Browsing Via Sonification, Taylor C. Cutlip

Graduate Theses, Dissertations, and Problem Reports (ETD)

Based on unexpected results in her previous research, Dr. Frances Van Scoy became inspired to develop a tool that allows the user to navigate spaces using auditory instead of visual cues to detect objects or anomalies in a given space in an effort to overcome the encountered obstacles. This problem report details the work of one of her grad students in exploring different open source software for developing the tool as well as research into gestures and other considerations when furthering this research into the third dimension at a future date.

Canonical Wnt Mechanisms In Neural Crest Induction, Mark Stephen Perfetto

Graduate Theses, Dissertations, and Problem Reports (ETD)

Canonical Wnt signaling is a pathway that is critical for normal development and the progression of disease. The canonical Wnt signaling pathway was put together carefully by synthesizing decades of research. Over those decades, canonical Wnt signaling was found to be crucial for nearly all aspects of development, but of importance to this thesis, is a key regulatory factor for the development of the highly migratory multipotent stem cells, the neural crest. As our knowledge of the importance of canonical Wnt signaling grew, research is being conducted to further our understanding of how canonical Wnt signaling communicates with other signaling …

Tie Strength, Optimal Connections, And Distance In Social Networks, David Anthony Buch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Social network analysis seeks to understand the structure of relationships in networks of actors. As researchers identify structural properties of interest (e.g. vulnerability to network cuts) they introduce measures to quantify the expression of those properties in observed networks. In fact, it is not uncommon that multiple measures are introduced purporting to evaluate a single property. Relative merits of competing measures are not self-evident but the corresponding inferences can conflict, encouraging arbitrary choice among measures and endangering the validity of conclusions. We argue (i) that multiplicity of measures is a necessary consequence of the de rigueur practice of conflating different …

Dynamic Discrepancy Reduced Order Modeling For Fischer-Tropsch Synthesis Over Cobalt-Based Catalyst, Jose Miguel Bohorquez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Advances in carbon capture techniques and demands in alternative fuel sources have increased over the past couple of decades. The Fischer-Tropsch Synthesis (FTS) provides a viable way to produce hydrocarbons from natural gas, coal, CO₂, or biomass. However, current comprehensive models for FTS encompass large number of reacting species, readsorption and conversion of primary products, surface intermediates, and coverage-dependent reaction rates. To accurately predict the products obtained through the process a reduced order model has been developed. By reducing the number of parameters of an existing comprehensive model, uncertainty is introduced. The uncertainty can be quantified by using …

An Empirical Analysis Of An Algorithm For The Budgeted Maximum Vertex Cover Problem In Trees, Mujidat Abisola Adeyemo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Covering problems are commonly studied in fields such as mathematics, computer science, and engineering. They are also applicable in the real world, e.g., given a city, can we build base-stations such that there is network availability everywhere in the city. However, in the real world, there are usually constraints such as cost and resources. The Budgeted Maximum Vertex Cover is a generalization of covering problems. It models situations with constraints. In this thesis, we empirically analyze an algorithm for the problem of finding the Budgeted Maximum Vertex Cover in undirected trees (BMVCT). The BMVCT problem is defined as follows: Given …

Examining Musical Hybridity And Cultural Influences In Valerie Coleman’S Wish Sonatine And Fanmi Imèn, Brittany Marie Trotter

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this research document is to examine elements of musical hybridity and cultural influences in renowned African-American flutist-composer Valerie Coleman’s Wish Sonatine and Fanmi Imèn for solo flute and piano. Prominently known for her chamber music works, Coleman describes her compositional style as “urban-classical,” which infuses elements of popular American styles into modern Western art music traditions to highlight and encapsulate the cultural experiences of various diasporas of our time.

The most significant elements of hybridity and cultural influences examined in Wish Sonatine and Fanmi Imèn are programmatic imagery and compositional motifs. The programmatic imagery is represented through …

Artificial Immune System For Unmanned Aerial Vehicle Abnormal Condition Detection And Identification, Ryan G. Mclaughlin

Graduate Theses, Dissertations, and Problem Reports (ETD)

A detection and identification scheme for abnormal conditions was developed for an unmanned aerial vehicle (UAV) based on the artificial immune system (AIS) paradigm. This technique involves establishing a body of data to represent normal conditions referred to as “self” and differentiating these conditions from abnormal conditions, referred to as “non-self”. Data collected from simulation of the UAV attempting to autonomously fly a pre-decided trajectory were used to develop and test a scheme that was able to detect and identify aircraft sensor and actuator faults. These faults included aerodynamic control surface locks and damages and angular rate sensor biases. The …

Music Technology, Gender, And Sexuality: Case Studies Of Women And Queer Electroacoustic Music Composers, Justin Thomas Massey

