A Novel Integrated Model To Measure Supplier Performance Considering Qualitative And Quantitative Criteria Used In The Supplier Selection Process, Alptekin Ulutas, Senevi Kiridena, Peter Gibson, Nagesh Shukla
Faculty of Engineering and Information Sciences - Papers: Part A
Supplier evaluation has become a significant topic over the past few decades, as companies have become more outsourced oriented. However, previous research on this topic has not paid adequate attention to the limitations associated with the availability of accurate and reliable data relating to the performance of potential suppliers. In an attempt to address this issue, this paper proposes a novel supplier evaluation model that can handle imprecise quantitative and qualitative data. Additionally, Decision Maker's judgement regarding both qualitative and quantitative criteria are incorporated into this model so that a more comprehensive and realistic assessment of supplier performance can be …
Bonding Of Mg-Base Metallic Glass Through Rapid Resistive Welding, Karl F. Shamlaye, Kevin J. Laws, Bob De Jong, Michael Ferry
Bonding Of Mg-Base Metallic Glass Through Rapid Resistive Welding, Karl F. Shamlaye, Kevin J. Laws, Bob De Jong, Michael Ferry
Faculty of Engineering and Information Sciences - Papers: Part A
Efficient joining of Magnesium-base bulk metallic glass can be achieved via bonding through resistance welding using rapid heating rates. Bonding of Mg-base metallic glasses (as well as regular magnesium alloys) is a process hindered by the ease of oxide formation in these materials. In this work, resistance welding of Mg65Cu25Y10 metallic glass sheets was investigated up to 627 K , below the liquidus temperature; and also within the supercooled liquid region (443-483 K) of the metallic glass; during processing times of a few seconds, creating strong joins -even when processed in air. It is seen that a fluxing pre-treatment of …

Faculty of Engineering and Information Sciences - Papers: Part A
The goal of this work was to investigate the agreement of physical parameters related to the particle track structure on the nanometer scale, obtained by means of a detailed track structure simulation (PTra) as well as by a rapid analytical approach. Parameters describing the tracks of secondary electrons produced by 0.3 MeV/u C6+-ions were of particular interest as those particles are densely ionizing. For this purpose, the target volume in form of a nanometric water cylinder was positioned at different radial distances from the ion trajectory and track structure parameters were determined as function of the radial distance. While the …

On Combining Chase-2 And Sum-Product Algorithms For Ldpc Codes, Sheng Tong, Huijuan Zheng
On Combining Chase-2 And Sum-Product Algorithms For Ldpc Codes, Sheng Tong, Huijuan Zheng
Faculty of Engineering and Information Sciences - Papers: Part A
This letter investigates the combination of the Chase-2 and sum-product (SP) algorithms for low-density parity-check (LDPC) codes. A simple modification of the tanh rule for check node update is given, which incorporates test error patterns (TEPs) used in the Chase algorithm into SP decoding of LDPC codes. Moreover, a simple yet effective approach is proposed to construct TEPs for dealing with decoding failures with low-weight syndromes. Simulation results show that the proposed algorithm is effective in improving both the waterfall and error floor performance of LDPC codes.

Secure And Practical Key Distribution For Rfid-Enabled Supply Chains, Tieyan Li, Yingjiu Li, Guilin Wang
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper, we present a fine-grained view of an RFID-enabled supply chain and tackle the secure key distribution problem on a peer-to-peer base. In our model, we focus on any pair of consecutive parties along a supply chain, who agreed on a transaction and based on which, certain RFID-tagged goods are to be transferred by a third party from one party to the other as in common supply chain practice. Under a strong adversary model, we identify and define the security requirements with those parties during the delivery process. To meet the security goal, we first propose a resilient …

