Lie Group Symmetry Analysis Of Transport In Porous Media With Variable Transmissivity, James Hill, Maureen Edwards, A P S Selvadurai
Lie Group Symmetry Analysis Of Transport In Porous Media With Variable Transmissivity, James Hill, Maureen Edwards, A P S Selvadurai
Dr Maureen Edwards
We determine the Lie group symmetries of the coupled partial differential equations governing a novel problem for the transient flow of a fluid containing a solidifiable gel, through a hydraulically isotropic porous medium. Assuming that the permeability ($K^*$) of the porous medium is a function of the gel concentration ($c^*$), we determine a number of exact solutions corresponding to the cases where the concentration-dependent permeability is either arbitrary or has a power law variation or is a constant. Each case admits a number of distinct Lie symmetries and the solutions corresponding to the optimal systems are determined. Some typical concentration …

Interactive Effects Of Networked Publics And Social Media On Transforming The Public Sphere: A Survey Of Iran's Leaderless 'Social Media Revolution', Akemi Chatfield, Hans Scholl, Reza Akbari, Nima Mirzayi
Interactive Effects Of Networked Publics And Social Media On Transforming The Public Sphere: A Survey Of Iran's Leaderless 'Social Media Revolution', Akemi Chatfield, Hans Scholl, Reza Akbari, Nima Mirzayi
Dr Akemi Chatfield
It has been argued that hierarchical 'command and control' leadership is required to coordinate massive and rapid military or disaster response. Against this, the concept of leaderless 'social media revolution' refers to the wide-spread use of Web 2.0 social media by ordinary citizens to transform the public sphere and engage in collective political action, including coordinating massive and rapid protests against government. However, conceptual and empirical research efforts remain scarce to date. This research draws on the emergent perspective on causal agency in effecting change in social systems to examine our research proposition that the interactive effects of networked publics …
The Impact Of Rfid Technology On Warehouse Process Innovation: A Pilot Project In The Tpl Industry, Samuel Fosso Wamba, Akemi Chatfield
The Impact Of Rfid Technology On Warehouse Process Innovation: A Pilot Project In The Tpl Industry, Samuel Fosso Wamba, Akemi Chatfield
Dr Akemi Chatfield
Using the value chain model which provides a process view, this longitudinal case study and simulation modeling analysis of a Canadian third-party logistics (TPL) supply chain provides some empirical support for the enabling role of RFID technology in effecting warehouse process innovation and optimization for the focal TPL firm. However, the findings of our study also reveal the RFID technology implementation costs as the key inhibitor of RFID widespread adoption and usage among suppliers. This, in turn, precluded the focal TPL firm from implementing the best optimum RFID solution to create better business value from the RFID project.
Two Families Of Exel-Larsen Crossed Products, Nathan Brownlowe, Iain Raeburn
Two Families Of Exel-Larsen Crossed Products, Nathan Brownlowe, Iain Raeburn
Dr Nathan Brownlowe
Larsen has recently extended Exel’s construction of crossed products from single endomorphisms to abelian semigroups of endomorphisms, and here we study two families of her crossed products. First, we look at the natural action of the multiplicative semigroup N× on a compact abelian group Γ , and the induced action on C(Γ ). We prove a uniqueness theorem for the crossed product, and we find a class of connected compact abelian groups Γ for which the crossed product is purely infinite simple. Second, we consider some natural actions of the additive semigroup N2 on the UHF cores in 2-graph algebras, …
An Application Of The 5-S Activity Theoretic Requirements Method, Robert Brown, Peter Hyland, Ian Piper
An Application Of The 5-S Activity Theoretic Requirements Method, Robert Brown, Peter Hyland, Ian Piper
Dr Robert Brown
One of the most crucial aspects of highly interactive, multi-user, organisational systems is the interface. The Human Computer Interaction (HCI) community has not adopted rigorous Formal Methods with open arms (Paterno, 1996). However, the HCI community has widely adopted Usability Engineering approaches (Corporate Solutions 2006), such as Nielsen’s (1994), which offers considerable formality. There remains, however, scope for user interface (UI) design to adopt a theoretical framework to enhance consistency across the whole design and development lifecycle. A theoretically-consistent framework from initial conceptual elicitation to evaluation of the finished product may prove useful. Since the aim of UI design is …
Incremental Acquisition Of Search Knowledge, Ghassan Beydoun, Achim Hoffmann
Incremental Acquisition Of Search Knowledge, Ghassan Beydoun, Achim Hoffmann
Associate Professor Ghassan Beydoun
The development of highly e!ective heuristics for search problems is a di$cult and time-consuming task. We present a knowledge acquisition approach to incrementally model expert search processes. Though, experts do not normally have complete introspective access to that knowledge, their explanations of actual search considerations seem very valuable in constructing a knowledge-level model of their search processes.
Design Of A P2p Information Sharing Mas Using Mobmas, Numi Tran, Ghassan Beydoun, Graham Low
Design Of A P2p Information Sharing Mas Using Mobmas, Numi Tran, Ghassan Beydoun, Graham Low
Associate Professor Ghassan Beydoun
Most existing agent-oriented methodologies ignore system extensibility, interoperability and reusability issues. In light of this, we have developed MOBMAS – a “Methodology for Ontology-Based MASs” which makes use of ontologies as a central modeling tool, utilising their roles in facilitating interoperability and reusability. As part of an ongoing validation of MOBMAS, we demonstrate in this paper its use on a peer-to-peer (P2P) community-based information sharing application. MOBMAS is used by an experienced software developer, who is not an author of the methodology, to guide the development of the P2P application.
Development Of A Peer-To-Peer Information Sharing System Using Ontologies, Ghassan Beydoun, Graham Low, Numi Tran, Paul Bogg
Development Of A Peer-To-Peer Information Sharing System Using Ontologies, Ghassan Beydoun, Graham Low, Numi Tran, Paul Bogg
Associate Professor Ghassan Beydoun
Most existing agent-oriented methodologies ignore system extensibility, interoperability and reusability issues. Ontologies have been found to play a significant role in facilitating interoperability, reusability, MAS development activities (including MAS analysis and agent knowledge modeling) and MAS run-time operation (including agent communication and reasoning). However, most of the existing AOSE methodologies do not provide support for ontology-based MAS development. We present software engineering requirements for ontology-based development for MAS and examine an existing methodology, MOBMAS - a "Methodology for Ontology-Based MASs", which makes use of ontologies as a modeling tool. In this examination, we highlight how MOBMAS can be extended to …

