Item Higher order spectra analysis for assessing stationarity(Видавництво Львівської політехніки, 2013) Stavorovsky, Konstantin; Popov, AntonIn this paper the new approach to investigation of signals stationarity based on parameters of bispectrum is proposed. The method was examined using simulated test signals artificially test signals with predefined nonstationarities. As test signals Gaussian noise with varying variance and mean value were proposed. Proposed bispectral characteristics are different for stationary and nonstationary signals.Item Identification of epileptiform complexes in electroencephalogram using adapted continuous wavelet transform(Видавництво Львівської політехніки, 2010) Popov, Anton; Zhukov, Mykhailo; Kanaykin, Alexey; Bodilovsky, OlegIn this paper the new method for time localization of epileptiform complexes in the human electroencephalogram is presented. The use of patientadapted mother wavelet function allowed to reach the 93 % of true positive identification rate and 32 % of false positive identification rate.Item Mathematical model of channel current in FET-based nanobiosensors(Видавництво Львівської політехніки, 2012) Bodilovska, Daria; Popov, AntonField effect transistor (FET)-based sensor for biomolecules detection has been simulated.Item Reccurence plots parameters during epileptic seizure patterns onset(Видавництво Львівської політехніки, 2013) Popov, Anton; Topikha, OleksandrThe purpose of the paper is to investigate the applicability of recurrence plots paremeters for early detection of epileptic seizures. Trends of Recurrence Rate and Determinism of electroencephalogram recurrence plots are calculated for different time windows. Experiments show that both parameters start to grow approximately 250 seconds in advance of epileptic seizure activity onset for time window of 5 minutes.Item SpO2 and PetСО2 signal analysis in closed-loop mechanical lung ventilation systems(Видавництво Львівської політехніки, 2012) Bodilovskyi, Oleg; Popov, Anton; Zakorchevnyi, MykhailoEmployment of SpO2 and PetСО2 signal analysis for setting parameters of mechanical lung ventilation in closed-loop systems is considered. Results of time-frequency representation of such signals are presented and discussed.Item Time-frequency representation of SpO2 signal(Видавництво Львівської політехніки, 2012) Popov, Anton; Zakorchevnyi, Mykhailo; Bodilovskyi, OlegIn this paper the time-frequency analysis of blood oxygen saturation signal is performed and spectrograms of SpO2 signals for different conditions are presented.
