    • CouchEdit - a modular graphical editing architecture for flexible modeling 

      Abschlussarbeit (Master; Diplom)
      Nachreiner, Leander (Universität Ulm, 2020-02-17)
      Models have long become an integral part of many system development activities. In particular, research in the field of Model Driven Engineering (MDE) strives to facilitate problem-oriented creation of complex systems. ...
    • Distributed computing on event-sourced graphs 

      Dissertation
      Erb, Benjamin (Universität Ulm, 2020-02-13)
      Modern applications with increasingly connected domain topologies require processing and programming abstractions that reflect the network structure inherent to these applications. At the same time, data-intensive applications ...
    • Nomadic virtual reality : overcoming challenges of mobile virtual reality head-mounted displays 

      Dissertation
      Gugenheimer, Jan (Universität Ulm, 2020-02-11)
      Technological advancements in the fields of optics, display technology and miniaturization have enabled high-quality virtual reality (VR) head-mounted displays (HMDs) to be used beyond research labs and become available ...
    • Aperture coupled stacked patch thin film antenna for automotive radar at 77 GHz 

      Wissenschaftlicher Artikel
      Khan, Osama; Meyer, Johannes; Baur, Klaus; Arafat, Saeed; Waldschmidt, Christian (Universität Ulm, 2019-06-10)
      A hybrid thin film multilayer antenna for automotive radar is presented in this work. A 2×8 aperture coupled stacked patch antenna array is realized on a single layer printed circuit board (PCB) using a novel thin film ...
    • Message type identification of binary network protocols using continuous segment similarity 

      Beitrag zu einer Konferenz
      Kleber, Stephan; Heijden, Rens Wouter van der; Kargl, Frank (Universität Ulm, 2020-02-07)
      Protocol reverse engineering based on traffic traces infers the behavior of unknown network protocols by analyzing observable network messages. To perform correct deduction of message semantics or behavior analysis, accurate ...
    • On the calibration of mm-Wave MIMO Radars using sparse antenna arrays for DoA estimation 

      Beitrag zu einer Konferenz
      Dürr, André; Schwarz, Dominik; Roos, Fabian; Hügler, Philipp; Bucher, Stephan; Grüner, Patrik; Waldschmidt, Christian (Universität Ulm, 2019-11-21)
      The multiple-input and multiple-output (MIMO) principle is a well-established method to improve the angular resolution of radars. Due to hardware limitations the maximum number of transmit and receive channels is often ...
    • MERCAT: A metric for the evaluation and reconsideration of certificate authority trustworthiness 

      Beitrag zu einer Konferenz
      Heinl, Michael P.; Giehl, Alexander; Wiedermann, Norbert; Plaga, Sven; Kargl, Frank (Universität Ulm, 2019-11-11)
      Public key infrastructures (PKIs) build the foundation for secure communication of a vast majority of cloud services. In the recent past, there has been a series of security incidents leading to increasing concern regarding ...
