This research is the result of an effort to provide real-time machine recognition of hand-send Morse code through the use of the M6800 microcomputer. While the capability to recognize hand-send Morse code messages by machine has been demonstrated before on large scale special purpose computers, on minicomputers, and even on the M6800 microcomputer, the main contribution of this paper is to demonstrate it with relatively understandable hardware and software.

Every business has to keep records. Sometimes these records have to be presented in a standardized form, or more often they can be arranged in any way that suits the user. Business records are of little use unless they can be referred to quickly, to provide information when it is required. In computer systems it is essential to be able to recognize any particular record in a data file which is a collection of similar records kept on secondary computer storage devices.

This paper describes multitasking facilities of Ada in concurrent and real-time programming. Synchronization and process communication mechanisms are discussed in detail, also, a new mechanism to solve the scheduling problem is developed. In the concurrent programming aspect, a comparison is made between Ada's rendezvous and Pascal's Monitor concept. In the real-time programming aspect, the differences between the Ada multitasking and the traditional "cyclic executive approaches are contrasted and their associated costs/benefits analyzed.

The purpose of this project is 1) to create a Thai character set for text processing, 2) to write a text processing program for the character set, and 3) to allow users to create and save the text.

The main purpose of this project is to compare a new sorting method- Meansort with its preceding sorting method- Quicksort. Meansort uses the mean value for each key to determine the partition of the file, but Quicksort selects at random. Experiments proved that in some ways Meansort is superior to Quicksort but is still not perfect since it always needs a mean value for each key. This project implements these two methods and determines the situations under which each of these methods outperforms the other.

The purpose of this project is to explore the alternate data structures for a disk file which is currently a preorder binary tree. specifically, the file is the key directory for an implementation of Keyed Sequential Access Method (KSAM) in a mini-computer operating system. A new data structure will be chosen, with the reasons for that choice given, and it will be incorporated into the existing system.

The Ada language is one of the most controversial topics in computer science today. Ada was originally designed as a solution to the software maintenance problems encountered by the United States Department of Defense[2], and as a multi-purpose language to be used particularly in an embedded computer system[7]. Never before has a project been undertaken. The Ada language does not simply entail the construction of a new compiler or a new language definition, it is this and a great deal more.

An interactive text editor is a computer program that allows a user to create and revise a target document such as program statements, manuscript text, and numeric data through an online terminal and the computer. It allows text to be modified and corrected many orders of magnitude faster and more easily than would manual correction. The most important characteristic of the text editor is its convenience for the user. Such convenience requires a simple, mnemonic command language which is easy to use and understand.

This paper is written to present the design purpose and design process of the Multiple Window Editor. Multiple Window Editor is a software which allows the user to edit or view different files or the same file on the screen by the window facilities provided by this software. All the windows can be dynamically created, changed, moved, and destroyed. The main purpose of this program is to improve the programming environment for the users. The design motivations will be introduced through the comparison of the present existing window facilities and the editor components. The design process will be introduced by analyzing the design decision, design tradeoffs and implementation problems.

This is a brief survey of some of the popular computer systems. As many features as possible have been covered in order to get an overview of the systems under consideration.

In this paper, five different sorting methods will be discussed. Each method will be analyzed and discussed in detail pointing out its efficiency, weaknesses, powerfullness, and the appropriate type of applications. The different methods are represented graphically using Turbo Pascal where one pass is performed in each method at a time. The methods discussed in this project are, Bubble Sort, Quick Sort, Heap Sort, Shell Sort, and Double Selection Sort. The latter is a new method that I modified from the Selection Sort. Finally, comparisons between the sorting methods mentioned above will be discussed.

This is a report concerning the project I completed for my 590 (special problem) credit. The subject of this project was a system for interactive practice room scheduling by music students at NTSU. This system was created in the fall semester of 1982 as a class project for software Development (CSCI 553) with Dr. Irby. The system was not completely finished, and I received permission from Dr. Irby to finish it and help implement its use at the Music department. I was able to observe three usages of the system: Spring, Summer I, and Summer II semesters of 1983. This report details the problems encountered during each of these usages, and changes made to the system due to them. Results of a first-use survey, under documentation, and complete final code listings were also included.

