    • Neural network based patient recovery estimation of a PAM-based rehabilitation robot 

      Autor: Dinh, Van-Vuong; Trinh, Minh-Chien; Bui, Tien-Dat; Duong, Minh-Duc; Dao, Quy-Thinh
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      Rehabilitation robots have shown a promise in aiding patient recovery by supporting them in repetitive, systematic training sessions. A critical factor in the success of such training is the patient’s recovery progress, ...

    • Improving the energy efficiency of a tram’s running gear 

      Autor: Semenov, Stanislav; Mikhailov, Evgeny; Kliuiev, Sergii; Dižo, Ján; Blatnický, Miroslav; Ishchuk, Vadym
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      This research analyses the influence of some design features of an undercarriage of a tram on the energy efficiency in terms of mechanical energy losses during its operation. The work includes the comparison of results of ...

    • From positional representation of numbers to positional representation of vectors 

      Autor: Farkas, Izabella Ingrid; Pelantová, Edita; Svobodová, Milena
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      To represent real m-dimensional vectors, a positional vector system given by a non-singular matrix M ∈ ℤm×m and a digit set Ɗ ⊂ ℤm is used. If m = 1, the system coincides with the well known numeration system used to ...

    • Qualitative sign stability of linear time invariant descriptor systems 

      Autor: Chand, Madhusmita; Paitandi, Mamoni; Gupta, Mahendra Kumar
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      This article discusses assessing the instability of a continuous linear homogeneous timeinvariant descriptor system. Some necessary conditions and sufficient conditions are derived to establish the stability of a matrix ...

    • Fractional multi-loop active disturbance rejection control for a lower knee exoskeleton system 

      Autor: Al-Awad, Nasir Ahmed; Humaidi, Amjad Jaleel; Al-Araji, Ahmed Sabah
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      Rehabilitation Exoskeleton is becoming more and more important in physiotherapists’ routine work. To improve the treatment performance, such as reducing the recovery period and/or monitoring and reacting to unpredictable ...

    • A comparative experimental investigation of high-temperature effect on fibre concrete and high strength concrete using UT and CM methods 

      Autor: Royaei, Javad; Sadeghi, Kabir; Nouban, Fatemeh
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      In this paper, a 28-day compressive strength test has been performed on samples including normal fibre concrete and high-strength concrete. The ultrasonic test (UT) as a non-destructive and compression machine (CM) as a ...

    • Mechanical and physical properties of cement mixtures for 3D processing 

      Autor: Litoš, Jiří; Šána, Vladimír; Uhlík, Adam; Kolář, Karel; Nguyen, Markéta
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      In this paper, information about cementitious composite materials for further 3D processing is discussed and supplemented. Many of the research in this area focuses primarily on cement composites suitable for 3D printing. ...
