A System For The Generation Of Tonal Music Based On Transformations, Karl J. Myers

Theses

Most if not all of the approaches being used in the computer study of natural languages also have been applied to the computer study of music. Music theorist Heinrich Schenker (1867 - 1935) developed a system for the study of tonal music that is compatible with the transformational grammars defined by linguist Noam Chomsky for the study of natural languages. Steven Smoliar ( 1980 ) defined transformations, based on Schenker’s theory, for the analysis of musical compositions. This study provides background into the application of grammars in the generation of musical compositions and a full implementation of the transformations defined …

Implementation Of An Activity Coordinator For An Activity-Based Distributed System, Robert Shaw

Theses

Distributed computing systems offer a number of potential benefits, including: - improved fault-tolerance and reliability - increased processor availability - faster response time - flexibility of system configuration - effective management of geographically distributed resources - integration of special purpose machines into applications In order to realize this potential, support systems that aid in the development of distributed programs are needed. An Activity System facilitates the design and implementation of distributed programs: (1) By allowing the programmer to group functionally related objects into an activity (or job) which is recorded within the system. The information stored concerning relationships between objects …

A Simulator For The Intel 8086 Microprocessor, William A. Chapman

Theses

This project was originally suggested by J. Schueckler as an aid to teaching students the Intel 8086 Assembly Language. The need for such a tool becomes apparent when one considers the expense of providing students with dedicated hardware that rapidly becomes obsolete, but a Simulator which could be easily updated and runs on a general purpose or timesharing computer system would be accessible to many students for a fraction of the cost. The intended use of the Simulator therefore dictated that it precisely model the hardware, be available on a multiuser system and run as efficiently as possible. An additional …

Application Of Computer Techniques In Groundwater Contamination Studies, Komratchi Raman

Theses

A study has been undertaken to provide insight into two related aspects of groundwater contamination studies - contaminant transport behavior and its analysis by modeling techniques. The study reviews recent research that explains some of the uncertainties in the transport and fate of chemical contaminants in groundwater. Approaches to modeling techniques and data reduction are developed to illustrate their usefulness in analysing existing groundwater data, and to make predictions on the future water chemical characteristics. Three types of study areas have been chosen for this purpose, each representing a different type of groundwater contamination problem. The first study area has …

Comparison Of Color Lightness In Two-Color Plus Black Reproduction Systems Vs. Three-Color Reproduction Systems, Lonnie Jackson

Theses

A theory that has existed since 1948 has just recently gained wide acceptance from the printing industry. The recent technological advancements in electronic scanners has made it feasible for color separations to be scanned implementing Gray Component Replacement (GCR) . Eventhough most of the electronic scanners today have GCR capabilities, some questions regarding GCR and its implementation have gone unanswered. In an attempt to help resolve this problem, this paper investigated the issue of lightness characteristics associated with GCR reproductions. In particular, this paper attempted to prove that, by replacing a graying component of a conventional reproduction made up of …

Design And Implementation Of A Local Area Network Utilizing Intel 310/80286 Systems, James Leach

Theses

The goal of this work was to provide the foundation for a course in networking by developing the hardware and software for a token ring Local Area Network (LAN). Any course work in networking would focus on the emerging International Standards Organization (ISO) Open Systems Interconnections (OSI) model. This model provides a seven layered structure, where each layer performs some logical aspect of the communication process. Thus, the software developed would have to provide the functionality of a multiple layered design, implying multiple tasks communicating by operating system primitives. Also, a simplified design would minimize the time for those students …

A Mathematical Analysis Of An Electronic Dot Generating Scanner For Dot Resolution And Tone Reproduction, Frederick K. Waechter

Theses

An electronic dot generating scanner is a complex machine. This complexity is based in the photographic methods which the scanner is designed to duplicate. This study addresses the mathematical principles of the entire scanner system. This paper was intended to provide an improved understanding of the scanner system. The hypothesis states that a mathematical analysis with experimental verification can be developed to accurately model the internal optics, tone reproduction, and output dot characteristics of an electronic dot generating scanner. The analysis begins with a functional block diagram, which shows the information flow through the scanner. This diagram breaks the process …

Thermal Degradation Of Polymer Blends Containing Poly(Vinyl Chloride), David W. Lee

Theses

The thermal degradation of blends of poly(vinyl chloride) ( PVC ) with poly(vinyl acetate) (PVA), and two ethylene-vinyl acetate copolymers containing 70 weight percent vinyl-acetate (EVA70) and 45 weight percent vinyl acetate (EVA45) were studied by thermogravimetric analysis and direct-pyrolysis mass spectrometry. The PVC, PVA, EVA45 and EVA70 degrade in two-step processes for each polymer. The PVA/PVC , EVA45/PVC and the EVA70/PVC blends do show some inter action during the first step of the degradation process while the respective second steps are unaffected. The acid produced by the degradation of one polymer causes accelerated loss of the other acid in …

Evaluation Of Word Processing Cost Effectiveness, Nicholas E. Tedesco

Theses

The objective of this thesis is to examine the use of word processing technology to determine if its implementation is a cost effective investment. This will be accomplished by comparing the cost of a typewritten page before and after the implementation or upgrade of word processing equipment. The degree of utilization and the impact of utilization on standard costs will also be examined.

