Agent Based Terrain Generator: Cruthú, Lawrence L. O'Boyle

Masters Theses

Terrain generation models are applied in different industries and fields of study. Current techniques assist in planning transportation networks, visualizing population migrations, conducting epidemiology research, and training self-driving cars and drones. Many current applications and research models generate complex realistic artifacts, e.g., trees, rivers, coastlines, populations, and even cities. Unfortunately, most of these techniques are described and implemented separately. Techniques do not work together to generate a complete holistic view. This thesis proposes a model, Cruthú (Gaelic for "creation"), that provides a novel platform allowing for complete world generation by integrating existing research and algorithms. The model is inspired by …

The Relationship Between Neuroticism, Self-Esteem, And Disordered Eating Attitudes: Examining The Health At Every Size Theory, Liana Cho

Masters Theses

Background. In the modern day treatment of overweight/obesity, conflicting recommendations regarding treatment have been released by the Academy of Nutrition and Dietetics (AND) and advocates of the Health at Every Size (HAES) movement. While the AND have indicated their support for self-monitoring practices, such as keeping a food diary or tracking calories, HAES advocates have claimed that these restrictive practices may result in increased disordered eating tendencies and poor self-esteem.

Subjects. The participants for this study included 410 students at Grand Valley State University. Almost 80% of participants were female, and just over 85% of participants identified as white. …

Is Tpmt Testing A Predictor Of Duration Of Use Or Long-Term Benefit Of Thiopurine Agents?, Shatoya R. Wilson

Masters Theses

Background: Inflammatory Bowel Disease (IBD) affects as many as 1.3 million Americans and includes both ulcerative colitis (UC) and Crohn’s disease (CD). Recent practices have moved towards using immunomodulators early in the course of disease to prevent disease progression. Patients have shown improved outcomes on immunomodulators compared to aminosalicylates, and reduced risk for tachyphylaxis compared to corticosteroid treatment. Thiopurine agents such as azathioprine and 6-mercaptopurine are immunomodulators often used to treat IBD. Unfortunately, many patients experience cytotoxicity from thiopurine use. Recent studies have shown that patients deficient in thiopurine-S-methyltransferase (TMPT), produce an overabundance of the therapeutic end product, 6-thioguanine nucleotide …

The continued development of modern-day vehicles has allowed innovators to shape their design to meet the consumer’s requirements. Vehicles have become faster and larger to accommodate more passengers and their belongings. The increased popularity of Light Trucks or Vans (LTVs) and Sports Utility Vehicles (SUVs) elevated their sales to approximately 50% of all vehicles sold in the United States by 1999 [1]. These advancements have created a high-energy world, which poses a serious threat to the ever-growing population. Unprotected pedestrians come in all too frequent contact with these vehicles creating the potential for high-energy blunt force trauma. This thesis aims …

The Relationship Between Feeding Type And Temporomandibular Joint Morphology In Superfamily Musteloidea, Travis L. Garvin

Masters Theses

Many studies have focused on the soft tissue analysis of carnivores and have demonstrated a relationship between feeding biomechanics and feeding types. Herbivores and omnivores rely heavily on anteroposterior and helical movement of the mandible and teeth for the breakdown of fibrous foods resulting in a flat mandibular fossa while the function of the carnivore TMJ is different, as they need a much stable joint for ripping and tearing of the flesh. I aim to look at whether the bony morphology of the temporomandibular joint (TMJ) can be directly related to feeding type, specifically in the superfamily Musteloidea. I sampled …

Analysis Of Growth And Prevalence Of Malnutrition During Total Parenteral Nutrition Weaning: A Methodological Demonstration, Lauren Ashley Kane

Masters Theses

Background: Total Parenteral Nutrition (TPN) is a life-saving intervention which provides nutrition to premature infants with immature gut functioning. Though essential for nutrition provision in the first days of life, TPN is not without risk. Therefore, it is important to introduce feedings into the gut and to wean off TPN when able. During this weaning phase, calorie and protein deficits have been observed to occur. Very few studies have investigated TPN weaning periods, and there are no studies on malnutrition associated with the TPN weaning period in premature infants.

