Interior Point Optimization Of Low-Thrust Spacecraft Trajectories, Jordan D. Frederiksen

Master's Theses

Low-thrust interplanetary spacecraft trajectory optimization poses a uniquely difficult problem to solve because of the inherent nonlinearities of the dynamics and constraints as well as the large size of the search space of possible solutions. Tools currently exist that optimize low-thrust interplanetary trajectories, but these tools are rarely openly available to the public, and when they are available they require multiple interfaces between multiple different packages. The goal of this work is to present a new piece of low-thrust interplanetary spacecraft trajectory optimization software that is open-source and entirely self-contained so that more people can have access to the ability …

Take The Lead: Toward A Virtual Video Dance Partner, Ty Farris

Master's Theses

My work focuses on taking a single person as input and predicting the intentional movement of one dance partner based on the other dance partner's movement. Human pose estimation has been applied to dance and computer vision, but many existing applications focus on a single individual or multiple individuals performing. Currently there are very few works that focus specifically on dance couples combined with pose prediction. This thesis is applicable to the entertainment and gaming industry by training people to dance with a virtual dance partner.

Many existing interactive or virtual dance partners require a motion capture system, multiple cameras …

Intercropping And Denisity Impacts In A Lettuce And Chard Agroecosystem, Sophia Moser

Master of Science in Environmental Sciences and Management Projects

Conventional agriculture that uses machinery management, synthetic fertilizers, and pesticides, is a contributor to greenhouse gas emissions, reduction of biodiversity and soil health. Agroecological methods, such as intercropping, have the potential to make farming more sustainable, financially feasible and to be implemented on a large scale. Gaps in agricultural research have led to limited information as to how intercropped arrangements can be adapted to be as productive as conventional systems. This research evaluates the ecological and economic performance of a lettuce and chard agroecosystem, specifically investigating the impact that density and intercropping has on plant productivity and profitability. Both species …

Comparison Of Two Advanced Oxidation Processes For Their Production Of Hydroxyl Radicals And Evaluation Of A Uv/Ozone Aop At Varying Uv Fluence For Treating Diclofenac, Alexandra Cass

Master's Theses

This study explores the efficacy of two advanced oxidation processes for generation of hydroxyl radicals to promote degradation of emerging contaminants. Drought and water shortage have become pressing issues caused by our world’s changing climate. Water reclamation and reuse are increasingly important options for relieving this water stress. Water reuse runs the risk of reintroducing recalcitrant compounds that can accumulate in our bodies and environment. Advanced treatment methods that degrade these compounds are vital to protect our health and the health of the environment while providing necessary water resources. Advanced oxidation processes (AOPs) have shown great promise for removing recalcitrant …

Comparison Of Animal Versus Plant-Based Protein Supplementation To Nitrogen Balance In Female College Students, Adeline Maykish

Master's Theses

Plant-based diets have become popular in the past 10 years, with approximately 11% of Americans self-identifying as vegan or vegetarian, and many others trying to reduce meat consumption. Due to this increasing interest, the plant-based food market has exploded with several novel innovative products serving as alternatives to animal-based products. One such example is almond protein powder, a fairly new protein supplement created as an alternative to whey protein. A number of studies have compared animal-based protein supplementation, such as whey to plant-based supplementation, such as soy, on muscle protein synthesis and skeletal muscle preservation. Due to the novelty of …

Master's Theses

This paper examines vineyard perceptions and adoption of climate change adaptation and water conservation measures in the Paso Robles American Viticultural Area (AVA). A survey was distributed to all 220 vineyards and vineyard management companies that operate in the AVA, with a 53.64% response rate. The objective of the survey was to determine vineyard manager and owner attitudes towards climate change and adaptation, as well as their perceptions of how these threats would impact their operation. A second objective was to document the current level of water conservation and climate adaptation while identifying the barriers and opportunities for further adoption …

The Preconstruction Work For The Shaded Structure At Growing Grounds, Grace Gv Brekke

