Polybenzimidazole Membranes For Electrochemical Applications With Harsh Operating Conditions, Kris Likit-Anurak
Theses and Dissertations
Polybenzimidazole (PBI) membranes are high temperature proton exchange membranes (PEMs) which have advantages such as being able to operate in high temperatures, strong acid environments, and have no need for external humidity during operation. PBI membranes have been demonstrated to work effectively in multiple electrochemical devices, including fuel cells, hydrogen separation pumps, redox flow batteries, and a hybrid sulfur electrolyzer. In this work, para-PBI and densified para-PBI membrane have been used to improve electrochemical performance in harsh operating conditions that are both high temperature (≥120 ̊C) and high acid concentration (≥ 5M). First, we demonstrated the use of para-PBI membranes …
Floodplain And In-Channel Sedimentation In The Bedrock Congaree River, Sc, Mahsa Ahmadpoor
Floodplain And In-Channel Sedimentation In The Bedrock Congaree River, Sc, Mahsa Ahmadpoor
Theses and Dissertations
The Congaree River planform is characterized by an abrupt increase in channel sinuosity in the downstream direction. Such a change is not typical of alluvial meandering rivers but has been observed in mixed bedrock-alluvial rivers. This motivated the first study of this dissertation, specifically designed to determine if the Congaree River is indeed a mixed bedrock-alluvial river in its low sinuosity (upstream) reach. To test this hypothesis, sonar-based measurements of channel bed and sublayer elevation were performed from Columbia to the Congaree River-Wateree River confluence. The sublayer is here defined as the first surface visible in the sonar measurements underneath …
The Effect Of Instructionally Embedded Cognitive Reframing On Students’ Self-Beliefs Of Their Mathematical Competence, Kelly Eyre Frazee
The Effect Of Instructionally Embedded Cognitive Reframing On Students’ Self-Beliefs Of Their Mathematical Competence, Kelly Eyre Frazee
Theses and Dissertations
Many students lack the ability to maintain positive perceptions of their mathematical self-belief, resulting in undesirable social, emotional, and academic outcomes. The purpose of this study was to investigate the impact of a cognitive reframing strategy on third and fourth grade math intervention students’ perceptions of their mathematical competence. This study sought to understand the impact of this emotional regulation strategy on students’ ability to autonomously regulate their negative or irrational thoughts related to their mathematics abilities, as well as the impact on their self-beliefs. Data for this study were collected through semi-structured interviews with students, student reflections, and researcher …
A Globalized Optimization Schema For Automated Fiber Placement Processing Parameters, Matthew John Godbold
A Globalized Optimization Schema For Automated Fiber Placement Processing Parameters, Matthew John Godbold
Theses and Dissertations
Automated Fiber Placement is an advanced manufacturing technique for industrial-scale composite structures. Advanced robotics coupled with composite manufacturing results in faster and more consistent results than previously obtained through hand layup. The complexity and interconnectedness of the automated fiber placement process provides a difficult challenge for traditional modeling techniques. Modeling within automated fiber placement currently utilizes physics-based modeling to inform the translation of a design to a manufacturing plan. The intricacy of the automated fiber placement process dictates that attempts at modeling or optimizing these processes are often limited in their scope. Physics-based modeling for manufacturing typically involves numerous interacting …
Causes And Consequences Of The Risk Of Generalizability Biases In Health Behavioral Interventions, Lauren Von Klinggraeff
Causes And Consequences Of The Risk Of Generalizability Biases In Health Behavioral Interventions, Lauren Von Klinggraeff
Theses and Dissertations
Preliminary testing of health behavior interventions (e.g., pilot, feasibility studies) are used to evaluate intervention viability prior to additional testing and resource investment (e.g., larger trials). This initial testing provides valuable information, but promising estimates of effectiveness produced during early testing are rarely reproduced in larger studies, stalling the development of effective, scalable health interventions. In the obesity intervention literature, external validity biases, features of the intervention that are not (or cannot) transfer to the larger study, are associated with these diminished effects. These study features, such who delivers the intervention, the characteristics of the population receiving the intervention or …
Adapting Deep Learning Techniques For Geologic Investigations Of Hydrothermal Venting At Seafloor Spreading Ridges Using Auv Surveys, Isaac Keohane
Adapting Deep Learning Techniques For Geologic Investigations Of Hydrothermal Venting At Seafloor Spreading Ridges Using Auv Surveys, Isaac Keohane
Theses and Dissertations
Locating hydrothermal chimney sites unlocks research into their correlations with geology, lithospheric cooling, and deep-sea biogeography at seafloor spreading ridges. High-resolution bathymetry and sidescan sonar collected by Automated Underwater Vehicles allows for chimneys, only a few meters wide and tall, and fissures, only a few meters wide, to be resolved across large areas (>100 km2). We developed a Chimney Identification Tool (CIT) that utilizes a Convolutional Neural Network (CNN), a Machine-Learning model able to classify based on shapes and textures, to identify chimneys in 1m-gridded bathymetry. We then utilized the CIT to identify many potential off-axis chimney structures at …

