Air Force Satellite Control Network
Originally designed in the late 1950s, the Air Force Satellite Network (AFSCN) was activated to support the Discoverer Program. Now the AFSCN provides global support for over 80 communication, navigation, missile warning, and meteorological satellites and other satellite systems for the DoD and Air Force. It has the flexibility to support Low-, Medium-, and High-altitude satellites operating in various orbits. The AFSCN is comprised of two satellite control centers, eight Remote Tracking Stations, a test facility, and a communications network linking it all together.This research paper demonstrates that the AFSCN is a force multiplier, and the center of gravity for military space operations, which needs increased security measures and upgrading. The AFSCN provides command and control capabilities for satellites that enhance several principles of war which regional commanders use to their advantage to shape the battlefield. The AFSCN faces the threats of terrorism, frequency intrusions, aging infrastructure, and budgetary constraints. In order to ensure the future of the AFSCN these threats need to be addressed. The DoD and the Air Force need to address these AFSCN threats by increasing security measures, re-writing operations orders, diplomatic relations, upgrading the infrastructure, and creating AFSCN interoperability. Taking these measures will ensure future survivability and sustainment of the AFSCN.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Full Motion Video
This paper focuses on the capabilities of an emerging imagery medium known as Full Motion Video (FMV) and its potential to improve operational and intelligence support to all levels of warfare. While not a new technology, having been used on news helicopters for years, the US Air Force first successfully employed FMV sensors on the RQ-1 Predator remotely-piloted aircraft/unmanned aerial vehicle (RPA/UAV) over the Balkans in 1995. In spite of the exceptional success of numerous deployments throughout the Balkans and the Middle East over the past decade, the capabilities of the FMV sensor have not reached their full potential. This thesis evaluates this new imagery medium and its potential to provide near real-time situational awareness as well as improved command to tactical and operational warfighters at the same time that it provides four-dimensional imagery information to the imagery intelligence community.The key question this paper attempts to answer is, "How does the Tasking, Processing, Exploitation, and Dissemination (TPED) construct need to evolve to include and support the FMV medium?" In order to address the question, the study explores the background of the Predator program, establishes the baseline TPED construct, analyzes how well FMV fits within that construct, and offers suggestions regarding how that construct must change to best leverage the FMV medium.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Airlift 2025
The Chief of Staff of the Air Force, General Ronald R. Fogleman, has directed the Air University to conduct a major study on air and space power and concepts applicable to the year 2025 and beyond. This will include examination of innovative systems, new concepts of operations, and the emerging technologies enabling them. The study formally commenced in August 1995 when the students arrived for the Air University 1995-1996 academic year and will conclude in June 1996 with delivery of the final report to the Chief of Staff of the Air Force. The final report will be a logically ordered collection of white papers developed from the innovative concepts and technology abstracts submitted.Power projection is critically dependent on mobility forces. The air mobility system should be capable of supporting national objectives from humanitarian, non-hostile operations through armed conflict. Because of operational constraints that include evolving threats and reduced external infrastructure, the airlift system in the year 2025 should be independent of theater basing structure. International political changes will likely necessitate the basing of most, if not all, US military forces in the continental United States (CONUS). However, this will not end the requirement for a global US presence. Although the probability of direct foreign military threats to our interests may be slight, Air Mobility Command (AMC), the air transportation arm of US Transportation Command, must be prepared to conduct global air mobility on a daily basis. In addition, AMC must continue to support humanitarian and peacekeeping missions in both benign and hostile environments. These expanding requirements demand attention. This paper proposes technologically feasible concepts to meet the air mobility requirements posed by probable US national objectives in the year 2025.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Saved by Iridium? An Alternative to GPS
