Beyond Single Metrics: A Holistic Benchmarking Framework For Low-Power Embedded Systems, Hassan Adam

UNLV Theses, Dissertations, Professional Papers, and Capstones

Modern embedded systems encounter a notable challenge in evaluation. While devices may meet traditional benchmarks, they often underperform in real-world applications due to neglected interactions at the system level. Current benchmarking suites, such as MLPerf Tiny and EEMBC ULPMark, evaluate specific metrics including computational throughput, energy efficiency, and memory usage. However, they do not consider the complex interdependencies that affect real-world performance. This thesis presents a benchmarking framework that concurrently evaluates multiple performance dimensions under realistic workloads, revealing system behaviors that are often hidden in conventional benchmarks.Through the comprehensive evaluation of three representative algorithms: Fast Fourier Transform, quantized neural network …

Effects Of Body Armor On Respiratory Muscle Fatigue And Muscle Blood Flow During Progressive Treadmill Marching, Kathryn Bell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Torso-borne loads such as body armor are essential for modern military operations but impose mechanical and metabolic strain. These physiological stressors can trigger the inspiratory metaboreflex, which redirects blood flow from locomotor to respiratory muscles, further reducing muscle oxygen and endurance. While aerobic fitness has been shown to alleviate these effects, the interaction between sex, aerobic capacity, and oxygenation under load is not well understood. This study examined the physiological effects of torso-borne load carriage on respiratory muscle fatigue, skeletal muscle oxygenation, and exercise performance to volitional exhaustion and the degree to which sex and aerobic capacity influence these …

Morphological And Transcriptional Responses Of Mammalian Cells To Glucose Stress, Cassandra Burke

UNLV Theses, Dissertations, Professional Papers, and Capstones

Organismal cells encounter varying conditions, including daily and potentially seasonal fluctuations in available glucose. While some species tightly regulate circulating glucose levels, others tolerate extreme fluctuations, such as frugivorous bats experiencing post-prandial hyperglycemia and hibernating mammals maintaining stable glucose through torpor and hibernation. To investigate how these species-specific strategies influence cellular responses to glucose perturbation, primary dermal fibroblasts from nine mammals – humans, rats, Egyptian fruit bats, brown bear, 13-lined ground squirrel, little brown bat, gelada, honey badger, and Bactrian camel – were exposed to hypoglycemic (2.5mM), baseline (8mM), or hyperglycemic (30mM) treatment. Cell morphology was evaluated using Cell Painting, …

An Examination Of The Purity Culture Beliefs Scale And The Interaction Of Religiosity, Purity Culture Beliefs, And Pornography Use In A Census-Matched United States Sample, Kaelyn R. Griffin

UNLV Theses, Dissertations, Professional Papers, and Capstones

The impacts of purity culture have been documented in the prevalence of abstinence-only sex education, perception of personal value tied to virginity, and shame and guilt related to sexual behavior. Similarly, models of moral incongruence often examine religiosity as a contributor of distress related to sexual behavior and pornography use, likely tapping into the influence of purity culture without directly naming its presence. This distinction is crucial due to the variety of religious beliefs and practices, some including purity culture and those without sexually restrictive beliefs and practices. Despite this, standardized measures for researching purity culture are limited. Ortiz (2018) …

Understanding Ore Deposit Scale Controls On Au Enrichment In Carlin-Type Au Mineralization: A High-Resolution Study Of The Rita K Deposit, Conner T. Callaway

UNLV Theses, Dissertations, Professional Papers, and Capstones

Controls on the distribution of gold (Au) within the Rita K Carlin-type deposit are poorly understood. The primary Au-bearing carbonate unit Wispy, is a bioturbated muddy limestone with debris flow clasts that range in size but are typically >5 cm occurring in the lower sections. The orebody is described as a syncline-anticline pair that hosts high-grade Au ore in the fold hinges. The spatial relationship between Au mineralization and fold hinges suggests that shortening due to folding is an important mechanism producing Au-enriched zones. However, the exact mechanism of Au enrichment and deposit-scale controls on Au distribution and fluid evolution …

Housewerk: How Drag Performers Engage In Emotional Labor While Navigating Community Care, Steph O. Landeros

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation examines drag performance as a form of service labor shaped by emotional labor, community care, and identity-based inequality. Drawing on interviews with drag performers shows how drag labor blends artistic skill, emotional regulation, interpersonal care, and entrepreneurial labor. While these demands mirror service sector roles in other industries, drag remains underrecognized and undervalued, particularly for performers who do not conform to white, cisgender norms. The study introduces Housewerk—an adaptation of Marlon Bailey’s concept of housework (Bailey, 2013)—to describe the mix of paid and unpaid labor drag performers engage in. Housewerk captures how performers must balance self-preservation (branding, income, …

Mechanisms Of Gold Enrichment In Seafloor Massive Sulfide Deposits: A Study On The Higashi-Aogashima Hydrothermal Field, Claudia Martinez

UNLV Theses, Dissertations, Professional Papers, and Capstones

The study of Seafloor Massive Sulfides (SMS) deposit formation is vital for assessing both the economic potential and environmental risks posed by future marine mining projects. Metal-rich SMS deposits form in hydrothermal vent systems within tectonically active regions, such as back-arc basins, where faults enhance crustal permeability, enabling fluid migration driven by magmatic heat sources at depth in the crust. Currently our understanding of SMS formation processes is based on bulk-rock geochemical and isotopic data, lacking the necessary spatial and temporal resolution to understand ore forming processes. As a result, critical gaps remain in understanding the exact mechanisms responsible for …

