  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  = {Brazilian battlers' housing discusses the self-production of dwellings in the circumstances of the socioeconomic rise of the so-called Brazilian new middle class, occurred on the first decade of the years 2000. Battlers are a precarious working class of about 100 million people, who have used their recently increased purchase power to informally solve their private housing demands, planning, building and renovating their homes themselves, with limited technical knowledge and almost no access to formal technicians as for example architects. The result is a mode of housing production, which spreads over the territory in micro-local self-initiatives and informal social practices of construction and management. With the support of a controversial manpower, this practice presents all sorts of technical complications, but at the same time expedient ways of affordability and creative spatial solutions for ordinary constructive problems. Such initiatives have consolidated Brazilian informal settlements and peripheral subdivisions, attending a demand poorly responded by the government. This research recognises the benefits of the self-production, but questions the conditions under which it happens and asks if it really collaborates for a true social rise of those who are engaged in it. With an empirical and qualitative approach and taking dwelling construction processes leaded by battlers as main information sources, the academic work responds if and how the socioeconomic rise of the Brazilian battlers has exactly affected the self-production of dwellings. For that, battlers' self-production of dwellings is analysed and discussed in five main aspects: 1) acquisition of land and real state, 2) building overtime, 3) space and creative power, 4) technical complications and building materials and 5) manpower and know-how.},

  abstract  = {Turbomachinery plays an important role in many cases of energy generation or conversion. Therefore, turbomachinery is a promising approaching point for optimization in order to increase the efficiency of energy use. In recent years, the use of automated optimization strategies in combination with numerical simulation has become increasingly popular in many fields of engineering. The complex interactions between fluid and solid mechanics encountered in turbomachines on the one hand and the high computational expense needed to calculate the performance on the other hand, have, however, prevented a widespread use of these techniques in this field of engineering. The objective of this work was the development of a strategy for efficient metamodel based optimization of centrifugal compressor impellers. In this context, the main focus is the reduction of the required numerical expense. The central idea followed in this research was the incorporation of preliminary information acquired from low-fidelity computation methods and empirical correlations into the sampling process to identify promising regions of the parameter space. This information was then used to concentrate the numerically expensive high-fidelity computations of the fluid dynamic and structure mechanic performance of the impeller in these regions while still maintaining a good coverage of the whole parameter space. The development of the optimization strategy can be divided into three main tasks. Firstly, the available preliminary information had to be researched and rated. This research identified loss models based on one dimensional flow physics and empirical correlations as the best suited method to predict the aerodynamic performance. The loss models were calibrated using available performance data to obtain a high prediction quality. As no sufficiently exact models for the prediction of the mechanical loading of the impellercould be identified, a metamodel based on finite element computations was chosen for this estimation. The second task was the development of a sampling method which concentrates samples in regions of the parameter space where high quality designs are predicted by the preliminary information while maintaining a good overall coverage. As available methods like rejection sampling or Markov-chain Monte-Carlo methods did not meet the requirements in terms of sample distribution and input correlation, a new multi-fidelity sampling method called "Filtered Sampling"has been developed. The last task was the development of an automated computational workflow. This workflow encompasses geometry parametrization, geometry generation, grid generation and computation of the aerodynamic performance and the structure mechanic loading. Special emphasis was put into the development of a geometry parametrization strategy based on fluid mechanic considerations to prevent the generation of physically inexpedient designs. Finally, the optimization strategy, which utilizes the previously developed tools, was successfully employed to carry out three optimization tasks. The efficiency of the method was proven by the first and second testcase where an existing compressor design was optimized by the presented method. The results were comparable to optimizations which did not take preliminary information into account, while the required computational expense cloud be halved. In the third testcase, the method was applied to generate a new impeller design. In contrast to the previous examples, this optimization featuredlargervariationsoftheimpellerdesigns. Therefore, theapplicability of the method to parameter spaces with significantly varying designs could be proven, too.},

