TY - THES A1 - Schloth, Sebastian T1 - Beitrag zum Einfluss bogenförmiger Deichlinien mit innenliegenden vollkommenen Dichtungssystemen auf die Grundwasserströmung N2 - Bei einigen bogenförmig verlaufenden Deichlinien ist es erforderlich, die Standsicherheit des Deiches mit Hilfe innenliegender vollkommener Dichtungssysteme zu verbessern. Diese Art der Deichsanierung hat jedoch Auswirkungen auf die Grundwasserströmung. Im Rahmen der wasserrechtlichen Genehmigungsverfahren ist der zu erwartende Aufstau bzw. die Absenkung des Grundwassers darzulegen. Die Zielsetzung dieser Masterarbeit ist es, hierzu einen Beitrag herauszuarbeiten. Dazu werden im ersten Schritt die erforderlichen Grundlagen erläutert. In einem zweiten Schritt werden mit wasserbaulichen/wasserwirtschaftlichen Methoden der Flussverlauf des Rheins in Nordrhein-Westfalen anhand von Kartenmaterial ausgewertet und mögliche Bogenformen ermittelt. Im dritten Schritt werden für diese Bogenformen unter Variation verschiedener Parameter numerische Berechnungen durchgeführt. Die erhaltenen Ergebnisse werden unter Berücksichtigung der vorhandenen analytischen Berechnungsverfahren, mit dem Ziel der Ableitung eines Berechnungsansatzes bzw. von Anwendungsdiagrammen, bewertet.

Zur Diskussion über den Umgang mit verschmähten Bauwerken N2 - Für die einen also „Bausünde“, für die anderen ein erhaltenswertes Bauwerk – wie geht man damit um? Für wen gilt wann etwas als „Bausünde“ und wann als erhaltenswert, welche Ziele werden damit verfolgt und Konzepte aufgezeigt? Inwieweit spielen beispielsweise Aspekte wie Ästhetik, Funktionalität oder der allgemeine gesellschaftliche Kontext bzw. Wandel sowie das jeweils aktuelle und bauzeitliche planerische Leitbild bzw. Verständnis eine Rolle bei der Verwendung des Begriffs und den Umgang für konkrete Bauwerke? Und inwieweit steht der Erhaltungswert bzw. eine Denkmalwürdigkeit damit im Verhältnis und wie kann damit planerisch umgegangen werden? Der Diskussion über den Umgang mit verschmähten Bauwerken will sich die vorliegende Abschlussarbeit nähern. Als Bauwerke werden hierbei sowohl Gebäude und Plätze als auch zur Erinnerung gesetzte Objekte wie Statuen verstanden.

It focuses on two species of tropical plants: Ficus elastica and Hevea brasiliensis. Geographically their native habitat is very distant from each other, but they connect by European influence through the exploitation of latex. The many forms and outcomes from this work manifest the attempt of the artist to create an association between a common household plant, the origin of its name, and the source of rubber. As a ghostly connective tissue, the latex surrounds reconstructed history, old prints, live plants, and drawings, accepting the material's capacity to both erase and preserve the past.

This project was an attempt to develop a learning tool for studying astrological concepts as connected to observational astronomy. The premise that astrology and observational astronomy were once inseparable from each other in ancient times guided the conceptualization of this tool as an interactive planetarium. The main references were existing software and applications for visualization in astrology and astronomy. Professional astrology teachers were consulted in order to understand better the state of astrological teaching and learning, as well as existing tools and practice. Horoskopos was built using the Unity3D development interface, which is based on the C# programming language. It also relied on the Swiss Ephemeris coding interface from Astrodienst. The development process was experimental and many of the needed skills were developed as needed. Usability tests were performed as new features were added to the interface. The final version of Horoskopos is fully usable, with many interactive visualization features and a defined visual identity. It was validated together with professional astrologers for its effectiveness in concept and visualization.

