Applying Formal Concept Analysis To Semantic File Systems Leveraging Wordnet, Benjamin Martin, Peter W. Eklund
Applying Formal Concept Analysis To Semantic File Systems Leveraging Wordnet, Benjamin Martin, Peter W. Eklund
Faculty of Health and Behavioural Sciences - Papers (Archive)
Formal Concept Analysis can be used to obtain both a natural clustering of documents along with a partial ordering over those clusters. The application of Formal Concept Analysis requires input to be in the form of a binary relation between two sets. This paper investigates how a semantic filesystem can be used to generate such binary relations. The manner in which the binary relation is generated impacts how useful the result of Formal Concept Analysis will be for navigating one’s filesystem.
Globalization And National Industrial Relations Systems: Theoretical Implications From The Singapore Case, Tan Ern Ser, Balakrishnan Parasuraman
Globalization And National Industrial Relations Systems: Theoretical Implications From The Singapore Case, Tan Ern Ser, Balakrishnan Parasuraman

In the 1960’s, Kerr and his associates (1973[1960]) — Dunlop, Harbison, and Myers— proposed the convergence thesis, which resonates with the “end of ideology” thesis propounded by Bell (1962). Not surprisingly, the thesis about the inevitability of societal convergence prompted some scholars to look for continuing diversity, an oft-cited prime example being Japan (Dore, 1973). Indeed, until the late 1980’s, Japan was still touted as a critical case which not only defied the convergence thesis, but could also serve as a growth model worthy of emulation by developing countries aspiring to First World living standards and, paradoxically, even developed countries …

the explicit and estimable HOGLEX demand system ( Tran Van Hoa, 1983, 1985 and Jerison and Jersion 1984) links for the first time an important aspect of economic theory and the statisticals of Box-Cox transformation analysis.
Implementing Systems In Complex Work Organisations, Wannapa Suratmethakul, Helen M. Hasan
Implementing Systems In Complex Work Organisations, Wannapa Suratmethakul, Helen M. Hasan
Faculty of Commerce - Papers (Archive)
This paper describes research on a case of the introduction, into a large educational institution, of a complex timetabling system that was already well established in other similar organisations. The research has used a grounded theory approach to reveal details within complex phenomena in an organisation when a substantial new system was implemented. The study revealed three critical issues: Knowledge Transfer, System Capability, and Organisational Context that appeared to be related to the problems of implementing the new information system in the organisation. This research adds to the understanding of a common situation where management have an over simplified view …
Systems Resemblance And Workpractice Evolution: Implications For Work Activity (Re)Design, Rodney J. Clarke
Systems Resemblance And Workpractice Evolution: Implications For Work Activity (Re)Design, Rodney J. Clarke
Faculty of Commerce - Papers (Archive)
This paper is concerned with addressing the question of how apparently disparate and unconnected systems can resemble each other. The question of what counts as a systems resemblance necessitates developing contextual workpractice descriptions associated with the systems features and ultimately entire systems. Using systemic semiotics an apparent ontogenetic convergence between entirely different systems is used to show that systems resemblance can be inferred when the constituent workpractices of information systems consist of comparable register features and especially if they exhibit comparable generic features. The implications of these findings for a new class of work activity (re)design practices are considered.

Executive Information Systems And The Top-Officers' Roles: An Exploratory Study Of User-Behaviour Model And Lessons Learnt, Emmanuel Ikart
Executive Information Systems And The Top-Officers' Roles: An Exploratory Study Of User-Behaviour Model And Lessons Learnt, Emmanuel Ikart
Faculty of Commerce - Papers (Archive)
In recent years a number of organisations have implemented executive information systems (EIS) in order to improve the performance of their executives’ jobs. Although the use of EIS is important in executives’ work, the majority of executives are unwilling to use EIS applications because of their design flaws. By using social factors, habits and facilitation condition variables from Triandis’ framework, this paper extends the Technology Acceptance Model (TAM) to derive useful variables to address the problem of the low usage of EIS by executives. This paper reports on research in progress in Australia on the adoption and usage of EIS …

