Research has been carried out on the modal identification of rather simple truss structures. So far, less attention has been given to complex three-dimensional truss structures. This work develops a vibration-based methodology for determining modal information of three-dimensional space truss structures. The method uses a relatively complex space truss structure for its verification. Numerical modelling of the system gives modal information about the expected vibration behaviour. The identification process involves closely spaced modes that are characterised by local and global vibration mechanisms. To distinguish between local and global vibrations of the system, modal strain energies are used as an indicator. The experimental validation, which incorporated a modal analysis employing the stochastic subspace identification method, has confirmed that considering relatively high model orders is required to identify specific mode shapes. Especially in the case of the determination of local deformation modes of space truss members, higher model orders have to be taken into account than in the modal identification of most other types of structures.}, subject = {Fachwerkbau}, language = {en} } @article{AbrahamczykUzair, author = {Abrahamczyk, Lars and Uzair, Aanis}, title = {On the use of climate models for estimating the non-stationary characteristic values of climatic actions in civil engineering practice}, series = {Frontiers in Built Environment}, volume = {2023}, journal = {Frontiers in Built Environment}, number = {volume 9, article 1108328}, publisher = {Frontier Media}, address = {Lausanne}, doi = {10.3389/fbuil.2023.1108328}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20230524-63751}, pages = {1 -- 9}, abstract = {The characteristic values of climatic actions in current structural design codes are based on a specified probability of exceedance during the design working life of a structure.

In current debates, allegations of censorship surface primarily in cases where the handling of a certain heritage constructs is subjected to critical evaluation, or on the contrary, needs to be protected from criticism or even destruction.

Still, information needs that concern forming opinions on a controversial topic or making a decision remain a challenge for search engines. Since they are optimized to retrieve satisfying answers, search engines might emphasize a specific stance on a controversial topic in their ranking, amplifying bias in society in an undesired way. Argument retrieval systems support users in forming opinions about controversial topics by retrieving arguments for a given query. In this thesis, we address challenges in argument retrieval systems that concern integrating them in search engines, developing generalizable argument mining approaches, and enabling frame-guided delivery of arguments. Adapting argument retrieval systems to search engines should start by identifying and analyzing information needs that look for arguments. To identify questions that look for arguments we develop a two-step annotation scheme that first identifies whether the context of a question is controversial, and if so, assigns it one of several question types: factual, method, and argumentative. Using this annotation scheme, we create a question dataset from the logs of a major search engine and use it to analyze the characteristics of argumentative questions. The analysis shows that the proportion of argumentative questions on controversial topics is substantial and that they mainly ask for reasons and predictions. The dataset is further used to develop a classifier to uniquely map questions to the question types, reaching a convincing F1-score of 0.78. While the web offers an invaluable source of argumentative content to respond to argumentative questions, it is characterized by multiple genres (e.g., news articles and social fora). Exploiting the web as a source of arguments relies on developing argument mining approaches that generalize over genre. To this end, we approach the problem of how to extract argument units in a genre-robust way. Our experiments on argument unit segmentation show that transfer across genres is rather hard to achieve using existing sequence-to-sequence models. Another property of text which argument mining approaches should generalize over is topic. Since new topics appear daily on which argument mining approaches are not trained, argument mining approaches should be developed in a topic-generalizable way. Towards this goal, we analyze the coverage of 31 argument corpora across topics using three topic ontologies. The analysis shows that the topics covered by existing argument corpora are biased toward a small subset of easily accessible controversial topics, hinting at the inability of existing approaches to generalize across topics. In addition to corpus construction standards, fostering topic generalizability requires a careful formulation of argument mining tasks. Same side stance classification is a reformulation of stance classification that makes it less dependent on the topic. First experiments on this task show promising results in generalizing across topics. To be effective at persuading their audience, users of an argument retrieval system should select arguments from the retrieved results based on what frame they emphasize of a controversial topic. An open challenge is to develop an approach to identify the frames of an argument. To this end, we define a frame as a subset of arguments that share an aspect. We operationalize this model via an approach that identifies and removes the topic of arguments before clustering them into frames. We evaluate the approach on a dataset that covers 12,326 frames and show that identifying the topic of an argument and removing it helps to identify its frames.}, subject = {Informatik}, language = {en} } @article{AlemuHabteLahmeretal., author = {Alemu, Yohannes L. and Habte, Bedilu and Lahmer, Tom and Urgessa, Girum}, title = {Topologically preoptimized ground structure (TPOGS) for the optimization of 3D RC buildings}, series = {Asian Journal of Civil Engineering}, volume = {2023}, journal = {Asian Journal of Civil Engineering}, publisher = {Springer International Publishing}, address = {Cham}, doi = {10.1007/s42107-023-00640-2}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20230517-63677}, pages = {1 -- 11}, abstract = {As an optimization that starts from a randomly selected structure generally does not guarantee reasonable optimality, the use of a systemic approach, named the ground structure, is widely accepted in steel-made truss and frame structural design.