Consequently, the modelling of found damages based on those images in a streamlined automated manner becomes increasingly important, not just for saving time and money spent on updating the model to include the latest information gathered through each inspection, but also to easily visualise them, provide all stakeholders involved with a comprehensive digital representation containing all the necessary information to fully understand the structure’s current condition, keep track of any progressing deterioration, estimate the reduced load bearing capacity of the damaged element in the model or simulate the propagation of cracks to make well-informed decisions interactively and facilitate maintenance actions that optimally extend the service life of the structure. Though significant progress has been recently made in information modelling of damages, the current devised methods for the geometrical modelling approach are cumbersome and time consuming to implement in a full-scale model. For crack damages, an approach for a feasible automated image-based modelling is proposed utilising neural networks, classical computer vision and computational geometry techniques with the aim of creating valid shapes to be introduced into the information model, including related semantic properties and attributes from inspection data (e.g., width, depth, length, date, etc.). The creation of such models opens the door for further possible uses ranging from more accurate structural analysis possibilities to simulation of damage propagation in model elements, estimating deterioration rates and allows for better documentation, data sharing, and realistic visualisation of damages in a 3D model.

Smart mobility strategies, such as shared mobility and mobility stations, represent some of the solutions to promote changes in travel behavior. Despite its beneficial impacts, however, the implementation of such infrastructure is criticized for not contributing to current urban issues, as well as often disregarding knowledge about urban space and its functioning. In this context, the Smarter Together, a joint research and innovation project funded through the European Union program H2020, was implemented. The project selected three lighthouse cities to test and upscale innovative solutions: Vienna, Munich, and Lyon. This master thesis presents the main characteristics of the mobility stations systems implemented in Vienna and Munich in the scope of the project Smarter Together. Its main goal is to share what can be learned from their experiences while approaching critically the concept of smart cities. This master thesis identifies important aspects to take into account when planning, implementing, and operating mobility stations, and provides an understanding of smart cities and smart mobility that goes beyond the adoption of technology. Several methods were combined for the development of this master thesis, such as quantitative secondary data, observational studies, application of survey forms, explorative expert interviews, and literature review. This work has demonstrated that the Smarter Together has a cutting-edge scope and contributed greatly to research and innovation, by creating living laboratories to test the application of technology in the urban environment. However, from the perspective of the mobility stations assessment, many caveats were made. In short, many lessons could be learned and are presented throughout this work aiming at contributing to the improvement of the mobility stations implemented in the project areas in Munich and Vienna, as well as for inspiring other cities in Europe and worldwide.

Social movement and the effects of Internet on urban space N2 - Advances in information and communication technologies such as the Internet have driven a great transformation in the interactions between individuals and the urban environment. As the use of the Internet in cities becomes more intense and diverse, there is also a restructuring of urban space, which is experienced by groups in society in various ways, according to the specificity of each context. Accordingly, large Internet companies have emerged as new players in the processes of urbanization, either through partnerships with the public administration or through various services offered directly to urban residents. Once these corporations are key actors in the digitalization of urban services, their operations can affect the patterns of urban inequality and generate a series of new struggles over the production of space. Interested in analyzing this phenomena from the perspective of civil society, the present Master Thesis examined a social movement that prevented Google to settle a new startup campus in the district of Kreuzberg, in Berlin. By asking why Google was not welcome in that context, this study also sought to understand how internet, as well as its main operators, has affected everyday life in the city. Thus, besides analyzing the movement, I investigated the particularities of the urban context where it arose and the elements that distinguish the mobilization’s opponent. In pursuit of an interdisciplinary approach, I analyzed and discussed the results of empirical research in dialogue with critical theories in the fields of urban studies and the Internet, with emphasis on Castells' definitions of urban social movements and network society (1983, 2009, 2015), Couldry's and Mejias' (2019) idea of data colonialism, Lefèbvre's (1991, 1996) concepts of abstract space and the right to the city, as well as Zuboff's (2019) theory of surveillance capitalism. The case at hand has exposed that Google plays a prominent role in the way the Internet has been developed and deployed in cities. From the perspective accessed, the current appropriation of Internet technologies has been detrimental to individual autonomy and has contributed to intensifying existing inequalities in the city. The alternative vision to this relies mainly on the promotion of decentralized solidarity networks.