The Department of Defense (DoD) has depended on different space-based assets as critical components to battlefield operations. As technology has evolved, space-based assets have become the eyes and ears of the military. Unfortunately, these assets have become one of the most vulnerable U.S. infrastructures. In 1995, the U.S. Global Positioning System (GPS), a complex and sophisticated space-based asset, became fully operational, providing accurate, reliable, and secure information on position, navigation, and timing to the joint force. The joint force uses GPS navigation to locate objectives and coordinate movement of ground forces and supplies. In addition, cruise missiles, smart bombs, and artillery projectiles currently use GPS to guide them to enemy target coordinates. GPS also provides a timing element that has become critical for the military in communications, computer networks, combat planes, and Unmanned Aerial Vehicles. Space-based technologies reach down into everyday military activity, so interrupting service immediately degrades operations. GPS capabilities are great and adversaries may be quick to deny or degrade them. Currently, there is not an alternative to GPS for ground, air, sea, or space operations. The methods of operating with a degradation or loss of GPS are contingent on the type of operation, whether it is land, sea, air, or space; as the current backup alternatives to GPS can only support one operation at the time. For this reason, it is critical for the joint force to have at least one backup alternative. At this time, the only alternative appears to be space-based, as a space-based alternative can provide simultaneous global coverage more affordably and accurately on PNT to the entire joint force. The most feasible potential space-based alternative to GPS is the existing commercial Iridium system, a sixty-six satellite communication constellation in low-earth orbit, under a program known as the high integrity GPS or iGPS.

Creep Performance of Oxide Ceramic Fiber Materials at Elevated Temperature in Air and in Steam
The effects of steam on the creep performance for several ceramic materials were investigated at temperatures in the 1100-1300-C range. Experimental programs were designed to explore both tensile and compressive creep behaviors as well as the response in monotonic tension. Subcritical crack growth was determined to be the dominant failure mechanism in ceramic fibers at elevated temperatures in steam. The creep life prediction analysis of ceramic fiber tows was performed using linear elastic fracture mechanics and a power-law crack velocity model. Additionally, the effects of steam at 1300-C on creep performance of high-purity polycrystalline yttrium aluminum garnet (YAG) were studied. The high temperature mechanical properties of polycrystalline YAG make it the most promising candidate material oxide material for the next generation ceramic fiber.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Lasers and Missile Defense
weapons? Recent advances in lasers, optics, and spacecraft technologies may bring high-energy laser weapons to a sufficient level of maturity for serious consideration as space weapons against the theater ballistic missile threat. However, these technological advances also make other architectures possible, such as the use of terrestrial laser sources with space-based relay mirrors or a mixed force of space-based lasers with orbiting relay mirrors. An important question is how these dramatic technology improvements have affected the strategic employment concepts for high-energy laser weapons. This study presents a comparison of competing space-based architectures given the progress made with high-energy lasers, large optics, and atmospheric compensation techniques within the past several years. Three space-based architectures are evaluated against the potential ballistic missile threat: space-based lasers, ground-based lasers in conjunction with orbiting mirrors, and a combined approach using space-based lasers with orbiting mirrors. The study evaluates the technological risks and estimates the development and deployment costs. In addition, technology development programs are described for each of the architectures so that the high-risk areas will be better understood. The conclusion of this study is that the most technologically sound and cost-effective architecture is to use space-based lasers with orbiting mirrors. This approach not only minimizes the overall technological risk but also reduces the total weight and, therefore, cost of placing these weapon systems on orbit.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

2025 Operational Analysis
In the summer of 1995 the Air Force chief of staff tasked Air University to do a year-long study, 2025, to "generate ideas and concepts on the capabilities the United States will require to possess the dominant air and space forces in the future [, to] detail . . . new or high-leverage concepts for employing air and space power [, and to] detail . . . the technologies required to enable the capabilities envisioned." To support this goal a 2025 study team conducted an operational analysis to identify high-value system concepts and their enabling technologies in a way that was objective, traceable, and robust. This analysis determined which of the 2025 system concepts show the greatest potential for enhancing future air and space capabilities and which embedded technologies have the