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 …

Reservoir Characterization And Basin Modeling Of Mesozoic Siliciclastic Strata For Sedimentary Geothermal Exploration, Iron County, Utah, Theodore L. Morgan

Theses and Dissertations

The transition zone between the Colorado Plateau and Basin and Range provinces of southwestern Utah provides excellent opportunities for future geothermal resource development. A combination of large fault-controlled extensional basins with outcrop analogs along basin margins, an elevated heat flow and thermal regime and the presence of porous and permeable sedimentary formations within extensional sedimentary basins allow for sedimentary geothermal exploration and development. Utilizing a reservoir-centered approach has the potential to dramatically expand the economic limits of geothermal plays in both established and frontier basins. This study characterizes a sedimentary geothermal system in Iron County Utah, centered on the Escalante …

The Psychological Effects Of Ice Conditions In Long-Term Space Travel, Jamen W. Barker Apr 2025

The Psychological Effects Of Ice Conditions In Long-Term Space Travel, Jamen W. Barker

Student Works

The psychological effects of long durations spent in space remain largely unexplored, as do potential treatments for these effects. This review compiled data from 19 articles found via searches on the APAPsychInfo and Google Scholar databases, as well as a few ancillary sources. These studies are relevant to the study of the psychological effects of space travel and isolated, confined, or extreme (ICE) environments, and research into means of addressing them, as well as limitations in current literature on the topic. Studies found sleep deprivation, largely due to microgravity, to be a contributing factor to increased stress in space. Social …

Analysis Of Nitrogen Accumulation And Gene Expression In Hydroponically-Grown Chenopodium Genotypes, Teal Kalt Apr 2025

Analysis Of Nitrogen Accumulation And Gene Expression In Hydroponically-Grown Chenopodium Genotypes, Teal Kalt

Theses and Dissertations

Nitrogen (N) is an essential macronutrient required by all plants to complete their life cycles. Inefficient N uptake contributes to over fertilization and subsequent environmental and sustainability issues resulting in the need for improved nitrogen use efficiency (NUE). Chenopodium quinoa is a resilient pseudocereal crop that is relatively adapted to N-deficient soils. Previous studies have uncovered the unique genetic structure of quinoa and its physiological responses to N availability; however, gaps remain in understanding its molecular mechanisms for NUE. This study investigates four quinoa genotypes (Real-1, 0654, KU-2, and QQ74) hydroponically grown in N-deficient conditions. RNA sequencing (RNA-seq) analysis identified …

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 …

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 …

An Exploration Of The Relationship Between Divorce And Children Of Divorce’S Romantic Relationships In Adulthood, Carlie Mccleary Apr 2025

An Exploration Of The Relationship Between Divorce And Children Of Divorce’S Romantic Relationships In Adulthood, Carlie Mccleary

Student Works

Divorce is a common occurrence in around 50% of marital relationships, and has profound effects on children born within those unions, particularly in their adult, romantic relationships. In this literature review, I compiled 12 sources from three journals in order to explore the relationship between divorce and children’s romantic relationships in the future. Primarily, findings indicated two major outcomes for children of divorce: lack of respect for the institution of marriage and also a lower level of commitment to their romantic partners. Both of these in turn impact their current and future relationships by lowering their overall satisfaction and investment …

"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 …

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 …

Superheroes To Regular Joes The Vietnam War Through The Lens Of American Comic Books And Cartoons, Ella Henricksen Apr 2025

Superheroes To Regular Joes The Vietnam War Through The Lens Of American Comic Books And Cartoons, Ella Henricksen

The Thetean: A Student Journal for Scholarly Historical Writing

Historians generally agree that American comic books got their start in 1842 with Rodolphe Töpffer’s The Adventures of Mr. Obadiah Oldbuck,1 but pairing images with text is far from a novel idea—it is practically as old as the invention of writing. By the late 1800s, cartoons and caricatures were staples in papers. Satirical editorial cartoons poked at serious issues, and single- panel gag cartoons showed a humorous picture with a caption. Short comic strips like The Yellow Kid featured regularly appearing characters,2 and in 1933, Famous Funnies (a reprinting of popular humorous news comic strips) finally made the jump to …

Pain For Profit The Motivations Of Slave Surgeons In The Eighteenth To Nineteenth Century Caribbean, Gabe Smock Apr 2025

