  abstract  = {Es ist ein Bild aus alten Tagen: ein wissbegieriger Student, auf der Suche nach fundierter wissenschaftlicher Information, begibt sich an den heiligsten Ort aller B{\"u}cher - die Universit{\"a}tsbibliothek. Doch seit einiger Zeit tummeln sich Studierende nicht mehr nur in Bibliotheken, sondern auch immer h{\"a}ufiger im Internet. Sie suchen und finden dort digitale B{\"u}cher, sogenannte E-Books. Wie l{\"a}sst sich der Wandel durch den Einzug des E-Books in das etablierte Forschungssystem beschreiben, welche Konsequenzen lassen sich daraus ablesen und wird schließlich alles digital, sogar die Bibliothek? Diesen Fragen geht ein elfk{\"o}pfiges Expertenteam aus Deutschland und der Schweiz w{\"a}hrend der zweit{\"a}gigen Konferenz auf den Grund. Bei den Weimarer E-DOC-Tagen geht es nun um die Ver{\"a}nderung des institutionellen Gef{\"u}ges rund um das digitale Buch. Denn traditionell sind Verlage und Bibliotheken wichtige Bestandteile der Wissensversorgung in Studium und Lehre. Doch mit dem Aufkommen des E-Books verlagert sich die Recherche mehr und mehr ins Internet. Die Suchmaschine Google tritt als neuer Konkurrent der klassischen Bibliotheksrecherche auf. Aber auch Verlage m{\"u}ssen verst{\"a}rkt auf die neuen Herausforderungen eines digitalen Buchmarktes reagieren. In Kooperation mit der Universit{\"a}tsbibliothek und dem Master-Studiengang Medienmanagement diskutieren Studierende, Wissenschaftler, Bibliothekare und Verleger, wie das E-Book unseren Umgang mit Literatur ver{\"a}ndert. Der Tagungsband stellt alle Perspektiven und Ergebnisse zum Nachlesen zusammen.},

  abstract  = {Die neuere und h{\"o}chst produktive Konjunktur des »Kollektiv«-Begriffs in Soziologie und Kulturtheorie, wie sie sich insbesondere durch die Ent-faltung der Akteur-Netzwerk-Theorie herausgebildet hat, ist zun{\"a}chst durch vier miteinander zusammenh{\"a}ngende Eigent{\"u}mlichkeiten gekennzeichnet. Erstens bezeichnet das »Kollektiv« in diesem Sinne vor allem anderen eine Ansammlung von Entit{\"a}ten zu einem als Ganzem operativen, m{\"o}glicherweise sogar handlungs- und reflexionsf{\"a}higen Komplex. Die Operationen werden dabei erstens im »Kollektiv« und durch das »Kollektiv« ausgef{\"u}hrt, gleichzeitig jedoch sind sie es, die das »Kollektiv« {\"u}berhaupt erst aufspannen und relationieren und so zusammenhalten und reproduzieren bzw. variieren. Das Besondere daran ist zweitens - und das unterscheidet den »Kollektiv«-Begriff etwa von demjenigen des Systems -, dass es keine Subsumption der beteiligten Entit{\"a}ten unter das kollektive Gebilde gibt. Die Operationsf{\"a}higkeit und der Zusammenschluss f{\"u}hren weder zu einem Aufgehen des Einzelnen im Ganzen, noch zerf{\"a}llt im R{\"u}ckfall das Ganze in eine bloße Gesamtheit aufsummierbarer Teile und Effekte. Kurz: Das »Kollektiv« kann nicht {\"u}ber die Beziehung von Ganzem und Teil definiert und schon gar nicht nach einer dieser beiden Seiten hin aufgel{\"o}st werden. Drittens, und das ist der vermutlich plakativste Zug des neuen »Kollektiv«-Begriffs, umfasst das »Kollektiv« Entit{\"a}ten v{\"o}llig heterogener Art, genauer: Es bringt solche Gegebenheiten zusammen, die nach klassischer ontologischer Tradition verschiedenen Seinsbezirken zugerechnet worden w{\"a}ren. Das sind vor allem die ber{\"u}hmten menschlichen und nichtmenschlichen Akteure Bruno Latours, das sind also Personen und Artefakte, Kultur- und Naturdinge, Intelligibles und Sensibles, Reflexives und Irreflexives, Technisches und {\"A}sthetisches, Bilder und Objekte oder sogar Materielles und Immaterielles wie Geister, G{\"o}tter und Ahnen, so bei Descola oder Gell. Und viertens schließlich ist der »Kollektiv«-Begriff speziell ein Kontrastbegriff , der innerhalb der »neuen Soziologie« der Akteur-Netzwerk-Theorie an die Stelle des Gesellschaftsbegriff s treten soll, eben um dessen humanozentrische Pr{\"a}gung einerseits und seine subsumptive, generalisierende und anti-partikulare Tradition andererseits abzustreifen.},

