Plant Disease Detection Through Convolutional Neural Networks: A Survey Of Existing Literature, Best Practices, And Implementation, Kevin Label

Master's Theses

In the United States alone, common diseases spread among plants account for billions of dollars lost in crop yield each year. This issue is exacerbated in countries with less infrastructure to defend against crop epidemics, and can lead to famine and forced migration. Farmers can seek the help of plant pathology experts to defend against diseases and detect crop irregularities early on. However, access to experts can be difficult, and even those trained in the field may miss symptoms before it is too late. To assist in early disease detection, a number of papers have been released on the potential …

Adapting Single-View View Synthesis With Multiplane Images For 3d Video Chat, Anurag Venkata Uppuluri

Master's Theses

Activities like one-on-one video chatting and video conferencing with multiple participants are more prevalent than ever today as we continue to tackle the pandemic. Bringing a 3D feel to video chat has always been a hot topic in Vision and Graphics communities. In this thesis, we have employed novel view synthesis in attempting to turn one-on-one video chatting into 3D.

Effects Of Nitrogen Management And Cultivar On Strawberry Production Under Disease Pressure, Kamille A. Garcia-Brucher

Master's Theses

Effects of nitrogen management and cultivar on strawberry production under disease pressure

Kamille Garcia-Brucher

California strawberry growers face increasing regulatory pressures to manage nitrogen (N) applications in their production system. Standard practice in the California strawberry industry is to apply a synthetic pre-plant controlled release fertilizer (CRF) to ensure the crop has sufficient N during winter establishment. Some research from the UC Cooperative Extension suggests this practice is not efficient at delivering N to the crop since most of the N is released from CRF before strawberry crop N uptake is significant. Another concern for California strawberry growers is loss …

Classifying Electrocardiogram With Machine Learning Techniques, Hillal Jarrar

Master's Theses

Classifying the electrocardiogram is of clinical importance because classification can be used to diagnose patients with cardiac arrhythmias. Many industries utilize machine learning techniques that consist of feature extraction methods followed by Naive- Bayesian classification in order to detect faults within machinery. Machine learning techniques that analyze vibrational machine data in a mechanical application may be used to analyze electrical data in a physiological application. Three of the most common feature extraction methods used to prepare machine vibration data for Naive-Bayesian classification are the Fourier transform, the Hilbert transform, and the Wavelet Packet transform. Each machine learning technique consists of …

On The Mobility Of Small Aperture Telescopes For Initial Orbit Determination And Apparent Magnitude Derivation Of Low Earth Satellites, Jonathan Ian Hernandez

Master's Theses

Maintaining Space Domain Awareness (SDA) of satellites in low Earth orbit (LEO) requires effective methods of tracking and characterization. Optical measurements of these objects are generally sparse due to limited access intervals and high angular rates. Light pollution and geographic obstructions may also preclude consistent observations. However, a mobile small aperture telescope grants the ability to minimize such environmental effects, thereby increasing capture likelihoods for objects within this regime. By enhancing LEO satellite visibility in this way, extensive orbital and visual data are obtainable.

An 8-inch Meade LX200GPS telescope equipped with a Lumenera SKYnyx2-0M CCD camera comprises the system that …

Collateral Damage: How Expanding Public Charge Policy Influences Adult Esl Enrollment, Allison M. Eckert

Master's Theses

This study used statistical analysis of enrollment records for ESL programs at community colleges throughout California from 2015-2019 to determine whether adult immigrants’ participation in public ESL programs was reduced under President Donald Trump. Immigrant families’ lesser use of public education services and means-tested federal benefits has been widely documented in the wake of Trump’s expansion of the public charge rule, which counted immigrants’ use of a wider array of public benefits against their case for residency in the United States than had any previous iteration of the rule. Failing the public charge test can block an immigrant’s entry into …

Get Into It: Unpacking The Relationship Between Hegemonic Norms And The Race And Gender Of Pop Artists, Bailey Shelton

