Improving Devices To Measure The Thermal Conductivity Of Molten Halide Salts, Ryan J. Ruth Apr 2025

Improving Devices To Measure The Thermal Conductivity Of Molten Halide Salts, Ryan J. Ruth

Theses and Dissertations

Molten salts are of high interest for use in nuclear reactors, though their thermophysical properties are notoriously hard to measure due to the extreme conditions created by them. Significant gaps remain in thermal conductivity and heat capacity data, which this work seeks to fill by improving the Needle Probe-a modified transient hot wire probe originally used by Merritt et al to measure the thermal conductivity of FLiNaK- measuring two new salts, and exploring new materials for use with molten salts. Improvements made to the Needle Probe include automation to reduce human error, more accurate heat generation modeling, a more thorough …

Strength And Ductility Of Rod-Braced Diaphragms In Metal Building Systems Subjected To Earthquake Ground Motions, James Niedens

Theses and Dissertations

Metal building systems are a common form of construction but the behavior of roof diaphragms in metal buildings that are subjected to earthquake ground motions is not entirely understood. In this study, the strength and ductility of rod-braced diaphragms with hillside washer connections or rod-pad connections was determined using experimental tests and computer simulation. Tensile tests of rods were used to determine the effect of the type of rod on strength and ductility. Two types of rods were tested, full-body rods with cut threads at each end of the rod and bracing rods with rolled threads. Three rod sizes (5/8 …


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 …

This study characterizes a sedimentary geothermal system in Iron County Utah, centered on the Escalante …


Aesthetics In Instructional Design, Dennis M. West Apr 2025

Aesthetics In Instructional Design, Dennis M. West

Theses and Dissertations

This multi-article dissertation examines how aesthetics enhances instructional design to foster engaging, transformative learning experiences. Despite its potential, aesthetics is often granted a secondary status in design practice, being seen as less important than functionality. The first article explores philosopher Monroe Beardsley's five aesthetic criteria--object-directedness, felt freedom, detached affect, active discovery, and wholeness--through a theoretical literature review, proposing their application to elevate learner engagement and interest. The second article, a qualitative investigation, analyzed the Cybermatics Playable Case Study (PCS; a cybersecurity simulation) from the perspective of Beardsley's aesthetic criteria. This investigation involved four students and two designers interviewed hermeneutically over …


Analysis Of Radial Inlet Distortion On Transonic Fan Performance, Tyler M. Reedy Apr 2025

Analysis Of Radial Inlet Distortion On Transonic Fan Performance, Tyler M. Reedy

Theses and Dissertations

Improving fan design and performance prediction requires an understanding of the impacts of inlet distortions. Inlet distortion describes any non-uniform distribution in the flow, usually referring to deviations in pressure and temperature. Using full annulus Unsteady Reynolds-Averaged Navier Stokes (URANS) simulations, the effects of both hub and tip radial distortions on the Air Force Research Lab (AFRL) Rotor 4 fan are analyzed. Overall performance, total pressure (Pt) distortion transfer, and total temperature (Tt) distortion generation are presented and compared for three operating points: near-stall, design, and choke. Hub radial inlet distortion magnitudes of 15% and 20%, and a tip radial …

"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 …

An Analysis Of The Encryption Algorithms Proposed For The Mqtt Protocol On Resource Constrained Iot Devices, John Joseph Keenan Apr 2025

An Analysis Of The Encryption Algorithms Proposed For The Mqtt Protocol On Resource Constrained Iot Devices, John Joseph Keenan

Theses and Dissertations

As more IoT devices are used to gather data and automate devices throughout the world, more security solutions are needed to keep these devices and the data they transmit secure. Many of these devices use the MQTT protocol, which does not encrypt the transferred data by default. The TLS/SSL protocols are the standard proposed solution for encrypting this traffic, but many resource constrained IoT devices do not have enough resources to run these protocols efficiently. Because of this, many other encryption algorithms have been proposed or designed for resource constrained IoT devices running the MQTT protocol, but very limited research …

