Model Predictive Control Of A Lab-Scale Thermal Energy Storage System In Relap5-3d, Jaron Wallace, Daniel Hill, David Thurston, John Hedengren, Matthew Memmott Jan 2024

Model Predictive Control Of A Lab-Scale Thermal Energy Storage System In Relap5-3d, Jaron Wallace, Daniel Hill, David Thurston, John Hedengren, Matthew Memmott

Faculty Publications

Increased renewable energy penetration of an electrical grid generally creates more supply fluctuations. Traditional base-load systems, such as nuclear power, can be retrofitted with thermal energy storage (TES) systems to meet supply demand fluctuations. These systems can store energy during low electricity demand times to allow the reactor to operate at constant power while simultaneously fluctuating electricity output. The control of these systems is of vital importance and Model Predictive Control (MPC) is a leading control mechanism for optimized production plans with forecast information. This study combines high fidelity RELAP5-3D models with MPC to control an experimental benchtop system that …


Comparison Of Empirical And Analytical Eigenfunctions As Bases For Reduced Order Methods In Heat Transfer, Jakob G. Bates, Matthew R. Jones, Christopher R. Dillon, John Tencer Jan 2024

Comparison Of Empirical And Analytical Eigenfunctions As Bases For Reduced Order Methods In Heat Transfer, Jakob G. Bates, Matthew R. Jones, Christopher R. Dillon, John Tencer

Student Works

Reduced order methods using spectral representations show promise in facilitating and accelerating heat transfer analyses. This paper proposes a taxonomy for reduced order methods, classifying a method as reduced order compression, modelling, or analysis. The performance of bases formed with analytical and empirical eigenfunctions are compared for representative reduced order tasks. The Akaike Information Criterion is applied in a novel way to compare the performance of these bases. The present study finds that both bases are parsimonious for reduced order compression tasks. Empirical eigenfunctions are more robust to for reduced order modelling with variations in modelling parameters such as thermal …

The Effects Of Medical Misinformation On The American Public, Jessica Ashby Jan 2024

The Effects Of Medical Misinformation On The American Public, Jessica Ashby

Ballard Brief

Medical misinformation has always existed, but it has recently become more frequent due to the development of the internet and social media. Medical misinformation can cover a wide variety of topics, and studies show that some groups are more likely to be affected by medical misinformation than others, like those with less trust in health care, less health literacy, and a more positive attitude toward alternative medicines. Aspects of the internet, like echo chambers and algorithms, have contributed to the rise of medical misinformation, along with belief in anecdotal evidence and alternative remedies that are not backed by science. Some …


Lack Of Access To Quality Education For Rural Indigenous Communities In Chiapas, Mexico, Elizabeth Sanchez Jan 2024

Lack Of Access To Quality Education For Rural Indigenous Communities In Chiapas, Mexico, Elizabeth Sanchez

Ballard Brief

The Mexican state of Chiapas has the highest indigenous population in the country and the least educated population of any state. The confluence of historical government neglect (in infrastructure and politics), gender inequality, language barriers, and low family income of these populations seriously hinders indigenous Chiapanecos from receiving a high-quality education—if any education at all. A history of indigenous marginalization and government unwillingness to recognize and remedy this creates a serious roadblock to any permanent change in indigenous education levels. These low levels of education lead to an increase in reproductive health illiteracy, lower occupational attainment and advancement, and decreased …


An Analysis Of The Financial Incentives In Attacking The Restoration, Ron C. Rhodes Jan 2024

An Analysis Of The Financial Incentives In Attacking The Restoration, Ron C. Rhodes

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

With the popularity of social media growing exponentially, prominent critics of the Church are leveraging the platforms, particularly YouTube, as a key resource to produce thousands of negative videos about the Church. The accusations made in the videos about Church history, leadership, doctrine, and culture are so numerous that it could take months or even years to research fully, all while the flood of new content continues. It is easy for those exposed to the accusations to be overwhelmed by the sheer volume and, therefore, assume at least some of it must be true. This could place at least some …


The Harmful Effects Of Living In Brick Kiln Communities In The South Asia Region, Cambrie Ball Jan 2024

The Harmful Effects Of Living In Brick Kiln Communities In The South Asia Region, Cambrie Ball

Ballard Brief

Across South Asia, brick kilns pose significant health challenges, socioeconomic disparities, and environmental degradation due to hazardous air quality and exploitative labor practices. The poor infrastructure of kiln sites contributes to dangerous working and living conditions for laborers and their families, which remain unregulated due to the sector’s informal nature. These kilns emit substantial amounts of pollutants, including particulate matter and carbon dioxide, leading to respiratory and cardiovascular diseases and premature deaths. Furthermore, indoor air pollution from burning solid fuels exacerbates health risks, particularly for women and children. Poverty and low wages persist among kiln workers, with many trapped in …


A Backpack In The River, Shamae Budd Jan 2024

A Backpack In The River, Shamae Budd

Inscape

That morning, we awoke to the silence of snow—the first snowfall that winter, like white gauze, an inch thick on the cars and lawn and pavement, exhilaratingly blank after the red and yellow color-chaos of autumn. I looked out the window and pulled my winter boots from the closet, tugging my husband to join me for a walk before breakfast. Two months married, we bundled ourselves into knitted hats and scarves and gloves and made our way to the river trail, listening to the muffled sound of our feet leaving prints in the snow.