Such a one-time fixed layout trend, in addition to its lack of a systemic approach, does not necessarily guarantee optimality.

A multiobjective function at the floor optimization stage and a single objective function at the frame optimization stage are considered. A particle swarm optimization (PSO) method is employed for selecting the optimal ground structure.

Due to the phase difference between the vibrations of the cores and the structure, the cores counteract the vibration of the structure. The core-coating inclusions are randomly distributed in concrete similar to standard aggregates. This mixture is referred to as metaconcrete. The main goal of this work is to validate the ability of the inclusions to suppress mechanical vibration through laboratory experiments. For this purpose, two small-scale metaconcrete beams were cast and tested. In a free vibration test, the metaconcrete beams exhibited a larger damping ratio compared to a similar beam cast from conventional concrete.

They have remarkable mechanical behavior which is characterized by many phenomena, but most noticeably their fluid-like in-plane behavior and solid-like out-of-plane behavior. Vesicles have been studied in the context of discrete models, such as Molecular Dynamics, Monte Carlo methods, Dissipative Particle Dynamics, and Brownian Dynamics. Those methods, however, tend to have high computational costs, which limited their uses for studying atomistic details. In order to broaden the scope of this research, we resort to the continuum models, where the atomistic details of the vesicles are neglected, and the focus shifts to the overall morphological evolution. Under the umbrella of continuum models, vesicles morphology has been studied extensively. However, most of those studies were limited to the mechanical response of vesicles by considering only the bending energy and aiming for the solution by minimizing the total energy of the system. Most of the literature is divided between two geometrical representation methods; the sharp interface methods and the diffusive interface methods. Both of those methods track the boundaries and interfaces implicitly. In this research, we focus our attention on solving two non-trivial problems. In the first one, we study a constrained Willmore problem coupled with an electrical field, and in the second one, we investigate the hydrodynamics of a vesicle doublet suspended in an external viscous fluid flow. For the first problem, we solve a constrained Willmore problem coupled with an electrical field using isogeometric analysis to study the morphological evolution of vesicles subjected to static electrical fields. The model comprises two phases, the lipid bilayer, and the electrolyte. This two-phase problem is modeled using the phase-field method, which is a subclass of the diffusive interface methods mentioned earlier. The bending, flexoelectric, and dielectric energies of the model are reformulated using the phase-field parameter. A modified Augmented-Lagrangian (ALM) approach was used to satisfy the constraints while maintaining numerical stability and a relatively large time step. This approach guarantees the satisfaction of the constraints at each time step over the entire temporal domain. In the second problem, we study the hydrodynamics of vesicle doublet suspended in an external viscous fluid flow. Vesicles in this part of the research are also modeled using the phase-field model. The bending energy and energies associated with enforcing the global volume and area are considered. In addition, the local inextensibility condition is ensured by introducing an additional equation to the system. To prevent the vesicles from numerically overlapping, we deploy an interaction energy definition to maintain a short-range repulsion between the vesicles. The fluid flow is modeled using the incompressible Navier-Stokes equations and the vesicle evolution in time is modeled using two advection equations describing the process of advecting each vesicle by the fluid flow. To overcome the velocity-pressure saddle point system, we apply the Residual-Based Variational MultiScale (RBVMS) method to the Navier-Stokes equations and solve the coupled systems using isogeometric analysis. We study vesicle doublet hydrodynamics in shear flow, planar extensional flow, and parabolic flow under various configurations and boundary conditions. The results reveal several interesting points about the electrodynamics and hydrodynamics responses of single vesicles and vesicle doublets. But first, it can be seen that isogeometric analysis as a numerical tool has the ability to model and solve 4th-order PDEs in a primal variational framework at extreme efficiency and accuracy due to the abilities embedded within