And what does a global pandemic mean for the city and its people? Until 2020, hardly anyone has probably asked themselves this question. But the sudden changes in public life, with standoff rules and restrictions on movement, have changed the way urban spaces are used. What demands will be placed on urban spaces and structures after the pandemic? To what extent do new forms of organization of everyday life affect urban processes? Findings from university teaching and a national winter school open a critical discussion on urban planning during and after the pandemic. Aspiring planners, architects and designers have expressed their ideas and demands for a mixed-use and climate-friendly city.Million, Angela;Bentlin, Felix;Jansen, Hendrik;Velazco-Londono, Jose M.;Kataikko-Grigoleit, Päivihttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3228-7/Fri, 19 Nov 2021 00:00:00 +0100Elements of Dynamic and 2-SAT Programming: Paths, Trees, and Cutshttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3210-2/<div>This thesis presents faster (in terms of worst-case running times) exact algorithms for special cases of graph problems through dynamic programming and 2-SAT programming. Dynamic programming describes the procedure of breaking down a problem recursively into overlapping subproblems, that is, subproblems with common subsubproblems. Given optimal solutions to these subproblems, the dynamic program then combines them into an optimal solution for the original problem. 2-SAT programming refers to the procedure of reducing a problem to a set of 2-SAT formulas, that is, boolean formulas in conjunctive normal form in which each clause contains at most two literals.</div><div>Computing whether such a formula is satisfiable (and computing a satisfying truth assignment, if one exists) takes linear time in the formula length. Hence, when satisfying truth assignments to some 2-SAT formulas correspond to a solution of the original problem and all formulas can be computed efficiently, that is, in polynomial time in the input size of the original problem, then the original problem can be solved in polynomial time. We next describe our main results.</div><div>Diameter asks for the maximal distance between any two vertices in a given undirected graph. It is arguably among the most fundamental graph parameters. We provide both positive and negative parameterized results for distance-from-triviality-type parameters and parameter combinations that were observed to be small in real-world applications.</div><div>In Length-Bounded Cut, we search for a bounded-size set of edges that intersects all paths between two given vertices of at most some given length. We confirm a conjecture from the literature by providing a polynomial-time algorithm for proper interval graphs which is based on dynamic programming.</div><div>k-Disjoint Shortest Paths is the problem of finding (vertex-)disjoint paths between given vertex terminals such that each of these paths is a shortest path between the respective terminals. Its complexity for constant k > 2 has been an open problem for over 20 years. Using dynamic programming, we show that k-Disjoint Shortest Paths can be solved in polynomial time for each constant k.</div><div>The problem Tree Containment asks whether a phylogenetic tree T is contained in a phylogenetic network N. A phylogenetic network (or tree) is a leaf-labeled single-source directed acyclic graph (or tree) in which each vertex has in-degree at most one or out-degree at most one. The problem stems from computational biology in the context of the tree of life (the history of speciation). We introduce a particular variant that resembles certain types of uncertainty in the input. We show that if each leaf label occurs at most twice in a phylogenetic tree N, then the problem can be solved in polynomial time and if labels can occur up to three times, then the problem becomes NP-hard.</div><div>Lastly, Reachable Object is the problem of deciding whether there is a sequence of rational trades of objects among agents such that a given agent can obtain a certain object. A rational trade is a swap of objects between two agents where both agents profit from the swap, that is, they receive objects they prefer over the objects they trade away. This problem can be seen as a natural generalization of the well-known and well-studied Housing Market problem where the agents are arranged in a graph and only neighboring agents can trade objects. We prove a dichotomy result that states that the problem is polynomial-time solvable if each agent prefers at most two objects over its initially held object and it is NP-hard if each agent prefers at most three objects over its initially held object. We also provide a polynomial-time 2-SAT program for the case where the graph of agents is a cycle.</div>Bentert, Matthiashttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3210-2/Thu, 18 Nov 2021 00:00:00 +0100Das virtuelle Digitalgebäudehttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3222-5/The publication relates to a digital learning system for building construction and building technology.