highest leverage in making the high-value system concepts a reality.The team developed a model, Foundations 2025, which reflected the overall values held by the 2025 participants. The purpose of the model was to quantify and compare different system concepts' contributions to future air and space capabilities. Foundations 2025 is distinguished by the large number of system concepts that can be analyzed, the 30-year focus into the future, and the fact it was developed through a bottoms-up approach. Foundations 2025 offers a potential new framework for future air and space doctrine that can be easily modified (broken into three separate models: awareness, reach, and power) by AF MAJCOMs for use in their mission area analysis process. Thus, the model presented is an aid to current and future senior decision makers concerned with the employment of air and space power. The 2025 study produced a number of excellent system concepts for employing air and space power in the future. Analysis of the highest-value system concepts indicated that the effort to occupy the "high ground" of the future will require air and space forces to possess increased awareness and to control the mediumThis work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Creep and Fatigue Interaction Characteristics of PWA1484
One of the main methods for predicting the service life of jet engine turbine blades is through creep analysis. A sample of the turbine blade material will be mechanically tested to characterize its creep performance. This characterization will be used to determine safe operating conditions for the material. While methods for modeling creep behavior are generally well developed, this constant load creep testing does not fully represent the loading conditions present in a jet engine due to cyclic loading caused by the mission profile and throttle movements. As the industry seeks to become more accurate in physics based modeling of materials that are used in turbine blades, incorporation of these cyclic loads into the characterization of turbine blade materials is needed. It will be important to understand what effect pre-existing creep will have on fatigue life and what effect pre-existing fatigue loading will have on creep life. This research gives microstructural observations as well as data analysis of samples of PWA1484 tested at 871-C in creep-fatigue environment. This research resulted in the conclusion that prior fatigue cycling results in a non-linear reduction in the amount of primary creep, and an earlier transition to tertiary creep in PWA1484.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

At the Crossroads of Cyber Warfare
This thesis provides signposts to guide the Royal Australian Air Force during its journey through the development of a cyber capability. As with most journeys, there are always multiple paths; the challenge is to choose a path that will deliver an effective cyber force with the available resources. The emergence of cyberspace changed the character of war in ways Clausewitz could never have imagined. Cyber violence transcends the physical environment, creating effects on an adversary's warfighting capabilities as severe as a kinetic weapon. Uncertainty, the fog that envelopes all aspects of conflict, remains ever-present; however, cyber enables commanders greater situation awareness, shifting the shade of fog from opaque to translucent.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Environmental Life Cycle Assessment of Coal-Biomass to Liquid Jet Fuel Compared to Petroleum-Derived JP-8 Jet Fuel
The United States (U.S.) imported 57 percent of the petroleum products that it consumed in 2008. The Department of Defense (DOD) and in particular, the United States Air Force (USAF), consumes a large amount of oil to support the mission of defending the U.S. According to the USAF energy policy, by 2016, the Air Force (AF) must be prepared to cost competitively acquire 50 percent of its domestic aviation fuel requirement via an alternative fuel blend in which the alternative component is derived from domestic sources produced in a manner that is "greener" than fuels produced from conventional petroleum. This study employed a life cycle assessment (LCA) tool known as Economic Input-Output Life Cycle Assessment (EIO-LCA) to compare the petroleum derived jet fuel of JP-8 to the alternative jet fuel of Coal-Biomass to Liquid (CBTL) to determine which was "greener" by determining the total global warming potential (GWP) over each jet fuels' entire life cycle. The CBTL jet fuel was determined to be "greener" for the environment with utilizing carbon capture and storage (CCS) via the Fischer Tropsch (FT) synthesis process when producing liquid jet fuel from coal and swithchgrass as the biomass.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Quality of Quantity
