Theorisation has delved into the types of leadership and, more recently, the activities performed by leaders. However, comparative research on leadership and detection of any changes over time is scant. Our paper attends to these tasks by looking at the activities of two German-speaking far-right leaders. For many years, Christian Worch was one of the most active and influential neo-Nazi leaders in Germany, communicating much of his activity and strategy in the mid-2000s through a regular circular (Rundbriefe). Similarly, Martin Sellner, both as leader of the Identitarian movement and independent activist, today exercises an outsized role in the German-speaking far-right scene, including through his regular publications in the magazines Compact and Sezession. Our paper uses data of Worch's and Sellner's writings, scraped from webpages and gathered from archives, in a mixed-methods comparative design to identify the tasks performed by these leaders, and how frequently. Quantitative text analysis techniques guide the qualitative evaluation of leaders' activities and reveal shifts - and continuities - in far-right movement leadership. The paper thereby contributes to scholarship on an important aspect of contemporary far-right movements as well as broader social movement literature on the topic of leadership.}, subject = {Rechtsradikalismus}, language = {en} } @techreport{GreilSchwarzStein2018, author = {Greil, Stefan and Schwarz, Christian and Stein, Stefan}, title = {Fairness and the Arm's Length Principle in a Digital Economy}, number = {42}, address = {D{\"u}sseldorf}, issn = {2365-3361}, doi = {10.20385/2365-3361/2018.42}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-12029}, year = {2018}, abstract = {The OECD Base Erosion Profit Shifting (BEPS) Initiative as well as the current fairness oriented public discussion regarding the taxation of digital business models highlight the importance and complexity of the arm's length principle.

Our model predicts that a multinational firm follows the fundamental paradigm of international taxation, i.e. the arm's length principle, to properly incentivize internal agents involved in the production of a digital good. However, with inequity averse tax authorities, we find that tax authorities "prefer" a more equal distribution of profits compared to the arm's length allocation.

They rated 6.594 situations regarding the soundscape standard dimensions, perceived loudness, and the saliency of its sound components and evaluated situational variables such as state affect, perceived control, activity, and location. To complement these subject-centered data, we additionally crowdsourced object-centered data by having participants make binaural measurements of each indoor soundscape at their homes using a low-(self-)noise recorder. These recordings were used to compute (psycho-)acoustical indices such as the energetically averaged loudness level, the A-weighted energetically averaged equivalent continuous sound pressure level, and the A-weighted five-percent exceedance level.

The most promising concepts are Organic Rankine Cycles (ORC) and Steam Rankine Cycles (SRC). In previous work of the Center of Innovative Energy Systems, D{\"u}sseldorf (Germany), the technical and economic feasibility of a low pressure SRC has been investigated and the advantages in comparison to organic Rankine cycles are highlighted. A distinctive feature of the cycle is the use of the ICE coolant heat for evaporation, which limits the cycles maximum steam pressure to values below atmospheric pressure. This work presents first results of a test rig with data reconciliation according to DIN 2048 to validate the simulation results and design calculations. As a basis for the experimental investigations, a gas fired CHP plant was selected. The design of the test rig is optimized for the operation in the laboratory, where the coolant heat is emulated by a tempering device and the exhaust heat of the CHP plant is emulated by a gas burner. With the designed test rig, it is possible to control the volume flow and the temperatures of the coolant and exhaust gas, so that different load conditions of the gas fired CHP plant can be investigated. For initial tests, the turbine in the SRC is replaced by a throttle to achieve the pressure drop of the turbine. The experimental results show, that the exhaust and coolant heat of a 36 kWel CHP plant can be emulated and the performance expectations of the cycle can be met in stable steady-state conditions. Based on the measurement results and the turbine design calculations an electric power output of the cycle of 3.8 kW will be possible, which results in a cycle efficiency of about 6.5 \% and an increase of the electrical power output of the CHP plant of about 10 \%.

