Atlas-Based Segmentation Technique Incorporating Inter-Observer Delineation Uncertainty For Whole Breast, Lauren Bell, Jason Dowling, Elise M. Pogson, Peter E. Metcalfe, Lois C. Holloway
Faculty of Engineering and Information Sciences - Papers: Part A
Accurate, efficient auto-segmentation methods are essential for the clinical efficacy of adaptive radiotherapy delivered with highly conformal techniques. Current atlas based auto-segmentation techniques are adequate in this respect, however fail to account for inter-observer variation. An atlas-based segmentation method that incorporates inter-observer variation is proposed. This method is validated for a whole breast radiotherapy cohort containing 28 CT datasets with CTVs delineated by eight observers. To optimise atlas accuracy, the cohort was divided into categories by mean body mass index and laterality, with atlas' generated for each in a leave-one-out approach. Observer CTVs were merged and thresholded to generate an …
Retained Austenite: Transformation-Induced Plasticity, Elena V. Pereloma, Azdiar A. Gazder, Ilana B. Timokhina
Retained Austenite: Transformation-Induced Plasticity, Elena V. Pereloma, Azdiar A. Gazder, Ilana B. Timokhina
Faculty of Engineering and Information Sciences - Papers: Part A
The deformation-induced phase transformation of metastable austenite to martensite is accompanied by macroscopic plastic strain and results in significant work hardening and the delayed onset of necking. Steels that exhibit such transformation-induced plasticity (TRIP) effect possess high strength-ductility ratios and improved toughness. Since the stability of the retained austenite (RA) phase is the rate controlling mechanism for the TRIP effect, the factors affecting the chemical and mechanical stability of RA in CMnSi TRIP steels are discussed. It was suggested that chemical stability plays a more important role at low strains, whereas other factors become responsible for RA behavior at higher …
Impact Resistance Of Ultra-High Strength Concrete Beams With Frp Reinforcement, Alex M. Remennikov, Matthew Goldston, M Neaz Sheikh
Impact Resistance Of Ultra-High Strength Concrete Beams With Frp Reinforcement, Alex M. Remennikov, Matthew Goldston, M Neaz Sheikh
Faculty of Engineering and Information Sciences - Papers: Part A
Composite materials, including Fibre Reinforced Polymer (FRP) bars, have been used for decades in the structural and civil engineering sectors over traditional steel reinforcement. The main reasons for this are that FRP composites possess a number of advantages. They are non-corrosive, non-conductive, and lightweight and possess high longitudinal tensile strength. This paper presents the results of an experimental investigation into the effects of the use of glass FRP (GFRP) bars as internal reinforcement on the behaviour of concrete beams with high strength concrete (HSC) and ultra-high strength concrete (UHSC). Both static and dynamic (impact) behaviours of the beam have been …

Automatic Program Generation For Welding Robots From Cad, Nathan P. Larkin, Andrew Short, Zengxi Stephen Pan, Stephen Van Duin
Faculty of Engineering and Information Sciences - Papers: Part A
Industrial robotic automation is a key tool for manufacturing companies to achieve flexibility and low production costs. However, the cost associated with re-programming limits the economic viability for low production volumes. Automated Offline Programming is an approach that uses software algorithms to generate robot programs with little or no human effort. This contrasts with typical programming methods that require considerable human effort from highly skilled operators. This paper presents an Automated Offline Programming solution developed for a steel fabrication company and details the motion planning algorithms. It also describes a novel technique to decompose the welding path motion planning problem …
Recent Progress On Sampling Based Dynamic Motion Planning Algorithms, Andrew Short, Zengxi Stephen Pan, Nathan P. Larkin, Stephen Van Duin
Recent Progress On Sampling Based Dynamic Motion Planning Algorithms, Andrew Short, Zengxi Stephen Pan, Nathan P. Larkin, Stephen Van Duin
Faculty of Engineering and Information Sciences - Papers: Part A
This paper reviews recent developments extending sampling based motion planning algorithms to operate in dynamic environments. Sampling based planners provide an effective approach for solving high degree of freedom robot motion planning problems. The two most common algorithms are the Probabilistic Roadmap Method and Rapidly Exploring Random Trees. These standard techniques are well established, however they assume a fully known environment and generate paths ahead of time. For realistic applications a robot may be required to update its path in real-time as information is gained or obstacles change position. Variants of these standard algorithms designed for dynamic environments are categorically …