the NURBS functions without the need to reduce the order of the PDE by creating an intermediate environment. Refinement whether by knot insertion, order increasing or both is far easier to obtain than traditional mesh-based methods. Given the wide variety of phenomena in natural sciences and engineering that are mathematically modeled by high-order PDEs, the isogeometric analysis is among the most robust methods to address such problems as the basis functions can easily attain high global continuity. On the applicational side, we study the vesicle morphological evolution based on the electromechanical liquid-crystal model in 3D settings. This model describing the evolution of vesicles is composed of time-dependent, highly nonlinear, high-order PDEs, which are nontrivial to solve. Solving this problem requires robust numerical methods, such as isogeometric analysis. We concluded that the vesicle tends to deform under increasing magnitudes of electric fields from the original sphere shape to an oblate-like shape. This evolution is affected by many factors and requires fine-tuning of several parameters, mainly the regularization parameter which controls the thickness of the diffusive interface width. But it is most affected by the method used for enforcing the constraints. The penalty method in presence of an electrical field tends to lock on the initial phase-field and prevent any evolution while a modified version of the ALM has proven to be sufficiently stable and accurate to let the phase-field evolve while satisfying the constraints over time at each time step. We show additionally the effect of including the flexoelectric nature of the Biomembranes in the computation and how it affects the shape evolution as well as the effect of having different conductivity ratios. All the examples were solved based on a staggered scheme, which reduces the computational cost significantly. For the second part of the research, we consider vesicle doublet suspended in a shear flow, in a planar extensional flow, and in a parabolic flow. When the vesicle doublet is suspended in a shear flow, it can either slip past each other or slide on top of each other based on the value of the vertical displacement, that is the vertical distance between the center of masses between the two vesicles, and the velocity profile applied. When the vesicle doublet is suspended in a planar extensional flow in a configuration that resembles a junction, the time in which both vesicles separate depends largely on the value of the vertical displacement after displacing as much fluid from between the two vesicles. However, when the vesicles are suspended in a tubular channel with a parabolic fluid flow, they develop a parachute-like shape upon converging towards each other before exiting the computational domain from the predetermined outlets. This shape however is affected largely by the height of the tubular channel in which the vesicle is suspended. The velocity essential boundary conditions are imposed weakly and strongly. The weak implementation of the boundary conditions was used when the velocity profile was defined on the entire boundary, while the strong implementation was used when the velocity profile was defined on a part of the boundary. The strong implementation of the essential boundary conditions was done by selectively applying it to the predetermined set of elements in a parallel-based code. This allowed us to simulate vesicle hydrodynamics in a computational domain with multiple inlets and outlets. We also investigate the hydrodynamics of oblate-like shape vesicles in a parabolic flow. This work has been done in 2D configuration because of the immense computational load resulting from a large number of degrees of freedom, but we are actively seeking to expand it to 3D settings and test a broader set of parameters and geometrical configurations.}, subject = {Isogeometrische Analyse}, language = {en} } @article{BapirAbrahamczykWichtmannetal., author = {Bapir, Baban and Abrahamczyk, Lars and Wichtmann, Torsten and Prada-Sarmiento, Luis Felipe}, title = {Soil-structure interaction: A state-of-the-art review of modeling techniques and studies on seismic response of building structures}, series = {Frontiers in Built Environment}, volume = {2023}, journal = {Frontiers in Built Environment}, number = {Volume 9}, editor = {Ozturk, Baki}, publisher = {Frontiers Media}, address = {Lausanne}, doi = {10.3389/fbuil.2023.1120351}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20230206-49190}, pages = {1 -- 17}, abstract = {The present article aims to provide an overview of the consequences of dynamic soil-structure interaction (SSI) on building structures and the available modelling techniques to resolve SSI problems.

