Für verschiedene physikalische Eigenschaften, Betriebsbedingungen und Materialklassen werden daher geeignete messtechnische Verfahren zur Materialcharakterisierung benötigt. In der vorliegenden Arbeit wird ein Verfahren zur ultraschallbasierten Charakterisierung der mechanischen Eigenschaften von homogenen und faserverstärkten thermoplastischen Polymeren unter Berücksichtigung der Richtungsabhängigkeit vorgestellt. Plattenförmige Probekörper werden dazu mittels Laser-Pulsen hoher Energie breitbandig angeregt und die resultierenden akustischen Lamb-Wellen aufgezeichnet. Auf Basis der dispersiven Eigenschaften der detektierten Wellenleitermoden werden in einem inversen Verfahren die Parameter eines linear-elastischen Materialmodells identifiziert. Darüber hinaus wird ein Verfahren zur vollständigen Charakterisierung der Richtungsabhängigkeit in orthotropen Materialien wie Faserverbundwerkstoffen unter Verwendung eines zweidimensionalen Simulationsmodells vorgestellt. Das Messverfahren wird anhand einer Untersuchungsreihe an künstlich gealterten Polymer- und Faserverbundwerkstoffen verifiziert und die Übertragbarkeit der Ergebnisse auf den quasistatischen Fall betrachtet. Im Vergleich mit den Ergebnissen mechanischer Zugversuche werden die Voraussetzungen und Einschränkungen, insbesondere durch die Annahme eines ideal-elastischen Materialmodells, diskutiert."},{"lang":"eng","text":"Precise knowledge of material properties is a great concern in the design of technical systems, and in the monitoring of such systems during operation. Therefore, metrological processes are required for materials characterisation with respect to specific physical properties, operational conditions and classes of materials. In the work presented herein, a measurement procedure for the ultrasonic characterization of mechanical properties of homogeneous and fiber-reinforced thermoplastic polymer materials is presented, considering the different degrees of anisotropy. For this, acoustic Lamb waves are excited in a plate-shaped specimen using high-energy laser pulses, and then recorded.Based on the dispersive characteristics of the detected waveguide modes, an inverse procedure is applied to identify the parameters of a linear-elastic material model. Further, a procedure for completely characterising the orthotropy of materials like fiber-reinforced composites using a two-dimensional simulation model is presented. The measurement procedure is verified by examining artificially aged homogeneous polymers and composites, also considering the applicability of results to the quasistatic case. Comparing to the results of corresponding mechanical tensile tests, preconditions and limitations of the procedure are discussed, specifically regarding the assumption of an ideal-elastic material model."}],"citation":{"chicago":"Webersen, Manuel. <i>Zerstörungsfreie Charakterisierung der elastischen Materialeigenschaften thermoplastischer Polymerwerkstoffe mittels Ultraschall</i>.

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

Remarquably, this algorithm exploits the fact that during its execution, many collisions of robots occur. Such collisions are interpreted as a success because it is assumed that such collided robots behave the same from now on. This is acceptable under the assumption that each robot is represented by a single point. Otherwise, collisions should be avoided. In this paper, we consider a continuous Go-To-The-Center algorithm in which the robots continuously observe the positions of their neighbors and adapt their speed (assuming a speed limit) and direction. Our first results are time bounds of O(n2) for gathering in two dimensions Euclidean space, and Θ(n) for the one dimension. Our main contribution is the introduction and evaluation of a continuous algorithm which performs Go-To-The-Center considering only the neighbors of a robot with respect to the Gabriel subgraph of the visibility graph, i.e. Go-To-The-Gabriel-Center algorithm. We show that this modification still correctly executes gathering in one and two dimensions, with the same time bounds as above. Simulations exhibit a severe difference of the behavior of the Go-To-The-Center and the Go-To-The-Gabriel-Center algorithms: Whereas lots of collisions occur during a run of the Go-To-The-Center algorithm, typically only one, namely the final collision occurs during a run of the Go-To-The-Gabriel-Center algorithm. We can prove this “collisionless property” of the Go-To-The-Gabriel-Center algorithm for one dimension. In two-dimensional Euclidean space, we conjecture that the “collisionless property” holds for almost every initial configuration. We support our conjecture with measurements obtained from the simulation where robots execute both continuous Go-To-The-Center and Go-To-The-Gabriel-Center algorithms.\r\n","lang":"eng"}],"publication":"Theoretical Computer Science","department":[{"_id":"63"}],"keyword":["Local algorithms","Distributed algorithms","Collisionless gathering","Mobile robots","Multiagent system"],"type":"journal_article","date_created":"2021-06-28T09:34:45Z","status":"public","volume":852,"user_id":"15415","_id":"22511","page":"29-40","citation":{"ama":"Li S, Meyer auf der Heide F, Podlipyan P.

