Gnss-Denied Navigation Using Lte Signals Of Opportunity On Low-Cost, Low-Swap Hardware, Tyler Sweat Apr 2025

Gnss-Denied Navigation Using Lte Signals Of Opportunity On Low-Cost, Low-Swap Hardware, Tyler Sweat

Theses and Dissertations

Global navigation satellite system (GNSS) navigation is crucial in the operation of unmanned aerial vehicles (UAV). GNSS signals are susceptible to jamming, spoofing, multipath, and urban canyons and may provide incorrect position information or may not be available at all. For autonomous missions, a backup for GNSS is desirable in the event that it is unavailable. Terrestrial cellular signals are a promising option for navigation because they are continuously transmitted at higher power levels. Optimizing hardware size, weight, and power (SWaP) is critical for UAVs to maximize endurance, payload capacity, and operational efficiency. We present a system that uses long-term …

Understanding Dialogic Interactions In Online Religious Education, Isaac Munoz Moreno Apr 2025

Understanding Dialogic Interactions In Online Religious Education, Isaac Munoz Moreno

Theses and Dissertations

In this study, I explored how Latter-day Saint higher education professors experienced and facilitated dialogic interactions in online religion courses. Seven instructors who taught synchronous and asynchronous virtual courses at Brigham Young University participated in semi-structured interviews focused on their pedagogical approaches, relational practices, and perceptions of student engagement. Guided by hermeneutic phenomenology and drawing on principles of dialogic pedagogy, I explored how religion instructors cultivated dialogue in virtual classrooms grounded in doctrinal instruction. The findings revealed how professors created a relational presence, navigated institutional constraints, and fostered deep learning and spiritual growth environments. While some participants viewed online dialogue …

A Novel Wrench Decomposition And Development Of A Large-Scale Soft Robot For Displacement-Based Human-Robot Collaborative Manipulation, Dallin Cordon Apr 2025

A Novel Wrench Decomposition And Development Of A Large-Scale Soft Robot For Displacement-Based Human-Robot Collaborative Manipulation, Dallin Cordon

Theses and Dissertations

This work represents an examination of various facets of physical human-robot collaborative manipulation and the implementation of compliant, soft-robotic manipulators. A survey of physical human-human interaction and haptic communication is presented, alongside an investigation into the decomposition of force and torque components that enable effective human-robot collaboration. To address the inconsistent terminology found in previous literature, a standardized framework for force decomposition is proposed. A new taxonomy is introduced to categorize the force components involved in collaborative manipulation tasks. This taxonomy clarifies the role of each component in an agent's applied force during task execution and provides a structured framework …

Testing And Modeling Of Nonlinearities In Riveted And Bolted Structures, Joshua E. Blackham Apr 2025

Testing And Modeling Of Nonlinearities In Riveted And Bolted Structures, Joshua E. Blackham

Theses and Dissertations

Joints are difficult to model because of various small-scale and nonlinear features, such as local geometry, preload, friction and contact. These features cause a local change in stiffness and energy dissipation which result in changes in the effective natural frequency and damping of the whole structure. Past studies have found good success using nonlinear Iwan elements as whole joint models for bolted joints in a few different structures. In Chapter 3, a similar approach is proposed for modeling riveted joints, which seeks to capture the vibrational response of a test structure including changes in the effective modal frequency and damping …

Wind Collapse Risk And Serviceability Drift Of Steel Concentrically Braced Frame Buildings, Sarah Corrinne Partington Cluff Apr 2025

Wind Collapse Risk And Serviceability Drift Of Steel Concentrically Braced Frame Buildings, Sarah Corrinne Partington Cluff

Theses and Dissertations

Seismic design provisions use the ductility and reserve strength of the lateral structural system to reduce the loads used in design, making the structural design more economical while maintaining life safety. In contrast, current wind design provisions do not. Conventional wind design relies primarily on elastic behavior. The objective of this study is to determine a wind response modification factor for steel concentrically braced frames that could be applied to reduce wind design loads based on ductility and reserve strength, while still meeting drift requirements for serviceability of the structure. To achieve the objective, three types of ductile braced frames …

"Our Darker Purpose": Jean-François Ducis's Le Roi Léar In Eighteenth-Century France, Zerin Biehn Apr 2025

