The Dual Boundary Complex Of The Moduli Space Of Cyclic Compactifications, Toby Anderson

HMC Senior Theses

Moduli spaces provide a useful method for studying families of mathematical objects. We study certain moduli spaces of algebraic curves, which are generalizations of familiar lines and conics. This thesis focuses on, Δ^(r,n), the dual boundary complex of the moduli space of genus-zero cyclic curves. This complex is itself a moduli space of graphs and can be investigated with combinatorial methods. Remarkably, the combinatorics of this complex provides insight into the geometry and topology of the original moduli space. In this thesis, we investigate two topologically invariant properties of Δ^(r,n). We compute its Euler characteristic and …

Are Academia And Industry Listening To Each Other? A Citation Analysis Of Ux Research Methods Resources, Abigail Bakke, Leonard Dibono

English Department Publications

Technical and Professional Communication (TPC) has been facing concerns of viability, in both its relationship with industry and its ability to build a relevant and valid body of research. TPC’s disconnection with industry may be reflected in its relationship to UX as well, despite both fields’ shared values. To better understand how TPC and User Experience (UX) are relating to each other, we conducted a citation analysis of a sample of SIGDOC papers and a sample of Nielsen Norman Group (NN/g) practitioner articles focused on research methods. The SIGDOC papers tended to cite TPC sources, while the NN/g articles cited …

Survey Of Memory Consolidation Techniques For Video Question Answering, Matthew Couts, Pha Nguyen, Khoa Luu

Inquiry: The University of Arkansas Undergraduate Research Journal

Video Question Answering (VideoQA) is a field of research focused on developing models that can engage in natural conversations with humans about the content of videos. Currently, the most successful approaches involve analyzing videos frame-by-frame, which is computationally and memory-intensive. To imitate human memory, the Atkinson-Shiffrin memory model can formulate the machine’s video understanding capability through Vision-Language Models. Reducing the number of frames processed by the model is a crucial operation in this approach category and can be handled by a memory consolidation algorithm. The memory consolidation algorithm should be able to determine the keyframes to transfer from short-term to …

Education for Sustainable Development (ESD) is crucial for equipping individuals with the competences needed to address the pressing social, economic, and environmental challenges of our time. Despite the recognized potential of service-learning in cultivating competences that can promote sustainable development, there is a lack of empirical research exploring the development of these competences among students. Hence, this study examined the effectiveness of service-learning as a pedagogical approach to ESD in fostering essential competences among students. The research involved 43 groups of students, who engaged in addressing various sustainable development issues through service-learning. A thematic analysis of students’ written reflections revealed …

Regis University Student Publications (comprehensive collection)

Thelephorales fungi are considered important ectomycorrhizal fungi (EMF) in forest ecosystems, yet the patterns of diversity and distribution and the processes that shape them remain poorly understood. This study aims to address this research gap by conducting an exploratory analysis of Thelephorales fungi in soil and litter across various habitat types and environmental characteristics. To do so, we used data collected and synthesized by the Climush project, a multi-year, systematic sampling of macrofungal diversity across North America, that aims to assess sexual (sporocarp and spore trap data) and asexual (soil and endophyte metabarcode data) diversity and distribution in relation to …

Ms Environmental Biology Capstone Project, Denise Corona

Regis University Student Publications (comprehensive collection)

Land-use change (LUC) is a key driver of biodiversity loss, altering the structure and function of ecosystems through human activities such as urbanization and agriculture. This change has led to habitat loss and fragmentation, resulting in the rapid decline of avian populations globally. Wildlife rehabilitation centers are the primary responders for injured birds and their records provide valuable data to monitor potential factors impacting bird populations. However, these datasets are underutilized in research. This study examined how LUC in the Front Range affects the likelihood and circumstances of admission of injured birds to the Rocky Mountain Wildlife Alliance (RMWA) in …

Simulation Studies Of Topological Defect Behavior In Rank-2 Anti-Symmetric Tensor Fields, Wyatt Carbonell

Physics, Astronomy and Geophysics Honors Papers

Lorentz-violating models are a class of theories in which a fundamental field breaks the underlying Lorentz symmetry of a system action by assuming a nonzero vacuum expectation value. In this work, we consider a model which achieves such a Lorentz violation through a rank-2, anti-symmetric tensor field. We present a derivation of the equations governing the time evolution of this tensor field, the specifications of a program capable of numerically simulating this evolution through the solving of differential equations, evidence for the success of our simulation in accurately representing the model, and evidence against the physical viability of such a …

Computing An Image Of Objects Hiding Behind A Black Hole, Shanon Harding

Undergraduate Review

Gravitational lensing is the bending of light rays around a black hole. The goal of this project was to produce a computer code that would model light rays coming from a grid of objects set behind a rotating black hole. Using these light rays, we produced an image illustrating how this background of objects would appear to an observer on Earth. This was done by creating a MATLAB code to model the paths of multiple light rays at a time. This code was then used to help check and correct a C++ code that produced an image. Over the semester, …

The Grand Ethiopian Renaissance Dam: Impacts At Play For Egypt, Chemp Carpenter

Undergraduate Review

As fresh water is required for human survival, access to water resources greatly benefits human societies. Over the last 50 years, there has been an increase in dam construction around the world. Dams are built to store water and regulate a river's flow, as well as to raise the water level upstream to facilitate flow into a channel. Furthermore, they offer numerous benefits, including controlling floods, improving irrigation, acting as storage, being a water supplier, and generating electricity. Nonetheless, dams also pose serious hazards. Ethiopia began construction on a 6000-megawatt dam called The Grand Ethiopian Renaissance Dam (GERD) in 2011, …

Correlation Of Geochemical Zones In Great Onyx Cave, Mammoth Cave National Park, To Surficial Geological Units, William Strehl

Mahurin Honors College Capstone Experience/Thesis Projects

Cave passages in Great Onyx Cave, developed within the Girkin and Ste. Genevieve Limestones of Mammoth Cave National Park, contain a variety of secondary features on cave walls, including speleothems such as stalactites, stalagmites, and flowstone, evaporite minerals, and dissolution features such as pits and domes. What secondary features are present on the walls of a cave passage depends on the flow and geochemistry of capillary water that has interacted with the cave passage. In the Mammoth Cave aquifer, five distinct geochemical zones have been broadly defined and each typically contains a particular set of secondary features. Geochemical zonation in …

Machine Intelligence With Associative Memory And Event-Driven Transaction History, Rao Mikkilineni, W. Patrick Kelly

Barowsky School of Business | Faculty Scholarship

Digital machine intelligence has evolved from its inception in the form of computation of numbers to AI, which is centered around performing cognitive tasks that humans can perform, such as predictive reasoning or complex calculations. The state of the art includes tasks that are easily described by a list of formal, mathematical rules or a sequence of event-driven actions such as modeling, simulation, business workflows, interaction with devices, etc., and also tasks that are easy to do “intuitively”, but are hard to describe formally or as a sequence of event-driven actions such as recognizing spoken words or faces. While these …