Organizations measure and manage direct water use at their premises but usually neglect the indirect water use associated with global supply chains – even though the latter can be higher by several orders of magnitude.</div><div><br></div><div>As of 2015, there was no standardized life-cycle-based approach for analysing the water consumption of an organization. Against this background, the BMBF funded research project “Water Footprint for Organizations – Local Measures in Global Supply Chains (WELLE)” has been launched by TU Berlin, Evonik, German Copper Institute, Neoperl, thinkstep and Volkswagen. The project aims to support organizations in determining their complete Organizational Water Footprint, identifying local hotspots in global supply chains and taking action to reduce their water use and mitigate water stress at critical basins.</div><div><br></div><div>Within the WELLE project a method for analysing an Organizational Water Footprint has been developed, which analyses an organization’s water use and resulting local impacts throughout its entire value chain. In other words, the Organizational Water Footprint considers not only the direct water use at production facilities, but also the water used indirectly for energy generation and raw material production (upstream in the supply chain) as well as water use during the use and end-of-life phases of products (downstream). The Organizational Water Footprint method builds on two environmental assessment frameworks which have been identified as suitable for the purpose of this project: Water Footprint (ISO 14046, 2014 and Organizational Life Cycle Assessment (UNEP 2015). To support stakeholders in conducting Organizational Water Footprint studies, this guidance document was developed, which presents the method in a clear and concise way by illustrating each step with a practical example.</div><div><br></div><div>By analysing their Water Footprints, organizations can determine water use and resulting local impacts at premises and “beyond the fence” along global supply chains.

Many engineering tasks require open-world resolutions to support multi-actor collaboration, coping with approximate models, providing effective engineer-computer interaction, search in multi-dimensional solution spaces, accommodating uncertainty, including specialist domain knowledge, performing sensor-data interpretation and dealing with incomplete knowledge. While results from computer science provide much initial support for resolution, adaptation is unavoidable and most importantly, feedback from addressing engineering challenges drives fundamental computer-science research.

This publication presents various aspects concerning the connection of `Wissenschaft´ – including both science and humanties – and Architecture demonstrating the significance of the former to the latter and vice versa. In reflecting their interrelation, the perspectives of the different contributions are directed either to the past, to the present situation or to the future of an insitutionalised `Architecturewissenschaft´.Neubert, Christine;Froschauer, Eva Maria;Weckherlin, Gernot;Bovelet, Jan;Almarza Anwandter, Juan;Dürfeld, Michael;Schneider, Peter I.https://verlag.tu-berlin.de/en/produkt/978-3-7983-3203-4/Fri, 25 Jun 2021 00:00:00 +0200Home not Shelter! – Ein modularer Gemeinschaftsraumhttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3192-1/The Home not Shelter! Plug-in is a usage-neutral room module that spatially expands the precarious living situation of refugees in emergency shelters and makes offers that go beyond mere accommodation. In the plug-in, refugees can get actively involved in a collaborative process and with professional support. The pavilion is to be planned in the immediate vicinity of existing refugee shelters and is adaptable in size. If necessary, it can change its location and be relocated to other workplaces. The "Home not Shelter! -Plug-in" can be an open space, event space and meeting place where new and old neighbors meet, exchange ideas and get to know each other. It can either be docked directly to the accommodation or set up in its vicinity. The plug-in has the potential to reproduce, expand, and multiply itself and to adapt to various locations and uses. The high aesthetic and architectural quality serves as a signal that 'refugee architecture' does not have to correspond to the precarious living situation of those affected.Hacke, Max;Pasel, Ralfhttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3192-1/Tue, 08 Jun 2021 00:00:00 +0200Stereo vision-based road condition monitoringhttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3205-8/<div>When planning road construction measures, it is essential to have up-to-date information on road conditions. If this information is not to be obtained manually, it is currently obtained using laser scanners mounted on mobile mapping vehicles, which can measure the 3D road profile. However, a large number of mobile mapping vehicles would be necessary to record an entire road network on a regular basis. Since 2D road damages can be found automatically on monocular camera images, the idea was born to use a stereo camera system to capture the 3D profile of roads. With stereo camera systems, it would be possible to equip a large number of vehicles and regularly collect data from large road networks.