Methods: This study employed a retrospective chart review, with medical …

Design And Testing Of A Sheath Device To Secure Rotator Cuff Anchors In Osteoporotic Bone, Alissa Smith

Masters Theses

A rotator cuff tear is a common injury that affects many elderly people. These tears vary in severity, with moderate to severe tears requiring surgery. In rotator cuff surgery, bone anchors are used to re-attach the supraspinatus tendon to the humerus. This surgery is difficult in many older patients because aging bones become osteoporotic, or soft, and thus inadequate for securing bone anchors. Studies confirm that osteoporotic bone is a contributing factor of implant failure. A finned sheath concept was designed, developed, and tested to ensure securement of the bone anchors during and after rotator cuff repair. The sheath interacts …

Technology And The Printed Book: Pursuing A Holistic Human Experience With A Sacred Text, Rachel Dugan

Masters Theses

There exists a sort of gravitas attached to a book that is printed and bound by hand that gets lost on the production line. When holding a hand-printed (or hand-written), hand-bound codex next to a mass-produced book, there is between the two a visible and tactile difference in quality and harmony between form and content. With the modern technological advancements now available, how can the craftsmanship and beauty — the gravitas — evident in books of the past be replicated in a way that is aesthetically pleasing, harmonious in message, and reflective of the present time? As objects, books are …

The Determinants Of Affect, Emotional Arousal, And Autobiographical Memories On Music-Evoked Nostalgia, Alycia Sterenberg

Masters Theses

The purpose of this study is to further explore both person – level and context – level constructs established by Barrett et al. (2010) in relation to music-evoked nostalgia. This study also measures the strength of the relationship between self-reported arousal levels and electrodermal activity (EDA) as well as if they are good predictors of nostalgia. Methods include listening to personalized playlists to elicit feelings of nostalgia while electrodermal activity collects changes in arousal. Participants then answer questions of song familiarity, pleasure, arousal, and autobiographical salience to gather context – level constructs. Results indicate that both person – level and …

Exploring The Impact Of Pretrained Bidirectional Language Models On Protein Secondary Structure Prediction, Dillon G. Daudert

Masters Theses

Protein secondary structure prediction (PSSP) involves determining the local conformations of the peptide backbone in a folded protein, and is often the first step in resolving a protein's global folded structure. Accurate structure prediction has important implications for understanding protein function and de novo protein design, with progress in recent years being driven by the application of deep learning methods such as convolutional and recurrent neural networks. Language models pretrained on large text corpora have been shown to learn useful representations for feature extraction and transfer learning across problem domains in natural language processing, most notably in instances where the …

Enabling Robust Distributed Real-Time Hybrid Simulation Method And Expanding Its Applications In Floating Wind Turbine Systems, Mehmet Cinar

Masters Theses

Real-time hybrid simulation (RTHS), which integrates physical experiment and numerical simulation, plays an essential role in understanding the time-dependent behavior of structures when subject to hazardous loadings. On the other hand, RTHS might not yield accurate results for complex structural systems due to experimental and computational limitations. Distributed real-time hybrid simulation (dRTHS), which takes the advantage of distributed laboratory facilities using network communications, was proposed and proven to address some limitations in RTHS. During dRTHS, Internet delay due to the network communication is added to the actuator delay in RTHS, which may cause inaccurate results or even unstable tests. To …

Establishing Delay-Based Criteria For Installing Traffic Signals At Two-Lane Roundabouts, Oluwaseun Ayomide Adegbaju

Masters Theses

A roundabout is a circular intersection where drivers travel counterclockwise around a center island in the United States. Roundabouts can be more beneficial than the conventional intersections because they increase the capacity of the intersection and reduce delays and crashes at the intersection. However, the performance of roundabouts can be severely affected by unbalanced traffic flows among the approaches. While the resulting delays can be mitigated by installing traffic signals, there is a lack of clear criteria on when to install a traffic signal at a roundabout. This research focuses on establishing criteria for installing traffic signals at two-lane roundabouts …

