Recognizing The Role Of Rhetoric In Secondary Writing Groups, Catherine Schrecengost Jun 2024

Recognizing The Role Of Rhetoric In Secondary Writing Groups, Catherine Schrecengost

Theses and Dissertations

This project seeks to mediate one of the most significant issues with implementing writing groups in the secondary classroom: students do not know how to meaningfully engage in discussions about their writing. Students lack the necessary skills as well as understanding of the rhetorical nature of language to effectively request and provide feedback on pieces of writing. The application of theories of dialogue and collaboration to the research about writing groups suggest that the quality of student writing depends on the quality of their discussions about writing. Thus, my action research study investigates the types of language used between students …


Understanding The Mechanical And Electrochemical Impacts Of Binder Systems On Silicon Anodes In Lithium-Ion Batteries, Fei Sun Jun 2024

Understanding The Mechanical And Electrochemical Impacts Of Binder Systems On Silicon Anodes In Lithium-Ion Batteries, Fei Sun

Theses and Dissertations

Silicon has emerged as a promising alternative to traditional graphite as an anode material in battery technology, primarily due to its high theoretical capacity and abundance. However, its application is hindered by significant challenges, including severe volume expansion in the active material (~275%) during cycling, which can lead to a series of electrode failure issues. Polymer binder plays an essential role in addressing these challenges as it accommodates silicon's volume expansion and the rearrangement of particles. This work conducted an analysis of how different binders influence mechanical and electrochemical properties of silicon electrodes. Our findings are supported by a series …

"Vampire Plastics": An Investigation Of Poly(Olefin Sulfone) Depolymerization And Its Dust Mitigation Abilities, Alexandra Kathryn Kanani Gallion Stapley

Theses and Dissertations

The ubiquity of particulate contamination requires dust mitigation techniques to provide low-scatter surfaces and edges on sensitive optical devices in space. Poly(olefin sulfone)s have been shown to photodegrade with the assistance of a photobase generator when exposed to UV light (254 nm) and heat (120 °C). These polymers may be useful for minimizing dust on optical surfaces for space applications. However, their behavior in vacuum has not been fully characterized. We synthesized poly(2-methyl-1-pentene sulfone) (PMPS) and poly(1-hexene sulfone) (PHS) with and without a photobase generator. We studied the photodegradation (172 nm or 254 nm) of thin films in vacuum. Spectroscopic …

Understanding and modeling nonlinear behavior is becoming more important in many modern engineering applications. One area that is relatively unexplored is how nonlinearity affects environment testing. This can cover a wide variety of subtopics, but this thesis focuses on failures that can occur in a system which are not predicted by corresponding linearized systems. To further limit the scope of this work, and to provide a context …


Procedural Pre-Training For Visual Recognition, Connor S. Anderson Jun 2024

Procedural Pre-Training For Visual Recognition, Connor S. Anderson

Theses and Dissertations

Deep learning models can perform many tasks very capably, provided they are trained correctly. Usually, this requires a large amount of data. Pre-training refers to a process of creating a strong initial model by first training it on a large-scale dataset. Such a model can then be adapted to many different tasks, while only requiring a comparatively small amount of task-specific training data. Pre-training is the standard approach in most computer vision scenarios, but it's not without drawbacks. Aside from the cost and effort involved in collecting large pre-training datasets, such data may also contain unwanted biases, violations of privacy, …

Manipulating Colloidal Particles Using Chemical Gradients And Top-Down Control, Mark Nichols Mcdonald Jun 2024

Manipulating Colloidal Particles Using Chemical Gradients And Top-Down Control, Mark Nichols Mcdonald

Theses and Dissertations

Colloidal particles provide the ideal building blocks for the next generation of microdevices, such as advanced sensors and precision drug delivery systems. However, many such applications require the use of top-down (i.e. humanly controllable) forces to manipulate colloidal particles with single-particle precision, and current methods can only achieve such precision for small numbers of particles at a time. To address this challenge, we propose using chemical forces in combination with existing top-down techniques to enable the control of larger numbers of particles simultaneously. Controlling colloids using chemical reactions is a novel technique not typically utilized. Due to its distinct difference …


Leveraging Biological Mechanisms In Machine Learning, Kyle J. Rogers Jun 2024

Leveraging Biological Mechanisms In Machine Learning, Kyle J. Rogers

Theses and Dissertations

This thesis integrates biologically-inspired mechanisms into machine learning to develop novel tuning algorithms, gradient abstractions for depth-wise parallelism, and an original bias neuron design. We introduce neuromodulatory tuning, which uses neurotransmitter-inspired bias adjustments to enhance transfer learning in spiking and non-spiking neural networks, significantly reducing parameter usage while maintaining performance. Additionally, we propose a novel approach that decouples the backward pass of backpropagation using layer abstractions, inspired by feedback loops in biological systems, enabling depth-wise training parallelization. We further extend neuromodulatory tuning by designing spiking bias neurons that mimic dopamine neuron mechanisms, leading to the development of volumetric tuning. This …

What The Eye Doesn't See: The Power Of Non-Ocularcentric Engagement In Museum Learning, Sophie J. Houghton Jun 2024

What The Eye Doesn't See: The Power Of Non-Ocularcentric Engagement In Museum Learning, Sophie J. Houghton

Undergraduate Honors Theses

Museums are unique spaces of teaching and learning. Museum exhibits transcend the constraints of classroom learning by leveraging visitors’ curiosity and allowing for increased learning autonomy. However, this learning often comes solely through visual interaction, due to museums’ role in preservation and protection of their collection. Though visual-based learning is common in museums and in Western education at large, multisensory elements cement learning autonomy and prompt visitors to learn through play. These principles are exemplified through children’s’ museums, science museums, and museum adaptations for blind and low-vision visitors. Through multisensory adaptations, traditional museums can transform their impact on visitors. This …

The Institutionalization Of Jazz Pedagogy As Observed In The Greater Salt Lake Area Of Utah, Jens Watts Jun 2024

The Institutionalization Of Jazz Pedagogy As Observed In The Greater Salt Lake Area Of Utah, Jens Watts

Undergraduate Honors Theses

Although traditionally an oral art form, the learning and teaching of jazz music has undergone a shift towards institutionalization and formalization in the last fifty years, principally in the form of method books and the presence of jazz in educational institutions. This study documents this trend by a comparison of jazz pedagogy experienced by and used by professional musicians in Utah with that which is recorded in Paul Berliner’s Thinking in Jazz. The informality of education for Berliner’s interlocutors contrasts starkly with the institutionalized education of most of the participants in this study.
