    • A QUANTITATIVE EVALUATION OF THE WATER DISTRIBUTION IN A SOIL SAMPLE USING NEUTRON IMAGING 

      Autor: Šácha , Jan; Sněhota , Michal; Hovind , Jan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      This paper presents an empirical method by Kang et al. recently proposed for correcting two-dimensional neutron radiography for water quantification in soil. The method was tested on data from neutron imaging of the water ...

    • BACK TO BASICS: TOWARDS NOVEL COMPUTATION AND ARRANGEMENT OF SPATIAL SENSORY IN IMAGES 

      Autor: Wen , Wei; Khatibi , Siamak
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      The current camera has made a huge progress in the sensor resolution and the lowluminance performance. However, we are still far from having an optimal camera as powerful as our eye is. The study of the evolution process ...

    • IMPACT OF PLASTIC DEFORMATION ON THE PROPERTIES OF A SELECTED ALUMINIUM ALLOY 

      Autor: Lišková , Anna; Lacková , Petra; Mihaliková , Mária; Kočiško , Róbert
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      This paper reports on an experiment to assess the influence of plastic deformation on the microstructure and properties of EN AW 6012 (AlMgSiPb) aluminium alloy in two states. The first was the initial state with heat ...

    • EXPERIMENTAL EVALUATION OF WEDM MACHINED SURFACE WAVINESS 

      Autor: Mouralova , Katerina; Kovar , Jiri; Houska , Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      Wire Electrical Discharge Machining (WEDM) an unconventional machining technology which has become indispensable in many industries. The typical morphology of a surface machined using the electrical discharge technology ...

    • ANALYSIS OF INTENSIVELY BLASTED ELECTRIC ARC BURNING IN THE ARC HEATER'S ANODE CHANNEL 

      Autor: Senk , Josef; Jakubova , Ivana; Laznickova , Ilona
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      The paper deals with the description of the intensively blasted electric arc burning in Ar in the anode channel of the arc heater operated under various conditions. Directly measured experimental data (current, voltage, ...

    • AN EXPERIMENTAL ASSESSMENT OF THE PLATE HEAT EXCHANGER CHARACTERISTICS BY WILSON PLOT METHOD 

      Autor: Opatřil , Jan; Havlík , Jan; Bartoš , Ondřej; Dlouhý , Tomáš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      An aim of this paper is suggestion of the evaluation method based on the experimental data and the Wilson plot method for the Plate Heat Exchangers (PHE). For the purpose of the project the new experimental loop was built ...

    • A METHOD FOR MEASURING THE SENSITIVITY OF BUILDING STRUCTURAL MEMBERS TO FIRE DECAY PHASES 

      Autor: Gernay , Thomas
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      Firefighters face a major threat when intervening in a building during a fire: the possibility of structural collapse during the cooling phase of the fire, or soon thereafter. At present, this threat is amplified by the ...

    • OPTIMALIZATION OF AFTERBURNER CHANNEL IN BIOMASS BOILER USING CFD ANALYSIS 

      Autor: Pospíšil , Jiří; Lisý , Martin; Špiláček , Michal
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
