Comparing Phosphorus Removal Efficiencies And Mechanisms Via Two Cost-Effective Specialty Adsorbents In A Cascade Upflow Filtration System, Sydney Kilgus-Vesely

Honors Undergraduate Theses

Finding solutions to treat water that contains phosphorus is an important effort due to the harmful impacts it presents to both human health and the environment. Phosphorus is considered a limiting factor in water oftentimes and therefore controls the growth of algal bloom in a water body. The increase of algal populations due to wastewater effluent, stormwater runoff, and agricultural discharge in Florida waters has a direct link to the event of harmful algal blooms such as red tide in coastal regions, eutrophication of waterbodies, and fish kills. Finding low cost, energy efficient, and low maintenance green sorption media (GSM) …

A Framework For The Automatic Identification Of Optimized Yield Surface Parameters, Kevin Hanekom

Honors Undergraduate Theses

Advanced engineering materials are designed to display tensile-compressive asymmetry (TCA) and anisotropy to provide unique attributes to critical components necessary in the hot section of turbines. The never-ending chase for higher efficiencies, and with them, higher temperature gradients, intrinsically leads to more and more of these complex materials, like single crystal turbine blades, embedded within the turbine environment. Mathematical models, known as yield criteria, allow engineers to visualize the mechanical behavior of these materials in various orientations under complex loading. Yield criteria are dependent on three key items in determination of their governing parameters: material test data, mathematical constraints, and …

An Evaluation Of Thermocouple Reconstruction Techniques, Derek Brauneis

Electronic Theses and Dissertations, 2020-2023

Temperature measurements can be difficult to obtain across many different harsh environments such as engine combustion chambers, engine exhaust temperatures, and explosion fireballs. While there are alternate methods to measure fluid temperature such as laser measurements, acoustic measurements, and camera imaging techniques, these methods can often be expensive, difficult to implement, and not able to see within the environment. Thermocouples are popular sensors because they are cheap and easy to implement across a wide range of applications and can measure temperature in areas where other methods cannot reach or see. However, while these sensors are very popular and versatile, they …

Gait Strategies While Walking With Discrete Perturbations On A Self-Paced Treadmill, Cesar Castano

Electronic Theses and Dissertations, 2020-2023

Introducing perturbations on a self-paced treadmill allows participants to experience uncertain environments without restricting their ability to continuously change their walking speed and kinematics. In this dissertation, I evaluated how different self-paced treadmill controller sensitivities affected gait parameters and variability on decline, level, and incline slopes. I also investigated how healthy young and older adults adjust their gait strategies when responding to perturbations of varying unpredictability and whether the changes in gait strategies remained once the perturbations were no longer present. Lastly, I evaluated how differences in gait kinematics when responding to visual and mechanical perturbations at varying frequencies. I …

Avicenna's Doctrine Of Emanation And The Sphere Of The Heavens, Brian C. Manere

Honors Undergraduate Theses

Avicenna argues that the celestial spheres each have a soul, termed the motive soul, which is emanated by the first celestial intellect––a body of knowledge which knows itself. Despite outlining the powers of the motive soul, Avicenna does not formally investigate the psychology of the spheres nor their volition. Rather, he presents their volition as a mystery and leaves it to posterity to solve. In an attempt to resolve this mystery, I will argue that it is a direct result of Avicenna having purposefully written a repeated gap into his account of emanation such that there is no clear account …

Defining Creativity And Its Role In Marx's Philosophy, Carlos Avila

Honors Undergraduate Theses

The intent of this thesis is to explore the concept of creativity as it appears in the major works of Karl Marx and to attempt to discern its role in the emancipatory political project that Marx proposes. Contemporary understandings of creativity still rely upon notions of the artist-genius, locating the "true" expression of creative freedom in the work of art. A more recent development is the commodification of creativity as a quality of a good worker, who is now expected to find innovative ways of doing their job more efficiently. Both of these ideas about creativity allow for our creative …

Korean Poetry: A Discussion And Translation, Kassidy N. Menk

Honors Undergraduate Theses

Korea's history has had a deeply influential and significant impact on its modern language, and concomitantly, on the country's modern poetry and prose. Despite the artistic and literary value, there is a substantial lack of English translations available for Korean works. The continued rapid development of Korean and its considerably different grammar and syntax often pose difficulties for English translators. Korean poetry, specifically, follows a form unfamiliar to English readers which makes interpretation for translation challenging. This thesis hopes to provide context for the lack of scholarly translations of Korean poetry by discussing the historical and linguistic context of the …

Pepper Pot And Callaloo: Caribbean Cuisine As Embodiment Of "Otherness" And Resistance, Sheina Senat

Honors Undergraduate Theses

The thesis intends to analyze the Caribbean as more than "elsewhere" in modernism through food research. The Eurocentric viewpoint is that the islands are the "other" and that the Caribbean's contributions are not central to the past and present. Representations of food in Caribbean literature reveal dualism, such as Western/African in the tropic's identity, and this dualism can lead to identity issues. Chapter 1 analyzes Caribbean cuisine's mosaic origins from Indian, European, Native, and African influences. Food imagery in Caribbean literature does not separate the Caribbean from its complicated past. However, it notes that the islands should embrace their differences …

