Modeling and simulation have become fully ingrained into the set of design and development tools that are broadly used in the field of power electronics. To state simply, they represent the fastest and safest way to study a circuit or system, thus aiding in the research, design, diagnosis, and debugging phases of power converter development. Advances in computing technologies have also enabled the ability to conduct reliability and production yield analyses to ensure that the system performance can meet given requirements despite the presence of inevitable manufacturing variability and variations in the operating conditions. However, the trustworthiness of all the model-based design techniques depends entirely on the accuracy of the simulation models used, which, thus far, has not yet been fully considered. Prior to this research, heuristic safety factors were used to compensate for deviation of real system performance from the predictions made using modeling and simulation. This approach resulted invariably in a more conservative design process. In this research, a modeling and design approach with parametric and model-form uncertainty quantification is formulated to bridge the modeling and simulation accuracy and reliance gaps that have hindered the full exploitation of model-based design techniques. Prior to this research, a few design approaches were developed to account for variability in the design process; these approaches have not shown the capability to be applicable to complex systems. This research, however, demonstrates that the implementation of the proposed modeling approach is able to handle complex power converters and systems. A systematic study for developing a simplified test bed for uncertainty quantification analysis is introduced accordingly. For illustrative purposes, the proposed modeling approach is applied to the switching model of a modular multilevel converter to improve the existing modeling practice and validate the model used in the design of this large-scale power converter. The proposed modeling and design methodology is also extended to design optimization, where a robust multi-objective design and optimization approach with parametric and model form uncertainty quantification is proposed. A sensitivity index is defined accordingly as a quantitative measure of system design robustness, with regards to manufacturing variability and modeling inaccuracies in the design of systems with multiple performance functions. The optimum design solution is realized by exploring the Pareto Front of the enhanced performance space, where the model-form error associated with each design is used to modify the estimated performance measures. The parametric sensitivity of each design point is also considered to discern between cases and help identify the most parametrically-robust of the Pareto-optimal design solutions. To demonstrate the benefits of incorporating uncertainty quantification analysis into the design optimization from a more practical standpoint, a Vienna-type rectifier is used as a case study to compare the theoretical analysis with a comprehensive experimental validation. This research shows that the model-form error and sensitivity of each design point can potentially change the performance space and the resultant Pareto Front. As a result, ignoring these main sources of uncertainty in the design will result in incorrect decision-making and the choice of a design that is not an optimum design solution in practice. / Ph.

Vehicle accidents by means of Public transport annually leads to a large number of passenger deaths and life long disablement. AsDu Toit, Martina Petronella a result, there is a need for preventative measures by identifying the psychomotor abilities of bus drivers during the recruitment and selection process of employment. The study was conducted among 398 bus drivers employed by a large bus company. The Vienna Test Battery was administered. It was found that distance estimation, ability to recognize forms and figures, concentration ability, eye-hand feet coordination and two-hand coordination predicted the effectiveness of bus drivers successfully. It is suggested that further research should focus on client services, attitude of bus drivers and learning potential, as factors that influence the effectiveness of bus drivers. / Industrial psychology / M.A. (Industrial Psychology)

L’étude de la voirie antique du site archéologique de Saint-Romain-en-Gal (Rhône), menée depuis vingt-cinq ans, a permis de mettre en lumière le rôle essentiel de la rue du Portique dans le développement de ce quartier de Vienne antique, situé sur la rive droite du Rhône. Traversant la plaine d’ouest en est, cette rue qui s’interrompait brutalement sur la berge du Rhône en face du cœur ancien de la capitale des Allobroges, a soulevé la question du franchissement du fleuve. Le nombre des ponts attribués à l’époque romaine a connu des évolutions au fil du temps. Une recherche historiographique importante a donc été menée afin d’établir la connaissance effective des indices prouvant la présence d’un ou de plusieurs ouvrages d’art antiques à la hauteur de Vienna, duplex urbs. Mais pour comprendre leur logique d’implantation, il a fallu également suivre la genèse d’installation des points de franchissement plus récents qui ont été soumis aux mêmes contraintes topographiques et urbaines que les ouvrages antiques. Il ressort de cette étude que deux ponts peuvent être attribués à l’époque romaine. Le troisième, plus monumental, le pont de pierre, considéré dans la mémoire collective comme le Pont Romain de la ville, semble toutefois remonter au Haut Moyen Âge. / The study of the ancient road to the archaeological site of Saint-Romain-en-Gal (Rhône), conducted for twenty-five years, helped to highlight the essential role of the Portico street in the development of this area of Antique Vienna, on the right bank of the Rhône. Across the plain from west to east, the street would strop abruptly on the bank of the Rhône opposite the ancient heart of the capital of the Allobroges, raised the issue of crossing the river. The number of bridges attributed to the Roman era has seen changes over time. An important historiographical research has been conducted to determine actual knowledge clues proving the presence of one or more works of ancient art at the height of Vienna, duplex urbs. But to understand their logic implementation, it took also follow the genesis of installing newer crossing points that were subject to the same topographical and urban and ancient books constraints. It appears from this study that two bridges can be attributed to the Roman era. The third, more monumental, stone bridge, seen in the collective memory as the roman bridge in the city, however, seems to go back to the High Middle Age.

