Characterizing The Risk Of Meteorite Ejecta To Future Lunar Surface Operations, Jacob Yates
Characterizing The Risk Of Meteorite Ejecta To Future Lunar Surface Operations, Jacob Yates
Theses and Dissertations
In-situ materials provided adequate shielding against the risk of meteorite ejecta for future lunar surface operations. Both regolith simulant and simulant-epoxy mixtures stopped simulated ejecta projectiles with velocities at or near lunar escape velocity. Those depth penetrations for those two in-situ related materials were shallow inside 3 cm and may prove to be influential in future mission planning of lunar surface operations. The lunar surface poses a potential risk from meteoroid ejecta for future lunar surface operations. The safety ramifications of long-term crewed missions for the Artemis program, NASA’s lunar program, are being investigated or reconsidered from the previous Apollo …

Impact Of Delphi-Developed Rubrics On Rater Consistency In 14 Cfr 141 Flight Training Assessment Environments, Lewis Robert James Archer
Impact Of Delphi-Developed Rubrics On Rater Consistency In 14 Cfr 141 Flight Training Assessment Environments, Lewis Robert James Archer
Theses and Dissertations
Pilot schools operating in accordance with 14 CFR 141 provide a substantial supply of pilots to the aviation industry. Recent high industry demand for pilots has created turnover among the flight instructor workforce, often considered an entry-level position used by aspiring aviators to build flight experience. This in turn means that check instructors, evaluators who are often selected from the more senior flight instructor population at a pilot school, are generally less experienced than in the past. Anecdotal evidence suggests that there is low consistency among these check instructors when conducting performance-based assessments. This study sought to determine the existing …

Directivity Improvement Of A Broad-Beam Patch Antenna By Means Of A Flat Metamaterial Lens, Tyler Midas
Theses and Dissertations
This thesis demonstrates the development of a flat metamaterial lens intended to enhance antenna directivity in RF applications. Development and evaluation was performed with ANSYS HFSS, where a theoretical convex lens model was developed and used as a basis for unit cell refractive indices of the metamaterial lens. The unit cell demonstrated in this study leverages the properties of a nested split-ring resonator merged with a center column. Adjusting the rings allow for refractive index optimization and effective beam focusing. The work presented also provides a 2x2 antenna array with a feed network, which enables the future work of bench …
Investigating The Impact Of Urban Areas On Quasi-Linear Convective Systems, Claiborne Wooton
Investigating The Impact Of Urban Areas On Quasi-Linear Convective Systems, Claiborne Wooton
Theses and Dissertations
Urban areas absorb and radiate energy at a higher rate compared to surrounding rural areas due to several factors, including an urban area’s tendency to have sparse vegetation and tree canopies along with high incidences of pavement. Urban areas have been shown to impact both the environment in which thunderstorms form (by altering thermodynamic, microphysical, and wind flow patterns) and the thunderstorms themselves; however, most of this previous work focused on isolated thunderstorms amid weak environmental vertical wind shear. This thesis analyzes how the structure of observed quasi-linear convective systems (QLCSs)—i.e., lines of thunderstorms—are altered as they pass over urban …
Petrophysical And Geomechanical Alterations During Supercritical Co2 Submerge: Laboratory Testing On Samples From The Middle Bakken, Ruichong Ni
Theses and Dissertations
The promising strategy of CO2 capture, utilization and storage (CCUS) aims to reduce CO2 emissions and tackle the pressing problem of global warming. Previous studies have demonstrated the importance of changes in petrophysical and geomechanical characteristics in assessing target formations' capacity to sequester CO2. Permeability is one of these characteristics that is essential to the movement of CO2 inside rock formations and has a direct effect on how well CO2 is sequestered. Existing methods calculate permeability by using effective stress, but they have made unpractical assumptions that the effective stress coefficient could be stable or gradually increase after CO2 exposure. …

Exploring Green Photochemical Reactions Of Bio-Based Heterocyclic Compounds: 4-Hydroxy-2(5h) Furanone And 2-Pyridone, Solmaz Asadi
Theses and Dissertations
The present work examines the photoreactivity of 4-hydroxy-2(5H)-furanone and 2-pyridone un-der varying conditions, with the aim of investigating how solvent and wavelength can influence their photochemical reactivity. In the first chapter, the photoreactivity of 4-hydroxy-2(5H)-furanone in its crystalline state was observed to undergo a [2+2] photocycloaddition reaction when exposed to UV-C light and led to a new cyclobutane containing dimer (CB-SA-1). More impressively, CB-SA-1 was determined to be stable at room temperature for two years. This method was solvent-free and catalyst-free offering an environmentally friendly method for synthesizing furanone deriva-tives. Further, in order to study the photoreactivity of 4-hydroxy-2(5H)-furanone in …

