Conscious / Unconscious, David M. Cravenho

Theses

I am an artist who uses clay as a medium. My work deals primarily with my personal past. It is reflective of the past history of ceramic sculpture, and the work of a number contemporary sculptors. My monumental totemic masked figures express the culmination of past personal experiences, and deal more specifically with one date and event. The sculptures work universally as figures, and the viewer gains a sense of permanence from the pieces. My work related to African, Haniwa, and Egyptian sculpture. There is a sense of the culture of the people who made them, and a mysterious quality, …

Comparison Of Four Digital Halftone Screen (Dither) Patterns Using Quantitative Analysis Of The Binary Image Microstructure, Jacquelyn S. Ellinwood

Theses

The ordered-dither halftoning technique which reproduces continuous tones with spatially encoded binary imaging elements uses the digital halftone screen. The effect at the microstructural level of four screens on tone reproduction, spatial signal reproduction, and quantization noise is evaluated by measuring the tone reproduction curve (TRC), the two-dimensional Fourier transform of a constant density patch, the degree of harmonic distortion (THD), the system Modulation Transfer Function (MTF), and the Wiener Spectrum (WS) produced by each screen. The applicablity of these five conventional image evaluation metrics on binary output is also evaluated. Spatial averaging is done to convert the binary output …

An Investigation Of New Methods To Improve The Accuracy Of Modern Color Spectrophotometers, Kelvin H. Petersen

Theses

A study into the use of reflecting tiles to determine spectrophotometric errors and the corresponding correction values was accomplished. A method was developed to calculate the wavelength scale accuracy (out to a wavelength error of 5nm) using the inflection points of reflecting tiles' spectrophotometric curves. Using simulated error data, wavelength accuracy was determinable at seven distinct wavelengths over the range of 440 nm to 705 nm within an accuracy of 0.2 nm. Three methods, the Matrix, Selection, and Non-Linear, were developed to increase the accuracy of spectrophotometric data. Each method determined and corrected spectrophotometric data differently. The Matrix method was …

Real Time Maze Traversal, Robert Spina

Theses

This thesis investigates the application of artificial intelligence to real time control in combination with image analysis techniques. The system consists of a "mouse" and a "cheese" in a two dimensional maze which are viewed by a video camera connected to a frame grabber board in a personal computer (PC). The maze is designed to be alterable during the mouse's navigation towards the "cheese" or target. The pc runs the frame grabber software which analyzes the maze to find the cheese, mouse and movement options during traversal. Parameters about the mouse's position, the maze constraints in the vicinity of the …

A Microcomputer Based Non-Invasive Cardiopulmonary Monitor Using A Microwave Interferometer, Tanmoy K. Basu

Theses

With a microwave interferometer the vibrational velocity of the anterior (front), as well as posterior (back) chest wall can be monitored and recorded. The recorded signals are a reflection of the mechanical cardiac activity within the chest cavity, as opposed to Electrocardiogram (ECG) which is a reflection of the electrical cardiac activity. The interferometer recordings are obtained with no physical contact between the instrument and the subject. Moreover, the subject can be fully clothed since microwave energy readily passes through normal dry clothing.

A microwave interferometer that is capable of detecting the vibrational velocity of the surfaces of the chest …

Laser Perforation For Computer Paper, Claude F. Gattuso

Theses

In today's computer paper printing, cross and edge perforations are done only by mechanical perforators. The mechanical perforation process works fine since the width of the bridges and the length of the holes to be perforated remain large. Concerned with improvements in quality, printers have introduced microperforations. The holes and bridges of the perforation pattern are so small that after the user has torn off the sheet of computer paper along the perforation pattern, the edges of the document are very smooth and clean. Unfortunately, microperforations are reaching the limits of what can be achieved by the mechanical perforators. Because …

A Study Of The Effect Of Oil Added To Toray Driographic Ink On Toning In The Non-Image Areas Of Toray Company's Negative Working Driographic Plates, Joseph El-Yabroudi