In this paper the DBase II query language of an RDBMS for personal computers is discussed. Other languages will be provided by large and sophisticated DBMS will not be discussed here. The reason for selecting the DBase II query language for discussion are as follows: 1. It is a simple language that can be learned easily [TOWN 84, DINE 84]. Within a short period, users can learn all of the facilities and manage the system very well. 2. It is a language suitable for interactive programming and execution like BASIC. 3. It provides adequate facilities for a small data base system and serves as an introductory guide for more sophisticated systems.

No matter how extended the use of the computer is, the printed document is still the primary medium for the presentation information, and will continue to be for some time. The use of computing facilities for preparation and production of the document is becoming as prevalent as their use for numeric computation. Commercially, document preparation systems are now a standard facility at research institution, and they have become quite common on each computer program. A conventional document preparation system usually contains two parts: a text editor used to create, enter, update, and maintain the text and control words that comprise the document in its "input" form, and a text formatter used to process that input and produce the final document.

Among the early applications of computers, one can find frequent mention of intelligent instructional systems. Such intelligent instructional systems represent a new generation of learner-based computer aided instruction, preceded in time by the original frame-based systems and an intervening generation of expert-based CAI. The history of CAI is characterized by three generations: Frame-based CAI, Expert-based CAI and Learner-based CAI.

It is frequently considered to be apparent two stages during assembly time. The first is the preprocessor stage in which a single instruction called the micro instruction is replaced with the sequence of instructions called the macro definition. The second is the processor stage in which the output from the first stage is assembled into machine language instructions for a particular computer. This paper descibes the first one which is macro-preprocessor stage.

In my Problem in Lieu of Thesis I explored the use of analogy in my work. I searched for ways to heighten the difference or distance between the imagery within an analogous relationship and yet maintain meaningful similarities or relationships. An analogy, for the purpose of this paper is defined as the following: "a similarity or likeness between things in some circumstances or effects, when the things are otherwise entirely different."

In this investigation I use the term perception as Arthur Comb and Donald Snygg do when they state that perception is any differentiation the individual is capable of making in his personal field. Perception has to do with the organization one gives to his world. Behavior and learning are products of perceiving. Immanuel Kant said: "We see things not as they are but as we are." During this effort to organize my world I realized that I was concerned with myself as an experiencing individual. I felt that one is built out of his experiences and that the best vantage point for understanding behavior is from the internal frame of reference of the individual himself. I was taking a somewhat phenomenological approach to my problem.

This report documents the changes in my work as a ceramic artist over a two-year period, imposed upon, and inspired by, the use of a propane torch on the surface of the clay vessel. The purpose of this study is two-fold: (1) to provide information about this particular tool for methods of survace decoration; (2) to provide information about a subjective thought process directed by properties in this particular tool.

As my creative project, I decided to explore the possibilities for expression of rhythmic life-growth patterns in a variety of abstracted multiple forms. The work was planned to investigate the following questions: 1. What forms can be used to communicate the idea of repetitive, rhythmic or seasonal life or growth patterns? 2. What size/scale is effective in communicating the universal, infinite character of these patterns? 3. What formats or types of presentation are the most effective? 4. How is the overall impact of the work affected by changes in size and form? 5. How do changes in the work affect my responses to it, and what subsequent directions result in the work?

My research explored the possibilities of achieving the raku halo through variations of the standard engobe (pronounced on-gobe) and oxide formulas, using ceramic vessels as media. This included alterations of the ingredients, consistencies, and methods of application. Throughout the research, a journal was kept including individual information about research pieces, a statement of results, and my reaction to those effects. From this information, an analysis of the completed vessels was compiled.

In pursuit of the project, I sought to address the following concerns: 1. Which intaglio processes, or their combination, proved to be the most useful in production of the book? 2. In establishing a concept for the book, what problems were encountered? 3. What is the visual relationship between the printed images, the book, and its container?

My work dealt with the life within inanimate objects and what occurred when one placed apparently unrelated objects together in an arrangement. The arrangements had three interrelated elements: the objects, spacial relationships, and materials.

Feline images have been an element in much of my work since 1981. These cat images were usually included in self-portraits. As my work progressed, the feline images increased in importance until 1985, when I abandoned the self-portraits almost entirely and began working predominantly with the cats. Although the feline image has been an important aspect of my work for several years, I never attempted to discover what these images symbolized or meant. I rarely thought consciously about the content of my work, as i arrived at my images primarily in an intuitive manner.
