The problem of decreasing perinatal mortality is one of the pressing problems in modern obstetrics. Unfortunately, current methods of monitoring the intrauterine state of the fetus that are at the disposal of an obstetrician – gynecologist (сardiotocography, Doppler velocimetry) do not guarantee fetal wellbeing in the near-term outlook, and the num...

Transcranial magnetic stimulation (TMS) stands out among the rapidly developing methods for clinical rehabilitation of patients after cerebral vascular accidents. The method is widely used not only in post-stroke rehabilitation, but also in sports medicine, psychiatry and other fields of medicine. However, there is an unresolved issue related to pr...

This study aimed to develop a method allowing to improve safety of use of robotic medical rehabilitation devices by designing and testing an algorithm for calculation of the angular positions of rehabilitation robotic manipulators or robotic prostheses and allowing to reproduce the natural arc of a human arm under control of a CVS. The Introduction...

The design and substantiation of the pNLF filter based on a non-local averaging filter modification is presented. The filter is used for solving the problem of heart sounds amplification on fetal and human phonocardiograms for further tone segmentation and heart rate calculation relevant for fetal monitoring. The parameters for choosing the filter...

The paper considers the possibility of using a wavelet filter in cardiointervalography to isolate heart sounds against the background noise. The filtering conditions and requirements for the signal are discussed. The results of studies of the applicability of various types of wavelets for filtering model and experimental signals are presented and r...

The article describes the results of studying and analyzing phonocardiograms (PCGs) obtained during a physiological experiment with Blu-ray standard equipment. It provides the findings of a spectral and spectral-time analysis for signals with a sampling frequency of 10, 44.1 and 192 kHz. It shows that the differences in the PCG spectra of identical...

The article describes a mathematical model of physiological heart sounds created with due account for the pseudorandom generation parameters of component harmonic. The model uses the sine-cosine Fourier transform with probabilistic elements that are included to impart stochastic properties. These elements determine the frequency, origination time,...

Biped walking implies a multitude of cyclically moving body segments and requires corresponding adjustment and coordinated movement of these segments to ensure smooth motion and balance maintenance – a challenging task considering technical limitations of currently existing robotic platforms. The article describes the implementation of the real-tim...

The article describes an engineering prototype of the Device for 24-hour monitoring over the functional state of the fetus and mother’s cardiovascular system in the antenatal period of pregnancy. The Device is a hardware and software system that ensures the registration and analysis of fetus and mother’s phonocardiograms with further processing and...

The article provides an analysis of image processing and color segmentation applied to the problem of selection of homogeneous regions in the parameters of the color model. Methods of image processing such as Gaussian filter, median filter, histogram equalization and mathematical morphology are considered. The segmentation algorithm with the parame...
