Vehicle Routing for Emergency EvacuationsPereira, Victor Caon 22 November 2013 (has links)
This dissertation introduces and analyzes the Bus Evacuation Problem (BEP), a unique Vehicle Routing Problem motivated both by its humanitarian significance and by the routing and scheduling challenges of planning transit-based, regional evacuations. First, a variant where evacuees arrive at constant, location-specific rates is introduced. In this problem, a fleet of capacitated buses must transport all evacuees to a depot/shelter such that the last scheduled pick-up and the end of the evacuee arrival process occurs at a location-specific time. The problem seeks to minimize their accumulated waiting time, restricts the number of pick-ups on each location, and exploits efficiencies from service choice and from allowing buses to unload evacuees at the depot multiple times. It is shown that, depending on the problem instance, increasing the maximum number of pick-ups allowed may reduce both the fleet size requirement and the evacuee waiting time, and that, past a certain threshold, there exist a range of values that guarantees an efficient usage of the available fleet and equitable reductions in waiting time across pick-up locations. Second, an extension of the Ritter (1967) Relaxation Algorithm, which explores the inherent structure of problems with complicating variables and constraints, such as the aforementioned BEP variant, is presented. The modified algorithm allows problems with linear, integer, or mixed-integer subproblems and with linear or quadratic objective functions to be solved to optimality. Empirical studies demonstrate the algorithm viability to solve large optimization problems. Finally, a two-stage stochastic formulation for the BEP is presented. Such variant assumes that all evacuees are at the pick-up locations at the onset of the evacuation, that the set of possible demands is provided, and, more importantly, that the actual demands become known once buses visit the pick-up locations for the first time. The effect of exploratory visits (sampling) and symmetry is explored, and the resulting insights used to develop an improved formulation for the problem. An iterative (dynamic) solution algorithm is proposed. / Ph. D.

Vom Narren zum Gralskönig : Die Bedeutung der minne für Parzivals EntwicklungCasanova, Laura January 2011 (has links)
From an ingenious fool to the Grail King: the significance of courtly love in Wolfram’s Parzival The focus of this thesis lies on the doctrines in courtly behavior, a multifaceted system of chivalric norms and behaviors often referred to as the knightly virtue system based on the literature of the early and high Middle Ages. The aim of this thesis is to study the different aspects, such as religious, military, courtly and romantic, of the knightly virtue system. The romantic aspect of the knightly ideal is given particular attention, as it is the focus of this paper. The word minne is the bearer of the romantic aspect and is central in Wolfram’s von Eschenbach Parzival which is the main source studied. The following issues are discussed in more detail: how the knightly ideal is presented in Wolfram’s epic and to what extent the minne affects the development of Parzival to the Grail king. In the course of this thesis it will also be shown that the romantic aspect is the most influential aspect of the knightly virtue system and that this particular aspect truly defines an ideal knight.

Gluck's "Armide" and the creation of supranational operaSmith, Annalise 25 November 2010 (has links)
Christoph Willibald Gluck’s opera Armide (1777) is an anomaly within the context of his eighteenth-century operatic reform. While all of Gluck’s other libretti had been written as an embodiment of the operatic reform, including his Italian works Orfeo ed Euridice (1762) and Alceste (1767) in addition to the French operas Iphigénie en Aulide (1774) and Iphigénie en Tauride (1779), Armide was based upon the seventeenth-century libretto that Phillipe Quinault had written for Jean-Baptiste Lully, the founder of French tragédie lyrique. The use of Quinault’s libretto drew a direct comparison not only between Gluck and Lully, but also between Gluck and traditional French opera. Setting Armide also required Gluck to incorporate many traditional elements of tragédie lyrique absent in the operatic reform, such as divertissement and ballet. Armide’s departure from the tenets of the reform were so significant that they were criticized by Gluck’s French librettist François-Louis Gand LeBland Du Roullet, who found particular fault with the opera’s lack of dramatic veracity.
It is the very incongruity of Armide—its utilization of an antiquated libretto—that makes it key to understanding Gluck’s conception of eighteenth-century opera. Armide provides the best opportunity to explore how Gluck amalgamated the traditional forms and styles of French opera with the goals of Viennese operatic reform. Drawing out connections between tragédie lyrique and the precepts of his reform, Gluck demonstrated the composer’s role in strengthening and clarifying the reform qualities as expressed by the libretto. Through musical analysis, this thesis demonstrates that Armide maintains the musical characteristics and dramatic musical construction of Gluck’s earlier reform operas. It also illustrates that while Gluck honoured Lully’s conception of tragédie lyrique, he did not hesitate to improve what he saw as the faults of the earlier operatic style. Gluck’s juxtaposition of the Italian and French operatic traditions in Armide elucidates his creation of supranational opera. Superseding and encompassing both the French and Italian national styles, Gluck enlivened the operatic traditions of both countries while remaining true to his own dramatic and musical conception of opera.

