Coach: A Two Level Expert Planning Assistant For High School Football, Gary F. Hasman

Theses

This thesis describes a two level expert planning system that first helps to develop a game plan for a high school football game and then aids in the selection of plays during that game. Built using Rulemaster, an expert system development tool, the system, called COACH, is initially provided observed data through the answering of questions which represents the receiving of a scouting report. This information is stored in a data file for further use. Also created during this questioning period is a data file containing comparisons of key players on the offense against their counterparts on the opponent's defensive …

Congestion Control Schemes And Their Effect On A Hypothetical Network, Jeffrey S. Reifsteck

Theses

The purpose of this thesis is to allow data communication students to experiment with various congestion control schemes to see how they will affect a simulated network. Using various parameters, the user can design a full duplex, packet switched, point-topoint virtual circuit network. Then, using this network the student can choose a congestion control scheme and run the simulation. After each run the parameter(s), the control scheme, or both, can be changed and the simulation rerun to see what the changes will do to network performance.

Distributed C++ : Design And Implementation, Pradeep P. Mansey

Theses

Distributed C++ is a learning tool developed to investigate distributed programming using the object paradigm. An extension is designed for C++, to enable the use of C++ in programming distributed applications.

Gsd - An Interactive Window Oriented Debugger, Gary Bricault S.

Theses

Each computer program, no matter how carefully designed, may contain code entry mistakes, errors in logic, and/or anomalies that can result in unexpected outcome (also known as bugs). In order to find and correct these problems, a software tool known as a debugger can be utilized by a programmer as an aid in isolating and correcting computer programs. The purpose of this thesis is to design and create such a tool for the AT&T UNIX-PC CU that will allow the user to function interactively within a window-oriented environment. This new debugger will be referred to as GSD (Graphic Symbolic Debugger). …

Computing Techniques For The Enumeration Of Cyclic Steiner Systems, Timothy Frenz Carl

Theses

In this thesis a powerful algorithm is developed for finding cyclic Steiner systems. A cyclic Steiner system with parameters S(t,k,v) is a pair ( V,B), where B is a collection of subsets all of size k (called blocks) and V is a t; element set of points, such that each t-subset of V is contained in precisely one block of B. A Steiner system is called cyclic if it has an automorphism carrying the points in a v-cycle. The results obtained so far with this algorithm are given in Table VII of chapter 5. Among the values reported there, are …

Computer Construction Of (4,4,V)-Threshold Schemes From Steiner Quadruple Systems, W. Monroe John

Theses

A construction for Sv/4 pairwise disjoint quadruple systems on u points has been given by Lindner. This thesis looks at an implementation of nearly optimal (4,4, v)threshold schemes based on his construction. These threshold schemes will have 3 v/4 keys, whereas the best implementation known to date is based on a construction given by Shamir and yields only v/4 keys. Lindner's construction depends heavily on the existence of an iV2 latin square of order v/4, thus several constructions for them have also been implemented. Unfortunately, due to the combinatorial nature of the problem, the limitations of this implementation are an …

Three-Dimensional Data Input Using Sutherland's Two-Dimensional Tablet Strategies Plus Enhanced User Feedback, Myra Bennett Pelz

Theses

Although the representation of three-dimensional computer images has become increasingly more sophisticated and complex, the problem of making three-dimensional data available to the computer continues to plague graphics systems designers. In 1974, Ivan Sutherland developed a system that defines a three-dimensional point by digitizing the same point simultaneously in two different two-dimensional views of an object. This project will implement Sutherland's system, with refinements, particularly in the area of improved user feedback.

The Dfs Distributed File System: Design And Implementation, Ananth K. Rao

Theses

This thesis describes the design of an operating system independent distributed file system (DFS) and details the implementation, on a cooperating set of server computers interconnected by means of a communications network. The DFS provides the mechanism by which the file systems of these physically dispersed units are integrated into a single logical unit. Users and application programs thus have the illusion that their files are on a single computer system, even though in reality they may be physically distributed around the network. This location transparency frees users from having to remember details such as the current location of the …

Performance Issues In Mid-Sized Relational Database Machines, Larry Sullivan

Theses

Relational database systems have provided end users and application programmers with an improved working environment over older hierarchial and networked database systems. End users now use interactive query languages to inspect and manage their data. And application programs are easier to write and maintain due to the separation of physical data storage information from the application program itself. These and other benefits do not come without a price however. System resource consumption has long been the perceived problem with relational systems. The additional resource demands usually force computing sites to upgrade existing systems or add additional facilities. One method of …