Graduate Theses, Dissertations, and Problem Reports (ETD)

This document aims to contribute to the established scholarship that highlights the role gender and sexuality has with one’s fundamental relationship to composition and music technology. The profession of electronic music composition and music production are strongly associated with notions of power and control, as much of this technology was built during the World Wars and Cold War. These aggressive views have created gendered language and metaphors in the field. Metaphors are the primary way in which we accommodate and assimilate information and experience to our conceptual organization of the world. It is at the source of our capacity to …

Population Health Of Spotted Salamanders (Ambystoma Maculatum) In Created Vernal Pools: An Integrative Approach, Alice R. Millikin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Habitat creation is an important tool for conservation to counteract habitat loss and degradation. Vernal pools are susceptible to destruction due to limited detection, protection, and regulation. These wetlands provide fishless breeding habitat for many amphibian species including spotted salamanders (Ambystoma maculatum) in eastern North America. Determining whether created vernal pool habitat is successful is often determined by demographic data of colonizing populations. I suggest that hormone levels, population genetics, and disease prevalence can improve our understanding of population health in created habitat. The goal of this dissertation was to assess the health of spotted salamander larvae in …

X-Ray Fluorescence Applications In Mudrock Characterization: Investigations Into Middle Devonian Stratigraphy, Appalachian Basin, Usa, Keithan Garrett Martin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mudrocks are characterized by nanometer-scale pore sizes and nano-darcy permeability, which plays a significant role in hydrocarbon flow during production. Resulting from these characteristics, mudrocks were exclusively considered a source rock, which charged overlying, more porous mediums. Hydraulic fracturing, a technology used to create artificial fractures to liberate hydrocarbons from the reservoir, enabled natural gas to be produced from mudrock reservoirs economically. Over the last fifteen years, this technology motivated research efforts to understand reservoir characteristics of mudrock. These investigations significantly improved our knowledge of mudrock systems, but have also highlighted key areas that are undeveloped and/or where conflicting hypotheses …

Behavioral Impairment Following Gestational Exposure To Titanium Dioxide Nanomaterial Aerosols In Male And Female Rats, Matthew Leland Eckard

Graduate Theses, Dissertations, and Problem Reports (ETD)

Engineered nanomaterials (ENMs) are beginning to be recognized as hazardous to human and animal health. Titanium dioxide (TiO2) is primarily used as a whitening agent in paints, plastics, and sunscreens. While relatively inert in its bulk form, nano-TiO2 (diameter) can produce prolonged inflammation and oxidative stress in target tissue. Recently, the potential for nano-TiO2 to cause neuroinflammation and damage has heightened concerns about its continued use. One important concern is that nano-TiO2, and other metal oxide ENMs, may affect fetal neurodevelopment. Accordingly, it is imperative to screen ENMs, like TiO2, for possible neurotoxicity following developmental exposures. The current set of …

Roadnet: Robust Adaptive Network For Information Diffusion In Vanet, Priyashraba Misra

Graduate Theses, Dissertations, and Problem Reports (ETD)

The automotive industry has changed more in the last one decade than ever before. Rapid advancements in autonomous driving have opened up opportunities for CAVs (Connected and Automated Vehicles). Vehicles today rely on a sensor-suite to map the surrounding and use that information for safety and navigation. The sensor's view is limited to its line of sight and this drawback can be tapered off by using Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I), generally referred to as Vehicle to Everything (V2X) communication. In this thesis, we specifically focus on utilizing V2V communication using on-board Dedicated Short Range Communication …

This qualitative study identified criteria for choosing specific folk-songs to include in formal recital, assessed quality in a folk-song arrangement, discussed suitable instrumentation for accompaniment, and suggested appropriate performance practices for concert performance. New folk-song literature was discovered through accessing original unpublished sources in the American Folklife Center of the Library of Congress. Finally, a format and program for incorporating the collected and composed folk-songs of Jean Ritchie in formal recital was …

Design And Implementation Of Overcurrent Protection Relays Test Bench, Khalid Daud Khattak

Graduate Theses, Dissertations, and Problem Reports (ETD)

The electrical power simulator in Engineering Sciences Building (ESB) at WVU was dismantled in July 2018. The simulator was used as a teaching tool for EE students to conduct lab experiments. The power simulator employed electromechanical and microprocessor protection relays, manual isolation and industrial circuit breakers, switches, variable autotransformer (VARIAC), voltmeters and ammeters. During the dismantling, a lot of equipment was retrieved for future possible use. This led to the idea of designing and implementing a simple circuit on a test bench that can be used as a lab equipment to demonstrate the operation of overcurrent protection relays. It was …

Internet Of Infringing Things: The Effect Of Computer Interface Copyrights On Technology Standards, Charles Duan

Scholarly Articles in Law Reviews & Journals

You connect to the Internet via your Wi-Fi access point. You surf the Web using a browser and send emails through your email server. You probably use some USB peripherals-say a mouse, keyboard, or printer. Maybe you even watch cable or broadcast television.

