Development And Application Of A System For The Analysis Of Atmospheric, Water And Sediment Nitrogen And Carbon, Ann Stavert, Stephen R. Wilson, Dianne F. Jolley

Faculty of Science - Papers (Archive)

Eutrophication and climate change, key environmental concerns, are both linked to the carbon and nitrogen cycles hence the improved understanding of these cycles is essential. Currently, there is no system that simultaneously measures the fluxes of the three key gas phase products of nitrogen and carbon cycling (CO2, CH4 and N2O) in submerged ecosystems with hourly time resolution. A “Lake-in-a-box” (mesocosm) was developed in the laboratory which allowed the monitoring of key components of the carbon and nitrogen cycles within the air, water and sediments. The approach is automated, simple and time efficient and novel in its ability to examine …


Amplified Voices, But They Are Speaking To The Wrong People. Why The Complaint System For Unacceptable Advertising In Australia Is Not Working, Katherine Eagleton, Sandra C. Jones Jan 2008

Amplified Voices, But They Are Speaking To The Wrong People. Why The Complaint System For Unacceptable Advertising In Australia Is Not Working, Katherine Eagleton, Sandra C. Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

This exploratory study highlights the lack of public awareness of the role of the Advertising Standards Board (ASB) in the process of handling complaints about unacceptable advertising in Australia. Results show that only a small proportion of Australian adults know that the ASB are the appropriate complaints handling body. This lack of awareness is evident even among those who have made a complaint about advertising (generally to a less appropriate body). This highlights the need for an education campaign to inform the general public how to make a complaint about inappropriate advertising, and who to make a complaint to. Empowering …


The Institutional Legacy And The Development Of An Australian National Innovation System, Simon Ville Jan 2007

The Institutional Legacy And The Development Of An Australian National Innovation System, Simon Ville

Faculty of Commerce - Papers (Archive)

Institutions are the rules of the game that help to shape the long-term historical development of societies. They mediate human interaction and can be more or less formal (or tangible) in nature ranging from systems of government to common modes of behaviour. Most formal institutions can be distinguished as economic, social, political or cultural in nature although such distinctions are more difficult to make for informal institutions. What is certain is the pervasive impact of all types of institutions on a country’s multifaceted development. Thus, economic performance may be shaped as much by a nation’s legal system as by its …


Conducting Polymers With Fibrillar Morphology Synthesized In A Biphasic Ionic Liquid/Water System, J.M. Pringle, Orawan Ngamna, Carol M. Lynam, Gordon G. Wallace, Maria Forsyth, Douglas Macfarlane Jan 2007

Conducting Polymers With Fibrillar Morphology Synthesized In A Biphasic Ionic Liquid/Water System, J.M. Pringle, Orawan Ngamna, Carol M. Lynam, Gordon G. Wallace, Maria Forsyth, Douglas Macfarlane

Faculty of Science - Papers (Archive)

The synthesis of poly(pyrrole), poly(terthiophene), and poly(3,4-ethylenedioxythiophene) with unusual fibrillar morphologies has been achieved by chemical polymerization in a biphasic ionic liquid/water system. Use of aqueous gold chloride as the oxidant, with the monomers dissolved in a hydrophobic ionic liquid, allows the polymerization to occur at the ionic liquid/water interface. The resultant conducting polymer fibrils are, on average, 50−100 nm wide and can be thousands of nanometers long. The polymers produced in this ionic liquid system are compared to those synthesized in a biphasic chloroform/water system.

