  abstract  = {The p-Laplace equation is a nonlinear generalization of the well-known Laplace equation. It is often used as a model problem for special types of nonlinearities, and therefore it can be seen as a bridge between very general nonlinear equations and the linear Laplace equation, too. It appears in many problems for instance in the theory of non-Newtonian fluids and fluid dynamics or in rockfill dam problems, as well as in special problems of image restoration and image processing. The aim of this thesis is to solve the p-Laplace equation for 1 < p < 2, as well as for 2 < p < 3 and to find strong solutions in the framework of Clifford analysis. The idea is to apply a hypercomplex integral operator and special function theoretic methods to transform the p-Laplace equation into a p-Dirac equation. We consider boundary value problems for the p-Laplace equation and transfer them to boundary value problems for a p-Dirac equation. These equations will be solved iteratively by applying Banach's fixed-point principle. Applying operator-theoretical methods for the p-Dirac equation, the existence and uniqueness of solutions in certain Sobolev spaces will be proved. In addition, using a finite difference approach on a uniform lattice in the plane, the fundamental solution of the Cauchy-Riemann operator and its adjoint based on the fundamental solution of the Laplacian will be calculated. Besides, we define gener- alized discrete Teodorescu transform operators, which are right-inverse to the discrete Cauchy-Riemann operator and its adjoint in the plane. Furthermore, a new formula for generalized discrete boundary operators (analogues of the Cauchy integral operator) will be considered. Based on these operators a new version of discrete Borel-Pompeiu formula is formulated and proved. This is the basis for an operator calculus that will be applied to the numerical solution of the p-Dirac equation. Finally, numerical results will be presented showing advantages and problems of this approach.},

  abstract  = {Since the Industrial Revolution in the 1700s, the high emission of gaseous wastes into the atmosphere from the usage of fossil fuels has caused a general increase in temperatures globally. To combat the environmental imbalance, there is an increase in the demand for renewable energy sources. Dams play a major role in the generation of "green" energy. However, these structures require frequent and strict monitoring to ensure safe and efficient operation. To tackle the challenges faced in the application of convention dam monitoring techniques, this work proposes the inverse analysis of numerical models to identify damaged regions in the dam. Using a dynamic coupled hydro-mechanical Extended Finite Element Method (XFEM) model and a global optimization strategy, damage (crack) in the dam is identified. By employing seismic waves to probe the dam structure, a more detailed information on the distribution of heterogeneous materials and damaged regions are obtained by the application of the Full Waveform Inversion (FWI) method. The FWI is based on a local optimization strategy and thus it is highly dependent on the starting model. A variety of data acquisition setups are investigated, and an optimal setup is proposed. The effect of different starting models and noise in the measured data on the damage identification is considered. Combining the non-dependence of a starting model of the global optimization strategy based dynamic coupled hydro-mechanical XFEM method and the detailed output of the local optimization strategy based FWI method, an enhanced Full Waveform Inversion is proposed for the structural analysis of dams.},

  abstract  = {Modern immersive telepresence systems enable people at different locations to meet in virtual environments using realistic three-dimensional representations of their bodies. For the realization of such a three-dimensional version of a video conferencing system, each user is continuously recorded in 3D. These 3D recordings are exchanged over the network between remote sites. At each site, the remote recordings of the users, referred to as 3D video avatars, are seamlessly integrated into a shared virtual scenery and displayed in stereoscopic 3D for each user from his or her perspective. This thesis reports on algorithmic and technical contributions to modern immersive telepresence systems and presents the design, implementation and evaluation of the first immersive group-to-group telepresence system in which each user is represented as realistic life-size 3D video avatar. The system enabled two remote user groups to meet and collaborate in a consistent shared virtual environment. The system relied on novel methods for the precise calibration and registration of color- and depth- sensors (RGBD) into the coordinate system of the application as well as an advanced distributed processing pipeline that reconstructs realistic 3D video avatars in real-time. During the course of this thesis, the calibration of 3D capturing systems was greatly improved. While the first development focused on precisely calibrating individual RGBD-sensors, the second stage presents a new method for calibrating and registering multiple color and depth sensors at a very high precision throughout a large 3D capturing volume. This