The Evolution Of X-Ray Binaries And Their Accretion States, Lacey A. West Dec 2022

The Evolution Of X-Ray Binaries And Their Accretion States, Lacey A. West

Graduate Theses and Dissertations

X-ray binary systems (XRBs) consist of a compact object component (e.g., black hole or neutron star) that accretes matter from a companion star. Although the extent to which XRBs contributed to the early heating of the intergalactic medium is still under investigation, it is estimated that XRBs dominated the X-ray radiation field before the reionization epoch. The study of XRB emission is therefore crucial to our understanding of the very early universe. Furthermore, studying the abundance and radial distribution of each XRB type within a galaxy can be revealing of the host galaxy’s local properties, structure, and evolution. XRB spectra …


Scarico: It’S Only A Movie, Most Of The Time, Thomas Nelson Dec 2022

Scarico: It’S Only A Movie, Most Of The Time, Thomas Nelson

Graduate Theses and Dissertations

Exploitation cinema is a domain of motion picture content catering to a viewership interested in imagery that is more provocative than what mainstream audiences desire to see. These types of films are typically considered lowbrow entertainment and have been made in every era, albeit in a limited capacity proportional to the niche audience demand for them. Some time periods see a rise in exploitation film productions in response to a growing demand for such content from a larger share of the broader cinematic audience. This relationship indicates that period-specific cultural factors can cause mainstream audience members to seek out more …


Movie Reviews Sentiment Analysis Using Bert, Gibson Nkhata Dec 2022

Movie Reviews Sentiment Analysis Using Bert, Gibson Nkhata

Graduate Theses and Dissertations

Sentiment analysis (SA) or opinion mining is analysis of emotions and opinions from texts. It is one of the active research areas in Natural Language Processing (NLP). Various approaches have been deployed in the literature to address the problem. These techniques devise complex and sophisticated frameworks in order to attain optimal accuracy with their focus on polarity classification or binary classification. In this paper, we aim to fine-tune BERT in a simple but robust approach for movie reviews sentiment analysis to provide better accuracy than state-of-the-art (SOTA) methods. We start by conducting sentiment classification for every review, followed by computing …

Simulating Emergency Evacuation Response In An Auditorium Space, Anna Lee Dec 2022

Simulating Emergency Evacuation Response In An Auditorium Space, Anna Lee

Industrial Engineering Undergraduate Honors Theses

The successful execution of emergency evacuations is very important for the protection of the public. Some emergency events, such as fires, can occur with very little warning and turn into a dangerous situation in less than a minute. With high population densities, universities have increased risk involved with evacuations. One specific area that presents high risk is auditorium spaces such as lecture halls with high densities combined with added barriers such as tables and chairs. The ability to assess a building’s emergency preparedness is necessary for keeping the public safe. Simulation is a way to conduct a theoretical event and …

Instance Segmentation-Based Depth Completion Using Sensor Fusion And Adaptive Clustering For Autonomous Vehicle Perception, Mohammad Z. El-Yabroudi

Dissertations

Depth sensing is critical for safe and accurate maneuvering in robotics and self-driving car (SDC) applications. Most recent LiDAR sensors, such as Ouster and Velodyne, offer 360 degrees of scanning at the rate of ten frames per second, making them very appropriate for autonomous driving applications. However, LiDAR point cloud data show many shortcomings, especially its data sparsity and unassigned nature, making it very challenging to utilize in applications such as perception, 3D object detection, 3D scene reconstruction, and simultaneous localization and mapping.

In this study, a novel framework using instance image segmentation and the raw LiDAR data for the …


A Framework For Assessing The 4th Rank Dispersivity Tensor Under Anisotropic Axial Symmetries, Xiang Fan Dec 2022

A Framework For Assessing The 4th Rank Dispersivity Tensor Under Anisotropic Axial Symmetries, Xiang Fan

Dissertations

Multi-dimensional expansion of the advection-dispersion equation necessitated the representation of dispersivity as a 4th rank tensor. This tensorial form of dispersivity has 81 terms in three-dimensions with a maximum of 36 independent terms that may be used to describe Fickian spreading of a dissolved contaminant plume according to intrinsic properties of a porous medium. The complexity of the 4th rank tensor has led to the common practice of simplifying the tensor to only 2 or 3 independent terms by assuming isotropic conditions, although isotropic porous media are uncommon in nature as many natural geologic systems exhibit pronounced anisotropy. A broad …

