A Pseudo-Static Model For Dynamic Analysis On Frequency Domain Of Distributed Compliant Mechanisms, Mingxiang Ling, Larry L. Howell, June Cao, Zhou Jiang

Faculty Publications

This paper presents a pseudo-static modeling methodology for dynamic analysis of distributed compliant mechanisms to provide accurate and efficient solutions. First, a dynamic stiffness matrix of the flexible beam is deduced, which has the same definition and a similar form as the traditional static compliance/stiffness matrix but is frequency-dependent. Second, the pseudo-static modeling procedure for the dynamic analysis is implemented in a statics-similar way. Then, all the kinematic, static and dynamic performances of compliant mechanisms can be analyzed based on the pseudo- static model. The superiority of the proposed method is that when it is used for the dynamic modeling …

Origami-Inspired Sacrificial Joints For Folding Compliant Mechanisms, Todd G. Nelson, Alex Avila, Larry L. Howell, Just L. Herder, Davood Farhadi Machekposhtic

Faculty Publications

Folding is a manufacturing method which can create complex 3D geometries from flat materi- als and can be particularly useful in cost-sensitive or planar-limited fabrication applications.

This paper introduces compliant mechanisms that employ folding techniques from origami to evolve from a flat material to deployed state. We present origami-inspired sacrificial joints, joints which have mobility during assembly of the mechanism but are rigid in their final position, to create regions of high and low stiffness and the proper alignment of compliant flexures in folded mechanisms. To demonstrate the method we fold steel sheet to create some well-known and complex compliant …

Normalized Coordinate Equations And Energy Method For Predicting Natural Curved-Fold Configurations, Jacob Badger, Todd G. Nelson, Rober J. Lang, Denise M. Halverson, Larry L. Howell

Faculty Publications

Of the many valid configurations that a curved fold may assume, it is of particular interest to identify natural—or lowest energy—configurations that physical models will preferentially assume. We present normalized coordinate equations—equations that relate fold surface properties

to their edge of regression—to simplify curved-fold rela- tionships. An energy method based on these normalized

coordinate equations is developed to identify natural con- figurations of general curved folds. While it has been noted

that natural configurations have nearly planar creases for curved folds, we show that non-planar behavior near the crease ends substantially reduces the energy of a fold.

Community Detection Via Persistent Homology Surfaces, Abigail Jenkins

Theses and Dissertations

Network science continues to be an area of growing interest. In this thesis we introduce new methods of analyzing the structure of networks through the use of persistent homology. We propose the notion of a network's persistent surface, which allows us to visualize a vertex's relation to the whole network from a purely homological point of view. We further introduce a method of persistent surface community detection that finds vertices that play the same structural role in the network. We describe how these concepts provide the basis for an equivalence class among the vertices of a network, and provide many …

Deep Transfer Learning For Approximate Model Predictive Control, Samuel Arce Munoz, Junho Park, Cristina M. Stewart, Adam M. Martin, John Hedengren

Faculty Publications

Transfer learning is a machine learning technique that takes a pre-trained model that has already been trained on a related task, and adapts it for use on a new, related task. This is particularly useful in the context of model predictive control (MPC), where deep transfer learning is used to improve the training of the MPC by leveraging the knowledge gained from related controllers. One way in which transfer learning is applied in the context of MPC is by using a pre-trained deep learning model of the MPC, and then fine-tuning the controller training for a new process automation task. …

We Live In The Olden Days: Reflections On The Importance Of Scientific And Theological Humility, Steven L. Clark

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

Members of The Church of Jesus Christ of Latter-day Saints have a unique perspective on truth. Our knowledge that Salvation likely involves participation in complex eternal activities requiring significantly more understanding than we currently possess naturally leads us to seek truth and, in addition, to seek an understanding of that truth. Under these circumstances, our inability to fully understand many truths, both revealed and discovered, can lead to confusion. A lack of complete understanding of accepted scientific truth generally leads the serious truth-seeker to enhanced investigative and educational efforts without doubting the ultimate veracity of the concept under investigation; we …

Theosis In The Book Of Mormon: The Work And Glory Of The Father, Mother And Son, And Holy Ghost, Val Larsen, Newell D. Wright

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

While some scholars have suggested that the doctrine of theosis — the transformation of human beings into divine beings — emerged only in Nauvoo, the essence of the doctrine was already present in the Book of Mormon, both in precept and example. The doctrine is especially well developed in 1 Nephi, Alma 19, and Helaman 5. The focus in 1 Nephi is on Lehi and Nephi’s rejection of Deuteronomist reforms that erased the divine Mother and Son, who, that book shows, are closely coupled as they, the Father, and Holy Ghost work to transform human beings into divine beings. The …

