Abstract: Measurements of many power quality indicators are based on a spectrum measurement by means of DPF as the effective algorithms of its computation having the general name FFT are developed. However in case of the fixed sampling frequency and number of counting the mains frequency deviation from rated value causes the distortions of spectrum called by spectrum leakage. To reduce spectrum leakage, sampling frequency is set up under mains power frequency. One of methods of setup uses periodic measurements of mains frequency. However the error of these measurements restricts reduction of spectrum leakage. In the report results of a research of a voltage (current) spectrum measurement error because of a mains frequency measurement error are provided. Results are received by method of analytical and simulation modeling.

The failure detector is designed and set up to operate the original signals, which leads to problems in its operation as follows: spurious actuation of a signal for blown fuse (s) or, which is worse, failure to actuate the signal when the fuse is blown. In order to prevent similar problems, a decision was taken to install a device for phase and amplitude correction to enable the change in the phase and amplitude of the signals.

Abstract: The report describes the methods for the calibration of digital pressure gauges, combined pressure gauges and vacuum gauges developed by the Laboratory for Pressure, Flowrate and Level Measurement in Metrology Assurance Department. The methods were developed in order to provide the traceability of the measurement results for the above pressure gauges at Kozloduy NPP. The calibration is performed with a piston pressure gauge (further in the text referred to as reference pressure gauge). The purpose of the methods is to find out the difference (deviation) between the pressure measured by the calibrated and reference pressure. In the process of calibration, the real values of pressure are identified in the measuring unit of the calibrated pressure gauge both in pascal , [Ра], or its multiple from the SI international system. The main sections defining the conditions, methods and nature of calibration, as well as processing of calibration results are reviewed.

Abstract: in the report, having a survey character, methods and measuring apparatuses of the parameters of acoustic field created by ionizing radiation are presented. The basic attention is given to works of the Russian scientists from VNIIFTRI (ВНИИФТРИ) and the Institute of Theoretical and Experimental Physics – ITEP (ИТЭФ) and to the experimental results obtained by proton beams. A method of a scanning hydrophone is developed, realized as a device, and approved for the investigation of the space-time structure of the hydro acoustic field created by the beam of high energy particles. The space - time structure of the acoustic field, excited by the beam, has been obtained, for the first time, with good resolution, in experiments on ITEP proton synchrotron. Parameters of the angular distribution of the hydro acoustic radiation created by proton beam have been measured. The results of experiments, performed in collaboration with the scientists of the Scientific Research Institute of Nuclear Physics (SINP) at the Moscow State University in a water target on the electron accelerator are reported. The offered methods and means and the formulated metrological concept allow, at the modelling of the cascade shower in water medium by a beam of protons or electrons, to obtain values of the acoustic radiation parameters, having high extent of metrological reliability. The developed method gives the possibility of both revealing of general laws of acoustic field generation by different nature particles and the differences in radiation effects, created by them.

Abstract: Contemporary computer techniques of sound pitch analysis provide results with accuracy near to human’s resolution of hearing. Further precise examination of traditional music performance requires fixation of sound pitch variations. Usually, European musicologists apply for this purpose musical notation (score). This kind of fixation means quantization on sound pitch, i.e. rounding of exact values to ‘allowed’ pitch levels, and also quantization of sound durations. Melody notation in academic music uses 12-halftone equal-tempered system. There exist also systems with more stages in octave. For durations, a row of time units like 1/32, or 1/16, or 1/8… will be used — with certain main tempo. In the paper, quantization error values will be analyzed in dependence of number of pitch row stages in octave, used time units and different character of melody line.

Abstract: The evolution of some social systems is subdued to ‘regression to the mean’ (F.Galton, H.Eysenck). Earlier this phenomenon was measured in application to subjective ‘feeling of well-being.’ In the given study, the pedagogical process (151 students, each tested 16 times during two semesters) showed similar results: though of conserving average level of exam marks, the changes in their distributions during a half a year, evidence of diminishing marks for former advanced persons, together with increasing values for backward students. This ‘regression’ is measured by appropriate indicators, including rank correlation between the students’ hierarchies (over their marks) while the educational process, – its quality being also reflected by this phenomenon. Besides, in relation to creative abilities, ‘regression’ is an indicator of their ‘partial decay’ – due to so-called ‘abneguism,’ but sometimes it is compensated by the trend towards ‘Mathew effect’ (resulting in hyperbolic distributions, e.g., Zipf’s law).

Abstract: In carrying out experimental psychological research you may come across multidimensional probability distributions, meanwhile you may observe significant correlation links between components of these distributions. At the same time, a hypothesis about the existence of functional dependences between the random variables under study can be naturally expressed. The proposed method is illustrated by examples of determining the dependencies between the level of anxiety( AP) and ( AR ) and existential personal characteristics (self-distancing - SD, sub-scale F - Freedom, subscale V - responsibility, self-transcendence - ST). It is shown that the increase in anxiety indicators is accompanied by a decrease in personal existential characteristics..Quantitative data are provided

Abstract: Given the normal distribution of quality indicators, the coefficients for calculating control limits for Shewhart cards are derived. The output of sample values beyond the action limits is an unlikely event. Its appearance indicates the presence of systematic influence and there is a need to adjust the controlled parameters of technological process. On the basis of practical experience in the ISO 7870-2: 2013 standard it is recommended to pay attention to "... any unusual structure of data points, which may indicate about a manifestation of the special (non-random) reasons". In the numerical example presented in this work the analysis of a structure of points on the control chart showed the presence of non-random values, although the sample mean values were within of action limits. The indicator of existence of a non-randomness was the probability that the minimum number of consecutive selective averages which got to a certain area did not exceed 0.003. As a result of executed analysis the criteria are established and the algorithm is developed. It helps to identify the dysfunction of technological process at an early stage.