The purpose of the present study was to determine the concurrent validity of learning potential and psychomotor ability measures for the prediction of haul truck operator (N=128) performance in an open-pit mine. Specific aims were to determine the nature of the relationship between learning potential and psychomotor ability; whether there are higher order cognitive or psychomotor factors present in the combined use of the TRAM 1 and Vienna Test System measures; and the relative contribution of learning potential and psychomotor ability in the prediction of haul truck operator performance. The validity of learning potential and psychomotor ability measures was partially supported. A positive correlation between general (cognitive) ability (g) and psychomotor ability was reported. Factor analysis provided relatively consistent evidence for a general (cognitive) ability factor (g) underlying performance on all measures. The relative contribution of learning potential and psychomotor ability in the prediction of performance could not be established. / Industrial and Organisational Psychology / M. Com.

L’Empire austro-hongrois (1867-1918) est l’un des derniers empires d’Europe à s’être effondré avec la fin de la Première Guerre mondiale. Cas particulièrement en accord avec les conditions internes de la politique et de l’économie austro-hongroise, l’apparition du phénomène social du dandysme à Vienne au début du XXe siècle est le centre de ce travail de mémoire. La figure sociale du dandy, remarquablement moderne, est étudiée en suivant la conceptualisation idéal-typique, héritage de Max Weber. En suivant les écrits sociologiques de Karl Marx, Max Weber et Robert Michels, le portrait typique des quatre figures socio-économiques que sont tour à tour la figure du bourgeois, du prolétaire, du bohème et de l’aristocrate, permettent, dans une première partie du mémoire (chapitre deux), de délinéer conceptuellement la figure du dandy. Une fois cet outil forgé, il est possible d’y comparer la réalité viennoise, avec le cas de Stefan Zweig, pour en montrer les particularités. L’apparition du dandy à la fin de la monarchie des Habsbourg n’est pas étrangère à plusieurs conditions externes que portent en soi cette première partie du XXe siècle, marquée notamment par le nationalisme et la Première Guerre mondiale. Les conditions économiques que permettent aussi l’expression littéraire et journalistique témoigne de cette phénoménalisation sociale à laquelle participe le dandy et sont discutées dans la deuxième partie du mémoire (chapitre trois). En basant cette étude sur le phénomène du dandy, le présent travail s’emploie à appréhender ce phénomène au travers d’une biographie sociologique de l’écrivain et poète Stefan Zweig. Au cours des chapitres quatre et cinq, la mise en relief de la biographie de Stefan Zweig rencontrera son écho social, entre l’étude de l’homme, de l’œuvre, de la vie et des différentes caractéristiques propres au dandy. Enfin, il sera présenté au cinquième chapitre, l’influence de l’esthétique et de la philosophie sur la conduite de vie du dandy, guidé notamment par la philosophie de Friedrich Nietzsche, et l’importance des valeurs du pacifisme et du cosmopolitisme, sous l’influence de la religion juive. En conclusion, je reviens sur l’idéal-type du dandy et m’interroge son utilité pour appréhender des phénomènes contemporains. / The Austro-Hungarian Empire (1867-1918) is one of the last European Empire to collapse with the end of World War One. Tightly linked with internal conditions such as Austro- Hungarian politics and economics, the central theme of this work concerns the emergence of the social phenomenon of dandysm in Vienna at the beginning of the XXth century. Remarquably modern, the social figure of the dandy is studied following the ideal-typical method, a legacy of Max Weber. Following the sociological writings of Karl Marx, Max Weber, and Robert Michels, the typical portrait of the four socio-economic figures such as the bourgeois, the proletarian, the bohemian and the aristocrat allows, in the first part of the thesis (chapter two), to show the features and to conceptually delineate the figure of the dandy. Once this portrait is forged, it is possible to compare the Viennese reality with the case of the poet Stefan Zweig. The appearance of the dandy, at the end of the Habsburg monarchy, is not alien to many external conditions that are themselves particularly linked to this first part of the XXth century, marked notably by nationalism and World War I. Discussed in the second