Estimation Of Spo2 Levels And Heart Rate From Ppg Signals In The Presence Of Motion Artifacts, Chizhong Wang

Dissertations

In the rapidly advancing world of health technology, wearable devices are at the forefront, fundamentally changing how individuals monitor their health. The key to this transformation is photoplethysmography (PPG), a non-invasive optical method that measures blood flow variations through the skin by detecting changes in light absorption with each heartbeat. This capability makes PPG essential for monitoring vital signs such as heart rate and blood oxygen saturation(SpO₂). Furthermore, the utility of PPG signals has been extended beyond traditional health metrics to include human activity classification, offering a holistic perspective on an individual's physical health and activity levels, in …

Identity Development In Black Caribbeans: A Proposed Model, Shenelle Frederick

Dissertations

The paper is a critical review of the literature exploring factors contributing to Black Caribbean identity development. The paper sought to understand Black Caribbeans’ migratory history, views on mental health, and factors contributing to their identity development in the United States. Migrating to the United States can be a harsh reality for many migrants because they eventually realize that their Black skin is associated with negativity. An exploration of Black Caribbeans’ history and growing up in predominately Black societies could provide some insight that contributes to some of their ideologies and beliefs regarding forms of racism and believing that hard …

This study answered the following research questions: Q1 What are the acculturation experiences of post-9/11 student …

Influence Of Social Capital On Community-Based Health Care Programs In Rural Paupa New Guinea: An Ethnographic Study, Carol J. Bett

Dissertations

This descriptive, ethnographic study explored the influence of cultural health beliefs and social capital on the adoption of community-based health care interventions by rural villages in Papua New Guinea. The development of local level resources that lead to improved health indices requires an awareness of both the cultural context and the relational components of social capital that link people within the community. Social capital has been defined as resources that are an inherent part of a social group and the elements of social organization such as trust, networks, and norms of reciprocity that facilitate mutual cooperation (Billings, 2000; Carpiano, 2006). …

Interaction Of Particles With Plasma And Shock Produced By Pulsed Spark Discharge, Shomik Mukhopadhyay

Dissertations

Interactions of powders with high-temperature plasma and shockwaves occur in diverse scenarios, such as nuclear blasts, accidental industrial dust explosions, solid propellant combustion in explosive charges and when removing contaminants from surfaces. Electrostatic Discharge (ESD), known for generating shock and plasma, is a promising lab-scale technique for simulating these interactions. Studies with ESD involved placing powders near a spark-producing gap between electrodes and observing mechanical and chemical processes like particle motion and ignition. A limited range of spark conditions and material properties have been tested, which facilitated the development and validation of preliminary computational models describing this system. Significant gaps …

Molecular-To-Continuum Scale Modeling Of Aerosols: Atmospheric Application And Beyond, Ella Ivanova

Dissertations

Aerosol modeling is critical for various applications, such as climate forecasting, air quality, and human health impact assessment. During their lifetime, aerosols undergo a complex evolution, usually divided into several stages — formation, processing, transport, and removal — that occur on different scales. Thus, the choice of modeling methods depends on the stage considered. For example, certain stages of particle formation may require nano-scale modeling while aerosol-cloud interactions span from microscale to mesoscale. This study examines the modeling of aerosol behavior over a wide range of scales, from nano to microscale, with implications to mesoscale.

This dissertation presents the anti-fascist Critical Participatory Action Research (CPAR) process of three doctoral student participants/co-researchers, all practicing educators, with varied experiences in public and private education at the middle school, high school, and collegiate level. This research examines the convergence of the participants/co-researchers in response to their shared concerns about ascendent authoritarianism and rising repression and the subsequent formation of this study’s in-process CPAR research collective organized to critically counter, rather than reiterate, this repression.

Enacting the theoretical/methodological frameworks of Critical Theory and Habermas’s Theory of Communicative Action, the participants/co-researchers dialogically determined contemporary fascism to be the focus of …

Islamophobia In Public Schools: A Mixed Methods Look At The Effectiveness Of Parental Ethnic-Racial Strategies In Promoting Resilience Among Muslim Children, Lallia Allali

Dissertations

The ongoing Islamophobic ideology in the United States has magnified discriminatory practices, exclusion, and increased violence toward Muslims (Esposito & Kalin, 2011; Trudo, 2021), and Islamophobia has further disadvantaged Muslim American adolescents through various forms of discrimination against them in schools. In fact, Muslim American students report the highest rate of discrimination across all religious groups, and researchers have found that active family ethnic-racial socialization can often mitigate the negative impacts of discrimination (Hughes et al., 2006; Hughly et al., 2019).

