Decentralized Optimal Control With Application To Dynamic Routing In Computer Communication Networks, Ning Wang

Dissertations

This research considers the dynamic routing problem of computer communication networks in the framework of decentralized control theory. The routing dynamics are modeled in terms of a state equation with multiple controllers. Routing, or control of message flow, is formulated as an optimal control problem with multiple decision makers. Each decision maker may have access to different set of information and work cooperatively to optimize a common system performance index.

Necessary and sufficient conditions for optimality are derived for a system with a deterministic and a stochastic traffic patterns under a linear information structure and a quadratic performance index. The …

Cabinet-Making And The Contemporary Imagination, Daniel Bailey

Theses

Before becoming a serious woodworker, I was preoccupied with other art forms, primarily contemporary poetry and fiction. Film, sculpture, painting, music, and performance also seemed to be powerful genres in which the imagination could manifest itself most directly, and influence human lives with a magical force. As an undergraduate in the early 1970's, I received a degree in literature. At that time the poetry readings I attended in New York City were as important as the books and ideas to which I was exposed in a progressive classroom situation. What I gained from this experience was a particular sense of …

Dance Therapy And Self-Concept Change In Psychiatric Patients, Cheryl Jeanne Hall

Dissertations and Theses

This study investigated the effects of various forms of therapy (individual, occupational, and dance) on self-concept. Subjects were 29 psychiatric patients at Providence Medical Center who volunteered to participate in this study. The Tennessee Self-Concept Scale (TSCS) was used to measure self-concept both at time of admission and prior to discharge. The data were analyzed in a step-wise multiple regression to determine which of the various forms of therapy are the best predictors of self-concept at second TSCS application. The results of the step-wise multiple regression did not support the hypothesis that exposure to dance therapy would be a significant …

An Exploratory Study Of Adolescents' Communicative A Ttitudes, Perceptions Of Behavior, And Life Change Events As Potential Factors In Development Of Essential Hypertension, Susan Heath Falvo

Student Work

In the past 50 years, social scientists and medical researchers have explored many aspects of human behavior and the psyche which appeared related to various physical disorders. This endeavor evolved into a discipline known as "psychosomatic medicine." Methodologies and perspectives within this discipline have varied widely over the years and many studies have yielded Inconclusive findings (Lipowski, 1977; Lazarus, 1980). However, a review of the psychosomatic literature reveals a t least one common dimension: the nature of one's face-to-face transactions is vitally linked to one's physical well-being.

One medical researcher who described the relationship between human Interaction and physiological processes …

"Theophilus North", James W. Eisenhardt

Student Work

I was born an identical twin, and the twin only lived a few hours, but he would have been called Theophilus; so, this is my other self. The framework is the same as mine, but he's a very different fellow from me; so, it's how my life might have been had I been born that other fellow. It's first autobiography and then fiction, but I don't know of any other work where the author was imagining himself as his anti-self. I'm dutiful, I’m conscientious, I’m school masterish, but Theophilus is a helluva fella. A liar but a very good man--and …

Food Quality Control Methods Used In Nursing Homes And Hospitals Of 100 Beds Or Less In Kentucky And Tennessee, Laura Lee Butler

Doctoral Dissertations

In 1981 nursing homes and hospitals with less than 100 beds in Kentucky and Tennessee represented approximately 50% of the total number of these facilities. Little attention has been given in the professional literature to health care facilities of this size. Many small facilities have not employed persons with specialized education and training to manage the foodservice; thus food quality control methods may not be used. Research is needed to identify existing areas of quality control in order for needed improvements and changes to be made. The purposes of this study were to identify and compare current quality control measures …

An Experimental Study Of Temperature Separation In Swirling Flow, Hiromoto Kuroda

Doctoral Dissertations

The objective of the present investigation is to substantiate the mechanism of acoustic streaming; this was carried out by conducting detailed internal surveys of a Ranque-Hilsch swirling flow test rig at the condition when the vortex whistle was attenuated or excited. This control of the vortex whistle was accomplished by two methods.

In the first method where the vortex whistle was attenuated by placing a restriction at the exhaust, a Rankine vortex was observed to form, accompanied by an almost uniform total temperature distribution in the radial direction except for a dip near the vortex core; when the vortex whistle …

Using Anthropological Approaches In A Human Service Setting, Steven Alan Erickson

Masters Theses

Public criticism of human service organizations has underlined the fact that there are essential differences between organizations which provide services and organizations which produce goods. As service providers, human service organizations represent an organized response to human needs and problems, but this response is affected by different assumptions about people's ability or inability to meet their own needs. The process of providing services entails a number of interactions at various levels between the organization and the community. These relationships are as complex as the people and social systems of which our pluralistic society is comprised, but there are special manifestations …

Masters Theses

Geophysical techniques such as magnetic and electrical resistivity methods are being increasingly applied in investigations of landfills.

For this survey, measurements of the intensity of the earth's magnetic field were taken at regular intervals along traverses. Resistivity readings were taken at selected intervals along the same or very similar traverses. Additional resistivity depth measurements or soundings were obtained at selected points in and around the landfill.

