Numerical Analysis Of One-Dimensional Waves In Generalized Thermoelasticity, Mark J. Gorman
Numerical Analysis Of One-Dimensional Waves In Generalized Thermoelasticity, Mark J. Gorman
Theses
Classical thermoelasticity theory is based on Fourier's Law of heat conduction, which, when combined with the other fundamental field equations, leads to coupled hyperbolic-parabolic governing equations. These equations imply that thermal effects are to be felt instantaneously, far away from the external thermomechanieal load. Therefore, this theory admits infinite speeds of propagation of thermoelastic disturbances. This paradox becomes especially evident in problems involving very short time intervals, or high rates. of heat flux. Since infinite wave speeds are physically unrealistic in some situations, and since experiments have shown the existence of wavetype thermoelastic interactions, like in the observation of thermal …

Reliability Analysis Of Triple Modular Redundancy System With Spare, Khalid A. Al-Kofahi
Reliability Analysis Of Triple Modular Redundancy System With Spare, Khalid A. Al-Kofahi
Theses
Hardware redundant fault-tolerant systems and the different design approaches are discussed. The reliability analysis of fault-tolerant systems is usually done under permanent fault conditions. With statistical data suggesting that up to 90% of system failures are caused by intermittent faults, the reliability analysis of fault-tolerant systems must concentrate more on this class of faults. In this work, a reconfigurable Triple Modular Redundancy (TMR) with spare system that differentiates between permanent and intermittent faults has been built. The reconfiguration process of this system depends on both the current status of its modules and their history. Based on this, a different approach …

Diamonds In The Rough: A Journey Of Human Spirituality, Holly Lynn Hoover
Theses
The purpose of my thesis was to express various aspects of human spirituality using sculpture as the vehicle for this expression. During the course of my exploration clay and glass each came to take on special metaphorical significance and it became crucial to include both materials within the sculptures. I wanted to create a "marriage of materials" wherein the clay and glass needed each other to make a complete statement. Various clay surfaces and glass processes were explored and will be described later.
Docutech Open Job Submode Simulation, Lisa Bickerstaff
Docutech Open Job Submode Simulation, Lisa Bickerstaff
Theses
What does computer-based training (CBT) have in common with art? Artists have always striven to produce artwork under various constraints and conditions. Trying something new was considered a rebellion and artists were often criticized. Through the ages, artists have had to overcome many obstacles, including exploring the limitations presented by their chosen media. Building a visual interface for a computer in the past was left to the programmer. At the time this was acceptable, because only a programmer would look at it. Today, almost everybody uses a computer and appealing graphics are a must. The programmer from the past cannot …

The introduction of the computer drastically changed the nature of the graphics arts industry, and in watching the rapidly changing technology, I realized that these new developments broadened and diversified the range of design possibilities. Embracing the computer as a design tool, and as a new means of communicating, I set about selecting a thesis topic that would allow me to explore and master these new tools. In selecting a topic, I was intrigued by the ability …
Using Measured Photography To Obtain Optimal Results From Ccd Color Scanners, David L. Milburn
Using Measured Photography To Obtain Optimal Results From Ccd Color Scanners, David L. Milburn
Theses
With the advent of desktop color scanners in the electronic prepress production environment, quality in color separations from transmissive originals has become erratic. The cause of this fluctuation is, in part, due to the transition from PMT to CCD-based scanning technology. Whereas, PMT scanners tend to have a broad dynamic range, that of CCD scanners is more limited. This characteristic adversely affects the quality of color separations by causing additional tone compression. An original transparency typically has a shadow density of 3.00 and a diffused highlight density of 0.30 for an overall density range of 2.70. On a four-color heatset …
An Investigation Of The Relationship Between Percentage Area Coverage And Ink Film Trapping, Daniel Garcia
An Investigation Of The Relationship Between Percentage Area Coverage And Ink Film Trapping, Daniel Garcia
Theses
An investigation of the relationship between percentage underneath area cover age and ink film trapping is presented. It is common knowledge that an ink generally adheres better to the paper than to a wet ink. This is known as undertrapping. To avoid this problem, printers set a limit for the total area coverage to be printed on the press sheet. The problem is that no formal study has been done to find the optimum point at which the limit should be set. The investigation addresses the issue of total area coverage from a trap ping point of view. This presents …
Design And Implementation Of An Asynchronous Version Of The Mips R3000 Microprocessor, Scott Siers
Design And Implementation Of An Asynchronous Version Of The Mips R3000 Microprocessor, Scott Siers
Theses
The goal of this thesis is to demonstrate the feasibility of converting a synchronous general purpose microprocessor design to one using an asynchronous methodology. This thesis is one of three parts that details the entire design of an asynchronous version of the MIPS R3000 microprocessor. The design excludes all of the memory support features of the processor for two reasons. First, the memory is already handled asynchronously and second, the size of the project must be limited. This design has implemented the entire set of instructions from the original synchronous version with the exception of certain memory instructions. The three …

