Digitization, Testing, And Evaluation Of A Device For Rapid Determination Of Rms Granularity, Daniel J. Williams

Theses

A rotary stage microdensitometer was interfaced to an Apple II personal computer for the purpose of making rapid rms granularity measurements. An experimentally determined relationship was found between standard deviation in voltage and rms granularity. By using this relationship the device proved accurate to within 7 percent of the known values of rms granularity on a conventional microdensitometer for the same samples with 95 percent confidence.

Nicaragua: A Society In Transition, James Mason Stillings

Theses

Between December 1980 and March 1981, I spent three months in Nicaragua undertaking a documentary thesis project for a Master of Fine Arts degree in Photography.

Pattern Generation And Fault Detection In Digital Circuits Using A Microprocessor, Syed Riffat Ali

Theses

The main object of this Professional Project was to establish a microcomputer based system which could detect faults in digital circuits. Hardware and software for the Motorola 6800 microcomputer system was fully developed. Node level diagnostic programs were then used to pump known "Bit Patterns" into digital circuits and responses recorded via Pseudorandom binary sequence generator using CRC code. This method also known as "Signature Analysis" was then applied to detect faults successfully in Universal Asynchronous Receiver Transmitter or UART Circuits.

Investigation Of Mental Workload In A Visual Inspection Task, Michel Alfandari

Theses

This thesis consists of an investigation of the "mental workload" involved in a visual inspection task. A short-term laboratory experiment was conducted on twenty test subjects to study the effects of three typical job-related factors encountered in mental workload situations: load stress, time stress, and motivation. These effects were assessed through the subjects' performances as measured by speed and accuracy data. The analysis of the results revealed that an increase in load stress deteriorates both speed and accuracy, whereas time stress improves speed but only at the expense of accuracy. The expected positive influence of motivational factor (cash prizes) was …

Prediction Of Heats Of Mixing By Group Contribution Methods, William Walter Rupp

Theses

Three group contribution methods used to predict heats of mixing were tested: AGSM, UNIFAC with temperature dependent parameters and the modified UNIFAC of Skjold-Jor-gensen et al. The modified UNIFAC provided the best results and was adopted in this study. Primary parameters were obtained for ten groups with alkanes. The simultaneous correlation of cyclic and straight-chain alkanes gave poor results. Attempts to improve the error by changing the group area parameter for cyclic CH₂ failed.

A major problem in correlating the experimental data was the multiplicity of roots. The best set of parameters was obtained by using a grid approach …

Opinions Of Hollenbeck Junior High Students Regarding The Year-Round Schedule, Teri Timmons

Theses

This study, conducted by Teri Timmons in partial fulfillment of a Master of Arts in Education degree at The Lindenwood Colleges (1982), explores the opinions of junior high students at Hollenbeck Junior High School in the Francis Howell School District regarding Year-Round Schooling (YRS) versus the Traditional School Schedule (TSS). Amid growing interest in alternative academic calendars due to rising student populations and limited funding for new educational facilities, this research sought to evaluate student attitudes toward these two scheduling models.

A random sample of 35 students who had experienced both YRS and TSS during their elementary years was surveyed …

An Investigation And Implementation Of Recommendation X.25 On A Motorola M6800 Based Network, Louis Nyerges

Theses

A subset of the Recommendation X.25 protocol is implemented on a two node network. Each node accepts and translates data from the user in a sequential fashion into the appropriate protocol structure for transmission to another node. Each node has the capability of full duplex operation. The hardware is built around a Motorola M6800 microprocessor employing a minimum of 4096 words of random access memory and two asynchronous ports: one for communication with the user and the other for communication with the network. The software on each node contains the protocol programs and a multitasking monitor which is used to …

A Comparison Of The Perception Of Juxtaposed Tones In Newspaper Images When Screened With Conventional And Random Dot Screens, Sylvia Monteiro

Theses

The halftone process has been the conventional means of reproducing photographic artwork on newsprint. The use of relatively coarse screen rulings, dictated by the paper characteristics, produces an image with a noticeable dot pattern. Furthermore, the printing process is susceptible to extreme dot gain variation, which affects tone reproduction and the pictorial communication of the image. There were good reasons to suspect that a random dot screen could give more consistent tone rendition than a conventional halftone screen. A comparative study of the consistency of perception of conventional and randomly screened images when printed on newsprint has not yet been …

The Stability Of Reciprocity Law Failure In Color Print Papers, Victoria L. Carriero

Theses

A study of reciprocity law failure in Kodak Ektacolor 74 and 78 color print papers was carried out by a series of equal engery exposures. Using a color separating filter pack to differentiate the response of RLF of the individual emulsion layers an acceptable color print is attainable by using these curves to determine exposure and filtration changes.

Development Of A Quantitative Spectrophotometric Assay For Lectins, Kim E. Goppert

Theses

A new quantitative spectrophotometric assay for lectins has been developed. It involves mixing a copolymer with a lectin solution and measuring the absorbance change as a function of time as the resulting solution becomes turbid. The slope obtained could be correlated quantitatively with the amount of lectin present. The assay has sensitivity problems at low lectin concentrations and also a reproducibility problem. More study is required in these two areas.
