An Information Visualization Solution For The Analysis Of The Afm Simulation Output Data, Stuart H. Kurkowski

Theses and Dissertations

With the advancement of computer hardware and software computer simulations are now able to run faster and track more elements than ever before burdening the analyst with more and more data to analyze. Air Mobility Command's (AMC) Airlift Flow Model (AFM) is the Air Force's logistics simulator that simulates multi-day mobility scenarios in a matter of minutes producing megabytes of output data. Because the analysts' needs for summaries, trends, and comparisons of the data have surpassed the capabilities of current desktop spreadsheet analysis techniques new tools are needed.


A Formal Methodology And Technique For Verifying Communication Protocols In A Multi-Agent Environment, Timothy H. Lacey Mar 2000

A Formal Methodology And Technique For Verifying Communication Protocols In A Multi-Agent Environment, Timothy H. Lacey

Theses and Dissertations

As network bandwidth increases, distributed applications are becoming increasingly prevalent. Systems using these applications are very complicated to build and must be dependable. Software agents are ideal for breaking complicated problems into manageable subtasks. Agent conversations, a series of messages passed between agents, are the cornerstone of multi-agent systems and must be deemed correct before being placed into service. The purpose of this research was to develop a formal methodology and technique to verify that the communication protocols defined in a multi-agent environment were valid. This was accomplished by examining agent conversations before deploying the system. An additional goal of …

Three-Dimensional Data Visualization Of Electronic Military Intelligence Using The Project Broadsword System, Michael L. Goeringer Mar 2000

Three-Dimensional Data Visualization Of Electronic Military Intelligence Using The Project Broadsword System, Michael L. Goeringer

Theses and Dissertations

Today's military electronic infrastructure solves many problems while creating others. Using computers, battlefield and global awareness is brought to bear through the near real-time linking of sensor platforms from around the globe. These intelligence networks produce vast amounts of data that must be parsed, interpreted, digested and stored by information gathering systems. As the amount of intelligence data continues to increase, these text-based systems become cumbersome and inadequate. To ensure vital information is not overlooked or discovered too late, other forms of intelligence product management and data navigation need to be investigated. This thesis explores procedures for enhancing the capabilities …


Generating Executable Persistent Data Storage/Retrieval Code From Object-Oriented Specifications, Steven R. Buckwalter Mar 2000

Generating Executable Persistent Data Storage/Retrieval Code From Object-Oriented Specifications, Steven R. Buckwalter

Theses and Dissertations

This research creates a methodology and corresponding prototype for the transformation of object-oriented (OO) specifications to represent the corresponding relational schemas that are used to automatically generate database design language (DDL). The transformation design decisions and specifications are then used to generate database manipulation language (DML) that can be embedded within the software application code generated from the same OO specifications. This concept of developing a model for producing compilable and executable code from formal software specifications has long been a goal of software engineers. Previous research at the Air Force Institute of Technology (AFIT) has not focused on the …

School of Computer Science & Engineering Faculty Publications

It has been a decade since Computer Ethics came into prominence within the field of computer science and engineering, changing not only the profession but the classroom as well. The commercialization and globalization of the World Wide Web has impacted us all, both producers and consumers alike. What was once the province of the few has become the virtual society of the multitudes. Ethical issues concerning security, privacy, information, identity, community and equity of access once contained and localized, have assumed additional complexity in the global environment. Every day, the front pages of our newspapers and magazines report violations of …


Formal Object State Model Transformations For Automated Agent System Synthesis, David W. Marsh Mar 2000

Formal Object State Model Transformations For Automated Agent System Synthesis, David W. Marsh

Theses and Dissertations

Automated agent system synthesis is the process of generating code from a requirements specification with appropriate inputs from the software engineer. Object-oriented (OO) specifications are frequently used to model intelligent software agent systems and software requirements in general; formal representations capture precisely the intentions of the specifier. Portions of OO specifications can be classified as the structural, functional, and state (or dynamic) models; major strides have been taken in the development of transformations for creating code from formal OO specifications, specifically the structural and functional aspects, and are captured within the AFIT Wide-Spectrum Object Modeling Environment (AWSOME). This research creates …


A Component Based Approach To Agent Specification, David J. Robinson Mar 2000

A Component Based Approach To Agent Specification, David J. Robinson

Theses and Dissertations

The Air Force, as well as all of industry, is currently faced with the problem of having to produce larger and more complex software systems that run efficiently and reliably as well as being extensible and maintainable. This research addresses this problem by developing a knowledge representation language that can be used to unambiguously specify and design software systems in a verifiable, efficient, and understandable manner. The language is a combination of object-oriented and component-based methodologies and makes use of both graphics and text to represent information. Although designed for the development of any type of software system, the language …


