A Capabilities Analysis Of E-Fulfilment Businesses: Transformation In The Logistics Industry, Janice Burn, Paul Alexander Jan 2005

A Capabilities Analysis Of E-Fulfilment Businesses: Transformation In The Logistics Industry, Janice Burn, Paul Alexander

Research outputs pre 2011

This paper reports on the evaluation of practices of 48 leading e-fulfillment suppliers in the UK. Initial findings suggest that while a comprehensive model of e-fulfilment is validated these organisations are also providing services not previously recognised as e-fulfilment capabilities by the literature. This leads to the development of a staged model of transformation, which implies that the industry will embrace radical change in some sectors and lead to a new definition of e-fulfillment businesses. More in depth investigation leads to a proposed definition, and a methodology to measure the degree of transformation.

Optical Interference Suppression Using Microphotonic Rf Filter Structure, Rong Zheng, Kamal E. Alameh, Zhenglin Wang Jan 2005

Optical Interference Suppression Using Microphotonic Rf Filter Structure, Rong Zheng, Kamal E. Alameh, Zhenglin Wang

Research outputs pre 2011

The impact of laser coherence noise on conventional photonic RF filters is investigated in this paper. In addition, a new microphotonic adaptive RF filter structure is proposed, which can simultaneously suppress the phased-induced intensity noise caused by optical interference. Results show that the coherence length of the laser light significantly degrades the RF frequency response of a photonic transversal RF filter, whereas the microphotonic RF filter has the capability of generating arbitrary transfer function with no phase-induced intensity noise

Heuristics For Optimising The Calculation Of Hypervolume For Multi-Objective Optimisation Problems, Lyndon While, Lucas Bradstreet, Luigi Barone, Philip Hingston Jan 2005

Heuristics For Optimising The Calculation Of Hypervolume For Multi-Objective Optimisation Problems, Lyndon While, Lucas Bradstreet, Luigi Barone, Philip Hingston

Research outputs pre 2011

The fastest known algorithm for calculating the hypervolume of a set of solutions to a multi-objective optimization problem is the HSO algorithm (hypervolume by slicing objectives). However, the performance of HSO for a given front varies a lot depending on the order in which it processes the objectives in that front. We present and evaluate two alternative heuristics that each attempt to identify a good order for processing the objectives of a given front. We show that both heuristics make a substantial difference to the performance of HSO for randomly-generated and benchmark data in 5-9 objectives, and that they both …

A Critical Exploration Of The School Context For Young Adolescents Completing Primary Education, Sasha Stumpers, Lauren Breen, Julie Ann Pooley, Lynne Cohen, Lisbeth Pike Jan 2005

A Critical Exploration Of The School Context For Young Adolescents Completing Primary Education, Sasha Stumpers, Lauren Breen, Julie Ann Pooley, Lynne Cohen, Lisbeth Pike

Research outputs pre 2011

Many schools have adopted relational approaches to attend to the social context in which learning transpires. More recently however, such approaches and their supporters have been criticized for not examining the school context in its entirety and the student experience within this context. The current research sought to critically explore young adolescents' experiences within the context of their school. Fifteen year seven students in an Australian primary school were interviewed about their experiences of their school context. The data were analysed using a thematic analysis and a question-ordered matrix was constructed to aid the detection of themes and sub-themes from …

An Investigation Into The Efficiency Of Forensic Erasure Tools For Hard Disk Mechanisms, Craig Valli, Paul Patak

Research outputs pre 2011

One of the common anecdotal complaints used when defending the insecure erasure of hard disks is the length of time taken to affect a secure erasure. This paper discusses results of experiments conducted with Unix/Linux based hard disk wiping software when run on various machines and hard disk mechanisms in terms of size, speed and interface. The initial research has uncovered a range of issues and factors that affect the speed of erasure of hard disk mechanisms. Some of these factors included memory configuration and CPU but not in ways that were expected. This paper includes results from contemporary ATA …

Similarity-Aware Web Content Management And Document Pre-Fetching, Jitian Xiao, Michael Collins Jan 2005