To test this hypothesis, this study was designed to focus on Muslim families’ ethnic-racial socialization practices and the implications …

Evil, Ontology, And Scripture: A Diachronic Analysis Of Augustine Of Hippo's Privatio Boni Concept, Jamie G. Boucher

Dissertations

Augustine of Hippo’s Privatio Boni concept—the idea that evil is not a substance, but the privation of good in a substance—is the most influential early systematic theodical attempt within Christianity to exculpate a good God from responsibility for evil. By approaching Privatio Boni as the intricate interplay of Augustine’s views on evil, ontology, and Scripture, this dissertation aims to clarify misunderstandings surrounding the concept and determine if there is biblical warrant for it. Chapter 1 addresses issues of background, problem, purpose, and justification before introducing a delimited three-staged methodology of establishing context, engaging in diachronic analysis, and conducting a comparative …

Environments Of War: The Pacific Northwest And The Waging Of World War Ii, Katherine L. Macica

Dissertations

The Pacific Northwest served an essential role in America’s “Arsenal of Democracy.” Weapons and material produced in the Northwest proved essential to the Allied victory in World War II. These weapons served as agents of destruction abroad, but became agents of transformation for the places in which they were produced. This dissertation examines four of the most important resources and industries in Oregon and Washington to emerge or expand as a result of the war: hydroelectric power, forest products, shipbuilding, and aircraft manufacture. The wartime development of these industries profoundly reshaped the physical and economic landscape of the Pacific Northwest, …

Sensing The Rhizosphere: Microbial Transcriptome Responses To Root Exudates And Redox-Active Metabolites, Ankita Bhattacharyya

Dissertations

The term “rhizosphere” describes the dynamic interface between plant roots and soil influenced by root exudates. It is a hotspot of microbial activity, plant-microbe, and microbe-microbe interactions. Distinct variations in bacterial diversity are thought to be driven by plant root exudates. However, the molecular details of these processes still remain unclear.

I addressed this gap by focusing on two strains, Pseudomonas synxantha 2-79 and Burkholderia lata 383, representing diverse groups of Gammaproteobacteria comprised of species with environmental, agricultural, and medical significance. In the first part of this project, we used a combination of metabolomics and RNA-seq to characterize transcriptome responses …

“‘State Of War’: British Racial Construction, New World Slavery & The Impact Of Somerset’S Case In The Anglo-American Diaspora", John David Kemp

Dissertations

On Monday 22 June 1772, the English jurist William Murray, 1st Earl of Mansfield, delivered his oral verdict as Chief Justice of the Court of King’s Bench in the famous case involving the enslaved Afro-British servant James Somerset to declare that only an Act of Parliament could legalize domestic bondage and that Somerset was a free man. For the estimated 15,000 captives living in the English metropole, Somerset v. Stewart effectively undercut the Anglo-Atlantic slavocracy that had hid behind legal technicalities and extrajudicial decrees defending domestic bondage since the last quarter of the seventeenth century. In order to offer a …

Motion-Resistant Pulse Oximetry, Ludvik Alkhoury

Dissertations

The measurement of vital signs ? such as peripheral capillary oxygen saturation (SpO₂) and heart rate (HR) levels ? by a pulse oximeter is studied. The pulse oximeter is a non-invasive device that measures photoplethysmography (PPG) signals and extracts vital signs from them. However, the quality of the PPG signal measured by oximetry sensors is known to deteriorate in the presence of substantial human and sensor movements contributing to the measurement noise. Methods to suppress such noise from PPG signals measured by an oximeter and to calculate the associated vital signs with high accuracy even when the wearer …

Sparse Methods For Blind Source Separation Of Frequency Hopping Rf Sources, Anushreya Ghosh

Dissertations

Blind source separation (BSS) is performed on frequency hopping (FH) sources. These radio frequency (RF) signals are observed by a uniform linear array (ULA) over a Spatial Channel Model (SCM) in four different propagation environments: (i) line-of-sight (LOS), (ii) single-cluster, (iii) multiple-cluster, and (iv) LOS with interference. The sources are spatially sparse, and their activity is intermittent and assumed to follow a hidden Markov model (HMM). BSS is achieved by utilizing direction of arrival (DOA) of the sources and clusters. A sparse detection framework is applied to obtain estimates of the sources' FH and DOA patterns. The solutions are binned …

