Fractals Exploration Through Computer Visualization, Sihui Wei

SACAD: Scholarly Activities

This project explores the generation and visualization of fractals using computational methods. Several well-known fractal structures, including the Koch Snowflake, Sierpinski Triangle, Mandelbrot Set, and Julia Set, were implemented using C++ and the SFML graphics library.

The study focuses on how simple mathematical rules, when applied recursively or iteratively, can produce highly complex and self-similar structures. For geometric fractals, recursive algorithms were used to subdivide shapes and generate patterns. For complex-plane fractals, iterative formulas were applied pixel-by-pixel to determine set membership and visualize escape behavior.

The results demonstrate that small changes in parameters, such as recursion depth or iteration count, …

A Computational Study Of Taylor Approximation, Sihui Wei

SACAD: Scholarly Activities

This project investigates the accuracy of Taylor approximation using computational methods. Taylor polynomials of degree 1, 3, and 5 were applied to the functions e^x, sin x, and ln⁡(1+x), all centered at x=0.

Using C++, we generated both numerical data and graphical visualizations to analyze the absolute error∣f(x)−Tn(x)∣. The results show that higher-degree polynomials provide better approximation near the expansion point, while the error increases as the distance from the center grows.

In addition, the study reveals that the effectiveness of Taylor approximation depends not only on the polynomial degree but also on the structure of the function. In particular, …

Behaviorally-Anchored Team Member Feedback In Undergraduate Learning: Linking Verbal Communication To Ai-Detected Emotional Expressions, Ryan Will, Brent J. Goertzen, Magdalene Moy, Jace Hesford

SACAD: Scholarly Activities

This study examines how undergraduate team members’ verbal communication behaviors are associated with the emotional expressions of their teammates during student project team interactions. Drawing on data from a semester-long, team-based undergraduate course, three key team meetings were video-recorded across the team life cycle. Verbal communication was analyzed using a systematic content analysis with an a priori codebook capturing emotionally relevant behaviors such as optimism, empathy, building bonds, developing others, service orientation, and task-focused communication. Nonverbal emotional expressions were assessed using AI-based facial expression analysis grounded in Facial Action Coding System research, generating average emotion scores for each team member. …

Validating Llm-Assisted Coding Of Student Leadership Teams For Formative Feedback, Jace Hesford, Magdalene Moy, Ryan Will, Brent Goertzen

SACAD: Scholarly Activities

Leadership education scholarship increasingly calls for direct assessment of leadership behaviors rather than reliance on proxy measures (Banks et al., 2023). This poster reports a validation study situated in a project-based leadership course at a midsized university. While teams meet regularly throughout the semester-long project, three meetings are digitally recorded, transcribed and analyzed to provide students with objective feedback based on the content of their communication. Team meetings are coded using an a priori framework grounded in emotional intelligence (Salovey & Mayer, 1990; Lee & Wong, 2017), with codes reflecting self-awareness, self-regulation, self-motivation, social awareness, and relational management as enacted …

Weaving With Color Theory, Clay Johnson

SACAD: Scholarly Activities

In Fall of 2026 I have been taking an Advanced Drawing class where we are making art with string. The emphasis so far has been to create weavings using different color theories and patterns. We have also tried different weaving techniques, using the Inkle Loom, tapestry loom, and the table loom. Using the different looms have been challenging but rewarding to gain new skills. Weaving in a drawing class helps us think outside of just the charcoal and paper, but how we can approach other art with the drawing techniques we have learned such as color theory.

Woven Color: Historical Uses Of Color Theory Woven Into Fiber Art Practice, Mary K. Greenwood

SACAD: Scholarly Activities

This semester-long project, created in Material Exploration, examines the use of historical color theory within contemporary fiber art to evoke emotion and narrative. Drawing from established color systems, artistic movements, and artist inspirations, the work explores how color relationships, such as harmony, contrast, and saturation, can communicate mood and meaning. Through experimentation with textile materials and processes, each piece integrates intentional color schemes to enhance storytelling through both visual and tactile elements. Ultimately, the project highlights how applying historical color theory within fiber art can deepen emotional resonance and connect traditional practices with contemporary expression.

Color Clash: When Opposites Create Harmony, Zachary Dean Esslinger

SACAD: Scholarly Activities

Opposites attract is usually the saying and the same can be said for colors. Complimentary colors are pairs directly opposite each other on the color wheel. Warm versus cool, bright versus high intensity these are things that stand out when these colors are paired together Red/Green, Yellow/Purple, Blue/Orange and subsequently any hues, values and tints can be used as well. complementary color pairs, but if looking at a color wheel there are twelve consisting of your three primary and the othernine coming from different hues.

The Effect Of Water Pollution In Kansas, Chaejun Park Chaejun Park, Jeanne Sumrall

SACAD: Scholarly Activities

Groundwater in Kansas shows significant nitrate contamination, with about 20% of samples exceeding the Environmental Protection Agency’s (EPA) safe drinking water limit of 10 mg/L. This indicates that a considerable portion of groundwater sources are affected by pollution levels high enough to pose potential risks to human health and environmental quality. High nitrate concentrations are strongly associated with agricultural activity and land-use patterns, particularly areas with intensive fertilizer application, irrigation, and livestock operations. In addition, more than half of all monitored wells show evidence of human influence, reinforcing the idea that nitrate contamination is largely driven by anthropogenic rather than …

From Books To Justice: Public Libraries Strengthening Legal Access Across Kansas, Lauren J. Franks, Ziwei Qi

SACAD: Scholarly Activities

Legal self-help centers across Kansas allow access to legal information for self-represented litigants in civil court cases. However, there is a lack of these centers in rural areas. In areas where this resource does not exist, libraries, which already serve as a trusted community-centered hub, can help provide legal information and resources. This project aims to identify best practices in increasing access to legal information and survey key staff including self-help center staff, court staff such as court clerks and judges, and librarians, to help inform our integration of legal self-help services into public libraries. By executing a short anonymous …
