Another Atlas, Etienne Turpin
Faculty of Engineering and Information Sciences - Papers: Part A
Another Atlas builds on the work of Lize Mogel and Alexis Bhagat's 2007 compendium of cartographic investigations into power, networks and social justice. The book and subsequent touring exhibition brought together work from artists, designers, geographers and activists all focusing on the role mapping has in our shared social structures. The different works lead to questions of; Who has the right to map? What do they have the right to map? How mapping changes our world. Each of the artists selected represent ways information can be gathered and how forms of mapping can be challenged.

Setting a holistic scope for the implementation beyond technical concerns to include educational outcomes was critical to the success achieved and has laid the foundation for further …
Non-Collapsing In Fully Nonlinear Curvature Flows, Ben H. Andrews, Mat Langford, James A. Mccoy
Non-Collapsing In Fully Nonlinear Curvature Flows, Ben H. Andrews, Mat Langford, James A. Mccoy
Faculty of Engineering and Information Sciences - Papers: Part A
We consider embedded hypersurfaces evolving by fully nonlinear flows in which the normal speed of motion is a homogeneous degree one, concave or convex function of the principal curvatures, and prove a non-collapsing estimate: Precisely, the function which gives the curvature of the largest interior sphere touching the hy- persurface at each point is a subsolution of the linearized flow equation if the speed is concave. If the speed is convex then there is an analogous statement for exterior spheres. In particular, if the hypersurface moves with positive speed and the speed is concave in the principal curvatures, then the …

Influence Of Formulated Chemical Cleaning Reagents On The Surface Properties And Separation Efficiency Of Nanofiltration Membranes, Alexander Simon, William E. Price, Long D. Nghiem
Influence Of Formulated Chemical Cleaning Reagents On The Surface Properties And Separation Efficiency Of Nanofiltration Membranes, Alexander Simon, William E. Price, Long D. Nghiem
Faculty of Engineering and Information Sciences - Papers: Part A
This study investigated the impact of two caustic and one acidic cleaning formulations (namely MC11, PC98, and MC3, respectively) on the properties and separation efficiency of three different nanofiltration (NF) membranes (namely NF270, NF90 and TFC-SR100). Overall, the impact of chemical cleaning on surface properties and rejection was membrane and cleaning reagent specific. It was driven mostly by conformational changes of the membrane polymeric active skin layer in response to an extreme caustic or acidic environment and to a certain extent by the adsorption of cleaning additives (e.g., surfactants and chelating reagents). The influence of chemical cleaning on the membrane …
Neutron Generator Burst Timing Measured Using A Pulse Shape Discrimination Plastic Scintillator With Silicon Photomultiplier Readout, R M. Preston, J Eberhardt, J R. Tickner
Neutron Generator Burst Timing Measured Using A Pulse Shape Discrimination Plastic Scintillator With Silicon Photomultiplier Readout, R M. Preston, J Eberhardt, J R. Tickner
Faculty of Engineering and Information Sciences - Papers: Part A
An EJ-299-34 plastic scintillator with silicon photomultiplier (SiPM) readout was used to measure the fast neutron output of a pulsed Thermo-Fisher A-325 Deuterium-Tritium sealed tube neutron generator (STNG). The SiPM signals were handled by a prototype digital pulse processing system, based on a free-running analogue to digital converter feeding a digital signal processor (DSP). Pulse shape discrimination was used to distinguish between detected fast-neutrons and gammas. Pulse detection, timing, energy and shape were all processed by the DSP in real-time.

Capacity Deferral Credit Evaluation Of Renewable Distributed Generation, M A. Abdullah, K M. Muttaqi, A P. Agalgaonkar, D Sutanto
Faculty of Engineering and Information Sciences - Papers: Part A
Renewable distributed generation (DG) units can aid in distribution network planning and can be utilized in distribution expansion planning. In order to support the development of distributed renewable resources in the distribution network and to make these resources competitive in the energy market, a well justified credit scheme needs to be devised. In this paper, an analytical method has been developed to estimate the capacity deferral credit of renewable DGs that can be claimed from distribution system operators (DSOs) due to the deferral of conventional distribution network expansion options. The distribution network adequacy has been assessed using the combined multistate …

