    Sobola, Dinara; Ramazanov, Shihgasan; Konečný, Martin; Orudzhev, Farid; Kaspar, Pavel; Papež, Nikola; Knápek, Alexandr; Potoček, Michal (MDPI, 2020-05-23)
    The objective of this work is to study the delamination of bismuth ferrite prepared by atomic layer deposition on highly oriented pyrolytic graphite (HOPG) substrate. The samples’ structures and compositions are provided ...

  • Synthesis of high density sub-10 µm (Ba0.85Ca0.15) (Zr0.1Ti0.9)O3-xCeO2 lead-free ceramics using a twostep sintering technique 

    Bijalwan, Vijay; Tofel, Pavel (TAYLOR & FRANCIS LTD, 2019-10-29)
    (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3-xCeO2, (BCZTCe) lead-free piezoelectric ceramics were processed conventionally using a two-step sintering technique. The results suggest that two-step sintering is an effective technique to ...

  • The Effect of the Orientation Towards Analyte Flow on Electrochemical Sensor Performance and Current Fluctuations 

    Sedlák, Petr; Kuberský, Petr (MDPI, 2020-02-14)
    Analyte flow influences the performance of every gas sensor; thus, most of these sensors usually contain a diffusion barrier (layer, cover, inlet) that can prevent the negative impact of a sudden change of direction and/or ...

  • Numerically optimized band boundaries of Planck mean absorption coefficients in air plasma 

    Kloc, Petr; Aubrecht, Vladimír; Bartlová, Milada (IOP Publishing, 2017-08-02)
    Radiation heat transfer plays an important role in the energy balance of plasma in an electric arc and its accurate prediction is essential for the development of new electrical devices. Unfortunately, a very complex ...

  • Novel Algorithm in Activation Process of GPON Network 

    Horváth, Tomáš; Münster, Petr; Jurčík, Michal; Filka, Miloslav (Croatian Communications and Information Society, 2016-02-17)
    Passive optical networks are dominating access networks around the world due to its their economical aspect, bandwidth, and penetration. It is necessary to deal with specification of these networks.

  • P1-approximation for radiative transfer: application to SF6 + Cu arc plasmas 

    Bogatyreva, Nadezda; Bartlová, Milada; Aubrecht, Vladimír; Holcman, Vladimír (De Gruyter Open, 2014-12-01)
    The objective of the paper consists of a theoretical prediction of radiative heat transfer in arc plasmas of SF6 (sulphur hexafluoride) with various admixtures of copper vapours. As a mathematical tool the P1-approximation ...

  • Fractal Analysis of the 3-D surface Topography of GaAs Solar Cells 

    Talu, Stefan; Papež, Nikola; Sobola, Dinara; Tofel, Pavel (DEStech Publications, Inc., 2018-02-11)
    This article is devoted to study of Atomic Force Microscopy (AFM) images of solar cells based on gallium arsenide (GaAs). Mathematical processing of data involves obtaining additional information about topography. The ...

  • Visualization Tool for Control Signalling in NG-PON2 

    Horváth, Tomáš; Jurčík, Michal (Croatian Communications and Information Society, 2016-07-01)
    The requirements of end users on the quality of Internet connection and services is forcing the Internet providers and technical community to propose and introduce new technologies which may react to this demand. The most ...

  • Current-fluctuation measurements of amperometric gas sensors prepared by three different technology procedures 

    Sedlák, Petr; Kuberský, Petr; Škarvada, Pavel; Hamáček, Aleš; Sedláková, Vlasta; Majzner, Jiří; Nešpůrek, Stanislav; Šikula, Josef (Polish Academy of Sciences, 2016-12-13)
    The paper focuses on usage of noise measurement (electric current-fluctuation measurement) for evaluation of electrochemical sensors which were prepared by different fabrication processes: (i) lift-off and drop-casting ...
