Second Order Coherent Power Spectra, Brian A. Gorin Aug 1983

Second Order Coherent Power Spectra, Brian A. Gorin

Theses

The relationship between second order stochastic processes and coherent power spectra are explored for developed grain size frequency distributions of silver halide emulsion/developer combinations. Although Wiener spectra represent incoherent power spectra, the coherent case has been unresolved due to the difficulty of filtering the optical system effect. The emulsion plates were exposed with a uniform irradiance distribution from an incoherent tungsten source to create a series of uniform density samples. Conventional processing chemistry is utilized with substitution of different developer types, from predominantly physical development to direct chemical development. The exposed and processed density samples were liquid gated with refractive …


A Constant Force Bicycle Transmission, Thomas Chase Aug 1983

A Constant Force Bicycle Transmission, Thomas Chase

Theses

A prototype design for a human powered automatic transmission intended for use on an ordinary touring bicycle is presented. The transmission is intended to automatically adjust the gearing of the bicycle to maintain an optimum pedal force, regardless of the current riding conditions. Therefore, the transmission eliminates the need for the cyclist to manually adjust the bicycle gearing. The entire transmission is a self-contained unit designed to bolt onto the rear wheel of an otherwise unmodified 27-inch bicycle. The transmission combines a unique adaptation of a commercially popular continuously variable traction drive with a totally mechanical integral feedback controller. The …


A Software Prototype For The Ibm Series/1 Remote Intelligent Printers, Thomas Weber Jul 1983

A Software Prototype For The Ibm Series/1 Remote Intelligent Printers, Thomas Weber

Theses

Over the period of December 1982 to May 1983, a software prototype to support the IBM 4975 model 01 A printer was developed. The host computer was the IBM Series/1 minicomputer. The printer controller used was the Feature Programmable Multi-Line Adapter. Both the controller and printer contain one or more microprocessors that do some processing for the Series/1. With the RS232C electrical interface, the printer has remote capabilities. The electrical interface performs data transmission that is serial, asynchronous, and full duplex. This thesis serves as an application showing how intelligent printers and controllers can be utilized effectively on the Series/1.

Technology In The Late Twentieth Century: Humanism Versus Technocracy, A Philosophical Inquiry, Peter Moss Handler Jun 1983

Technology In The Late Twentieth Century: Humanism Versus Technocracy, A Philosophical Inquiry, Peter Moss Handler

Theses

As an artist in metal living and working in the last part of the twentieth century, I feel it to be important that my work relate to this specific period of time. That is, to look where we are going becomes more important than where we have been. The most powerful single influence on where we are going, in my judgment, is technology. The images of technology, not the things of it, become my starting place. My intent, however, is not merely to celebrate technology. That is an uncritical attitude.

Anagenesis: Rebirth Of A School Into A Residential Facility, Susan Michel May 1983

Anagenesis: Rebirth Of A School Into A Residential Facility, Susan Michel

Theses

Although it may appear that this thesis represents a narrowly defined project with respect to the building, the type of resident and the time in which it is occupied, in reality, its associations go in two directions. The thesis reaches back to historical and intellectual precedents, while at the same time lays a fertile ground for related work in the future. The following documents establish the goals and organization of the thesis and in doing so, become the introduction.


A Limited Comparison Of Ultraviolet Curing And Convection Drying On Paper Permanence, Nancy Bittner May 1983

A Limited Comparison Of Ultraviolet Curing And Convection Drying On Paper Permanence, Nancy Bittner

Theses

Archivists, conservators and librarians are concerned with paper permanence. Tests have shown that paper permanence is affected by light (especially ultra violet), temperature and humidity changes, acidity, in sects and rodents, and by general use. Environmental damages are often insidious. The objective of this study is to find whether ultraviolet curing and evaporative drying as experienced in the printing industry would affect paper permanence. Glen G. Gray's procedure for finding the reaction rate (the rate at which chemical reactions are completed) of paper is followed. This method relies on the fact that a chemical reaction occurs at speeds which depend …


An Application Of Multi-Dimensional Scaling To The Re-Examination Of Preferred Tone Reproduction, David J. Porter May 1983

An Application Of Multi-Dimensional Scaling To The Re-Examination Of Preferred Tone Reproduction, David J. Porter

Theses

Black and white prints were produced of several scenes that varied in both negative contrast and negative exposure. Subjects rated the various prints by categories based on their own personal understanding of what an excellent print was. The boundaries of the categories were found and used to determine the preferred tone reproduction characteristics. Individual differences were also scaled with the use of a proximity measure determined from the categorical data. The preferred contrast (1.46 +0.24) was significantly higher than the contrast that has been found to be preferred in earlier studies. The application of this study to more general situations …

Micro-Circuit Reticle Fabrication: An Investigation Of A Silver Halide Emulsion As A Portable Conformable Mask, Patrick St. Cin Apr 1983

Micro-Circuit Reticle Fabrication: An Investigation Of A Silver Halide Emulsion As A Portable Conformable Mask, Patrick St. Cin

Theses

An investigation of the possibility of spin-coating a silver halide emusion similar to that used on Kodak HRP plates onto a positive resist coating reticle blank was made. By changing the cating weight and temperature of the emulsion it was found that the emulsion could be coated onto the reticle without harm to the positive resist material. A five micron width line was imaged successfully and measured in the final chrome sub-layer of the reticle.

A Decision Theory Approach To Tone Reproduction, Kevin E. Spaulding Apr 1983

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 …


Derivation Of The Transformation Relationship Of Pseudo-Invariant Features Of Two Landsat Images, Jeffrey R. Sefl Apr 1983

Derivation Of The Transformation Relationship Of Pseudo-Invariant Features Of Two Landsat Images, Jeffrey R. Sefl

Theses

The purpose of this effort was to determine the relationships of the spectral radiance distributions of pseudo-invariant features for a selected pair of Landsat images. The relationships for the four bands (band 4 through band 7) were determined to be linearly related. The transformation equations will map one images brightness values on to a second images brightness values.


Determining Spectral Sensitivity Of Kodak Micro Positive Resist 820, Matthew L. Huck Apr 1983

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 Effect Of Microscope Scale Reticle Design On Variance Of Measurement, David D. Rockafellow Apr 1983

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 Apr 1983

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. Faced with the possibility of either breaking into art supply stores at night or learning to vent my hostilities elsewhere I traded my studio supplies for their industrial counterparts and gratefully have never looked back. The following report will document the advantages as well as the disadvantages that I have encountered in working exclusively with industrial art materials. The first half will deal the materials themselves while the second half will offer a …
