Theses and Dissertations

The United States Air Force is in a state of transformation. Due to ongoing operations in Iraq and Afghanistan, the focus of Basic Military Training is shifting to basic combat skills, or the skills needed to survive and operate in a hostile environment. In this study, basic combat skills training was evaluated using a number of training factors that potentially affect trainees’ perception of training transfer, or their ability to apply the skills they learned in training on the job or in a hostile environment. The analysis used structural equation modeling to evaluate the paths between each of the factors …

Analyzing The Interdiction Of Sea-Borne Threats Using Simulation Optimization, Kristen L. Cavallaro

Theses and Dissertations

Worldwide, maritime trade accounts for approximately 80% of all trade by volume and is expected to double in the next twenty years. Prior to September 11, 2001, Ports, Waterways and Coastal Security (PWCS) was afforded only 1 percent of United States Coast Guard (USCG) resources. Today, it accounts for nearly 22 percent of dedicated USCG resources. Tactical assessment of resource requirements and operational limitations on the PWCS mission is necessary for more effective management of USCG assets to meet the broader range of competing missions. This research effort involves the development and validation of a discrete-event simulation model of the …

Dynamic Response Of A Collidant Impacting A Low Pressure Airbag, Peter A. Dreher

Theses and Dissertations

There are many uses of low pressure airbags, both military and commercial. Many of these applications have been hampered by inadequate and inaccurate modeling tools. This dissertation contains the derivation of a four degree-of-freedom system of differential equations from physical laws of mass and energy conservation, force equilibrium, and the Ideal Gas Law. Kinematic equations were derived to model a cylindrical airbag as a single control volume impacted by a parallelepiped collidant. An efficient numerical procedure was devised to solve the simplified system of equations in a manner amenable to discovering design trends. The largest public airbag experiment, both in …

Approximate Analysis Of An Unreliable M/M/2 Retrial Queue, Brian P. Crawford

Theses and Dissertations

This thesis considers the performance evaluation of an M/M/2 retrial queue for which both servers are subject to active and idle breakdowns. Customers may abandon service requests if they are blocked from service upon arrival, or if their service is interrupted by a server failure. Customers choosing to remain in the system enter a retrial orbit for a random amount of time before attempting to re-access an available server. We assume that each server has its own dedicated repair person, and repairs begin immediately following a failure. Interfailure times, repair times and times between retrials are exponentially distributed, and all …

Patterns Of War Termination: A Statistical Approach, Paul D. Robinson Ii

Theses and Dissertations

This research uses an advanced statistical technique to expand upon the current understanding of war termination. Specifically, this thesis addressed questions concerning the most relevant factors toward predicting both the outcomes of interstate wars and the winners of intrastate and extra-systemic wars, within the limitations of the available data. Open-source war data from the Correlates of War Project was analyzed using both binary and multinomial logistic regression techniques. While the Correlates of War Project did not necessarily focus its data collection efforts on those variables historically associated with war termination, it did provide a sufficient number of variables with which …

Mathematical Programming Model For Fighter Training Squadron Pilot Scheduling, Thomas M. Newlon

Theses and Dissertations

The United States Air Force fighter training squadrons build weekly schedules using a long and tedious process. Very little of this process is automated and optimality of any kind is nearly impossible. Schedules are built to a feasible condition only to be changed with consideration of Wing level requirements. Weekly flying schedules are restricted by requirements for crew rest, days since a pilot's last sortie, sorties in the last 30 days, and sorties in the last 90 days. By providing a scheduling model to the pilot charged with creating the schedule, valuable pilot hours could be spent in the cockpit, …

Classifying Failing States, Nathan E. Nysether

Theses and Dissertations

The US is heavily involved in the first major war of the 21st Century -- The Global War on Terror (GWOT). As with any militant group, the foundation of the enemy's force is their people. There are two primary strategies for defeating the terrorists and achieving victory in the GWOT. First, we must root out terrorists where they live, train, plan, and recruit and attack them militarily. Second, we must suffocate them by cutting off the supply of new soldiers willing to choose aggression or even death over their current life. This thesis helps to achieve these objectives by applying …

A Future-Based Risk Assessment For The Survivability Of Long Range Strike Systems, William D. Heuck Jr.

Theses and Dissertations

The United States Air Force today faces the challenge of allocating development resources to prepare for future force projection requirements. In particular, the Air Force's core competency of Global Attack implies a future capability that can quickly and successfully deliver combat effects anywhere in the world with impunity. Understanding that the future threat environment is dynamic and that continued advancements by adversaries will likely degrade the technical superiority of today's weapon systems, the need arises for a planning model to direct development funding to areas with the greatest probability of successfully defending the strike vehicle of 2035. Examining this problem …

Passive Geolocation Of Low Power Emitters In Urban Environments Using Tdoa, Myrna B. Montminy

