Detection Of Mine Roof Failure Using Inexpensive Lidar Technology, Ali Abdullah M. Alzahrani

Masters Theses

"Slope, Roof, and mine wall stability problems are some of the main reasons for deaths at U.S. surface or underground mining. The safety instruments were not enough to prevent that failure or even predict it before it occurs. However, the cost of such a tool that can be helpful in detecting roof failures is very high and not reachable in most instances.

The present study investigates the feasibility of using the M16 Leddar Evaluation Kit to detect the roof failure in mines. The M16 Leddar Evaluation kit cost is between 300$-800$, so it is the reachable price if it provides …

Multiple Security Domain Nondeducibility Air Traffic Surveillance Systems, Anusha Thudimilla

Masters Theses

"Traditional security models partition the security universe into two distinct and completely separate worlds: high and low level. However, this partition is absolute and complete. The partition of security domains into high and low is too simplistic for more complex cyber-physical systems (CPS). Absolute divisions are conceptually clean, but they do not reflect the real world. Security partitions often overlap, frequently provide for the high level to have complete access to the low level, and are more complex than an impervious wall. The traditional models that handle situations where the security domains are complex or the threat space is ill …

Sparse Emission Source Microscopy For Rapid Emission Source Imaging, Ling Zhang

Masters Theses

"In Paper I, Sparse Emission Source Microscopy (ESM) methodology will be introduced and discussed for the localization of major EMI radiation sources in complex and large systems. Traditional ESM method takes abundant and uniformly-distributed scanning points on the scanning plane using a robotic system, which can provide high-quality source images but consumes too much time. This section presents a sparse and nonuniform sampling technique for ESM, which is more time-efficient in identifying major radiation sources, even though the image quality is sacrificed. The feasibility of sparse sampling is mathematically proved, and it is shown that increasing number of points increases …

Uface: Your Universal Password No One Can See, Nicholas Steven Hilbert

Masters Theses

"With the advantage of not having to memorize long passwords, facial authentication has become a topic of interest among researchers. However, since many users store images containing their face on social networking sites, a new challenge emerges in preventing attackers from impersonating these users by using these online photos. Another problem with most current facial authentication protocols is that they require an unencrypted image of each registered user's face to compare against. Moreover, they might require the user's device to execute computationally expensive multiparty protocols which presents a problem for mobile devices with limited processing power. Finally, these authentication protocols …

Political Science & Geography Faculty Publications

(First paragraph) This paper aims to explain and analyze the role and the commitment of the United States in state-building, looking at three case studies coming from different regions and periods of time – from Germany to Iraq and Kosovo. The objective is to answer some critical questions such as how successful was the transition of state-building when it comes to security, economy, and institutions; what was the U.S. commitment; what happened for the better and for the worse; why in some countries was the state-building successful and in some countries not; and last but not least, how important is …

Stock Market Futurism, Merritt B. Fox, Gabriel Rauterberg

Faculty Scholarship

The U.S. stock market is undergoing extraordinary upheaval. The approval of the application of the Investors Exchange (IEX) to become the nation’s newest stock exchange, including its famous “speed bump,” was one of the SEC’s most controversial decisions in decades. Other exchanges have proposed a raft of new innovations in its wake. This evolving equity market is a critical piece of national infrastructure, but the regulatory scheme for its institutions is increasingly frayed. In particular, current regulation draws sharp distinctions among different kinds of markets for trading stocks, treating stock exchanges as self-regulatory organizations immune from private civil litigation, while …

Tissue regeneration is rapidly evolving to treat anomalies in the entire human body. The production of biodegradable, customizable scaffolds to achieve this clinical aim is dependent on the interdisciplinary collaboration among clinicians, bioengineers and materials scientists. While bone grafts and varying reconstructive procedures have been traditionally used for maxillofacial defects, the goal of this review is to provide insight on all materials involved in the progressing utilization of the tissue engineering approach to yield successful treatment outcomes for both hard and soft tissues. In vitro and in vivo studies that have demonstrated the restoration of bone and cartilage tissue with …

