Protective Laboratory Measures For The Flexible Wall Permeameter And The Atterberg Limits Tests Using Hazardous And Toxic Chemicals, Robert A. Tetla

Theses

Safety procedures for performing geotechnical testing with hazardous and toxic materials, excluding radioactive wastes, are developed for the Flexible Wall Permeameter and the Atterberg Limits Tests. The tests were evaluated in detail to determine the critical points at which the technician would be exposed to the hazardous and/or toxic permeant. It was found that the following safety measures should always be taken; 1) the apparatus and all testing should be undertaken in a sliding sash hood using the proper face velocity, 2) air monitoring using a personal dosimeter and/or a detector tube is required to assure that the concentration of …

Changes In Corporate Culture And Management Training Programs Resulting From The Divestiture Of At&T, Lisa Karen Fenster

Theses

The affects of divestiture upon the American Telephone and Telegraph Company are studied with particular emphasis upon changes in corporate culture, structure, goals and objectives, and management training programs.

A case study approach utilizes a literature search and interviews of a limited number of AT&T executives. It is confirmed that directly or indirectly, management training directions at AT&T are a reflection of corporate goals and objectives, and in a general sense, the corporate culture.

The relationship between training and the corporate culture is not direct and immediate but rather general and evolving. The corporate culture itself is seen as a …

Digital Fm-Demodulation Using Digital Signal Processing Techniques, Peter Wagner

Theses

This thesis presents the results of research in the area of digital demodulation of FM signals. The first part of the thesis describes the performance of digital Hilbert-transformers and Differentiators that are optimized in a determined bandwidth. These digital filters are used to build a digital Klapper-Kratt detector. According to this procedure, the coefficients of the digital Klapper-Kratt detectors up to the filter length N=25 are calculated and the resulting discriminator ripple computed and evaluated. One suggested algorithm gives the opportunity to balance the detector at a certain center-frequency. The major part of this thesis describes a new approach towards …

Human Factors In The Design Of Computer Graphics Input/Output Interfaces, Michael Uche Amadi

Theses

Computers are used for solving problems of various kinds and therefore, if the users are to fully benefit from the systems, they must be considered during the earliest stages of the system development. There are three major classes of computer users namely: naive, managerial, and scientific-technical. These users have different characteristics that the designer must consider within his/her system. Only by including such distinctions will these user groups each be able to perform at their respective optimum levels. Just as there are different users, there are also numerous applications to which computers can be applied. This thesis will be restricted …

The Effects On Hue Resulting From Black Overprinting In Halftone Reproductions, Brian Philippsen

Theses

A type of black printer that only existed in theory is now being applied in the printing industry. The process which makes use of this black printer is known as gray-component replacement. Developed from the extension of the undercolor removal process, the use of gray-component replacement in printing halftone reproductions is said to result in numerous technical and cost benefits. When used to the maximum, the process eliminates one of the three process color inks in a given unit area and prints black ink from highlight to shadow. A problem can result from the use of this process as it …

An Analysis Of Stroke Fluid Flow In A Converging Channel Using A Penalty Function Finite Element Formulation, Keith A. Honkala

Theses

A penalty function finite element program is developed to study two dimensional creeping flow in a converging channel. The finite element solution is compared to the analytical solution of purely radial flow. The analysis reveals that the assumption of purely radial flow is valid for small apex angles, but is inappropriate for larger angles .

Determining Process Latitude With Electrically Measurable Test Structures, Jonathan Littlehale

Theses

Collection of linewidth data is an important part of photoresist characterization. Linewidth data are usually collected by optical measurements or scanning electron microscopy. Both of these techniques are tedious and time-consuming. In this work, electrically measurable test structures are used to collect linewidth data. These structures use a measured sheet resistance, a known length of conducting material, and the measured resistance of the structure to determine the linewidth. The benefits of using these structures include completely automated data collection and the ability to collect statistically significant amounts of data. This allows the use of existing statistical analysis software to analyze …

The Use Of Edge Gradient Analysis On Chrome And Emulsion Photomasks To Determine Modulation Transfer Functions, Marcy E. Levin

Theses

Using edge gradient analysis on chrome and emulsion photomasks to determine the modulation transfer function of a mask making system proved to be limited by the method in which the edge gradients were observed. Scanning electron micrographs were taken of the chrome and emulsion edges on various masks, and results showed that chrome photosmasks exhibit steeper gradients and better edge acuity than emulsion images. However, due to the ratio of line size to gradient size on each of the types of masks, it was decided that the gradient would not make a significant contribution to modulation loss in the image.

The Effect Of Cross-Coupling On The Temporal Response Of Ultrasonic Transducer Arrays, David Hadley

Theses

An investigation was performed examining a possible cause of acoustic cross-coupling in ultrasonic transducer arrays. It was postulated that pulse velocity was decreased due to the physical presence of other ultrasonic pulses in the medium. It was demonstrated that average pulse velocity is independent of the number of opposing waves traveling through an acoustic medium. A description of variable pulse velocity is discussed.

