    • AERODYNAMIC LOAD OF AN AIRCRAFT WITH A HIGHLY ELASTIC WING 

      Autor: Schoř , Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      In this article, a method for calculation of air loads of an aircraft with an elastic wing is presented. The method can predict a redistribution of air loads when the elastic wing deforms. Unlike the traditional Euler or ...

    • CHARACTERIZATION OF SELECTED PROPERTIES OF COMPOSITES OF WASTE PAPER WITH UNTREATED BAMBOO STEM FIBRE AND RICE HUSK 

      Autor: Yusuf Ayotunde, Taofeek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      Composite technology is an excellent approach to utilizing natural fibres and agricultural wastes, which constitute an environmental nuisance. Efforts are being made to characterize the properties of composites produced ...

    • DESIGN OF PARTICULATE MATERIAL COMPACTOR ROLLS DIAMETER 

      Autor: Peciar , Peter; Macho , Oliver; Eckert , Maroš; Fekete , Roman; Kotora , Peter; Juriga , Martin; Kabát , Juraj; Gabrišová , Ľudmila; Peciar , Marián
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      At present, in a period of an industrial expansion great emphasis is placed on the environment. That means aiming for a reduced energy consumption, and also lessening dustiness from very fine powder material. This category ...

    • FICTITIOUS DOMAIN METHOD FOR NUMERICAL SIMULATION OF INCOMPRESSIBLE VISCOUS FLOW AROUND RIGID BODIES 

      Autor: Beno , Matej; Patzák , Bořek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      This article describes the method of efficient simulation of the flow around potentially many rigid obstacles. The finite element implementation is based on the incompressible Navier-Stokes equations using structured, ...

    • IMPROVEMENT OF ENERGY CONSUMPTION IN SPECTRUM SENSING COGNITIVE RADIO NETWORKS USING AN EFFICIENT TWO STAGE SENSING METHOD 

      Autor: Abdullah Najem, Hikmat; Abed Sami, Hadeel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      Cognitive radio (CR) is a wireless technology developed to improve the usage in the spectrum frequency. Energy consumption is considered as a big problem in this technology, especially during a spectrum sensing. In this ...
