Clinical Measurements of Refractive Index of Biological and Human Breast TissueMigara Alles School of Electrical, Electronic and Computer Engineering AION Diagnostics
Refractive index of biological tissue has been known to be a very good indication of tissue state. It can vary according to tissue hydration, calcification and age. This project aims to determine whether the refractive tissue of human breat tissue can be used as a diagnosing factor of cancer. Optical Coherance Tomography was used is an imaging technique to measure the refactive index of homogeneous and hetrogeneous biological tissue and non-biological media using the 'displaced relector' method. A key aspect of the process of measuring involved evaluation the accuracy of the testing system before measuring breat tissue. Results thus far haave idicated that tissue handleing procedures may need to be altered before breast tissue is measured.

Traditionally groundwater and surface water have been managed as separate water resources. However, in many regions they are hydraulically connected and the abstraction from one can influence the other. There is an increasing body of knowledge recognising the significant implications of ground water surface water interactions. Similarly, there are an increasing number of methods being developed to assess these interactions. Throughout Australia the Methodology is still in the developmetal stage with a growing number of methods to choose from, selecting the most suitable one is a challenge. Seven methods were compared for investigating groundwater surface water interactions in the Brunswick River. These included hydrogeological mapping, hydrograph analysis, temperature studies, seepage measurements, a salinity survey, field obervations and water budgeting. The suitability, accuracy and results of each method were compared.Top The Government Employees' Housing Authority (GEHA)1965-2006 Danielle Faulkner School of History The Goverment Employees' Housing Authority
Enacted by the Government Employees' Housing Act of 1964 (the Act) the Goverment Employees' Housing Authority ( GEHA) was proclaimed on the 2nd August 1965. For the following 42 years, GEHA continued to operate under its own legislation. In 2005 its fourtieth year, GEHA provided accomodation for 60 Goverment Agencies in over 250 locations through out regional Western Australia. What were the factors leasing to the formation of GEHA and how has the Authority evolved over the past forty-two years?Top Modelling of Test Data from Baandee Lakes Bridge Terry Arapis School of Civil & Resource Engineering Main Roads WA
Many bridges in WA designed in the 1960s and 1970s have been deemed structually deficient in punching shear under the current AustRoads Bridge Design Code (AS5100). However results from destructive testing of the Baandee Lakes Bridge No 1049 has found that current analysis techniques described in the code are conservative and so do not represent the acutal capasity of the bridge. This paper will discuss how the incorporation of soil-structure interaction along with current analysis techniques can improve the calculation of a brdiges structual capacity.Top Breakability of Various Timber Species Peter Chiang School of Mechanical Engineering Main Roads Western Australia
Roadside accidents where a car crashes into a tree can lead to serious injury or death for its occupants. One way of addressing this problem is to limit the size of trees that are within close proximity to the road so that only those that will breakway are kept. The project aims to investigate what are limiting sizes for breakability are for various native Western Australian species.Top Community Water Supply in East Timor Vaughn Grey School of Mechanical Engineering Engineers Without Borders Australia
Most East Timorese communities do not have access to adequate improved drinking water and sanitation practices. Attempts to address these shortfalls are being made by community water supply (CWS) projects being carried out across East Timor. This project is investigating the factors that surround a successful CWS, and ways in which success can be improved. Particular focus is made to the selection of appropriate techniques and technologies to be emplyed in a CWS, and the method in which to choose them.Top Feasibility Study of Alternative Gas Turbine Fuel for Offshore Power Generation Jerry Yuning Guo School of Mechanical Engineering Woodside Energy Ltd.
