Methods For Minimizing Performance Degradation Caused By Branch Delays, Debbie St. Onge

Theses

The presence of branch instructions in an instruction stream may adversely affect the performance of a processor by introducing significant delays in the execution process. As processors become more pipelined, the impact these delays have upon performance increases. This thesis investigates why delays occur when branch instructions are encountered. It also summarizes various hardware methodologies which can alleviate the performance degradation due to these delays. Simulation results show that these hardware methodologies can improve branch performance by up to 45 percent. Some branches are inherently necessary in order to implement programming decisions. However, the use of branches within programs can …

The Interrelationship Of Graphic Design And Fine Art, Antoinette Monnier

Theses

The graphic designer is a visual communicator who transmits messages from a client to an audience. The message must be clear and free of the distracting presence of the designer, because a designer's personal biases and feelings are irrelevant to the client's message. However, work produced by some contemporary designers has challenged the notion of clear visual communication and problem-solving. It is self-expressive, ambiguous, and open to interpretation, taking on characteristics traditionally associated with fine art rather than graphic design. While the production and viewing of some graphic design is becoming a more private experience, the reverse is true in …

A Computational Analysis Of Observer Metamerism In Cross-Media Color Matching, Richard Alfvin

Theses

Standard color-matching functions are designed to represent the mean color-matching response of the population of human observers with normal color vision. When using these functions, two questions arise. Are they an accurate representation of the population? And what is the uncertainty in color-match predictions? To address these questions in the dual context of human visual performance and cross-media reproduction, a color-matching experiment was undertaken in which twenty observers made matches between seven different colors presented in reflective and transmissive color reproduction media and a CRT display viewed through an optical apparatus that produced a simple split field stimulus. In addition, …

Convergence Of Adaptive Morphological Filters In The Context Of Markov Chains, Yidong Chen

Theses

A typical parameterized r-opening *r is a filter defined as a union of openings by a collection of compact, convex structuring elements, each of which is governed by a parameter vector r. It reduces to a single parameter r-opening filter by a set of structuring elements when r is a scalar sizing parameter. The parameter vector is adjusted by a set of adaptation rules according to whether the re construction Ar derived from r correctly or incorrectly passes the signal and noise grains sampled from the image. Applied to the signal-union-noise model, the optimization problem is to find the vector …

Polarization Modulation And Splicing Techniques For Stressed Birefringent Fiber, Risa Robinson

Theses

A study has been conducted in the areas of polarization modulation and splicing techniques for a polarization maintaining PANDA type fiber. Polarization modulation was achieved by compressing the fiber both along the fast and slow axes. A sensitivity of 16.69 rad/(g/um) and 27.56 rad/(g/um), corresponding to a maximum phase diffrerence of 2.39 radians and 3.96 radians for compressing along the x and y birefringent axis, respectively, was achieved, with the compression material complying to a 15 degree arc around the fiber circumference. Polarization cross coupling was measured to be 0.6% for compressing with a force of 1.3 g/um. Polarization cross …

The Effects Of Inlet Water Temperature On Condensing Film Coefficiencts, Alan Smith

Theses

This experiment investigated the effects of the inlet water temperature on the overall condensing heat transfer coefficient in a surface condenser. The results of the testing during the investigation were used to determine a temperature correction factor which was then compared to the correlation published by the Heat Exchange Institute ' . The comparison revealed that the correlation published by the Heat Exchange Institute is not accurate for inlet water temperature less than 65 F and greater than 75 F. In addition, a comparison was made between the overall heat transfer coefficient that was obtained by experiment and the overall …

The Influence Of Format On Accessibility, Audrey Sumberg

Theses

The initial idea for this thesis project stems from an interest in artists' books. Of particular interest is the way in which the physical format of the book can be an integral part of the artistic concept. Artists' books are books as art rather than books about artists or their work. As such, they exceed the boundaries of conventional expectations. They are about themselves, not simply passive vehicles for carrying information. The "reader" experiences an artist's book in much the same way the viewer experiences a painting, a sculpture, or a ceramic vase. The format for carrying information is as …

Modeling The Fate Of Volatile Organic Compounds In Wastewater Treatment Facilities; Implementation Of Volatilization Models In Envirocad, Vinita Chhahira

Theses

The 1990 Clean Air Act Amendments have identified wastewater treatment facilities as a major source of volatile organic compound (VOC) emissions. VOCs present in wastewater discharges affect the quality of receiving waters, while emissions to the air affect downwind populations. The primary mechanisms involved in VOC removal from a wastewater treatment facility are volatilization and stripping, biodegradation, and sorption to either suspended or biological solids. Although many models have been developed to predict the fate of VOCs in wastewater treatment facilities, no model completely predicts emissions for an entire wastewater treatment facility. The focus of this work is to incorporate …

Integration Of Pneumatic Fracturing And In Situ Vitrification In Coarse Grained Soils, Sean Thomas Mcgonigal

Theses

This thesis investigates conceptual integration of the Pneumatic Fracturing (PF) process with In Situ Vitrification (ISV) for remediation of contaminated soil. Integration will permit ISV melts to be initiated below the ground surface and extend the depth of the ISV process.

