Dynamic Inductive Power Transfer Systems With Reflexive Tuning Networks Designed By Machine Learning, Shuntaro Inoue

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation proposes a new way to make dynamic wireless charging systems more affordable. Instead of using one inverter for each transmitter coil, as is typically done, the proposed system uses a single inverter that is connected to multiple transmitter coils. This approach is made possible by reflexive tuning, which allows for high currents to be achieved only on the transmitter coil in use. The system was tested with a 50kW prototype, designed using a combination of neural networks and genetic algorithms. The prototype was tested on both automated rail and vehicle systems. The measured dc-dc efficiency with single and …

This study explored if patterns of family communication were related to five behaviors that young adults might use to cope (drinking alcohol, watching TV, masturbating, eating, and exercising) via emotion regulation strategies. The data used for this study came from 504 young adults living across the United States who completed an online survey which asked them questions about how their family communicated when they were adolescents, their emotion regulation strategies, and how often they use the five coping behaviors listed above. The participants were between 18 and 30 …

Communication‐Less Synchronous Rectification For In Motion Wireless Charging, Joshua B. Larsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis puts forward a control scheme to allow for synchronous rectification for dynamic wireless power transfer. The automotive industry is transitioning away from internal combustion engines (ICEs) and towards electric vehicles (EVs). This transition is spurred by the environmental and economic benefits EVs offer over ICEs. However, further improvements can still be made to how electric vehicles operate. One of these improvements is the technology of in motion wireless charging or dynamic wireless power transfer. In motion wireless charging offers the ability to remove existing range anxiety concerns for EVs. It also offers the potential for a reduction in …

Generative Neural Network Approach To Designing And Optimizing Dynamic Inductive Power Transfer Systems, Andrew Pond Curtis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Electric vehicles (EVs) offer many improvements over traditional combustion engines including increasing efficiency, while decreasing cost of operation and emissions. There is a need for the development of cheap and efficient charging systems for the future success of EVs. Most EVs currently utilize static plug-in charging systems. An alternative charging method of significant interest is dynamic inductive power transfer systems (DIPT). These systems utilize two coils, one placed in the vehicle and one in the roadway to wirelessly charge the vehicle as it passes over. This method removes the current limitations on EVs where they must stop and statically charge …

Reimagining Culture With Youth: Relationship And Representation In Culturally Centered Learning Environments, Lili Yan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation intends to develop an understanding of how culturally centered learning environments impact youth’s relationship with culture. Working alongside a multicultural team of researchers, educators, and designers who came together with a shared goal of designing curricular activities to engage sixth graders with culture, I followed 12 sixth graders for a school year to understand their development of relationships with culture. I (re)conceptualize the holistic process of learning and engagement with culture as Ti-Wu and propose a cultural learning model that helps us understand how youth develop multiple relationships with culture. I further share how multimedia technology mediates youth’s …

High Efficiency Angles-Only Space-Based Approaches For Geosynchronous Orbit Catalog Maintenance With Sparse Information, Louis M. Tonc

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The thesis of this dissertation proposes a novel filter algorithm to improve tracking and catalog maintenance of uncooperative satellites and other Resident Space Objects (RSOs) in Geosynchronous Equatorial Orbit (GEO). Tracking can be supported by space-based tracking from observer satellites (OBSs). Practical limitations can lead to long time gaps between measurement updates when tracking RSOs from an OBS, which may induce a loss of fidelity or divergence of the estimation algorithm. The Extended Kalman filter (EKF) is commonly used for tracking RSOs but it diverges as a consequence of nonlinearity in the dynamics and nonlinearity in the optical measurements from …

The state of democracy facing expanding political division and pervasive racial and social inequalities. Discussing and deliberating controversial social and political issues functions help foster students' civic contribution. I conducted a qualitative case study and recruited 14 participants, with whom I conducted interviews, self-reflection, observation, and autoethnography. I targeted the primary research question: How do pre-service elementary teachers experience and get influenced by discussing social and public issues? I broke it down to six operational questions:

1. What issues are considered controversial by pre-service teachers in their future social studies classrooms?
2. What challenges do pre-service teachers perceive in controversial issues teaching? …

