Understanding mud pumping in heavy haul railroads. This project aims to examine the factors that cause mud pumping and evaluate the effectiveness of sub-surface drainage to prevent rail track instability. Fast heavy haul operations (such as loads used in mining and agriculture) impart repeated loads on the natural formation that can result in mud pumping. If the build-up of water pressure becomes excessive this can cause track failure. Through an experimental program and field study, the mechani ....Understanding mud pumping in heavy haul railroads. This project aims to examine the factors that cause mud pumping and evaluate the effectiveness of sub-surface drainage to prevent rail track instability. Fast heavy haul operations (such as loads used in mining and agriculture) impart repeated loads on the natural formation that can result in mud pumping. If the build-up of water pressure becomes excessive this can cause track failure. Through an experimental program and field study, the mechanisms of mud pumping, incorporating train loads and frequencies, will be studied, and the role of vertically installed drains will be quantified for improved practical design. The project aims to contribute to improved track longevity and reduced maintenance costs, with a corresponding boost in rail productivity.Read moreRead less
Mitigating the Severity of Level Crossing Accidents and Derailments. Ongoing increases in the number of level crossings and heavy road vehicles cause more frequent and severe level crossing accidents and derailments. Despite the use of active warning systems, each year, on average, 100 level crossing accidents occur in Australia. With a view to mitigating these crashes, this research aims to formulate theories for reduction in crash energy and effective wheel constraints to prevent derailment by ....Mitigating the Severity of Level Crossing Accidents and Derailments. Ongoing increases in the number of level crossings and heavy road vehicles cause more frequent and severe level crossing accidents and derailments. Despite the use of active warning systems, each year, on average, 100 level crossing accidents occur in Australia. With a view to mitigating these crashes, this research aims to formulate theories for reduction in crash energy and effective wheel constraints to prevent derailment by modifying the levels of road and rail crossings and providing guard rails in the recesses of these modified level crossings. The theories are intended be developed using nonlinear dynamic computational methods and laboratory experiments. The outcomes are expected to enable reduction in the severity of level crossing accidents and hence save lives and costs of derailment.Read moreRead less
A silicon-compatible light source on a silicon-on-insulator platform. Silicon is emerging as an important photonic material owing to the cheap processing methods developed for electronics. This project aims to capture key technology for integrating photonic components onto silicon. It can bring social and commercial benefits to Australia such as high-level research as well as opportunities for commercialisation.
Erosion of embankment dams and dam spillways. In excess of $250M is spent annually to maintain, upgrade, improve safety and monitor performance of Australian dams. Improved methods for assessing both spillway and internal erosion, the cause of 50 per cent of embankment dam failures and incidents requiring repairs, will be developed, maximising dam safety and minimising maintenance expenditure.

Summary
Mission archaeology and colonial encounters in Southern Vanuatu. The remains of Christian missions in southern Vanuatu are important heritage sites for local communities, and for their place in world history as part of one of the final frontiers of European colonialism. This project explores these sites to produce a new picture of everyday life that includes the perspectives of missionaries and native people.

Universal optical transmitter for rapid prototyping and system emulation: This Project proposes an integrated, multi-user facility for the generation of extremely wide-bandwidth optical communication signals that will help to dramatically improve the data-handling capability of optical fibres and improve the energy efficiency of optical communication networks. The project will modulate the input of an advanced optical transmitter with multi-level, multi-phase signals at multi-Gb/s rates to generate 'higher-order' modulation formats at multi- terra bits per second rates including orthogonal frequency-division multiplexing (OFDM), Nyquist-wavelength-division multiplexing (WDM), regular WDM and Optical Time-Division Multiplexing (OTDM). With this transmitter the project will investigate advanced optical communications concepts including 'constellations' of phase and intensity, limitations of nonlinearity in optical fibres, signal regeneration, and all-optical routing.Read moreRead less
Modelling and distributed control of large infrastructure networks. The main outcome of this project will be the capability to study systematically basic questions on the operation of large infrastructure systems. Methodologies for control of larger systems and security issues will be developed. Application of the techniques to several applications areas will include power grids and traffic networks.
