| Аннотация: | Relevance and objectives. Compression cuffs are widely used in tonometry. Along with creating excess pressure, they are able to form oscillations used to determine blood pressure values. The process of converting arterial pulse waves into oscillations depends on the anatomical features of the tissues under the cuff. Their mass characteristics help smooth out the frequency components of the oscillations perceived by the pressure sensor. The article is devoted to determining the amplitude-frequency characteristics of the pulse waves formed by the hydrocuff during decompression. It has been established that the high sensitivity of the hydrocuff tonometer makes it possible to detect and isolate high-frequency spectral characteristics in the signals of the hydrocuff pressure sensor. This allows, when implementing identification procedures, to obtain transfer functions that take into account the anatomical features of patients.It is proposed to use the hydrocuff technology for the process of oscillation formation. The study of the signals taken from the pressure sensor was performed on the basis of the analysis of the amplitude-frequency characteristics of the oscillations obtained during decompression and the passage of pulse waves through the walls of the brachial artery, musculoskeletal tissues of the shoulder, and the cuff to the pressure sensor. During the research, it was found that the oscillations contain a high-frequency signal spectrum in the range from 100 to 400 Hz. When using liquid as a working medium, transmission coefficient of the frequency spectrum increases by 17 times. At the same time, the phase distortion coefficient decreases by 4 times. | |

| Аннотация: | For the particle size distribution function various forms of exponential models are used to construct models of the properties of dispersed substance. The most difficult stage of applied research is to determine the shape of the particle distribution model. For the particle size distribution function various forms of exponential models are used to construct models of the properties of dispersed substance. The most difficult stage of applied research is to determine the shape of the particle distribution model. The article proposes a uniform model for setting the interval of information uncertainty of non-symmetric particle size distributions. Based on the analysis of statistical and information uncertainty intervals, new shape coefficients of distribution models are constructed, these are the entropy coefficients for shifted and non-shifted distributions of the Amoroso family. Graphics of dependence of entropy coefficients of non-symmetrical distributions show that distributions wellknown are distinguish at small of the shapes parameters. Also it is illustrated for parameters of the form more than 2 that it is preferable to use the entropy coefficients for the unshifted distributions. The material contains also information measures for the well-known logarithmic normal distribution which is a limiting case of distribution Amorozo. © 2021 Trans Tech Publications Ltd, Switzerland. | |

| Аннотация: | In the study of polydisperse materials, most of the experimental particle size distributions were obtained on bounded intervals. In these cases, it is also desirable to use bounded models with different shapes to simulate the results of studying polydisperse and powder materials. The beta distribution is often used to approximate results due to the fact that this distribution contains many forms for displaying realizations on a limited interval. With the development of computer technology, there has been an increased interest in the use of beta distribution in the modern practice of analyzing results. Meanwhile, there remains a limitation in the use of the beta distribution that is associated with the choice of distribution shape. The possibilities of using known shape measures for mapping beta distribution in this paper is discusses. On the example of the space of shape measure of kurtosis and skewness, the limited use of only probabilistic measures of shapes is illustrated. It is proposed to use the entropy coefficients as an additional informational parameter of the beta distribution shape. On the base of a features comparison of the entropy coefficients for biased and unbiased beta distributions, recommendations for their application are given. By using the example of beta distributions mapping in the space of asymmetry and the entropy coefficient, it is shown that the synergistic combination of probabilistic and informational measures of the shape allows expanding the possibilities of estimating the shape parameters beta distributions. Two methods to display the positions of realizations of beta distributions is proposed. There are trajectories on a constant ratio of shape and realizations position curve on equal values of one parameter. In particular, the features of the choice of beta distributions with negative skewness are discussed. | |

| Аннотация: | This paper contains parametric and informational measures of shape for various families of the generalized beta exponential distribution since it is important to determination of the distribution shape for analysing an experimental data set. A logistic parameter is used to select independent types of beta exponential distributions, that it allows to combine the distributions of different subfamilies. In this paper the use of parametric shape measures to predefine distribution shape is discusses. In particular, the initial and standard central moments for the main types of generalized beta exponential distribution are given. In the paper it is proposes to use the entropy coefficient of unshifted distribution as an independent information measure of the shape of unshifted generalized beta exponential distributions. In order to increase the reliability of the preliminary determination of the shape of the model, expressions for the entropy coefficient of shifted families both the generalized beta exponential distributions of the first and second types, and the generalized gamma exponential distribution were obtained. For practical applied the entropy coefficients of unshifted distributions for various subfamilies of generalized beta exponential distributions can be useful. © 2021 Institute of Physics Publishing.

| Аннотация: | The paper contains material on the choice of the form of distribution of income of the population and the assessment of the parameters of the stochastic volatility model, which are based on beta distributions. Since the mathematical description of complex systems is often built on the basis of distribution models that are given on the positive semi axis, then for these purposes, beta distribution of the second kind and its moments is often used. As the output arrays of complex processes are scaled in units of controlled physical quantities, it makes difficult to applied the classical moments method to analysis of the shape parameter of beta distributions. For this reason, the method of standardized moments is used to preliminary determine the type of distributions. However, this method makes not possible to estimate the shapes parameters of beta distributions. The objective of this paper is to study the possibility of using entropy coefficients to construct a display space for estimates of the shape parameters of the beta distribution of the second kind. Also, this paper addresses the problem of constructions of the diagram for the modelling shapes of the beta distribution of the second kind. | |

| Аннотация: | To better understand the distribution and host-parasite relationships, we explored 12 large regions of Russia and recorded new bat fleas (Insecta: Siphonaptera: Ischnopsyllidae) for Dagestan, Bashkiria, Mordovia, Khakassia and Buryatia Republics. Also we curate previously known data and registered new host-parasite associations for species belonging to genus Ischnopsyllus (Ischnopsyllus octactenus and I. variabilis ex Pipistrellus pygmaeus, I. intermedius ex Hypsugo savii, I. variabilis ex Myotis dasycneme, I. hexactenus ex Murina hilgendorfi) and species Myodopsylla trisellis. One of the associations we recorded in Altai republic is particularly interesting (Myodopsylla trisellis – Myotis blythii). Further investigation is required to study vector role of bat fleas and the effects of flea parasitism on their natural hosts. | |