Literature As A Form Of Resistance Against British Colonial Rule In India, Ebada Wasiuddin

These publications look at the outcomes of Europe's intent to colonize and its impact on the marginalized, colonial subjects down to the personal level. Delving into the tragic reality of colonialism and investigating its impact as portrayed in the novels selected, this thesis argues that the selected texts operate as resistance literature subverting the colonial discourse in retrieving South Asian culture and history. This project explores specific forms of resistance within the tropes of memory, history, and gender to pose a larger question of decolonial futures …

Wild Wild Country: Netflix, Orientalism, And The Guru, E. K. D. Wood

Honors Undergraduate Theses

Recent years have produced an influx of popular documentaries of Indian gurus who founded transnational spiritual communities and became embroiled in various forms of controversy. One example of this is Wild Wild Country, a 2018 Netflix documentary that depicts the rise and fall of a spiritual community, started by an Indian guru named Osho (1931-1990) in a failed attempt to build a utopian commune in Oregon. American representations of Asian religious figures have historically been a complex, and often prejudiced, affair. This thesis will attempt to assert the best fit theoretical framework with which to interpret Wild Wild Country …

Treatment Of The Differently Abled: Representations Of Disability From Victorian Periodicals To Contemporary Graphic Narratives, Rachelle Echevarria

Honors Undergraduate Theses

In recent years, a number of efforts have been made to promote diversity, equity, and inclusion in academic institutions, the workplace, and to examine and analyze representations of marginalized populations in a variety of literary and cultural contexts. These efforts usually acknowledge past mistakes, emphasizing the idea that history shall not and should not repeat itself. While analyzing the representations of disability is important in its own right, it's also important to understand why these perceptions exist. This thesis suggests that when the representations of disabilities from different mediums and from different time periods are examined in relationship, readers may …

Despite the clear correlation between Hip-Hop culture and literary works from the early …

Spilling The Tea: A Comparative Analysis Of Development In Ex-British Colonies, Niamh L. Harrop

Honors Undergraduate Theses

The British Empire was the largest empire the world has ever seen, and as such, has significantly impacted many of the countries it formerly held as colonies. Imposing a Western style of governance would change the political operations of a nation and would fundamentally shift power dynamics within the country. Through a review of the existing literature on the subject, this thesis examines the effects that British imperial rule had on four different countries in both their social and economic development in the post-colonial era. Overall, the results indicate that Britain failed to set their colonies up for long-term development …

Before They Could Be Saved: Aids Voices Before Protease Inhibitors, Julian J. Willis

Honors Undergraduate Theses

The intent of this thesis is to explore writing during the start of the AIDS epidemic in the U.S. States. This time period encompasses the early 1980s to mid-1990s before Protease Inhibitors were FDA approved which was the medical breakthrough drug that helped turn an HIV diagnosis from a death sentence to a chronic condition.

An Exploration On The Spanish Caribbean Dialectical Community: ¿Unidos O Separados?, Bryan J. Jimenez

Honors Undergraduate Theses

Latin America holds a diverse array of people and language. Even regions and countries that speak the same language tend to speak it differently. This leads to interesting variations in language and speech. Most people of Latin American origin are able to note that Mexican Spanish and Puerto Rican Spanish are different in terms of intonation, speech pattern, vocabulary, and more. Most popular theories that section Latin America off by dialects group the entirety of the Spanish-speaking Caribbean into a single dialectical community. Cuba, Puerto Rico, and the Dominican Republic each hold unique histories and are home to a fascinating …

The thesis introduces two aspects–spiritual and spatial–to the wounds suffered by the Chicana collective Self which can be found within the characters and plotlines of lara silva's stories, and which had previously been outlined by Anzaldúa herself. This thesis also explains in depth the steps necessary to achieving the never-ending Coyolxauhqui Imperative, which is Anzaldúa's idea that to heal the collective Self, individuals must continue to create and tell the …

Political Bodies In The Ulster Cycle: Space, Conflict, And Comedy In Scéla Muicce Meicc Dathó, Glenn S. Ritchey Iii

Honors Undergraduate Theses

Scéla Muicce Meicc Da Thó (SMMD; The Tale of Mac Da Thó's Pig) is a humorous Old Irish myth that takes its cues from its Ulster Cycle cousins, notably, An Táin Bó Cúailnge (The Cattle Raid of Cooley). The connective tissue is its cast, plot structure, and the author's mastery of cultural and storytelling traditions. SMMD is brief and rapid, which aids its near-absurdist representation of masculinity, kingship, and honor in heroic saga culture. This thesis uses postcolonial and medieval literary scholarship to analyze medieval and modern depictions of the Ulster Cycle. Contemporarily, the Irish …
