An Intelligent User Interface For Browsing And Search Mpeg-7 Images Using Concept Lattices, Jon R. Ducrou, Peter W. Eklund, T. Wilson Jan 2006

An Intelligent User Interface For Browsing And Search Mpeg-7 Images Using Concept Lattices, Jon R. Ducrou, Peter W. Eklund, T. Wilson

This paper presents the evaluation of a design and architecture for browsing and searching MPEG-7 images. Our approach is novel in that it exploits concept lattices for the representation and navigation of image content. Several concept lattices provide the foundation for the system (called Image-Sleuth) each representing a different search context, one for image shape, another for color and luminance, and a third for semantic content. This division of information aids in the facilitation of image browsing based on a metadata ontology. The test collection used for our study is a sub-set of MPEG-7 images created from the popular The ...


An Interactive Learning Environment For Teaching Statistics, Trevor Spedding, Xuesong Chi Jan 2006

This paper outlines the development and use of a web based virtual factory simulator for teaching industrial statistics and process improvement techniques. Students can manage the factory for either a period of one month, or the length specified by lecturers, with the factory running in real time. The main objective is to reduce quality problems and continuously improve the quality over a substantial period of time. Techniques such as control charts, process capability, experimental design and response surface methodology and their underlying statistics are explored. This immersive simulation creates a problem-based learning approach with relevant academic underpinning. It provides the ...


Testing For Structural Breaks In The Korean Economy 1980-2005: An Application Of The Innovational Outlier And Additive Outlier Models, Charles Harvie, Mosayeb Pahlavani Jan 2006

Testing For Structural Breaks In The Korean Economy 1980-2005: An Application Of The Innovational Outlier And Additive Outlier Models, Charles Harvie, Mosayeb Pahlavani

This paper employs quarterly time series data to endogenously determine the timing of structural breaks for various macroeconomic variables in the Korean economy. The Innovational Outlier (IO) as well as Additive Outlier models (Perron, 1997) are then used to test for non-stationarity of the Korean macroeconomic data. After accounting for the single most significant structural break the results from the (AO) model clearly indicate that the null o f a unit root cannot be rejected for all of the series under investigation. This finding is consistent with our finding based on the conventional unit root test. However, by applying the ...


Students' Preference For Teaching Strategies That Strengthen The Learning Of Economics In Middle Eastern Universities, Mokhtar M. Metwally, Nelson Perera Jan 2006

A survey, covering a random sample of 139 students, was conducted at the University of Wollongong in Dubai during the months of September-November 2004, to gather opinions of students about their attitudes towards strategies that promote the teaching and learning of economics The technique of factor analysis was used to model the preference of students for various strategies. Multiple discriminant analysis was used to find out whether there are any significant differences in the attitudes of students at different stages :"students learning introductory economic subjects", "students learning intermediate economic subjects" and "students learning advanced and applied economic subjects" Factor scores ...

Knowledge Managament for the provision of Health Information Services is a developing field and one that is usefully informed by applied research. The current study is conducted with Intensive Care Unit (ICU) professionals to capture and distil their views in regard to a developing a Web-Based Information Service. This service is provided by a central coordination and monitoring unit for intensive care units across NSW, Australia. The study is part of a larger research initiative that is being done to advance the provision of health information in ICU's across the state. Given the complex and dynamic context of ICUs ...


Structuring The Project Environment For Learning, Andrew J. Sense Jan 2006

Structuring The Project Environment For Learning, Andrew J. Sense

Faculty of Commerce - Papers (Archive)

This paper argues that project learning and the learning competency development of project practitioners are most appropriately pursued through the creation and maintenance of supportive situated learning environments within projects. Drawing on participative action research into learning practices within a case study project involving organizational change, this paper introduces a model of project situated learning behaviour and identifies and explains five sociological elements (barriers or enablers) that are primal in shaping the learning behaviours of project team participants. This framework facilitates practitioners’ systematic and communal reflection on their learning practices and helps develop their skills in ‘learning how to learn’.


Overcoming Organisational Resistance To Using Wiki Technology For Knowledge Management, Charmaine C. Pfaff, Helen M. Hasan Jan 2006

Overcoming Organisational Resistance To Using Wiki Technology For Knowledge Management, Charmaine C. Pfaff, Helen M. Hasan

Although Wikis emerged in the public domain more than a decade ago, a number of business organisations are now discovering the advantages of using Wiki technology to manage knowledge. However, there are many who are not convinced about the merits of this relatively new Wiki technology and are not yet prepared to risk its adoption because it exhibits many ideas that have yet to be tested and many issues that have yet to be resolved. This paper studies the merits of using a Wiki for knowledge management. While some cases of corporate adoption of Wiki technology have been reported, cases ...

Management flight simulators provide a “microworld” in which users control an organization in a realistic environment without the need to disturb the real system. This paper presents a web-based intelligent virtual learning environment to enhance the education of engineering management students in quality management and statistical process control techniques. The paper introduces the structure and methodology for building this online learning environment. The simulated environment is based on an innovative approach which incorporates a Fuzzy Adaptive Resonance Theory Neural Network to enable students to obtain the best response by automatically identifying out of control conditions.