Offshore platform power generation is an essential part of oil and gas operations. Due to the strict fuel requirements set by gas turbine manufacters, power generation can be quite a costley business for operators. This cost increases drastically when there is insufficient gas fuel to power the turbines and expensive refined diesel is required to keep the operations running. Although it is also possible to run the turbine on alternative fuel sources such as the crude oil produced from the operation, the higher level of contaminants can have a detrimental effect on both the reliability and the operation life of the turbine. This paper looks at the alternative fuel sources available for offshore platforms, experiences with the running of alternative fuels, and discusses their feasibility.Top Road Pavement Condition Modelling Sang Soo Lim School of Civil and Resource Engineering Main Roads WA
There are many factors contributing to road users' discomfort - pavement roughness, rutting and its strength. Brand new pavement provides satisfactory level of comfort, however without efficient maintence plan, they deteriorate below required level of service in short amount of time. Most road users experience discomfort travelling on poorly maintained road pavement. It is the MRWA's job to provide quality service to road users as a government agency. MRWA uses sets of mathmatical expressions to predict deterioration of the pavement, triggering maintenances and its effects. Effects of various pavements treatments play an important role in planning efficient maintenance programme for the life cycle of a pavement. This study aims to improve mathmatical expressions used to predict treatment effects, using the maintenance data collected over the past few years. Top Effluent Reduction and CIP Efficiency in Dairy Processing Teresa Lui Yuen School of Environmental Systems Engineering Challenge Australian Dairy Pty Ltd
The major environmental problems associated with the dairy industry are high water consumption and discharge of wastewater with a high organic loading. This is due to the frequent cleaning process eqipment required to maintain strict hygiene standards. This paper presents a waste assessment conducted at Challenge Australian Dairy, and provides recommendations for reducing the effluent loading and the volume of wastewater produced at their Capel factory.Top Further Vibration Modelling of Beam/Slab Scale Model Benny Man School of Civil and Resourse Engineering Main Roads WA
A large number of bridges in Western Australia were constructed in the early 1960s and 1970s and many of them currently do not meet the requirements of current standards. This is because of updates in codes, increase in traffic loads, flooding of regions and deterioration of the bridge structure itself. In some of these bridges, the shear connectors appear inadequate to provide shear transfer from the deck of the bridge to the supporting girders under service loads. Therefore there is a need to investigate non-destructive strategies for repair/strengthening and to evaluate their effectiveness in improving the capasity of the existing bridge superstructure. Top Water Quality Assessment and Treatment in a Developing Community : Tangkae, East Timor Heidi Michael School of Environmental Systems Engineering Engineers Without Borders
In conjunction with water supply and sanitation studies, this study entails a detailed assessment of current water sources for the village of Tangkae, Dili District, East Timor. Focusing on water usages and the quality of water sources, cultural perspectives of water are also taken into consideration. With a population of two hundred and sixty four people the water sources used to supply the village with water for drinking, cooking, washing and cleaning are of difficult and distant access. Preliminary investigations and analysis indicate these water sources are microbiologically contaminated and highly turbid. To ensure sustainable solutions are implemented a multiple barrier approach is recommended, consisting of protection of the water source, appropriate level of treatment, safe water storage and sound hygiene and sanitation practices. A principal component of this project is building relations, exchanging information and endeavouring to empower various stakeholder parties to improve the opportunities available to them. The investigations from this study will provide recommendations for the community in question to use as a guide for implementation of improved waster supply and treatment systems.Top Investigation of Debutaniser Reconfiguration on the Northern Endeavour FPSO Ben Morley School of Oil & Gas Engineering Woodside Energy LTD

The Northern Endeavour is located in the Timor Sea and services the Laminaria and Corallina fields which are now in decline. The study specifically investigates options for cost minimisation for low production rates extending to end of field life. Upon implementation, the modifications identified in the study are expected to lead to a significant reduction in operational expenditure.Top Representation of Vulnerability on Submarine Tactical Displays Sena Pratama School of Mechanical Engineering and School of Electrical & Electronics Engineering DSTO
Defense Science and Technology Organisation (DSTO) is currently developing protypes of Tactical and Command displays. These prototypes will be used to convey to command the situation of the submarine and promote command team confidence that their understanding of the situation is sound. One of these prototypes is the Command Tatical Display. A major part of the displaying information to command is the need to be aware of the submarine's vulnerability, that is, factors that impact its safety. The submarine has a suite of sensors that can be used to determine its possible vulerability. The aim of this project is to invetigate and develop prototype(s) to display the submarines's vulnerability using simulated data from the submarine sensors, as layer/s on the Command Tactical Picture prototype. These display prototypes will be implemented and assessed by submarine operators and commanders.Top Identification of Heat Stress and Associated Heat Strain. Caused by Temperature related Working Conditions Suzanne Rice School of Biomedical and Chemical Science Pilbara Iron