Similarity-Aware Web Content Management And Document Pre-Fetching, Jitian Xiao, Michael Collins

Research outputs pre 2011

Web caching is intended to reduce network traffic, server load and user-perceived retrieval latency. Web pre-fetching, which can be considered as "active" caching, builds on regular Web caching, minimizing further a Web user's access delay. To be effective, however, the pre-fetching techniques must be able to predict subsequent Web access with minimum computational overheads. This paper presents a similarity-based mechanism to support similarity-aware Web document pre-fetching between proxy caches and browsing clients. We first define a set of measures to assess similarities between Web documents, and then propose a multi-cache architecture to cache Web documents based on those similarities. A …

Dynamic Wavelength Routing In All Optical Mesh Network, Kungmang Lo, Daryoush Habibi, Quoc Viet Phung, Hoang Nghia Nguyen Jan 2005

Dynamic Wavelength Routing In All Optical Mesh Network, Kungmang Lo, Daryoush Habibi, Quoc Viet Phung, Hoang Nghia Nguyen

Research outputs pre 2011

Wavelength-division multiplexing (WDM) offers the capability to handle the increasing demand of network traffic in a manner that takes advantage of already deployed optical fibers. Lightpaths are optical connections carried end-to-end over a wavelength on each intermediate link. Wavelengths are the main resource in WDM networks. Due to the inherent channel constraints, a dynamic control mechanism is required to efficiently utilize the resource to maximize lightpath connections. In this paper, we investigate a class of adaptive routing called dynamic wavelength routing (DWR), in which wavelength converters (WCs) are not utilized in the network. The objective is to maximize the wavelength …

A Uk And Australian Study Of Hard Disk Disposal, Craig Valli, Andrew Jones Jan 2005

A Uk And Australian Study Of Hard Disk Disposal, Craig Valli, Andrew Jones

Research outputs pre 2011

Recent studies in Australia and the United Kingdom indicate that a broad cross-section of organisations are failing to adequately protect or erase confidential data stored on hard disk drives before subsequent disposal. Over 90% of hard disks that were examined as a result of the two Independent studies were in an easily recoverable state with some drives simply requiring a boot. This paper will give an overview and comparison of the two studies conducted. Then an examination of possible factors responsible for the inadequate erasure of hard disk devices will be undertaken.

K Pair Of Disjoint Paths Algorithm For Protection In Wdm Optical Networks, Quoc Viet Phung, Daryoush Habibi, Hoang N. Nguyen, Kungmang Lo Jan 2005

K Pair Of Disjoint Paths Algorithm For Protection In Wdm Optical Networks, Quoc Viet Phung, Daryoush Habibi, Hoang N. Nguyen, Kungmang Lo

Research outputs pre 2011

Survivable routing in wavelength division multiplexing (WDM) optical networks has been proven to be NP-hard problem. There is a trade-off between the computational time and the optimality of solutions in existing approaches to the problem. Existing heuristic approaches purely based the graph algorithms are efficient in computational time but do not offer optimal solutions and may fail in some cases even when a solution exists. Meanwhile, the integer linear programming (ILP) models offer optimal solutions but are intractable even with moderate scale networks. In this paper, we introduce a new algorithm for finding K pairs of disjoint paths which are …

An Observational Study Of Bail Decision-Making, Alfred Allan, Maria Allan, Margaret Giles, Deirdre Drake, Irene Froyland Jan 2005

An Observational Study Of Bail Decision-Making, Alfred Allan, Maria Allan, Margaret Giles, Deirdre Drake, Irene Froyland

Research outputs pre 2011

Pre-trial detention of defendants has important legal, human rights and practical implications for defendants, their families, and society and therefore the area justifies research scrutiny. However, there is a dearth of empirical studies of bail decision-making and most of them have been retrospective studies. Prior studies have nevertheless identified a number of purported shortcomings in bail legislation and decision-making. The rarely used observational methodology employed in this study provided data that are not normally available from official records. The first appearances of 648 defendants were observed in the lower courts in metropolitan Perth (Western Australia) to identify factors that play …

