The problems of synthesis of a model of dynamic neuron with state memory (DNSM) are considered in the paper. The introduction of a special additional parameter into the model of a neuron, defined as a state parameter, is substantiated. It is indicated that the parameter of the state of the neuron has the ability to vary with time depending on the nature of the information processes that occur in neighboring neurons of the network. This parameter in a certain way accumulates information about the history of the behavior of the neuron in accordance with the entered formal descriptions. The concept of a "strained neuron" is introduced, taking into account the above. This concept characterizes the degree of influence of a given neuron on the neurons surrounding it. On the effects of time-varying parameters of the state of neurons, it is proposed to implement the process of self-evolution of the network directly during its operation. A variant of the analysis of the structure of the neural network, created on the basis of the proposed model DNSM. The topological representation of a neural network in the form of a graph model allows formalizing the interaction of neurons in a network with each other, both in time and in space. For this, the concept of k-space is introduced, which determines the degree of proximity of neurons to each other. The degree of proximity of neurons allows one to formalize, in the form of mathematical relationships, the procedure for the exchange of information between neighboring neurons in a network. Mathematical relationships that formalize these processes are given. A variant of the structure of the hardware design of DNSM, focused on implementation using FPGA technology, is proposed.

Predictive assessment of the technical object is based on the determination of the possible values of the controlled parameters in the projected time period and is carried out during the operation of the object. Calculations are usually done in the background and it is important to estimate the minimum sample of parameter values that can be used for prediction. The article shows the possibility of using the Hurst indicator to determine the persistence of the time series of the object parameter and presents a scheme for estimating the minimum sample size, which can be used to reliably predict the parameter change using time series forecasting methods.

Today one of the topical issues is the practical application of the theory of pattern recognition, face recognition, including the definition of a person in the image and its subsequent identification. Such tasks include the extraction of indirect signs of interaction between users of social networks. By identifying the user's face and further searching it in photographs and video files in other profiles, an expansion of the list of basic data available to the analyst is achieved. It is known that the system of computer vision, which is able to recognize faces in a natural and artificial environment under any conditions, has not been implemented to date. One of the obstacles is the variation of the scene - the area where the face is being identified. The article proposes a model of an intelligent information system using bion-spirited methods for preprocessing images in order to expand the range of allowable scene variations.

This study examines the dynamics of the perception of individual segments of the advocacy news. A probabilistic-stochastic approach for simulation is proposed. As the main actor describing the situation, the probability of a positive assessment of the veracity of the new information by a separate subject is taken. For the description of the process of forming the relation to it the discrete-event paradigm is chosen. The change in the level of evaluation occurs under the influence of random perturbations of the individual's opinion, experienced at discrete moments of time. An intuitive recalculation after this perception of the news is modeled based on Bayes ' theory of decision making. Mathematically, this approach fully coincides with the previously used by us in the numerical analysis of the resolution of intrapersonal conflicts. The results revealed at that time were adapted to study the dynamics of the perception of propaganda news by a neutral part of the population. Which is made by the individuals estimating truthfulness of propaganda activity as a whole neutrally, at the level of ½ (on a scale from 0 to +1). It is found that when assessing specific news such neutrality is violated, in the end, the individual believes the news is either completely true or false. But it is already being restored at the level of the ensemble of all news. About half of them are considered by the individual to be true, half – false. The time before the formation of the final perception of a particular news depends on the degree of its importance for the subject, and the minimum is observed at the level of significance slightly below the maximum. The model of taking into account the social environment in the resolution of intrapersonal conflicts has also been adapted for the analysis of the perception of propaganda information. While the assessments of the credibility of the individual stories of neighbors are correlated. Over time, clusters with the same perception are formed in society. Ideally, in the absence of other influences, eventually one opinion is formed in the whole study group. Here again, for some propaganda news, the neutrality of perception is broken, but it is restored at the level of the ensemble of all news. The proposed models can be used to study not only the neutral part of the population, but also groups with any level of assessment of the truthfulness of propaganda in General, both homogeneous and heterogeneous in this parameter. In addition, the proposed approach can serve as a basis for the study of the impact of agents of influence (in the information space) and the development of advocacy strategies.

The simulation variances of the final volume considerably simplifies the solution of certain problems of reliability. The collection of information for aggregates of large volumes is impractical because of the duration and high cost. Therefore, the analysis and calculation are subjected to a representative sample. To move from sample data to finite volume population parameters, an analytical method for determining the Weibull parameters for the population was used. Analysis of the analytical method for determining the parameters of the three-parameter Weibull distribution for the aggregate confirmed the possibility of using the method of modeling statistical data of strength and life of parts and components of machines. The calculations proved that in practice it is possible to use both the value of the shift parameter and the value of the extreme terms of a number of the population.

The article conducts a study of the stress-strain state of the protective structure, taking into account temperature and radiation effects. Dry protection is a thick-walled cylindrical shell rigidly clamped at the base. The analysis is carried out in axisymmetric formulation. The calculation of the stress-strain state is preceded by the determination of the distribution of physical fields in the thickness of the structure. The stationary temperature field is considered taking into account internal sources of heat release. The diffusion approximation is used to determine the distribution of the neutron fluence. The calculation is performed numerically using the finite element method in the Matlab package. The results are compared with and without induced inhomogeneity. The significant influence of inhomogenity on stresses in the structure is shown. At the same time, taking into account heterogeneity does not lead to a significant change in displacements.

The article is devoted to the issue of improving the environmental safety of the construction industry by improving dust collectors of dust removal systems for the aspiration schemes of the construction industry/ It was proposed use additive-integrated dispersive analysis of variance of dust particles emissions throw out into the atmosphere by aspiration systems. The article proposes the improvement of complex analysis of variance using hydrodynamic criteria in output functions. Modified output data and additive-simplex allows getting approach to evaluate characteristics - equivalent sizes and speeds of sedimentation-soiling of dust particles with a higher degree of accuracy of the results. It makes possibility to determine the ranges of size’s and velocities’ changes with real ability. It is possible to obtain more reliable data of sedimentation rates and equivalent particle sizes for the studied dust samples of building materials using the distributions of the hydrodynamics criteria. Analytical approach to determining the density’ distribution of the numerical values of the hydrodynamics criteria in the output function allowed us to clarify the more real values of sedimentation rates and the equivalent particle sizes and the range of their changes both. This way analysis of variance of dispersed dust particles could call additive-complex or simplex approach. The obtained regressions in processing the research results were used in the development of devices for capturing dust of dispersed building materials from emissions. This way could significantly reduced dust leakage out from aspiration collectors of decreasing dust systems while purifying emissions at the building enterprises. This approach is one of the most effective ways to improve the environmental safety of the building industry.