Towards Agent-Oriented Approach To A Call Management System, Amir Ashamalla, Ghassan Beydoun, Graham Low
Associate Professor Ghassan Beydoun
There is more chance of a completed sale if the end customers and relationship managers are suitably matched. This in turn can reduce the number of calls made by a call centre reducing operational costs such as working time and phone bills. This chapter is part of ongoing research aimed at helping a CMC to make better use of its personnel and equipment while maximizing the value of the service it offers to its client companies and end customers. This is accomplished by ensuring the optimal use of resources with appropriate real-time scheduling and load balancing and matching the end …
Theoretical Basis For Hierarchical Incremental Knowledge Acquisition, Ghassan Beydoun, Achim Hoffmann
Theoretical Basis For Hierarchical Incremental Knowledge Acquisition, Ghassan Beydoun, Achim Hoffmann
Associate Professor Ghassan Beydoun
Human experts tend to introduce intermediate terms in giving their explanations. The expert's explanation of such terms is operational for the context that triggered the explanation; however, term de"nitions remain often incomplete. Further, the expert's (re) use of these terms is hierarchical (similar to natural language). In this paper, we argue that a hierarchical incremental knowledge acquisition (KA) process that captures the expert terms and operationalizes them while incompletely de"ned makes the KA task more e!ective. Towards this we present our knowledge representation formalism Nested Ripple Down Rules (NRDR) that is a substantial extension to the (Multiple Classi"cation) Ripple Down …

Quantification Of Emission Reduction From Electricity Network With The Integration Of Renewable Resources, M. Abdullah, A. Agalgaonkar, K. Muttaqi
Quantification Of Emission Reduction From Electricity Network With The Integration Of Renewable Resources, M. Abdullah, A. Agalgaonkar, K. Muttaqi
Dr Ashish Agalgaonkar
Integration of renewable energy resources into the electricity network is one of the strategies for overall emission reduction in the network. The quantification of emission offset from renewable distributed generation (DG) needs to be incorporated in planning to assess the effectiveness of integrating these resources from emission reduction perspective. In this paper, a numerical method is proposed for quantifying the emission reduction from distribution network with the integration of renewable resources by examining the coincident hours between the time varying nature of load and generation. The factors influencing annual emission reduction are also identified along with the use of energy …

