  • Random multiplexing for an MIMO-OFDM radar with compressed sensing-based reconstruction 

    Wissenschaftlicher Artikel
    Knill, Christina; Roos, Fabian; Schweizer, Benedikt; Schindler, Daniel; Waldschmidt, Christian (Universität Ulm, 2019-03-14)
    In many applications, the direction of arrival (DoA) information of the radar signal plays a decisive role in target localization. A multiple-input multiple-output (MIMO) radar allows to obtain the position of an object ...
  • Adaptive dialogue management for a script knowledge based conversational assistant 

    Abschlussarbeit (Master; Diplom)
    Feustel, Isabel; Miehle, Juliana (Universität Ulm, 2019-05-14)
    The spoken dialogue systems today already fulfill many requirements, and their human-machine interaction works very well. Nevertheless, the users still adapt their communication style to these system. In order to develop ...
  • Bounded rational decision-making from elementary computations that reduce uncertainty 

    Wissenschaftlicher Artikel
    Gottwald, Sebastian; Braun, Daniel A. (Universität Ulm, 2019-04-06)
    In its most basic form, decision-making can be viewed as a computational process that progressively eliminates alternatives, thereby reducing uncertainty. Such processes are generally costly, meaning that the amount of ...
  • Compressed sensing based single snapshot DoA estimation for sparse MIMO radar arrays 

    Beitrag zu einer Konferenz
    Roos, Fabian; Hügler, Philipp; Tovar Torres, Lizette Lorraine; Knill, Christina; Schlichenmaier, Johannes; Vasanelli, Claudia; Appenrodt, Nils; Dickmann, Jürgen; Waldschmidt, Christian (Universität Ulm, 2019-04-25)
    The angular resolution of a radar system can be enhanced with an increasing antenna aperture. Instead of using more antenna elements, the distances in the aperture can be increased with a sparse array. To mitigate the high ...
  • SiGe BiCMOS circuits and system demonstrators for high range resolution mm-wave radars 

    Yuan, Shuai (Universität Ulm, 2019-04-11)
    The potential and performance of the silicon-based millimeter wave radar building blocks and systems have been demonstrated in many ways, including a wideband chirp generator, several high-performance frequency multiplier ...
  • Combining safety and security threat modeling to improve automotive penetration testing 

    Abschlussarbeit (Master; Diplom)
    Wolf, Michael (Universität Ulm, 2019-04-03)
    Newer technologies like connectivity and autonomy in the automotive sector increases the need for stronger security and for its evaluation penetration tests. In order to focus the tests first on the most critical possible ...
  • Konzeption und Umsetzung von Live-Migration für Docker-Container 

    Abschlussarbeit (Bachelor)
    Winkelhofer, Sascha (Universität Ulm, 2019-03-21)
    Durch die zunehmende Umsetzung von Microservice-Ansätzen unter Nutzung von Container-Technologien zur Abstraktion und Isolation wird auch die Nachfrage nach Portabilität größer. Ein Weg diese zu erreichen ohne einen Service ...
  • A metric to assess the trustworthiness of certificate authorities 

    Abschlussarbeit (Master; Diplom)
    Heinl, Michael P. (Universität Ulm, 2019-03-14)
    In the recent past, there has been a series of security incidents leading to increasing concern regarding the trust model currently employed by public key infrastructures. One of the key criticisms is the architecture’s ...
  • Systematische Security-Tests von Kraftfahrzeugen 

    Ring, Martin (Universität Ulm, 2019-03-14)
    Kraftfahrzeuge waren abgeschlossene Systeme und daher für digitale Angriffe weitestgehend uninteressant. Dies hat sich in den vergangenen Jahren stark geändert, es halten immer mehr drahtlose Schnittstellen Einzug und seit ...
  • From curse to blessing: harnessing geomagnetic field disturbances for ubiquitous navigation 

    Frassl, Martin (Universität Ulm, 2019-03-14)
    Determination of location is a fundamental problem with a long history of research and technical solutions. The research described in this thesis focuses on the use of a specific signal, the magnetic field, to achieve ...
