DEVELOPING SCIENTIFIC BASIS FOR THE RAPID DETECTION SYSTEM OF DIESEL VEHICLES WITH HIGH LEVEL OF EXHAUST EMISSIONS. Diesel vehicle exhaust is a significant source of air pollution leading to major human health problems. However, only a small fraction of vehicles with high exhaust emissions cause the majority of this pollution. Initially, this research will develop a model of dispersion of pollutants into the environment immediately after emission.

Diesel vehicle exhaust is a significant source of air pollution leading to major human health problems. However, only a small fraction of vehicles with high exhaust emissions cause the majority of this pollution. Initially, this research will develop a model of dispersion of pollutants into the environment immediately after emission. This model will be the scientific foundation for the development of an efficient and economical rapid detection system for those vehicles with high exhaust emissions. The major outcome is to improve air quality and lower the occurrence/severity of airborne pollution induced health effects.Read moreRead less

Over the coming years many millions of dollars will be spent on upgrading deteriorated pipeline infrastructure that is part of water distribution systems all over Australia. Determining the condition of buried pipes is very difficult and expensive. This research will solve that problem. We will develop powerful numerical methods for non-invasive pipe condition assessment. Small controlled transients will be input by a specially designed signal generation device that can determine the condition of the inside of the pipe. These new techniques will be cost-effective, accurate and able to cover very long distances of pipe. Water authorities will then be able to quickly decide which sections of pipe require further investigation.Read moreRead less
Micro-reflections for pipe condition assessment in water networks. Maintaining highly reliable water supply pipeline infrastructure for cities, towns and in rural Australia is extremely important. Our research will develop new non-invasive condition assessment techniques. Transient events will be used to create pressure waves that travel up and down a pipe.

Maintaining highly reliable water supply pipeline infrastructure for cities, towns and in rural Australia is extremely important. Our research will develop new non-invasive condition assessment techniques. Transient events will be used to create pressure waves that travel up and down a pipe. Sophisticated analysis of the micro-reflections in the measured pressure traces will be the heart of the new techniques. Water utility managers will be able to make a detailed assessment of the interior pipe wall to determine if significant corrosion or deterioration of the cement mortar lining has occurred. Rehabilitation strategies can then be determined. These new techniques will replace camera inspections that are extremely invasive and expensive.Read moreRead less
