Applied Real-Time Integrated Distributed Control Systems: An Industrial Overview and an Implemented Laboratory Case Study

This thesis dissertation mainly compares and investigates laboratory study of different implementation methodologies of applied control systems and how they can be adopted in industrial, as well as commercial, automation applications. Namely the research paper aims to assess or evaluate eventual feedback control loops' performance and robustness over multiple conventional or state-of-the-art technologies in the field of applied industrial automation and instrumentation by implementing a laboratory case study setup: the ball on beam system. Hence, the paper tries to close the gap between industry and academia by: first, conducting a historical study and background information of main evolutional and technological eras in the field of industrial process control automation and instrumentation. Then, some related basic theoretical as well as practical concepts are reviewed in Chapter 2 of the report before displaying the detailed design. After that, the next Chapter, analyses the ball on beam control system problem as the case studied in the context of this research through reviewing previous literature, modeling and simulation. The following Chapter details the proposed design and implementation of the ball on beam case study as if it is under the introduced distributed industrial automation architecture. Finally, Chapter 5 concludes this work by listing several …

Grayson County, Texas, in Depression and War: 1929-1946 (open access)

Grayson County, Texas, in Depression and War: 1929-1946

The economic disaster known as the Great Depression struck Grayson County, Texas, in 1929, and full economic recovery did not come until the close of World War II. However, the people of Grayson benefited greatly between 1933 and 1946 from the myriad spending programs of the New Deal, the building of the Denison Dam that created Lake Texoma, and the establishment of Perrin Army Air Field. Utilizing statistical data from the United States Census and the Texas Almanac, this thesis analyzes the role of government spending‐federal, state, and local‐in the economic recovery in Grayson County.

Characterization of Aprotic Solutes and Solvents Using Abraham Model Correlations (open access)

Characterization of Aprotic Solutes and Solvents Using Abraham Model Correlations

Experimental data were obtained for the computation of mole fraction solubilities of three dichloronitrobenzenes in organic solvents at 25oC, and solubility ratios were obtained from this data. Abraham model equations were developed for solutes in tributyl phosphate that describe experimental values to within 0.15 log units, and correlations were made to describe solute partitioning in systems that contain either "wet" or "dry" tributyl phosphate. Abraham model correlations have also been developed for solute transfer into anhydrous diisopropyl ether, and these correlations fit in well with those for other ethers. Abraham correlations for the solvation of enthalpy have been derived from experimental and literature data for mesitylene, p-xylene, chlorobenzene, and 1,2-dichlorobenzene at 298.15 K. In addition, the enthalpy contribution of hydrogen bonding between these solutes and acidic solvents were predicted by these correlations and were in agreement with an established method. Residual plots corresponding to Abraham models developed in all of these studies were analyzed for trends in error between experimental and calculated values.

Assessing Measurement Equivalence of the English and Spanish Versions on an Employee Attitude Survey Using Multigroup Analysis in Structural Equation Modeling. (open access)

Assessing Measurement Equivalence of the English and Spanish Versions on an Employee Attitude Survey Using Multigroup Analysis in Structural Equation Modeling.

The study utilized the covariance structure comparison methodology - Multigroup Analysis in Structural Equation Modeling - evaluating measurement equivalence of English and Spanish versions of an employee opinion survey. The concept of measurement equivalence was defined as consisting of four components: sample equivalence, semantic equivalence, conceptual equivalence and scalar equivalence. The results revealed that the two language versions of the survey exhibited acceptable measurement equivalence across five survey dimensions Communications, Supervision, Leadership, Job Content & Satisfaction and Company Image & Commitment. Contrary to the study second hypothesis, there was no meaningful difference in opinion scores between English-speaking and Spanish-speaking respondents on the latent construct of Job Content & Satisfaction.

Interweaving History: The Texas Textile Mill and McKinney, Texas, 1903-1968. (open access)

Interweaving History: The Texas Textile Mill and McKinney, Texas, 1903-1968.