Power Quality Emission Assessment Of Photovoltaic Inverters Based On Iec Technical Report 61000-3-15:2011, Devinda Perera, Philip Ciufo, Lasantha G. Meegahapola, Sarath Perera
Faculty of Engineering and Information Sciences - Papers: Part A
The International Electrotechnical Committee Technical Report IEC 61000-3-15:2011 provides electromagnetic compatibility requirements and test conditions for distributed generators up to 75 A per phase. In the current research, two commercially available photovoltaic (PV) inverters up to the capacity of 3600 W were tested following the guidelines proposed in IEC 61000-3-15 in relation to low order harmonic emission and flicker emission. In addition, the harmonic and flicker emission behaviour of the PV inverters were investigated under varying irradiation conditions. Both PV inverters were observed to comply with the emission requirements prescribed by the technical report under most conditions except for even …
Effect Of Confining Pressure And Frequency On The Deformation Of Ballast, Pramod Kumar Thakur, Jayan Sylaja Vinod, Buddhima Indraratna
Effect Of Confining Pressure And Frequency On The Deformation Of Ballast, Pramod Kumar Thakur, Jayan Sylaja Vinod, Buddhima Indraratna
Faculty of Engineering and Information Sciences - Papers: Part A
Increasing the speed and frequency of trains with the same static axle weight imparts higher dynamic axle loads more frequently. When this occurs on existing track which has not been designed for such loading there can be increased rates of ballast degradation, characterised by unacceptable deformation and lateral spread, leading to more frequent requirements for track maintenance. Recent studies carried out at the University of Wollongong highlighted that confining pressure and frequency have a significant influence on the permanent deformation and degradation of ballast. However, confinement required to keep the deformation and degradation of the ballasted track to an acceptable …

Inclusion Reactivity: Morphology And Composition Changes Of Spinel (Mgal2o4) In Steel, Neslihan Dogan, Raymond Longbottom, Mark Henry Reid, Michael W. Chapman, Paton Wilson, Les Moore, Brian Monaghan
Faculty of Engineering and Information Sciences - Papers: Part A
Due to an ever increasing demand for cleaner, high quality steels, there is an increasing push for steelmakers to lower the non-metallic inclusion contents of the steel they produce. Understanding inclusion reactivity in steel is key in producing high quality steels at high production rates. Our current knowledge in controlling and predicting inclusion development during liquid steel processing is limited. In this study, spinel (MgAI204) inclusions of close to stoichiometric MgO.AI2O3 and known size distribution where added to the liquid steel bath prior to assessing their reactivity. The pO2 of the gas phase was controlled to 10-13 atm throughout the …

Amenability For Fell Bundles Over Groupoids, Aidan Sims, Dana Williams
Faculty of Engineering and Information Sciences - Papers: Part A
We establish conditions under which the universal and reduced norms coincide for a Fell bundle over a groupoid. Specifically, we prove that the full and reduced C-algebras of any Fell bundle over a measurewise amenable groupoid coincide, and also that for a groupoid G whose orbit space is T0, the full and reduced algebras of a Fell bundle over G coincide if the full and reduced algebras of the restriction of the bundle to each isotropy group coincide.

Analysis Of Axisymmetric Cup Forming Of Metal Foil And Micro Hydroforming Process, Hideki Sato, Kenichi Manabe, Dongbin Wei, Zhengyi Jiang
Faculty of Engineering and Information Sciences - Papers: Part A
A novel forming method "micro hydromechanical deep drawing (MHDD)" is focused to improve the tribological property and forming limit. In this study, a theoretical model for MHDD is developed to investigate the size effect on deformation behavior in micro hydromechanical deep drawing. The effects of fluid pressure, the difference of friction coefficients at inner pockets and outer pockets are considered in the investigation on the size effect of tribological property. The friction force decreases as the scale factor decreases in MHDD process. It is also found that the tribological property in micro scale can be improved by applying the fluid …
Inertial Focusing In A Straight Channel With Asymmetrical Expansion-Contraction Cavity Arrays Using Two Secondary Flows, Jun Zhang, M Li, Weihua Li, Gursel Alici
Inertial Focusing In A Straight Channel With Asymmetrical Expansion-Contraction Cavity Arrays Using Two Secondary Flows, Jun Zhang, M Li, Weihua Li, Gursel Alici
Faculty of Engineering and Information Sciences - Papers: Part A
The focusing of particles has a variety of applications in industry and biomedicine, including wastewater purification, fermentation filtration, and pathogen detection in flow cytometry, etc. In this paper a novel inertial microfluidic device using two secondary flows to focus particles is presented. The geometry of the proposed microfluidic channel is a simple straight channel with asymmetrically patterned triangular expansion–contraction cavity arrays. Three different focusing patterns were observed under different flow conditions: (1) a single focusing streak on the cavity side; (2) double focusing streaks on both sides; (3) half of the particles were focused on the opposite side of the …

