    • AN ANALYSIS OF SPATIAL STRUCTURE OF URBAN REGIONAL NETWORKS USING GIS 

      Author: Kostin , Vitalii; Halounová , Lena
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Road network is the foundation of the urbanization process. Initially, it represented an indispensable part not only for the very existence of cities but also for their further economic and social development. Gradually ...
    • PARTICULARS OF ADSORBENT REGENERATION WITH THE USE OF MICROWAVE ENERGY 

      Author: Dobrotvorskiy , Sergey; Dobrovolska , Ludmila; Basova , Yevheniia; Aleksenko , Borys
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Energy conservation issues are acute in the world. Compressed air is widely used in the modern industrial production. The production of compressed air is a very energy-intensive process, since most of the energy, which is ...
    • LOW LEAKAGE CHARGE RECYCLING TECHNIQUE FOR POWER MINIMIZATION IN CNTFET CIRCUITS 

      Author: Kavitha , Manickam; Kalpana M., Alagar
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Carbon Nanotube Field Effect Transistor (CNTFET) is one of the most promising candidates in the near future for digital design due to its better electrostatics and higher mobility characteristics. Parameters that determine ...
    • EVALUATION OF RAILWAY BALLAST LAYER CONSOLIDATION AFTER MAINTENANCE WORKS 

      Author: Sysyn , Mykola; Nabochenko , Olga; Kovalchuk , Vitalii; Gerber , Ulf
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      The results of the study of the ballast layer consolidation after the work of ballast-tamping machines of different types are given in the article. The existing methods of determining the degree of consolidation of the ...
    • OPTIMIZATION OF BIODIESEL PRODUCTION FROM WASTE FRYING OIL OVER ALUMINA SUPPORTED CHICKEN EGGSHELL CATALYST USING EXPERIMENTAL DESIGN TOOL 

      Author: Yusuff S., Adeyinka; Popoola T., Lekan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      An optimization of the biodiesel production from a waste frying oil via a heterogeneous transesterification was studied. This present study is also aimed at investigating the catalytic ehaviour of the alumina supported ...
    • PARTICLE MOTION OVER THE EDGE OF AN INCLINED PLANE THAT PERFORMS AXIAL MOVEMENT IN A VERTICAL LIMITING CYLINDER 

      Author: Pylypaka F., Serhii; Klendii B., Mykola; Nesvidomin M., Viktor; Trokhaniak I., Viktor
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Differential equations of a relative material particle motion over the edge of an inclined flat ellipse that rotates around the axis of a vertical limiting cylinder have been deduced. The position of a plane relative to ...
    • THE SUGGESTIONS AS TO THE CALCULATION BEARING CAPACITY OF SANDWICH REINFORCED CONCRETE — FOAMED CONCRETE FLOOR SLABS 

      Author: Lytvyniak , Oksana; Tashak , Myroslava
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      This article presents the results of an experimental research of sandwich reinforced concrete-foamed concrete floor slabs. These floor slabs combine three different materials — normal concrete, foamed concrete and a steel ...
    • MATHEMATICAL ALGORITHM OF FUZZY LOGIC CONTROLLER FOR MULTILEVEL INVERTER CREATING VERTICAL DIVIDED VOLTAGE 

      Author: Can , Erol
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      A 9-level inverter with a boost converter has been controlled with a fuzzy logic controller and a PID controller for regulating output voltage applications on resistive (R) and inductive (L), capacitance (C). The mathematical ...
    • WELDING OF NITINOL BY SELECTED TECHNOLOGIES 

      Author: Kramár , Tomáš; Tauer , Jan; Vondrouš , Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Nitinol is a perspective alloy that is difficult to weld because of its high sensitivity to heat, atmospheric gases and the NiTi phase instability. We evaluated several welding techniques with regard to their applicability ...
    • MODELLING SIMULATION AND PARAMETER IDENTIFICATION OF ACTIVE POLLUTION REDUCTION WITH PHOTOCATALYTIC ASPHALT 

      Author: Kruschwitz , Jens; Lind , Martin; Muntean , Adrian; Richardson , Omar; Wondmagegne , Yosief
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      We develop and implement a numerical model to simulate the effect of photocatalytic asphalt on reducing the concentration of nitrogen monoxide (NO) due to the presence of heavy traffic in an urban environment. The contributions ...
