For this, they are typically immobilized on mica substrates by adding millimolar concentrations of Mg2+ ions to the sample solution, which enable the adsorption of the negatively charged DONs at the like-charged mica surface. These non-physiological Mg2+ concentrations, however, present a serious limitation in such experiments as they may interfere with the reactions and processes under investigation. Therefore, we here evaluate three approaches to efficiently immobilize DONs at mica surfaces under essentially Mg2+-free conditions. These approaches rely on the pre-adsorption of different multivalent cations, i.e., Ni2+, poly-l-lysine (PLL), and spermidine (Spdn). DON adsorption is studied in phosphate-buffered saline (PBS) and pure water. In general, Ni2+ shows the worst performance with heavily deformed DONs. For 2D DON triangles, adsorption at PLL- and in particular Spdn-modified mica may outperform even Mg2+-mediated adsorption in terms of surface coverage, depending on the employed solution. For 3D six-helix bundles, less pronounced differences between the individual strategies are observed. Our results provide some general guidance for the immobilization of DONs at mica surfaces under Mg2+-free conditions and may aid future in situ AFM studies.</jats:p>"}],"status":"public","_id":"23023","user_id":"48864","department":[{"_id":"302"}],"language":[{"iso":"eng"}]},{"type":"journal_article","publication":"ESAFORM 2021","abstract":[{"lang":"eng","text":"<jats:p>Three-dimensional modelling enables to determine the in-plane material flow in asymmetrical situation.

The material separation in the die-sided joining partner, which in two-dimensional simulation is often described by macro- and micromechanical fracture criteria, was realised in this study based on a defined contact condition. By means of a shear-cutting simulation, a correlation between the break angle and the separation stress was determined, which was used as a separation criterion in the shear-clinching simulation. The separation line was confirmed using post-particles. To validate this model, the results of the simulation using a quadratic single-point specimen were compared to the experiments with respect to the distortion of the joining partner.

Furthermore, for vehicle-to-grid applications, bidirectional converters with transformers are generally more complex and have a higher count on semiconductor switches than transformerless solutions. However, when using non-isolated DC-DC converters within an OBC, the large common-mode (CM) capacitance comprising capacitive parasitics of the traction battery as well as explicit Y-capacitors connecting the high-voltage DC-system (HV-system) within specific HV-loads to ground has to be considered. For the PFC front-end stage, when supplied from the three-phase mains this means that generation of high-frequency and high-amplitude CM voltages, as it is common e.g. with the conventional six-switch full-bridge converter, has to be strictly avoided. For this reason, a modified topology is suggested leading to a different mode of operation and to a very low common-mode noise behaviour: The three-phase four-wire full-bridge PFC with split DC-link, whose midpoint is connected to the mains neutral provides very stable potentials at the DC-link rails and therefore it can be classified as Zero-CM-topology.For dedicated single-phase operation, as required for most OBC, an additional balancing leg may be added to the topology to reduce the required DC-link capacitance and allow non-electrolytic capacitors.The function of the bidirectional Zero-CM three-phase four-wire full-bridge PFC was verified by simulation and on an 11 kW-laboratory sample. The power factor is above 0.999 and an efficiency of 98 % is measured.","lang":"eng"}],"status":"public","_id":"29849","user_id":"66","department":[{"_id":"52"}],"keyword":["Three-phase four-wire","OBC","Y2G","PFC","CM","EY charger","balancing circuit"],"language":[{"iso":"eng"}]},{"title":"Transferring Online Reinforcement Learning for Electric Motor Control From Simulation to Real-World Experiments","doi":"10.1109/ojpel.2021.3065877","date_updated":"2022-02-22T08:51:05Z","date_created":"2021-05-12T16:54:27Z","author":[{"full_name":"Book, Gerrit","last_name":"Book","first_name":"Gerrit"},{"last_name":"Traue","full_name":"Traue, Arne","first_name":"Arne"},{"full_name":"Balakrishna, Praneeth","last_name":"Balakrishna","first_name":"Praneeth"},{"first_name":"Anian","last_name":"Brosch","orcid":"0000-0003-4871-1664","full_name":"Brosch, Anian","id":"75779"},{"first_name":"Maximilian","id":"52638","full_name":"Schenke, Maximilian","orcid":"0000-0001-5427-9527","last_name":"Schenke"},{"last_name":"Hanke","full_name":"Hanke, Sören","id":"25027","first_name":"Sören"},{"first_name":"Wilhelm","orcid":"0000-0001-9490-1843","last_name":"Kirchgässner","full_name":"Kirchgässner, Wilhelm","id":"49265"},{"last_name":"Wallscheid","orcid":"https://orcid.org/0000-0001-9362-8777","full_name":"Wallscheid, Oliver","id":"11291","first_name":"Oliver"}],"year":"2021","page":"187-201","citation":{"chicago":"Book, Gerrit, Arne Traue, Praneeth Balakrishna, Anian Brosch, Maximilian Schenke, Sören Hanke, Wilhelm Kirchgässner, and Oliver Wallscheid. “Transferring Online Reinforcement Learning for Electric Motor Control From Simulation to Real-World Experiments.” <i>IEEE Open Journal of Power Electronics</i>, 2021, 187–201. <a href=\"https://doi.org/10.1109/ojpel.2021.3065877\">https://doi.org/10.1109/ojpel.2021.3065877</a>.","ieee":"G.

