Application of the probability changing method for optimal location problems on a network

Antamoshkin A.N., Kazakovtsev L.A.

Abstract

In this paper, the authors consider the p-median optimal location problem on a graph (network) which is a popular model for both logistic problems (optimal transportation, telecommunication and other infrastructure elements placement) and problems of cluster analysis, pattern recognition and estimation theory. The aim of the p-median problem on a graph (network) is to find the given number p of vertices of a graph such that the total distance from each vertex to the nearest chosen vertex reaches its minimum. To solve this NP-hard (in general) problem approximately, the authors propose a heuristic algorithm based on ideas of the probability changing method which is a random search method with adaptation. The idea of the proposed algorithm is based on random choosing of vertices in accordance with the given probabilities of choosing each of them. The probabilities for every chosen vertex and its neighborhood alter depending on the value of the objective function (i.e. in accordance with the total distance from each of the vertices to the nearest chosen vertex). For the algorithm for the large-scale p-median problems, a problem of optimal use of computational capacity is important. The effectiveness of the proposed algorithm was proved experimentally on test datasets from the ORLIB (special dataset library for operations research). In addition, the authors illustrate the results for the proposed algorithm combined with a local search procedure for the considered problem. The experiments show that the results of such combination exceed the results of the multiple start of the local search procedure from randomly chosen vertices. In addition, the experiments demonstrate the ability of the proposed algorithm to reach an exact solution for small problems.

The selection of logical patterns for constructing a decision rule of recognition

Antamoshkin A.N., Masich I.S.

Abstract

We investigate an aspect of the construction of logical recognition algorithms - selection of patterns in the set of found patterns in the data. We consider the recognition problem for objects described by binary attributes and divided into two classes. In consequence of performance the procedure of searching patterns on the training set (a set of input data) a number of patterns has been found. The question is to select some patterns from their total number to form a decision rule. That can not only reduce the size of the decision rule, but also improve recognition. One way to make a selection of patterns is to select a subset of patterns that is needed to cover all objects of the training sample. This problem is formulated as an optimization problem. The resulting optimization model represents a problem of conditional pseudo-Boolean optimization, in which the objective function and the constraints functions are unimodal monotone pseudo-Boolean functions. Another way is to make the selection of such patterns, which when used together will increase separating capacity of the decision rule. As a criterion for the formation of the decision rule is considered the width of the separation margin. One more way is to select supporting objects and on their basis to form the rules. The selection of logical patterns, which is made in accordance with the proposed approach, can significantly reduce the number of patterns and simplify the decision rule, almost without compromising the accuracy of recognition. This makes the decision rule clearer, and the results more interpretable. It is necessary to support decision making for recognition.

About the control of objects with the memory in a nonparametric uncertainty

Bannikova A.V., Medvedev A.V.

Abstract

We consider the problem of identification and control of stochastic objects with discrete - continuous nature of the process. In this paper, we study more general class of dynamic objects in the future - objects with memory. The characteristic distinguishing feature of these processes is the fact that in the description the difference analogues of differential equations, taken in the classical theory of identification and control, are not used. The similar processes occur in many different kennels control of aerospace technology. For example, when vibration testing spacecraft channel “vibrator-sensor mounted on the spacecraft” can be described by difference equations. In this case, the lack of natural analogy between the equation in continuous time and difference is typical. This feature is the main difference with memory objects from the traditional dynamic processes. It leaves its mark in the modeling and management of such objects, and determines the urgency of the problem. This article discusses theoretical information about nonparametric algorithms of identification and control. Non-parametric model for objects with memory addresses are considered in two embodiments. One of them is closely related with the description of the object as the Duhamel integral. The second way is partial parameterization of the object, that is, to meet the conditions of both parametric and non-parametric uncertainties. The constructing nonparametric algorithms of dual control are based on the idea of A. A. Feldbaum. It states that the input object “on” its inverse counterpart, the language of mathematicians its inverse. Obviously, the description may not be accurate for some reasons, and then the inverse operator can only approximately describe the process in the direction of “exit-entry”. On this basis, both non-parametric models of objects with memory and nonparametric algorithms of dual control are lined up. The learning system of dual control with active accumulation of information is carefully analyzed. The detailed results of the numerical investigation of non-parametric models for multivariate processes with memory, as well as the results of numerical experiments applying the algorithm of nonparametric adaptive dual control are given.

Person identification by signature in the electronic document management system

Baranov R.P.

Abstract

This report deals with the approach to the problem of human identification by signature. It is described how to identify person's signature, depending on the source from which the signature was obtained. A method for pre-processing the image signature is considered. An example of the method signature of the cashier in the image obtained from a photograph of the check is shown. The of-line signature verification is demanded in business and marketing, bank transactions, security control, and document authentication. The off-line signature verification is the difficult process against the on-line verification. In this paper, the extension offeature set, including global, local, and special features for simple and cursive types of signatures, is proposed. The global features are required to create a decision tree, which limits a field of the search. In this report, an approach for a human identification by person signature is considered. The methods of signature identification dependently from a way, how this signature was received, are described. A preprocessing of an image improves the following identification results. The implementation of Distance Transform algorithm describing the various metrics is shown. An approach for calculating the graphical representation of the signature characteristics, based on the calculation of the distance matrix is given. The benefits of the proposed algorithm for calculating the characteristics over the classic algorithm are described. An algorithm of comparing signature graphic characteristics using the metric SSIM is shown. Testing algorithm for human identification signature using different image quality and size is conducted. The results of testing the algorithm are shown. The software system for a person’s identification by a signature is developed.