Texas textile mills comprise an untold part of the modern South. The bulk of Texas mills were built between 1890 and 1925, a compressed period of expansion in contrast to the longer developmental pattern of mills in the rest of the United States. This compression meant that Texas mill owners benefited from knowledge gained from mill expansion elsewhere, and owners ran their mills along the same lines as the dominant southeastern model. Owners veered from the established pattern when conditions warranted. This case study focuses on three mills in Texas that operated both independently and as a corporation for a total of sixty years. One mill in McKinney dominated the economy of a small town and serves as the primary focus of this paper. A second mill in Waco served a diversified economy in the center of the state; and the third mill, built in Dallas was concentrated in a major city in a highly competitive job market. All three of these mills will illuminate the single greatest difference between Texas mills and mills elsewhere, the composition of the labor force. Women did not dominate the mill labor force in Texas nor did children, except in limited cases, make-up a …

Consumer-Buying Objectives in Homemaking Courses in High Schools of the Southern Region (open access)

Consumer-Buying Objectives in Homemaking Courses in High Schools of the Southern Region

For the past few years the homemaking courses has shifted its emphasis from cooking and sewing skills to the solving of managerial problems of the individual and the family of today. Each person who is taking an active part in living is constantly purchasing and consuming goods and services and must realize that his welfare depends upon the relation between the satisfactions that he receives from the things he buys and the price that he pays for them. Since every one must purchase goods, the high school student needs to learn how to buy wisely. The executive committees of the homemaking divisions in the different states which are revising the courses of study realize that management of money from the consumer-buying view point is important and needs a place in meeting the needs and interests of the high school student of today. The problem in this study is to determine the adequacy of the objectives on consumer-buying in the homemaking courses in high schools of the Southern Region. This study is made for the purpose of determining the adequacy and extent of consumer-buying teaching objectives in homemaking education in the high schools of the Southern region. in order that way …

The Vital Imperative of Oswald Spengler's Philosophy of History (open access)

The Vital Imperative of Oswald Spengler's Philosophy of History

This investigation deals with the underlying motivation of Oswald Spengler in The Decline of the West. Sources include the published and translated works of Spengler: books, essays, and selected letters. Contingent areas of exploration, arranged in separate chapters, are the philosophy of history, using the works of Dilthey and Herder; philosophy, using the concepts of Husserl's Phenomenology, Bergson's Time and Free Will, and Goethe's Conversations with Eckermann; the contemporary human potential psychology of Abraham Mazlow and Rollo May, and the contemporary philosophy of Alan Watts and Ortega y Gasset. R. G. Collingwood as critic of Spengler is dealt with. The conclusion is drawn that Spengler did not attempt a system of history except as a vehicle for expressing a directive to live fully in the eternal now.

Dangerous, Desperate, and Homosexual: Cinematic Representations of the Male Prostitute as Fallen Angels (open access)

Dangerous, Desperate, and Homosexual: Cinematic Representations of the Male Prostitute as Fallen Angels

The purpose of this study is to frame the cinematic male prostitute as a "fallen angel" to demonstrate that the evolution of the cinematic hustler has paralleled historicized ideological definitions of male homosexuality. Because cultural understandings of male homosexuality frequently reflect Judeo-Christian ideological significations of sin and corruption, the term "fallen angel" is utilized to describe the hustler as a figure who has also succumbed to sin due to his sexual involvement with other men. This study constructs an epochal analysis of eight films that explores the confluence of the social understanding of homosexuality with the cinematic image of the hustler from the mid 1960s through the present. In doing so, this study shows that the image of the cinematic hustler is intricately tied to the image of the male homosexual in material cultures and eras that produce them. A filmography is included.

Clarence R. Huebner: An American Military Story of Achievement (open access)

Clarence R. Huebner: An American Military Story of Achievement

In the eyes of the American public excellence is often overshadowed by brilliance of personality. This is particularly true in the portrayal of many of the country's military leaders in World War II. A prime example of this phenomenon is Douglas MacArthur, whose larger than life persona made him a newspaper fixture during the war despite a series of strategic and tactical blunders that would have led to the sacking of a less visible (and publicly popular) leader. At the level of divisional commanders, this triumph of brilliance over excellence is best exemplified by the two primary leaders of the country's 1st Infantry Division, Terry de la Mesa Allen and Clarence R. Huebner. One was a hard-drinking, swashbuckling leader who led by almost the sheer force of his personality; the other, a plain spoken, demanding officer who believed that organization, planning and attention to detail were the keys to superior battlefield performance. The leadership differences between Allen and Huebner have been documented in multiple publications. What has not been documented is the life of the truly overshadowed general - Huebner. Huebner's transition to the leadership of the 1st Infantry Division (1st ID) constitute only a small period in a military …

Gewesener Magdeburgische Musicus: An Examination into the Stylistic Characteristics of Heinrich Grimm's Eight-Voice Motet, Unser Leben Wehret Siebenzig Jahr'

Although Magdeburg cantor Heinrich Grimm was frequently listed among prominent musical figures of the early seventeenth century such as Heinrich Schütz, Johann Hermann Schein, and Michael Praetorius in music lexica through the nineteenth century, he has almost disappeared from modern scholarship. However, a resurgence in Grimm studies has begun in recent years, especially in the areas of biographical study and compositional output. In this study, I examine the yet unexplored music-analytic perspective by investigating the stylistic characteristics of Grimm's 1631 motet, Unser Leben wehret siebenzig Jahr'. Furthermore, I compare his compositional technique to that of his contemporaries and predecessors with the goal of examining the work from both Renaissance and Baroque perspectives.