The U.S. Army, after years of false starts and unfilled promises, is about to make good on its commitment to field an unmanned aerial vehicle system at the maneuver brigade level. Called the Shadow 200 tactical UAV (TUAV), it promises to dramatically enhance the reconnaissance, surveillance, target acquisition (RSTA) capabilities of those at the tip of the proverbial spear by providing them the ability to gather information on enemy formations with a limited risk to men and materiel. For approximately $3million, this program will put three aircraft, and associated support systems, in the hands of each brigade to fulfill those dull, dirty, and dangerous reconnaissance tasks currently challenging the brigade's reconnaissance and surveillance architecture. As compelling as this capability promises to be, the question remains as to whether the Shadow TUAV is the right tool for the wrong job. This monograph asks should the U.S. Army alter its current UAV acquisition strategy for maneuver brigades from one in which limited numbers of high capability systems are acquired, in favor of another that fields a large quantity of less capable mini-UAVs? A UAV system built around mini-UAVs, essentially smaller, less capable, but much cheaper versions of the more conventional aircraft, has inherent strengths that support its adoption at the brigade level. As a system, the sheer quantity of deployed collection assets, inherent design austerity, and flexible organization give them a significant advantage in fulfilling the requirements of a brigade level UAV system than their more conventional UAV cousins. They will allow a future prospective brigade commander to see more, with more, at less overall cost. To support this conclusion, this monograph will analyze the strengths and weaknesses of both the current UAV acquisition plan and a proposed mini-UAV strategy, compare the two systems in relation to the design parameters established for a brigade level UAV, then marry the results ofThis work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

A Framework for Prognostics Reasoning
The use of system data to make predictions about the future system state, commonly known as prognostics, is a rapidly developing field. Prognostics seeks to build on current diagnostic equipment capabilities for its predictive capability. Many military systems, including the Joint Strike Fighter (JSF), are planning to include on-board prognostics systems to enhance system supportability and affordability. Current research efforts supporting these developments tend to focus on developing a prognostic tool for one specific system component. This dissertation research presents a comprehensive literature review of these developing research efforts. It also develops presents a mathematical model for the optimum allocation of prognostics sensors and their associated classifiers on a given system and all of its components. The model assumptions about system criticality are consistent with current industrial philosophies. This research also develops methodologies for combining sensor classifiers to allow for the selection of the best sensor ensemble.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Geosynthetic Design Guidance for Hazardous Waste Landfill Cells and Surface Impoundments
The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA's struggle to protect health and the environment is seen through each of its official publications. These publications outline new policies, detail problems with enforcing laws, document the need for new legislation, and describe new tactics to use to solve these issues. This collection of publications ranges from historic documents to reports released in the new millennium, and features works like: Bicycle for a Better Environment, Health Effects of Increasing Sulfur Oxides Emissions Draft, and Women and Environmental Health.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

A Methodology for Using Simulation Results for Test and Evaluation
Each year the Air Force spends billions of dollars on Test and Evaluation to ensure acquisition programs roll out the best possible products. In 1997, the National Research Council assembled to evaluate the overall procedure used in procuring various platforms with system planning, research, development and engineering (SPRDE) and program management (PM) processes. In their final report, they claimed that the full advantages of statistical practices, simulation, model-test-models, and incorporation of prior test information into current test practices have not been fully utilized. To examine one of the report's recommendations, this thesis defines and explores a methodology using simulation to augment or replace test data in lieu of operational testing. Specifically, a validated simulation model employs non-critical factor data from preliminary small sample operational testing.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Logging the JSF
Within the US Air Force, acquisition, operations, and logistics communities collectively face a perplexing question: What is the best way to plan the acquisition and life-cycle sustainment of a fighter aircraft fleet? To find the answer to this question the following thesis attempts to derive lessons learned from case study analysis to develop a new methodology for future use. Aircraft fleet size, in an acquisition program, is determined by assessing the capabilities necessary to meet current and future operational readiness demands. Aircraft sustainment, although equally important, is typically not considered during early procurement planning due to the difficulty in forecasting the sustainment infrastructure necessary to mitigate effects caused by aging and changing operational requirements. At best a nebulous endeavor, sustainment forecasting is affected by the myriad of dynamic organizational, technological, and budgetary influences caused by rigid DoD acquisition processes and inflexible Congressional appropriations cycles.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Fighter Pilot Inventory and Requirements Model
