A Delphi Forecast Of 1996 Roles: Air Force Institute Of Technology Information Resource Management Graduates Assigned To Base Level, David O. Block

Theses and Dissertations

Graduates of the Air Force Institute of Technology's Information Resource Management master's degree program who are subsequently assigned to base-level positions believe their IRM expertise is wasted in base administration roles that preclude the use of their up-to-date technical educations in managing automated information resources. This research forecasts the role AFIT IRM graduates assigned to base-level positions will need to fill by the year 1996. The research further determined what changes are necessary to resolve the perceived differences between current and forecast roles for these graduates. The Delphi survey method of forecasting was selected as an effective method of discovering …

Function Prediction Using Recurrent Neural Networks, Randall L. Lindsey

Theses and Dissertations

A fully recurrent neural network was applied to the function prediction problem. The real-time recurrent learning (RTRL) algorithm was modified and tested for use as a viable function predictor. The modification gave the algorithm a variable learning rate and a linear/sigmoidal output selection. Verifying the networks ability to temporally learn both the classic exclusive-OR (XOR) problem and the internal state problem, the network was then used to simulate the frequency response of a second order IIR lowpass Butterworth filter. The recurrent network was then applied to two problems: head position tracking, and voice date reconstruction. The accuracy at which the …

Visual Interaction: A Link Between Perception And Problem Solving, Erika Rogers, Ronald C. Arkin

Computer Science and Software Engineering

The approach taken in this research is to develop a cognitive model of how a human observer extracts information from a visual display and then uses this perceptual information in a decision-making task. Knowledge about this relationship provides information about the occurrence of perceptual events in the course of problem-solving activities, and suggests that perceptual assistance in the form of image enhancements is a useful supplement to the user’s own abilities. This knowledge is then to be embedded in an intelligent computerized assistant which is designed to facilitate and stimulate the human problem-solving process.

Domain Limitations And Interface Requirements For Expert Developed Knowledge Based Systems, Bernard Lee Lewis

Engineering Management & Systems Engineering Theses & Dissertations

The expanded use of graphical, case-based and object oriented techniques in expert systems creation has made it more practical for domain experts to develop their own applications. This thesis focuses on the elements necessary in an expert/developer interface and looks at various forms and techniques that exemplify such an approach. The spreadsheet metaphor is used for an interface or managed set of interfaces that a domain expert can use in building his own expert system or prototype. criteria are established for such interfaces and recent commercial offerings that make expert-created knowledge-bases more practical are reviewed for techniques that qualify. Approaches …

The Cognitive Status Of Risk: A Response To Thompson, L. James Valverde

RISK: Health, Safety & Environment (1990-2002)

Discussing the role that probability theory should play in Risk analysis and management, Dr. Valverde argues that Thompson's approach puts too much emphasis on the distinction between Risk subjectivism and Risk objectivism in addressing the question, "When are Risks real?"

Threatened And Endanger Species Of Wetiands And Waterways In Iowa, Kansas, Missouri, And Nebraska, Ann Burruss

United States Environmental Protection Agency: Publications

Wetlands and waterways, including perennial and intermittent streams, creeks, and rivers, are habitats for many rare animal and plant species. Wetlands in many areas continue to decline in acreage and suffer adverse impacts from conversion and development. Waterways are also under pressure from channelization and leveeing.

This study has two major components. First, a series of databases was developed that includes animals and plant species that are wetland or waterway dependent and found in Iowa, Kansas, Missouri, or Nebraska. The databases allow ready access to detailed information on each species and probable locations within each state. The plant and animal …

Heuristics For Hospital Inventory Management, Thomas G. Hibson

Theses and Dissertations

This study investigated the reasoning strategies used by hospital logistics management experts and was conducted at the Wright-Patterson AFB (WPAFB) Medical Center. An expert system was developed to verify the captured strategies. The particular area of interest of this study was the reasoning strategies involved in the reconciliation of the Monthly Stock Status Report within the Medical Logistics Branch. A literature review revealed there were few guidelines as to when and what action to pursue when reconciling the Monthly Stock Status Report. Though there were no references in the literature on expert systems that dealt with this particular report, there …

Dysfunctional Attitudes, Life Stress And Coping Processes, Deborah Desalliers

Loma Linda University Electronic Theses, Dissertations & Projects

The findings of recent investigations earmarked chronic daily stressors as being highly related to stress levels. In addition, researchers are promoting a more integrative model of stress. The stress response is no longer thought of in strictly linear terms, i.e. an event causes stress. Rather, cognitive factors, existing within the human mind itself, strongly influence our coping processes and the chronic stress we experience.