"Our Darker Purpose": Jean-François Ducis's Le Roi Léar In Eighteenth-Century France, Zerin Biehn

Theses and Dissertations

Jean-François Ducis's French adaptation of Shakespeare's King Lear has received little critical attention since its publication in 1784. The play retains many of the main plot points that are familiar from Shakespeare along with Ducis's changes that helped make Shakespeare and King Lear more acceptable for the French stage. John Golder has interpreted Le Roi Léar as a pro-royalist play, but I argue that the play's portrayal of kingship and treason is much more nuanced. Ducis's Cordelia is framed for rebellion by her oldest sister, a situation which lacks the rich ambiguity of Shakespeare's Cordelia refusing to placate her father …

Steps Towards Effective Human-Robot Co-Manipulation Through Real-Time Modus Detection And Effects Of Stiffness Variation For Human-Soft-Robot Dyads, Shaden Moss Apr 2025

Steps Towards Effective Human-Robot Co-Manipulation Through Real-Time Modus Detection And Effects Of Stiffness Variation For Human-Soft-Robot Dyads, Shaden Moss

Theses and Dissertations

A group of individuals can coordinate very easily to carry a large or heavy object together. This act of collaborative carrying is called co-manipulation. Unlike human teammates, robots cannot easily detect and respond to the intent of human partners during co-manipulation tasks. This shortcoming can be compensated for via the physical design and the software design of robots. This work treats software design with a neural net that detects human modus (or the manner in which a team moves an object together) in real time. This work treats physical design with the use of a soft robot in human-robot co-manipulation, …

Integrating Temperature-Dependent Tissue Properties Into Hifu Computational Models For Enhanced Treatment Planning, Christian Kevin Valencia Narva Apr 2025

Integrating Temperature-Dependent Tissue Properties Into Hifu Computational Models For Enhanced Treatment Planning, Christian Kevin Valencia Narva

Theses and Dissertations

Objective: High-intensity focused ultrasound (HIFU) is a non-invasive therapy that ablates diseased tissues with high precision. Computational simulations using the Pennes Bioheat Transfer Equation (PBTE) can guide HIFU treatment by predicting temperature distributions and thermal dose volumes. Traditional simulations assume constant thermal and acoustic properties, which may oversimplify tissue behavior. Methods: This study evaluates the impact of integrating temperature-dependent thermal properties (thermal conductivity, specific heat capacity, and perfusion) in finite-difference time-domain HIFU simulations. Three scenarios were simulated: (1) a homogeneous liver with both high- and low-power sonications, (2) a rabbit thigh muscle validated against preclinical MRTI data, and (3) an …

Development And Evaluation Of Canbench: A Testbed For Assessing The Security Of Automotive Can Buses, Trevor S. Mcclellan Apr 2025

Development And Evaluation Of Canbench: A Testbed For Assessing The Security Of Automotive Can Buses, Trevor S. Mcclellan

Theses and Dissertations

Modern vehicles rely heavily on electronic control units (ECUs) that communicate via the controller area network (CAN) bus, a protocol developed in the 1980s with minimal security considerations. The growing number of ECUs has heightened the risk of cyberattacks on vehicles. Although CAN bus security has been extensively researched, the CAN standard still lacks built-in security measures. Furthermore, testing proposed security mechanisms is challenging due to the proprietary nature of automotive systems. To address this, an open-source physical testbed was developed using inexpensive, off-the-shelf components to support automotive CAN bus security research. The testbed provides a controlled environment for simulating …

Using Human Computation And Harmonic Expansions For Characterization And Design Of Grain Boundary Networks, Christopher W. Adair Apr 2025

Using Human Computation And Harmonic Expansions For Characterization And Design Of Grain Boundary Networks, Christopher W. Adair

Theses and Dissertations

Grain Boundary Networks (GBNs) are a high-dimensional feature in polycrystalline microstructural materials that are formed from the crystallographic degrees of freedom. This feature affects multiple material properties such as diffusivity, fracture, elasticity, heat transfer, and others. The link between the crystallography and the material properties is called the structure-property linkage, and allows for simulation and design of materials. While it is possible to use the structure-property linkage to design materials for better performance, the high-dimensional nature of the interconnected grain boundaries preclude the use of many common optimization algorithms for efficiency or local minima considerations. This work shows how the …