Temporal Sequence And Relationships Between Sleep Disorders, Mental Disorders And Traumatic Brain Injury In Deployed Military Members, Pamela Herbig Wall

Dissertations

U.S. military members are often forward deployed to austere environments where they are exposed to environmental, mental, and physiological stressors that can negatively affect their wellbeing and readiness for service. These service members are at high risk for developing sleep disorders, mental disorders, and traumatic brain injury (TBI) that may produce functional disability and further erode mission readiness. While there is ample evidence on distinct relationships between these three clusters of disorders, relatively few studies examine all three in a military and/or veteran population. Health care providers in the United States Military need information about these complex interactions in order …

The "Othering" Of America: How The Strategic Use Of Crisis And Ressentiment Succeeded In The Trump Era, Laura J. Franklin

Dissertations

The establishment of a crisis theme through public rhetoric often triggers widespread attention, resulting in public concern and media coverage of an issue that could potentially be overblown or deceptive. In right-wing political discourse, this crisis warning is typically delivered by a White male leader with ready access to the powerful news media. An “us versus them” theme often occurs. Within this mode of a hegemonic exclusion, a culture of immigrants or an American minority are often depicted, perhaps aggressively, as a threat: A threat used to motivate, enrage and create the frustrations inherent in ressentiment. This dissertation explores the …

Dungeons & Dragons & Dewey: Toward A Ludic Pedagogy Of Democratic Civic Life Through The Philosophy Of John Dewey And Tabletop Role-Playing Games, Susan Haarman

Dissertations

In this dissertation, which uses philosophical inquiry, I posit that tabletop role-playing games (RPGs) can provide an educative experience for democratic civic life in the Deweyan tradition. Tabletop RPGs present an invaluable resource for ongoing civic formation by encouraging deliberation and consensus building across shared goals and circumstances. Philosopher John Dewey emphasized that democracy is defined by the civic habits and collective action, not formal governance structures. The experience of playing tabletop RPGs can cultivate habitus and space for future and current citizens to practice democratic skills and commitments. Therefore, these games are a means that align with the ends …

Negative Memory Bias And The Impact Of Early Childhood Stress, Elizabeth Cecile Shmikler

Dissertations

Childhood Trauma is a pervasive problem in the United States, and research suggests it serves as a strong contributor and. Predictor for a multitude of negative mental and physical health disorders (Vrijsen et al., 2018). Negative memory bias, a neuropsychological precursor to later onset of adult mental health disorders, has been scientifically related to childhood trauma (Pollak et al., 1998). Despite numerous findings supporting the relationship between negative memory bias, childhood trauma, and mental health, little is known regarding the age of onset of negative memory bias (Brainerd & Reyna, 2012; Kujawa et al., 2011). Given the research supporting the …

The Expansionist Cause: Union Civil War Commemorations As Weapons Of Colonization In The American West, Lindsey Peterson

Dissertations

Eastern collective remembrances of the American Civil War have dominated discussions of the war’s causes and consequences. The West was located far from major Civil War battlefields and historic sites and therefore deemed peripheral to the war and its legacy. Consequently, historians’ eastern-focused arguments about the war’s historical memory have largely been applied to account for all Union veterans and their families’ experiences, even though the evidence is grounded predominantly in source materials from east of the Mississippi River. Using analytical methods of gender and race, The Expansionist Cause examines Union Civil War commemoration in the trans-Mississippi West to argue …

Relationships Between Monomer Chemical Structure, Network Architecture And Thermal Stability In Glassy Polycyanurates, Rebecca Haber

Dissertations

We study monomer melt properties and polymer properties using two approaches. The first approach takes advantage of molecular dynamics to calculate monomer melt properties. The second approach involved an experimental investigation of polycyanurate networks with varying monomer functionality and rigidity.

For our computational study we applied an existing voids method by Solca et al. to calculate melting temperature for four different cyanate esters: (a) 2’-(4-cyanatophenyl) propane (BADCy), (b) 4,4'-(ethane-1,1-diyl) bis(cyanatobenzene) (LECy), (c) tris(4-cyantophenyl) methylsilane (SiCy-3), and (d) bis(4-cyanatophenyl) dimethylsilane (SiMCy). For systems with 1 to 10% voids, the predicted melting temperature decreased due to a decrease in the free energy …