Transactive Memory Systems: Exploring Task, Expertise And People (Tep) Unit Formation In Virtual Teams: Conceptualization And Scale Measurement Development, Mohamed Imran Mohamed Ariff, Simon K. Milton, R Bosua, Rajeev Sharma
Faculty of Engineering and Information Sciences - Papers: Part A
Transactive Memory Systems (TMS) are important cognitive constructs to share knowledge and control and coordinate interdependent tasks in teams. The construction of Transactive Memory Systems involves a number of key phases that lead up to the actual formation of a team’s TMS. In particular, the development of Task-Expertise-People (TEP) units, form an essential part of the development of a team’s Transactive Memory System. At this stage very little is known of how Task- Expertise-People units are formed in virtual teams. This paper addresses this problem by following an inductive, quantitative method to develop a measurement scale for TEP formation in …
The Effect Of Chromium Addition On The Strain Ageing And Recrystallisation Behaviour Of Low Carbon Steel, Elena Pereloma, V Bata, Azdiar A. Gazder
The Effect Of Chromium Addition On The Strain Ageing And Recrystallisation Behaviour Of Low Carbon Steel, Elena Pereloma, V Bata, Azdiar A. Gazder
Faculty of Engineering and Information Sciences - Papers: Part A
The strain ageing and recrystallisation behaviour of conventional low carbon A06 steel was compared with those containing varying amounts of chromium (0.26, 0.52 and 0.74 wt.%). The results show that the A06 steel undergoes four stages of strain ageing: (i) the pinning by solute atoms of dislocations generated during pre-strain, (ii) the generation of fresh dislocations from grain boundaries, (iii) the onset of precipitation and, (iv) the inhibition of dislocation generation from grain boundaries due to pinning by carbon segregation. On the other hand, the chromium containing steels only exhibit the fIrst three stages of strain ageing. An approximately twofold …

Effects Of Salinity And Sand Content On Liquid Limit And Hydraulic Conductivity, Behzad Fatahi, Mohammad Hadi Khabbaz, Sudip Basack
Faculty of Engineering and Information Sciences - Papers: Part A
Soil conditions of construction sites have become worse than ever due to the overpopulation in the metropolitan areas throughout the world. Likewise, the prevention of environmental risks due to individual activities is one of the most important subjects in the geo-environmental problems. Saline soils may induce several problems in geotechnical engineering projects such as infrastructure embankments, road construction and clay liners. Effect of the various concentrations of sodium chloride (NaCl) on several different soils including bentonite, kaolinite and fine sand mixtures has been evaluated. In addition, influence of salinity and the period of submergence on the hydraulic conductivity of soil …

Background: The characterization of DNA replication origins in yeast has shed much light on the mechanisms of initiation of DNA replication. However, very little is known about the evolution of origins or the evolution of mechanisms through which origins are recognized by the initiation machinery. This lack of understanding is largely due to the vast evolutionary distances between model organisms in which origins have been examined.Results: In this study we have isolated and characterized autonomously replicating sequences (ARSs) in Lachancea kluyveri - a pre-whole genome duplication (WGD) budding yeast. Through a combination of experimental work and rigorous computational analysis, we …

Outcomes were participants' acceptance of the negative reinforcement explanation for smoking, positive outcome expectations for smoking, self-efficacy and urges to smoke reported at one …
Can Australia High Speed Rail Overcome It's Bumpy History?, Philip Laird
Can Australia High Speed Rail Overcome It's Bumpy History?, Philip Laird
Faculty of Engineering and Information Sciences - Papers: Part A
The Australian Government has released an "implementation" study for high speed rail (or HSR) on the east coast with a further study to follow. The proposal looks at corridors between Melbourne, Sydney and Brisbane. It includes the option of three-hour travel times between Sydney and Melbourne, with tickets costing around $100. With the projected price of the project starting at around $60 billion, and Australia's chequered history with HSR, it is not unreasonable to ask whether the project will commence. In this case, would Sydney to Newcastle take preference over Sydney to Melbourne?

Cavity Enhanced Stimulated Brillouin Scattering In An Optical Ship For Multiorder Stokes Generation, Ravi Pant, Enbang Li, Duk-Yong Choi, Christopher Poulton, Stephen J. Madden, Barry Luther-Davies, Benjamin J. Eggleton
Faculty of Engineering and Information Sciences - Papers: Part A
We report the first demonstration of on-chip cascaded stimulated Brillouin scattering (SBS). Cascaded SBS is characterized in a 4 cm long chalcogenide ( As2S3 ) rib waveguide where the end facet reflections provide a monolithic Fabry–Perot (FP) resonator. The presence of the FP cavity reduces the Brillouin gain threshold, which enables observation of cascaded SBS at reduced pump powers. We observe up to three orders of Stokes waves in the backscattered signal at a coupled peak power of 1.34 W . Anti-Stokes waves due to four-wave mixing between the pump and the Stokes wave were observed in the forward spectrum.