The generally weak reverse\r\nrecovery behaviour of the intrinsic body diodes of those\r\nMOSFETs causes significant turn-on losses when being forced\r\nto hard commutations. Continuous operation in this way will\r\nlead to self-destruction of the transistors. Consequently,\r\nzero-voltage switching (ZVS) is essential in a MOSFET-based\r\ninverter stage. To ensure ZVS, the LLC converter is operated in\r\nthe inductive region. On the contrary, IGBTs show dominant\r\nturn-off losses and are therefore conventionally not applied in\r\nLLC converters typically requiring high switching frequencies\r\nto achieve low output voltages. However, if the LLC converter\r\nis intentionally designed for capacitive operation, zero-current\r\nswitching (ZCS) is enabled and thus robust and cost-efficient\r\nIGBTs can be applied in the inverter stage. The aim of this work\r\nis to investigate the use IGBTs in the inverter of an LLC\r\nconverter. The theory behind the capacitive operated LLC is\r\nderived using a switched simulation model and compared with\r\nthe fundamental harmonic approximation (FHA). The results\r\nprove FHA to be useless for practical converter design. Instead,\r\na stress value analysis based on switched model simulations is\r\nproposed to the design a capacitive operated LLC utilizing ZCS.\r\nA 2 kW prototype for on-board EV applications was built to\r\nverify the theory and design approach. The prototype confirms\r\nthe derived theory and thus the deployment of IGBTs in the\r\ninverter stage of LLC resonant converters. Synchronous\r\nrectification turns out to require a specific control solution, but\r\nif given the resulting efficiency in the most critical operation\r\npoint exceeds the value of a MOSFET-based (inductive\r\noperated) LLC-design of an identical application. Therefore,\r\nthis concept should be further developed."}],"status":"public","publication":"2021 IEEE Applied Power Electronics Conference and Exposition (APEC)","type":"conference","ddc":["620"],"language":[{"iso":"eng"}],"_id":"29871","department":[{"_id":"52"}],"user_id":"60223"},{"type":"journal_article","publication":"Journal of Open Source Software","status":"public","_id":"21254","user_id":"11291","department":[{"_id":"52"}],"article_number":"2498","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["2475-9066"]},"year":"2021","citation":{"bibtex":"@article{Balakrishna_Book_Kirchgässner_Schenke_Traue_Wallscheid_2021, title={gym-electric-motor (GEM): A Python toolbox for the simulation of electric drive systems}, DOI={<a href=\"https://doi.org/10.21105/joss.02498\">10.21105/joss.02498</a>}, number={2498}, journal={Journal of Open Source Software}, author={Balakrishna, Praneeth and Book, Gerrit and Kirchgässner, Wilhelm and Schenke, Maximilian and Traue, Arne and Wallscheid, Oliver}, year={2021} }","mla":"Balakrishna, Praneeth, et al. “Gym-Electric-Motor (GEM): A Python Toolbox for the Simulation of Electric Drive Systems.” <i>Journal of Open Source Software</i>, 2498, 2021, doi:<a href=\"https://doi.org/10.21105/joss.02498\">10.21105/joss.02498</a>.","short":"P.

