    • OPTIMIZING EFFICIENCY OF THE COMBINED SEWER OVERFLOW CHAMBER HOBAS 

      Autor: Procházka, Jiří; Pollert, Jaroslav
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      The paper deals with the design of swinging self-clean screen bars and the assessment of pressure losses in the combined sewer overflow chamber (HOBAS CSO Chamber), sold by the company HOBAS. The HOBAS CSO Chamber ensures ...

    • TESTING OF GLUED JOINTS ON PLASTIC PARTS MANUFACTURED USING FFF TECHNOLOGY 

      Autor: Suder , Jiří; Vocetka , Michal; Kot , Tomáš; Fojtík , František; Fusek , Martin
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      The article focuses on the testing of glued joints of plastic parts manufactured by 3D rapid prototyping, using the Fused Filament Fabrication technology. The first part of the article describes the suitability of using a ...

    • A combined strain element to functionally graded structures in thermal environment 

      Autor: Ton-That , Hoang Lan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      Functionally graded materials are commonly used in a thermal environment to change the properties of constituent materials. They inherently withstand high temperature gradients due to a low thermal conductivity, core ...

    • VERSATILE CHIRP SINE GENERATOR ON FIXED-POINT FPGA 

      Autor: Kunz, Jan; Beneš, Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      This paper deals with a logarithmic and a linear chirp sine generation on a fixed-point FPGA mainly for vibration testing, nevertheless, the generator can also be used in other areas. A basic overview of the logarithmic ...

    • A NEW FASTENER TO ENSURE THE RELIABILITY OF A PASSENGER CAR BODY ON A TRAIN FERRY 

      Autor: Lovska, Alyona; Fomin , Oleksij
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      To ensure the strength of the passenger car bodies during transportation on train ferries, it is proposed to mount fastening elements of chain binders on the body bolster beams. The principle of such an element is based ...

    • HEAT TRANSFER ENHANCEMENT AND FRICTION IN DOUBLE PIPE HEAT EXCHANGER WITH VARIOUS NUMBER OF LONGITUDINAL GROOVES 

      Autor: Sunu , Putu Wijaya; Anakottapary , Daud Simon; Suarta , I Made; Santosa , I Dewa Made Cipta; Suarsana , Ketut
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      It has been found out that heat exchangers with longitudinal grooves produce better heat transfer than those without longitudinal grooves. However, up to now, there have been few investigations and applications of longitudinal ...

    • Newmark algorithm for dynamic analysis with Maxwell chain model 

      Autor: Schmidt , Jaroslav; Janda , Tomáš; Zemanová , Alena; Zeman , Jan; Šejnoha , Michal
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      This paper investigates a time-stepping procedure of the Newmark type for dynamic analyses of viscoelastic structures characterized by a generalized Maxwell model. We depart from a scheme developed for a three-parameter ...

    • ANALYSES OF WASTE PRODUCTS OBTAINED BY LASER CUTTING OF AW-3103 ALUMINIUM ALLOY 

      Autor: Loskot , Jan; Zubko , Maciej; Janikowski , Zbigniew
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      In the presented research, the methods of scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction and transmission electron microscopy were applied to analyse the powder waste obtained by ...

    • THE DEVELOPMENT OF A NEW ADSORPTION-DESORPTION DEVICE 

      Autor: Gabrišová , Ľudmila; Peciar , Peter; Macho , Oliver; Juriga , Martin; Galbavá , Paulína; Nižnanská , Žofia; Kubinec , Róbert; Valent , Ivan; Peciar , Marián
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      The aim of this work was to construct a new adsorption-desorption device based on the principle of separation of volatile organic compounds, e.g., ethanol. As an adsorbent, it is possible to use granulated activated carbon ...

    • USING TEXTILE ARAMID FABRICS TO INCREASE THE BALLISTIC RESISTANCE OF ULTRA-HIGH-PERFORMANCE STEEL-FIBRE REINFORCED CONCRETE 

      Autor: Mára , Michal; Sovják , Radoslav; Fornůsek , Jindřich
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      Thin plates made of Ultra-High-Performance Steel-Fibre-Reinforced Concrete (UHPSFRC) with textile Aramid fabrics were subjected to a projectile impact and its post-test damage was discussed. The damage degrees were the ...