A Pre-professional Institution: Napoleon’s Marshalate and the Defeat of 1813 (open access)

A Pre-professional Institution: Napoleon’s Marshalate and the Defeat of 1813

Napoleon’s defeat in 1813 generates a number of explanations from historians regarding why he lost this epic campaign which ultimately resulted in France losing control over the German states. Scholars discussing the French marshalate of the Napoleonic era frequently assert that these generals could not win battles without the emperor present. Accustomed to assuming a subordinate role under Bonaparte’s direct supervision, these commanders faltered when deprived of the strong hand of the master. This thesis contributes to this historiographical argument by positing that the pre-professional nature of Napoleon’s marshalate precluded them from adapting to the evolving nature of warfare during the First French Empire. Emerging from non-military backgrounds and deriving their capabilities solely from practical experience, the marshals failed to succeed at endeavors outside of their capacity. An examination of the military administration of the Old Regime, the effects of the French Revolution on the French generalate, and the circumstances under which Bonaparte labored when creating the imperial marshalate demonstrates that issues systemic to the French high command contributed to French defeat in 1813. This thesis also provides evidence that Napoleon understood this problem and attempted to better prepare his marshals for independent command by instructing them in his way …

Evaluating a Sustainable Community Development Initiative Among the Lakota People on the Pine Ridge Indian Reservation

This thesis details my applied thesis project and experience in the evaluation of a workforce development through sustainable construction program. It describes the need of my client, Sweet Grass Consulting and their contractual partner, the Thunder Valley Community Development Corporation, in the evaluation of Thunder Valley CDC's Workforce Development through Sustainable Construction Program. My role involved the development of an extensive evaluation package for this program and data analysis of evaluation materials to support Thunder Valley CDC's grant-funded Workforce Development Program. I place the efforts of Thunder Valley CDC in the context of their community, the Pine Ridge Reservation of the Lakota People, and within an historical and contemporary context to highlight the implications of the efforts of Thunder Valley CDC. Using the theoretical frameworks of cultural revitalization and community economic development, I attempt to highlight two important components of Thunder Valley CDC's community development efforts - cultural revitalization for social healing, and development that emphasizes social, community and individual well-being. Thunder Valley CDC's Workforce Development through Sustainable Construction Program is still in its early stages, and so this first year of implementation very much represented a pilot phase. However, while specific successes are difficult to measure at this point, …

Not So Elementary: An Examination of Trends in a Century of Sherlock Holmes Adaptations

This study examines changes over time in 40 different Sherlock Holmes films and 39 television series and movies spanning from 1900 to 2017. Quantitative observations were mixed with a qualitative examination. Perceptions of law enforcement became more positive over time, the types of crime did not vary, and representation of race and gender improved over time with incrementally positive changes in the representation of queer, mentally ill, and physically handicapped individuals. The exact nature of these trends is discussed. Additionally, the trends of different decades are explored and compared. Sherlock Holmes is mostly used as a vehicle for storytelling rather than for the salacious crimes that he solves, making the identification of perceptions of crime in different decades difficult. The reasons for why different Sherlock Holmes projects were created in different eras and for different purposes are discussed.

Space Race: African American Newspapers Respond to Sputnik and Apollo 11 (open access)

Space Race: African American Newspapers Respond to Sputnik and Apollo 11

Using African American newspapers, this study examines the consensual opinion of articles and editorials regarding two events associated with the space race. One event is the Soviet launch of Sputnik on October 4, 1957. The second is the Apollo 11 moon landing on July 20, 1969. Space Race investigates how two scientific accomplishments achieved during the Cold War and the civil rights movement stimulated debate within the newspapers, and that ultimately centered around two questions: why the Soviets were successful in launching a satellite before the US, and what benefits could come from landing on the moon. Anti-intellectualism, inferior public schools, and a lack of commitment on the part of the US government are arguments offered for analysis by black writers in the two years studied. This topic involves the social conditions of African Americans living within the United States during an era when major civil rights objectives were achieved. Also included are considerations of how living in a "space age" contributed to thoughts about civil rights, as African Americans were now living during a period in which science fiction was becoming reality. In addition, this thesis examines how two scientific accomplishments achieved during this time affected ideas about education, …

