Published: November 2020

In the paper proposes a analog of the method E. Rote (the method of semi-discrete by time variable) to construction converging different schemes when analyzing the mathematical models of network-like oil and gas processes. The proposed method reduce the study of the input initial boundary value problem to study the boundary value problem in a weak setting for elliptical type equations with distributed parameters on the net-work. Thus, there is another possibility, besides the Faedo-Galerkin method, to construction approaches to the desired solution of the initial boundary value problem, to analyze its stability and the way to prove the theorem of the existence of a weak solution to the input problem. The approach is applied to finding sufficient conditions for the existence of weak solutions to other initial boundary value problems with more total boundary conditions -- in which elliptical equations are considered with the boundary conditions of the second or third type. Further analysis is possible on the way to finding the conditions of the Lyapunov stability. The approach can be used to analyze the optimal control problems, as well as the problems of stabilization and stability of differential systems with delay. Presented method of finite difference open new ways of approximation of the states of the parabolic system, analysis of their stability when numerical implementation and algorithmic of optimal control problems.
To continue the optical-mechanical analogy
Authors: Valishin N T , Volkov A I , Bildanova Z F , Selivanova V A
Published: November 2020

On the basis of the V-function method, an optical-mechanical analogy is carried out; and further it receives a new continuation. In particular, the equality of the phase velocity of the wave and the velocity of the particle is shown. It is noted that according to its physical meaning the wave characterizes the properties of the action that manifests itself in the motion of the particle. The V-function method is based on the concept of a process-state and it consists of a local variational principle, a new formulation of the direct and inverse problem of dynamics. According to the V-function method, the trajectory motion of an object is associated with its wave motion. In this case it is assumed that there is an explicit connection between the trajectory and wave equations of the object. The application of the V-function method for the case of rectilinear motion of an object is shown.
Time and phase synchronization in communication system with a digital pseudo-random modulation
Authors: Kokin D S , Ponomarev O G
Published: November 2020

The paper is concerned a model of a digital communication system where the samples of white Gaussian noise with zero mean and dispersion σ2are used as a modulated (carrier) low-frequency signal. Methods of the digital-phase modulation are used in a system for transmission of information message. The communication technology reminds CDMA (Code Division Multiple Access). However, a key of feature of this system is that digital samples of white Gaussian noise are used to increase the spectrum of the information message instead of traditional Walsh-Hadamard binary sequences. In this system the repeat period of the pseudo-random sequence values is specified by the parameter and can be equal to the time (duration) of several information symbols contrast to CDMA, in which the duration of repetition period equals to the duration of modulating symbol. On the one hand, the solution allows you to increase the confidentiality of the transmitted message and more evenly expand its frequency spectrum as compared with the existing of CDMA methods. On the other hand, scientists face two significant scientific tasks that make the work meaningful. First, it is necessary to ensure the synchronous operation of pseudo-random sequence generators in the receiving and transmitting devices. Secondly, it is necessary to define a phase shift amount of the frequency-change oscillator in receiving device. Both problems are the result of the asynchronous starting of the receiver. A control signal is used to solve these problems in the radio communication system which is transmitted simultaneously with an information message. So the result of modulator work is the sum of both information and control modulated signals. The proposed methods and algorithms provide the coherent signal processing with the digital pseudorandom modulation in the receive path of communication channel. The paper is a course of early research studies and it contains a detailed mathematical description of modulation and demodulation signals in the communication system with the digital pseudorandom modulation. The numerical model of the system is described in MatLab language. All numerical experiments were carryout in a mathematical computing system of MatLab.

Next, the problem is divided into three simpler edge subtasks. Expressions describing the evolution of the free boundary and the separation line of the liquid layers are obtained. This evolution is also represented graphically. Conclusions are made about the influence of the ratio of densities, layer width and source power on the process of wave formation.

Authors: Fomin D G , Dudarev N V , Darovskikh S N
Published: November 2020

The main lines in the development of wireless communication technologies are their microminiaturization, expanding the functionality of their built-in devices, and fastening the data exchange between the components of radio engineering complexes. In this case, one of the relevant issues is the development of frequency-selective devices operating in the microwave frequency range. A promising line for the creation of such devices is their integrated design based on a volumetric strip-slot transition. This article presents theoretical and experimental research of the s-parameters of the volumetric strip-slot transition. The frequency-selective properties of the volumetric strip-slot transition were estimated based on the obtained dependences of the s-parameters. The theoretical results were obtained by creating a matrix mathematical model, by designing an equivalent circuit in a circuit-simulation program, and by the numerical simulation based on solving a boundary value problem in a strict diffraction statement, using direct numerical methods. The experimental results were obtained using a sample of the volumetric strip-slot transition. The presented results of the three types of simulation and the experimental results are in good numerical relation to each other.

