Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little ....Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little is known about the technology. This project will model the behaviour of rubber soil in order to introduce it as an environmentally sustainable, cost-effective and technically sound choice of geomaterial for both standard and non-standard geotechnical structures.Read moreRead less
Ultrasound for control of cyanobacteria. Blue-green algae, also known as cyanobacteria, forms in drinking water supplies in Australia and can cause water-quality problems. Current methods to treat blue-green algae involve the use of Copper Sulphate, which is not an environmentally friendly compound. A potential alternative environmentally friendly water-treatment method involves the use of ultrasound to disrupt the cyanobacteria. The aim of this project is to determine the physical properties of ....Ultrasound for control of cyanobacteria.

This research will further understanding of the mechanisms that generate individual differences in learning ability and will have applications for educational techniques and behavioural interventions.Read moreRead less
NEUTRALISING MINERAL REACTIONS IN ACID MINE DRAINAGE CONTROL. The project addresses the serious environmental problem of acid and toxic element release from iron sulfides in waste rock dumps and tailings storage in the mining industry. Long-term neutralising capacity, currently not tested in laboratory assessments, is available from the reaction of some silicate and aluminosilicate minerals. This potential has not been systematically tested or modelled. The research project aims to understand th ....NEUTRALISING MINERAL REACTIONS IN ACID MINE DRAINAGE CONTROL. The project addresses the serious environmental problem of acid and toxic element release from iron sulfides in waste rock dumps and tailings storage in the mining industry. Long-term neutralising capacity, currently not tested in laboratory assessments, is available from the reaction of some silicate and aluminosilicate minerals. This potential has not been systematically tested or modelled. The research project aims to understand the relative mechanisms and rates for long-term alleviation of acid production with mineral layered and blended combinations. Improved understanding will provide methodology for assessment and control of acid mine drainage.Read moreRead less
The Changing Role Of The Magistrates Court. Magistrates courts have far more contact with the community than any other court but have rarely been the subject of direct research. Recent changes include greater professional qualifications for magistrates and increased volume, complexity and seriousness of cases.

Magistrates courts have far more contact with the community than any other court but have rarely been the subject of direct research. Recent changes include greater professional qualifications for magistrates and increased volume, complexity and seriousness of cases. This project will survey the changing social/demographic characteristics of magistrates; analyse their daily work, especially increased judicial functions; and examine roles played by social service providers. It will produce a better understanding of magistrates courts, emphasising ideas of judicial independence and accountability, essential to ensuring high standards for the Australian legal system and its relation to the community.Read moreRead less
Developing a generative transformational theory of visual perception. This project will develop and test a generative, transformational computer model of visual perception, based on fractal encoding. This uses a powerful similarity metric to select transformations, that, when applied to image elements, generate a replica of the image. The model can detect and analyse structure in regular and semi-regular images, even when embedded in noise. This approach provides an explanation for several perce ....Developing a generative transformational theory of visual perception. This project will develop and test a generative, transformational computer model of visual perception, based on fractal encoding. This uses a powerful similarity metric to select transformations, that, when applied to image elements, generate a replica of the image. The model can detect and analyse structure in regular and semi-regular images, even when embedded in noise. This approach provides an explanation for several perceptual phenomena and illusions. It can reconcile opposed theories of perception and provide a unifying perspective on perception and cognition. Practical applications include the automatic recognition of objects in imagery and the detection of structure in complex data.Read moreRead less
Developing an integrative theoretical account of some basic mechanisms and limiting factors in human perception and cognition. The principal factors limiting cognitive performance are widely considered to be information processing speed, working memory capacity, and the effective control of cognitive processes. The proposed programme aims to develop and test a unifying theory relating these to two of the most basic achievements of the brain - discrimination and identification. This will help us ....Developing an integrative theoretical account of some basic mechanisms and limiting factors in human perception and cognition. The principal factors limiting cognitive performance are widely considered to be information processing speed, working memory capacity, and the effective control of cognitive processes. The proposed programme aims to develop and test a unifying theory relating these to two of the most basic achievements of the brain - discrimination and identification. This will help us to understand the underlying basis of differences and changes in cognitive performance. The outcomes have implications for the design, analysis and interpretation of studies of perception, judgement, memory and intelligence. The research also has applied relevance to neuropsychology, information handling and the design of system interfaces.Read moreRead less
How feedback can impair recognition judgments and undermine border security, criminal investigations, educational testing, and medical screening. If a customs officer learns that they have missed an explosive device while screening luggage, will this affect their judgment? In many scenarios, a person receives feedback about their recognition memory performance and has to try again without having another chance to study the material. Almost no research has examined the effects of feedback on reco ....How feedback can impair recognition judgments and undermine border security, criminal investigations, educational testing, and medical screening. If a customs officer learns that they have missed an explosive device while screening luggage, will this affect their judgment? In many scenarios, a person receives feedback about their recognition memory performance and has to try again without having another chance to study the material. Almost no research has examined the effects of feedback on recognition in the absence of opportunity for further study. This is problematic because many vitally important recognition decisions lack such opportunity. Using various scenarios (face recognition, security screening, multiple-choice testing, and medical screening) this project will demonstrate that feedback affects recognition performance differently depending on the nature of the recognition decision.Read moreRead less
Optimal strategies for collaborative visual search. The ability of individual operators to search for and detect targets is a weak link in many military, medical, and industrial operations. Teams of operators, however, can perform well even when individuals do not.

The ability of individual operators to search for and detect targets is a weak link in many military, medical, and industrial operations. Teams of operators, however, can perform well even when individuals do not. This project aims to investigate a promising new eye-tracking technique, gaze-linking, that helps searchers collaborate efficiently by allowing each to know where the other is looking. This research builds on mathematical models of information processing to identify strategies that optimise gaze-linked collaboration, and is expected to develop principles for training gaze-linked searchers. Gaze-linking offers a promising, and potentially economical, technique for improving human performance, increasing efficiency and safety in a variety of tasks.Read moreRead less
