The DM framework is a synthesis of different technologies brought together for the purpose of enhancing the interrogation of these datasets. The DM framework is based on the data, information, knowledge and wisdom continuum as a horizontal axis, with DM and online analytical processing (OLAP) forming the vertical axis. In addition the DM framework incorporates aspects of data warehousing phases, …


The Use Of Alignment Cells In Mmcc Barcode, Siong Khai Ong, Douglas Chai, Alexander Rassau Jan 2010

The Use Of Alignment Cells In Mmcc Barcode, Siong Khai Ong, Douglas Chai, Alexander Rassau

Research outputs pre 2011

The QR code, a monochrome 2D barcode, is a popular and commonly used barcode system worldwide. QR codes can easily be read using a mobile phone with the appropriate decoder. As there is an increasing need for higher data capacity barcodes, some newer 2D barcodes, such as the MMCC code, have adopted the use of colour. However, the use of colour introduces more challenges for mobile phone decoders than with monochrome codes. In this paper, the use of alignment cells within the MMCC code is proposed to improve the robustness of the colour barcode when used in a mobile environment. …


Photovoltaic Micro-Cell Design For Distrubuted Power In Sensor Networks, Gary A. Allwood, Graham Wild, Steven Hinckley Jan 2010

Photovoltaic Micro-Cell Design For Distrubuted Power In Sensor Networks, Gary A. Allwood, Graham Wild, Steven Hinckley

Research outputs pre 2011

We present a new study of power over optical fiber, for use in optical fiber smart sensor networks, using silicon-based photovoltaic micro-cells. A number of parameters in the design of the micro-cell for implementation in a power converter chip have been investigated. Matching the beam profile to the active region, as well as maximizing the contact area improves the device efficiency. The effect of doping profile and junction type on the device performance, suggests silicon is a cost effective and suitable material for this application.


Digital Forensics And The Issues Of Identity, Andrew Jones, Thomas Martin Jan 2010

Digital Forensics And The Issues Of Identity, Andrew Jones, Thomas Martin

Research outputs pre 2011

The issue of what we consider to be the identity of a person has become increasingly complex as we have made ever greater use of the facilities and services that have been made available by developing technologies and the Internet. In the past people normally had one identity, while in the current environment it is acceptable to maintain separate ‘identities’ for different aspects of our on-line interactions. Proving beyond a reasonable doubt that an individual that is suspected of a crime that is based on the technologies that we increasingly rely on was the actual perpetrator has always been problematic. …

Predicting Memory Decline As A Risk Factor For Alzheimer's Disease In Older Post-Menopausal Women: Quod Erat Demonstrandum?, Mark Rodrigues, Jonathan Foster, Giuseppe Verdile, Karen Joesbury, Richard Prince, Amanda Devine, Pankaj Mehta, John Beilby, Ralph Martins

Research outputs pre 2011

Alzheimer's disease (AD) is the major form of age-related dementia worldwide, accounting for more than two-thirds of all dementia cases. The disease is characterized by a progressive loss of cognitive and intellectual functioning (Gilman, 1997). A number of risk factors for AD have been identified. The prevalence of AD increases with age, diabetes, depression, family history of Parkinson's disease and following head injury or exposure to solvents (Jorm et al., 1991; van Duijn et al., 1991; Ott et al., 1995; Yoshitake et al., 1995; Devanand et al., 1996). Published research further suggests that low education levels are associated with increased …


Absorption Enhancement Of Msm Photodetector Structure With A Plasmonic Double Grating Structure, Chee Leong Tan, Volodymyr V. Lysak, Narottam Das, Ayman Karar, Kamal Alameh, Yong Lee Jan 2010

Absorption Enhancement Of Msm Photodetector Structure With A Plasmonic Double Grating Structure, Chee Leong Tan, Volodymyr V. Lysak, Narottam Das, Ayman Karar, Kamal Alameh, Yong Lee

Research outputs pre 2011

We present finite difference time domain simulation to analyze the optical absorption enhancement of metal-semiconductor-metal photo detectors employing double plasmonic grating structures. Simulation results show that the combination of a subwavelength aperture and double nano-structured metal grating results in up to 25 times enhancement in optical absorption, in comparison to MSM photodetector structures employing only a subwavelength aperture. This improvement of the absorption enhancement is due to the coupling out function of the bottom grating structure which distributes the light to both side of the subwavelength aperture.