Lyle H. Moon, mayor of Sugar City, Idaho, was a petroleum man. He drove trucks for the greater area of Southeastern Idaho, supplying all their petroleum needs. On June 5, 1976, his route took him within a mile and a half of the Teton Dam. Unbeknownst to him, the dam had sprung several leaks that morning. Two bulldozer crews labored through the morning, trying desperately to plug the holes. While on his route, radio operators called him and told him to drive away from the dam as quickly as possible. Thinking it was a joke, Moon quipped, “Tell me another …


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 …

“To Inherit God Himself?” The Metaphysical Transformation Of Man As Theorized In Cotton Mather’S Biblia Americana, Michael Green Apr 2025

“To Inherit God Himself?” The Metaphysical Transformation Of Man As Theorized In Cotton Mather’S Biblia Americana, Michael Green

The Thetean: A Student Journal for Scholarly Historical Writing

The tumult of the Enlightenment was enormous, not least in its impact on theologians of the late seventeenth and early eighteenth centuries. Biblical exegesis (explanation of a scriptural text based on its own historical and cultural circumstances) of the Reformation that idealized interpretations grounded in unerring prophetic figures were suddenly and forcefully subjected to the tide of historical literalism propagated by major intellectual figures such as Hugo Grotius and Baruch Spinoza. They and their cohort believed that the Bible should be treated as a historical source and its merits scrutinized based on its literal accuracy

Reconstruction From Variable Aperture Measurements Using Band-Limited Inversion Algorithms, Harrison C. Garrett Apr 2025

Reconstruction From Variable Aperture Measurements Using Band-Limited Inversion Algorithms, Harrison C. Garrett

Theses and Dissertations

The signal reconstruction process from discrete samples is inherently band-limited due to the limited amount of spectral content in the discrete set of measurements. In the case of 1D sampling using ideal measurements, the maximum bandwidth of regular and irregular sampling is well known using Nyquist and Gröchenig sampling theorems and lemmas, respectively. However, determining the appropriate reconstruction bandwidth becomes difficult when considering 2D sampling geometries, samples with variable apertures, or signal to noise ratio limitations. Instead of determining the maximum bandwidth a priori, this thesis introduces the use of a bandlimited inverse to simultaneously reconstruct a signal and determine …

Reassessing The Use Exemption: Constitutional Tensions In The Lanham Act, Caleb Nelson, Abigail Peterson Apr 2025

Reassessing The Use Exemption: Constitutional Tensions In The Lanham Act, Caleb Nelson, Abigail Peterson

Brigham Young University Prelaw Review

In today’s global economy, where new products and services are being created and marketed at an unprecedented rate, a fundamental inconsistency exists within U.S. trademark law. While domestic applicants in the United States are required to provide proof of use when applying for trademark registration, foreign applicants are statutorily exempt from providing evidence that they actually use their trademarks. This disparity, which has gone unaddressed for decades, puts small and mid-sized American businesses and individuals at a disadvantage to their foreign counterparts.


Closing The Distance Between Congress’S Intent And Fosta’S Text, Grant F. Gurr, Henry Purser Apr 2025

Closing The Distance Between Congress’S Intent And Fosta’S Text, Grant F. Gurr, Henry Purser

Brigham Young University Prelaw Review

It has now been almost thirty years since Congress enacted the Communications Decency Act (CDA), and during that time, sex trafficking has become deeply intertwined with social networking and online advertisements. Internet service providers not only facilitate and profit from online sex trafficking and related crimes like the distribution of child pornography, but, thanks to CDA Section 230, these companies are largely immune to victim-led legal challenges. In 2018, Congress passed the Fight Online Sex Trafficking Act (FOSTA) to limit this immunity and provide victims with legal recourse. However, scholarly consensus suggests that FOSTA has failed to achieve its intended …
