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 Comprehensive Firewall Testing Methodology, Murray Brand
A Comprehensive Firewall Testing Methodology, Murray Brand
Australian Information Security Management Conference
This paper proposes an all encompassing test methodology for firewalls. It extends the life cycle model to revisit the major phases of the life cycle after a firewall is in service as foundations for the tests. The focus of the tests is to show that the firewall is, or isn’t, still fit for purpose. It also focuses on the traceability between business requirements through to policy, rule sets, physical design, implementation, egress and ingress testing, monitoring and auditing. The guidelines are provided by a Test and Evaluation Master Plan (TEMP). The methodology is very much process driven and in keeping …
Increasing Security In The Physical Layer Of Wireless Communication, Luke Golygowski
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 …

The Importance Of Human Factors When Assessing Outsourcing Security Risks, Carl Colwill, Andy Jones
Australian Information Security Management Conference
The word is becoming increasingly interconnected and ways of doing business are evolving rapidly. Communications technology is ubiquitous and reliable and businesses are continuously seeking ways in which systems can be exploited to improve resilience, become more efficient and reduce costs. One way in which organisations seek to achieve this is by concentrating their efforts on core business processes and outsourcing non-core functions. However, outsourcing - and particularly offshoring - presents many security issues that must be considered throughout the lifetime of contracts. The scale of outsourcing and increasing technological and security complexity is making this task more difficult. Often …
The Need For An Investigation Into Possible Security Threats Associated With Sql Based Emr Software, Lee Heinke
The Need For An Investigation Into Possible Security Threats Associated With Sql Based Emr Software, Lee Heinke
Australian Information Security Management Conference
An increasing amount of E-health software packages are being bundled with Standard Query Language (SQL) databases as a means of storing Electronic Medical Records (EMR’s). These databases allow medical practitioners to store, change and maintain large volumes of patient information. The software that utilizes these databases pulls data directly from fields within the database based on standardized query statements. These query statements use the same methods as web-based applications to dynamically pull data from the database so it can be manipulated by the Graphical User Interface (GUI). This paper proposes a study for an investigation into the susceptibility of popular …
Securing Voip: A Framework To Mitigate Or Manage Risks, Peter James, Andrew Woodward
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 …

Averting Catastrophic Climate Change: Confronting Wealth, V Hurth, P Wells
Averting Catastrophic Climate Change: Confronting Wealth, V Hurth, P Wells
Plymouth Business School
In the context of potential catastrophic climate change, it is vital that fundamental drivers of carbon dioxide emissions are pinpointed and addressed. One of the key drivers of these emissions is shown to be increased economic wealth. This paper highlights that links between wealth and carbon dioxide must be addressed, and that although highly debated, the links are not well considered, especially at the detailed level of what drives consumption preferences of the global wealthy. In the context of increasing wealth concentration and poverty gaps, this subject is central to issues of social justice as well as environmental integrity. © …

Buffer Law And Transitional Roughness Effect In Turbulent Open-Channel Flows, Junke Guo, Pierre Y. Julien
Buffer Law And Transitional Roughness Effect In Turbulent Open-Channel Flows, Junke Guo, Pierre Y. Julien
Department of Civil and Environmental Engineering: Faculty Publications
A novel and complete velocity profile law is presented for turbulent open channel flows. The law embeds the linear law in the viscous sublayer; the quartic law due to turbulent bursting that must satisfy instantaneous mass conservation, the modified log-wake law in the outer region and the effects of wall roughness. Specifically, an arctangent law smoothly connects the linear law with the log law of the wall. Combining the arctangent law with the modified log-wake law, a continuous velocity profile is proposed for smooth boundary conditions. A complete velocity profile is obtained after subtracting a new roughness function. Finally, the …

A Costly Standoff: The Hart And Miller Islands Controversy, Raymond K. Shin
A Costly Standoff: The Hart And Miller Islands Controversy, Raymond K. Shin
Legal History Publications
In the 1970s, the state of Maryland planned to construct a diked disposal area on Hart and Miller Islands to contain contaminated spoil from dredging projects in the Chesapeake Bay. Environmental groups and nearby residents filed a lawsuit in opposition, relying on the Rivers and Harbors Act of 1899 along with other statutes and regulations. Although the courts held in favor of the defendants, the litigation caused years of delay and millions of dollars in added costs for the state. The Hart-Miller Island controversy demonstrates the importance of avoiding lawsuits against large-scale public works projects if at all possible, even …

Birck and NCN Publications
High-performance inversion-type enhancement-mode n-channel In0.65Ga0.35As metal-oxide-semiconductor field-effect transistors (MOSFETs) with atomic-layer-deposited Al2O3 as gate dielectric are demonstrated. A 0.5 mu m gate-length MOSFET with an Al2O3 gate oxide thickness of 10 nm shows a gate leakage current less than 5x10(-6) A/cm(2) at 4 V gate bias, a threshold voltage of 0.40 V, a maximum drain current of 670 mA/mm, and transconductance of 230 mS/mm at drain voltage of 2 V. More importantly, a model is proposed to ascribe this 80% improvement of device performance from In0.53Ga0.47As MOSFETs mainly to lowering the energy level difference between the charge neutrality level and …
