M. (Bristol : IOP Publishing Ltd., 2019)
    Astrophysical sources of gravitational waves, such as binary neutron star and black hole mergers or core-collapse supernovae, can drive relativistic outflows, giving rise to non-thermal high-energy emission. High-energy ...
  • Panning, Lars; Sextro, Walter; Popp, Karl (London : Hindawi Limited, 2003)
    One of the main tasks in the design of turbomachines like turbines, compressors, and fans is to increase the reliability and efficiency of the arrangement. Failures due to blade cracks are still a problem and have to be ...
  • Wolff, Julius; Kolditz, Torge; Fei, Yangyang; Raatz, Annika (Amsterdam : Elsevier B.V., 2018)
    While joining tolerances, and therefore forces, are known in the assembly process, the determination of disassembly forces is not possible. This is caused by changes of the product properties during the product operation, ...
  • Nehring, Stefan; Boestfleisch, Christian; Buhmann, Anne K.; Papenbrock, Jutta (Helsinki : Regional Euro-Asian Biological Invasions Centre Oy (REABIC), 2012)
    Three lineages (G1, G2 and G3) within the toxic invasive ergot fungus Claviceps purpurea (Fries) Tulasne are known; these should be recognized as unique species, or at least as varieties. On 2 November 2011, a very dense, ...
