A Study Of The Discernibility Of Electrophotostatic Copied Typestyles As Compared With Non-Electrophotostatic Copied Typefaces, Laura A. Melchionne
A Study Of The Discernibility Of Electrophotostatic Copied Typestyles As Compared With Non-Electrophotostatic Copied Typefaces, Laura A. Melchionne
Theses
This paper reports the results of an investigation into the discernibility of seven typefaces when overlayed by 15 different gauges brought into contact with each type face. Discernibility was tested under two conditions; standard (original typeset words) and electrophotostatically copied (second generation copies of the original typeset words) . The question that this investigation was attempting to answer was whether or not certain typefaces are more discernible after electrophotostatic copying than other typefaces. The seven typefaces were chosen because they have a known aesthetic preference that can be catergorized in three groups; most preferred, inbetween and least pre ferred. Preference …
The Computer As A Tool In The Ethical Development Of Primary School Children, Nancy B. Landau
The Computer As A Tool In The Ethical Development Of Primary School Children, Nancy B. Landau
Theses
When I first thought about my thesis topic at the end of last year, I had a very different concept from what eventually developed into this project. My original intention, that of using the computer as an educational tool in the ethical and social development of primary school children, has remained the same. The changes occurred in my methods of achieving this intention. My rationale for promoting the computer as an educational resource is manifold. For example, the world that these children will be entering as adults will be entirely computerized and automated. This next generation must have more than …

Characterization Of Ion Implanted Antimony, Michael J. Cumbo
Theses
Ion implanted antimony (121Sb) is characterized as an n-type dopant in single crystal (100) oriented silicon. The required implantation equipment and critical parameters are discussed. The experimental procedures used in this study are presented along with the resulting data on dopant distribution and crystal damage annealing. The tradeoffs between antimony and arsenic, the more commonly used heavy n-type dopant, are examined from both a process end a device perspective. The context of this comparison is in applications that require a heavily doped layer beneath a thin deposit of epitaxial silicon. Results of a specific buried layer process characterization are included.

A Performance Comparison Between A Wide-Hinged Endpaper Construction And The Library Binding Institute Standard Endpaper Construction, Claudia Chaback
Theses
For the last fifty years , library binders have employed a standard endpaper construction for all of its bindings. Now, because of new binding techniques and the deterioration of paper some preservationists have placed a demand on library binders to develop an alternate endpaper construction. The purpose of this study was to determine the hinge strength and openability performance of the two most conmon library binding techniques, oversewing and Singer side sewing, which were flat backed and rounded/backed in relation to the currently used the LBI Standard endpaper as compared to the wide-hinged endpaper construction. It was questioned if there …
An Investigation Of The Performance Of Gray-Component Replacement, Melissa Berry Tolmie
An Investigation Of The Performance Of Gray-Component Replacement, Melissa Berry Tolmie
Theses
Members of the graphic arts industries are slowly becoming aware of undercolor reduction techniques used in the attempt to help stabilize high speed wet printing. Undercolor removal is a color correction method which follows this line of thought as it reduces the amount of ink coverage by the process-color inks and increases ink coverage of the black printer in the darker neutral areas of a reproduction. The advantages realized by this technique are carried even further with gray-component replacement (GCR) . GCR removes the process color inks that make up a dark tone and replaces them with black ink in …
A Study Of Toray's Negative Working Driographic Printing Plate And The Effect Ink Tack Has On Toning In The Non-Image Area, Larry M. Capitano
A Study Of Toray's Negative Working Driographic Printing Plate And The Effect Ink Tack Has On Toning In The Non-Image Area, Larry M. Capitano
Theses
Driography is a planographic printing process. A driographic printing plate differs from a conventional offset lithographic plate in that water is not required to keep the non-image area clean of ink during printing. Water, or fountain solution, is not required during printing because a silicone rubber coating which repels ink is used for the non-image area of a driographic plate. The first driographic plate was introduced in the early 1970's by the 3M Company. The plate was a positive working printing plate and has since been discontinued. Driography has since been researched by a number of companies but only one …

Thermal Degradation Of Polymer Blends Containing The Poly(Hydryoxy Ether Of Bisphenol-A), Joseph S. Formosa
Theses
The thermal degradation of blends of phenoxy with polycaprolactone , poly ( 1 , 4-butylene adipate), poly(l,4-cyclohexane-dimethylene succinate), poly( 2 , 2-dimethyl-l , 3-propylene succinate), and poly( hexamethylene sebacate) has been studied using thermogravimetric analysis, direct-pyrolysis mass spectrometry, and infrared spectroscopy. For each blend, the polyester componenent was less thermally stable in the blend compared to the pure state. The thermal stability of the phenoxy was not affected by the presence of the polyesters in the blends. Blends of phenoxy with polycaprolactone and with poly ( 1 , 4-butylene adipate) degrade in two-step mechanisms where the amount of weight loss …
Automated Segmentation Of Urban Features From Landsat Thematic Mapper Imagery For Use In Pseudoinvariant Feature Temporal Image Normalization, Carl Salvaggio
Automated Segmentation Of Urban Features From Landsat Thematic Mapper Imagery For Use In Pseudoinvariant Feature Temporal Image Normalization, Carl Salvaggio
Theses
An automated segmentation algorithm for the isolation of pseudoinvariant features was developed. This algorithm utilizes rate-of-change information from the thresholding process previously associated with the pseudoinvariant feature normalization technique. This algorithm was combined with the normalization technique and applied to the six reflective bands of the Landsat Thematic Mapper for both urban and rural imagery. The segmentation algorithm and normalization technique were also applied to color infrared high resolution U2 imagery. The accuracy and precision of the normalization results were evaluated. The technique consistently produced normalization results with errors of approximately one or two reflectance units for both the rural …

A New Imaging Material Utilizing Exposure Induced Free Radical Reduction Of Stabilized Soluble Metal Salts, Patrick Friedman
A New Imaging Material Utilizing Exposure Induced Free Radical Reduction Of Stabilized Soluble Metal Salts, Patrick Friedman
Theses
A new non-silver halide imaging material is proposed. The light sensitive element within the material generates free radicals upon exposure, through a fragmentation process. The free radicals, which can be generated imagewise, are then used as a catalyst to promote the reduction of an image forming element. The image forming element is a stabilized, soluble, metal salt which is chelated rendering it unaccessible for reduction by the atmosphere. The film matrix is virtually grain-free as is the final image, with some dependence on the binder and amplification process employed.

A Study Of The Brain's Transfer Function For Edge Perception, Charles G. Fink
A Study Of The Brain's Transfer Function For Edge Perception, Charles G. Fink
Theses
A concept was developed and a computer program was designed and implemented to model the eye, the brain, and the perception system. These models were used to study edge transformation through the human visual system. The eye model was developed using optical spread and neural sampling data along with different inhibition distributions. The effects of lateral inhibition on retinal edge response were studied and hypothetical brain transfer functions were calculated. The results of this study indicate that no single mechanism or linear model can explain both the sinewave response and edge perception for the human visual system. The eye and …

The Effect Of Solid Ink Density On Shifts In Hue In Gray Component Replacement, Hans P. Kellogg
Theses
With advances in computer storage and electronic dot generation scanners a new color separation process has become possible. Although in theory the Gray Component Replacement (GCR) process has been possible since the early twenties, it has only recently been available through contemporary color separation methods. GCR is the process by which the gray component of a particular color reproduction is removed from the reproduction and replaced with black ink. The gray component is defined as specific combinations of the least predominant color and the other remaining inks. A printing form was designed to include three different color reproduction processes: the …