Characterisation And Resource Development Of Steel Plant By-Product Streams, Raymond Longbottom, Brian J. Monaghan, Guangqing Zhang, Sheng Chew, David J. Pinson
Faculty of Engineering and Information Sciences - Papers: Part A
The recycling of steel plant by-products is a critical issue that needs thorough assessment and development for the sustainability of the integrated steel plant, from both environmental and economical perspectives. Research is being undertaken in the Steel Research Hub that aims to realise the value of by-products to the Australian steel industry and minimise the amount of by-product going to long term stockpile. As the first step, dust from basic oxygen steelmaking (BOS), a major steel plant by-product stream, is being characterised so that its potential use on plant or elsewhere can be assessed and evaluated. BOS dust contains components …
On The Classical Solvability Of Near Field Reflector Problems, Jiakun Liu, Neil Trudinger
On The Classical Solvability Of Near Field Reflector Problems, Jiakun Liu, Neil Trudinger
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper we prove the existence of classical solutions to near field reflector problems, both for a point light source and for a parrallel light source, with planar recievers. These problems involve monge-Ampere type equations, subject to nonlinear oblique boundary conditions. Our approach builds on earlier work in the optimal transportation case by Trudinger and Wang and makes use of a recent extension of degree theory to oblique boundary conditioins by Li, Liu and Nguyen.

Hai, Frederic D.L Leusch, Jinguo Kang, William E. Price, Felicity Roddick, Saleh F. Magram, Long D. Nghiem
Laccase-Syringaldehyde-Mediated Degradation Of Trace Organic Contaminants In An Enzymatic Membrane Reactor: Removal Efficiency And Effluent Toxicity, Luong N. Nguyen, Jason P. Van De Merwe, Faisal I. Hai, Frederic D.L Leusch, Jinguo Kang, William E. Price, Felicity Roddick, Saleh F. Magram, Long D. Nghiem
Faculty of Engineering and Information Sciences - Papers: Part A
Redox-mediators such as syringaldehyde (SA) can improve laccase-catalyzed degradation of trace organic contaminants (TrOCs) but may increase effluent toxicity. The degradation performance of 14 phenolic and 17 non-phenolic TrOCs by a continuous flow enzymatic membrane reactor (EMR) at different TrOC and SA loadings was assessed. A specific emphasis was placed on the investigation of the toxicity of the enzyme (laccase), SA, TrOCs and the treated effluent. Batch tests demonstrated significant individual and interactive toxicity of the laccase and SA preparations. Reduced removal of resistant TrOCs by the EMR was observed for dosages over 50. μg/L. SA addition at a concentration …

Lubrication Characterisation Analysis Of Stainless Steel Foil During Micro Rolling, Haibo Xie, Kenichi Manabe, Tsuyoshi Furushima, Kazuo Tada, Zhengyi Jiang
Faculty of Engineering and Information Sciences - Papers: Part A
Physical parameters, such as microscopic and roughness, play important roles in microforming process due to an increasing ratio of surface to volume of the deformed material. The study on lubrication characterisation in microforming is getting more attractive to researchers because traditional models are not reliable in this scaled down process. In this study, the micro rolling deformation characterisation has been investigated on SUS 304 stainless steel considering lubricant effect and feature size effect. The foil thickness plays an important role in the tribological features of micro rolling. The evolutions of both oil film thickness and foil surface are analysed accordingly. …