Mit ihm kann je nach Kontext ebenso Zeichnen, Planen, Modellieren, Projektieren oder Darstellen gemeint sein wie Erfi nden, Entwickeln, Konzipieren, Komponieren und {\"a}hnliches. Wenn Architekten vom Entwurf reden, verwenden sie das Wort meist in einer Bedeutung, die auf den kunsttheoretischen Diskurs zur{\"u}ckgeht, der im Florenz des 16. Jahrhunderts entstanden ist: Entwurf als disegno. Dementsprechend konnte Entwerfen in der kunsthermeneutischen Rezeption schließlich mit dem ›k{\"u}nstlerischen Schaff ensprozess‹ selbst synonym werden. Im Entwerfen meint man der geistigen Verm{\"o}gen und Prozesse im k{\"u}nstlerischen Subjekt habhaft zu werden. An diese Tradition soll hier bewusst nicht angekn{\"u}pft werden. Um das Entwerfen als Kulturtechnik in seiner historischen Bedingtheit zu beschreiben, muss es aus dem anthropozentrischen Ursprung herausger{\"u}ckt werden, an den es der florentinische kunsttheoretische Diskurs versetzt hat. Statt das Entwerfen als fundamentalen Akt k{\"u}nstlerischen Schaff ens zu begreifen und als anthropologische Konstante der Geschichte zu entziehen, w{\"a}re eben diese Konzeption als historisches Resultat von diskursiven, technischen und institutionellen Praktiken zu befragen.},

  abstract  = {Long-span cable supported bridges are prone to aerodynamic instabilities caused by wind and this phenomenon is usually a major design criterion. If the wind speed exceeds the critical flutter speed of the bridge, this constitutes an Ultimate Limit State. The prediction of the flutter boundary therefore requires accurate and robust models. This paper aims at studying various combinations of models to predict the flutter phenomenon. Since flutter is a coupling of aerodynamic forcing with a structural dynamics problem, different types and classes of models can be combined to study the interaction. Here, both numerical approaches and analytical models are utilised and coupled in different ways to assess the prediction quality of the hybrid model. Models for aerodynamic forces employed are the analytical Theodorsen expressions for the motion-enduced aerodynamic forces of a flat plate and Scanlan derivatives as a Meta model. Further, Computational Fluid Dynamics (CFD) simulations using the Vortex Particle Method (VPM) were used to cover numerical models. The structural representations were dimensionally reduced to two degree of freedom section models calibrated from global models as well as a fully three-dimensional Finite Element (FE) model. A two degree of freedom system was analysed analytically as well as numerically. Generally, all models were able to predict the flutter phenomenon and relatively close agreement was found for the particular bridge. In conclusion, the model choice for a given practical analysis scenario will be discussed in the context of the analysis findings.},

  abstract  = {Different types of data provide different type of information. The present research analyzes the error on prediction obtained under different data type availability for calibration. The contribution of different measurement types to model calibration and prognosis are evaluated. A coupled 2D hydro-mechanical model of a water retaining dam is taken as an example. Here, the mean effective stress in the porous skeleton is reduced due to an increase in pore water pressure under drawdown conditions. Relevant model parameters are identified by scaled sensitivities. Then, Particle Swarm Optimization is applied to determine the optimal parameter values and finally, the error in prognosis is determined. We compare the predictions of the optimized models with results from a forward run of the reference model to obtain the actual prediction errors. The analyses presented here were performed calibrating the hydro-mechanical model to 31 data sets of 100 observations of varying data types. The prognosis results improve when using diversified information for calibration. However, when using several types of information, the number of observations has to be increased to be able to cover a representative part of the model domain. For an analysis with constant number of observations, a compromise between data type availability and domain coverage proves to be the best solution. Which type of calibration information contributes to the best prognoses could not be determined in advance. The error in model prognosis does not depend on the error in calibration, but on the parameter error, which unfortunately cannot be determined in inverse problems since we do not know its real value. The best prognoses were obtained independent of calibration fit. However, excellent calibration fits led to an increase in prognosis error variation. In the case of excellent fits; parameters' values came near the limits of reasonable physical values more often. To improve the prognoses reliability, the expected value of the parameters should be considered as prior information on the optimization algorithm.},