This paper extends standard help system technology to demonstrate the suitability of Formal Concept Analysis in displaying, searching and navigating help content. The paper introduces a method for building suitable scales directly from the help system index by computing a keyword extension set. The keyword extension technique is generalisable in any document collection where a hand-crafted index of terms is available.
Energy Injection By Disbributed Generation For Enhancement Of Voltage Profile In Swer Systems, Kashem M. Muttaqi, Gerard Ledwich
Energy Injection By Disbributed Generation For Enhancement Of Voltage Profile In Swer Systems, Kashem M. Muttaqi, Gerard Ledwich
Faculty of Engineering and Information Sciences - Papers: Part A
A system with Distributed Generation (DG) has greater load carrying capacity and can correct for a poor voltage profile during peak loading. This paper addresses the loading patterns of rural feeders and the relative effectiveness of real and reactive injection to support voltage profile in Single Wire Earth Return (SWER) systems. Real and reactive injection on a SWER network has been investigated and required energy for voltage enhancement estimated. DG with real and reactive injection (DG-PQ) using Q priority (DG-QPQ) can drastically reduce fuel and energy requirements compared to the amount required by proportional use of real and reactive power …
Minimising Power Losses In Distribution Systems With Distributed Resources, An D. T Le, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich
Minimising Power Losses In Distribution Systems With Distributed Resources, An D. T Le, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich
Faculty of Engineering and Information Sciences - Papers: Part A
Attempts to reduce electricity cost, together with improving the efficiency of distribution systems, have led power utilities to dealing with the problem of power loss minimisation. Although losses in the system can never be entirely eliminated, they can be controlled and minimised in several ways. Research conducted in the last few decades has proven that an inclusion of Distributed Resources (DR) into distribution systems considerably lowers the level of power losses. Moreover, the choice of DR is even more attractive since it provides not only benefits in power loss minimisation, but also a wide range of other advantages including environment, …
Maximising Voltage Support In Distribution Systems By Distributed Generation, An D. T Le, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich
Maximising Voltage Support In Distribution Systems By Distributed Generation, An D. T Le, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich
Faculty of Engineering and Information Sciences - Papers: Part A
Rapidly increasing in the demand of electricity along with recently advances in distributed generation (DG) technologies have sparked a new interest in utilisation of DG sources. However, there are a number of technical issues regarding to the installation of DG, since DG connection significantly affects existing network configuration and operation, especially for system with high level of DG penetration. To achieve maximum voltage support from DG utilisation, methodologies related to DG placement and DG operation are developed in this paper. Technique to optimise voltage improvement by effectively injecting active and reactive power of DG is developed based on voltage sensitivity …
Dynamic Channel Allocation For Mobile Cellular Systems Using A Control Theoretical Approach, Yaya Wei, Chuang Lin, Raad Raad, Fengyuan Ren
Dynamic Channel Allocation For Mobile Cellular Systems Using A Control Theoretical Approach, Yaya Wei, Chuang Lin, Raad Raad, Fengyuan Ren
Faculty of Engineering and Information Sciences - Papers: Part A
The guard channel scheme in wireless mobile networks has attracted and is still drawing research interest owing to easy implementation and flexible control. Dynamic guard channel schemes have already been proposed in the literature to adapt to varying traffic load. This paper presents a novel control-theoretic approach to dynamically reserve guard channels called PI-Guard Channel (PI-GC) controller that maintains the handoff blocking probability (HBP) to a predefined value; while it still improves the channel resource utilization.
Eliciting And Specifying Requirements For Highly Interactive Systems Using Activity Theory, Robert B. K. Brown, Peter Hyland, Ian C. Piper
Eliciting And Specifying Requirements For Highly Interactive Systems Using Activity Theory, Robert B. K. Brown, Peter Hyland, Ian C. Piper
Faculty of Engineering and Information Sciences - Papers: Part A
The processes of eliciting user requirements and formalising these into specifications are critical for the success of highly interactive systems. These processes are still poorly understood, partly because current methods are usually ad hoc and lack any theoretical basis. A number of researchers have used Activity Theory (AT) to refine these processes and have met with some success. To date, this approach has been more useful explaining the processes post hoc. This positional paper proposes an AT method for requirement elicitation and specification definition. The method is sufficiently prescriptive and well formed that it does not require any detailed understanding …
Socio-Technical Systems: From Individual Transactions To Situated Community Activity, Helen M. Hasan
Socio-Technical Systems: From Individual Transactions To Situated Community Activity, Helen M. Hasan
Faculty of Commerce - Papers (Archive)
Although basic concepts of Activity Theory were articulated almost a century ago, they have stood the test of time and are proving to be appropriate for research into modem situation involving the use of socio-technical systems. Over the past decades the field of Information Systems has advanced from a focus on routine transaction processing systems to more sophisticated applications that support situated community activity. This chapter will describe how Activity Theory is becoming increasing relevant to these types of systems and can be complemented by other approaches such as Complexity Theory and a particular Knowledge Lens. Research is presented that …

Patterns of wave energy play a significant role in shaping the long-term structure of coral reef communities worldwide. For example, sections of reefs have been shown to vary greatly in morphology (dominant size class, growth form) as coral colonies adapt in response to local-scale differences in the wave heights typically experienced. These differences result in zonation (crest, lagoon, and slope), producing characteristic growth forms and species assemblages that vary in their vulnerability to damage from waves (Done 1993). Those communities experiencing the greatest typical wave energy align themselves parallel to the water flow, adopt stream-lined forms and are usually smaller …

Personal Response Systems Workshop, Brian Murphy, Ciorstan J. Smark
Faculty of Commerce - Papers (Archive)
Personal response systems (PRS) are known under several names. "Clickers"; "Audience Response Systems"; "Group Response Systems"; and "Classroom Performance Systems"; all of these are systems where the audience can respond to questions or give feedback to the presenter of a lecture or workshop whilst that presentation is taking place. This allows for immediate, and (if wished) anonymous feedback to the presenter and to the class.