  abstract  = {Due to an increased need for hydro-electricity, water storage, and flood protection, it is assumed that a series of new dams will be built throughout the world. Comparing existing design methodologies for arch-type dams, model-based shape optimization can effectively reduce construction costs and leverage the properties of construction materials. To apply the means of shape optimization, suitable variables need to be chosen to formulate the objective function, which is the volume of the arch dam here. In order to increase the consistency with practical conditions, a great number of geometrical and behavioral constraints are included in the mathematical model. An optimization method, namely Genetic Algorithm is adopted which allows a global search. Traditional optimization techniques are realized based on a deterministic approach, which means that the material properties and loading conditions are assumed to be fixed values. As a result, the real-world structures that are optimized by these approaches suffer from uncertainties that one needs to be aware of. Hence, in any optimization process for arch dams, it is nec- essary to find a methodology that is capable of considering the influences of uncertainties and generating a solution which is robust enough against the uncertainties. The focus of this thesis is the formulation and the numerical method for the optimization of the arch dam under the uncertainties. The two main models, the probabilistic model, and non-probabilistic models are intro- duced and discussed. Classic procedures of probabilistic approaches un- der uncertainties, such as RDO (robust design optimization) and RBDO (reliability-based design optimization), are in general computationally ex- pensive and rely on estimates of the system's response variance and fail- ure probabilities. Instead, the robust optimization (RO) method which is based on the non-probabilistic model, will not follow a full probabilistic approach but works with pre-defined confidence levels. This leads to a bi-level optimization program where the volume of the dam is optimized under the worst combination of the uncertain parameters. By this, robust and reliable designs are obtained and the result is independent of any as- sumptions on stochastic properties of the random variables in the model. The optimization of an arch-type dam is realized here by a robust optimiza- tion method under load uncertainty, where hydraulic and thermal loads are considered. The load uncertainty is modeled as an ellipsoidal expression. Comparing with any traditional deterministic optimization (DO) method, which only concerns the minimum objective value and offers a solution candidate close to limit-states, the RO method provides a robust solution against uncertainties. All the above mentioned methods are applied to the optimization of the arch dam to compare with the optimal design with DO methods. The re- sults are compared and analyzed to discuss the advantages and drawbacks of each method. In order to reduce the computational cost, a ranking strategy and an ap- proximation model are further involved to do a preliminary screening. By means of these, the robust design can generate an improved arch dam structure which ensures both safety and serviceability during its lifetime.},

Deshalb widmet sich die Dissertation zuerst der Literaturrecherche, sowohl was den Begriff der kinder- und jugendfreundlichen Stadtentwicklung angeht als auch der Literatur bez{\"u}glich des Beitrags der Schulen zur Realisierung der kinder- und jugendfreundlichen Stadtentwicklung. Danach wird untersucht, ob das deutsche Instrument ‚Spielleitplanung' sich als Leitfaden f{\"u}r die gesamte Konzeption der koreanischen kinder- und jugendfreundlichen Stadtentwicklung eignet.

Zuletzt werden anhand der Untersuchungsergebnisse Handlungs-empfehlungen f{\"u}r die Durchf{\"u}hrung der koreanischen kinder- und jugend-freundlichen Stadtentwicklung formuliert. Anhand dieser Forschung kann konstatiert werden, dass die kinder- und jugendfreundliche Stadtentwicklung eine wichtige Planungsidee ist, weil dadurch Stadtplanerinnen und Stadtplaner sowohl zum k{\"o}rperlichen und geistigen gesunden Aufwachsen von Kindern und Jugendlichen als auch zur Entwicklung ihrer sozialen Kompetenzen erheblich beitragen k{\"o}nnen. Vor allem soll man die koreanische kinder- und jugendfreundliche Stadtentwicklung zun{\"a}chst auf den Schulen und den schulischen Umgebungen umsetzen. Denn dadurch lassen sich vielseitige eventuelle Hindernisse bei der Durchf{\"u}hrung der kinder- und jugendfreundlichen Stadtentwicklung vermeiden. Ein weiterer Grund ist, dass die Schulen in Korea nicht nur in der Gesellschaft eine zentrale Rolle spielen, sondern auch im Rahmen der Stadtplanung. Auff{\"a}llig ist, dass die kinder- und jugendfreundliche Stadtentwicklung sowohl auf die r{\"a}umlichen Gestaltungen als auch auf die Beteiligung von Kindern und Jugendlichen in der st{\"a}dtischen Planung fokussiert ist. Allerdings werden bei der Stadtentwicklung die Kinder und Jugendliche in Korea noch nicht als wichtige Akteure angesehen. Darum soll man die Spielleitplanung in Korea einbeziehen, weil sie als Leitbild bei einer Konzeption der koreanischen kinder- und jugendlichen Stadtentwicklung fungieren kann. Jedoch m{\"u}ssen dabei die kulturellen Unterschiede zwischen Deutschland und Korea ber{\"u}cksichtigt werden. Weiterhin wurde durch die Interviews festgestellt, dass das Interesse und der Wille von Experten aus der Stadtplanung an Kinder- und Jugendfreundlichkeit die wichtigsten Voraussetzungen sind, um die kinder- und jugendfreundliche Stadtentwicklung in Korea zu verankern und zu verbreiten.},

