Economic Operation Optimization Of Battery Energy Storage Systems In A Solar Rich Microgrid, Herath Pathiranage Asanga Priyankara Jayawardana, Massimo Fiorentini, Duane A. Robinson, Ashish P. Agalgaonkar

Faculty of Engineering and Information Sciences - Papers: Part B

The increasing trend of connecting local distributed generation units to the grid has unlocked new economic opportunities for owners. This is supported by the ongoing development of energy storage technologies, especially battery based systems. In practice, battery storage systems typically operate based on control algorithms where tariff structures and future generation and load profiles are not taken into account. This paper investigates the results of a case study for a microgrid using a proposed optimization model which minimizes cost by considering an import/export tariff structure. The effect of changing time resolution related to variations in demand and generation is examined, …

Adaptive Random Testing In Detecting Layout Faults Of Web Applications, Elmin Selay, Zhi Quan Zhou, Tsong Yueh Chen, Fei-Ching Kuo

Faculty of Engineering and Information Sciences - Papers: Part B

As part of a software testing process, output verification poses a challenge when the output is not numeric or textual, such as graphical. The industry practice of using human oracles (testers) to observe and verify the correctness of the actual results is both expensive and error-prone. In particular, this practice is usually unsustainable when developing web applications - the most popular software of our era. This is because web applications change frequently due to the fast-evolving requirements amid popular demand. To improve the cost effectiveness of browser output verification, in this study we design failure-based testing techniques and evaluate the …

A Cyclical Social Learning Strategy For Robust Convention Emergence, Yuchen Wang, Fenghui Ren, Minjie Zhang Jan 2018

A Cyclical Social Learning Strategy For Robust Convention Emergence, Yuchen Wang, Fenghui Ren, Minjie Zhang

Faculty of Engineering and Information Sciences - Papers: Part B

Social conventions have been used as an efficient mechanism to facilitate coordination among agents. Establishing a convention in a decentralised manner has attracted much attention in the literature. Existing techniques on convention emergence are not robust. These techniques may establish sub-conventions under particular network structures. The emergence of sub-conventions indicates that agents in a society fail to conform to a single convention. As a result, the coordination among these agents is negatively affected. In this paper, we propose a strategy to avoid sub-conventions under diverse network structures. The proposed strategy requires agents to only have local views. We prove that …

Clinical Impact Of Respiratory Motion Correction In Simultaneous Pet/Mr, Using A Joint Pet/Mr Predictive Motion Model, Richard Manber, Kris Thielemans, Brian F. Hutton, Simon Wan, Francesco Fraioli, Anna Barnes, Sebastien Ourselin, Simon R. Arridge, David Atkinson

Faculty of Engineering and Information Sciences - Papers: Part B

In Positron Emission Tomography (PET) imaging, patient motion due to respiration can lead to artefacts and blurring, in addition to quantification errors. The integration of PET imaging with Magnetic Resonance (MR) imaging in PET/MR scanners provides spatially aligned complementary clinical information, and allows the use of high spatial resolution and high contrast MR images to monitor and correct motion-corrupted PET data. We validate our PET respiratory motion correction methodology based on a joint PET-MR motion model, on a patient cohort, showing it can improve lesion detectability and quantitation, and reduce image artefacts. Methods: We apply our motion correction methodology on …

The Magneto-Thermoelectric Effect Of Graphene With Intra-Valley Scattering, Wenye Duan, Junfeng Liu, C Zhang, Zhongshui Ma Jan 2018

The Magneto-Thermoelectric Effect Of Graphene With Intra-Valley Scattering, Wenye Duan, Junfeng Liu, C Zhang, Zhongshui Ma

Faculty of Engineering and Information Sciences - Papers: Part B

We present a qualitative and quantitative study of the magneto-thermoelectric effect of graphene. In the limit of impurity scattering length being much longer than the lattice constant, the intra-valley scattering dominates the charge and thermal transport. The self-energy and the Green's functions are calculated in the self-consistent Born approximation. It is found that the longitudinal thermal conductivity splits into double peaks at high Landau levels and exhibits oscillations which are out of phase with the electric conductivity. The chemical potential-dependent electrical resistivity, the thermal conductivities, the Seebeck coefficient, and the Nernst coefficient are obtained. The results are in good agreement …

Reinhard, Vladimir Perevertaylo, Sarah Anderson, Chris Beltran, Naruhiro Matsufuji, Michael A. Jackson, Anatoly B. Rosenfeld