part of the thesis (chapter three), the economic conditions, that are expressed with either literature or journalism, reflect this social phenomenalization in which the dandy takes part. The study of the social appearance of the dandy being at the very center of this study, the present thesis seeks to understand this phenomenon through a sociological biography of the writer and poet Stefan Zweig. In the fourth and fifth chapter, highlights of his biography meet its social resonance with dandysm through the man itself, his work, his life and the way he lived it. Finally, the influence of aesthetics and philosophy on dandy’s life, especially following Friedrich Nietzsche’s very own word and ideas, will be presented as well as the importance of values of pacifism and cosmopolitism, as influences of Jewish religion. In conclusion, I return to the ideal- type of dandy by questioning its usefulness in understanding contemporary phenomena. / Die Österreichisch-Ungarische Monarchie (1867-1918) war eines der letzten europäischen Reiche, welches mit dem Ende des Ersten Weltkrieges kollabierte. Eng verbunden mit wirtschaftlichen und politischen Bedingungen des k.u.k. Österreichs, handelt das zentrale Thema dieser Arbeit von der Entstehung der sozialen Phänomene rund um den Dandyismus in Wien zu Beginn des zwanzigsten Jahrhunderts. Die soziale Figur des Dandy wird nach dem idealtypis- chen Konzept Max Webers untersucht. Anlehnend an die soziologischen Schriften von Karl Marx, Max Weber und Robert Michels, dem typischen Porträt der vier sozioökonomischen Zahlen, wie der Bürger, der Proletarier, die Boheme und der Aristokrat gestatten, dass im ersten Teil der Abschlussarbeit (Kapitel zwei) die Figur des Dandys konzeptionell beschrieben wird. Auf dieses Porträt aufbauend wird es möglich, die herausgearbeiteten Merkmale mit der Wiener Realität zu vergleichen. Die Texte des Dichters Stefan Zweig geben dazu genug Material. Das Aussehen des Dandys am Ende der Habsburgermonarchie ist passend zu vielen äußeren Bedin- gungen, die besonders mit dem ersten Teil des zwanzigsten Jahrhunderts verbunden sind. Speziell werden diese vom Nationalismus und dem Ersten Weltkrieg beeinflusst. Im zweiten Teil der Abschlussarbeit (Kapitel drei) werden die wirtschaftlichen Bedingungen, die entweder mit Literatur oder Journalismus zum Ausdruck kommen, und die die soziale phenomenalization vom Dandy wiederspiegeln, beleuchtet. Die Untersuchung der sozialen Erscheinung des Dandy dient als Basis dieser Studie. Die vorliegende Arbeit versucht, das Phänomen des Dandyismus durch eine soziologische Biographie des Schriftstellers und Dramatikers Stefan Zweig zu verstehen. In den Kapiteln vier und fünf treffen die Höhepunkte seiner Biographie die gesellschaftliche Reso- nanz des Dandyismus auf den Mensch selbst, seine Arbeit, sein Leben und seine Lebensart. Schlussendlich wird der Einfluss von Ästhetik und Philosophie auf das Leben eines Dandy vor allem nach den Worten und Ideen von Friedrich Nietzsche präsentiert, sowie die Bedeutung der Werte des Pazifismus und Kosmopolitismus, als auch Einflüsse der jüdischen Religion. Ich kehre zum Idealtyp des Dandys zurück, indem ich seine Nützlichkeit in gegenwärtigen Phänomenen in Frage stelle.

107 Summary The Ozone layer of the Earth located in the stratosphere in an altitude of 20 to 50 kilometres is the important part of the gases surrounding the planet Earth. Its purpose is to absorb UV radiation that otherwise very negatively affects life on the Earth. During the twentieth century, this ability was weakened by the emission of substances proven much later to be very dangerous in this way. Until 1987, by various chemical reactions, in particular of chlorine atoms, the ozone hole has been formed over the South Pole of the Earth, not fully healed yet. In 1985, risk to human life led using the precautionary principle to the adoption of the Vienna Convention and subsequently of its implementing protocol including specific obligations especially the control measures of the production and consumption of ozone depleting substances and of the trade with them in 1987. The protocol was later modified by amendments and adjustments. This diploma thesis describes these acts with respect to their evolution and actual state of knowledge. At European level, it shows the evolution of the European environmental law in focus on the protection of the ozone layer and on the process of incorporation of international instruments in this area of environmental law. It describes these European acts and compares the...