In this context, perceived safety plays a critical role in their acceptance and implementation. Previous research had focused more on data security or specific digital technologies. There has also been a lack of participatory approaches to consider and empower healthcare recipients (and relatives), providers, and technology experts to broaden the phenomenon. Objective The aim of this study was to present a comprehensive perspective on the needs, influencing factors and related outcomes in the context of feeling safe with digital technologies in healthcare. Method A qualitative, exploratory, and participatory methodology was used with five guide-based focus group workshops. Each workshop explored one of five digital technology demonstrations provided at the beginning: (1) electronic health records (EHR), (2) robotics, (3) artificial intelligence (AI), (4) smart home, and (5) smart hospital. All participants were invited for a guide-based discussion. The study focused on the levels of 'involvement' and 'collaboration' by also empowering participation. The workshop target groups were actively involved in the development and execution of the workshops and were empowered. The data were analysed via a content analysis approach, with a mostly inductive procedure. Results Feeling safe was found to affect thoughts, emotions, and actions. For example, a higher level of perceived safety increased the acceptance of digital technologies, whereas a lower level of perceived safety decreased it. The corresponding needs and influencing factors differed in terms of their scope and focus depending on the context. The aspect of 'control' was most frequently addressed by all the target groups and was viewed as relevant in all the workshops. In general, digital technologies were viewed as supplements rather than substitutes for healthcare providers. Conclusion This study extends beyond the current state of research on perceived safety and the use of digital technologies in healthcare by providing a comprehensive overview of the corresponding needs and influencing factors at various levels, such as the individual, community-organizational, and system-society levels. The perceived safety of healthcare recipients and providers related to digital technologies should be taken into consideration to achieve positive implementation outcomes.}, subject = {Digitalisierung}, language = {en} } @article{MuellerBraunKeuper2025, author = {M{\"u}ller, Patrick and Braun, Alexander and Keuper, Margret}, title = {Examining the Impact of Optical Aberrations to Image Classification and Object Detection Models}, series = {IEEE Transactions on Pattern Analysis and Machine Intelligence}, journal = {IEEE Transactions on Pattern Analysis and Machine Intelligence}, publisher = {IEEE}, issn = {0162-8828}, doi = {10.1109/TPAMI.2025.3622234}, pages = {1 -- 15}, year = {2025}, language = {en} } @inproceedings{WeberThielkeFischer2019, author = {Weber, Konradin and Thielke, Jan and Fischer, Christian}, title = {Evaluation of selected physical parameters measured with smartphones}, series = {Verhandlungen der Deutschen Physikalische Gesellschaft e.V.}, booktitle = {Verhandlungen der Deutschen Physikalische Gesellschaft e.V.}, publisher = {Deutsche Physikalische Gesellschaft e.V.}, address = {Bad Honnef}, year = {2019}, subject = {Messtechnik}, language = {en} } @article{NovelliKaminskiRolletteretal.2018, author = {Novelli, Anna and Kaminski, Martin and Rolletter, Michael and Acir, Ismail-Hakki and Bohn, Birger and Dorn, Hans-Peter and Li, Xin and Lutz, Anna and Nehr, Sascha and Rohrer, Franz and Tillmann, Ralf and Wegener, Robert and Holland, Frank and Hofzumahaus, Andreas and Kiendler-Scharr, Astrid and Wahner, Andreas and Fuchs, Hendrik}, title = {Evaluation of OH and HO2 concentrations and their budgets during photooxidation of 2-methyl-3-butene-2-ol (MBO) in the atmospheric simulation chamber SAPHIR}, series = {Atmospheric Chemistry and Physics}, volume = {18}, journal = {Atmospheric Chemistry and Physics}, number = {15}, publisher = {Copernicus}, issn = {1680-7324}, doi = {10.5194/acp-18-11409-2018}, pages = {11409 -- 11422}, year = {2018}, abstract = {Several previous field studies have reported unexpectedly large concentrations of hydroxyl and hydroperoxyl radicals (OH and HO2, respectively) in forested environments that could not be explained by the traditional oxidation mechanisms that largely underestimated the observations. These environments were characterized by large concentrations of biogenic volatile organic compounds (BVOC) and low nitrogen oxide concentration. In isoprene-dominated environments, models developed to simulate atmospheric photochemistry generally underestimated the observed OH radical concentrations. In contrast, HO2 radical concentration showed large discrepancies with model simulations mainly in non-isoprene-dominated forested environments. An abundant BVOC emitted by lodgepole and ponderosa pines is 2-methyl-3-butene-2-ol (MBO), observed in large concentrations for studies where the HO2 concentration was poorly described by model simulations. In this work, the photooxidation of MBO by OH was investigated for NO concentrations lower than 200 pptv in the atmospheric simulation chamber SAPHIR at Forschungszentrum J{\"u}lich. Measurements of OH and HO2 radicals, OH reactivity (kOH), MBO, OH precursors, and organic products (acetone and formaldehyde) were used to test our current understanding of the OH-oxidation mechanisms for MBO by comparing measurements with model calculations. All the measured trace gases agreed well with the model results (within 15 \%) indicating a well understood mechanism for the MBO oxidation by OH. Therefore, the oxidation of MBO cannot contribute to reconciling the unexplained high OH and HO2 radical concentrations found in previous field studies.}, language = {en} } @article{NeefFritzenSchumacher2003, author = {Neef, Matthias and Fritzen, J.

