperienced staff in positions that were once occupied by experts. The result is a potential increase in the risks to critical infrastructure, such as electricity transmission. In this project, we expect to develop a set of principles that can ensure that scenario based training is targeted to those aspects of the situation that are most important in maintaining the integrity of the system. The outcome is not only a safer system, but one that provides a structured approach to the acquisition of skills amongst employees.Read moreRead less