Towards Organizing Smart Collaboration And Enhancing Teamwork Performance: A Ga-Supported System Oriented To Mobile Learning Through Cloud-Based Online Course, Geng Sun, Jun Shen
Faculty of Engineering and Information Sciences - Papers: Part A
At present, people’s learning styles become diverse, for which mobile learning is a significant trend that enables distributed learners to achieve collaborative learning and allows them to be engaged in virtual teams to work together. In this research, we develop a system to cope with the problem in current mobile learning circumstance, where learners in virtual teams generally lack proper communications, guidance and assistances between each other. Following the theory of Kolb team learning experience, we use our system, Teamwork as a Service (TaaS), to work in conjunction with cloud-based learning management systems. This system targets at organizing a series …
Constrained Ordination Analysis With Enrichment Of Bell-Shaped Response Functions, Yingjie Zhang, Olivier Thas
Constrained Ordination Analysis With Enrichment Of Bell-Shaped Response Functions, Yingjie Zhang, Olivier Thas
Faculty of Engineering and Information Sciences - Papers: Part A
Constrained ordination methods aims at finding an environmental gradient along which the species abundances are maximally separated. The species response functions, which describe the expected abundance as a function of the environmental score, are according to the ecological fundamental niche theory only meaningful if they are bell-shaped. Many classical model-based ordination methods, however, use quadratic regression models without imposing the bell-shape and thus allowing for meaningless U-shaped response functions. The analysis output (e.g. a biplot) may therefore be potentially misleading and the conclusions are prone to errors. In this paper we presenta log-likelihood ratio criterion with a penalisation term to …
The Effect Of Respiratory Induced Density Variations On Non-Tof Pet Quantitation In The Lung, Beverley F. Holman, Vesna Cuplov, Brian F. Hutton, Ashley M. Groves, Kris Thielemans
The Effect Of Respiratory Induced Density Variations On Non-Tof Pet Quantitation In The Lung, Beverley F. Holman, Vesna Cuplov, Brian F. Hutton, Ashley M. Groves, Kris Thielemans
Faculty of Engineering and Information Sciences - Papers: Part A
Accurate PET quantitation requires a matched attenuation map. Obtaining matched CT attenuation maps in the thorax is difficult due to the respiratory cycle which causes both motion and density changes. Unlike with motion, little attention has been given to the effects of density changes in the lung on PET quantitation. This work aims to explore the extent of the errors caused by pulmonary density attenuation map mismatch on dynamic and static parameter estimates. Dynamic XCAT phantoms were utilised using clinically relevant 18F-FDG and 18F-FMISO time activity curves for all organs within the thorax to estimate the expected parameter errors. The …
Planogram Compliance Checking Based On Detection Of Recurring Patterns, Song Liu, Wanqing Li, Stephen J. Davis, Christian H. Ritz, Hongda Tian
Planogram Compliance Checking Based On Detection Of Recurring Patterns, Song Liu, Wanqing Li, Stephen J. Davis, Christian H. Ritz, Hongda Tian
Faculty of Engineering and Information Sciences - Papers: Part A
In this article, the authors propose a novel method for automatic planogram compliance checking in retail chains that doesn't require product template images for training. Product layout is extracted from an input image by means of unsupervised recurring pattern detection and matched via graph matching, with the expected product layout specified by a planogram to measure the level of compliance. A divide-and-conquer strategy is employed to improve the speed. Specifically, the input image is divided into several regions based on the planogram. Recurring patterns are detected in each region, respectively, and then merged together to estimate the product layout.
Learning Network Storage Curriculum With Experimental Case Based On Embedded Systems, Qingguo Zhou, Jiong Wu, Ting Wu, Jun Shen, Rui Zhou
Learning Network Storage Curriculum With Experimental Case Based On Embedded Systems, Qingguo Zhou, Jiong Wu, Ting Wu, Jun Shen, Rui Zhou
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper, we present an experimental case for the course of "Network Storage and Security," which benefited from an improved learning outcome for our students. The newly designed experiments-based contents are merged into the current course to help students obtain practical experiences about network storage. The experiments aim to build a network storage system based on available resources instead of any specialized network storage equipment. Technically, students can learn general practical knowledge of network storage on iSCSI (a network storage protocol based on IP technology) and also the technologies of embedded system. Through the experimental case, we found that …