Spectrophotometric Color Formulation Based On Two-Constant Kubelka-Munk Theory, Eric Walowit

Theses

A new approach to computer color formulation based on non-linear least-squares techniques has been developed to characterize colorants and predict their behavior in mixtures. This approach allows the optimization of absorption and scattering calculations to characterize these colorants. This same method has been used to directly match the spectral reflectance of a standard with a mixture of colorants that yields nearly the same spectral reflectance as the standard being matched. Several advantages have been gained over more traditional methods: Kubelka-Munk K and S has been determined without primary binary blends, the spectral reflectance of the standard and proposed formulation exhibit …

The Effects Of Early School Entrance On Standardized Test Performance, Janet Prior

Theses

This study was designed to investigate whether early school entrance affected the level of standardized test performance as a child progressed through school.

It was hypothesized that students' standardized test scores would correlate significantly with the age at which they entered school, that the standardized test scores of early-entrants would be significantly lower than middle-entrants and late-entrants, that standardized test scores of middle-entrants would be significantly lower than those of late-entrants, and that there would be a significant difference between the standardized test scores of girls and boys whose chronological ages were similar at the time they began attending school. …

A Study To Eliminate Moire Patterns Produced In Color Separations When Scanning Polachrome Cs Transparency Film On The Hell Dc-300 B/L Laser Scanner, Edwin Parker Price

Theses

The Polaroid Corporation, in May of 1983, introduced Polachrome CS color transparency film and a new process called the Autoprocess system. This system offers the convenience of obtaining instant color transparencies in about three minutes. The film has excellent projection and viewing characteristics. The product was designed to have its largest market with professional photographers. Polachrome's construction creates problems for the printer in that moire patterns occur during the separation process. This study gives a short background for both additive color screen films and dye layer films, and a comparison is made to help the reader understand the problems with …

The Fabrication And Testing Of A Lead Iodide Photovoltaic Cell, Keith Greenberg

Theses

A new type of photovoltaic cell using lead iodide as the photosensitive element and aluminum and silver as electrodes was constructed and then tested for open circuit voltage, monochromatic quantum yield of short circuit current, and fill factor. A similar cell was also fabricated using the familiar merocyanine dye M-8 as the photosensitive element for use in a control experiment. Minimal open circuit voltages of not more than 26 mV were obtained for lead iodide while much larger photovoltaic parameters were obtained for M-8. The poor and impermanent performance of lead iodide relative to the organic control suggests that lead …

A Comparison Of Training Available To Entry Level Naval And Merchant Marine Engineroom Personnel, Paul J. Bugelski

Theses

Similarities between occupations or industrial environments are often overshadowed by differences between goals, services, or products. From the time that shipboard steam propulsion became a practicality the Naval and merchant marine services have experienced this phenomena. For various reasons, the two sectors have ignored similarities between their respective occupational sub-groups, e.g. engineroom crews, and the training which facilitates each group's performance.

Manning and training problems, related to the evolution of automated shipboard propulsion plants, have been shared by the U.S. Navy and commercial ship operators. Recent events such as the British Falkland Islands crisis and the implementation of the U.S. …

A Diagnostic Study Of Burning Black Powder Via Stroboscopic Laser Schlieren Photography, Donald Bruce Rowland

Theses

The combustion processes and products of a single grain of burning black powder were experimentally investigated via the stroboscopic laser schlieren photographic technique. A high power modulated argon laser system was used in conjunction with a streak camera to provide a dynamic sequence of time resolved, high resolution schlieren photographs of a burning black powder grain. When black powder burns, a multi-phase product is produced consisting of hot gases, solid particles, and a molten liquid spray. The expansion processes of this multi-phase product cloud were recorded and characterized. Molten drops, reactive and nonreactive particles within as well as outside of …

Reflections From A Soul Of Glass, Mills Lyon

Theses

I have long had a "love-affair" with photography. As a teacher of photography and a "semi-professional" photographer, I desired to further my study of photography by seeking a master's degree in this field. In so doing, I have had many opportunities to examine my feelings toward this subject and my relationship with it.

The purpose of this paper is to explore both my technical and aesthetic relationships with photography. In examining these two areas, I have also looked at my photographic past as well as the photographic involvement in my present way of living.

In Chapter One I examine what …

Reflection Upon The Intangible Process Of Professional Development In A Graduate Program In Counseling Psychology, Judy Iris Fletcher, Mary Randa Kapp

Theses

The following narrative is a personal account of the experiences, observations, and awarenesses of two students completing their Masters degrees in counseling psychology. It represents an effort to document what we view as an identifiable and stress-producing process of growth occurring within an academic framework. We feel that this duality of personal growth and professional development is inadequately addressed in graduate programs. Yet, we have found this unstated, underlying, and inevitable threat of uncertainty, risk, and change to be as predictable a reality as the theoretical coursework required.

This paper is written not so much to prove a point as …
