    Investigation of the influence of generator signal higher order propagation components and ways of its compensating in the multiprobe microwave multimeter
    (2014) Miroshnik, M. A.; Kovalenko, M. A.; Zaichenko, O. B.
    The physical and mathematical and metrological model of higher order propagation modes in multiprobe microwave multimeter with three sensors was composed. The higher order propagation modes error estimation, which is proposed, minimizes error by shifting sensors from the middle of the waveguide broad wall to the periphery.

    Modelling of influences of sensor reflection on the accuracy of a microwavev reflectometer
    (2014) Klyuchnyk, I. I.; Miroshnik, M. A.; Tsekhmistro, R. I.; Warsza, Z. L.; Zaichenko, O. B.
    In this paper the uncertainty component of a multisensor microwave reflectometer dependent on mutual reflections between sensors is described. One-line and two-lines arrangement of the set of sensor localization are considered. Adjacent sensors influence each other. The mathematical model of signal flow graphs of such a system was developed. The set of linear algebraic equations incorporating main reflections between sensors was worked out. The least squares method or Kalman filter for averaging the sensor signals with random distortions is used. The uncertainty of measuring the power by the multi-sensor reflectometer is estimated. The obtained results are discussed. The described methods of the uncertainty evaluation can be applied to automation of the multi-sensor reflectometer and in other multivariable measurements.

    Solving of sat – problems of artificial intelligence with the help of local elimination algorithms
    (Институт радиофизики и электроники им. А. Я. Усикова - научно-исследовательский институт Национальной академии наук Украины,, 2016) Miroshnik, M. A.; Tsekhmistro, R. I.; Demichev, А. I
    Using elimination algorithms are promising for solving of the problem of propositional calculus testing. These problems are widely used in the practical checking of digital electron circuits of modern telecommunications. Based on the fuzzy logic, acyclic graph these algorithms provides a way for typical presentations of SAT-problems.
