Abstract: As known, the real conversion characteristic of the measuring system is different from the nominal characteristic. During the measurement control this may increase the probability of erroneous decisions. In this connection it is necessary during calibration to transform the conversion characteristic, bringing it closer to the boundary areas of the nominal. The transformation of the characteristics may consist of several cycles, each consisting of two phases - a multiplicative and an additive. For selecting the type of transformation and the number of cycles it is necessary, first of all, to review the relationship between the components of errors of the conversion measuring system and the length of the tolerable interval. Relationships which allow us to estimate the probability of erroneous decisions both within the cycle and in the transition to the next cycle of transformation are obtained.

Key-words: measurement channel, real conversion characteristic, nominal characteristic, measurement control, multiplicative and additive cycles, probability of erroneous decisions.

Abstract: In present times the discrete Fourier transform is the most commonly used technique for measurement of spectral parameters. However, the accuracy of this method is limited due to possible deviations of input frequency from the nominal value. This leads to the so-called effect of "spectrum leakage", leading to an additional measurement error in spectra amplitude and phase. The effect of "spread spectrum" cannot be fully addressed by the existing methods and for its reduction an implementation of additional devices or algorithms is required. The method of quadrature demodulation is an alternative to the classical approach based on the discrete Fourier transform. In the report a research is carried out for determining of the spectrum of a signal based on the quadrature demodulation. The received analytical expressions allow to estimate the error in the measurement of the spectrum and the frequency of the signal. The accuracy of the analytical relationships is confirmed by the results of the mathematical simulation performed using the software packages Matlab and Simulink.

Key-words: signal spectrum, Fourier discrete transform, quadrature demodulation, spectrum leakage, frequency deviation.

Abstract: The ensuring of the quality of electrical energy depends on all factors related to its generation, distribution and consumption. One of its most important parameters is the stability of the network voltage. A major way to ensure such stability is to embed On-Load Tap Changers in power transformers. The paper is devoted to the hardware and software of the virtual instrument developed for measuring the torque during the switching process of a diverter switch. The hardware is based on a torque measuring sensor which uses strain gauges for its determination. It can be used for every diverter switch with appropriate connecting elements. The software is developed in LabVIEW environment. The results from measurements of a tested diverter switch are presented.

Abstract: When non-sinusoidal voltages are measured the bandwidth of the measuring instruments can have a significant impact on the results. This work aims to assess this impact when it measures the root mean square voltages of three-phase inverters that feed induction motors. By using numerical modeling in PSpice it is shown that under naturally sampled pulse-width modulation, at switching frequency of 4 kHz, there is possibility to achieve errors less than 5% in case the measuring device has a cut-off frequency above 100 kHz.

Abstract: Accelerometry is a method for measuring of acceleration, and accelerometer is a converter which measures the acceleration of moving objects [13]. With this instrument the increase of the mechanical quantity is measured, which is an instrumental method for the measurement of accelerations [8]. On the basis of technology transfer the method is widely applied for various motor activities in sport. For these purposes accelerometers are distributed, designed mostly on tenso or piezo principles. They are mounted on a moving device, equipment or certain points on the body so that the direction of the measurement coincides with the direction of the motion of the system. Indirectly speed also can be measured as the recorded acceleration is integrated by an appropriate device. In modern amplifiers integration is automatic. The process needs systematization and examples for a particular application from which we selected to study specific performance.

1) KNTSU, 4E, Prospekt Hlushkov, Kyiv, Ukraine, e-mail: yarovoi@univ.kiev.ua

Abstract: The paper concerns a modified laser Doppler vibrometer (LDV), namely the LDV with three interfering coherent waves is proposed unlike two ones in classical LDV. The three wave layout results in an appearance of a signal extra gain at the vibrometer output, but only under special conditions. One of them relates to exact establishing of a zero-phase difference between two interfering optical channels. We studied this problem and obtained analytical and numerical relations for the key characteristics of the vibrometer as function of the phase difference and an error of its determination. The paper shows that the wanted zero-phase difference can be obtained precisely by analyzing a spectrum of vibrometer heterodyne output for a probing single harmonic vibration. An experimental verification that demonstrates some aspects of considered problem was carried out by a setup based on modified Polytec CLV vibrometer.

Abstract: Till now, humanitarian knowledge and appropriate measurements have not experienced the shock which would be caused by entering the informational phase both of life and science. Meanwhile, due methodological changes can become a key for progressive development both of social sciences and social life itself. However, such a progress requires quantitative approaches which should take into account rather sharp inter-personal inequality (which responds to “hyperbolic distributions”), in tandem with informational features of activity. The measurements proposed, overcome numerous “truisms of evidencies”, which sometimes even cause mass psychoses. Results of such measurements can be used when working on recommendations for cultural and social politics.

