The Design And Production Of Graininess Samples Using An Ordered Array Binary Imaging System, Paul W. Jones

Theses

A technique is described for producing graininess samples using an ordered array binary imaging device with subsequent photographic and lithographic steps. Such samples could be combined to form a visual scale for use in the rapid assessment of solid area noise of electrophotographic images. The potential advantages of this process include high volume production capabilities and the ease of varying image parameters over a wide range. Analytical models for mean density and Wiener spectrum scale value, WS(0), are developed for the ordered array system and are shown to have general applicability. However, these models are neither precise nor accurate enough …

Theoretical Determination Of Optimum Split-Filter Exposures For Color-Correction Masks, Jang-Fun Chen

Theses

Workers have found that a split-filter mask made by consecutive exposures through red, green, and blue filters provides better color correction than a mask exposed through a single filter. Nevertheless, split-filter masking has never been adopted in the direct screen separation method. This may be due to the difficulty of determining the opti mum red: green: blue split-filter exposures. This thesis ad dresses the problem of determining the optimum split-filter ratios needed to expose masks for the direct screen sepa ration method. Optimum exposure ratios were determined with the as sistance of a digital computer by systematically trying out 231 …

Nicaragua: A Society In Transition, James Mason Stillings

Theses

Between December 1980 and March 1981, I spent three months in Nicaragua undertaking a documentary thesis project for a Master of Fine Arts degree in Photography. Initial preparation for the trip began in May 1980. My thesis exhibition was held October 11-16, 1981. The purpose of the thesis was to "integrate creative expression with social/political concerns by photographing aspects of societal change that have grown out of the popular revolution in Nicaragua." This report is an accounting of that project from its inception to its completion. The project has been a rewarding experience, full of learning and growth. I have …

Proposal And Investigation Of A Method For Measuring Process Color Variation Via Reflection Densitometer, Russell Harris

Theses

This thesis proposes a method of using reflection density readings taken with a conventional graphic arts densitometer to provide a numeric measure of the visual difference between a sample press sheet and a reference sheet. This numerical measure was developed based on the theory that human response to variation in process color printing is more affected by changes in the proportions of process inks to each other than by variation in the overall inking level of the press sheet. The thesis then goes on to explain how the proposed system was tested. First, a set of color samples was generated. …

Reactions Of Nitrogen Dioxide With Chloride And Bromide Salts, Thomas Allston

Theses

Infrared absorption spectroscopy was used to study the reaction of nitrogen dioxide with a number of halide salts: MX (s) + 2N02 (g), XNO (g) + MN03 (s), where M = metal and X = halogen (CI, Br). This reaction was observed for the chloride and bromide salts of sodium, potassium, calcium and magnesium. These reactions do not reach thermodynamic equilibrium, and evidence is presented that they are surface controlled. These reactions are very fast and evidence is reported for the relative rates of the chloride and bromide salts. The following mechanism may explain the observed experimental results: (M+X-)(s) + …

Leachate Treatment Technique Utilizing Fly Ash As A Low Cost Sorbent, Turan A. Ramadan

Theses

This study was carried out to design a system for the inexpensive treatment of ash pond effluent or leachate. Twelve different coals were burned in three different types of coal fired boilers to determine the influence of coal composition, ash fusion temperatures, boiler additives, combustion conditions and co-firing of natural gas or oil with the coal, on the composition of the fly ash and bottom ash as well as the leaching and sorbate characteristics of the fly ash produced.

Prediction Of Cut-Off Frequency From The Maximum Slope Of A Transmittance Scan Of An Ideal Edge, Dale E. Ewbank

Theses

This study has empirically shown that the maximum slope of an ideal edge scan in transmittance versus position is an excellent indicator of the cut-off frequency at which a microdensitometer system's modulation transfer function goes to zero. It was found that numerical aperture of collection objective, scanning slit width and alignment, system focus, and sampling interval are parameters which must be carefully chosen and set-up when implementing or using this slope technique to check system performance.

Generation Of Software To Produce A Landsat Scene Comprised Only Of Pseudo Invariant Features, Martha C. Leahy

Theses

The purpose of this thesis work was to provide soft ware in Fortran programming language that will read, print and process data contained on Landsat computer compatible tapes. The programming was done on the Xerox Sigma 9 computer at the Rochester Institute of Technology. The processing involved reading and re-registering fractions of files and performing simple numeric operations on the digital spectral radiance values of individual picture elements. The result was a fraction of a Landsat scene containing pixels that are classified as vegetation, water, mixed elements or invariant features.

Bedouin Textiles Of Saudi Arabia, Celia Wright

Theses

During the past year I have had the opportunity of working closely with a collection of Saudi Arabian woven textiles and other crafts. These textiles are characterized by the combination of a great variety of techniques, indicating a diffusion of techniques between the Arabian Peninsula and adjacent cultures. The frequent combination of both warp-faced and weft-faced structures within a single woven piece is particularly fascinating, as it rarely occurs in other cultures. This thesis will research the techniques and designs used in Saudi weaving and in the weaving of adjacent and related cultures in Africa and the Middle East which …

The Printing Industry In Sub-Sahara Africa: An Exploratory Study, H. Richard Harmsen

Theses

The printing industry in Sub-Sahara Africa faces numerous problems inhibiting further growth and development. Because of a scarcity of published information regarding these problems, and regarding the nature of the industry in general, this study hoped to establish a beginning and baseline for researchers, printing managers, suppliers, development planners, and anyone else interested in the development of the African printing industry. Specifically, the objectives of this study were to identify: 1) the general characteristics of the printing industry in Sub-Sahara Africa; and 2) the primary constraints inhibiting its further growth and development. Information was gathered by several means, including a …

The Effect Of Ink/Fountain Solution Emulsion Of Paper Permanence, Thomas H. Spotts

Theses

The permanence of printed documents and books appears to be primarily dependent on paper stability. Other researchers implicate pH as a major factor in the deterioration rate of paper and acidity as major the cause of this deterioration. During the lithographic printing process, ink is in direct contact with fountain solution, which can be acidic or alkaline. Fountain solution is a mixture of water and chemicals used to keep the non-image areas of a lithographic plate moist. On press the intimate contact of ink with fountain solution creates a fountain solution-in-ink emulsion. The emulsion used here is a stable suspension …

Teacher Judgment, Teacher Rating And Reading Readiness As Predictors Of First Grade Reading Achievement, Linda White

Theses

This study concentrates on the efficiency of three predictive measures used at the end of kindergarten to predict how kindergarten students will perform in reading in relation to three ability groupings of high, average, or low for first grade. Through research this writer attempted to find out if a teacher's own prediction for future academic achievement in reading will be as efficient as a prediction of a rating scale or a reading readiness test.

Included in this paper the researcher has a review of the problem of prediction in education and a review of the factors that researchers have considered …
