    Over the last years, Active Middle Ear Implants (AMEIs) and Direct Acoustic Cochlear Implants (DACIs) have become well established as a therapy for hearing impaired patients who are not suited for a provision of a hearing ...
  • Mutschall, Marcel (Hamburg : Aircraft Design and Systems Group (AERO), Department of Automotive and Aeronautical Engineering, Hamburg University of Applied Sciences, 2018)
    Ziel – Die Zeit die ein Flugzeug benötigt, um auf eine bestimmte Höhe zu steigen (die Steigzeit) kann mit einer Formel berechnet werden, die vereinfachend annimmt, dass die Steiggeschwindigkeit über dem gesamten Steigflug ...
  • Lehnert, Jan (Hamburg : Aircraft Design and Systems Group (AERO), Department of Automotive and Aeronautical Engineering, Hamburg University of Applied Sciences, 2018)
    Diese Projektarbeit beschäftigt sich mit dem Thema der Berechnung des Betriebsleermassenanteils im Flugzeugentwurf. Bekannte Berechnungsverfahren nach Torenbeek, Raymer, Marckwardt und Loftin werden auf Qualität und ...
  • Graf, Marcel; Ullmann, Madlen; Korpala, Grzegorz; Wester, Hendrik; Awiszus, Birgit; Kawalla, Rudolf; Behrens, Bernd-Arno (Basel : MDPI AG, 2018)
    Developments in technology rely increasingly on the numerical simulation of single process steps up to whole process chains using commercially available or user-written software systems, mostly based on the finite element ...
  • Klimov, G.; Maier, H.-J.; Beniyash, A.; Hassel, T. (Bristol : Institute of Physics Publishing, 2018)
    Lightweight construction materials, in particular aluminum alloys, have recently become more important as construction materials due to their low weight with high strength and sufficient wear and corrosion properties. In ...
  • Fuchs, Julia; Mueller, Marc; Daxböck, Christine; Stückler, Manuela; Lang, Ingrid; Leitinger, Gerd; Bock, Elisabeth; El-Heliebi, Amin; Moser, Gerit; Glasmacher, Birgit; Brislinger, Dagmar (Heidelberg : Springer Verlag, 2018)
    Histological processing of thermosensitive electrospun poly(ε-caprolactone)/poly(l-lactide) (PCL/PLA) scaffolds fails, as poly(ε-caprolactone) (PCL) is characterized by its low-melting temperature (Tm = 60 °C). Here, we ...
  • Hassel, T.; Klimov, G.; Beniyash, A. (Bristol : Institute of Physics Publishing, 2018)
    One of the disadvantages of the non-vacuum electron beam (NVEB) systems is a high acceleration voltage, which leads to an increase of defence against X-ray radiation. Due to the reduced acceleration voltage. On the one ...
  • Brüge, Niklas; Kranich, Felix (Hamburg : Aircraft Design and Systems Group (AERO), Department of Automotive and Aeronautical Engineering, Hamburg University of Applied Sciences, 2018)
    Diese Projektarbeit versucht zu erklären, warum Flugzeuge mit drei oder vier Triebwerken kaum noch verkauft werden. Dabei wird insbesondere der Vermutung nachgegangen, dass Flugzeuge mit einer größeren Anzahl an Triebwerken ...
  • Pape, Arlind (Hamburg : Aircraft Design and Systems Group (AERO), Department of Automotive and Aeronautical Engineering, Hamburg University of Applied Sciences, 2018)
    In dieser Projektarbeit geht es um die Abschätzung von Massen der Hauptbaugruppen großer ziviler Verkehrsflugzeuge (MTOM > 40 t), sowie um die Abschätzung der Betriebsleermasse. Die Projektarbeit analysiert die 2013 im ...
  • Yildiz, B.; Förster, P.; Feuerle, T.; Hecker, P.; Bugow, S.; Helber, S. (Basel : MDPI AG, 2018)
    The turnaround process constitutes an important part of the air transportation system. Airports often represent bottlenecks in air traffic management (ATM), thus operations related to the preparation of the aircraft for ...
  • Gutknecht, F.; Gerstein, G.; Traphöner, H.; Clausmeyer, T.; Nürnberger, F. (Bristol : Institute of Physics Publishing, 2018)
    For many metals, a transient variation of the yield stress can be observed when changing the orientation of a load-path. Such behavior affects the manufacturing process itself, e.g. by increasing forming forces, altered ...
