Effect Of Errors In Spectrophotometry Due To Fluorescence On The Ability To Calculate Colors By The Neugebauer Equations, Junichi Iwao

Theses

Spectrophotometers were originally designed without taking into account the fluorescent effect of papers and inks on spectrophotometric measurements. Monochromatic illumination is used in most of the available spectrophotometers, but the spectrophotometric curve measured by using monochromatic light does not approximate the same effect that is seen by the eye if fluorescence is present. White light illumination must be used to obtain a valid spectrophotometric curve of fluorescent materials. The Neugebauer equations are often used to calculate the tristimulus values of halftone prints. As long as the Neugebauer primaries do not fluoresce, measurements of primaries made by monochromatic illumination are valid. …

The Use Of Thin Layer Chromatography (Tlc) In Qualitative And Quantitative Determinations Of Photographic Developing Agents (In Developer Solution) Using A Scanning Densitometer, Michael Gilbert

Theses

TLC was used, for qualitative and quantitative analysis of photographic developing agents hydroquinone, metol, phenidone, para phenylenediamine, para aminophenol, ascorbic acid and the oxidized species. Experimental conditions and procedures for reporting Rf values of the aqueous solutions of the developing agent were standardized. Quantitative TLC was done for hydroquinone. The density maxima obtained from the scanning densitometric trace of the eluted and visualized chromatogram was correlated to the concentration of the hydroquinone. Aqueous solutions of hydroquinone were prepared at four levels of concentration, three levels of pH and two levels of sodium sulfite concentration for quantitative analysis using TLC.

A Photographic Study Of Movement Of Material On A Web Offset Press Blanket, Leigh Stewart

Theses

This paper studies the movement of material which accumulates on the image printing blanket of a web offset press printing newsprint. A theory is advanced to explain this movement. It is based on the differences in velocities of the paper and blanket surfaces entering and exiting the printing nip. The designed experiment run uses three factors to test the changes in direction and rate of movement. These are: (1) the compressibility of blanket sets, (2) the relative image printing and impression blanket diameters, and (3) the printing squeeze. No other factors involved in the nip area are tested. The movement …

A Dead Time Process Controller, Frank Hermance

Theses

The control of systems containing pure dead time elements has plagued the control engineer for many years. This thesis discusses a new controller developed by this writer which offers improved performance in first order processes dominated by a dead time element.

Resolving Power Determination By Direct Observation Of Unprocessed Film By Reflected Light, James Belisle, Emery Prather

Theses

Measurement of resolving power of an emulsion is usually determined by an extensive exposure and development series. Resolving power is reported at the optimum value and exposure and density are reported also. Such a procedure is wasteful and time consuming. This paper explores the determination of resolving power by the observation of a reflected image of a resolution target on unprocessed. The reflection from the gelatin support was higher than that of the silver halide grains and thereby masked the reflected image from the grains. This phenomenon was observed over the entire range tested. The maximum obtained was 746 lines …

The Objective Evaluation Of Image Quality Produced With Physical Development, Bruce C. Smith, Keith M. Snyder

Theses

This experiment was an analysis of the difference in objective measures of image quality between chemical and physical development methods, including prefixation and postfixation processes. Of particular interest was the process outlined by Matejec1 for postfixation physical development. An investigation of resolving power and MTF for two fine grain films was carried out for four different development processes all possessing approximately the same speed capability. Both the effect of combined chemical and optical spread functions and the chemical spread alone were investigated through edge analysis using Fourier methods. A significant increase in image quality was found with the finest grain …

A Method Of Determining Dot Sharpness Of Lithographic Films, Timmy Mccreary

Theses

Two methods were attempted to determine an objective evaluation of lithographic films with respect to the sharpness of half-tone dots produced by the films. In Method I a step function target was placed in contact with a continuous wedge and a film sample. After exposure and development, a curve of the film was drawn in terms of per cent transmission versus log exposure. Since the input (target) is a step function, the output (curve) should also be a step function. It was expected that the width of the step in the curve would yield some measure of how well the …

Fast Fourier Transform With Computer Program, James Chapin

Theses

Many computer programs have been developed to calculate the Fast Fourier Transform (FFT). It is the intention of this thesis to develop the tree graph idea, presented by E. 0. Brigham and R. E. Morrow in the article "The fast Fourier transform," into another computer program that will calculate both the forward and inverse Fourier transforms using nonsymmetrical periodic functions. Most of the information obtained was from periodicals with relatively little available in text books. General matrix equations and calculations presented in proofs were developed by this thesis. The tree graph idea was also expanded to a general form. First …

The Chemistry Of Azides, Edward D. Nelson

Theses

A review of the decomposition of alkyl and aryl azides by thermolysis and photolysis has been accomplished. Organic azides are a very distinct species that undergo its own unique reactions. Azides decompose to form an electron deficient nitrogen having a sextet of elcctrons. This is called a Nitrene. Nitrenes can exist in the singlet or triplet state. The triplet behaves like a diradical. General and specific reactions of nitrenes have been shown with detailed mechanisms accounting for the products. The main modes of nitrene stabilization are rearrangement, hydrogen abstraction and insertion. Insertion is characteristic of singlet species and abstraction characteristic …

Insulation Coordination On A 115 Kv System Addition To The Rochester Gas And Electric Corporation System, Clifton Olson

Theses

The Transient Network Analyzer is used to determine the maximum magnitude and duration of transient and sustained overvoltages which can occur on a system during any change of state. Where a change of state may be the energization or deenergization of a line by operating a circuit breaker, the occurrence of a fault condition or a sudden loss of load. These overvoltages are then used to establish equipment needs and duties, design alternatives which meet these requirements and establish acceptable operating procedures. With these established, the transient voltage magnitudes are then used to establish the transmission line Basic Insulation Level …

Siegmund Lubin: Moving Picture Pioneer 1851-1923, John Arthur Helley

Theses

Siegmund Lubin came to the United States of America in 1867, and six years later, after various setbacks, established an optical business in Philadelphia, Pennsylvania. Experiments in his leisure time led him to a career in moving pictures. His success and accomplishments in the period of two decades were entangled in legal battles which resulted in his return to the optical business.

Mr. Lubin built several studios across the United States in a westward expansion. His studio in Coronado, California in 1915–16, with eastern controls, proved to have been typical of the western studio during the early motion picture days. …

Relationship Of Preferred Tone Reproduction To Picture Size, David Miller

Theses

A relationship between preferred tone reproduction and final picture size is suggested in many forms in the literature and in practical experience. This project uses photographic halftone prints varying in tone reproduction and produced at different sizes to investigate this relationship. The tone reproduction variations are introduced electronically using an RCA color scanner and a method of eigenvector analysis is used to reduce these tone reproductions down to their important components. The final set of prints consisting of ten tone reproductions, three reproduced sizes, and two sharpnesses are evaluated to determine their subjective quality in the judgement of a group …