A Generative Neural Network For Discovering Near Optimaldynamic Inductive Power Transfer Systems, Md Shain Shahid Chowdhury Oni

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An urgent need is to electrify transportation to lower carbon emissions into the atmosphere. Wireless charging makes electrical vehicles (EVs) more convenient and cheaper because energy is transferred to the vehicle without the need to plug it in. Dynamic wireless charging is particularly interesting, where the vehicle does not need to stop to receive the energy. This technology requires the EV and the roadway to include coils of wire, where the roadway coil is energized as the vehicle passes over it to induce an electrical current in the EV coil through electromagnetic induction. However, the problem of designing the two …

Two surveys were developed and sent out to instructors and consumers aligned with the research objectives designed to collect information on instructors’ self- perception of self-efficacy after certifying their perceived barriers to receiving certification, and consumers’ selection criteria for instructors. The average certified instructor was extremely satisfied with their decision to pursue …

Fractally Sampling Diversity-Environment Relationships To Understand Plant Assemblage Health Across Spatial Scales, Elizabeth G. Simpson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Humans influence the health of ecosystems and rely on healthy ecosystems to support their livelihoods and well-being. By looking at how the parts of ecosystems interact we can understand and improve ecosystem health. Ecosystem interactions change across spatial scales or different size patches of area. For example, individual organisms interact with each other at small spatial scales, while at large spatial scales, communities of organisms interact with weather conditions. However, many research studies do not look at how ecosystem interactions change across spatial scales. To address this gap in ecological research, I use a fractal sampling design which samples at …

We Travel Together: Examining The Drivers And Functions Of Animal Movement In Biotic Seed Dispersal, Binod Borah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plants and frugivorous animals exist in mutually beneficial relations, as these animals feed on fruits, ingest the seeds, and carry them away from the parent trees. Such dispersion of seeds over space helps them colonize new habitats, escape high mortality rates near their parent trees, and avoid competition with conspecifics. Therefore, seed dispersing animal movement can be critical for the persistence of plant populations. Yet what drives such seed disperser movement is often less understood and how it affects seed dispersal is little explored. In my dissertation, I investigate multiple drivers of seed disperser movement, link movement to potential seed …

Student Perceptions Of Male And Female Instructors In A Post-Secondary Welding Course, S. Kjersti R. Decker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Agricultural mechanics and welding have traditionally been perceived to be careers reserved for males, yet more females have entered professions using welding such as agricultural education. This research was developed because of the lack of gender research in welding. The purpose of this study was to examine students’ perceptions of learning from a male instructor versus a female instructor in a post-secondary welding course. We examined associations and differences between students’ preference of a male and a female welding instructor as well as individual self-efficacy and perceptions towards using welding technology. The population for this study was undergraduate students and …

Teachers’ Learning Of Fraction Division With Area Models, Michael Leitch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research shows that fractions concepts play an essential role in the learning of later mathematics. However, fractions are notoriously difficult to learn and difficult to teach. Division with fractions is a frequent subject in mathematics education research because division is the most conceptually difficult of the four basic arithmetic operations and rational numbers are the most conceptually difficult numbers in K-12 mathematics curricula.

In the U.S., teachers are generally proficient with mathematical procedures, but often have difficulty explaining the concepts underlying the procedures. Research indicates a positive association between student learning and teachers’ depth of conceptual understanding of mathematics. Thus, …

Evaluating Methods For Pathogen Spillover Detection And Forecasting In Desert Bighorn Sheep (Ovis Canadensis Nelsoni), Grete E. Wilson-Henjum

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Managers mitigate the effects of disease on wildlife populations by detecting outbreaks and predicting disease transmission. Bighorn sheep (Ovis canadensis) populations face threat from the introduced pathogen Mycoplasma ovipneumoniae (M. ovipneumoniae). In the eastern Mojave Desert, managers detect pathogen outbreaks in desert bighorn (O. c. nelsoni) through aerial population surveys, which produce irregular and coarse population information. Furthermore, managers model the risk of M. ovipneumoniae transmission amongst desert bighorn populations, however these models assume that desert bighorn space use is unchanging across years. Here, I evaluate methods used by managers to detect disease outbreaks …

Tacitus, Barditus, And Odin's Eleventh Spell, Marie Skinner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Roman Historian Cornelius Tacitus wrote about native Europeans in 98 C.E., around a thousand years before the same peoples began recording their own history. Despite this, the work titled Germania is little-known and under-utilized. It is only by studying Germania and discussing it that the text will be seen for what it is and neither dismissed nor taken out of context. This thesis examines a few of the many passages of Germania that correspond with archaeological, literary, legal, and artistic information from later periods, demonstrating the value of Tacitus’ work to anyone studying European history.

