The Manhattan Collection: A Study On Furniture Design, Gabriel Anderson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

I have designed a series of pieces of furniture that all share some key similarities, not in form or even style (though my personal aesthetic will be seen in all of them), but rather in materials. All of my pieces use a combination of metal, wood, and stone. Obviously, this is not remarkable as these materials have been used to build furniture for as long as furniture has been built. However, I have endeavored to explore how these materials can interact with one another within a piece of furniture. My goal was to create furniture where the materials do not …

Tutorial For Using The Center For High Performance Computing At The University Of Utah And An Example Using Random Forest, Stephen Barton

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Random Forests are very memory intensive machine learning algorithms and most computers would fail at building models from datasets with millions of observations. Using the Center for High Performance Computing (CHPC) at the University of Utah and an airline on-time arrival dataset with 7 million observations from the U.S. Department of Transportation Bureau of Transportation Statistics we built 316 models by adjusting the depth of the trees and randomness of each forest and compared the accuracy and time each took. Using this dataset we discovered that substantial restrictions to the size of trees, observations allowed for each tree, and variables …

Enhancement Of Volumetric Specific Impulse In Htpb/Ammonium Nitrate Mixed Hybrid Rocket Systems, Jacob Ward Forsyth

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Hybrid rocket systems are safer and have higher specific impulse than solid rockets. However, due to large oxidizer tanks and low regression rates, hybrid rockets have low volumetric efficiency and very long longitudinal profiles, which limit many of the applications for which hybrids can be used. This research investigates a method for increasing the volumetric efficiency and improving the form factor of hybrid rocket systems by a non-combustible load of solid oxidizer to the hybrid fuel grain. Including such oxidizers increases the regression rate of the fuel and lowers the amount of fluid oxidizer needed for optimal combustion. This type …

Econometric Modeling Of The Public Grazing Fee's Impact On The U.S. Sheep Industry, Ryan C. Feuz

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The U.S. sheep and wool industry is one of the oldest agricultural industries within the country. Since the mid 1940’s the industry has witnessed dramatic annual declines in sheep inventories. Many factors have contributed to the decline of the sheep industry including declining consumption of lamb and mutton, the growth in man-made fiber use, scarcity of labor, and predator losses. The U.S. congress has attempted to slow this decline throughout the years with various policy including the use of wool marketing loan programs. Such programs are intended to help bring stability as well as to mitigate price risk within the …

Scholarship On Robert Burton's The Anatomy Of Melancholy, Matthew Bishop

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The history of scholarship on Robert Burton’s The Anatomy of Melancholy will be explored in this thesis, beginning with a biographical background of Robert Burton and a brief description of The Anatomy of Melancholy. The overall arc of scholarship on Burton’s text began with a wave of early popularity in the seventeenth century, followed by a period of critical neglect in the eighteenth century when no new editions of the book were published. A renewed interest in the Anatomy in the nineteenth century led to a flurry of Burton studies in the twentieth century. The major trend in Burton …

On The Propagation Of Atmospheric Gravity Waves In A Non-Uniform Wind Field: Introducing A Modified Acoustic-Gravity Wave Equation, Ahmad Talaei

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Atmospheric gravity waves play fundamental roles in a broad-range of dynamical processes extending throughout the Earth’s neutral atmosphere and ionosphere. In this paper, we present a modified form for the acoustic-gravity wave equation and its dispersion relationships for a compressible and non-stationary atmosphere in hydrostatic balance. Importantly, the solutions have been achieved without the use of the well-known Boussinesq approximation which have been used extensively in previous studies.

We utilize the complete set of governing equations for a compressible atmosphere with non-uniform airflows to determine an equation for vertical velocity of possible atmospheric waves. This intricate wave equation is simplified …

The African American Community In Ogden, Utah: Teaching Local History Within A National Framework, Michelle Braeden

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Historical Background:

Beginning in 1869, the newly built Union Station in Ogden Utah became a major terminal for the transcontinental railroad. Around that same time George Pullman began recruiting emancipated slaves as employees on his luxury railroad cars. As a result a sizeable number of African Americans began working on the railroad. Many African Americans found residence in Ogden since it was a major railroad hub. As a result a small African American neighborhood that was six blocks long and two blocks wide formed in the city.[1] Businesses and organizations formed to support the emerging African American community within …

Suicide And Disability: Three Different Analyses Of A Nation-Wide Sample Of American Adults, Emily M. Lund

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Suicide is a major public health issue and the 10^th leading cause of death in the U.S. People with disabilities are one group that may be at high risk for suicide. This dissertation presents three studies that examined suicidal thoughts and behaviors in a national sample of individuals with and without disabilities. They also examined the ways in which depression scores and sociodemographic factors such as gender, religion, race, and employment, interact with disability status to influence suicidality. I found that people with disabilities reported more suicidal thoughts and suicide attempts and were more likely to believe that they …

Characterization Of The Substrate Interactions And Regulation Of Protein Arginine Methyltransferase, Yalemi Morales