The Task Distribution Preprocessor (Tdp), Frank Mccanna

Theses

This document describes a software processor used to generate portable and efficient multiprocess programs that run on UNIX operating systems. The processor is designed to be a convenient method for converting single process C programs into distributed multiprocess C programs. Another goal is to have the processor used as a "back"end or "platform" for multitasking languages and code generators. Efficiency is targeted toward multiprocessor systems that provide facilities for sharing physical memory between processes running on separate CPUs. Portability is achieved with the use of the highly portable UNIX operating system and its companion C language. The C language is …

A Natural Language Interface To Ms-Dos, Donna Indovina Blodgett

Theses

The goal of this thesis was to design and implement a dialog facility to assist novice users of the MS-DOS operating system. A small natural language interface facility called PE-DOS (Plain English DOS) was built, which serves as a front end for a subset of simple MS-DOS commands. PE-DOS accepts English-like terminology and translates it into the appropriate MS-DOS command using a system of recursive transition networks (RTNs). The translated command then is presented to the user along with an English paraphrase of the user's input sentence in an effort to provide confirmation for the intended command in both English …

Hops: A Hierarchical/Object-Oriented Programming Environment System, Ryuichiro Kodama

Theses

The concept of object-oriented programming is becoming an important paradigm in which programmers represent and solve problems. HOPS (Hierarchical / Object-oriented Programming Environment System), developed in this thesis project, employs this concept to represent and manipulate the resources of a programming environment. All the resource objects (such as files, directories, simple integer data and so on) are hierarchically arranged for easy access and management, as the user moves through a tree structure just as in the UNIX file system. HOPL (Hierarchical / Object-oriented Programming Language), whose grammar is similar to C language, has been designed so that the expression of …

Statemaster: A User Interface Management System Based On Statecharts, Pierre Wellner

Theses

Designing and implementing a user interface (UI) is among the costliest tasks in developing interactive software systems. As a result, much work is being done in the area of User Interface Management Systems (UIMSs). These systems make it easier to develop complex user interfaces more quickly because specification of user interface dialogs is at a closer level to that at which UI designers express themselves. This paper describes the generic structure of a UIMS and several examples of previous work in the field. Many UIMSs are implemented as explicit state machines that use conventional state transition diagrams or state metaphors …

Amused: A Multi-User Software Environment Diagnostic, Mary Ann Foltman

Theses

As software projects grow in size and complexity, many individuals take over the responsibilities for one project, creating a potential for new errors in the development process. Software version inconsistency, unfamiliarity with the tools used, and software tool restrictions are but some of the problems encountered in a multi-programmer environment. These problems are not always self-evident to the programmer and may require a dedicated software support representative or experienced programmers to assist. These problems can be reduced through the development of a multi-user software environment diagnostic expert system, AMUSED (A Multi-User Software Environment Diagnostic). The AMUSED expert system is designed …

Effects Of Irradiation On The Rate Of Water Vapor Transmission Of Food Packaging Materials, Reginald L. A. Vas

Theses

Food can be preserved by irradiation which is the exposure of food to ionising radiation, high energy electron from electron beams or X-rays or gamma rays from Cobalt-60 or Cesium-137 radioisotopes. Irradiation does not leave a residue in the food and it does not make it radioactive. The low level energy levels of Cobalt and Cesium isotopic gamma rays does not induce any radioactivity. Irradiation has the same preservative effect on food as heat treatment, but because irradiation does not appreciably raise the temperature of the food, it is known as 'cold sterilization'.

Irradiation can potentially be used to preserve …

Artificial Intelligence And Mechanical Engineering, Efthimios Papayianis

Theses

Many artificial intelligence programs have been developed to assist engineers in their search for solutions. Most of them are designed to assist with a specific type of problem and they usually take the form of an expert system. However one may also use the concepts of artificial intelligence to solve a problem for which an expert system is not yet available.

Three expert systems were developed with Prolog to demonstrate how artificial intelligence can help solve problems in mechanical engineering. The first expert assists in the design of simply supported beams. The second expert assists in the design of thick …

In short, an implementation of SMI(Sample Matrix Inversion) under a parallel systolic array process is consider5ed. Also an application of utilizing systolic array on a matrix inversion is derived. As a result, it could be predicted that a VLSI chip implementation for small adaptive arrays is feasible in the near …

Co-Metabolism Of Pentachlorophenol With Glucose Using Two-Stage Anaerobic Activated Carbon Fluidized Beds, Zen Wang

Theses

Abstract - Detoxification of pentachlorophenol by using a two-stage anaerobic biological activated carbon fluidized bed has been investigated. Glucose was introduced as a cosubstrate to determine the relationship between the glucose/PCP ratio and the extent of PCP detoxification in such a system. This system has been proved to be effective in the removal of both PCP and COD. Ratio of glucose to PCP predominates the performance of the system throughout the whole course of this experiment. At a glucose/PCP ratio of 0.33, the system has a highest reduction of both PCP and COD. Addition of glucose to the highly PCP …