Effective speech-based student authentication procedure in distance learning

Brester C.Y., Vishnevskaya S.R., Semenkina O.E., Sidorov M.Y.

Abstract

Nowadays it is almost impossible to find a university that does not provide its students with online courses or correspondence education. Due to various advantages, distance learning has attracted more and more people in recent years. As a result, some of the requirements that this educational format has to satisfy have been included in legislation systems. The necessity to authenticate students remotely is presented as a compulsory procedure in many official documents. When teachers are deprived of face-to-face contact with their students, there is a need to find an appropriate way to verify their personality distantly. In this paper we propose the speech-based student authentication procedure which operates with some acoustic characteristics extracted from voice signals. However, there is one crucial question related to the classification model providing high performance. It is almost impossible for the online systems to vary classifiers and determine the most effective one while interacting with a user. Therefore, to increase the reliability of our proposal we elaborated some classification schemes based on collective decision making to take into account predictions of different classifiers. To prove the effectiveness of this approach, we used a number of multi-lingual corpora (German, English, Japanese). According to the results obtained, a high level of speaker recognition was achieved (up to 100 % of F-score values). The developed algorithmic schemes provide a guaranteed level of effectiveness and might be used as a reliable alternative to the occasional choice of a classification model.

Modeling of complex processes using autoregressive methods

Gorodov A.A., Gorodova L.V., Kuznetsov A.A.

Abstract

We reviewed the use of numerical series to estimate the parameters in the autoregressive model in this paper. A method and the basic procedure for determining the order of autoregressive model and the choice of a numerical series are described. The purpose of this work is the generalization of the obtained results, identifying characteristics of the autoregressive when modeling complex processes and simplified procedures for the selection of parameters is based on the use of numerical series. The basic theoretical and practical results are obtained on the basis of methodology of system analysis, the theory of random processes, information technologies and methods of fundamental and applied mathematics. We compared the method of numerical series with known methods ofparameter estimation in autoregressive models. It is shown the relationship between the autoregressive models and classical mathematical concepts such as the ‘golden section’, ‘Pascal's triangle ’, the Fibonacci numbers and the Tribonacci numbers. Also we gave estimates for autoregressive models for long-term forecasting. It is shown the relationship between the fourth-order autoregressive with the series of the Kvadrobonacci numbers. We summarized the known recommendations on the application of numerical series. These recommendations help to simplify the procedure for selection of numerical series and improve the quality of the model. For short and medium-term forecasts with a constant average it is recommended to use coefficients which are calculated using the Fibonacci and the Tribonacci series. The obtained results will be useful in modeling of complex processes with a time component.

Algorithms of Wiener system identification

Koplyarova N.V.

Abstract

This article is devoted to the problem of identification of nonlinear dynamic systems Wiener class under conditions of incomplete information. It is now widely known parametric identification methods such systems, which often have a discretecontinuous. Normally, when a parametric formulation of the problem identification class of equations describing the dynamic process is known up to a vector of parameters. The next stage is the estimation of parameters from observations of “input-output" process variables. It is important to note that the choice of the parametric model structure of the object is extremely important. Model inaccuracies arising from some errors at the stage of its parametric selection or definition, can not be rectified in the evaluation parameters. This means that the model is in one sense or another, quite rough. In this paper, the linear element model Wiener is not known with an accuracy of parameters, which corresponds to the non-parametric uncertainty. As a non-linear element model is adopted one or other parametric structure. Specifically, we consider the case when the parameter block is represented as a quad and a saturation level. Thus, the problem of identification of objects of a class of stochastic Wiener is seen in partial non-parametric uncertainty. At the first stage model of linear dynamic block is built. To construct a non-parametric model of the last input object must submit the Heaviside function, in this case, the output of the object to within a factor is its transition function. Reconstruction of the weight function is carried out by the observations of transitional methods of nonparametric statistics. To estimate the parameters of non-linear element is necessary to conduct appropriate experiments. We should pay particular attention to the fact that in the identification of nonlinear dynamic system Wiener class, subject only to the control input and output variables. This situation is typical not only in the manufacture of spacecraft, but many of their units and components. Furthermore, these models are useful in creating computer systems of technical diagnostics with vibration testing of spacecraft (SC) on the channel: Vibrate - sensor mounted on the spacecraft. A numerical study of the proposed algorithms, consider the model of the class of Wiener in different conditions (at different levels of noise in the measurement channels, a different sample size and types of input actions). The results of computer studies show efficiency of the proposed algorithms.

