Nucleic Acid Detection Of Live Pathogens On Contaminated Foods, Simerdeep Kaur, Mohit Verma

Graduate Industrial Research Symposium

The goal is to develop a point-of-care biosensor for the detection of live pathogens contaminating beef products. Biosensing of live pathogens is based on isothermal amplification of nucleic acid on a paper-based device. A colorimetric dye is employed as an indicator of the amplification product for visual result. The assay incorporates a compound Propidium monoazide (PMA) that makes the DNA from dead cells inaccessible for amplification. This approach is especially applicable for pathogens that can enter a viable but non-culturable state (VBNC).

High density sampling of row cropping systems can enable a variety of agronomic research that is currently too labor intensive to feasibly pursue by hand. While aerial drones are commonly used to collect field data, there are numerous measurements of interest that require sensors deployed under the crop canopy. This project examines the development of a robust autonomous rover (OSCAR) that can travel through rows of corn throughout the growing season. OSCAR has a 22” wheelbase with differential steering allowing it to navigate through corn rows without damaging the plants. OSCAR is equipped with an RTK GNSS module and stereo …

Fuzzy Dynamic Gait Pattern Generation For Real-Time Push Recovery Control Of A Teen-Sized Humanoid Robot, Li-Fan Wu

Graduate Industrial Research Symposium

A fuzzy dynamic gait pattern generator, which allows a teen-sized humanoid robot to generate, in real-time, a suitable gait pattern when it is hit by an unexpected force, is proposed in this paper. Conventional gait pattern generators usually utilize the ideal Zero Moment Point (ZMP) to plan the trajectory of the Center of Mass (CoM), along with a cycloid to generate steps. However, pre-planned gait patterns cannot deal with unexpected situations, especially instances when the robot experiences an unknown force. Therefore, we propose a dynamic gait pattern generator that leverages the Virtual Force Linear Inverted Pendulum Model (VFLIPM) to adjust …

Identifying Non-Traditional Slippery Sequences Associated With Translational Frameshifts, Aaron J. Gin, Kari Lynn Clase

Graduate Industrial Research Symposium

Genetic frameshifts are a mutation in which
a nucleotide skip leads to a shift in the
reading frame. In viruses, these frameshifts
can be programmed using a slippery
sequence to bypass the stop codon
associated with the initial protein. This
allows for variable control of protein
expression. In bacteriophages, translational
frameshifts have been identified but only a
few have been proven experimentally. Using
experimental data and comparative
genomics, non-traditional slippery
sequences can be identified as assisting in
controlling the protein coding throughout
viruses. Novel slippery sequences can aid in
the understanding of protein expression in
biological environments and further the …

Thermally Treated To Perfection: Enhancing Wood Color And Properties With Surface Thermal Treatment, Jue Mo, Dipesh Tamboli, Eva Haviarova

Graduate Industrial Research Symposium

Darker-colored wood species usually have higher
values, many of which are endangered and under
protection. Chemical stains and finishes might also
achieve similar color shades, but customers prefer
non-chemical alternatives. Thermal treatment (TT)
is one of the low-toxicity choices. It could produce
darker shades and enhance some material
properties but requires a large initial investment
and is time-consuming. This study aimed to
evaluate a new type of TT: Surface Thermal
Treatment (STT). White Ash, Yellow Poplar, and Red
Oak were selected and treated on a heated press
at varying temperatures and times. Artificial Neural
Network (ANN) was employed to model …

Enzyme-Treated Yeast Fed To Coccidia-Challenged Broiler Chickens, Emmanuel O. Alagbe, Hagen Schulze, Olayiwola Adeola

Graduate Industrial Research Symposium

There is a growing search for natural feed additives to alleviate the deleterious effects of coccidia infection in poultry. Research has shown that may serve as healthier alternatives to coccidiostats.

