    Description: Especially pedestrians rely on the interaction with other road users. The introduction of automated driving systems withdraws this communication from drivers and thus, vehicles need to interact with pedestrians. Therefore, multiple vehicle-pedestrian-communication concepts are evaluated. A driver intention prediction allows pedestrians to learn these newly introduced signals, while driver and vehicle communicate simultaneously.

    Description: In 1923 Count Richard Coudenhove-Kalergi, offspring of an aristocratic family in the Austro-Hungarian Monarchy, published the book Paneuropa which was soon translated into almost all important languages of the world. A movement was launched under the same name and soon became the synonym for all efforts concerning the creation of a united Europe in the interwar period and even beyond. The Count was convinced of the necessity to create Paneurope the main reasons being the danger of a second world war, Bolshevist Russia and the economic power of the United States of America. Since 1925 Paneurope Unions were founded in nearly every European capital; the headquarter were Vienna (Hofburg). But the movement failed in mobilizing the masses. Coudenhove who was the embodiment of Paneurope was only in contact with statesmen, industrial leaders and intellectuals. His great merit was the confrontation of European governments with the idea of a united Europe, the rising of European question. Despite of all his efforts European politicians were not able to realize the importance of "United States of Europe" in those days. Nationalism was too strong and there seemed to be no willingness to give up parts of the own sovereignity and to develop a better understanding for democracy. The study presents a comprehensive view of the Paneuropean Movement during the interwar period including records of the Moskow Archive (captured material). It opens with a biographical sketch followed by the political program and how it was adapted to the political situation of those days; other main items are fund raising, financial organisation and propaganda. Also, there is an analysis of Paneurope in interaction with contemporary Austrian and European policies. Another chapter is dedicated to the ideas to unite Europe economically (since 1933) or on a cultural basis (saving the Abendland). The longitudinal views are completed by sectional views which focussed on the way how Coudenhove and his Paneurope Movement dealt with ideologies and mental streams of these days; They fought Bolshevism and since 1933 against National Socialism; they sympathized with Italian Fascism; Paneurope was anti-democratic and aristocratic. Some of the aims were revolutionary but many people regarded them as utopian. In comparison with the European Union there are certain parallels between European Union and Paneurope. Today we can see Paneurope - with restrictions - as an avant-garde of the European Union.
    Description: Im Jahr 1923 veröffentlichte der altösterreichische Graf Richard Coudenhove-Kalergi das Buch "Paneuropa", es wurde in fast alle Weltsprachen übersetzt und die gleichnamige Bewegung sollte alsbald das Synonym für sämtliche Europa-Vereinigungsbestrebungen in der Zwischenkriegszeit und darüber hinaus werden. Coudenhove sah in Paneuropa einen Weg, um einem weiteren Weltkrieg, der ideologischen Bedrohung durch die bolschewistische Sowjetunion und der großen amerikanischen Wirtschaftskonkurrenz entgegen zu treten. Ab 1925 entstanden in fast allen europäischen Hauptstädten sog. Paneuropa-Unionen, das Zentralbüro befand sich in der Wiener Hofburg. Paneuropa wurde nie eine Massenbewegung, Coudenhove, mit dem die Bewegung stieg und fiel, blieb auf der elitären Ebene der Politiker, Wirtschaftsfachmänner und Intellektuellen. Es war sein Verdienst, die europäischen Regierungen erstmals mit der Europafrage konfrontiert zu haben, wenngleich die damaligen Politiker nicht in der Lage waren, die Vereinigung des europäischen Kontinents zu bewerkstelligen. Zu stark waren die Staaten an ihre eigene Nation gefesselt sowie am Unvermögen, Souveränität in Teilbereichen aufzugeben und mit der Demokratie umzugehen. In dieser Arbeit wird unter erstmaliger Berücksichtigung des Moskauer Archivbestandes (Beuteakten aus dem Zweiten Weltkrieg) eine gesamtheitliche Darstellung der Paneuropa-Bewegung in der Zwischenkriegszeit geboten. Zunächst wird der Gründer der Paneuropa-Bewegung biografisch dargestellt; unmittelbar vor dem chronologischen Abriss der Paneuropa-Bewegung erfolgt die Analyse des Paneuropa-Programms und dessen Anpassung an die damaligen politischen Verhältnisse; die Erörterung organisatorischer Fragen wie bspw. die Finanzierung und propagandistischer Themen ergänzen diesen Schwerpunkt. Im Anschluss wird Paneuropa, in die europäische aber auch österreichische Politik der damaligen Zeit eingebunden, dargestellt; Schließlich erfolgt die Darstellung des Versuches ab 1933, Paneuropa wirtschaftlich bzw. gegen Ende der Bewegung kulturell zu vereinigen (Rettung des Abendlandes). Der Längsschnittdarstellung folgt die Querschnittdarstellung, nämlich über den Umgang Paneuropas bzw. Coudenhoves mit den Ideologien und geistigen Strömungen der damaligen Zeit. Im Vergleich zwischen Paneuropa und Europäischer Union findet man einige Parallelen, sodass man - - mit Einschränkungen - durchaus Paneuropa als Avantgarde für die Europäische Union bezeichnen kann.

