A Model To Study Cyber Attack Mechanics And Denial-Of-Service Exploits Over The Internet's Router Infrastructure Using Colored Petri Nets, Lawrence M. Healy

Master's Theses and Doctoral Dissertations

The Internet‟s router infrastructure, a scale-free computer network, is vulnerable to targeted denial-of-service (DoS) attacks. Protecting this infrastructure‟s stability is a vital national interest because of the dependence of economic and national security transactions on the Internet. Current defensive countermeasures that rely on monitoring specific router traffic have been shown to be costly, inefficient, impractical, and reactive rather than anticipatory.

To address these issues, this research investigation considers a new paradigm that relies on the systemic changes that occur during a cyber attack, rather than individual router traffic anomalies. It has been hypothesized in the literature that systemic knowledge of …

Improved Implementation Of Kirkwood-Buff Solution Theory In Periodic Molecular Simulations, Joseph W. Nichols, Stan G. Moore, Dean R. Wheeler

Faculty Publications

Kirkwood-Buff (KB) solution theory is a means to obtain certain thermodynamic derivatives from knowledge of molecular distributions. In actual practice the required integrals over radial distribution functions suffer inaccuracies due to finite-distance truncation effects and their use in closed systems. In this work we discuss how best to minimize these inaccuracies under traditional KB theory. In addition we implement a method for calculating KB quantities in molecular simulations with periodic boundary conditions and particularly within the canonical ensemble. The method is based on a finite-Fourier-series expansion of molecular concentration fluctuations and leads to more reliable results for a given computational …

An Analysis Of Reading Instruction For Fifth Grade Students With Disabilities Served In Inclusive Elementary Classrooms, Elizabeth Dragone

Theses and Dissertations

This qualitative case study was designed to identify and analyze instructional strategies used by fifth grade teachers to meet the needs of students with disabilities receiving reading instruction in inclusive settings. Seven participants in a large suburban school system were chosen through purposeful, criterion-based sampling. Semi-structured interviews were used to gain information about how teachers use data related to student readiness, interests, and learning profiles to design differentiated instruction. Observations were used to gain information about how the teachers implemented differentiated content, process, and products in the classroom. As more students with disabilities are served in inclusive settings, teachers are …

Gan Heterojunction Fet Device Fabrication, Characterization And Modeling, Qian Fan

Theses and Dissertations

This dissertation is focused on the research efforts to develop the growth, processing, and modeling technologies for GaN-based Heterojunction Field Effect Transistors (HFETs). The interest in investigating GaN HFETs is motivated by the advantageous material properties of nitride semiconductor such as large band gap, large breakdown voltage, and high saturation velocity, which make it very promising for the high power and microwave applications. Although enormous progress has been made on GaN transistors in the past decades, the technologies for nitride transistors are still not mature, especially concerning the reliability and stability of the device. In order to improve the device …

Dinosaurian Faunas Of The Cedar Mountain Formation And La-Icp-Ms Detrital Zircon Ages For Three Stratigraphic Sections, Hirotsugu Mori

Theses and Dissertations

The Cedar Mountain Formation contains the most diverse record of Early Cretaceous dinosaurs in the western hemisphere. However, analyses of its faunas have been hindered because 1) most taxa are based on incomplete/fragmentary materials or incomplete descriptions, 2) most sites and some horizons preserve few taxa, and 3) the stratigraphy and geochronology are poorly understood. To help resolve these stratigraphic and correlation problems U-Pb LA-ICP-MS detrital zircon ages were obtained at significant sites and horizons. These dates indicate all sites at or near the base of the formation are no older than 122 to 124 Ma, thus all basal stratigraphic …

Variability In Construction Of Cement-Treated Base Layers: Probabilistic Analysis Of Pavement Life Using Mechanistic-Empirical Approach, Tyler J. Rogers

Theses and Dissertations

The primary objective of this research was to quantify the improvement in service life of a flexible pavement constructed using full-depth reclamation (FDR) in conjunction with cement stabilization when specified reductions in the spatial variability of specific construction-related parameters are achieved. This study analyzed pavement data obtained through field and laboratory testing of a reconstruction project in northern Utah. Data analyses included multivariate regression, Monte Carlo simulation, and mechanistic-empirical analyses of a model pavement structure. The results of the research show a steadily increasing trend in 28-day unconfined compressive strength of the cement-treated base (CTB) layer with increasing reductions in …

A Systematic Examination Of Data-Driven Decision-Making Within A School Division: The Relationships Among Principal Beliefs, School Characteristics, And Accreditation Status, Beth Teigen

