  • Variance of the Hellings-Downs correlation 
    Allen, Bruce (Ridge, NY : American Physical Society, 2023)
    Gravitational waves (GWs) create correlations in the arrival times of pulses from different pulsars. The expected correlation μ(γ) as a function of the angle γ between the directions to two pulsars was calculated by Hellings ...
  • A vertical inertial sensor with interferometric readout 
    Kranzhoff, S.L.; Lehmann, J.; Kirchhoff, R.; Carlassara, M.; Cooper, S.J.; Koch, P.; Leavey, S.; Lück, H.; Mow-Lowry, C.M.; Wöhler, J.; von Wrangel, J.; Wu, D.S. (Bristol : IOP Publ., 2022)
    High precision interferometers such as gravitational-wave detectors require complex seismic isolation systems in order to decouple the experiment from unwanted ground motion. Improved inertial sensors for active isolation ...
  • Virtual Element Method for Cross-Wedge Rolling during Tailored Forming Processes 
    Böhm, Christoph; Kruse, Jens; Stonis, Malte; Aldakheel, Fadi; Wriggers, Peter (Amsterdam [u.a.] : Elsevier, 2020)
    In this work we present an application of the virtual element method (VEM) to a forming process of hybrid metallic structures by cross-wedge rolling. The modeling of that process is embedded in a thermomechanical framework ...
  • Viscosity effects and confined cochlea-like geometry in laser-induced cavitation dynamics 
    Lengert, Liza; Lohmann, Hinnerk; Johannsmeier, Sonja; Ripken, Tammo; Maier, Hannes; Heisterkamp, Alexander; Kalies, Stefan (Berlin ; Heidelberg : Springer, 2024)
    On the path to an optoacoustic hearing implant for stimulation of residual hearing, one possibility for tone generation in liquids is the concatenation of acoustic click events, which can be realized i. a. by the acoustic ...
  • Waterproof coatings for high-power laser cavities 
    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 ...
  • Weak light performance of PERC, PERT and standard industrial solar cells 
    Krügener, Jan; Harder, Nils-Peter (London : Elsevier Ltd., 2013)
    We use SENTAURUS DEVICE simulation to investigate the effect of "passivated emitter and rear cell" (PERC) and "passivated emitter and rear, totally-diffused" (PERT) device architecture on the solar cells' weak light ...
  • Weakening of thick steel plates by laser radiation for the removal of hazardous substances 
    Hoff, Christian; Hermsdorf, Jörg; Kaierle, Stefan; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2018)
    Hazardous substances such as unexploded ordnance represent a serious threat. It is necessary to develop new methods and equipment for their elimination. For this reason, a laser ablation process is developed where the shell ...
  • X-ray Dose Rate and Spectral Measurements during Ultrafast Laser Machining Using a Calibrated (High-Sensitivity) Novel X-ray Detector 
    Mosel, Philip; Sankar, Pranitha; Düsing, Jan Friedrich; Dittmar, Günter; Püster, Thomas; Jäschke, Peter; Vahlbruch, Jan-Willem; Morgner, Uwe; Kovacev, Milutinv (Basel : MDPI, 2021)
    Ultrashort pulse laser machining is subject to increase the processing speeds by scaling average power and pulse repetition rate, accompanied with higher dose rates of X-ray emission generated during laser–matter interaction. ...
