Field Evaluation Of The Immunocontraceptive Gonacontm In Reducing Eastern Gray Squirrel Fecundity In Urban Areas, Murali Pai Dec 2009

Field Evaluation Of The Immunocontraceptive Gonacontm In Reducing Eastern Gray Squirrel Fecundity In Urban Areas, Murali Pai

All Dissertations

The purpose of this study was to evaluate the immunocontraceptive GonaConTM in reducing fecundity in Eastern gray squirrel (EGS) (Sciurus carolinensis) in urban areas. Using a modified box trap design, 317 EGS were captured during four trapping sessions on a 5.66 ha site on Clemson University's main campus. EGS were handled using a restraint cone and sexed, weighed, ear-tagged and implanted with a microchip at the nape of the neck on all 'original' captures and later identified in subsequent captures as 'recaptures.' Blood samples and morphometric data were obtained on EGS before the immunocontraceptive GonaConTM was administered by …

Synthesis, Modification Of Mesoporous Carbons And Their Application In Polymer Electrolyte Membrane Fuel Cells, Bing Liu

All Dissertations

Mesoporous carbon materials of carbon xerogel (CX) and silica-templated carbon (MC) were synthesized and explored as catalyst supports alternative to the most-commonly-used carbon black (CB) support, for polymer-electrolyte-membrane fuel cell (PEMFC) application. Pt catalyst was loaded on these carbons and electrodes were fabricated from them. These Pt-loaded carbon supports were characterized with XRD, TEM, ex-situ and in-situ cyclic voltammetry, etc. The fabricated electrodes were evaluated in single-cell testing in comparison with commercial CB-supported Pt catalyst fabricated electrodes. The experimental results showed that CX-supported Pt catalyst had close or better performance than that of CB-supported Pt, possibly due to CX's 3-D …

Examining The Dynamics Of Managing Information Systems Development Projects: A Control Loss Perspective, Ravi Narayanaswamy Dec 2009

Examining The Dynamics Of Managing Information Systems Development Projects: A Control Loss Perspective, Ravi Narayanaswamy

All Dissertations

The failure rate of information systems development (ISD) projects continues to pose a big challenge for organizations. The success rate of ISD projects is less then forty percent. Factors such as disagreements and miscommunications among project manager and team members, poor monitoring and intermediary problems contribute to project failure.
Agency theory and leader member exchange (LMX) theories offer potential explanations for project failure. In particular, three monitoring strategies - control strategy, decision rights, and influence tactics were found to be effective in promoting project success. LMX theorists suggest that achieving congruence between the manager and subordinate regarding each other actions …

Marine & Environmental Sciences Faculty Articles

Marine protected areas (MPAs) provide place-based management of marine ecosystems through various degrees and types of protective actions. Habitats such as coral reefs are especially susceptible to degradation resulting from climate change, as evidenced by mass bleaching events over the past two decades. Marine ecosystems are being altered by direct effects of climate change including ocean warming, ocean acidification, rising sea level, changing circulation patterns, increasing severity of storms, and changing freshwater influxes. As impacts of climate change strengthen they may exacerbate effects of existing stressors and require new or modified management approaches; MPA networks are generally accepted as an …

Security Requirements Engineering-The Reluctant Oxymoron, Michael N. Johnstone Dec 2009

Security Requirements Engineering-The Reluctant Oxymoron, Michael N. Johnstone

Australian Information Security Management Conference

Security is a focus in many systems that are developed today, yet this aspect of systems development is often relegated when the shipping date for a software product looms. This leads to problems post-implementation in terms of patches required to fix security defects or vulnerabilities. A simplistic answer is that if the code was correct in the first instance, then vulnerabilities would not exist. The reality of a complex software artefact is however, driven by other concerns. Rather than probing programs for coding errors that lead to vulnerabilities, it is perhaps more beneficial to look at the root causes of …

When You Can't See The Forest For The Domains: Why A Two Forest Model Should Be Used To Achieve Logical Segregation Between Scada And Corporate Networks, Andrew Woodward, Brett Turner Dec 2009

When You Can't See The Forest For The Domains: Why A Two Forest Model Should Be Used To Achieve Logical Segregation Between Scada And Corporate Networks, Andrew Woodward, Brett Turner

Australian Information Warfare and Security Conference

The increasing convergence of corporate and control systems networks creates new challenges for the security of critical infrastructure. There is no argument that whilst this connection of what was traditionally an isolated network, to a usually internet enabled corporate network, is unavoidable, segregation must be maintained. One such challenge presented is how to properly and appropriately configure an active directory environment to allow for exchange of required data, but still maintain the security goal of separation of the two networks. This paper argues that while separate domains may seem to achieve this goal, the reality is that a domain is …

Tactical Analysis Of Attack In Physical And Digital Security Incidents:Towards A Model Of Asymmetry, Atif Ahmad Dec 2009

Tactical Analysis Of Attack In Physical And Digital Security Incidents:Towards A Model Of Asymmetry, Atif Ahmad

Australian Information Warfare and Security Conference

Asymmetric warfare is frequently described as a conflict where ‘weaker’ parties aim to offset their relatively inadequate resources by using particular strategies and tactics to their advantage. This research-in-progress paper develops a concept model of asymmetric warfare that represents the leverage available to the ‘weaker’ party over the ‘stronger’ party simply because the former is attacking rather than defending. Points of leverage include choice of timing, location, method of attack, best use of limited resources and time to prepare. The resulting concept model is used to discuss generic defensive strategies that can be applied by ‘stronger’ parties in the physical …

