The Off Season: Masculinities, Rurality, And Family Ties In Alaska Commercial Fishing, Cruz Morey
The Off Season: Masculinities, Rurality, And Family Ties In Alaska Commercial Fishing, Cruz Morey
Senior Theses
This study explores the intersections of masculinity, rurality, the family, and ecology through the experiences of commercial fishermen in Alaska. By understanding the plurality of masculinities and how men operate within a rural space, this study investigates the relationship between the masculine rural and the rural masculine and how that relationship pertains to commercial fishermen. This study examines existing discourse about Alaska and the masculinity of commercial fishermen in light of the concepts of cultural and economic capital, as well as local ecological knowledge (LEK). It further examines how fishermen describe their experiences in the industry as ones that are …
Operating Temperature Of A Solar Thermal Stirling Engine, Spencer Beck
Operating Temperature Of A Solar Thermal Stirling Engine, Spencer Beck
Senior Theses
This paper explores the relationship between the operating temperature and electricity production of a simple heat engine. A Stirling engine was designed and constructed which runs on solar thermal energy collected by a Fresnel lens. The surface area of the solar collector was varied. This manipulated the operating temperature of the Stirling engine in order to measure power output. The mechanical energy from the engine was converted to electricity using a DC motor running in reverse, acting like a generator, in conjunction with an Arduino for data collection. Although adjustments must be made in order to improve the efficiency of …
Thin Film Thermal Deposition At Various Pressures, James Kela Yee Keen Grace
Thin Film Thermal Deposition At Various Pressures, James Kela Yee Keen Grace
Senior Theses
This research was to verify the hypothesis that resistivity of metal's thin film deposited in a low-pressure environment is the same as its solid material. Thermal Evaporation is a thin film deposition technique in which metal inside a vacuum is evaporated, then deposited onto a surface. Higher quality metal films are deposited when the vacuum pressure is lower. At higher pressures, more air molecules are trapped within the layers of metal, thus increasing scattering sites and increasing the resistance. However, reaching a lower pressure requires more time and effort. In this research, films were deposited at various pressures and resistivities …
Are Solar Panels A Viable Power Source For A Green Energy Vehicle?, Mason C. Adams
Are Solar Panels A Viable Power Source For A Green Energy Vehicle?, Mason C. Adams
Senior Theses
A solar cell powered go-kart has been built and tested. The result shows using solar energy alone cannot meet the requirement of running a regular passenger car. This is due to the limited surface area of the passenger car. This thesis also discusses the operating principles of solar panels, the physics of P type and N type semiconductors, and the formation of the PN junction, as well as the solar current. Modifications of an existing go-kart are described in detail in this thesis. Suggestions for making green vehicles are discussed as well.
Observing Orbital Angular Momentum Transfer From Electron Vortex Beams To Matter, Hannah Devyldere
Observing Orbital Angular Momentum Transfer From Electron Vortex Beams To Matter, Hannah Devyldere
Senior Theses
It is possible to produce electron beams with non-zero orbital angular momentum. Such beams, known as electron vortex beams, are theoretically able to transfer their orbital angular momenta to matter, causing the matter to rotate. Nanoparticles in an aqueous solution were observed with an electron vortex beam to detect the transfer of orbital angular momentum in a low-friction environment. Observing the transfer of orbital angular momentum to particles in solution is difficult due to the necessity of imaging the particles through a liquid and the random movement of particles in the solution. Thus, orbital angular momentum transfer to matter could …
Building And Validating A Model For Investigating The Dynamics Of Isolated Water Molecules, Grant Cates
Building And Validating A Model For Investigating The Dynamics Of Isolated Water Molecules, Grant Cates
Senior Theses
Understanding how water molecules behave in isolation is vital to understand many fundamental processes in nature. To that end, scientists have begun studying crystals in which single water molecules become trapped in regularly occurring cavities in the crystal structure. As part of that investigation, numerical models used to investigate the dynamics of isolated water molecules are sought to help bolster our fundamental understanding of how these systems behave. To that end, the efficacy of three computational methods—the Euler Method, the Euler-Aspel Method and the Beeman Method—is compared using a newly defined parameter, called the predictive stability coefficient ρ. This …
A Perspective On How To Improve Undergraduate Research Education In The Physical Sciences At Usc, Michael Caleb Bagley
A Perspective On How To Improve Undergraduate Research Education In The Physical Sciences At Usc, Michael Caleb Bagley
Senior Theses
My years at the University of South Carolina have been some of the most challenging and edifying periods of my life. I have been blessed by having a great professional and chemistry mentor in Dr. John L. Ferry who has helped me engage in scientific research in a meaningful way. As I watched other chemistry students, in particular, struggle with understanding what research really was and even how to understand the results and methodologies of it I felt that this was a huge issue that could be rather simply fixed. I have been privileged to apply for and receive a …
A Study Of Anti-Muon-Neutrino Induced Resonance Production In Nomad Three-Track Topology, Edward Dunton
A Study Of Anti-Muon-Neutrino Induced Resonance Production In Nomad Three-Track Topology, Edward Dunton
Senior Theses
In this study we are attempting to measure the sensitivity of our methods to anti-muon neutrino induced resonance interactions in the 3-track topology of the NOMAD experiment. We will use a set of Monte Carlo data meant to resemble the NOMAD outputs but with true event type known and then proceed by using a system of single-variable cuts and multivariable analysis through a multilayer perception neural network to distinguish events from these interactions and events from other neutrino or non-neutrino interactions. We will then produce a measurement of the sensitivity to these interactions and determine whether or not proceeding with …
Google Street View As A Medium For Social Gaming, Steven Dao, Tien Ho, Austin Pahl
Google Street View As A Medium For Social Gaming, Steven Dao, Tien Ho, Austin Pahl
Senior Theses
safehouse is a head-to-head Street View game drawing inspiration from GeoGuessr and Pursued. It will be available to play in a web browser on our website, http://thesafe.house. The game aims to let players discover new places in the world in a uniquely competitive way. At the start of each match, players will find themselves in a random Street View location in an unknown area, pitted against each other with one of two tasks: the pursued must locate a safe house somewhere in the city, and the pursuer must catch the pursued. Each player will have to rely on quick …
Addressing The Issue Of Climate Change Denial, Katherine M. Kacsur
Addressing The Issue Of Climate Change Denial, Katherine M. Kacsur
Senior Theses
Climate change is real. It is not a debate, and it is not a theory. It is not a part of the “liberal agenda”, and is not a ploy to raise taxes or expand government. Climate change is real, and it is happening right now. Every time someone starts their car, turns on a light, or cranks up the air conditioning, carbon dioxide is added to the atmosphere. Because of its power to capture heat in the atmosphere, carbon dioxide has allowed for more and more warming around the globe. As energy consumption only continues to increase, the effects of …
The Nano-Adventures Of Gold And Silver: An Ios Game, Elizabeth Pruett
The Nano-Adventures Of Gold And Silver: An Ios Game, Elizabeth Pruett
Senior Theses
The Nano-Adventures of Gold and Silver is an iOS game intended for young students to learn about nanoscience and the benefits and harms of various nanoparticles in the environment, originally created by the Center for Environmental Nanoscience and Risk. This project exists as the first iteration of a game about two superheroes, Nano-Gold and Nano-Silver, who invite players along as they use their powers to deal with different scenarios. Over the course of a year, the game was designed, developed, and tested; the resulting application includes user authentication capabilities, an origin story detailing the Nano-Girls narrative, and a complete level, …