Measuring these loads with the help of strain gauges applied to the structure becomes difficult if the mount is overdetermined and thus not every strain gauge can be assigned to a single load direction. In this study, the overdetermined mount structure of the BR715 engine was examined at one of the three mounting points between the Boeing 717 airframe and the engine, where loads in five directions were reacted. Firstly, the dependence of five measured strains upon known static load conditions at the mounting point had to be determined. For this purpose a static calibration test was carried out where defined forces and moments in known directions were applied to the structure while the output from five strain gauges was measured accordingly. The result was the desired relationship between loads and strains in terms of a matrix, which yields the corresponding load condition of the examined mounting point if multiplied with a set of strains. The same calibration procedure was carried out with a finite element model of the mount, where direct comparison to dynamic load results from the model itself was possible. With this model the validity of the above method was shown as well as possible errors which may occur while evaluating dynamic test results. The method was found to give satisfactory results even for dynamic loading, although some inertia forces disturb the signals in dynamic testing. Finally, the results from an actual dynamic engine test were processed into loads and then compared to the simulated loads from a finite element model of the engine. Good agreement was found and the indication of any remaining discrepancies was used to update the model for an even better representation of the dynamic test loads.}, language = {en} } @inproceedings{WeberKramerFischeretal.2019, author = {Weber, Konradin and Kramer, Tim and Fischer, Christian and Pohl, Tobias and B{\"o}hlke, Christoph}, title = {Evaluation of low cost and mid cost sensors for fine particulate matter at urban sites}, series = {Geophysical Research Abstracts: EGU General Assembly 2019}, volume = {21}, booktitle = {Geophysical Research Abstracts: EGU General Assembly 2019}, publisher = {Copernicus}, address = {G{\"o}ttingen}, year = {2019}, abstract = {High ambient air concentrations of fine particulate matter are a problem in many European cities, especially in traffic loaded street canyons. Therefore, the introduction of traffic restricted or traffic reduced areas is discussed as a countermeasure in several towns. However, at that point it is not always clear, in what extent the restriction of traffic in presently overloaded streets causes the exceeding of limit values in other areas of the town after the redirection of the traffic. Presently this cannot be recorded appropriately, when the concentrations of fine particulate matter are monitored only at rarely distributed single points by the official measurement systems of the environmental state agencies. On the other hand, meanwhile there are low cost and mid cost sensors for the measurement of fine particulate matter available, which enable the parallel monitoring with many measurement systems in an extended area of the town. By this way, the effect of traffic restrictions on the distribution of fine particulate matter in the city can potentially be observed. However, at this point the question arises, how reliable the results are, which are delivered by the low and mid cost sensors for fine particulate matter. For this reason different low cost and mid cost sensors have been evaluated for this study and intercompared with certified reference measurement systems for fine particulate matter. The study comprised the sensors SDS011 (Nova Fitness), which is in use already for several citizen science projects in Germany, SPS30 (Sensirion), OPC-R1 (Alphasense), OPC-N2 (Alphasense) and OPC-N3 (Alphasense). This study was performed at urban sites in D{\"u}sseldorf (Germany) for several weeks and covered different traffic loads and different meteorological situations, in order to get representative results. As atmospheric humidity can influence the measurement results, the humidity was measured in parallel to the fine particulate matter. It could be shown that the validity of the measurement results of fine particulate matter could be improved, when the parallel readings of the humidity were taken into account.}, subject = {Messtechnik}, language = {en} } @inproceedings{KerstenHaaseRiess2025, author = {Kersten, Thierry and Haase, Thomas and Riess, Bernhard M.}, title = {Evaluation of a new AI driven SoC Design Flow Approach}, series = {MPC-Workshop Januar 2024 / Januar 2025}, volume = {67/68}, booktitle = {MPC-Workshop Januar 2024 / Januar 2025}, editor = {Schmidt, Lothar}, publisher = {Technische Hochschule Ulm}, address = {Ulm}, organization = {Multi Projekt Chip Gruppe}, issn = {1868-9221}, pages = {47 -- 57}, year = {2025}, subject = {K{\"u}nstliche Intelligenz}, language = {en} } @inproceedings{HuesenvonBergSteffens2025, author = {H{\"u}sen, Jonas and von Berg, Markus and Steffens, Jochen}, title = {Evaluating the Effectiveness of Virtual Listening Tests for Balanced Armature Headphone Drivers [Abstract]}, series = {DAS|DAGA 2025: 51st Annual Meeting on Acoustics, March 17-20, 2025, Copenhagen}, booktitle = {DAS|DAGA 2025: 51st Annual Meeting on Acoustics, March 17-20, 2025, Copenhagen}, publisher = {Deutsche Gesellschaft f{\"u}r Akustik e.V.