@unpublished{30866, abstract = {{Automated machine learning (AutoML) strives for the automatic configuration of machine learning algorithms and their composition into an overall (software) solution - a machine learning pipeline - tailored to the learning task (dataset) at hand. Over the last decade, AutoML has developed into an independent research field with hundreds of contributions. While AutoML offers many prospects, it is also known to be quite resource-intensive, which is one of its major points of criticism. The primary cause for a high resource consumption is that many approaches rely on the (costly) evaluation of many machine learning pipelines while searching for good candidates. This problem is amplified in the context of research on AutoML methods, due to large scale experiments conducted with many datasets and approaches, each of them being run with several repetitions to rule out random effects. In the spirit of recent work on Green AI, this paper is written in an attempt to raise the awareness of AutoML researchers for the problem and to elaborate on possible remedies. To this end, we identify four categories of actions the community may take towards more sustainable research on AutoML, i.e. Green AutoML: design of AutoML systems, benchmarking, transparency and research incentives.}}, author = {{Tornede, Tanja and Tornede, Alexander and Hanselle, Jonas Manuel and Wever, Marcel Dominik and Mohr, Felix and Hüllermeier, Eyke}}, booktitle = {{arXiv:2111.05850}}, title = {{{Towards Green Automated Machine Learning: Status Quo and Future Directions}}}, year = {{2021}}, } @article{30864, author = {{Schulz, Andreas and Wecker, Christian and Inguva, Venkatesh and Lopatin, Alexey S. and Kenig, Eugeny Y.}}, issn = {{0009-2509}}, journal = {{Chemical Engineering Science}}, keywords = {{Applied Mathematics, Industrial and Manufacturing Engineering, General Chemical Engineering, General Chemistry}}, publisher = {{Elsevier BV}}, title = {{{A PLIC-based method for species mass transfer at free fluid interfaces}}}, doi = {{10.1016/j.ces.2021.117357}}, volume = {{251}}, year = {{2021}}, } @phdthesis{27284, author = {{Wever, Marcel Dominik}}, title = {{{Automated Machine Learning for Multi-Label Classification}}}, doi = {{10.17619/UNIPB/1-1302}}, year = {{2021}}, } @article{30906, abstract = {{Abstract Background Hand amputation can have a truly debilitating impact on the life of the affected person. A multifunctional myoelectric prosthesis controlled using pattern classification can be used to restore some of the lost motor abilities. However, learning to control an advanced prosthesis can be a challenging task, but virtual and augmented reality (AR) provide means to create an engaging and motivating training. Methods In this study, we present a novel training framework that integrates virtual elements within a real scene (AR) while allowing the view from the first-person perspective. The framework was evaluated in 13 able-bodied subjects and a limb-deficient person divided into intervention (IG) and control (CG) groups. The IG received training by performing simulated clothespin task and both groups conducted a pre- and posttest with a real prosthesis. When training with the AR, the subjects received visual feedback on the generated grasping force. The main outcome measure was the number of pins that were successfully transferred within 20 min (task duration), while the number of dropped and broken pins were also registered. The participants were asked to score the difficulty of the real task (posttest), fun-factor and motivation, as well as the utility of the feedback. Results The performance (median/interquartile range) consistently increased during the training sessions (4/3 to 22/4). While the results were similar for the two groups in the pretest, the performance improved in the posttest only in IG. In addition, the subjects in IG transferred significantly more pins (28/10.5 versus 14.5/11), and dropped (1/2.5 versus 3.5/2) and broke (5/3.8 versus 14.5/9) significantly fewer pins in the posttest compared to CG. The participants in IG assigned (mean ± std) significantly lower scores to the difficulty compared to CG (5.2 ± 1.9 versus 7.1 ± 0.9), and they highly rated the fun factor (8.7 ± 1.3) and usefulness of feedback (8.5 ± 1.7). Conclusion The results demonstrated that the proposed AR system allows for the transfer of skills from the simulated to the real task while providing a positive user experience. The present study demonstrates the effectiveness and flexibility of the proposed AR framework. Importantly, the developed system is open source and available for download and further development. }}, author = {{Boschmann, Alexander and Neuhaus, Dorothee and Vogt, Sarah and Kaltschmidt, Christian and Platzner, Marco and Dosen, Strahinja}}, issn = {{1743-0003}}, journal = {{Journal of