Toward A More Holistic Understanding Of Uranium-Related Views And Experiences Of Residents In The Four Corners Region Of The United States, Matthew J. Barnett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research on rural Four Corners Region (FCR) residents’ views about uranium production has focused mainly on predominately-White communities in the northern portion of the region. Meanwhile, residents in the southern part of the region, which includes the Navajo Nation and other tribal nations and communities, have dealt with the worst environmental and health effects of the uranium boom. Through a series of three studies in the southern part of the FCR, I explore the uranium-related views and experiences of racially diverse FCR residents.

In the first paper of this dissertation, I used 53 interviews to explore how sociodemographic factors (e.g., …

Mediated Cheap Talk With An Uncertain-Biased Expert, Xianzheng Sun

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

When bridging between experts and audiences, media firms often have their own biases which give them the incentive to manipulate information deliveries. This paper studies a cheap talk game in which media firms(moderators) can strategically design the delivery of experts’ messages to decision makers. A moderator is allowed to affect the delivery of messages by selecting experts and informing the decision-maker about the experts’ biases. I show that moderators can in equilibrium send partition-type messages to inform the receiver of experts’ biases, and moderation can improve communication informativeness.

Photonic neural networks are designed using brain-Rabi antenna communication, and transmissions are connected via neurons. Communication signals are carried by electron spin (up and down) and adjustable Rabi frequency. Hidden variables and deep brain signals can be obtained by external detection. A Rabi antenna has been developed by simulation using computer simulation technology (CST) software. Additionally, a communication device …

Inferring Evolutionary Trajectories From Cross-Sectional Transcriptomic Data To Mirror Lung Adenocarcinoma Progression, Kexin Huang, Yun Zhang, Haoran Gong, Zhengzheng Qiao, Tiangang Wang, Weiling Zhao, Liyu Huang, Xiaobo Zhou

Faculty, Staff and Student Publications

Lung adenocarcinoma (LUAD) is a deadly tumor with dynamic evolutionary process. Although much endeavors have been made in identifying the temporal patterns of cancer progression, it remains challenging to infer and interpret the molecular alterations associated with cancer development and progression. To this end, we developed a computational approach to infer the progression trajectory based on cross-sectional transcriptomic data. Analysis of the LUAD data using our approach revealed a linear trajectory with three different branches for malignant progression, and the results showed consistency in three independent cohorts. We used the progression model to elucidate the potential molecular events in LUAD …

Power, Pleasure, And Privilege: Defining Depauw’S Hookup Culture And Its Mental Health Implications, Reanna Stiehler '23

Honor Scholar Theses

Hookup culture is not primarily about sex, pleasure, connection, or freedom. Hookup culture is about power—how power is used, distributed, and desired. Previous work in hookup culture discusses a discourse of desire; however, the root and nature of this desire are unclear. I posit that hookup culture, as it currently exists, is strongly related to rape culture. In this thesis, I will explicate my anecdotal, qualitative, and quantitative evidence supporting this hypothesis.

Synthetic Or Not: Implications Of Hormonal Birth Control On Women’S Hormones And The Cortisol Stress Response, Maddie Perry '23

Honor Scholar Theses

Women’s bodies are the subject of decision-making and control, yet women’s lives are dismally ignored. The field of women’s health is highly understudied, and the demand for that adequate research must be granted to the women’s health field. This interdisciplinary research study investigated stress response differences between hormonal birth control users and non-users. Hormonal birth control (HBC) is one of the greatest technologies afforded to women and further research is necessary to ensure women are guaranteed bodily autonomy and women’s health education. Due to altered hormonal signaling, HBC has been linked to behavioral and decision making differences in women. Building …