This study aimed to investigate the effect of enzyme-treated yeast (EY) on the performance, nutrient digestibility, intestinal morphology, and health of coccidia-challenged broiler chickens. 480 broiler chickens were allocated to 3 corn-soybean meal-based experimental diets with increasing concentrations of EY (0, 1, or 2 g/kg). Dietary EY enhanced nutrient utilization and augmented intestinal development in broiler chickens. However, dietary EY did not completely attenuate the adverse effects of a coccidia …

The Next-Gen Crop Nutrient Stress Identification With High-Precision Sensing Technology In Digital Agriculture, Zhihang Song, Ziling Chen, Xing Wei, Jian Jin

Graduate Industrial Research Symposium

Crop yields are facing significant losses from nutrient deficiencies. Over-fertilizing also has negative economic and environmental impacts. It is challenging to optimize fertilizing without an accurate diagnosis. Recently, plant phenotyping has demonstrated outstanding capabilities in estimating crop traits. As one of the leading technologies, LeafSpec, provides high-quality crop image data for improving phenotyping quality. In this study, novel algorithms are developed for LeafSpec to identify crop nutrient deficiencies more accurately. Combined with UAV system, this technology will bring growers a robust solution for fertilizing diagnosis and scientific crop management.

Stellar Atmosphere Models For Select Veritas Stellar Intensity Interferometry Targets, Jackson Ladd Sackrider, Jason P. Aufdenberg, Katelyn Sonnen

Beyond: Undergraduate Research Journal

Since 2020 the Very Energetic Radiation Imaging Telescope Array System (VERITAS) has observed 48 stellar targets using the technique of Stellar Intensity Interferometry (SII). Angular diameter measurements by VERITAS SII (VSII) in a waveband near 400 nm complement existing angular diameter measurements in the near-infrared. VSII observations will test fundamental predictions of stellar atmosphere models and should be more sensitive to limb darkening and gravity darkening effects than measurements in the near-IR, however, the magnitude of this difference has not been systematically explored in the literature. In order to investigate the synthetic interferometric (as well as spectroscopic) appearance of stars …

We previously examined these factors with participants approximately one year into the pandemic from March to May 2021 (Koner et al., 2022). The current study explored these same music educators' stressors one year later, from March to April 2022, specifically exploring the research questions: (1) how do music educators describe the impact on their students’ learning and creating music through the COVID-19 pandemic; and (2) how have music educators professionally navigated an academic school year …

Preservice And Beginning Teachers’ Perceptions Of Healthy Musicianship, Carla Salas-Ruiz, Ann Marie Stanley, Joshua Burgos

Visions of Research in Music Education

Research on instrumental music majors is an important subset of performance injury literature (Barton, et al., 2008, Brandfonbrener, 2009). Musculoskeletal problems, physical and mental stress, and performance anxiety are common (Bernhard, 2005, 2020; Guptil, et al., 2005; Steinmetz, et al., 2012). Consequently, “healthy musicianship” (Taylor, 2016) is a growing area of interest within schools of music. Preservice music teachers need tools to maintain mental and physical wellness. They also need to learn to guide future students in healthy practices. Understanding how preservice teachers acquire pedagogical content knowledge in healthy musicianship is important: their approach to musical performance issues will influence …

The marginalization of women in engineering is a persistent problem. The overall goal of our collaborative project was to promote interest and participation in science, technology, engineering, and mathematics (STEM), particularly for high school girls. We took an action research approach with a local high school science teacher to develop, implement, and research the impact of a classroom-based intervention designed to encourage growth mindset and STEM self-efficacy beliefs using mixed methods. We analyzed pre- and postsurvey data collected using a control-treatment design to determine the impact of the intervention on high school boys’ and girls’ self-efficacy and mindset beliefs. We …

Optimal Monohedral Tilings Of Hyperbolic Surfaces, Leonardo Digiosia, Jahangir Habib, Jack Hirsch, Lea Kenigsberg, Kevin Li, Dylanger Pittman, Jackson Petty, Christopher Xue, Weitao Zhu

Rose-Hulman Undergraduate Mathematics Journal

The hexagon is the least-perimeter tile in the Euclidean plane for any given area. On hyperbolic surfaces, this "isoperimetric" problem differs for every given area, as solutions do not scale. Cox conjectured that a regular k-gonal tile with 120-degree angles is isoperimetric. For area π/3, the regular heptagon has 120-degree angles and therefore tiles many hyperbolic surfaces. For other areas, we show the existence of many tiles but provide no conjectured optima. On closed hyperbolic surfaces, we verify via a reduction argument using cutting and pasting transformations and convex hulls that the regular 7-gon is the optimal n-gonal tile of …