Analysis Of Hu's Moment Invariants On Image Scaling And Rotation, Zhihu Huang, Jinsong Leng Jan 2010

Analysis Of Hu's Moment Invariants On Image Scaling And Rotation, Zhihu Huang, Jinsong Leng

Research outputs pre 2011

Moment invariants have been widely applied to image pattern recognition in a variety of applications due to its invariant features on image translation, scaling and rotation. The moments are strictly invariant for the continuous function. However, in practical applications images are discrete. Consequently, the moment invariants may change over image geometric transformation. To address this research problem, an analysis with respect to the variation of moment invariants on image geometric transformation is presented, so as to analyze the effect of image's scaling and rotation. Finally, the guidance is also provided for minimizing the fluctuation of moment invariants.

Proximity To Rocky Reefs Alters The Balance Between Positive And Negative Effects On Seagrass Fauna, Fernando Tuya, Mathew Vanderklift, Glenn Hyndes, Thomas Wernberg, Mads Thomsen, Christine Hanson

Research outputs pre 2011

Proximity to habitat margins can alter the balance between positive and negative forces on species abundance. Based on this idea we examined abundance patterns of herbivorous gastropods in seagrasses adjacent to rocky reefs. We tested whether the balance between the intensity of predation (negative effect) and recruitment of new individuals (positive effect) changes with increasing distance from reefs. Abundances of gastropods varied with distance to reefs, but the direction of changes in abundance was taxon-specific: some taxa decreased in abundance with increasing distance from reefs (e.g. Pyrene bidentata), while others showed the opposite pattern (e.g. Cantharidus lepidus). Predators were more …

Call Admission Control Scheme For The Ieee 802.16e At Vehicular Speeds, Iftekhar Ahmad, Daryoush Habibi

Research outputs pre 2011

The IEEE 802.16e standard has emerged as an exciting mobile wireless broadband technology that promises to deliver both high throughput and guaranteed quality of service (QoS). Call admission control (CAC) scheme serves as a great utility for WiMAX, which ensures that resources are not over committed and thereby, all existing connections enjoy guaranteed quality of service. Existing CAC schemes largely depend on computation of available resources while making an acceptance or rejection decision once a new request arrives. Since wireless channels are not as reliable as wired communication, CAC scheme in WiMAX communication faces a serious challenge of making a …


A New Design For A Turing Test For Bots, Philip Hingston Jan 2010

A New Design For A Turing Test For Bots, Philip Hingston

Research outputs pre 2011

Interesting, human-like opponents add to the entertainment value of a video game, and creating such opponents is a difficult challenge for programmers. Can artificial intelligence and computational intelligence provide the means to convincingly simulate a human opponent? Or are simple programming tricks and deceptions more effective? To answer these questions, the author designed and organised a game bot programming competition, the BotPrize, in which competitors submit bots that try to pass a “Turing Test for Bots”. In this paper, we describe a new design for the competition, which will make it simpler to run, and, we hope, open up new …


Parties' Perceptions Of Apologies In Resolving Equal Opportunity Complaints, Alfred Allan, Dianne Mckillop, Robyn Carroll Jan 2010

Parties' Perceptions Of Apologies In Resolving Equal Opportunity Complaints, Alfred Allan, Dianne Mckillop, Robyn Carroll

Research outputs pre 2011

Apologies are known to play an important role in the resolution of discrimination and harassment complaints brought under equal opportunity legislation. Sometimes parties agree on an apology as a term on the basis of which a complaint is settled. Occasionally, where a complaint is not settled, a respondent will be ordered to apologize. The ability to order an apology is a distinctive feature of equal opportunity law in Australia. The aim of the researchers was to gather information on the role of apologies in the equal opportunity jurisdiction in Western Australia. Twenty-four complainants and respondents took part in semi-structured interviews. …