Hence, this article seeks to analyse the perception of the industrial heritage in the Vogtland region, located alongside the border of three German federal states and the Czech Republic. It inquires as to the perception of the industrial heritage by the local population and related potential future narrations. Based on spontaneous and explorative interviews with local people as an empirical base, a discrepancy between the perception of the tangible and intangible dimensions of the industrial heritage can be observed. On the one hand, the tangible heritage like older factories and production complexes are seen as a functional legacy and an "eyesore" narrative is attributed to them. On the other hand, people often reference the personal and familial connection to the industry and highlight its importance for the historical development and the wealth of the region.

We analyse the way in which two German 'climate emergency municipalities' translate conflicts of post-fossil transformation into concrete political and planning strategies. Although more than 2,200 authorities around the world have already declared a climate emergency, research on the impact of these resolutions on the political orientation of municipalities is very limited. Our research focus is on the (potentially agonistic) treatment of conflicts in planning. We argue that in times of a socio-ecological crisis, success in conflict resolution cannot refer to appeasement and depoliticisation. Instead, we propose a framework of five criteria, based on critical theory on ecomodern strategies, planning processes and degrowth. Thus, this practice-related and explorative paper connects empirical insights from the German cities of Constance and Berlin with an innovative normative framework. The findings tell a complex story of an, at least partial, admission of the failure of previous climate mitigation strategies, a lack of social institutions of limits, an instrumental relation to nature and a disregard for social injustices. The paper discusses how municipalities, in the context of ongoing tensions over the post-fossil transformation in Germany, on the one hand hold on to business-as-usual approaches, but on the other hand also set political impulses for change.}, subject = {Stadtentwicklung}, language = {de} } @article{Coenen, author = {Coenen, Ekkehard}, title = {Anti-Gewalttrainings, Gewaltwissen und die institutionelle Erzeugung gewaltbefreiter Subjekte}, series = {Soziale Passagen}, volume = {2023}, journal = {Soziale Passagen}, publisher = {VS, Verl. f{\"u}r Sozialwissenschaften/GWV-Fachverlag}, address = {Wiesbaden}, doi = {10.1007/s12592-023-00453-9}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20230720-64104}, pages = {1 -- 16}, abstract = {Dieser Beitrag fragt danach, wie Wissen {\"u}ber Gewalt in Anti-Gewalttrainings produziert, vermittelt und sozial wirkm{\"a}chtig wird.

