Coordinated Persistent Homology And An Application To Seismology, Nickolas Brenten Callor
Coordinated Persistent Homology And An Application To Seismology, Nickolas Brenten Callor
Theses and Dissertations
The theory of persistent homology (PH), introduced by Edelsbrunner, Letscher, and Zomorodian in [1], provides a framework for extracting topological information from experimental data. This framework was then expanded by Carlsson and Zomorodian in [2] to allow for multiple parameters of analysis with the theory of multidimensional persistent homology (MPH). This particular generalization is considerably more difficult to compute and to apply than its predecessor. We introduce an intermediate theory, coordinated persistent homology (CPH), that allows for multiple parameters while still preserving the clarity and coherence of PH. In addition to introducing the basic theory, we provide a polynomial time …
Vertical Electrical Impedance Measurements Of Concrete Bridge Decks, Jared Scott Baxter
Vertical Electrical Impedance Measurements Of Concrete Bridge Decks, Jared Scott Baxter
Theses and Dissertations
This research focuses on the creation, validation, automation, and deployment of a nondestructive vertical electrical impedance (VEI) bridge deck assessment apparatus. A multichannel impedance analyzer with a moving platform is developed that can assess the deterioration state of a bridge deck without stationary traffic control. The multichannel apparatus is capable of taking over 500 impedance samples a second and can scan a bridge deck over 500 times faster than more traditional techniques. This research also shows VEI measurements are inversely proportional to the diffusivity of ions through concrete and that an impedance measurement frequency of 25 kHz is the most …

Methods And Application For Tracking Seedling Fate On The Utah Test And Training Range, Jesse Randal Morris
Theses and Dissertations
Remote sensing of the environment has become an effective and useful research approach applied across a wide range of scientific and professional disciplines. Generally remote sensing is used to evaluate patterns and processes at broad spatio-temporal scales, such as classifying landscape vegetation patterns or for creating digital surface models, however, there are increasing opportunities to expand the use of remotely sensed information to a wider range of applications at variable spatial and temporal scales. In the field of plant seedling and germination research methods are needed to improve plant establishment and restoration monitoring, particularly in areas that have historically low …
Scatterometer Cross Calibration Using Volume Scattering Models For Amazon Rainforest Canopies, Evan Neil Chrisney
Scatterometer Cross Calibration Using Volume Scattering Models For Amazon Rainforest Canopies, Evan Neil Chrisney
Theses and Dissertations
Spaceborne scatterometers have measured the normalized radar cross section (RCS) of the earth's surface for several decades. Two frequencies, C- and Ku-band, have been used in designing scatterometers, such as with the Ku-band NASA Scatterometer (NSCAT) and the C-band Advanced Scatterometer (ASCAT). The scatterometer data record between C- and Ku-band has been disjoint for several decades due to the difficulties in cross calibration of sensors that operate at different frequencies and incidence angles. A model for volume scattering over the Amazon rainforest canopy that includes both the incidence angle and frequency dependence is developed to overcome this challenge in cross …

American Black Bears (Ursus Americanus) Of The Paunsaugunt Plateau: Movements And Habitat Use, Rebekah Adriana Castro Dungan
Theses and Dissertations
Concerns over human-bear conflict and questions about the ecology of Paunsaugunt Plateau's population of black bears (Ursus americanus) arose due to their visitation to popular recreation sites. Greater insight about bears and their habitat use provides a foundation for conflict mitigation and effective management decisions. Between 2014 and 2017, seventeen black bears (11 female, 6 male) were fitted with global positioning system (GPS) radio-collars so that we could track their locations, daily activity patterns, and ambient temperatures. By analyzing bear locations, we calculated annual and seasonal home ranges for 16 bears, including 25 den sites. Home ranges typically consisted of …
Humans And The Red-Hot Stove: Hurston's Nature-Caution Theorizing In Their Eyes Were Watching God, Heather Sharlene Higgs Randall
Humans And The Red-Hot Stove: Hurston's Nature-Caution Theorizing In Their Eyes Were Watching God, Heather Sharlene Higgs Randall
Theses and Dissertations
This paper gives critical attention to the nature versus caution porch conversation in Zora Neale Hurston's Their Eyes Were Watching God, arguing that this is a legitimate addition to the anthropological discussion of nature versus culture. Addressing literary critics as well as scholars of the environmental humanities and of multispecies studies, I argue that Hurston's nature-caution discussion is a helpful epistemology which Hurston employs throughout her novel to suggest a single, unified way of understanding the human and nonhuman.