We introduce a new construction based on directed graphs. It provides a common generalization of the incidence rings and Munn semirings. Our main theorem describes all ideals of the largest possible weight in this construction. Several previous results can be obtained as corollaries to our new main theorem.
Topological Spaces Associated To Higher-Rank Graphs, Alexander Kumjian, David Pask, Aidan Sims, Michael F. Whittaker
Topological Spaces Associated To Higher-Rank Graphs, Alexander Kumjian, David Pask, Aidan Sims, Michael F. Whittaker
Faculty of Engineering and Information Sciences - Papers: Part A
We investigate which topological spaces can be constructed as topological realisations of higher-rank graphs. We describe equivalence relations on higher-rank graphs for which the quotient is again a higher-rank graph, and show that identifying isomorphic co-hereditary subgraphs in a disjoint union of two rank-k graphs gives rise to pullbacks of the associated C*-algebras. We describe a combinatorial version of the connected-sum operation and apply it to the rank-2-graph realisations of the four basic surfaces to deduce that every compact 2-manifold is the topological realisation of a rank-2 graph. We also show how to construct k-spheres and wedges of k-spheres as …

Transient Cfd Modelling Of Low-Temperature Spontaneous Heating Behaviour In Multiple Coal Stockpiles With Wind Forced Convection, Jian Zhang, Yuntao Liang, Ting X. Ren, Zhongwei Wang, Gongda Wang
Transient Cfd Modelling Of Low-Temperature Spontaneous Heating Behaviour In Multiple Coal Stockpiles With Wind Forced Convection, Jian Zhang, Yuntao Liang, Ting X. Ren, Zhongwei Wang, Gongda Wang
Faculty of Engineering and Information Sciences - Papers: Part A
Spontaneous heating of coal stockpile has long been a thermal dynamic hazard during coal storage, processing, and transport. A transient non-equilibrium thermal CFD model has been developed to study the low-temperature self-heating behaviour of coal in multiple stockpiles under different prevailing wind conditions. Modelling results from the initial steady wind flow simulation indicate that a wake region can be induced on the leeward side of each coal stockpile. Pressure coefficient drops when the wind stream encounters or leaves a stockpile and the pressure coefficient profiles of multiple stockpiles tend to have more resemblance with a wider spacing. The first stockpile …

Faculty of Engineering and Information Sciences - Papers: Part A
Coalwash (CW) is granular waste by-product that results from the operation of the local coal mining industry. The reuse and recycling of this material in earthwork construction project as landfill option, is attractive from both economic and environmental perspectives. This paper presents an experimental study on compacted CW material prepared at different relative compaction levels. First the basic materials index properties are described and the stress-dilatancy behaviour is examined through a series of drained triaxial compression tests. The experimental data suggests that the different relative compaction levels exhibit different stress strain behaviour but show some degree of similarity in terms …

Compressive Behavior Of Frp-Confined Concrete-Encased Steel Columns, Tao Yu, G Lin, Shi Shun Zhang
Faculty of Engineering and Information Sciences - Papers: Part A
FRP-confined concrete-encased steel I-section columns (FCSCs) are an emerging form of hybrid columns. An FCSC consists of an outer FRP tube, an encased steel section and a concrete infill. The FCSCs possess many advantages over conventional reinforced concrete columns, including the excellent corrosion resistance, excellent ductility and ease for construction. Existing studies on FCSCs, however, have been rather limited. This paper presents a combined experimental and theoretical study on the behavior of FCSCs under concentric and eccentric compression. The experimental program included the testing of a total of 14 specimens, with the main variables being the section configuration, the thickness …