These in turn affect the property profile of the joint. For example, it is possible to use different tools to flexibly adapt clinching points to the respective required load regime. Clinching points dimensioned in this way can be geometrically similar, but have different mechanical stress states, which leads to different properties in terms of load-bearing behavior. Within the scope of this work, the clinching process with different tools in optimal and compromise design and its effect on the force and form-closure component, is investigated in a torsion test of the clinched connection. Clinched steel sheets with two thicknesses and joining directions are analyzed. Virtual experiments are carried out using finite element analyses (FEA) of the joining process and are followed by a springback simulation. Subsequently, the surface pressure between the two joining partners in the clinching points is calculated on the basis of the results from the FEA and the transmittable moment of the connection, as an indicator for the force-closure component, is determined. Finally, the experimental and simulated data are compared and discussed.","lang":"eng"}],"publication":"IOP Conference Series: Materials Science and Engineering","type":"journal_article","doi":"10.1088/1757-899x/1157/1/012003","title":"Numerical and experimental investigation of the transmission moment of clinching points","volume":1157,"date_created":"2022-03-28T12:43:52Z","author":[{"first_name":"C.","last_name":"Steinfelder","full_name":"Steinfelder, C."},{"first_name":"J.","full_name":"Kalich, J.","last_name":"Kalich"},{"last_name":"Brosius","full_name":"Brosius, A.","first_name":"A."},{"full_name":"Füssel, U.","last_name":"Füssel","first_name":"U."}],"date_updated":"2022-03-29T15:38:11Z","intvolume":"      1157","page":"012003","citation":{"chicago":"Steinfelder, C., J.

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.</jats:p>\r\n              </jats:sec><jats:sec>\r\n                <jats:title>Results</jats:title>\r\n                <jats:p>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).</jats:p>\r\n              </jats:sec><jats:sec>\r\n                <jats:title>Conclusion</jats:title>\r\n                <jats:p>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.

Therefore, mechanical joining technologies like clinching are in the focus of current research activities. For multi-material joints of metals and thermoplastic composites thermally assisted clinching processes with advanced tool concepts are well developed. The material-specific properties of fibre-reinforced thermoplastics have a significant influence on the joining process and the resulting material structure in the joining zone. For this reason, it is important to investigate these influences in detail and to understand the phenomena occurring during the joining process. Additionally, this provides the basis for a validation of a numerical simulation of such joining processes. In this paper, the material structure in a joint resulting from a thermally assisted clinching process is investigated. The joining partners are an aluminium sheet and a thermoplastic composite (organo sheet). Using computed tomography enables a three-dimensional investigation that allows a detailed analysis of the phenomena in different joining stages and in the material structure of the finished joint. Consequently, this study provides a more detailed understanding of the material behavior of thermoplastic composites during thermally assisted clinching.</jats:p>"}],"type":"journal_article","publication":"Production Engineering","language":[{"iso":"eng"}],"user_id":"36235","department":[{"_id":"157"}],"_id":"28568","citation":{"chicago":"Gröger, Benjamin, Daniel Köhler, Julian Vorderbrüggen, Juliane Troschitz, Robert Kupfer, Gerson Meschut, and Maik Gude. “Computed Tomography Investigation of the Material Structure in Clinch Joints in Aluminium Fibre-Reinforced Thermoplastic Sheets.” <i>Production Engineering</i>, 2021. <a href=\"https://doi.org/10.1007/s11740-021-01091-x\">https://doi.org/10.1007/s11740-021-01091-x</a>.","ieee":"B.

However, their role in virtual prototyping and the correlation to later steps in the design process need further investigation. We introduce a metric for RISC-V instruction and register coverage for binary software. The metric measures if RISC-V instruction types are executed and if GPRs, CSRs, and FPRs are accessed. The analysis is applied by the means of a virtual prototype which is based on an abstract instruction and register model with direct correspondence to their bit level representation. In this context, we analyzed three different openly available test suites: the RISC-V architectural testing framework, the RISC-V unit tests, and programs which are automatically generated by the RISC-V Torture test generator. We discuss their tradeoffs and show that by combining them to a unified test suite we can arrive at a 100% GPR and FPR register coverage and a 98.7% instruction type coverage.","lang":"eng"}],"status":"public","_id":"32125","user_id":"5603","department":[{"_id":"58"}],"language":[{"iso":"eng"}]},{"type":"conference","status":"public","department":[{"_id":"152"},{"_id":"321"}],"user_id":"60633","_id":"24439","language":[{"iso":"eng"}],"page":"37-41","corporate_editor":["ETI - The European Technology Institute"],"citation":{"chicago":"Gräßler, Iris, and Philipp Hesse. “Decision Support for Product Specific Recycling.” edited by ETI - The European Technology Institute, 37–41.

