A Multipurpose Test Mask For Exposure Tool Characterization, Brian Benamati Jan 1987

A Multipurpose Test Mask For Exposure Tool Characterization, Brian Benamati

Theses

Of the many facets of integrated circuit fabrication, photolithography may very well be the most important due to the number of levels required for the fabrication of sophisticated devices. Therefore it is imperative to understand the performance capabilities of an exposure tool and identify its inherent limitations. Many methods have been developed which concentrate specifically on evaluating resolution, critical dimensions or registration. Often test patterns exist which vary widely for applications with respect to steppers, IX scanning projection aligners and other IX exposure equipment. The following work is focused on the requirements of evaluating and optimizing all aspects of performance …


A Comparative Study Of Four Major Knowledge Representation Techniques Used In Expert Systems With An Implementation In Prolog, Joann T. Hudgick Jan 1987

A Comparative Study Of Four Major Knowledge Representation Techniques Used In Expert Systems With An Implementation In Prolog, Joann T. Hudgick

Theses

Knowledge representation is a central issue in Artifical Intelligence (AI) research. In order to solve the diverse and complex problems encountered, one needs both a large amount of knowledge and some mechanism for the management and skillful utilization of that knowledge. The basic problem in knowledge representation is the development of an adequate formalism to represent that knowledge. In this thesis I will discuss four of the major techniques for representing knowledge in expert systems: first order logic, production rules, semantic networks, and frames. Using Prolog as the implementation language, I will demonstrate that all of the above mentioned representation …


Implementing Intersection Calculations Of The Ray Tracing Algorithm With Systolic Arrays, Andrea Stankus Jan 1987

Implementing Intersection Calculations Of The Ray Tracing Algorithm With Systolic Arrays, Andrea Stankus

Theses

Ray tracing is one technique that has been used to synthesize realistic images with a computer. Unfortunately, this technique, when implemented in software, is slow and expensive. The trend in computer graphics has been toward the use of special purpose hardware, to speed up the calculations, and, hence, the generation of the synthesized image. This paper describes the design and the operation of a systolic based architecture, tailored to speed up the intersection calculations, that must be performed as a part of the ray tracing algorithm.


Indirect Photometric Chromatography Of Iodide Ion In Aqueous Solutions, M. Liz Allyn Jan 1987

Indirect Photometric Chromatography Of Iodide Ion In Aqueous Solutions, M. Liz Allyn

Theses

Indirect photometric chromatography was applied to the detection and quantification of iodide ion in aqueous solutions. A Nucleosil SB column containing the trimethylamine functional group was utilized in this HPLC study to compare the selectivity and reproducibility of copper (II) nitrate, trimesic acid, and phthalic acid eluents. Trimesic acid eluent was the strongest eluent, R.(I~)=3.5min, followed by phthalic acid, R.(I~")=14.6min, and copper nitrate, R. (I~)=15.5min, assuming optimum conditions. Both aromatic eluents were held onto the column by adsorption reactions with the styrene-divinylbenzene matrix of the resin. Irreversible column damage was the result. Coupled with the fact that the copper nitrate …

A Study Of The Application Of Paper Spread Function Data To The Prediction Of Physical Dot Areas For Offset Lithography, Paul Lewis Dec 1986

A Study Of The Application Of Paper Spread Function Data To The Prediction Of Physical Dot Areas For Offset Lithography, Paul Lewis

Theses

This investigation was aimed at establishing a relationship between the optical spread function of four common printing stocks (cast coat, enamel gloss, enamel dull and ledger) and a Yule - Neilsen n value in predicting physical dot Area, for offset lithographic printing. Using an offset press each paper stock was printed with a test target containing common screen frequencies at percent dot areas from 5-90"/. and solid ink patches adjacent to each tint. Using planimetry and macrodensitometry, exact n values were calculated for comparison with the measured spread function of that same paper stock. No relationship between the optical spread …

A Cost And Performance Analysis Of The Three Electronic Communication Systems Currently In Use In The Printing And Publishing Industry, Susan Richards Dec 1986

A Cost And Performance Analysis Of The Three Electronic Communication Systems Currently In Use In The Printing And Publishing Industry, Susan Richards

Theses

This study describes and evaluates the three electronic graphic communication systems presently used by the printing and publishing industry. The author has selected generic system names for each of the systems. These are: System 1: Page Facsimile System 2: Character-Encoding System 3: Pixel Density-Map Page Facsimile systems are primarily used by newspaper publishers. The Character-Encoding and Pixel Density-Map systems are alternate methods primarily used by newsweekly magazine publishers. All three communication systems offer the user a means of transmitting editorial, and in some cases advertising pages, to remote printing facilities for manufacturing and distribution. Each electronic graphic communication system is …

An Exploration Of Triarylmethane Leucohydroxides, Mahin Sadrai Dec 1986

An Exploration Of Triarylmethane Leucohydroxides, Mahin Sadrai

Theses

To explore the possibilities of the potential use of photochromism of triarylmethane leucohydroxides and leucobisulfites , five leucohydroxides (see Table [5]) and five leucobisulfites were synthesized and two leucohydroxides and one leucobisulfite were investigated in a variety of solvents with different Brownstein Coefficients. Malachite green leucohydroxide and crystal violet leucohydroxide showed opposite behavior in the same basic solutions, while both of them were dramati cally affected by the change in solutions basicity. Photodegradation induced by repeated exposure (fatigue) manifested itself in the form of lower photo -induced optical density, with a constant halflife in malachite green leucohydroxide and in the …


Comparative Study Of Networks Using Packet And Circuit Switching Within A Single Network, Suman Sharma Nov 1986

Comparative Study Of Networks Using Packet And Circuit Switching Within A Single Network, Suman Sharma

Theses

During the last couple of years, in addition to voice, other types of communications network services are becoming increasingly important. These are interactive data, facsimile, slow scan image, and bulk data. Typically, these services are delivered by separate networks using various kinds of switching technology, such as packet, circuit, or message switching. Recently, much of the focus has been on the integration of all types of communication services within the same switch or network, especially within the telephony and business industry. Integration of the communication services is being realized by integrating packet and circuit switching within the same switch or …

A Detailed Measure Of Apparent Modulation Induced By Cornsweet Edges On A Digital Image Display System, Jeff Pelz Nov 1986

A Detailed Measure Of Apparent Modulation Induced By Cornsweet Edges On A Digital Image Display System, Jeff Pelz

Theses

A digital image display based system was designed and implemented to perform visual measurements of apparent modulation induced by the Cornsweet illusion. The system was used to examine the results reported on previous experiments designed to measure the modulation transfer function of the human visual system. The reported results of experiments performed by Dooley and Greenfield on induced modulation were examined, and data not reported in that work was collected on the range of modulations over which observers perceived linear images. The system developed has the flexibility to be adapted for many different types of experiments. Visual experiments involving human …


Image Motion Compensation For An Electronic Imaging System, James H. Cain Nov 1986

Image Motion Compensation For An Electronic Imaging System, James H. Cain

Theses

The design of an image compensation device is given which is capable of minimizing the in-track image disturbances caused by velocity variations in an optical scanning device. Guidelines for the development of this mechanism are based on known optical principles. Acceptable response capabilities for this device are based on subjective and quantitative image quality standards. A first order analysis of the device was conducted to specify the performance required to minimize the distortions mentioned above. The final system specifications take into account actual hardware that is currently available for the typical scanner system presented.