</div><div>In this thesis, the potential applications of a stereo camera system for measuring road profiles, which is mounted behind the windshield of a vehicle, are investigated. Since this requires a calibration of the stereo camera system, but the effort for the user should be kept low, the camera self-calibration for this application is also examined.</div><div>3D reconstruction from stereoscopic images is a well-studied topic, but its application on road surfaces with little and repetitive textures requires special algorithms. For this reason, a new stereo method was developed. It is based on the plane-sweep approach in combination with semi-global matching. It was tested with different measures for pixel comparison. Furthermore, the plane-sweep approach was implemented in a neural network that solves the stereo correspondence problem in a single step. It uses the stereoscopic images as input and provides an elevation image as output.</div><div>A completely new approach was developed for the self-calibration of mono cameras and stereo camera systems. Previous methods search for feature points in several images of the same scene. The points are matched between the images and used for the calibration. In contrast to these methods, the proposed method uses feature maps instead of feature points to compare multiple views of one and the same plane. To estimate the unknown parameters, the backpropagation algorithm is used together with the gradient descent method.</div><div>The measurements obtained by stereoscopic image processing were compared with those obtained by industrial laser scanners. They show that both measurements are very close to each other and that a stereoscopic camera system is in principle suitable for capturing the surface profile of a road.</div><div>Experiments show that the proposed self-calibration method is capable of estimating all parameters of a complex camera model, including lens distortion, with high precision.</div>Brunken, Haukehttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3205-8/Wed, 12 May 2021 00:00:00 +0200PLATE – Product lifetimes and the environmenthttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3125-9/The current systems of consumption and production cause long-lasting social-ecological damage and a fundamental change seems inevitable, if livelihoods of present and future generations are to be preserved. The lifetimes of products and their performance concerning reliability, functionality, re-usability and recyclability are core issues in the transformation from a linear to a more sustainable circular economy. While discussions on product lifetimes have been going on for a number of years, the topic has come to the forefront of current (political, scientific & societal) debates due to its interconnectedness with a number of recent prominent movements, such as the circular economy, ecodesign and collaborative consumption. The 3rd international PLATE conference (Product Lifetimes And The Environment), held from 18-20 June 2019 in Berlin, Germany, addressed product lifetimes in the context of sustainability. The proceedings of this conference present a great variety of significant research on how to enable more sustainable practices of designing, producing, using, re-pur-posing and recycling products and on how to assess the sustainability of these endeavours. The authors work in inter- and transdisciplinary teams that operate at the crossroads of engineering, design, social sciences and environmental sciences.Jaeger-Erben, Melanie;Nissen, Nils F.https://verlag.tu-berlin.de/en/produkt/978-3-7983-3125-9/Tue, 11 May 2021 00:00:00 +0200Verschleißprognose zur zuverlässigkeitsorientierten Regelung für trockene Reibkupplungenhttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3196-9/<div>In the development of modern vehicles demands on reliability increasing continuously. Formerly it was acceptable to visit a workshop in the event of damage. However, damage detection and repairement at an early stage will be expected in future. Predictive maintenance strategies are needed to reduce the risks associated with unexpected downtime and financial losses.</div><div>In this work, a predictive maintenance strategy by a reliability-oriented control is developed, which is based on wear estimation and prognosis. The development of the required methods is based on the example of a dry friction clutch, which represents an essential component in the classic powertrain. To implement the defined objective, a physical thermal model of the friction clutch is first derived. Subsequently, a wear model is developed on the basis of the theoretically expected wear behavior. The thermal model and the wear model are identified by experimental investigations on a transmission test bench. Based on the wear model, a remaining useful life prediction is developed. This prediction determines future wear from future stress by using the wear model. Therefore, future stress is extrapolated from past data. Finally, the predicted lifetime is used as an input variable of the reliability-oriented control. The reliability-oriented control consists of a model-predictive vehicle launch control and a superimposed fuzzy control. It adapts continuously the operating behavior of the clutch control to guarantee a required system lifetime.</div>Strommenger, Danielhttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3196-9/Mon, 10 May 2021 00:00:00 +0200Bibliothekserlaubnisse im Urheberrechthttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3188-4/The book deals in detail with the requirements of existing copyright exceptions, for libraries in German statutory copyright law.

