    • Influence of carbonation on torrent air permeability of concrete 

      Autor: Jaskulski, Roman; Kubissa, Wojciech; Zapała, Dominika
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      Air permeability testing is increasingly being used to measure the impermeability of concrete and to estimate the durability of reinforced concrete structures using this property. This paper presents the results of a ...

    • Monitoring the internal structure behaviour of alkali-activated slag paste: effect of the curing mode 

      Autor: Nápravník, Petr; Kocáb, Dalibor; Bílek, Jr., Vlastimil; Lisztwan, Dominik; Kucharczyková, Barbara
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      This paper deals with the monitoring of the internal structure behaviour of an alkaliactivated slag (AAS) paste. The slag was activated with a 4M solution of sodium hydroxide. The behaviour of the internal structure of the ...

    • Prediction of temperature field distribution in a gas turbine using a higher order neural network 

      Autor: Pařez, Jan; Kovář, Patrik; Tater, Adam
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      This paper presents the prediction of temperature field distribution in a single annular section using an artificial neural network (ANN). This temperature distribution is non-uniform on the outer tube due to continuous ...

    • Semi-analytical approach-based studies of the squeeze film lubrication between rough porous annular discs: Rabinowitsch fluid model 

      Autor: Rahul, Amit Kumar; Singh, Manoj Kumar; Tiwari, Ravi; Paul, Sourabh; Rao, Pentyala Srinivasa; Biswas, Rohahn
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      In recent years, there has been much interest in the effects of porosity and surface roughness (SR) or geometric irregularities between two moving plates under hydrodynamic lubrication. Porous bearings are used extensively ...
