Cascading Of Arithematic Coding Method With The Lzw Algorithm, Venkat R. Maram, Nageshwar R. Kadakuntla

Theses

Two known compression algorithms appropriate for communication are the LZW algorithm and the Arithmetic Coding method. Both algorithms are adaptive and require no extra communication from the encoder to the decoder. We present a scheme to cascade these algorithms into an adaptive algorithm which achieves higher compression ratio and is appropriate for communication.

Interpolation Search For Alphabetic Tables, Loizos Gabriel

Theses

One of the fastest search techniques for uniformly distributed sorted numerical tables is interpolation search. This divide and conquer technique accesses the most probable key rather than the middle key as in binary search and continues to search similarly the appropriate part of the table . In the previous work we proved a lg lg n average number of accesses for interpolation search.

The inefficiency of interpolation search for an alphabetic table is demonstrated by Burton and Lewis and a robust variation suggested by them to improve the efficiency. This inefficiency is expected since such tables are usually far from …

Cascading Lzw Algorithm With Huffman Coding : A Variable To Variable Length Compression Algorithm, Ashish Khandubhai Mehta

Theses

Two common schemes in data compression are fixed to variable length coding and variable to fixed length coding. Higher compression is expected from the more flexible scheme of variable to variable length coding. In such a scheme a compression dictionary is used to transfer variable length string over the text alphabet into variable length strings over the coding alphabet. The compression is achieved due to matching longer more frequent text strings with shorter coding strings.

To obtain a variable to variable length coding we choose to cascade the LZW , variable to fixed , coding with the Huffman , fixed …

Program Analysis Tool For Extensive Reverse Software Engineering : A Tool To Understand The Software (Patern), Bubulal R. Rawal

Theses

This thesis describes a computer aided software engineering tool called Program Analysis Tool for Extensive Reverse software eNgineering (PATERN). Conceptually, PATERN provides systems analysts/programmers with a powerful tool independent of programming language, operating system, and programmer style of coding for documenting existing software. PATERN has been tested with C code in the UNIX environment. This thesis also describes the interface between PATERN and two subsystems that interact with PATERN: relational databases and data flow diagram generators. The implementation of these interfaces was investigated using Informix and another software tool, Directed Acyclic Graphs (DAG) for generating hierarchical structure charts and flow …

Towards A Bound For The Compression Of The Lzw Algorithm, Anoop Kumar Srivastava, Shinu Gupta

Theses

The LZW algorithm is a well known efficient adaptive compression algorithm. It is based on constructing a dictionary containing character strings from the text. A number of researchers have attempted to add variations to the original algorithm to achieve higher compression values. In this thesis we attempt to find a bound for the LZW approach. That is, we build a dictionary which gives maximum compression and satisfies prefix property of LZW algorithm.

In order to build such an optimum dictionary, the dynamic programming technique is applied. The final dictionary selected consists of entries which give maximum overall compression and also …

Computer Use In The Warren County Riii School District: A Proposal For The Implementation Of A Computer Lab Program In The Elementary School, Debbie Reese

Theses

A problem faced by many schools in the 1980s is how to approach computer ir1struction in the elementary grades. Schools have moved into a new technological realm with the advent of the modern microcomputer. The focus of this project was to investigate current trends in computer education in the elementary grades in respect to computer placement within the schools and content of computer education programs. The paper addresses, specifically, the lack of a computer program in the Warren County RIII School District and the rationale for developing a computer lab in the elementary school. An interim plan is also proposed, …

Multiple-Screen Panning System, Abdo Fathy Youssef

Theses

There is a need to provide graphics capabilities for the objective of "Group Graphics". This is the ability of a group of humans to work collaboratively on the same diagram. It is the intent of this project to provide some of the fundamental software tools to allow a group of individuals to deal with a "mosaic" form of graphics made up of many separate screens that can be panned and conceptually edited by each individual who is working on portions of the overall document.

Simple tools are provided for the creation of graphics screens as well as saveing and retrieving …

Implementation Of Case (Common Application Service Element) And Application Interface For Manufacturing Automation Protocol, Amit Limaye

Theses

In 1980 General Motors formed a task force committee to explore solution to incompatibility of computer network on machine floor which control programmable devices, Robots etc. After receiving the various existing standards, the committee came up with first draft of Manufacturing & Automation Protocol (MAP 1.0) in April 1984. Further reviews resulted in different versions of MAP standards and presently, efforts are being made to come up with MAP 3.0.

MAP enables information to be readily transferred between computers, people and equipment and thus truely interconnecting open systems. The ultimate goal of these efforts is to be able to produce …

Information Retrieval In The Office For Effective Communication, Herbert Josef Schwoerer

Theses

The office worker of tomorrow, who is very likely to be an 'information-worker', will be heavily involved with communication of any kind. Effective communication, however, can only be guaranteed if the user is in control of information overload.

OIRS, the Office Information Retrieval System, designed and developed as a Master Thesis, is an approach to support the office worker in storing, maintaining, and retrieving textual information. By providing the user with a tool to impose a self-defined and self-maintained structure upon information or references to it, information overload, which is caused by lack of information about information, can be decreased. …

Some Observations On The Development Of Use Of Computer Informational Systems In Hospital Settings And Recommendations For Proposed Implementation At St. Joseph's Hospital, Andrew Z. Richardson

Theses

An intent is stated to discuss the developmental history and social impact of computer information retrieval systems on the hospital setting with primary area of focus being the Pharmacy Department. The interrelationship among various areas in the hospital setting are considered for need and cost/benefit associated with the use of a computerized information retrieval system.

A Case Study of St. Joseph Hospital is presented in example of evaluative consideration for implementation of a computerized information retrieval system.

Different forms of the "state-of-the-art" in informational systems are considered for their effective impact on cost/ benefit ratios to patient care and hospital …

A Consciousness Simulation Model, R. Edward Mitchell Jr.

Theses

The thesis titled "A Consciousness Simulation Model" by R. Edward Mitchell (1977) explores the theoretical design of a digital model aimed at simulating human consciousness. The model is structured around a collection of independent processing modules that mimic various human cognitive and emotional processes. These modules include components for thought selection, ego/achievement, memory, and emotion processing, which interact with one another in a fashion that simulates aspects of human thought and behavior.

Mitchell's primary goal is to develop a system that could behave more like a human, particularly in communication and decision-making processes, to improve human-machine interaction. The thesis highlights …