Construction Management

When beginning a project, one must take vast consideration into the plan. For a construction project, this means considering how long the project will take, how much it will cost, what materials will be used, who will build it, where the money will come from, and who will utilize the space. This paper analyzes all this preconstruction work for a shaded structure at Growing Grounds. The Growing Grounds shared community space in San Luis Obispo, California, provides incredible resources and opportunities to the people in the area that struggle with mental health. Through horticulture, the volunteers must work hard to …

Housing And Urban Development Home Development And The Future Of The Industry: Case Study, Nolan J. Binkele

Construction Management

A HUD home is a 1-4 unit residential property acquired by HUD (Housing and Urban Development) as a result of a foreclosure action. These homes tend to be priced slightly below market value in order to regain past losses. The Department of Housing and Urban Development has developed a building code to classify manufactured homes as HUD. Although manufactured homes are typically sold to single property owners, I hypothesize that building them in a tract form can benefit a community by providing affordable, adequate housing for low income families and single families. I also hypothesize that HUD home development will …

Reasons And Remedies To The Dying Plant Walls, Hayley Q. Mcgough

Construction Management

Sustainability in construction has been increasingly popular and detrimental with the state of the planet and climate change. One of the more popular solutions is the addition of plant façades to a building, which are plants that are put on the vertical of a building. The benefits that come with plant facades include and are not limited to: Reduction of the urban heat island effect, improved air quality, local job creation, improved energy efficiency, building structure protection, noise reduction, increased biodiversity, urban agriculture. These benefits are not reaching their full potential because these plant façades keep dying creating a bigger …

The Intuitiveness Of Animal Rights: Audi's Epistemology, Kantian Ethics, And Regan's Case, Andrew Nesseler

Between the Species

In this paper, I will argue that ethical intuitionism and Robert Audi’s work on its moral epistemology as applied to Kant’s formula of humanity can offer grounding and support for an animal rights position that approaches that of a view articulated by Tom Regan. The combination of these positions will be done by testing our intuitions concerning non-rational individuals—leading one, I argue, to an animal rights view. Then I will briefly note the skeptical concerns about the role of intuitions in our knowledge of the moral status of human animals and non-human animals alike. Ultimately, I will conclude that intuitions …

An Evolving Face-To-Face Freshman Experience Course During A Pandemic, Allen Estes, John Lawson

Architectural Engineering

With the full effect of the COVID-19 pandemic reaching the United States in March 2020, almost all colleges and universities went exclusively to virtual on-line instruction during the spring semesters and quarters. In the fall, according to the College Crisis Initiative study at Davidson College of 3000 schools, as colleges opened back up 4% were fully in person, 23% primarily in person, 21% were hybrid, 34% primarily on line, 10% fully on line and 8% either undetermined or other. Some colleges selectively reopened specific classes for face-to-face instruction with varying degrees of success and some had to quick shut down …

Making Patriots Of Pupils: Colonial Education In Micronesia From 1944-1980, Julia Taylor

The Forum: Journal of History

This article explores American colonial education in Micronesia from the final months of World War Two to the late 1970s. The primary research question concerns American usage of education to pursue political and military goals, and how this affected multiple dimensions of Indigenous life. Although the dominant narrative at the time blamed Indigenous people for difficulties in implementing American education, the Western values permeating the American consciousness significantly inhibited the possibility of success as Americans defined it. This article details American motivations and efforts to implement an educational system as part of a larger goal of “economic development” and analyzes …

Forgotten Crime And Cultural Boom: New York And Brazil's Coffee Trading Relationship In The Early Twentieth Century, Collin Green

The Forum: Journal of History

In the United States of America, coffee and its ever-evolving culture has become a focal point of everyday life. However, we did not just stumble upon this phenomenon; the popularity of coffee was carefully calculated by leaders of the wealthiest coffee companies of the early 20th century in America’s biggest city, New York. In this paper, the history of the powerful coffee trading relationship between Brazil and New York is analyzed on two different levels. Firstly, I examine how New York's big coffee companies successfully participated in criminal activity on an international and national level. Secondly, my focus shifts to …

Not So Dystopian: A Historical Reading Of Eugenics In Science Fiction, Riley Sanders

