Climate Prediction As An Adaptive Force-Multiplier: Reasons For Hope In A Rapidly Changing World, Matthew D. Laplante

All Graduate Theses and Dissertations, Fall 2023 to Present

It's not unreasonable to feel pessimistic about our future under climate change. But "believing the science" doesn't require you to accept that we are headed toward apocalypse. It is true that human-caused climate change is real, it is underway, and our societies face many increased risks because of it. But that's just part of what climate science tells us about our future world. This same field is responsible for the recent and rapid development of tools and techniques that permit the identification of patterns in our oceans and atmosphere that will aid us in making increasingly accurate predictions about climate—the …

High-Throughput Phenotyping Of Early Generation Small Grains Breeding Lines To Indirectly Select For Grain Yield, Dalton Jones

All Graduate Theses and Dissertations, Fall 2023 to Present

In small grains breeding programs, breeders aim to develop better varieties by selecting for important traits like grain yield. However, it takes many years before yield can be measured because several generations of selection are required to fix lines and increase sufficient seed for yield measurements. This process can be slow and expensive

High-throughput phenotyping (HTP) is a modern approach that can increase breeding efficiency by leveraging technology to quickly measure secondary traits which can be used to indirectly select for important traits in crop plants. For example, researchers can use cameras on unmanned aerial vehicles (UAVs, i.e., drones) to …

Influence Of Physical Properties Of Fat On Product Quality, Shelf-Life And Consumer Acceptance Of Chocolate-Coated Products, Audrey Lidgard

All Graduate Theses and Dissertations, Fall 2023 to Present

In chocolate-coated products, oil migration in fats can lead to chocolate softening, filling hardening, discoloration, and lower consumer acceptance. This study examined three different fats (soy- palm-, and palm-kernel (PK) based), crystallized under different conditions (cooling rate and use of high intensity ultrasound (HIU)) to examine how the crystallization conditions impact the physical properties of confectionery products. These conditions produced fats with high and low oil binding capacities (OBCs); the ability of crystal networks to entrap liquid oil. Model systems were created to examine measurable quality degradation and consumer acceptance of chocolates placed in contact with the fats; one with …

Investigating Changes In Hydroclimate, Land Cover, And Evapotranspiration Across The Great Salt Lake Basin And Its Major Subbasins, Bhuwan Ghimire

All Graduate Theses and Dissertations, Fall 2023 to Present

The Great Salt Lake (GSL) is a lake of environmental and economic importance for Utah, and in recent years lake levels have declined to critically low levels. The lake level is dependent on the balance between the inflow and outflow. Inflow into the lake is governed primarily by the streamflow originating from the Bear, Weber and Jordan River basins (GSL subbasins), direct precipitation over the lake and groundwater entering into the lake. The GSL is a terminal lake, with outflow via evaporation from the lake.

In this study, we examined hydrologic processes within the river basins that relate to streamflow …

Describing Functionality In Natural Language May Improve Decomposition Behaviors, Matthew R. Burns

All Graduate Theses and Dissertations, Fall 2023 to Present

Problem decomposition—the ability to break complex problems into simpler parts—is a critical skill for computer programming that many beginning students struggle to develop. This research examines how using natural language to describe program functionality can help students develop better problem-solving approaches.

We created a tool called ”Natural Language Functions” (NLFs) that allows students to write descriptions of what they want their code to do in plain English, which then generates working Python functions. We studied how students used this tool compared to students who solved programming problems in traditional ways.

Our findings show that students who used the NLFs tool …

Advancing Multi-Agent Robotics Simulations Through Heterogeneous Reinforcement Learning In Isaaclab, Jacob R. Haight

All Graduate Theses and Dissertations, Fall 2023 to Present

Robots increasingly operate in collaborative teams across domains such as search-and- rescue, warehouse automation, and autonomous driving—scenarios that demand advanced coordination strategies enabled by multi-agent reinforcement learning (MARL). However, existing simulation frameworks often struggle to balance realism, speed, and scalability, especially when supporting diverse, heterogeneous robot teams. This research extends Isaac Lab, a high-performance robotics simulator, by integrating heterogeneous-agent reinforcement learning (HARL) capabilities. The result is a flexible and GPU-accelerated platform for training both homogeneous and heterogeneous robot teams in complex, physics-based environments. These enhancements significantly narrow the gap between simulation and real-world deployment for multi-robot systems.

Motherhood Within The Patriarchal Family: An Analysis Of “Frankenstein” And “The Scarlet Letter”, Yasamin Osqueezadeh

My question the became: Can an affordable, reliable airflow sensor system be designed …

Impacts Of Reef Fish Length On Foraging Radius: Exploring Behavioral Patterns Within A Patch Reef Ecosystem, Kilia Brawand

Undergraduate Honors Capstone Projects

Reef fish exhibit various behaviors upon the Great Barrier Reef. One of these behaviors includes that of limiting their grazing distances from a patch reef refuge to a certain maximum distance in order to avoid predators. This is defined as a ‘foraging radius’ or ‘margin of safety’. This ‘foraging radius’ varies among fish due to many factors- including species, morphology, ontogenesis, habitat complexity, and importantly: speed. Quicker fish can outswim predators to safety more efficiently than slower fish, and can therefore afford to travel farther distances to forage. Speed varies among fish for a number of reasons, including fish size …

Moments In The Making, Paige M. Harper

All Graduate Reports and Creative Projects, Fall 2023 to Present

Gathering around a table with good company, sharing stories and food, creates lasting memories. These moments of warmth, laughter, and connection stay with us long after a meal is over. These experiences are the driving force that inspire the vessels | create. These vessels serve as conduits for connection, helping to shape and enhance the shared experience. These objects are not only individual pieces, but also components of broader compositions. I consider how they are related in space. Using repetition, contrast, proportion, and negative space, I strive to create cohesive visual experiences that invite curiosity.

Exploring The Potential Of Exit Tickets As Formative Assessments Of Student Affect, Umar Shehzad, Mimi Recker, Jody Clarke-Midura

Publications

This study investigates the use of exit tickets as formative assessments in math-integrated computer science (CS) lessons for grade 5 students. Exit tickets are brief surveys administered immediately after instructional activities. Using structural equation modelling (SEM), we analysed data from 1,067 students to examine the reliability and validity of exit tickets in predicting summative pre/post survey results. The study found that the exit ticket responses consistently assessed student affect at two administration points, meeting strict measurement invariance criteria (χ2(21) = 1.34, p = 1.00). Confirmatory factor analysis revealed that exit tickets predicted student self-efficacy and interest in CS, which are …

A Model Of Changeover Behavior In Concurrent Schedules Of Reinforcement, Matias A. Avellaneda

All Graduate Theses and Dissertations, Fall 2023 to Present

Animals in the wild have access to a variety of food sources, and they must allocate their time between them in an efficient manner. This requires deciding when to depart from the source currently being exploited to travel to a different one. A general model of this decision process can be derived from three assumptions well supported by the learning literature. The first one is the so-called matching law, which says that the proportion of time allocated to any one behavior equals the proportion of total value obtained from that option. The second one is that the dwell times (i.e., …
