    • EFFECTIVE FRACTURE ENERGY OF ULTRA-HIGH-PERFORMANCE FIBRE-REINFORCED CONCRETE UNDER INCREASED STRAIN RATES 

      Autor: Sovják , Radoslav; Rašínová , Jana; Máca , Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      The main objective of this paper is to contribute to the development of ultra-high performance fibre reinforced concrete (UHPFRC) with respect to its effective fracture energy. Effective fracture energy was investigated ...

    • HYDRATION OF PLASMA-TREATED ALUMOSILICATE BINDERS 

      Autor: Šmilauer , Vít; Babchenko , Oleg; Potocký , Štepán; Kromka , Alexander
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      Plasma treatment offers several applications in material science. In this research, the potential of plasma treatment is explored on the hydration of hydrophilic CNT-enriched cement and hydrophilic fly ash. The evolution ...

    • IMPROVING SPECIFIC POWER CONSUMPTION FOR MECHANICAL MIXING OF THE FEEDSTOCK IN A BIOGAS FERMENTER BY MECHANICAL DISINTEGRATION OF LIGNOCELLULOSE BIOMASS 

      Autor: Kratky , Lukas; Jirout , Tomáš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      Lignocellulosic biomass particles in biogas fermenter batch either sediment towards vessel bottom or rise towards batch surface, where they float and form a compact thick scum. These processes have primarily the negative ...

    • RESONANT SWITCH MODEL OF HF QPOS AND EQUATIONS OF STATE OF NEUTRON STARS AND QUARK STARS 

      Autor: Stuchlík , Zdenek; Urbanec , Martin; Kotrlová , Andrea; Török , Gabriel; Goluchová , Katerina
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      The mass and spin estimates of the 4U 1636−53 neutron star obtained by the Resonant Switch (RS) model of high-frequency quasi-periodic oscillations (HF QPOs) are tested by a large variety of equations of state (EoS) governing ...

    • STRUCTURING OF DIAMOND FILMS USING MICROSPHERE LITHOGRAPHY 

      Autor: Domonkos , Mária; Ižák , Tibor; Štolcová , Lucie; Proška , Jan; Demo , Pavel; Kromka , Alexander
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      In this study, the structuring of micro- and nanocrystalline diamond thin films is demonstrated. The structuring of the diamond films is performed using the technique of microsphere lithography followed by reactive ion ...

    • TOWARDS EVOLUTIONARY DESIGN OF COMPLEX SYSTEMS INSPIRED BY NATURE 

      Autor: Vítku , Jaroslav; Nahodil , Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      This paper presents first steps towards evolutionary design of complex autonomous systems. The approach is inspired in modularity of human brain and principles of evolution. Rather than evolving neural networks or neural-based ...
