    • INDICATORS FOR COMMON CROSSING STRUCTURAL HEALTH MONITORING WITH TRACKSIDE INERTIAL MEASUREMENTS 

      Autor: Sysyn , Mykola; Gerber , Ulf; Nabochenko , Olga; Li , Yangyang; Kovalchuk , Vitalii
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      This paper focuses on the experimental study of an alteration in the railway crossing dynamic response due to the rolling surface degradation during a crossing’s lifecycle. The maximal acceleration measured with the ...
    • ADSORPTION OF CATIONIC DYE FROM AQUEOUS SOLUTION USING COMPOSITE CHICKEN EGGSHELL ANTHILL CLAY: OPTIMIZATION OF ADSORBENT PREPARATION CONDITIONS 

      Autor: Yusuff Sikiru, Adeyinka
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      A composite adsorbent was prepared from anthill and eggshell mixture, using an incipient wetness impregnation method and it was used for an adsorption of cationic dye (methylene blue, MB) from an aqueous solution. The ...
    • A STUDY OF FERROFLUID LUBRICATION BASED ROUGH SINE FILM SLIDER BEARING WITH ASSORTED POROUS STRUCTURE 

      Autor: Munshi M., Mohmmadraiyan; Patel R., Ashok; Deheri B., Gunamani
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      This paper attempts to study a ferrofluid lubrication based rough sine film slider bearing with assorted porous structure using a numerical approach. The fluid flow of the system is regulated by the Neuringer-Rosensweig ...
    • GENERAL CALCULATION OF WINDING FACTOR FOR MULTIPHASE/LAYER ELECTRICAL MACHINES IRRESPECTIVE OF POLES NUMBER 

      Autor: Ouamara , Daoud; Dubas , Frédéric; Randi Ali, Sid; Benallal Nadjib, Mohamed; Espanet , Christophe
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      In this paper, a method to calculate the winding factor by only considering stator parameters without the rotor ones is developed. This is interesting because it allows the separation of the stator and rotor design, unlike ...
    • DETERMINATION OF DETONABLE GAS MIXTURE HEAT FLUXES AT THERMAL DEBURRING 

      Autor: Plankovskyy , Sergey; Teodorczyk , Andrzei; Shypul , Olga; Tryfonov , Oleg; Brega , Dmytro
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Modern technology requires a multitude of precise parts that are a necessity in reliable methods of surface finishing. Energy of detonable gas mixture combustion has been used in manufacturing as a processing source for a ...
    • COMPARISON OF ENERGY FLOW STREAM AND ISENTROPIC METHOD FOR STEAM TURBINE ENERGY ANALYSIS 

      Autor: Blažević , Sebastijan; Mrzljak , Vedran; Anđelić , Nikola; Car , Zlatan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      In this paper, a comparison of two different methods for a steam turbine energy analysis is presented. A high-pressure steam turbine from a supercritical thermal power plant (HPT) was analysed at three different turbine ...
    • SOLAR ABSORBER WITH A STRUCTURED SURFACE – A WAY TO INCREASE EFFICIENCY 

      Autor: Mrňa , Libor; Řiháček , Jan; Šarbort , Martin; Horník , Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      The basic idea of a solar absorber’s thermal gain increase is the keyhole effect utilization during which the radiation is absorbed by multiple reflections on cavity walls. The lattice of pyramidal or conical cavities on ...
    • SIMULATION OF LOWGRADE COAL COMBUSTION IN REAL CHAMBERS OF ENERGY OBJECTS 

      Autor: Askarova , Aliya; Bolegenova , Saltanat; Bolegenova , Symbat; Beketayeva , Meruyert; Maximov , Valeriy; Nugymanova , Aizhan; Šafařík , Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      The aim of the work is to create new computer technologies for 3D modelling of heat and mass transfer processes in high-temperature physicochemically reacting environments that will allow to determine the aerodynamics of ...
