A Study of the Problems of College Freshmen and the Effects of one Semester of College Attendance on Those Problems

Reeder, Thelma A. 08 1900 (has links)
"The problem of this study is to determine, by means of a statistical analysis of the results from the Mooney Problem Check List given to 1011 students at North Texas State College during the year 1949-50, what the problems of college freshmen are and if there is a significant change in the areas in which those problems are found from one semester to another."--1-2.

Komplexe Kontakt- und Materialmodellierung am Beispiel einer Dichtungssimulation

Nagl, Nico 08 May 2014 (has links)
In vielen industriellen Anwendungen sind Dichtungen im Einsatz. Vergleicht man den Preis mit dem eines Gesamtsystems, in denen Dichtungen verwendet werden, so sind Dichtungen verhältnismäßig günstig. Jedoch führt ein Versagen von Dichtungen meist zu schwerwiegenden Konsequenzen. Dichtungen sind komplexe Subsysteme und ihre Auslegung erfordert umfangreiche Kenntnisse im Bereich Materialmodellierung, Belastung und Versagenskriterien. Die heutige Simulationstechnologie ermöglicht einen parametrischen Workflow für die Berechnung des Verhaltens von Dichtungen mit den auftretenden Effekten wie nichtlinearem Materialverhalten, wechselnden Kontaktbedingungen und Flüssigkeitsunterwanderung bei Druck. Als ein führendes Simulationswerkzeug für diese physikalische Fragestellung wird ANSYS Mechanical für die Auslegung herangezogen. Desweiteren kann das Verständnis für das Produkt erhöht werden, was zu einer Verbesserung der Funktionalität und der Zuverlässigkeit führt. Versuchsdaten können als Spannungs-Dehnungskurven in ANSYS importiert werden, welche das Materialverhalten des hyperelastischen Werkstoffs mit traditionellen Materialmodellen wie Mooney Rivlin, Ogden and Yeoh oder einer neueren Formulierung, der Antwortfunktionsmethode, widerspiegeln. Robuste Kontakttechnologien beschleunigen die Simulation und Entwicklungszeit-Berechnungszeiten und gewährleisten ein genaues Verhalten des Simulationsmodells. Insbesondere bei Dichtungen ist die druckbeaufschlagte Fläche in 2D und 3D Anwendungen von Bedeutung. ANSYS berechnet diese automatisch in Abhängigkeit des aktuellen Kontaktzustandes. Diese benutzerfreundliche Unterstützung führt zu einer höheren Genauigkeit des Simulationsergebnisses, da ein manuelles Schätzen der Druckflächen entfällt. Mit einem parametrischen und durchgängigen Ansatz innerhalb von ANSYS Workbench, beginnend bei der CAD-Geometrie, über die Vernetzung, Material- und Randbedingungsdefinition und Lösung. können eine Reihe von Varianten in kurzer Zeit berechnet werden. Neben einem besseren Verständnis für das Produkt hilft dies dem Ingenieur Änderungen vorzunehmen, was zu exakten und aussagekräftigen Ergebnissen führt. Desweiteren kann der Einfluss von Unsicherheiten berücksichtigt werden, sodass der Berechnungsingenieur fernab von idealen Bedingungen robuste und zuverlässige Dichtungen entwickeln kann.

Towards Christianity without authority : pluralism, skepticism, and ecclesiastical power in selected examples of humorous Newfoundland writing

Fralic, Michael Lloyd 02 February 2007
In recent decades in Newfoundland, a sustained interest in Christian symbols, stories, and values has been paired with increasing criticism of Christian religious institutions and agents. Newfoundlands burgeoning tradition of professional humour has reflected this changing set of relationships to Christianity. This robust young humour tradition richly reflects the ongoing pluralization and secularization of Newfoundland culture, and abundantly exemplifies humours distinctive potential as a means of addressing potentially contentious or vexing issues. Yet, surprisingly, literary criticism has almost entirely avoided the prominent stream of Newfoundland humour that addresses the islands religious legacy.<p>This project aims to begin to correct this substantial critical omission, examining points of continuity among a number of works produced over the past four decades. It focuses on the works embrace of political and/or epistemological pluralism, typically married to religious skepticism and to misgivings about conventional arrangements of religious power. Chapter One provides an historical and critical context for the project, introduces subsequent chapters, and speculates on ramifications of the pluralistic current that runs through the works in the study. Chapter Two examines religious jokes in Newfoundland joke books. It emphasizes the jokes overall tendency toward (an often ambiguous) religious conservatism, as well as the books latent pluralism regarding interdenominational relations. Chapter Three focuses on journalist and playwright Ray Guys often fierce satire of Christian religious agents and institutions. It argues that Guys satire utterly rejects the legitimacy of religious authority in the civic realm, largely on the grounds that transcendent truthfulness is often invoked as a means of justifying otherwise objectionable power. Chapter Four explores the ecumenical religious humour of columnist and memoirist Ed Smith. It focuses on Smiths playful efforts to harmonize Christian faith and practice with a measure of religious uncertainty presented as a necessary foundation for humane coexistence. Chapter Five examines Ed Kavanaghs novel The Confessions of Nipper Mooney. Primarily, it explicates and examines the novels liberal favouring of the individual moral conscience, and the symbolic association of its religiously dissident and/or marginalized protagonists with elements of the Catholic tradition. Chapter Six discusses Berni Stapletons comic play The Pope and Princess Di. The chapter emphasizes the plays presentation of symbols constant subjection to alteration and hybridization, and its cautious regard for valuable symbols (religious or otherwise) that nonetheless become destructive when viewed as sacrosanct.<p>Chapter Seven concludes the study by considering the works participation in political, philosophical, and literary/dramatic movements that problematize long-established religious modes and support a secular-pluralist outlook. It reflects on the role of humour in movements for change and on didacticism and popular humour as features of publicly engaged literature; it discusses other works of Newfoundland humour that approach religious matters from similarly secular, though less overtly political, angles; and it speculates on some social implications of the ascendancy of liberal, pluralistic values, considering these Newfoundland works in a more general Canadian cultural context.
