Wildfire Risk Assessment Using Convolutional Neural Networks And Modis Climate Data, Sean F. Nesbit

Master's Theses

Wildfires burn millions of acres of land each year leading to the destruction of homes and wildland ecosystems while costing governments billions in funding. As climate change intensifies drought volatility across the Western United States, wildfires are likely to become increasingly severe. Wildfire risk assessment and hazard maps are currently employed by fire services, but can often be outdated. This paper introduces an image-based dataset using climate and wildfire data from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS). The dataset consists of 32 climate and topographical layers captured across 0.1 deg by 0.1 deg tiled regions in California and Nevada between …

Distribution And Ecological Function Of Pacific Lamprey In The San Luis Obispo Creek Watershed, Parker Kalan

Master's Theses

Pacific lamprey (Entosphenus tridentatus) is an endemic species to coastal watersheds along the Pacific Rim in North America and Asia. The species' geographic distribution is retracting and has not been mapped precisely, and the ability for the species to provide ecosystem services, such as water filtration, for supporting watershed management has not been tested. The San Luis Obispo Creek watershed, California, USA is at the southern end of Pacific lamprey’s retracting distribution, and the San Luis Obispo watershed is impacted by degraded water quality, making investigation of Pacific lamprey in the San Luis Obispo Creek watershed of direct …

Specialized Named Entity Recognition For Breast Cancer Subtyping, Griffith Scheyer Hawblitzel

Master's Theses

The amount of data and analysis being published and archived in the biomedical research community is more than can feasibly be sifted through manually, which limits the information an individual or small group can synthesize and integrate into their own research. This presents an opportunity for using automated methods, including Natural Language Processing (NLP), to extract important information from text on various topics. Named Entity Recognition (NER), is one way to automate knowledge extraction of raw text. NER is defined as the task of identifying named entities from text using labels such as people, dates, locations, diseases, and proteins. There …

Increasing The Effectiveness Of K-12 Stem Worshops Through Targeted Context And Creative Technolgies, Melina Lopez

Master's Theses

Economic projections reveal a need for one million more Science, Technology, Engineering, and Math (STEM) professionals over the next decade than the United States is producing at the current rate.

Bearings are the essential components of modern rotating machines. Bearing faults can cause severe machine damages or even breakdowns.

In recent years, artificial intelligence and deep learning have been successfully applied to fault detection. In this thesis, convolutional neural networks (CNN) are employed for bearing fault detection and classification. Computer simulations results demonstrate that the CNN based approach is advantageous over the conventional regression model, with an overall accuracy of 99.5%.

Effects Of Experimental Scale On The Adsorption Of Two Pharmaceutical Drugs Detected In Municipal Wastewater Effluent, Michael Moore

Master's Theses

Pharmaceutical drugs are being produced and consumed in increasing quantities every year and are poorly treated by conventional wastewater treatment processes, leading to increasing detection of such compounds in surface water, groundwater, and municipal drinking water. Soil aquifer treatment (SAT) is a promising method for treating these emerging compounds through combined adsorption and degradation of target compounds in soil. This thesis examines the consistency of results from typical studies like adsorption isotherms and soil columns utilized in analysis of SAT performance, across varying experimental scales. The adsorption behavior of two pharmaceuticals was investigated as a function of experimental scale and …

Improving Relation Extraction From Unstructured Genealogical Texts Using Fine-Tuned Transformers, Carloangello Parrolivelli

Master's Theses

Though exploring one’s family lineage through genealogical family trees can be insightful to developing one’s identity, this knowledge is typically held behind closed doors by private companies or require expensive technologies, such as DNA testing, to uncover. With the ever-booming explosion of data on the world wide web, many unstructured text documents, both old and new, are being discovered, written, and processed which contain rich genealogical information. With access to this immense amount of data, however, entails a costly process whereby people, typically volunteers, have to read large amounts of text to find relationships between people. This delays having genealogical …

Model-Based Design Of An Optimal Lqg Regulator For A Piezoelectric Actuated Smart Structure Using A High-Precision Laser Interferometry Measurement System, Grant P. Gallagher

Master's Theses

Smart structure control systems commonly use piezoceramic sensors or accelerometers as vibration measurement devices. These measurement devices often produce noisy and/or low-precision signals, which makes it difficult to measure small-amplitude vibrations. Laser interferometry devices pose as an alternative high-precision position measurement method, capable of nanometer-scale resolution. The aim of this research is to utilize a model-based design approach to develop and implement a real-time Linear Quadratic Gaussian (LQG) regulator for a piezoelectric actuated smart structure using a high-precision laser interferometry measurement system to suppress the excitation of vibratory modes.

The analytical model of the smart structure is derived using the …

Animal-Rights Primitivism: A Vital Needs Argument Against Modern Technology, James Robert Schultz

Between the Species

In this essay, I argue that those who embrace animal rights should also embrace primitivism—the view that humans should abandon modern technology and take up something like hunter-gatherer technology instead. I call my view “animal-rights primitivism” to distinguish it from human-centered arguments for primitivism. In particular, I employ a vital-needs framework to make my argument. I argue that hunter-gatherer technology is the least harmful kind of technology, it is sufficient to meet human vital needs, and it is possible for humans to make the transition to hunter-gatherer technology while still meeting their vital needs. Alternatively, I argue that even if …

Has The Philosophical Case For Animal Liberation Been Proved? A Systematic And Narrative Review Of The Philosophical Literature 1975-2020., Michael Morris

Between the Species

I test the hypothesis proposed by Peter Singer that the philosophical case for animal liberation has been won, through a systematic review of papers published by philosophers between 1975 and 2020.

