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

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 …

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

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 …

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 Finite Element Solution Of Thermal Wave Propagation In Elastic Media, Dominic N. Dalo

Theses

The rational theory of thermodynamics is used to develop equations governing the propagation of thermal waves. A new vector quantity is introduced to account for the thermal waves. The phenomenon of thermal wave propagation is illustrated by considering the problem of one-dimensional heat conduction in a finite slab subjected to a heat flux pulse. The solution is obtained via the finite element method. A discussion of the results and their significance is also presented.

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 …

Stylistic Analysis And Recognition Of Piano Sonatas Of Four Composers -- Mozart, Chopin, Debussy, Anton Webern, Emily Feng-Hwa Lin-Jeng

Theses

This thesis describes a system that incorporates techniques developed by musicologists to do stylistic analysis of music, an important applied field in music theory analysis. To do the analysis requires the knowledge of many musicological analysis methods and pattern recognition algorithms that are central issues to this project. In addition, AI techniques of learning were used to improve the whole system's skills. The conclusions reached as a result of this project were that computers can perform musical tasks usually associated exclusively with naturally intelligent musicologists, and that learning techniques can expand and enrich the behavior of musically intelligent systems.

Partitioning And Protecting Control Program Function Through Virtual Storage, Thomas J. Murray

Theses

Many operating systems are endowed with the ability to access every byte of addressable memory in the processor complex. Unfortunately, a control program so designed creates an exposure of the following nature: It is possible for an errant section of operating system code to unwittingly modify (and perhaps destroy) either its own storage or the storage of others. This thesis addresses this problem and discusses the design and implementation of a control program in which many such attempts at destroying storage are detected and suppressed. This is accomplished by placing separate control program functions in separate virtual storages. The thesis …

The Effect Of S-Donor Ligands On The Sensation Of Silver Bromide Crystals With Iridium (Iii), Juan A. Zuleta

Theses

Different concentrations of potassium thiocyanate (SCN) were used in combination with Iridium (III) hexachloride (Ir) to surface sensitize an octahedral silver bromide emulsion. Surface sensitivity increased by 0.90 log H over the unsensitized emulsion when Ir and SCN were added during sensitization compared to 0.45 log H when the iridium salt was used alone. A decrease of 2.40 log H was observed when an Ir-SCN complex was formed and then added to the emulsion. An increase of 1.05 log H was obtained if gold, thiocyanate and iridium were used. Similar results were obtained using tetramethylthiourea (TMT) or thiodiglycol (TG) instead …