A creative triad, which over a period of two years has jointly committed itself to the utopia of enabling a synthesis of sustainable economy, healthy environment and a just society. The project Mind the Fungi (“Achtung Pilze”) is a Citizen Science research project, which resulted from the cooperation of the Departments of Applied and Molecular Microbiology and Bioprocess Engineering of the TU Berlin and the art and research platform Art Laboratory Berlin. It was intended to provide citizens with an opportunity for scientific collaboration. On the one hand, the project was intended to give a broad public an understanding of the importance of fungal biotechnology for a sustainable future and, on the other hand, to establish a research network here at the TU Berlin, in which, among other things, novel fungus-based biomaterials were to be researched with Citizen Scientists.

The results obtained from various university seminars and a European summer school form the basis for a crisis manuscript, while serving to review the planning and design activities in different European cities and regions. For the first time ever, a network of students from the urban planning and design departments at 19 European universities have defined common requirements for crisis-resistant and people-friendly urban planning in Europe: On the one hand, crisis-related experiences act as catalysts for fundamental social, economic, and ecological changes, and, on the other hand, they accelerate changes that are already underway with regard to urban development policies. The crisis and border situations explored in this joint investigation extend beyond the mere operating principles of European cities and regions. In fact, as an endurance test and didactic example, they provide a guide for crisis-proof urban renewal in Europe. They lead the way in building a bridge between the European architecture and planning disciplines to create vibrant border landscapes.Million, Angela;Bentlin, Felix;Höfler, Jürgenhttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3200-3-2/Thu, 01 Apr 2021 00:00:00 +0200Konzeptverfahren als Instrument einer gemeinwohlorientierten Stadtentwicklunghttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3174-7/Who should profit from urban planning? An increasing number of stakeholders currently demand that planning policy leads to added value for the entire urban society and not just for individual groups: Designing for the common good! One instrument of public real estate policy that negotiates the common good could be a conceptual allocation of public property (Konzeptverfahren). This instrument allows cities to allocate their land based on the quality of the idea for development and use instead of price-based bidding. In public invitations to tender, municipalities define a set of criteria that applicants can or must meet. The aim of this publication is to evaluate the orientation of such tenders towards the common good using a list of criteria compiled from the following existing assessments: The Federal Building Code (Baugesetzbuch); the city yield (Stadtrendite); a proposed federal policy to support not-for-profit housing companies (Wohngemeinnützigkeit); the Common Good Balance Sheet (Gemeinwohlökonomie); the Better-Life-Index (Wohlstandsforschung) and the common good criteria as defined in the federal tax code (Gemeinnützigkeit nach Abgabenordnung). Although there may be some variations in definitions of common good, at the core of these assessments are social criteria, ecological sustainability, and opportunities for participation. Beside these dominant categories, each assessment is supplemented by less common criteria which are grouped into six additional categories, giving an overview of how the common good is currently defined. This paper examines 28 invitations to tender based on the conceptual allocation of public property (Konzeptausschreibungen). Of these 28 invitations, each from a different German city, it was found that all contained, to some extent, the criteria for forming common good. As such, these tenders can be considered as supporting the common good. This script finds, however, that the categories participation, education and health should resonate more strongly in future tenders. The instrument (Konzeptverfahren) offers municipalities the opportunity to set development goals that are based on local needs and public interest criteria. But, as the comparison shows, there are significant differences between tendering procedures. Therefore, it should not be concluded that tendering based on the conceptual allocation of public property guarantees public interest-oriented urban development.Gennies, Monahttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3174-7/Wed, 03 Mar 2021 00:00:00 +0100Update for all – Lehrpraxis für eine faire Digitalisierunghttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3194-5/<div>This bibliography was written as a part of the research project „Fix-IT.