The importance of accent reduction to those who are learning English as a second language cannot be understated as it has direct and indirect impacts on credibility and income. This study is an evaluation of an instructional technique involving visual feedback through an electropalatography device to assist speakers in acquiring the /r/ and /l/ sound contrast in American English and whether or not that progress varied across speech task type or word position. This study involved four native Japanese participants in their first semester at the English Language Center located at Brigham Young University. Each subject participated in 7 45-minute …
China's Maritime Grand Strategy, Sarah Quan
China's Maritime Grand Strategy, Sarah Quan
Undergraduate Honors Theses
China’s goals in the South China Sea are twofold: to expand sovereignty while keeping the peace. I argue this is accomplished through rhetorical strategic ambiguity and military clarity, which have characterized China’s maritime grand strategy since 2010. Using confusion and clarity—two seemingly opposite strategies—allows China to simultaneously expand sovereignty and maintain peace. This paper first introduces the literature and theory behind grand strategy and strategic ambiguity. It then demonstrates how China’s intentions are made clear through military actions, then shows that China’s rhetoric is ambiguous to members of Association of Southeast Asian Nations (ASEAN) by weighing evidence that China is …

Skeletal muscle mass (SMM) in the lower body was measured via magnetic resonance imaging (MRI); additional exercise measurements included muscular strength and functional capacity. Quality of life was measured using Short Form 36 (SF-36). Nineteen females (age = 37.6 ± 9.8 yr, height = 164.4 ± 7.2 cm, mass = 106.9 ± 15.6 kg) were randomly assigned to 1 …
A Soft-Error Reliability Testing Platform For Fpga-Based Network Systems, Hayden Cole Rowberry
A Soft-Error Reliability Testing Platform For Fpga-Based Network Systems, Hayden Cole Rowberry
Theses and Dissertations
FPGAs are frequently used in network systems to provide the performance and flexibility that is required of modern computer networks while allowing network vendors to bring products to market quickly. Like all electronic devices, FPGAs are vulnerable to ionizing radiation which can cause applications operating on an FPGA to fail. These low-level failures can have a wide range of negative effects on the performance of a network system. As computer networks play a larger role in modern society, it becomes increasingly important that these soft errors are addressed in the design of network systems.This work presents a framework for testing …
The Role Of The Autonomic Nervous System In The Relationship Between Emotion Regulation And Conflict Tactics In Couples, Natalie Gold Orr
The Role Of The Autonomic Nervous System In The Relationship Between Emotion Regulation And Conflict Tactics In Couples, Natalie Gold Orr
Theses and Dissertations
Gross' emotion regulation model, Porges' polyvagal theory, and other existing research suggest that regulation of emotions, tactics used to handle conflict, and certain physiological processes that occur within the autonomic nervous system (ANS) in response to stress are significantly related, especially in relational contexts. However, despite their pervasiveness and negative impacts, there is a noticeable lack of research on predictors of violent, aggressive, or abusive conflict tactics in couples. In the current study, the predictive role of emotion regulation in relation to conflict tactics was examined, in addition to the role of respiratory sinus arrhythmia (RSA) and pre-ejection period (PEP) …

An Equivalence Of Shape And Deck Groups; Further Classification Of Sharkovskii Groups, Tyler Willes Hills
Theses and Dissertations
In part one we show that for a compact, metric, locally path-connected topological space X, the shape group of X - as defined in Foundations of Shape Theory by Mardesic and Segal - is isomorphic to the inverse limit of discrete homotopy groups introduced by Conrad Plaut and Valera Berestovskii. We begin by providing the reader preliminary definitions of the fundamental group of a topological space, inverse systems and inverse limits, the Shape Category, discrete homotopy groups, and culminate by providing an isomorphism of the shape and deck groups for peano continua. In part two we develop work and provide …
Is Binge Watching Bad For You? Escapism, Stress, Self-Controland Gratifications?, Weipu Wang
Is Binge Watching Bad For You? Escapism, Stress, Self-Controland Gratifications?, Weipu Wang
Theses and Dissertations
The relatively new phenomenon of binge watching presents a dramatic shift from the norm of traditional television viewing. However, is this ubiquitously popular media marathon that contains negative connotations really bad for you? A survey administered to 157 television binge-watchers identified the role of stress and self-control in influencing both the gratifications sought and the consequences of binge watching through the Structural Equation Modeling (SEM) analysis. The current study found that binge watching to avoid problems is a commonly employed strategy for individuals to cope with stress. However, engaging in binge-watching behavior as a coping mechanism to purposefully avoid problems …

