Generalized Model To Enable Zero-Shot Imitation Learning For Versatile Robots, Yongshuai Wu

Master's Theses

The rapid advancement in Deep Learning (DL), especially in Reinforcement Learning (RL) and Imitation Learning (IL), has positioned it as a promising approach for a multitude of autonomous robotic systems. However, the current methodologies are predominantly constrained to singular setups, necessitating substantial data and extensive training periods. Moreover, these methods have exhibited suboptimal performance in tasks requiring long-horizontal maneuvers, such as Radio Frequency Identification (RFID) inventory, where a robot requires thousands of steps to complete.

In this thesis, we address the aforementioned challenges by presenting the Cross-modal Reasoning Model (CMRM), a novel zero-shot Imitation Learning policy, to tackle long-horizontal robotic …

Patterns And Potential Mechanisms Of Phenotypic Changes In Urban Small Mammals, Leslie Lopez

Master's Theses

Urbanization is an example of human induced rapid environmental change that can have wide-reaching ecological effects, including habitat destruction, fragmentation, and alteration of local climates. Effects of urbanization have been shown to impact wildlife, as disturbances resulting from urbanization can create novel environments and selective pressures that could lead to changes in morphology, physiology, or both. Small mammals such as rodents are an ecologically important set of wildlife species because they are a key prey item for several predators, hold strong influence over plants as a primary consumer, and some species carry and transmit major human and animal diseases. Previous …

Role Of Atp-Binding Cassette (Abc) Transporters As A Protector Of Testis Stem Cell Niche From Chemotherapy Drugs In Drosophila Melanogaster, Swagata Maity

Master's Theses

In chemotherapy treatments most tumor cells are destroyed by drugs, but some tumor cells are drug resistant, and these are known as cancer stem cells (CSCs). Normal adult stem cells are also chemo resistant. Therefore, investigation of normal stem cells can be useful to provide further knowledge of CSCs. One of the primary ways that CSCs achieve drug resistance is by drug efflux through transmembrane pumps called ATP-binding cassette (ABC) transporters. Many studies on ABC transporters have been performed in vitro using cultured cell lines, but very few studies have been performed on normal stem cell populations in vivo. Drosophila …

The Unseen Pen: The Hidden History Of Black Women Writers During The Civil Rights Movement, Serenity Hill

Master's Theses

As taught in standard high-school and general educational courses, integration was a primary goal of the Civil Rights Movement; however, when this era is discussed in classrooms, by historians, and in textbooks there are key perspectives and acknowledgements that are less recognized. The visibility of the Black women who pushed forward the movement is often reduced, overlooked, or overshadowed because of the more celebrated contributions of their male counterparts. Focusing on an era before the internet, with the eloquent writing of activists like Dr. King memorialized, this project aims to showcase how changes in course curriculum can shed light on …

See Me Show Me: Black Women Representation In Television Sitcoms, Lauryn Jennings

Master's Theses

Television is a commonplace item within the households of America. It brings the family together as well teaching people about other people. With this Black women have been shown in one-dimensional images that are harmful. Although these stereotypes are old they are still present within modern television sitcoms.

Back To Black: Analyzing The Presence Of White Control Over Black Representations In Media And The Responses Of Black Creators, Serena Smith

Master's Theses

The focus of this thesis largely discusses the perceptions held by White people of Black people and the Black community, and how these discriminatory perceptions have been presented in various forms of consumable media and other societal aspects throughout American history. These racially biased misrepresentations have also negatively affected the progression and internalization of the concept of Black cultural identities for Black people throughout history and how they are able to relate to the rest of American society. I am arguing that contemporary media and films produced by Black creators, such as Cord Jefferson’s 2023 film American Fiction, tend …

"Shut Up and Dribble: The Political Contradictions of Black Masculinity in Sports" is a comprehensive analysis of literature and case studies that explore the regulation and representation of the black masculine body within sports. This thesis investigates three primary themes—sport, protest, and black masculinity—and seeks to uncover the evolution of various black masculine figures and their endeavors toward racial inclusivity. By analyzing sports literature, this work examines the experiences of five significant black athletes, including Jack Johnson, Ron Artest, and Colin Kaepernick, to illustrate how sports environments police the black body. Additionally, this thesis emphasizes two archetypes of black masculinity: …

A Geospatial Analysis Of Patterns In Neighborhood Characteristics And United States Professional Sports Stadium Relocations From 1922-2022, Kara Logan

Master's Theses

In the United States of America, 135 stadiums for new or relocating teams have been constructed between 1970 and 2020 (Bradbury et al., 2022, p. 3). Within those years, researchers, journalists, and community members have examined the impact of those new stadiums on local communities, including economic, environmental, and residential impacts. However, the current scope of literature consists of a considerable number of case studies that examine a single stadium or mega-event, such as the Olympics.

