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 …

Real-Time Prediction-Driven Dynamics Simulation To Mitigate Frame Time Variation, Mackinnon A. Buck

Master's Theses

Real-time physics engines have seen recent performance improvements through techniques like hardware acceleration and artificial intelligence. However, state of the art physics simulation technology fails to account for the variation in simulation complexity over time. Sudden increases in contact frequency between simulated bodies can momentarily increase the processing time per frame. To solve this, we present a prediction-driven real-time dynamics method that uses a memory-efficient graph-based state buffer to minimize the cost of mispredictions. This buffer, which is generated by a separate thread running the physics pipeline, allows physics computation to temporarily run slower than real-time without affecting the frame …

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 …

Indoor Positioning Using Synchronized Ultrasonic Ofdma Signals, Julian Bartolone

Master's Theses

This paper proposes a method of short-range indoor localization using differential phase measurements of synchronized two-tone ultrasonic signals in an Orthogonal Frequency Multiple Access (OFDMA) scheme. This indoor positioning system (IPS) operates at an ultrasonic frequency of approximately 40kHz and synchronizes using an infrared signal. The OFDMA scheme allows for a receiver to process the signals from multiple transmitters continuously without the signals interfering with each other. The phases of the signals are measured using Goertzel Filters, allowing for low-complexity frequency content analysis. A MATLAB simulation using the proposed localization method is performed using four transmitter nodes in the corners …

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 …

Multi-Valued Solutions For The Equation Of Motion, Darcy-Jordan Model, As A Cauchy Problem: A Shocking Event, Chandler Shimp

Shocks are physical phenomenon that occur quite often around us. In this thesis we examine the occurrence of shocks in finite amplitude acoustic waves from a numerical perspective. These waves, or jump discontinuities, yield ill-behaved solutions when solved numerically. This study takes on the challenge of finding both single- and multi-valued solutions.

The previously unsolved problem in this study is the representation of the Equation of Motion (EoM) in the form of the Darcy-Jordan model (DJM) and expressed as a dimensionless IVP Cauchy problem. Prior attempts to solve have resulted only in implicit solutions or explicit solutions with certain initial …

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 …

Extinction Coefficient Measurement Comparison Of Tungsten Powder Clouds, Spencer P. Grenley

Master's Theses

All materials in dust form pose an increased risk of accidental deflagration, or explosion. For workplace safety, this risk of deflagration for a solid particulate sample is characterized through specialized dust explosibility testing systems. These systems disperse a cloud of powder inside a spherical chamber via a pressure gradient, where a timed ignition occurs. The accuracy of measurements taken during this process are predicated upon the assumption that the cloud of powder is uniformly distributed during the ignition period. Metal additive manufacturing (AM) is a rapidly expanding technology that, in some cases, involves heavy metal powders that do not disperse …

Optimization Of Interplanetary Transfer Trajectories Using The Invariant Manifolds Of Halo Orbits, Ryan Yedinak

Master's Theses

Traditionally, two-body dynamics have been used to design orbital trajectories for interplanetary missions using a series of Lambert’s transfers and gravity assists. Although these are reliable methods, they have extremely high fuel requirements, especially for missions to outer planets. From an orbital mechanics perspective, three ways of reducing fuel requirements for these types of missions are utilizing low energy transfer trajectories, applying low thrust engine parameters, and implementing orbit optimization techniques.

The goal of this thesis is to combine low energy transfers created from the dynamics of the Circular Restricted Three-Body Problem (CRTBP) with low-thrust orbit optimization techniques to develop …

An Examination Of The Fuzzy Inference System On Probabilistic Roadmap Path Planning, Brandon Replogle

Master's Theses

In recent years, multi-robot systems have been widely used in many applications such as warehouse inventory tracking and automatic search and rescue operations. Probability roadmap (PRM) is a typical path planning algorithm that can determine an optimal trajectory once the robot start and goal positions are specified. However, when the number of robots in the system increases, it converges slowly and may even fail to find the solution.

In this thesis, a fuzzy inference system is proposed and combined with the probability roadmap algorithm for robot path planning. Computer simulation results in five different environments show this approach is very …