Trademarks And Unfair Competition, Clarisa Long

Faculty Scholarship

Chapter 9 summarizes the dominant law and economic approach to some of the doctrines comprising the two major strands of modern trademark law: classic trademark law, in which trademark protection is justified as reducing consumer search costs and preventing consumer confusion; and dilution law, which is explained by the more traditional intellectual property justifications of encouraging investment in creating valuable marks and protecting producer goodwill. It argues that the culmination of trademark law in the form of protection against dilution represents completion of a full circle of development of unfair competition law. From its start as a means of protecting …

Extraction Of The Nuetron Electric Form Factor From Measurements Of Inclusive Double Spin Asymmetries, V. Sulkosky, G. Jin, E. Long, Y.W. Zhang, M. Mihovilovic, A. Kelleher, B. Anderson, D. W. Higinbotham, S. Ŝirca, K. Allada, M. Canan

Physics Faculty Publications

Background: Measurements of the neutron charge form factor, Gⁿ_E , are challenging because the neutron has no net charge. In addition, measurements of the neutron form factors must use nuclear targets which require accurately accounting for nuclear effects. Extracting Gⁿ_E with different targets and techniques provides an important test of our handling of these effects.

Purpose: The goal of the measurement was to use an inclusive asymmetry measurement technique to extract the neutron charge form factor at a four-momentum transfer of 1(GeV/c)² . This technique has very different systematic uncertainties than traditional exclusive …

Expression Of Interleukin-1 And Temporomandibular Disorder: Contemporary Review Of The Literature, Adam Sorenson, Kyle Hresko, Seth Butcher, Sean Pierce, Vinícius Augusto Tramontina, Rosalia Leonardi, Carla Loreto, Jose A. Bosio, Luis Eduardo Almeida

School of Dentistry Faculty Research and Publications

Objective: Temporomandibular disorders (TMD) are a group of conditions affecting the temporomandibular joint (TMJ), leading to jaw dysfunction, joint and muscle pain, and a decrease in quality of life. A communication network of pro- and anti-inflammatory mediators called cytokines maintains the homeostasis of the TMJ. This review will focus on the Interleukin (IL) family of cytokines, which have been quantified in TMJ synovial fluids in a variety of studies. IL-1α and IL-1β have pro-inflammatory effects, while the endogenous receptor antagonist (IL-1RA) inhibits the pro-inflammatory effects of IL-1.

Methods: A literature search (2006–2016) to identify eligible studies was completed …

Tumor-Intrinsic Inflammatory Pathways Associated With Tumor Dormancy And Recurrence, Savannah E. Butler

Theses and Dissertations

The successful treatment of breast cancer is limited due to a fraction of tumor cells escaping drug-treatment by entering a dormant state, only to relapse years or decades later at distant sites. Host-driven chronic inflammatory cells such as M2 macrophages play an important role in tumorigenesis, but the role of tumor-intrinsic inflammatory signaling involved in tumor dormancy and recurrence is unknown. We sought to determine the role of tumor-intrinsic inflammatory pathways in mouse mammary carcinoma cells (MMC) treated with Adriamycin (ADR), a clinically relevant chemotherapeutic drug. We found that ADR-induced dormant tumor cells autonomously produced pro-inflammatory cytokines, in vitro. …

The Fractured Memory Of A Mind’S Eye, Russell G. White

Theses and Dissertations

The work I create is informed by questioning reality/identity, the fractalizing planes

of existence our essence occupies, and the artifacts of memory experience navigating

through space time. While existing in this realm of oversaturated media and neon

glow, I question the effects of pervasive data systems overloading or programming the

mental software we possess. My work includes humor as a means of exploring these

conventions while also displaying psychedelic surrealist imagery to help break away

from the conscious prison this existence births our concept apparatuses within.