This study will determine what patterns, if any, exist between the demographic and housing characteristics between the stadiums that major league United States professional …

The Role Of B Cell Activation State And Sex In Aryl Hydrocarbon Receptor Mediated Induction Of Chemokine Receptor 9 And Alpha4beta7 Expression In Vitro, Logan Bauerle

Master's Theses

Defense of mucosal tissues from microbial infection and allergy is reliant on continual production of antibodies. The aryl hydrocarbon receptor (AhR) is known to regulate B cell development and is associated with suppression of systemic humoral immunity. Recent attention has been paid to the role of the AhR in altering expression of cell adhesion molecules (CAMs). B cells express CAMs and chemokine receptors to migrate around the body for localized secretion of antibodies. AhR agonists promote B cell migration to the small intestine through upregulation of chemokine receptor 9 (CCR9) and integrin α₄β₇. Both the AhR …

Amid global climate change, exploring adaptive strategies among alpine flora, particularly through clonal growth, becomes critical for biodiversity conservation. This study aims to explore the patterns of dominance and distributions among clonal species across environmental gradients in the Colorado Front Range, employing a trait-based comparative analysis to understand the adaptive strategies of alpine flora and their implications for conservation amid rapid climate change. We focused on two species, studying traits like lateral spread, bud count, and bulbil numbers. Advanced statistical methods such as Permutational Multivariate Analysis of Variance (PerMANOVA) and Multi-Response Permutation Procedures (MRPP) were used to evaluate community compositions …

The Kansas Band’S Musical Depictions Of Spiritual Quests, Elizabeth Romero

Master's Theses

The progressive rock genre has been an intriguing subject of study for the scholarly community, especially within the last 30 years. An understudied part of the progressive rock scene, however, is its manifestation in the United States through the band Kansas. The band from 1970’s Topeka is acknowledged by Mitchell Morris as troublesome for critics due to the hybrid use of European art music and blues influences. It is no wonder a large study of Kansas music has not taken place due to the maligning of the band by its critics as well as the controversial views regarding pretentiousness of …

Diegetic Sonification For Low Vision Gamers, Jhané Dawes

Master's Theses

There are not many games designed for all players that provide accommodations for low vision users. This means that low vision users may not get to engage with the gaming community in the same way as their sighted peers. In this thesis, I explore how diegetic sonification can be used as a tool to support these low vision gamers in the typical gaming environment. I asked low vision players to engage with a prototype game level with two diegetic sonification techniques applied, without the use of their corrective lenses. I found that participants had more enjoyment and experienced less difficulty …

Sustainable Development: What’S The Problem Here? A Post-Structural Discourse Analysis Of The Global Reporting Initiative, Jenniffer Barnett

Master's Theses

The purpose of the study was to critically analyze how the problem of sustainable development is constructed in the Global Reporting Initiative (GRI) and identify what underlying assumptions and historical events produced the problematization as the GRI aims to guide global behavior. The study explored how governing took place by identifying what was silenced in the problem representation and the discursive effects and subject positions it produced. Carol Bacchi's (2009) "What’s the problem represented to be?" (WPR) facilitated this Foucault-influenced poststructural discourse analysis. The interrogation revealed that (a) sustainable development is characterized as a problem of corporate transparency, and (b) …

Building Software At Scale: Understanding Productivity As A Product Of Software Engineering Intrinsic Factors, Gauthier Ingende Wa Boway

Master's Theses

During our education at KSU, we have learned about various factors that affect productivity such as schedule, budget, and risks, but those are often controlled outside of what we could learn as software engineering principles, patterns, or practices. On top of that, other off-work factors such as health conditions, emotional distress, or political climate, just to name a few, could drastically affect the productivity of a software engineering team. We see a demarcation between those factors that affect productivity in software engineering but are not inherent to the discipline itself, which we call resistance factors, and the factors that are …

Kinetic And Kinematic Effect Of Flag-Carrying On Referee Agility And Sprinting Performance, William Reed

Master's Theses

Within competitive soccer, assistant referees are expected to keep up with the top speed of players on the field, despite being hindered mechanically by a flag held down at their side. This ability to keep up with speed-of-play can determine effectiveness of calls on the field, yet while being tested, referees are not required to replicate the game-like state of flag-carrying. The purpose of this study was to examine kinetic and kinematic effects of flag-carrying within sprinting and change-of-direction performance in assistant referees to better inform training programs and testing protocols. 18 male referees (mean age 32.11 ± 9.08 years) …

Does Appearance Matter? The Relationship Of Perceived Body Size And Physical Appearance On Students' Attraction To Physical Activity At Recess, Danielle Belcher