    Description: The intention of this paper is to give a correct inside in the review of the discussed periods. It tries to achieve this by using the means of Art History and Political History to get an exact inside. The allegorical representation of the Austria in this case is the means to get it. It stands for the specific aspects of the time, so for instance the dynastic Austria with the crown of Emperor Rudolph II. meaning the predominance of the ruling Habsburgs, the civic Austria with the mural crown showing the ideas of the middle class, especially in the German speaking parts of the country, with the acceptance of the predominance of the state over the ruler, according to Hegel, or also the victorious Austria with the laurel wreath as a symbol of the conquest of the revolution of 1848. The Habsburg monarchy including many different nations was the proper breeding ground of dissatisfaction and diversified nationalistic ideas. So the representation of the Austria is an important means of showing these ideas. The periods the paper is working on are roughly speaking starting with the time of the beginning of the position of the monarchy as one of the ruling powers of Europe until her dissolution and the end of World War I. Different aspects of art history are also dealt with. So for example the 13 portraits of Habsburg rulers in the Museum Nordico at Linz, which are positioned in the time of Rudolph II. and mark the beginning of the representation of the allegory of the Austria, or the designs for monuments by Otto Wagner which are dealt with in the many books on this architect only as a side issue, whereas they are a very important part of wagners work and show his national feelings, towards his fatherland. It is furthermore interesting to look at the nationalistic problems shown in this paper and compare them with contemporary Europe and the overcoming of them. These ideas are not new, the date back to the 19th and especially the beginning of the 20th century when the Monarchy tried to overcome the problems with the slogan of Großösterreich (Greater Austria). During World War one followed the idea of Mitteleuropa (Central Europe) including Turkey and the institution of a Polish State to hold off revolutionary Russia
    Description: Diese Arbeit ist der Versuch, durch die Verbindung von kunsthistorischen und politikgeschichtlichen Erkenntnissen ein genaueres korrekteres Bild der behandelten Epochen zu erhalten. Die Allegorie der Austria ist dabei das Instrument zur genauen Evaluierung der jeweiligen nationalen und staatspolitischen Vorstellungen. Die Allegorie der Austria verkörpert dabei sehr genau die jeweiligen politischen Konstellationen. Die dynamische Austria mit der rudolphinischen Hauskrone bedeutet die Prädominanz des Herrscherhauses, die bürgerliche Austria mit der Mauerkrone die Vorstellungen dieser Bevölkerungsschicht, vor allem im deutschsprachigen Teil von Österreich, die Stellung des Staates über dem Herrscher der Sinne Hegels, sowie auch die siegreiche Austria mit dem Lorbeerkranz als Zeichen der Überwindung der Revolution von 1848. Gerade im Vielvölkerstaat der Habsburger, wo die divergierenden gesamtstaatlichen und nationalen Sichtweisen zu Konflikten führen mußten, ist so die Allegorie der Austria ein wichtiger Hinweis auf die jeweilige Stellung der Öffentlichkeit zu der angedeuteten Problematik. Der in der Arbeit vorgegebene Zeitraum umfaßt die Periode vom Beginn des Aufstiegs Österreichs zur Großmacht bis zum Ende der Monarchie nach dem ersten Weltkrieg. Dabei werden verschiedene künstlerische Aspekte in einer neueren und genaueren Betrachtungsweise angesprochen, wie zum Beispiel der Zyklus von 13 Porträts aus dem Umfeld von Rudolph II. im Linzer Museum Nordico, die in der großen Ausstellung über diesen Herrscher "Prag um 1600" nicht repräsentiert waren und die am Beginn der Austria-Allegorie in der bildenden Kunst stehen, oder die Denkmalsentwürfe Otto Wagners, die im Großteil der Literatur über diesen Architekten nur als Gelegenheitsentwürfe bezeichnet werden, aber in Wahrheit ernstzunehmende Auseinandersetzungen Wagners mit der nationalen Kunst sind. Ein weiterer gedanklicher Ansatzpunkt ist der Vergleich des Ringens um einen modernen Gesamtstaat vor allem seit dem Anfang des 20. Jahrhunderts im Verhältnis zum heutigen Europa mit seinen überstaatlichen Strukturen. Dazu gehört die im Weltkrieg aufgekommene Idee von Mitteleuropa unter Einschluß der Türkei und der Wiedererrichtung des Königreiches Polen als Pufferstaat gegenüber dem revolutionären Russland. Hier ist schon lange vor der Gründung der europäischen Union der Versuch gemacht, den Kontinent friedlich zu einen.