}, address = {Berlin}, year = {2025}, subject = {Kopfh{\"o}rer}, language = {en} } @inproceedings{HuesenvonBergSteffens2025, author = {H{\"u}sen, Jonsa and von Berg, Markus and Steffens, Jochen}, title = {Evaluating the Effectiveness of Virtual Listening Tests for Balanced Armature Headphone Drivers}, series = {AES International Conference on Headphone Technology 2025 August 27-29, Espoo, Finland}, booktitle = {AES International Conference on Headphone Technology 2025 August 27-29, Espoo, Finland}, number = {3}, publisher = {Audio Engineering Society}, year = {2025}, language = {en} } @inproceedings{NeefHummel2000, author = {Neef, Matthias and Hummel, Dietrich}, title = {Euler solutions for a finite-span flapping wing}, series = {"Fixed, flapping and rotary wing vehicles at very low Reynolds numbers, Notre Dame, Indiana, USA}, booktitle = {"Fixed, flapping and rotary wing vehicles at very low Reynolds numbers, Notre Dame, Indiana, USA}, year = {2000}, language = {en} } @incollection{NeefHummel2001, author = {Neef, Matthias and Hummel, Dietrich}, title = {Euler Solutions for a Finite-Span Flapping Wing}, series = {Fixed and Flapping Wing Aerodynamics for Micro Air Vehicle Applications}, volume = {16}, booktitle = {Fixed and Flapping Wing Aerodynamics for Micro Air Vehicle Applications}, editor = {Mueller, Thomas J.}, publisher = {American Institute of Aeronautics and Astronautics}, address = {Reston, VA}, isbn = {978-1-56347-517-7}, doi = {10.2514/5.9781600866654.0429.0451}, pages = {429 -- 451}, year = {2001}, language = {en} } @incollection{NeefHummel2002, author = {Neef, Matthias and Hummel, D.}, title = {Euler and Navier-Stokes Solutions for Flapping Wing Propulsion}, series = {High Performance Computing in Science and Engineering '01}, volume = {30}, booktitle = {High Performance Computing in Science and Engineering '01}, editor = {Krause, Egon and J{\"a}ger, Willi}, publisher = {Springer}, address = {Berlin}, isbn = {978-3-642-62719-4}, doi = {10.1007/978-3-642-56034-7_37}, pages = {386 -- 395}, year = {2002}, language = {en} } @article{GreilSchwarzStein2023, author = {Greil, Stefan and Schwarz, Christian and Stein, Stefan}, title = {ESG Value Creation from a Transfer Pricing Perspective}, series = {International Transfer Pricing Journal}, volume = {30}, journal = {International Transfer Pricing Journal}, number = {2}, publisher = {International Bureau of Fiscal Documentation}, issn = {2352-9172}, doi = {10.59403/csvtb1}, year = {2023}, abstract = {Achieving environmental, social and governance (ESG) targets has become one of the most important challenges for multinational enterprises (MNEs).

Given the finite computational resources of any computer system, optimization is required to ensure that the most important information is presented to the user as clearly as possible and in a timely fashion. In particular, what is desired are means whereby the perspicuity of an object may be enhanced when appropriate. An object becomes more perspicuous when the information it provides to the user becomes more readily apparent. Additionally, if a particular object provides high-priority information, it would be advantageous to make that object obtrusive as well as highly perspicuous. An object becomes more obtrusive if it draws attention to itself (or equivalently, if it is hard to ignore). This paper describes a technique whereby objects may dynamically adapt their representation in a user's environment according to a dynamic priority evaluation of the information each object provides. The three components of our approach are: - an information manager that evaluates object information priority, - an enhancement manager that tabulates rendering features associated with increasing object perspicuity and obtrusion as a function of priority, and - a resource manager that assigns available object rendering resources according to features indicated by the enhancement manager for the priority set for each object by the information manager. We consider resources like visual space (pixels), sound spatialization channels (mixels), MIDI/audio channels, and processing power, and discuss our approach applied to different applications. Assigned object rendering features are implemented locally at the object level (e.g., object facing the user using the billboard node in VRML 2.0) or globally, using helper applications (e.g., active spotlights, semi-automatic cameras).}, language = {en} } @inproceedings{IriaPreisachSlavazzaetal.2007, author = {Iria, Jose and Preisach, Christine and Slavazza, Piercarlo and Uren, Victoria and Lavelli, Alberto and Blohm, Sebastian and Dadzie, Aba-Sah and Franz, Thomas and Kompatsiaris, Ioannis and Magalhaes, Joao and Nikolopoulos, Spiros}, title = {Enhancing enterprise knowledge processes via cross-media extraction}, series = {Proceedings of the 4th international conference on Knowledge capture}, booktitle = {Proceedings of the 4th international conference on Knowledge capture}, editor = {Sleeman, Derek and Barker, Ken}, publisher = {ACM}, address = {New York, NY}, isbn = {978-1-59593-643-1}, doi = {10.1145/1298406.1298441}, pages = {175 -- 176}, year = {2007}, language = {en} } @article{BerkantOezelDurmazNurOezetal.2025, author = {Berkant {\"O}zel, Mehmet and Durmaz, Ufuk and Nur {\"O}z, Muhammed Ali and {\"U}mit Tepe, Ahmet and {\"O}z, Cemil and Uysal, {\"U}nal and Yal{\c{c}}inkaya, Orhan and Cemal Beni̇m, Ali and Alomayrah, Norah and Al-Buriahi, M.S.