Profiles were analyzed for individual dump structures and for overall magnetic and resistivity response. Contour maps were drawn from the measurements at the site to depict broad trends or patterns. Deeper subsurface geology was …

Study Of Bagasse Pulps To Obtain Corrugated Medium, Maria A. Carbonari

Paper Engineering Senior Theses

Bagasse was used as raw material to pulp various NSSC, Soda and Kraft liquors and evaluated as corrugating medium. A new pulping procedure with the M & K Digester was developed in order to reach maximum temperature at the shortest practical time.

It was found that a 10% Active Alkali at 5% Sulfidity and an NSSC liquor at pH 10 with 15% SO₂ on pulp gave suitable strength properties. The NSSC cook gave a higher yield but a pulp with more shives.

Keywords: Bagasse, Kraft, Soda, neutral sulfite semichemical, corrugating medium

Cleaning And Upgrading Of Post Consumer Corrugated Containers As A Secondary Fiber Source, Daniel L. May

Paper Engineering Senior Theses

Introduction

The use of secondary fiber as a source of raw material in the paper industry is now an important reality ingrained into papermaking. The reasons for using secondary fiber are many and diversified but most point to economy as the primary factor. With wood and virgin pulp becoming more expensive, secondary fiber will undoubtedly maintain its place in the industry and may increase in the future. Total paper production is approaching 88,000,000 tons. Of this total only 23,000,000 is recycled. With nearly 64% of total paper production going to waste either through landfill, incineration or other disposal methods it …

Effect Of Hot Supercalendering On Sheets With High Filler Loadings And Polypropylene Fibers Added, Michael R. Whitescarver

Paper Engineering Senior Theses

This study investigates the effects of hot supercalendering on sheets with high filler loadings and polypropylene pulp added. An uncoated sheet that had sheet and optical characteristics similar to a coated number three sheet. was desired. Research was conducted in two stages, handsheet analysis and a machine trial on Western Michigan University's Fourdrinier Pilot Plant. The hot supercalendering of these sheets with 15% Pulpex resulted in a 111% increase in Scott Bond. Unconsolidated Pulpex has no synergestic effects with clay fillers for gloss, brightness, and opacity. Pulpex that has been consolidated does have a synergistic effect with clay for gloss.

The Cultural Roots Of Behaviorism, Juan Mario Herakovic

Masters Theses

This thesis traces some of the economic, social, religious and political events that played an important role in the development of behaviorism in the United States. The effects of the Enlightenment, the dislocation of moral and social values, the decline of religion, political upheavals and increased immigration, are seen as destabilizing elements in American society. Emphasis is placed upon the specific values of the American society, and the way in which these values remained constant throughout the social history of the United States. As such, behaviorism represents a scientific approach to the historical continuity of ideas within the nation.

The Effects Of Caffeine Alone, And In Combination With Nicotine, On Several Behaviors In Rats, Judith S. Devoe

Masters Theses

Several doses of caffeine-sodium benzoate (0.0, 2.5, 5.0, 10.0 & 20.0 mg/kg, stated as salt) were administered daily by intraperitoneal injections (IP) for an initial twelve consecutive days which constituted Phase I. A probe-dose of nicotine (2.0 mg/kg) was administered in combination with each caffeine dose for the following seven days comprising Phase II. Removal of nicotine subsequent to the last day of Phase II initiated a second caffeine-only (nicotine withdrawal) condition, Phase III. Tests of locomotion and aggression ensued at various points of the study and water intakes and body weights were recorded daily, prior to injections. Overall, locomotion …

The Socio-Cultural Transformation Of Japanese Medical Systems, Takako Matsunaga

Masters Theses

Medical systems, just as other social institutions, are not stable and, thus, are subject to change. This essay is an analysis of the socio-cultural transformation of Japanese medical systems in general, and of the "health care system" of the cosmopolitan medical system in particular. No medical system is able to provide problem free medical care to any given population. Thus, the current health issues and changes in health seeking/enhancing behavior in contemporary Japan is examined as the reflection of the maladaptive nature of cosmopolitan medicine to its environment.

The Geology Of The Southern Bull Mountain Area, Jefferson County, Montana, Michael Edward Streeter

Masters Theses

The Late Cretaceous-Early Tertiary Laramide orogeny was responsible for the northward tilting of the pre-Eocene rocks of the area. The Late Cretaceous deposition of the Elkhorn Mountains Volcanics resulted in the volcanic-Madison Group unconformity. Late Cretaceous faulting took place probably in response to caldera subsidence. Laramide uplift erosion and downstream transport resulted in the deposition of the Conrow Creek conglomerate and debris flows over the Lodgepole Limestone. Block faulting took place in response to regional extension probably during Late Oligocene-Early Miocene time resulting in the formation of the St. Paul's Gulch, Golden Sunlight, and Boulder basin faults. The Oligocene Dunbar …

The Use Of Old Corrugated Board In The Manufacture Of High Quality White Papers, Rene H. Kapik

Paper Engineering Senior Theses

Clean corrugated board waste was fractionated into its softwood/hardwood fiber components, repulped using a kraft pulping process, and bleached using a CEHD bleaching sequence in an effort to produce high brightness fiber suitable for use in medium to high quality white paper.

The papers produced has almost equivalent mechanical strengths and opacity, but possessed unsatisfactory brightness and cleanliness when compared to commercially manufactured bleached kraft pulps of identical softwood/hardwood contents.

Based on this experimental data, the use of recycled fiber from corrugated board as a fiber substitute in the manufacture of high quality printing and writing papers is not recommended …
