Energy Analysis Of Net Zero Energy Buildings: A Case Study, Joel Anderson, Duane A. Robinson, Zhenjun Ma
Faculty of Engineering and Information Sciences - Papers: Part A
The building sector is a significant contributor to global energy usage and environmental emissions. Advanced building design, optimal selection and sizing of building components, and energy efficient operation are among the key ways of significantly reducing overall building energy demand. Achieving reduction in energy demand is a key directive of the net zero energy building concept. Building designs dedicated to meeting net zero energy building requirements are becoming more commonplace as a path towards reducing the overall emissions from the built environment. This work analyses the energy demand of a net zero energy office building and compares it with a …

Developing An Optimum Maintenance Policy By Life Cycle Cost Analysis - A Case Study, Khaled O. El-Akruti, Tieling Zhang, Richard Dwight
Faculty of Engineering and Information Sciences - Papers: Part A
This paper focuses on developing maintenance policies for critical assets to improve the production performance based on life cycle cost (LCC) analysis. A general approach is adopted for conducting the LCC analysis. The investigation is based on a case study to demonstrate how an optimum maintenance policy is determined. The relevant LCC structure in the case study is defined for the decision process which involves determination of the optimum life, repair limit and selection of materials, and trade-off between repair and replacement. The LCC analysis is based on statistical data modelling which facilitates decision-making on the optimal replacement of an …

Learning Network Storage Curriculum With Experimental Case Based On Embedded Systems, Qingguo Zhou, Jiong Wu, Ting Wu, Jun Shen, Rui Zhou
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper, we present an experimental case for the course of "Network Storage and Security," which benefited from an improved learning outcome for our students. The newly designed experiments-based contents are merged into the current course to help students obtain practical experiences about network storage. The experiments aim to build a network storage system based on available resources instead of any specialized network storage equipment. Technically, students can learn general practical knowledge of network storage on iSCSI (a network storage protocol based on IP technology) and also the technologies of embedded system. Through the experimental case, we found that …

Plans were compared using dose-volume histograms (DVH) and dose …
On The Uniqueness Of Lp-Minkowski Problems: The Constant P-Curvature Case In R^3, Yong Huang, Jiakun Liu, Lu Xu
On The Uniqueness Of Lp-Minkowski Problems: The Constant P-Curvature Case In R^3, Yong Huang, Jiakun Liu, Lu Xu
Faculty of Engineering and Information Sciences - Papers: Part A
We study the C4 smooth convex bodies K ⊂Rn+1 satisfying K(x) =u(x)1−p, where x ∈Sn, K is the Gauss curvature of ∂K, u is the support function of K, and p is a constant. In the case of n =2, either when p ∈[−1, 0] or when p ∈(0, 1) in addition to a pinching condition, we show that K must be the unit ball. This partially answers a conjecture of Lutwak, Yang, and Zhang about the uniqueness of the Lp-Minkowski problem in R3. Moreover, we give an explicit pinching constant depending only on p when p ∈(0, 1).
A Coastal Groundwater Management Model With Indian Case Study, Sudip Basack, Amartya Kumar Bhattacharya, Prabir Maity
A Coastal Groundwater Management Model With Indian Case Study, Sudip Basack, Amartya Kumar Bhattacharya, Prabir Maity
Faculty of Engineering and Information Sciences - Papers: Part A
The complexity of the hydrogeological setup in coastal areas calls for the adoption of scientific groundwater management techniques. Excessive withdrawal of groundwater in coastal zones will lead to depression of the water table, with associated hazards such as putting the well out of use, rendering abstraction uneconomic with increased lift. A sustained regional groundwater drawdown below sea level runs the risk of saline water intrusion, even for confined coastal aquifers. Uncontrolled groundwater development may lead to reversal of the freshwater gradient, thereby resulting in saline water ingress into coastal aquifers. There are, however, several established methodologies to control and minimise …

Faculty of Engineering and Information Sciences - Papers: Part A
Open data initiatives are critical to open government policies which promote transparency, citizen engagement and collaboration. However, they face challenges in realizing their potential benefits through citizens' active engagement. Despite the sharp rise of social media use by governments or quasi-governmental organizations to engage citizens in transforming public service quality and offers, very little has been written on enabling roles of social media in influencing the outcome of open data initiatives. This research examines the potential enabling roles of social media in motivating and having citizens' engagement easier in open data environments. Specifically, we present social media use in supporting …