The Forum: Journal of History

Broadly, this paper is an effort in complicating traditional readings of eugenic themes in science fiction. Two landmark novels, Wells’ The Island of Dr. Moreau (1896) and Huxley’s Brave New World (1932), are highlighted as representative of the early and late stages of eugenics. By focusing on the troubling historical context surrounding these authors, I denounce the simple reading of these works as merely “dystopian”. Scholars like Francis Fukuyama advance these simplistic readings by instinctively assuming that Wells and Huxley were against eugenics. This paper continues the tradition that David Bradshaw popularized in his book The Hidden Huxley, which argues …

The Literary Controversies Of Michelangelo's Sistine Ceiling, Victoria Duehring

The Forum: Journal of History

This literary review will focus on Michelangelo’s most significant work of color: the Sistine ceiling. Michelangelo’s work has spawned a plethora of literature, but this paper will focus on three main controversial topics: assistants (or lack thereof), the ignudi’s purpose, and restoration. I will also apply a psycho-historical approach to these controversies and identify potential avenues for future research.

Stigma On Campus: The Precarious Situation Of Iranian Students At Cal Poly, November 1979, Chance Coates

The Forum: Journal of History

Exploring the ways in which the seizure of the American embassy and subsequent hostage situation of American nationals within Tehran in 1979 transcended international boundaries, this paper discusses the backlash that Iranian students at Cal Poly faced during this pivotal geopolitical crisis. In doing so, I review various protests and public statements that gave rise to a distinct social discourse that stigmatized Iranian students, effectively transforming this group into an “Other.” Further, I explore the ways in which the university as an institution contributed to this stigmatization. The paper overall concludes that the Iranian students on campus were, like the …

A Lifeline For Millions: American Relief In An Age Of Isolationism, Matteo Marsella

The Forum: Journal of History

American military involvement in the Great War is a widely discussed aspect of the conflict. The period following the war is often considered an example of American isolationist foreign policy. Lesser well known are American efforts to provide food relief to starving populations in Europe, which began during and continued well after the war's conclusion. This paper seeks to locate American relief efforts within broader postwar foreign policy. Although President Harding’s 1920 election victory on a platform of a “return to normalcy” is often construed as a rejection of Wilsonian internationalism and a return to prewar isolationism, there is no …

Medieval Infertility: Treatments, Cures, And Consequences, Zia Simpson

The Forum: Journal of History

Since the first civilizations emerged, reproductive ability has been one of the most prominent elements in assessing a woman’s value to society. Other characteristics such as beauty, intelligence, and wealth may have been granted comparable consequence, but those are arbitrary and improvable. Fertility is genetic, and for centuries it was beyond human control. Among the medieval European nobility, fertility held even greater power. The absence of an heir could, either directly or indirectly, bring about war, economic depression, and social disorder. Catholicism provided a refuge by allowing barren women to retain their hopes, while simultaneously enriching Rome’s coffers. Other women …

The Purpose Of Shanties From The Time Of Sailors To The Musical Masters Of The Twentieth Century, Madison Grant

The Forum: Journal of History

The folk songs of the high seas traveled across hundreds of ships, changed in sound and lyric, and ultimately became known today as maritime folk music. Although many historians choose to analyze maritime history through physical artifacts, one less-appreciated aspect of the sea is known as the sea shanty. With modern musicians paying homage to their older nautical counterparts, the revival of shanty tunes sprung forth an almost lost appreciation into the lives of both historians and musicians alike. Referenced in this essay is the James Madison Carpenter Collection, an array of recorded and inscribed sources of shanty tunes that …

These …

Netting Nemo: A Moral Ontology For The Scaled And Slimy, Zachary Piso

Between the Species

Here I develop an ontology of aquarium fish that articulates the relationships that many fishkeepers hold with their fish and considers how these relationships generate moral responsibilities. The investigation explores the norms already regulating hobbyist discourse and practice, charting the values that are cited to justify recommendations and restrictions and demonstrating how morally responsible fishkeeping participates in a particular moral ontology. Principally I aim to show that the subject of moral consideration in fishkeeping is rarely the individual fish and only sometimes the fish species, but paradigmatically the “community tank.” In getting fish, one has responsibilities to pair compatible species …
