In Pipe Biofilm Removal System, Caroline White, Abe Muldrow, Jack Catalano, Brendan Thomas Palmer

Mechanical Engineering

In many drinking water systems, biological build-up can accumulate over time and create contamination resistant to traditional chemical flushing techniques, thus creating systems that must be flushed constantly to be considered safe. The team analyzed how this biological build up occurs, the current methods of removal, and thought about different ways to remove this ENGR 459-03 7 biological buildup without further damaging the health of the water system. To do this, we preformed extensive academic research about how biofilm builds up in water systems, examined any existing products that remove containments from water systems, and developed a solution capable of …

A User-Centric Continuous Authentication Modality Evaluation And Selection Scheme, Bharath R. Senthilkumar

Master's Theses

One of one-time authentication’s most prominent vulnerabilities is the possibility of lunchtime attacks. In such scenarios, an adversary could exploit an unattended device with an active session and no measures are taken to prevent them from committing malicious acts. To address this issue, continuous authentication is utilized by continuously verifying whether an individual is a device’s rightful owner through various modalities, with data sourced from sensors. In the current body of research within this rising domain, various single-modal and multi-modal continuous authentication systems exist, that focus on employing unique combinations of modalities and improving existing supervised learning models used to …

Short Arc Initial Orbit Determination For Leo Objects And The Impact Of Observation Eelevation On Predictive Accuracy, Alexis Digregorio

Master's Theses

The expansion of space activities has led to an increase in congestion. With this increase, there has been a growing emphasis on the importance of space situational awareness. Without it, the space environment can become hazardous, with increasing threats of collision and debris generation. As the utilization of space continues to grow, effective methods for tracking objects to maintain situational awareness must also be considered. One approach to tracking objects in space involves a series of steps, including optical observations and orbit estimations using initial orbit determination methods, followed by additional observations and continuous tracking. However, a challenge with this …

Team F16: Autonomous Research Plane, Andrew Sugamele, Andrew Whitacre, Nicholas Toal, Cole Bushur

Mechanical Engineering

The autonomous research plane is a remote-controlled plane used for both in-flight data collection and to explore new manufacturing methods for Design Build Fly, an engineering club on campus. The club does not have the resources or time to implement data collection for their competition plane, so we built a plane in parallel, following similar rules to mimic the work and schedule that the club would use during their season. We first did research and analysis to determine the structure of the plane, geometry of wings, sizing of the tail, and what airfoil to choose. The manufacturing process included making …

The Wall Group, Richard Antablin, Sara Engmyr, Michelle Griffith, Jora Leigh, Jesse Rainsdon

Architectural Engineering

This project aimed to design and construct an art wall in Poly Canyon to deter graffiti on existing structures and provide a designated area for student expression. However, after prolonged iterative revisions, it became evident that the project was significantly behind the original timeline.

It was recommended that the wall proposal be submitted for future student implementation. Instead of constructing the wall, an alternative course of action was proposed: restoring an existing structure in Poly Canyon to provide the desired hands-on experience.

After careful consideration, the Techite Bridge was selected for restoration. The proposed plan involves thorough cleaning, repairing chipped …

Examining The Impact Of Journalism On The Comprehensibility And Accessibility Of Scientific Literature, Izabella L. Slosberg

Journalism

This study investigates the comprehensibility and accessibility of scientific papers compared to scientific journalism articles. Fifty articles were tested in pairs of two (one scientific journal article and one corresponding scientific journalism article), and ChatGPT 4.0 was used to create a comprehensibility scale ranging from 0-100%, designed to assess the percentage of people in California over the age of 18 who could understand each article. Each article was evaluated three times using the curated scale, and the results were thoroughly evaluated. The differences in comprehensibility between scientific journalism articles and scientific journalism articles along with the impact of the scientific …

Expanding Learn By Doing: Creating A Culture Of Extracurricular Lab Work In The Graphic Communication Department, Miriam Gabai, Isis Dominguez

Graphic Communication

The existing Graphic Communication (GrC) curriculum immerses students in print production through hands-on labs, exposing them to a variety of industrial machinery.

However, outside the context of required labs, students will rarely use the department’s equipment, which is a lost learning opportunity.

This project proposes exploring opportunities for students to use machinery outside the context of required classes, in order to both foster familiarity with industry tools and generate new industry knowledge. The aim is to research and develop a plan for implementing a program that helps to encourage students to further develop skills and pursue research projects using department …

The Challenges Of Building A Mass Timber Single-Family Home: A Case Study, Avery Emma Onan

Construction Management

This case study explores the various challenges faced by those involved in the pre-construction and construction of a mass timber, single-family home in Central Texas. Using semi-structured interviews, a subcontractor, an owner, a manufacturer, and two construction managers were questioned about their specific challenges with the build. These challenges were solely related to the use of mass timber on the project. In recent years in the United States, mass timber has become an increasingly desired building material to use in a commercial and multi-family residential context. Due to limited information and builder inexperience using mass timber in a single-family homebuilding …
