    Identification of drones in a defined territory
    (Видавництво Львівської політехніки, 2018-09-18) Nakonechnyy, A.; Berezhnyi, I.; Lviv Polytechnic National University
    Different modern methods of detecting drones, which are based on various physical principles of signal transformation and processing, are examined and analyzed. The system of identification of drones is proposed, the basis of which is the analysis of signals of vibration and oscillations of the body. The work of the system is based on the processing of signals in time-frequency, wavelet area. After the identification of the drone is given a method of creating interference and interception, to further eliminate it.

    Work diagnostics of the vehicle's engine using vibroacoustic characteristic
    (Видавництво Львівської політехніки, 2018-09-18) Nakonechnyy, A.; Hetman, O.; Lviv Polytechnic National University
    The report presents the essence and necessity of diagnostics of the vehicle’s engine using vibroacoustic characteristics. To improve the analysis, we suggest using wavelet transforming signals.
