Using Discovery-Based Learning To Prove The Behavior Of An Autonomous Agent, David N. Mezera
Using Discovery-Based Learning To Prove The Behavior Of An Autonomous Agent, David N. Mezera
Theses and Dissertations
Computer-generated autonomous agents in simulation often behave predictably and unrealistically. These characteristics make them easy to spot and exploit by human participants in the simulation, when we would prefer the behavior of the agent to be indistinguishable from human behavior. An improvement in behavior might be possible by enlarging the library of responses, giving the agent a richer assortment of tactics to employ during a combat scenario. Machine learning offers an exciting alternative to constructing additional responses by hand by instead allowing the system to improve its own performance with experience. This thesis presents NOSTRUM, a discovery-based learning DBL system …

An Analysis Of Fm Jamming And Noise Quality Measures, Timothy N. Taylor
An Analysis Of Fm Jamming And Noise Quality Measures, Timothy N. Taylor
Theses and Dissertations
This thesis provides a description of FM-by-noise jamming, both at RF and at the output of the radar receiver, in terms of spectra, time-domain waveforms, and univariate probability density of amplitude. Particular emphasis is given to the case where the peak frequency deviation of the FM modulator is sufficiently small that Woodward's Theorem does not provide a good approximation of the RF spectrum. Additionally, noise quality measures which have been used to measure noise quality of radar jammers are considered theoretically and experimentally, and it is concluded that a noise measure which incorporates both a spectral measure and a probability …
Research And Development Project Selection Tools: Probing Wright Laboratory's Project Selection Methods And Decision Criteria Using The Lateral Airfoil Concept, James E. Barger
Theses and Dissertations
This research accomplished three major tasks. First it examined familiarity and usage rates for fifteen published R&D project selection methods in the context of a larger general issue, the Air Force's ability to develop and exploit technology. Wright Laboratory served as the focus for the research effort and displayed a greater tendency to use formal methods in 1993 than was shown in prior research. The laboratory's overall preference for simpler models like Checklist, Scoring, and Sorting led to a recommendation that authors familiar with the other techniques communicate them in engineering and management vernacular. Secondly, the study introduced a technological …
A Study Of Air Force Theater-Based Contingency Contracting Training Requirements For A Power Projection Strategy, Jon B. Tigges, Thomas J. Snyder
A Study Of Air Force Theater-Based Contingency Contracting Training Requirements For A Power Projection Strategy, Jon B. Tigges, Thomas J. Snyder
Theses and Dissertations
This research examined the training needs for contingency contracting officers for a Power Projection Strategy. Contingency contracting officers (CCOs) that deployed to Operation Desert Shield/Storm (ODS) where asked to provide their perceptions of the training they received before ODS, training and equipment needs identified as a result of lessons learned from ODS, and whether current training meets those needs. The results of the study show that CCOs believe there are many areas of training that can be improved to ensure future contingency participants do not have to relearn the same lessons of ODS.

The Use Of Simulation To Evaluate Strategic Aeromedical Evacuation Policy And Planning, Charles W. Wolfe Jr.
The Use Of Simulation To Evaluate Strategic Aeromedical Evacuation Policy And Planning, Charles W. Wolfe Jr.
Theses and Dissertations
Strategic aeromedical evacuation (AE) of casualties from the theater of operations to the CONUS during wartime is a complex operation that involves the integration of medical personnel and policies with airlift concepts and capabilities. Military analysts within the Air Mobility Command Analysis Group (AMC/XPY) have traditionally used deterministic linear programming techniques to estimate the number of aircraft the United States Air Force (USAF) requires for given contingency scenarios. However, this group has yet to develop a stochastic approach to validate their resource recommendations, and more importantly, to study the interrelationships between key factors comprising strategic aeromedical evacuation. As the possibility …

Integrating Psychological Operations Into The Joint Theater Level Simulation (Jtls), C. Matthew Pecot Iii
Integrating Psychological Operations Into The Joint Theater Level Simulation (Jtls), C. Matthew Pecot Iii
Theses and Dissertations
This thesis provides a prototype and methodology for integrating psychological operations (PSYOP) into the Joint Theater Level Simulation (JTLS) combat model. The requirement rose out of the need for aggregate-level training models to reflect the role of PSYOP so that commanders and their staffs can learn how to manage plan for, and conduct PSYOP within the context of AirLand battle doctrine. As the JTLS model currently exists, there is no representation of psychological operations whatsoever. This thesis outlines a methodology for incorporating the PSYOP analysis process (including the target audience analysis), the PSYOP product development and production process, the PSYOP …

An Analysis Of The Ability Of Commercial Wargames To Fulfill The Education Requirements Of The Air Force Wargaming Center, Scott Goehring
Theses and Dissertations
It has been the contention of some that current commercial wargames could possibly fulfill the education requirements addressed by the Air Force Wargaming Center. The Wargaming Center, lacking the opportunity to conduct a thorough, in-house analysis of these commercial wargames, requested an independent evaluation be performed. This thesis identifies potential commercial wargames and provides an analysis of those wargames to determine their ability to educate senior military officers in the application of aerospace power. In addition, this thesis establishes a set of Measures of Effectiveness (MOEs) against which future wargames can be easily evaluated. The MOEs were developed from the …
The Battle Of Little Round Top: An Analysis Of Battle Alternatives Through Commercial Wargames, John J. Mcguiness
The Battle Of Little Round Top: An Analysis Of Battle Alternatives Through Commercial Wargames, John J. Mcguiness
Theses and Dissertations
This thesis examines the problem of whether one can use commercial wargames as a tool for historical research. The research examines two wargames dealing with the battle of Little Round Top: Gettysburg: The Turning Point and Thunder at the Crossroads. This research emphasized the need to analyze the wargame's structure prior to playing the game. This will avoid a possible mistake of drawing a conclusion about a particular driver in the battle which may not be from the historical situation but rather an inevitable outcome produced by the model's basic assumptions. Additionally, quantitative measures of time lines, casualty rates, and …

An Analytical And Experimental Investigation Of Fm-By-Noise Jamming, Charles J. Daly
An Analytical And Experimental Investigation Of Fm-By-Noise Jamming, Charles J. Daly
Theses and Dissertations
Among the jamming waveforms used in Electronic Warfare, FM-by-noise is the least understood, and no exhaustive analytical and experimental investigation of the subject exists. This investigation presents a thorough review, consolidation, and elucidation of the theory of FM-by-noise. To explain and predict the behavior of FM-by-noise at RF and IF, three useful ratios, namely the deviation-to-victim ratio, the noise-to-victim ratio, and the sweep- to-victim ratio, are developed. To complement the theory, results of FM-by-noise jamming experiments conducted using commercial test and measurement equipment are presented. Specifically, the time- and frequency-domain behavior of FM-by- noise at RF and IF is studied …

Is Nipars Working As Advertised? An Analysis Of Nipars Program Customer Service, Peter F. De Kam, Dorothy J. Tribble
Theses and Dissertations
Historically, Foreign Military Sales non-standard item support has been a labor-intensive, time-consuming process. Additionally, when forced to compete for USAF resources, the foreign customer's need is often subjugated to the higher priority active USAF requirements. These problems motivated the Air Force to initiate a program to streamline procedures for the procurement of non- standard items. The program is the Nonstandard Item Parts Acquisition and Repair Support (NIPARS) program. The basic program concept is to move the management tasks for nonstandard items from USAF resources to a contractor in order to 'fix' the inefficiencies of the previous system. This thesis explores …