method was further refined by a novel automatic optimization process that significantly speeds up the manual operation and yields similarly high accuracy. A core benefit of the new calibration method is its high runtime efficiency by directly mapping from raw depth sensor measurements into an application coordinate system and to the coordinates of its associated color sensor. As a result, the calibration method is an efficient solution in terms of precision and applicability in virtual reality and immersive telepresence applications. In addition to the core contributions, the results of two case studies which address 3D reconstruction and data streaming lead to the final conclusion of this thesis and to directions of future work in the rapidly advancing field of immersive telepresence research.},

  abstract  = {Recent years have seen a gradual shift in focus of international policies from a national and regional perspective to that of cities, a shift which is closely related to the rapid urbanization of developing countries. As revealed in the 2011 Revision of the World Urbanization Prospects published by the United Nations, 51\% of the global population (approximately 3.6 billion people) lives in cities. The report predicts that by 2050, the world's urban population will increase by 2.3 billion, making up 68\% of the population. The growth of urbanization in the next few decades is expected to primarily come from developing countries, one third of which will be in China and India. With rapid urbanization and the ongoing growth of mega cities, cities must become increasingly resilient and intelligent to cope with numerous challenges and crises like droughts and floods arising from extreme climate, destruction brought by severe natural disasters, and aggregated social contradictions resulting from economic crises. All cities face the urban development dynamics and uncertainties arising from these problems. Under such circumstances, cities are considered the critical path from crisis to prosperity, so scholars and organizations have proposed the construction of "resilient cities." On the one hand, this theory emphasizes cities' defenses and buffering capacity against disasters, crises and uncertainties, as well as recovery after destruction; on the other hand, it highlights the learning capacity of urban systems, identification of opportunities amid challenges, and maintenance of development vitality. Some scholars even believe that urban resilience is a powerful supplement to sustainable development. Hence, resilience assessment has become the latest and most important perspective for evaluating the development and crisis defense capacity of cities. Rather than a general abstract concept, urban resilience is a comprehensive measurement of a city's level of development. The dynamic development of problems is reflected through quantitative indicators and appraisal systems not only from the perspective of academic research, but also governmental policy, so as to scientifically guide development, and measure and compare cities' development levels. Although international scholars have proposed quantitative methods for urban resilience assessment, they are however insufficiently systematic and regionally adaptive for China's current urban development needs. On the basis of comparative study on European and North American resilient city theories, therefore, this paper puts forwards a theoretical framework for resilient city systems consistent with China's national conditions in light of economic development pressure, natural resource depletion, pollution, and other salient development crises in China. The key factors influencing urban resilience are taken into full consideration; expert appraisal is conducted based on the Delphi Method and the analytic hierarchy process (AHP) to design an extensible and updatable resilient city evaluation system which is sufficiently systematic, geographically adaptable, and sustainable for China's current urban development needs. Finally, Changsha is taken as the main case for empirical study on comprehensive evaluation of similar cities in Central China to improve the indicator system.},

  abstract  = {During the British occupation of Egypt in the beginning of the 20th century, several suburban developments were established on the periphery of the city of Cairo. These initially attracted the small British community and later foreigners and Egyptians, mainly from the elite community. These suburban developments, including Ma'ādī, Zamālik, Heliopolis, Qubbah-Gardens, and Garden City, became the fashionable residential quarters of Cairo. Until now, some of these areas still represent the distinguishable residential settlements of the city. Ma'ādī, Zamālik, and Heliopolis specifically are nostalgically appropriated in the design of recent suburban developments around Greater Cairo. Some of the 20th century suburban developments around Cairo are labeled or described as "garden cities." During the early 20th century, two thriving British town planning movements emerged, namely, the garden city movement and the garden suburb movement. This study investigates the hypothesis that these suburban developments, are indeed "garden suburbs" like the British movement, despite that few are labeled or described