Abstract: The analysis of the nonlinear model equation is carried out. The nonlinear model equation in a Taylor series is expanded. It is shown that the bias in the estimation of the total standard uncertainty in GUM is due to the terms of the expansion of the second degree. To eliminate this bias, it is necessary to take into account the kurtosis of the input quantities distributions. A finite increments method for obtaining reliable estimates of the uncertainties contributions for nonlinear model equations is proposed. A practical example of calculation of comparison loss in microwave power meter calibration by various methods was considered. Estimates of the numerical value and measurement uncertainty obtained with GUM in this case have a bias. The result obtained with the finite increments method coincides with the results obtained using the Monte Carlo method.

Key-words: measurement uncertainty, nonlinear model equations, finite increments method, Monte Carlo method.

Abstract: A multisensory system for form deviation measurements of planar surfaces of large-scaled details is considered. The form deviation measurement requires preliminary information on the topography of the extracted surface obtained by measurement according to some output datum. In the reference plane method, such reference datum is the plane defined by three reference points of the support platform of the system when initially set it in a measuring position. At each subsequent position the current reference plane changes its position in space. To restore it to the initial position, adjustments are made to the parameters that define it by corresponding algorithms. Determination of these adjustments is made by overlapping measurement positions. The system has been successfully implemented in the control of the mechanical elements of the Buster and the Collider of NICA project, developed by JINR, Dubna

A POSSIBILITY TO DECREASE THE FLOW MEASUREMENT ERROR IN A CORIOLIS FLOWMETER BY EVALUATING ADDITIONAL PARAMETERS OF A TWO-PHASE FLOW

1) A.S. Semenov 2) I.I. Fedosov
1) South Ural State University 2) South Ural State University

Abstract: tract: A Coriolis flowmeter is one of the most demanded instruments from different types of flowmeters. It allows us to measure mass or volume of a flow that passes through a controlled volume of the space per unit time (for example, a section of a pipeline). The main advantage of a Coriolis flowmeter is an insignificant error of the flow measurement, which usually does not exceed 0.25%. However, this insignificant error is achieved only at a stable flow of fluid with a constant density. When a controlled flow has an inhomogeneous structure (multiphase or multicomponent flow), the error increases and can significantly exceed an acceptable value. In this paper, we consider the possibility of providing the required error of the flow measurement for a twophase flow in the Coriolis flowmeter. The possibility is realized by using additional parameters, that characterize the controlled flow.

Key-words: Coriolis flowmeter, two-phase flow, gas-liquid flow, error correction, statistical characteristics.

Abstract: Measurements of many power quality indicators are based on a spectrum measurement by means FFT. However, at a fixed sample rate and number of samples, the mains frequency deviation from nominal value causes distortions in the spectrum, often called spectrum leakage.

Abstract: The possibility for evaluation of the quality of electrical energy for the purpose of calibration of analyzers is considered by using a periodic square-wave pulse signal instead of the traditionally used harmonic signals. The square-wave pulse signal is represented in Fourier series, as each harmonic component is a function of the amplitude and the impulse signal duty ratio. Thus, its harmonic component is defined by strictly determined parameters much better than the parameters of a generated harmonic signal. A metrological analysis of the correction of the generated by the standard calibrator, values of harmonic voltages and currents has been performed.

Abstract: The aim of the present study is to investigate the possibilities of modeling the measurement of coagulation ability with a biosensor mechanical lactadinometer using different enzymes and concentrations. Coagulation times and curd firming time were found in 420 whole goat milk samples. Four enzymes were tested with 4 concentrations each and one control group with standard chimosin recommended by the manufacturer. The analyzes were made using the Polo Trade-Computerized Renneting Meter. There is a credible opportunity to considerably shorten the coagulation time of goat milk despite its specific rheological characteristics. There is a credible possibility to shorten the curd firming time, albeit considerably less than the coagulation time - 0.55 min for the control group at 2.6 min in the experiments with the lowest values. Differences in the effects of enzymes and concentrations were found in the two test parameters characterizing the coagulation ability of the milk.

Abstract: One of the most acute problems of our time is considered - the problem of loneliness. The nature of this social phenomenon is analyzed. Loneliness is considered inextricably linked with the crisis in communication. At the same time, communication is seen as the substance of human existence. Loneliness is not substantial; it is only a consequence of the unsatisfactory quality of the available forms of communication. Therefore, it is possible to minimize loneliness only by improving people's communication. Transformation of communication and overcoming of the most acute forms of loneliness is impossible without measuring its basic characteristics. Particular attention is paid to the analysis of compensatory communication as a way of harmonizing the world of personal communication. It is also taken into account that compensatory communication gives us both (+) and (-) harmony.

Abstract: Nowadays it is widely accepted that there is not one "truly human" calendar or reference clock for measuring human lives, because analyzing personal information involves many distinct kinds of measurement and there is no conceivable way to harmonize various temporal rhythms, scales and dimensions coordinating all of them. Yet, previously it was suggested that even though we cannot predict the details, we might discover the existence of the universal laws that govern the overall dynamics of complex highly organized systems, such as human culture or social order. This paper will show that S. Prokofiev's personal diaries can illustrate both the complexity of human life and a possibility to discover an interrelated set of natural rhythms reflecting it.

Abstract: It is shown that the results of the evaluation of the object of inspection parameters are inevitably associated with uncertainty due to imperfections in this procedure, equipment and the influence of external random factors. Reduction of this influence is especially important within certain limits around the limits of the tolerance interval while reducing the number of additional measurements. Therefore, the decisive rule on the suitability or unsuitability of the inspection object should take into account both the possible uncertainty of the result and the requirements for the cost and complexity of the verification procedure, as well as the specified reliability. It is shown that the application of the algorithm makes it possible to increase the probability of making the correct decision about compliance for each object under test and, in comparison with known methods, does not significantly affect the decrease in productivity and increase the cost price of the product. The practical use of the algorithm showed that 5 additional stages of the study make it possible to reduce the probability of false decisions by at least 3 times, while the increase in control operations does not exceed 60%.