Although DOX has been widely studied, the existing literature of DOX-loaded DNA-carriers remains limited and incoherent. Here, based on an in-depth spectroscopic analysis, we characterize and optimize the DOX loading into different 2D and 3D scaffolded DNA origami nanostructures (DONs). In our experimental conditions, all DONs show similar DOX binding capacities (one DOX molecule per two to three base pairs), and the binding equilibrium is reached within seconds, remarkably faster than previously acknowledged. To characterize drug release profiles, DON degradation and DOX release from the complexes upon DNase I digestion was studied. For the employed DONs, the relative doses (DOX molecules released per unit time) may vary by two orders of magnitude depending on the DON superstructure. In addition, we identify DOX aggregation mechanisms and spectral changes linked to pH, magnesium, and DOX concentration. These features have been largely ignored in experimenting with DNA nanostructures, but are probably the major sources of the incoherence of the experimental results so far. Therefore, we believe this work can act as a guide to tailoring the release profiles and developing better drug delivery systems based on DNA-carriers.</jats:p>","lang":"eng"}],"publication":"Nucleic Acids Research","citation":{"ama":"Ijäs H, Shen B, Heuer-Jungemann A, et al.

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.

Thus, the distortion of the sheets to be joined can be characterized more exactly. This study shows a method for building up a three-dimensional shear-clinching framework without damage criteria. In fact, the die-sided sheet in shear-clinching was designed as a pre-punched sheet and slugs. 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. In general, the built three-dimensional framework provides for further tool developments with regard to the reduction of distortion in shear-clinching.</jats:p>","lang":"eng"}],"language":[{"iso":"eng"}],"_id":"21679","user_id":"36544","doi":"10.25518/esaform21.1948","title":"A method for three-dimensional modelling of the shear-clinching process","status":"public","year":"2021","author":[{"full_name":"Han, Daxin","first_name":"Daxin","last_name":"Han","id":"36544"},{"full_name":"Yang, Chen","first_name":"Chen","last_name":"Yang"},{"id":"32056","full_name":"Meschut, Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246","first_name":"Gerson"}],"publication_status":"published","date_updated":"2022-01-06T06:55:10Z"},{"project":[{"name":"Vermiedene Kreuzungen von Lamb-Wellenmoden in mehrlagigen Strukturen","_id":"105","grant_number":"449607253"}],"citation":{"mla":"Zeipert, Henning, et al. <i>Measurement and Simulation of Lamb Waves in Adhesive-Bonded Multilayer Systems</i>. 2021, pp. 91–92, doi:<a href=\"https://doi.org/10.5162/SMSI2021/A8.2\">10.5162/SMSI2021/A8.2</a>.","bibtex":"@inproceedings{Zeipert_Claes_Johannesmann_Webersen_Lugovtsova_Prager_Henning_2021, title={Measurement and Simulation of Lamb Waves in Adhesive-bonded Multilayer Systems}, DOI={<a href=\"https://doi.org/10.5162/SMSI2021/A8.2\">10.5162/SMSI2021/A8.2</a>}, author={Zeipert, Henning and Claes, Leander and Johannesmann, Sarah and Webersen, Manuel and Lugovtsova, Yevgeniya and Prager, Jens and Henning, Bernd}, year={2021}, pages={91–92} }","ama":"Zeipert H, Claes L, Johannesmann S, et al.