    Description: To keep up with the ever-increasing data transmission speed needs, data center interconnects are scaling up to provide multi-Tbit/s connectivity. These links require a high number of WDM channels, while the associated transceivers should be compact and energy efficient. Scaling the number of channels, however, is still limited by the lack of adequate optical sources. In this book, we investigate novel chip-scale frequency comb generators as multi-wavelength light sources for Tbit/s WDM links.

Thermal storage is required for a flexible operation of CHPs. This work proposes three novel methods to use a heating grid as thermal storage by exploiting its thermal dynamics. These include the first approach proving global optimality, a novel linear formulation of grid dynamics and an easily real world applicable approach.

    Description: During the evolvement of autonomous driving technology, obtaining reliable 3-D environmental information is an indispensable task in approaching safe driving. The operational behavior of automotive radars can be precisely evaluated in a virtual test environment by modeling its surrounding, specifically vulnerable road users (VRUs). Such a realistic model can be generated based on the radar cross section (RCS) and Doppler signatures of a VRU. Therefore, this work proposes a high-resolution RCS measurement technique to determine the relevant scattering points of different VRUs.

    Description: In recent years, OFDM has become more and more important for radar applications. A disadvantage, however, is the need for high sampling rates, which is exactly the starting point of the frequency comb OFDM radar scheme. With its help, the bandwidth in the radar channel can be enhanced without increasing the sampling rates at the same time. In this way, a high range resolution can be achieved without using fast converters with high sampling rates.

    Description: In this work, the first simulation model of oxygen depolarized cathodes (ODC), which are silver catalyst-based gas diffusion electrodes, is presented that considers the phase equilibrium of the gas-liquid interface and structure-related inhomogeneities in electrolyte distribution. By means of the model it has been identified that mass transport of water and ions in the liquid phase is a crucial factor for electrode performance and how it is influenced by the electrode structure.

    Description: In this work describes the development of a light-based driver assistance system through projections on the road. Under realistic conditions it is shown that information can be transmitted to the driver at night by using projections in front of the vehicle: test persons drive more safely through narrow spaces and react earlier to obstacles. A prototype suitable for road use demonstrates the possibility of a near-series implementation of such a headlamp projection system.

    Description: In this work, two methods are developed and evaluated to integrate and test functional chains of automotive lighting functions on simulation-based test systems. The focus is initially on an approach for the efficient use of light for the display of high contrasts in virtual night driving with a real driver assistance camera. Furthermore, a test method is developed to evaluate pixel-based lighting functions on a hardware-in-the-loop test system based on metrics. In this work, two methods to stimulate and test automotive front lighting functions on simulation-based test benches are developed and evaluated. The first approach deepens the idea to reach necessary high contrasts for virtual night driving with a real driver assistance camera by an efficient use of reflecting light. Furthermore, a test method is shown to test pixel-based lighting functions based on metrics on a hardware-in-the-loop test bench.

    Description: This work presents the development of a new sub-THz source for the generation of trains of coherent high-power ultra-short pulses at 263 GHz via passive mode-locking of two coupled helical gyro-TWTs. For the first time, it is shown that the operation of such passive mode-locked helical gyro-TWTs in the hard excitation regime is of particular importance to reach the optimal coherency of the generated pulses. This could be of particular interest for some new time-domain DNP-NMR methods.