To this day, the now defunct industrial site occupies a large section of physical el-Quseir and plays a key role in its identity. In this article, we explore the impact of the company's successive industrialization and deindustrialization based on archival research, interviews, and mapping. By tracing physical changes on-site and in the city of el-Quseir from the founding of its phosphate industry until today, as well as the historical and current interactions of citizens with the industrial facilities, we hope to better understand the "cluster value" of the industrial plant in quotidian life and the effect of the vacuum left behind after the termination of production. As machinery and buildings are slowly eroding in the absence of expressed interest by the former Italian and current Egyptian owners, we aim to discuss the relationship between the citizens and their el-Quseir phosphate plant as a crucial element of its heritage value at the local level.}, subject = {{\"A}gypten}, language = {en} } @phdthesis{Dief, author = {Dief, Shaima}, title = {Ancient Egyptian Hybrid Deities in Visual Form as Mediator in Cultural Transmission}, doi = {10.25643/bauhaus-universitaet.4933}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20230220-49337}, school = {Bauhaus-Universit{\"a}t Weimar}, pages = {170}, abstract = {The most fundamental understating of hybridization methodology takes the form of stable but dynamic notions, accumulated over time in the memory of individuals. Schematized and abstracted, the hybrids representation needs to be reproduced and reused in order to reconstruct and bring back other memories. Reinvented, or reused hybrids can support getting access to social, traditional, religious understanding of nations. In this manner, they take the form of the messenger / the mediator an innate, equivalent to the use of mental places in the art of memory. We remember mythology in order to remember other things. From individual memory perspective, or group collective memory, the act of recollection is assumed to be an individual act, biologically based in the brain, but by definition conditioned by social collectives. Following Halbwachs, this thesis does not recognize a dichotomy between individual and collective memory as two different types of remembering. Conversely, the collective is thought of as inherent to individual thought, questioning perspectives that regard individual recollection as isolated from social settings. The individual places himself in relation to the group and makes use of the collective frameworks of thought when he localizes and reconstructs the past, whether in private or in social settings. The frameworks of social relations, of time, and of space are constructs originating in social interaction and distributed in the memory of the group members. The individual has his own perspective on the collective frameworks of the group, and the group's collective frameworks can be regarded as a common denominator of the individual outlooks on the framework. In acts of remembering, the individual may actualize the depicted symbols in memory, but he could also employ precepts from the environment. The latter have been referred to as material or external frameworks of memory, suggesting their similar role as catalysts for processes of remembrance such as that of the hybrids in my paintings. It is only with reference to the hybrids, who work as messengers / mediators with a dual nature, that communicate between the past and the present, the internal and external space, that individual memory and group memory is in focus. The exhibition at the Egyptian museum in Leipzig is my practical method to create a communicative memory, using hybrids as mediators in cultural transimission, as when the act refers to informal and everyday situations in which group members informally search for the past, it takes place in the communicative 162 memory. As explained in chapter one, the exhibition at the Egyptian museum in Leipzig is an act of remembering in search for the past with support of my paintings, which then can considered as part of the cultural memory. In addition to the theoretical framework summarized above, I have applied my hypothesis practically in the form of the public exhibition, and shared the methodology with public audience from Cairo / Egypt and Leipzig / German in the form of visual art workshops and open discussions. I have also suggested an analyzed description of the meaning of hybrids in my artwork as mediators and messengers for the purpose of cultural transmission, as well as in relation to other artists' work and use of a similar concept. By using my hybrid creatures in my visual artwork, I am creating a bridge, mediators to represent both the past and the present, what we remember of the past, and how we understand the past. It is as explained in chapter two; that the hybridization methodology in terms of double membership represented in different cultures -Cairo / Egypt and Leipzig / Germany- can provide a framework which allows artistic discussions and could be individually interpreted, so individual cultures / individual memory can become transparent without losing their identities and turn into communicative memory. This transmission through the hybridization theoretical approech was explicitly clarified with the support of Kr{\"a}mer's hypothesis. The practical attempt was examined by creating a relationship between the witness -me as an artist- and the audience -the exhibition visitors-, to cross space and time, not to bridge differences, rather to represent the contrasts transparently. The Kin-making proposition is adopted by many academics and scholars in modern society and theoretical research; the topic was represented in the roots of the ancient Egyptian mindset and supported theoretically by similar understandings such as Haraway's definition of kin-making. The practical implementation of kin- making can be observed in many of my artwork and was analyzed visually and artistically in chapter three. My practical project outcome tested success by using hybrids in my paintings as mediators, it opened a communicative artistic discussion. This methodology gave a possible path of communication through paintings / visual analyses, and offered relativity through image self-interpretation.}, subject = {Kollektives Ged{\"a}chtnis}, language = {en} }