Application Of Shock Mats In Rail Track Foundation Subjected To Dynamic Loads, Sinniah Navaratnarajah, Buddhima Indraratna, Sanjay Nimbalkar
Faculty of Engineering and Information Sciences - Papers: Part A
Rail track substructure (ballast, subballast and subgrade) is the most essential component of the railway system in view of track stability. The ballast is the largest component of the track substructure and it is the key load-bearing stratum packed with rock aggregates underneath and around the sleepers, thereby providing structural support against dynamic stresses caused by moving trains. However under large dynamic stresses exerted by heavy haul and high speed trains, the degradation of track substructure including ballast becomes significant. This in turn affects the track stability and creates frequent maintenance, thus increasing the life cycle cost of the rail …

Assessment Of Interface Shear Behaviour Of Sub-Ballast With Geosynthetics By Large-Scale Direct Shear Test, Mohammad Mahdi Biabani, Buddhima Indraratna, Sanjay Nimbalkar
Faculty of Engineering and Information Sciences - Papers: Part A
A series of large-scale direct shear test were conducted to study the interface shear strength of subballast reinforced with different types of geomembranes and geogrids. The impact of normal stress (σn), shearing rate (SR), relative density (DR) and open area (OA%) on the behaviour of granular material was investigated in unreinforced and reinforced condition. The results revealed that the performance of material was markedly influenced by σn and OA. The results also showed that geogrids provided a greater value of passive resistance owing to have transverse ribs, but the mobilised passive resistance became smaller with increase in OA. The triaxial …

Size Optimization Of A Magnetic System For Drug Delivery With Capsule Robots, Fredy Munoz, Gursel Alici, Weihua Li, Metin Sitti
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper, we present a methodology for the size optimization of an external magnetic system made of arc-shaped permanent magnets (ASMs). This magnetic system is able to remotely actuate a drug-release module embedded in a prototype of a capsule robot. The optimization of the magnetic system is carried out by using an accurate analytical model that is valid for any arbitrary dimensions of the ASMs. By using this analytical model, we perform parametric studies and conduct a statistical analysis [analysis of variance (ANOVA)] to investigate efficient ways to distribute the volume of the ASMs so that the dimensions and …

A Sensor Fault Detection Strategy For Air Handling Units Using Cluster Analysis, Rui Yan, Zhenjun Ma, Georgios Kokogiannakis, Yang Zhao
Faculty of Engineering and Information Sciences - Papers: Part A
Sensors are an essential component in the control systems of air handling units (AHUs). A biased sensor reading could result in inappropriate control and thereby increased energy consumption or unsatisfied indoor thermal comfort. This paper presents an unsupervised learning based strategy using cluster analysis for AHU sensor fault detection. The historical data recorded from sensors is first pre-processed to reduce the dimensions using principal component analysis (PCA). The clustering algorithmOrdering Points to Identify the Clustering Structure (OPTICS) is then employed to identify the spatial separated data groups (i.e. clusters),which possibly indicate the occurrence of sensor faults. The data points in …

Faculty of Engineering and Information Sciences - Papers: Part A
Silico-ferrites of calcium and aluminium (SFCA) are desirable phases in a high quality iron ore sinter product. The effects of sintering temperature, CaO/SiO2 ratio, sintering gas atmosphere and cooling procedure on the phase composition of sintered specimens from an industrial sinter blend were examined with focus on the formation of SFCA phases. The proportions of mineral phases in specimens sintered at 1 250-1 325°C were quantitatively examined using image analysis. SFCA can be formed at low temperatures by solid state reactions, the formation of which was enhanced by increasing temperature. Further increasing sintering temperature promoted the reduction of Fe3+ in …