Abstract: To identify the parameters which are of prime importance both for mental and social life, it seems prospective to proceed from the measurements of correlation between different parameters. Typical example of such identification is 'principal component analysis, based on expert scores put to various sets of objects (and/or subjects). In the given investigation such an approach was used to measure the 'neural force' of creative persons. Though the concept of 'neural force' is well known, it was 'renewed' due to theoretical studies in the framework of the systemic-informational approach. The raw material for the investigation consisted of 16 parameters of 102 eminent composers of the 17th – 20th centuries (both West-European and Russian). Inter-parametric links permitted to introduce the 'index of neural force' for each creative personality, i.e., his/her inclination either to 'weak' or 'strong' pole, basing on only three parameters. Most results obtained are statistically significan at the level better than 1%.

Abstract: Extension of measurement borders to the field of sciences studying man and society requires that quantities, which in most cases are multidimensional, have strict definitions. Definitions of these quantities and development of corresponding measurement models can contribute to revealing new dependences and processes unknown before. This statement is illustrated by the example of the model for measurement emotions caused by music fragments. It follows from the model that the effect of nonlinear conversion of current and previous soundings is realized directly in the brain as well as emotional perception of music changes with age in a certain way. Specific features of measurements of neurophysiological reactions are noted. Experimental results have proved the efficiency of development of a measurement model as a cognition method.

Abstract: The objective measurements of processes in the evolution of socio-cultural sphere are one of the important scientific directions. The paper deals with historical statistics of musical culture calculated on the basis of data given in the well-known Grove’s dictionary (2001). The Grove’s dictionary has been firstly analyzed in order to use only reliable data. The persons are selected according to Zipf-Mandelbrote low which describes the usual distribution of text volumes in such issues. The ‘significance’ of different kinds of musicians — composers, performers etc., measured on the basis of the text volume devoted to the person in Grove’s dictionary, has been analyzed from the viewpoint of statistics and historical changes. Also the actual number of musicians in various historical time periods has been studied as a statistical parameter, which changes in historical time. Possible correlation between these parameters for different kinds of musicians and culture regions has been studied.

Abstract: The effect of "singing on the piano" is one of the most mysterious phenomena in the field of music. The traditional paradigm of musicology can not provide valid explanations for it. From the viewpoint of the information approach the "effect of singing on the piano" is neither more nor less an "optimal strategy" presentation of the musical material. However, an unambiguous answer to the question of the reality or illusory effect should apply to measurements that implies assessment of measurement error. The study of music pieces is performed using wavelet analysis.

Abstract: Apart from the physical properties of papers, the way it looks to human observer is also important, especially to the end user. A lot of formatted paper grades, used for offset, inkjet and laser printing contain fluorescent whitening agents. The tendency is to manufacture papers with ever greater whiteness. Whitening of paper pulp, adding additives to paper and coating it, as well as adding fluorescent agents aim to increase its whiteness. But still the influence of these additives on the paper whiteness/brightness is limited due to porosity issues. Papers with high whiteness can only be manufactured with the correct use of fluorescent agents. This research aims at measuring specific parameters of printing papers used in color managed environment.

Abstract: An interlaboratory comparative measurement of the activity concentration of radon in air is conducted with three AlphaGUARD Radon monitors, owned by the laboratories participating in the comparison. The three AlphaGUARDs have calibration certificates. The monitors are placed in a closed system in which, in succession, are injected activity concentrations of radon of order 3000 Bq/m3 and 12000 Bq/m3. The activity concentrations measured by the three monitors are compared. The deviation of each monitor from the average and the Z-score are calculated. The deviation of the measurement of each monitor from the mean value is less than ± 3%. The values of the Z-score for all three devices range between -0.09 and 0.28. The results show that all three Radon monitors retain their metrological characteristics and do not require re-calibration. Interlaboratory comparison is a good laboratory practice and can serve to justify the need of new calibration.

Abstract: In the paper the methods for the determination of the calibration intervals of measurement equipment, with an emphasis on the application at inspection bodies according to ISO 17020, are analyzed. An overview of the already established classical methods according to ILAC and other internationally published guidelines for the determination of calibration intervals is presented. As a result of the analysis, a new modified method (algorithm) to determine optimal intervals depending on the analysis of the history of the calibration results and mutual checks with measuring instruments with the same or higher accuracy class is proposed. The conditions, usage habits, behavior history of the measurement instruments as well as other factors that may affect the stability and the accuracy are embedded in the analysis and the regression modeling. The proposed methodology is experimentally verified through experimental data of real measuring equipment used for control purposes in inspection bodies.
