A Reflective Closed Loop Approach For Implementing A New Authentic Assessment-Based Teaching Facility For Electric Motor And Drive Systems, Craig Mclauchlan, Philip Ciufo, Sarath Perera
Faculty of Engineering and Information Sciences - Papers: Part A
BACKGROUND A new teaching facility with a focus on electric motor and drive systems has been implemented at the University of Wollongong. This facility aspires to use authentic assessment principles to assist in preparing students to properly utilise electric motor and drive systems in professional practice. In an attempt to realise this aim, the implementation of this facility was undertaken using a reflective closedloop approach, addressing the educational outcomes achieved by the students. 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 …

Enhancement Of The Refrigerant Capacity In Low Level Boron Doped La0.8gd0.2fe11.4si1.6, P Shamba, R Zeng, Jianli Wang, S J. Campbell, S X. Dou
Faculty of Engineering and Information Sciences - Papers: Part A
The effects of boron doping on the itinerant-electron metamagnetic (IEM) transition and the magnetocaloric effects (MCEs) in the cubic NaZn13-type La0.8Gd0.2Fe11.4Si1.6 compound have been investigated. The Curie temperature, TC, of La0.8Gd0.2Fe11.4Si1.6Bx compounds with x=0, 0.03, 0.06, 0.2 and 0.3 was found to increase from 200 K to 222 K with increase in boron doping, x. The maximum values of the isothermal magnetic entropy change, ΔSM, (derived using the Maxwell relation for a field change ΔB=0-5 T) in La0.8Gd0.2Fe11.4Si1.6Bx with x=0, 0.03, 0.06, 0.2 and 0.3 are 14.8, 16, 15, 7.5 and 6.6 J kg−1 K−1 respectively, with corresponding values of …
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 …
Metacapitalism Vs Healthcare, Sanja Pupovac, George M. Mickhail
Metacapitalism Vs Healthcare, Sanja Pupovac, George M. Mickhail
Faculty of Commerce - Papers (Archive)
The aim of this paper is to critically examine the effect of the MetaCapitalism strategy changes on Australian healthcare sector companies during the period 1989-2007, and to establish whether there is any relationship between those changes and any adverse corporate consequences, such as: corporate collapses, acquisitions, mergers, delisting from the ASX 200. The main rationale behind the MetaCapitalism strategy, is that by aggressively reducing physical assets, outsourcing production and downsizing of the workforce, then firms will become at the same time efficient and profitable through participating in this highly competitive technological era. However, this uninhibited pursuit of efficiency by corporations …
Validly Measuring Destination Image In Survey Studies, Sara Dolnicar, Bettina Grun
Validly Measuring Destination Image In Survey Studies, Sara Dolnicar, Bettina Grun
Faculty of Commerce - Papers (Archive)
Destination image is among the most frequently measured constructs in empirical survey research. Academic tourism researchers tend to use multi-category scales, often referring to them as "Likert scales," while industry typically uses "pickany" measures. But which leads to results that are more valid? Findings from a large-scale experimental study show that a "forced-choice full binary" format (where respondents have to tick "yes" and "no" for each destination-attribute combination) performs better than both current preferred formats in academic and applied studies.

Realising The Potential Of Peer-To-Peer Learning: Taming A Mooc With Social Media, Emily Rose Purser, Angela Towndrow, Ary Aranguiz
Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers
ELearning and Digital Cultures, from the University of Edinburgh, was offered on the Coursera platform in January 2013. Over 40,000 enrolled, from every continent. The course was aimed mainly at educators wanting to “deepen their understanding of what it means to teach and learn in the digital age”. As participants, we experienced deep and significant learning, very much through social media. The peer-to-peer learning we engaged in and benefitted from was not traditionally organised ‘group work’ or micro-managed interaction, but something more fluid, open, student-initiated and led, that seems to have gone to the very core of what online learner …

Tolkien’S Japonisme: Prints, Dragons, And A Great Wave, Michael Organ
Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers
The original September 1937 George Allen & Unwin edition of The Hobbit features artwork by J.R.R. Tolkien along with an accompanying dust jacket. This latter work is a modern, stylized graphic design composed of a not entirely symmetrical view of a Middle-earth landscape (night to the left, day to the right), with the Lonely Mountain rising in the distant center, flanked by steeply sloped, snow-covered Misty Mountains and in the foreground Mirkwood’s dense, impenetrable forests. Additional features include a crescent moon, the sun, a dragon, eagles, a lake village, and a rapier-like path—a straight road— heading toward a darkened, megalithic …