Unavailable Genetic Evidence, Multiple Simultaneous Promised Lands, And Lamanites By Location? Possible Ramifications Of The Book Of Mormon Limited Geography Theory, Brian C. Hales

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

This paper is composed of three parts connected consecutively because their conclusions build upon each other. The first part investigates the transportation methods used in the Book of Mormon, concluding that horse and river travel contributed little and that foot travel dominated all journeying. The second part uses that conclusion to estimate the overall dimensions of the Promised Land by examining Alma the Elder’s journey from Nephi to Zarahemla. This exercise reaffirms the 200-by-500-mile size promoted by John L. Sorenson decades ago. The third part looks at four ramifications of this 100,000 square-mile Promised Land footprint when stamped upon a …

“In This Batter’D Caravanserai”, Daniel C. Peterson

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

In the Rubáiyát of Omar Khayyám, based upon verses composed by an eleventh-century Persian mathematician and astronomer, the English Victorian poet Edward FitzGerald eloquently portrays human life in an indifferent, deterministic universe that lacks any evident purpose and is bereft of divine Providence. The poem’s suggested response to such a universe is an unambitious life of hedonism, distraction, and gentle despair. It is curiously modern, and those considering the adoption of anything like its worldview might want to read it, and to think about its implications, very carefully.

Aerostructural Predictions Combining Fenics And A Viscous Vortex Particle Method, Ryan Anderson, Andrew Ning, Ru Xiang, Sebastiaan P. C. Van Schie, Mark Sperry, Darshan Sarojini, David Kamensky, John T. Hwang

Faculty Publications

Electric Vertical Takeoff and Landing (eVTOL) aircraft experience complex, unsteady aerodynamic interactions between rotors, wings, and fuselage that can make design difficult. We introduce a new framework for predicting aerostructural interactions. Specifically, we demonstrate the coupling of a finite element solver with Reissner-Mindlin shell theory for computing deflections and a viscous vortex particle for capturing wakes. We perform convergence studies of the aerodynamics and the coupled aerostructural model. Finally, we share some preliminary results of the dynamic aeroelastic response of Uber’s eCRM-002 main wing, and share some qualitative observations.

Understanding The Role Of Online Teaching Assistants In Student Engagement, Sara H. Tuiloma, Charles R. Graham

Faculty Publications

In this paper, we examine how online teaching assistants (OLTAs) interact with students in terms of affective, behavioral, and cognitive support and the influence of OLTA training on these interactions. Through a thematic network analysis, using a tracking instrument and semi-structured interviews with 10 OLTAs, we examined how online university students are supported based on the quantity and quality of interactions with OLTAs, and how training contributes to interactions. Our research addressed two key questions: (1) How do OLTAs support learners in the quantity and quality of interactions? and (2) How does OLTA training around affective and behavioral support influence …

Charity As An Exegetical Principle In The Book Of Mormon, Matthew Scott Stenson

BYU Studies

The eclectic Book of Mormon effectively collapses intellectual and sacred history. Anachronisms have drawn and do currently draw the attention of some Book of Mormon students and researchers. Nicholas J. Frederick, for instance, has written extensively on the presence of New Testament language in the largely pre–Christian Era record. Not all anachronisms are so extensive and involved as those Frederick traces. Some are minor and comparatively unimportant. However, there is a significant and pervasive conceptual anachronism that deserves critical attention. I speak of the primary narrators of the Book of Mormon using faith, hope, and charity (or love) as textual …

The Stewardship Of Our First Freedom, Elder Clark G. Gilbert

BYU Studies

When Elder Quentin L. Cook of the Quorum of the Twelve Apostles of The Church of Jesus Christ of Latter-day Saints spoke at the University of Oxford’s Pembroke College about the impact of religious freedom on public morality, he charged people of faith to be effective stewards of religious freedom. Elder Cook stated, “There is no better demonstration of the great benefits associated with religious liberty than for devoted members of various faiths who feel accountable to God to model principles of integrity, morality, service, and love.” In this sense, our religious freedom stewardship extends not only to society but …

Performance Gaps And Opportunities For Growth: Addressing Remote Learning In Nevada, Anna Dreibelbis-Colquitt

BYU Education & Law Journal

Although education is not a fundamental right under the United States Constitution, it is nonetheless deemed as “perhaps the most important function of state and local governments.” The importance of education is reinforced through the Nevada Constitution. Specifically, Article 11 states that “[t]he legislature shall provide for a uniform system of common schools,” which is seen through the public school system. However, this ‘uniform’ system drastically changed two years ago with the surge in online learning.

