Perfusion Pressure-Flow Relationships In Synthetic Poroelastic Vocal Fold Models, Cooper B. Thacker

Theses and Dissertations

The purpose of this research was to study perfusion pressure-flow relationships in self-oscillating synthetic poroelastic vocal fold (VF) models before, during, and after vibration. This was accomplished by developing a custom ultra-soft poroelastic material, incorporating the poroelastic material as the cover layer in a synthetic VF model, and studying the model vibratory response and the flow rate of fluid perfused through the cover layer while undergoing flow-induced vibration. The custom ultra-soft poroelastic material was developed using the method of direct templating with sucrose spheres as the sacrificial template and silicone as the infiltration medium. The average modulus of elasticity of …

A Game Theoretical Approach To Optimal Pitch Sequencing, William Melville

Theses and Dissertations

This paper presents a game theoretical solution to the difficult challenge of optimal pitch sequencing. We model the batter/pitcher matchup as a zero-sum game and determine the equilibrium strategy for both the pitcher and batter. We conclude that the Stackelberg equilibrium and our newly defined decision point equilibrium serve as effective pitch sequencing strategies.

Experimental Validation Of A Vibration-Based Sound Power Method, Trent P. Bates

Theses and Dissertations

A vibration-based sound power (VBSP) measurement method is appealing because of its potential versatility in application compared to pressure- and intensity-based methods. The VBSP method is based on the well-known elementary radiators approach and is reliant on the acoustic radiation resistance matrix. Previous research has developed and validated the VBSP method for flat plates and cylinders. This thesis details work on extending the VBSP method to arbitrarily-curved structures. The approach of computing surface normal velocities from 3D velocity data measured by a scanning laser Doppler vibrometer (SLDV) is presented. This approach is validated with experimental sound power results of a …

Dorothy Wordsworth, Religion, And The Rydal Journals, Emily Stephens Kasper

Theses and Dissertations

Dorothy Wordsworth’s religious practices continued to evolve throughout her life. She was baptized Anglican, but after her mother’s death she resided with her mother’s cousin, where she practiced Unitarianism. When she later moved in with her uncle, she embraced evangelical Anglicanism. Records of her religious beliefs in her twenties are scarce, as after moving to Racedown with her brother William in 1795 and throughout her years living in Alfoxden, she rarely wrote of her involvement with organized religion. Only in the 1810s while at Grasmere did Dorothy Wordsworth begin to record a gradual return to church attendance. Concerning her religious …

Rigorous Computation Of The Evans Function, Devin Mcghie

Theses and Dissertations

We develop computer-assisted methods of proof for rigorous computation of the Evans function in order to prove stability of traveling waves. We use the parameterization method, series solutions, and the Newton-Kantorovich Theorem to obtain precise, rigorous error bounds for the numerical solution of the ODE used in the construction of the Evans function. We demonstrate these methods on a scalar reaction-diffusion model and on the Gray-Scott model.

Factors That Influence The Recruitment And Retention Of Civil Engineers, Gina Young Souriac

Theses and Dissertations

With a growing demand for civil engineers in the United States, understanding factors that influence students to choose civil engineering (CE) as a major in college, pursue an M.S. degree in CE, and persist in the CE industry can lead to valuable insights for recruitment and retention of future and current civil engineers. Additionally, understanding factors that prominently influence male and female civil engineers to persist in and depart from CE, separately, can lead to valuable insight towards improving focused recruitment and retention of both genders. This thesis includes three research studies that identify, analyze, and discuss these important factors. …

Travel Across The "Narrow Neck Of Land", Matthew Roper

Insights: The Newsletter of the Neal A. Maxwell Institute for Religious Scholarship

In recent years a number of Book of Mormon scholars have associated the "narrow neck of land" mentioned by Mormon with the Mexican Isthmus of Tehuantepec. Mormon states that it was approximately "a day and a half's journey for a Nephite, on the line Bountiful and the land Desolation, from the east to the west sea" (Alma 22:32). This was the speed "for a Nephite," and presumably a group of people or even a non-Nephite might take longer. Moreover, since Mormon was speaking of a fortified line of defense along which communication would be desirable, the phrase "for a Nephite" …

Sound, Stories, And Psychology: The Perceptions And Motivations Of Audiobook Consumption, Ellice K. Tan

Theses and Dissertations

The demand for audiobooks is higher than ever--and increasing each year, surpassing the growth rate of electronic books, print books, and the US economy overall. Audiobooks have long been used to aid adolescent and struggling readers; however, recent studies have revealed that the majority of audiences consume audiobooks for the purpose of entertainment and relaxation. Despite this, much of the research available on audiobooks still applies to audiobooks as they are used in education. The purpose of this study was to understand the attitudes, opinions, and beliefs of people who love listening to audiobooks. The study was conducted using Q …

