Data-Driven Modeling And Vibration Control Of Rotary Systems, Sina Piramoon

Engineering Ph.D. Theses

This Ph.D. thesis presents an integrated approach to mitigating lateral vibrations in vertical shaft rotary machines during transient responses by combining physics-based and data-driven methodologies. Two primary strategies are explored and validated through experimental studies on a laboratory test rig.

The research introduces a novel method that integrates Sparse Identification of Nonlinear Dynamical Systems (SINDy) with a physics-based approach to accurately reconstruct the governing nonlinear equations of vertical-shaft rotary machines. An extensive mathematical library supports this reconstruction, which underpins the design of a nonlinear controller using terminal sliding mode control (TSMC). This control technique effectively reduces lateral vibrations, ensuring the …

The Difference In Fitness And Lower Body Power Based On Mobility Status In First Responders, Serena Paterno

Senior Honors Projects

First responders have physically demanding jobs with an increased risk of injury. Previous research has shown that asymmetry of mobility and stability in the lower extremity is associated with an increased risk of lower extremity injuries, while increased fitness and lower body power are associated with a reduced risk of injury. However, there is limited research examining the relationship between lower limb asymmetry, fitness, and lower body power output in first responders.

Netflix Originals Performing The Private Lives Of Marginalized Communities For A Global Audience, Kirk Kanesaka

World Languages and Literatures Faculty Publications

The Western fascination with geisha began with the travels of Sadayakko (1871–1946) and Hanako (Ōhta Hisa, 1868–1945), the first geisha to perform overseas in the United States and Europe. Hanako’s captivating face inspired Auguste Rodin (1840–1917) to sculpt her numerous times, making her the only Asian he ever depicted. To Rodin, she symbolized Asian beauty and mystery, leading to her Orientalization. Early photographs of Japanese individuals sent to the West, often featuring geisha and kabuki actors, further fueled Western interest in geisha.

The West’s initial encounters with geisha were not part of the Meiji government’s official narrative. Sadayakko, often overlooked …

An Analysis Of Themes In East German Films Between 1946 And 1974, Audrey Hopper

2024 Awards for Excellence in Student Research and Creative Activity - Documents

Historians have studied the history of the divided Germany. Many of these historians have studied the nuances that appear when comparing the German Democratic Republic and the Federal Republic of Germany. Historians have debated on which of the Cold War era Germanys created the best response to the Nazi past during World War II. Philosopher Sarah Neiman weighs in on the debate and takes her spin on the topic. Her book focuses on the concept that countries like the United States should learn from Germany, as the country has been reconciling its past on a national level, which is something …

2024 Awards for Excellence in Student Research and Creative Activity - Documents

The Supplemental Nutrition Assistance Program, or SNAP, is one of the most important welfare programs the United States government offers. In fiscal year 2015, one in every seven Americans received SNAP assistance. Previously called food stamps as they were first introduced with the passing of the Food and Agriculture Act in 1977, this program has been helping individuals struggling with food insecurity for decades (Ziliak 2016). Benefits are no longer dispersed with physical stamps, restricting what households can and cannot buy. Now benefits are distributed via a debit card-type system. This is where the EBT gets added to the program …

Anthropodenial And The Human/Animal Divide In The Island Of Dr. Moreau, Kimiko Clark

Undergraduate Review

Animal experimentation, also called vivisection, has been a controversial conversation topic in both the scientific world and the animal rights activism world. While one of the main arguments regarding animal experimentation is whether or not animals have the right to bodily autonomy, a lesser discussed topic within the realm of animal experimentation is what it reveals about humans. From Charles Darwin’s theory of evolution to current scientists expanding knowledge about animal bodies, the line separating humans and animals has been blurred.

Beyond Combat: Moral Injury Exposure In Officer And Enlisted Marine Veterans With Diverse Deployment Histories And The Relationship With Posttraumatic Growth, Hira Jean Byrne Paulin

Graduate Research Theses & Dissertations

Moral injury has been widely studied in male combat-deployed active-duty personnel and veterans, with little inclusion of non-combat or never-deployed experiences. Moral injury research has primarily focused on adverse outcomes. Within military moral injury research, there is limited information on individual branches of service or rank-specific experiences. The purpose of this study was to explore moral injury event exposure and posttraumatic growth within a single branch of service, the Marine Corps, with a focus on rank status and the inclusion of non-combat and never-deployed veterans. A community-based approach was used to recruit participants over a 2-month period. Participants completed a …