Der Ablauf der Analyse gliedert sich in mehrere Schritte: Zunächst wird für das zu simulierende Binärprogramm eine WCET-Analyse mit aiT durchgeführt. Im Preprocessing des aiT-Reports wird daraufhin ein WCET-annotierter Kontrollflussgraph erzeugt. Dabei entsprechen die Knoten im Kontrollflussgraph den aiT-Blöcken und die Kanten dem jeweiligen Worst-Case-Zeitverbrauch, um das Programm im aktuellen Ausführungskontext vom Quell- bis zum Zielblock laufen zu lassen. Nach dem Preprocessing werden Binärprogramm und der zuvor erzeugte, zeitannotierte Kontrollflussgraph von QEMU geladen und gemeinsam simuliert.\r\n\r\nDie Implementierung des QTA basiert auf der Standard TGI Plugin API (Tiny Code Generator Plugin API), die seit Ende 2019 mit QEMU V4.2 verfügbar ist.

The charge sampling technique is mathematically analyzed in detail and compared to conventional switched-capacitor sampling. The mathematical analysis allows to predict the sampler bandwidth as well as the degradation of sampling precision due to analog circuit impairments such as integrator gain error, integration capacitor leakage, hold-mode droop, thermal noise, and clock jitter. Furthermore, design, simulation, and measurement results of an ultra-broadband charge sampler IC in SiGe BiCMOS technology are presented. The charge sampler IC achieves a 1dB bandwidth of 70 GHz. A resolution of better than 5.9 effective number of bits (ENOB) is measured from 0 to 70 GHz at a sampling rate of 5 GS/s. The results suggest that charge sampling using an IHC is a viable concept for ultra-broadband sampling.","lang":"eng"}],"publication":"IEEE Transactions on Circuits and Systems I: Regular Papers","keyword":["Electrical and Electronic Engineering"],"language":[{"iso":"eng"}]},{"doi":"10.1016/j.numecd.2021.11.011","date_updated":"2022-08-18T10:41:47Z","volume":32,"author":[{"first_name":"Helena","last_name":"Ludwig-Walz","full_name":"Ludwig-Walz, Helena"},{"last_name":"Nyasordzi","full_name":"Nyasordzi, Juliana","first_name":"Juliana"},{"full_name":"Weber, Katharina S.","last_name":"Weber","first_name":"Katharina S."},{"first_name":"Anette","full_name":"Buyken, Anette","id":"65985","last_name":"Buyken"},{"first_name":"Anja","full_name":"Kroke, Anja","last_name":"Kroke"}],"intvolume":"        32","page":"833-852","citation":{"chicago":"Ludwig-Walz, Helena, Juliana Nyasordzi, Katharina S.

One of these methods is based on transmission measurements of cylindrical polymeric specimens. Here, the experimental setup consists of two transducers, which excite and receive the waveguide modes at the faces of the cylinder. The measurement, as well as a forward model, are used to determine material parameters of the polymeric specimen in an inverse approach.\r\n1-3 piezoelectric composites are used as an active element because they can be approximated by a thickness vibration only. This allows an easy identification of Mason model parameters to characterise the transducers’ vibration behaviour. \r\nHowever, sensitivity analysis shows a high uncertainty in the determination of the mechanical shear parameters due to the uniform excitation. To increase the sensitivity to these shear motions, arbitrary excitations were investigated by means of numerical simulation. \r\nIn order to be able to realise the determined optimal excitation, new transducer prototypes were designed. By subdividing the electrodes of the active element, for example, ring-shaped excitation is feasible. Furthermore, it can be shown that modelling these transducers with a one-dimensional Mason model is sufficient."}],"file":[{"file_size":906618,"file_id":"25268","file_name":"daga","access_level":"closed","date_updated":"2021-10-04T07:49:28Z","creator":"dmitrij","date_created":"2021-10-04T07:49:28Z","success":1,"relation":"main_file","content_type":"application/octet-stream"}],"publication":"Fortschritte der Akustik - DAGA 2021","ddc":["620"],"language":[{"iso":"eng"}],"place":"Wien","citation":{"ieee":"D.