NeuroEngineering and Rehabilitation}}, keywords = {{Health Informatics, Rehabilitation}}, number = {{1}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Immersive augmented reality system for the training of pattern classification control with a myoelectric prosthesis}}}, doi = {{10.1186/s12984-021-00822-6}}, volume = {{18}}, year = {{2021}}, } @article{30907, author = {{Rodriguez, Alfonso and Otero, Andres and Platzner, Marco and De la Torre, Eduardo}}, issn = {{0018-9340}}, journal = {{IEEE Transactions on Computers}}, keywords = {{Computational Theory and Mathematics, Hardware and Architecture, Theoretical Computer Science, Software}}, pages = {{1--1}}, publisher = {{Institute of Electrical and Electronics Engineers (IEEE)}}, title = {{{Exploiting Hardware-Based Data-Parallel and Multithreading Models for Smart Edge Computing in Reconfigurable FPGAs}}}, doi = {{10.1109/tc.2021.3107196}}, year = {{2021}}, } @article{30924, abstract = {{Wood fiber reinforcement of plastics is almost limited to polypropylene, polyethylene, polyvinyl chloride and polystyrene. Wood fiber reinforcement of thermoplastic polyurethanes (TPU) is a new research field and paltry studied scientifically. Wood fiber reinforcement can carry out synergistic effects between sustainability, material or product price reduction, improved mechanical properties at high elongation, and brilliant appearance and haptics. In order to evaluate to what extent the improvement of mechanical properties depend on material-specific parameters (fiber type, fiber content) and on process-specific parameters (holding pressure, temperature control and injection speed), differently filled compounds were injection molded according to a partial factorial test plan and subjected to characterizing test procedures (tensile test, Shore hardness and notched impact test). Tensile strength showed significant dependence on barrel temperature, fiber type and interaction between holding pressure and barrel temperature in the region of interest. Young’s modulus can be influenced by fiber content but not by fiber type. Notched impact strength showed a significant influence of cylinder temperature, fiber content, fiber type and the interaction between cylinder temperature and fiber content in the region of interest. Shore hardness is related to fiber content and the interaction between mold temperature and injection flow rate. Our results show not only that wood-filled TPU can be processed very well by injection molding, but also that the mechanical properties depend significantly on temperature control in the injection-molding process. Moreover, considering the significant reinforcing effect of the wood fibers, a good fiber-matrix adhesion can be assumed.}}, author = {{Moritzer, Elmar and Richters, Maximilian}}, issn = {{2504-477X}}, journal = {{Journal of Composites Science}}, keywords = {{Engineering (miscellaneous), Ceramics and Composites}}, number = {{12}}, publisher = {{MDPI AG}}, title = {{{Injection Molding of Wood-Filled Thermoplastic Polyurethane}}}, doi = {{10.3390/jcs5120316}}, volume = {{5}}, year = {{2021}}, } @article{23944, author = {{Moritzer, Elmar and Richters, Maximilian}}, journal = {{Journal of Applied Polymer Science}}, publisher = {{Wiley }}, title = {{{Characterization of wood-filled thermoplastic polyurethane for the injection modling process}}}, year = {{2021}}, } @article{23948, author = {{Moritzer, Elmar and Richters, Maximilian and Hillemeyer, Johannes and Krassmann, Dimitri}}, journal = {{Joining Plastics}}, title = {{{Mit dem Schraubblind-Durchsetznieten Metallteile mit Composites bei einseitiger Zugänglichkeit verbinden}}}, year = {{2021}}, } @article{23886, author = {{Kastein, Mara and Finke, Josefine and Horwath, Ilona}}, issn = {{2196-3886}}, journal = {{Voluntaris}}, pages = {{135--151}}, title = {{{Florian braucht Mehmet mehr als umgekehrt: Herausforderungen und Potenziale für Inklusion in der Freiwilligen Feuerwehr}}}, doi = {{10.5771/2196-3886-2021-1-135}}, year = {{2021}}, } @misc{24446, booktitle = {{Erscheinungsformen, Erklärungsversuche und Gegenstrategien, GENDER }}, editor = {{Kastein, Mara and Horwath, Ilona and Finke, Josefine and Duglar Sezer, Nilgün}}, pages = {{92--107}}, title = {{{Ohne den ‚Weissen Mann‘ würden Leute wie Sie noch in Erdhöhlen wohnen.“ - Die Markierung der Unmarkierten}}}, doi = {{doi.org/10.3224/84742528.01}}, year = {{2021}}, } @inbook{24477, author = {{Horwath, Ilona and Kastein, Mara and Duglar Sezer, Nilgün}}, booktitle = {{Feuerwehren im Spiegel gesellschaftlicher Diversität}}, editor = {{Duglar Sezer, Nilgün and Horwath, Ilona and Kastein, Mara}}, title = {{{Feuerwehren im Spiegel gesellschaftlicher Diversität}}}, year = {{2021}}, } @article{24172, abstract = {{In dem Artikel werden die Metaphern gleichstellungsorientierter Männerpolitik als eine Form diskursiver Praktiken untersucht.

