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 …

Effects Of Chromatic Surrounds On The Perceived Color Balance Of Reflection Prints, David R. Odgers

Theses

Many have pursued an understanding of factors that affect color perception. One such factor is the viewing condition under which an observation occurs. For example, the appearance of a color patch is altered by the color and luminance of the area surrounding it. Even if this perception is subconscious, it still influences the viewer's judgments. Thus, one expects that the perception of a complex scene, a photograph, will also be changed by a colored surround. This paper investigates such an effect, thereby increasing the understanding of color perception.

The system explores a question format different from the traditional formats of multiple choice, true-false, and fill-in-the-blank which are available in current authoring systems. The question format to be explored allows the student to identify …

An Algorithmic Approach For Multi-Color Ramsey Graphs, Wei Li

Theses

The classical Ramsey number R(r1,r2,...,rm) is defined to be the smallest integer n such that no matter how the edges of Kn are colored with the m colors, 1, 2, 3, . . . ,m, there exists some color i such that there is a complete subgraph of size ri, all of whose edges are of color i. The problem of determining Ramsey numbers is known to be very difficult and is usually split into two problems, finding upper and lower bounds. Lower bounds can be obtained by the construction of a, so called, Ramsey graph. There are many different …

The Optical Spread Functions And Noise Characteristics Of Selected Paper Substrates Measured In Typical Reflection Optical System Configurations, Janet L. Kofender

Theses

Research into the signal and noise characteristics that ultimately determine the performance quality of an imaging system has done little to isolate the contribution of the final image carrying substrate. A study is presented that experimentally analyzes some optical characteristics of six paper substrates representative of those used in lithography, xerography and photography. The optical characteristics studied can have a direct impact on image quality and are a result of the paper structure and its light scattering properties. Reflection microdensitometer techniques are used to provide representations of optical spread functions and an analysis of paper noise which is quantified as …

Ipl: Interfaced Prolog/Lisp, Steven J. Recard

Theses

This thesis report describes the design and implementation of an interface between the two most common artificial intelligence languages, Lisp and Prolog. The interface is accomplished by small extensions to each language, and provides Prolog programs with the capability of invoking Lisp functions. The interface is simple yet powerful; it the supports passing of arbitrarily complex data objects, regardless of data type. The particular language implementations extended were C-Prolog [Pereira,85] and XLISP [Betz,86], both interpreters running under the Unix operating system.

Create A New Town And A New You To Improve Writing Skills, Barbara Broadfoot

Theses

Writing has always been one of the corners tones of American education . Schools are concerned with the development of students, and writing contributes to the development of the whole person. The public is alarmed because many students graduate from high school without being able to write well enough to function in today's complicated society.

There a re many reasons why schools fail to do a good job in the teaching of writing. One of the main reasons is the schools' over-emphasis on the teaching of grammar. Many teachers are not trained as teachers of writing and rely on the …

The Prediction Of Edge Raggedness Via A Single-Channel Filter Model Of The Visual System, Michael G. Mannix

Theses

Edge raggedness is a psychophysical term which refers to the fidelity of a high-contrast edge, which has been degraded by some process, compared to an ideal edge. It has been suggested that the processing of high-contrast edges shares the same spatial-frequency processing mechanisms with that of sinewave gratings. This study uses first-order psychophysical principles, determined using sinewave grating stimuli, in a model to process edges in order to derive a quantitative metric proportional to perceived edge raggedness. The derived metric is the rms power of the processed edge power spectrum. First, the need for a two-dimensional analysis is established, then …

A Data Compression System Using Arithmetic Code, Seokrim Choi

Theses

Generally it is difficult to compress data, from statistically unknown sources, with significant compression ratio. To achieve this, the compression scheme should have an ability to gather context information of the source, adaptively. For better compression, it is desirable to separate the context gathering scheme from coding itself. Arithmetic code is very flexible and can accept any kind of context gathering scheme which can generate probabilities. One context gathering algorithm which generates Markov type probability adaptively is studied and implemented in software using Arithmetic code. This scheme performs well and results in compression ratio better than any existing algorithms such …

A Study Of White-Collar Clerical Productivity : Composition, Issues And Implications For Human Resource Planning, Sheila Devereaux

Theses

During the past decade, there has been a growing concern and focus over declining American productivity. Declining productivity requires long-range thinking, and fundamental changes on the part of government, labor and management.

One of the major contributors identified is the labor force. What has gone unmeasured for years is the white-collar clerical workforce. The service sector has become the most dominant area where clerical workers have increased, consequently, productivity issues have become a top priority.

Management must assess the implications of losses in turnover, absenteeism, performance lag, and morale that affects bottom-line profits. Management is under pressure to develop action …

Fibrin Glue For Spilt-Thickness Skin Grafts And Microsurgical End-To-End Arterial Anastomoses In Live Rats, Susan Diane Drastal

Theses

Fibrinogen and thrombin were combined to make a "glue" for adherence in microvascular anastomoses and split-thickness autologous skin grafts in rats. The powdered human fibrinogen and bovine thrombin were mixed with sterile water and each applied drop-wise through separate syringes in equal concentrations. A gelatinous clot formed in 10 seconds, and was completely coagulated in 45 seconds. In part I, one-half of the group had their grafts sutured, and one-half had their grafts glued in place.

In part II, microvascular arterial anastomoses were performed. Group I had their arteries reanastomosed using sutures only; group II had their arteries reanastomosed by …

The Degradation Of Trace Pollutants In Wastewater, Christine M. Cheng

Theses

The effect of different treatments on the degradation of chlorinated organic pollutants in wastewater has been studied. The model compound investigated was para-chlorophenol. The different treatments used were ozone, UV irradiation, ultrasound, air flow and pure oxygen.

It is concluded that ozone has the greatest effect, ozone-UV irradiation follows closely behind, and UV irradiation has much less of an effect in degrading the p-chlorophenol.

P-chlorophenol was found to have an immeasureably slow degradation rate when treated with air even at an elevated temperature of 55°C.

The oxygen, at room temperature, showed a degradation of p-chlorophenol which, although small, was much …