Master's Theses

Many contemporary popular musical artists are victims of media controversy while they simultaneously make musical chat history. As a culture founded and sustained by a white supremacist capitalistic patriarchy, race and sex appear to influence the way hegemonic in-groups treat minorities and the way minorities are perceived and live within the confines of said hegemony. With the context of understanding feminist theories, hegemonic norms, parasocial relationships, celebrity appeal, and norms, the researcher wanted to understand if there are clear relationship among these frameworks in modern society. This study employed a 2x2 2between subjects factorial design method to gather information about …

For Cause And Countries: Initial, Sustaining, And Combat Motivation In The Royal Air Force Eagle Squadrons, 1940-1942, Timothy Defazio

Master's Theses

Before the United States entered the Second World War, 245 American pilots pledged their service to the Royal Air Force (RAF). Organized into 71, 121, and 133 Squadrons, collectively known as the Eagle Squadrons, these foreign volunteers present an intriguing avenue of soldier motivation analysis. Employing the conceptual framework offered by John Lynn and James McPherson, this thesis analyzes three components of the Eagles’ motivation—initial, sustaining, and combat.

Viewed in context, the Eagles’ decision to join a beleaguered air force reflected a commitment to ideological principles, as the desires to defend England and curb German aggression figured largely into their …

Chitosan Graphene Composite Fabrication And Characterization For Treatment Of Harmful Algal Blooms And Toxins, Sarah Zetterholm

Master's Theses

Chitosan graphene composites were fabricated and characterized as a management strategy for harmful algal blooms (HABs) caused by various species of cyanobacteria. These chitosan graphene materials were compared to previously studied chitosan graphene-oxide composites in both material properties and HAB treatment. In previous studies, adsorption of the cyanobacteria onto the surface of the composite materials has been observed. Investigations of the pure materials for these composites are also included in this study to determine whether removal is a result of charge interactions with the composite, or as an inherent property of the graphene or graphene oxide. Initial results suggest that …

Media Frames And Abortion Issue Polarization, Shianne Galuska

Master's Theses

The abortion issue is one of the most polarizing topics within the public and media sphere. How the media chooses to frame the abortion debate may influence public opinion and individual reactions. Specifically, articles that use incongruent abortion frames (pro-life/pro-abortion & anti-abortion/pro-choice) may be contributing to an ingroup versus outgroup mentality by highlighting who is the ingroup and who is the outgroup, thus generating moral disgust and polarization (characterized by anger, bias, and activism) amongst those with opposing views. This study sought to answer whether presenting individuals with an incongruent abortion frame increases anger, bias, and activism (polarization), as well …

Higher Command: An Examination Of African American Leadership In The Vietnam Era, Amanda Abulawi

Master's Theses

Since the founding of the United States, African Americans have sacrificed their lives to uphold the nation’s democratic ideals, all while being denied equal access to voting, education, employment, and housing rights at home.

The Role Of Notch1 And Notch3 In Adult Stem Cell Osteogenic Differentiation, John Bradley Cart

Master's Theses

Human adipose-derived stem cells (hASCs) have significant therapeutic potential due to their ability to self-renew, differentiate down multiple lineages, and modulate the immune system. In addition to these many benefits, hASCs boast a minimally invasive harvesting procedure, making them a readily available cell source for stem cell research and tissue regeneration (Ock, et al. 2016) (Abdi, et al. 2008). Despite their broad use, very little is known about the mechanisms that control cell fate.


One way to enhance our mechanistic understanding of differentiation is through the systematic examination of the signaling pathways. The Notch signaling pathway is a highly conserved, …

Mining Bitcoin To Avoid Sanctions, Tyler C. Lubin

Master's Theses

Though the world’s first cryptocurrency, Bitcoin, was introduced over a decade ago, it was not until recently that it became a mainstream subject. While cryptocurrencies offer many advantages, a potential downside for governments, is that no central bank controls the monetary policy and new coins can be mined by anyone anywhere in the world. Governments have always been deeply involved with how a their countries’ currency is ran and the policies they create are meant to keep a currencies’ value stable and make sure other factors like inflation is under control. Even though as of 2021, there were well over …