The approximate model is addressed to include the operational and surrounding condition in the assessment. The procedure is split into two stages, the training and detecting phase. During training phase, a so-called response surface is built from training data using polynomial regression and radial basis function approximation approaches. The response surface is used to detect the damage in structure during detection phase. The results show that the response surface model is able to detect moderate damage in one of bridge supports while the temperatures and train velocities are varied.},

  abstract  = {This work describes an algorithm and corresponding software for incorporating general nonlinear multiple-point equality constraints in a implicit sparse direct solver. It is shown that direct addressing of sparse matrices is possible in general circumstances, circumventing the traditional linear or binary search for introducing (generalized) constituents to a sparse matrix. Nested and arbitrarily interconnected multiple-point constraints are introduced by processing of multiplicative constituents with a built-in topological ordering of the resulting directed graph. A classification of discretization methods is performed and some re-classified problems are described and solved under this proposed perspective. The dependence relations between solution methods, algorithms and constituents becomes apparent. Fracture algorithms can be naturally casted in this framework. Solutions based on control equations are also directly incorporated as equality constraints. We show that arbitrary constituents can be used as long as the resulting directed graph is acyclic. It is also shown that graph partitions and orderings should be performed in the innermost part of the algorithm, a fact with some peculiar consequences. The core of our implicit code is described, specifically new algorithms for direct access of sparse matrices (by means of the clique structure) and general constituent processing. It is demonstrated that the graph structure of the second derivatives of the equality constraints are cliques (or pseudo-elements) and are naturally included as such. A complete algorithm is presented which allows a complete automation of equality constraints, avoiding the need of pre-sorting. Verification applications in four distinct areas are shown: single and multiple rigid body dynamics, solution control and computational fracture.},

Es stellte sich heraus, dass die Fuzzy-Methode ein geeignetes Werkzeug sein k{\"o}nnte, die Teilprozesse auf die M{\"o}glichkeit ihrer Parallelisierung hin zu untersuchen. Um diese Theorie zu testen, wurde auf den Grundlagen von Arbeiten der Professur Baubetrieb und Bauverfahren der Prozess n{\"a}her analysiert und unterst{\"u}tzend durch eigene Recherchen ein UML-Diagramm erstellt, welches als Aktivit{\"a}tsdiagramm ausgebildet wurde. Aufbauend auf diesem Ablauf und den gewonnenen Kenntnissen zur Herstellung einer Br{\"u}ckenkappe, konnten die einzelnen Prozesse zu Teilprozessen, sogenannten Bausteinen, zusammengefasst werden. Diese Bausteine sind entstanden, um die Simulation m{\"o}glich zu machen, indem der Ablauf weniger komplex wird und nur die Prozesse zu beurteilen sind, die beeinflusst bzw. in ihrer Reihenfolge bis zu einem gewissen Grad variabel sind. Eine erleichterte Interaktion mit den Bausteinen und deren {\"U}berf{\"u}hrung in ein Simulationsprogramm wurde {\"u}ber Templates realisiert. So besitzt jeder Baustein eine einheitliche Struktur. Unter anderem beinhalten die Bausteine die jeweiligen Ressourcen und Parameter, sowie die Abh{\"a}ngigkeiten der Prozesse untereinander und die zugeh{\"o}rige Priorit{\"a}t. Zur Entscheidungsfindung wurde die Fuzzylogik herangezogen und die Problemstellung der Parallelisierung zum Ziel gesetzt. Die Realisierung wurde {\"u}ber einen Entscheidungsbaum und das daraus resultierende Regelwerk erreicht. Somit ließen sich, ausgehend von einem festgelegten Prozess und durch die Fuzzifizierung der Eingangsparameter Priorit{\"a}t, Prozessdauer und Verf{\"u}gbarkeit der Ressourcen und Arbeitskr{\"a}fte, verschiedene Pfade identifizieren, allerdings nur in Verbindung mit den vorher analysierten Abh{\"a}ngigkeiten. F{\"u}r jeden der Eingangsparameter wurden so Fuzzy-Sets erstellt. {\"U}ber den Entscheidungsbaum, welcher mit den linguistischen Variablen versehen wurde, konnte {\"u}ber sogenannte "und" - Verkn{\"u}pfungen das Regelwerk aufgestellt werden. Das gek{\"u}rzte Regelwerk in dieser Arbeit beinhaltet grunds{\"a}tzlich nur die Regeln, die auch zu einer wirklichen Entscheidung f{\"u}hren. Daraus folgt, dass es m{\"o}glich ist mittels der Fuzzy-Methode eine Entscheidung dar{\"u}ber zu f{\"a}llen, ob zwei Prozesse zu parallelisieren sind oder nicht und aufgetretene Verz{\"o}gerungen wieder eingeholt werden k{\"o}nnen.},

