  • Reinecke, Tobias; Kirk, Ansgar T.; Heptner, Andre; Niebuhr, D.; Böttger, S.; Zimmermann, Stefan (College Park, MA : American Institute of Physics (AIP), 2016)
    For the ionization of gaseous samples, most ion mobility spectrometers employ radioactive ionization sources, e.g., containing 63Ni or 3H. Besides legal restrictions, radioactive materials have the disadvantage of a constant ...
  • Feldkord, Sven; Reit, Marco; Mathis, Wolfgang (Göttingen : Copernicus GmbH, 2017)
    Recently, for modeling biological amplification processes, nonlinear amplifiers based on the supercritical Andronov-Hopf bifurcation have been widely analyzed analytically. For technical realizations, digital systems have ...
  • Shamshiri, Roghayeh; Nahavandchi, Hossein; Motagh, Mahdi; Hooper, Andy (Basel : MDPI AG, 2018)
    Combining persistent scatterers (PS) and distributed scatterers (DS) is important for effective displacement monitoring using time-series of SAR data. However, for large stacks of synthetic aperture radar (SAR) data, the ...
  • Golestani, Hossein; Meuel, Holger; Voges, Jan; Laude, Thorsten; Erfurt, Johannes; Lim, Wang; Schwarz, Heiko; Marpe, Detlev; Wiegand, Thomas; Genser, Nils; Seiler, Jürgen; Kaup, André; Munderloh, Marco; Dedjouong, Armel; Bahlau, Sascha; Klemt-Albert, Katharina; Ostermann, Jörn; Samayoa, Yasser; Purushothaman, Suraja Koottachiara Nikarth (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018-07-18)

  • Cochems, Philipp; Kirk, Ansgar T.; Bunert, Erik; Runge, M.; Goncalves, P.; Zimmermann, Stefan (College Park, MA : American Institute of Physics (AIP), 2015)
    Non-radioactive electron sources are of great interest in any application requiring the emission of electrons at atmospheric pressure, as they offer better control over emission parameters than radioactive electron sources ...
  • Abbott, B.P.; Abbott, R.; Abbott, T.D.; Abernathy, M.R.; Acernese, F.; et al.; LIGO Scientific Collaboration; Virgo Collaboration (College Park, MD : American Physical Society, 2016)
    On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory simultaneously observed a transient gravitational-wave signal. The signal sweeps upwards in frequency from ...
  • Ahrens, Andreas; Sandmann, Andre; Bremer, Kort; Roth, Bernhard; Lochmann, Steffen (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    In this paper multiple-input multiple-output (MIMO) signal processing is investigated for fibre optic sensor applications. A (2 × 2) MIMO implementation is realized by using lower-order and higher-order mode groups of a ...

    Proceedings of the 4th Summer School on Video Compression and Processing (SVCP) 2018
  • Denicke, Eckhard; Armbrecht, Gunnar; Rolfes, Ilona (Cambridge : Cambridge University Press, 2010)
    This contribution deals with guided radar distance measurements in the field of industrial tank level control. The aim is to achieve a submillimeter gauging accuracy even when conducting the measurement within a highly ...
  • Denkena, Berend; Dahlmann, Dominik; Damm, J. (Amsterdam : Elsevier, 2015)
    Modern monitoring systems in machine tools are able to detect process errors promptly. Still, the application of monitoring systems is restricted by the complexity of parameterization for save monitoring. In most cases, ...
  • Nogueira, Waldo; Litvak, Leonid; Edler, Bernd; Ostermann, Jörn; Büchner, Andreas (Heidelberg : Springer Verlag, 2009)
    In contemporary cochlear implant systems, the audio signal is decomposed into different frequency bands, each assigned to one electrode. Thus, pitch perception is limited by the number of physical electrodes implanted into ...
