Describing the Experiences of Peer Tutors: A Phenomenological Study of Undergraduate Students at Federal Service Academies
Get PDFThe purpose of this transcendental phenomenological study was to describe the experiences of undergraduate students who served as peer tutors (PT) at federal service academies. The following research question provided the framework for this study: How do undergraduate students describe their peer tutoring experiences in federal service academies? Further, I used subquestions in order for participants to fully describe the phenomenon. These included: What were participants’ expectations for being a PT prior to the start of this experience? In what ways were participant expectations met or not met during the peer tutoring experience? What expected and unexpected outcomes were realized by participants during this experience? How do participants describe their short-lived and enduring influences of their peer tutoring experience? Transition theory served as the theoretical framework as it postulates how one transitions during a change in one’s assumptive world. I collected data by seeking voluntary participation through purposeful sampling procedures including both criterion and intensity types. Identified participants recorded information pertinent to their experience through the use of journaling. Participants underwent individual interviews and participated in a focus group in order to describe their experiences. Data were analyzed using the transcendental phenomenological reduction process. Overall, participants described their need to help others, in order to do so, participants described steps they took to ensure they were successful and in doing so, they described the feeling that this role would continue beyond their time at their respective academies. Limitations, implications, and suggestions for further research are also addressed

Jack Voltaic Critical Infrastructure and Public-Private Partnerships
Get PDFThis report summarizes the U.S. Army Cyber Institute’s (ACI’s) work to date on Jack Voltaic (JV), a research project that focuses on critical infrastructure and public-private partnerships (PPPs). JV research, which includes contributions from academia, industry, and government, explores how to synchronize Department of Defense (DoD)/U.S. Government and private sector capabilities in a cyberspace attack response. JV is a research framework that enables the Army to recognize the impacts of cyberspace operations from a municipal and critical infrastructure perspective
Unmanned Aircraft System Swarm for Radiological and Imagery Data Collection
No full textThe purpose of this project is to develop a multi-unmanned aerial system (UAS) to aid in forensic collection and analysis efforts in a post-nuclear blast, by providing a radiation gradient heat map and live video overwatch of the area. An interdisciplinary team of 12 West Point cadets and six faculty advisors took on this challenge as part of a senior level academic capstone project. The team adapted swarm technology available from the DARPA 2016-2017 Service Academy Swarm Challenge. Radiation detectors were integrated onto small quadrotors, and video cameras onto small fixed wing UAS. A sequential greedy task assignment algorithm was implemented to enable distributed control of the swarm. Vehicles divided a survey area, and proceeded to self-assigned locations to take measurements. Gamma radiation dose-rate readings were sent to the ground control station, processed, and fused into a single heat map in real-time. The system was demonstrated at the Idaho National Laboratory in an exercise sponsored by the Defense Threat Reduction Agency. Swarms of up to six vehicles successfully collected data at an active radiation site. In addition, the live video overwatch capability was successfully demonstrated on-site, but stability problems with the fixed wing aircraft prevented the team from fully achieving all surveillance objectives
Jack Voltaic 2.0: Threats to Critical Infrastructure
Get PDFAlthough digital connectivity has made our infrastructure more efficient, it has made it more vulnerable to attack. As a result, infrastructure resilience is more critical today than ever before. Cyberspace attacks rarely affect a single target; instead their effects, anticipated and unanticipated, ripple across interconnected infrastructure sectors. Differing abilities to recognize a cyberspace attack, limited information sharing, varying defense capabilities, and competing authorities complicate the response. These gaps in cybersecurity leave our Nation vulnerable to exploitation by a determined adversary.
The Jack Voltaic 2.0 Cyber Research Project is an innovative, bottom-up approach to developing critical infrastructure resilience. Developed by the Army Cyber Institute at West Point and hosted by the City of Houston, in partnership with AECOM and Circadence, this research assembled critical infrastructure partners to study cybersecurity and protection gaps

Algebraic Curves and Their Applications
No full textThis volume contains a collection of papers on algebraic curves and their applications. While algebraic curves traditionally have provided a path toward modern algebraic geometry, they also provide many applications in number theory, computer security and cryptography, coding theory, differential equations, and more. Papers cover topics such as the rational torsion points of elliptic curves, arithmetic statistics in the moduli space of curves, combinatorial descriptions of semistable hyperelliptic curves over local fields, heights on weighted projective spaces, automorphism groups of curves, hyperelliptic curves, dessins d\u27enfants, applications to Painlevé equations, descent on real algebraic varieties, quadratic residue codes based on hyperelliptic curves, and Abelian varieties and cryptography. This book will be a valuable resource for people interested in algebraic curves and their connections to other branches of mathematics.https://digitalcommons.usmalibrary.org/aci_books/1011/thumbnail.jp

Explosive Welding of Aluminum Plates: Experiments, Evaluation, and Modeling
Get PDFExplosive welding is a field with a wide variety of applications of great value, such as corrosion resistant cladding and bi-metallic joints. It occupies a special place in the available metal joining techniques. Dissimilar metal welding is possible in metal pairings that don’t support other conventional bonds, and it can produce superior area welds regardless of the metal parts to be joined. The objectives of this dissertation were to further the understanding of explosive welding in general, as well as the empirical understanding of welding of Aluminum 6061-O, and to investigate the use of LS-DYNA’s Multi-Material Arbitrary Lagrangian-Eulerian formulation as a potential tool for the design of explosive welds. In the course of the work, the theory on formation of bond interfacial waves was identified as an area where there was not an apparent consensus, and this was addressed in light of both recent works and information from this study. For this dissertation, an experimental program of explosive welding tests, mechanical weld verification, and metallurgical observation were undertaken in order to add to the data available for this type of welding. Nine different explosive welding tests were conducted covering four scenarios, which were combinations of different explosive thicknesses and flyer inclination angles. Tensile shear tests with digital image correlation were used to test the welds, and optical microscope, Scanning Electron Microscope, and Transmission Electron Microscope images were used to investigate the nature of the bond. The numerical investigation was conducted and compared to both experiment and initial modeling results. The results reinforce the need for well-developed and material specific welding windows, adding additional data for the joining of Aluminum 6061-O. The endorsement of the continuous Kelvin-Helmholtz jet wake as the source of instability was supported with modeling results. The Multi-Material Arbitrary Lagrangian Eulerian modeling with Euler-Lagrange Coupling was demonstrated to yield results comparable to research codes for welding parameters, to be able to capture jetting, and provide meaningful temperature results. Bond interfacial waves were characterized with some success as well, concluding that this modeling technique is a viable means to assist in the design of explosive welds
