Light Emission From Silicon, Frederick Seiferth

Theses

The electrochemical etching of crystalline silicon in hydrofluoric acid based solutions has been found to produce a porous layer, termed porous silicon (PS), which is found to exhibit photoluminescence (PL) and electroluminescence (EL) in the visible region. While the luminescence mechanism is the subject of much debate, the potential for this material is enormous as it could usher in a new generation of silicon-based optoelectronic devices. An electrolytic cell capable of producing luminescent layers of porous silicon over large area silicon wafers has been designed and fabricated. The stability of the PL of PS after subjection to standard microelectronic processing …

Multivariate Granulometry And Its Application To Texture Segementation, Mark Rzadca

Theses

Morphological granulometries were conceived by Matheron for the purpose of analyzing images with respect to shape and size of elementary granular components. In particular, granulometric analysis has proven useful in the analysis and identification of textures. Morphological granulometries are filter sequences that measure the residual area after each iteration of the filter. Every component of the filter's structuring element set is dilated for each iteration of the filter and the area resulting from the union of the morphological openings of the original image produces a function of a single variable, the iteration index. If the n components of the structuring …

The Need For A Specialized Treatment Center For The Elderly Population In St. Charles County, Sandi Klein

Theses

A most recent trend in the field of psychiatric health care has been to provide services for the elderly on highly specialized "geropsychiatric units" located within the confines of a general hospital and operated as a new component of the psychiatric treatment divisions.

Four local hospitals were surveyed regarding their in-patient mental health services for the elderly. The goal was to identify where geropsychiatric services were currently being offered and if their services were located on a special geropsychiatric unit, specific only to those patients over 65 years of age. Each hospital was surveyed as to the types of staff …

A Fund Raising Program For An Under Or Non Insured Critically Ill Child, John O'Mara Thompson

Theses

Research shows that fund raising for public or private uses has existed for centuries. Since the 1900's, fund raising efforts have become more organized with specific goals, plans, and time limits, yet they still generally serve the public and not individuals.

Life saving medical treatments that were once regarded as experimental are now readily available yet are not without financial constraints. Unfortunately, the very people who need health insurance to support such treatments find themselves unable to get insurance at any price. Thus, an urgent need for fund raising by private families to finance non compensated health care bills are …

A Plan To Integrate Cockpit Resource Management Into Training Programs Of Non-Automated, Transport Category Aircraft, C. H. Meyerholtz Jr.

Theses

Pilot error has been listed frequently as the probable cause of aircraft accidents. In most cases this does not refer to an error in piloting skills, but rather an error in judgment or inept use of resources available to the pilot. Researchers found that the skills required to effectively use all resources and encourage a team spirit in the cockpit had not been sufficiently developed. Further, according to the National Transportation Safety Board and the Federal Aviation Administration, these resource management skills are just as necessary as flying skills in order to effect safe flight. In the mid-1970's, cockpit resource …

Using Public Relations To Effectively Communicate A Desired Corporate Image Of The United States Postal Service, Dianne Holloway Williams

Theses

The United States Postal Service is a 219 year old American institution that for the majority of those years enjoyed the approval and confidence of the American people. Now, newspaper articles regularly ask whether this public service would be better managed as a private industry.

Sometime after World War II Americans began to lose faith in big business and in the government. The Postal Service was included among those institutions that began to lose public trust. More recently, numerous news reports point to an agency delivering poor service through unconcerned, perhaps even violent employees . This general distrust of government …

The Development And Evolution Of A Self-Supporting, In-House Public Relations Program In The Rockwood School District, Jeff Arnett

Theses

When the Rockwood School District implemented site-based management in 19 90, the change dramatically altered the district's overall communications program.

The responsibilities and funds to pay for requested services were given to each of Rockwood' s schools and departments. As a projects, which result, monies were formerly for communications budgeted to the communications department, were shifted to the individual school accounts. Site-based management had seemingly l eft the communications department with a reduced budget and the challenge of recovering the schools' money and maintaining their business.

What has evolved is a more effective program that also attempts to generate revenue …

Color in the computing environment, once considered a luxury, is becoming more available compared to being just the occasional exception. As the number of users exploring the uses of color through displayed and printed images increases, the problems associated with its use are becoming widely known. What worked in black and white is not easily translated into color. The use of color needs to begin with the basic understanding of what is color, its terminology and its utilization as an enhancement to communications tool. Only after the basic terminology and effective means of communication are understood will color flourish as …

An Occam2 Implementation Of Prolog, Manjula Motwani

Theses

Prolog has been widely recognized as a powerful programming language for artificial intelligence. It was also chosen as a kernel language for the Japanese Fifth Generation Project. The project is a large scale effort to initiate a new generation of computing. Due to the wide range of applications that Prolog has, many methods have been developed for extracting parallelism from standard Prolog in order to achieve faster execution on a multiprocessor. This project designs an execution model for Prolog, which attempts to exploit the parallelism mainly at the argument level through the unification operation. The model consisting of a number …

Suppression Of The Transient Response In Linear Time-Invariant Systems, Timothy P. Landschoot

Theses

Steady-state solutions represent the long-term response of linear systems due to specified input signals. The total response is initially contaminated with transients, which disguise the long-term/operating response of a system. Except for certain ideal cases, even in systems of low dimension, the steady-state solution is typically obtained by simulation of the system until the transient part of the response is sufficiently negligible. This investigation elaborates on a method of determining the initial conditions that spontaneously give rise to steady-state solutions of forced linear differential equations. The method is applicable to stable, as well as non-stable systems, of any order.
