The Secret Of Smerdyakov, Abigail M. Munzar
The Secret Of Smerdyakov, Abigail M. Munzar
Global Tides
This paper analyzes the mysterious character of Pavel Smerdyakov from Dostoevsky’s novel, The Brothers Karamazov, by examining his loveless upbringing, motives for murdering Fyodor Karamazov, and his final conversations with Ivan Karamazov, to argue that Smerdyakov committed suicide out of guilt from his crime. Smerdyakov may have had a potential conversion to Christianity which would have triggered an identity crisis in which he was tormented between accepting Christ’s love and hanging on to his lifelong hatred. Thus, he would have committed suicide out of remorse from his sin like the biblical Judas and an inability to choose between conversion or …

Shoulder Ligament Instability In A Nuclear Watch Engineer: How Poor Equipment Conditions Lead To Increased Risk Of Musculoskeletal Disorder, Brianna Broderick
Student Research Symposium (SRS)
This case study focuses on a nuclear watch engineer, referred to as BC, and how his working conditions coupled with his pre-existing shoulder ligament instability lead to risk of physical injury. Analysis was done through two musculoskeletal disorder risk assessments and interviews focusing on background and psychosocial factors in the workplace. The main risk was associated with the plant’s equipment: poor placement led to shoulder, neck, and upper limb strain, and lack of maintenance led to strain via more force when trying to turn the valves. The high-pressure nature of his position and long working hours are also contributors. Recommended …
Mapping The Socioeconomic Impact Of Hurricane Ian, Jordan Rezende De Lucia
Mapping The Socioeconomic Impact Of Hurricane Ian, Jordan Rezende De Lucia
Student Research Symposium (SRS)
How do natural disasters impact different socioeconomic portions of society, and what spatial patterns emerge in disaster vulnerability, economic recovery, and aid distribution? Natural disasters aren’t felt equally by everyone. This study aims to take a closer look at how pre-existing socioeconomic conditions shape the way different communities are affected and how they recover. I argue that lower-income areas get more adversely affected by natural disasters and recover slower in comparison with wealthier areas. I tested these hypotheses using geospatial data from Hurricane Ian, which hit Florida in September 2022. For the geospatial analysis, I used ArcGIS Pro to map …
Analysis Of Northward Solar Wind High-Energy Plasma Jets In Earth's Magnetosphere, Amelia Koth
Analysis Of Northward Solar Wind High-Energy Plasma Jets In Earth's Magnetosphere, Amelia Koth
Student Research Symposium (SRS)
High-energy plasma jets form when the supersonic solar wind decelerates to subsonic speeds at Earth’s bow shock, producing a turbulent region known as the magnetosheath. Occasionally, the solar wind retains its supersonic nature and penetrates deeper into this region, which generates transient, high-velocity plasma jets directed toward Earth. These jets carry their own magnetic fields, which can interact with Earth’s field, drive magnetic reconnection, and potentially initiate substorms that lead to auroral activity. The NOVA (Northward-Oriented Velocity Analysis of High-Energy Plasma Jets in Earth’s Magnetosphere) study investigates specific jet events that occur during northward interplanetary magnetic field (IMF) conditions. Conducted …

Vibration Control In Uavs For Enhanced Lidar Accuracy Using Metamaterials, Kylie Michaud
Vibration Control In Uavs For Enhanced Lidar Accuracy Using Metamaterials, Kylie Michaud
Student Research Symposium (SRS)
As technology develops, new systems are being created to deliver increased accuracy, cost-effectiveness, and overall efficiency. A specific example of this is LiDAR sensors onboard UAVs for 3D mapping applications of structures. As these sensors become lighter, this allows manufacturing to use smaller UAVs for closer and more confined environmental spaces. However, smaller UAVs introduce higher vibrational frequencies, those that current systems struggle to mitigate. The implementation of metamaterial structures can act as a dampener for these high frequency ranges. Metamaterials can be used to create bandgaps, which can enable frequency ranges that can prevent vibrations from affecting UAVs. Implementation …