Joseph Smith’S Education And Intellect As Described In Documentary Sources, Brian C. Hales

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

Although Joseph Smith has been credited with “approximately seven full school years” of district schooling, further research supports that his education consisted of basic instruction in “reading, writing and the ground rules of arithmetic” comprising “less than two years of formal schooling.” The actual number of terms he experienced in common schools in upstate New York is probably less critical since the curricula in district schools did not then teach creative writing, composition, or extemporaneous speaking. If Joseph Smith learned how to compose and dictate a book, extracurricular activities would likely have been the training source. Six of those can …

Institutional Support For Academic Engagement In Online And Blended Learning Environments: Exploring Affective, Behavioral, And Cognitive Dimensions, Charles R. Graham, Jered Borup, Sara Tuiloma, Adriana Martínez Arias, Ross Larsen

Faculty Publications

In light of the disruptions caused by the COVID-19 pandemic, leaders of higher education institutions around the world have been contemplating ways to help their universities engage in a digital transformation that must have student engagement and learning as the foremost considerations. This study reports on the work conducted at a university in Colombia that created an evaluation instrument based on the Academic Communities of Engagement (ACE) framework (Borup et al., 2020) to examine how well the institution was supporting the affective, behavioral, and cognitive (ABC) dimensions of engagement in its online and blended learning course offerings. This survey, the …

A Multi-Measure Approach For Lexical Diversity In Writing Assessments: Considerations In Measurement And Timing, Kelly Woods, Brett James Hashimoto, Earl K. Brown

Faculty Publications

Several researchers (e.g., Gebril & Plakans, 2016; Crossley & McNamara, 2012) have noted a relationship between lexical diversity (LD) and writing proficiency. Previous research has indicated that typical LD measures can account for as much as 44 % of variability in writing proficiency (Crossley et al., 2011). However, it remains unclear which of the numerous LD measures (or combination of measures) that exist best predict writing proficiency (e.g., McCarthy & Jarvis, 2010). The present study addresses these issues using scored writing assessment samples from 911 ESL students. LD was assessed with a battery of ten measures through the Python lexical-diversity …

The Critical Need For Human Capital Measurement Standards And Transparency In Healthcare, Heather Whiteman, Solange Charas, Hieu Bui, Lee S. Webster, James Gaskin

Faculty Publications

Despite long histories, the disciplines of healthcare performance analytics and human capital analytics followed parallel but separate tracks during the 19th and 20th centuries. Little has been done to integrate these two analytic disciplines to improve the delivery of medical care and the sustainability of healthcare organizations. Today, there is an increased demand for healthcare to meet the aging world population, spiraling healthcare costs, and a shortage of human resources to meet patient needs. It is imperative that healthcare professionals apply innovations to explore and optimize value from a combined discipline of healthcare human capital measurement and reporting.

Sample Size Matters In Calculating Pillai Scores, Joseph A. Stanley, Betsy Sneller

Faculty Publications

Since their introduction to sociolinguistics by Hay, Warren, and Drager [(2006). J. Phon. (Modell. Sociophon. Var.) 34(4), 458–484], Pillai scores have become a standard metric for quantifying vowel overlap. However, there is no established threshold value for determining whether two vowels are merged, leading to conflicting ad hoc measures. Furthermore, as a parametric measure, Pillai scores are sensitive to sample size. In this paper, we use generated data from a simulated pair of underlyingly merged vowels to demonstrate (1) larger sample sizes yield reliably more accurate Pillai scores, (2) unequal group sizes across the two vowel classes are irrelevant in …

Sociophonetics And Dialectology, Dominic Watt, Margaret E. L. Renwick, Joseph A. Stanley

Faculty Publications

In this chapter we explore how the investigation of phonetic detail in speech seen through a sociolinguistic lens can inform and enhance our understanding of dialectal variation in languages. We begin by examining how sociophonetics can be considered an offshoot of dialectology, later to mature into a free- standing discipline during the late twentieth century. We next discuss the reconvergence of sociophonetics and dialectology as it became clearer that the two approaches to the study of language variation are, in combination, greater than the sum of their parts, even if their agendas may place different emphases on what should be …

Interrelationships In Inventory Turnover Performance Between Supplier And Customer Firms, Joseph J. Henry, Peter Christensen, James C. Brau

Faculty Publications

Using inventory turnover to measure the efficiency of corporate inventory management, we perform econometric analyses to verify whether the inventory efficiency of a firm’s supply chain partners is a statistically significant driver of the firm’s own inventory efficiency. We test two mutually exclusive hypotheses. First, suppliers hold inventory on behalf of customers, effectively displacing inventory up the supply chain and resulting in a negative correlation between supplier and customer inventory turnover. Alternatively, inventory efficiency is integrated along the supply chain, resulting in a positive correlation between supplier and customer inventory turnover. Our bivariate and multivariate analyses of both firm- and …