"Historically, managing fighter pilot requirements has been a continual challenge for the Air Force Personnel Center. In recent years, Unmanned Aerial Vehicles have become a highly sought after commodity, and the number of UAV billets have increased, with more increases expected in the near future. Currently 45% of UAV squadrons are manned by combat aircrew. Fighter pilots fills the majority of these slots. This dramatic increase in UAV requirements demands analysis for the impact on fighter pilot requirements. An increase in UAV fighter pilot billets represents a direct increase in force requirements, however, there may be an indirect effect on training and man year requirements."--Abstract from web site.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

High Temperature Degradation of 5250-4 Polymer Resin
5250-4 bismaleimide resin is used in high performance polymer matrix composites with high temperature aeronautical applications. This thesis investigated the thermal and oxidative degradation of 5250-4 neat resin powder in argon, air, and oxygen environments. The powder was agedat 163, 177, and 190 璽 簞C in all environments for at least 250 hours. Isothermal thermo-gravimetric analysis demonstrated that weight loss was negligible for agingin the argon environment, indicating weight loss isthe result of an oxidative process at these temperatures.The 5250-4 powder exhibited an initial period of weightgain before eventually losing weight inboth air and oxygen. The applicabilityof a closedloop oxidation scheme to 5250-4 gravimetric behavior was investigated. Kinetic parameters for the scheme were determined for the AirForce Research Laboratory's polymermatrix composite lifetime prediction modeling efforts.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

A Comparison Study of F-15C Fighter Squadron Ready Aircrew Program Flying Hour Scheduling vs. the RAND Corporation's Flying Hour Scheduling Linear Program
This research compares and contrasts the Flying Hour model created by the RAND corporation with the Ready Aircrew Program (RAP) model from Air Combat Command. The RAP model was designed to generate an annual flying hour program that specifies the minimum number of sorties required to stay tactically safe. The RAND model was designed to provide fighter pilots 13 sorties per month, a number determined from surveys of combat aviation leadership. The RAND model is built on the assumption that the fighter pilots would be immediately ready to deploy to a combat situation. In contrast, squadrons using the RAP model must take extra sorties and time to get fighter pilots ready for war. This research recommends an increase to AFI 1-2F-15V1 annual pilot requirements. This plus-up will increase average monthly sorties for combat mission ready API-1 pilots to the Air Force Safety Center recommended 11 flights per month at a flying hour cost of approximately $1.7 million per squadron.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Benign Weather Modification
Weather modification is a technology once embraced by the U.S. military as a tool to help both wartime and peacetime missions. However, interest in the ability to modify weather has waned over recent years and is now nearly non-existent. This study examines one aspect of weather modification, benign weather modification, for possible use in assisting military operations. After briefly reviewing the history and science of weather modification, this study bounds the aspects of weather modification being addressed. The study then describes barriers to benign weather modification (BWM), showing how they affect current weather modification policy in the military. Then examples are shown of current civilian BWM techniques, their possible use by the military, and some military-unique needs for weather modification. After examining current weather modification and projected future BWM technology, this study concludes that military BWM use deserves another look. Increased reliance on precision guided munitions makes BWM a possible new tool in ensuring accurate targeting with minimal collateral damage. In addition, BWM offers the warplanner a means to dictate battlespace elements at a critical point in a conflict. At a minimum, the U.S. military should conduct a more in-depth review of weather modification to see if technological advances offer opportunities for more "bang for the buck."This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

An Evaluation of a Networked Radiation Detection System
