This paper firstly presents the structural analysis performed on the sail to understand its elastic behavior. The results are then used in attitude and orbital simulations. The model considers the main forces and torques that a satellite experiences in low-Earth orbit coupled with the sail deformation. Doing the simulations for varying initial conditions in attitude and rotation rate, the results show initial states to avoid and maximum rotation rates reached for correct and faulty deployment of the sail. Lastly comparisons with the classic flat sail model are carried out to test the hypothesis that the elastic behavior does play a role in the attitude and orbital behavior of the sail}, language = {en} } @article{PilasMarianoKeusgenetal.2015, author = {Pilas, Johanna and Mariano, K. and Keusgen, M. and Selmer, Thorsten and Sch{\"o}ning, Michael Josef}, title = {Optimization of an Enzyme-based Multi-parameter Biosensor for Monitoring Biogas Processes}, series = {Procedia Engineering}, volume = {120}, journal = {Procedia Engineering}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1877-7058}, doi = {10.1016/j.proeng.2015.08.702}, pages = {532 -- 535}, year = {2015}, language = {en} } @article{PilasIkenSelmeretal.2015, author = {Pilas, Johanna and Iken, Heiko and Selmer, Thorsten and Keusgen, Michael and Sch{\"o}ning, Michael Josef}, title = {Development of a multi-parameter sensor chip for the simultaneous detection of organic compounds in biogas processes}, series = {Physica status solidi (a)}, volume = {212}, journal = {Physica status solidi (a)}, number = {6}, publisher = {Wiley}, address = {Weinheim}, issn = {1862-6319}, doi = {10.1002/pssa.201431894}, pages = {1306 -- 1312}, year = {2015}, abstract = {An enzyme-based multi-parameter biosensor is developed for monitoring the concentration of formate, d-lactate, and l-lactate in biological samples. The sensor is based on the specific dehydrogenation by an oxidized β-nicotinamide adenine dinucleotide (NAD+)-dependent dehydrogenase (formate dehydrogenase, d-lactic dehydrogenase, and l-lactic dehydrogenase, respectively) in combination with a diaphorase from Clostridium kluyveri (EC 1.8.1.4). The enzymes are immobilized on a platinum working electrode by cross-linking with glutaraldehyde (GA). The principle of the determination scheme in case of l-lactate is as follows: l-lactic dehydrogenase (l-LDH) converts l-lactate into pyruvate by reaction with NAD+. In the presence of hexacyanoferrate(III), the resulting reduced β-nicotinamide adenine dinucleotide (NADH) is then regenerated enzymatically by diaphorase. The electrochemical detection is based on the current generated by oxidation of hexacyanoferrate(II) at an applied potential of +0.3 V vs. an Ag/AgCl reference electrode. The biosensor will be electrochemically characterized in terms of linear working range and sensitivity. Additionally, the successful practical application of the sensor is demonstrated in an extract from maize silage.}, language = {en} } @article{Pietsch2015, author = {Pietsch, Wolfram}, title = {Augmenting voice of the customer analysis by analysis of belief}, series = {QFD-Forum}, journal = {QFD-Forum}, number = {30}, issn = {1431-6951}, pages = {1 -- 5}, year = {2015}, language = {en} } @inproceedings{PhamStaat2015, author = {Pham, Phu Tinh and Staat, Manfred}, title = {A simplification for shakedown analysis of hardening structures}, series = {Conference proceedings of the YIC GACM 2015 : 3rd ECCOMAS Young Investigators Conference and 6th GACM Colloquium on Computational Mechanics , Aachen , Germany, 20.07.2015 - 23.07.2015 / ed.: Stefanie Elgeti ; Jaan-Willem Simon}, booktitle = {Conference proceedings of the YIC GACM 2015 : 3rd ECCOMAS Young Investigators Conference and 6th GACM Colloquium on Computational Mechanics , Aachen , Germany, 20.07.2015 - 23.07.2015 / ed.: Stefanie Elgeti ; Jaan-Willem Simon}, publisher = {RWTH Aachen University}, address = {Aachen}, organization = {ECCOMAS Young Investigators Conference <3, 2015, Aachen>}, pages = {1 -- 4}, year = {2015}, language = {en} } @article{PfaffSchmidtPinders2015, author = {Pfaff, Raphael and Schmidt, Bernd and Pinders, Udo}, title = {Energieeffizienz steigern durch Rekuperationseinrichtungen}, series = {Deine Bahn}, journal = {Deine Bahn}, number = {5}, publisher = {Eisenbahn-Fachverlag}, address = {Mainz}, issn = {0172-4479}, pages = {50 -- 53}, year = {2015}, language = {de} } @article{Pfaff2015, author = {Pfaff, Raphael}, title = {Praxisnahe Ausbildung im Fach Schienenfahrzeugtechnik}, series = {Deine Bahn}, journal = {Deine Bahn}, number = {8}, publisher = {Eisenbahn-Fachverlag}, address = {Mainz}, issn = {0172-4479}, pages = {52 -- 55}, year = {2015}, language = {de} } @inproceedings{PeloniCeriottiDachwald2015, author = {Peloni, Alessandro and Ceriotti, Matteo and Dachwald, Bernd}, title = {Solar-Sailing Trajectory Design for Close-up NEA Observations Mission}, series = {4th IAA Planetary Defense Conference - PDC 2015, 13-17 April 2015, Frascati, Roma, Italy}, booktitle = {4th IAA Planetary Defense Conference - PDC 2015, 13-17 April 2015, Frascati, Roma, Italy}, pages = {21 S.}, year = {2015}, language = {de} } @inproceedings{PeloniCeriottiDachwald2015, author = {Peloni, A. and Ceriotti, M. and Dachwald, Bernd}, title = {Preliminary trajectory design of a multiple NEO rendezvous mission through solar sailing}, series = {Proceedings of the International Astronautical Congress, IAC, Vol. 8, 2014}, booktitle = {Proceedings of the International Astronautical Congress, IAC, Vol. 8, 2014}, publisher = {Curran}, address = {Red Hook, NY}, isbn = {978-1-63439-986-9}, pages = {5352 -- 5366}, year = {2015}, language = {en} } @article{PaulssenHoehrHouetal.2015, author = {Paulßen, Elisabeth and Hoehr, Cornelia and Hou, Xinchi and Hanemaayer, Victoire and Zeisler, Stefan and Adam, Michael J. and Ruth, Thomas J. and Celler, Anna and Buckley, Ken and Benard, Francois and Schaffer, Paul}, title = {Production of Y-86 and other radiometals for research purposes using a solution target system}, series = {Nuclear medicine and biology}, volume = {42}, journal = {Nuclear medicine and biology}, number = {11}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1872-9614}, doi = {10.1016/j.nucmedbio.2015.06.005}, pages = {842 -- 849}, year = {2015}, language = {en} } @inproceedings{OttenSchmidWeber2015, author = {Otten, D. and Schmid, M. and Weber, Tobias}, title = {Advances In Sheet Metal-Forming: Reduction Of Tooling Cost By Methodical Optimization}, series = {Proceedings of SAMPE Europe Conference, Amiens , France}, booktitle = {Proceedings of SAMPE Europe Conference, Amiens , France}, year = {2015}, language = {en} } @article{OlbertzSturm2015, author = {Olbertz, Klaus and Sturm, Nora}, title = {R{\"u}ckzahlungsvereinbarungen f{\"u}r Fortbildungskosten - welche Spielregeln gelten?}, series = {Gesellschafts- und Wirtschaftsrecht : GWR}, journal = {Gesellschafts- und Wirtschaftsrecht : GWR}, publisher = {Beck}, address = {M{\"u}nchen}, issn = {1868-1816}, pages = {510 -- 513}, year = {2015}, language = {de} } @article{Olbertz2015, author = {Olbertz, Klaus}, title = {Abschlagsfreie Rente mit 63 - Die wichtigsten Fragestellungen und L{\"o}sungen f{\"u}r die Praxis}, series = {NWB - Steuer- und Wirtschaftsrecht}, journal = {NWB - Steuer- und Wirtschaftsrecht}, number = {15}, publisher = {NWB Verlag}, address = {Herne}, issn = {1860-9449}, pages = {1263 -- 1270}, year = {2015}, language = {de} } @book{Olbertz2015, author = {Olbertz, Klaus}, title = {Rente mit 63 : Voraussetzungen, Hinzuverdienstgrenzen, Abschl{\"a}ge, Auswirkungen}, publisher = {nwb}, address = {Herne}, isbn = {978-3-482-66171-6}, pages = {35 S. : graph.