as "garden cities,". Although several studies have examined the historical development of such settlements, their relation, however, to the British planning movements and their transfer process received little attention from planning historians. Few studies also analyze the urban design aspects that made these suburban developments distinguishable since their foundation and until today. To guide the validity of this study's hypothesis, a set of research questions are formulated: (1) What is the difference between the garden city and the garden suburb movements? (2) How were the British planning movements transferred to Egypt? (3) What are the urban design aspects that makes these suburban developments distinguishable as garden suburbs? To answer these research questions, a historical morphological urban analysis is conducted through case studies. The study first studies the difference between the garden city and the garden suburb movements, mainly in Britain, through the analysis of publications on the promoter of both movements: for the garden city, E. Howards' book "The Garden City of Tomorrow," published in 1902, and for the garden suburb, R. Unwin's books "Town Planning in Practice," published in 1909, and "Nothing Gained from Overcrowding," published in 1912. Then a morphological urban analysis of Letchworth Garden City and Brentham Garden Suburb, considered the first examples of each movement, is conducted. In order to analyze the transfer process, the study adopts M. Volait and J. Nasr's theory on transporting planning, through investigating the authority in power responsible for the establishment of these suburban developments. This is followed by the morphological urban analysis of three suburban developments around Cairo, namely, Zamālik, Ma'ādī, and Heliopolis. The morphological analysis focuses on the background of their establishment, authority in power responsible for the development, design principles, urban context, street typology, residential block typology, social infrastructure, and social target group. Finally, the study compares between Brentham, Letchworth, Zamālik, Ma'ādī, and Heliopolis. The comparative analysis aims to highlight the differences between the studied cases of Cairo and how they are different from or alike the British movements. This study concludes that the suburban developments around Cairo during the British occupation, are in fact garden suburbs, despite that some are being described or labeled as garden city. This movement was exported via urban land development companies with foreign European capital, rather than via colonial dominance. It finally highlights a set of urban design aspects that distinguish them as garden suburbs of Cairo. This study hopes to support future conservation plan of these areas and the design of future suburban developments.},

  abstract  = {The study of memory, architecture, and urban space has been the interest ‎of ‎researchers ‎from the diverse fields around the world due to, the significance of dealing ‎with ‎memories ‎especially after the tragedy of the Second World War. Nations in Europe has chosen ‎not to ‎neglect ‎their past, moreover, overcoming it by strengthening the national identity. An ‎approach was clear in ‎the literature, art, further in the way of rebuilding their cities; that mainly ‎has reflected on the ‎value of urban spaces and their role in narrating the country's national ‎memory. Thanks to this ‎approach, which has supported the post-war European nations to invite ‎to an act of ‎ forgiveness rather than to forget. ‎ On the contrary, memory, in relation to architecture is a form of knowledge has been ‎neglected in Egypt, especially during the previous decades after the declaration of independence ‎from the colonial power, and since 1952 revolution. Recently, a rising debate about Egypt ‎national history and the need to renationalize the Egyptian historical consciousness has rapidly ‎grown up, due to the political transformation has occurred because of the 25th uprising, 2011, ‎which unveiled the power of public spaces in constituting the nation thoughts, especially Tahrir ‎square.‎ At the same time, this has unveiled the results of neglecting the past instead of overcoming it; unveiled a present carries the danger of conflict and repeating previous mistakes. Researchers, historians, politicians, governmental organization, have ‎worked in the purpose of revisiting the historical information, and have tried to document the ‎current transformation of the 25th uprising. There was a public demand for redesigning Tahrir square to reflect the ‎memory of the uprising as a symbol of the power of the public. However, after eight years, those ‎memories have faded as if the 25th uprising has never happened. ‎ Those circumstances are very relevant to the gap between urban design and the art of ‎memory-work, in the scientific field. Few studies in Egypt conducted the concept of memory in ‎relation to urban spaces, however, the matter requires more attention, to associate the need for renationalizing Egypt ‎memory, with viewing urban space as a mean of narrating the country's national memory and ‎reflecting the citizens' current thoughts, as a try of nearing the distances between ‎competing ‎narratives. Therefore, the research aims at developing