The model describes the formation of the duration of heart contraction intervals (RR intervals) due to the action of the system of \"generation\" of global and local random events. The sequence of such events in time is considered as a random doubly connected flow. Let’s represented two classes of random time intervals between the events of such a stream: local and global intervals. Assume that global intervals are random intervals local sum and the sum value is a discrete random variable with a binomial (or Poisson) probability distribution. The relationship between the parameters of the developed probabilistic model and existing models for describing the electrical activity of the heart as a process of propagation of an excitation wave in a complex anisotropic biological medium are showed. Equations for estimating the values of the probabilistic properties of informative parameters that reflect the dynamics of intracardiac electrical activity are obtained.","PeriodicalId":235261,"journal":{"name":"2020 IEEE 4th International Conference on Intelligent Energy and Power Systems (IEPS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116712483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, frequency data of PMUs are used effectively for identification of SSOs. These frequency data inevitably contain slow trends and measurement noise, which degrade the identification accuracy of SSOs. A signal of the trends is removed simply by a highpass filter, while it is not easy to remove the noise. This paper proposes an identification method of SSOs using bandpass filters with a narrow bandwidth for removal of the noise. A center frequency of each bandwidth is specified as an individual SSO frequency. A signal of each SSO is extracted from the frequency data by its bandpass filter. The noise is negligible in the extracted signal. A sum signal of the extracted signals for all the SSOs can be expressed as an autoregressive (AR) model, of which the coefficients are estimated from the sum signal by applying the least squares method (LSM). The proposed method is evaluated through simulations on the trend signal and signal-to-noise ratios (SNRs). Simulation results of the proposed method are compared with those of a Prony method, which uses the singular value decomposition (SVD) to cope with the measurement noise.","PeriodicalId":235261,"journal":{"name":"2020 IEEE 4th International Conference on Intelligent Energy and Power Systems (IEPS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131963151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis takes into account the possible variation of the film thickness and the divergence of the incident beam. The modeling of the experimental transmission and reflection spectra shows the possibility of identifying the interfacial interaction at the boundaries of thin-film layers of cadmium sulfide and cadmium telluride leading to the formation of varison layers of solid solutions. In addition, modeling has shown that the coordinate-dependent permittivity of solid solutions leads to a significant increase in the reflection coefficient from the structure. The principal possibility of determining the parameters of solid solutions based on the spectra analysis of the transmission and reflection, measured at different angles, is indicated.","PeriodicalId":235261,"journal":{"name":"2020 IEEE 4th International Conference on Intelligent Energy and Power Systems (IEPS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115348956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The remaining but modified healthy phase currents are obtained for a single-phase, adjacent double-phase and non-adjacent double-phase open-circuit fault conditions. The proposed fault-tolerant control strategy is validated by finite element analysis (FEA).

Currently, it makes up about 1.5-2% of the total population (average age 75-85 years), and it is expected that by 2050 it will be about 30 million people in North America and Europe. This is associated with a five-fold risk of stroke, a triple increase in the risk of heart failure, increased mortality and hospitalization. Currently, methods of non-linear analysis of heart rate variability, which are successfully used in many scientific studies, are becoming more common. In practice, for detecting AF, graphical methods of rhythm analysis are often used: construction of correlation rhythmograms (Poincaré plot), analysis of histograms of RR intervals and three-dimensional scatterogram. They provide visual information on the nature of the heart rhythm, that is, they are visual methods for analyzing the sequence of cardiocycles, and can be used to solve the problem of automatic diagnosis of AF.