  abstract  = {The underlying goal of this work is to reduce the uncertainty related to thermally induced stress prediction. This is accomplished by considering use of non-linear material behavior, notably path dependent thermal hysteresis behavior in the elastic properties. Primary novel factors of this work center on two aspects. 1. Broad material characterization and mechanistic material understanding, giving insight into why this class of material behaves in characteristic manners. 2. Development and implementation of a thermal hysteresis material model and its use to determine impact on overall macroscopic stress predictions. Results highlight microcracking evolution and behavior as the dominant mechanism for material property complexity in this class of materials. Additionally, it was found that for the cases studied, thermal hysteresis behavior impacts relevant peak stress predictions of a heavy-duty diesel particulate filter undergoing a drop-to-idle regeneration by less than ~15\% for all conditions tested. It is also found that path independent heating curves may be utilized for a linear solution assumption to simplify analysis. This work brings forth a newly conceived concept of a 3 state, 4 path, thermally induced microcrack evolution process; demonstrates experimental behavior that is consistent with the proposed mechanisms, develops a mathematical framework that describes the process and quantifies the impact in a real world application space.},

  abstract  = {Railway systems are highly competitive compared with other means of transportation because of their distinct advantages in speed, convenience and safety. Therefore, the demand for railway transportation is increasing around the world. Constructing railway tracks and related engineering structures in areas with loose or soft cohesive subgrade usually leads to problems, such as excessive settlement, deformation and instability. Several remedies have been proposed to avoid or reduce such problems, including the replacement of soft soil and the construction of piles or stone columns. This thesis aims to expand the geotechnical knowledge of how to improve subgrade ballasted railway tracks, using stone columns and numerical modeling for the railway infrastructure. Three aspects are considered: i) railway track dynamics modeling and validation by field measurements, ii) modeling and parametric studies on stone columns, and iii) studies on the linear and non-linear behavior of stone columns under the dynamic load of trains. The first step of this research was to develop a reliable numerical model of a railway track. The finite element method in a time domain was used for either a 2D plane strain or 3D analysis. Individual methods for modeling a train load in 2D and 3D were implemented and are discussed in this thesis. The developed loading method was validated with three different railway tracks using obtained vibration measurements. Later, these numerical models were used to analyze the influence of stone column length and train speed in the stress field. The performance of the treated ground depends on various parameters, such as the strength of stone columns, spacing, length and diameter of the columns. Therefore, the second step was devoted to a parameter study of stone columns as a unit cell with an axisymmetric condition. The results showed that even short stone columns were effective for settlement reduction, and area of replacement was the main influential parameter in their performance. The third part of this thesis focuses on a hypothetical railway-track response to the passage of various train speeds and the influence of stone-column length. The stress-strain response of subgrade is analyzed under either an elastic-perfectly plastic or advanced constitutive model. The non-linear soil response in the finite element method and the impact of train speed and stone column length on railway tracks are also evaluated. Moreover, the reductions of induced vibration - in both a horizontal and a vertical direction - after improvement are investigated.},

