Medical Insecurity: When One Size Does Not Fit All, Patricia A. Williams Dec 2007

Medical Insecurity: When One Size Does Not Fit All, Patricia A. Williams

Australian Information Security Management Conference

Security is most commonly seen as a business concept. This is one reason for the poor uptake and implementation of standard security processes in non-business environments such as general medical practice. It is clear that protection of sensitive patient information is imperative yet the overarching conceptual business processes required to ensure this protection are not well suited to this context. The issue of sensitivity of information, together with the expectation that security can be effectively implemented by non-security trained professionals creates an insecure environment. The general security processes used by business, including those for risk assessment, are difficult to operationally …

A Single Channel Attack On 915mhz Radio Frequency Identification Systems, Christopher Bolan Dec 2007

A Single Channel Attack On 915mhz Radio Frequency Identification Systems, Christopher Bolan

Australian Information Security Management Conference

There has been some speculation as to the protection offered by the Frequency Hopping Spread Spectrum utilised by RFID technology. This paper explores the construction of an attack based on the broadcast of an attack signal in a single channel. The study details an experiment on two groups of tags where the experimental group are exposed to an attack signal broadcast on a single channel. With consistent findings across both control and experimental groups the experiment clearly demonstrates that FHSS offers no protection against such an attack.

Managing Analysis, David Shaw Dec 2007

Managing Analysis, David Shaw

Australian Information Warfare and Security Conference

The Intelligence profession requires effective management to function properly and professional discourse highlights the changing nature of intelligence work. Highlighted “failures” are linked to organizational structures and ethos, and proposals to address the problems include discussion of human and organizational factors with recommendations that address the issues. However, optimising the intelligence process may not be a simple case of applying management techniques as the work relies substantially on individual endeavour. Innovative management techniques are needed and these should be grounded in recognising the peculiar nature of analysis and the skill set required.

Effects Of Water Vapor On The Kinetics Of The Methylperoxy Radical Self-Reaction And Reaction With Hydroperoxy, Alecia Mower Dec 2007

Effects Of Water Vapor On The Kinetics Of The Methylperoxy Radical Self-Reaction And Reaction With Hydroperoxy, Alecia Mower

Theses and Dissertations

The gas phase reactions of CH3O2 + CH3O2, HO2 + HO2, and CH3O2 + HO2 in the presence of water vapor have been studied at temperatures between 263 and 303 K using laser flash photolysis coupled with UV time-resolved absorption detection at 220 nm and 260 nm. Water vapor concentration was quantified using tunable diode laser spectroscopy operating in the mid-IR. The HO2 self-reaction rate constant is significantly enhanced by water vapor, consistent with what others have reported, whereas CH3O2 self-reaction and the cross-reaction (CH3O2 + HO2) rate constants are nearly unaffected. The enhancement in the HO2 self-reaction rate coefficient …

). Size Dependency Of The Elastic Modulus Of Zno Nanowires: Surface Stress Effect, Guofeng Wang, Xiaodong Li

Faculty Publications

Relation between the elastic modulus and the diameter (D) of ZnOnanowires was elucidated using a model with the calculated ZnOsurface stresses as input. We predict for ZnOnanowires due to surface stress effect: (1) when D>20nm, the elastic modulus would be lower than the bulk modulus and decrease with the decreasing diameter, (2) when 20nm>D>2nm, the nanowires with a longer length and a wurtzite crystal structure could be mechanically unstable, and (3) when D<2nm, the elastic modulus would be higher than that of the bulk value and increase with a decrease in nanowire diameter.
