Alvar Aalto: Past. Present.Future, Matthew Collins

Interior Design Capstones

Alvar Aalto serves as a timeless guide for architectural and design principles. These principles are not of universal rigidness but are flexible based on the givenconditions of site, culture, and people. His traditionalmethods of sketching and drawing create a hand to mind connection to the design process. This process, much like his work, develops a mindful and thoughtful outcome of decisions. With computer technology become more increasingly apart of our lives, it is important that we not forget the human point of view rather than purely a rational mode of thinking. This capstone project address how it is possible to …

Estimating Climate Risk In Financial Markets, Olanrewaju Oluwadamilare Olaniyan

Masters Theses

The growing impact of climate change on financial markets necessitates a rigorous approach to climate risk assessment. This thesis examines methods for quantifying climate-related financial risks, with a focus on distinguishing climate risk from broader market movements (represented by S&P 500). Using a factor model, we isolate climate risk factors to better understand sector-specific volatility. The insurance sector is used as a proxy for climate risk exposure, given its sensitivity to climate-related losses and regulatory changes. We apply Extreme Value Theory (EVT); the Block Maxima Method and the Peaks Over Threshold Method, to identify excess risk patterns in financial portfolios. …

Experimental Evaluation Of Friedel’S Salt For Chloride Removal In Road Salt-Impacted Stormwater And Lakes, Marwan Alhinaai

Masters Theses

Road salt (e.g., NaCl) application in cold-temperature regions has increased Cl- concentrations in freshwater. Removing Cl- from water is challenging because it’s highly soluble. This paper is the first to demonstrate and characterize the removal of Cl- from stormwater by Friedel’s salt (Ca4Al2(OH)12Cl2(H2O)4) precipitation (FSP), achieved by adding calcium oxide (CaO) and sodium aluminate (NaAlO2). Laboratory tests were done on Cl- removal with FSP using a range of Ca/Al/Cl ratios in deionized (DI) water and in stormwater samples impacted by road salt. Even the lowest doses resulted in significant removal of Cl- with maximum removal rates for comparable Ca/Al/Cl ratios …

Nonparametric Finite Mixture Of Ising Graphical Models, Manal Hamadi Alloqmani

Dissertations

Statistical applications in fields such as bioinformatics, genomics, speech processing, image processing, and communications often involve large-scale models in which thousands or millions of random variables are linked in complex ways. Graphical models provide a general methodology for approaching these problems, and indeed many of the models developed by researchers in these applied fields are instances of the general graphical model formalism. This formalism gives a nice framework for capturing complex dependencies among the random variables and building a large-scale model for high-dimensional data. Recently, high-dimensional data are more assumed to come from one population and follow a parametric or …

Resilient Learning For Anomaly Detection In Smart Living Systems, Sahar Abedzadeh

Dissertations

Cyber-Physical Systems (CPS) rely on anomaly-based detection methods to ensure the integrity and security of critical infrastructures such as smart grids, smart water metering systems, and advanced metering infrastructures (AMI). Anomaly detection methods are commonly used to identify deviations from normal system behavior by establishing learned profiles and thresholdbased distinctions between benign and anomalous events. However, conventional frameworks often fail to account for adversarial data poisoning attacks, unlabeled unsafe events, and environmental noise—factors that distort training data, degrade detection accuracy, and increase false alarms. This dissertation proposes a resilient learning framework that mitigates these biases by integrating quantile regression, M-estimation …

Utilizing Drainage Induced Pfas Enrichment In Cascade Generated Foam For Efficient Removal At Wastewater Treatment Plants, Ethan Samuel Coffin

Dissertations

Observed trends in municipal solid waste landfills reveal a distinct disparity between per- and polyfluorinated alkyl substances (PFAS) composition entering in waste, mostly as diPAP and FTOH, and leaching out as FTCA and PFCA. These patterns are elucidated by compiling PFAS compositions in paper, textiles, and carpet, with known precursor transformations that generate FTCA and PFCA in leachate. Landfill leachate is commonly discharged to wastewater treatment plants (WWTP), which are ineffective at degrading PFAS and only serve as key conduits and discharge points for PFAS to the environment. Foam fractionation has been identified as a promising technology for concentrating and …

Turbulence And Energetic Ion Production In The Partially Magnetized Hollow Cathode Plume, Margaret Mary Mooney

Dissertations

Hall effect thrusters (HETs) are the most widely used electric propulsion (EP) device for in-space satellite propulsion. EP devices provide high efficiencies for extended mission lifetimes and low thrust for precision maneuvers. The hollow cathode is a critical HET component and undergoes extensive lifetime testing in addition to the lifetime testing of the full HET. Significant density gradients, non-Maxwellian electron behavior, and magnetic fields sufficiently strong enough to magnetize electrons in hollow cathode plumes create favorable conditions for the formation of plasma instabilities, which have an impact on cathode lifetime. Cathode qualification testing is typically conducted independently and includes a …

The Ebony Edge: A Qualitative Exploration Of Math Success Among Black College Women, April Ruiz

Dissertations

Historically, women have been underrepresented as leaders in STEM. However, according to the National Science Foundation (2022), women accounted for a little more than half of the college-educated workforce and underrepresented minority women increased in broad science and engineering occupational categories. This promising upturn underscores the importance—if progress is to continue—of better understanding why some African American women succeed in and persist with their study of college mathematics.

