Deception Detection: Study Of Information Manipulation Through Electronic Identity Theft-Email Forgery In The U.S. Military, Roy V. Rockwell Dec 2002

Deception Detection: Study Of Information Manipulation Through Electronic Identity Theft-Email Forgery In The U.S. Military, Roy V. Rockwell

Theses and Dissertations

This research describes the results of a field experiment which examines the effects of warnings on system trust and individual awareness in government computer systems through the use of email forgery. The experiment consisted of forging a trusted government email account and trying to get government computer users to reply to a forged email address. The results revealed that warning individuals about possible email forgery did not increase their awareness or reduce their level of system thrust in the email system nor did it increase their ability to detect email forgery. The results did determine that government computer users are …

A Combined Adaptive Tabu Search And Set Partitioning Approach For The Crew Scheduling Problem With An Air Tanker Crew Application, Todd E. Combs Aug 2002

A Combined Adaptive Tabu Search And Set Partitioning Approach For The Crew Scheduling Problem With An Air Tanker Crew Application, Todd E. Combs

Theses and Dissertations

This research develops the first metaheuristic approach to the complete air crew scheduling problem. It develops the first dynamic, integrated, set-partitioning based vocabulary scheme for metaheuristic search. Since no benchmark flight schedules exist for the tanker crew scheduling problem, this research defines and develops a Java™ based flight schedule generator. The robustness of the tabu search algorithms is judged by testing them using designed experiments. An integer program is developed to calculate lower bounds for the tanker crew scheduling problem objectives and to measure the overall quality of solutions produced by the developed algorithms.

Robustness Of Multiple Objective Decision Analysis Preference Functions, William K. Klimack Jun 2002

Robustness Of Multiple Objective Decision Analysis Preference Functions, William K. Klimack

Theses and Dissertations

This research investigated value and utility functions in multiobjective decision analysis to examine the relationship between them in a military decision making context. The impact of these differences was examined to improve implementation efficiency. The robustness of the decision model was examined with respect to the preference functions to reduce the time burden imposed on the decision maker. Data for decision making in a military context supports the distinction between value and utility functions. Relationships between value and utility functions and risk attitudes were found to be complex. Elicitation error was significantly smaller than the difference between value and utility …

Aerospace Expeditionary Force Implementation And The Effect On Team Cohesion, Michael J. Zuhlsdorf Mar 2002

Aerospace Expeditionary Force Implementation And The Effect On Team Cohesion, Michael J. Zuhlsdorf

Theses and Dissertations

A statistical analysis of deployed and deploying airmen was conducted to provide insight and defensible support for Aerospace Expeditionary Force Center commanders to base teaming initiatives and policy decisions. To ensure that the results of this research are applicable across the Air Force, the research examined the effect of the Aerospace Expeditionary Force deployment process, comprised of individual anxiety, group unity, and work-group characteristics, on team cohesion, deployment commitment, and team effectiveness. The sample obtained included 643 airmen who had deployed within a 12-month period or who were scheduled to deploy within the next 3-month period. The results of the …

Analysis Of Gps Satellite Allocation For The United States Nuclear Detonation Detection System (Usnds), Aaron J. Bell Mar 2002

Analysis Of Gps Satellite Allocation For The United States Nuclear Detonation Detection System (Usnds), Aaron J. Bell

Theses and Dissertations

We present an approach for identifying salient input features in high feature to exemplar ratio conditions. Basically we modify the SNR saliency-screening algorithm to improve the solution of the optimal salient feature subset problem. We propose that applying the SNR method to randomly selected subsets (SRSS) has a superior potential to identify the salient features than the traditional SNR algorithm has. Two experimental studies are provided to demonstrate the consistency of the SRSS. In the first experiment we used a noise-corrupted version of the Fisher s Iris classification problem. The first experiment designed to prove the fidelity of the SRSS …

Commercial Regional Space/Airborne Imaging, Ugur Akyazi, Ali Durmus, Birce Boga Bakirli, Arif Arin Mar 2002

Commercial Regional Space/Airborne Imaging, Ugur Akyazi, Ali Durmus, Birce Boga Bakirli, Arif Arin

Theses and Dissertations

In this work goal programming is used to solve a minimum cost multicommodity network flow problem with multiple goals. A single telecommunication network with multiple commodities (e.g., voice, video, data, etc.) flowing over it is analyzed. This network consists of: linear objective function, linear cost arcs, fixed capacities, specific origin-destination pairs for each commodity. A multicommodity network flow problem with goals can be successfully modeled using linear goal programming techniques. When properly modeled, network flow techniques may be employed to exploit the pure network structure of a multicommodity network flow problem with goals. Lagrangian relaxation captures the essence of the …
