The Use Of The Spline Function In Computer-Aided Type Design, Kathleen Barry Albertini

Theses

The traditional type designer works with pen, in and paper. The characters that he designs go through many changes before the whole font is finalized and set in the printing medium. Further alterations to the font may occur after he prints and evaluates a sample piece of text. Computer-aided type design presents the type designer with a new design tool. Computers have been used in the printing industry for typesetting; the automation of type design is a logical next step. Freeing the designer from the repetitive tasks of the design cycle is one obvious advantage cf using computers. But computer-aided …

Three Dimensional Resonant Vibrations And Stresses In Turbine Blade Groups, Patrick J. Kline

Theses

This thesis describes an efficient procedure for calculating three dimensional resonant vibrations and stresses in intermediate and high pressure turbine blade groups. This procedure is capable of calculating all the natural frequencies, mode shapes, and bending stresses in the tangential, axial, and coupled modes of vibration. Simple beam theory is applied to develop a dynamic stiffness matrix. The solutions to this matrix give the natural frequencies and mode shapes for the blade group. Prohl's energy method is used to determine the amplitude of the forced vibrations and the dynamic stresses. A Goodman diagram fatigue criterion is applied to evaluate the …

A New Correlation For Heat Transfer During Flow Boiling, Bhabesh K. Thakur

Theses

This thesis is concerned with an investigation carried out to establish a new correlation for the prediction of the heat transfer coefficient during flow boiling through tubes, vertical and horizontal flows, for water and organic fluids (including refrigerants). An additive mechanism of convective and boiling heat transfer has been formulated to give the net heat transfer during flow boiling. The correlation employs three dimensionless parameters: the Convection number, the Boiling number and the Froude number. The correlation has been tested with the data (over 500) from twelve experimental cases of six investigators and the mean deviation from the measured values …

Laboratory Experiences In Listening Comprehension For English As A Second Language Program, Sima Mokhtari

Theses

This study is undertaken in an attempt to help teachers to consider listening comprehension as a skill which is different from pronunciation, reading, and writing. Comprehending the second language is one of the most difficult tasks for the language learner and it is the most neglected skill in second language teaching. This neglect sterns from our ignorance about the nature of the process of listening comprehension, and from the lack of our knowledge about techniques on what and how to teach students to comprehend the spoken language.

The listening comprehension skills are separate from pronunciation and grammar. This paper presents …

The Effect Of Screen Ruling On The Saturation Of Pastel Gamut Colors, John T. Chittick

Theses

Reproduction of pastel colors by offset lithography produces images that have less color saturation than their continuous tone counterparts. This problem is primarily attributable to the halftone structure which approximates continuous tone pastels with large amounts of white paper and small amounts of chromatic ink. This thesis investigates the effect of screen frequency upon pastel color saturation. Single and two color overprint tints of nominal five, 10, and 15 percent printing dot areas were printed in 85, 100, 120, 133, 150, and 200 lines screen rulings. The reflectances of these colors were measured with a colorimeter and converted to CIEL*a*b* …

Granularity: Investigating Equations That Convert (T) To (D), Frederick Catt

Theses

An investigation was done on three published expanded equations, that convert (T) to (D). T. Celio, J. Altman and M. Abouelata published equations of the same form, but with differing constants. Their equations were derived by using an assumed square-wave transmittance trace. The investigation was to find the best predictor of (D) from (T) . Both practical and simulation tests were run. The density range was extended, to check for failure at both high and low densities. Standard granularity measurement procedures were followed as close as possible. Results, from the practical tests, showed Altman 's equation the best predictor of …

Osmotic And Mean Activity Coefficients Of Libr And Lic In Methanol At 25, 35, And 45 Degrees C, Peggy Tomasula

Theses

Vapor pressure depression data of LiBr and LiCl in methanol at temperatures of 25,35, and 45°C were measured in the molality range 0.1-4.4m using a static method, where the difference in vapor pressure of the electrolytic solution is compared to that of pure methanol.

