  • Binnewies, T.; Wilpers, G.; Sterr, U.; Riehle, F.; Helmcke, J.; Mehlstäubler, T.E.; Rasel, Ernst Maria; Ertmer, Wolfgang (American Physical Society, 2001)
    Ultracold atoms at temperatures close to the recoil limit have been achieved by extending Doppler cooling to forbidden transitions. A cloud of 40Ca atoms has been cooled and trapped to a temperature as low as 6μK by operating ...
  • Feng, G.; George-Williams, H.; Patelli, E.; Coolen, F.P.A.; Beer, M. (London : Taylor & Francis Group, 2018)
    Common-Cause Failures (CCF) impose severe consequences on a complex system’s reliability and overall performance. A more realistic assessment, therefore, of the survivability of the system requires an adequate consideration ...
  • Yildiz, Bekir; Förster, Peter; Feuerle, Thomas; Hecker, Peter; Bugow, Stefan; Helber, Stefan (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 ...
  • Pohle, Linus; Tatzko, Sebastian; Panning-von Scheidt, Lars; Wallaschek, Jörg (Warsaw : Polish Society of Theoretical and Allied Mechanics, 2017)
    Small deviations between turbine blades exist due to manufacturing tolerances or material inhomogeneities. This effect is called mistuning and usually causes increased vibration amplitudes and also a lower service life ...
  • Behrensdorf, J.; Broggi, M.; Beer, M. (London : Taylor & Francis Group, 2018)
    The effect of natural and man made disasters on critical infrastructures are substantial, as evident from recent history. Break downs of critical systems such as electrical power grids, water supply networks, communication ...
  • Lörch, Niels; Qian, Jiang; Clerk, Aashish; Marquardt, Florian; Hammerer, Klemens (New York : American Physical Society, 2014)
    Optomechanical systems can exhibit self-sustained limit cycles where the quantum state of the mechanical resonator possesses nonclassical characteristics such as a strongly negative Wigner density, as was shown recently ...
  • Kruse, C.; Rottensteiner, F.; Heipke, C. (London : International Society for Photogrammetry and Remote Sensing, 2019)
    Many countries were the target of air strikes during the Second World War. The aftermath of such attacks is felt until today, as numerous unexploded bombs or duds still exist in the ground. Typically, such areas are ...

  • Khodadadian, Amirreza; Parvizi, Maryam; Abbaszadeh, Mostafa; Dehghan, Mehdi; Heitzinger, Clemens (Heidelberg : Springer Verlag, 2019)
    In this paper, we employ the multilevel Monte Carlo finite element method to solve the stochastic Cahn–Hilliard–Cook equation. The Ciarlet–Raviart mixed finite element method is applied to solve the fourth-order equation. ...

    A multiple scale model approach is presented in order to investigate Al2O3 thin film growth in the framework of an existing Ion Beam Sputtering (IBS) coating process. Therefore, several simulation techniques are combined ...
  • Bureick, Johannes; Alkhatib, Hamza; Neumann, Ingo (Berlin : De Gruyter, 2016)
    In many geodetic engineering applications it is necessary to solve the problem of describing a measured data point cloud, measured, e. g. by laser scanner, by means of free-form curves or surfaces, e. g., with B-Splines ...