This study aimed to explore the experiences of Black college women attending a predominantly White institution in the Midwest, to better understand what reasons Black college women ascribe to their success in …

A Multiple Case Study Of Four-Year Public, Non-Flagship Universities: Meeting Common Institutional Goals Of Increased Enrollment And Academic Profile, Alicia Kornowa

Dissertations

For several reasons, the number of students seeking and enrolling in a postsecondary education has started to decline in the United States (U.S.) and the decrease is expected to intensify for the foreseeable future. This trend is cause for concern among higher education enrollment leaders, especially those who serve at institutions not among the most elite universities or without a national brand—the campuses researchers project will have the greatest difficulty maintaining enrollment levels. Using strategic enrollment management (SEM) as an example of general systems theory and systems thinking, this multiple case study explored how four public, four-year, non-flagship institutions increased …

Moderating Effect Of Fantasy Football Participation And Location On Team Identification And Nfl Fandom, Devon Hudson

Masters Theses

This study explores how fantasy football participation in varying geographic proximities to NFL teams has altered traditional fan allegiances (i.e. team loyalty or fandom) as an alternate consumer product for the game of football. After utilizing survey data to quantify concepts of fandom and team identification amongst respondents, respondent groups were sorted into various groups based on both fantasy participation and location relevant to NFL teams. A series of hypotheses describing relationships between proximity, fantasy football participation, and fan perceptions are analyzed using a series of statistical tests. No statistical significance was found when comparing strength of team identification amongst …

Ready, Set, No: Why Not All Successful Dual Credit High School Graduates Matriculate To Postsecondary Education, Jessica Deckard Mann

Dissertations

Dual-credit programs that allow students to earn college credentials in high school have become commonplace in the United States. Early College High Schools (ECHSs) were specifically developed to support equitable access to these programs, targeting groups that are historically underpopulated in postsecondary education (PSE). ECHSs aim to close the achievement gap, increase the number of college credentials earned by high school students, better train the workforce, and improve the life-time earnings potential of a diverse population.

The purpose of this nonexperimental quantitative study was to gather data from graduates in one Midwestern state who earned a college credential in high …

Upper-Level Undergraduate Pre-Healthcare Students’ Journeys To Graduation And Health Professional Graduate Programs, Holly L. Sisson

Dissertations

Despite decades of research on undergraduate student retention and persistence, only a handful of researchers, such as Dumke et al. (2018) and Stull et al. (2021), have looked specifically at pre-health students preparing for graduate health professional programs and the complex challenges these students face while trying to achieve their goals. Very little research focused on upper-level undergraduate students pursuing graduate health professional programs, such as physical therapy, occupational therapy, physician assistant, or similar graduate health professional programs excluding medical school. To help fill this gap, my study focused on the experiences of pre-healthcare students as they navigated their undergraduate …

An Exploration Of Sensory And Fine Motor-Based Interventions To Address Self-Regulation And School Participation In Students Impacted By The Flint Water Crisis, Katie Sicklesteel

Capstone Projects

To be successful academically, students must first be regulated and ready to learn. For this capstone project, the occupational therapy (OT) process was used to develop and implement sensory and fine motor interventions in a first-grade classroom to support their participation. Given that the target population in Flint has been impacted by the water crisis and poverty, a trauma-informed approach was also integrated throughout. While research shows that OT plays an important role in sensory processing, self-regulation and motor skills in schools, there is a lack of accessible and evidence-based tools for educators to support these areas. To address this …

An Academic Self-Regulation Program For First-Generation Students In Occupational Therapy: A Preexperimental Study, Pola Ham

The Open Journal of Occupational Therapy

First-generation students at U.S. universities have lower academic performance than their continuing-generation counterparts. They also have a lower level of academic self-regulation and academic self-efficacy. Bandura’s social cognition theory and Zimmerman’s self-regulation theory were used as theoretical frameworks to guide an intervention program relating to self-efficacy and self-regulation. A pretest and posttest survey measured changes in the participants’ use of the academic self-regulatory strategies and level of confidence in using those strategies. An open-ended questionnaire provided a detailed account of the participants’ lived experiences of the program. The researcher-facilitator designed an academic self-regulation program using Zimmerman’s (1998) self-regulated learning framework …