Nanocomposite Bioelectronics For Biopotential Enabled Prosthesis, Dong Sup Lee

Theses and Dissertations

Soft material-enabled electronics can demonstrate extreme mechanical flexibility and stretchability. Such compliant, comfortable electronics allow continuous, long-term measurement of biopotentials on the skin. Manufacturing of the stretchable electronic devices is enabled by the recent development combining materials transfer printing and microfabrication. However, the existing method using inorganic materials and multi-layered polymers requires long material preparation time and expensive processing cost due to the requirement of microfabrication tools and complicated transfer printing steps. Here, this study develops a new fabrication method of soft electronics via a micro-replica-molding technique, which allows fast production, multiple use, and low cost by avoiding microfabrication and …

Negotiating Desire: Resisting, Reimagining And Reinscribing Normalized Sexuality And Gender In Fan Fiction, Charity A. Fowler

Theses and Dissertations

Fan studies has examined how fan fiction resists heteronormativity by challenging depictions of gender and sexuality, but to date, this inquiry has focused disproportionately on slash, to the exclusion of other genres of fan fiction. Additionally, scholars disagree about slash’s subversive effects by setting up a seemingly stable dichotomy—subversive vs. misogynistic—where one does not necessarily exist.

In this project, I examine multiple genres of fan fiction—namely, slash arising from bromances; femslash from female friendships; incestuous fan fiction from dysfunctional familial relationships; and polyamorous fics. I chose fics from four televisions shows—NBC’s Revolution, MTV’s Teen Wolf, the CW’s The …

Towards Design And Analysis For High-Performance And Reliable Ssds, Qianbin Xia

Theses and Dissertations

NAND Flash-based Solid State Disks have many attractive technical merits, such as low power consumption, light weight, shock resistance, sustainability of hotter operation regimes, and extraordinarily high performance for random read access, which makes SSDs immensely popular and be widely employed in different types of environments including portable devices, personal computers, large data centers, and distributed data systems.

However, current SSDs still suffer from several critical inherent limitations, such as the inability of in-place-update, asymmetric read and write performance, slow garbage collection processes, limited endurance, and degraded write performance with the adoption of MLC and TLC techniques. To alleviate these …

Health Aid In Africa: Placement, Service Utilization, And Benefit, Carrie Dolan

Theses and Dissertations

While the health sector has attracted significant foreign aid, evidence on the effectiveness of this support is mixed. This dissertation examines the allocation of health aid within the context of placement, service utilization, and benefit. The first paper examined the sub-national allocation of Chinese development aid projects across Africa. I determined how political preferencing of Chinese aid specifically, allocating aid to the birth region of the current political leader differs across sectors such as health, education, and transportation. I find some evidence that aid, more broadly defined, is subject to political preferencing in recipient countries, which could potentially limit its …

Investigation On Genetic Modifiers Of Age At Onset Of Major Depressive Disorder, Huseyin Gedik

Theses and Dissertations

Major Depressive Disorder (MDD) is a complex multifactorial disorder, which would lead to disability. Environmental and genetic factors are involved in MDD etiology. The aim of this project was to identify loci modifying age at onset (AAO) of MDD using survival models after adjusting for Childhood Sexual Abuse (CSA). To achieve this aim, a dataset was made available by the China Oxford and VCU Experimental Research on Genetic Epidemiology (CONVERGE) consortium. The study population had 5,220 controls and 5,282 cases with MDD. We performed two univariate association analyses using Cox Proportional Hazard (Cox PH) models. These two are Full Sample …

Depressive Symptoms Among College Students: An Exploration Of Fundamental Cause Theory, Peter A. Carrico

Theses and Dissertations

Fundamental Cause Theory suggests that socioeconomic and demographic factors are causal to various illnesses, including depression. However, no known previously existing research has used Fundamental Cause Theory to create a model of depression among college students. To do this, the present study conducted a stepwise binomial logistic regression to examine how socioeconomic status and the sociodemographic variables of Gender, Race, and Sexual Orientation, and others predict depressive symptoms in a large sample of undergraduates when controlling for stressful life events and social support (N = 2,915). Results support the hypothesis that socioeconomic disparities in depressive symptoms are the result …

