Barrett, The Honors College Thesis/Creative Project Collection
Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.
Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Description
This Creative Project was carried out in coordination with the capstone project, Around the Corner Imaging with Terahertz Waves. This capstone project deals with a system designed to implement Around the Corner, or Non Line-of-Sight (NLoS) Imaging. This document discusses the creation of a GUI using MATLAB to control the Terahertz Imaging system. The GUI was developed in response to a need for synchronization, ease of operation, easy parameter modification, and data management. Along the way, many design decisions were made ranging from choosing a software platform to determining how variables should be passed. These decisions and considerations are discussed in this document. The resulting GUI has measured up to the design criteria and will be able to be used by anyone wishing to use the Terahertz Imaging System for further research in the field of Around the Corner or NLoS Imaging.

Description
Distinguishing between projectile and blunt force or sharp force trauma can be complicated by processes that result in fragmentation or loss of skeletal features. Postmortem processes that obscure skeletal features may result in the inability to properly determine the mechanism of trauma using morphology alone. The presence of gunshot residue (GSR) is indicative of a gunshot event and can be used to differentiate between etiologies of skeletal trauma. Primer GSR is composed of barium (Ba), antimony (Sb), and lead (Pb), which are vaporized during the firearm discharge and can be deposited in small quantities on surfaces within proximity of a gunshot event. Scanning Electron Microscopes with Energy Dispersive X-Ray Spectroscopy (SEM-EDX) have been used in the past to detect GSR on a variety of surfaces including bone. The purpose of this study is to determine the ability to detect GSR on bone tissue using SEM-EDX following warm-water maceration or decomposition.

Description
Forensic anthropologists rely on the validated sex determination methods that utilize post-cranial elements in adult remains, but, recently, research has been conducted to determine adult remain sex using just the skull. Similar research for sub-adult remains is lacking the robustness and validation that adult determination methods possess. This study utilized 20 crania measurements taken from CT scans of child patients with known sexes at the Phoenix Children’s Hospital to investigate if a sex determination method could be produced. The measurements were assessed with a t-Test, Linear Discriminant Analysis, and Principle Component Analysis to determine if sexual dimorphism was detectable and if the predictive model had discriminant power when the sample size was categorized by age. The results revealed that a few measurements were dimorphic, but were not statistically significant to determine the sex of a sub-adult outside of the sample population. Future investigations will remove age group classification to observe if this model can predict age.

Description
This study examines the utility of diagnostic CT scans as sources of data to quantify facial growth in children. Subadults often suffer facial trauma arising from a variety of circumstances. Pediatric surgeons are then confronted with devising surgical pre- and post-operative strategies that present numerous complications. One of these involves predicting how specific areas of a child's face will change with time. The proliferation of CT scans use in pre-operative planning throughout healthcare provides potential data for addressing many concerns, including those involving facial growth. To add to the burgeoning body of literature focusing on facial growth and provide insight anatomical variation this study used data derived from CT scans from Phoenix Children's Hospital. Quantitative data derived from CTs were used to examine normative growth and develop predictive equations that surgeons can use to visualize facial change for males and female patients.
