Paul Otlets Utopie der Wissensvisualisierung N2 - Gegen Ende des 19. Jahrhunderts geriet das Dokumentationswesen in eine Krise: wie lässt sich das kulturelle Wissen nachhaltiger organisieren? Paul Otlet (1868–1944), ein belgischer Industriellenerbe und studierter Rechtsanwalt, entwickelte zusammen mit Henri La Fontaine ab 1895 ein Ordnungs- und Klassifikationssystem, das das millionenfach publizierte „Weltwissen“ dokumentieren sollte. Otlets Anspruch war die Schaffung eines „Instrument d’ubiquité“, das zur „Hyper-Intelligence“ führen sollte. Jahrzehnte vor Web und Wikis weisen diese Ideen auf eine globale Vernetzung des Wissens hin. Der vorliegende Titel erinnert an den Pionier Paul Otlet mit einer ausführlichen Einleitung von Frank Hartmann (Bauhaus-Universität Weimar), Beiträgen von W. Boyd Rayward (University of Illinois), Charles van den Heuvel (Königlich Niederländische Akademie der Wissenschaften) und Wouter Van Acker (Universität Gent).

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of composites as well as the evolution of manufacturing standards are not considered apporopriately in this outdated approach.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.

With laser radiation it is possible to finish many outlines or geometries on quartz glass surfaces in the shortest possible time. It’s a fact that the temperature developing while polishing determines the reachable surface smoothing and, as a negative result, causes material tensions. 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.

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.

Significant frequency shifts are observed for the z breathing mode around θ=0° and 60°, while the frequency is a constant in a wide range [8,55]°.

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.

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.

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. N2 - Brückenschwingungen infolge von Verkehrslasten sind seit mehreren Jahrzehnten Gegenstand intensiver Forschung. Im Fokus stand hierbei im Besonderen die Entwicklung von Lösungsalgorithmen zur Ermittlung des dynamischen Bauwerkverhaltens. Begleitet ist diese Entwicklung von der Frage nach der Qualität und Zuverlässigkeit dieser Modelle für den Gebrauch im konstruktiven Ingenieurbau. In diesem Zusammenhang werden in der vorliegenden Arbeit Konzepte der Unsicherheits- und Sensitivitätsanalyse erweitert, um das dynamische Bauwerkverhalten unter Berücksichtigung transienter Fahrzeuglasten bei gekoppelten Modellen des Brückenbaus zu bewerten. Bestehende Sensitivitätsanalysen werden ergänzt, um diese auch unter Berücksichtigung von stochastischen Prozessen durchführen zu können. Die klassische und die erweiterte Methode werden angewandt, um relevante Eingangsparameter sowie Partialmodelle mit wesentlichem Einfluss auf die Varianz der dynamischen Strukturantwort zu identifizieren. Die mit Hilfe der Sensitivitätsanalyse ermittelbaren Kennzahlen können ohne Bezug zu einer Referenzlösung in die Modellbewertung einfließen, allerdings ist es nicht möglich, die Modelle hinsichtlich der realitätsnahen Abbildung des dynamischen Problems zu bewerten. Um dies zu ermöglichen, wurden Konzepte der Gesamtunsicherheit verwendet. Die vorgestellten Methoden wurden auf zwei Beispiele angewandt, um die Ergebnisse von gekoppelten Subsystemen und gekoppelten Partialmodellen des Brückenbaus zu evaluieren. Hierbei handelt es sich um die Überfahrt von schweren Fahrzeugen mit verschiedenen Geschwindigkeiten.

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.

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.

Die Bewertung erfolgt erneut basierend auf einer Unsicherheitsanalyse sowie alternativ mittels Modellselektion nach Bayes. Weiterhin wird eine auf Graphentheorie und Sensitivitätsanalysen basierende Methode zur Bewertung von gekoppelten Partialmodellen entwickelt. Damit wird der Einfluss eines Partialmodells auf das Verhalten einer globalen Tragstruktur quantifiziert, Interaktionen von Partialmodellen festgestellt und ein Maß für die Qualität eines Gesamtmodells ermittelt. N2 - The goal of this doctoral thesis is the development of methods for the evaluation of the prediction quality of concrete creep models. The methods are distinguished into two scenarios: the evaluation with and without experimental data about the creep behavior of concrete. The model quality is quantified by the total uncertainty of the predicted creep compliance. The uncertainty of the creep prognosis without using measurement data is quantified by an uncertainty analysis taking into account the parameter correlation. When experimental data is considered the stochastic properties of the creep model parameters are found by means of Bayesian Updating. The evaluation is once more based on an uncertainty analysis or, alternatively, applying Bayesian model selection. Further, an assessment method of coupled partial models based on graph theory and sensitivity analysis is developed. Therewith, the influence of classes of partial models on the global model response is quantified, interactions of partial models are detected, and a measure for the quality of the global model is derived.
