High-Resolution Phonocardiogram Parameters

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 signals are unreliable. The article specifies the onset and disappearance moments of the harmonic components of heart sounds. It also provides recommendations on the sampling frequency and bit resolution of digitized PCG signals for telemetric systems

A mobile full-time daily system for fetal monitoring

The article describes a mobile hardware and software system designed for daily monitoring of the state of fetal and maternal cardiovascular systems. The assessment is carried out by means of recording and further online analysis of acoustic data, obtained from the abdominal surface of a pregnant woman’s body. The components and operating principles of the hardware and software system designed are described. The results of experimental studies aimed at assessing the applicability of a method of acoustic data analysis implemented in the system developed are shown. The results obtained have been compared with the results obtained using cardiotocography

Joint Activity of Autonomous Actors in an Open Educational Environment

Recently, a considerable literature has grown up around the theme of the transition to the digital economy, the increasing value of the individual with unique features and the ability for self-conscious activity. In order to improve the quality of teaching, it is necessary to develop a methodology of targeted application in the education of jointly distributed activities, characteristic of modern youth.In this regard, this article aims at the development of the assessment criteria and identification of actor’s autonomy levels and their joint activities in the educational process, and definition of methods for organizing jointly distributed activities of autonomous actors in the education.The leading methods in the study were monitoring the activities of teachers and students in social networks, especially on educational communication platforms, identifying and comparing the characteristics of these activities; analysis of the products of educational activities of students interacting in educational networks; expert assessments to determine the level of quality of the achieved results.The article justifies the criteria of assessment of the levels of the educational actors’ autonomy and their activities, developed the methods of organizing jointly distributed activities of autonomous actors of the educational process and revealed the possibility of changing their functional roles depending on the type of their interaction.The materials presented in the article allow creating the organizational and methodological conditions for the formation of virtual training groups, taking into account the level of preparedness of autonomous actors for joint educational activities in order to improve the quality of teaching

The Modern Approach to Virtual Laboratory Workshop

The method of computer simulation of microwave measurement units and special laboratory workshop for engineersâ?? education are described. Simulated laboratory has a module structure. The basis for constructing a model of the specific work is a concept of the abstract â??deviceâ? with front panel view and manipulation principles identical to those of the real units