  abstract  = {Electromagnetic wave propagation is currently present in the vast majority of situations which occur in veryday life, whether in mobile communications, DTV, satellite tracking, broadcasting, etc. Because of this the study of increasingly complex means of propagation of lectromagnetic waves has become necessary in order to optimize resources and increase the capabilities of the devices as required by the growing demand for such services. Within the electromagnetic wave propagation different parameters are considered that characterize it under various circumstances and of particular importance are the reflectance and transmittance. There are several methods or the analysis of the reflectance and transmittance such as the method of approximation by boundary condition, the plane wave expansion method (PWE), etc., but this work focuses on the WKB and SPPS methods. The implementation of the WKB method is relatively simple but is found to be relatively efficient only when working at high frequencies. The SPPS method (Spectral Parameter Powers Series) based on the theory of pseudoanalytic functions, is used to solve this problem through a new representation for solutions of Sturm Liouville equations and has recently proven to be a powerful tool to solve different boundary value and eigenvalue problems. Moreover, it has a very suitable structure for numerical implementation, which in this case took place in the Matlab software for the valuation of both conventional and turning points profiles. The comparison between the two methods allows us to obtain valuable information about their perfor mance which is useful for determining the validity and propriety of their application for solving problems where these parameters are calculated in real life applications.},

  abstract  = {This paper presents a strain smoothing procedure for the extended finite element method (XFEM). The resulting "edge-based" smoothed extended finite element method (ESm-XFEM) is tailored to linear elastic fracture mechanics and, in this context, to outperform the standard XFEM. In the XFEM, the displacement-based approximation is enriched by the Heaviside and asymptotic crack tip functions using the framework of partition of unity. This eliminates the need for the mesh alignment with the crack and re-meshing, as the crack evolves. Edge-based smoothing (ES) relies on a generalized smoothing operation over smoothing domains associated with edges of simplex meshes, and produces a softening effect leading to a close-to-exact stiffness, "super-convergence" and "ultra-accurate" solutions. The present method takes advantage of both the ES-FEM and the XFEM. Thanks to the use of strain smoothing, the subdivision of elements intersected by discontinuities and of integrating the (singular) derivatives of the approximation functions is suppressed via transforming interior integration into boundary integration. Numerical examples show that the proposed method improves significantly the accuracy of stress intensity factors and achieves a near optimal convergence rate in the energy norm even without geometrical enrichment or blending correction.},

However, applying these techniques to large complex structures like civil engineering buildings still has some limitations since these types of structures are unique and the methodologies often need a large number of specimens for reliable results. For this reason, cost and time can greatly influence the final results. Model Assisted Probability Of Detection (MAPOD) has taken its place among the ranks of damage identification techniques, especially with advances in computer capacity and modeling tools. Nevertheless, the essential condition for a successful MAPOD is having a reliable model in advance. This condition is opening the door for model assessment and model quality problems. In this work, an approach is proposed that uses Partial Models (PM) to compute the Probability Of damage Detection (POD). A simply supported beam, that can be structurally modified and tested under laboratory conditions, is taken as an example. The study includes both experimental and numerical investigations, the application of vibration-based damage detection approaches and a comparison of the results obtained based on tests and simulations. Eventually, a proposal for a methodology to assess the reliability and the robustness of the models is given.},

  abstract  = {Safety operation of important civil structures such as bridges can be estimated by using fracture analysis. Since the analytical methods are not capable of solving many complicated engineering problems, numerical methods have been increasingly adopted. In this paper, a part of isotropic material which contains a crack is considered as a partial model and the proposed model quality is evaluated. EXtended IsoGeometric Analysis (XIGA) is a new developed numerical approach [1, 2] which benefits from advantages of its origins: eXtended Finite Element Method (XFEM) and IsoGeometric Analysis (IGA). It is capable of simulating crack propagation problems with no remeshing necessity and capturing singular field at the crack tip by using the crack tip enrichment functions. Also, exact representation of geometry is possible using only few elements. XIGA has also been successfully applied for fracture analysis of cracked orthotropic bodies [3] and for simulation of curved cracks [4]. XIGA applies NURBS functions for both geometry description and solution field approximation. The drawback of NURBS functions is that local refinement cannot be defined regarding that it is based on tensorproduct constructs unless multiple patches are used which has also some limitations. In this contribution, the XIGA is further developed to make the local refinement feasible by using Tspline basis functions. Adopting a recovery based error estimator in the proposed approach for evaluation of the model quality and performing the adaptive processes is in progress. Finally, some numerical examples with available analytical solutions are investigated by the developed scheme.},

