    • MECHANICAL MODEL FOR HUMAN BALANCING ON ROLLING BALANCE BOARD 

      Autor: Molnar, Csenge A.; Zelei, Ambrus; Insperger, Tamas
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      A two-degree-of-freedom mechanical model was developed to analyze human balancing on rolling balance board in the frontal plane. The human nervous system is modeled as a proportionalderivative controller with constant ...

    • MODELLING AND SIMULATION OF LATTICE STRUCTURES USING VARIOUS MATERIAL MODELS FOR POLYMERIC MATERIALS 

      Autor: Lehner, Kerstin; Kalteis, Anna; Major, Zoltan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      Based on lightweight design concepts, lattices are increasingly considered as internal structures. This work deals with the simulation of periodically constructed lattices to characterize their behaviour under different ...

    • MODELLING AND SIMULATION OF ROCKING SUITCASES 

      Autor: Horvath, Hanna Zsofia; Takacs, Denes
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      The rocking motion of two-wheeled suitcases is investigated. A rigid body mechanical model of the suitcase is constructed. All of the possible motion states (both wheels on the ground, one wheel on the ground, none of the ...

    • MULTI-CHANNEL CONTROL SYSTEM FOR IN-SITU LABORATORY LOADING DEVICES 

      Autor: Rada, Václav; Fíla, Tomáš; Zlámal, Petr; Kytýř, Daniel; Koudelka, Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      In recent years, open-source applications have replaced proprietary software in many fields. Especially open-source software tools based on Linux operating system have wide range of utilization. In terms of CNC solutions, ...

    • NUMERICAL MODELLING OF COMPRESSIVE CHARACTERISTICS OF AUXETIC STRUCTURES 

      Autor: Neuhäuserová, Michaela; Koudelka, Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      The paper is focused on numerical analysis of mechanical behaviour of auxetic structures with re-entrant tetrakaidecahedral unit cell subjected to uni-axial quasi-static compression. The mechanical behaviour was evaluated ...

    • OPTIMIZATION OF DECOMPRESSIVE CRANIECTOMY BASED ON FINITE ELEMENT SIMULATIONS 

      Autor: Hazay, Mate; Bakos, Bernadett; Toth, Peter Jozsef; Buki, Andras; Bojtar, Imre
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      Decompressive Craniectomy (DC) is a neurosurgical procedure which is often applied to decrease the intracranial pressure (ICP), even if its optimal execution in terms of the size and location of the skull opening is not ...

    • PREPROCESSING OF HOPKINSON BAR EXPERIMENT DATA: FILTER ANALYSIS 

      Autor: Adorna, Marcel; Falta, Jan; Fíla, Tomáš; Zlámal, Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      This work presents a data preprocessing procedure for signal acquired during high strain-rate loading using a custom Split Hopkinson Pressure Bar (SHPB). Before the evaluation of the experimental data, preprocessing of the ...

    • TESTING OF HYBRID NICKEL-POLYURETHANE FOAMS AT HIGH STRAIN-RATES USING HOPKINSON BAR AND DIGITAL IMAGE CORRELATION 

      Autor: Adorna, Marcel; Zlámal, Petr; Fíla, Tomáš; Falta, Jan; Felten, Markus; Fries, Michael; Jung, Anne
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      In this paper Split Hopkinson pressure bar (SHPB) was used for dynamic testing of nickel coated polyurethane hybrid foams. The foams were manufactured by electrodeposition of a nickel coating on the standard open-cell ...

    • UTILIZATION OF IMAGE AND SIGNAL PROCESSING TECHNIQUES FOR ASSESSMENT OF BUILT HERITAGE CONDITION 

      Autor: Koudelka, Petr; Koudelková, Veronika; Doktor, Tomáš; Kumpová, Ivana; Kytýř, Daniel; Valach, Jaroslav
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      Historical buildings represent invaluable heritage from the past and therefore their protection is a very important task. Assessment of their condition must not cause damage accumulation, thus the least possible volume ...