Faculty of Engineering and Information Sciences - Papers: Part B

Using the CMRP ‘bridge' μ+ probe, microdosimetric measurements were undertaken out-of-field using a therapeutic scanning proton pencil beam and in-field using a 12C ion therapy field. These measurements were undertaken at Mayo Clinic, Rochester, USA and at HIMAC, Chiba, Japan, respectively. For a typical proton field used in the treatment of deep-seated tumors, we observed dose-equivalent values ranging from 0.62 to 0.99 mSv/Gy at locations downstream of the distal edge. Lateral measurements at depths close to the entrance and along the SOBP plateau were found to reach maximum values of 3.1 mSv/Gy and 5.3 mSv/Gy at 10 mm from …

Experimental Study On Simultaneously Measuring Young's Modulus And Internal Fraction Using Self-Mixing System, Fei Xia, Bin Liu, Lingzhi Cao, Yanguang Yu, Jiangtao Xi, Qinghua Guo, Jun Tong Jan 2018

Experimental Study On Simultaneously Measuring Young's Modulus And Internal Fraction Using Self-Mixing System, Fei Xia, Bin Liu, Lingzhi Cao, Yanguang Yu, Jiangtao Xi, Qinghua Guo, Jun Tong

Faculty of Engineering and Information Sciences - Papers: Part B

Material parameters such as Young's modulus and internal friction are important for estimation of material performance. This paper presents an experimental study for measuring material related parameters using a selfmixing interferometric (SMI) configuration. An SMI system consists of a laser diode (LD), a lens and an external target to be measured. When a part of the lasing light back-reflected or back-scattered by the external target re-enters the LD internal cavity, both optical frequency and intensity of the lasing light can be modulated. This modulated laser intensity is often referred as SMI signal. Generally, the target related movement or its surface …

Influence Of System Bandwidth On Self-Mixing Signal, Bin Liu, Yuxi Ruan, Lingzhi Cao, Yanguang Yu, Jiangtao Xi, Qinghua Guo, Jun Tong Jan 2018

Influence Of System Bandwidth On Self-Mixing Signal, Bin Liu, Yuxi Ruan, Lingzhi Cao, Yanguang Yu, Jiangtao Xi, Qinghua Guo, Jun Tong

Faculty of Engineering and Information Sciences - Papers: Part B

Self-mixing interferometry (SMI) is a well-developed sensing technology. An SMI system can be described using a model derived from the well-known Lang and Kobayashi equations by setting the system operating in stable region. The features of an SMI signal are determined by the external optical feedback factor (denoted by C). Our recent work shows that when the factor C increases to a certain value, e.g. in moderate feedback regime with 1

Sonication-Enabled Rapid Production Of Stable Liquid Metal Nanoparticles Grafted With Poly(1- Octadecene-Alt-Maleic Anhydride) In Aqueous Solutions, Yiliang Lin, Jan Genzer, Weihua Li, Ruirui Qiao, Michael Dickey, Shiyang Tang Jan 2018

Sonication-Enabled Rapid Production Of Stable Liquid Metal Nanoparticles Grafted With Poly(1- Octadecene-Alt-Maleic Anhydride) In Aqueous Solutions, Yiliang Lin, Jan Genzer, Weihua Li, Ruirui Qiao, Michael Dickey, Shiyang Tang

Faculty of Engineering and Information Sciences - Papers: Part B

Gallium-based liquid metals are attractive due to their unique combination of metallic and fluidic properties. Liquid metal nanoparticles (LM NPs), produced readily using sonication, find use in soft electronics, drug delivery, and other applications. However, LM NPs in aqueous solutions tend to oxidize and precipitate over time, which hinders their utility in systems that require long-term stability. Here, we introduce a facile route to rapidly produce an aqueous suspension of stable LM NPs within five minutes. We accomplish this by dissolving poly(1-octadecene-alt-maleic anhydride) (POMA) in toluene and mixing with deionized water in the presence of a liquid metal (LM). Sonicating …

Reusable Flexible Concentric Electrodes Coated With A Conductive Graphene Ink For Electrotactile Stimulation, Benjamin Stephens-Fripp, Vitor Sencadas, Rahim Mutlu, Gursel Alici

Faculty of Engineering and Information Sciences - Papers: Part B

Electrotactile stimulation is a highly promising technique for providing sensory feedback information for prosthetics. To this aim, disposable electrodes which are predominantly used result in a high environmental and financial cost when used over a long period of time. In addition, disposable electrodes are limited in their size and configurations. This paper presents an alternative approach based on a 3D printed reusable flexible concentric electrode coated with a conductive graphene ink. Here, we have characterized the electrode and demonstrated its effective performance in electrotactile stimulation and sensory feedback for robotic prosthetic hands.