  abstract  = {New foundations for geometric algebra are proposed based upon the existing isomorphisms between geometric and matrix algebras. Each geometric algebra always has a faithful real matrix representation with a periodicity of 8. On the other hand, each matrix algebra is always embedded in a geometric algebra of a convenient dimension. The geometric product is also isomorphic to the matrix product, and many vector transformations such as rotations, axial symmetries and Lorentz transformations can be written in a form isomorphic to a similarity transformation of matrices. We collect the idea that Dirac applied to develop the relativistic electron equation when he took a basis of matrices for the geometric algebra instead of a basis of geometric vectors. Of course, this way of understanding the geometric algebra requires new definitions: the geometric vector space is defined as the algebraic subspace that generates the rest of the matrix algebra by addition and multiplication; isometries are simply defined as the similarity transformations of matrices as shown above, and finally the norm of any element of the geometric algebra is defined as the nth root of the determinant of its representative matrix of order n×n. The main idea of this proposal is an arithmetic point of view consisting of reversing the roles of matrix and geometric algebras in the sense that geometric algebra is a way of accessing, working and understanding the most fundamental conception of matrix algebra as the algebra of transformations of multilinear quantities.},

  abstract  = {Thin-walled cylindrical composite shell structures are often applied in aerospace for lighter and cheaper launcher transport system. These structures exhibit sensitivity to geometrical imperfection and are prone to buckling under axial compression. Today the design is based on NASA guidelines from the 1960's [1] using a conservative lower bound curve embodying many experimental results of that time. It is well known that the advantages and different characteristics of composites as well as the evolution of manufacturing standards are not considered apporopriately in this outdated approach. The DESICOS project was initiated to provide new design guidelines regarding all the advantages of composites and allow further weight reduction of space structures by guaranteeing a more precise and robust design. Therefore it is necessary among other things to understand how a cutout with different dimensions affects the buckling load of a thin-walled cylindrical shell structure in combination with initial geometric imperfections. This work is intended to identify a ratio between the cutout characteristic dimension (in this case the cutout diameter) and the structure characteristic dimension (in this case the cylinder radius) that can be used to tell if the buckling structure is dominated by initial imperfections or is dominated by the cutout.},

To find out which parameters are important for the laser polishing process and the surface roughness respectively and to estimate material tensions, temperature simulations and extensive polishing experiments took place. During these experiments starting and machining parameters were changed and temperatures were measured contact-free. The accuracy of thermal and mechanical simulation was improved in the case of advanced FE-analysis.},

Basically in the kernel of the complex Fourier transform the complex imaginary unit j is replaced by a square root of -1 in Cl(p,q). The Clifford Fourier transform (CFT) thus obtained generalizes previously known and applied CFTs, which replaced the complex imaginary unit j only by blades (usually pseudoscalars) squaring to -1. A major advantage of real Clifford algebra CFTs is their completely real geometric interpretation. We study (left and right) linearity of the CFT for constant multivector coefficients in Cl(p,q), translation (x-shift) and modulation (w -shift) properties, and signal dilations. We show an inversion theorem. We establish the CFT of vector differentials, partial derivatives, vector derivatives and spatial moments of the signal. We also derive Plancherel and Parseval identities as well as a general convolution theorem.},