Implementation Of An Integrated Accounting And Cost Management System Using Sap System: A Field Study, Sudhir C. Lodh, Michael J. Gaffikin

Faculty of Commerce - Papers (Archive)

Not only are in-depth (theoretically informed) longitudinal (reflexive) field studies few and far between, it has been argued in those studies that little is known about the design and implementation of accounting and information systems that operate in today's world-class organizations. Using such an approach this study seeks to illustrate and analyse the implementation processes of an integrated accounting and cost management system using the SAP system at a major steel producer in Australia. It is demonstrated that the technical design of the system is only a part of the implementation process. Keeping 'actor-networks' in line and managing change including …

Energy Storage System For Reduction Of Mid-Line Voltage Variation Of A Dfig Wnd Turbine Connected To A Weak Grid, M Aktarujjaman, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich Jan 2006

Energy Storage System For Reduction Of Mid-Line Voltage Variation Of A Dfig Wnd Turbine Connected To A Weak Grid, M Aktarujjaman, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich

Faculty of Engineering and Information Sciences - Papers: Part A

Penetration of wind power into electricity system is constantly increasing. Wind resources are usually distant from existing transmission lines. Wind farms are often connected to weak grids far from central generation stations. Maximum wind power extraction causes the more irregular and unpredicted power output of wind turbine, which has same nature as wind speed variation. The voltage in such long line is vulnerable with the consumption and generation imbalance. In a long line, the mid-line voltage is largely affected by the variation and the penetration of the wind fluctuating power. Fluctuating nature of wind power output and long transmission line …


Control Stabilisation Of An Islanded System With Dfig Wind Turbine, M Aktarujjaman, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich Jan 2006

Control Stabilisation Of An Islanded System With Dfig Wind Turbine, M Aktarujjaman, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich

Faculty of Engineering and Information Sciences - Papers: Part A

Distributed Generation (DG) is often used to export power to the utility system. Loss of main supply can cause a severe loading mismatch between DG generation and load consumption. Consequently, the voltage and frequency of the islanded system will cross the allowable limit. Due to this fact, it is essential to control the voltage and frequency in the islanding mode of operation. In this paper, control stabilisation of an islanded system with a doubly-fed induction generator (DFIG) wind turbine has been addressed. Wind DG produces variable output and is not capable to produce enough reactive power. Hence, it is imperative …

Specifying System Requirements Using The 5s Method, Robert B. K Brown, Peter Hyland, Ian C. Piper

Faculty of Engineering and Information Sciences - Papers: Part A

The 5S Method takes an Activity Theory approach to stakeholder elicitation. We interview stakeholders and build up a network of Activities according to Activity Theory precepts. These Activities are hierarchically decomposed into the smaller units of Action and Operation. This comprises a useful conceptual map of the human motivations and dependencies prior to insertion of the new computer based system. To identify and describe such a potential computer system, we analyse and identify linkages between the Activities and assemble a list of those which could usefully pass through such a computer system. Design decisions are driven and evaluated by reference …


Investigation Of Large-Scale Washover Of A Small Barrier System On The Southeast Australian Coast Using Ground Penetrating Radar, Brian G. Jones, C Bristow, Adam D. Switzer Jan 2006

Investigation Of Large-Scale Washover Of A Small Barrier System On The Southeast Australian Coast Using Ground Penetrating Radar, Brian G. Jones, C Bristow, Adam D. Switzer

Faculty of Science - Papers (Archive)

Prehistoric depositional signatures for large-scale washover involving marine inundation events such as storm and tsunami have been the subject of considerable research over the last 15 years. Much of this research has focused on the identification of sand sheets in back-barrier environments as depositional records for extreme washover events. All these deposits must have a sediment source, and by their nature, the most likely source of sediment for washover into back-barrier environments is the barrier itself. This study identifies an erosional signature for large-scale washover from a small coastal barrier on the southeast Australian coast. A distinct lense of marine …

Faculty of Commerce - Papers (Archive)

Most help desks have admitted their call volume has increased in the past decade while “help unavailable when needed” is the major reason for service delivery failure and user dissatisfaction. The habit of calling help desk for simple problems has prompted the investigation of transferring part of first-level troubleshooting duty from help desk to user. This research proposes the development of user self-help knowledge management system that allows user to solve simple and routine technical enquiries. The proposed approach incorporates software agent to allow autonomous handling of enquiries so that the most appropriate solution and user communication can be facilitated.

