@article{24541, abstract = {{The mechanical properties of joined structures are determined considerably by the chosen joining technology. With the aim of providing a method that enables a faster and more profound decision-making in the spatial distribution of joining points during product development, a new method for the load path analysis of joining points is presented. For an exemplary car body, the load type in the joining elements, i.e. pure tensile, shear and combined tensile-shear loads, is determined using finite element analysis (FEA). Based on the evaluated loads, the resulting load paths in selected joining points are analyzed using a 2D FE-model of a clinching point. State of the art methods for load path analysis are dependent on the selected coordinate system or the existing stress state. Thus, a general statement about the load transmission path is not possible at this time. Here, a novel method for the analysis of load paths is used, which is independent of the alignment of the analyzed geometry. The basic assumption of the new load path analysis method was confirmed by using a simple specimen with a square hole in different orientations. The results presented here show a possibility to display the load transmission path invariantly. In further steps, the method will be extended for 3D analysis and the investigation of more complex assemblies. The primary goal of this methodical approach is an even load distribution over the joining elements and the component. This will provide a basis for future design approaches aimed at reducing the number of joining elements in joined structures.}}, author = {{Steinfelder, Christian and Martin, Sven and Brosius, Alexander and Tröster, Thomas}}, issn = {{1662-9795}}, journal = {{Key Engineering Materials}}, pages = {{73--80}}, title = {{{Load Path Transmission in Joining Elements}}}, doi = {{10.4028/www.scientific.net/kem.883.73}}, year = {{2021}}, } @article{24548, author = {{Martin, Sven and Tröster, Thomas}}, journal = {{ESAFORM 2021}}, title = {{{Joint point loadings in car bodies – the influence of manufacturing tolerances and scatter in material properties}}}, doi = {{10.25518/esaform21.3801}}, year = {{2021}}, } @inproceedings{26994, author = {{Stallmeister, Tim and Martin, Sven and Marten, Thorsten and Tröster, Thomas}}, location = {{Bad Nauheim}}, title = {{{Experimental investigation on lightweight potentials of fiber-metal-laminates for automotive battery cases}}}, year = {{2021}}, } @inproceedings{23835, author = {{Dörner, Marius and Schöppner, Volker}}, booktitle = {{ANTEC 21}}, title = {{{Development of an Analytical Mathematical Modelling Approach for a More Precise Description of Disperse Melting in Solid Bed Breaking Screw Concepts}}}, year = {{2021}}, } @article{31769, author = {{Moritzer, Elmar and Richters, Maximilian}}, issn = {{2504-477X}}, journal = {{ Journal of Composites Science}}, number = {{12}}, title = {{{Injection Molding of Wood-Filled Thermoplastic Polyurethane}}}, year = {{2021}}, } @article{31757, author = {{Moritzer, Elmar and Krassmann, Dimitri}}, journal = {{Welding in the World}}, title = {{{Development of a new joining technology for hybrid joints of sheet metal and continuous fiber-reinforced thermoplastics}}}, year = {{2021}}, } @inproceedings{30297, author = {{Rozo Vasquez, Julian and Arian, Bahman and Riepold, Markus and Walther, Frank and Homberg, Werner and Trächtler, Ansgar}}, booktitle = {{Proceedings of the 11th International Work­shop NDT in Progress}}, location = {{Prague}}, title = {{{Magnetic Barkhausen noise analysis for microstructural effects separation during flow forming of metastable austenite 304L.}}}, year = {{2021}}, } @inproceedings{23465, abstract = {{One of the main objectives of production engineering is to reproducibly manufacture (complex) defect-free parts.

Closed-loop process control represents a promising approach for a solution in this context. The state of the art involves using this approach to control geometric parameters such as a length. So far, no research or applications have been conducted with closed-loop control for microstructure and product properties.

For early education, increasingly, the setting of a kindergarten is targeted. However, when cHRI and research are brought into a kindergarten, a range of ethical and related procedural aspects have to be considered and dealt with. While ethical models elaborated within other human–robot interaction settings, e.g., assisted living contexts, can provide some important indicators for relevant issues, we argue that it is important to start developing a systematic approach to identify and tackle those ethical issues which rise with cHRI in kindergarten settings on a more global level and address the impact of the technology from a macroperspective beyond the effects on the individual. Based on our experience in conducting studies with children in general and pedagogical considerations on the role of the institution of kindergarten in specific, in this paper, we enfold some relevant aspects that have barely been addressed in an explicit way in current cHRI research. Four areas are analyzed and key ethical issues are identified in each area: (1) the institutional setting of a kindergarten, (2) children as a vulnerable group, (3) the caregivers’ role, and (4) pedagogical concepts. With our considerations, we aim at (i) broadening the methodology of the current studies within the area of cHRI, (ii) revalidate it based on our comprehensive empirical experience with research in kindergarten settings, both laboratory and real-world contexts, and (iii) provide a framework for the development of a more systematic approach to address the ethical issues in cHRI research within kindergarten settings.}}, author = {{Tolksdorf, Nils Frederik and Siebert, Scarlet and Zorn, Isabel and Horwath, Ilona and Rohlfing, Katharina J.}}, issn = {{1875-4791}}, journal = {{International Journal of Social Robotics}}, pages = {{129--140}}, title = {{{Ethical Considerations of Applying Robots in Kindergarten Settings: Towards an Approach from a Macroperspective}}}, doi = {{10.1007/s12369-020-00622-3}}, year = {{2021}}, } @article{44375, author = {{Chormey, Dotse Selali and Tonbul, Güldeniz and Soylu, Güneş and Saygılar, Ahmet and Bakırdere, Sezgin}}, issn = {{0003-2719}}, journal = {{Analytical Letters}}, keywords = {{Dispersive liquid-liquid microextraction (DLLME), gas chromatography – mass spectrometry (GC-MS), polycyclic aromatic hydrocarbons, QuEChERS}}, number = {{2}}, pages = {{237--245}}, publisher = {{Informa UK Limited}}, title = {{{Determination of Four Priority Polycyclic Aromatic Hydrocarbons in Food Samples by Gas Chromatography – Mass Spectrometry (GC-MS) after Vortex Assisted Dispersive Liquid-Liquid Microextraction (DLLME)}}}, doi = {{10.1080/00032719.2021.1922432}}, volume = {{55}}, year = {{2021}}, } @misc{44386, author = {{Ahrens, Stephan}}, booktitle = {{In: Filmblatt 25:73/74 }}, pages = {{142--145}}, title = {{{Hermann Kappelhoff, Christine Lötscher, Daniel Illger (Hg.): Filmische Seitenblicke.

The approach is divided into five steps, which includes the extension of the SysML meta model. This allows the optimization of skill-based human-machine interaction.

The Trojan is detached from inputs/outputs during place-and-route and re-connected only when the FPGA is being programmed, thus activating the Trojan circuit without any need for a trigger logic.