  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.‎},

Dabei wirft die Typologie des Siedlungsbaus besondere Fragen auf, da sie neben architektonischen Aspekten auch st{\"a}dtebauliche, landschaftsplanerische und sozialwissenschaftliche Bedeutungsebenen umfasst. Nicht zuletzt sind Siedlungen der 1950er bis 1980er Jahre aus denkmalpflegerischer Sicht h{\"a}ufig stark gef{\"a}hrdet. Obwohl die meisten Siedlungen noch nicht ausreichend kunsthistorisch gew{\"u}rdigt und erfasst sind, unterliegen sie einem hohen Ver{\"a}nderungsdruck. Die teilweise enorme st{\"a}dtebauliche Dimension und Monofunktionalit{\"a}t der Anlagen, die h{\"a}ufig aufgrund von seriellen Bautypen und vorfabrizierten Elementen gleichf{\"o}rmige architektonische Gestaltung und eine Vernachl{\"a}ssigung im Bauunterhalt erschweren den Zugang zu dieser Baugattung. Gewandelte Wohnbed{\"u}rfnisse sowie bauphysikalische, energietechnische oder {\"a}sthetische Maßnahmen f{\"u}hren zur Ver{\"a}nderung der noch relativ jungen Bausubstanz. Zudem weisen Siedlungen der Nachkriegszeit aufgrund ihrer teilweise sehr großz{\"u}gigen Freiraumstruktur ein großes Potential zur Nachverdichtung auf. Die Auswahl der in dieser Arbeit untersuchten L{\"a}nder und Siedlungen ergab sich aus der Auswertung einer europaweiten Befragung von Denkmal{\"a}mtern sowie anschließend gef{\"u}hrten Gespr{\"a}chen mit Fachleuten. Die untersuchten 20 Siedlungen und Wohnanlagen repr{\"a}sentieren verschiedene L{\"a}nder (Deutschland, {\"O}sterreich, Schweiz, Frankreich, Niederlande, England) sowie Bauepochen und Siedlungstypologien, die von der Einfamilienhaussiedlung {\"u}ber Siedlungen mit gemischter Bautypologie hin zur Großsiedlung reichen. Anhand der unterschiedlichen Fallbeispiele wird aufgezeigt, inwiefern die jeweiligen L{\"a}nder, Bauepochen beziehungsweise Siedlungstypologien Einfluss auf die denkmalpflegerischen Erfassungsstrategien haben. Zusammenfassend l{\"a}sst sich res{\"u}mieren, dass die Gesetzesgrundlagen und Denkmalkriterien f{\"u}r eine denkmalpflegerische Erfassung von Bauten der 1950er bis 1980er Jahre in den meisten L{\"a}ndern konstant bleiben, w{\"a}hrend sich in den Bereichen Zeitpunkt, Auswahl und Einbindung der {\"O}ffentlichkeit eine Modifizierung oder zumindest eine Reflektion der bisherigen Strukturen abzeichnet. Sinnvoll und w{\"u}nschenswert erscheint dar{\"u}ber hinaus ein verst{\"a}rkter Austausch der Denkmalpflege {\"u}ber die nationalen Grenzen hinweg und ein gegenseitiges Lernen voneinander.},

  abstract  = {Modern image detection techniques such as micro computer tomography (μCT), magnetic resonance imaging (MRI) and scanning electron microscopy (SEM) provide us with high resolution images of the microstructure of materials in a non-invasive and convenient way. They form the basis for the geometrical models of high-resolution analysis, so called image-based analysis. However especially in 3D, discretizations of these models reach easily the size of 100 Mill. degrees of freedoms and require extensive hardware resources in terms of main memory and computing power to solve the numerical model. Consequently, the focus of this work is to combine and adapt numerical solution methods to reduce the memory demand first and then the computation time and therewith enable an execution of the image-based analysis on modern computer desktops. Hence, the numerical model is a straightforward grid discretization of the voxel-based (pixels with a third dimension) geometry which omits the boundary detection algorithms and allows reduced storage of the finite element data structure and a matrix-free solution algorithm. This in turn reduce the effort of almost all applied grid-based solution techniques and results in memory efficient and numerically stable algorithms for the microstructural models. Two variants of the matrix-free algorithm are presented. The efficient iterative solution method of conjugate gradients is used with matrix-free applicable preconditioners such as the Jacobi and the especially suited multigrid method. The jagged material boundaries of the voxel-based mesh are smoothed through embedded boundary elements which contain different material information at the integration point and are integrated sub-cell wise though without additional boundary detection. The efficiency of the matrix-free methods can be retained.},