Le personnage s'inscrit dans l'histoire de la seconde Maison de Vienne (depuis le milieu du XIIIe siècle), issue des comteséponymes, peu étudiée. Les diverses branches furent animées par quelques personnagesprestigieux, comme Jean de Vienne, amiral de France. Trois faits : la mort de l'amiral(Nicopolis, 1396), le fabuleux héritage de son frère Huguenin, et une robuste santé, permirentà Guillaume de s'affirmer comme "chef " de la Maison de Vienne. Il se distingua par unservice multiforme (militaire, diplomatique, de conseil) auprès des ducs de BourgognePhilippe le Hardi, Jean sans Peur et Philippe le Bon, de 1379 à sa mort, et par une gestionavisée de son immense patrimoine terrien, dans le Duché (presque toute la Bresselouhannaise ; Arc-en-Barrois ; sans doute le premier revenu domanial duchois), et dans leComté, auquel il faut ajouter deux hôtels, à Dijon et à Paris. Olivier de La Marche propagea larenommée de Guillaume de Vienne "le Grand" et "le Sage". Ses deux épouses successives lefirent entrer dans des familles prestigieuses : Thoire-Villars (alliée aux comtes de Genève) etles Dauphins d'Auvergne. Sur les champs de bataille et comme diplomate, le "sire de SaintGeorge" connut la gloire et la célébrité : de l'Ecosse à Mahdia (en l'actuelle Tunisie), de laNormandie à Milan, il s'affirma comme un haut cadre de l'Etat bourguignon en gestation.Comblé d'honneurs par les Ducs ( ordre de l'Arbre d'or en 1403, premier nommé chevalier del'ordre de la Toison d'or en 1430), recevant la plus forte pension ( 3000 francs/an), intime deces souverains, il fut aussi un membre actif du Grand conseil royal et gouverneur des deuxBourgognes ; il s'illustra à la croisade (Mahdia, 1390), au service de l'Eglise (familier deClément VII ; chef de l'ambassade bourguignonne au concile de Constance (1415) ;bienfaiteur de Colette de Corbie pour la fondation de plusieurs couvents) et fut le dernierBourguignon auquel s'adressa Jean sans Peur sur le pont de Montereau (1419). Sa secondeépouse lui donna un fils, lui aussi prénommé Guillaume, et seigneur de Saint-Georges et deSainte-Croix à la mort de son père – ce qui a posé problème à plus d'un historien. Cepersonnage, pourvu d'une solide formation, militaire mais aussi intellectuelle (envoyé en"Allemagne" pour y apprendre la langue), connut une foudroyante ascension, du vivant de sonpère, au service de Jean sans Peur puis de Philippe le Bon. Non moins foudroyante fut, dès1440, la dilapidation du patrimoine mobilier et immobilier du "sire de Saint-George" par lenouveau Guillaume de Vienne et son fils Jean, lesquels menèrent, semble-t-il, une viedissolue, et tombèrent dans les rets de multiples profiteurs, au premier chef les "légistes etgens de finances". Marguerite de Vienne, une soeur de Jean, fut bien près d'épouser le comted'Eu, beau-frère de Philippe le Bon. Elle s'unit à Rodolphe de Hochberg, issu d'une puissantefamille de Forêt Noire, et devenu comte de Neuchâtel en succession de son cousin Jean,comte de Fribourg et maréchal de Bourgogne. Marguerite et Rodolphe unirent leurs efforts etparvinrent à reconstituer une bonne partie du patrimoine seigneurial de "Guillaume de Viennele Grand", qu'ils transmirent à leur fils Philippe, célèbre par ses états de service auprès deCharles le Téméraire puis de Louis XI. La fille de Philippe, Jeanne de Hochberg, par sonmariage apporta l'héritage à la famille d'Orléans-Longueville. D'autres branches "Vienne"s'éteignirent, mais une semblable étude permettrait de sortir de l'ombre des personnages decette Maison, comme Guillaume de Vienne, seigneur de Montby et de Montbis (décédé en1471), les Vienne seigneurs de Listenois (Bourbonnais), sans oublier Girard (mort en 1545),seigneur de Commarin, fondateur de la chapelle de Vienne en la Sainte-Chapelle de Dijon. / The character fits into the history of the Second House Vienna (since the mid-thirteenth century), from the countseponymous little studied. The various branches were animated by some famous characterslike Jean de Vienne, admiral of France. Three facts: the death of Admiral (Nicopolis, 1396),the fabulous legacy of his brother Huguenin, and robust health, allowed William to assertitself as "leader" of the House of Vienna. He distinguished himself by service