The cloud adoption strategy realisation requires concrete guidelines and a comprehensive practical framework. This paper proposes the use of an agile enterprise architecture framework to developing and implementing the adaptive cloud technology-enabled enterprise architecture in the Australian government context. The results of this paper indicate that a holistic strategic agile enterprise architecture approach seems appropriate to support the strategic whole-of-a-government …
Case Studies On Response Of Laterally Loaded Nonlinear Piles, Wei Dong Guo
Case Studies On Response Of Laterally Loaded Nonlinear Piles, Wei Dong Guo
Faculty of Engineering and Information Sciences - Papers: Part A
Closed-form solutions for laterally loaded free and fixed-head piles in elastic-plastic media have been developed and implemented into a spreadsheet program called GASLFP. Underpinned by a generic limiting force profile (LFP), the solutions offer an expeditious and sufficiently accurate method for predicting response of lateral piles. They also allow parameters to be deduced using measured pile response, as is evident in the study to date on -70 test (elastic) piles. The solutions also well capture the impact of structure nonlinearity of pile body by employing reduced pile bending stiffness (EpIp). The law of the reduction in EpIp, however, needs to …

Faculty of Engineering and Information Sciences - Papers: Part A
The modelling of complex workflows is an important problem-solving technique within healthcare settings. However, currently most of the workflow models use a simplified flow chart of patient flow obtained using on-site observations, groupbased debates and brainstorming sessions, together with historic patient data. This paper presents a systematic and semi-automatic methodology for knowledge acquisition with detailed process representation using sequential interviews of people in the key roles involved in the service delivery process. The proposed methodology allows the modelling of roles, interactions, actions, and decisions involved in the service delivery process. This approach is based on protocol generation and analysis techniques …
Improving Online Banking Quality In Developing Nations: A Libyan Case, Fouad Elgahwash, Mark Freeman, Alison E. Freeman
Improving Online Banking Quality In Developing Nations: A Libyan Case, Fouad Elgahwash, Mark Freeman, Alison E. Freeman
Faculty of Engineering and Information Sciences - Papers: Part A
While the global banking sector is one of the most up-to-date industries with regard to the use of the Internet and mobile technologies, developing countries (such as Libya) have not broadly adopted these technologies. For example, online banking is not offered or provided on a restricted basis by many banks in Libya. As developing countries now seek to catch up with the global environment, both banks and customers are likely to face challenges. Understanding the perceptions of customers with regard to online banking quality in developing countries is useful for informing future adoption strategies and hence improving relationships between banks …

An Application Of Nonlinear Feature Extraction – A Case Study For Low Speed Slewing Bearing Condition Monitoring And Prognosis, Wahyu Caesarendra, Prabuono Buyung Kosasih, A K. Tieu, Craig Moodie
Faculty of Engineering and Information Sciences - Papers: Part A
This paper presents the application of four nonlinear methods of feature extraction in slewing bearing condition monitoring and prognosis: these are largest Lyapunov exponent, fractal dimension, correlation dimension, and approximate entropy methods. Although correlation dimension and approximate entropy methods have been used previously, the largest Lyapunov exponent and fractal dimension methods have not been used in vibration condition monitoring to date. The vibration data of the laboratory slewing bearing test-rig run at 1 rpm was acquired daily from February to August 2007 (138 days). As time progressed, a more accurate observation of the alteration of bearing condition from normal to …

An Investigation On The Impacts Of Density Currents On The Sedimentation In Dam Reservoirs Using Tcm Model; Case Study: Maroon Dam, Farhad Fakheri Raof, Mohammad Hossein Naghshine, Ali Khoshrftar
Faculty of Engineering and Information Sciences - Papers: Part A
Sedimentation in dams' reservoirs is one of the most pressing concerns facing dams today. Maroon reservoir dam, located in Khuzestan Province, is one of the most important dams in this region. Since it is a new constructed dam, numerical simulation of sedimentation trend in its reservoirs could significantly help on a better utilization. To this end, TCM model which is capable to simulate density currents was used. The obtained results show that the dam loses about 91 million m3 of its reservoirs during a 50-year exploitation period.
On The Correlation Between The Effectiveness Of Metamorphic Relations And Dissimilarities Of Test Case Executions, Yuxiang Cao, Zhi Quan Zhou, Tsong Yueh Chen
On The Correlation Between The Effectiveness Of Metamorphic Relations And Dissimilarities Of Test Case Executions, Yuxiang Cao, Zhi Quan Zhou, Tsong Yueh Chen
Faculty of Engineering and Information Sciences - Papers: Part A
Metamorphic testing (MT) is a property-based automated software testing method. It alleviates the oracle problem by testing programs against metamorphic relations (MRs), which are necessary properties among multiple executions of the target program. For a given problem, usually more than one MR can be identified. It is therefore of practical importance for testers to know the nature of good MRs, that is, which MRs are likely to have higher chances of revealing failures. To address this issue we investigate the correlation between the faultdetection effectiveness of MRs and the dissimilarity (distance) of test case execution profiles. Empirical study results reveal …
Evidence-Free Policy: The Case Of The National Injury Insurance Scheme, Mark Harrison
Evidence-Free Policy: The Case Of The National Injury Insurance Scheme, Mark Harrison
Faculty of Engineering and Information Sciences - Papers: Part A
The Productivity Commission report 'Disability Care and Support' recommends tort liability be replaced by a compulsory, government-run, no-fault scheme. But theory and evidence indicate moving to a no-fault scheme will increase the accident rate. Even a move from non-risk-rated third-party insurance to non-risk-rated first-party insurance reduces incentives for care. A no-fault scheme is not superior to current policies; genuine reform will need to be informed by law and economics literature.