Theses and Dissertations

This non-experimental, census survey included the elementary, middle, and high school principals at the comprehensive schools within a large, suburban school division in Virginia. The focus of this study was the factors that influence building administrators in using data to make instructional decisions. The purpose was to discover if there is a difference in the perceptions of elementary, middle, and high school principals of data use to make instructional decisions within their buildings. McLeod’s (2006) Statewide Data-Driven Readiness Study: Principal Survey was used to assess the principals’ beliefs about the data-driven readiness of their individual schools. Each principal indicated the …

The Things You Never Did Because You Might Die Trying., Kylene Thompson

Theses and Dissertations

Artist Statement My work is about the military. I represent my views of the military from my perspective as a military wife, sister, and daughter. The themes are about separation, endurance, and the fragility that lies beneath the people who serve, and the people that support them. It’s about pain, violence, anxiety, and fear, as well as pride and honor. I want my work to enhance the view of the military but also depict its hardships.

A Descriptive Study Of Teachers' Instructional Use Of Student Assessmetn Data, Nancy Hoover

Theses and Dissertations

The overarching question for this study is: to what extent are teachers using summative assessment data in a formative way? A survey research design study was implemented to address this question. A web-based survey was administered to elementary, middle, and high school teachers in a large, suburban school division in central Virginia. The survey data were used to determine the frequency with which teachers administered specific types of summative assessments, analyzed student summative assessment data, made changes in their instructional practice as a result of their analysis, and the level of teachers’ assessment literacy. The results of this study suggest …

Assessment Of Perceived Positive And Negative Outcomes In Risky Adolescent Dating And Peer Situations: A Descriptive Analysis Of Risk And Benefit Perception, Sarah Helms

Theses and Dissertations

Peer and dating violence perpetration and victimization are common experiences placing adolescents at-risk for maladaptive outcomes, yet little research has focused on specific problematic situations associated with these types of violence and other related risk-taking behaviors. Further, prevention programs have typically focused on changing beliefs, attitudes, and skill-deficits, with little attention to adolescents’ motivations or perceptions of costs and benefits associated with risky situations, despite support for this type of research in other health-related fields (e.g., substance abuse, behavioral medicine). The current study assessed adolescents’ perceptions of potential positive and negative outcomes associated with risky dating and peer situations, many …

Brief Of Constitutional Law Professors As Amici Curiae In Support Of Petitioners, Mcdonald V. City Of Chicago, No. 08-1521 (U.S. Nov. 23, 2009)., Richard L. Aynes, Jack M. Balkin, Randy E. Barnett, Steven G. Calabresi, Michael Kent Curtis, Michael A. Lawrence, William Van Alstyne, Adam Winkler

Con Law Center Amicus Briefs

The question in this case is whether the individual right to keep and bear arms recently recognized in District of Columbia v. Heller, and held applicable to the federal government, must also be protected against state infringement. The textually and historically accurate way to determine if the states must respect an individual right to keep and bear arms is to examine the meaning of the Privileges or Immunities Clause of the Fourteenth Amendment. Amici submit to the Court that the original meaning of the Privileges or Immunities Clause protected substantive, fundamental rights against state infringement, including the constitutional right of …

Automated Calibration Of The Gssha Watershed Model: A Look At Accuracy And Viability For Routine Hydrologic Modeling, Kayson M. Shurtz

Theses and Dissertations

The goal of hydrologic models is to accurately predict a future event of a given magnitude. Historic data are often used to calibrate models to increase their ability to forecast accurately. The GSSHA model is a distributed model that uses physical parameters and physics based computations to compute water flow from cell to cell based on a 2 dimensional grid. The goal of calibration is to obtain good estimates for the actual parameters of the watershed. These parameters should then transfer to other storm events of different magnitudes more easily than an empirical model. In conducting this research three watersheds …

R-Factor: A New Parameter To Enhance Location Accuracy In Rssi Based Real-Time Location Systems, Mohammed Rana Basheer, Sarangapani Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

The fundamental cause of localization error in an indoor environment is fading and spreading of the radio signals due to scattering, diffraction, and reflection. These effects are predominant in regions where there is no-line-of-sight (NLoS) between the transmitter and the receiver. Efficient algorithms are needed to identify the subset of receivers that provide better localization accuracy. © 2009 IEEE.

A Model Based Fault Detection And Accommodation Scheme For Nonlinear Discrete-Time Systems With Asymptotic Stability Guarantee, Balaje T. Thumati, Sarangapani Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a fault detection and accommodation (FDA) framework is developed for unknown nonlinear discrete-time systems. the changes in the system dynamics due to the faults are modeled as a nonlinear function of state and input variables while the time profile of the fault is assumed to be exponentially developing. a fault is detected by monitoring the system states and reconstructing the fault dynamics using online approximators. the online approximator output is used first for fault detection and later reconfigured for accommodation. a stable adaptation law in discrete time is developed not only to characterize the faults but also …