Strong Recovery In Group Synchronization, Bradley Stich

Rose-Hulman Undergraduate Mathematics Journal

The group synchronization problem is to estimate unknown group elements at the vertices of a graph when given a set of possibly noisy observations of group differences at the edges. We consider the group synchronization problem on finite graphs with size tending to infinity, and we focus on the question of whether the true edge differences can be exactly recovered from the observations (i.e., strong recovery). We prove two main results, one positive and one negative. In the positive direction, we prove that for a sequence of synchronization problems containing the complete digraph along with a relatively well behaved prior …

The Determining Number And Cost Of 2-Distinguishing Of Select Kneser Graphs, James E. Garrison

Rose-Hulman Undergraduate Mathematics Journal

A graph $G$ is said to be \emph{d-distinguishable} if there exists a not-necessarily proper coloring with $d$ colors such that only the trivial automorphism preserves the color classes. For a 2-distinguishing labeling, the \emph{ cost of $2$-distinguishing}, denoted $\rho(G),$ is defined as the minimum size of a color class over all $2$-distinguishing colorings of $G$. Our work also utilizes \emph{determining sets} of $G, $ sets of vertices $S \subseteq G$ such that every automorphism of $G$ is uniquely determined by its action on $S.$ The \emph{determining number} of a graph is the size of a smallest determining set. We investigate …

Recognition Of Design Failure By Fourth-Grade Students During An Engineering Design Challenge, Ron K. Skinner, Danielle B. Harlow

Journal of Pre-College Engineering Education Research (J-PEER)

The practice of persisting and learning from design failures is essential to engineering design and offers unique ways of knowing and learning for K-12 students. To understand how students engage in the practice of persisting and learning from design failures, we must first understand how, if at all, they recognize that a design failure has occurred. We studied a classroom of fourth-grade students engaged in an engineering design challenge and examined the ways in which design failure occurred and how students recognized, neglected to recognize, or misinterpreted design failure. We found that, in addition to anticipating failure, conducting fair tests, …

Is God A Magician Or Scientist?, Sarah Palmer, Josh Oliver, Jessica Abele, Jamie Jensen Ph.D

Library/Life Sciences Undergraduate Poster Competition 2023

There is a body of evidence in biology education indicating that most American undergraduate students believe evolution acceptance to be an aesthetic position (1). Introductory biology professors at Brigham Young University have gathered essays written by students entering the class on their experiences with evolution since about 1980. Because BYU is a religious college, most of these students wrote about how their understanding of God impacts their acceptance of evolution. To learn whether student perceptions of God have changed in the past 30 years, we qualitatively analyzed these essays from a cohort of students in 1992 and another cohort of …

Teachers’ Perceptions Of Policies And Practices Of Lgbtq-Inclusive Curriculum In Rural Appalachian High School English Language Arts Classes, Dawn J. Viles

Ed.D. Dissertations

Lesbian, Gay, Bisexual, Transgender, Queer students were a vulnerable population in rural Appalachian high schools. Minority high school students, specifically those who identified as Lesbian, Gay, Bisexual, Transgender, Queer, who saw themselves reflected in practices and curriculum increased their academic performance, felt safe, and developed stronger empathy for others. Traditionally, English Language Arts teachers had power to select literary works and supplemental materials they deemed important for their students; however, local, district, and state stakeholders and policymakers influenced curricular choices in English Language Arts classrooms more directly than had occurred in the past. Further marginalizing Lesbian, Gay, Bisexual, Transgender, Queer …

Tunable, Reconfigurable, And Programmable Acoustic Metasurfaces: A Review, Ali Zabihi, Chadi Ellouzi, Chen Shen

Henry M. Rowan College of Engineering Departmental Research

The advent of acoustic metasurfaces (AMs), which are the two-dimensional equivalents of metamaterials, has opened up new possibilities in wave manipulation using acoustically thin structures. Through the interaction between the acoustic waves and the subwavelength scattering, AMs exhibit versatile capabilities to control acoustic wave propagation such as by steering, focusing, and absorption. In recent years, this vibrant field has expanded to include tunable, reconfigurable, and programmable control to further expand the capacity of AMs. This paper reviews recent developments in AMs and summarizes the fundamental approaches for achieving tunable control, namely, by mechanical tuning, active control, and the use of …
