Evolution And Rationale For United States Department Of Defense Electromagnetic Pulse Protection Standard, George H. Baker Iii

Department of Integrated Science and Technology - Faculty Scholarship

The United States (US) Department of Defense (DoD) Electromagnetic Pulse (EMP) protection standard offers a solid basis for protecting commercial communication, data, and control facilities. Because of the standard’s shielded barrier and test requirements, it is not surprising that there is a strong temptation within industry and government to dismiss the MIL-STD 188-125 approach in favor of less rigorous protection methods. It is important to understand that US DoD EMP protection standard for fixed facilities, MIL-STD-188-125, reflects an evolution by trial and error that spanned a period of decades beginning with the acquisition of the Minuteman Missile System in the …

Understanding Identity And Personality Authenticity Of Engineering Students, Kylie D. Stoup

Senior Honors Projects, 2010-2019

Women are underrepresented in engineering, with 18-20% of engineering students being women¹. We, therefore, used the framework of identity theory and self-concept differentiation to better understand female and male engineering student retention. An exploratory approach is used to measure freshman and senior engineering students’ personality and authenticity of personality across engineering and non-engineering contexts. First, we found personality profiles among engineering freshmen and seniors in engineering settings, and then compared them to their personality in nonacademic settings for authenticity purposes. Big 5 Personality and Authenticity scale were methods used through a survey to determine personality and authenticity in …

The Role Of Intrinsic Foot Muscles In Three Running Footwear Conditions, Brian T. Groener

Senior Honors Projects, 2010-2019

Running has grown tremendously in popularity and so has running with minimalist shoes. Injuries such as plantar fasciitis (pain and inflammation of a thick band of tissue that runs across the bottom of the foot) are prevalent in runners despite efforts to design footwear to alleviate the impact of running and to reduce the number of injuries. In the past decade, minimalist running shoes have received considerable attention, causing debate amongst runners and scientists as to their utility in injury prevention. While running barefoot or in minimalist shoes reduces initial impact forces, the claim that they lower injury rates remains …

A Comparison Of Algorithms And Heuristics For Solving The O 1 I N D 1 Shortest Route Problems, Steven D. Young

Senior Honors Projects, 2010-2019

Shortest-path problems have seen a huge amount of study over the course of the last 50 years. Not surprisingly, this means the original problem of finding the shortest path from some starting location to some destination location has been thoroughly studied. However a large number of slight variations on the original problem still have yet to be thoroughly examined. In this paper we examine one of those variations, namely the problem of determining the optimal route from some source location to some destination location such that at least one location in an intermediate set is included in the route. Three …

Madison Engineering is a unique young program that does not follow the traditional teachings of engineering education. The following study analyzes the output variable of academic success of the Madison Engineering program in relation to the culture of the program and the leadership styles of those in management positions within the department. Eight comparative schools were selected, analyzed, and surveyed to compare to Madison Engineering and cross-examine how different leadership styles affect certain outputs.

From extensive research and benchmarking, data was collected to compare measures of leadership and culture to output variables of academic success. A survey was further conducted …

A Concrete Water Pasteurization Device For Third World Countries, Andrea R. Murchie

Senior Honors Projects, 2010-2019

In the rural areas of South Africa, as well as many other developing countries, people cook food and sterilize their water by heating over open fires. Many times the fires are inside of homes, which more often than not are very small. Children will often be the ones to tend to the fire, out of necessity while parents and other family members are tending to other work and needs.

The purpose of my Senior Honors Project was to design a concrete vessel that can hold water and heat the water to pasteurization (149°F) when exposed to sunlight for an extended …

Improving The Security Of Wireless Sensor Networks, Mauricio Tellez Nava

Masters Theses, 2010-2019

With the rapid technological advancements of sensors, Wireless Sensor Networks (WSNs) have become the main technology for the Internet of Things (IoT). We investigated the security of WSNs in an environmental monitoring system with the goal to improve the overall security. We implemented a Secure Temperature Monitoring System (STMS), which served as our investigational environment. Our results revealed a security flaw found in the bootstrap loader (BSL) password used to protect firmware in the MSP430 MCU chips. We demonstrated how the BSL password could be brute forced in a matter of days. Furthermore, we illustrate how an attacker can reverse …

Investigating Security Attacks On Wireless Sensor Networks (Wsns) Via An Iot Environmental Monitoring System, Mauricio Tellez Nava, Samy El-Tawab, M. Hossain Heydari

Showcase of Graduate Student Scholarship and Creative Activities

To demonstrate our work, we have implemented a secure temperature monitoring system that makes use of the IEEE 802.15.4 standard, AES-128 hardware encryption and TelosB sensor nodes. In our design, we consider one of the nodes to be a coordinator node, which plays the role of a central node that establishes network association requests, listens for incoming packets, decrypts the incoming packets and forwards any received packets to the monitoring device. Three other nodes act as end-devices, which play the role of collecting temperature measurements, encrypting the collected data and sending the encrypted packets to the coordinator node. A last …

An Investigation Of Inital Shock Cell Formation In Turbulent Coanda Wall Jets, Caroline P. Lubert, Christian R. Schwantes, Richard J. Shafer

Department of Mathematics and Statistics - Faculty Scholarship

Turbulent Coanda wall jets are present in a multitude of natural and man-made applications. Their obvious advantages in terms of flow deflection are often outweighed by disadvantages related to the increased noise levels associated with these jets. Primary high-frequency noise sources are turbulent mixing noise (TMN) and shock-associated noise (SAN). Clearly, accurate modeling of these noise sources will facilitate better predictions of the behavior of such jet noise with physical characteristics. This paper, which focuses on SAN, shows how the Method of Characteristics can be applied to a steady two-dimensional axisymmetric supersonic flow to rewrite the three governing partial differential …
