Simulations Of Electrode Heterogeneity And Design For Lithium-Ion Batteries, Amir Sina Hamedi

Theses and Dissertations

This work develops three models for simulation of the high-current operation of Li-ion batteries. Simulation as a tool can provide understanding beyond what experiments can offer. Different types of electrodes such as graphite, silicon, and NMC are modeled to study cell performance and aging under aggressive operating conditions. The first part of this work focuses on the effect of electrode microscale lateral heterogeneity on the degradation of conventional Li-ion batteries, especially for fast-charge applications. The non-uniform pore distribution leads to the nonuniform current density and state of charge (SoC), which can finally result in non-uniform Li plating and aging. The …

Skew Relative Hadamard Difference Set Groups, Andrew Haviland

Theses and Dissertations

We study finite groups $G$ having a nontrivial subgroup $H$ and $D \subset G \setminus H$ such that (i) the multiset $\{ xy^{-1}:x,y \in D\}$ has every element that is not in $H$ occur the same number of times (such a $D$ is called a {\it relative difference set}); (ii) $G=D\cup D^{(-1)} \cup H$; (iii) $D \cap D^{(-1)} =\emptyset$. We show that $|H|=2$, that $H$ has to be normal, and that $G$ is a group with a single involution. We also show that $G$ cannot be abelian. We give examples of such groups, including certain dicyclic groups, by using results …

The Unburnt Offering: Mary As Co-Sacrifice In Early Sixteenth-Century Northern Birth Of The Virgin Images, Alexandra Carlile Butterfield

Theses and Dissertations

With the rising popularity of Mary's mother, St. Anne, Birth of the Virgin images proliferated at the beginning of the sixteenth century. However, these images have not been analyzed in great depth by any previous art historical scholarship. This thesis indicates the broader significance of these images by considering Birth of the Virgin compositions by Jan de Beer, Jacob Cornelisz van Oostsanen, and Adriaen van Overbeke. First, this thesis considers how these artists derived iconography from Robert Campin to connect Mary's nativity to the birth of her son. Thus, the artists invite the viewer to witness the significance and purity …

Resisting The Deficit Model: Embedding Writing Center Tutors During Peer Review In Writing-Intensive Courses, Stephanie B. Conner, Jennifer P. Gray

Journal of Response to Writing

For many students, peer review can be muddled or frustrating. They can feel uncomfortable with the process if they do not feel confident with their own writing, and many believe poor past performances disqualify them from offering constructive feedback. Because writing center tutors are trained in sharing feedback in a kind and helpful manner, they are positioned to be excellent models for students inexperienced with or damaged by feedback. Learning how to participate in effective peer review can remove the emotional baggage attached to writing and create a respectful community of writers in the classroom. In this teaching tip, we …

Written Corrective Feedback And Learner Engagement: A Case Study Of A French As A Second Language Program, Maria-Lourdes Lira-Gonzales, Antonella Valeo

Journal of Response to Writing

Within the context of second language (L2) writing, learner engagement with feedback has elicited significant theoretical and empirical interest (e.g., Zhang & Hyland, 2018; Zheng & Yu, 2018). Research has highlighted the dynamic nature of learner engagement with corrective feedback (WCF), but the ways in which learner and contextual factors impact such engagement with WCF in authentic classrooms are still underexplored (Han, 2019). Furthermore, little is known about how L2 learners engage with WCF from an ecological perspective, which considers the relationships between learners and their surrounding environments (Bronfenbrenner,1993; van Lier, 2000).

Designing Resilient Agents Using Grammatical Evolution, Behavior Trees, And Finite Linear Temporal Logic, Aadesh Neupane

Theses and Dissertations

Resilience is essential for long-term autonomous agents. Swarm behaviors seen in bees, ants, birds, fish, and others are interesting because they resiliently perform complex coordinated tasks like foraging, nest-selection, flocking and escaping predators without centralized control or coordination. Conventionally, mimicking swarm behaviors with robots requires researchers to study actual behaviors, derive mathematical models, and implement these models as state machines. Since the conventional approach is time-consuming and cumbersome, this dissertation uses a grammatical evolution algorithm with Behavior Trees (BTs) to evolve behaviors that are resilient to different perturbations for foraging and nest maintenance tasks. The modular, reactive, and readable properties …

Toward Automatically Composed Fpga-Optimized Robotic Systems Using High-Level Synthesis, Szu-Wei Lin

Theses and Dissertations

Robotic systems are known to be computationally intensive. To improve performance, developers tend to implement custom robotic algorithms in hardware. However, a full robotic system typically consists of many interconnected algorithmic components that can easily max-out FPGA resources, thus requiring the designer to adjust each algorithm design for each new robotic systems in order to meet specific systems requirements and limited resources. Furthermore, manual development of digital circuitry using a hardware description language (HDL) such as verilog or VHDL, is error-prone, time consuming, and often takes months or years to develop and verify. Recent developments in high-level synthesis (HLS), enable …

Permanent Passive Fire Protection Against Wildland-Urban Interface Fires, Makenzie Wilson

Theses and Dissertations

The average intensity and frequency of wildland fires have been on the rise over the years, leading to an increase in the risk to homes located in the Wildland-Urban Interface (WUI). Fire suppression is the most used method of wildland fire control, but this suppression can cause wildland fires to become more frequent and devastating. Increased development in the WUI also puts these homes at greater risk. Current methods of passive fire protection are effective, but these methods are expensive, time consuming to set up, and not fully effective. This research proposes a permanent passive fire protection system that is …

