Myth Or Fact: Is Open Source Software More Secure Than Closed Source Software?, Daniel Saffioti, Gene Awyzio, Robert B. K. Brown
Myth Or Fact: Is Open Source Software More Secure Than Closed Source Software?, Daniel Saffioti, Gene Awyzio, Robert B. K. Brown
Associate Professor Daniel F. Saffioti
This paper examines one aspect of quality that organizations look for when selecting software, namely security. Studies over time have indicated that security; scalability, interoperability and flexibility are important however the major issue has always been support. This has led to the sometimes inflexible concept of Standard Operating Environments (SOEs) within organisations. Whilst SOEs provide many benefits to an organisation they can leave them vulnerable to several large security risks. CERT statistics show that security incidents have increased six fold since 2000 [1]. This paper will examine trends in both open and closed software development for a number of platforms …
A Cost-Effective Software Testing Strategy Employing Online Feedback Information, Zhiquan Zhou, Arnaldo Sinaga, Willy Susilo, Lei Zhao, Kai-Yuan Cai
A Cost-Effective Software Testing Strategy Employing Online Feedback Information, Zhiquan Zhou, Arnaldo Sinaga, Willy Susilo, Lei Zhao, Kai-Yuan Cai
Faculty of Engineering and Information Sciences - Papers: Part B
An online partitioning strategy is presented, in which test cases are selected based on feedback information collected during the testing process. The strategy differs from con- ventional approaches because the partitioning is performed online rather than off-line and because the partitioning is not based on program code or specifications. It can, therefore, be implemented in the absence of the source code or specification of the program under test. The cost-effectiveness of the proposed strategy has been empirically investigated with a set of subject programs, namely, SPACE, SED, GREP, and the Siemens Suite of Programs. The results demonstrate that the proposed …

Metamorphic Testing For Adobe Data Analytics Software, Darryl C. Jarman, Zhiquan Zhou, Tsong Yueh Chen
Metamorphic Testing For Adobe Data Analytics Software, Darryl C. Jarman, Zhiquan Zhou, Tsong Yueh Chen
Faculty of Engineering and Information Sciences - Papers: Part B
It is challenging to test data analytics software because a test oracle might not be available. This study reports our experience of applying metamorphic testing to Adobe's data analytics software that is used for anomaly detection in a set of time series data. We make use of geometric transformations to build metamorphic relations and generate simple time series data as the source test cases. The results of this study show that metamorphic testing is highly effective for both verification and validation purposes. An investigation of the issues detected during metamorphic testing revealed three bugs in the software under test.

Software Defined Intelligent Building, Rui Xue, Xin Huang, Jie Zhang, Yulin Lu, Ge Wu, Zheng Yan
Faculty of Engineering and Information Sciences - Papers: Part A
The networks of intelligent building are usually consist of a great number of smart devices. Since many smart devices only support on-site configuration and upgrade, and communication between devices could be observed and even altered by attackers, efficiency and security are two key concerns in maintaining and managing the devices used in intelligent building networks. In this paper, the authors apply the technology of software defined networking to satisfy the requirement for efficiency in intelligent building networks. More specific, a protocol stack in smart devices that support OpenFlow is designed. In addition, the authors designed the lightweight security mechanism with …

Stéphanie Corde
Purpose: The purpose of this study was to measure the dose distributions for different Radiation Oncology Physics and Engineering Services, Australia (ROPES) type eye plaques loaded with I-125 (model 6711) seeds using GafChromic R EBT3 films, in order to verify the dose distributions in the Plaque SimulatorTM (PS) ophthalmic 3D treatment planning system. The brachytherapy module of RADCALC R was used to independently check the dose distributions calculated by PS. Correction factors were derived from the measured data to be used in PS to account for the effect of the stainless steel ROPES plaque backing on the 3D dose distribution. …
Suitability Assessment Framework Of Agent-Based Software Architectures, Ghassan Beydoun, Graham Low, Paul Bogg
Suitability Assessment Framework Of Agent-Based Software Architectures, Ghassan Beydoun, Graham Low, Paul Bogg
Faculty of Engineering and Information Sciences - Papers: Part A
Context: A common distributed intelligent system architecture is Multi Agent Systems (MASs). Creating systems with this architecture has been recently supported by Agent Oriented Software Engineering (AOSE) methodologies. But two questions remain: how do we determine the suitability of a MAS implementation for a particular problem? And can this be determined without AOSE expertise? Objective: Given the relatively small number of software engineers that are AOSE experts, many problems that could be better solved with a MAS system are solved using more commonly known but not necessarily as suitable development approaches (e.g. object-oriented). The paper aims to empower software engineers, …

Modelling A Longwall Production System Using Flexsim 3d Simulation Software, D Cai, E Baafi, I Porter
Faculty of Engineering and Information Sciences - Papers: Part A
Longwall mining accounts for more than 75% of underground coal production in Australia. It is a popular underground coal mining method worldwide, mainly due to its high extraction ratio, high productivity and increased safety due to improved powered support units. A longwall system requires significant capital investment, and it is necessary to minimise the financial risk associated with this investment. Minimisation of this financial risk requires a sound knowledge of the relationship between underlying operational/technical constraints and associated costs. A discrete simulation model using the Flexsim 3D virtual reality environment has been developed to assist management evaluate the impact of …

