A Lightweight Privacy-Preserving Fair Meeting Location Determination Scheme, Hua Shen, Mingwu Zhang, Hao Wang, Fuchun Guo, Willy Susilo

Faculty of Engineering and Information Sciences - Papers: Part B

Equipped with mobile devices, people relied on location-based services can expediently and reasonably organize their activities. But location information may disclose people's sensitive information, such as interests, health status. Besides, the limited resources of mobile devices restrict the further development of location-based services. In this paper, aiming at the fair meeting position determination service, we design a lightweight privacy-preserving solution. In our scheme, mobile users only need to submit service requests. A cloud server and a location services provider are responsible for service response, where the cloud server achieves most of the calculation, and the location services provider determines the …

A Novel Empirical Heat Transfer Model For A Solar Thermal Storage Process Using Phase Change Materials, Yu Bie, Ming Li, Fei Chen, Grzegorz Krolczyk, Lin Yang, Zhixiong Li, Weihua Li

Faculty of Engineering and Information Sciences - Papers: Part B

Numerical and experimental analyses are often used to evaluate the solar thermal system with latent heat thermal energy storage (LHTES). However, the relationship between the numerical simulation and actual heat transfer process is still unclear. This work compares the simulated average temperature of two different phase change materials (PCMs) with experimental result at different operation conditions for the purpose of developing a temperature correction model. A novel empirical heat transfer model is then established to improve the simulation accuracy of PCM-based solar thermal systems. The contributions of this work include that (1) the system performance could be evaluated by the …

Microstructure And Properties Of Spot Welded Joints Of Hot-Stamped Ultra-High Strength Steel Used For Automotive Body Structures, Zhixia Qiao, Hui Jun Li, Lianjin Li, Xiaoyu Ran, Liwen Feng

Faculty of Engineering and Information Sciences - Papers: Part B

Hot-stamped ultra-high strength steels have been widely used in automobile structural parts. Considering the high splash tendency in resistance spot welding due to their extremely high hardness, in this work, microstructural characteristics and mechanical performance of the resistance spot welded ultra-high strength steels are investigated. The results indicate that the interface between the nugget and heat-affected zone (HAZ) is the weakest zone where fractures initiate. In tensile shearing tests, a qualified spot welding joint failed with a button-shaped fracture. Welding defects would significantly decrease the load-carrying capacity and lead to interfacial fracture, except for a button-shaped fracture. In spot welding, …

The test results also showed that circularisation com-bined with intermittent wrapping significantly improved the strength and ductility of …

Strong Tunable Photomixing In Semi-Dirac Materials In The Terahertz Regime, Sunchao Huang, My Hanh Tran, Jack Zuber, Qian Wang, Yiming Zhu, C Zhang

Faculty of Engineering and Information Sciences - Papers: Part B

We demonstrate a strong and anisotropic photomixing effect in an electronic system whose energy–momentum dispersion is parabolic in the 𝑥 direction and linear in the 𝑦 direction, such as a TiO₂/VO₂ multilayered structure. The third-order photoresponses along the linear and parabolic directions have been analyzed and determined quantitatively. We have found a remarkable tunability of the mixing efficiency along the parabolic direction by a small electric field in the linear direction, up to two orders of magnitude. In the terahertz (THz) regime, the third-order response is comparable to the linear response under an applied field of 10 …

High-Throughput Production Of Uniformly Sized Liquid Metal Microdroplets Using Submerged Electrodispersion, Yuxin Zhang, Shiyang Tang, Qianbin Zhao, Guolin Yun, Dan Yuan, Weihua Li

Faculty of Engineering and Information Sciences - Papers: Part B

Microdroplets of gallium-based liquid metal alloys have enabled various applications in the fields of biomedicine, electronics, and chemistry. However, due to the high surface tension of liquid metal, high-throughput production of uniformly sized liquid metal microdroplets is challenging using conventional acoustic or microfluidic methods. Here, adapting the submerged electrodispersion technique that has conventionally been used for generating water-based microdroplets, we develop a simple and straightforward platform for the high-throughput production of near-monodisperse (coefficient of variation less than 5%) liquid metal microdroplets in oil without using microfluidic devices. We demonstrate the capabilities of this method for producing liquid metal microdroplets (diameters …