Osmotic coefficients were calculated from the vapor pressure data. This data was then correlated with both the one parameter Bromley equation and the three parameter Pitzer equation. For all systems at all temperatures, the data were better correlated by the Pitzer equation than with the Bromley equation. Mean activity coefficients of the two salts at the …

Kinetics Of Rehalogenation Bleaches, Kenneth A. Harrison

Theses

A study was made to determine if a correlation existed between the silver density at 318 nm and the actual amount of silver present in photographic film. Based on twenty (20) samples of bleached and unbleached film, a linear correlation was found, for specific film/ developer combinations, with a correlation coefficient in excess of 0.99. The above correlation was then used to evaluate the bleaching kinetics of several rehalogenation type bleaches. It was postulated that there is a charge barrier effect between the photographic gelatin and the positively charged oxidizing agent in the bleaches. This was caused by the pH …

An Investigation Of A Matching Lexical Cloze Procedure With Eighth Grade Students, Elaine S. Bewig

Theses

In order to systematize the item writing procedure for developing reading comprehension measures for the regular classroom, the major purpose of this study was to compare the reliability, validity, and difficulty of a matching lexical cloze test, two traditional or passage-question group informal reading tests, and a standardized measure of reading comprehension, the Stanford Achievement Test. One of the traditional group informals was composed of two reading sections, each followed by 20- 25 literal comprehension questions which were developed by Finn in his dissertation of 1973. The other traditional group informal was composed of two reading selections taken from a …

Treatment Of The Second Degree Athletic Ankle Sprain, Michael P. Pratte

The Effect Of Development Temperature On Kodak Pr 10 Instant Print Product Using A Comparative System Modulation Transfer Function For Analysis, Jon E. Van Tassell

Theses

The effects of temperature of development upon the final image quality of Kodak PR lOr were investigated. Image quality was defined as a Modulation Transfer Function obtained using a Square Wave Log Periodic target for quantitative analysis. Analysis of Variance tables were used to separate experimental error from actual temperature related variability. With a confidence level of 99% the temperature of development was found to affect the Modulation Transfer Function of this product. With temperatures below 48 degrees the effect was greater than with temperatures above 78 degrees but not greater than 90 degrees. Also documented was a decrease in …

Spatial Frequency Processing In The Human Visual System: A Study Of Black Versus White, Robert Seyfert

Theses

The human visual system responses to resolution targets whose small area spatial content has been altered from white to black has been investigated. Modified tri-bar targets were presented to observers on a rear projection screen at constant average luminance and varying levels of contrast. Each observer was asked to determine if he could see the target and if the target had been modified. Responses indicate that there is no difference in the visibility of targets in which small areas have been changed to white or black but whose spatial frequency content is the same.

Light Scattering In Unprocessed Photographic Emulsions, Jo S. Kirkenaer

Theses

A method is proposed to measure scattering characteristics of non-processed photographic emulsions without using expensive or complicated computer processing techniques. A photo goniometer was assembled from a standard spectrometer, a lightsource and a photodiode. Film samples were measured both in air and in an index matching liquid comparing samples of two main categories, continuous tone pictorial emulsions and graphic arts copyfilms. It was learned that the measurements separated the samples into the above mentioned categories based on response variables such as scattergram and its corresponding Fourier Transform. This method is proposed as a tool in emulsion design engineering or quality …

The Effect Of Emulsion Stabilizers On The Rate Of Solution Of Silver Halide Grains, Christopher L. Dumont

Theses

The effects of the emulsion stabilizers, 4-hydroxy- 6-methyl-l ,33a,7-tetraazaindene and l-phenyl-2-tetrazoline- 5-thione on the rate of solution-physical development of a monodisperse AgBr emulsion containing Carey-Lea silver sol were measured at a series of concentrations. A study of the effects of the silver halide solvent, sulfite has been stud ied along with a low-solvent surface developer. It was found that the tetraazaindene definitely had an effect on the rate of solution-physical development, while the l-phenyl-2- tetrazoline- 5-thione did not have a significant effect.
