Maintenance Resources Evaluation Technique, Jorge Guarnieri Mar 1999

Maintenance Resources Evaluation Technique, Jorge Guarnieri

Theses and Dissertations

The Argentine Air Force (AAF) has undertaken the task of reviewing its logistics doctrine with the aim of supporting its mission on the basis of better-designed resource structures. The adequate sizing of logistics support is essential to obtain the desired military capability, while optimizing resource use. A decision support tool tailored to the AAF environment is needed to size that logistics support. This research developed a mathematical logistics model to evaluate the mean number of aircraft that can be restored in a given time interval between consecutive sorties, for a given maintenance resources mix and base physical geometry. This maintenance …


A Modeling And Simulation Approach To Analyze The Workload Associated With The Growth Of Network Router Access Control Lists, Douglas R. Lomsdalen Mar 1999

A Modeling And Simulation Approach To Analyze The Workload Associated With The Growth Of Network Router Access Control Lists, Douglas R. Lomsdalen

Theses and Dissertations

Organizations can no longer isolate their networks from the rest of the world and still remain competitive. An organization willing to compete in the world market must take the necessary precautions to protect its network, the systems located on those networks, and its mission critical data. There are performance issues associated with the use of access control lists (ACL); however, if ACLs are implemented properly and periodically reviewed, a secure network can be attained. This research attempts to determine how the growth of an ACL affects packet flow and router CPU consumption, and also identify the specific length of an …


Non Co-Operative Detection Of Lpi/Lpd Signals Via Cyclic Spectral Analysis, Andrew M. Gillman Mar 1999

Non Co-Operative Detection Of Lpi/Lpd Signals Via Cyclic Spectral Analysis, Andrew M. Gillman

Theses and Dissertations

This research proposes and evaluates a novel technique for detecting LPI/LPD communication signals using a digital receiver primarily designed to detect radar signals, such as a Radar Warning Receiver (RWR) or an Electronic Support Measures (ESM) receiver. The proposed Cyclic Spectrum Analysis (CSA) receiver is a robust detector that takes advantage of the spectral correlation properties of second-order cyclostationary signals. A computationally efficient algorithm is used to estimate the Spectral Correlation Function (SCF). Using state-of-the-art FFT processing, it is expected that the proposed CSA receiver architecture could estimate the entire cyclic spectrum m approximately 0.6 ms. The estimate is then …


Application Of The Finite Element Method To The Scattering Of A Two-Dimensional, Semi-Infinite Periodic Structure, Perry N. Villanueva Mar 1999

Application Of The Finite Element Method To The Scattering Of A Two-Dimensional, Semi-Infinite Periodic Structure, Perry N. Villanueva

Theses and Dissertations

Infinite periodic structures have been studied heavily because of their efficient filtering capabilities. They generally exhibit sharp frequency roll-offs at the frequency band of interest. In the RF region of the electromagnetic spectrum, periodic structures find applications such as radomes and photonic bandgap materials. Most studies have been done with infinitely periodic arrays because it is convenient to collapse an infinite array into one representative period using Floquet Analysis. Truncating an infinite array introduces an edge and invalidates Floquet analysis over the entire array. This thesis formulates a Finite Element Method (FEM) solution of a semi-infinite periodic array consisting of …

Kenneth P. Emory And “Herbert C. Shipman Cave”: A Long-Standing Puzzle Solved, Kevin Allred, Stephan Kempe, W. R. Halliday Mar 1999

Kenneth P. Emory And “Herbert C. Shipman Cave”: A Long-Standing Puzzle Solved, Kevin Allred, Stephan Kempe, W. R. Halliday

Pacific Studies

On 13 and 14 September 1945, Kenneth P. Emory of the Bishop Museum investigated what he later termed “Herbert C. Shipman Cave,” twelve miles from Hilo in the northern Puna District of Hawai‘i Island. His typescript of this investigation is frequently cited, but the cave remained unidentified until recently. In 1996 a Hawaii Speleological Survey team located a signature of Emory in the upper part of Keala Cave, at the site of a 1945 newspaper fragment previously found by another Hawaii Speleological Survey team. Other pukas explored and described by Emory as part of “Herbert C. Shipman Cave” unmistakably are …

Colombia's Three Wars: U.S. Strategy At The Crossroads, Gabriel Marcella Dr., Donald E. Schulz Dr. Mar 1999

Colombia's Three Wars: U.S. Strategy At The Crossroads, Gabriel Marcella Dr., Donald E. Schulz Dr.