Implementation of Distributed Generation (DG) can improve power quality and reliability, and guarantee continuity of power supply. This paper addresses the issue of continuity of power supply especially for isolated communities. A part of a network can be electrically isolated from the main grid when the grid fails to supply power due to a fault in the network or unavailability of power generation. In this paper, a mini hydro-wind hybrid power system is considered, and operation and control of the hybrid system during connecting it with the grid as well as its operation in the isolated condition are investigated. The …

Science For Life: An Evaluation Of New Zealand's Health Research Investment System Based On International Benchmarks, Samuel Garrett-Jones, Tim Turpin, Brian Wixted

Faculty of Commerce - Papers (Archive)

During the past decade there have been major developments in the way that research investments have been monitored and evaluated. While there are differences in the ways governments fund research around the world, and a diversity of approaches to evaluation, there are a number of common themes that can be observed in national experiences. As the importance of evaluation increases, the gap between current practice and best practice becomes more significant, and the need for comparative study and methods development grows. Current international ‘better-practice’ approaches to research evaluation and performance indicators reflect two important considerations. First, they make a clear …

Faculty of Engineering and Information Sciences - Papers: Part A

In this work, glass formation under high-energy ball milling was investigated for a (Ti0.33Zr0.33Hf0.33)50(Ni0.33Cu0.33Ag0.33)40Al10 high-order alloy system with equiatomic substitution for early and late transition-metal contents. For comparison, an amorphous alloy ribbon with the same composition was prepared using the melt-spinning method as well. Structural features of the samples were characterized using x-ray diffraction, transmission electron microscopy, and differential scanning calorimetry. Mechanical alloying resulted in a glassy alloy similar to that obtained by melt spinning. However, the glass formation was incomplete, and a …


Intersection Type Systems And Logics Related To The Meyer-Routley System B+, Martin W. Bunder Jan 2003

Intersection Type Systems And Logics Related To The Meyer-Routley System B+, Martin W. Bunder

Faculty of Engineering and Information Sciences - Papers: Part A

Some, but not all, closed terms of the lambda calculus have types; these types are exactly the theorems of intuitionistic implicational logic. An extension of these simple (→) types to intersection (or →∧) types allows all closed lambda terms to have types. The corresponding →∧ logic, related to the Meyer–Routley minimal logic B+ (without ∨), is weaker than the →∧ fragment of intuitionistic logic. In this paper we provide an introduction to the above work and also determine the →∧ logics that correspond to certain interesting subsystems of the full →∧ type theory.

Faculty of Commerce - Papers (Archive)

This report provides a summary of current international experiences with financial incentives for supporting technology development and identifies some important implications for public policy in Thailand. International experiences have demonstrated the broader public good that can be achieved through policies and public interventions that stimulate technology learning environments built around clusters or networks of firms and national support institutions. Financial incentives serve as a mediating influence to enhance the flow of knowledge from firms that are closer to a leading technological edge through to those firms where technological skills are lagging. They are therefore an essential tool available to governments …

Power And Influence In Urban Planning: Community And Property Interests' Participation In Dublin's Planning System, Pauline M. Mcguirk Jan 1995

Power And Influence In Urban Planning: Community And Property Interests' Participation In Dublin's Planning System, Pauline M. Mcguirk

Faculty of Social Sciences - Papers (Archive)

Using local authority planning in Dublin as a case study. the extent and effectiveness of community and development interests' participation in policy formulation is examined. A primary locus is on the nature and timing of participation as a determinant of the relalive influence that each can exert over policy decisions. A critical distinction is drawn between formal and informal participation channels. The vast array of informal channels available to development interests can mean that they have little need to participate formally; thus a primary and secondary layer of influence on policy formulation can be distinguished. The primary layer is largely …