A Classification Theorem For Helfrich Surfaces, James Mccoy, Glen Wheeler
A Classification Theorem For Helfrich Surfaces, James Mccoy, Glen Wheeler
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper we study the functional W , which is the the sum of the Willmore energy, weighted surface area, and weighted volume, for surfaces immersed in R^3. This coincides with the Helfrich functional with zero `spontaneous curvature'. Our main result is a complete classification of all smooth immersed critical points of the functional with nonnegative surface area weight and small L^2 norm of tracefree curvature. In particular we prove the non-existence of critical points of the functional for which the surface area and enclosed volume are positively weighted.
Strong Amicable Orthogonal Designs And Amicable Hadamard Matrices, Jennifer Seberry
Strong Amicable Orthogonal Designs And Amicable Hadamard Matrices, Jennifer Seberry
Faculty of Engineering and Information Sciences - Papers: Part A
Amicable orthogonal designs have renewed interest because of their use in mobile communications. We show the existence of strong amicable orthogonal designs, AOD(n: 1, n - 1; 1, n - 1), for n = pr + 1, p ≡ 3 (mod 4) a prime and for n = 2r, n a non-negative integer in a form more suitable for communications. Unfortunately the existence of amicable Hadamard matrices is not enough to demonstrate the existence of strong amicable orthogonal designs.
Inter-Occlusion Reasoning For Human Detection Based On Variational Mean Field, Duc Thanh Nguyen, Wanqing Li, Philip O. Ogunbona
Inter-Occlusion Reasoning For Human Detection Based On Variational Mean Field, Duc Thanh Nguyen, Wanqing Li, Philip O. Ogunbona
Faculty of Engineering and Information Sciences - Papers: Part A
Detecting multiple humans in crowded scenes is challenging because the humans are often partially or even totally occluded by each other. In this paper, we propose a novel algorithm for partial inter-occlusion reasoning in human detection based on variational mean field theory. The proposed algorithm can be integrated with various part-based human detectors using different types of features, object representations, and classifiers. The algorithm takes as the input an initial set of possible human objects (hypotheses) detected using a part-based human detector. Each hypothesis is decomposed into a number of parts and the occlusion status of each part is inferred …

Simulation Of Defects In Micro-Deep Drawing Of An Aluminium Alloy Foil, Syamsul Hadi, Hai-Liang Yu, Kiet Tieu, Cheng Lu
Faculty of Engineering and Information Sciences - Papers: Part A
Micro-forming refers to the application of conventional forming processes to manufacture products from ultra-thin sheet materials. While attempting to meet the increasing demand for cost-effective manufacturing of micro-formed components, it is very important to reduce the defects in the products. In this paper, we report a number of Finite Element (FE) simulations of the micro-deep drawing process with various sample thicknesses and eccentric distances. The simulations indicated that when the sample thickness is nearly equal to the gap between the plunger and the die, the sample is likely to develop fractures at the bottom corner. When the sample thickness is …

Study On The Influence Of Temperature On The Surface Asperity In Micro Cross Wedge Rolling, H N. Lu, D B. Wei, Z Y. Jiang, D Wu, X M. Zhao
Faculty of Engineering and Information Sciences - Papers: Part A
When the common deformation processes are scaled down to micro/meso dimensions, size effect is the particular phenomena in microforming, which is related to the dominant influence of single grains inside the micropart. The conventional cross wedge rolling (CWR) is introduced into the micro scale in order to take the advantages of CWR. The micro cross wedge rolling (MCWR) has to confront with the phenomena of size effect that occurs in the common microforming processes inevitably. One of the approaches to compensate size effect is to increase the deforming temperature. An increased formability is achieved because more slip systems of polycrystal …