The Widow Interim, Kath Richards

Inscape

A metronome outside his skin, like he wears on his person the grandfather clock from his grandfather’s home. Between his lungs, the dacron droning of muscle pumping the piece of poly-carbon which will play valve so long as his heart will have it.


Insights Into The Story Of Korihor Based On Intertextual Comparisons, Noel Hudson Jan 2024

Insights Into The Story Of Korihor Based On Intertextual Comparisons, Noel Hudson

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

A brief outline of the saga of Korihor, the Anti-Christ, is provided along with a discussion of his affinities with other Book of Mormon anti-Christs, including those in the order of Nehors. Literary allusions suggesting Korihor as a foil to the king of the Lamanites are examined. Evidence of a schism among the order of Nehors leading to violence is discussed. Korihor’s unusual death is examined within the context of the theme of crushing the serpent from the stories of Adam, Eve, and Cain.


More Evidence For Alma As A Semitic Name, Neal Rappleye, Allen Hansen Jan 2024

More Evidence For Alma As A Semitic Name, Neal Rappleye, Allen Hansen

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

Beginning with Hugh Nibley, several Latter-day Saint scholars have highlighted a deed found among the Bar Kokhba documents as evidence of the name Alma as a Jewish male name in antiquity. Here we highlight a second attestation of the same name used for a Jewish male from a slightly earlier period, as well as other evidence from Hebrew toponymy that helps corroborate not only that Alma is a Hebrew name, but also supports the etymology proposed by Latter-day Saint scholars and is suggestive of wordplays previously identified in the Book of Mormon text. Past critics have mocked the name Alma …


A Sociolinguistic View Of Cultural Influences In Conversations About Religion, Rachael Merrill Jan 2024

A Sociolinguistic View Of Cultural Influences In Conversations About Religion, Rachael Merrill

BYU Asian Studies Student Journal

My research project deals with intercultural communication issues in religious conversations among American English speakers and Japanese speakers. Much research has been done to examine how miscommunications occur across cultures, and that understanding cultural contexts can help us be more successful in linguistic endeavors. This paper specifically examines how the different sociocultural meanings attached to individual lexical items associated with religious topics (e.g., ‘God’ and ‘prayer’) differ between English and Japanese. This is a qualitative study using data from publicly available corpora of Japanese and English, as well as sociolinguistic interviews. I will not present the analysis of the interviews …


Preserving History: The Progression Of Recordkeeping In The Church, Wayne Crosby, W. Tyson Thorpe Jan 2024

Preserving History: The Progression Of Recordkeeping In The Church, Wayne Crosby, W. Tyson Thorpe

BYU Studies

Members of The Church of Jesus Christ of Latter-day Saints have a variety of experiences with living the gospel and coming closer to Jesus Christ. Where people live, what age they are, and what their family situations are can all impact how they see God’s hand in their lives, as can a multitude of other factors. For this reason, it is important for historians examining the lived experiences of Latter-day Saints to have a variety of records to draw on in their analyses and explorations. Thankfully, the keeping of histories in Church units has been an important part of the …


All One People, Susan Elizabeth Howe Jan 2024

All One People, Susan Elizabeth Howe

BYU Studies

In his BYU Studies article “Building an Innovative ‘Latter-day Saints without Borders’ Organization,” Warner Woodworth recounts both his own and his students’ extensive work to better the lives of the poor, but he gives credit to many other Latter-day Saint groups who are carrying out similar efforts. All One People, an organization located in Manti, Utah, is one of these groups. Woodworth says that these groups “[act] as ‘social entrepreneurial’ Christians who draw on their faith, rely on scriptural values, harness their educations, and call forth their business skills in designing and launching effective humanitarian services.” These are exactly the …


Department And Individual Efforts To Amplify Prophetic Messages, Scott C. Esplin, Brad Streeter, Rory Bigelow, Aaron Shumway, David Peck Jan 2024

Department And Individual Efforts To Amplify Prophetic Messages, Scott C. Esplin, Brad Streeter, Rory Bigelow, Aaron Shumway, David Peck

Religious Educator: Perspectives on the Restored Gospel

This panel focuses on Church Educational System efforts to follow Elder Clark G. Gilbert’s counsel to amplify prophetic messages. An amplifier takes an input source such as a microphone and increases its amplitude or size and sends it through an output source such as a speaker. Instructors can help students reduce background noise, or contradictory information from sources other than the Savior or prophets.

