    PLĂMĂDEALĂ, Vasile; SLOBODEANIUC, Stanislav (Tehnica UTM, 2019)
    Unfortunately, most of the technologies applied and currently used by mankind, to a lesser or greater degree, negatively influence and lead to the degradation and degeneration of the planetary ecosystem, with rail transport ...
  • Performance modeling of network defense in breadth systems by matrix rewriting SRN with fuzzy parameters 
    GUŢULEAC, Emilian; ZAPOROJAN, Sergiu; MORARU, Victor; SCLIFOS, Alexei (Technical University of Moldova, 2019)
    We have defined in this paper, a new kind of stochastic reward network (SRN) by introducing matrix attributes and fuzzy parameters of timed transitions and of rewriting rules, called MFRSRN, allowing the dynamic marking-dependent ...
  • Quantum treatment of self-organization phenomena of excitons and biexcitons 
    CIOBANU, Nellu; ROTARU, Anatol; GONTIA, Ilarie; TRONCIU, Vasile (Technical University of Moldova, 2019)
    We present in this paper the quantum treatment of self-organization phenomena of excitons and biexcitons in the geometry of a ring cavity. Applying the adiabatic elimination method of the exciton and biexciton variables, ...
  • Quo vadis robotics? 
    BĂJENESCU, Titu-Marius I. (Technical University of Moldova, 2019)
    Robotics is an extremely dynamic field with thriving advancement in its technology. The capabilities of trusted robots will grow and evolve over time. Robots will be able to explain what they do and why. This will enable ...
