Natural Shelters, Habitable Landscapes, Joseph Vitone

Theses

The purpose of this thesis will be to try to share with you an energy and character that I find in trees, in the earth, in the qualities of light, in the intimacy of houses and yards. There is a simple yet deep-running link between our created spaces (our homes) and the spirit and body of the woods. I feel a strong kinship between myself and the land that produced me- -a super-blood tie, a joining from long ago--that transcends anthropocentric thought and concern. I want to know that link, to be at ease with the earth and to extend …

Determining Spectral Sensitivity Of Kodak Micro Positive Resist 820, Matthew L. Huck

Theses

The spectral sensitivity of KODAK Micro Positive Resist 820 has been determined for the spectral range of 300nm to 500nm. A xenon-source monochrometer was used in a hard contact exposing system. Se/isitivity is defined as the inverse of the exposure (mj/cm ) needed to produce an image in a photoresist coated plate having walls of 70 normal slope. Low intensity reciprocity law failure has been conclusively shown to exist in this resist with exposure intensities of 100 mw/cm and below. Guide lines have been drawn up, based on the procedures and results of the experimentation, to assist photoresist users in …

The Effects Of Agitation In Positive Photoresist Image Quality When Using A Bubble Development System, Keith D. Mogerley

Theses

An important goal of the microelectronics industry is to make new technological advances while keeping the cost of the fabrication process down. To achieve this goal, the microelectronics industry are presently placing more active devices on each chip, while at the same time trying to increase the number of successful chips per wafer. In order for the industry to successfully do this, they must reduce all of the dimensions in the circuit while trying to maintain its physical, chemical, and functional properties. These demands have made all steps of the fabrication process more critical. The scope of this project will …

A Decision Theory Approach To Tone Reproduction, Kevin E. Spaulding

Theses

The concepts of statistical decision theory were applied to the photographic tone reproduction system to develop an objective measurement of tone reproduction accuracy called the "expected loss" of the system. Reproductions were made of four scenes using systems with a wide range of tone reproduction characteristics. The expected loss for each system/scene combination was calculated, and the perceived tone reproduction accuracy was determined using the psychophysical scaling method of magnitude estimation. A statistically significant correlation was found between the subjectively determined accuracy, and system expected loss, but the degree of correlation was not high enough for the merit function to …

The Effect Of Microscope Scale Reticle Design On Variance Of Measurement, David D. Rockafellow

Theses

Little work has been documented regarding the design of optical instrument scale reticles. Reticle is the word used to describe both scales and crosshairs used in the eyepiece of an optical instrument. An ergonomic (the relation of man to his working environment) experiment was performed in which thirteen different scale reticles were designed, manufactured and tested. The design parameters tested were scale spacing, line height, and line thickness. The testing consisted of thirty observers measuring a circular test object through a microscope with each scale reticles. The results, taking into consideration both variance in measurement and observer comments, showed the …

Industrial Art Materials, Frank S. Defrancis

Theses

Anyone, who has ever tried to paint has become well acquainted with the fact that huge sums of money too often buy the meagerest amounts of supplies.

Deregulation Of The Telecommunications Industry And The Bell System Divestiture - Impact On The Universal Service Concept, Edward H. Hancock

Theses

The Communications Act of 1934 established the principle that our nation' s future telecommunications policy was to be structured on the concept of "Universal Service", i.e. that telephone service is essential, and as such , should be made available and affordable for all . Deregulation of the telecornmunications industry and the soon to be accomplished Bell System divestiture will have a significant adverse impact on the universal service concept. The rationale for this premise is presented as follows . First, a theoretical analysis is made of the changes in the regulated utility revenue requirement which will result from deregulation and …

The Effect Of Developer Composition On Adjacency Effects In Black And White Photography: Metol Vsl Phenidone, Paul L. Zengerle

Theses

Increased chemical adjacency effects in black and white photography can be obtained using certain Metol and Phenidone developers. Four different effects are described: 1) development inhibition by iodide ion 2) development inhibition by bromide ion 3) exhaustion of Metol 4) development inhibition by oxidized Phenidone Edge effects produced by Metol exhaustion and by Phenidone development are enhanced by moderate increases in pH. They are reduced by: the addition of hydroquinone, high levels of sodium sulfite, and high fog levels. Developers designed to increase adjacency effects also increase granularity. The trade-off betv/een acutance and granularity is approximately linear for the film-developer …

Bending Vibrations Of A Cantilever Beam On An Eccentric Rotating Disc, Yousry S. Aboelnaga

Theses

The differential equation of motion for the C.G. line of a vibrating cantilever beam which is mounted on an eccentric rotating disc is derived. Exact solutions in terms of hypergeometric functions of this fourth order differential equation with variable coefficients are obtained by making several mild assumptions. These solutions include a large class of vibrational modes.

The primary idea leading to the exact solutions is the factorization of the fourth order differential operator into a pair of commuting second order operators.

Moment Method Solution Of The Time-Dependent Transport Equation To Describe The Scattering Of Gaussian Plane Wave Pulses By A Forest, Nack Yang Cho

Theses

The time dependent transport equation is used to study the transmission of periodic pulses through a forest. The forest is assumed to occupy a half-space region, to be statistically homogeneous and to scatter energy isotropically A periodic sequence of Gaussian plane wave pulses is assumed to enter the forest normally from free space. The transport equation is solved by the moment method using triangular expansion functions. Numerical results indicate the dependence of the incoherent intensity on penetration depth, observation angle, albedo and pulse repetition rate.

On The Analysis And Design Of Clamped Rectangular Plate With Partial Load, Yacin Saaid Jaboury

Theses

In this Thesis, maximum deflection and bending moments of a partially loaded clamped rectangular plate are studied. The loading is uniformly applied to a retangular area proportional to the shape.

Navier's Solutions on partially loaded simply supported rectangular plate is superimposed with edge moments to give the clamped boundry condition.

Solutions of maximum deflection and bending moments are derived in Double Series form. A Fortran program is employed in obtaining the numerical results. When the partially loaded area approaches zero it becomes a centrally loaded case; and when loading area to plate area ratio approaches unity it becomes a uniformly …

Flow Tube Reactions Of Selected Chlorocarbons With Molecular Hydrogen Or Water Vapor In A Microwave Induced Plasma Reactor, Robert Benedict Barat

Theses

The reactions of various chlorinated hydrocarbons with molecular hydrogen or water vapor have been studied in a microwave plasma tubular flow reactor. The investigation of such reactions is desirable because the often toxic parent chlorocarbons are transformed to more thermodynamically stable and relatively non-toxic products by removal of' chlorine atoms as hydrogen chloride. Present detoxification technologies generally employ thermal oxidation as a means of disposal of chlorocarbons, which does not offer a thermodynamically stable sink for the chlorine atoms.

The experimental apparatus included feed introduction systems, a microwave plasma reactor, and full product analyses. The feed systems enabled use of …

Commemorative Pottery, Jo Brenner

Theses

The clay forms for my thesis commemorate personal experiences, dreams, memories, and fantasies. I view my work as capturing a moment of something familiar; a reminder of ordinary events that might have gone unnoticed. The unity of imagery, surface and form is the major investigation for my thesis. Drawing from autobiographical themes and searching for an equilibrium between figure and vessel are the criteria from which I work. I also explore the process of transfor mation of my images from two dimensional figures to their full three dimensional expression.
