Capacitance-Voltage Studies Of Atomic-Layer-Deposited Mos Structrures On Gallium Arsenide And Other Iii-V Compound Semiconductors, Tian Yang

Department of Electrical and Computer Engineering Masters Theses

Si-based CMOS devices with traditional structure are approaching the fundamental physical limits. New device structures and materials must be explored to continue the trend of increasing electronic device speed and decreasing size at the same time. Recently, III-V compound semiconductors are considered as novel channel materials to replace Si due to their high electron mobilities. However, the main obstacle to implement III-V as novel channel materials for CMOS application is the lack of high-quality, thermodynamically stable insulators. Thus, systematic studies were carried out on atomic-layer-deposited (ALD) high-k dielectrics on GaAs and other III-V semiconductors. The experiment results show that interface …

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.

Increasing Security In The Physical Layer Of Wireless Communication, Luke Golygowski Dec 2007

Increasing Security In The Physical Layer Of Wireless Communication, Luke Golygowski

Australian Information Security Management Conference

This paper introduces a concept of increasing securing in the Physical layer (PHY) of wireless communication. It gives a short description of current status of wireless standards and their security. Despite the existence of advanced security protocols such as IEEE 802.11i or WLAN VPNs, wireless networks still remain vulnerable to denial-of-service (DoS) attacks aiming at PHY and Data Link Layers. The new solution challenges the problems with the currently defined PHY and Data Link layers. The concept introduced here, holds a promise of descending with some of the security measures to the lower layers of the TCP/IP and in this …

Securing Voip: A Framework To Mitigate Or Manage Risks, Peter James, Andrew Woodward

Australian Information Security Management Conference

In Australia, the past few years have seen Voice over IP (VoIP) move from a niche communications medium used by organisations with the appropriate infrastructure and capabilities to a technology that is available to any one with a good broadband connection. Driven by low cost and no cost phone calls, easy to use VoIP clients and increasingly reliable connections, VoIP is replacing the Public Switch Telephone Network (PSTN) in a growing number of households. VoIP adoption appears to be following a similar path to early Internet adoption, namely little awareness by users of the security implications. Lack of concern about …

How Safe Is Azeroth, Or, Are Mmorpgs A Security Risk?, An Hilven, Andrew Woodward

Australian Information Security Management Conference

Massive Multiplayer Online Role Playing Games (MMORPGs) are at a basic level a networked application. Blizzard’s World of Warcraft is currently the largest example of such a type of application, with over nine million subscribers at last count. Whilst the idea of researching a game for network security may sound trivial, nine million potential backdoors into home and business computers is not. The ports used by the game, as well as authentication methods and client update programs were examined using packet analysis software. No obvious vulnerabilities were discovered as a result of this analysis. In addition to this analysis, an …

It's Alive! The Gothic (Dis)Embodiment Of The Logic Of Networks, Anna Katharine Bennion Dec 2007

It's Alive! The Gothic (Dis)Embodiment Of The Logic Of Networks, Anna Katharine Bennion

Theses and Dissertations

My thesis draws connections between today's network society and the workings of gothic literature in the late eighteenth- and early nineteenth-century. Just as our society is formed and affected by the flow of information, the eighteenth-century culture of sensibility was formed by the merging and flow of scientific "technology" (or new scientific discoveries) and societal norms and rules. Gothic literature was born out of this science-society network, and in many ways embodies the ruptures implicit in it. Although gothic literature is not a network in the same sense as informationalism and the culture of sensibility are, gothic literature works according …

Niche Separation Along Environmental Gradients As A Mechanism To Promote The Coexistence Of Native And Invasive Species, Edmund R. Priddis Dec 2007

Niche Separation Along Environmental Gradients As A Mechanism To Promote The Coexistence Of Native And Invasive Species, Edmund R. Priddis

Theses and Dissertations

Niche separation may be the key to promoting the long-term coexistence of introduced and native species. Physical alterations to the environment (habitat manipulation) or re-introducing native species to former habitats can exploit the maladapted traits of introduced species to create a refuge for native species. No two species have identical niches because evolutionary constraints differ between species with different evolutionary histories. Our objectives were to determine if cold temperatures could promote coexistence between native least chub and introduced western mosquitofish. We used individual scale and population scale experiments to test four hypotheses: 1) colder temperatures would reduce the aggressive behavior …

Mathematically Modeling Pcr: An Asymptotic Approximation With Potential For Optimization, Martha J. Garlick Dec 2007

Mathematically Modeling Pcr: An Asymptotic Approximation With Potential For Optimization, Martha J. Garlick

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

A mathematical model for PCR (Polymerase Chain Reaction) is developed using the law of mass action. Differential equations are written from the chemical equations, preserving the detail of the complementary DNA single strand being extended one bas e pair at a time. The equations for the annealing stage are solved analytically. The method of multiple scales is used to approximate solutions for the extension stage. A map is then developed from the solutions to simulate PCR. The advantage of this model is the ability to use the map to optimize the process. Our results suggest that dynamically optimizing the extension …