Turban Snails As Habitat For Foliose Algae: Contrasting Geographical Patterns In Species Richness, Thomas Wernberg, Fernando Tuya, Mads Thomsen, Gary Kendrick

Research outputs pre 2011

Understanding patterns of species richness is a major goal for ecologists, especially in space-limited habitats where many organisms live on top of others (epibiosis, e.g. by algae growing on gastropods in marine environments). We tested the hypotheses that species richness of epiflora on the gastropod Turbo torquatus would not differ between regions with similarly rich algal floras, and that epifloral richness would increase with increasing gastropod size. Macroalgal floras of Hamelin Bay (HB), Marmion (M), Jurien Bay (JB) and Kalbarri (K), Western Australia, ranged from ~20 to 40 species reef–1 (JB = HB = M ≥ K). Epiflora on small …

Research outputs pre 2011

As technology such as the Internet, computers and mobile devices become ubiquitous throughout society, the need to ensure our information remains secure is imperative. Unfortunately, it has long been understood that good security cannot be achieved through technical means alone and a solid understanding of the issues and how to protect yourself is required from users. Whilst many initiatives, programs and strategies have been proposed to improve the level of information security awareness, most have been directed at organizations, with a few national programs focused upon home users. Given people's use of technology is primarily focused upon those two areas: …

A Study Of Clinical Behaviour In Intensive Care Unit, Vivienne-Marie Smith Jan 2010

A Study Of Clinical Behaviour In Intensive Care Unit, Vivienne-Marie Smith

Research outputs pre 2011

In order to support the needs of the staff working in discrete areas of nursing, the attitudes, behaviors and needs of the group must first be articulated. Unfortunately, there has been little research conducted to understand the culture of what it is that health care workers think and feel and why they make the choices they do in their working environment and also why they chose to leave the environment. Specifically, what do intensive care clinicians think about the work they do when managing end-of-life care in this technical, highly skilled environment. The focus of an ethnographic study conducted in …


Bandwidth Allocation And Routing Information For Wireless Mobile Ad-Hoc Networks, Rajeshkumar Ramraj Jan 2010

Bandwidth Allocation And Routing Information For Wireless Mobile Ad-Hoc Networks, Rajeshkumar Ramraj

Research outputs pre 2011

An admission control Algorithm must organize among flows and should afford assurance of how the medium is shared between nodes. In a wired network, nodes can keep an eye on the medium to see how much bandwidth is being used by the network. On the other hand, in an Ad-Hoc network, during communication nodes possibly will use the bandwidth of neighbouring nodes. Consequently, the bandwidth consumption of flows and the accessible resources to a node are not local concepts, other than it being linked to the neighbouring nodes in carrier-sensing range. Current solutions do not address how to perform admission …


The Development Of A Video Task Of Remedial Behaviour To Use In Communication Training Of Health Professionals With Specific Reference To Open Disclosure Practice, Dianne Mckillop, Alfred Allan, Julian Dooley Jan 2010

The Development Of A Video Task Of Remedial Behaviour To Use In Communication Training Of Health Professionals With Specific Reference To Open Disclosure Practice, Dianne Mckillop, Alfred Allan, Julian Dooley

Research outputs pre 2011

The National Open Disclosure Standard requires health professionals (hereafter professionals) to disclose errors in the course of their practice. There is, however, evidence that some professionals are reluctant to do so because they are uncertain about how to engage in open disclosure communications in general and, specifically, how to do it in a legally appropriate manner. One way of addressing this problem is to train professionals in disclosing errors to patients and their families in ways that meet their psychological needs as well as the legal requirements. Although preferable, the comprehensive training of all professionals in appropriate open disclosure practices …