"According to Their Wills and Pleasures": The Sexual Stereotyping of Mormon Men in American Film and Television (open access)

"According to Their Wills and Pleasures": The Sexual Stereotyping of Mormon Men in American Film and Television

This thesis examines the representation of Mormon men in American film and television, with particular regard for sexual identity and the cultural association of Mormonism with sexuality. The history of Mormonism's unique marital practices and doctrinal approaches to gender and sexuality have developed three common stereotypes for Mormon male characters: the purposeful heterosexual, the monstrous polygamist, and the self-destructive homosexual. Depending upon the sexual stereotype in the narrative, the Mormon Church can function as a proponent for nineteenth-century views of sexuality, a symbol for society's repressed sexuality, or a metaphor for the oppressive effects of performing gender and sexuality according to ideological constraints. These ideas are presented in Mormon films such as Saturday's Warrior (1989) as well as mainstream films such as A Mormon Maid (1917) and Advise and Consent (1962).

Re-examining the Battle of the Bulge : Assessing the Role of Strategic Intelligence and Coalition Warfare Against the 1944 Wehrmacht (open access)

Re-examining the Battle of the Bulge : Assessing the Role of Strategic Intelligence and Coalition Warfare Against the 1944 Wehrmacht

The 1944 German Ardennes offensive failed. It was overly ambitious, built on erroneous assumptions, insufficiently supported by logistics, and depended on the weather for success. Yet, the offensive achieved more than it should have given the strength and combat experience of the Allied armies in Europe. Previous attempts to explain the limited success of the German offensive have emphasized the failure of Allied strategic intelligence - Ultra. Intelligence is an accurate, but incomplete explanation for initial German success in the Ardennes. Three conditions allowed the Wehrmacht, approaching its manpower and logistical end, to crush the US First Army. First, coalition warfare so weakened the First Army that it became vulnerable to attack. Second, the Allies failed to develop a unified intelligence network capable of assessing the information that indicated the timing and target of the German attack. Finally, a well-executed German security and deception plan surprised the Allies. The well-executed German offensive manipulated both Allied intelligence and the Anglo-American coalition.

Edvard Munch's Fatal Women: A Critical Approach (open access)

Edvard Munch's Fatal Women: A Critical Approach

This study is the first comprehensive analysis of the fatal woman motif in the writings and art of Edvard Munch from the early 1890s to 1909. It uses a background of the women in the artist's life as well as the literary and artistic worlds in which Munch participated. Following separate accounts of Munch's relationships with five women, the manner in which the artist characterizes each as a fatal woman in his writings and art is discussed and analyzed. Next, the study describes the fatal woman motif in late nineteenth century art and literature. It begins with a discussion of the origin of the Symbolist and Decadent Movements and an ideological examination of the fatal woman motif as it is manifested in the writing and art of these two groups. In addition, it compares Munch's visual manifestations of the femme fatale with the manner in which the artist's contemporaries depicted her. Finally, this study describes two groups of men with whom Munch was particularly close: the Christiania Bohéme and the Schwarzen Ferkel Circle. An examination of the literary works of these men helps to determine the way in which they affected Munch's pictorial perception of the fatal woman.

National Patterns and Community Impacts of Major Domestic U.S. Military Base Closures, 1988-present (open access)

National Patterns and Community Impacts of Major Domestic U.S. Military Base Closures, 1988-present

This thesis analyses major U.S. military bases closed by the Base Realignment and Closure (BRAC) Commission since 1988. The study focuses on geographic patterns of pre-existing versus BRAC bases, statistical attributes, environmental restoration, and reuse of bases. Comparative case studies supplement the analysis, highlighting rural versus urban location, success versus failure, politics, conflict, and local versus national goals. Thesis findings are that: 92 bases closed versus 97 commonly published; a fairly even national closure pattern occurred, indicating Commission efforts to achieve equity, except for three closure clusters indicating efforts to consolidate functions in some regions and leave others; base reuse, while commonly perceived negatively, has been positive in most cases; the BRAC process is becoming more efficient, such that allowed years between BRAC closure decisions and base closures should be reduced from six to three years to benefit both communities and the Defense Department.
