  • 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 ...
  • Dietrich, Jörg (Hannover : Institut für Hydrologie und Wasserwirtschaft, 2019)
    Der globale Wandel stellt die Bewirtschaftung von Wasserressourcen vor neue Herausforderungen, zu denen die Bewältigung von extremen Klima- und Wettersituationen gehören wie auch der steigende Wasserbedarf für die ...

    In this article,we present an overviewof theHyIV-CNRS-SecORo (Hydralab IV-CNRS-Secondary Orography and Rotors Experiments) laboratory experiments carried out in the CNRM (Centre National de Recherches Météorologiques) large ...
  • Cheng, Xinbin; Dong, Siyu; Zhi, Song; Paschel, Sebastian; Balasa, Istvan; Ristau, Detlev; Wang, Zhanshan (London : Nature Publishing Group, 2019)
    With the ever-increasing laser power and repetition rate, thermal control of laser media is becoming increasingly important. Except for widely used air cooling or a bonded heat sink, water cooling of a laser medium is more ...

  • Kerpen, Nils B.; Schoonees, Talia; Schlurmann, Torsten (Basel : MDPI AG, 2018)
    The wave impacts on horizontal and vertical step fronts of stepped revetments is investigated by means of hydraulic model tests conducted with wave spectra in a wave flume. Wave impacts on revetments with relative step ...
  • Pförtner, S.; Oumeraci, Hocine; Kudella, M.; Kortenhaus, A. (Reston : American Society of Civil Engineers, 2010)
    The Ocean Brick System (OBS) is a modular system consisting of hollow concrete precast blocs (10m x 10m x 10m) piled up like cubes and interconnected to create a stiff, light and strong structure which can be used for ...
  • Kerpen, Nils B.; Schlurmann, Torsten (Reston : American Society of Civil Engineers, 2012)
    Hydraulic model tests at a scale of 1:10 are carried out in a 40 m x 25 m wave basin with a state-of-the-art 3D wave generator in order to collect wave overtopping data at vertical walls and dykes with topped vertical ...
  • Kerpen, Nils B.; Schoonees, Talia; Schlurmann, Torsten (Basel : MDPI AG, 2019)
    Wave overtopping - i.e., excess of water over the crest of a coastal protection infrastructure due to wave run-up - of a smooth slope can be reduced by introducing slope roughness. A stepped revetment ideally constitutes ...
  • Buchkremer, F.B.J.; Dumke, R.; Levsen, H.; Birkl, G.; Ertmer, Wolfgang (American Physical Society, 2000)
    A new echo technique to access the coherent and dissipative dynamics of atomic wave packet oscillations in trapping potentials was experimentally and systematically validated. By using this technique, the coherence time ...
  • Schendel, Alexander (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    The expansion of offshore wind energy depicts an important contribution to the fulfilment of renewable energy targets. Seeking for higher load factors, offshore wind energy steadily expands towards greater water depths. ...
  • Bongs, Kai; Burger, S.; Dettmer, S.; Hellweg, D.; Arlt, Jan J.; Ertmer, Wolfgang; Sengstock, K. (American Physical Society, 2001)
    We report on the creation of Bose-Einstein condensates of 87Rb in a specially designed hybrid, optical dipole and magnetic trap. This trap naturally allows the coherent transfer of matter waves into a pure optical dipole ...
  • Fischer, Sebastian; Fischer, Florian; Kleinschmidt, Malte; Lange, Dirk (Bielefeld : Bielefeld University, 2014)
    The investigation is about which ideas ninth form students at grammar schools and secondary modern schools have about globalisation. It shall be investigated if the perception of and judgement on globalisation-connected ...
  • Adya, Vaishali Badrish (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    Now that we have entered an era of gravitational wave astronomy, gravitational wave detectors are expected to detect several events a month (or more) in the near future. The current ground based detectors are undergoing ...