Optical Image Encryption Based On Chaotic Baker Map And Double Random Phase Encoding, Ahmed M. Elshamy, Ahmed N. Z Rashed, Abd El-Naser A. Mohamed, Osama S. Faragalla, Yi Mu, Saleh A. Alshebeili, F E Abd El-Samie
Optical Image Encryption Based On Chaotic Baker Map And Double Random Phase Encoding, Ahmed M. Elshamy, Ahmed N. Z Rashed, Abd El-Naser A. Mohamed, Osama S. Faragalla, Yi Mu, Saleh A. Alshebeili, F E Abd El-Samie
Faculty of Engineering and Information Sciences - Papers: Part A
This paper presents a new technique for optical image encryption based on chaotic Baker map and Double Random Phase Encoding (DRPE). This technique is implemented in two layers to enhance the security level of the classical DRPE. The first layer is a pre-processing layer, which is performed with the chaotic Baker map on the original image. In the second layer, the classical DRPE is utilized. Matlab simulation experiments show that the proposed technique enhances the security level of the DRPE, and at the same time has a better immunity to noise.

Performance Evaluation Of Cooperative Communications For Stfc Mb-Ofdm Uwb, Zixuan Lin, Le Chung Tran, Farzad Safaei
Faculty of Engineering and Information Sciences - Papers: Part A
Recently, the combination of cooperative communication, Space-Time-Frequency Codes (STFCs) and Multiband OFDM Ultra-Wideband (MB-OFDM UWB) has been proposed to improve the data rate, system capacity and reliability. This paper provides insightful performance evaluation for our previous proposed cooperative communication schemes for MBOFDM UWB systems. In particular, this paper shows that the usefulness of cooperative communication schemes is decided by the mutual relation between the signal-to-noise ratio (SNR) of the inter-node links, referred to as inter-node SNR, and that of the uplinks, which is referred to as uplink SNR. For a certain uplink SNR value, cooperative communication becomes useful when the …
An Image-Based Approach For Classification Of Human Micro-Doppler Radar Signatures, Fok Hing Chi Tivive, Son Lam Phung, Abdesselam Bouzerdoum
An Image-Based Approach For Classification Of Human Micro-Doppler Radar Signatures, Fok Hing Chi Tivive, Son Lam Phung, Abdesselam Bouzerdoum
Faculty of Engineering and Information Sciences - Papers: Part A
With the advances in radar technology, there is an increasing interest in automatic radar-based human gait identification. This is because radar signals can penetrate through most dielectric materials. In this paper, an image-based approach is proposed for classifying human micro-Doppler radar signatures. The time-varying radar signal is first converted into a time-frequency representation, which is then cast as a two-dimensional image. A descriptor is developed to extract micro-Doppler features from local time-frequency patches centered along the torso Doppler frequency. Experimental results based on real data collected from a 24-GHz Doppler radar showed that the proposed approach achieves promising classification performance.

Realizing Fully Secure Unrestricted Id-Based Ring Signature In The Standard Model Based On Hibe, Man Ho Au, Joseph K. Liu, Willy Susilo, Jianying Zhou
Faculty of Engineering and Information Sciences - Papers: Part A
We describe a secure and unrestricted identity-based ring signature scheme in the standard model. Our construction is provably fully secure in the standard model under static assumptions and is motivated by an existing HIBE scheme. Our observation on the relationship between ID-based ring signatures and HIBE is of interest to researchers in other fields as well. Following the strongest anonymity definition in ring signatures, we define a new level of anonymity for ID-based ring signatures in which the attacker can specify the randomness used in the creation of the user secret key, in addition to the private key generators master …

