Aeroelastic Phenomena Of Fixed-Wing Aircraft In Transonic And Supersonic Flows Using A Tightly-Coupled Computational Approach, John C. Havenar

College of Graduate Studies: Theses & Dissertations

Aeroelastic phenomena encountered during flight have considerable effects on the aerodynamic characteristics of fixed-wing aircraft. Transonic aeroelastic phenomena are often characterized by unique flow features which have complex ramifications for aircraft in transonic flight. Computational study of high-speed aeroelastic phenomena requires a fully-coupled aeroelastic algorithm. A series of wing designs are studied with a computational finite volume method solver accompanied by a finite element method solver for the calculation of structural deformation. The computational model for the flow field is validated with experimental data. Modeled flight conditions include transonic flows with bordering subsonic and supersonic cases included for completeness. The …

Detecting Bearing Race Defects With Inductive Magnetic Reluctance Sensors And Artificial Neural Networks, Collin Daly

College of Graduate Studies: Theses & Dissertations

This work proposes a method of detecting physical damage to bearing races in a rotational assembly by means of magnetic reluctance sensors generating a signal from a rotating gear-tooth wheel. A nominally sinusoidal signal is generated based on the rotation of a gearwheel with regularly spaced voids and lands. Detection is based on the time variance of the signal periodically in relation to the gearwheel and the bearing damage. The purpose of this work is to propose a process to detect and classify bearing race defects using existing sensors and neural networks for hazardous area equipment applications.

Development Of A Measure Assessing Adolescent Aggression: The Aggressive Behavior Risk Assessment- Adolescent- Parent Report (Abra-A-Pr), Katherine Fallon

College of Graduate Studies: Theses & Dissertations

Although parent-report scales for general behavioral difficulties and aggression (e.g., verbal and physical aggression) exist, there are currently no measures assessing sexual behaviors in this context. Commonly, parent-report measures provide a few items relevant to behavioral aggression, and items encompassing sexually aggressive behaviors are frequently vague and non-specific in the actions being committed by the adolescent. The primary purpose of this project was to develop a comprehensive and multifaceted parent-report measure for aggressive behavior in adolescents. Three separate studies were conducted to evaluate the psychometric properties of the measure. Exploratory (EFA) and confirmatory factor analysis (CFA) were used to investigate …

Social Support In Black Individuals: The Moderating Effects On The Relationship Between Resilience And Well-Being, Imani Elise Crosby

College of Graduate Studies: Theses & Dissertations

Black individuals possess numerous strengths and positive contributions that build strong communities and cultivate psychological well-being (Biglan et al., 2012). However, much of the current literature focuses on hardships Black individuals face, skewing the larger discourse of their lived experience. This exclusive focus on adversity often neglects pathways by which Black people thrive and flourish. It is important to consider how Black experiences relate to a sense of well-being. Resilience, or the ability to “bounce back” from adverse experiences is linked well-being outcomes (APA, 2012). However, it is unknown whether the promotive effects of resilience directly contribute to well-being outcomes …

Functional Monitoring For Run-Time Assurance Of A Real-Time Cyber Physical System, Matthew W. Gelber

Theses and Dissertations

As cyber-physical systems (CPS) become more integrated into everyday life, the security of these systems must also be considered during their development due to their ever-increasing importance. With the growth of physical components in the system, more autonomous control requirements, and increased dependence on proper functionality, verifying system safety and correct operation becomes increasingly difficult. CPS have become more complex through the combination of additional hardware and the resulting interconnected software in many layers, each requiring unique security solutions. One example of such a safety-critical CPS embedded system is the Flight Control System (FCS) of an Unmanned Aerial System (UAS). …

The Patient Experience Of Language Discordance And Interpreter Services In The Emergency Department, Keri L. Baker

Theses and Dissertations

Background: Clear communication is critical to the interaction of a patient and medical provider. For non-English speaking patients, language discordance, described as the lack of proficiency in a shared language, with the medical team results in a poor patient experience and poor patient outcomes. The predominant solution to language discordance is the use of interpreter services, however these services are underused in the emergency department (ED). Studies examining underuse of interpreter services have primarily focused on the clinician and little is known about the patient’s influence on the use of interpreter services.

