Analysis Of Vision Transformers And Domain Adaptation In Long-Range Facial Recognition, Zachary Michael Swanson

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Atmospheric turbulence presents a significant barrier to long-range facial recognition, introducing severe geometric distortions and blur that degrade image quality. This thesis investigates deep learning approaches for mitigating these effects, with a focus on transformer based architectures and domain adaptation strategies.

An in-depth benchmarking study was performed using convolutional neural networks (CNNs) and vision transformers (ViTs) on the Husker BRIAR Research Collection from up to 500m (HBRC-500) face dataset. The results demonstrated that vision transformers, particularly hierarchical vision transformers like the shifted-window (Swin) transformer, outperform CNN-based models at long distances due to their ability to model global spatial relationships and …

Cazyme Gene Cluster Diversity In Human Gut Microbiome, Yi Xing

Department of Food Science and Technology: Dissertations, Theses, and Student Research

In gut microbiome research, carbohydrate-active enzyme gene clusters (CGCs) have emerged as key functional units for understanding microbial glycan degradation. Unlike taxonomic or broad pathway annotations, CGCs offer gene-cluster-level resolution and capture substrate-specific microbial functions. However, their diversity and distribution in relation to host metabolic phenotypes, such as obesity, remain poorly characterized. This study tests the hypothesis that the composition and abundance of fiber-targeting CGCs vary between obese and healthy human gut microbiomes, reflecting distinct microbial carbohydrate utilization strategies. To examine this, we constructed a high-quality reference CGC dataset comprising 94,019 clusters from the Unified Human Gastrointestinal Genome and profiled …

A Battle Of Armies: Massive Attack Of Natural Enemies To The True Armyworm Mythimna Unipuncta (Haworth, 1809) (Lepidoptera: Noctuidae) In Forage Crops, Armando Falcon-Brindis, Raul T. Villanueva

Insecta Mundi

Understanding the interactions between plant-host-parasitoid plays a major role in insect pest management. Farmers in the southeastern United States rely on pasture systems for cattle milk and beef production, but the benefits of parasitoids and predators on major lepidopteran pests on pasture lands are still overlooked. Here, we aimed to identify and quantify the effect of parasitism on the true armyworm Mythimna unipuncta (Haworth, 1809) (Lepidoptera: Noctuidae) attacking teff grass Eragrostis tef (Zucc.) Trotter (Poaceae) and crabgrass Digitaria sanguinalis (L.) Scop. (Poaceae) in western Kentucky. In early August of 2023, 547 larvae of M. unipuncta were collected from experimental …

The Enigmatic Samuel Aughey: Nebraska’S Pastor Naturalist, Hugh H. Genoways, Margaret R. Bolick, Mary Anne Andrei

Zea E-Books Collection

Samuel Aughey at age 39 became the first Professor of Natural Science at the new University of Nebraska in Lincoln, serving from 1871 to 1883. He was an ordained pastor of the Evangelical Lutheran Church, with an addendum degree from Pennsylvania College (now Gettysburg College) in 1856 and an A.M. degree two years later. His early pastoral work was in Pennsylvania, but in 1864 he became a home missionary to a church in Dakota City, Nebraska. Aughey’s career at the university was marked with successes and honors, but also criticism and questions about his basic knowledge of the sciences. While …

Why Real Impact Stories Of Forest-Dependent Communities Are Essential In Carbon Marketing, Andrew Mwape

School of Natural Resources: Faculty Publications

As the global carbon market matures, the pressure on companies and project developers to prove the integrity and social value of their carbon offset initiatives has never been greater. At the heart of this growing scrutiny lies a key opportunity: to move beyond metrics and tell authentic, human-centered stories that reflect the real impact of carbon projects; especially those rooted in forest landscapes.