Under current case law, each of those computer systems and devices may very well be copyright-infringing contraband. This is through no fault of your own-you need not be pirating music or streaming illegal movies to infringe a copyright. The infringement simply exists, hard-wired within each of those devices and many more that you use, a result of …

Tests Of General Relativity With Gw170817, B. P. Abbott, R. Abbott, Teviet Creighton, Mario C. Diaz, Soma Mukherjee, Volker Quetschke, Malik Rakhmanov, K. E. Ramirez, Robert Stone, D. Tuyenbayev, W. H. Wang

Physics & Astronomy Faculty Publications

The recent discovery by Advanced LIGOand AdvancedVirgo of a gravitational wave signal from a binary neutron star inspiral has enabled tests of general relativity (GR) with this new type of source. This source, for the first time, permits tests of strong-field dynamics of compact binaries in the presence of matter. In this Letter, we place constraints on the dipole radiation and possible deviations from GR in the post-Newtonian coefficients that govern the inspiral regime. Bounds on modified dispersion of gravitational waves are obtained; in combination with information from the observed electromagnetic counterpart we can also constrain effects due to large …

Finding God In Community, S. Joseph Kidder, Jonny Wesley Moor

Faculty Publications

"God exists in community. Before the angels, before the universe, before perhaps time itself, the Father, Son, and Spirit shared a continuous love that can exist only in community.¹ Community is God’s primal manifestation of existence and reality. When God created humanity, He intended for us to be able to relate to Him, so the Lord made us male and female (Gen. 1:27), counterparts equal but distinct in community. Jürgen Moltmann argues that truly knowing something involves being able to participate with that entity.² For example, rather than learning physics merely to recite formulas and laws, …

Speech Across Borders, Jennifer Daskal

Scholarly Articles in Law Reviews & Journals

As both governments and tech companies seek to regulate speech online, these efforts raise critical, and contested, questions about how far those regulations can and should extend. Is it enough to take down or delink material in a geographically segmented way? Or can and should tech companies be ordered to takedown or delink unsavory content across their entire platforms—no matter who is posting the material or where the unwanted content is viewed? How do we deal with conflicting speech norms across borders? And how do we protect against the most censor-prone nation effectively setting global speech rules? These questions were …

Accommodating Competition: Harmonizing National Economic Commitments, Jonathan Baker

Scholarly Articles in Law Reviews & Journals

This article shows how the norm supporting governmental action to protect and foster competitive markets was harmonized with economic rights to contract and property during the 19th century, and with the development of the social safety net during the 20th century. It explains why the Constitution, as understood today, does not check the erosion of the entrenched but threatened national commitment to assuring competitive markets.

Who Owns The Rules Of War In Today's Post-Post-Cold War?, Kenneth Anderson

Scholarly Articles in Law Reviews & Journals

Professor Gabriella Blum's The Paradox of Power observes that international humanitarian law (IHL) has been in a long. term evolution toward putting the principle of "humanitarianism" and civilian protection at its normative and legal center. The Lecture (on which this essay is a commentary) identifies several reasons for this, in particular (within and across liberal democratic societies) social acceptance of IHL as law but also as socially internalized norms that give IHL broad moral legitimacy. Accepting The Paradox of Power's main propositions as cor rect, this Commentary extends its account in several ways. First, The Paradox of Power's combination of …

The Deconstructed Issue-Spotting Exam, Jamie Abrams

Scholarly Articles in Law Reviews & Journals

This article proposes a teaching technique for use in large, Socratic-style law school classes to embed exam preparation, formative assessment, and lawyering simulations in the course without overburdening the professor or students. This technique is sustainable, yet highly efficacious for students.

Law schools nationwide are implementing new reforms pushing law schools toward stronger assessment techniques and client-based simulations better preparing students for the practice of law. Many law schools have implemented these reforms around the margins or outside of the traditional doctrinal course. Law schools have generally added new classes with experiential learning components or with simulations integrated into the …

The Application Of Cloud Resources To Terrain Data Visualization, Gregory J. Larrick

EWU Masters Thesis Collection

In this thesis, the recent trends in cloud computing, via virtual machine hosted servers, are applied to the field of big data visualization. In particular, we investigate the visualization of terrain data acquired from several major open data sets with a graphics library for browser based rendering. Similar terrain data visualization solutions have not fully taken advantage of remote computational resources. In this thesis, we show that, by using a collection of Amazon EC-2 machines for fetching and decoding of terrain data, in conjunction with modern graphics libraries, three dimensional terrain information may be viewed and interacted with by many …
