Controlling an unsteady fluid flow is particularly important, as flow control is a key enabler for technologies in energy (e.g., wind, tidal, and combustion), transportation (e.g., planes, trains, and automobiles), security (e.g., tracking airborne contamination), and health (e.g., artificial hearts and artificial respiration). However, the high-dimensional, nonlinear, and multi-scale dynamics make real-time feedback control infeasible. Fortunately, these high- dimensional systems exhibit dominant, low-dimensional patterns of activity that can be exploited for effective control in the sense that knowledge of the entire state of a system is not required. Advances in machine learning have the potential to revolutionize flow control given its ability to extract principled, low-rank feature spaces characterizing such complex systems.We present a novel deep learning modelpredictive control framework that exploits low-rank features of the flow in order to achieve considerable improvements to control performance. Instead of predicting the entire fluid state, we use a recurrent neural network (RNN) to accurately predict the control relevant quantities of the system, which are then embedded into an MPC framework to construct a feedback loop. In order to lower the data requirements and to improve the prediction accuracy and thus the control performance, incoming sensor data are used to update the RNN online. The results are validated using varying fluid flow examples of increasing complexity.","lang":"eng"}],"publication":"Theoretical and Computational Fluid Dynamics","doi":"10.1007/s00162-020-00520-4","main_file_link":[{"open_access":"1","url":"https://link.springer.com/content/pdf/10.1007/s00162-020-00520-4.pdf"}],"oa":"1","date_updated":"2022-01-06T06:52:48Z","volume":34,"author":[{"full_name":"Bieker, Katharina","id":"32829","last_name":"Bieker","first_name":"Katharina"},{"last_name":"Peitz","orcid":"https://orcid.org/0000-0002-3389-793X","id":"47427","full_name":"Peitz, Sebastian","first_name":"Sebastian"},{"full_name":"Brunton, Steven L.","last_name":"Brunton","first_name":"Steven L."},{"first_name":"J.

In order to preserve the relatively low data requirements for an\r\napproximation via Dynamic Mode Decomposition, a quantization approach was\r\nrecently proposed in [Peitz & Klus, Automatica 106, 2019]. This way, control\r\nof nonlinear dynamical systems can be realized by means of switched systems\r\ntechniques, using only a finite set of autonomous Koopman operator-based\r\nreduced models. These individual systems can be approximated very efficiently\r\nfrom data. The main idea is to transform a control system into a set of\r\nautonomous systems for which the optimal switching sequence has to be computed.\r\nIn this article, we extend these results to continuous control inputs using\r\nrelaxation. This way, we combine the advantages of the data efficiency of\r\napproximating a finite set of autonomous systems with continuous controls. We\r\nshow that when using the Koopman generator, this relaxation --- realized by\r\nlinear interpolation between two operators --- does not introduce any error for\r\ncontrol affine systems. This allows us to control high-dimensional nonlinear\r\nsystems using bilinear, low-dimensional surrogate models. The efficiency of the\r\nproposed approach is demonstrated using several examples with increasing\r\ncomplexity, from the Duffing oscillator to the chaotic fluidic pinball."}],"status":"public","type":"journal_article","publication":"SIAM Journal on Applied Dynamical Systems","language":[{"iso":"eng"}],"_id":"16309","user_id":"47427","department":[{"_id":"101"}],"year":"2020","citation":{"short":"S.

We find that under the current mechanism over 74% of students act strategically by misrepresenting at least one of their preferences. Nevertheless, not all students are able to improve their outcome by doing so. We show that this is mainly due to the incomplete information of students and naiveté.

To\r\nhandle the increasing number of devices and the resulting traffic,\r\na flexible and scalable factory network is necessary which can be\r\nrealized using softwarization technologies like Network Function\r\nVirtualization (NFV). However, the security risks increase with\r\nthe increasing number of new devices, so that cyber security must\r\nalso be considered in NFV-based networks.\r\n\r\nTherefore, extending our previous work, we showcase threat\r\ndetection using a cloud-native NFV-driven intrusion detection\r\nsystem (IDS) that is integrated in our industrial-specific network\r\nservices. As a result of the threat detection, the affected network\r\nservice is put into quarantine via automatic network reconfiguration.\r\nWe use the 5GTANGO service platform to deploy our\r\ndeveloped network services on Kubernetes and to initiate the\r\nnetwork reconfiguration.","lang":"eng"}],"publication":"IEEE Conference on Network Softwarization (NetSoft) Demo Track","type":"conference","language":[{"iso":"eng"}],"department":[{"_id":"75"}],"user_id":"35343","_id":"16400","project":[{"grant_number":"761493","name":"5G Development and validation platform for global industry-specific network services and Apps","_id":"28"},{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C4","_id":"16"}]},{"date_updated":"2022-01-06T06:51:45Z","author":[{"first_name":"Simon","last_name":"Pukrop","id":"44428","full_name":"Pukrop, Simon"},{"first_name":"Alexander","id":"13536","full_name":"Mäcker, Alexander","last_name":"Mäcker"},{"first_name":"Friedhelm","id":"15523","full_name":"Meyer auf der Heide, Friedhelm","last_name":"Meyer auf der Heide"}],"date_created":"2019-10-15T12:19:49Z","title":"Approximating Weighted Completion Time for Order Scheduling with Setup Times","year":"2020","citation":{"short":"S.

In this paper, a pulsed YVO4 Laser source with a wavelength of 1064 nm and a maximum power of 25 W was utilized to increase the surface area of the steel HCT490X in order to improve its bonding properties with a carbon fibre reinforced polymer (CFRP). Investigated was the influence of the scanning speed of the laser source on the bonding properties. For this purpose, the steel surfaces were ablated at a scanning speed between 1500 and 4500 mm/s. Afterwards the components were bonded with the adhesive HexBond™ 677. After lap shear tests were carried out on the specimen, the surfaces were inspected using scanning electron microscopy (SEM). The experiments revealed that the bonding quality can be improved with a high scanning speed, even when the surface is not completely ablated.</jats:p>"}],"status":"public","publication":"Production Engineering","type":"journal_article","language":[{"iso":"eng"}],"_id":"24563","department":[{"_id":"158"}],"user_id":"43822"},{"status":"public","type":"conference","publication":"29th Annual International Solid Freeform Fabrication Symposium","extern":"1","language":[{"iso":"ger"}],"user_id":"40263","_id":"27106","citation":{"apa":"Kummert, C.,  Diekmann, W., Tews, K., &#38; Schmid, H.-J.