Challenges And Solutions Towards Natural Prefabricated Vertical Drains, Thanh Trung Nguyen, Buddhima Indraratna, Cholachat Rujikiatkamjorn

Faculty of Engineering and Information Sciences - Papers: Part B

In recent years, natural fibres such as jute and coir are emerging as a reasonable alternative to synthetic materials because they do not only have favourable engineering characteristics but also degrade biologically over time. Of promising applications of those environmentally friendly materials, natural prefabricated vertical drains (NPVDs) have received considerable attention, however their application is still limited. This paper summarises existing issues which are hampering these novel drains from a wider application, followed by studies carried out by the authors to overcome those limitations. Particularly this includes: (1) hydraulic properties of NPVDs considering macro and micro features; (2) modelling NPVDS …

Feasible Negotiation Procedures For Multiple Interdependent Negotiations, Lei Niu, Fenghui Ren, Minjie Zhang

Faculty of Engineering and Information Sciences - Papers: Part B

Within an agent society, agents utilise their knowledge differently to achieve their individual or joint goals. Agent negotiation provides an effective solution to help agents reach agreements on their future behaviour in the society to guarantee their goals can be achieved successfully. Agents may need to conduct Multiple Interdependent Negotiations (MIN) with different opponents and for different purposes, in order to achieve a goal. By considering the complexity of negotiation environments, interdependencies, opponents and issues in the agent society, conducting MIX efficiently Is a challenging research issue. To the best of the authors' knowledge, most of the state-of-art work primarily …

Marching Schemes For Inverse Scattering Problems In Waveguides With Curved Boundaries, Peng Li, Keying Liu, Weizhou Zhong Jan 2018

Marching Schemes For Inverse Scattering Problems In Waveguides With Curved Boundaries, Peng Li, Keying Liu, Weizhou Zhong

Faculty of Engineering and Information Sciences - Papers: Part B

A marching scheme is developed for inverse scattering problems of the Helmholtz equation in waveguides with curved boundaries. We implement a local orthogonal transform to transform the irregular waveguide in physical plane into a regular rectangle in computing plane. Then the modified Helmholtz system in computational domain is piecewise solved through a second order numerical marching scheme, and we propose a spectral projector based on the truncated local propagating eigenfunction expansion to regularize the marching scheme. In the end, the marching scheme is verified by extensive numerical experiments, and it is shown that the scheme is efficient, stable and accurate …

Friction And Wear Characteristics Of Tio2 Nano-Additive Water-Based Lubricant On Ferritic Stainless Steel, Hui Wu, Jingwei Zhao, Xiawei Cheng, Wenzhen Xia, Anshun He, Jung-Ho Yun, Shuiquan Huang, Lianzhou Wang, Han Huang, Sihai Jiao, Zhengyi Jiang

Faculty of Engineering and Information Sciences - Papers: Part B

The tribological behaviour of innovative TiO2 nano-additive water-based lubricant on ferritic stainless steel (FSS) 445 was characterised on a ball-on-disk tribometer. Non-oxidised (clean) and pre-oxidised FSS 445 disks with original rough surfaces were both applied in the tribological tests at room temperature. The results show that the water-based nanolubricants with concentrations of 0.4–8.0 wt% TiO2 can significantly reduce the coefficient of friction (COF) on the two types of disks. The 4.0 wt% TiO2 lubricant exhibits optimal tribological properties, including the lowest COF and the strongest anti-wear ability on the applied balls under all lubrication conditions. The lubrication …

Biocatalytic Degradation Of Pharmaceuticals, Personal Care Products, Industrial Chemicals, Steroid Hormones And Pesticides In A Membrane Distillation-Enzymatic Bioreactor, Muhammad Bilal Asif, Faisal I. Hai, Jinguo Kang, Jason P. Van De Merwe, Frederic Leusch, William E. Price, Long D. Nghiem

Faculty of Engineering and Information Sciences - Papers: Part B

Laccase-catalyzed degradation of a broad spectrum of trace organic contaminants (TrOCs) by a membrane distillation (MD)-enzymatic membrane bioreactor (EMBR) was investigated. The MD component effectively retained TrOCs (94-99%) in the EMBR, facilitating their continuous biocatalytic degradation. Notably, the extent of TrOC degradation was strongly influenced by their molecular properties. A significant degradation (above 90%) of TrOCs containing strong electron donating functional groups (e.g., hydroxyl and amine groups) was achieved, while a moderate removal was observed for TrOCs containing electron withdrawing functional groups (e.g., amide and halogen groups). Separate addition of two redox-mediators, namely syringaldehyde and violuric acid, further improved TrOC …