Success And Abandonment In Open Source Commons: Selected Findings From An Empirical Study Of Sourceforge.Net Projects, Charles M. Schweik, Robert English, Qimti Paienjton, Sandy Haire
Charles M. Schweik
Some open source software collaborations are sustained over long periods of time and across several versions of a software product, while others become abandoned even before the first version of the product has been developed. In this study, we identify factors that might be responsible for one or the other of these collaborative trajectories. We examine 107,747 open source software projects hosted on Sourceforge.net in August 2006 using data available through the FLOSSmole Project. We employ Classification and Regression Tree modeling and Random Forests statistical approaches to begin to establish an understanding of how various project attributes, especially physical and …
An Agent-Oriented Approach To Support Change Propagation In Software Evolution, Hoa K. Dam
An Agent-Oriented Approach To Support Change Propagation In Software Evolution, Hoa K. Dam
Faculty of Engineering and Information Sciences - Papers: Part A
Software maintenance and evolution is arguably a lengthy and expensive phase in the life cycle of a software system. A critical issue at this phase is change propagation: given a set of primary changes that have been made to software, what additional secondary changes are needed? Although many approaches have been proposed, automated change propagation is still a significant technical challenge in software maintenance and evolution. This paper presents a Ph.D. research in the final stages of developing and evaluating a novel, agent-based, framework to support semi-automated change propagation in evolving software systems.

Ip's Problem Child: Shifting The Paradigms For Software Protection, Jacqueline D. Lipton
Articles
Computer software is somewhat of a problem child for intellectual property law. Courts and legislatures have struggled to encourage innovations in software development while, at the same time, attempting to avoid undesirable digital information monopolies. Neither the patent nor the copyright system has provided a particularly satisfactory paradigm for software protection. Although patents have received greater attention than copyrights in the software context (consider, for example, the recent BlackBerry case), copyright law arguably creates more insidious undercurrents in today's marketplace. This is partly because we have not yet appreciated the potential impact of recent developments in programming methodology and digital …

Faculty of Engineering and Information Sciences - Papers: Part A
Software maintenance and evolution are inevitable activities since almost all software that is useful and successful stimulates user-generated requests for change and improvements. One of the most critical problems in software maintenance and evolution is to maintain consistency between software artefacts by propagating changes correctly. Although many approaches have been proposed, automated change propagation is still a significant technical challenge in software engineering. In this paper we present a novel, agent-oriented approach to deal with change propagation in evolving software systems that are developed using the Prometheus methodology. A metamodel with a set of the Object Constraint Language (OCL) rules …

Smoothing With Mixed Model Software, Long Ngo, M P. Wand
Smoothing With Mixed Model Software, Long Ngo, M P. Wand
Faculty of Engineering and Information Sciences - Papers: Part A
Smoothing methods that use basis functions with penalization can be formulated as fits in a mixed model framework. One of the major benefits is that software for mixed model analysis can be used for smoothing. We illustrate this for several smoothing models such as additive and varying coefficient models for both S-PLUS and SAS software. Code for each of the illustrations is available on the Internet.
Www Sites Vs. Applications Software: The Dais Model, Lejla Vrazalic, Peter N. Hyland
Www Sites Vs. Applications Software: The Dais Model, Lejla Vrazalic, Peter N. Hyland
Faculty of Engineering and Information Sciences - Papers: Part A
Since the advent and widespread use of the Internet, it has become apparent that there are significant differences between applications software and WWW sites which warrant a re-examination of HCI design and evaluation methods. Previous research has identified and documented the factors which differentiate between applications software and WWW sites, however a well defined model of these differences and their origins was not available. This paper defines such a model of Distinguishing Attributes for Informational Sites (DAIS). © 2003 ACM.
Why Don't We Teach Software Engineers About The Law?, Anne Fuller, Peter Croll
Why Don't We Teach Software Engineers About The Law?, Anne Fuller, Peter Croll
Faculty of Engineering and Information Sciences - Papers: Part A
Much work has been done in recent years developing software engineering curricula. SE research has traditionally focused on the needs of very large corporations undertaking equally mammoth and complex development projects, consequently, current curricula tend to focus on this model. Yet by far the majority of software development is undertaken by Small to Medium Enterprises. The rise of the internet as a platform for commercial applications has partly driven this move away from monolithic software development. Depending on the nature of the application itself many of these products can be described as 'critical' with the failure of such a product …

Several studies have demonstrated the advantages of using interactive voice response (IVR) technology to collect self-report data from research participants and recipients of psychological/medical services. IVR allows participants to phone a computer and respond to recorded questions by pressing the appropriate touch-tone keys on their telephone. Because this technology offers substantial benefits in terms of cost and efficiency, it is surprising that it has not been more widely utilized by researchers and practitioners. Along with the automation of the administration and scoring of tests or surveys, IVR provides for questioning to be adapted to the participants' responses. One possible explanation …