'Please Mr Frodo, Is This New Zealand? Or Australia?'... 'No Sam, It's Middle-Earth.', Michael K. Organ
Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers
The exploitation of JRR Tolkien's Middle-earth by Tourism New Zealand following the success of Peter Jackson's Lord of the Rings films and the release of the first part of The Hobbit has been met with accusations of cultural racism by Maori, misrepresentation by Pakeha and re-appropriation by independent British filmmakers, writes Michael Organ.
Myriad Mirrors: Doppelgangers And Doubling In The Vampire Diaries, Kimberley Mcmahon-Coleman
Myriad Mirrors: Doppelgangers And Doubling In The Vampire Diaries, Kimberley Mcmahon-Coleman
Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers
As Samantha George notes in Chapter 4 above, mirroring is of fundamental importance in Gothic literature and film. It is also a prevalent trope in the CW network teen drama, The Vampire Diaries. The television series is itself a ‘doubling’ in that it is an adaptation of a series of novels by L. J. Smith, creating a situation wherein the same central characters inhabit the parallel townships of the novels’ Fells Church and television’s Mystic Falls, and consequently have histories which are, at times, contradictory.2 The television version also explicitly explores the concept of the doppelgänger, and thus the idea …

Managing Institutional Change Through Distributive Leadership Approaches: Engaging Academics And Teaching Support Staff In Blended And Flexible Learning, Merilyn Childs, Mark Brown, Mike Keppell, Zeffie Nicholas, Carole Hunter, Natasha Hard
Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers
Higher Education institutions face a challenge: how to transform traditional learning and teaching to create enhanced learning for current digital age students. In some universities this challenge is acute - particularly in those Universities that focus on blended and flexible learning (BFL), and distance education (DE) approaches. Many universities have emphasised the development of leadership capacity. From 2008 to 2011, utlising a partnership research grant funded by DEHub, Charles Sturt University and Massey University studied their approaches to fostering change in blended and flexible learning and DE. The study research question was: What do the strategies and activities designed to …

Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers
How do we measure performance? How do we report it? For universities, performance can be measured in a variety of ways - the number of students enrolled, the number of graduates, theses completions, research grant funding obtained, research outputs in the form of publications, prestige attained by staff and the institution as a whole, and reputation. Some of these performance measures are easily quantifiable, others less so, e.g. prestige and reputation. And of course performance measurement regimes change with time, such that what was considered an appropriate measure at one time may be deemed no longer relevant or even desirable. …

Ndive: The Story Of How Logistics And Supply Chain Management Could Be Taught, Torsten Reiners, Lincoln C. Wood, Sue Gregory, Natasha Petter, Hanna M. Teras, Vanessa Chang, Christian Gutl, Janice A. Herrington
Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers
One major element of supply chain management education is helping learners to grasp the complexity, the challenges, and the efficient management of the multiple dimensions in supply chains. Each decision made can 'ripple' through supply chains and have serious repercussions that may include causing millions of dollars in damage or triggering a chain of events that degrade the quality of life for people, society, or the environment. We can teach relevant theory and train learners for some situations that do not require immediate responses. However, we remain disadvantaged by the constraints of time and space; observation of a real supply …
Synergising Mathematics Support Within A University Setting, Lesley Wilkins
Synergising Mathematics Support Within A University Setting, Lesley Wilkins
Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers
Students enter university with a variety of mathematical backgrounds. Some are not adequately prepared for the mathematics involved in their preferred, non-specialist mathematics courses. Many bring emotional conflicts about mathematics which affect their ability to learn. University of Wollongong recently appointed a Mathematics Support Lecturer to its Learning Development team whose role is to provide assistance to students who find the mathematics involved in their courses "challenging". This paper looks at the development of this role with emphasis on the requirement of mathematics to "synergise" with other courses, contexts and competencies within university studies and examines the broad cultural contexts …
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
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.

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
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 …

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 …

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 …