Theses and Dissertations

Low-power devices are commonly used by the enemy to control Improvised Explosive Devices (IEDs), and as communications nodes for command and control. Quickly locating the source of these signals is difficult, especially in an urban environment where buildings and towers can cause interference. This research presents a geolocation system that combines several geolocation and error mitigation methods to locate an emitter in an urban environment. The proposed geolocation system uses a Time Difference of Arrival (TDOA) technique to estimate the location of the emitter of interest. Using sensors at known locations, TDOA estimates are obtained by cross-correlating the signal received …

The Influence Of The First World War On The Church Of Jesus Christ Of Latter-Day Saints, James I. Mangum

Theses and Dissertations

The Church of Jesus Christ of Latter-day Saints and its membership felt a substantial impact from the effects of World War I. Although other authors have attempted to bring forward the events of these hostilities, they are few in number and the research in this area is small. Additionally, few have focused on the effects of the war on the Church. In order to increase the understanding of this influence, this work examines how the First World War affected the lives of Latter-day Saints both during and after the conflict. The entire world felt the effects of the world war …

Role Of Trauma In Social-Cognitive Adjustment Strategies And Moral Disengagement Among African-American Urban Youth, Kendell Lamonte Coker

Theses and Dissertations

The role of trauma has been implicated in the etiology of juvenile delinquency (Esbensen & Huizinga, 1991; Dulmus, 2003). This is especially pronounced among inner city minority youth. Traumatic experiences can hinder an adolescent's social-cognitive development, prevent the use of adequate coping mechanisms and cognitive processes, such as social problem solving, and lead youth to disengage their moral controls (Ng-Mak, Salzinger, Feldman, & Stueve, 2002). The purpose of this study was to explore the effects of trauma and adjustment strategies among African American urban youth and how moral disengagement can be averted via mediation by the use of social problem …

The Rhetoric Of Picasso, Matthew R. Sharp

Theses and Dissertations

Pablo Picasso was arguably the most famous and controversial artist of the twentieth century, and some of his most famous pieces were created during the Spanish Civil War (1936-1939) in response to the horrible atrocities taking place in his homeland. "The Rhetoric of Picasso" by Matthew R. Sharp, filed December 2007, examines some of these works—including paintings such as Guernica and Weeping Woman —and theorizes their rhetorical force, using speech act theory as the theoretical lens. Based on common images and themes in Picasso's symbolism, it is determined that Picasso's works during the Spanish Civil War are expressive speech acts …

Lets Make It Outback Tonight, Michael Douglas Erickson

Theses and Dissertations

When I was younger, shortly after my father died, my mother bought me a t-shirt that I loved and wore till it was worn out. On the shirt there was an image of a man, strapped into an electric chair, holding pieces of bread in each hand. A sign above him read, "Making the best of a bad situation." That statement became a mantra I held onto in the early years after my father's death. It still guides my personal philosophy---humor is key to survival. Particularly a type of humor that celebrates the fact that "shit happens", while highlighting and …

Life In An Occupied City: Women In Winchester, Virginia During The Civil War, Laura Jane Ping

Theses and Dissertations

This thesis examines the homefront experience of middle class, white women living in Winchester, Virginia during the Civil War. The experience of women in Winchester was unique because of Winchester's proximity to both the Union and Confederate capitals. Although the majority of Winchester's women were Confederate supporters a significant minority of the population remained loyal to the Union. Winchester citizens' divided status was further complicated by numerous occupations of the town by both armies. This thesis argues that in order to cope with wartime hardships women's concepts of patriotism changed as homefront morale waned. While early in the war women's …

Disaster Communication Networks: A Case Study Of The Thai Red Cross And Their Disaster Communication Response To The Asian Tsunami, Tami J. Matthews

Theses and Dissertations

Disaster victims and vulnerable populations are audiences that communications professionals and scholars have ignored. Public relation practices dominate current disaster communication policy. This study examines the disaster communication network, including policy and practice, of the Thai Red Cross, before, during, and after the Asian tsunami. Disaster communication(s) is defined as the sharing and exchange of information with the victims immediately affected by a disaster. This definition focuses specifically on the vulnerable audience and allows response efforts to emerge from multiple disciplines. Focusing response efforts on victims' assessed needs and abilities allows for a multi-disciplinary approach to mitigate further suffering. The …

Pilgrimage Narrative: A Pattern For Heavenly Theatre In King Lear, Alexandra Chantal Yvette Mackenzie

Theses and Dissertations

I have always felt personally challenged and invigorated by one line in Peter Brook's canonical text The Empty Stage: “if the need for a true contact with a sacred invisibility through the theatre still exists, then all possible vehicles must be re-examined" (Brook 54). This thesis will endeavour to suggest and explore heavenly theatre, one possible vehicle to find that sacred invisibility. I will argue that heavenly theatre encompasses Peter Brook's understanding of holy theatre, but is more specific and tied to the manifestation of deity in the form of the Holy Spirit as understood and defined within my personal …

Integrated Conceptual Design Of Joined-Wing Sensor Craft Using Response Surface Models, Josh E. Dittmar

Theses and Dissertations

A multidisciplinary conceptual design and analysis of Boeing's joined-wing SensorCraft has been conducted. This analysis was completed using geometrical optimization, aerodynamic analyses, and response surface methodology on a composite structural model.