There is little scientific research in the practical world of architecture about the impact of built structures on city spaces. At the same time, architects design and form our environment, thereby making a significant impact on society. The aim of this research is to work from an architectural point of view to fill this gap. The research focuses on the interface of theory and practice. The relation between architecture and society is especially distinct and readable in the city. Changes in the structure and image of the city are extremely dynamic. On the basis of a specific typology—the shopping mall—the relation of the city’s image and architecture will be analyzed. The facade as the surface of the built structure, plays an outstanding role in this relationship.</div><div>Trade was a main starting point in forming cities. In the beginning, trade and the city were inseparable. Consumer society and the connected architecture typology were subject to major transformations in the past centuries. To understand the current typology of the shopping mall, the past typologies as representatives of their eras are reviewed. These are the market square, the market hall, the passage, the department store, and the current typology shopping mall. The history of the shopping mall starts with Victor Gruen, a Jew who immigrated to America in 1938. Missing the European street style of shopping, he invented the first shopping mall as an open concept in the suburbs of North America.</div><div>The shopping mall—reimported from America to Germany—was the first typology to leave the city center and move to the suburbs. Soon realizing that the function of trade did not need the city anymore, whereas the city did need trade, developers moved the shopping mall back to the inner city, initially with an unchanged concept and layout. Facing e-commerce as a strong new competitor, developers are forced to rethink the shopping mall’s typology to maintain its strength in the market. This challenge provides an opportunity for architecture to be recognized and become relevant in the development of the new shopping-mall typology. The phenomenon of the consumer society and the cohesive trade architecture of the 21st century is of current relevance.</div><div>Berlin offers a wide range of characteristics as a research field, such as its multicentral structure with its diverse and strong trade architecture history. The field research analyzes how large-scale inner city shopping malls affect their immediate surrounding space and form the city image and what role the facade plays in this context. The case studies are Alexa and LP12 Mall of Berlin. Both case studies stand out by being newly established in the last 10 years, being located in the historic center of Berlin, and having a sales area of over 50.000 m2. The resulting research will initiate and contribute to an architectural-scientific discourse.</div><div>It is beneficial to use the rich trade typology history for the creation of a new shopping mall typology and to take part in the discussion. In the historic development of the typology, the facade doubled and left a closed cover outside, where the city is dependent for permeability. The cover doesn’t function as a transition interface between the public and private space anymore. Market-based economic goals (no permeability in the facades) face public collective interests (permeable facades). The architectural experience is a unique offline feature and must be seen as a benefit for the city and developer. The current practice to invite architects only for facade competitions underlies the disputatious process of looking at the inside and the outside of buildings separately. The development from the impermeable facade (Alexa) to the perforated facade (LP12 Mall of Berlin) indicates that if the inside does not change simultaneously, the user of the space will not acknowledge the opening and use it in that sense. The activation of the city space has to be produced through lively permeable interfaces that communicate between the inside and outside.</div>Otten, Leoniehttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3190-7/Fri, 29 Jan 2021 00:00:00 +0100Conceptualizing and capturing digital transformation‘s customer value – a logistics and supply chain management perspectivehttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3177-8/This thesis aims to add knowledge that contributes to answering the question of how digital transformation technologies can contribute to increasing customer value in logistics and supply chain management (L&SCM), and how manufacturing companies can mindfully use them. The output of the thesis is an architectural framework that proposes performance components, approaches and methodologies that can help in capturing this customer value.<br> To build the basis for such a framework, this research first deduces and presents the underlying definition of digital transformation and describes its potential for, as well as current barriers for its application in, L&SCM.<br> The study uses a systematic literature review to identify nine underlying digital transformation technology bundles. These are: auto-identification technologies;information and communication technologies;the cloud;cyber physical systems;analytics;distributed ledger;automation technologies;augmented and virtual reality;and additive manufacturing.