Performance Evaluation Of Non-Gps Based Localization Techniques Under Shadowing Effects, Ngoc M. Nguyen, Le Chung Tran, Farzad Safaei, Son Lam Phung, Peter James Vial, Nam N. Huynh, Anne N. Cox, Theresa Harada, Johan Barthelemy

Faculty of Engineering and Information Sciences - Papers: Part B

Non-GPS localization has gained much interest from researchers and industries recently because GPS might fail to meet the accuracy requirements in shadowing environments. The two most common range-based non-GPS localization methods, namely Received Signal Strength Indicator (RSSI) and Angle-of-Arrival (AOA), have been intensively mentioned in the literature over the last decade. However, an in-depth analysis of the weighted combination methods of AOA and RSSI in shadowing environments is still missing in the state-of-the-art. This paper proposes several weighted combinations of the two RSSI and AOA components in the form of pAOA + qRSSI, devises the mathematical model for analyzing shadowing …

Thread Effects On The Stiffness Of Bolted Shear Connections, Aziz Ahmed, Lip H. Teh

Faculty of Engineering and Information Sciences - Papers: Part B

This paper investigates the effects of bolt threads on the initial and final stiffnesses of double-shear bolted connections through laboratory tests and finite element (FE) analyses. Nineteen specimens composed of 4.7 mm and 8.0 mm thick structural steel plates with bolt diameters of 20 mm and 30 mm having varying end distances are studied. The investigation, which involves shank and thread bolted connections, has found that the threads reduce the initial stiffness but increase the final stiffness. The FE analysis shows that the reduction in the initial stiffness is due to the bolt threads cutting into the connected plate, increasing …

Faculty of Engineering and Information Sciences - Papers: Part B

Brachytherapy is a complex treatment procedure where radioactive sources are inserted in or close to the tumours to destroy the cancerous cells. Due to the unique properties of scintillation plastic detectors, this study was aimed to characterise an innovative fibre optic dosimetry system as a quality assurance tool during HDR Brachytherapy. Scintillating plastic fibres with different scintillation lengths were prepared and then optically coupled to non-scintillating fibres for light transmission. A transimpedance photodiode amplifier was used to detect positional sensitivities of different fibre probes placed within a solid-water phantom at varying distances above an 192-Ir brachytherapy source located within the …

Creep In Primary Consolidation With Rate Of Loading Approach, Gang Bi, Shua Ni, Dong Wang, Yeqiang Chen, Jianfei Wei, Wenzong Gong

Faculty of Engineering and Information Sciences - Papers: Part B

The debate on creep in primary consolidation is analysed with a power law model following an approach in which creep is considered as rate of loading. According to this approach, primary consolidation is one type of rate of loading. To verify this approach, two types of tests, standard oedometer test and oedometer test with drainage prevented, are conducted on three types of soils (two from NGES and the other from Port of Guangzhou). The result: creep exponents obtained from two kinds of tests agree well with each other. Moreover, the approach is further validated by tracking, for over 80 years, …

Fire-Resistance Of Eccentrically Loaded Rectangular Concrete-Filled Steel Tubular Slender Columns Incorporating Interaction Of Local And Global Buckling, Ghanim Mohammed Kamil, Qing Quan Liang, Muhammad N. S Hadi

Faculty of Engineering and Information Sciences - Papers: Part B

A mathematical model using the fiber approach is presented in this paper for quantifying the strength and fire-resistance of eccentrically loaded slender concrete-filled steel tubular (CFST) columns with rectangular sections incorporating the interaction of local and global buckling. The model utilizes the thermal simulator to ascertain the temperature distribution in cross-sections, and the nonlinear global buckling analysis to predict the interaction responses of local and global buckling of loaded CFST slender columns to fire effects. The initial geometric imperfection, air gap between the concrete and steel tube, tensile concrete strength, deformations caused by preloads, and temperature-dependent material behavior are included …

Boundaries, Spectral Triples And K-Homology, Iain G. Forsyth, Magnus Goffeng, Bram Mesland, Adam C. Rennie

Faculty of Engineering and Information Sciences - Papers: Part B

This paper extends the notion of a spectral triple to a relative spectral triple, an unbounded analogue of a relative Fredholm module for an ideal J◃A. Examples include manifolds with boundary, manifolds with conical singularities, dimension drop algebras, θ-deformations and Cuntz–Pimsner algebras of vector bundles.

