    The paper discusses the possibilities of incorporating sensors and indicators into the environment of an Industry 4.0 digital factory. The concept of Industry 4.0 (I4.0) is characterized via a brief description of the RAMI ...

  • The Asset Administration Shell of Operator in the Platform of Industry 4.0 

    Marcoň, Petr; Zezulka, František; Arm, Jakub; Benešl, Tomáš; Veselý, Ivo; Bradáč, Zdeněk; Diedrich, Christian; Schröder, Tizian; Belyaev, Alexander (IEEE, 2018-12-05)
    We discuss the Asset Administration Shell (AAS) concept of Industry 4.0 (I4.0), characterizing the current status of industrial automation and outlining the advantages of more deeply digitized manufacturing where the AAS ...

  • A Novel Tool for Supervised Segmentation Using 3D Slicer 

    Chalupa, Daniel; Mikulka, Jan (MDPI, 2018-11-12)
    The rather impressive extension library of medical image-processing platform 3D Slicer lacks a wide range of machine-learning toolboxes. The authors have developed such a toolbox that incorporates commonly used machine-learning ...

  • Testing an Impedance Non-destructive Method to Evaluate Steel-Fiber Concrete Samples 

    Komárková, Tereza; Fiala, Pavel; Steinbauer, Miloslav; Roubal, Zdeněk (Institute of Measurement Science of Slovak Academy of Sciences, 2018-03-01)
    The paper discusses tests related to the evaluation of the density and orientation of fibers in a composite material. Compared to the approaches used to date, the proposed technique is based on the evaluation of the ...

  • The Effect of a Spiral Gradient Magnetic Field on the Ionic Conductivity of Water 

    Bartušek, Karel; Marcoň, Petr; Fiala, Pavel; Máca, Josef; Dohnal, Přemysl (MDPI, 2017-09-02)
    We discuss the experimental verification of changes in the structure of a liquid water sample inserted in a special spiral “gradient” magnetic field. The magnetic flux components are characterized by a high degree of ...
