Designing And Evolving The Life Support System For Spacex Starship: Toward Closed-Loop Sustainability For Mars Missions, Frányerson R. López Ochoa
Designing And Evolving The Life Support System For Spacex Starship: Toward Closed-Loop Sustainability For Mars Missions, Frányerson R. López Ochoa
Discovery Day - Daytona Beach
The development of a robust Life Support System (LSS) is essential for enabling long-duration human spaceflight beyond Low Earth Orbit (LEO), particularly for missions to Mars. SpaceX Starship represents a next-generation spacecraft designed to support such missions; however, its Environmental Control and Life Support System (ECLSS) remains under active development. This work evaluates the current status of Starship’s LSS by analyzing publicly available data, NASA Human Landing System requirements, and heritage systems such as the International Space Station (ISS) ECLSS and Crew Dragon.

A Myoelectric Prosthesis Utilizing A Convolutional Neural Network And Signal Processing, Hope Lea, Katherine Clark, Francis Genco, Carolyn Ascha Richardson, Tobiah Rosser
Discovery Day - Daytona Beach
A Myoelectric Prosthesis Utilizing A Convolutional Neural Network and Signal Processing Commercially available myoelectric prostheses for transradial amputees utilize electromyography (EMG) sensors to observe electrical signals from superficial muscle contractions and control robotic fingers, yet often have flaws regarding adaptability and dexterity. These devices require users to learn awkward muscle patterns, as the EMG placement and gesture recognition does not consider how humans would normally think about moving their hand. Additionally, the number of available gestures is more limited, as the devices are threshold-based and do not sample enough muscles. This work seeks to address these issues by creating a …

Assessing Non-Thermal Plasma In Cutaneous Regeneration, Arden Rodriguez, Meliah Martin, Graeme Grainger, Arineh Shahbazi
Discovery Day - Daytona Beach
Chronic and acute wounds remain a significant clinical challenge, particularly in austere and resource-limited environments where access to advanced care is restricted. Non-Thermal Plasma (NTP) has emerged as a promising, non-invasive modality with reported antimicrobial and regenerative properties; however, its mechanisms of action and effects on human skin tissue require further characterization. The scope of this project is to engineer and utilize a 3D human skin epithelial model to evaluate the effects of NTP on wound healing. We will first build a 3D epithelial tissue model that will simulate human skin, followed by modeling and evaluation of wound pathology and …
Restoration And Instrumentation Of A Cantilever Beam Model Using Strain Gauge Measurement, Ana Paula Guevara
Restoration And Instrumentation Of A Cantilever Beam Model Using Strain Gauge Measurement, Ana Paula Guevara
Discovery Day - Daytona Beach
This project aims to restore and modernize an instructional cantilever beam model with a C‑shaped cross‑section used in Aerospace Structures courses, addressing the need for updated, hands‑on teaching tools that connect theoretical stress–strain concepts to real experimental data. The existing model, previously limited to qualitative demonstrations, is being rehabilitated and instrumented with a bonded strain gauge capable of detecting resistance changes under applied bending loads. These signals are processed through an Arduino‑based data acquisition system, which converts electrical resistance into strain values and displays them in real time on an LCD interface. The project’s objectives are to return the beam …
Simulating Pacemakers And Heartbeat Recovery Through Mathematical Modeling, Thomas Estrada, Jayla Edwards
Simulating Pacemakers And Heartbeat Recovery Through Mathematical Modeling, Thomas Estrada, Jayla Edwards
Discovery Day - Daytona Beach
Title: Simulating Pacemakers and Heartbeat Recovery Through Mathematical Modeling This study utilizes the Fitzhugh-Nagumo model to simulate cardiac electrical activity and the regulatory role of pacemakers through ordinary differential equations (ODEs). By defining the rate of change for membrane voltage, 𝑑𝑣/dt, and a recovery variable, 𝑑𝑤/dt, the model captures the heart's excitability and resting states. Central to the analysis is the stimulus current parameter, which represents the "kick" provided by a pacemaker to correct flatline conditions or weak heartbeats. Using Euler’s method for numerical integration, the research compares unstable cardiac rhythms against corrected periodic oscillations. Additionally, the project implements vector …
Dynamic Ankle Brace, Amulya Bajracharya
Dynamic Ankle Brace, Amulya Bajracharya
Beyond: Undergraduate Research Journal
The dynamic ankle brace is a 3D printed brace with geometric mesh patterns and two layers of compression sleeves. The goal of the brace is to design a comfortable slim fit ankle brace that is competitive with current ankle support braces on the market. The geometric braces provided similar levels of inversion and eversion as market braces using different sizing. The braces were tested with a custom built testing rig and human participants proving 3d printed braces are flexible yet durable. User feedback indicates users desired stronger stitching of the braces overall.
How Does Robotic Surgery Influence Communication, Leadership, And Team Outcomes? A Multimethod Examination., Jordan E. Rogers
How Does Robotic Surgery Influence Communication, Leadership, And Team Outcomes? A Multimethod Examination., Jordan E. Rogers
Doctoral Dissertations and Master's Theses
The practice of delivering surgical care has evolved to be less invasive to the patients undergoing surgery. Minimally-invasive surgery can be practiced through traditional laparoscopic methods as well as with robotic technology that displaces the surgeon from the operating table. Robotic surgery has been cited to be safer and more effective than traditional laparoscopic surgery; however, little research has endeavored to investigate the role of surgical modality upon aspects of teamwork. This dissertation contributes to the human factors and teamwork literature by evaluating how surgical modality may influence communication, shared leadership, and team outcomes. Multiple methods were employed to study …
Laboratory Development Of A Self-Powered Fontan For Treatment Of Congenital Heart Disease, Arka Das
Laboratory Development Of A Self-Powered Fontan For Treatment Of Congenital Heart Disease, Arka Das
Doctoral Dissertations and Master's Theses
Around 8% of all newborns with a Congenital Heart Defect (CHD) have only a single functioning ventricle. The Fontan operation has served as a palliation for this anomaly for decades, but the surgery entails multiple complications and survival rate is less than 50% by adulthood. A rapidly testable novel alternative is proposed by creating a bifurcating graft, or Injection Jet Shunt (IJS), used to “entrain” the pulmonary flow and thus provide assistance while reducing the caval pressure. A benchtop Mock Flow Loop (MFL) is configured to validate this hypothesis. The MFL is based on a Lumped-Parameter Model (LPM) of the …

Under The Needle: Ergonomic Issues With Lethal Injection Protocols, Gabriella Hancock
Human Factors and Applied Psychology Student Conference
The institution of capital punishment represents one of the most contentious issues affecting societies today; and while the practice is only implemented in 58 countries, the controversy affects the world at large as over 60% of the human population lives in nations that condone the death penalty (Hali, 2015). In the United States, people who support capital punishment believe the practice to be an effective crime deterrent for potential criminals and therefore a prospective protective measure for law abiding citizens. Moreover, advocates defend their position by forwarding the argument that executions are ‘humane’; that use of lethal injection ensures that …