Master's Theses

Drastic declines in recess physical activity (PA) have been observed within recent years (Center for Disease Control (CDC), 2017). Due to recess’ discretionary nature, psychosocial variables associated with PA are predictors of students’ PA levels. Recess is also a time of heightened bullying occurrences (Vaillancourt et al., 2010). Appearance-based bullying is the most common type of victimization that occurs in schools, transpiring more often in children with larger body max indexes (BMI), and possibly altering students’ physical self-perceptions. Physical self-perceptions have been shown to impact PA motivation, however, it is still unknown the extent to which appearance-based bullying, body size, …

Clonal Plants' Traits And Responses Following Fire Disturbance In Ponderosa Pine Ecosystems In The Colorado Front Range, Raymond Erskine

Master's Theses

Mountain ecosystems are currently experiencing increasing impacts of disturbances (e.g., wildfire) due to global changes in climate and land use, leading to significant changes in vegetation composition and landscape dynamics. Clonal plants, characterized by their vegetative reproduction strategies, offer a range of ecologically important traits to cope with disturbances. However, clonality is often excluded in studies of post-fire vegetation dynamics in mountain ecosystems, and our knowledge of the ability of clonal plants to respond to differing disturbance regimes is limited. Therefore, I examined the response of understory vegetation following fire disturbance in burned and unburned ponderosa pine stands of the …

Semantic Segmentation Of Point Cloud Sequences Using Point Transformer V3, Marion Sisk

Master's Theses

Semantic segmentation of point clouds is a basic step for many autonomous systems including automobiles. In autonomous driving systems, LiDAR sensors are frequently used to produce point cloud sequences that allow the system to perceive the environment and navigate safely. Modern machine learning techniques for segmentation have predominately focused on single-scan segmentation, however sequence segmentation has often proven to perform better on common segmentation metrics. Using the popular Semantic KITTI dataset, we show that by providing point cloud sequences to a segmentation pipeline based on Point Transformer v3, we increase the segmentation performance between seven and fifteen percent when compared …

Role Of Toll-Like Receptor 2 In Macrophage Recognition And Response To Borrelia Burgdorferi, Yukiye A. Koide

Master's Theses

Lyme disease is the most common vector-borne disease in the US and will experience an uptick as the insect host, the ixodid tick, gains habitat with climate change. The causative agent of Lyme disease, Borrelia burgdorferi, is recognized by Toll-like receptor 2 (TLR2), which initiates the innate immune response. Here, I used ELISA and SEAP detection assays to determine that knocking out TLR2 in THP-1 macrophages reduces the amount of NFkB activation, as well as IL-10 and IL-1β secretion. Then, I used fluorescence microscopy and Incucyte assays to quantify the amount of phagocytosis performed by wild-type and knock-out THP-1 cells. …

Athletic Identity Association And Prospective Basic Psychological Needs Satisfaction Predict Attitudes Of Collegiate Athletes Toward Seeking Help From The Athletic Department, Allie Zerr

Master's Theses

There is an epidemic of mental health issues that has begun to be more openly talked about in college athletics. In 2022, the National Collegiate Athletic Association has found that college student-athletes are now 1.5-2 times more likely to report struggling with mental health than ever before. Previous research has shown a significant association with basic psychological needs satisfaction and overall psychological well-being. Furthermore, the purpose of this study was to investigate the possible ways that reported of autonomy, competence, and relatedness need satisfaction predicted whether athletes would seek mental health services and identify how athletic identity plays into this …

Species Delimitation Of Slimy Salamanders, Plethodon Kisatchie And Plethodon Mississippi, Across The Lower Mississippi River, Brock Hunter Stevenson

Master's Theses

Species are fundamental units of biodiversity yet delimiting species can be challenging. Slimy Salamanders of the Plethodon glutinosus species complex are a classic example of cryptic species for which species boundaries and relationships have proved difficult to determine. Once thought to be a single species ranging across the eastern United States, protein analysis revealed high genetic divergences among geographically distinct groups of populations, leading to 16 species being recognized within the group. Two of these species, the Louisiana Slimy Salamander (Plethodon kisatchie) and the Mississippi Slimy Salamander (Plethodon mississippi), are closely related but occur on opposite sides of the Mississippi …

Evaluating A Common Book Program's Effect On Gains In Knowledge And Position Toward Sustainability In The Nutrition Professions, Hallie Lanice Shupe

Master's Theses

A Common Reader Program, also called a common book, summer reading, or a one-book program, has been reported to enhance the college educational experience yet appears to have been underutilized by colleges and universities. In the case of health sciences, there can be great benefits in having students learn from the literature not typically found in textbooks used in the curricula. Common reader programs allow for different teaching methods to be implemented and using multiple teaching methods in a single program can be beneficial. In nutrition and dietetics (ND) programs there is a need for additional education regarding sustainability in …