Theses and Dissertations

Recent literature on the relationship between instructional designers (IDs) and subject matter experts (SMEs) reveals how much more is known about the challenges faced by IDs and more solutions are offered in their respective role compared to their SME partners. This study uses interpretative phenomenological analysis (IPA) to investigate the ID-SME collaborative relationship from the perspective of and the utility for the SME role within the field of Technology and Innovation Management (TIM). Six SMEs within the field of TIM were interviewed to discover more on the nature of their working relationship, specifically in regard to (a) their conceptual understanding …

Long-Term Modulus Of Microcracked Cement-Treated Base Layers, Patrick Matthew Mcdivitt

Theses and Dissertations

The objective of this research was to measure and analyze the long-term modulus values of cement-treated base (CTB) layers constructed in Utah using microcracking. Because modulus values of pavement layers are among the most influential inputs affecting mechanistic-empirical pavement design, obtaining reasonable estimates of modulus values is critical. Testing was performed with a portable falling-weight deflectometer, also called a lightweight deflectometer, and modulus values were backcalculated with the computer program BAKFAA. Testing occurred at five asphalt pavement sites in northern Utah, where reconstruction with full-depth reclamation and cement stabilization, in the form of cement slurry, was performed approximately 2 to …

The Naci Way: Connecting Native Groups And Teachers Through Culturally Responsive Instructional Design, Stephanie West, Heather Francis, Cally Flox, Brenda Beyal, Emily Soderborg, Jason Mcdonald

Instructional Psychology and Technology Graduate Student Projects

In 2018, the BYU ARTS Partnership Native American Curriculum Initiative (NACI) was developed in response to teacher questions regarding the teaching of Native topics. Despite increased movements towards reconciliation, Native groups continue to be marginalized in Westernized educational settings. Additionally, teachers lack clear guidelines regarding the respectful teaching of Native topics. Describing the challenges we, the NACI team members, faced in our four-year journey partnering with Native groups in Utah, we outline key instructional design decisions we made and identify the culturally responsive principles that guided those decisions. We also advocate for the application of culturally responsive principles and practices …

Mazar's Modified Chronology: The Preservation Of Solomonic Possibilities, Aaron By Gorner

Student Works

In the polarized, post-enlightenment world of biblical studies, there is a need for measured approaches to scholarly debate which hold ample room for all possible realities. The timeline of the "Solomonic" gates at Tel-Megiddo has been debated for years, with Yiguel Yadin's conventional foundation coming into conflict with newer, more critical approaches such as Isreal Finkelstein's "Low Chronology". In this paper, it will be argued that in the polarized wreckage, Amihai Mazar and his "Modified Conventional Chronology" preserve the necessary lack of conclusion that current ambiguities call for. His work demonstrates that many explicit conclusions which polarize the debate are …

Dopamine D2 Receptors As A Peripheral Biomarker For Brain Dopamine Levels, Christina Small

Theses and Dissertations

The ability to objectively index dopamine (DA) levels in the brain has the potential to revolutionize the field of neuropsychopharmacology, as having a peripheral biomarker of brain DA would enable the objective monitoring of the progression of Parkinson's disease (PD) and other DA-dependent psychiatric states. Of particular relevance to commercialization, it would provide an objective measure of treatment efficacy. We used a DA-depletion approach to determine if peripheral D2Rs are a biomarker for brain DA; mainly, the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) neurotoxin model and PD subjects, which are well-known models of DA depletion in the midbrain of rodents and humans, respectively. Dopamine …

The COVID-19 pandemic offered an unprecedented opportunity to study teachers' experiences as they are required to navigate new literacies while teaching online. Therefore, the purpose of this phenomenological study was to explore the lived experience of three upper elementary school teachers as they navigated the use of new literacies in a Title I school during a global pandemic. Data sources included three in-depth interviews and were analyzed through a thematic approach. Data analysis resulted in identifying …

New Perspectives On Foot Segment Forces And Joint Kinetics - Integrating Plantar Shear Stresses And Pressures With Multi-Segment Foot Modeling, Dustin A. Bruening, Spencer R. Petersen, Sarah T. Ridge

Faculty Publications

The role of the foot in gait is not well understood, in part due to challenges in capturing and utilizing segmental ground reaction forces. The purposes of this study were to 1) develop methodology to integrate plantar pressure/shear stresses with a multi-segment foot model, and 2) generate and display key normative data from this combined system. Twenty-six young healthy adults walked barefoot (1.3 m/s) across a pressure/shear sensor with markers matching a published 4-segment kinetic foot model. A novel anatomical/geometric masking method was developed that successfully separated regions aligned with model segmentation. This template-based method can be automated and customized …

Validation And Development Of Top-Down Illumination For Optofluidic Biosensors, Matthew Marley Hamblin

Theses and Dissertations

Lab-on-a-chip devices are changing the way that medical testing is performed by allowing rapid testing with small samples. Optofluidic biosensors are a type of lab-on-a-chip device that use light excitation on a fluid sample. One such application of an optofluidic biosensor is a device that can detect antibiotic resistant bacteria by combining DNA from a sample with fluorescent beads, flowing that sample through a hollow channel, and shining laser light on the channel. If the bacteria tested for is present, the fluorescent beads will give off photons that can be detected as a positive signal. The main method for illumination …

Body In Rebellion: The Closing Body, Romantic Mesmerism, And Gothic Doubles In Hogg's Justified Sinner, Elizabeth E. Hinds

Theses and Dissertations

This study explores the western Romantic period as a transition between the medieval “open body” and the modern “closed body.” It focuses on “closing body” phenomena such as “mesmerism” (i.e. animal magnetism), somnambulism, substance abuse, and the “second-self,” including notions of the subconscious and the trope of gothic Doppelgängers. This study draws from many pieces of western Romantic literature but is most centered around James Hogg’s 1824 The Private Memoirs and Confessions of a Justified Sinner. This new reading of Hogg’s novel suggests a core theme of body anxiety, rather than theological dispute.
