    • A CONCEPTUAL STUDY OF A LIQUID METAL ALLOY IN A DISK-SHAPED MAGNETOHYDRODYNAMICS CONVERSION SYSTEM 

      Autor: Ayeleso, Ayokunle O.; Raji, Atanda K.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      The use of solar-heated liquid metal in a magnetohydrodynamics (MHD) generator provides an alternative and direct conversion method for electric power generation. This prompted the present study to conduct a three-dimensional ...

    • ADAPTIVE WAVELETS SLIDING MODE CONTROL FOR A CLASS OF SECOND ORDER UNDERACTUATED MECHANICAL SYSTEMS 

      Autor: Nafa, Fares; Boudouda, Aimad; Smaani, Billel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      The control of underactuated mechanical systems (UMS) remains an attracting field where researchers can develop their control algorithms. To this date, various linear and nonlinear control techniques using classical and ...

    • COUNTER-ROTATING DUAL ROTOR WIND TURBINE LAYOUT OPTIMISATION 

      Autor: Hetyei, Csaba; Szlivka, Ferenc
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      General energy demand is continuously increasing, thus the energy generating assets need to be optimised for higher efficiency. Wind turbines are no exception. Their maximum efficiency can be determined on a theoretical ...

    • DEPENDENCE OF THE VISCOSITY COEFFICIENT OF THE NIOSOMAL DISPERSION ON THE TEMPERATURE AND PARTICLE SIZE OF THE DISPERSED PHASE 

      Autor: Diskaeva, Elena Igorevna; Vecher, Olga Vladimirovna; Bazikov, Igor Alexandrovich; Elbekyan, Karine Sergeevna; Diskaeva, Elena Nikolaevna
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      The aim of this study was to experimentally investigate the dependence of viscosity coefficient of niosomal dispersion based on PEG-12 Dimethicone on the temperature and size of niosomes vesicles. The experiments were ...

    • MODIFIED POSSIBILISTIC FUZZY C-MEANS ALGORITHM FOR CLUSTERING INCOMPLETE DATA SETS 

      Autor: Rustam; Usman, Koredianto; Kamaruddin, Mudyawati; Chamidah, Dina; Nopendri; Saleh, Khaerudin; Eliskar, Yulinda; Marzuki, Ismail
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      A possibilistic fuzzy c-means (PFCM) algorithm is a reliable algorithm proposed to deal with the weaknesses associated with handling noise sensitivity and coincidence clusters in fuzzy c-means (FCM) and possibilistic c-means ...

    • NON-LINEAR ANALYSIS OF SLENDER MASONRY COLUMN SUBJECTED TO BIAXIAL BENDING 

      Autor: Vokál, Marek; Drahorád, Michal
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      The article deals with a method for analysing slender masonry columns. The proposed method uses material and geometric non-linearity. Various stress-strain diagrams can be used: linear, linear-plastic, parabolic-plastic, ...

    • PARALLEL MACHINE SCHEDULING WITH MONTE CARLO TREE SEARCH 

      Autor: Agárdi, Anita; Nehéz, Károly
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      In this article, a specific production scheduling problem (PSP), the Parallel Machine Scheduling Problem (PMSP) with Job and Machine Sequence Setup Times, Due Dates and Maintenance Times is presented. In this article after ...

    • SIMULATION OF A MANEUVERING AIRCRAFT USING A PANEL METHOD 

      Autor: Schoř, Pavel; Kouřil, Martin; Daněk, Vladimír
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      We present a method for numerical simulations of a maneuvering aircraft, which uses a first-order unsteady panel method as the only source of aerodynamic forces and moments. By using the proposed method, it is possible to ...

    • STRATEGIC MODULATION OF THERMAL TO ELECTRICAL ENERGY RATIO PRODUCED FROM PV/T MODULE 

      Autor: Aminou Moussavou, Anges A.; Raji, Atanda K.; Adonis, Marco
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      Several strategies have been developed to enhance the performance of a solar photovoltaicthermal (PV/T) system in buildings. However, these systems are limited by the cost, complex structure and power consumed by the pump. ...