}, title = {Enhanced prediction of heat transfer in jet impingement cooling using an artificial intelligence: A case study}, series = {Case Studies in Thermal Engineering}, volume = {73}, journal = {Case Studies in Thermal Engineering}, publisher = {Elsevier}, issn = {2214-157X}, doi = {10.1016/j.csite.2025.106605}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-55017}, pages = {11}, year = {2025}, abstract = {This paper is about the gas turbine cooling model using the extended jet array. The aim of the present study is to explain the effect of the impinging jet configuration of elongated jet holes on the heat transfer distribution with a deep Convolutional Neural Network (CNN). CNNs preserve spatial relationships through convolutional operations—unlike traditional Artificial Neural Networks (ANNs), which require flattening of input data—allowing for higher accuracy with smaller datasets and faster training due to fewer trainable parameters. The goal is to understand how accurate and fast deep learning models with limited data can deliver predictions for complex systems such as jet impingement cooling. The proposed CNN model was compared with the numerical and experimental data. Jet impingement cooling was examined with four different Reynolds numbers (16250, 21700, 27100, 36250) and six dimensionless gaps between the jet and the target surface (G/D = 1, 2, 3, 4, 5, and 6). Mean and local Nusselt number (Nu) distributions were investigated in particular. G/D = 2 was selected as the test data for the model among the configurations. While the CFD model failed to identify this peak performance point, the CNN model accurately captured this maximum behavior despite being trained only on other configurations. Moreover, the CNN model demonstrated more suitable prediction accuracy in the first two jet impingement regions than the CFD data, especially in capturing peak Nusselt numbers and localized hot spots. It has been determined that the CNN model provided more accurate predictions of the local Nusselt numbers within the measurement region compared to the Computational Fluid Dynamics (CFD) study for the average Nu, the proposed CNN model showed a closer agreement to experimental data than numerical simulation by 4.15 \% at the Re = 32500 and G/D = 2.}, subject = {Maschinelles Lernen}, language = {en} } @article{BisigAkosaMoonetal.2016, author = {Bisig, Andr{\´e} and Akosa, Collins Ashu and Moon, Jung-Hwan and Rhensius, Jan and Moutafis, Christoforos and von Bieren, Arndt and Heidler, Jakoba and Kiliani, Gillian and Kammerer, Matthias and Curcic, Michael and Weigand, Markus and Tyliszczak, Tolek and Van Waeyenberge, Bartel and Stoll, Hermann and Sch{\"u}tz, Gisela and Lee, Kyung-Jin and Manchon, Aurelien and Kl{\"a}ui, Mathias}, title = {Enhanced Nonadiabaticity in Vortex Cores due to the Emergent Hall Effect}, series = {Physical Review Letters}, volume = {117}, journal = {Physical Review Letters}, number = {27}, publisher = {American Physical Society}, issn = {0031-9007}, doi = {10.1103/PhysRevLett.117.277203}, year = {2016}, language = {en} } @article{MandalMannaBiswasetal.2026, author = {Mandal, Dipak Kumar and Manna, Nirmal K. and Biswas, Nirmalendu and Rudra, Tansu and Kumar, Rajesh and Benim, Ali Cemal}, title = {Enhanced heat transport in magneto-nanofluidic thermal systems: adiabatic block effects in grooved channels and ANN modeling}, series = {International Journal of Thermofluids}, volume = {31}, journal = {International Journal of Thermofluids}, publisher = {Elsevier}, issn = {2666-2027}, doi = {10.1016/j.ijft.2025.101515}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-60127}, year = {2026}, abstract = {This study investigates heat transfer enhancement in magneto-nanofluidic systems through the strategic placement of adiabatic blocks in grooved channels. Using CuO-H2O nanofluid in a bottom-heated channel with circular expansion, we examine the complex interactions between forced convection, magnetic fields, and uoyancy effects. Through systematic numerical analysis, we explore the combined influences of Rayleigh, Reynolds, and Hartmann numbers on thermal performance. Our findings reveal significant heat transfer enhancement (up to 137 \%) under optimal conditions, particularly with vertical magnetic field orientation at Re = 100 and Ha = 30. The results demonstrate how adiabatic blocks modify flow structures, with larger blocks diminishing vortex intensity while elevated Ra generates secondary vortices that interact with primary circulations. Magnetic field effects show notable dependence on orientation, with vertical fields generally promoting better heat transfer than horizontal configurations. To complement the numerical analysis, we develop a predictive model using Artificial Neural Network (ANN) for Nusselt numbers across various operating conditions, achieving over 99 \% accuracy.