Ascent Of Asymmetric Risk In Information Security: An Initial Evaluation., Tobias Ruighaver, Matthew Warren, Atif Ahmad Dec 2009

Ascent Of Asymmetric Risk In Information Security: An Initial Evaluation., Tobias Ruighaver, Matthew Warren, Atif Ahmad

Australian Information Warfare and Security Conference

Dramatic changes in the information security risk landscape over several decades have not yet been matched by similar changes in organizational information security, which is still mainly based on a mindset that security is achieved through extensive preventive controls. As a result, maintenance cost of information security is increasing rapidly, but this increased expenditure has not really made an attack more difficult. The opposite seems to be true, information security attacks have become easier to perpetrate and appear more like information warfare tactics. At the same time, the damage caused by a successful attack has increased significantly and may sometimes …

Explicit And Exact Solutions With Multiple Arbitrary Analytic Functions Of Jimbo–Miwa Equation, Sheng Zhang, Ying-Na Sun, Jin-Mei Ba, Ling Dong Dec 2009

Explicit And Exact Solutions With Multiple Arbitrary Analytic Functions Of Jimbo–Miwa Equation, Sheng Zhang, Ying-Na Sun, Jin-Mei Ba, Ling Dong

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, a generalized F-expansion method is used to construct exact solutions of the (3+1)-dimensional Jimbo–Miwa equation. As a result, many new and more general exact solutions are obtained including single and combined non-degenerate Jacobi elliptic function solutions, hyperbolic function solutions and trigonometric function solutions, each of which contains six arbitrary analytic functions. It is shown that with the aid of symbolic computation the generalized F-expansion method may provide a straightforward and effective mathematical tool for solving nonlinear partial differential equations.

Assessment Of Internationalised Domain Name Homograph Attack Mitigation, Peter Hannay, Christopher Bolan Dec 2009

Assessment Of Internationalised Domain Name Homograph Attack Mitigation, Peter Hannay, Christopher Bolan

Australian Information Security Management Conference

With the advent of internationalised domains the threat posed by non-english character sets has eventuated. Whilst this phenomenon remains well known in the development and internet industry the actual implementations of popular applications have been tested to determine their resilience to homograph based attack. The research found that most provided features that overcome such attacks, but there remain a few notable exceptions. Should an attacker take advantage of such oversights a victim would likely not be able to spot a fraudulent site or email and thus provide a perfect platform for subsequent attack.

Some Contributions In Statistical Discrimination Of Different Pathogens Using Observations Through Ftir, Dongmei Wang Dec 2009

Some Contributions In Statistical Discrimination Of Different Pathogens Using Observations Through Ftir, Dongmei Wang

Mathematics Theses

Fourier Transform Infrared (FTIR) has been use to discriminate different pathogens by signals from cells infected with these versus normal cells as references. To do the statistical analysis, Partial Least Square Regression (PLSR) was utilized to distinguish any two kinds of virus‐infected cells and normal cells. Validation using Bootstrap method and Cross‐validations were employed to calculate the shrinkages of Area Under the ROC Curve (AUC) and specificities corresponding to 80%, 90%, and 95% sensitivities. The result shows that our procedure can significantly discriminate these pathogens when we compare infected cells with the normal cells. On the height of this success, …

Theoretical And Numerical Study Of Tikhonov's Regularization And Morozov's Discrepancy Principle, Marygeorge L. Whitney Dec 2009

Theoretical And Numerical Study Of Tikhonov's Regularization And Morozov's Discrepancy Principle, Marygeorge L. Whitney

Mathematics Theses

A concept of a well-posed problem was initially introduced by J. Hadamard in 1923, who expressed the idea that every mathematical model should have a unique solution, stable with respect to noise in the input data. If at least one of those properties is violated, the problem is ill-posed (and unstable). There are numerous examples of ill- posed problems in computational mathematics and applications. Classical numerical algorithms, when used for an ill-posed model, turn out to be divergent. Hence one has to develop special regularization techniques, which take advantage of an a priori information (normally available), in order to solve …

Four-Body Model For Transfer Excitation, Allison L. Harris, Jerry Peacher, Don H. Madison, James Colgan

Physics Faculty Research & Creative Works

We present here a four-body model for transfer-excitation collisions, which we call the four-body transfer-excitation (4BTE) model. Each two-body interaction is explicitly included in the 4BTE model, allowing us to study the effects of individual two-body interactions. We apply our model to fully differential cross sections for proton+helium collisions, and study the effect of the incident projectile-atom interaction, the scattered projectile-ion interaction, the projectile-nuclear interaction, and electron correlation within the target atom.

Physics Faculty Research & Creative Works

We report on an experimental and theoretical systematic study of double ionization of helium by ion impact in terms of four-particle Dalitz plots. Several collision systems covering abroad range of perturbation parameters η (projectile charge to speed ratio) were investigated. With increasing η we observe a systematic trend from features, characteristic to correlated double-ionization mechanisms, to signatures of higher-order processes not requiring electron-electron correlations [the mechanism called "two-step-two projectile-electron interaction" (TS-2)]. The data for the largest η can qualitatively be amazingly well described by a simple model only including the TS-2 mechanism.