Academic Motivation Of African American Male Students At Indiana State University, Nathan Harris

All-Inclusive List of Electronic Theses and Dissertations

African American student academic performance is a topic of much concern in the U.S. (Allen, 1992; Cokley, 2000, 2002, 2003; Cokley & Moore, 2007; Cokley et al., 2015; Harper et al., 2012; Harper, 2015; Steele, 1992). Thus, the task of closing the academic achievement gap between Black and White students is a worthy assignment undertaken by many researchers. The purpose of this study is to perform a qualitative inquiry to learn more about the African American male psychological motivation of self-esteem, racial identity, and academic self-concept. Literature about African American student self-esteem and self-concept exists yet based on my observations, …

A Limit Order Book Model For High Frequency Trading With Rough Volatility, Yun S. Chen-Shue

Graduate Thesis and Dissertation 2023-2024

We introduce a financial model for limit order book with two main features: First, the limit orders and market orders for the given asset both appear and interact with each other. Second, the high frequency trading (HFT, for short) activities are allowed and described by the scaling limit of nearly-unstable multi-dimensional Hawkes processes with power law decay. The model eventually becomes a stochastic partial differential equation (SPDE, for short) with the diffusion coefficient determined by a Volterra integral equation governed by a Hawkes process, whose Hurst exponent is less than 1/2, which makes the volatility path of the stochastic PDE …

The Dyslexic Actor: How Dyslexia Affects The Acting Process, Kate Milazzo

Graduate Thesis and Dissertation 2023-2024

Dyslexia can benefit an actor, especially if the individual is aware of how the challenges and advantages of dyslexia impact their personal acting process. Dyslexia is widely understood to be a learning disability that affects an individual's reading and writing abilities. Many forms of theater rely on the written word, and an actor's success lies in their ability to interpret the text, leading one to question whether a dyslexic individual can find success as an actor. Yet several famous actors, including Octavia Spencer and Henry Winkler, are known to be dyslexic. As a dyslexic individual, I have also successfully participated …

Antimicrobial Activity Of Gallium(Iii) Compounds: Pathogen-Dependent Targeting Of Multiple Iron/Heme-Dependent Biological Processes, Seoung-Ryoung Choi, Mohammed A. Hassan, Bradley E. Britigan, Prabagaran Narayanasamy

Journal Articles: Pathology and Microbiology

Metals play vital roles in biological systems, with iron/heme being essential for cellular and metabolic functions necessary for survival and/or virulence in many bacterial pathogens. Given the rise of bacterial resistance to current antibiotics, there is an urgent need for the development of non-toxic and novel antibiotics that do not contribute to resistance to other antibiotics. Gallium, which mimics iron, has emerged as a promising antimicrobial agent, offering a novel approach to combat bacterial infections. Gallium does not have any known functions in biological systems. Gallium exerts its effects primarily by replacing iron in redox enzymes, effectively inhibiting bacterial growth …

The Impact Of Local Physiology On The Corrosion Of Orthopedic Alloys, Madison Nicole Brown

Theses and Dissertations (ETD)

Introduction. Total knee arthroplasty (TKA) is used in the treatment of end-stage osteoarthritis of the knee. It is one of the most common elective surgeries performed with predictions expecting significant increases in the number of procedures performed over the next decade. However, the patient satisfaction rate after TKA is as low as 80%. Cobalt-chromium-molybdenum (CoCrMo) is regularly used for TKA protheses due to the alloy’s mechanical strength, biocompatibility, and corrosion resistance. The corrosion resistance of this alloy relies on a passive oxide layer. This oxide layer can be impacted by phagocytic cells which can leave pits and craters on implant …

Exploring The Effects Of Interviewer Body Language Availability During A Videoconference Behavioral Health Interview, Efthymia Orkopoulou

Master's Theses and Doctoral Dissertations

This experiment sought to explore whether an interviewer’s body language availability would have any effects on participants’ interactional engagement levels, positivity-negativity of interaction, and their nonverbal synchrony. Six participants answered questions about their well-being during a Zoom interview. Participants were exposed to three Near and three Far video framing conditions alternating every 10 min. Results showed that body language availability did not have reliable effects on the examined nonverbal communication indices. Time, however, did have some significant and close-to-significant effects on certain variables. Treatment reversal graphs showed that body language availability may reliably impact some participants’ responding. However, the rarity …