Development Of An In Vitro 3-Dimensional Co-Culture Human Colorectal Cancer Model In Microfluidic Devices, Abby Jens

Master's Theses

Colorectal cancer is the second most common cause of cancer-related deaths in the United States, with the relative 5-year survival rate for distant stage cancer being only 14%. The most common treatment for colorectal cancer is with chemotherapeutic drugs; however, the discovery of these drugs is costly, time-consuming, and often requires the use of animal models that do not yield results that translate to clinical trials. Due to these shortcomings, researchers seek to develop physiologically relevant in vitro tumor models that more accurately mimic the tumor microenvironment for cheaper and faster high-throughput drug screening. The aim of this research was …

As the field of computer security continues to grow, it becomes increasingly important to educate the next generation of security professionals. However, much of the current education landscape primarily focuses on teaching defensive skills. Teaching offensive security, otherwise known as ethical hacking, is an important component in the education of all students who hope to contribute to the field of cybersecurity. Doing so requires a careful consideration of what ethical, legal, and practical issues arise from teaching students skills that can be used to cause harm. In this thesis, we first examine the current state of cybersecurity education in the …

Effects Of Anthropogenic Noise On The Provisioning Behavior Of Western Bluebirds And Artificial Light At Night On Nestling Development, Kerstin H. Ozkan

Master's Theses

Sensory environments are rapidly changing due to increased human activity in urban and non-urban areas alike. For instance, background sounds can interfere with parent-offspring communication and mask cues reflective of predation risk, resulting in elevated vigilance at the cost of provisioning. In chapter 1, we studied nestling provisioning behavior among Western Bluebirds (Sialia mexicana) in response to short-term (1 hr) and long-term (continuous exposure throughout nesting period) noise exposure. Provisioning rates were lower at nests exposed to short-term experimental traffic noise compared to exposure to ambient background sounds. Trial order strongly influenced provisioning behavior, with the decline in …

3d Pano Inpainting: Scene Construction Using A Single Input Panorama, Shivam Asija

Master's Theses

Creating 360-degree 3D content has gained traction in the past few years, being used for Virtual Reality environments. However, creating such content is challenging because it requires a multi-camera setup or a collection of images from different perspectives. This paper proposes 3D Pano Inpainting, a pipeline capable of transforming a single equirectangular panoramic RGBD image into a complete 360° 3D virtual reality scene represented as a textured mesh. Our methodology is as follows: we estimate a consistent depth map for the input panorama; we use a pre built framework to convert the image and its depth map into a textured …

Comparison Of Scanning Electron Microscopy And Confocal Laser Microscopy For Tissue Surface Roughness Characterization, Tarnvir Dhaliwal

It was found that the measurements captured by confocal microscopy and scanning electron microscopy had a statistically significant difference for bovine tissue. There was not a statistically significant for porcine and poultry tissue.

The intent of the study is to perform a comparative study to examine efficacy of two distinct technologies for a singular purpose: tissue surface roughness characterization. The two technologies compared are a confocal reflectance microscope and a scanning electron microscope. The comparison was made by comparing two surface roughness parameters [Ra and Rq] within ImageJ.

The study examined three different animal species [porcine, bovine, and poultry] to …

Finite Element Analysis Of The Bearing Component Of Total Ankle Replacement Implants During The Stance Phase Of Gait, Timothy S. Jain

Master's Theses

Total ankle replacement (TAR) implants are an effective option to restore the range of motion of the ankle joint for arthritic patients. An effective tool for analyzing these implants’ mechanical performance and longevity in-silico is finite element analysis (FEA). ABAQUS FEA was used to statically analyze the von Mises stress and contact pressure on the articulating surface of the bearing component in two newly installed fixed-bearing total ankle replacement implants (the Wright Medical INBONE II and the Exactech Vantage). This bearing component rotates on the talar component to induce primary ankle joint motion of plantarflexion and dorsiflexion. The stress response …

Supersonic Air Inlet Modeling Using The Method Of Characteristics, Shay S. Takei

Master's Theses

The Air Inlet Method of Characteristics Analysis Tool (AIMCAT), a tool based in Python 3, is developed to model supersonic air inlet geometries during the early phases of design. The method of characteristics (MOC) is used to solve the governing equations for an inviscid, irrotational, isentropic, steady, supersonic flowfield. A comparison is made between modeling shock waves implicitly using Mach wave coalescence and modeling them explicitly using oblique shock relations. Multiple test cases are used to assess the accuracy of the tool by comparing to experimental wind tunnel data. Good general agreement was achieved over the majority of the supersonic …