First responders assess a Nuclear/Radiological (NUCRAD) event in a timely and accurate manner by creating a site characterization that reflects the location of various levels of contamination based on their instruments' readings. The survey team experiences difficulty in accurately recording this critical data due to the challenge of operating multiple devices and communicating the devices' readings to other survey members. First responders produce a representation of the contamination or activity on a map that contain rings outlining the levels of activity and/or single locations of a single activity. Recently, several agencies began creating software programs that record a first responder's instrument readings, time, and the global positioning system (GPS) location plotting the information in real-time. The Environmental Protection Agency (EPA) Region 5 developed the Rapid Assessment Tool (RAT). This research evaluates the effectiveness of RAT by comparing the timeliness and accuracy of the site characterization created by multiple survey teams (one team not using RAT and another team using RAT). All of the Bioenvironmental Engineer (BEE) Survey Teams using RAT decreased their survey times for all scenarios. The Weapons of Mass Destruction - Civil Support Team (WMD-CST) survey teams using RAT decreased their survey times during the lane, bounce and bypass, star, and cloverleaf scenarios. However, survey times increased for the zigzag and radial scenarios.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Unmanned Systems
The Fiscal Year (FY) 2001 National Defense Authorization Act (NDAA) signed into law a mandate directing the Department of Defense (DoD) to develop and procure Unmanned Systems through FY 2030. These unmanned air, ground, and sea systems are being designed to support Full Spectrum Operations (FSO) in a hybrid-threat environment. The impact for the 2020 Joint Task Force (JTF) is that it will operate with unmanned systems that will revolutionize the way it conducts its operations. Furthermore, the 2020 JTF will be required to leverage cutting-edge information technologies that will ensure a secure and collaborative command and control network in a security environment that is increasingly competitive due to the proliferation of advanced unmanned systems. The challenge then is to posture the 2020 JTF to integrate these revolutionary unmanned systems. The essential tasks are to ensure operational reach and establish operational access throughout operations which are increasingly ready to be accomplished with revolutionary unmanned systems in lieu of manned systems.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Geolocation of an Audio Source in a Multipath Environment Using Time-of-Arrival
The Air Force and the Department of Defense (DoD) are continually searching for ways to protect U.S. forces, both stateside and abroad. One continuing threat, especially in the current world environment, is gunfire from an unseen sniper. Designated areas, such as a forward deployed base or motorcade route, need to be continuously monitored for sniper fire. Once detected, these gunmen need to be located in real time. One possible method for accomplishing this task is to geolocate the audio signals generated using time-of-arrival (TOA) algorithms. These algorithms rely on direct-path measurements for accuracy. Multipath environments therefore pose a problem when measuring signals from the audio spectrum. The errors induced by a multipath environment can be reduced by introducing additional audio receivers to the detection system. By sampling all possible combinations of a minimum set of receivers (four), a more accurate location can be calculated. An accuracy of six meters can be achieved roughly 69 percent of the time, though most of the error occurs in the vertical component. An accuracy of six meters in the X/Y plane can be achieved approximately 97 percent of the time.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Determination of the Constitutive Equations for 1080 Steel and VascoMax 300
The objective of this research is to establish a better representation of the components utilized in a gouging event being considered in research leading to a better understanding of the Holloman High Speed Test Track. Gouging occurs when two metals are traveling at a slight incline to each other at velocities nearing 1.5 kilometers per second, and results in a structural failure of both the metals. The gouging process occurs at very high strain rates, which results in non-linear stress-strain relations. The coefficients that lead to the Johnson-Cook equations have been determined by the Split Hopkinson Bar test for 1080 steel and VascoMax 300. The Split Hopkinson Bar test was conducted using various strain rates and temperatures to produce meaningful stress-strain relations for both of the steels. These relations allowed a fit of the data to yield specific material coefficients defined in the Johnson-Cook constitutive model. Both the 1080 steel and Vascomax 300 models showed excellent approximation of the plastic region. Verification of the constitutive models was conducted through the use of Taylor tests. A Taylor test model utilizing the constitutive equations was developed in CTH and produced deformation profiles that closely resembled specimens taken from experimental Taylor tests. The end result of this work will be utilized in further studies toward overall high energy impact evaluation.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Expendable Remotely Piloted Vehicles for Strategic Offensive Airpower Roles
