A Sparse Implementation Of The Average Information Algorithm For Factor Analytic And Reduced Rank Variance Models, R Thompson, Brian Cullis, A Smith, Arthur Gilmour Dec 2012

A Sparse Implementation Of The Average Information Algorithm For Factor Analytic And Reduced Rank Variance Models, R Thompson, Brian Cullis, A Smith, Arthur Gilmour

Dr Arthur Gilmour

Factor analytic variance models have been widely considered for the analysis of multivariate data particularly in the psychometrics area. Recently Smith, Cullis & Thompson (2001) have considered their use in the analysis of multi-environment data arising from plant improvement programs. For these data, the size of the problem and the complexity of the variance models chosen to account for spatial heterogeneity within trials implies that standard algorithms for fitting factor analytic models can be computationally expensive. This paper presents a sparse implementation of the average information algorithm (Gilmour, Thompson & Cullis, 1995) for fitting factor analytic and reduced rank variance …


Design Of A P2p Information Sharing Mas Using Mobmas, Numi Tran, Ghassan Beydoun, Graham Low Dec 2012

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 Dec 2012

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 …


Methods To Evaluate Health Information Systems, Ping Yu, Hui Yu, Jeffrey Soar Dec 2012

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 …

A Cloud Based Information Integration Platform For Smart Cars, Yi Xu, Jun Yan Dec 2012

A Cloud Based Information Integration Platform For Smart Cars, Yi Xu, Jun Yan

Dr Jun Yan

Current in-car computers have limited processing capabilities, and the content in smart car applications is poor extension. Even more, tradition software install approach which was used in smart cars lacks neither economy nor convenience. To solve these issues, we introduced a Cloud based Information Integration Platform for Smart Cars that has the ability to encourage flexibility in smart cars and enhance the value of them. To achieve the smart control and information sharing in smart cars, the platform collects data on the CAN bus automatically, with the ability to process CAN bus messages in Clouds. The Smart Car Information Service …


A Study Of Information Security Awareness And Practices In Saudi Arabia, Abdulaziz Alarifi, Holly Tootell, Peter Hyland Dec 2012

A Study Of Information Security Awareness And Practices In Saudi Arabia, Abdulaziz Alarifi, Holly Tootell, Peter Hyland

Dr Holly Tootell

Although the Web, cell phoneand cloud computing put a world of information at our fingertips, that information is under constant threat from cyber vandals and hackers. While awareness of information threats is growing in the Western world, in places like Saudi Arabia, information security is very poor. Unlike Western pluralistic democracies, Saudi Arabia is a highly-censored country, with a patriarchical and tribal culture, which may influence its poor information security rating. This paper examines the level of information security awareness (ISA) among the general public in Saudi Arabia, using an anonymous online survey, based on instruments produced by the Malaysian …

Ontology-Driven Accounting Information System: Case Study Of The Stock Exchange Of Thailand, Jira Yammeesri, Seung Hwan Kang, S Lau

Dr Sim Kim Lau

Accounting information systems have improved conventional information control. Due to corporate meltdowns, corporate governance has come under greater scrutiny to improve practices of managing, retrieving and extracting accounting information within organizations. This paper introduces a framework for an ontology-driven accounting information system as a mean to share information in line of common agreement. The proposed approach contributes to weakening of asymmetric information and information transparency problems.
