Additionally, in bioelectrochemical systems (BES), cell appendages have been shown to participate in extracellular electron transfer. In this work, the cell appendix formation of Clostridium acetobutylicum in biofilms of a BES are imaged and compared with conventional biofilms. Under all observed conditions, the cells possess filamentous appendages with a higher number and density in the BES. Differences in the amount of extracellular polymeric substance in the biofilms of the electrodes lead to the conclusion that the cathode can be used as electron donor and the anode as electron acceptor by C. acetobutylicum. When using conductive atomic force microscopy, a current response of about 15 nA is found for the cell appendages from the BES. This is the first report of conductivity for clostridial cell appendices and represents the basis for further studies on their role for biofilm formation and electron transfer.}, language = {en} } @article{EngelBayerHoltmannetal.2019, author = {Engel, Mareike and Bayer, Hendrik and Holtmann, Dirk and Tippk{\"o}tter, Nils and Ulber, Roland}, title = {Flavin secretion of Clostridium acetobutylicum in a bioelectrochemical system - Is an iron limitation involved?}, series = {Bioelectrochemistry}, journal = {Bioelectrochemistry}, number = {In Press, Accepted Manuscript}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1567-5394}, doi = {10.1016/j.bioelechem.2019.05.014}, year = {2019}, language = {en} } @inproceedings{EichlerSkupinThurnetal.2019, author = {Eichler, Fabian and Skupin, Marco and Thurn, Laura and Kasch, Susanne and Schmidt, Thomas}, title = {Operating limits for beam melting of glass materials}, series = {Modern Technologies in Manufacturing (MTeM 2019)}, volume = {299}, booktitle = {Modern Technologies in Manufacturing (MTeM 2019)}, number = {Article 01004}, doi = {10.1051/matecconf/201929901004}, pages = {8 Seiten}, year = {2019}, abstract = {Laser-based Additive Manufacturing (AM) processes for the use of metals out of the powder bed have been investigated profusely and are prevalent in industry. Although there is a broad field of application, Laser Powder Bed Fusion (LPBF), also known as Selective Laser Melting (SLM) of glass is not fully developed yet. The material properties of glass are significantly different from the investigated metallic material for LPBF so far. As such, the process cannot be transferred, and the parameter limits and the process sequence must be redefined for glass. Starting with the characterization of glass powders, a parameter field is initially confined to investigate the process parameter of different glass powder using LPBFprocess. A feasibility study is carried out to process borosilicate glass powder. The effects of process parameters on the dimensional accuracy of fabricated parts out of borosilicate and hints for the post-processing are analysed and presented in this paper.}, language = {en} } @inproceedings{Eggert2019, author = {Eggert, Mathias}, title = {Understanding the acceptance of smart home-based insurances}, series = {Proceedings of the 27th European Conference on Information Systems (ECIS), Stockholm \& Uppsala, Sweden, June 8-14, 2019}, booktitle = {Proceedings of the 27th European Conference on Information Systems (ECIS), Stockholm \& Uppsala, Sweden, June 8-14, 2019}, isbn = {978-1-7336325-0-8}, pages = {1 -- 15}, year = {2019}, language = {en} } @incollection{Eggert2019, author = {Eggert, Mathias}, title = {Big Data Research - How to Structure the Changes of the Past Decade?}, series = {The Art of Structuring}, booktitle = {The Art of Structuring}, publisher = {Springer}, address = {Cham}, isbn = {978-3-030-06234-7}, doi = {10.1007/978-3-030-06234-7_26}, pages = {271 -- 281}, year = {2019}, abstract = {In the past decade, many IS researchers focused on researching the phenomenon of Big Data.

In this context, cell-based biosensors can play an important role to improve the quality and increase the yield of such processes. This work describes the simultaneous analysis of the metabolic behavior of three different types of bacteria by means of a differential light-addressable potentiometric sensor (LAPS) set-up. The study includes Lactobacillus brevis, Corynebacterium glutamicum, and Escherichia coli, which are often applied in fermentation processes in bioreactors. Differential measurements were carried out to compensate undesirable influences such as sensor signal drift, and pH value variation during the measurements. Furthermore, calibration curves of the cellular metabolism were established as a function of the glucose concentration or cell number variation with all three model microorganisms. In this context, simultaneous (bio)sensing with the multi-organism LAPS-based set-up can open new possibilities for a cost-effective, rapid detection of the extracellular acidification of bacteria on a single sensor chip. It can be applied to evaluate the metabolic response of bacteria populations in a (bio)fermentation process, for instance, in the biogas fermentation process.}, language = {en} } @article{DantismRoehlenSelmeretal.2019, author = {Dantism, Shahriar and R{\"o}hlen, Desiree and Selmer, Thorsten and Wagner, Torsten and Wagner, Patrick and Sch{\"o}ning, Michael Josef}, title = {Quantitative differential monitoring of the metabolic activity of Corynebacterium glutamicum cultures utilizing a light-addressable potentiometric sensor system}, series = {Biosensors and Bioelectronics}, volume = {139}, journal = {Biosensors and Bioelectronics}, publisher = {Elsevier}, address = {Amsterdam}, doi = {10.1016/j.bios.2019.111332}, pages = {Artikel 111332}, year = {2019}, language = {en} } @incollection{DachwaldOhndorf2019, author = {Dachwald, Bernd and Ohndorf, Andreas}, title = {Global optimization of continuous-thrust trajectories using evolutionary neurocontrol}, series = {Modeling and Optimization in Space Engineering}, booktitle = {Modeling and Optimization in Space Engineering}, publisher = {Springer}, address = {Cham}, isbn = {978-3-030-10501-3}, doi = {10.1007/978-3-030-10501-3_2}, pages = {33 -- 57}, year = {2019}, abstract = {Searching optimal continuous-thrust trajectories is usually a difficult and time-consuming task.

Evolutionary neurocontrol attacks continuous-thrust optimization problems from the perspective of artificial intelligence and machine learning, combining artificial neural networks and evolutionary algorithms. This chapter describes the method and shows some example results for single- and multi-phase continuous-thrust trajectory optimization problems to assess its performance. Evolutionary neurocontrol can explore the trajectory search space more exhaustively than a human expert can do with traditional optimal-control methods. Especially for difficult problems, it usually finds solutions that are closer to the global optimum. Another fundamental advantage is that continuous-thrust trajectories can be optimized without an initial guess and without expert supervision.}, language = {en} } @article{CzarneckiBensbergAuth2019, author = {Czarnecki, Christian and Bensberg, Frank and Auth, Gunnar}, title = {Die Rolle von Softwarerobotern f{\"u}r die zuk{\"u}nftige Arbeitswelt}, series = {HMD Praxis der Wirtschaftsinformatik}, volume = {56}, journal = {HMD Praxis der Wirtschaftsinformatik}, number = {4}, publisher = {Springer}, address = {Cham}, issn = {2198-2775}, doi = {10.1365/s40702-019-00548-z}, pages = {795 -- 808}, year = {2019}, abstract = {Im Rahmen der Digitalisierung ist die zunehmende Automatisierung von bisher manuellen Prozessschritten ein Aspekt, der massive Auswirkungen auf die zuk{\"u}nftige Arbeitswelt haben wird.