Faculty Publications

As spinal fusion surgery continues to transition to less invasive techniques, there remains an unmet need for ever smaller and more complex interbody cages to meet the unique needs of this difficult surgery. This work focuses on the hypothesis that this need can be met using the inherent advantages of compliant mechanisms in a way no previous device has. Deployable Euler Spiral Connectors optimized using a gradient based optimization algorithm were used as the foundation for a device that can stow to a very small size for device insertion then bilaterally deploy to a substantially larger device footprint. Additionally, a …

This research seeks to understand parental support for online students. Using a survey, this study examined perceptions from 567 parents from eight online K-12 programs in a Midwestern state regarding their support for students’ online affective, behavioral, and cognitive engagement. Guided by the Academic Communities of Engagement Framework, our analysis identified eight main challenges parents faced when supporting their online student: (a) focus; (b) keeping on pace; (c) lack of motivation; (d) lack of organization, learning materials, live sessions, and support from online schools; (e) lack of feedback, support, and communication from teachers; (f) parents in need of additional skills …


Estimating The Likelihood Of Future Tax Settlements, Jared Jennings, Joshua A. Lee, Erin Towery Jan 2024

Estimating The Likelihood Of Future Tax Settlements, Jared Jennings, Joshua A. Lee, Erin Towery

Faculty Publications

Corporate income tax settlements represent a substantial cash outflow for many U.S. firms. This study develops an ex-ante measure of future corporate income tax settlement likelihood using quantitative and qualitative information from Form 10-K. We find that both quantitative and qualitative information are incrementally useful in predicting future tax settlements. We then use our new measure to examine the association between predicted future tax settlements and cash holdings. In contrast with prior research documenting a positive association between reserves for uncertain tax positions and cash holdings, we find that firms with a higher likelihood of future tax settlements hold less …


Chatbots Mitigate Help-Seeking Avoidance, James Gaskin, Eva Blondeel, Ryan Schuetzler, Rachel Serre, Jacob Steffen, David A. Wood Jan 2024

Chatbots Mitigate Help-Seeking Avoidance, James Gaskin, Eva Blondeel, Ryan Schuetzler, Rachel Serre, Jacob Steffen, David A. Wood

Faculty Publications

This research explores the transformative role of large language model (LLM) chatbots in fostering help-seeking behaviors among introverted and underrepresented students in educational settings. Despite the importance of help-seeking for academic success, certain groups exhibit avoidance behaviors due to self-presentation concerns and stereotype threats. By integrating LLM chatbots as non-judgmental, anonymous teaching assistants in an introductory information systems course, the study demonstrates how technology can mitigate these behaviors and promote inclusivity. The chatbots provided real-time, unbiased support, significantly enhancing the students' willingness to engage in help-seeking behaviors without fear of judgment. This practical application of chatbots not only supports academic …

Observation, Reason, Faith, And Revelation, Dale G. Renlund Jan 2024

Observation, Reason, Faith, And Revelation, Dale G. Renlund

Religious Educator: Perspectives on the Restored Gospel

While some might believe that observation and reason are at odds with faith, they in fact support our ability to receive revelation. We can be deceived when we draw conclusions based on observation, reason, or faith alone, but when used in harmony, they facilitate revelation and enable the Holy Ghost to be our constant companion. Following this pattern of revelation increases the spiritual momentum in our lives.


Decoding The Self-Tracking Symbols Of Wilford Woodruff’S Journals, Joshua M. Matson Jan 2024

Decoding The Self-Tracking Symbols Of Wilford Woodruff’S Journals, Joshua M. Matson

BYU Studies

Wilford Woodruff’s journals have been celebrated as one of the greatest textual records of the Restoration. A prominent, yet almost entirely unexplored, component of Woodruff’s journals is his creating, implementing, and consistently drawing symbols and pictures alongside his near-daily autobiographical record. Within his fifteen-volume journal spanning more than a sixty-year period, Woodruff drew approximately nine thousand images. The first of these symbols appears in an entry dated March 23, 1837, and the final image is drawn on March 19, 1897. These images can be divided into two groups. The first are unique illustrations that appear erratically throughout the journals and …

From Three-Pillars To Three-Environments: Shifting The Paradigm Of Sustainability In Civil And Construction Engineering, Xiaomei Wang, Andrew South, Clifton Farnsworth, Brett James Hashimoto

Faculty Publications

This research explores the usage of sustainability in literature and presents ‘three environments’ for addressing sustainability in the Civil and Construction Engineering (CCE) disciplines. Scholars have increasingly studied sustainability and sustainable development across CCE disciplines as the importance of sustainability awareness and action in society has increased. However, the vastness of its conceptual breadth and depth in CCE research is difficult to holistically evaluate. As a result, CCE researchers often focus on specific aspects of sustainability applied to discrete contexts, or address sustainability in broad aspirational terms and guiding motivations. This research utilized a rigorous analytical corpus linguistics approach for …