The components are produced by depositing fine, molten plastic droplets. The main advantage of the APF is the open-parameter control of the associated machine system. Thus, the process parameters can be optimized for individual applications. A special and new application of the APF is the production of interconnecting porous structures. As this is a novel approach with this manufacturing process, the general producibility and reproducibility must first be proven. Therefore, the relevant process parameters with an influence on the open-pored structures are identified. The volume of the individual plastic droplets, the distance between the droplets and the layer thickness are the three decisive influencing factors. With the use of analysis methods, the free spaces created in the structure are described by a uniformly constructed, interconnected pore structure. This means that the pores are interconnected in three dimensions. Reproducibility is evaluated by repeated production and thru the changed conditions during the manufacturing process. In addition, the multiplication and a change of geometry are evaluated in such a way that there is no influence on the pore size. Irregularities when depositing the first layer are caused by unevenness of the building platform. A suitable test arrangement is set up to determine the liquid permeability. A characteristic value is determined to describe the permeability to liquids.}}, author = {{Moritzer, Elmar and Hirsch, André and Dalmer, C.}}, isbn = {{978-3-030-54333-4}}, pages = {{112--129}}, publisher = {{Springer}}, title = {{{Investigation of Plastic Freeformed, Open-Pored Structures with Regard to Producibility, Reproducibility and Liquid Permeability}}}, doi = {{10.1007/978-3-030-54334-1}}, year = {{2021}}, } @article{24162, author = {{Moritzer, Elmar and Wächter, Julian and Elsner, Christian Lennart}}, journal = {{Macromolecular Symposia}}, number = {{1}}, publisher = {{Wiley}}, title = {{{Investigation of Specific FDM Process Parameters to Optimize the Polymer Discharge of Carbon Fiber Reinforced PEEK}}}, doi = {{10.1002/masy.202000269}}, volume = {{395}}, year = {{2021}}, } @article{24681, author = {{Moritzer, Elmar and Schumacher, Christian}}, issn = {{1022-1360}}, journal = {{Macromolecular Symposia}}, number = {{1}}, title = {{{Stainless Steel Parts Produced by Fused Deposition Modeling and a Sintering Process Compared to Components Manufactured in Selective Laser Melting}}}, doi = {{10.1002/masy.202000275}}, volume = {{395}}, year = {{2021}}, } @article{21810, author = {{Otroshi, Mortaza and Meschut, Gerson and Bielak, Christian Roman and Masendorf, Lukas and Esderts, Alfons}}, issn = {{1662-9795}}, journal = {{Key Engineering Materials}}, pages = {{35--40}}, publisher = {{Trans Tech Publications Ltd}}, title = {{{Modeling of Stiffness Anisotropy in Simulation of Self-Piercing Riveted Components}}}, doi = {{https://doi.org/10.4028/www.scientific.net/KEM.883.35}}, volume = {{883}}, year = {{2021}}, } @inproceedings{24554, author = {{Moritzer, Elmar and Elsner, Christian Lennart and Wächter, Julian and Knoop, Frederick}}, booktitle = {{79th Annual Technical Conference of the Society of Plastics Engineers (ANTEC)}}, title = {{{Investigation and Realization of Watertight FDM Structures Made of Ultem 9085 in Pressurized Systems}}}, year = {{2021}}, }
