    • TREATMENT OF NATURAL GAS BY ADSORPTION OF CO2 

      Autor: Hádková , Kristýna; Tekáč , Viktor; Ciahotný , Karel; Beňo , Zdeněk; Vrbová , Veronika
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Apart from burning, one of the possible uses of natural gas is as a fuel for motor vehicles. There are two types of fuel from natural gas — CNG (Compressed Natural Gas) or LNG (Liquefied Natural Gas). Liquefaction of natural ...

    • OPERATING SPECIFICATIONS OF CATALYTIC CLEANING OF GAS FROM BIOMASS GASIFICATION 

      Autor: Lisý , Martin; Baláš , Marek; Špiláček , Michal; Skála , Zdeněk
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      The paper focuses on the theoretical description of the cleaning of syngas from biomass and waste gasification using catalytic methods, and on the verification of the theory through experiments. The main obstruction to ...

    • ANALYTICAL METHODS FOR CALCULATING FAN AERODYNAMICS 

      Autor: Dostal , Jan; Kuzel , Jan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      This paper presents results obtained between 2010 and 2014 in the field of fan aerodynamics at the Department of Composite Technology at the VZLÚ aerospace research and experimental institute in Prague – Letnany. The need ...

    • AN INTERPOLATION METHOD FOR DETERMINING THE FREQUENCIES OF PARAMETERIZED LARGE-SCALE STRUCTURES 

      Autor: Nasisi , Salvatore; Valášek , Michael; Vampola , Tomáš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Parametric Model Order Reduction (pMOR) is an emerging category of models developed with the aim of describing reduced first and second-order dynamical systems. The use of a pROM turns out useful in a variety of applications ...

    • CALCULATION OF STRESS AND DEFORMATION IN FUEL ROD CLADDING DURING PELLET-CLADDING INTERACTION 

      Autor: Halabuk , Dávid; Martinec , Jiří
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      The elementary parts of every fuel assembly, and thus of the reactor core, are fuel rods. The main function of cladding is hermetic separation of nuclear fuel from coolant. The fuel rod works in very specific and difficult ...

    • A HARDWARE-IN-THE-LOOP SIMULATOR BASED ON REAL SKODA SUPERB VEHICLE AND RT-LAB/CARSIM 

      Autor: Biroš , Milan; Kyslan , Karol; Ďurovský , František
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      This paper describes the design and realization of a hardware-in-the-loop simulator made from a real Skoda Superb vehicle. A combination of RT-LAB and CarSim software is used for real-time control and for handling the ...

    • VERIFICATION OF CENSUS DEVICES IN TRANSPORTATION RESEARCH 

      Autor: Petrů, Jan; Kludka, Michal; Krivda, Vladislav; Mahdalova, Ivana; Zeman, Karel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      The article presents a comparison of three devices and two methods that are used to count traffic flow. All measurements were carried out at a roundabout in Ostrava, where the following devices were used: Viacount II, Icoms ...

    • MULTILAYER COATINGS Ti/TiN Cr/CrN AND W/WN DEPOSITED BY MAGNETRON SPUTTERING FOR IMPROVEMENT OF ADHESION TO BASE MATERIALS

      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      The paper deals with evaluation of single and multilayer layer PVD coatings based on Cr and Ti widely used in tool application. Additionally, W and WN based coating which are not so widespread were designed and deposited ...

    • FINITE ELEMENT ANALYSIS OF AORTAL BIFURCATION 

      Autor: Kronek , Jakub; Žitný , Rudolf
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Arterial bifurcations loaded by internal pressure represent significant stress concentrators. Increased mechanical stress inside arterial wall probably accelerates pathogenic processes at these places. Stress concentration ...