This study therefore investigates the feasibility …
Cyclical Musicians: Collegiate Music Students’ Experiences Of Instrumental Musicking Processes Across The Menstrual Cycle, Anne Marques Catarin
Cyclical Musicians: Collegiate Music Students’ Experiences Of Instrumental Musicking Processes Across The Menstrual Cycle, Anne Marques Catarin
Theses and Dissertations
Instrumental music researchers tend to focus on non-sex-specific health topics, such as posture (e.g., Garnett et al., 2022; Rousseau et al., 2023), musculoskeletal health (e.g., Mizrahi, 2020; Pratt et al., 2020), or neurological movement disorders (e.g., Altenmüller & Jabusch, 2010; Frucht, 2009). Despite the considerable extent of topics covered in musician health, the role of menstrual health in instrumentalists is currently underdeveloped. Using a case study design (Stake, 1995; Yin, 2014), I explored the unspoken experiences of collegiate instrumental music majors who menstruate, in an investigation to better understand the role of menstrual cycles in their musicking. For four months, …
An Investigation Into The Corrosivity Of Hydrocarbon Well Produced Water, Lucas James Jerylo
An Investigation Into The Corrosivity Of Hydrocarbon Well Produced Water, Lucas James Jerylo
Theses and Dissertations
Produced water has been the largest byproduct of oil and gas production since the inception of the industry. Historically, very little concern was exhibited over what was done with this water. In recent decades, environmental concern has increased oversight on what happens to this produced water. Produced water is injected into deep formations, but this volume is limited due to concerns over seismic activity spawned from this practice. Produced water can be recycled in agricultural and municipal industries but it must first undergo a time-consuming and expensive cleaning process. This has turned oil and gas operators to utilizing this water …

The Pdots were functionalized as …
Personality Across Realities: Correlations Between Personality Profiles And Preferences Within Roleplaying Games, Brittany Lee Mancha
Personality Across Realities: Correlations Between Personality Profiles And Preferences Within Roleplaying Games, Brittany Lee Mancha
Theses and Dissertations
Clinically maladaptive behaviors and personality types have been studied within gamers, both those who play video games and those who roleplay in tabletop games. However, the connection between personality types and the preferences of the players themselves in what and how they roleplay is just barely being studied. Personality traits, such as extraversion/introversion and motivation by pain or pleasure, may be both influencing the gameplay decisions and preferences of players, and vice versa. A total of 500 respondents completed the Millon Index of Personality Styles, Revised (MIPS-R), followed by a demographics survey and finally a survey assessing Dungeons and Dragons', …
The Positivity Principle: Investigating A School Administrator Training Series Designed To Promote Systemic Positivity, Catherine Gillach
The Positivity Principle: Investigating A School Administrator Training Series Designed To Promote Systemic Positivity, Catherine Gillach
Theses and Dissertations
Education has historically been recognized as a stressful profession, yet the Covid-19 pandemic (2020) paired with intensified socio-political influences have exacerbated educator stress, anxiety, and negativity, prematurely pushing more career educators to leave the profession. Teacher and principal pre-service preparation programs largely neglect to train educators in strategies for personally managing negative stressors, and negativity mitigation strategies are often overlooked as a critical facet of school climate and culture. Therefore, the purpose of this dissertation in practice was to examine the degree to which a school administrator training series could stimulate personal and systemic positivity within participants’ schools in a …
Handheld Multimodal Point Spectroscopy, Rgb Imaging, And Fusion Artificial Intelligence To Determine The Species And Freshness Of Fish Fillets, Mitchell Sueker
Handheld Multimodal Point Spectroscopy, Rgb Imaging, And Fusion Artificial Intelligence To Determine The Species And Freshness Of Fish Fillets, Mitchell Sueker
Theses and Dissertations
When fish species are mislabeled and the fish’s freshness is inaccurately represented, health, environmental, and economic problems can arise for both consumers and the fish industry. Fish are some of the easier foods to mislabel, as the processing of whole fish to fillets makes the visual identification of the species and freshness assessment more challenging. Due to the shortcomings of the current industry standards, confirmed by our interviews with over 20 professionals in all fish supply chain nodes, developing a system that can provide accurate and rapid on-site fraud detection is of necessity. In an attempt to meet these needs, …
