The abstract provided by the Pentagon follows: The objective of this thesis is to examine the effects of source of supply and carrier on shipping times of high-priority requisitions to primary destinations of Navy units in the Pacific Theater and Persian Gulf. Our focus was primarily on determining whether source of supply, carrier, and the interaction of these two factors, have an effect on shipping times of high- priority requisitions. 'Source of supply' refers to Department of Defense supply depots and 'carrier' refers to shippers, such as Federal Express and DHL worldwide Express. This study uses ordinary least square (OLS) linear models, generalized linear models (GLM's) and nonparametric methods to explore the structure of the historical requisition datasets. OLS linear models were found to be inadequate, but both the GLM's and nonparametric tests proved to be valid and yielded results from which inferences could be made. According to the GLM's and nonparametric tests, source of supply has a statistically significant effect on shipping times of high-priority requisitions, but carrier does not. The GLM's also indicated that there is no significant interaction between source of supply and carrier.

The abstract provided by the Pentagon follows: The purpose behind this thesis was to examine the effect of vibro- tactile feedback on a user 5 degree of immersion in a synthetic environment. Sub-woofers usually provide the vibro-tactile feedback in surround sound systems. The alternate method explored in this thesis utilized a "seat shaker" to generate the appropriate tactile feedback in the environment. The solution theoretically enables the user to receive a compelling, multi-modal presentation of the environment with deployable (small footprint), unobtrusive equipment. Physiological responses (electrodermal activity, heart rate, and temperature) were measured in an attempt to determine if there was a statistically significant difference between a user 5 degree of immersion and emotional response in a 5.2 surround sound environment versus one with stereo headphones and a seat shaker.

It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A912814. The abstract provided by the Pentagon follows: The characteristic of low probability of intercept (LPI) radar makes it difficult to intercept with conventional signal intelligence methods so new interception methods need to be developed. This thesis initially describes a simulation of a polytime phase-coded LPI signal. The thesis then introduces a method for classification of LPI radar signals. The method utilizes a parallel tree structure with three separate 'branches' to exploit the image representation formed by three separate detection methods. Each detection method output is pre-processed and features are extracted using image processing. After processing the images, they are each fed into three separate neural networks to be classified. The classification output of each neural network is then combined and fed into a fourth neural network performing the final classification. The outcome of testing shows only 53%, which might be the result of the image representation of the detection methods not being distinct enough, the pre - processing/feature extraction not being able to extract relevant information or the neural networks not being properly trained. The thesis concludes with a brief discussion about a suitable method for image processing to extract significant parameters from a LPI signal.

The abstract provided by the Pentagon follows: Autonomous Underwater Vehicles (AUVs) are now being introduced into the fleet to improve Mine Warfare capabilities. Several AUVs are under government-contracted development. Mission planning and data reporting vary between vehicles and systems. This variation does not pose an immediate problem, as only one AUV is typically in operation at any given time. However, as more AUVs are put into production, cooperative operations will become possible and consistent mission commands will be necessary for multiple AUVs. Without a single mission command language, multiple systems will require multiple languages. Extensible Markup Language (XML) and related technologies may be used to facilitate interoperability between dissimilar AUVs and extract and integrate mission data into Navy C41 systems. XML makes archive maintenance easier, XML documerts can be accessed via an http server, and, in root form XML is transferable on the fly by stylesheet. This thesis presents an XML-based mission command for the command and control of AUVs. In addition, this thesis discusses XML technology and how XML is a viable means of achieving interoperability. Furthermore, this thesis provides an example mission file using existing software, and demonstrates the future of XML in AUV technology. Finally, this work provides demonstration scripts and compelling arguments for the use of an XML-based mission command language to command all AUVs.

The abstract provided by the Pentagon follows: This dissertation addresses the prediction of college student academic performance and persistence of Jefferson County Public School graduates at the University of Louisville. Using multiple regression and discriminant analysis, the research design assesses the predictive potential of six Commonwealth Accountability Testing System (CATS) scores and five college preparation variables beyond the predictive contribution of control variables established by the literature. The control variables are high school GPA, ACT score, race, sex, and socioeconomic status. The criterion variables are first semester college GPA, first year college GPA, and persistence to the sophomore year. High school GPA and socioeconomic status were statistically significant contributors to each prediction equation. CATS scores accounted for a significant proportion of variance in first year college GPA with control variables already in the equation.

It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A498214. The abstract provided by the Pentagon follows: The Department of Defense and the Department of the Air Force have funded automatic target recognition for several decades with varied success. The foundation of automatic target recognition is based upon pattern recognition. In this work, we present new pattern recognition concepts specifically in the area of classification and propose new techniques that will allow one to determine when a classifier is being arrogant. Clearly arrogance in classification is an undesirable attribute. A human is being arrogant when their expressed conviction in a decision overstates their actual experience in making similar decisions. Likewise given an input feature vector, we say a classifier is arrogant in its classification if its veracity is high yet its experience is low. Conversely a classifier is non-arrogant in its classification if there is a reasonable balance between its veracity and its experience. We quantify this balance and we discuss new techniques that will detect arrogance in a classifier. Inquisitiveness is in many ways the opposite of arrogance. In nature inquisitiveness is an eagerness for knowledge characterized by the drive to question to seek a deeper understanding and to challenge assumptions. The human capacity to doubt present beliefs allows us to acquire new experiences and to learn from our mistakes. Within the discrete world of computers, inquisitive pattern recognition is the constructive investigation and exploitation of conflict in information.