In this article, we review the entire untargeted metabolomics workflow from the perspective of information visualization, visual analytics and visual data integration. Data visualization is a crucial step at every stage of the metabolomics workflow, where it provides core components of data inspection, evaluation, and sharing capabilities. However, due to the large number of available data analysis tools and corresponding visualization components, it is hard for both users and developers to get an overview of what is already available and which tools are suitable for their analysis. In addition, there is little cross-pollination between the fields of data visualization and metabolomics, leaving visual tools to be designed in a secondary and mostly ad hoc fashion. With this review, we aim to bridge the gap between the fields of untargeted metabolomics and data visualization. First, we introduce data visualization to the untargeted metabolomics field as a topic worthy of its own dedicated research, and provide a primer on cutting-edge visualization research into data visualization for both researchers as well as developers active in metabolomics. We extend this primer with a discussion of best practices for data visualization as they have emerged from data visualization studies. Second, we provide a practical roadmap to the visual tool landscape and its use within the untargeted metabolomics field. Here, for several computational analysis stages within the untargeted metabolomics workflow, we provide an overview of commonly used visual strategies with practical examples. In this context, we will also outline promising areas for further research and development.

The interaction of growing microtubules with steric objects is known to slow down microtubule growth and accelerate catastrophes. We show that the lifetime distributions of stalled microtubules, as well as the corresponding lifetime distributions of freely growing microtubules, can be fully described with a simple phenomenological 1D model based on noisy microtubule growth and a single EB3-dependent hydrolysis rate. This same model is furthermore capable of explaining both the previously reported mild catastrophe dependence on microtubule growth rates and the catastrophe statistics during tubulin washout experiments.}, subject = {Mikrotubulus}, language = {en} } @phdthesis{Ackermann2024, author = {Ackermann, David}, title = {Dynamic Sound Sources for Virtual Acoustic Reality: Description, Implementation and Evaluation}, publisher = {TU Berlin}, address = {Berlin}, doi = {10.14279/depositonce-19949}, school = {Hochschule D{\"u}sseldorf}, year = {2024}, abstract = {terns, especially those presented by natural sources such as musical instruments or human voices, is crucial. While static sound sources, such as loudspeakers, have a relatively consistent acoustic footprint, dynamic sources present a multi-faceted set of challenges. Musical instruments, for example, have dynamic radiation patterns. The directivity of these instruments changes not only with frequency, but also with the specific note being played, and with the performer's gestures. These dynamic effects of directivity influences both the perceived loudness and the timbre at a given location within the audience and shapes the spatial characteristics of the sound field produced. This modulation is crucial when recreating authentic acoustic environments, whether in a virtual environment or in real-world architectural designs. Essentially, for an acoustic simulation to be considered accurate, it must capture these nuances. The intricate interplay of directivity, pitch and motion significantly shapes the listening experience and requires deeper integration of these elements into future simulations and designs.