Design Of High-Sensitivity Plasmonics-Assisted Gaas Metal-Semiconductor-Metal Photodetectors, Ayman Karar, Narottam Das, Chee Leong Tan, Kamal Alameh, Yong Lee Jan 2010

Design Of High-Sensitivity Plasmonics-Assisted Gaas Metal-Semiconductor-Metal Photodetectors, Ayman Karar, Narottam Das, Chee Leong Tan, Kamal Alameh, Yong Lee

Research outputs pre 2011

In this paper, we use the finite difference timedomain (FDTD) method to optimize the light absorption of an ultrafast plasmonic GaAs metal-semiconductor-metal photodetector (MSM-PD) employing metal nano-gratings. The MSM-PD is optimized geometrically, leading to improved light absorption near the designed wavelength of GaAs through plasmon-assisted electric and magnetic field concentration through a subwavelength aperture. Simulation results show up to 10-times light absorption enhancement at 867 nm due to surface plasmon polaritons (SPPs) propagation through the metal nano-grating, in comparison to conventional MSM-PD.


A Wrapper-Based Feature Selection For Analysis Of Large Data Sets, Jinsong Leng, Craig Valli, Leisa Armstrong Jan 2010

A Wrapper-Based Feature Selection For Analysis Of Large Data Sets, Jinsong Leng, Craig Valli, Leisa Armstrong

Research outputs pre 2011

Knowledge discovery from large data sets using classic data mining techniques has been proved to be difficult due to large size in both dimension and samples. In real applications, data sets often consist of many noisy, redundant, and irrelevant features, resulting in degrading the classification accuracy and increasing the complexity exponentially. Due to the inherent nature, the analysis of the quality of data sets is difficult and very limited approaches about this issue can be found in the literature. This paper presents a novel method to investigate the quality and structure of data sets, i.e., how to analyze whether there …

Behaviour Profiling On Mobile Devices, Fudong Li, Nathan Clarke, Maria Papadaki, Paul Dowland

Research outputs pre 2011

Over the last decade, the mobile device has become a ubiquitous tool within everyday life. Unfortunately, whilst the popularity of mobile devices has increased, a corresponding increase can also be identified in the threats being targeted towards these devices. Security countermeasures such as AV and firewalls are being deployed, however, the increasing sophistication of the attacks requires additional measures to be taken. This paper proposes a novel behaviour-based profiling technique that is able to build upon the weaknesses of current systems by developing a comprehensive multilevel approach to profiling. In support of this model, a series of experiments have been …


Adult Outcomes Of Pediatric Traumatic Brain Injury, Miriam Beauchamp, Julian Dooley, Vicki Anderson Jan 2010

Adult Outcomes Of Pediatric Traumatic Brain Injury, Miriam Beauchamp, Julian Dooley, Vicki Anderson

Research outputs pre 2011

Traumatic brain injury (TBI) is one of the most common causes of acquired disability during childhood. While the majority of such injuries are mild, and result in few, if any, functional sequelae, children sustaining more significant insults may experience permanent cognitive and behavioral deficits. Clinical reports indicate residual impairments in a range of skills, particularly information-processing, attention, memory, learning, social function and behavior. These deficits impact on a child's capacity to interact with the environment effectively, resulting in lags in skill acquisition, and increasing gaps between injured children and their age peers, as they move through childhood and into adulthood. …

Bullying In School And Cyberspace: Associations With Depressive Symptoms In Swiss And Australian Adolescents, Sonja Perren, Julian Dooley, Therese Shaw, Donna Cross

Research outputs pre 2011

Background Cyber-bullying (i.e., bullying via electronic means) has emerged as a new form of bullying that presents unique challenges to those victimised. Recent studies have demonstrated that there is a significant conceptual and practical overlap between both types of bullying such that most young people who are cyber-bullied also tend to be bullied by more traditional methods. Despite the overlap between traditional and cyber forms of bullying, it remains unclear if being a victim of cyber-bullying has the same negative consequences as being a victim of traditional bullying. Method The current study investigated associations between cyber versus traditional bullying and …