Terahertz-Wave Parametic Oscillator With Misalignment-Resistant Tuning Cavity, Bo Sun, Sanxing Li, Jinsong Liu, Enbang Li, Jianquan Yao
Faculty of Engineering and Information Sciences - Papers: Part A
We demonstrate a terahertz-wave parametric oscillator (TPO) with a corner-cube resonator consisting of a corner-cube prism (CCP) and a flat mirror. By using the cavity configuration proposed in this Letter, the generation of tunable monochromatic terahertz (THz) waves can be achieved just by rotating the flat mirror instead of rotating the TPO cavity relative to the pump beam. The THz-wave output intensity and pulse width can be controlled periodically by rotating the CCP around the cavity axis. The TPO stability against cavity misalignment is significantly improved by at least 1 to 2 orders of magnitude compared with the conventional plane–parallel …
Enhanced Gas Drainage From Undersaturated Coal Bed Methane Reservoirs, Dennis John Black, Naj Aziz, Ting Ren
Enhanced Gas Drainage From Undersaturated Coal Bed Methane Reservoirs, Dennis John Black, Naj Aziz, Ting Ren
Faculty of Engineering and Information Sciences - Papers: Part A
Traditional methods of coal seam gas drainage rely on the use of reservoir pressure reduction to promote gas desorption from the coal matrix. Studies in coal mining gas drainage operations, particularly in coal seams that are deeply undersaturated and have low permeability, found the rate of reservoir pressure reduction was prohibitively slow. In such conditions, lengthy production delays have been experienced while additional gas drainage drilling is undertaken in an attempt to reduce seam gas content below specified threshold limits. Such drilling represents a high additional operating cost and yields low total gas production whilst adversely impacting the mine's gas …

An Analytical Method For Predicting Cogging Forces In Linear Induction Motors, Mochammad Rusli, Jeffrey W. Moscrop, Donald Platt, Christopher David Cook
Faculty of Engineering and Information Sciences - Papers: Part A
Cogging in a linear machine can be described as a variation in the magnetic forces as the machine travels along its linear uis. This effect can have a severe impact on the overall precision and even stability of the linear uis. In this paper an analytical method to predict the cogging forces in Linear Induction Moton (LIMs) is presented. An aecurate estimation of cogging is useful during the LIM design stage to help millimize this performance limiting factor. One common method used to predict cogging torques in rotary induction moton is the tooth overlap method. Due to the complexity of …

Faculty of Engineering and Information Sciences - Papers: Part A
The important factor disturbing the modern power systems today is load flow control. The Unified Power Flow Controller (UPFC) is an effective way for controlling the power flow and can provide damping capability during transient conditions. The UPFC is controlled conventionally using PI controller. This paper presents two robust controllers to improve the performance of the UPFC. The first is a RST controller based on the principle of pole placement and the second is an intelligent controller based on the principle of fuzzy logic optimized by Genetic Algorithm (GA).

Offline Programming For Short Batch Robotic Welding, Nathan Larkin, Aleksandar Milojevic, Zengxi Pan, Joseph Polden, John Norrish
Faculty of Engineering and Information Sciences - Papers: Part A
Robotics based automation has many advantages over both manual operation and dedicated hard automation. In practice however the robot programming overhead and high cost of dedicated jigging are serious impediments to its use for short production runs. Offline programming packages offer an attractive alternative to reduce programming time and robot down time, however many of the available packages are fairly complex and treat the geometric programming and welding operation separately. The paper will describe the development of alternative approaches and the evaluation of an integrated offline robotic welding package (RinasWeld) which addresses these issues and makes low volume robotic welding …

The main objective of these notes is to give some intuition about spectral triples and the role they play in index theory. The notes are basically a road map, with much detail omitted. To give a complete account of all the topics covered would require at least a book, so we have opted for a sketch.
An Opportunistic Scheduler For Dense Wlans, Kwan-Wu Chin
An Opportunistic Scheduler For Dense Wlans, Kwan-Wu Chin
Faculty of Engineering and Information Sciences - Papers: Part A
The demand for bandwidth by multimedia applications remains unabated. This is particular critical given the growing number of devices with WiFi capability, and the ubiquity of Wireless Local Area Networks (WLANs). These trends have spurred researchers to develop low-cost and backward compatible solutions to increase the capacity of WLANs. One approach is to deploy additional Access Points (APs), and strategies to manage channel, user, and transmit power. As a result, stations are likely to be near one or more APs, and therefore are more likely to experience high data rates. In this paper, we take advantage of this fact to …
