Intrusion Detection In Wireless Networks: A Data Mining Approach, Shyam Varan Nath

Electronic Theses and Dissertations 2000 - 2009

The security of wireless networks has gained considerable importance due to the rapid proliferation of wireless communications. While computer network heuristics and rules are being used to control and monitor the security of Wireless Local Area Networks (WLANs), mining and learning behaviors of network users can provide a deeper level of security analysis. The objective and contribution of this thesis is three fold: exploring the security vulnerabilities of the IEEE 802.11 standard for wireless networks; extracting features or metrics, from a security point of view, for modeling network traffic in a WLAN; and proposing a data mining-based approach to intrusion …

Investigation Of The Influence Of Surface Roughness On Reflection Coefficients Measured By A Chirp Sonar Using A Laser Profiling Of The Seafloor, Nicolas. Hache

Electronic Theses and Dissertations 2000 - 2009

This research investigates the validity of an acoustic propagation model by comparing theoretical reflection coefficients, function of frequency, to FAU chirp sonar measurements (chirp sub-bottom profiler). An acoustic model has been implemented to estimate the spectrum of energy reflected from sandy sediments in the presence of surface scattering. The surface roughness being the dominant reverberation part, the volume scattering has been neglected in this model. A laser scanning system involving an image-processing algorithm has been designed to measure the seafloor bottom roughness using 1D Fourier transforms. In the case of anisotropic roughness, an estimation of the sand ripples dominant direction …

Using qualitative methodology, three exemplary, collegial, yet demographically diverse high school math departments in the state of Florida were involved in this multi-site case study. The researcher collected data from interviews, observations, and documents. Sixty-one math teachers including department chairs were individually interviewed. These interviews were transcribed and coded …

Study On Glucose Metabolism: Computer Simulation And Modeling, Meta. Leesirikul

Electronic Theses and Dissertations 2000 - 2009

Sorensen's model of glucose metabolism and regulation is reconstructed using SimulinkRTM. Most of the existing glucose metabolism models consist of several mass balance equations that interact with each others. Graphical format used by SimulinkRTM provides a visualized perspective of such relations so that it is easier to modify the model on ad hoc basis. Type-I and Type-II diabetes with relevant clinical details are simulated. Further, a control strategy is introduced in order to simulate the control of exogenous insulin pump. Simulated results are consistent with available clinical data. Living systems in general, exhibit both stochastical and deterministic characteristics. Activities such …

Towards Reading Line Profiles Of Bardeen-Petterson Accretion Disks, Eric P. Vandernoot

Electronic Theses and Dissertations 2000 - 2009

Images of highly idealized Bardeen-Petterson accretion disks around Kerr black holes and their generated energy spectra line profiles are created via computer simulations in this work. The line profiles are examined in the relation to the original disk parameters to demonstrate that Bardeen-Petterson disks can be the source of the spectra we observe, even of actual systems. The challenges in computer programming the simulations and methods to overcome the challenges are discussed in the paper. Also discussed are the future work, improvements and intentions for the simulations. Finally, the discussion turns to the usage of indicators in these line profiles …

The XYZ system is based on distributed hash table (DHT). A unique ID and a color assigned to each node and each file. The author uses clustering method to create the system backbone by connecting the cluster heads together and uses color …

Validating The Search, Experience, And Credence Product Classification Framework In A Model Of Patronage Intentions, Tulay. Girard

Electronic Theses and Dissertations 2000 - 2009

Although the Internet as a shopping medium provides convenience to easily access products, the U.S. e-commerce retail sales still make up a very small percentage of the U.S. total retail sales. To better understand what influences consumers' choices to shop for products or services on the Internet versus local retail stores, this study tests the influence of antecedent factors of consumer patronage intentions for Internet and local retail stores. The study draws the antecedent factors from the extant literature, which include product classes, the importance consumers place on retailer attributes, and consumer perceived risk in product classes. Because the Internet …

A New Framework: Post-Kyoto Energy And Environmental Security, Lakshman D. Guruswamy

Publications

In this article Professor Guruswamy advances an argument for new energy agreements that address the immense global environmental challenge presented by the increasing global energy demands of both the developed and developing world. Arguing that new energy accords are needed to meet this challenge, he identifies and describes the decidedly interdisciplinary knowledge base and analytics required to negotiate such international instruments. The construction of these knowledge bases call for scientific, engineering, technological, legal, social, economic and behavioral expertise. Professor Guruswamy identifies pragmatic steps--including a targeted research agenda--that will contribute to such an undertaking and begin the arduous process of addressing …

The Supreme Court, Rule 10b-5, And The Federalization Of Corporate Law, Mark J. Loewenstein

Publications

This Article examines Supreme Court jurisprudence since 1997 under the federal securities laws in light of the Court's earlier securities law decisions and in light of its recent decisions construing the Constitution and federal statutes as they relate to the regulation of business. These post-1977 cases strongly suggest that the much-heralded new federalism philosophy of the Supreme Court is not a factor in securities law cases or in business cases generally. Indeed, the opposite seems to be the case. In this context, new federalism cases appear to be an anomaly, with the reality being that the Court is still as …

Policing The Spectrum Commons, Philip J. Weiser, Dale N. Hatfield

Publications

One of the most contested questions in spectrum policy is whether bands of spectrum left as unlicensed will fall victim to the tragedy of the commons. Advocates of increased unlicensed spectrum often downplay what enforcement measures are necessary to minimize interference and to prevent the tragedy of the commons problem. Even imposing spectrum etiquette requirements in addition to the FCC's equipment certification program will fail to address this concern effectively, as the development of such measures - e.g., the requirement that devices listen before they talk - does not ensure that they will be followed. Indeed, if there are incentives …