Designing Human-Centered Automation: Tradeoffs In Collision Avoidance System Design, Michael A. Goodrich, Erwin R. Boer Mar 2000

Designing Human-Centered Automation: Tradeoffs In Collision Avoidance System Design, Michael A. Goodrich, Erwin R. Boer

Faculty Publications

Technological advances have made plausible the design of automated systems that share responsibility with a human operator. The decision to use automation to assist or replace a human operator in safety-critical tasks must account for not only the technological capabilities of the sensor and control subsystems, but also the autonomy, capabilities, and preferences of the human operator. By their nature, such human-centered automation problems have multiple attributes: an attribute reflecting human goals and capabilities, and an attribute reflecting automation goals and capabilities. Although good theories exist that describe portions of human behavior generation, in the absence of a general theory …

Alternate Path Routing For Multicast, Daniel Zappala Mar 2000

Alternate Path Routing For Multicast, Daniel Zappala

Faculty Publications

Alternate path routing has been well-explored in telecommunication networks as a means of decreasing the call blocking rate and increasing network utility. However, aside from some work applying these concepts to unicast flows, alternate path routing has received little attention in the Internet community. We describe and evaluate an architecture for alternate path routing for multicast flows. For path installation, we design a receiver-oriented alternate path protocol and prove that it reconfigures multicast trees without introducing loops. For path computation, we propose a scalable local search heuristic that allows receivers to find alternate paths using only partial network information. We …

Techniques For Effectively Exploiting A Zero Overhead Loop Buffer, Gang-Ryung Uh, Yuhong Wang, David Whalley, Sanjay Jinturkar, Chris Burns, Vincent Cao Feb 2000

Techniques For Effectively Exploiting A Zero Overhead Loop Buffer, Gang-Ryung Uh, Yuhong Wang, David Whalley, Sanjay Jinturkar, Chris Burns, Vincent Cao

Gang-Ryung Uh

A Zero Overhead Loop Buffer (ZOLB) is an architectural feature that is commonly found in DSP processors. This buffer can be viewed as a compiler managed cache that contains a sequence of instructions that will be executed a specified number of times. Unlike loop unrolling, a loop buffer can be used to minimize loop overhead without the penalty of increasing code size. In addition, a ZOLB requires relatively little space and power, which are both important considerations for most DSP applications. This paper describes strategies for generating code to effectively use a ZOLB. The authors have found that many common …

Infofilter: Supporting Quality Of Service For Fresh Information Delivery, Ling Liu, Calton Pu, Karsten Schwan, Jonathan Walpole Feb 2000

Infofilter: Supporting Quality Of Service For Fresh Information Delivery, Ling Liu, Calton Pu, Karsten Schwan, Jonathan Walpole

Computer Science Faculty Publications and Presentations

With the explosive growth of the Internet and World Wide Web comes a dramatic increase in the number of users that compete for the shared resources of distributed system environments. Most implementations of application servers and distributed search software do not distinguish among requests to different web pages. This has the implication that the behavior of application servers is quite unpredictable. Applications that require timely delivery of fresh information consequently suffer the most in such competitive environments. This paper presents a model of quality of service (QoS) and the design of a QoS-enabled information delivery system that implements such a …


Cataloging Expert Systems: Optimism And Frustrated Reality, William Olmstadt Feb 2000

Cataloging Expert Systems: Optimism And Frustrated Reality, William Olmstadt

E-JASL 1999-2009 (Volumes 1-10)

There is little question that computers have profoundly changed how information professionals work. The process of cataloging and classifying library materials was one of the first activities transformed by information technology. The introduction of the MARC format in the 1960s and the creation of national bibliographic utilities in the 1970s had a lasting impact on cataloging. In the 1980s, the affordability of microcomputers made the computer accessible for cataloging, even to small libraries. This trend toward automating library processes with computers parallels a broader societal interest in the use of computers to organize and store information. Following World War II, …

Separating Touching Objects In Remote Sensing Imagery: The Restricted Growing Concept And Implementations, Leen-Kiat Soh, Costas Tsatsoulis Feb 2000

Separating Touching Objects In Remote Sensing Imagery: The Restricted Growing Concept And Implementations, Leen-Kiat Soh, Costas Tsatsoulis

School of Computing: Faculty Publications

This paper defines the restricted growing concept (RGC) for object separation and provides an algorithmic analysis of its implementations. Our concept decomposes the problem of object separation into two stages. First, separation is achieved by shrinking the objects to their cores while keeping track of their originals as masks. Then the core is grown within the masks obeying the guidelines of a restricted growing algorithm. In this paper, we apply RGC to the remote sensing domain, particularly the synthetic aperture radar (SAR) sea ice images.