A Bipartite Graph Approach To Generate Optimal Test Sequences For Protocol Conformance Testing Using The Wp-Method, Jun Wang, Jitian Xiao, Chiou Peng Lam, Huaizhong Li Jan 2005

A Bipartite Graph Approach To Generate Optimal Test Sequences For Protocol Conformance Testing Using The Wp-Method, Jun Wang, Jitian Xiao, Chiou Peng Lam, Huaizhong Li

Research outputs pre 2011

Conformance testing using test sequences is used to ensure that a protocol implementation conforms to its specification. A commonly used technique to generate test sequences for specifications described by the finite state machines is the Wp-method with the Reset technique, which frequently results in long test sequences. In this paper, we propose a bipartite graph approach to generate optimal test sequences for protocol conformance testing. Our approach significantly reduces the length of the test sequences required for conformance testing while maintaining the same fault detection capability.

Developing A Framework Of Training For The Older Small Business Owner : Final Report, Beth Walker, Beverley Webster, Julia Turner Jan 2005

Developing A Framework Of Training For The Older Small Business Owner : Final Report, Beth Walker, Beverley Webster, Julia Turner

Research outputs pre 2011

This study was conducted as a result of the critical issue of the ageing population and the implications this will have on the workforce. An employment option for older workers is to become self-employed and to start their own small businesses, rather than to continue working in mainstream employment, which becomes increasing difficult as employees age. The option of self-employment may be a viable option for older people as uncertainty of employment tenure in mainstream employment continues to increases over time and is a way to utilise work skills and competencies that have been acquired over years of work experience. …

A Randomised Control Trial To Reduce Bullying And Other Aggressive Behaviours In Secondary Schools, Donna Cross, Hall Marg, Stacey Waters, Greg Hamilton

Research outputs pre 2011

In Australia bullying tends to peak twice in a school student's life - firstly at age 1 0 to 12 and then during the two years following their transition to secondary school (Rigby, 1994; Slee, 1995b) This transition to secondary school is considered a critical period to intervene on bullying (Farrington, 1993; Rigby, 1997, 1999; Sharp, 1995; Stevens, Bourdeaudhuij, & Van Oost, 2000; Whitney & Smith, 1993). It is suggested that compared with primary schools, the change in friendship structures that accompanies the move to secondary school, large student numbers and the less consistent contact and fewer close relationships between …

A Shared Backup Path Protection Scheme For Optical Mesh Networks, Hoang N. Nguyen, Daryoush Habibi, Quoc Viet Phung, Kungmang Lo Jan 2005

A Shared Backup Path Protection Scheme For Optical Mesh Networks, Hoang N. Nguyen, Daryoush Habibi, Quoc Viet Phung, Kungmang Lo

Research outputs pre 2011

We propose a new heuristic ILP model for share backup path protection (SBPP) scheme of mesh networks, which used the sets of disjoint-joint primary-backup path candidates of using path-pair candidates. The solution of the model is near optimal and provides all the routing details of demands as well as the sharing information between backup paths, and also simplifies the wavelength assignment problem if the wavelength continuity is a consideration. The new entities are introduced into this model that allow to control the resource utilization as well as congestion level of the network for optimization purposes and the pre-processing of data …

Recommendations For Wireless Network Security Policy: An Analysis And Classification Of Current And Emerging Threats And Solutions For Different Organisations, Andrew Woodward

Research outputs pre 2011

Since their inception, 802.11 wireless networks have been plagued by a wide range of security problems. These problems relate to both data security and denial of service attacks, and there have been many solutions created by different vendors address these problems. However, the number of different types of attack, and the many possible solutions, makes it a difficult task to put in place an appropriate wireless network security policy. Such a policy must address both the size and nature of the enterprise, and the resources available to it. Measures such as WEP and MAC filtering are only appropriate for home …

Capacity Utilization Versus Congestion Levels In Wavelength Routing For Large Scale Wdm Networks, Quoc Viet Phung, Daryoush Habibi, Hoang N. Nguyen, Kungmang Lo Jan 2005