    Description: The years 1989/1990 saw the fall of the Iron Curtain. Following forty years of significant restrictions, legal and non-bureaucratic travel from East-Central and Eastern European countries was once again possible and travelling and returning to those countries became just as easy. Immediately following the end of the East-West conflict, people from East-Central and Eastern European countries took advantage of their new freedom of travel. Many sought to emigrate to Western countries. However, when faced with such immigration, the euphoria which met the end of the political divisions in the West evaporated quickly. Several polls and surveys, projections and prognoses served to unsettle people more than the reality of immigration. This gave rise to a sometimes blind and specious – yet nevertheless politically effective – fear of a new mass migration of peoples. Now, more than ten years after the fall of the Iron Curtain, the actual scale and development of the East-West migration in Europe be clearly evaluated. This book attempts to do just that, including a comprehensive overview and eleven country-specific chapters. Each chapter includes a historical review, an account of the most important changes since 1989/1990 and a forecast of future migration developments.
    Description: 1989/90 fiel der Eiserne Vorhang. Nach mehr als 40 Jahren erheblicher Einschränkungen wurde die legale und unbürokratische Anreise aus den Staaten Ostmittel- und Osteuropas wieder möglich. Genauso leicht wurde die Ein- und Rückreise dorthin. Unmittelbar nach Ende des Ost-West-Konflikts begannen die Bürger Ostmittel- und Osteuropas, von dieser neuen Reisefreiheit Gebrauch zu machen. Etliche versuchten, in ein westliches Land auszuwandern. Angesichts solcher Zuwanderung verflog die Euphorie über das Ende der politischen Spaltung Europas im Westen relativ rasch. Mehr noch als die tatsächliche Migration beunruhigten aber diverse Umfragen, Hochrechnungen und Prognosen die öffentliche Meinung. Es entstand eine teilweise unreflektierte und vordergründige, aber politisch höchst wirksame Angst vor einer neuen Völkerwanderung in Europa. Mehr als zehn Jahre nach dem Fall des Eisernen Vorhangs können nun tatsächliche Größe und Entwicklung der Ost-West-Wanderung in Europa klar abgeschätzt werden. Damit befasst sich dieses Buch. Es enthält eine Übersichtsdarstellung und elf Länderkapitel. Diese beinhalten jeweils einen historischen Rückblick, eine Darstellung der wichtigsten Veränderungen seit 1989/90 und eine Einschätzung der zukünftigen Migrationsentwicklung.

    Description: Radar target simulators (RTSs) deceive a radar under test (RuT) by creating an artificial environment consisting of virtual radar targets. In this work, new techniques are presented that overcome the rasterization deficiency of current RTS systems and enable the generation of virtual targets at arbitrary high-precision positions. This allows for continuous movement of the targets and thus a more credible simulation environment.

    Description: The electrification and automation of passenger vehicles promote innovations of the entire vehicle architecture. If wheel-selective steered and driven vehicles are considered, challenges of urban regions can be met. In order to combine these development priorities with the alternative vehicle concept, an optimal suspension is designed for the vehicle concept. The topology optimization of a virtual wheel suspension takes place in interaction with a continuous, optimal dynamics vehicle control.

    Description: This work presents model-based algorithmic approaches for interference-invariant time delay estimation, which are specifically suited for the estimation of small time delay differences with a necessary resolution well below the sampling time. Therefore, the methods can be applied particularly well for transit-time ultrasonic flow measurements, since the problem of interfering signals is especially prominent in this application.

    Description: Die Arbeit beschäftigt sich mit den soziologischen Herausforderungen der Globalisierung und ihrem Einfluss auf die Sozialwissenschaften. Dabei wird vor allem nach den Parametern des Raums und der Identität im Prozess der Globalisierung gefragt. Innerhalb eines deutschen Kontextes wird untersucht, wodurch Migrationsprozesse konstituiert sind, welche Probleme und Orientierungsunsicherheiten sie nach sich ziehen können und wie mit kultureller Differenz umgegangen wird. Es werden zudem Vorschläge zu möglichen Veränderungsprozessen in der Kulturpolitik und Kulturarbeit gemacht.