Pain For Profit The Motivations Of Slave Surgeons In The Eighteenth To Nineteenth Century Caribbean, Gabe Smock

The Thetean: A Student Journal for Scholarly Historical Writing

When late eighteenth- century British surgeon Dr. Alexander Falconbridge ventured belowdecks to check on the hundreds of slaves chained there, he had no illusions about the horrors of the Middle Passage. After all, this was not his first voyage providing medical care for slaves until they disembarked at the infamous markets of colonial Kingston, Jamaica. He took a moment to brace himself, then ventured down into the damp air below only to encounter a sight so awful that it was difficult to put into words when he recounted the experience years later to Parliament. As a consequence of being packed …

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 …

Blood In The Snow The Mormon-Timpanogos Conflict At Battle Creek, Nathan Hale

The Thetean: A Student Journal for Scholarly Historical Writing

On March 5th, 1849, a group of 36 Mormon men surrounded the Native American camp of a small band of Timpanogos at Battle Creek, which is present-day Pleasant Grove, Utah. The Mormon militia suspected this band of cattle rustling, and a conflict ensued that resulted in the shooting and killing of four Timpanogos men. During the battle, the women and children of the native camp took cover and endured exposure to the cold elements and frigid water of Battle Creek. Six days later, these same women and children arrived in Salt Lake City. Among the group of Native American survivors …

Remembering The Lady Representations Of Abigail Adams In The Women’S Rights Movement, Allison Haack Apr 2025

Remembering The Lady Representations Of Abigail Adams In The Women’S Rights Movement, Allison Haack

The Thetean: A Student Journal for Scholarly Historical Writing

In November 1975, Redbook, a women’s magazine, included a “call to action” issued to women of the United States. This call was set forth both in response to the bicentennial celebration of the Declaration of Independence as well the UN National Women’s Year. In it, over fifty organizations came together to lay out an eleven-step plan to achieve greater political equality between the sexes—namely, the ratification of the Equal Rights Amendment. To introduce this call to action, Bess Myers, the author, shared several anecdotes about Abigail Adams, including Adams’ charge that her husband “remember the ladies” when he went off …

“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

The Incomplete Conquest Of Spanish Guinea 1471-1910, Pual Guajardo Apr 2025

The Incomplete Conquest Of Spanish Guinea 1471-1910, Pual Guajardo

The Thetean: A Student Journal for Scholarly Historical Writing

Mary Henrietta Kingsley, the famous early female explorer of Africa, once remarked that an appointment to the Equatoguinean island of Fernando Po was “equivalent to execution, only more uncomfortable.”1 Similarly, historian Randall Fegley remarked that Port Clarence, which became the capital of Equatorial Guinea, was known as “death’s waiting room.”2 When we think of the Spanish Empire, we usually envision the empire that decimated the Aztecs and the Incas, not a regime that failed to conquer and colonize an island one-fifth the size of Hawaii. Yet, for more than 400 years, the small indigenous community of Fernando Po quietly defied …

The Disrupted Symphony Of Speech: A Lesion Network Mapping Analysis Of Apraxia Of Speech, Payton Harris, Harrison Moore, Milija Grotenhuis, Jared Nielsen, Michael A. Ferguson

FHSS Mentored Research Conference

Apraxia of Speech (AOS) is a motor speech disorder that causes difficulty planning and coordinating the movements necessary for speech. This study uses lesion network mapping to identify the neural connections of AOS by tracing lesion data and analyzing their functional connectivity patterns. Our data indicates strong connectivity between the left primary motor cortex and right premotor cortex. The findings of the left primary motor cortex differ from most AOS research but still correlate with regional functions found in healthy populations. However, results related to the right motor cortex were much less expected, and suggested a larger, understudied role in …

Social Gaps & Urban Divides: How Social Factors Shape Economic Disadvantage In American Cities, Parker J. Peterson, Ruth Kerry

FHSS Mentored Research Conference

This research examines the relationship between nonmarriage, education, and socioeconomic disadvantage across census tracts in Boston, Los Angeles, and Salt Lake City. Statistical analyses reveal significant differences in never-married proportions between cities, with strong correlations between nonmarriage and community disadvantage. Even when controlling for other factors, nonmarriage remains a significant predictor of disadvantage, though spatial regression shows education is the strongest predictor in Boston.