a methodological framework that should ‎contribute to renationalizing memory through urban space. Further, benefiting from the German experience by investigating lessons to learn. That is based on the hypothesis that, although there is no fixed formula for all countries to renationalize the historical ‎consciousness of memory through urban spaces, lessons to be learned from Germany experience ‎could be a driving dimension when designing Egyptian urban spaces with a concept of memory ‎as an essential factor. To guide the validity of the study's hypothesis, a set of research questions are thus ‎formulated: Starting from why memory is an essential factor when designing urban spaces? ‎Regarding Egypt national memory, how it was constituted through history and how to read its ‎representation on urban spaces? Also, the study quests the means of nationalizing memory ‎through urban spaces? And What are the learned lessons from the German experience?‎ The study tries to answer those questions. Via an inductive ‎analytical ‎methodology ‎which ‎moves from the gap of knowledge and from a particular situation ‎in Egypt, to study the German ‎experience in renationalizing the concept of memory through urban spaces.‎ ‎ Within the scope of the study, exploring Egypt prevailing narratives and the inherited ‎concepts which influenced the national memory is essential. Moreover, the research develops ‎analytical political psychosocial model that could help reading memories in urban spaces, ‎memory's actors, and memory influences. To validate this model, case studies are analysed in ‎light of the concluded aspects. Consequently, the expected result is to infer broad general ‎learned ‎lessons for the Egyptian case. ‎ Research findings and conclusions answer the research questions, interpret literature ‎review, recommend some guide points to three target groups: first, practice field; to encourage ‎designers to value the national and collective memories when designing urban spaces. Second, to ‎ask policymakers to take the public participation into consideration, when taking decisions related to urban ‎development. Third, the thesis recommends future researches of urban memory that connect ‎theoretical information with the practice field. ‎ Finally, enhancing the memory-work in relation to the national narrative, conveying a meaningful message, when ‎designing urban spaces could encourage citizens to learn, to interact, and to dissolve boundaries ‎between the competing narratives in post-conflict societies.‎},

  abstract  = {Die Dissertation „Hey! I'm an Angel! Zum Verh{\"a}ltnis von Medium, Subjekt und Wirklichkeit in Eija-Liisa Ahtilas Videoinstallationen" untersucht in der Hauptsache vier zentrale Videoinstallationen Ahtilas aus den Jahren 1995 bis 2014. Grundlegend ist die These, dass Ahtilas Arbeiten nicht, wie bisher angenommen, in den Kontext einer medien-, erkenntnis- und subjektkritischen Videokunst einzuordnen sind. Stattdessen werden sie als mediale Vehikel intersubjektiv gepr{\"a}gter Wirklichkeitserfahrungen f{\"u}r das Subjekt bereitgestellt: Entgegen dem aktuellen Forschungsstand arbeitet sich Ahtila nicht an der Kritik des Mediums Film/Video ab, das einen wirklichkeitsverf{\"a}lschenden oder -ersetzenden Einfluss auf das manipulierte Subjekt nimmt. Vielmehr nutzt die K{\"u}nstlerin das Potenzial des Mediums Film/Video aus, um einem relativ stabilen Subjekt die Wirklichkeitserfahrungen Anderer zu {\"o}ffnen und auf diese Weise seinen Erfahrungshorizont zu erweitern. Der systematische Schwerpunkt der Arbeit liegt erstens darauf, ein sich durch Ahtilas bisheriges Schaffen ziehendes ‚Ziel' der Integration der Betrachterin in eine intersubjektive Erfahrungssph{\"a}re nachvollziehbar zu machen. Hierf{\"u}r wird insbesondere eine Perspektive auf die fr{\"u}hen Arbeiten entwickelt, in der die Br{\"u}che in Ahtila Arbeiten integrative statt distanzierende Wirkung haben. Zweitens wird in eingehenden Analysen der Wandel verst{\"a}ndlich, der sich zwischen Ahtilas fr{\"u}her Schaffensphase (1995 - 2002) und der aktuellen Schaffensphase (seit 2010) hinsichtlich der Art und Weise vollzieht, wie diese Integration gelingt. Es zeigt sich, dass der Einstieg in die intersubjektiv gepr{\"a}gten Erfahrungssph{\"a}ren in der fr{\"u}hen Phase {\"a}sthetisch konstituiert ist. Mit der aktuellen Schaffensphase werden hingegen allt{\"a}gliche Formen der Empathie und Mimesis zentral, sowie deren leibliche Konsequenzen f{\"u}r die Betrachterin. Drittens wird eine zunehmende pragmatische Tendenz darin deutlich, die Integration der Betrachterin in die Erfahrungen Anderer zu erm{\"o}glichen. Dies wird vor dem Hintergrund eines allgemeinen pragmatischen Zuges aktueller zeitgeistiger Bewegungen erl{\"a}utert. Viertens wird gezeigt, dass Ahtilas Arbeiten auf der Annahme einer Kontinuit{\"a}t in gewisser Hinsicht von der außerfilmischen Wirklichkeit in die filmische Fiktion hinein basieren, sowie auf dem Verst{\"a}ndnis filmischer Fiktionen als virtuelle Weltfassungen. Ahtila fragt auf der Grundlage dieses Verst{\"a}ndnisses filmischer Fiktion nicht nach der Wahrheit dieser Fiktion als These {\"u}ber die Wirklichkeit, wie es dem Forschungskanon {\"u}ber die K{\"u}nstlerin zu entnehmen ist. Sondern nach der Wirksamkeit der filmischen Fiktion f{\"u}r die Wirklichkeit.},