“You Can Rise Back Up Again”: Using Photovoice To Understand Healing From Intimate Partner Violence Among Lgbtq+ Racial-Ethnic Minority College Students, Stephanie Lim

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Intimate partner violence (IPV) is a longstanding public health crisis that has been linked to deleterious mental and physical health issues and negative academic outcomes among college students. Further, IPV disproportionately affects LGBTQ+ individuals and certain racial-ethnic minority students. Campus services are not adequately meeting the needs of these survivors and these efforts would be better informed by centering students disproportionately affected by IPV. Guided by intersectionality and minority stress theories, the current photovoice study examined the strengths that fostered healing and the challenges that LGBTQ+ racial-ethnic minority survivors faced in their recovery journeys. Participants were eight LGBTQ+ racial-ethnic minority …

Farmnav-Uav: A Field-Ready Autonomous Uav For Tracking Static And Dynamic Trajectories In Agricultural Applications, Veera Venkata Ram Murali Krishna Rao Muvva

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

This study presents the design and development of a custom-built uncrewed aerial vehicle (UAV) tailored for precision agriculture. Unlike commercial UAVs, which are often constrained by proprietary systems and limited hardware customization, the proposed platform emphasizes modularity, upgradeability, and cost-effectiveness. The UAV is equipped with a Cube Blue flight controller for reliable low-level actuation and a Raspberry Pi 4 companion computer that executes a Model Predictive Control (MPC) algorithm for high-level trajectory optimization and stability enhancement.

Most conventional UAV autopilot systems rely on non-optimal control strategies, such as proportional–integral–derivative (PID) controllers, which can be inadequate for dynamic or resource-constrained environments. …

Overcoming Vaccine-Associated Enhanced Respiratory Disease In Swine Flu With Lipid Nanoparticle-Dna Technology, The Nguyen

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

The two primary challenges in developing vaccines against swine influenza A virus (IAV-S) are the continuous viral evolution and vaccine-associated enhanced respiratory disease (VAERD). Current vaccine strategies share a common limitation: the significant time required for licensing updated vaccines. Moreover, the strain selection for vaccine updates depends entirely on predictions, raising the risk that chosen strains may not match circulating viruses. Such mismatches not only reduce vaccine efficacy but also risk exacerbating disease severity through VAERD. Here, in this thesis, we developed and evaluated a novel DNA-based vaccine platform designed to address the need for rapid updates in response to …

Simulations Of Differential Reflectivity Columns In Quasi-Linear Convective Systems, Devon Jacob Healey

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Much research over the past decade has revealed that dual-polarization radar is a powerful tool in furthering our understanding of severe storm dynamics and subsequently improving warning strategies for these hazardous events. However, there are currently very few studies examining a particularly prolific severe convective storm mode with dual-polarization radar: quasi-linear convective systems (QLCSs). These storms can occur in any season of the year throughout most of the contiguous United States and can have immense societal impacts. Warning for the hazards produced by QLCSs is currently a significant operational challenge, therefore, research is needed to see if applying dual-polarization radar …

Experiential Learning In Lecture Settings For Ides 200: Programs, Codes & Standards, Emily Cerny

UNL Faculty Course Portfolios

In traditional lecture settings, students take notes from a lecturer’s recitations and have minimal interaction with each other and the world around them. For IDES 200: Programs, Codes & Standards, a key aspect of learning is for students to understand the connections between the concepts learned in class and the built environment. To increase this connection and get students thinking in different manners, experiential learning methodologies were introduced through in-class exercises and within the course assignments alongside typical lectures and lecture comprehension quizzes. By surveying students’ perceptions of assignments and course activities, the goal of this course portfolio is to …

The Sauce To Meat Is Ceremony: Cannibalism And Hospitality Serve As Horror And Culture Tropes In Hannibal And Macbeth, Shay Williams

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

When examining Macbeth (1623) as a case study within Shakespeare’s canon, we see all the obvious horror tropes - murder, witches, a ghost, bodies, blood and gore. What is less pronounced is the horror that lies within eating, drinking, feasting, and the ceremony of banquets. On the other side of the spectrum, and unlike the character of Macbeth, we have a figure that epitomizes all things horror, and has been read about in novels, watched on film, and as of late (2013-2015) has been the subject of a Television show, aptly named: Hannibal. In both works, we encounter men/monsters/killers …

The Connection Between An Unequitable Distribution Of Care Responsibilities And A Widening Gender Nutrition Gap In Latin America, Alexis Nicole Bodlak

Honors Program: Senior Projects (Public)