Investigating The Operation Of Multiple Voltage Regulators And Dg In A Distribution Feeder, Dothinka Ranamuka, A Agalgaonkar, K Muttaqi
Dr Ashish Agalgaonkar
Integration of distributed generation (DG) in a distribution network may introduce adverse effects including control interaction, oscillatory transients and operational conflicts. This paper investigates the operation of multiple voltage regulators such as on-load tap changer (OLTC) and step voltage regulator (SVR), and DG in a medium voltage distribution feeder. Investigations have been carried out using time domain simulation studies conducted using MATLAB-SimPowerSystems. The results are reported for a case study involving radial distribution feeder, derived from New South Wales (NSW) electricity distribution network in Australia.
Optimal Allocation Of Renewable Enegy Resources For Minimising Emissions In The Distribution Network, M. Abdullah, A. Agalgaonkar, K. Muttaqi
Optimal Allocation Of Renewable Enegy Resources For Minimising Emissions In The Distribution Network, M. Abdullah, A. Agalgaonkar, K. Muttaqi
Dr Ashish Agalgaonkar
Integration of renewable Distributed Generation (DG) into the distribution networks is one of the effective ways to ensure emission reduction with the added benefits of network support and transmission and distribution system expansion deferral. Emission reduction by renewable DGs mostly depends on the generation technology, size and type of DG units and curtailment of fossil fuel based grid energy. This paper proposes a strategy for evaluating the size and type of renewable DG and determining the best mix of different renewable DG technologies by minimising primary and operational emissions without violating network constraints. A methodology based on time sequential optimisation …

Methods To Evaluate Health Information Systems, Ping Yu, Hui Yu, Jeffrey Soar
Dr Ping Yu
To ensure the introduction of a health information system (HIS) is on track and will bring in the ex-pected outcomes, it is essential to evaluate the critical success factors at every stage of the system introduction life cy-cle. Based on comprehensive literature research and personal experience of evaluating HIS, the author proposes a multi -method approach that incorporates both quantitative and qualitative research, conceptualized through the DeLone and McLean Information Systems Success Model. The advantage of this approach is not only identifying the factors impacting on implementation success, but also distinguishing the critical factors from the less important ones.Thus it …

Challenges To The Adoption Of Mobile And Wireless Technology In Australian Aged Care, Ping Yu, Hui Yu
Challenges To The Adoption Of Mobile And Wireless Technology In Australian Aged Care, Ping Yu, Hui Yu
Dr Ping Yu
The Australian aged-care industry, which is still in the early stages of adopting information technology (IT), is seeking methods for improving efficiency. New mobile and wireless technology may be relevant. As nurses are always moving around beds, wards and community care centres, a mobile solution might suit their documentation needs. To date, however, no convincing mobile and wireless technology has been implemented in health-care. In order to provide IT solutions that satisfy the business needs and work practices of aged-care nurses, a study on the barriers to the adoption of mobile and wireless solutions for aged care has been undertaken. …

An Exploration Of Aged Care Nurse's Readiness And Ability To Use It In Their Work - Outline Of A Proposed Research, Ping Yu, Patrick Crookes, Sunaina Lobo
Dr Ping Yu
Dramatic changes in health care have led to a major restructuring of clinical nursing practice. In addition to data processing functions, computers are being used for assisting nurse care delivery such as monitoring patients, scheduling, order entry and result reporting, preventing drug interactions by cross-referencing drug compatibilities and warning appropriate staff of potential risks. This research will mainly focus on investigating the perceptions of use of clinical IT by aged care nurses. Aged care nurses' acceptance and ability to use IT to conduct every day tasks will be investigated.

Design An Automatic Appointment System To Improve Patient Access To Primary Health Care, Hongxiang Hu, Ping Yu, Jun Yan
Dr Ping Yu
Advanced Access model has been introduced in general practice in the United States to improve patient access to primary health care services for more than ten years. It has brought in the benefits of eliminating service provider’s waiting lists, improving patients’ timely access to services and reducing no-show rate. However, to implement this model, practices need to collect relevant information, develop contingency plans and set up practice strategies to balance the provision of care and patient’s demand. These tasks are not always easy to achieve. Understanding the requirements and constraints for effective management of patient booking is essential for developing …
