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.}, subject = {Mediendesign}, language = {en} } @misc{Froehlich, type = {Master Thesis}, author = {Fr{\"o}hlich, Jan}, title = {On systematic approaches for interpreted information transfer of inspection data from bridge models to structural analysis}, doi = {10.25643/bauhaus-universitaet.4131}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20200416-41310}, school = {Bauhaus-Universit{\"a}t Weimar}, pages = {82}, abstract = {In conjunction with the improved methods of monitoring damage and degradation processes, the interest in reliability assessment of reinforced concrete bridges is increasing in recent years. Automated imagebased inspections of the structural surface provide valuable data to extract quantitative information about deteriorations, such as crack patterns. However, the knowledge gain results from processing this information in a structural context, i.e. relating the damage artifacts to building components. This way, transformation to structural analysis is enabled. This approach sets two further requirements: availability of structural bridge information and a standardized storage for interoperability with subsequent analysis tools. Since the involved large datasets are only efficiently processed in an automated manner, the implementation of the complete workflow from damage and building data to structural analysis is targeted in this work. First, domain concepts are derived from the back-end tasks: structural analysis, damage modeling, and life-cycle assessment. The common interoperability format, the Industry Foundation Class (IFC), and processes in these domains are further assessed. The need for usercontrolled interpretation steps is identified and the developed prototype thus allows interaction at subsequent model stages. The latter has the advantage that interpretation steps can be individually separated into either a structural analysis or a damage information model or a combination of both. This approach to damage information processing from the perspective of structural analysis is then validated in different case studies.}, subject = {Br{\"u}ckenbau}, language = {en} } @misc{Theiler, type = {Master Thesis}, author = {Theiler, Michael}, title = {Interaktive Visualisierung von Qualit{\"a}tsdefiziten komplexer Bauwerksinformationsmodelle auf Basis der Industry Foundation Classes (IFC) in einer webbasierten Umgebung}, doi = {10.25643/bauhaus-universitaet.1786}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20121214-17869}, school = {Bauhaus-Universit{\"a}t Weimar}, pages = {93}, abstract = {Der inhaltlichen Qualit{\"a}tssicherung von Bauwerksinformationsmodellen (BIM) kommt im Zuge einer stetig wachsenden Nutzung der verwendeten BIM f{\"u}r unterschiedliche Anwen-dungsf{\"a}lle eine große Bedeutung zu.

For the relevant class, I conducted an conceptual case study in Istanbul, Beyoglu District, with the intention of analysing the perception of the space by urban sound. During the summer 2015 I recorded various sounds of different spatial settings and developed the analysis by comparing the situations. By that time, I realized the inherent property of the sound as a medium for our perception in urban context. In the 2015-2016 winter semester, I participated in the master class of the architectural project, named 'Build Allegory', which was given by Prof. Dipl.-Ing. Heike B{\"u}ttner. The project was situated in Berlin Westkreuz, AVUS north curve, on the highway and was originally a race track from 1921. In this context, the aim of my project was to answer various questions, main of which was, how does the architectural form shape the sound of the place? And, how does the sound of the place shape the architectural from? Since the place is still serving mainly to the vehicles, although the function has differed, the sound objects and the context have remained. Through the existence of contextual references, I started with creating a computational tool for analysing the acoustic characteristics of this urban setting, which is fundamentally providing results as the sound cloud, driven from the sound ray tracing method. Regarding to this soundscape analysis method, which I developed, this computational tool assisted me to find an optimum reciprocal relation between architecture and sound. Since I have been working on soundscape in the context of architecture, urban situations, public life and public space, I was determined to produce a comprehensive research in this field and propound the hypothesis; the existence of the reciprocity between the social behaviours in public space and the sound landscape. In which extent does this reciprocity exist? What are the effects of the public life on the sonic configurations of the space and the other way around?}, subject = {{\"O}ffentlicher Raum}, language = {en} } @misc{Kavrakov, type = {Master Thesis}, author = {Kavrakov, Igor}, title = {Structural Optimization of Composite Cross-Sections and Elements using Energy Methods}, doi = {10.25643/bauhaus-universitaet.3959}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20190815-39593}, school = {Bauhaus-Universit{\"a}t Weimar}, pages = {96}, abstract = {Structural optimization has gained considerable attention in the design of structural engineering structures, especially in the preliminary phase. This study introduces an unconventional approach for structural optimization by utilizing the Energy method with Integral Material Behavior (EIM), based on the Lagrange's principle of minimum potential energy. An automated two-level optimization search process is proposed, which integrates the EIM, as an alternative method for nonlinear structural analysis, and the bilevel optimization. The proposed procedure secures the equilibrium through minimizing the potential energy on one level, and on a higher level, a design objective function. For this, the most robust strategy of bilevel optimization, the nested method is used. The function of the potential energy is investigated along with its instabilities for physical nonlinear analysis through principle examples, by which the advantages and limitations using this method are reviewed. Furthermore, optimization algorithms are discussed. A numerical fully functional code is developed for nonlinear cross section, element and 2D frame analysis, utilizing different finite elements and is verified against existing EIM programs. As a proof of concept, the method is applied on selected examples using this code on cross section and element level. For the former one a comparison is made with standard procedure, by employing the equilibrium equations within the constrains. The validation of the element level was proven by a theoretical solution of an arch bridge and finally, a truss bridge is optimized. Most of the principle examples are chosen to be adequate for the everyday engineering practice, to demonstrate the effectiveness of the proposed method. This study implies that with further development, this method could become just as competitive as the conventional structural optimization techniques using the Finite Element Method.}, subject = {Strukturoptimierung}, language = {en} } @misc{Lang, type = {Master Thesis}, author = {Lang, Kevin}, title = {Argument Search with Voice Assistants}, doi = {10.25643/bauhaus-universitaet.3935}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20190617-39353}, school = {Bauhaus-Universit{\"a}t Weimar}, pages = {100}, abstract = {The need for finding persuasive arguments can arise in a variety of domains such as politics, finance, marketing or personal entertainment. In these domains, there is a demand to make decisions by oneself or to convince somebody about a specific topic. To obtain a conclusion, one has to search thoroughly different sources in literature and on the web to compare various arguments. Voice interfaces, in form of smartphone applications or smart speakers, present the user with natural conversations in a comfortable way to make search requests in contrast to a traditional search interface with keyboard and display. Benefits and obstacles of such a new interface are analyzed by conducting two studies. The first one consists of a survey for analyzing the target group with questions about situations, motivations, and possible demanding features. The latter one is a wizard-of-oz experiment to investigate possible queries on how a user formulates requests to such a novel system. The results indicate that a search interface with conversational abilities can build a helpful assistant, but to satisfy the demands of a broader audience some additional information retrieval and visualization features need to be implemented.}, subject = {Amazon Alexa}, language = {en} }