The bounded transform of a relative spectral triple is a relative Fredholm module, making the image of a relative spectral triple under the boundary mapping in K-homology easy to compute. We introduce an additional operator called a Clifford normal with which a relative spectral triple can be doubled into a spectral triple.

The Clifford normal …

Influences Of Load And Microstructure On Tribocorrosion Behaviour Of High Strength Hull Steel In Saline Solution, Hui Wu, Yan Li, Zhou Li, Xiawei Cheng, Mahadi Hasan, Hongmei Zhang, Zhengyi Jiang

Faculty of Engineering and Information Sciences - Papers: Part B

The tribocorrosion behaviour of two diferent hull steels (namely, EH36 and EH47) was investigated using a ball-on-disk tribometer under varying normal loads from 10 to 100 N in a 3.5 wt% NaCl saline solution. Sliding in pure water was also performed for a comparison purpose. The results indicate that the corrosion products mainly consist of lath lepidocrocite (γ-FeOOH) with residual NaCl crystals when sliding against both steels EH36 and EH47 in the saline solution. Tribocorrosion on EH36 (pearlitic steel) shows lower coefcient of friction (COF) values than those obtained in water, while tribocorrosion on EH47 (bainitic steel) leads to higher …

Theoretical Study On Positron Scattering By Benzene Over A Broad Energy Range, Alessandra Souza Barbosa, Francisco Blanco, Gustavo Garcia, Marcio H. F. Bettega

Faculty of Engineering and Information Sciences - Papers: Part B

In this paper two theoretical methodologies, the Schwinger multichannel (SMC) method and the independent atom model with the screening corrected additivity rule (IAM-SCAR), were employed to study positron scattering by benzene over a broad impact energy range. The SMC calculations were carried out in the static plus polarization approximation, accounting for the elastic channel, for impact energies up to 20 eV. The IAM-SCAR method covered energies up to 1000 eV to provide total, elastic, ionization, excitation, and positronium formation cross sections. In the low-energy region we discuss how the description of the polarization effects affects the cross sections. In particular, …

Effects Of Grain Boundary On Wear Of Graphene At The Nanoscale: A Molecular Dynamics Study, Jie Zhang, Xinchun Chen, Qiang Xu, Tianbao Ma, Yuanzhong Hu, Hui Wang, Anh Kiet Tieu, Jianbin Luo

Faculty of Engineering and Information Sciences - Papers: Part B

Graphene has shown excellent tribological behaviors, enabling its potential applications as lubricating and anti-wear coatings, however, the grain boundaries (GBs) formed during the preparation process may deteriorate the performance of graphene. Using large-scale molecular dynamics simulations, we study the wear mechanism of graphene GBs with various misorientation angles between two grains. Compared with pure nanoindentation at the GBs, the critical load of wear failure upon nanoscratching across the GBs is much lower due to the synergetic actions of interlocking and pushing between the tip and graphene atoms. The misorientation angle between the adjacent grains significantly effects the onset and fashion …

Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers

The current article presents a framework for the design and support of UOW Online, an entirely new unified university strategy for fully online learning. To aid teachers in the learning design process, we aim to create more awareness for teachers by determining the underlying learning design of their subject. To ensure the approach can be scaled up to cater for potentially hundreds of subjects, the manual labeling serves as input for an Artificial Intelligence (AI) algorithm that will train a model to label intended learning activities automatically. In addition to student demographics and behavior, the learning design and subject content …

Facilitating Social Learning In Teacher Education: A Case Study, Emmy Vrieling, A Van Den Beemt, Maarten F. De Laat

Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers

It is increasingly recognised that social learning by teachers can stimulate professional development. In this study, we search for the social behaviour patterns which can act as a catalyst for professional development, with an explicit focus on student teachers' learning. Based on the 'Dimensions of Social Learning (DSL) Framework', including 4 dimensions and 11 indicators of social learning, the present study explores the social configuration of one network of primary teachers (n = 12), student teachers (n = 12) and teacher educators (n = 2). Two research questions guide this exploration: (1) What patterns of social behaviour in teacher networks …

Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers

The capability to integrate educational technologies has become increasingly important for higher education institutions to be scalable and competitive. Addressing the barriers and enablers for the adoption of educational technologies can potentially catalyse institutional technology initiatives. To address one university’s technology adoption challenges, an ad hoc group of academic and professional staff, representing information technology, the library, educational design, and faculty units engaged in a collaborative reflection and institutional scan to identify the barriers to adoption and potential solutions.Methods: Beginning in April 2018, the group met fortnightly over three months to map the issues related to supporting technology integration across …