Authors: Bamatov D M , Bamatov I M , Arsanov M M
Published: November 2020

The aim of the work was to see if the direction of angular momenta in atoms is quantised. In order to do it, a beam of atoms is split, and deflected because of interactions between atomic dipole moments and an externally applied magnetic field. In which case, the angular momenta in atoms is definitively quantised. Firstly, the detector was checked and then the operation of the detector was characterised; secondly, the beam was detected and characterised with residual magnetisation minimised; thirdly, the beam was detected and characterised with magnetic field present. The sample used to determine the magnetic moment was Potassium. The Bohr’s magneton constant value was found to be (9.22±0.7)*10−24 J/T. The answer is lower than the nominal value but lies within the expected error range. This proved the accuracy of the work done and proved the quantisation of the angular momentum, since it proved the presence of magnetic moment.

Authors: Simunin M M
Published: November 2020

The state of the field of technologies for the synthesis of carbon nanotubes today allows the production of large volumes of nanotubes with desired properties, however, issues related to their application, as a rule, face difficulties that often require the process to be specialized. This work can help to form approaches to solving possible difficulties in the methods of using carbon nanotubes. The presented technological concept makes it possible to obtain both carbon nanotubes and graphene in a single-type installation from different carbon-containing sources. Using the oxidation of a carbon source, reduce the temperature of synthesis from it to the temperatures of synthesis from carbon monoxide, as well as get rid of excess amorphous phases formed during pyrolysis. Finally, it is precisely the positioning of the catalyst in the right places, without the possibility of its surface diffusion and evaporation, which will make it possible to obtain functional elements based on carbon nanotubes or graphene in these regions.

Published: November 2020

We investigate the electron spin resonance of an ensemble of Nitrogen-Vacancy color centers in a bulk diamond crystal obtained by CVD-method. The diamond crystal had 1 ppm concentration of nitrogen. The four possible orientations of the NV-center in the crystal lattice lead to different dependences of a magnitude and an orientation of the external static magnetic field. We used the field of 35 Gauss with the vector in the plane of the crystal. We could rotate it to a certain angle within almost 360 degrees around the normal vector to the plane of the crystal. The goal was to define the unknown orientations of the four axes of the NV-centers relatively to the crystal plane. Experimental results obtained at room temperature with a continuous microwave excitation and presented in this paper are in a good agreement with our simulations.

Features of carbon layers synthesis on the porous anodic alumina
Authors: Simunin M M
Published: November 2020

Carbon nanotubes and graphene are two of the most important forms of nanoscale carbon materials. Both materials can be synthesized by CVD method with the use of various “catalysts”. The term “catalyst” is conditional; it refers to a surface, on which graphite islands are formed at a relatively low temperature. Either carbon nanotubes or graphene layers can grow on the surface depending on its shape and physical-chemical properties. As a rule, the materials of such surfaces are the most common metals of auxiliary groups [1], in which the carbon is dissolved after chemical deposition from the gas phase. Then, as a result of supersaturation of carbon solution in metal, the carbon precipitates on the surface in the form of graphite islands, which combine into graphene or nanotubes. However, the ordered carbon structures can be obtained not only by dissolving carbon in metals, but also by using special surfaces, where the surface diffusion of carbon can occur. Aluminum oxide provides an example of such material.

Published: November 2020

The problems of ensuring safety in the process of fulfilling technical regulations on railway transport at the stop points of tanks with oil products are stated. A basic list of polluting components discharged into the air at the parking of railway tank cars is presented, while priority pollutants are identified. The components that determine the pollution of the railway parking area have been regulated, and the gross emissions have been quantitatively established. The practical implementation of the protection of the air environment of the city of Voronezh is proposed, which implies the removal of stopping points of railway rolling stock, realizing the transit of oil and oil products, outside the residential zone of an industrial city with a million population. This applies to the points of technical stopping of railway tank cars with oil products, both short-term and long-term deployment. It is shown that the inspection and control of specific tank washing points is coordinated by the safety data sheet of the facility itself, which should be included in the category of potentially hazardous facilities.

The changes that have occurred in the business landscape due to COVID-19 present marketologists and entrepreneurs with new problems. The forced trend of a sharp increase in online interaction with consumers should be used. Such global shifts give rise to innovative tools for evaluating commercial results and transform old techniques to correspond to the new reality of the market. This is the basic condition for a business to sustain in any industry. This paper focuses on developing a theoretical description of the multi-stage interaction with the customer base. In order to solve this problem, a mathematical model was developed at the base of which is a digital information interaction, starting with identifying the target audience and finishing with a completed commercial transaction. Unlike the classical sales funnel, the algorithms presented allow a multi-dimensional conversion funnel to be used for more than just evaluating the results of business for the accounting period. Thanks to a stream of arguments for the model in real time, it is becoming possible to optimize the commercial process by moving to the concept of leading economic indicators.

