  • Coupled Numerical Model of Vibration-Based Harvester 

    Zukal, Jiří; Fiala, Pavel; Szabó, Zoltán; Dědková, Jarmila; Pernica, Roman (MDPI, 2020-04-15)
    Herein, the authors publish the complex design of a numerical coupled model of a vibration-based harvester that transforms mechanical vibrations into electric energy. A numerical model is based on usage of the finite element ...
  • 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 ...
  • The Evaluation of Noise Spectroscopy Tests 

    Fiala, Pavel; Drexler, Petr; Nešpor, Dušan; Szabó, Zoltán; Mikulka, Jan; Polívka, Jiří (MDPI, 2016-12-10)
    The paper discusses mathematical tools to evaluate novel noise spectroscopy based analysis and describes, via physical similarity, the mathematical models expressing the quantitative character of the modeled task. Using ...
  • A Non-Destructive Impedance Method Using Resonance to Evaluate the Concentration of Steel Fibers in Concrete 

    Bachorec, Tibor; Fiala, Pavel; Steinbauer, Miloslav; Roubal, Zdeněk (DE GRUYTER POLAND SP ZOO, 2018-10-08)
    Steel-fiber reinforced concrete is a composite material characterized by outstanding tensile properties and resistance to cracking. The concrete, however, exhibits such characteristics only on the condition that the steel ...
  • A Sensor System for Detecting and Localizing Partial Discharges in Power Transformers with Improved Immunity to Interferences 

    Drexler, Petr; Čáp, Martin; Fiala, Pavel; Steinbauer, Miloslav; Kadlec, Radim; Kaška, Miloš; Kočiš, Lubomír (MDPI, 2019-02-22)
    The paper reports on the solution, principles, and application results related to a system for diagnosing main transformers in power plants via the radiofrequency method. The subject of the diagnostics is the occurrence ...
  • Testing an Impedance Non-destructive Method to Evaluate Steel-Fiber Concrete Samples 

    Komárková, Tereza; Fiala, Pavel; Steinbauer, Miloslav; Roubal, Zdeněk (DE GRUYTER POLAND SP ZOO, 2018-03-01)
    Steel-fiber reinforced concrete is a composite material characterized by outstanding tensile properties and resistance to the development of cracks. The concrete, however, exhibits such characteristics only on the condition ...