Computerized Psychological Testing: Designing And Developing An Efficient Test Suite Using Hci And Reinforcement Learning Techniques, William Henry Hoskins
Theses and Dissertations
In this work we discuss the design and development of the Carolina Automated Reading Evaluation (CARE), created to facilitate the finding of deficits in the reading ability of children from four to nine years of age. Designed to automate the process of screening for reading deficits, the CARE is an interactive computer-based tool that helps eliminate the need for one-on-one evaluations of pupils to detect dyslexia and other reading deficits and facilitates the creation of new reading tests within the platform. While other tests collect specific data points in order to determine whether a pupil has dyslexia, they typically focus …

Learning Through Business Unit Failure: A Study Of Individuals And Mid-Level Managers, Corinna Calhoun
Theses and Dissertations
Research on business failure focuses primarily on entrepreneurs and largely ignores individuals and mid-level managers who comprise most corporate populations. This study aimed to mitigate this gap by exploring how 15 individuals and mid-level managers working in a Fortune 50 technology company experienced failure and how their beliefs impacted their experience and learnings. Qualitative interview data were analyzed using a schema from the literature. The results suggested that emotional regulation, belief in personal agency, and separation of self from work supported learning and positive outcomes. Future research would create deeper insights into the social impacts on emotions and sensemaking and …
An Examination Of Student’S Motivation To Learn In Higher Education: A Study Of Contributing Factors To Undergraduate Students’ Motivation, Aida Jafari
Theses and Dissertations
Motivation is a complicated concept and difficult to measure and study; nevertheless, it is a substantial factor in students’ performance that demands extra attention. Instructors across all grade levels and disciplines struggle to cultivate classroom environments that focus on student interactions and promote interest where high-quality work is produced (Middleton & Perks, 2014). Educators have been searching for new strategies to improve instruction and student learning, and they keep looking for new ways to increase student motivation (Middleton & Perks, 2014). Moreover, practical knowledge in the classroom depends on the instructor’s ability to stimulate the interest and motivation that brought …

Best Practices Of Virtual Learning For K-5 Students, Bailey Hooper
Theses and Dissertations
With the increase in technology, virtual learning programs continue to grow in popularity within the United States. Before the coronavirus (COVID-19) pandemic, the kindergarten through fifth grade (K-5) virtual learning population has increased each year slowly since the late 1900s. However, due to the COVID-19 pandemic millions of K-5 students were engaged in virtual learning. However, the academic outcomes and learning loss that resulted from the school shutdowns caused many misconceptions regarding the educational and social developments of K-5 students enrolled in virtual classes. Yet, studies consistently prove synchronous virtual instruction can be as effective as traditional face-to-face learning. The …
