  • Optimierte Softwarekomponentenverteilung in bestehenden vernetzten eingebetteten Systemen 

    Klee, Hannes (Universität Ulm, 2019-11-20)
    Moderne verteile Systeme müssen heutzutage eine große Anzahl an Anforderungen erfüllen. Dies führt zu einer stetig wachsenden Anzahl an Funktionen, die auf unterschiedlichen Recheneinheiten ausgeführt werden müssen. Bei ...
  • Comparison of direct digitization current sensing circuits for EIS 

    Beitrag zu einer Konferenz
    Rajabzadeh, Mahdi; Häberle, Matthias; Ortmanns, Maurits (Universität Ulm, 2019-08-05)
    In this work, a qualitative comparison between state of the art current recorders for biomedical applications is presented. Prior work showed that direct digitizing frontends outweight their analog counterparts. This work ...
  • Evaluation of single-bit sigma-delta modulator DAC for electrical impedance spectroscopy 

    Beitrag zu einer Konferenz
    Rajabzadeh, Mahdi; Becker, Joachim; Ortmanns, Maurits (Universität Ulm, 2017-03-29)
    In this paper, single-bit sigma-delta modulator based digital-analog conversion (DAC) is evaluated as potential driver in multichannel electrical impedance spectroscopy (EIS) arrays. The sinusoidal excitation with typical ...
  • Is distributed database evaluation cloud-ready? 

    Beitrag zu einer Konferenz
    Seybold, Daniel; Domaschka, Jörg (Universität Ulm, 2017-09-09)
    The database landscape has significantly evolved over the last decade as cloud computing enables to run distributed databases on virtually unlimited cloud resources. Hence, the already non-trivial task of selecting and ...
  • Comparison of 2D and 3D compressed sensing for high-resolution TDM-MIMO radars 

    Beitrag zu einer Konferenz
    Roos, Fabian; Hügler, Philipp; Knill, Christina; Tovar Torres, Lizette Lorraine; Appenrodt, Nils; Dickmann, Jürgen; Waldschmidt, Christian (Universität Ulm, 2019)
    In order to enhance the resolution of radar sensors, the sampling of the different measurement domains range, Doppler, and direction-of-arrival can be improved. This, for example, leads to the application of a sparse array ...
  • Fully integrated, multichannel IC for brain machine interfaces 

    Haas, Michael (Universität Ulm, 2019-10-25)
    The rapid progress of technology in the semiconductor industry over the last decades allowed the development of a whole new generation of fully integrated neuromodulators. By an increase in the level of integration, new ...
  • Channel coding for hardware-intrinsic security 

    Müelich, Sven (Universität Ulm, 2019-10-24)
    Hardware-intrinsic security studies cryptographic methods, whose implementations are assisted by some specific physical properties of the hardware on which they are executed. Physical Unclonable Functions (PUFs) are a ...
  • A noncoherent massive MIMO system employing beamspace techniques 

    Wissenschaftlicher Artikel
    Bucher, Stephan; Yammine, George; Fischer, Robert F. H.; Waldschmidt, Christian (Universität Ulm, 2019-09-23)
    Noncoherent detection schemes are an appealing and low-complexity alternative in multi-user massive MIMO uplink systems compared to classical coherent detection algorithms, since no actual channel knowledge is required ...
  • Study on human-in-the-loop sensing in urban environment analysis 

    Matsuda, Yuki (Universität Ulm, 2019-10-11)
    Due to the widespread of mobile devices such as smartphones, we can get the appropriate information anytime, anywhere according to the surrounding environments and the human conditions, called ``contexts.'' In order to ...
  • Measuring the stability of emotion specific empathy using the German version of the Emotion Specific Empathy Questionnaire (ESE) 

    Abschlussarbeit (Bachelor)
    Pawlitzki, Markus (Universität Ulm, 2019-10-09)
    Knowing what another person is feeling and feeling that same emotion too is what empathy enables us to do. However, since there are various different emotions, the question becomes if we feel the same empathetic response ...
