    • BETA CANTOR SERIES EXPANSION AND ADMISSIBLE SEQUENCES 

      Autor: Caalim , Jonathan; Demegillo , Shiela
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      We introduce a numeration system, called the beta Cantor series expansion, that generalizes the classical positive and negative beta expansions by allowing non-integer bases in the Q-Cantor series expansion. In particular, ...

    • OPTIMIZATION OF A SMALL SOLAR CHIMNEY 

      Autor: Castro Silva , Janaina Oliveira; Maia , Cristiana Brasil
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      An optimization study to maximize the exergy efficiency of a small-scale solar chimney was carried out. Optimization variables include collector diameter (Dc), collector height (Hc), tower height (Ht), and tower diameter ...

    • TESTING THE SUITABILITY OF THE EXTRUDED POLYSTYRENE (STYRODUR) APPLICATION IN THE TRACK SUBSTRUCTURE 

      Autor: Ižvolt , Libor; Dobeš , Peter; Mečár , Martin
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      Extruded polystyrene (XPS) and its excellent thermal insulation properties have been known for over 60 years. Due to its thermal, mechanical, but also deformation properties, XPS has a universal application, not only in ...

    • MINIMIZATION OF TOXIC EMISSIONS DURING BURNING LOW-GRADE FUEL AT KAZAKHSTAN THERMAL POWER PLANT 

      Autor: Askarova , Aliya; Šafařík , Pavel; Nugymanova , Aizhan; Bolegenova , Saltanat; Maximov , Valeriy; Bolegenova , Symbat
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      This paper presents new results of computational experiments on the implementation of Overfire Air (OFA) technologies using an example of a combustion chamber of the BKZ-75 boiler of the Shakhtinskaya power plant (Shakhtinsk, ...

    • MICROSTRUCTURAL CHARACTERISTICS, MECHANICAL AND WEAR BEHAVIOUR OF ALUMINIUM-ALLOYED DUCTILE IRONS SUBJECTED TO TWO AUSTEMPERING PROCESSES 

      Autor: Adebayo , Abdullahi Olawale; Oyetunji , Akinlabi; Alaneme , Kenneth Kenayo
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      The effect of aluminium addition and austempering processes on the microstructures, mechanical and wear properties of rotary melting furnace processed ductile irons was investigated. Ductile irons containing 1−4 wt.% Al ...

    • KINEMATIC SYNTHESIS OF CENTRAL-LEVER STEERING MECHANISM FOR FOUR WHEEL VEHICLES 

      Autor: Pramanik , Santiranjan; Thipse , Sukrut Shrikant
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      A central lever steering mechanism has been synthesized to obtain five precision points for a four-wheel vehicle using Hooke and Jeeves optimization method. This compound mechanism has been studied as two identical crossed ...

    • MODEL REFERENCE ADAPTIVE CONTROL-BASED GENETIC ALGORITHM DESIGN FOR HEADING SHIP MOTION 

      Autor: Al-Awad , Nasir Ahmad
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      In this paper, the heading control of a large ship is enhanced with a specific end goal, to check the unwanted impact of the waves on the actuator framework. The Nomoto model is investigated to describe the ship’s guiding ...

    • ON THE SECOND LIGHT FLASH EMITTED FROM A SPARK-GENERATED BUBBLE OSCILLATING IN WATER 

      Autor: Vokurka , Karel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      The light emitted from the spark-generated bubbles oscillating in water is studied experimentally. Attention is paid to the emission of light from bubbles in the final stages of their first contraction and in the early ...

    • THE CONDENSATION OF WATER VAPOUR IN A MIXTURE CONTAINING A HIGH CONCENTRATION OF NON-CONDENSABLE GAS IN A VERTICAL TUBE 

      Autor: Havlík , Jan; Dlouhý , Tomáš; Krempaský , Jakub
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      This paper deals with the condensation of water vapour possessing a content of noncondensable gas in vertical tubes. The condensation of pure steam on a vertical surface is introduced by the Nusselt condensation model. ...

    • NEURINGER-ROSEINWEIG MODEL BASED LONGITUDINALLY ROUGH POROUS CIRCULAR STEPPED PLATES IN THE EXISTENCE OF COUPLE STRESS 

      Autor: Vashi , Yoginibahen Devendrasinh; Patel , Rakesh Manilal; Deheri , Gunamani Biswanath
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      This study intents to scrutinize the impact of ferrofluid in the presence of couple stress for longitudinally rough porous circular stepped plates. The influence of longitudinal surface roughness is developed using the ...
