  • Evaluation of different calibration strategies for large scale continuous hydrological modelling 
    Wallner, Markus; Haberlandt, Uwe; Dietrich, J. (Göttingen : Copernicus GmbH, 2012)
    For the analysis of climate impact on flood flows and flood frequency in macroscale river basins, hydrological models can be forced by several sets of hourly long-term climate time series. Considering the large number of ...
  • Hydrological model calibration for derived flood frequency analysis using stochastic rainfall and probability distributions of peak flows 
    Haberlandt, Uwe; Radtke, I. (Göttingen : Copernicus GmbH, 2014)
    Derived flood frequency analysis allows the estimation of design floods with hydrological modeling for poorly observed basins considering change and taking into account flood protection measures. There are several possible ...
  • Improved Calibration Procedure for Wireless Inertial Measurement Units without Precision Equipment 
    Webering, Fritz; Kleinjohann, Sarah; Stanislawski, Nils; Blume, Holger ([Erscheinungsort nicht ermittelbar] : ArXiv, 2022)
    Inertial measurement units (IMUs) are used in medical applications for many different purposes. However, an IMU's measurement accuracy can degrade over time, entailing re-calibration. In their 2014 paper, Tedaldi et al. ...
  • LISA pathfinder performance confirmed in an open-loop configuration: Results from the free-fall actuation mode 
    Armano, M.; Audley, H.; Baird, J.; Binetruy, P.; Born, M.; Bortoluzzi, D.; Castelli, E.; Cavalleri, A.; Cesarini, A.; Cruise, A.M.; Danzmann, K.; De Deus Silva, M.; Diepholz, I.; Dixon, G.; Dolesi, R.; Ferraioli, L.; Ferroni, V.; Fitzsimons, E.D.; Freschi, M.; Gesa, L.; Gibert, F.; Giardini, D.; Giusteri, R.; Grimani, C.; Grzymisch, J.; Harrison, I.; Hartig, M.-S.; Heinzel, G.; Hewitson, M.; Hollington, D.; Hoyland, D.; Hueller, M.; Inchauspé, H.; Jennrich, O.; Jetzer, P.; Karnesis, N.; Kaune, B.; Korsakova, N.; Killow, C.J.; Lobo, J.A.; Liu, L.; López-Zaragoza, J.P.; Maarschalkerweerd, R.; Mance, D.; Meshksar, N.; Martín, V.; Martin-Polo, L.; Martino, J.; Martin-Porqueras, F.; Mateos, I.; McNamara, P.W.; Mendes, J.; Mendes, L.; Nofrarias, M.; Paczkowski, S.; Perreur-Lloyd, M.; Petiteau, A.; Pivato, P.; Plagnol, E.; Ramos-Castro, J.; Reiche, J.; Robertson, D.I.; Rivas, F.; Russano, G.; Slutsky, J.; Sopuerta, C.F.; Sumner, T.; Texier, D.; Thorpe, J.I.; Vetrugno, D.; Vitale, S.; Wanner, G.; Ward, H.; Wass, P.J.; Weber, W.J.; Wissel, L.; Wittchen, A.; Zweifel, P. (College Park, MD : American Physical Society, 2019)