  abstract  = {There is a continuous exacerbation of environmental problems in big cities of today's world, thereby, diminishing the quality of life in them. Of particular concern is the fact that today's megacities are evolving in the developing world without corresponding growth in the economy, infrastructure and other human development indices. As urban population continues to grow in these cities of the Global South, governing institutions are usually unable to keep pace with their social responsibilities, thus, making the issue of urban governance very critical. This is because effective and efficient urban governance is highly essential for the creation, strengthening and sustenance of governing institutions. Lagos, a mega-city of over 15.45 million people and the most populous metropolitan area on the African continent epitomizes the fundamental grave characteristics of the emerging megacities of the Global South, thereby, constituting an apt choice in understanding the emerging megacities of the next generation. Two out of every three Lagos residents live in slums and de-humanizing physical and social conditions. Many of them sleep, work, eat and cook under highway bridges, at the mercy of weather elements. This research, therefore, evaluated urban governance through housing administration in Africa's largest megacity. It examines the extent of housing problems in the city, the causal factors and the culpability of government agencies statutorily responsible for the provision, control and management of housing development in Lagos - the tenth largest city in the world. A representative geographic part of the city which manifests classic characteristics of slum life, listed by Mike Davis as the largest slum in Africa and the 6th largest in the world - Ajegunle - was adopted for case study. The research design combined rigorous literature search (desk research) with quantitative and, especially, qualitative approaches to data collection. The qualitative approach was more intensely adopted because government officials often respond to enquiries with 'official answers and data' which may not be reliable and the study had to rely on keen observation of physical traces, social interaction and personal investigation. The cross-sectional research method was adopted. Information was solicited from house-owners, building industry professionals, sociologists and officials of relevant government agencies, through research tools like questionnaires, interviews, focused group discussions and personal observations. The analysis and discussion of these field data, in conjunction with the information from the desk research gave a better understanding of the status-quo, which informed the recommendations proposed in the dissertation for mitigating the problems. The research discovered that many of the statutory housing agencies have the capacity to effectively discharge their responsibilities. However, it was also shown that corruption and abdication of responsibilities by the staff of these agencies constitute primary causes of the chasm between the anticipated lofty outcome from the laudable building regulations/bye-laws and the appalling reality. It also discovered that lack of political will and apathy on the part of successive Governments of Lagos State to the improvement of housing conditions of the poor masses are major causes of the housing debacle in Lagos. Several germane and realistic recommendations for redressing the situation were subsequently proffered. These include amongst others, the conduction of an accurate census for Lagos, in conjunction with credible international agencies, as a requisite basis for effective planning of any sort. The process of obtaining legal titles for land should also be made less cumbersome, while the housing administration process should be computerized; in order to reduce inter-personal contacts between applicants and government officials to the barest minimum, as a means of curbing the wide spread corruption in the system.},

  abstract  = {Numerical simulations in the general field of civil engineering are common for the design process of structures and/or the assessment of existing buildings. The behaviour of these structures is analytically unknown and is approximated with numerical simulation methods like the Finite Element Method (FEM). Therefore the real structure is transferred into a global model (GM, e.g. concrete bridge) with a wide range of sub models (partial models PM, e.g. material modelling, creep). These partial models are coupled together to predict the behaviour of the observed structure (GM) under different conditions. The engineer needs to decide which models are suitable for computing realistically and efficiently the physical processes determining the structural behaviour. Theoretical knowledge along with the experience from prior design processes will influence this model selection decision. It is thus often a qualitative selection of different models. The goal of this paper is to present a quantitative evaluation of the global model quality according to the simulation of a bridge subject to direct loading (dead load, traffic) and indirect loading (temperature), which induce restraint effects. The model quality can be separately investigated for each partial model and also for the coupled partial models in a global structural model. Probabilistic simulations are necessary for the evaluation of these model qualities by using Uncertainty and Sensitivity Analysis. The method is applied to the simulation of a semi-integral concrete bridge with a monolithic connection between the superstructure and the piers, and elastomeric bearings at the abutments. The results show that the evaluation of global model quality is strongly dependent on the sensitivity of the considered partial models and their related quantitative prediction quality. This method is not only a relative comparison between different models, but also a quantitative representation of model quality using probabilistic simulation methods, which can support the process of model selection for numerical simulations in research and practice.},

  abstract  = {In cities people live together in neighbourhoods. Here they can find the infrastructure they need, starting with shops for the daily purpose to the life-cycle based infrastructures like kindergartens or nursing homes. But not all neighbourhoods are identical. The infrastructure mixture varies from neighbourhood to neighbourhood, but different people have different needs which can change e.g. based on the life cycle situation or their affiliation to a specific milieu. We can assume that a person or family tries to settle in a specific neighbourhood that satisfies their needs. So, if the residents are happy with a neighbourhood, we can further assume that this neighbourhood satisfies their needs. The socio-oeconomic panel (SOEP) of the German Institute for Economy (DIW) is a survey that investigates the economic structure of the German population. Every four years one part of this survey includes questions about what infrastructures can be found in the respondents neighbourhood and the satisfaction of the respondent with their neighbourhood. Further, it is possible to add a milieu estimation for each respondent or household. This gives us the possibility to analyse the typical neighbourhoods in German cities as well as the infrastructure profiles of the different milieus. Therefore, we take the environment variables from the dataset and recode them into a binary variable - whether an infrastructure is available or not. According to Faust (2005), these sets can also be understood, as a network of actors in a neighbourhood, which share two, three or more infrastructures. Like these networks, this neighbourhood network can also be visualized as a bipartite affiliation network and therefore analysed using correspondence analysis. We will show how a neighbourhood analysis will benefit from an upstream correspondence analysis and how this could be done. We will also present and discuss the results of such an analysis.},

