When implementing such systems, occlusive inflatable cuffs are widely used. The oscillations formed inside them have quite a small amplitude of 1-2 mm Hg. This is one of the reasons for the emergence of various kinds of errors. Therefore, obtaining accurate values of systolic and diastolic pressures remains a serious problem for oscillatory methods with an inflatable cuff.This article presents a mathematical model that allows to take into account individual functional dependencies, linking the change in blood pressure in the artery with the form of oscillations in the hydro-cuff as a generalized transfer function, the coefficients of which can be established experimentally. This will allow measuring the hemodynamic parameters with high accuracy and assessing the critical state of the cardiovascular system reliably.","PeriodicalId":122716,"journal":{"name":"2020 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131606392","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}

Required analysis was performed for linear circuits with integral type transformations. It has been shown that in this case the probability distribution density of random functions is conveniently represented by an Edgeworth row. Analysis has shown that the average value of the output signal oscillates with some carrier frequency, and the dispersion has both axing and non-oscillating components. The convergence of output signal distribution is estimated for two typical cases. It is noted that the increase in the number of independent summing sum series converges to the normal distribution of prime at any finite values of coefficients of the named series. The results are obtained for the first initial moments of the signal, and their relationship with the coefficients of the investigated series is shown for a number of specific cases. The accuracy of approximation of the law of signal distribution distorted by random modules-steering noise was quantified. It is shown that under general assumptions about distribution of amplitude and phase distortions, the law of distribution of a signal distorted by stationary modules-steering interference can be adopted with sufficient accuracy by normal law with non-oscillating second moment only when a number of conditions are met. Example is given and analysis is carried out, including graphic analysis, of conditions of convergence of said law of signal distribution at output of linear circuit to normal distribution with oscillating second moment. In particular, it has been shown that with small phase distortions, the law of signal distribution approaches normal rather quickly with an oscillating second moment.","PeriodicalId":122716,"journal":{"name":"2020 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131740766","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}

So, involving both the bifurcation theory and the control theory into the research concerning regulator mechanisms of local climate evolution can give interesting results. For example, five years ago so-called HDS- hypothesis was proposed, in accordance with which local climate dynamics is determined by natural competition between the amplitude quantization (restricted by the temperature Hysteresis) and the time quantization (caused by the Double Synchronization). The conceptual model of local climate dynamics from this hypothesis (so-called HDS-model) first provided building bifurcation diagrams by processing the data of meteorological observations and also explained the phenomenon of the interannual variability from the bifurcation consequences. Here we discuss the HDS-hypothesis in order to find a way to soften the problem known within the limits of the traditional climatology, namely: how to research evolution of local climate dynamics under the essential scarcity of the data necessary to analysis. We use the electronic setup, mathematical model of which is equivalent to the HDS-model. We focus on complex behaviors when fast alternations of averaged meteorological variables (temperature, pressure, precipitation, and so on) can occur, which are not supposed to consider in the context of the traditional hypothesis on local climate dynamics. We compare the dynamics evolution made by the mathematical modeling with the observations made for both electronic and natural real systems. From the control theory, these results show striking similarity between the HDS- dynamics and local climate dynamics; from the climate theory, these results continue the novel interdisciplinary exploring in the local dynamics evolution.","PeriodicalId":122716,"journal":{"name":"2020 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133731773","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}

Each meter of this level gauge is divided into eight continuous measurement sub-bands, ending with a reference gauge block, due to which an auto-calibration of each measurement sub-band with an absolute error of Δ = ±0.3 mm is carried out. An accuracy control with the help of reference gauge blocks is carried out in each measurement cycle evenly throughout the whole range of level measurement of the controlled liquid. A technique has been developed for designing a discrete-continuous capacitive level gauge for a wide class of dielectric liquids with complex manufacturing of sensitive elements and gauge communication lines based on a one-meter printed circuit board.

Their peculiarity consists of the possibility of testing products and measuring their parameters without contact between the sensor and the test object. As before, it is relevant to carry out work to reduce the measurement error, expand the measuring range, reduce the influence of ambient temperature, and increase the reliability of the eddy current sensor design. By changing the active and inductive resistance of the sensor, the geometric and electromagnetic parameters of the test object are evaluated or the distance (lift off) between the end plane of the sensor is determined.It is shown that the measuring range of the eddy current sensor is determined by the nonlinearity of the calibration characteristic, and the important thing is not the value of the inductance of the winding, but its change from the gap, and the introduced inductance depends on the ratio of the geometric dimensions of the winding. The following electrical parameters of the eddy current sensor are determined: inductance, active resistance, own winding capacity, introduced complex resistance. The methodology for calculating the electrical parameters of eddy current sensors allows to increase the reliability of the test results. A design technology is proposed and the main structural and electrical parameters of the invoice parametric eddy current sensor used in vibration diagnostics of rotary machines for measuring the gap are determined. Computational experiments were carried out, that made it possible to evaluate the change in the electric parameters of the eddy current sensor depending on the measured gap to the control object.","PeriodicalId":122716,"journal":{"name":"2020 Moscow Workshop on Electronic and Networking Technologies (MWENT)","volume":" 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120830321","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}