Stereotypic Repetitive Hand Flapping Movement Detector Children With Autism, Subodh Ashok Bansode

Masters Theses

The prevalence of Autism Spectrum Disorder (ASD) has increased at a significant rate in recent years, especially in developed nations such as the United States, Japan, and South Korea. Extensive research is being carried out to study the behavioral characteristics of the disease. Children affected with autism tend to exhibit a spectrum of symptoms depending on the severity of the disease. These behaviors are primarily repetitive, self-stimulatory, and stereotypic behaviors such as hand flapping (i.e., repeatedly shaking their hands), body rocking (i.e., swaying their body back and forth), drumming, walking around in a confined space, and walking with shortened steps …

Tearing The Guts Out Of The Wehrmacht: A Re-Examination Of The Russo-German War, Randall Wells, Jr.

Masters Theses

Nazi Germany invaded the Soviet Union on 22 June 1941. Hitler’s plan to annihilate Germany’s Eastern neighbor and populate the vast Russian expanse with his own people was as ambitious as it was adventuristic. Although it began successful, the Russo-German War quickly devolved into a quagmire as Russian troops outfought their German opponent and beat them back to Berlin. Contrary to prevailing historiography, the Wehrmacht’s loss on the Eastern Front cannot be solely attributed to a failure to equip German troops with proper winter clothing, an inadequate logistics network or Hitler’s interference in military decisions. For an army that had …

Sinister Subshade: The Revival Of The Ku Klux Klan In Modern America, Taylor Ashton Spicer

Masters Theses

Through the implementation of qualitative analysis this study purposes to discover if there exists possible correlation between President Trump’s assent to power and the increasing legitimacy of the Ku Klux Klan. Using Ernest Bormann’s (1972) Fantasy Theme Criticism, the Knights Party official website and the Donald J. Trump official website are systematically analyzed for dramatis personae (character), setting and action. The rhetorical visions compiled from each analysis are compared employing Ernest Bormann’s (1980) Symbolic Convergence Theory. Resulting analysis suggests little to no correlation between the two movements. The two websites provide very different rhetorical visions with no overlap. The work …

The Origins And Uses Of The Three-Fifths Clause Related To Slavery And Taxation, William F. Hughes

Masters Theses

The Three-fifths clause of the 1787 U.S. Constitution is noted for having a role in perpetuating racial injustices of America’s early slave culture, solidifying the document as pro-slavery in design and practice. This thesis, however, examines the ubiquitous application of the three-fifths ratio as used in ancient societies, medieval governments, and colonial America. Being associated with proportions of scale, this understanding of the three-fifths formula is essential in supporting the intent of the Constitutional framers to create a proportional based system of government that encompassed citizenship, representation, and taxation as related to production theory. The empirical methodology used in this …

A New Formula For Voter Turnout, Elliot Pope

Masters Theses

This paper proposes a new, modified decision matrix for voter turnout: Likelihood of Voting = Personal Connection + Sense of Duty + Self-Interest – Difficulty in Voting – Sense of Apathy. It introduces a new variable, “Personal Connection.” This variable combines the important contributions of social pressure and canvassing research as a summary motivation of the two. In order to test this hypothesis, I complete an initial review of ANES data and a metanalysis of relevant literature. The conclusion is that there is enough data to support further research into the proposed formula and new variable for voter turnout.