"Because He Was A Cripple": Collective Care And The Theory Of Complex Embodiment In Dickens's A Christmas Carol, Briley Wyckoff Apr 2025

"Because He Was A Cripple": Collective Care And The Theory Of Complex Embodiment In Dickens's A Christmas Carol, Briley Wyckoff

Theses and Dissertations

Published in 1843, Charles Dickens's A Christmas Carol planted itself squarely into a society that depended upon physical labor and valued able-bodiedness. The crutch-bearing Tiny Tim is iconized for his angelic nature and positive outlook on his impairment, prompting critical conversation about narrative prosthesis and poster children, yet the other illustrations of disability in the novella are rarely explored. Contrary to the tendency of disability scholars to conclude that A Christmas Carol leans too heavily into the trope of inspirational disability or diminishes disabled agency, Dickens's incorporation of disability actually extends far beyond Tim as each member of the Cratchit …

The Development Of Electroanalytical Methods For Molten Salt Mixtures Under Static And Flowing Conditions, Ranon Fuller Apr 2025

The Development Of Electroanalytical Methods For Molten Salt Mixtures Under Static And Flowing Conditions, Ranon Fuller

Theses and Dissertations

Electroanalytical methods have the potential to characterize molten salt systems in situ, determine physical properties such as diffusion coefficients and standard potentials, and measure kinetic and corrosion rates. Due to experimental difficulties of working with molten salts including high temperatures and high natural convection, transport, kinetic, and corrosion rates, many precise, consistent methods have yet to be established. In this work, we describe methods to precisely calculate standard reduction potentials, characterize molten salt solutions containing multiple lanthanides by reduction potentials and metal deposition mechanisms, calculate the number of electrons exchanged in metal deposition using SWV, calculate diffusion coefficients using CV, …

The Possession Of John Toldervy Early Quakerism And The Polarization Of Print Polemic In Cromwellian England, Hyrum Veach Apr 2025

The Possession Of John Toldervy Early Quakerism And The Polarization Of Print Polemic In Cromwellian England, Hyrum Veach

The Thetean: A Student Journal for Scholarly Historical Writing

In the winter of 1655, ex- demoniac, dismissed apprentice, and sometime Quaker John Toldervy published a short memoir entitled The Foot out of the Snare.1 The pamphlet presented itself as a part conversion narrative and part anti- Quaker exposé, and told a startling story of demonic possession. After Toldervy became a Quaker, he told his readers, his mind was corrupted by a “seducing spirit” that convinced him that he was both Christ and the Archangel Michael and drove him to perform many bizarre acts.2 Two months later, after a brief pamphlet war with soon- to- be- disgraced Quaker James Nayler,3 …

Japanese Imperial Education In Korea And Taiwan And The Lens Of Reciprocal Assimilation, Devin Sanders

The Thetean: A Student Journal for Scholarly Historical Writing

During the 19th century, the nation of Japan underwent a variety of political, social, and economic changes, including but not limited to events such as the Meiji Restoration in 1868 and the first Sino-Japanese War in 1894-1895. This paradigmatic shift sought to usher in a new era of Japanese dominance on both regional and international scales. Japanese dominance and international relevance, as indicated by Meiji-era domestic and foreign policy, was to be realized through adopting demonstratively successful policies, technologies, ideals, governments, militaries, economic approaches, and even the appearances of Western powers.1 Indeed, influential Japanese leaders such as Fukuzawa Yukichi believed …

An Investigation On Food Restriction In The Medieval British Church, Cope Makechnie-Hardy Apr 2025

An Investigation On Food Restriction In The Medieval British Church, Cope Makechnie-Hardy

The Thetean: A Student Journal for Scholarly Historical Writing

When Seaxburh, Queen of the Anglo-Saxon kingdom of Kent, retired to her sister’s newly established religious house at Ely in 665 she was a physically broken woman, with “wan cheeks from fasting” and a body frail from years of food restriction.1 Already throughout her life Seaxburh had used her body as an integral part of her devotion to Christ, and after arriving at Ely “signed her stomach with the mark of Christ so that she might not burden it with food.”2 Nearly six hundred years later, Saint Elizabeth of Hungary would engage in a similar practice, referred to by historians …