A Digital Signal Processing-Based Predistortion Technique For Reduction Of Intermodulation Distortion, Richard James Buckley
A Digital Signal Processing-Based Predistortion Technique For Reduction Of Intermodulation Distortion, Richard James Buckley
Theses
Linearization of power amplifiers has been the topic of many studies, dating back to the work of H. S. Black in the 1920s. For many applications, the well-documented techniques of feedforward and feedback can be used to design low intermodulation distortion (IMD) amplifiers. However, certain applications, including the design of high-power, radio frequency amplifiers, preclude the use of these techniques. The work herein describes an alternative to presently accepted distortion reduction techniques. In-band IM distortion (multi-tone distortion located close in frequency to the desired signal) , is reduced by modifying a baseband input, upconverting this signal to the transmission frequency, …
The Use Of Plasma-Generated Silicon Dioxide-Like Coatings As Charge Storage Media For Electrets, Xiaorong Lin
The Use Of Plasma-Generated Silicon Dioxide-Like Coatings As Charge Storage Media For Electrets, Xiaorong Lin
Theses
The object of this project is to study the electret properties of silicon dioxide coating. Silicon dioxide coatings were produced by microwave plasma chemical vapor deposition under various conditions such as pressure, flow ratio, power, etc.. DC bias, thermionic emission and corona charge were used to produce charges in the silicon dioxide film. The results include measurements of deposition rate of silicon dioxide, the absorption wavenumbers, the thickness and index of silicon dioxide coating. The electret properties were focused on the charging process, charge distribution and charge decay rate.

Theses
I came to RIT, for a MFA in Computer Animation, with one aim in mind: to learn 3D animation. The most difficult part about my animation theses was finding a project that would challenge all that! had learned up to this point. I didn't want to just fly the camera around objects, as I'd seen in previous theses' and three dimensional animations. That was the easy way out! I set my goals high. I wanted to see if I could bring characters to life in 3D. I wanted to take traditional two dimensional character animation techniques and apply the movement …
A Study Of Techniques To Improve The Effective Resolution Of Thematic Mapper Thermal Infrared Imagery, Ranjit Bhaskar
A Study Of Techniques To Improve The Effective Resolution Of Thematic Mapper Thermal Infrared Imagery, Ranjit Bhaskar
Theses
This work is a study of existing and proposed approaches to improve the effective resolution of the thermal band of a multispectral image. Frequency domain filtering, magnitude and phase merging, and adaptive least squares approaches were implemented. Those techniques that utilized the inherent correlation between bands appeared to show the most promise. A two step procedure combining the point-by-point merging technique with a regional replacement filter generated the best results.

S.57392, Christine Lo
Theses
The idea of creating and writing a thesis loomed before me as an awesome task I would never be able to bring to fruition. However, the time came when I had to sit down and seriously ask myself how I would like to spend the remainder of my time here at RIT. Regretfully, I cannot say that there was a burning passion within me. I began to approach the thesis topic and asked myself, "What is out there that has yet to be fully explored?" Looking through several articles and speaking with a diverse group of people, I became involved …

Scanning Ratios For Desktop Imaging, Mike Beaulieu
Scanning Ratios For Desktop Imaging, Mike Beaulieu
Theses
Users of desktop scanning technology are conscious about the quality the image detail reproduction. Repeatability and accuracy are based on certain standards. Established scanning procedures for charged couple device (CCD) desktop scan ners are primarily influenced by the Nyquist Criterion which states that an image must be sampled at twice the frequency of the line screen ruling that will be used to print the final image. These "rules of thumb" appear in many techni cal and trade publications that are consulted by the printing industry in order to insure the quality of printed products. Quality is not the only factor …
Laboratory Investigation Of The Effect Of The Dampening Solution On The Loss Of Surface Strength Of Coated Paper, Chung-Ni Liu
Laboratory Investigation Of The Effect Of The Dampening Solution On The Loss Of Surface Strength Of Coated Paper, Chung-Ni Liu
Theses
Wet pick is thought to be caused by the presence of water used in lithography. The quantity of the wetting fluid, surface tension of the wetting fluid and the time interval between wetting and printing were tested to see if they affect the paper surface strength. Two rolls of web paper are pre-sampled from the RIT press room. One was found to exhibit the problem of wet pick while the other did not exhibit this defect. These papers were tested on the IGT Printability Tester in a manner similar to that predicted on press when a moisture film of 0.2 …
A Self-Timed Implementation Of The Bi-Way Sorter Systolic Array Processor, Mitchell Diamond
A Self-Timed Implementation Of The Bi-Way Sorter Systolic Array Processor, Mitchell Diamond
Theses
Self-timed circuits with an appropriate handshake control circuit can be used to replace the global clock in a VLSI chip. By replacing the global clock many problems which face designers have disappeared along with the clock. Some of these problems are due to clock skew and capacitance scaling with smaller feature sizes. The wire capacitance cannot scale below a certain limit due to two-dimensional effects, therefore the RC delays associated with the interconnect layers do not scale proportion.ally to the feature size. The resultant increase in wire delay makes it difficult to distribute a global clock at a high frequency. …