Major Larm examines the feasibility of developing expendable remotely piloted vehicles (RPV) and explores future concepts of conventional US offensive airpower roles. He outlines the historical base of the larger category of unmanned aerial vehicles. Major Larm does not propose to take the pilot out of the cockpit, but he examines the concept of taking the cockpit out of the aircraft. By incorporating the added dimension of employing one-use vehicles to this concept, he attempts to reveal representative-though not all-encompassing-innovative airpower ideas. Major Larm's conclusion is that the use of expendable RPVs for strategic offensive airpower roles is a viable concept.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Building a True Air and Space Operations Center
"The role of space in American military operations has evolved significantly since the end of the Cold War with the theater Air and Space Operations Center (AOC) playing a major role in integrating space effects into theater warfare. Moving far beyond traditional support roles, space operations in the AOC now include the defense of friendly space capabilities from interference and attack; the offensive ability to disrupt or deny an adversary the use of space; and coordination of theater space operations. However, the organization of space operations in the AOC has not kept pace with these changes. The primary assertion in this study is that the AOC needs to reorganize space personnel in the AOC and build a robust space organization to meet the Joint Force Air Component Commander's (JFACC) expanding space responsibilities. This will help resolve ambiguities and shortfalls in the current organization of space personnel that hinder the execution of these responsibilities. Today, the Air Force is on the threshold of building a true Air and Space Operations Center that can deliver air and space effects in support of air, land, maritime, and special operations forces. While there is no perfect organizational structure, the adoption of a Space Specialty Team or Space Division construct in the AOC can improve the JFACC's ability to execute his air and space war fighting responsibilities in support of the Joint Force Commander's objectives."--Abstract from web site.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

A Framework for Prognostics Reasoning
The use of system data to make predictions about the future system state, commonly known as prognostics, is a rapidly developing field. Prognostics seeks to build on current diagnostic equipment capabilities for its predictive capability. Many military systems, including the Joint Strike Fighter (JSF), are planning to include on-board prognostics systems to enhance system supportability and affordability. Current research efforts supporting these developments tend to focus on developing a prognostic tool for one specific system component. This dissertation research presents a comprehensive literature review of these developing research efforts. It also develops presents a mathematical model for the optimum allocation of prognostics sensors and their associated classifiers on a given system and all of its components. The model assumptions about system criticality are consistent with current industrial philosophies. This research also develops methodologies for combining sensor classifiers to allow for the selection of the best sensor ensemble.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Technology Selection for Enhancing F-16 Capability
This study, with support of the Aeronautical Systems Center, builds a scientific decision support system intended for Air Combat Command. Past decision-making techniques are discussed and their limitations are explained. Two multiattribute decision-making techniques, analytical hierarch process and value focused thinking, are studied. Due to limitations of analytical hierarchy process, value focused thinking is accepted as the best fit for our problem. A value hierarchy model is developed using value focused thinking for selecting the most beneficiary F-16 engine modifications depending on anticipated Air Combat Command values. Ten modifications are ranked using value model to validate the process. Cost is involved in the rankings to show the benefit per dollar invested. Optimization techniques are used to form various effective modification sets due to changing budget constraints. Sensitivity analyses show that the model is weight sensitive. This study proves that multiattribute decision-making techniques and particularly value focused thinking approach can be used to create a scientific decision support system for Air Combat Command.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Analysis of the Economic and Environmental Effects of Compressed Natural Gas as a Vehicle Fuel, Vol. 1
