Therefore, experimental material characterization processes are conducted to determine the material properties of sheet metal and generate flow curves. In this regard, there are a number of procedures which are accompanied by varying experimental efforts. This paper presents various methods of determining flow curves for HCT590X as well as EN AW-6014, including varying specimen geometries and diverse hardening laws for extrapolation procedures. The flow curves thus generated are compared considering the variety of plastic strains occurring in mechanical joining processes. The material data generated are implemented in simulation models for the joining technologies, clinching and self-piercing riveting. The influence of the varied methods on the predictive accuracy of the simulation model is analysed. The evaluation of the differing flow curves is achieved by comparing the geometric formation of the joints and the required joining forces of the processes with experimentally investigated joints.}}, author = {{Böhnke, Max and Kappe, Fabian and Bobbert, Mathias and Meschut, Gerson}}, issn = {{2195-8572}}, journal = {{Materials Testing}}, number = {{6}}, pages = {{493--500}}, publisher = {{De Gruyter}}, title = {{{Influence of various procedures for the determination of flow curves on the predictive accuracy of numerical simulations for mechanical joining processes}}}, doi = {{10.1515/mt-2020-0082}}, volume = {{63}}, year = {{2021}}, } @article{34226, abstract = {{The increasing use of multi-material constructions lead to a continuous increase in the use of mechanical joining techniques due to the wide range of joining possibilities as well as the high load-bearing capacities of the joints.

Although policies, such as the energy labelling, prompted technical improvements and decreased appliance energy consumption throughout recent decades, important parameters were disregarded. These refer to the efficiency loss over time and the consumer behaviour. The objective of this contribution was to develop a dynamic energy model to determine the power consumption of refrigeration appliances considering degradation factors and behaviour. These were included by model parameters for direct consumer interactions, such as the storage behaviour, door openings and temperature setting, as well as indirect actions, e.g. exposing an appliance to specific temperature conditions at an installation site. For this, an online-survey was conducted to evaluate the consumer behaviour. A total of 706 consumers participated in the national questionnaire, serving as input for the dynamic energy model. It was found that the efficiency loss increases the power consumption by at least 1% annually, leading to an excess of 10% after 10 years of usage. Another important finding was that 32.5% of appliance’s power consumption results from consumer behaviour, whereas the promotion of behavioural changes leads to a significant decrease of the consumer-induced consumption. Consequently, this study provides a tool to evaluate the impact of policies targeting refrigeration appliances, stressing that efficiency loss and behaviour should be integrated into future policy approaches.}}, author = {{Hueppe, Christian and Geppert, Jasmin and Moenninghoff-Juessen, Julia and Wolff, Lena and Stamminger, Rainer and Paul, Andreas and Elsner, Andreas and Vrabec, Jadran and Wagner, Hendrik and Hoelscher, Heike and Becker, Wolfgang and Gries, Ulrich and Freiberger, Alfred}}, issn = {{0301-4215}}, journal = {{Energy Policy}}, title = {{{Investigating the real life energy consumption of refrigeration appliances in Germany: Are present policies sufficient?}}}, doi = {{10.1016/j.enpol.2021.112275}}, year = {{2021}}, } @inproceedings{44222, author = {{Jende, Yvonne Kristin}}, booktitle = {{The Place of Memory and the Memory of Place, International Conference}}, location = {{London}}, publisher = {{London Centre of Interdisciplinary Research}}, title = {{{Crossraods of Collective Memory.

In these considerations, the actual purpose of research is of particular importance. Here, the research aims at improving the traffic flow by controlling the Traffic Light Systems (TLS) of the examined area which is why the current traffic state and the route choices of individual road users are the matter of interest. An integer optimization problem is derived to fit the current simulation to the latest field measurements. The concept can be transferred to any road traffic network and results in an observation of the current multimodal traffic state matching at the given sensor position. First case studies show promosing results in terms of deviations between reality and simulation.}}, author = {{Malena, Kevin and Link, Christopher and Mertin, Sven and Gausemeier, Sandra and Trächtler, Ansgar}}, booktitle = {{VEHITS 2021 Proceedings of the 7th International Conference on Vehicle Technology and Intelligent Transport Systems}}, isbn = {{978-989-758-513-5}}, keywords = {{Microscopic Traffic Simulation, Online State Estimation, Mixed Road Users, Sensor Fusion, Integer Programming, Route Choice, Vehicle2Infrastructure}}, location = {{Online Streaming}}, pages = {{386--395}}, publisher = {{SCITEPRESS}}, title = {{{Online State Estimation for Microscopic Traffic Simulations using Multiple Data Sources*}}}, volume = {{7}}, year = {{2021}}, } @misc{44234, author = {{Berger, Thilo Frederik}}, title = {{{Combining Mobility, Heterogeneity, and Leasing Approaches for Online Resource Allocation}}}, year = {{2021}}, } @misc{44233, author = {{Pranger, Sebastian}}, title = {{{Online k-Facility Reallocation using k-Server Algorithms}}}, year = {{2021}}, } @article{41508, author = {{Camberg, Alan Adam and Andreiev, Anatolii and Pramanik, Sudipta and Hoyer, Kay-Peter and Tröster, Thomas and Schaper, Mirko}}, issn = {{0921-5093}}, journal = {{Materials Science and Engineering: A}}, keywords = {{Mechanical Engineering, Mechanics of Materials, Condensed Matter Physics, General Materials Science}}, publisher = {{Elsevier BV}}, title = {{{Strength enhancement of AlMg sheet metal parts by rapid heating and subsequent cold die stamping of severely cold-rolled blanks}}}, doi = {{10.1016/j.msea.2021.142312}}, volume = {{831}}, year = {{2021}}, } @inproceedings{44256, author = {{Behler, Felix and Ines, Böker}}, booktitle = {{Sommerschule 21: Aktuelle Perspektiven der Deutsch-Türkischen und Interkulturellen Germanistik im Rahmen der Germanistischen Institutspartnerschaft 'Pader-EgeBosporus'.
