    • Genetic algorithms to determine the optimal parameters of an ensemble local mean decomposition 

      Author: Silva, Willian T. F. D.; Borges, Filipe D. D. M.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      An optimization method for an ensemble local mean decomposition (ELMD) parameters selection using genetic algorithms is proposed. The execution of this technique depends heavily on the correct choice of the parameters of ...
    • Improving the efficiency of a steam power plant cycle by integrating a rotary indirect dryer 

      Author: Sabatini, Michel; Havlík, Jan; Dlouhý, Tomáš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      This article deals with the integration of a rotary indirect dryer, heated by low pressure extraction steam, into the Rankine cycle. The article evaluates the power generation efficiency of a steam power plant, with an ...
    • Marine diesel engines operating cycle simulation for diagnostics issues 

      Author: Minchev, Dmytro S.; Varbanets, Roman A.; Alexandrovskaya, Nadiya I.; Pisintsaly, Ludmila V.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      The ongoing monitoring of marine diesel engines helps to detect the deviations of its parameters early and prevent major failures. But the experimental diagnostics data are generally limited, so frequently, it isn’t possible ...
    • Post-impact mechanical characterization of HMPE yarns 

      Author: Belloni, Eduarda da Silva; Clain, Fernanda Mazuco; Guilherme, Carlos Eduardo Marcos
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      The present work evaluates the mechanical behaviour of High Modulus Polyethylene (HMPE) yarns after being impacted by sudden axial loads. The influence of loading conditions on the structural integrity of yarns is assessed ...
    • Self tunning filter for three levels four legs shunt active power filter with fuzzy logic controller 

      Author: Djendaoui, Dahmane; Benaissa, Amar; Rabhi, Boualaga; Zellouma, Laid
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      The low harmonic distortion and reduced switching losses are the advantages of using the multilevel inverter. For this purpose, the three-level inverter is used in this paper as a three-phase four-leg shunt active power ...
    • The impact of the air temperature on measuring the zenith angle during the year in the ground layer of the atmosphere for the needs of engineering surveying 

      Author: Suk, Tomáš; Štroner, Martin
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      This paper presents the results of over a year-long experiment dealing with a temperature measurement to calculate the theoretical effect of the atmosphere on the measured zenith angle in engineering surveying. The ...