  abstract  = {Bridge vibration due to traffic loading has been a subject of extensive research in the last decades. The focus of such research has been to develop solution algorithms and investigate responses or behaviors of interest. However, proving the quality and reliability of the model output in structural engineering has become a topic of increasing importance. Therefore, this study is an attempt to extend concepts of uncertainty and sensitivity analyses to assess the dynamic response of a coupled model in bridge engineering considering time-dependent vehicular loading. A setting for the sensitivity analysis is proposed, which enables performing the sensitivity analysis considering random stochastic processes. The classical and proposed sensitivity settings are used to identify the relevant input parameters and models that have the most influence on the variance of the dynamic response. The sensitivity analysis exercises the model itself and extracts results without the need for measurements or reference solutions; however, it does not offer a means of ranking the coupled models studied. Therefore, concepts of total uncertainty are employed to rank the coupled models studied according to their fitness in describing the dynamic problem. The proposed procedures are applied in two examples to assess the output of coupled subsystems and coupled partial models in bridge engineering considering the passage of a heavy vehicle at various speeds.},

  abstract  = {Bridge vibration due to traffic loading has been subject of extensive research in the last decades. Such studies are concerned with deriving solutions for the bridge-vehicle interaction (BVI) and analyzing the dynamic responses considering randomness of the coupled model's (BVI) input parameters and randomness of road unevenness. This study goes further to examine the effects of such randomness of input parameters and processes on the variance of dynamic responses in quantitative measures. The input parameters examined in the sensitivity analysis are, stiffness and damping of vehicle's suspension system, axle spacing, and stiffness and damping of bridge. This study also examines the effects of the initial excitation of a vehicle on the influences of the considered input parameters. Variance based sensitivity analysis is often applied to deterministic models. However, the models for the dynamic problem is a stochastic one due to the simulations of the random processes. Thus, a setting using a joint meta-model; one for the mean response and other for the dispersion of the response is developed. The joint model is developed within the framework of Generalized Linear Models (GLM). An enhancement of the GLM procedure is suggested and tested; this enhancement incorporates Moving Least Squares (MLS) approximation algorithms in the fitting of the mean component of the joint model. The sensitivity analysis is then performed on the joint-model developed for the dynamic responses caused by BVI.},

  abstract  = {The process of analysis and design in structural engineering requires the consideration of different partial models, for example loading, structural materials, structural elements, and analysis types. The various partial models are combined by coupling several of their components. Due to the large number of available partial models describing similar phenomena, many different model combinations are possible to simulate the same aspects of a structure. The challenging task of an engineer is to select a model combination that ensures a sufficient, reliable prognosis. In order to achieve this reliable prognosis of the overall structural behavior, a high individual quality of the partial models and an adequate coupling of the partial models is required. Several methodologies have been proposed to evaluate the quality of partial models for their intended application, but a detailed study of the coupling quality is still lacking. This paper proposes a new approach to assess the coupling quality of partial models in a quantitative manner. The approach is based on the consistency of the coupled data and applies for uni- and bidirectional coupled partial models. Furthermore, the influence of the coupling quality on the output quantities of the partial models is considered. The functionality of the algorithm and the effect of the coupling quality are demonstrated using an example of coupled partial models in structural engineering.},

