Introduction To Using Generative Ai In Research Literature Review For Graduate Students, Joseph Vacek
Introduction To Using Generative Ai In Research Literature Review For Graduate Students, Joseph Vacek
AI Assignment Library
Information literacy is a skill set that new graduate students need to learn and practice, and the inclusion of generative AI, including its limitations, is worthy of exploration.

The Lagrange Logistics Method, Jeffrey Rogers
The Lagrange Logistics Method, Jeffrey Rogers
Space Studies Student Publications
Human development into different environments has always required logistics support to sustain life, focusing this research on one method in supporting interplanetary missions beyond Earth. It explores utilizing stations in Lagrange orbital points within the solar system, analogous to transcontinental hubs for logistics operations in an emerging domain. The evaluation considers available Lagrange points, environmental considerations including available resources, flight distances and time in comparison to current interplanetary flight, potential risks, and possibilities beyond the immediate future to determine the practicability of this method. To determine this, a qualitative descriptive analysis method is employed. Data was collected through historical accounts, …
Supplying Space: 3d Printing For Interplanetary Logistics, Jeffrey W. Rogers
Supplying Space: 3d Printing For Interplanetary Logistics, Jeffrey W. Rogers
Space Studies Student Publications
This case study examines 3-D printing as an effective solution to ensure just in time logistics capability for supporting a crewed colony on Mars. It explores the cost to weight benefits of an advanced shipment sent prior to the crewed mission to ensure on-planet production capacity on arrival and landing for sustained operations with limited resupply from Earth. In order to project a realistic and financially reasonable solution, a quantitative descriptive analysis method is utilized. Data was collected through text research and research tools provided from the United States Government (NASA) and private industry via internet sources. From correlated data, …
A Test-Bed For Measuring Uas Servo Reliability, Abdelrahman Elsaid, Daniel Kwasi Adjekum, John Nordlie, Fatima El Jamiy
A Test-Bed For Measuring Uas Servo Reliability, Abdelrahman Elsaid, Daniel Kwasi Adjekum, John Nordlie, Fatima El Jamiy
Aviation Faculty Publications
Extant literature suggests minimal research on the reliability of Commercial off-the-shelf (COTS) components used in fabricating non-military Unmanned Aerial System (UAS). Stochastic failures of components during operational cycles over time poses a safety hazard to flight operations. The purpose of the study was to critically assess the operational performance standards (reliability) of a laboratory designed UAS component test-bed operated using real-world data collected from a Boeing Scan Eagle® UAS aileron servo unit via a flight data recorder. The study hypothesized that the test-bed’s reliability, in terms of a measured encoder output of commanded servo positions, will not be significantly …
Compensating For Cryogenic Propellant Boiloff For A Cargo Mission To Mars, Thomas M. Perrin, James Casler
Compensating For Cryogenic Propellant Boiloff For A Cargo Mission To Mars, Thomas M. Perrin, James Casler
Space Studies Faculty Publications
A previous work by the authors (Architecture Study for a Fuel Depot Supplied from Lunar Resources – AIAA 2016-5306) examined architectures for a fuel depot supplied from lunar ice deposits. The study recommended a fuel depot be located at Earth-Moon L1. The study used three design reference missions in the formulation of candidate architectures – among them a Mars Cargo Vehicle (MCV). Each vehicle used 60 layers of multi-layer insulation (MLI) to minimize the boiloff of cryogenic propellants. Boiloff was shown to not be a driver in architecture selection, but it was noted that reducing the number of layers of …
An Evaluation Of The Relationships Between Collegiate Aviation Safety Management System Initiative, Self-Efficacy, Transformational Safety Leadership And Safety Behavior Mediated By Safety Motivation, Daniel Kwasi Adjekum
Aviation Faculty Publications
The study conceptualized Safety Management System (SMS) initiative, self-efficacy, and transformational safety leadership as constructs that relates to safety behavior (measured by safety compliance and safety participation) when mediated by safety motivation using a quantitative approach. Structural equation modeling techniques was used to derive a final measurement model that fit the empirical data and was used to test the study hypotheses. Utilizing a sample of 282 collegiate flight students and instructors from a large public university in the US, a 46-item survey was used to measure respondent’s perceptions on the study variables. The results indicate that perceptions of SMS policy …
Bio-Fuel Alternatives In South African Airways (Saa) Operations - Is It An Effective Response To Vulnerability Over Carbon Taxes And Penalty?, Daniel Kwasi Adjekum
Bio-Fuel Alternatives In South African Airways (Saa) Operations - Is It An Effective Response To Vulnerability Over Carbon Taxes And Penalty?, Daniel Kwasi Adjekum
Aviation Faculty Publications
The paper did a comparative analysis of the carbon emission and European Union Emission Trading Surcharges (EU ETS) of South African Airways (SAA) current fleet that used aviation jet A1 fuel and the same fleet if it had used a 25% bio-fuel ‘drop in’ for the European routes within the first quarter of the 2014 flying year (FY 14). Operational data in terms of the flight scheduled, aircraft type, total time enroute, route stage length, passenger estimates were obtained through SAA’s flight operations website. An independent t–test was conducted to compare means of the emissions. The mean carbon dioxide …