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Protein arginine methylation is a posttranslational modification catalyzed by the family of proteins known as the protein arginine methyltransferases (PRMTs). Thousands of methylated arginines have been found in mammalian cells. Many targets of arginine regulation are involved in important cellular processes like transcription, RNA transport and processing, translation, cellular signaling, and DNA repair. Since PRMT dysregulation has been linked to a variety of disease states, understanding how the activity of the PRMTs is regulated is of paramount importance. PRMT1 is the predominant PRMT, responsible for about 85% of all arginine methylation in cells, but very little is known about how …

The Effect Of Prosody On Preschool Children’S Emotional, Cognitive, And Behavioral-Eye And Behavioral-Body Engagement During Story Time, Trevor Rowe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many children have insufficient early literacy experiences and fail to obtain proficient emergent literacy before they enter kindergarten. Reading to young children has been positively linked to improving their emergent literacy. Numerous factors influence how engaged children are while being read to including the adult’s prosody, receptive vocabulary, and the home literacy environment. Using a quantitative quasi-experimental design, this study sought to understand the association among prosody, child engagement (emotional, cognitive, behavioral-eye, and behavioral-body), receptive vocabulary, and the home literacy environment. The sample included 76 3- to 5-year-old children from local child care centers and their parents. To understand the …

Best Practices For Volume Flow Rate Measurements Using Piv At The Exit Of A Turbulent Planar Jet, Rick Cressall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Particle image velocimetry (PIV) is used to make volume-flow-rate measurements at the exit of a turbulent, planar nozzle. The objective of this report is to assess a range of data acquisition and processing parameters. Data is acquired for volume flow rates of Reynolds numbers between 10,000 and 100,000 for both two-component (2C) and stereo PIV. The parameters are systematically changed one at a time and evaluated using differences in uncertainty, calculation time, and volume- flow-rate deviation. Data acquisition parameters follow the trends of previous work. A multitude of processing parameters were varied for several PIV processing methods. Recommendations for each …

Laboratory Experiences In Mathematical Biology For Post-Secondary Mathematics Students, Matthew Lewis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In addition to the memorization, algorithmic skills and vocabulary which is the default focus in many mathematics classrooms, professional mathematicians are expected to creatively apply known techniques, construct new mathematical approaches and communicate with and about mathematics. We propose that students can learn these professional, higher level skills through Laboratory Experiences in Mathematical Biology (LEMBs) which put students in the role of mathematics researcher creating mathematics to describe and understand biological data. LEMBs are constructed so they require no specialized equipment and can easily be run in the context of a college math class. Students collect data and develop mathematical …

Statistical Techniques To Model And Optimize Performance Of Scientific, Numerically Intensive Workloads, Steena Dominica Steven Monteiro

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Projecting performance of applications and hardware is important to several market segments—hardware designers, software developers, supercomputing centers, and end users. Hardware designers estimate performance of current applications on future systems when designing new hardware. Software developers make performance estimates to evaluate performance of their code on different architectures and input datasets. Supercomputing centers try to optimize the process of matching computing resources to computing needs. End users requesting time on supercomputers must provide estimates of their application’s run time, and incorrect estimates can lead to wasted supercomputing resources and time. However, application performance is challenging to predict because it is …

In particular, this thesis seeks to develop an algorithm that can successfully remove a moving teacher from the whiteboard, so that the writing on the whiteboard may be fully visible to the audience.

In this thesis, some prior works related to this problem are studied to understand the basic principles of adaptive background modeling, or removing the foreground from a background with occasional changes in a video sequence. …

Evaluation Of The Shelf-Stability Of A High-Carotenoid Breakfast Food And Its Impact On Skin Carotenoid Levels, Dawn L. Reed

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Carotenoids are pigments found throughout nature in a large variety of plants including fruits and vegetables (F/V). Carotenoids provide much of the color we see in nature but are perhaps most noticeable in plants with yellow, orange, or red flesh. Carotenoids are antioxidants that serve as a protection against harmful ultraviolet radiation and other free radical producing processes in the body and in plant tissues. Once consumed, carotenoids are deposited in the skin, particularly in fatty tissue. Raman resonance spectroscopy (RRS) can be used to quantify skin carotenoid levels and has been proven a good indicator of F/V consumption. A …

Oocyte Quality: Molecular Constituents Altered In The Oocyte Due To Various Environmental Factors, Lindsay Cox

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An estimated 1.6 million American couples struggle with infertility. Some causes for poor fertility can be clearly defined but in many instances, subfertility is unexplained. Poor oocyte quality is now considered to be a main contributing factor for many causes of infertility. Good oocyte quality is crucial for many processes including embryo development and maintaining pregnancy. There is a possibility that any alterations to the oocyte can have long lasting effects on embryo development and the health of the offspring. The oocyte is very sensitive to any perturbations to its surrounding environment. Transcripts for apoptosis inhibitors and epigenetic modifiers were …

