Improvements To Isru For Rocket Fuel Generation, Justin Sharp
Improvements To Isru For Rocket Fuel Generation, Justin Sharp
James Madison Undergraduate Research Journal (JMURJ)
The development of efficient in-situ resource utilization (ISRU) technologies is crucial for the establishment of an extraterrestrial, self-sustaining colony. The generation of rocket fuel at potential colony locations is necessary to provide the transportation of people and cargo to and from these locations.Three processes are discussed for the improvement of ISRU methods to generate rocket fuel: electrolysis and electrochemical improvements to the process of crude fuel production, physical and chemical methods for separation of gaseous H2 and O2, and materials and cryogenics engineering for storage and transportation of liquid hydrogen (LH2) and liquid oxygen (LOX). Storage and transportation of cryogenics …
Dynamic Return Relationships In The Market For Cryptocurrency: A Var Approach, Julian Gouffray
Dynamic Return Relationships In The Market For Cryptocurrency: A Var Approach, Julian Gouffray
James Madison Undergraduate Research Journal (JMURJ)
This paper examines how the Bitcoin-altcoin return relationship has evolved in periods between 2015 and 2020. To understand this relation, we observe data on the cryptocurrency Bitcoin and prominent altcoins Ethereum, Litecoin, Ripple, Stellar, and Monero, which collectively represent over 90% of the market throughout the observed period. We employ a vector autoregressive model (VAR) to produce forecast error variance decompositions, orthogonal impulse response functions, and Granger-causality tests. We find evidence that Bitcoin return variation has increasingly explained altcoin returns and that market inefficiency increased between 2017 and 2020, as shown by increased Granger causality between Bitcoin and altcoins. These …
Deep Fakes: The Algorithms That Create And Detect Them And The National Security Risks They Pose, Nick Dunard
Deep Fakes: The Algorithms That Create And Detect Them And The National Security Risks They Pose, Nick Dunard
James Madison Undergraduate Research Journal (JMURJ)
The dissemination of deep fakes for nefarious purposes poses significant national security risks to the United States, requiring an urgent development of technologies to detect their use and strategies to mitigate their effects. Deep fakes are images and videos created by or with the assistance of AI algorithms in which a person’s likeness, actions, or words have been replaced by someone else’s to deceive an audience. Often created with the help of generative adversarial networks, deep fakes can be used to blackmail, harass, exploit, and intimidate individuals and businesses; in large-scale disinformation campaigns, they can incite political tensions around the …
An Analysis Of Technological Components In Relation To Privacy In A Smart City, Kayla Rutherford, Ben Lands, A. J. Stiles
An Analysis Of Technological Components In Relation To Privacy In A Smart City, Kayla Rutherford, Ben Lands, A. J. Stiles
James Madison Undergraduate Research Journal (JMURJ)
A smart city is an interconnection of technological components that store, process, and wirelessly transmit information to enhance the efficiency of applications and the individuals who use those applications. Over the course of the 21st century, it is expected that an overwhelming majority of the world’s population will live in urban areas and that the number of wireless devices will increase. The resulting increase in wireless data transmission means that the privacy of data will be increasingly at risk. This paper uses a holistic problem-solving approach to evaluate the security challenges posed by the technological components that make up a …
Using Residential Location To Assess The Environmental Value-Action Gap Of Students At James Madison University, Emma Martin
Using Residential Location To Assess The Environmental Value-Action Gap Of Students At James Madison University, Emma Martin
James Madison Undergraduate Research Journal (JMURJ)
This study focuses on the environmental value-action gap of students at James Madison University (JMU) in Harrisonburg, Virginia. An environmental value-action gap occurs when a person has pro-environmental beliefs but does not have congruent actions. Over 1,000 JMU students completed a survey of their residence location, environmental values, and environmental actions. Students’ preservation and utilization values were assessed using a 2-Dimensional Model of Ecological Values (2-MEV), and their frequency of environmental actions was assessed through a series of Likert-scaled statements. It was hypothesized that any value-action gap would be wider in students who resided in off-campus housing compared to students …

Narrowing The Digital Divide: The Young Women Leaders Program Herstory Project, Stephanie Newton, Emily Peters, Victoria Tucker, Christine Quilpa, Edith Lawrence, Clare Vierbuchen
VA Engage Journal
Research suggests that girls are at especial disadvantage in the field of informational technology and are less likely than boys to take courses or seek out careers in this area. The Young Women Leaders Program (YWLP), a mentoring program at the University of Virginia that pairs at-risk middle school girls with college women for a year of mentoring, developed the YWLP HerStory project to engage middle school girls in informational technology through their development of technology projects focused on psychosocial issues of importance to them. This study reviewed an early version of the YWLP HerStory’s technology curriculum and training for …
Smoke Signals: An Investigation Of The Effects Of Eco-Stoves On Community And The Environment, Claire Hennigan, Amy Rogers
Smoke Signals: An Investigation Of The Effects Of Eco-Stoves On Community And The Environment, Claire Hennigan, Amy Rogers
VA Engage Journal
The use of solid biomass fuels and the implementation of eco-stoves to mitigate its harmful effects has become a popular topic in discussions on global development. An article published on use of traditional fuels in The New Yorker reports, “A map of the world's poor is easy to make…just follow the smoke.” Eco-stoves are now being constructed in impoverished communities around the world as an alternative to traditional stove models as a means to improve health and overall quality of life. Global Brigades, a sustainable development NGO, has been working in communities in rural Honduras to construct an eco-stove model …