Books, Monographs & Collaborative Studies

Colombia is the most troubled country in the Western Hemisphere. Drug criminals, guerrillas, and paramilitary groups are feeding a spiral of violence that makes "colombianization" a metaphor for a failing state. The authors address the strategic dimensions of the crisis. It argues that Colombia's future deeply affects regional security and U.S. interests. The country's afflictions are spilling over its borders, threatening Venezuela, Panama, Ecuador, Brazil, Peru, Mexico, and the Caribbean. At the same time, Colombia is the origin of most of the cocaine and heroin entering the United States. The fear is that, if the situation continues to worsen, the …

Technology Selection For The Air Force Research Laboratory Air Vehicles Directorate: An Analysis Using Value Focused Thinking, Michael F. Winthrop Mar 1999

Technology Selection For The Air Force Research Laboratory Air Vehicles Directorate: An Analysis Using Value Focused Thinking, Michael F. Winthrop

Theses and Dissertations

A technology selection model was developed for the Air Vehicles Directorate of Air Force Research Laboratory. The model was developed and demonstrated to aid in addressing the question of what technologies Air Vehicles' should invest in to remain consistent with Air Force values. Both Value-Focused Thinking and optimization approaches were used to identify the value of Air Vehicles technology, to provide insights to Air Vehicles' decision-makers, to determine where value gaps might exist with the scored alternatives, and to determine how sensitive the model was to changes. As a demonstration of the approach, seven technologies were scored, representing all three …


A Constructive Induction Approach To Computer Immunology, Kelley J. Cardinale, Hugh M. O'Donnell Mar 1999

A Constructive Induction Approach To Computer Immunology, Kelley J. Cardinale, Hugh M. O'Donnell

Theses and Dissertations

With the increasing birth rate of new viruses and the rise in interconnectivity and interoperability among computers, the burden of detecting and destroying computer viruses is severe. This research integrated four domains: computer virus detection, human immunology, computer immunology and an automated form of machine learning called constructive induction. First, a Computer Health System, based on the public health system, was defined to improve the 'global' approach to computer virus protection. Second, a computer immune model, based on the human immune system, was defined to improve the 'local' approach to virus detection. Third, the detection component of this computer immune …


Analysis Of Usaf Battlelabs' Communication Infrastructure Over Various Protocols, Rocky A. Favorito, David M. Mcillece Mar 1999

Analysis Of Usaf Battlelabs' Communication Infrastructure Over Various Protocols, Rocky A. Favorito, David M. Mcillece

Theses and Dissertations

As a result of the doctrines exposed in the Air Force's "Global Engagement: A Vision for the 21st Century Air Force," the concept of a "Battlelab" was devised to support and develop the key warfighting capabilities needed in the next century. Although geographically separated, these labs must have the capability to exchange information with each other in a "Virtual Battlelab Environment" (VBE). Although many types of data will be exchanged, only variable-bit-rate (VBR) video and distributed interactive simulation (DIS) traffic are modeled in the VBE. The research described in this thesis utilizes a systems engineering approach to investigate the performance …


A Climatology-Based Model For Long-Term Prediction Of Radar Beam Refraction, Todd S. Pittman Mar 1999

A Climatology-Based Model For Long-Term Prediction Of Radar Beam Refraction, Todd S. Pittman

Theses and Dissertations

The National Air Intelligence Center, WPAFB, OH, needs more accurate predictions of radar beam refraction. A new mode was developed for this thesis replacing the standard atmosphere approach with raytracing and climatology. Usually a microwave radio beam bends towards the earth with a radius of curvature greater than the earth's surface. However, seasonal and climatic variations influence the bending, and at times create temperature or moisture inversions that redirect the energy along the earth's surface leaving radio holes where there is no coverage. This model uses iterative raytracing to determine the most direct path from radar to target through the …

The Times, They Are A Changing: A Review Of Raising Children In A Socially Toxic Environment, Susan M. Sheridan, Richard J. Cowan Feb 1999

The Times, They Are A Changing: A Review Of Raising Children In A Socially Toxic Environment, Susan M. Sheridan, Richard J. Cowan

Department of Educational Psychology: Faculty Publications

Rarely does a book come along that we believe to be essential reading for all psychologists, educators, child care workers, physicians, clergy, and concerned community members. Garbarino’s Raising Children in a Socially Toxic Environment is one such book. In this book, Garbarino sets out to offer his views on what childhood ought to be, how children map their own worlds (thus define, themselves), what their basic needs are, the levels in which those needs are being met, as well as offer suggestions for ways in which readers can change the “toxic environment” to aid in the healthy development of children …