Understanding Gendered Hierarchy In Highly Religious Couples, Jolyn C. Schraedel

Theses and Dissertations

Although religious beliefs often associate with gendered hierarchy in sociological studies, very few studies have examined religion and gendered hierarchy within intimate relationships. This study used an exemplary sample to explore how religious, heterosexual married couples view and possibly practice gendered hierarchy. Interviews from 77 highly religious, highly satisfied couples provided insight into the following themes: (1) the potential harm of hierarchy, (2) misunderstanding hierarchy, (3) rejection of hierarchy, and (4) acceptance of hierarchy. For couples who expressed acceptance of hierarchy, further exploration revealed subthemes explaining how they conceptualized this practice. Subthemes included (4a) mutual submission, (4b) joint discussion, and …

Semi-Differentiation Of Reversible, Soluble-Insoluble Potential Sweep Voltammograms, Tyler Williams, Ranon Fuller, Cameron Vann, Devin Rappleye

Faculty Publications

Semi-differentiation, or convolution as it is sometimes known, is a mathematical technique commonly used to disentangle overlapping peaks in cyclic or linear sweep voltammograms. However, this technique is often misapplied due to misunderstandings of fractional calculus. Additionally, rigorous treatment and validation of the theory of semi-differential analysis of reversible, soluble-insoluble electrochemical reactions is lacking. Peculiarities of semi-differentiation are explored; theoretical relations for semi-differentiated voltammograms are given; the exponential nature of the theoretical curve is explored; theoretical relations are compared to experimental voltammograms for AgNO₃ in 1 M nitric acid at 298 K, NiCl₂ in LiCl at 974 K, …

Ecuadorians In The Sacramento California Area: Attitudes And Language Maintenance, Jacob M. Strawn

Theses and Dissertations

The present qualitative study investigated Spanish language maintenance among a familial/friend group of ten Ecuadorians that live in Northern California. The participants completed a survey and participated in an interview from which I retrieved information about the importance of Spanish and English, their self-reported confidence in Spanish and English, language attitudes, language use in private/familial contexts, and language use in public/social contexts. Previous studies regarding language maintenance and language shift in California were primarily focused on the Mexican-American population. California has the fourth largest population of Ecuadorians in the United States, yet there are no maintenance and shift studies for …

Testing Methodologies And Results Of Radiation Induced Soft Errors For A Cots Sram, Fram, And Soc, Wesley Raymond Stirk

Theses and Dissertations

Methods for testing commercial off-the-shelf (COTS) digital devices at varying levels of complexity is presented and discussed as well as the results for testing a COTS SRAM, FRAM, and SoC using these methodologies in a pulsed dose rate environment at Little Mountain Test Facility (LMTF) and neutron testing at Los Alamos Neutron Science Center (LANSCE). Investigations at LMTF revealed a dependence in all three devices on the integrated dose of a single pulse of radiation, implying that the duration of radiation plays a significant role in the response.

Theses and Dissertations

Objective: The aims of our present study were to develop a valid and reliable survey framed around the social cognitive theory, which would evaluate internal and external factors associated with food insecurity from the student's perspective, and to test the survey with a multi-state population. Design: The College Perspectives around Food Insecurity (CPFI) survey was developed through several revision and improvement steps using a mixed methods approach. In Phase 1 (2018-2019), data were translated into survey items and assigned to a theoretical concept (personal, behavioral, or environmental) in the social cognitive theory. In Phase 2 (2019-2020), content validity testing occurred …

A Large-Scale Survey Of Brown Dwarf Atmospheres, Savanah Kay Turner

Theses and Dissertations

Brown dwarfs are substellar objects that fall in-between the smallest stars and largest planets in size and temperature. Due to their relatively cool temperatures, the atmospheres of these 'failed stars' have been shown to exhibit interesting properties such as iron, silicate, and salt clouds. Theoretical atmospheric models based on known physics and chemistry can be used as tools to interpret and understand our observations of brown dwarfs. I have fit archival and new infrared spectra of over 300 brown dwarfs with atmospheric models. Using the parameters of the best-fit models as estimates for the physical properties of the brown dwarfs …

Rfssw Behavior Prediction Using A Numerical Model, Evan Robert Berger

Theses and Dissertations

A two-dimensional axisymmetric thermo-mechanical model of the Refill Friction Stir Spot Welding (RFSSW) process was developed and validated with experimental data. Welding temperatures, tool forces, and material flow including defect formation, were accurately predicted by the model. Qualified repair techniques are critical for successful implementation of a welding process for use on large weldments with a significant number of spot joints, and this work demonstrates a repair technique for RFSSW that is validated both experimentally and numerically. Repaired properties are shown to exceed 90% of the original mechanical properties of the RFSSW process. RFSSW has different process parameters for every …

The Rhetoric Of Teaching A Crisis: Incorporating Rhetorical Pedagogy Into Crisis Communications Textbooks, Maren Louise Johnson

Theses and Dissertations

A crisis is a pivotal moment for a company, and having prepared communicators can impact the reputation and financial state of a company. But there is currently a gap in learning how to manage a crisis and performing in the workplace. To explore this problem, I analyzed the four most popular textbooks in crisis communications and analyzed how they used theory to help students craft a fitting response to a crisis. My thesis recommends incorporating rhetorical theory, specifically the theory of the rhetorical situation, to bridge theory and practice and provide students with flexible theory to learn how to respond …