Sequence Stratigraphy of the Bridal Veil Falls Limestone, Carboniferous, Lower Oquirrh Group, on Cascade Mountain, Utah: A standard Morrowan Cyclostratigraphy for the Oquirrh BasinShoore, David Joseph 21 March 2005 (has links) (PDF)
The Bridal Veil Falls Limestone (lowest 400 meters of the Permo-Carboniferous Oquirrh Group) is well exposed on the flanks of Cascade Mountain (Wasatch Front and adjacent mountain ranges) near Provo, Utah. Because of its excellent exposure and location in the heart of the Oquirrh depocenter, this area was selected to develop a sequence stratigraphic framework for Morrowan rocks that may be applied throughout the Oquirrh basin (NW Utah and southern Idaho) as well as the adjacent Ely and Bird Springs troughs. Eleven partial to complete sections of the Bridal Veil Falls Limestone were measured along the west and north flanks of Cascade Mountain and the south end of Mt. Timpanogos. There the limestone is comprised principally of mud-rich carbonate lithofacies punctuated by thin, and sometimes discontinuous quartzose sandstone beds. The predominance of muddy to grain-rich heterozoan limestone microfacies suggests deposition on a west-dipping low energy carbonate ramp that prograded westward throughout Morrowan time. Sandstones reflect transport of siliciclastics from the incipient Weber shelf (located to the NE) during episodes of sea-level lowstand. The Bridal Veil Falls Limestone is subdivided into 21, third and fourth order depositional sequences ranging in thickness from 3 to 60 meters, and 62 parasequences. Parasequences are commonly asymmetrical, reflecting rapid flooding followed by protracted shoaling and/or sea level drop. Selected cycles are recognized in the Lake Mountains, Thorpe Hills, and the southern Oquirrh Mountains to the west of Cascade Mountain indicating that Parasequences delineated at Cascade Mountain are regionally extensive over an area of at least 300 square kilometers.

Technik und Bildung in der verwissenschaftlichten LebensweltLumila, Minna 02 June 2023 (has links)
Die Studie versucht, Husserls Modell einer nicht-wissenschaftlichen Lebenswelt für pädagogische Untersuchungen zum Verhältnis von Technik und Bildung in der verwissenschaftlichen Welt zu öffnen. Sie diskutiert Entwicklungsprobleme der Spätmoderne unter pluralen Fragestellungen und führt Ansätze und Traditionen zusammen, die unterschiedliche Wege zur Weiterentwicklung der modernen Bildungstheorie beschritten haben. Im Zentrum steht die Frage, wie moderne Technik einerseits als lebensweltliche Entfremdung des Menschen problematisiert und andererseits als Produkt menschlicher Freiheit und Weltgestaltung gewürdigt werden kann. In vier Kapiteln werden die methodischen Ansätze und Antworten vorgestellt, die der Philosoph und Pädagoge Eugen Fink (1905–1975), der Philosoph Martin Heidegger (1889–1976), der Philosoph und Erziehungswissenschaftler Theodor Litt (1880–1962) und der Soziologe Helmut Schelsky (1912–1984) auf die Frage nach dem Verhältnis von Bildung und Technik gegeben haben. Im Durchgang durch ihre Positionen wird ein Konzert erarbeitet, dessen Originalität darin liegt, Abstimmungsprobleme von Bildung, Technik und Lebenswelt aus postdualistischer, praxistheoretischer sowie posthumanistischer Perspektive zu thematisieren. / The study attempts to open Husserl's model of a non-scientific lifeworld for pedagogical investigations of the relationship between technology and “Bildung” in the scientific world. It discusses developmental problems of late modernity under plural questions and brings together approaches and traditions that have taken different paths to the further development of modern “Bildungs”-theory. The central question is how modern technology can be problematized on the one hand as the alienation of human beings from the world of life and on the other hand be appreciated as a product of human freedom and the shaping of the world. Four chapters present the methodological approaches and answers that philosopher and educator Eugen Fink (1905–1975), philosopher Martin Heidegger (1889–1976), philosopher and educationalist Theodor Litt (1880–1962), and sociologist Helmut Schelsky (1912–1984) have given to the question of the relationship between education and technology. In the course of their positions, a concert will be developed whose originality lies in addressing the coordination problems of “Bildung” (education), “Technik” (technology) and “Lebenswelt” (lifeworld) from a post-dualist, praxis-theoretical as well as post-humanist perspective.