Significant difficulty was encountered attempting to locate and compile statistical information on word processing. Therefore, a questionnaire was developed and distributed to the 100 largest public and 100 largest private companies headquartered in New Jersey, requesting information …

Factors Influencing The Rate Of Sensitization And Maximum Sensitivity Of An Iridium (Iii) Surface Sensitized Silver Bromide Emulsion, Nimrod Natan

Theses

A monodisperse silver bromide emulsion was surface sensitized with potassium hexachloroiridate (III). The rate of sensitization and maximum photographic sensitivity were determined at different sensitization conditions. The effects of silver ion concentration (pAg), length of sensitization, and the presence of the thiocyanate onion during sensitization were defined. The highest gain of sensitivity of an Iridium sensitized emulsion over an unsensltized emulsion was 0.43 log H units at pAg 9 after 30 minutes of after-ripening at 70 C. The highest gain of sensitivity of an iridium + thiocyanate sensitized emulsion over an unsensltized emulsion was 0.55 log H units at pAg …

Land Cover Classification Of Landsat Thematic Mapper Images Using Pseudo Invariant Feature Normalization Applied To Change Detection, Tim Hawes

Theses

A radiometric normalization technique for compensating illumination and atmospheric differences between multi-temporal images should allow classification of the images with a single classification algorithm. This allows a simpler approach to land cover change detection. Land cover classification of Landsat Thematic Mapper Imagery with and without Pseudo Invariant Feature Normalization was performed to demonstrate the effect on classification and change detection accuracy. A post-classification change detection method using two separate classification algorithms, one for each date, was performed as a baseline comparison. Land cover classification using one classification algorithm was attempted with and without gain and offset correction to serve as …

An Analysis Of Wet-On-Wet Trapping Using The Walker And Fetsko Ink Transfer Equation, Sam Powell

Theses

In this thesis the Walker and Fetsko ink transfer equation was used as an analytic tool to determine how the physical properties of the transfer surface change from printing on unprinted paper to overprinting on another wet ink film. The equation has three parameters, b, k, and f, which indicate what is happening in the nip of the press during the moment of impression. Parameter b represents the maximum absorptive capacity of the paper, parameter k is highly reflective of printing smoothness, and parameter f represents the fraction of free ink film which splits to the paper surface. The I.G.T. …

Deuterium Isotope Effects On In Vitro Dealkylation Of 1,1-Dimethylhydrazine And 1,1-Dimethylnitrosamine Via Hepatic Enzymes, Robert Sloane

Theses

Boiling 1,1-dimethylnitrosamine or unsymmetrical dimethylnitrosamine several times with 25% NaOD in D2O promoted the complete exchange of the nitrosamine’s alpha protons for deuterium. The deuterated nitrosamine was reduced by LiAlH4, in anhydrous diethyl ether to the corresponding 1,1-dimethylhydrazine-d6. An in-process production of the oxalate salt was necessary due to the air sensitivity of the free base hydrazine. After recrystallization from absolute ethanol and extensive drying, the oxalate salt was evaluated for purity by mixed melting point, high performance liquid chromatography and thin layer chromatography. When protonated hydrazine-oxalate salt (mp=146 °C) was mixed with a sample of the exchanged hydrazine salt …

Comparison Of The Mid-Frequency Line Edge Noise Algorithms Of Jim Hamerly And Yigal Gur For The Best Correlation To The Psychophysical Defect Known As Raggedness, Kevin Huff

Theses

A study was conducted to compare the mid-frequency line edge noise algorithms of Jim Hamerly and Yigal Gur. Comparisons were made to determine which algorithm correlated best with the psychophysical defect known as raggedness. Tests were conducted on "standard" observers using a series of test images with varying amounts of edge noise. A master image was produced photographically and ensuing images generated with random error using electrophotographic processes. Scanning of the images to determine output metric values was done on a Zeiss microdensitometer. It was found that with electrophotographic prints, the Hamerly algorithm has a correlation coefficient of .83. Determination …

Database Recovery, Kim L. Emanuel

Theses

Recovery techniques are an important aspect of database systems. They are essential to ensure that data integrity is maintained after any type of failure occurs. The recovery mechanism must be designed so that the availability and performance of the system are not unacceptably impacted by the recovery algorithms running during normal execution. On the other hand, enough information must be stored so that the database can be restored or transactions backed out in a reasonable amount of time. Concepts, techniques, and problems associated with database recovery will be presented in this thesis. The recovery issues for both centralized and distributed …

A Study Of Color Image Quality With Respect To Screen Angle Arrangement In Multicolor Halftone Printing, Ted (Te-Chung) Chen

Theses

The advantage of using a single screen-angle (Dot-on-Dot) reproduction for multicolor halftone printing is a sharper reproduction with the decrease, of. a rosette pattern in all image areas. The purpose of this study was to quantify the differences of color image quality between conventional reproduction using four screen-angles and a single screen-angle printing technique. In addition, the influence of screen frequency to the final color image quality in the Dot-on-Dot printing was also investigated. The results of this study confirmed that there is a linearity of image quality for all color halftone printing regardless of the arrangement of the screen …

Awakening The Spirit, Jane Emily Dalton

Theses

I have chosen to create a series of woven rugs and handwoven panels which reflect a personal vision. I choose to think metaphysically about the world I live in and about the objects that surround me. Life represents a spiritual journey in which each of us is involved. The Bible says that, "Many are called, but few are chosen." However, I tend to agree more with the following statement: "We all are called and we are all chosen if we simply have the courage to step into the unknown." Many things could cause a person to begin an internal evaluation …