By seeking to miniaturize and automate separation-based analysis, microfluidic research seeks to improve current methods through decreased cost, analysis time, and sources of contamination. My work has focused on developing a novel fabrication method, based on standard microfabrication techniques, to create thin-film microfluidic devices. This microfabrication format makes it possible to generate devices that provide high efficiencies, enable mass fabrication, and provide a platform capable of integrating the microfluidic and electronic components necessary for a micro-total analysis system (μ-TAS). Device fabrication combines the processes of …

Analysis Of Layered Social Networks, Jonathan T. Hamill

Theses and Dissertations

Prevention of near-term terrorist attacks requires an understanding of current terrorist organizations to include their composition, the actors involved, and how they operate to achieve their objectives. To aid this understanding, operations research, sociological, and behavioral theory relevant to the study of social networks are applied, thereby providing theoretical foundations for new methodologies to analyze non-cooperative organizations, defined as those trying to hide their structure or are unwilling to provide information regarding their operations. Techniques applying information regarding multiple dimensions of interpersonal relationships, inferring from them the strengths of interpersonal ties, are explored. A layered network construct is offered that …

A General Framework For Analyzing, Characterizing, And Implementing Spectrally Modulated, Spectrally Encoded Signals, Marcus L. Roberts

Theses and Dissertations

Fourth generation (4G) communications will support many capabilities while providing universal, high speed access. One potential enabler for these capabilities is software defined radio (SDR). When controlled by cognitive radio (CR) principles, the required waveform diversity is achieved via a synergistic union called CR-based SDR. Research is rapidly progressing in SDR hardware and software venues, but current CR-based SDR research lacks the theoretical foundation and analytic framework to permit efficient implementation. This limitation is addressed here by introducing a general framework for analyzing, characterizing, and implementing spectrally modulated, spectrally encoded (SMSE) signals within CR-based SDR architectures. Given orthogonal frequency division …

As the Department of Defense continues its transformations to a network centric force, evaluating DoD's progression towards net-centricity remains a challenge. This research proposes to extend the Network Centric Operation Common Framework Version 2.0 (draft) with the metrics based in graph theory and, specifically addresses, among other metrics, the measurement of a net-centric force's mission effectiveness. The research incorporates the importance of understanding network topology for evaluating an environment for net-centricity and using network characteristics to help commanders assess the effects of network changes on mission effectiveness. The multi-layered model of Network Centric Operations and interlayer mapping are introduced to …

Three Component Velocity Measurements In The Tip Vortex Of A Micro-Air-Vehicle, Hong-Joon Park

Theses and Dissertations

The purpose of this research was to improve the MAV that will be used for battle damage assessment and reconnaissance or local surveillance through the experiments in AFIT wind tunnel. The experiments were performed to investigate the wing displacement and wing tip vortex interaction. To conduct the experiments, telescopic survey tool and tri-axial hot-wire anemometer was utilized. The results indicate that wing tip displacement of the flexible wing was approximately 8 times that of the rigid wing in an unstalled condition and data suggests that flexible wing has a denser core-distribution of velocity within the wing tip vortex and delays …

Enhanced Electrospray Ionization For Mass Spectrometry And Ion Mobility Spectrometry, Li Zhou

Theses and Dissertations

Electrospray ionization (ESI) has become one of the most commonly used ionization techniques for mass spectrometry (MS) and ion mobility spectrometry (IMS), and efforts continue to improve its performance. ESI-MS is most recognized for its wide application to biomacromolecules where high sensitivity is of paramount importance. However, the major limitation in sensitivity with ESI-MS is due to its low ion transmission efficiency from the ESI source into the sampling orifice and through any stages utilized for transfer of ions from atmosphere to vacuum in the MS. A series of atmospheric pressure ion focusing interfaces were designed and implemented to enhance …

Theoretical Modeling Of The Transient Effects Of A Towline Using The Method Of Characteristics, Christopher A. Hill

Theses and Dissertations

The use of decoys in combat has become more advanced in recent years. Some of the newest military aircraft, such as the US Navy's F/A-18E/F Superhornet, have the capability to deploy a towline with an attached decoy when entering hostile territory as a defense mechanism against enemy threats. In steady state, the towline extends behind and below the aircraft. A major concern is the position of the towline, as aircraft maneuvers can cause the line to enter the engine plume. The high exhaust heat can cause problems, such as damaging electrical equipment and severing the line. In order to better …

Characterization Of Uav Performance And Development Of A Formation Flight Controller For Multiple Small Uavs, Patrick A. Mccarthy

Theses and Dissertations

The Air Force Institute of Technology's (AFIT) Advanced Navigation Technology (ANT) Center has recently delved into the research topic of small Unmanned Aerial Vehicles (UAV). One area of particular interest is using multiple small UAVs cooperatively to improve mission efficiency, as well as perform missions that couldn't be performed using vehicles independently. However, many of these missions require that the UAVs operate in close proximity of each other. This research lays the foundation required to use the ANT Center's UAVs for multi-vehicle missions (e.g. cooperatively) by accomplishing two major goals. First, it develops test procedures that can be used to …