multiforme(military, diplomatic, counseling) from the Dukes of Burgundy, Philip the Bold, John theFearless and Philip the Good, from 1379 to his death, and by careful management of hisimmense estates with the Duchy (almost all Bresse louhannaise; Arc-en-Barrois, probably thefirst Income duchois lands), and the county, which must be added two hotels in Dijon andParis. Olivier de la Marche spread the fame of Guillaume de Vienne "Grand" and "wisdom."His two successive wives brought him into prestigious families: Thoire-Villars (allied to theCounts of Geneva) and Dolphins Auvergne. On the battlefield and as a diplomat, the "lord ofSaint George" achieved fame and stardom: from Scotland to Mahdia (in present-day Tunisia),from Normandy to Milan, he established himself as a high part of the Burgundian State ingestation. Loaded with honors by the Dukes (order of the Golden Tree in 1403, the firstknight of the Order of the Golden Fleece in 1430), receiving the highest pension (3000 francs/ year), intimate the sovereign, he was also an active member of the Grand Council of Royaland Governor of the two Burgundies, he distinguished himself in the Crusades (Mahdia,1390), in the service of the Church (familiar Clement VII head of the embassy Burgundy theCouncil of Constance (1415), benefactor of Colette of Corbie to the founding of severalmonasteries) and was the last Bourguignon which John the Fearless spoke on the bridge ofMontereau (1419). His second wife bore him a son, also named William, and lord of Saint-Georges and St. Croix in the death of his father - which was a problem in more than onehistorian. This character provided a solid background, but also military intellectual (sent in"Germany" to learn the language), had a startling rise in the lifetime of his father, in theservice of John the Fearless and Philip the Good. No less startling was from 1440, thesquandering of movable and immovable property of the "Comte de Saint-George" the newGuillaume de Vienne and his son John, who led, it seems, a dissolute life, and fell into thesnares of multiple riders, primarily the "forensic people and finances." Vienna Marguerite,sister of John, was very close to marrying the Count of Eu, brother of Philip the Good. Shejoins Rudolph Hochberg, from a powerful family in the Black Forest, and became Count ofNeuchâtel in succession to his cousin John, Count of Burgundy and Marshal of Fribourg.Marguerite and Rudolf joined forces and managed to rebuild much of the stately heritage"Guillaume Grand Vienna", they transmitted to their son Philippe, famous for his service toCharles the Bold and Louis XI. Philippe's daughter, Jeanne de Hochberg, by his marriagebrought the family legacy of Orleans-Longueville. Other branches "Vienna" went out, butsuch a study would emerge from the shadows of the characters in this House, as Guillaume deVienne, lord of Montby and Montbis (d. 1471), the Vienna lords Listenois (Bourbonnais),without forgetting Girard (d. 1545), lord of Commarin, founder of the Vienna Chapel of theSainte-Chapelle in Dijon

This diploma thesis investigates propaganda practices of the Czechoslovakian Ministry of Foreign Affairs applied especially to the local press of Vienna during the interwar period. The aim of the thesis is to explain the reasons that made the Czechoslovakian authorities take these steps and to reconstruct the events surrounding the subsidizing of the Vernay publishing house. A part of the investigation is an analysis of the press published under this house (Der Tag, Die Stunde, Die Börse, Die Bühne, Die Sphinx and business books of Compass) - its history, political orientation, columns, journalists, characteristics, etc. The emphasis is placed on changes brought by the Czechoslovakian influence. The thesis studies activities of the journalists (not only in Vernay's newspapers) during the crucial moments of the history of the Austrian - Czechoslovakian relations (e.g. the Austro-German Customs Union of 1931) and then draws conclusions on the effectiveness the propaganda. In this regard, the aspects seen as the most problematic are especially the non-loyalty of some of the journalists, a wide awareness of the propaganda in both countries, and a choice of newspapers intended for the purpose of propaganda.