There was a slight but statistically significant correlation between support for an animal liberation vegan position, with year of publication. Support for a better treatment of animals than currently sanctioned by society increased significantly among papers discussing general principals of animal ethics.

Findings support a weaker version of Singer's hypothesis. Among the philosophical community there is greater support for animal liberation, but the debate has not been ‘won’.

The Threat Of Returning To “Normal”: Resisting Ableism In The Post-Covid Classroom, Sarah M. Parsloe, Elizabeth M. Smith

Feminist Pedagogy

The abrupt switch to online learning during the COVID-19 pandemic highlighted pervasive ableism; accommodations that had been “impossible” were suddenly available. This critical commentary draws from interviews with 16 students and our own ethnographic accounts as student/professor to understand how COVID shaped disabled experiences in the classroom. As a student with a disability, Elizabeth was hyperaware of her vulnerability to illness, but also experienced herself as less impaired online. She could control her learning environment to minimize sensory and mobility challenges. Additionally, professors’ flexible policies helped her to manage energy, time, and symptoms. However, Elizabeth and her peers feared an …

Sharing Walks As A Witnessing Practice: Exploring Movement-Based Pedagogies, Catalina Hernandez-Cabal

Feminist Pedagogy

How we walk—or our inability to do so—is telling of who we have been. I propose this simple movement practice as a pedagogical engagement with the concept of faithful witnessing, which refers to attending to modes of power unbalance that might go unnoticed, and to people's creative and resistant possibilities (Lugones, 2003; Figueroa-Vásquez, 2015). This activity is suggested to provoke reflections about how we understand and experience social difference and power unbalances. The work introduces a simple score (a creative prompt) to explore walking-with others, creating instructions to teach others our movement, learning others', and delving into conversations concerning the …

Fate Of Listeria Monocytogenes On Two Salad Blends At Ideal And Abusive Temperatures, Taran Virdi

Master's Theses

The consumption of ready-to-eat (RTE) foods has increased with popular RTE salad blends including non-traditional ingredients such as shredded Brussels sprouts, kale, red and green cabbage, chicory, and broccoli stalk. Concurrently, there has been an increase in the number of foodborne illnesses and outbreaks associated with leafy greens. The potential risk associated with these ingredients must be addressed as they have not typically been consumed raw, especially since L. monocytogenes continues to be a leading cause of foodborne illnesses and outbreaks. This study evaluated the survival of L. monocytogenes on two RTE salad blends at refrigeration, mildly abusive, and abusive …

Electrical Engineering

With the onset of the post-pandemic virtual classroom world, more and more classes are attempting hybrid-style instruction. To accomplish that, recordings of lectures are widely used, with presentation-sharing & audio recording capability. However, video recordings of lectures, with the ability to see the board, lab equipment, and the professor, are the optimal way to give the virtual students the best experience. Right now, technology is readily available for static camera recordings of lecture halls, but this may not suffice when it comes to larger lecture halls and lab demonstrations, where directed shots of equipment or the whiteboard are needed in …

Impact Of Sex On Proliferation And Maturation Of Primary Isolated Myoblasts, Elsa M. Bean

Biomedical Engineering

Peripheral arterial occlusive disease (PAOD) is caused by the buildup of atherosclerotic plaque causing restriction in blood flow in tissue, known as ischemia. It affects 8 million people in the United States and can hinder daily life through the onset of symptoms such as intermittent claudication and in extreme cases ulcers and gangrene. Surgical revascularization is not accessible to certain patient populations, such those of advanced age, highlighting a need for alternative therapies. For example, naturally occurring bypass arteries, called collateral blood vessels, can remodel and enlarge to bypass the occlusion. This process, known as arteriogenesis, has been studied as …

Integrating Fire Responses To Combat Wildfires, Jonathan Leonard Badal

Electrical Engineering

Each year wildfires cause significant loss of property, worsen people’s health, and destroy multiple ecosystems. On average, a wildfire season costs anywhere from 7.6-62.8 billion dollars due to fire containment, repair, and restoration [1]. It can take decades to recover from the crippling loss of land and take even longer to fully restore it. However, with the implementation of a robust early detection system, these losses can be significantly reduced. The current process for identifying wildfires involves visual identification, phone call alerts, and media tools primarily driven by park rangers and public reporting. Unfortunately, this system is not preventative and …

Political Socialization Of College-Age Individuals In The Age Of Social Media, Spencer G. Lowe

Communication Studies

This study used personal reflection, surveys, and interviews to study the political socialization of those that attend college. Previous research has shown that many facets of one’s life can affect their political socialization, such as their familial upbringing or religious ties, and that adolescence is a time in which many individuals go through a significant shift in their political and ethical views. However, a new influence—social media—has begun to greatly affect the political views and shifts of college-age individuals. After personal reflection upon the experiences that caused one such shift, a survey and a series of four interviews of those …

A Research Framework And Initial Study Of Browser Security For The Visually Impaired, Elaine Lau, Zachary Peterson

Master's Theses

The growth of web-based malware and phishing attacks has catalyzed significant advances in the research and use of interstitial warning pages and modals by a browser prior to loading the content of a suspect site. These warnings commonly use visual cues to attract users' attention, including specialized iconography, color, and an absence of buttons to communicate the importance of the scenario. While the efficacy of visual techniques has improved safety for sighted users, these techniques are unsuitable for blind and visually impaired users. This is likely not due to a lack of interest or technical capability by browser manufactures, where …