Durability Of Hybrid Large Area Additive Tooling For Vacuum Infusion Of Composites, Nathan Joseph Northrup
Theses and Dissertations
The purpose of this research was to scientifically validate potential cost-saving measures for production of large area additively manufactured tooling for vacuum infusion of composites. These cost saving measures included using a hybrid additive/subtractive manufacturing system to fabricate the mold, requiring lower capital cost and creating shorter lead times. Fiberglass reinforcement was used instead of carbon in the mold material. The validation was done by designing and fabricating a mold for a custom test artifact and analyzing the surface geometry over the course of multiple infusions until tool failure.After printing and machining, the mold required a sealer in order to …
Materials Prediction Using High-Throughput And Machine Learning Techniques, Chandramouli Nyshadham
Materials Prediction Using High-Throughput And Machine Learning Techniques, Chandramouli Nyshadham
Theses and Dissertations
Predicting new materials through virtually screening a large number of hypothetical materials using supercomputers has enabled materials discovery at an accelerated pace. However, the innumerable number of possible hypothetical materials necessitates the development of faster computational methods for speedier screening of materials reducing the time of discovery. In this thesis, I aim to understand and apply two computational methods for materials prediction. The first method deals with a computational high-throughput study of superalloys. Superalloys are materials which exhibit high-temperature strength. A combinatorial high-throughput search across 2224 ternary alloy systems revealed 102 potential superalloys of which 37 are brand new, all …

Verb Usage In Egyptian Movies, Serials, And Blogs: A Case For Register Variation, Michael G. White
Verb Usage In Egyptian Movies, Serials, And Blogs: A Case For Register Variation, Michael G. White
Theses and Dissertations
This thesis contributes to the discussion of register variation within Egyptian Arabic by focusing on the usage of verbs in blogs and transcripts of movies and television. Register variation has been extensively researched for English as well as several other languages; yet, the lexical and grammatical features that distinguish registers of Egyptian Arabic have not been analyzed. Several challenges have prevented such an analysis, among them the perceived lack of an automatic annotator and the uncertainty of results. In order to overcome these challenges, two corpora were compiled: one containing texts from blogs and the other transcripts of movies and …
Exploring The Efficiency Of Software-Defined Radios In 3d Heat Mapping, Andrew Scott Thomas
Exploring The Efficiency Of Software-Defined Radios In 3d Heat Mapping, Andrew Scott Thomas
Theses and Dissertations
A common method of connecting to the internet is a wireless network. These networks can be monitored to discover the area of their coverage, but commercial receivers don't always provide the most accurate results. A software-defined radio was programmed to sniff wireless signals and tested against a commercial receiver and the results were compared. The results suggest that the software-defined radio performs at least as well as the commercial receiver in distance measurements and significantly better in samples taken per minute. It was determined that the software-defined radio is a viable replacement for a commercial receiver in 3D heat mapping.
The Ascension Of Jesus Christ: Its Role In Redemption From A Latter-Day Saint Theological Perspective, William Perez
The Ascension Of Jesus Christ: Its Role In Redemption From A Latter-Day Saint Theological Perspective, William Perez
Theses and Dissertations
Mosiah 18:2 lists the ascension of Jesus Christ as one of the atoning acts that brings about redemption. Although many faith traditions have developed a theology about the significance of the ascension, the topic has not been covered at length within The Church of Jesus Christ of Latter-day Saints. This thesis explores the ascension of Jesus Christ and its implications for humanity from the perspective of Latter-day Saint beliefs.The ascension of Jesus Christ can be considered the culmination, even the capstone of His atonement. There are sufficient sources within Latter-day Saint canon and the teachings of general authorities to support …
Depositional Analysis Of A Holocene Carbonate Strand Plain Using High Resolution Gpr, Sediment Analysis, And C-14 Dating, Kaleb Robert Markert
Depositional Analysis Of A Holocene Carbonate Strand Plain Using High Resolution Gpr, Sediment Analysis, And C-14 Dating, Kaleb Robert Markert
Theses and Dissertations
Understanding modern carbonate depositional systems gives valuable insights into the interpretation of ancient carbonate systems. Ancient carbonate strand plains have the potential to act as productive hydrocarbon reservoirs because of their relatively high porosity. Unfortunately, they are difficult to identify in the rock record because of the lack of work done on modern analogues. San Salvador Island in the Bahamas hosts a well-exposed and easily accessible Holocene strand plain, ideal as a modern analogue. Sandy Hook, located on the southeast part of the island, consists of approximately 35 ridge-swale features that show signs of four distinct zones of deposition. In …
Almost Homeomorphisms And Inscrutability, Michael Steven Andersen
Almost Homeomorphisms And Inscrutability, Michael Steven Andersen
Theses and Dissertations
“Homeomorphic'' is the standard equivalence relation in topology. To a topologist, spaces which are homeomorphic to each other aren't merely similar to each other, they are the same space. We study a class of functions which are homeomorphic at “most'' of the points of their domains and codomains, but which may fail to satisfy some of the properties required to be a homeomorphism at a “small'' portion of the points of these spaces. Such functions we call “almost homeomorphisms.'' One of the nice properties of almost homeomorphisms is the preservation of almost open sets, i.e. sets which are “close'' to …
Variance Reduction In Wind Farm Layout Optimization, Bertelsen Gagakuma
Variance Reduction In Wind Farm Layout Optimization, Bertelsen Gagakuma
Theses and Dissertations
As demand for wind power continues to grow, it is becoming increasingly important to minimize the risk, characterized by the variance, that is associated with long-term power forecasts. This thesis investigated variance reduction in power forecasts from wind farm layout optimization.The problem was formulated as a multi-objective optimization one of maximizing mean-plant-power and minimizing variance. The ε−constraint method was used to solve the bi-objectiveproblem in a two-step optimization framework where two sequential optimizations are performed. The first is maximizing mean wind farm power alone and the second, minimizing variance with a constraint on the mean power which is the value …