All industrial operations introduce potential risks which may affect health and safety if adequate precautions are not taken. Heat stress is a well known contributing factor in underground mining primarily due to the high work activity demand under hot/wet environmental conditions. Surface mines in hot/dry conditions are also potentially at high risk, however there have been relatively few investigations into the occurance and assessment of heat stress here. This study therefore aimed to assess a populace identified by Rio Tinto's surface mine operation in the hot/dry Pilbara region of WA where general working conditions present high risk to heat stress. As a direct result, Occupational Health and Safety standards were determined to have adequate physiological limits set for individuals working in this unique work environment. In particular, that individual scheduled drinking routines and allowance for self-paced work were sufficient to offset the adverse effects of heat strain and associated dehydration, irrespective of the additional insulating effects of wearing personal protective equipment. Interestingly, the comparison period in winter highlighted the importance of continued rehydration and good sleep quality on ones risk to dehydrate and perception of fatigue, respectively.Top Develop and Test Alternative Conveyor Belt Cleaning Systems Paul Schubert School of Mechanical Engineering BHP Billiton Iron Ore
This project aims to investigate, develop and test alternative conveyor belt cleaning systems to improve material handling operations at BHP Billiton Ore Port Hedland. Most of the material that is transported on a conveyor is discharged at the head pulley, however a small proportion clings to the return belt resulting in the potential for spillage along the return length of the conveyor. The cost of this wasted product, damage to conveyor components and costs associated with handling this spillage are significant not to mention the environmental impact. It is for these reasons that belt cleaning has been focused on over the past few decades and extensive research into the integrity and effectiveness of belt cleaning equipment is beneficial to any materials handling operation.Top Moving to a Condition Based Maintenance Regime Scott White School of Mechanical Engineering DSTO
This paper presents a framework for assessing the quality of data for implementation of a Condition Based Maintenance (CBM) program. The framework includes (1) a methodolgy for conducting a data audit to determine whether the data is of adequate quality for a CBM program and (2) a process based on Root Cause Analysis (RCA) to determine the best course of action if the data quality is unacceptable. This framework has been applied to the oil analysis and data collection program run by the Royal Australian Navy's ANZAV Systems Programs Office (SPO).Top Evaluation of a Virtual Multiphase Flow Meter Jian-Ning Wong School of Oil & Gas Engineering Woodside Energy Ltd
Accurate muliphase flow metering is essential to the operation of a production well. The convential means of multiphase flow metering, well testing and muliphase flow meters are very costly. An alternative method of metering known as virtual muliphase flow metering, which uses software systems to estimate production flow rates, has recently emerged. This paper discusses the development of a virtual muliphase flow meter for a single well system. Software models of the flowline system and the choke well will be calibrated to historical well test data. These calibrated models will be used to infer oil, water and gas flow rates from measured pressures thus acting ad a virtual muliphase flow meter.Top Evaporative Air Conditioner Bushfire Ember Protective Screen Jonathan Ho School of Mechanical Engineering FESA of WA
It is not uncommon for houses with evaporative air conditioners situated near bush-land areas to catch fire during a bushfire due to embers (or firebrands) carried through the air. Embers are buring combustible materials which are carried ahead of a bushfire by the wind and fire convection currents. Many homes have been burnt down due to fires starting from an "ember attack" on evaporative air conditioners. This is where embers get carried through the air and into the cooling systems, igniting the filter pads. Once the air conditioner catches fire it tends to fall through the roof into homes and can cause the whole house to catch fire. The filter pads in an evaporative air conditioner are generally made of wood fibres and so are flammable. Although there has been some work into low-combustible filter pads, the build up of dust and pollen would always be flammable. Furthermore, to date Australian Standards have not addressed non-flammable pads in their regulations. This study aims to use and ember screen to block off dangerous embers from reaching the filter pads without inhibiting the effective operation of the air conditioner.
FEA Verification of the Shock And Vibration Response of Collins Class Submarine Equipment Racks
School of Mechanical Engineering
Raytheon Australia Pty Ltd
Raytheon Australia Pty Ltd has started a number of development projects to design equipment racks for electronic equipment on the Collins Class Submarines. These new designs will be created in ProEngineer and modelled in the FEA package ProMechanica with the goal of reducing the need for expensive prototype testing. This project is an initial investigation of the modelling capability fo ProMechanica for shock and vibration. The project follows a number of stages: the design of a test component that resembles an equipment rack; creation of a FEA model of this component on ProMechanica; conducting physical shock and vibration testing on the component; running simulations on the FEA model to mirror the physical shock and vibration testing; and finally tuning the FEA model until the software simulation results agree with the testing results. Early comparisons between simulations and theoretical calculations show a good reprentation of theoretical results in the simulations.
Vessel Classification from Periscope Data
School of Mechanical Engineering
Raytheon Australia Pty Ltd
In this paper we present a system for automatically recognising ships from periscope image data. The system is designed to be robust to noise as well as incomplete data in both the ship database and the image, while using features that may be extracted from and image reliably and relatively easily. The proposed system makes use of two heuristics involving vertical features (such as masts), and binary moment tables. A random ship generator has been developed to provide data on which to test the system, although tests of the system are not yet complete. We explain in detail our evaluation methodology and argue that it may provide a convincing proff-of-concept once tests are complete.
