    • REDUCTION OF UNCERTAINTIES IN LASER STRIPE MEASUREMENT OF SOLID PARTICLES CONCENTRATION 

      Autor: Krupička , Jan; Picek , Tomáš; Zrostlík , Štěpán
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      Laser stripe measurement (LSM) is a relatively novel method for measuring a local concentration of coarse particles in a mixture with fluid. It is based on an analysis of camera records of the laser sheet penetration in ...

    • THE EFFECT OF DIFFERENT FORMS OF OXYGEN ON PROPERTIES OF BETA TITANIUM ALLOYS 

      Autor: Málek , Jaroslav; Hnilica , František; Bartáková , Sonia; Míka , Patrik; Veselý , Jaroslav
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      The beta-titanium alloys are widely used in many applications (medicine, aerospace industry etc.) due to their superior properties, such as corrosion resistance, biocompatibility and high strength to weight ratio. One of ...

    • AUTOMATIC CLASSIFICATION OF POINT CLOUDS FOR HIGHWAY DOCUMENTATION 

      Autor: Hůlková , Martina; Pavelka , Karel; Matoušková , Eva
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      Mobile laser scanning systems confirmed the capability for detailed roadway documentation. Hand in hand with enormous datasets acquired by these systems is the increase in the demands on the fast and effective processing ...

    • APPLICATION OF CORROSION PLATES IN DRINKING WATER 

      Autor: Skalický , Michal
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      Drinking water has always been, is and will be a strategic raw material. Stopping corrosion or at least minimisation of its impact while keeping quality drinking water supplies is a big challenge for the future. That is ...

    • HYDROPHOBIC IMPREGNATION OF GEOPOLYMER COMPOSITE BY ETHOXYSILANES 

      Autor: Mašek , Zdeněk; Diblikova , Linda
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      A geopolymer composite was impregnated by incorporating the hydrophobic alkyl group on the outer surface and in the inner structure of the geopolymer. Ethoxysilanes 1H,1H,2H,2H perfluoroctyltriethoxysilane and hexadecylt ...

    • PRIMARY PEAK RATIO CORRELATION TO THE MEASUREMENT ACCURACY OF PIV METHOD 

      Autor: Novotny , Jan; Machovska , Ilona
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      An estimation of a measurement accuracy at each measured point is crucial regarding the applicability of results of the measurements. The aim of this work is to determine the correlation between individual metrics and the ...

    • CHARACTERIZATION OF RECYCLED LINEAR DENSITY POLYETHYLENE/IMPERATA CYLINDRICA PARTICULATE COMPOSITES 

      Autor: Olusunmade Femi, Olusola; Zechariah , Sunday; Yusuf Ayotunde, Taofeek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      Water-sachets made from low density polyethylene (LDPE) form a bulk of plastic wastes which creates environmental challenges, while certain species of plants like Imperata cylindrica constitute large portion of weeds on ...

    • PARTICLE MOTION ON THE SURFACE OF A CONCAVE SOIL-TILLING DISK 

      Autor: Pylypaka , Serhii; Klendii , Mykola; Klendii , Oleksandra
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      Relative particle motion on the internal rough surface of a concave soil-tilling disk, which rotates around horizontal axis under a soil reaction force, has been considered. A disk blade is positioned in a vertical plane, ...

    • Editorial: FAREWELL AND WELCOME NEW EDITOR-IN-CHIEF 

      Autor: Adlerová , Iva
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      My seven years with Acta Polytechnica ended on June 30. The opportunity to lead this journal from a local list of reviewed periodicals to the prestigious databases – Web of Science, Scopus, Inspec, CAS and more – was a ...