Bench scale experiments were conducted in 4.9 ft³ (0.14 m³) Plexiglas tanks filled with a test soil that was specifically blended to simulate the Hanford Formation in Richland, WA. Discrete pneumatic fractures were successfully created and filled with the ISV starter path material. Conductivity measurements made across two graphite electrodes exhibited a pre-fracture soil resistance of …

Dream Tree, Kyoung-Choul Cha

Theses

The purpose of this thesis is to sublimate the primitive images of nature. These images are based on my observation of nature's aesthetic value. I have developed an intimate relationship with nature, particularly with the tree. I have explored a variety of tree shapes as well as expressed their inherent liveliness. The outdoor sculptural pieces which make up the series "Dream Tree" are evidence of the connection between human lives and trees.

The Economical Feasibility Of Computer-To-Plate Technology For Use In Magazine Production, Chih-Ming Chen

Theses

Computer-to-Plate (CTP) technology has been used for newspaper and book production and been proved successful by several print houses. However these publications are mostly printed with less color and advertisments. Therefore, these fit into the niche market of CTP technolo gy. What about magazine production? Since magazine production normally requires more color, more advertisements, higher quality, can we still make profits from this new idea without a resulting loss of quality? State-of-the-art CTP technology is capable of producing high quality images, and large format. The time savings and labor savings are the biggest advantages. In addition to this, side profits …

A Study Of The Preferability Of Desktop Generated Color Separations Over High End Generated Color Separations In Newspaper Printing, Robert Foster

Theses

Over the last decade, newspapers have been compelled to introduce a lot more process color to their pages. This coincides with the introduction of USA Today, but also with the fact that all forms of media, including television and magazines, have become significantly more colorful. There is considerable market pressure on newspapers to be colorful, as well. Continued audience interest and advertising dollars are at stake. This is not a trivial issue. At the same time, newspapers are being admonished to make sure that, if they do introduce color to their pages, then it should be of high quality. Low …

Using Color Management To Automate The Color Reproduction Of 3-D Images Procured Via A Digital Camera/3-D Scanner, Kristl Honda

Theses

The use of digital photography is migrating from the major applications in pho tojournalism to professional studio photography. Traditional service bureaus such as professional photo labs and prepress trade shops are adding digital imaging services to their film-based services. Also, businesses such as advertising agencies and publishers, who traditionally outsource work to service bureaus, are bringing digital imaging services in-house. State of the art imaging technology empowers users with new tools, but does not guarantee that the task of generating accept able image reproductions will be easier. The basic problem in the desktop color prepress environment is that each com …

The Design, Construction, And Implementation Of An Engineering Software Command Processor And Macro Compiler, Jesse Coleman

Theses

This paper presents the design and construction of a software translator that serves as a foundation, or central engine, around which an entire engineering software system can be constructed. To provide the user with a powerful interface to drive an application, a high-level procedural language similar to FORTRAN or BASIC is integrated into the translator. An application shell was also written to provide the user with an interactive command line environment for using the translator. The translator, language, and application shell together mechanize a programming and command interpreter environment. Users can interactively enter commands from the keyboard or load and …

Electromechanical Surface Damping Combining Constrained Layer And Shunted Piezoelectric Matetrials With Passive Electrical Networks Of Second Order, Carlos Velazquez

Theses

An electromechanical surface damping (EMSD) technique is proposed. This technique combines two surface damping methods, the shunted piezoelectric-ceramic damping with the viscoelastic constrained layer damping (CLD). The damping contribution of the shunted piezoelectric intends to enhance the effective frequency range of the CLD. Piezoelectric ceramics provide similar damping characteristics to viscoelastic material when they are shunted with resonant electrical networks. A resonant shunting circuit provides the opportunity of tuning (shifting) the effective damping range of the piezoelectric into an arbitrary frequency, enhancing the damping at the vicinity of such frequency. Also, the EMSD technique proposes the use of a multiple …

A Study Of Ellipsoidal Variance As A Function Of Mean Cielab Values In A Textile Data Set, Seth Ansell

Theses

An analysis of the variances of a set of colored textile patches, sampled from the Scott-Munsell textile set, relative to their mean values, demonstrated several systematic trends. Overall, the amount of variance in the data as expressed by the shape and the orientation of the ellipsoids was found to be greatest in the L direction. Additionally, the shape and orientation of the ellipsoids was determined to be largely a function of chroma and lightness. No overall correlation was found between the distribution of the ellipsoidal volume and their hue or chroma. However, with exceptions, ellipsoidal volume peaked in patches with …