Beyond Time And Space: Using Ai To Solve Client Service Challenges Now And Into The Future, Rory L.L. Sie, Debra Nolan

Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers

One of the biggest challenges for libraries today is fulfilling client service requests 24/7. We have skilled staff in the Library during the day and evening, and LiveChat for those not able to visit in person, but what happens after hours? Who is there to help those who work shifts, have children, live on the other side of the planet or just prefer studying at 2am? Artificial intelligence (AI) promises an affordable solution, but will it provide the quality, flexibility and authenticity needed to ensure client satisfaction? Importantly, can the accuracy and veracity of responses be assured? At the University …

Provocations From The Field - Derangement And Resistance: Reflections From Under The Glare Of An Angry Emu, Pattrice Jones

Animal Studies Journal

The situations of emus may illuminate the maladies of human societies. From the colonialism that led Europeans to tamper with Australian ecosystems through the militarism that mandated the Great Emu War of 1932 to the consumer capitalism that sparked a global market for ‘exotic’ emus and their products, habits of belief and behaviour that hurt humans have wreaked havoc on emus. Literally de-ranged, emus abroad today endure all of the estrangements of émigrés in addition to the frustrations and sorrows of captivity. In Australia, free emus struggle to survive as climate change parches already diminished and polluted habitats. We have …

Kaimangatanga: Maori Perspectives On Veganism And Plant-Based Kai, Kirsty Dunn

Animal Studies Journal

In this paper – drawing from a range of food blogs and social media pages – I consider both the ways in which Māori writers discuss some of the barriers and cultural conflicts experienced within the realm of vegan ethics, as well as their perspectives on various facets of Te Ao Māori (the Māori world) such as kaitiakitanga (guardianship), hauora (holistic health and wellbeing), and rangatiratanga (sovereignty) which have influenced their attitudes and approaches towards veganism and plant-based diets. I argue that these diverse perspectives provide a valuable means of analysing and critiquing both the dominant ethics and attitudes which …

Space On Par: A Short Performance For One Performer, Peta Tait

Animal Studies Journal

Space on Par is a short performance text that uses gentle humour to communicate an alternative perspective on how open space is used by humans and nonhuman animals, in this instance a golf course. If playing golf for enjoyment is puzzling behaviour for a nonhuman observer, it can emphasise human refusal to recognise the physical and spatial rights of other species and their needs for survival. The effort to educate about the treatment of animals can include theatrical characters who blur the species identities to make a point, and Space on Par inverts the invisibility of the gaze of the …

‘Let’S Find Out! What Do I Make?’ [Review] Kathryn Gillespie, The Cow With Ear Tag #1389. University Of Chicago Press, 2018. 272pp, Hayley Singer

Animal Studies Journal

I’m halfway through Kathryn Gillespie’s book when it hits me. This enormous shadow lake of sadness I’ve been walking around with – it’s dairy. It’s the electric prods that move cows through pens. It’s the endless stream of bovine bodies flowing around the world. It’s the ginormous global wet market of milk and semen. It’s the aftermath of shotgun blasts delivered to immobile cows, to fugitive cows, still ringing in my ears. It’s the call of mothers and children separated at auction yards. It’s that we’re living in a context of (almost) compulsory dairy consumption. It’s that writing about the …

[Review] Jacob Bull, Tora Holmberg And Cecilia Åsberg, Editors, Animal Places: Lively Cartographies Of Human-Animal Relations. Routledge, 2018. 276pp, Zoei Sutton

Animal Studies Journal

It’s 2016 and rats are ‘taking over’ in Malmö, Sweden. Forced out of the sewers by flooding, the sight of usually-hidden rats now visible on streets and playgrounds (not to mention their dead bodies in the river) has humans calling for sanitation through eradication to ‘restore’ social order. In daring to exist ‘out of place’ in their search for food the rats ‘turn from tolerated, illegitimate, but invisible waste-workers, to ‘trash animals’ (1). This dramatic scene which opens Animal Places ‘shows how space, place and human-animal relations intersect, thereby producing diversity of effect, boundary work and political action’ (1). Building …