Canonical correlation analysis was used to study how dysfunctional attitudes, a negative cognitive factor, were related to individuals' daily hassles and coping processes. An increase in dysfunctional attitudes was found to correspond to an increase in …

Nonlinear System Identification Using Recurrent Networks, Hyungkeun Lee, Y. Park, Kishan Mehrotra, Sanjay Ranka

Electrical Engineering and Computer Science - Technical Reports

This paper presents empirical results on the application of neural networks to system identification and inverse system identification. Recurrent and Feedforward network models are used to build an emulator of a simple nonlinear gantry crane system, and for the inverse dynamics of the system. Recurrent networks were observed to perform slightly better than feedforward networks for these problems.

Connectionist Expert System With Adaptive Learning Capability, B. T. Low, Hochung Lui, Ah-Hwee Tan, Hoonheng Teh

Research Collection School Of Computing and Information Systems

A neural network expert system called adaptive connectionist expert system (ACES) which will learn adaptively from past experience is described. ACES is based on the neural logic network, which is capable of doing both pattern processing and logical inferencing. The authors discuss two strategies, pattern matching ACES and rule inferencing ACES. The pattern matching ACES makes use of past examples to construct its neural logic network and fine-tunes itself adaptively during its use by further examples supplied. The rule inferencing ACES conceptualizes new rules based on the frequencies of use on the rule-based neural logic network. A new rule could …

Time Delay Neural Networks And Speech Recognition: Context Independence Of Stops In Different Vowel Environments, Gregory Andrew Makowski

Masters Theses

A series of speech recognition experiments was conducted to investigate time-dynamic speech recognition of stop consonants invariant of vowel environment using data from six talkers. The speech preprocessing was based on previous studies investigating acoustic characteristics which correlate to the place of articulation (Blumstein and Stevens 1979). The place of articulation features were statistically abstracted using four moments and the energy level of the speech sample.

Both statistical and neural network pattern recognition methods were used. Statistical methods included linear and quadratic discriminant functions, maximum likelihood estimator (MLE) and K-nearest neighbors (KNN). The neural network approach used was Time Delay …

Visual Interaction In Diagnostic Radiology, Erika Rogers, Ronald C. Arkin, M. Baron

Computer Science and Software Engineering

The concept of Visual Interaction is introduced as the process which links perception and problem-solving such that problem-solving is affected by what is seen, and conversely, what is seen and perceived is affected by the current state of the problem-solving process. This paper describes the development of a cognitively-based model of the visual interaction process in diagnostic radiology, and shows how aspects of this model are being incorporated into the design and implementation of an intelligent computer-based radiological assistant. In order to achieve this, it is necessary to extract information about the nature and type of knowledge involved in this …

Indifference Graphs And The Single Row Routing Problem, Peter J. Looges

Computer Science Theses & Dissertations

This thesis investigates the subclass of interval graphs known as indifference graphs. New optimal algorithms for recognition, center, diameter, maximum matching, Hamiltonian path and domination in indifference graphs are presented. The recognition algorithm produces a linear order with properties which allow the solution of the other problems in linear time. Indifference graphs are further applied to the single row routing problem which results in both sequential,. and parallel routing algorithms.

Implications Of The Animal Rights Movement For Wildlife Damage Management, Alice P. Wywialowski

Great Plains Wildlife Damage Control Workshop Proceedings

Animal rights advocates are a vocal and active segment of the public who are likely to protest the killing of animals to reduce wildlife-caused damage. Wildlife damage management frequently involves killing damage-causing animals. Most media portrayals of wildlife damage management programs emphasize the killing of wildlife, and so inherently evoke a negative response from the public. The goals of this paper are to help wildlife damage managers better understand animal rights advocates and to suggest possible means to reduce conflicts. To meet these goals, the animal rights movement is placed in a historical perspective with regard to the animal welfare …
