    • 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 ...
    • Can music foster learning – effects of different text modalities on learning and information retrieval 

      Wissenschaftlicher Artikel
      Lehmann, Janina A. M.; Seufert, Tina (Universität Ulm, 2018-01-09)
      This study investigates the possibilities of fostering learning based on differences in recall and comprehension after learning with texts which were presented in one of three modalities: either in a spoken, written, or ...
    • A complex low-RCS antenna system for the placement of mm-wave automotive radars behind car bumpers 

      Beitrag zu einer Konferenz
      Vasanelli, Claudia; Bögelsack, Frank; Waldschmidt, Christian (Universität Ulm, 2018-12-10)
      Automotive radars are one of the key sensor technologies to develop reliable fully-automated cars. They are usually installed behind the bumper of the vehicle and therefore, multiple reflections can occur. The multiple ...
    • 160-GHz radar proximity sensor with distributed and flexible antennas for collaborative robots 

      Wissenschaftlicher Artikel
      Geiger, Martin; Waldschmidt, Christian (Universität Ulm, 2019-01-09)
      There is a growing demand for collaborative robots in order to improve the efficiency of industrial processes and to push Industry 4.0 forward. The challenge for these robots is the compliance of the safety regulations to ...
    • Systems of bounded rational agents with information-theoretic constraints 

      Wissenschaftlicher Artikel
      Gottwald, Sebastian; Braun, Daniel A. (Universität Ulm, 2019-01-18)
      Specialization and hierarchical organization are important features of efficient collaboration in economical, artificial, and biological systems. Here, we investigate the hypothesis that both features can be explained by ...
    • On hardware implementations of stepped-carrier OFDM radars 

      Beitrag zu einer Konferenz
      Schweizer, Benedikt; Schindler, Daniel; Knill, Christina; Hasch, Jürgen; Waldschmidt, Christian (Universität Ulm, 2018-08-20)
      Orthogonal frequency-division multiplexing (OFDM) is a promising candidate for future digital-centric radar systems. One major limitation for practical implementations is the required sampling rate in the order of GHz, ...
    • Expanding the unambiguous velocity limitation of the stepped-carrier OFDM radar scheme 

      Beitrag zu einer Konferenz
      Schweizer, Benedikt; Schindler, Daniel; Knill, Christina; Hasch, Jürgen; Waldschmidt, Christian (Universität Ulm, 2018-11-29)
      The main limitation for the practical implementation of OFDM radars is the required high sampling rate of AD/DA converters. It can be solved by using a stepped-carrier OFDM scheme. Thereby, the same range and Doppler ...