Electrical Conductivity Of The Aluminum Oxide Diffusion Barrier Following Catalytic Carbon Nanotube Growth, Berg Daniel Dodson
Electrical Conductivity Of The Aluminum Oxide Diffusion Barrier Following Catalytic Carbon Nanotube Growth, Berg Daniel Dodson
Theses and Dissertations
Carbon nanotube templated microfabrication (CNT-M) is a method that allows high-aspect ratio structures to be made for microelectromechanical systems (MEMS) devices. One concern when making monolithic electrical devices using CNT-M is that the aluminum oxide diffusion barrier will create too large of a resistance in the device. However, in developing CNT based MEMS devices, it has been observed that an electrical DC current is capable of transport from a conductive substrate, across the aluminum oxide, and through to the CNT structure grown on top of it. This thesis attempts to determine the mechanisms responsible for current being able to cross …

Testing A Scale Of Teacher Beliefs About Universal Curriculum Integration In The 21st Century (Uci21-T), Nicole E. Anderson
Theses and Dissertations
Curriculum integration is a unique approach to teaching. Twenty-first century skill approaches to curriculum integration train teachers in the process of curriculum integration, such that they are able to integrate various subject combinations in their teaching that produce new skills and dispositions in their students. Yet no scale to measure teachers' beliefs about the value of and efficacy beliefs towards implementing curriculum integration exists that is universal in the sense that it can be used any time any subject combination is integrated. Using a sample of 196 teachers at a professional development meeting in a mid-sized suburban school district in …

Outcomes For Professionals And Companies Through Student-Professional Reverse Mentoring Sessions, Nicholas Burr Gubler
Theses and Dissertations
This qualitative inquiry explores the outcomes that professionals, and their companies, experience when they participate in a student-professional reverse mentorship. Professional development is used across all trades and professions as a way to increase employee skills and improve product/service quality. Reverse mentoring, where a novice teaches the more experienced individual, is a relatively new approach in professional development. When the reverse mentoring scenario is between students and professionals, instead of professionals and their colleagues, we know that students benefit from the reverse mentoring process but little is known about what outcomes the professionals experience. This research reports that professionals experience …