Investigating And Improving Bridge Management System Methodologies Under Uncertainty, Minwoo Chang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation presents a novel procedure to select explanatory variables, without the influence of human bias, for deterioration model development using National Bridge Inventory (NBI) data. Using NBI information, including geometric data and climate information, candidate explanatory variables can be converted into normalized numeric values and analyzed prior to the development of deterministic or stochastic deterioration models. The prevailing approach for explanatory variable selection is to use expert opinion solicited from experienced engineers. This may introduce human influenced biases into the deterioration modeling process. A framework using Least Absolute Shrinkage and Selection Operator (LASSO) penalized regression and covariance analysis are …

Simple Soil Quality Tests And Organic Management Practices For Orchards In The Intermountain West, Esther Oline Thomsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil health is often overlooked as a long-term management strategy as growers face an increasing number of short-term management challenges in the Intermountain West. The costs of inputs are rising and water resources are becoming more limited. Soil with poor health typically requires more amendments and fertlizers to meet crop needs. Soil health tests can help reveal management practices that reduce soil health, as well as those that improve soil health. Practices known to improve soil health are reduced to no tillage, cover crop use- especially legumes, and addition of mulch and other organic materials. Soil health testing is not …

An Evaluation Of Fading Procedures On The Effects Of Children Using Activity Schedules To Play On The Playground Appropriately, Kylee Lewis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Children with autism often have difficulty playing appropriately and independently. Activity schedules have been shown to be effective at teaching children with autism to play. Some individuals with autism engage in repetitive behaviors, especially on the playground. A previous study showed that activity schedules were effective at reducing repetitive or patterned behavior on the playground by teaching three students with autism to play appropriately and independently. This study investigated the effects of fading procedures on teaching independent and varied play skills to young children with autism during free play on the playground.

The Effects Of Rootstock, Scion, Grafting Method And Plant Growth Regulators On Flexural Strength And Hydraulic Resistance Of Apple, Stuart W. Adams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The apple rootstock ‘Geneva^® 41’ (‘G.41’), is desirable for its resistance to fire blight, Erwinia amylovora, while producing high yields. However, ‘G.41’ and other Geneva^® selections tend to form weak graft unions in the nursery that are susceptible to breaking in the wind, at harvest, or during shipment. In order to understand and remedy this graft union weakness, six scions (‘Fuji’, ‘Gala’, ‘Honeycrisp’, ‘McIntosh’, ‘Pink Lady’, and ‘Scilate’) by seven rootstocks (‘G.41’, ‘G.935’, ‘G.214’, ‘G.11’, ‘M.9-NIC 29’, ‘B.9’ and ‘EMLA 26’), by two grafting methods (chip bud and saddle graft) in a factorial design were tested for graft …

Language Brokering Consequences As A Function Of Development, Brent M. Gage

Undergraduate Honors Capstone Projects

Language brokering can be defined as a child mediating linguistically for a parent or other adult figure, either in spoken or written communication. This situation is a common occurrence among migrant and refugee families as children tend to acquire a new language at an accelerated rate in comparison with adults. As the immigrant and refugee populations continue to grow in comparison with native groups within the United States, it is increasingly important to understand the phenomenon of child language brokering. Moreover, it is particularly relevant to understand how the expectations for and consequences of language brokering may help to shape …

Diversity Education: Are We Preparing Teachers To Teach All Learners?, Lindi Andreasen

Undergraduate Honors Capstone Projects

Five hundred twenty-three preservice teachers from six different preparation programs completed the diversity and multicultural perspectives portion of the Professional Teaching Knowledge and Skills Survey (PTKSS) to determine their feelings of multicultural efficacy at the end of their program and again after their first year of teaching. Statistical analysis revealed that preservice teachers rate their capability to teach diverse students as "adequate" to "well" on a 5 point Likert type scale (M=35.28, possible Range=0-50), with no significant drop in self-efficacy after one year of teaching (M=34.09). However, individual item means did drop consistently between the preservice and inservice stages, and …

A Pilot Trial Of The Effectiveness Of Acceptance And Commitment Therapy Self-Help For Problematic Pornography Viewing, Scott Thane Heninger

Undergraduate Honors Capstone Projects

Although problematic pornography viewing (PV) is quite prevalent (Carroll et al., 2008), very few studies have been done to test treatments addressing this issue. Preliminary research indicates Acceptance and Commitment Therapy (ACT) is a promising potential treatment for problematic pornography viewing, but this has only been evaluated in face-to-face therapy trials to-date. This study sought to determine the effectiveness of a general ACT self-help book on PV. A sample of 19 participants were recruited and given a copy of the book with directions to read and apply its principles over the course of 8 weeks. Assessments were completed at baseline, …

Measuring The Effects Of High-Altitude Flight And Upper Atmospheric Radiation On Muscle Cells, Annelise Dykes

Undergraduate Honors Capstone Projects

There are several physiological barriers to long-term space travel, including the effects of launch, landing, and microgravity on muscle cells. A payload capsule was designed to maintain cell growth during a high altitude balloon flight to model some of these physiological processes. Murine muscle cells (strain C2C12) were cultured and launched in a capsule on a balloon satellite in November 2016. Cells were monitored for changes due to temperature, flight motion, radiation, and gravity differences by quantifying cell characteristics before and after the flight using physical measurements and cell viability. Instruments were selected to monitor flight data, and a payload …