The notion of care refers to activities that satisfy the basic needs of existence and reproduction. Within rural communities, care work such as the production and preparation of food contributes to food security at the household level. Care work supports the paid workforce, allowing workers to focus on commercial productive activities that generate economic income in rural communities. Women perform 6.3 to 29.5 more hours per week than men in unpaid care work, reducing their time for income-generating activities and personal nutrition management. Affecting their economic independence and ability to access and consume nutritious food. Studies show that in food-insecure …

A Zariski-Nagata Theorem For Smooth Toric Surfaces, Jordan Vincent Barrett

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The Affine Zariski-Nagata theorem is a classical result in commutative algebra that gives an expression for the n^th symbolic power of a radical ideal I in a polynomial ring over a field in terms of the n^th ordinary powers of the maximal ideals in [affine variety]_max(I). In this thesis we discuss a well-known projective analog of Zariski-Nagata and provide the necessary background on toric varieties to present a generalization of this result to toric surfaces. We conclude with a brief discussion about work toward characterizing which abstract toric varieties have smooth point fibers with …

Stop Design: Rethinking The Approach To Public Transit's Architecture, Elizabeth M. Nielsen

Architecture Masters of Science Program: Theses

Public spaces are the foundation of our social health and wellbeing, but are often designed without considering the needs of the public, creating spaces that people do not feel encouraged to use. Just as public space design as a whole often falls short of serving the public, the same can be said for a subset of public space design, public transit stops. While they are public spaces created for the purpose of waiting, their design rarely reflects this.

Well-designed public transit stops are capable of both maintaining existing ridership and drawing in new riders. Most commonly, this design occurs at …

Quality Considerations In The Pedestrian Realm: Dead Space Intervention And Prevention, Alycia Ramage

Masters in Architecture Program: Theses

What if every space deemed “unadmirable” was reimagined as a stage for community life? Efforts to find solutions to this question prompted a more complex question: how can new construction promote interaction between architecture and the pedestrian realm?

This thesis is conducted in three main parts: 1) understanding dead space, 2) reinventing dead spaces in existing conditions, and 3) creating a design handbook that works to minimize dead spaces in new design.

Using Lincoln, Nebraska as a case study, part one begins with observation- looking for spaces that could be deemed unadmirable by a pedestrian. Utilizing research and observation, the …

From In-The-Head To In-The-World: Frameworks For Understanding And Applying Computational Thinking, Justin Olmanson, Gretchen K. Larsen, Azadeh Hassani

Department of Teaching, Learning, and Teacher Education: Faculty Publications

In the five decades since Papert coined the term Computational Thinking (CT), it has become a core framework for thinking about learning, problem-solving, design, and creativity. Although CT is most commonly, and initially, associated with the cognitive orientations involved in coding and learning to code, it also includes situated and critical processes related to computational problem solving. Herein we unpack ways researchers in different fields and points in time have organized CT. We include creative coding as a uniquely generative lens for rethinking CT, outlining its potential as an expressive, constructionist, and culturally situated practice. In doing so, we explore …

Medusa's Metamorphosis: Art, Mythology, And The Changing Perception Of Female Power, Elizabeth Kehr

School of Art, Art History, and Design: Theses and Student Creative Work

The evolution of Medusa’s iconography in ancient Greek art mirrors societal and cultural transformations. As attitudes shifted in relation to gender roles, power relationships, and morality changed, so too did images of the Gorgon. Following the course of development of Medusa’s image allows one to discover details of the thoughts and struggles the ancient Greeks had with concepts of power, womanhood, and monstrosity and otherness. Previous art historical research on Medusa has largely examined her function and evolution of visual depictions from the Archaic monster to Classical ideal. Few, however, have explored how and why these changes may be indicative …

Illustrating Identity: Ethel Reed’S Art Posters And Women's Claims To Public Space In Fin-De-Siècle Boston, Miranda R. Knofczynski

School of Art, Art History, and Design: Theses and Student Creative Work

Much scholarship has uncovered the history of women illustrators during the late nineteenth century. The rebuilding of these lost histories calls for research which theorizes women’s contributions to the burgeoning arts scene of the fin-de-siècle. This thesis will examine the posters Ethel Reed created for different companies during the height of the 1890s poster craze and discuss how she articulated women in public space in them. Reed’s art offers an aestheticized yet feminist visualization of women engaging in leisure activities such as exploring the city, reading, or attending the theatre. Many have described the women in her posters as merely …
