The Effect Of Gaming On Novice Pilots, Asia Douglas, Tristan Mcmichael

Symposium of Student Scholars

Global aviation is suffering pilot shortage, and by 2032, it is expected that international aviation will be 80,000 pilots short. Hence, there is an immediate need to identify ways to expedite pilot training. Researchers have found that gaming positively impacts cognition and hand coordination. Specifically, the abilities of people with expertise levels in video gaming have significantly improved performance scores in many flight simulators. However, these studies lack generalization due to the small sample size. This study investigates whether prior gaming experience impacts the flight performance of novice pilots using a large sample size, flight simulator, and eye-tracking metrics. We …

Actively Guided Cansats For Assisting Localization And Mapping In Unstructured And Unknown Environments, Cary Chun, M. Hassan Tanveer

Symposium of Student Scholars

When navigating in unknown and unstructured environments, Unmanned Arial Vehicles (UAVs) can struggle when attempting to preform Simultaneous Localization and Mapping (SLAM) operations. Particularly challenging circumstance arise when an UAV may need to land or otherwise navigate through treacherous environments. As the primary UAV may be too large and unwieldly to safely investigate in these types of situations, this research effort proposes the use of actively guided CanSats for assisting in localization and mapping of unstructured environments. A complex UAV could carry multiple of these SLAM capable CanSats, and when additional mapping and localization capabilities where required, the CanSat would …

Small-Separation Speckle Contrast Optical Spectroscopy For Intraoperative Assessment Of Parathyroid Glands Viability During Thyroid Surgery, Connor Berger

Symposium of Student Scholars

The parathyroid glands (PTGs) are often damaged during thyroid surgeries due to a lack of methods identifying PTGs and assessing their viability. Damage to PTGs can cause hypocalcemia, a deficiency of calcium in the body. This complication can lead to detrimental consequences with economic burden. The surgeon’s current method of viability assessment is qualitative and subjective. Our technical solution is to employ an optical technique called speckle contrast optical spectroscopy (SCOS) that noninvasively quantifies the blood flow index (Db) of biological tissues at deep tissue levels (>1cm). The goal of this project is to verify SCOS at small source-detector-separation …

Impact Of Cannabinoids On Human Neural Differentiation And Oxidative Stress Response, Emily Brothersen, Dillon Weatherston, Ashton Young, Bryan Gustafson

Fall Student Research Symposium 2022

Cannabinoids are a group of over 144 known compounds extracted from hemp species. Tetrahydrocannabinol (THC), the psychoactive compound in hemp, and the non-psychoactive cannabidiol (CBD) are the most commonly known and most well studied cannabinoids. As cannabinoids can be sold for medicinal or recreational purposes, it's important to understand the impact of these cannabinoids on the brain. To explore the effects of cannabinoids on neural development, undifferentiated SH-SY5Y human neuroblastoma cells were used as a model of fetal neurons. SH-SY5Y cells were fully differentiated in the presence of no cannabinoids, THC, and/or CBD and analyzed for any developmental differences. In …
