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 …

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

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 …

It was recommended by the committee that all school districts in Missouri adopt or adapt this method for evaluating the librarians in their schools. The purpose of this study was to determine how many school districts in St. Louis County evaluate librarians according to the Missouri Performance Based Evaluation for Librarians, and if not by this method, what methods …

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 …