Eye Movement Control: An Index For Athleticism, Brittany L. Oshea

Theses and Dissertations

Athletic potential is one of the most complex human traits. An elite athlete is produced from a complex interaction of an innumerable number of traits exhibited by the athlete. However, it’s not clear whether these traits are innate, allowing the athlete to excel, or, alternatively, are a consequence of practice. To be successful, athletes rely heavily on sensory information from the visual and vestibular systems. This study investigated the relationship eye movement control has with innate athleticism by comparing the saccadic and Vestibulo-Ocular Reflex (VOR) responses of former, no longer practicing, elite athletes against their age and gender matched counterparts …

Communication, Empathy, And Trust: Exploring Teachers' Partnerships With The Families Of Their Most Challenging Students, Kimberly W. Mcknight

Theses and Dissertations

The purpose of this embedded mixed methods collective case study was to explore eight kindergarten, first, and second grade teachers’ experiences partnering with families of their students who are at risk for emotional or behavioral disorders (EBDs). The teachers worked in two high-poverty, non-accredited Title-1 schools in an urban city. The study was part of a federally funded intervention called Behavioral, Emotional, and Social Training: Competent Learners Achieving School Success (BEST in CLASS- Elementary; BiC-E; Sutherland et al., 2017), which is targeted for students at risk for the development of EBDs. It uses evidence- based instructional practices to decrease students’ …

Global Command And Control For The Future Operating Concept: Implications For Structural Design And Information, Ian M. Slazinik, Benjamin T. Hazen

Faculty Publications

Due to increasing demands on air mobility aircraft, US Transportation Command(USTRANSCOM) has more recently advocated retaining operational control (OPCON)of aircraft it might have transferred to a requesting combatant command in the past. This recent approach mirrors that of similar-type civilian logistics operations that are centrally managed to maximize efficiencies by flowing resources to the point of need without having to navigate through time-consuming sourcing processes. Furthermore, the acceleration of information availability has condensed decision timelines and changed how similar civilian organizations organize and perform, allowing them to react seemingly on a dime to changing market conditions anywhere.4While retaining OPCON might …

Analyzing Social Impairments Under Title I Of The Americans With Disabilities Act, Susan Carle

Scholarly Articles in Law Reviews & Journals

This Article starts from the important contributions of the neurodiversity movement, which emphasizes the benefits of an expanded view of protecting human difference. These differences include variations in brain structure, behavior, and social functioning. Social impairments are a potential feature of many disabilities covered under the employment antidiscrimination provisions of Title I of the Americans with Disabilities Act ("ADA"), but the legal literature has not yet focused on the analytic issues social impairments present. This Article analyzes how the ADA's employment protections should apply in the social impairments context. Congress's enactment of the Americans with Disabilities Act Amendments ("ADAAA") in …

$=Euro=Bitcoin, Hilary Allen

Scholarly Articles in Law Reviews & Journals

Bitcoin (and other virtual currencies) have the potential to revolutionize the way that payments are processed, but only if they become ubiquitous. This Article argues that if virtual currencies are used at that scale, it would pose threats to the stability of the financial system-threats that have been largely unexplored to date. Such threats will arise because the ability of a virtual currency to function as money is very fragile-Bitcoin can remain money only for so long as people have confidence that bitcoins will be readily accepted by others as a means of payment. Unlike the U.S. dollar, which is …

Rage, Rage Against The Dying Of The Light: A Rhetorical Analysis Of The Role Of Existentialism, Grieving, And Space In Science Fiction Films, Daniel J. Roemer

EWU Masters Thesis Collection

This research explores a collection of science fiction films released in four consecutive years that are wholly unique among the genre, including Gravity (2013), Interstellar (2014), The Martian (2015), and Arrival (2016). These films advance themes first enacted in 2001: A Space Odyssey (1968) and Contact (1997). In fact, Ron Howard’s Apollo 13, while based on a real event, set the stage for many of the more frantic scenes of the four films under study. The films are examined using genre analysis in order to first illuminate common criteria that are found within the films, and then to explore why …