Rail tracks are conventionally built on compacted ballast and structural fill embankments overlying the natural subsoil. Ballast plays an important role in providing track stiffness to support heavy traffic loads, and providing rapid drainage. However, ballast deforms and degrades progressively under the heavy cyclic loading of passenger and freight trains, which may lead to a loss of track geometry, and require costly regular maintenance. In particular, track construction requires appropriate stabilization techniques for ballast, the extent of which depends also on the type of subgrade. Comprehensive field trials were carried out on two rail lines in Bulli and recently in …

Dynamic Characteristics Of A Hybrid Microgrid With Inverter And Non- Inverter Interfaced Renewable Energy Sources: A Case Study, A V. Jayawardena, L G. Meegahapola, S Perera, D A. Robinson
Faculty of Engineering and Information Sciences - Papers: Part A
Microgrids are becoming important constituents of electric power distribution networks. Microgrids are typically comprised of both inverter interfaced (e.g. double-fed induction generator (DFIG), solar-photovoltaic (PV) system) and non-inverter interfaced (e.g. synchronous generator) renewable energy generators (REGs), hence their dynamic characteristics are significantly different from the conventional grids comprised of centralised synchronous generators. Different inherent characteristics of REGs, power dispatch levels, relative REG capacities, and external grid characteristics are some of the important features of significant interest in relation to microgrid dynamic behaviour. For this study a microgrid model was developed in DIgSILENT Power Factory based on the IEEE-13 bus system …
Enterprise Soa Implementation Readiness: A Case Study In Malaysia, Mahshitah Abdul Manan, Peter Hyland
Enterprise Soa Implementation Readiness: A Case Study In Malaysia, Mahshitah Abdul Manan, Peter Hyland
Faculty of Engineering and Information Sciences - Papers: Part A
Many vendors have acclaimed Service Oriented Architecture (SOA) as a better way to design and build enterprise-wide software. While these claims may be true in the private sector, there is scant evidence in the literature for the same success in the public sector. The adoption of SOA as the dominant development paradigm within an organisation often requires significant organisational changes, which are difficult to achieve in the public sector, with its strict hierarchies and departmental independence. Indeed, many government departments are not ready to adopt this new paradigm. However, the literature does not provide a suitable SOA readiness framework for …

Faculty of Engineering and Information Sciences - Papers: Part A
The updated ISO 13790 Standard is part of the new set of CEN Standards that supports the European Energy Performance of Buildings Directive (EPBD) requirement for a general framework for calculation of the energy consumption of buildings. The Standard sets out procedures for space heating and cooling energy calculations, allowing the use of three different methods: a simplified monthly quasi-steady state method, a simple-hourly method and detailed simulation. This paper examines the implications of allowing different methods to be used for assessing the energy usage. The research method used was to undertake a comparison of the various methods applied to …

Slope Instability, Hazard And Risk Associated With A Rainstorm Event - A Case Study, Phillip N. Flentje, Robin N. Chowdhury
Faculty of Engineering and Information Sciences - Papers: Part A
Over the last few decades there has been an increasing awareness of landslide hazard and risk in many coastal regions of Australia. Urban communities in hilly areas are, from time to time, adversely affected by rainfall-induced landsliding. However, acute awareness of hazard may be absent during periods between significant rainstorm events. In general, the serious consequences of landslides to property and life have been underestimated in Australia. It is now known that at least 80 deaths can be attributed to a number of landslides (Leiba, 1998). Some of these events have focussed the attention of the public, the most important …