A Cost-Effective Software Testing Strategy Employing Online Feedback Information, Zhiquan Zhou, Arnaldo Sinaga, Willy Susilo, Lei Zhao, Kai-Yuan Cai Jan 2018

A Cost-Effective Software Testing Strategy Employing Online Feedback Information, Zhiquan Zhou, Arnaldo Sinaga, Willy Susilo, Lei Zhao, Kai-Yuan Cai

Faculty of Engineering and Information Sciences - Papers: Part B

An online partitioning strategy is presented, in which test cases are selected based on feedback information collected during the testing process. The strategy differs from con- ventional approaches because the partitioning is performed online rather than off-line and because the partitioning is not based on program code or specifications. It can, therefore, be implemented in the absence of the source code or specification of the program under test. The cost-effectiveness of the proposed strategy has been empirically investigated with a set of subject programs, namely, SPACE, SED, GREP, and the Siemens Suite of Programs. The results demonstrate that the proposed …

Residual Stress Effects On Fatigue Crack Growth From A T-Butt Weld Toe, Alan K. Hellier, H. Li, B. G. Prusty, G. M. Pearce, M. Reid, A. M. Paradowska

Faculty of Engineering and Information Sciences - Papers: Part A

A350 grade black mild steel is one of the most widely used structural materials in the world, being commonly found in buildings, bridges and offshore structures.Welding is commonly used to join two plates of structural steel and this often takes the form of a T-butt.In addition, other more complex geometrical joints are often simplified for stress analysis purposes by approximating them as 2-D T-butt plate models (e.g. skewed T-joints, cruciform welded joints, tubular welded joints, pipe–plate joints, etc.).However, all such welds are potentially susceptible to fatigue crack initiation and slow but accelerating growth arising as a result of fluctuating service …

Children's Self-Regulation Of Eating Provides No Defense Against Television And Online Food Marketing, Jennifer A. Norman, Bridget Kelly, Anne T. Mcmahon, Emma J. Boyland, Louise A. Baur, Kathy Chapman, Lesley King, Clare Hughes, Adrian E. Bauman

Faculty of Social Sciences - Papers (Archive)

Exposure to unhealthy food marketing stimulates children's food consumption. A child's responsiveness is influenced by individual factors, resulting in an increased vulnerability to advertising effects among some children. Whether these differential responses may be altered by different parental feeding behaviours is unclear. The purpose of this study was to determine the relationship between parental feeding practices and children's food intake responses to food advertising exposure. A randomised, crossover, counterbalanced, within subject trial was conducted across four, six-day holiday camps in New South Wales, Australia between April 2016 and January 2017 with 160 children (7-12 years, n = 40/camp). Children were …

Faculty of Social Sciences - Papers (Archive)

Background Policies restricting children's exposure to unhealthy food marketing have been impeded by the lack of evidence showing a direct link between food advertising exposure and children's energy intake and body weight. Food advertising exposure increases children's immediate food consumption, but whether this increased intake is compensated for at later eating occasions is not known; consequently the sustained effect on diets remains unclear. Methods We conducted a within-subject, randomised, crossover, counterbalanced study across four, six-day holiday camps in New South Wales, Australia between April 2016 and January 2017. Children (7-12 years, n = 160) were recruited via local schools, email …

Prestimulus Delta And Theta Contributions To Equiprobable Go/Nogo Processing In Healthy Ageing, Frances M. De Blasio, Robert J. Barry

Faculty of Social Sciences - Papers (Archive)

2018 Elsevier B.V. Ongoing EEG activity contributes to ERP outcomes of stimulus processing, and each of these measures is known to undergo (sometimes significant) age-related change. Variation in their relationship across the life-span may thus elucidate mechanisms of normal and pathological ageing. This study assessed the relationships between low-frequency EEG prestimulus brain states, the ERP, and behavioural outcomes in a simple equiprobable auditory Go/NoGo paradigm, comparing these for 20 young (Mage= 20.4 years) and 20 healthy older (Mage= 68.2 years) adults. Prestimulus delta and theta amplitudes were separately assessed; these were each dominant across the midline region, and reduced in …
