Influence Of Substrate Stage Temperature And Rotation Rate On The Magneto-Optical Quality Of Rf-Sputtered Bi2.1dy0.9fe3.9ga1.1o12 Garnet Thin Films, Mohammad E. Alam, Mikhail Vasiliev, Kamal Alameh
Research outputs 2014 to 2021
Highly bismuth-substituted iron garnet thin films are prepared on quartz substrates by using a radio frequency (RF) magnetron sputtering technique. We study the factors (process parameters associated with the RF magnetron sputter deposition technique) affecting the magneto-optical (MO) properties of ferrite garnet films of composition Bi2.1Dy0.9Fe3.9Ga1.1O12. All films show high MO response across the visible range of wavelengths after being annealed. In particular, the effects of substrate stage temperature and rotation rate on the various properties of films are studied. Experimental results reveal that the characteristics of garnet films of this type can be tuned and optimized for use in …

Evaluating Single Sign On Security Failure In Cloud Services, Brian Cusack, Eghbal Zadeh
Australian Information Security Management Conference
The business use of cloud computing services is motivated by the ease of use and the potential financial cost reductions. Service failure may occur when the service provider does not protect information or when the use of the services becomes overly complex and difficult. The benefits also bring optimisation challenges for the information owners who must assess the service security risk and the degree to which new human behaviours are required. In this research we look at the risk of identity theft when ease of service access is provided through a Single Sign On (SSO) authorisation and ask: What are …

Intelligent Buildings: An Investigation Into Current And Emerging Security Vulnerabilities In Automated Building Systems Using An Applied Defeat Methodology, David J. Brooks
Australian Security and Intelligence Conference
Intelligent Buildings (IB) have become increasing popular during the past decade, driven through the need to reduce energy, have more reactive and safer buildings, and increase productivity. IB integrate many systems that were in the past isolated from each other, including fire and life safety, HVAC, lighting, security, etc. Facilities contain commercial-in-confidence material and other valued assets; however, IB are integrated through open and common data communication protocols and hardware, leaving facilities exposed to external and internal threats. The study presents an investigation into IB, based on a defeat evaluation methdology. IB vulnerabilities considered two areas, namely physical and software …
Security Risk Management In The Asia Pacific Region: What Are Security Professional Using?, David J. Brooks, Hamish Cotton
Security Risk Management In The Asia Pacific Region: What Are Security Professional Using?, David J. Brooks, Hamish Cotton
Australian Security and Intelligence Conference
The Asia Pacific (APAC) region encompasses a heterogeneous group of nation-states. Like the APAC region, the security industry operates within a diverse and multi-disciplined knowledge base, with risk management being a fundamental knowledge domain within security. Nevertheless, there has been limited understanding of what security professionals use when applying security risk management. The study was designed to gain a better understanding of risk management practice in place throughout APAC. Questions were generated to gauge an understanding of current practice and levels of implementation of standards and frameworks. Participants were drawn from many industries, using non-probabilistic sampling methods in a “snowball” …
A Strategy To Articulate The Facility Management Knowledge Categories Within The Built Environment, Robert Doleman, David J. Brooks
A Strategy To Articulate The Facility Management Knowledge Categories Within The Built Environment, Robert Doleman, David J. Brooks
Australian Security and Intelligence Conference
Security is applied in the built environment and this requires a close relationship with facility managers. Therefore, this study puts forward an approach to establish the facility management knowledge categories within the built environment. In part, the significance of the study stemmed from research undertaken into the compliance to Australian fire door maintenance within nursing homes, which demonstrated 87 percent noncompliance. This high level of non-compliance appeared to identify a lack of facility management knowledge, among other issues (Doleman & Brooks, 2011). The article uses a method to test the supposition of facility management knowledge construct in a three-phase Grounded …
Individualised Responses To Vigilance Demands And Their Management, Fiona M. Donald, Craig Hm Donald
Individualised Responses To Vigilance Demands And Their Management, Fiona M. Donald, Craig Hm Donald
Australian Security and Intelligence Conference
This research uses a task disengagement framework to examine how CCTV surveillance operators and novices respond to the vigilance demands of the detection process. Vigilance tasks are acknowledged as being high in mental workload, yet little is known about how operators deal with these demands in jobs where successful performance is reliant upon sustaining attention on a daily basis. Much vigilance research makes an implicit assumption that people perform tasks that require sustained attention in a passive manner. By contrast, this study examines how operators manage their levels of task engagement and attention resources. The sample consisted of 73 participants …
Defining The Security Professional: Definition Through A Body Of Knowledge, Mel Griffiths, David J. Brooks, Jeffrey Corkill
Defining The Security Professional: Definition Through A Body Of Knowledge, Mel Griffiths, David J. Brooks, Jeffrey Corkill
Australian Security and Intelligence Conference
A subject that eludes a consensus definition, security is an amalgam of disciplines that is moving inexorably towards professionalisation. Yet identifying who or what defines a security professional remains as difficult and elusory as a comprehensive definition of security that captures all of its modern facets and many actors. The view of elevating such a discipline as security to the status of a profession provokes polarised opinions. This article reviews the literature, examining what elements identify a security professional and exploring the significant themes and issues. To support these elements, security experts (n=27) were surveyed using a multidimensional scaling technique …