Universal Pre-K In Comstock Public Schools, Meadow A. Nuyen Dec 2022

Universal Pre-K In Comstock Public Schools, Meadow A. Nuyen

Dissertations

In 1971, President Nixon vetoed legislation that would have created federal funding for the education of kids under age five. With the veto, President Nixon reaffirmed that, except for poor children, the education and care of the children is the responsibility of the family, not the government. Yet over 31 years later, 41 states and the District of Columbia provide state-funded preschool (Waxman, 2021). Preschool in the state of Michigan is not automatically provided as K-12 education is. This study examined the beliefs of staff in Comstock Public Schools regarding Universal Pre-K, tuition-free preschool for all 4-year-olds. Participants included district …

Making Mandates Last: Increasing Female Representation On Corporate Boards In The U.S., Nikki Williams Dec 2022

Making Mandates Last: Increasing Female Representation On Corporate Boards In The U.S., Nikki Williams

Michigan Journal of Gender & Law

A lack of female representation on corporate boards has plagued our country for decades. Until a few years ago, there was not a single state or federal regulation that required corporations to fill board seats with female directors. Instead, the federal government talked around the issue. In 2010, the SEC established an optional reporting structure for corporations to communicate their hiring practices, but did little else. With no national plan in place, many states implemented legislation that urged corporations to hire female directors. But this legislation barely moved the needle. The country needed a mandate. And in 2018, California implemented …


Character Spotting And Autonomous Tagging: Offline Handwriting Recognition For Bangla, Korean And Other Alphabetic Scripts, Nishatul Majid, Elisa H. Barney Smith Dec 2022

Character Spotting And Autonomous Tagging: Offline Handwriting Recognition For Bangla, Korean And Other Alphabetic Scripts, Nishatul Majid, Elisa H. Barney Smith

Electrical and Computer Engineering Faculty Publications and Presentations

This paper demonstrates a framework for offline handwriting recognition using character spotting and autonomous tagging which works for any alphabetic script. Character spotting builds on the idea of object detection to find character elements in unsegmented word images. An autonomous tagging approach is introduced which automates the production of a character image training set by estimating character locations in a word based on typical character size. Although scripts can vary vividly from each other, our proposed approach provides a simple and powerful workflow for unconstrained offline recognition that should work for any alphabetic script with few adjustments. Here we demonstrate …

Student And Teacher Perspectives On Asynchronous Learning During The Covid Pandemic, Michele Ehrhart Dec 2022

Student And Teacher Perspectives On Asynchronous Learning During The Covid Pandemic, Michele Ehrhart

Education Doctorate Dissertations

The COVID Pandemic shut down schools across the country, leaving K-12 schools unprepared for virtual learning. In this mixed methods study, I examined data gathered from my 8th-grade science classes to assess the effectiveness of asynchronous instruction. My original research question was: How much if at all, did learning outcomes differ as a function of how the lessons were taught (uninterrupted instructional video versus interrupted/interactive Edpuzzle video)? Based on a preliminary examination of data, my study expanded into how self-regulated learning affected students’ comprehension, interest, and motivation. Study results showed no statistical differences in students’ comprehension based on how lessons …

Energy Storage Capacity Determination For Agc Frequency Modulation In The Power System With Wind And Photovoltaic Power Based On The Stochastic Simulation And Emd, Haijing Yang, Yufei Rao, Chaohui Li, Xin Sun

Journal of Electric Power Science and Technology

With the deep penetration of wind and photovoltaic power, the moment of inertia in the power system is reduced, resulting in the problem of frequency modulation for the automatic generation control of the power system. Energy storage is widely applied in the frequency modulation of power systems due to its fast reaction and accuracy. As a result, random simulation and empirical mode decomposition are combined to propose an energy storage capacity determination method in automatic generation control. Firstly, the empirical mode decomposition is utilized to decompose the regional control deviation into the high-frequency and low-frequency components. The energy storage frequency …

Philosophers Of Catastrophe: Early 20th Century Jewish Proponents And Opponents Of Objectivity In Science, Steven Gimbel, Stephen J. Stern

Philosophy Faculty Publications

The Second World War ended with the exposure of the Nazi death camps and the threat of global nuclear annihilation. The former disclosed the depths of human depravity and the latter warned us about the severity of the consequences that could await us as a result. The grimness of each, much less both, had the effect of shielding from our collective consciousness the equally dire warnings from the First World War that had occurred only a couple of decades earlier.