<br> These technologies served as inputs for a nominal group technique workshop aiming to conceptualize the dimensions of customer value based on the technologies. The derived dimensions are information disclosure, time, product/production, service/assistance, quality, choice options, and planning. Based on these findings, this thesis presents an impact assessment for customer-based L&SCM performance. The three-plus-one customer value propositions are availability, servitization, co-creation, and cognition as enhancement.<br> Expert interviews provide the data for the architectural framework for capturing customer value based on digital transformation technologies in L&SCM. The six dimensions covered are the customer value proposition;the value portfolio;scope of collaboration;human resource management and organization;performance management;as well as the (re-)adjusting value assessment.<br> The main scientific contribution lies in conceptualizing the customer value for L&SCM based on digital transformation technologies whereas the architectural framework constitutes the main practical contributions.Junge, Anna Lisahttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3177-8/Fri, 15 Jan 2021 00:00:00 +0100Beitrag zur Analyse des Eigenspannungsverhaltens von Composite-Hochdruckspeichern mit metallischem Linerhttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3179-2/<div>When designing high-pressure vessels, the use of fibre reinforced plastics becomes of increasing importance due to their high specific strength properties. However, a high variation in material properties and manufacturing parameters as well as variable load scenarios during service life; make it very difficult to give accurate lifetime predictions and to define reasonable inspection periods. The aim of this work is to get detailed information on the residual stress behaviour in the context of the presented light-weight structure aging process. The research of this work focuses on pressure vessels which consist of an inner aluminium liner surrounded by carbon fibre reinforced plastics (type III). The lifetime of the structure is limited by the load cycle sensitivity of the metal and its residual stress condition. To be able to give more accurate lifetime predictions in the future, a lifetime analysis of residual stresses is executed to deliver input data for an appropriate structural durability model.</div><div>The central point of this research is an artificial aging testing program of type III pressure vessels, during which changes in residual stress conditions are measured and analysed continuously. In the beginning, mechanical peak loads as well as load-structure behaviour are obtained through preliminary tests and simulations. Next, for residual stress measurements, the underlying parameters had to be determined and tested. A focus is set on the development of a non-destructive measurement method based on an experimental modal analysis. Through experimental studies, the intensity and scatter of the initial residual stress condition of manufactured pressure vessels was obtained first. Then a significantly reduced residual stress condition was obtained when measuring 15-year-old specimen. Accompanying the artificial aging program, changes of residual stresses, altered material characteristics and strain behaviour of the tested structures were monitored. According to measurement results, an increased state of residual stresses due to artificial aging was determined. In a last step, the captured residual stress behaviour was implemented into a developed structural durability model. The used analytical model was verified by the number of load cycles until failure which have been obtained experimentally. By simulating cases of various load conditions, it is shown that the accuracy of lifetime prediction can be increased when considering variable states of residual stresses.</div>John, Sebastianhttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3179-2/Wed, 13 Jan 2021 00:00:00 +0100Mind the Fungihttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3168-6/<div><b>Paperback available: </b><a href="https://verlag.tu-berlin.de/en/produkt/978-3-7983-3202-7/">https://verlag.tu-berlin.de/en/produkt/978-3-7983-3202-7/</a><br></div><div>This book reports on the bundling of the creativity engines science and art and how a living triad of science, art and society can be forged from this. A creative triad, which over a period of two years has jointly committed itself to the utopia of enabling a synthesis of sustainable economy, healthy environment and a just society. The project Mind the Fungi (“Achtung Pilze”) is a Citizen Science research project, which resulted from the cooperation of the Departments of Applied and Molecular Microbiology and Bioprocess Engineering of the TU Berlin and the art and research platform Art Laboratory Berlin. It was intended to provide citizens with an opportunity for scientific collaboration. On the one hand, the project was intended to give a broad public an understanding of the importance of fungal biotechnology for a sustainable future and, on the other hand, to establish a research network here at the TU Berlin, in which, among other things, novel fungus-based biomaterials were to be researched with Citizen Scientists. The scientific and artistic paths in the Mind-the-Fungi project, which we followed together with the public from 2018 to 2020, including the Art &Design Residencies, can now be traced in text and images in this book.</div>Volpato, Alessandro;Schubert, Bastian;Schmidt, Bertram;Weber, Birke;Lutz, Christian de;Peluso, Fara;Pohl, Karsten;Cerimi, Kustrim;Neubauer, Peter;Rapp, Regine;Junne, Stefan;Schubert, Theresa;Meyer, Vera;Zakeri, Zakiehhttps://verlag.tu-berlin.de/en/produkt/978-3-7983-3168-6/Wed, 23 Dec 2020 00:00:00 +0100