Capacity Utilization Versus Congestion Levels In Wavelength Routing For Large Scale Wdm Networks, Quoc Viet Phung, Daryoush Habibi, Hoang N. Nguyen, Kungmang Lo

Research outputs pre 2011

Wavelength routing (WR) has been a key issue in WDM optical networks which carry huge amount of traffic aggregated from Internet protocol (IP), asynchronous transfer mode (ATM) and SDH/SONET layers. The problem, however, has been proved NP-hard. The time complexity and the optimality of solutions are two conflicting metrics. In addition, for optimization purposes, capacity utilization and network congestion level can be compromised to reduce the blocking probability of future connections. In this paper, we propose a heuristic approach for WR in large scale networks based on a balanced model developed for the capacity utilization and the congestion level. This …

A Robust Qr Based Detector For V Blast And Its Efficient Hardware Implementation, Fariborz Sobhanmanesh, Saeid Nooshabadi, Daryoush Habibi

Research outputs pre 2011

The use of multiple antennas at both transmitting and receiving sides of a communication channel has increased the spectral efficiency to near the Shannon bound. However algorithmic complexity in the realization of the receiver is a major problem for its hardware implementation. In this paper we investigate a near optimal algorithm for V-BLAST detection in MIMO wireless communication systems based on QR factorization, offering remarkable reduction in the hardware complexity. Specifically, we analyze some hardware implementation aspects of the selected algorithm through MATLAB simulations and demonstrate its robustness. This technique can be used in an efficient fixed point VLSI implementation …

Ad2us: An Automated Approach To Generating Usage Scenarios From Uml Activity Diagrams, Robert Chandler, Chiou Peng Lam, Huaizhong Li

Research outputs pre 2011

Although attention has been given to the use of UML (Unified Modelling Language) activity diagrams in the generation of scenarios, thin-threads and test-cases, the processes described in the literature rely heavily on manual intervention either in the information extraction process or in the process of transforming them to an alternate structure. This paper introduces an approach that capture, store and output usage scenarios derived automatically from UML activity diagrams.

Physician Secure Thyself, Patricia Williams Jan 2005

Physician Secure Thyself, Patricia Williams

Research outputs pre 2011

Whilst discussion rages on the issues relating to security of medical data and the reason why it is important, there is little published information on how to tackle even basic security challenges for medical practice in Australia. Research suggests an underestimation of the threats to medical data by medical practitioners, hence there is sufficient reason to promote development of tools to assist medical practice with technical issues they are unfamiliar with. This paper provides an initial dialogue on how these security issues should be addressed. Included is a framework for risk assessment and elaboration of the implementation process to make …

Can Sense Of Community Inform Social Capital?, Julie Ann Pooley, Lynne Cohen, Lisbeth Pike Jan 2005

Can Sense Of Community Inform Social Capital?, Julie Ann Pooley, Lynne Cohen, Lisbeth Pike

Research outputs pre 2011

This paper examines the theoretical linkage between social capital and sense of community through research studies within four contextual areas. Social capital (SC) can be conceptualized as all the interactions between individuals in a community, and has been examined in various groups and communities. Sense of community (SoC) is a psychological construct that we argue is a correlate of social capital. Sense of community reflects the feelings of attachment and belonging that an individual has towards a community. Through qualitative and quantitative research carried out across the lifespan in four communities in Western Australia (i.e., Perth community, adolescent Jewish community, …

Security Governance: Its Impact On Security Culture, K. Koh, A. B. Ruighaver, S. B. Maynard, A. Ahmad Jan 2005

Security Governance: Its Impact On Security Culture, K. Koh, A. B. Ruighaver, S. B. Maynard, A. Ahmad

Research outputs pre 2011

While there is an overwhelming amount of literature that recognises the need for organisations to create a security culture in order to effectively manage security, little is known about how to create a good security culture or even what constitutes a good security culture. In this paper, we report on one of two case studies performed to examine how security governance influences security culture and in particular, the sense of responsibility and ownership of security. The results indicate that although the structural and functional mechanisms in security governance are influencing factors, it is the extent of social participation that may …