  abstract  = {This thesis explores how architecture aids in the performance of open-ended narratives by engaging both actively and passively with memory, i.e. remembering and forgetting. I argue that architecture old and new stems from specific cultural and social forms, and is dictated by processes of remembering and forgetting. It is through interaction (between inhabitant and object) that architecture is given innate meanings within an urban environment that makes its role in the interplay one of investigative interest. To enable the study of this performance, I develop a framework based on various theoretical paradigms to investigate three broad questions: 1) How does one study the performance of memory and forgetting through architecture in dynamic urban landscapes? 2) Is there a way to identify markers and elements within the urban environment that enable such a study? 3) What is the role that urban form plays within this framework and does the transformation of urban form imply the transformation of memory and forgetting? The developed framework is applied to a macro (an urban level study of Bangalore, India) and micro level study (a singular or object level study of Stari Most/ Old Bridge, Mostar, BiH), to analyse the performance of remembering and forgetting in various urban spheres through interaction with architecture and form. By means of observations, archival research, qualitative mapping, drawings and narrative interviews, the study demonstrates that certain sites and characteristics of architecture enable the performance of remembering and the questioning of forgetting by embodying features that support this act. Combining theory and empirical studies this thesis is an attempt to elucidate on the processes through which remembering and forgetting is initiated and experienced through architectural forms. The thesis argues for recognising the potential of architecture as one that embodies and supports the performance of memory and forgetting, by acting as an auratic contact zone.},

The bearing capacities of high-rise structures with various dimple geometries and various cover parameters were determined with respect to specified areas of the trunk. Dependent relationships are represented graphically for the decrease in bearing capacity of a cover with respect to dimples.

Zum anderen tr{\"a}gt er dem Erfordernis nach einem st{\"a}dtebaulichen Gegen{\"u}ber f{\"u}r das Regierungsgeb{\"a}ude Rechnung, welches damit in den Verbund der kulturellen Einrichtungen auf dem T{\"o}{\"o}l{\"o}nlahti Gel{\"a}nde aufgenommen wird. Dar{\"u}ber hinaus belebt er eine Besonderheit von Helsinki. Zu Beginn des 20. Jahrhunderts bestand die Notwendigkeit den Hafen an das Schienennetz anzubinden. Da der Stadtkern bereits sehr dicht bebaut war, wurde ein Eisenbahnring entlang der K{\"u}ste, einmal um das Stadtzentrum herum gebaut. Seitdem die Verbindung stillgelegt wurde liegt dieser Ring brach, was nun die große Chance bietet, eine kreuzungsfreien Rad- und Fußweg zu etablieren, der durch den Entwurf eines Mobilityhubs geschlossen w{\"u}rde. In der vorliegenden Brosch{\"u}re werden die st{\"a}dtebaulichen Rahmenbedingungen, die Analyse der gegenw{\"a}rtigen Situation und der eigentliche Entwurfsprozess, der zu dieser L{\"o}sung f{\"u}hrte dokumentiert.},

  abstract  = {Many structures in different engineering applications suffer from cracking. In order to make reliable prognosis about the serviceability of those structures it is of utmost importance to identify cracks as precisely as possible by non-destructive testing. A novel approach (XIGA), which combines the Isogeometric Analysis (IGA) and the Extended Finite Element Method (XFEM) is used for the forward problem, namely the analysis of a cracked material, see [1]. Applying the NURBS (Non-Uniform Rational B-Spline) based approach from IGA together with the XFEM allows to describe effectively arbitrarily shaped cracks and avoids the necessity of remeshing during the crack identification problem. We want to exploit these advantages for the inverse problem of detecting existing cracks by non-destructive testing, see e.g. [2]. The quality of the reconstructed cracks however depends on two major issues, namely the quality of the measured data (measurement error) and the discretization of the crack model. The first one will be taken into account by applying regularizing methods with a posteriori stopping criteria. The second one is critical in the sense that too few degrees of freedom, i.e. the number of control points of the NURBS, do not allow for a precise description of the crack. An increased number of control points, however, increases the number of unknowns in the inverse analysis and intensifies the ill-posedness. The trade-off between accuracy and stability is aimed to be found by applying an inverse multilevel algorithm [3, 4] where the identification is started with short knot vectors which successively will be enlarged during the identification process.},

  abstract  = {It is well known that complex quaternion analysis plays an important role in the study of higher order boundary value problems of mathematical physics. Following the ideas given for real quaternion analysis, the paper deals with certain orthogonal decompositions of the complex quaternion Hilbert space into its subspaces of null solutions of Dirac type operator with an arbitrary complex potential. We then apply them to consider related boundary value problems, and to prove the existence and uniqueness as well as the explicit representation formulae of the underlying solutions.},

  abstract  = {This paper is focused on the first numerical tests for coupling between analytical solution and finite element method on the example of one problem of fracture mechanics. The calculations were done according to ideas proposed in [1]. The analytical solutions are constructed by using an orthogonal basis of holomorphic and anti-holomorphic functions. For coupling with finite element method the special elements are constructed by using the trigonometric interpolation theorem.},