}, subject = {Musikalische Akustik}, language = {en} } @inproceedings{TiatorBuentigGeiger2018, author = {Tiator, Marcel and B{\"u}ntig, Fabian and Geiger, Christian}, title = {Dynamic Movement Monitoring - Algorithms for Real Time Exercise Movement Feedback}, series = {Proceedings of the 4th International Conference on Information and Communication Technologies for Ageing Well and e-Health, Funchal, 22.03.2018 - 23.03.2018}, booktitle = {Proceedings of the 4th International Conference on Information and Communication Technologies for Ageing Well and e-Health, Funchal, 22.03.2018 - 23.03.2018}, publisher = {SCITEPRESS - Science and Technology Publications}, isbn = {978-989-758-299-8}, doi = {10.5220/0006735001840191}, pages = {184 -- 191}, year = {2018}, language = {en} } @incollection{NiemannWestkaemper2006, author = {Niemann, J{\"o}rg and Westk{\"a}mper, Engelbert}, title = {Dynamic life cycle performance simulation of production systems}, series = {Innovation in Life Cycle Engineering and Sustainable Development}, booktitle = {Innovation in Life Cycle Engineering and Sustainable Development}, editor = {Brissaud, Daniel and Tichkiewitch, Serge and Zwolinski, Peggy}, publisher = {Springer Netherlands}, address = {Dordrecht}, isbn = {978-1-4020-4601-8}, doi = {10.1007/1-4020-4617-0_29}, pages = {419 -- 428}, year = {2006}, language = {en} } @article{ReimsTophoven2021, author = {Reims, Nancy and Tophoven, Silke}, title = {Double Burden of Disability and Poverty: Does Vocational Rehabilitation Ease the School-to-Work Transition?}, series = {Social Inclusion}, volume = {9}, journal = {Social Inclusion}, number = {4}, publisher = {Cogitatio}, issn = {2183-2803}, doi = {10.17645/si.v9i4.4649}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-40131}, pages = {92 -- 102}, year = {2021}, abstract = {Poor young people more often face health difficulties, (learning) disabilities, and are overrepresented in special schools. Consequently, youth from poor households disproportionately frequently participate in disability-specific programs aiming to improve their educational levels and labor market opportunities. They face a double burden of disability and poverty. In our study, we look at poor and non-poor youth with disabilities (YPWD) who participate in vocational rehabilitation (VR) and whether VR helps them (a) in transitioning into employment and (b) in leaving poverty. We examine the association between the receipt of initial basic income support (BIS) as a poverty indicator, later labor market outcomes, and earned vocational qualification using administrative data. We make use of a sample of all persons accepted for VR in 2010 (N = 36,645). We employ logit models on VR attendees' labor market outcomes three and five years after being accepted for VR as well as on their earned vocational qualifications. Beside initial poverty status, we control for educational level, type, and degree of disability and program pattern during the VR process. Our findings show that YPWD from poor households have a decreased likelihood of a vocational certificate and employment. Additionally, they are more likely to receive BIS than young people not from poor households and thus more likely to remain poor. In conclusion, VR seems to support poor YPWD less in their school-to-work transitions. Thus, disability-specific programs should be more tailored to the social situations of participants, and counsellors should be more sensitive to their social backgrounds.}, language = {en} } @book{OPUS4-5154, title = {Doppelvilla am Juras{\"u}dfuß}, volume = {Band 3}, publisher = {Braun Publishing}, address = {Berlin}, organization = {Architektenkammer Berlin}, isbn = {978-3-03768-152-7}, pages = {30 -- 31}, year = {2014}, language = {en} } @article{HautmannSteinHanischetal.2009, author = {Hautmann, Christopher and Stein, Petra and Hanisch, Charlotte and Eichelberger, Ilka and Pl{\"u}ck, Julia and Walter, Daniel and D{\"o}pfner, Manfred}, title = {Does parent management training for children with externalizing problem behavior in routine care result in clinically significant changes?}, series = {Psychotherapy research : journal of the Society for Psychotherapy Research}, volume = {19}, journal = {Psychotherapy research : journal of the Society for Psychotherapy Research}, number = {2}, publisher = {Taylor \& Francis}, doi = {10.1080/10503300902777148}, pages = {224 -- 233}, year = {2009}, language = {en} } @inproceedings{vonBergHimmelinSteffens2024, author = {von Berg, Markus and Himmelin, Hendrik and Steffens, Jochen}, title = {Does Noise Sensitivity Decrease Auditory Task Performance and Person-Reliability?