The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA's struggle to protect health and the environment is seen through each of its official publications. These publications outline new policies, detail problems with enforcing laws, document the need for new legislation, and describe new tactics to use to solve these issues. This collection of publications ranges from historic documents to reports released in the new millennium, and features works like: Bicycle for a Better Environment, Health Effects of Increasing Sulfur Oxides Emissions Draft, and Women and Environmental Health.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Information Warfare
As we approach the dawn of the 21st century, success of our national security strategy will depend greatly on our ability to combat the Information Warfare (IW) threat. Old paradigms regarding conventional warfare must change to incorporate this new form of warfare. Our nation's growing dependency on information and information-based technologies has made IW a legitimate weapon for potential adversaries. The "information" and its support infrastructures are becoming extremely vulnerable to hostile attacks. Adversarial forces can now wage information-based warfare from anywhere in the world, and literally remain anonymous. Thus, our ability to recognize and defend against this new form of warfare is paramount to the survival of our national security infrastructure.The thesis of this research project is predicated upon the following premises: First, the exploitation of "information" as a weapon is changing the nature of warfare. Second, although there is much debate about the reality of the IW threat, this paper postulates that adversarial IW tactics pose a legitimate threat to our national security infrastructure. Finally, the Department of Defense (DOD), the Joint Staff, and the Services must remain actively committed to combating the IW threat in the 21st century.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

A Life Cycle Assessment and Economic Analysis of Wind Turbines Using Monte Carlo Simulation
The United States depends heavily on nonrenewable fossil fuels to generate electricity. Using renewable energy sources, such as wind, could reduce air emissions and fossil fuel dependency. Previous studies have examined the life cycle costs and environmental impacts of using wind to generate electricity, but results have varied due to inconsistent modeling assumptions. This research uses Monte Carlo simulation to conduct an economic payback analysis and life cycle assessment of 11 modern, utility-scale wind turbines. Hourly meteorological data was used to evaluate 239 U.S. locations. For each location, the wind turbine with the shortest median payback period was assumed to be the economically preferred turbine model. This simulation demonstrates that variance in the model output is primarily caused by differences in location-specific climate data (wind speed, air density). Depending on the location, the median economic payback periods ranged from 2 to 132 years. 41% of the locations had median payback periods less than 10 years, and 63% less than 15 years. Considering a typical turbine lifespan of 15-30 years, wind turbines are not economically viable at all locations. At locations with favorable wind resources, wind turbines are likely to be superior to electricity production using natural gas or coal. For the preferred wind turbine, the median life cycle energy intensities at all 239 locations ranged from 0.05-0.54 (KWh energy inputs/KWh outputs), compared to 2.3 for natural gas and 2.6-3.5 for coal-fired electricity generation. The median CO2 (eq) intensity values range from 13-156 g-CO2 (eq)/kWh for the preferred wind turbine, compared to 585 g-CO2 (eq)/kWh for natural gas and 757-1042 g-CO2 (eq)/kWh for coal-fired power plants.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Extension of Viscoplasticity Based on Overstress to Capture the Effects of Prior Aging on the Time Dependent Deformation Behavior of a High-Temperature Polymer
The inelastic deformation behavior of PMR-15 neat resin, a high-temperature thermoset polymer, was investigated at 288 degrees C. The experimental program was designed to explore the influence of strain rate on tensile loading, unloading, and strain recovery behaviors. In addition, the effect of the prior strain rate on the relaxation response of the material, as well as on the creep behavior following strain controlled loading were examined. The experimental data were modeled with the Viscoplasticity Based on Overstress (VBO) theory. A systematic procedure for determining model parameters was developed and the model was employed to predict the response of the material under various test histories. Additionally the effects of prior aging at 288 degrees C in argon on the time (rate)-dependent behavior of the PMR-15 polymer were evaluated in a series of strain and load controlled experiments. Based on experimental results, the VBO theory was extended to capture the environmentally induced changes in the material response. Several of the VBO material parameters were expanded as functions of prior aging time. The resulting model was used to predict the high-temperature behavior of the PMR-15 polymer subjected to prior aging of various durations.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
