Development Of Atomistic Machine Learning Approaches For Thermal Properties Of Multi-Component Solids And Liquids, Alejandro David Rodriguez

Theses and Dissertations

Currently, heat transfer in many industries is the limiting factor for innovation, especially in the energy sector. For example, maximizing thermal conductivity of ceramic coatings in power plant devices improves the overall electrical to thermal energy ratio, whereas minimizing thermal conductivity is required for desirable heat-to-electricity conversion in thermoelectric devices. As such, rapid discovery of new materials with extreme thermal conductivity values is quintessential for the near-future deployment of current and developing energy applications.

The vibrational properties of crystalline materials are essential for their ability to conduct heat. Fundamentally, the restorative atomic forces of displaced atoms are sufficient to represent …

Implementation Of A 3d Laser Profiler System Into A Non-Contacting Method For Rnt & Stress Measurements, Caio Neto Penna

Theses and Dissertations

Continuous welded rail (CWR) is susceptible to the development of internal forces in the rail due to thermal effects that can lead to track buckling. Railroads typically deal with the internal stresses in the rail through the inspection of the rail neutral temperature (RNT) which is the temperature at which the internal force is zero. The existing methods in the industry to measure RNT are contacting, destructive, disruptive to railroad operations, and ineffective. The proposed concept is a promising non-contacting, non-disruptive and reference-free technique to measure RNT and the stress state in the rail. The method is based on the …

Effect Of Variable Delays To Reinforcement On Skill Acquisition Of Tacts In Children With Autism, Ya-Chien Yang

Theses and Dissertations

Basic research has established that immediate reinforcement produces the best outcome when learning a skill. More recent research has followed, showing that even 8-10 seconds of brief delays may impair learning. In one of the few applied studies on this topic, Majdalany et al. (2016) showed that participants with Autism Spectrum Disorder (ASD) acquired tacts more quickly with immediate reinforcement, compared to delays of 6s and 12s. However, no research has examined variable delays to reinforcement, which may be more common in classrooms and clinics. Thus, the purpose of the proposed study was to expand previous research by examining variable …

Revisitng The Violence And Social Order Conceptual Framework: A Case Study Of China, Nur E Jannat Moon

Theses and Dissertations

The conceptual framework on violence and social order- by North, Wallis, and Weingast (2009)- categorizes societies into three groups based on how they foster competition, limit violence, and allow citizens access to political and economic organizations. This thesis critically examines this conceptual framework and highlights its drawbacks in explaining economic growth and development in the contemporary global context. This thesis identifies two specific areas of improvement in the conceptual framework of social order: first, by reconceptualizing violence, and second, by integrating the extent of personalism in political parties as critical determinants for categorizing social order. By demonstrating the intricate relationship …

Returning Home: The Thesis Of A Master, Yang Thai Vang

Theses and Dissertations

Over centuries, Hmong people have moved from mountain to mountain, home to home, country to country, crossing rivers and valleys in search of an escape from oppression. The Txiv Xaiv (Plig) ritual and chant has survived serial exodus and diaspora that Hmong people have experienced. This ritual encodes Hmong historical and cosmological understandings as an oral text, passed down from master to student, and performed at funerals to apply that understanding in the management of souls--ultimately to send them home. The Txiv Xaiv (Plig) serves as a glue, connecting the past generations to the generation of today and the generations …

Flying By Ml Or Cnn Inversion Of Affine Transforms, Lloyd Van Warren

Theses and Dissertations

This dissertation describes how to automate the reading of dials, gauges, and instruments using machine learning (ML) methods. This process can be described as analog to digital conversion through an air gap without any direct electronic connection. The goal is to convert the values of existing instruments into digital values for control and monitoring without requiring any intrusion, changes, or upgrades to the instruments being observed. Images of instrument faces can be distorted by various kinds of noise, but this can be overcome using a deep learning convolutional neural network (CNN) approach similar to handwriting recognition. One advantage of this …

Non-Zero Sum Sport: Pickleball And The Theory Of Coopetition, Max Arthur Manthou

Theses and Dissertations

An ethnography of the sport of pickleball was conducted over a span of 7 months in the United States. Findings are partly the result of the author’s journey from playing in the park to playing in the Pros—presented in autoethnographic terms—and partly the result of 11 semi-structured interviews with 13 avid pickleball players. The main contention of this study is that sport is non-zero sum, despite a tendency for sport to be considered in zero sum terms. The non-zero sum aspect of sport is argued to be the result of two main causes: one, sport is coopetive, in that it …

How Do Dispositional Mindfulness And Statistical Anxiety Affect Student Performance On An Exam?, Mario Diaz

Theses and Dissertations

The current study investigated if a specific disposition, mindfulness, offers an advantage for undergraduate students’ success on statistical exams by decreasing the impact of an academic-related strain, anxiety. Prior research utilizing state mindfulness has found evidence of this performance advantage, but it has yet to be investigated if dispositional mindfulness offers similar results. The current study found that dispositional mindfulness does impact one’s anxiety, but that relation does not offer a performance advantage for those with higher levels of mindfulness in comparison to those with lower levels of the disposition. To improve student success, engaging in mindfulness practices appears more …

High-Risk Fertility Behaviors: Impact On Child And Risks Of Maternal Mortality In Kenya, Mercy Chepkosgei Kiprop

Theses and Dissertations

Rapid population increase in Sub-Saharan Africa (SSA) over the last several decades and limited healthcare interventions have exacerbated child and maternal mortality. The maternal mortality ratio (deaths per 100,000 live births) in Sub-Saharan Africa accounts for at least 50 percent of maternal deaths globally. In 2020 alone, 5 million children under 5 years died in Kenya. Research also points out that, tragically, many of the mothers and children died of preventable or treatable conditions. Previous research has focused on biological or socioeconomic determinants of child mortality rather than their joint influences. In this study, we investigate the premise that all …

Does Chronic Low Back Pain Influence Breathing Mechanics And Diaphragm Positioning? A Pilot Study, Lindsey Wensel

Theses and Dissertations

Background and objective: Chronic low back pain (CLBP) is a complex musculoskeletal condition and often the source of the pain is not clear. A correlation has been found to exist between incidences of low back pain (LBP) and those with respiratory diseases such as COPD. This could give reason to believe that the sequence of events could be reversed, and LBP could elicit changes in respiratory function. The purpose of this study is to investigate if CLBP has an influence on breathing mechanics and the positioning of the diaphragm in the trunk. Methods: Volunteers were recruited between the ages of …

Friction And Heat Transfer Modeling Of The Tool And Workpiece Interface In Friction Stir Welding Of Aa 6061-T6 For Improved Simulation Accuracy, Ryan Melander

Theses and Dissertations

Friction stir welding (FSW) is a solid-state joining process that offers advantages over traditional fusion welding. The amount of heat generated during a FSW process greatly influences the final properties of the weld. The heat is generated through two main mechanisms: friction and plastic deformation, with friction being the larger contributor in a FSW process. There is a need to develop better predictive models of the heat generation and heat transfer in FSW. Almost all models seen in the literature validate temperature predictions on only one side of the tool/workpiece interface, thus ignoring possible inaccuracy that comes from incorrect partitioning …

Variability Among Individual Male Runners Influences Cumulative Loading More Than Foot Strike Type, Tamarie Trotter