National Security: A Propositional Study To Develop Resilience Indicators As An Aid To Personnel Vetting, David Brooks, Jeff Corkill, Julie-Ann Pooley, Lynne Cohen, Cath Ferguson, Craig Harmes
Australian Security and Intelligence Conference
Within the National Security domain there is a convergence of security responsibility across the national security agencies, law enforcement and private security sectors. The sensitivity of this environment requires individuals operating in the domain to be honest, trustworthy and loyal. Personnel vetting is a formal process used to determine an individual’s suitability for access to this domain. Notwithstanding this process, significant breaches of trust, security, and corruption still occur. In psychology, resilience is a well researched phenomenon that is considered a multidimensional construct where individual attributes, family aspects and social environment interact in aiding individuals to deal with vulnerability. There …
“Make A Bomb In Your Mums Kitchen”: Cyber Recruiting And Socialisation Of ‘White Moors’ And Home Grown Jihadists, Robyn Torok
“Make A Bomb In Your Mums Kitchen”: Cyber Recruiting And Socialisation Of ‘White Moors’ And Home Grown Jihadists, Robyn Torok
Australian Counter Terrorism Conference
As a consequence of the war on terror, al-Qaeda and associated jihad groups have evolved and made increasing use of internet technologies for cyber recruitment. Recently, there has been an increasing focus on recruiting home grown terrorists who can more easily escape the scrutiny of cross border entries. Case study analysis indicates that links do exist between cyber tools, radicalisation and terrorism, however, the strength and nature of these relationships is generally unclear. Evidence does seem to support that cyber tools are most significant in the initial phases of recruitment and radicalisation. Coupled with this is the strong evolution of …

Triangulation Based Static Wide Angle Laser Scanning For Obstacle Detection, Kaveh Sahba, Kamal Alameh, Clifton Smith
Triangulation Based Static Wide Angle Laser Scanning For Obstacle Detection, Kaveh Sahba, Kamal Alameh, Clifton Smith
Research outputs pre 2011
This paper demonstrates discrete laser spot projection over a wide angle using a novel cylindrical quasi-cavity waveguide, with no moving parts. Furthermore, the distance to each spot is calculated using active laser triangulation. The triangulation arrangement and the trajectory of principal rays are modelled using a system of linear equations based on optical geometry. Linear algebra is used to derive the unique baseline and outgoing angle of every projected beam. The system is calibrated by finding optimal values for uncertain instrumental parameters using constrained non-linear optimization. Distances calculated indoors result in accuracies of over 93%

Digital Image Processing Using Mathematical Morphology, Andrew Mehnert
Digital Image Processing Using Mathematical Morphology, Andrew Mehnert
Theses : Honours
This dissertation is a natural extension of my undergraduate research project entitled, "Digital Image Processing”. Whilst my undergraduate project dealt with a number of classical digital image filtering techniques such as spatial convolution and frequency domain filtering via the Fourier transform, this dissertation focuses on an alternative approach employing Mathematical Morphology. In contrast to classical filtering techniques, which often geometrically distort the original image, morphological operations, used sensibly, essentially preserve shape and geometry. Mathematical morphology therefore lends itself to image processing applications requiring the identification of objects and object features within an image. Herein basic morphological operations are developed, firstly …