The origins of noise sensitivity are mostly unclear, but it has a higher prevalence among people with attention deficit hyperactivity disorder and autism, and could be caused by increased neural excitation due to sound, resulting in increased cognitive load. In this case, noise sensitivity can be expected to decrease people's mental performance in both auditory and non-auditory tasks. The former was tested in an experiment using a dual-task paradigm where participants had to solve a visual task in the presence of environmental sounds and afterwards had to recall which sounds they perceived and to evaluate the overall soundscape pleasantness and loudness. Preliminary results indicate that participants' noise sensitivity is positively correlated with the experienced cognitive load as well as with loudness and unpleasantness judgments. Also, noise sensitivity was negatively associated with the performance in the recall task and the test-retest-reliability of their judgments. These findings support the idea that noise sensitivity is a consequence of difficulties in filtering irrelevant auditory information.}, language = {en} } @article{VocksKosfelderWuchereretal.2008, author = {Vocks, Silja and Kosfelder, Joachim and Wucherer, Maike and W{\"a}chter, Alexandra}, title = {Does habitual body avoidance and checking behavior influence the decrease of negative emotions during body exposure in eating disorders?}, series = {Psychotherapy research}, volume = {18}, journal = {Psychotherapy research}, number = {4}, publisher = {Taylor \& Francis}, doi = {10.1080/10503300701797008}, pages = {412 -- 419}, year = {2008}, language = {en} } @techreport{FranzScherpStaab2008, author = {Franz, Thomas and Scherp, Ansgar and Staab, Steffen}, title = {Does a Semantic Desktop Facilitate Your Daily Tasks?}, series = {Arbeitsberichte aus dem Bereich Informatik}, journal = {Arbeitsberichte aus dem Bereich Informatik}, publisher = {Universit{\"a}t Koblenz-Landau}, address = {Koblenz}, organization = {Universit{\"a}t Koblenz-Landau}, issn = {1864-0850}, url = {http://nbn-resolving.de/urn:nbn:de:kola-2564}, year = {2008}, language = {en} } @incollection{VoigtUnterfraunerStelzer2017, author = {Voigt, Christian and Unterfrauner, Elisabeth and Stelzer, Roland}, title = {Diversity in FabLabs: Culture, Role Models and the Gendering of Making}, series = {Internet Science}, volume = {Lecture Notes in Computer Science, 10673}, booktitle = {Internet Science}, editor = {Kompatsiaris, Ioannis and Cave, Jonathan and Satsiou, Anna and Carle, Georg and Passani, Antonella and Kontopoulos, Efstratios and Diplaris, Sotiris and McMillan, Donald}, publisher = {Springer International Publishing}, address = {Cham}, isbn = {978-3-319-70283-4}, doi = {10.1007/978-3-319-70284-1_5}, pages = {52 -- 68}, year = {2017}, language = {en} } @article{Langmann2010, author = {Langmann, Reinhard}, title = {Distributed Web-Based Control System}, series = {International Journal of Online Engineering (iJOE)}, volume = {6}, journal = {International Journal of Online Engineering (iJOE)}, number = {3}, publisher = {iJOE}, doi = {10.3991/ijoe.v6i3.1345}, year = {2010}, language = {en} } @unpublished{YuwonoSchwungSchwung2024, author = {Yuwono, Steve and Schwung, Dorothea and Schwung, Andreas}, title = {Distributed Stackelberg Strategies in State-based Potential Games for Autonomous Decentralized Learning Manufacturing Systems}, publisher = {arXiv}, doi = {10.48550/arXiv.2408.06397}, pages = {14}, year = {2024}, abstract = {This article describes a novel game structure for autonomously optimizing decentralized manufacturing systems with multi-objective optimization challenges, namely Distributed Stackelberg Strategies in State-Based Potential Games (DS2-SbPG). DS2-SbPG integrates potential games and Stackelberg games, which improves the cooperative trade-off capabilities of potential games and the multi-objective optimization handling by Stackelberg games. Notably, all training procedures remain conducted in a fully distributed manner. DS2-SbPG offers a promising solution to finding optimal trade-offs between objectives by eliminating the complexities of setting up combined objective optimization functions for individual players in self- learning domains, particularly in real-world industrial settings with diverse and numerous objectives between the sub-systems. We further prove that DS2-SbPG constitutes a dynamic potential game that results in corresponding converge guarantees. Experimental validation conducted on a laboratory-scale testbed highlights the efficacy of DS2-SbPG and its two variants, such as DS2-SbPG for single-leader-follower and Stack DS2-SbPG for multi-leader-follower. The results show significant reductions in power consumption and improvements in overall performance, which signals the potential of DS2-SbPG in real-world applications.}, subject = {Maschinelles Lernen}, language = {en} } @inproceedings{RyskeldievOchiaiCohenetal.2018, author = {Ryskeldiev, Bektur and Ochiai, Yoichi and Cohen, Michael and Herder, Jens}, title = {Distributed Metaverse: Creating Decentralized Blockchain-based Model for Peer-to-peer Sharing of Virtual Spaces for Mixed Reality Applications}, series = {Proceedings of the 9th Augmented Human International Conference}, booktitle = {Proceedings of the 9th Augmented Human International Conference}, publisher = {ACM}, isbn = {978-1-4503-5415-8}, doi = {10.1145/3174910.3174952}, pages = {7 -- 9}, year = {2018}, abstract = {Mixed reality telepresence is becoming an increasingly popular form of interaction in social and collaborative applications.