Secure Rfid Ownership Transfer Protocols, Nan Li, Yi Mu, Willy Susilo, Vijay Varadharajan
Faculty of Engineering and Information Sciences - Papers: Part A
An RFID tag could change hands many times during its lifetime. In a retail chain, the ownership of the tag is instituted by the supplier who initially owns the tag. In the view of a buyer, the validity of the current tag ownership and the originality of supplier are most important. In typical RFID ownership transfer protocols, the knowledge of the tag's authentication key proves the ownership. However, it is insufficient against an active attacker, since tags are usually lack of tamper-proof protections. Ownership transfer relies on a successful verification of tag's supplier and current ownership. In this paper, we …

Systematic Network Design For Liner Shipping Services, Shuaian Wang, Zhiyuan Liu, Qiang Meng
Faculty of Engineering and Information Sciences - Papers: Part A
A systematic design for a liner shipping network was addressed. Many practical features in real-world operations, including multiple types of containers, container transshipment operations, empty container repositioning, origin-to-destination transit time constraints, consistent services with the current network, and joint services with other liner shipping companies, were considered. Given a set of candidate ship routes, some of these routes had to be used, and the use of others was optional. A mixed-integer linear programming model was proposed for the selection of optional ship routes. The solution of this model provided the laden and empty container flow on the selected ship routes. …
Simplified Boundary Element Method For Kinematic Response Of Single Piles In Two-Layer Soil, Fayun Liang, Haibing Chen, Wei Dong Guo
Simplified Boundary Element Method For Kinematic Response Of Single Piles In Two-Layer Soil, Fayun Liang, Haibing Chen, Wei Dong Guo
Faculty of Engineering and Information Sciences - Papers: Part A
A simple approach is formulated to predict the elastic, kinematic pile bending during harmonic or transient excitation for a circular pile (rather than a simplified thin strip). The kinematic response of a pile embedded in two-layer soil is resolved in the frequency domain caused by the upward propagation of shear waves from the underlying bedrock. The simplified approach is generally valid to nonhomogeneous soil profiles, in light of the good comparison with the dynamic FE method and BDWF solution. It employs the soil-displacement-influence coefficients Is to consider the pile-soil interaction (resembling the spring constant kx in the BDWF) and provides …

Faculty of Engineering and Information Sciences - Papers: Part A
Base isolation is the most popular seismic protection technique for civil engineering structures. However, research has revealed that the traditional base isolation system due to its passive nature is vulnerable to two kinds of earthquakes, i.e. the near-fault and far-fault earthquakes. A great deal of effort has been dedicated to improve the performance of the traditional base isolation system for these two types of earthquakes. This paper presents a recent research breakthrough on the development of a novel adaptive seismic isolation system as the quest for ultimate protection for civil structures, utilizing the field-dependent property of the magnetorheological elastomer (MRE). …
Electromagnetically Induced Transparency Of Charge Pumping In A Triple-Quantum-Dots With Λ-Type Level Structure, Chun Guan, Yunhui Xing, Chao Zhang, Zhongshui Ma
Electromagnetically Induced Transparency Of Charge Pumping In A Triple-Quantum-Dots With Λ-Type Level Structure, Chun Guan, Yunhui Xing, Chao Zhang, Zhongshui Ma
Faculty of Engineering and Information Sciences - Papers: Part A
We demonstrate an electromagnetically induced electron transparency (EIET) in electron transport through a coupled triple-quantum-dots system under two radiation fields. The direct evidence of EIET is that an electron can travel from the left dot to the right dot without any effect from the center dot. The EIET (position, height, and symmetry) can be tuned by several controllable parameters of the radiation fields, such as the Rabi frequencies and detuning frequencies. The result offers a resonant transport tuning technique using radiation fields.

Dynamic Testing Of Tekseal High Yield Grout To Provide An Orepass Plug Designed For Impact, I V. S Mutton, Alexander Remennikov, D Pateman
Faculty of Engineering and Information Sciences - Papers: Part A
Significant wear in orepasses particularly in the brow and chute areas is proportional to the tonnage throughput with increased wear associated with running orepasses empty. During planned shutdowns it may be necessary to isolate maintenance crews from objects falling from orepasses. In the last 15 years grout orepass plugs that can later be easily removed have been poured above chute maintenance areas. These provide protection from high energy impact and isolating workers from the hazard. Construction and removal methods will be briefly explained. Since it is not feasible to investigate the problem of orepass plug impact response using full-scale experimental …