Methods: Semi-structured interviews were conducted with 12 Spanish-speaking …

Using Natural Language Processing To Understand The Lived Experiences Of People Identifying With Adhd: What Themes Emerge In Social Media Posts?, Gabby C. Scalzo

Theses and Dissertations

Compared to the amount of research conducted on how to identify and understand children with Attention-Deficit Hyperactivity Disorder (ADHD), there has been relatively little work done to understand the lived experiences of adults with ADHD. Increased understanding of how adults with ADHD conceptualize themselves in the context of their diagnosis would help clinical experts tailor research and treatments to better serve these communities. However, there are several barriers towards conducting high-quality qualitative research, including time- and labor-intensity. This study, informed by qualitative research traditions, used innovative data sources (i.e., social media) and analytic techniques (i.e., machine learning) to reduce these …

On The Rebound: Resilience And Subjective Cognitive Symptoms In Cancer, Giuliana V. Zarrella

Theses and Dissertations

Recent studies have shown a strong connection between resilience and subjective cognitive symptoms in clinical populations. However, there is limited understanding of this relationship in cancer survivors, and no studies examine whether resilience training could alleviate subjective cognitive symptoms in these patients. This study examined the relationship between subjective cognitive function and resilience in non-CNS cancer survivors who participated in a resiliency training intervention, at baseline and from pre- to post-intervention, as well as investigated potential influences of change in subjective cognition. Adult cancer survivors (N=275) participated in the Stress Management and Resilience Training-Relaxation Response Resilience Program (SMART-3RP) …

Sense Make Before Book, Bradley Sinanan

Theses and Dissertations

“Sense Make Before Book” is an Indo-Caribbean turn of phrase which refers to common sense being more important than book smarts. My sister sent me a post the other day on Instagram of an Trinidadian woman using this phrase, saying it was one of Indo-Caribbean origin. I was interested and asked my mom about it. My mom says that when she was younger my grandpa said it often around their house in Princes Town, Trinidad and Tobago. This adage feels charged thinking about the history of indenture and its effects on the Indo-Caribbean diaspora.

The written word of archival history …

Obesity Knowledge And Bmi In Caregiver-Adolescent Dyads: A Descriptive Comparative Pilot Study, John Sykes, John Sykes

Theses and Dissertations

Abstract

Background: The prevalence of obesity and associated health risks and costs continue to increase. The majority of these health and cost ramifications manifest in adulthood, making it imperative to intercept the problem during childhood. Unfortunately, an overwhelming majority of the research surrounding adolescents and obesity to date involves subjects that are already overweight or obese, and the focus of those interventions are on secondary and tertiary prevention. Focusing on primary prevention of childhood obesity could ultimately decrease the incidence, prevalence, and disease-related burden to society. It is posited that the 20% difference in obesity prevalence between adults and children …

A Walk In The Woods, Caitlin Mclean

Theses and Dissertations

A connection with nature fosters increased appreciation, admiration, and responsibility toward the natural environment, thus encouraging the mindful use of its resources and preservation of both species and their habitats. Defined by Mayer and Frantz (2004) as an “experiential sense of oneness with the natural world”, this connection is more important now than ever in this highly digital era. Studies indicate that limited exposure to nature can negatively impact the activation of neural pathways associated with pro-environmental attitudes and behaviors (Chawla, 2020), while further research shows that engagement with the outdoors during childhood as a significant life experience (Chawla, 1998), …

Elucidation Of The Optical Properties Of Si And Si-Ge Alloy Nanostructures With Visible To Near-Ir Photoluminescence, Griffin Spence

Theses and Dissertations

Silicon and silicon-germanium alloy nanostructures have garnered increasing attention in the past 25 years due to their favorable optical properties, visible to near-IR luminescence, and inherently low toxicity. While many synthetic routes have been discussed in the literature, the high-temperature, solid-state disproportionation of hydrogen silsesquioxane (HSQ) has become the most popular way to produce highly crystalline, size-tunable Si and Si-based nanostructures (NCs). It has been shown in this work that maximum annealing temperature from 450°-1100°C and the addition of GeI₂or SnCl₄ precursors can be used to achieve different morphologies, alloying efficiency, and sizes. Directly annealing HSQ from …

"I Call Them Supermoms": Therapists' Reflections On The Impact Of Youth Sexual Offending On Latina Mothers, Mauricio P. Yabar

Theses and Dissertations

Families of youth who have sexually offended often suffer significant collateral consequences following the discovery of the sexual offense. Samples in research with these families disproportionately consist of mothers and other female parental figures. This is rarely acknowledged in the literature, and the experiences of these mothers have not been explicitly examined. In addition, research on the experiences of these families has largely ignored factors related to race and ethnicity. This is a significant oversight considering the prevalence of systemic racism and discrimination in the United States, particularly in the systems with which these families must interact (e.g., juvenile justice …