Ecological Momentary Assessment Of Mood, Affect, And Perceived Criticism: Investigation Of Daily Patterns And Family Impact, Kayla Mcginty

UNLV Theses, Dissertations, Professional Papers, and Capstones

Perceived criticism (PC) is a component of expressed emotion (EE) that assesses an individual’s perceptions of the criticism that they are exposed to within their interpersonal relationships. PC is elevated among individuals with mood disorders, and mood and mood symptoms act as both a predictor and an outcome of PC. However, few studies have examined the relationship between PC and affect, a more momentary measure of emotion that can serve as a guide to underlying mood. Additionally, limited research has examined how PC within family relationships compares to other interpersonal interactions. Understanding the relationship between momentary affect and PC and …

Error Processing In Psychopathy: An Analysis Of Event Related Brain Potentials And Post-Error Task Behavior, Ananda Liz Peixoto Couto

UNLV Theses, Dissertations, Professional Papers, and Capstones

Performance monitoring and error processing are crucial for learning from mistakes, adjusting responses, and adapting to the environment. Individuals with psychopathy present with failures in performance monitoring, particularly a failure to learn from experience, and error processing deficits have been reported in this population. Error processing literature has investigated its underlying mechanisms via two prongs, namely behavioral measures and electroencephalography (EEG) indicators. Behaviorally, error processing literature has focused on post-error slowing (PES) and post-error accuracy (PEA). Meanwhile, EEG research has identified two components of error-related brain potentials (ERPs) in error processing: error-related negativity (ERN) and error positivity (Pe). This study …

Tractors On The Mall: Unraveling The New Deal, Political Shifts, And The 1980s Farm Crisis, Tracy M. Neblina

UNLV Theses, Dissertations, Professional Papers, and Capstones

In the 1980s, Midwestern farmers faced an economic crisis that rivaled the Great Depression. Agricultural policy in the 1970s and 1980s led to a boom and bust for many of the nation’s farmers, causing the decline in rural communities in the middle of the country. During this period, more efficient agricultural production, shifting federal policy, high inflation, and devalued farmland led farmers in the Midwest to face incredible economic hardships, loss of land, changes in their communities, and challenges to their sense of purpose and identity. The Farm Crisis of the 1980s furnishes an extraordinary opportunity to investigate a confluence …

More Than A Feeling: A Mixed-Methods Examination Of Transgender Community Connectedness And Associations With Suicidality, Erin Rook

UNLV Theses, Dissertations, Professional Papers, and Capstones

Transgender adults experience significantly higher rates of suicidal ideation than the general population. A sense of transgender community connectedness (STCC) may reduce this risk, but predictors of STCC and its association with suicidal ideation are understudied. This cross-sectional mixed methods study examined STCC and past-year suicidal ideation in relation to dimensions of transgender community connectedness (TCC) at each level of the Social Ecological Model using data from a U.S. survey of transgender adults (n = 126). About half (52.4%) felt connected to the transgender community, and 27.0% reported past-year suicidal ideation. Hierarchical logistic regression models for both outcomes showed good …

The Compositional And Dynamical Properties Of Exoplanets, Cody James Shakespeare

UNLV Theses, Dissertations, Professional Papers, and Capstones

The solid surface density profile of protoplanetary discs, and the composition of these solids, can be formed through sequential condensation models of dust precipitating from the cooling gas of the solar nebula. I continue developing a code that reproduces the chemical compositions of most chondrites as well as the bulk compositions of the rocky planets using our partial condensation model with an evolving disc. I extend this validated code to exoplanet systems with different initial elemental ratios, like the carbon-to-oxygen ratio and estimated stellar abundances over the age of the universe. I have improved this dust condensation code to include …

School Absenteeism In Children With Disabilities: An Analysis Of School Climate And Academic Mindset, Karolyne Bastos Stucki

UNLV Theses, Dissertations, Professional Papers, and Capstones

Students with disabilities (SWDs) are more likely to be chronically absent than general education peers (Anderson, 2021; Gee, 2018, U.S. Department of Education, 2016). Etiology for SWDs is complex with influencing factors spanning multiple ecological levels, but bolstering protective factors for SWDs may address attendance disparities. Multi-tiered systems of support (MTSS) models have the potential to address absenteeism in SWDs via school-wide preventative and/or intervention efforts (Tier 1 & 2) aimed at increasing or decreasing influencing factors in students with disabilities. School climate and academic mindset may influence students with disabilities’ attendance. The purpose of the present study was to …

An Analysis Of The Influence Of Human Disease Pathogens On Core Behaviors Of The Black-Legged Tick, Emily F. Marinko

UNLV Theses, Dissertations, Professional Papers, and Capstones

Ixodes scapularis, the black-legged or deer tick, is a vector for several different disease-causing microbes, including the causative agent of Lyme disease. As such, it is a major health concern for people living within its range in the eastern half of the United States, a habitation area that is increasing due to climate change. Despite its medical relevance as a disease vector, there is still much to learn about the basic behavior of these arachnids in the wild. Thus, the major hypothesis of this thesis is that ticks that are infected with specific human disease-causing microbes behave differently than those …