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."}],"date_created":"2022-02-15T09:14:56Z","type":"conference","keyword":["Three-phase four-wire","OBC","Y2G","PFC","CM","EY charger","balancing circuit"],"department":[{"_id":"52"}],"status":"public","year":"2021","title":"Common-Mode-Free Bidirectional Three-Phase PFC-Rectifier for Non-Isolated EV Charger","author":[{"full_name":"Strothmann, Benjamin","last_name":"Strothmann","first_name":"Benjamin","id":"22556"},{"id":"71291","full_name":"Schafmeister, Frank","first_name":"Frank","last_name":"Schafmeister"},{"id":"66","last_name":"Böcker","orcid":"0000-0002-8480-7295","first_name":"Joachim","full_name":"Böcker, Joachim"}],"date_updated":"2022-02-21T19:25:17Z","publication_status":"published","_id":"29849","publisher":"IEEE","language":[{"iso":"eng"}],"doi":"10.1109/apec42165.2021.9487462","user_id":"66"},{"user_id":"66","doi":"10.1109/ojpel.2021.3065877","_id":"22162","language":[{"iso":"eng"}],"page":"187-201","publication_status":"published","date_updated":"2022-02-22T08:51:05Z","author":[{"last_name":"Book","first_name":"Gerrit","full_name":"Book, Gerrit"},{"full_name":"Traue, Arne","last_name":"Traue","first_name":"Arne"},{"full_name":"Balakrishna, Praneeth","first_name":"Praneeth","last_name":"Balakrishna"},{"id":"75779","last_name":"Brosch","orcid":"0000-0003-4871-1664","first_name":"Anian","full_name":"Brosch, Anian"},{"id":"52638","full_name":"Schenke, Maximilian","orcid":"0000-0001-5427-9527","last_name":"Schenke","first_name":"Maximilian"},{"id":"25027","full_name":"Hanke, Sören","last_name":"Hanke","first_name":"Sören"},{"id":"49265","last_name":"Kirchgässner","first_name":"Wilhelm","orcid":"0000-0001-9490-1843","full_name":"Kirchgässner, Wilhelm"},{"id":"11291","last_name":"Wallscheid","first_name":"Oliver","orcid":"https://orcid.org/0000-0001-9362-8777","full_name":"Wallscheid, Oliver"}],"publication_identifier":{"issn":["2644-1314"]},"year":"2021","title":"Transferring Online Reinforcement Learning for Electric Motor Control From Simulation to Real-World Experiments","status":"public","department":[{"_id":"52"}],"type":"journal_article","date_created":"2021-05-12T16:54:27Z","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>.","short":"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.

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"}],"project":[{"name":"TRR 285: TRR 285","_id":"130","grant_number":"418701707"},{"name":"TRR 285 - B: TRR 285 - Project Area B","_id":"132"},{"_id":"131","name":"TRR 285 - A: TRR 285 - Project Area A"},{"name":"TRR 285 – A04: TRR 285 - Subproject A04","_id":"138"},{"_id":"140","name":"TRR 285 – B01: TRR 285 - Subproject B01"}],"date_created":"2022-03-28T12:43:52Z","type":"journal_article","year":"2021","title":"Numerical and experimental investigation of the transmission moment of clinching points","status":"public","author":[{"first_name":"C.","last_name":"Steinfelder","full_name":"Steinfelder, C."},{"first_name":"J.","last_name":"Kalich","full_name":"Kalich, J."},{"first_name":"A.","last_name":"Brosius","full_name":"Brosius, A."},{"first_name":"U.","last_name":"Füssel","full_name":"Füssel, U."}],"date_updated":"2022-03-29T15:38:11Z","intvolume":"      1157","page":"012003","_id":"30648","language":[{"iso":"eng"}],"user_id":"68518","doi":"10.1088/1757-899x/1157/1/012003","volume":1157},{"doi":"10.1186/s12984-021-00822-6","article_number":"25","language":[{"iso":"eng"}],"date_updated":"2022-04-18T10:04:16Z","publication_status":"published","intvolume":"        18","year":"2021","title":"Immersive augmented reality system for the training of pattern classification control with a myoelectric prosthesis","author":[{"full_name":"Boschmann, Alexander","first_name":"Alexander","last_name":"Boschmann"},{"last_name":"Neuhaus","first_name":"Dorothee","full_name":"Neuhaus, Dorothee"},{"full_name":"Vogt, Sarah","last_name":"Vogt","first_name":"Sarah"},{"first_name":"Christian","last_name":"Kaltschmidt","full_name":"Kaltschmidt, Christian"},{"id":"398","first_name":"Marco","last_name":"Platzner","full_name":"Platzner, Marco"},{"full_name":"Dosen, Strahinja","last_name":"Dosen","first_name":"Strahinja"}],"publication_identifier":{"issn":["1743-0003"]},"keyword":["Health Informatics","Rehabilitation"],"type":"journal_article","department":[{"_id":"78"}],"date_created":"2022-04-18T10:02:20Z","abstract":[{"text":"<jats:title>Abstract</jats:title><jats:sec>\r\n                <jats:title>Background</jats:title>\r\n                <jats:p>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.

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.

To describe the damage behavior of the material in the process chain simulations, it is important to calibrate the parameters of damage model more accurately.