Theses

Several studies and investigations have been conducted to test the new Toray plate. The studies revealed that the new plate eliminated many of the problems that used to hinder the progress and development of the driographic plate system. The two major problems with this plate were short run lengths and toning in the non-image areas. This study investigates toning problems in negative working Toray plates. Toning is a term that refers to the non-image areas of the driographic plate that are accepting ink. Previous studies have shown that ink tack and flow do not affect toning in any way. However, …

Pilot Study Of Hotel Ownership Patterns And Their Economic Impacts On Wales Economy, Joseph La Lopa

Theses

Countless cities, states and nations have decided to employ tourism development as a method to bolster their economy. One of the key components in a successful tourism development plan is the hotel sector. Hotel ownership patterns have a variety and range (from low to high) of economic impacts on the host community. Knowledge of the affects hotel ownership0 patterns have on the economy can serve to assist host governments in accomplishing specific economic objectives in their community. From this standpoint, it is entirely possible to facilitate a desirable outcome from tourist consumption of the host's cultural, historical and natural resources.

The Introduction, Demonstration And Evaluation Of A New Typeface Identification System, J. Ames Parsons

Theses

Graphic communicators, including typographers, designers, and descriptive bibliographers, are often called upon to identify typefaces. Since there are thousands of typefaces available in the marketplace today, it is unlikely that any one designer, typographer or bibliographer can name them all at sight. Accordingly, there is a need tfor a typeface identification system. The purpose of this paper is to introduce, demonstrate and evaluate such a system. An identification system called TYPE-ID was developed and tested. Two principles -- the "pass option" and the "null digit" -- were introduced. A sequence of questions was written for a number of different characters. …

The Application Of Neural Networks To Character Recognition Based On Primitive Feature Detection, Michael Pistacchio

Theses

This thesis investigates a character recognition method inspired by the premise that humans recognize shapes using their ability to assimilate a set of primitive features. These features collectively create a higher level shape of a certain category. The primitive features employed in our method include horizontal, vertical, diagonal lines, and corners of various orientations positioned at various places within a character. Combinations of these features form categories of characters to be recognized. The basic approach consists of preprocessing a character bitmap, extracting primitive features to form a feature vector. The feature vector is then input to a classification neural net. …

A Sql Front-End Semantic Data Model, Marc Richard Lodico

Theses

SQLSDM is a "front end" semantic data model to a SQL relational database management system (RDBMS). SQLSDM provides a more semantically complete RDBMS through the implementation of a Domain and Relational Integrity scheme. SQLSDM provides integrity definition functions and a sub-system to interpret SQL commands . Integrity system tables are created through the use of SQLSDM ' s domain definition command and SQL ' s "CREATE TABLE" command. As SQL database update commands are interpreted, SQLSDM uses these integrity tables to enforce domain and referential integrity. SQLSDM operates virtually transparent to the user and provides for greater database consistency and …

A Computer Implementation Of An Orthonormal Expansion Method For Digital Image Noise Suppression, Hui-Jung Lee

Theses

Images are usually corrupted by noise which comes from various sources: noise in the recording media (e.g. film grain noise), and noise introduced in the transmission channel. Noise degrades the visual quality of images and obscures the detail information in the images. One of the major sources of noise for images recorded on films is film grain noise. An orthonormal expansion algorithm for digital image noise suppression is implemented. The objective is to preserve as much sharpness and produce as few artifacts in the processed image as possible. The method sections an image into non-overlapping blocks. Each block is treated …

Parametric Splines In Tension, Surendra K. Gupta

Theses

A brief review of curve fitting terminology is presented, and the cubic spline interpolation scheme is outlined. Parametric and non-parametric curve fitting techniques are compared. The technique to fit parametric cubic splines is derived using the Euler- Lagrange formulation. Previous work on splines in tension is identified. Employing the notion of splines in tension, a method is proposed to fit a parametric curve to a set of (n + 1) points in ^-dimension space satisfying a specified set of boundary conditions. The curve fitted will not have any inflection points within any span and will be invariant with respect to …