  abstract  = {The capitalization of 'certified' sustainable building sector will be investigated over the power theory of value approach of Jonathan Nitzan and Shimshon Bichler. The study will be initiated by questioning why the environment problems are one of the first items on the agenda and by sharing the ideas of scholars who approaches the subject skeptically, because the predominant literature underlying the necessity and prominence of the topic is already well-known and adapted by the majority. Over the theory developed by Nitzan and Bichler, the concepts of capitalization, strategic sabotage, power, legitimacy, and obedience will be discussed. The hypothesis of "the absentee owners of the construction sector, holding the whip hand and capitalizing the ecology, control the growth and the creativity of green building production and make it carbon-dependent, in order to increase their profit margin" will be questioned. To strengthen the arguments in the hypothesis, the factors, the institutional arrangements, value measurement methods, which affect directly the net present value, will be investigated both in corporation and in building scale in detail, because net present value/ capitalization is asserted as the most important criteria by Nitzan and Bichler to make the investment decisions in the capitalist economic system. To trace the implications of power and the strategic sabotage that power caused, as the empirical dimension of this dissertation, an interface exploring the correlational ties between the climate responsive architecture and the ever changing political, economical, and social contexts and building economics praxis by decades will be developed and the expert interviews will be conducted with the design teams and the appraisers.},

  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.},

Die Kopplungselemente gestatten die einfache montagegerechte Verbindung von Holzbauteilen untereinander oder zu anderen Bauweisen.

Im Holz werden f{\"u}r die Verankerung der Kopplungselemente Bohrungen vorgesehen, die sich sowohl aus technologischen Gr{\"u}nden als auch f{\"u}r eine gleichm{\"a}ßige Spannungsverteilung vorteilhaft erweisen. Der Durchmesser der Bohrung ist gegen{\"u}ber dem Verbindungselement deutlich gr{\"o}ßer, wodurch die Verbindungsfl{\"a}che zum Holz bei konstanter L{\"a}nge ansteigt. Die Vergr{\"o}ßerung der Fugen zwischen dem Verbindungselement und der Holzwandung von 7 mm auf 17 mm f{\"u}hrt bei konstanter Einbindetiefe und gleichem Durchmesser des Verbin¬dungsmittels zu einer Laststeigerung von {\"u}ber 20 \%.

  abstract  = {This research seeks to make an exploratory study of the strategies used by the creators of monuments, memorials, and commemorative places located in the public spaces that use sound as one of the primary raw material in their design. The term acoustic monu-memorials was coined in this research to encircle these structures and places. In order to achieve the goal of this research, it was necessary to compile a number of samples, primarily after the digital recording era of captured sound around 1971 to the present. The compilation was relevant because such a compendium was not found in the literature, and to the author's knowledge, a comprehensive investigation of the strategies used in planning acoustic monu-memorials in the urban spaces does not exist. The method used to create such compendium was to send a question to people with different background identities, such as visual and sound artists, musicians, art curators, and heritage scholars among others. This question produced a selection of 51 examples of acoustic monu-memorials located in public spaces. Subsequently, the examples were classified into four major categories according to their form and nature. Additionally, two examples from the main categories were chosen as case studies: The Sinti and Roma Memorial in Berlin, Germany and the Niche monument in Cali, Colombia. These study cases were presented, described, and analysed in detail as they represent the type of what could be defined as an acoustic monu-memorial in general. Lynch's (1960) five elements that help individuals build the image of the city were transferred and used as a tool to help to build this image into acoustic terms. A thorough analysis of the acquired data yielded found the strategies used by the designers to shape, modify, transform, and structure public space. These strategies are entitled Sound Spaces. Moreover, a list entitled Urban Acoustic Commemoration Code was compiled. This list of suggestions addresses urban planners, architects, artists, designers, and general public interested in the aspects involved when creating acoustic commemoration phenomena in public spaces.},

Going beyond merely retrieving the most relevant result set for the current query, the retrieval system should aim to surface results that are actually useful to the task that motivated the query. This dissertation explores how retrieval systems can better understand and support their users' tasks from three main angles: First, we study and quantify search engine user behavior during complex writing tasks, and how task success and behavior are associated in such settings. Second, we investigate search engine queries formulated as questions, and explore patterns in a large query log that may help search engines to better support this increasingly prevalent interaction pattern. Third, we propose a novel approach to reranking the search result lists produced by web search engines, taking into account retrieval axioms that formally specify properties of a good ranking.},