Bellman’s method allows increasing the increase in the value of the objective function over 5 years by 85% from the initial value with a decrease in the distributed resource by 20%. It is believed that the construction of railways leads to an increase in gross regional product by 2%, but the authors proved that it is possible to increase this figure to 7-8%

In this paper, the most important aspect is touched upon - the principle of constructing an individual learning path in the system of open education. At the moment, there is no clear implemented construction method that satisfies both the learner and the teacher. The method proposed in this paper is based on the use of neural network technologies to determine significant input parameters that affect the success rate. At the first stage of determining an individual trajectory, proceeding mainly from theoretical ideas about the diagnosed set, a “draft” version of the list of parameters is formed. This option includes parameters that, according to the expert, should reflect the individual psychological differences of the subjects. The definition of a “draft” version of the initial set of diagnostic features is a difficult formalized task.

Published: November 2020

The purpose of the work is to study the subject matter and application of infological models and substantiate the definition of the infological model concept. The article contains a short literature review of the use of such term as ‘infological model’. The concepts and viewpoints of the interpretation of this concept are analysed in the article. The article reveals the cognitive factor of the infological model. Many researchers have not considered this factor. The article proves that a cognitive map is the most striking representation of the infological model. The article proves that there is no need to associate the infological model with databases only and to identify it with the entity-relationship model. Based on the research carried out, a new definition of the infological model has been formulated.

The authors analyze the results of tree taxation of different apple trees varieties on the territory of I V Budagovsky research and development center at Michurinsk State Agrarian University. The plantation valuation and the establishment of locality class were carried out using the methodology of Michurinsk State Agrarian University. Studies have shown that class quality of the garden can be characterized as high – from 85 to 100 points, which corresponds to the first class of quality. Thus, all graft-rootstock combinations are normally developed, while it was found that within the studied population for a number of graft-rootstock combinations the percentage of normally developed trees is on the verge of transition to a lower quality class. The authors proposed a method for developing a program to automatically determine the state of each tree based on using digital recognition technology, the proposed technology will significantly reduce time and labor costs and exclude the subjective assessment factor.

Resource management in client-server computing systems based on trust assessment
Authors: Lebedev R V , Murigin A V , Tynchenko V S
Published: November 2020

The article describes a trust assessment model and a method based on it for managing client access to scarce resources in a client-server computing system. Trust in a client is the degree to which it meets the standard. The trust assessment score is based on an ordinal preference scale with a limited normalized weight of criteria. The model allows you to get a numerical assessment of the client’s compliance with a given set of criteria. The method of managing computer system resources is based on a controlled impact on the communication channel between the client and the server of the system. This method describes how to select a threshold value for the trust assessment score. The method allows you to reasonably limit the total number of clients in the system and thereby increase the probability of access to scarce computing resources of the server for trusted clients.
Synthesis of parameterized families of correctly functioning sigma-pi neurons
Authors: Shibzukhov Z M
Published: November 2020

The ΣΠ-neuron is a biologically inspired formal model for logical information processing. The ΣΠ-neuron model adequately reflects information processing processes in the cerebral cortex and in the dendritic trees of neurons. The advantage of the ΣΠ-neuron model is the ability to accurately represent any Boolean function and the possibility of constructive learning (direct construction) in a single pass of the training sample. Another possibility is the direct construction of an ensemble of ΣΠ-neurons that function correctly on the training sample. This article discusses a new algorithm for constructing such ensemble of ΣΠ-neurons in parameterized form. This form can also be easily represented as a single ΣΠ-neuron with a hidden layer of linear and threshold linear units. In some cases, this makes it easier to retrain on new inputs by setting the appropriate control parameter values.
The problem of the optimal timing of equipment change taking into account the life cycle of information resources

Published: November 2020

The paper solves the problem of the optimal timing of equipment change in the process of capacity management, taking into account the life cycle of information resources. A simple method for determining the optimal timing for replacing equipment intended for storing and processing information resources is proposed. The purpose of this task is to compare the residual value of equipment in operation and the cost of using it. Since the cost of equipment falls over time, and the cost of operating it increases, there is a moment in time when the costs begin to exceed the residual value of the equipment, and this moment is considered optimal for the transition to new, more productive equipment. This problem is considered in relation to data storage systems, which are currently implemented mainly in the form of disk systems, but the method used is universal. The method is illustrated by a numerical example for one of the IT organizations. Recommendations for servicing disk storage systems are given. Further prospects for the development of this problem with the improvement of the methodology are outlined.