Moody Investing And The Supreme Court: Rethinking The Materiality Of Information And The Reasonableness Of Investors, Peter H. Huang

Publications

This Article critically analyzes the judicial decisions and reasoning of the United States Supreme Court and lower courts accepting certain defenses in securities fraud litigation. This Article develops how and why the core notions of materiality of information and the reasonable investor should be revised in light of recent empirical data, experimental evidence, and theoretical models of moody investing. This Article proposes modifying three recent developments in materiality doctrine to take into account moody investing. In particular, this Article argues that current judicial treatment of puffery is flawed because it neglects the power of puffery to alter moods. This Article …

Isotopic Tracers As Evidence Of Denitrification In The Karlsruhe Aquifer, Eben J. Spencer

Theses and Dissertations

The Karlsruhe Aquifer of north-central North Dakota has experienced considerable nitrate contamination sparking an investigation by the North Dakota State Water Commission. Certain portions of the aquifer have experienced nitrate-N concentrations of up to seven times the drinking water standard. Although contamination is evident it is possible the NO₃¯ is naturally being eliminated by denitrification, whereby bacteria reduce NO₃¯ to nitrogen gas. Evidence of denitrification may be illustrated by accelerated reduction of NO₃¯ relative to the conservative tracer Cl¯ coupled with an increase in the heavy isotopes of 15N and 18O within the NO₃¯ ion. Such an increase is not …

A Template Functional-Gage Design Using Parameter-File Table In Autodesk Inventor, Cheng Lin, Moustafa Moustafa

Engineering Technology Faculty Publications

A systematic approach using Autodesk Inventor to design the functional gages of Geometric Dimensioning & Tolerancing (GD&T) is presented. The gages can be used to check straightness, angularity, perpendicularity, parallelism, and position tolerances of a part when geometric tolerances are specified with Maximum Material Condition (MMC). Four steps are proposed to accomplish the task: (1) creation of two-dimensional (2-D) initial template files, (2) generation of hierarchical folders for the template files, (3) creation a 3-D gage model from a specific template file, and (4) dimensioning and generation of the gage drawing. Results show that, by following this approach, students can …

Deep Drains To Manage Groundwater, Neil Cox, Sylvia Tetlow, Neil Coles

Bulletins 4000 -

A channel that is 1.0 m to 3.0 m in depth is considered to be a deep drain. The drain is excavated to a depth that is sufficient to intercept the watertable in order to capture and convey that groundwater from flat, poorly drained land.

The drain can either be ‘open’ to allow the inflow of surface water or ‘leeved’ to exclude surface water. An open deep drain has its spoil banks placed on one side or on alternate sides of the channel (Figure 1) while a leveed deep drain has continuous spoil banks placed on both sides of the …

Beyond The Roof, Faye. Pelosi

Electronic Theses and Dissertations 2000 - 2009

Ultimately, these verses are reflections of paintings (not necessarily paintings made with brush and oil, but paintings created by Nature, memory, and so forth). Each poem is also a painting and each painting is also a poem in the sense that the poetry should work the way a painting does by presenting a vivid image and idea. In every case, one has stemmed from the other. I want to translate the visual arts into writing, which includes the visual art of imagination because images are my natural language. These verses are an attempt at intermixing the categories (language and image), …

Valuing Diversity As An Imperative For Fulfilling The Mission Of The Church, Walter B. T. Douglas

Faculty Publications

Demographic shifts, cultural and ethnic diversity, globalization, and the rapid expansion of the church in the southern hemisphere strongly suggest that the future growth of Adventism may emerge in the developing nations. This article is an attempt to engage in conversation on the changing face of Adventism and the challenge this new Adventism presents across cultural, ethnic, and racially diverse communities. This article provides the church with a window of opportunity to view diversity not as an event but as a process to maximize and explore the richness of its diversity and to see it not as a problem to …

Nature/Culture Clash: The Transnational Trade In Gmos, Dayna Scott

All Papers

This paper aims to offer a fresh perspective into what is at stake in the cross-cultural trade dispute over genetically-modified organisms (GMOs) by subjecting a particular discursive sample, the parties’ submissions to the WTO panel, to critical scrutiny. The first step involves a survey of the rhetorical strategies deployed by the parties’ in the presentation of their arguments to the Panel. Next, I embark on the task of ‘disassembling the double helix’. My use of the term ‘double helix’ in this analysis refers to the close coupling of scientific and legal discourses in the trade regime: science and law are …

Blurring The Boundaries Between Immigration And Crime Control After Sept. 11th, Teresa A. Miller

Journal Articles

Although the escalating criminalization of immigration law has been examined at length, the social control dimension of this phenomenon has gone relatively understudied. This Article attempts to remedy this deficiency by tracing the relationship between criminal punishment and immigration law, demonstrating that the War on Terror has further blurred these distinctions and exposing the social control function that pervades immigration law enforcement after September 11th prioritized counterterrorism. In doing so, the author draws upon the work of Daniel Kanstroom, Michael Welch, Jonathan Simon and Malcolm Feeley.

The Pedagogical Significance Of The Bush Stem Cell Policy: A Window Into Bioethical Regulation In The United States (President George W. Bush, Fifth Anniversary Essay Collection), O. Carter Snead

Journal Articles

The enormous significance of the Bush stem cell funding policy has been evident since its inception. The announcement of the policy on August 9, 2001 marked the first time a U.S. president had ever taken up a matter of bioethical import as the sole subject of a major national policy address. Indeed, the August 9th speech was the President's first nationally televised policy address of any kind. Since then, the policy has been a constant focus of attention and discussion by political commentators, the print and broadcast media, advocacy organizations, scientists, elected officials, and candidates for all levels of office …
