  • Sensitivity investigation to formaldehyde of the vapors of nanostructured films from ZnO semiconductor oxides for medical application 
    LUPAN, Oleg; POCAZNOI, Ion; ABABII, Nicolai; CRETU, Vasilii; SECU, Iuliana (Tehnica UTM, 2019)
    Formaldehyde (СH2О) of 40% is widely used in medicine as a substance applied in processes for sterilization of bone grafts for further use as implants. The efficiency of sterilization depends on the amount of СH2О remaining ...
  • Stochastic optimal control of a two-dimensional dynamical system 
    LEFEBVRE, Mario (Tehnica UTM, 2019)
    In this paper, exact and explicit solutions will be found in particular cases by making use of the method of similarity solutions to solve the partial differential equation satisfied by the value function.
  • Synthesis of the auto-tuned pid controller to the inertial object 
    BALABANOV, Anatolii; IZVOREANU, Bartolomeu; POTLOG, Mihail; FIODOROV, Ion; COJUHARI, Irina; MORARU, Dumitru (Tehnica UTM, 2019)
    In the paper, it was developed the mechanism for adaptation of the transfer coefficient of PID controller to the model of object with inertia first order and time delay; schema for simulation of the control system with ...
  • Synthesis of the PID controller to the system with maximum stability degree based on the genetic algorithm 
    COJUHARI, Irina; IZVOREANU, Bartolomeu; FIODOROV, Ion; MORARU, Dumitru; LISNIC, Inga (Tehnica UTM, 2019)
    The control problem in the various industrial applications is one of the most important problem, on which depends the high performance of the automatic control system. At the automation of the industrial processes in a ...
  • The theory of inventive problem solving 
    MAFTEI, Vitalie (Tehnica UTM, 2019)
    A modern engineer should have a fairly serious set of system competencies. Today, in the qualification of an engineer, knowledge and skills in ensuring the relations of production with the market are valued, in the future ...
  • TiO2/ZnO columnar heterostructures 
    MAGARIU, Nicolae; PAUPORTÉ, Thierry; LUPAN, Oleg (Tehnica UTM, 2019)
    In this work we synthesized TiO2/ZnO columnar films and studied their characteristics, including the sensor structures based on zinc oxide doped with different impurities. The effects of nano-heterogeneous formation of ...
  • Tri-axial square helmholtz coil for testing satellite stabilization with magnetorquers