C.S. Lewis And The True Myth: A Reconciliation Of Theology, Philosophy, And Mythology, Courage Lowrance

Masters Theses

C.S. Lewis was both a student of pagan philosophy and mythology and a Christian. He never was divided between these two pursuits in his life, though he gave the latter its proper priority. What allowed Lewis to keep this balance was his idea of the gospel as the True Myth, an idea that helped lead to his conversion and remained at the core of his thinking throughout his life. By this idea of True Myth, Lewis was able to not only unite the pagan myths to Christian truth, but also the rest of human thought as well. Thus, in order …

The Problem Of The Stigma Of Marxism For Christian Advocacy Writers Whose Focus Is Historical, Social Inequalities, Kandy Crosby-Hastings

Masters Theses

Christian advocacy writers seek to advocate on behalf of and empower the marginalized. Christian advocacy writers who focus on historical, social inequalities reveal oppressions from history in order to advocate for the oppressed in similar circumstances in today’s world. They must be willing to learn from all scholarship that reveals the hardship and oppression endured by the exploited of society. There is often a stigma associated with the use of Marxist sources for reasons that include Karl Marx’s own anti-religious, anti-Semitic, pro-revolution, and reductionist ideas and the later association of Marxism with Soviet Communism. Christian advocacy writers must understand both …

The New England Narrative, Cynnamon C. Mathis

Masters Theses

Though equally successful, noteworthy, inspiring, and crucial as the contributions to American Independence made by New England women patriots, the contributions made by North Carolinian women patriots are excluded from the history of America’s founding as a direct result of sectional nationalism.

This decidedly charged topic critically researches the philosophy of salvation doctrine, or soteriology, within major monotheistic religions. The highlighted problem is the Messiah conundrum, with critical research on each doctrine for epistemological significance of a savior and their beliefs surrounding salvation. This mystery of where, or who humans turn to for salvation, is vitally important when considering the principle of sufficient reason in today’s hermeneutic and apologetic circles. The purpose fueling this thesis is the resolute documenting of beliefs of major …

Examining Keswick For Benefits To Chaplain Resilience Ministry, Caleb Walker

Masters Theses

The Keswick Convention movement, which began in Keswick, England in 1870 and emphasized deeper knowledge and experience of God, has often been criticized and marginalized in evangelical theological circles. The structure of the conferences, with an emphasis upon six major theological themes and their application for daily Christian living, seems to have value for many attendees in deepening their Christian life. This study examines the potential benefits of the Keswick themes with particular application to the military chaplaincy setting and the issue of spiritual resilience. By examining criteria for resilience (steadfastness, perseverance, courage, and recuperation) and utilizing a qualitative research …

Mathematical Modeling And Empirical Validation Of A Conceptual Exoskeleton For Astronaut Glove Augmentation, Joseph Kissling

Masters Theses

Space presents numerous difficulties for astronauts conducting their work, not the least of which is the spacesuit that is worn to protect them from space. It has long been known that a spacesuit is difficult to work in, especially the rigid and pressurized gloves that put strain on the astronaut's hands, frequently leading to injuries. Astronaut gloves inhibit more than 50% of their strength in some cases [1]. NASA and other space agencies have been working to alleviate these problems by attempting to mechanically augment the gloves to reduce the exertions of the astronaut. To date, no augmentation systems have …

College Self-Funding Predicting Deviant Behaviors, Blake A. Darling

Masters Theses

This study examines the effects of the source of college funding on student participation in four deviant behaviors: monthly binge drinking, monthly marijuana use, illicit drug use, and academic cheating. Using secondary data from a self-reported online survey conducted at a midwestern University, competing hypotheses based in general strain theory and social bond theory, were tested. Logistic regression analyses of the four deviant behaviors suggest that the source of college funding has a very limited effect. Only in the cases of marijuana use and illicit drug use were significant relationships observed; where students whose funding came from their parents were …

Use Of Fluorescein Dye For Characterizing Water And Solute Flux Across The Groundwater – Surface Water Interface, Ryan Nicholas Cascarano

Masters Theses

Quantifying groundwater discharge across the sediment—surface water interface remains a challenge due to streambed heterogeneity and the integration of disparate measurements over a continuum of spatial and temporal scales. In this study, mini-piezometers are first used to identify areas of groundwater discharge in lakes and streams, and micro-pulses of fluorescein dye are released at precisely known shallow depths as a conservative tracer. The use of fluorescein dye allows for visual dye detection regardless of light conditions, and measurements of dye concentrations over time using a fluorometer are used to generate high resolution breakthrough curves. Accurate determination of groundwater velocity and …