Beyond Average Effects In Education Research Syntheses: Explaining Heterogeneity Of Concept Mapping Research In Science Education Through Meta-Regression Modeling, Aaron Wenger

Dissertations

Contemporary education research seeks causal inferences in order to guide policy and practice. Often well-controlled quasi-experimental and experimental designs are used as they are very useful for supporting and contextualizing causal inferences. Nevertheless, individual studies, even high-quality, resource-intensive randomized controlled trials, are not able to establish generalized claims. Because primary studies vary over dozens of variables (e.g., grade, subject, duration) simply conducting additional primary studies cannot change this. Furthermore, the informal assessments of primary studies common in literature reviews are unable to resolve certain challenges (e.g., publication bias) that are described in the emerging field of meta-research. These challenges require …

Faulty Perception Correction Of Autonomous Vehicles In Real-Life Driving Scenarios, Mark Omwansa

Dissertations

Driving is one of the most popular modes of transportation in the world. The United States Department of Transportation’s (USDOT) Federal Highway Administration (FHWA) reported 2.8 trillion vehicle-miles traveled (VMT) in 2020, and the National Highway Traffic Association (NHTSA) recorded 3.2 trillion VMT in 2019. Also recorded in the NHTSA report were 39,096 fatalities and 2.7 million injuries due to traffic accidents, costing the economy an estimated $242 billion. Most of these recorded accidents can be attributed to human error or misjudgment. It is for this reason that governments and the automotive industry are looking at autonomous vehicle (AV) technologies …

Co2 Capture Utilizing Novel Deep Eutectic Solvents: Modeling, Process Simulation, And Cost Analysis, Nazneen Aspi Kolah

Masters Theses

One of the most pressing global issues that humans face is climate change caused by anthropogenic greenhouse gas emissions, especially carbon dioxide (CO2). Conventional solvents utilized for CO₂ capture, such as amines, are widely used in industrial applications due to their high CO2 absorption capacity. However, deep eutectic solvents (DES) have attracted a lot of academic attention recently due to their biodegradability and low energy for regeneration.

This research serves as a foundational proof-of-concept for using DESs in industrial gas separation processes. Five DES are evaluated for CO2 removal from flue gases. Aspen Plus is utilized to simulate the performance …

A Novel Interpretation Of Average Run Length For Assessing The Performance Of Control Charts, Gonçalo Sousa

Masters Theses

The Average Run Length (ARL) is a performance measure of Control Charts widely used within Statistical Process Control. In this study we propose a new approach for the computation of the ARL that is based on a novel interpretation of out-of-control signals produced by a Control Chart. Specifically, out-of-control signals used to calculate traditional ARLs may correspond to Type I errors and may not reflect a Control Chart’s true performance. To compensate for this issue, for Shewhart and EWMA charts, constraints are applied to the calculation of ARLs so that only out-of-control signals that occur when the corresponding statistic is …

Private School Principals’ Leadership Roles In Times Of Change Within The Dominican Republic, Benedicta Calderon

Dissertations

As in many other countries around the globe, the Dominican Republic (DR) has recently implemented important educational changes. The curriculum changed from a content-based to a competence-based approach, and grade configurations changed from four-year to three-year cycles, moving seventh and eighth grades out of elementary and into high school. These changes impacted public and private school structures, with implications on principals’ leadership role. While there is much previous research on principals as instructional leaders implementing significant change; prior to this study, no research was found that looked at private school principals in such roles within a developing country like the …

An Exploration Of The Experiences That Influenced Black Males To Become Information Technology Professionals, Ronnie Mcmillian

Dissertations

Historically, the United States (U.S.) has led the world in the development of innovative high-tech solutions that increased employment opportunities, wages, productivity, and the economic growth of our nation. However, STEM workers are in great need to fill the millions of vacancies in the STEM workforce. Despite the increasing demand for STEM professionals, racial minorities, especially Blacks, continue to be disproportionately underrepresented in STEM. In order to adequately address the STEM workforce problem and remain competitive globally, the U.S. must motivate a much larger cross-section of its population to enter STEM fields. Since Blacks are disproportionately underrepresented in STEM, they …

Computational Modeling In A Calculus-Based Physics Lab: Students’ Problems And Successes In Physics 2060, Abigail Sophia Flowers

Masters Theses

In the past few decades, computational modeling skills have become essential for students who want to pursue careers in physics or engineering. This issue of how to incorporate these skills into students' learning has become an important one because students in these degrees are already required to take several cognates outside of their chosen major. In 2018, Western Michigan University’s physics department decided to take on this issue by reformatting their introductory calculus-based physics labs to include computational modeling within the labs. The labs were first run in the Fall of 2018 and then were improved in spring 2019. When …