Krasnov I.Z.

Abstract

In modern business environment the role of effective governance on the basis of reliable information increases many times is very important. Error management based on insufficient or incorrectly interpreted data, can lead to the collapse of even a large company. Modern, complex and dynamic market environment requires from Russian companies continuous improvement of their management systems and information systems support. One of the main directions of creation of effective system of enterprise management is the application of the process approach to organization and management. Information becomes the most powerful tool in the hands of the manager. Effective management is impossible without information gathering and processing by various methods. The methods of obtaining information are diverse and are not considered in this work. The methods of the targeted distribution of information on the recipients were much more interesting, which is reflected in this work. In this work the author considers a problem of management of access to information resources of the enterprises. The purposes of a control system of access are formulated. Interrelation of the purposes of information security and available threats of safety is defined. It is suggested to use an access matrix as a passive element ofprotection of information resources. The tasks which need to be solved in any control system of access are formulates. A task of an exception of redundancy when carrying out measures ofprotection of information resources is set. A technique offormation of a matrix of access is offered. The procedure of categorization of information, identification of groups of risk, formation ofprofiles of access, fixing of access rights in regulating documents of the organization is described.

Hybrid evolutionary algorithm for automated design of decision trees

Lipinskiy L.V., Kushnareva T.V., Dyabkin E.V., Popov E.A.

Abstract

Issues related to the design and training of decision trees, are considered in the paper. Problems of decision trees over-fitting are discussed as well as their ability to the generalization. Questions of local search procedures for the adjustment of decision trees are described. An evolutionary approach to the automated design of decision trees is suggested based on a hybridization of the genetic programming and genetic algorithm. Genetic programming fulfills the search of effective structures in the space of decision trees. Genetic programming is searching for effective variant of decision trees functional nodes position and interconnections, i.e. a structure. The tree structure is built with elements of terminal and functional sets of genetic programming. Elements of the functional set are conditions which limited one of input variables and divided original data set into subgroups. Elements of the terminal set are possible decisions which should be made within solving a problem in hand. Genetic algorithm solves the problem of parameters optimization. Each condition within a decision tree has one or more parameters which are coded into binary string. Genetic algorithm seeks parameters which minimize an error of the decision tree on the instances of the training sample. In the article, the framework of the joint execution of genetic programming and genetic algorithm is given and main evolutionary operators are considered. Suggested approach was implemented as a computing system that allows designing binary decision trees with one parameter nodes. Operation windows of the implemented computing system are presented. The problem of diagnosing the severity of injuries of the abdominal cavity with peritonitis has been solved with the use of developed approach. It was demonstrated that the evolutionary techniques based on the hybridization of the genetic programming and the genetic algorithm allow automated designing decision trees with the high ability to generalization which use four times less information comparing to data usually collected in a patient anamnesis.

Development of recursive generative grammars system for solving the problem of automatic generation of language phrases intonation patterns

Lichargin D.V., Trushakova A.I., Safonov K.V., Bachurina E.P.

Abstract

This paper considers the problem of developing a new class of generative grammars, providing higher quality of string generation and internal order of the rules. The purpose is to justify theoretically and to develop the module in the previously developed system for automatic generation of transcription in various European languages, which allows adding the intonation patterns, which will enable the student to study the language, its phonetic structure and features in a more effective way. In addition, it is important to solve the problem of modality identification, the distinction between narrative sentences, questions and exclamations that will provide an opportunity to speak and express many types of emotions in a foreign language without preliminary knowledge of words and rules. This type of generative grammars - “recursive generative grammars ” - should allow solving a wider class of problems through the use of dividing the entire class of rules within generative grammars to levels and sections, what will be demonstrated in the structure of the relevant rules. Methods to accomplish the above purpose consist in hybridization of generative grammar and substring of command in the form of nonterminals of generative grammar. As a result of work a principle organizing a set of trees of the states of generated string expressions in the natural language has been developed. The developed approach allows the implementation of the algorithms for generating the strings of the natural language from concerning the application of nonterminal characters of generative grammars. The proposed approach to extending the syntax of the generative grammar rules can allow providing a more complex and qualitative transformation of generated string of the characters alphabet considering the structuring process for the trees of states on the levels of recursive generation. These tools of computational linguistics can be applied as the means of modeling and analyzing the natural languages, in particular, in order to generate meaningful speech and carry out language transformations. This will allow solving more complex problems in computational linguistics and the development of linguistic software.

About a Sylow 2-subgroup in the periodic group with a given set of finite subgroups

Pronina E.A., Shlepkin A.A., Darziev A.N.

Abstract

This article is about the study of infinite groups with different conditions limbs actual problem in group theory. One of such conditions is the condition of saturation of a group specified set of groups. The group G is full of groups of many M, if any finite subset of is contained in a subgroup G isomorphic to some group of M . It is known that an arbitrary periodic group, saturated groups from a variety of groups |l 2(p n)}, where p and n not fixed, is isomorphic to L 2(Q), where Q is a locally - finite field. Additionally, this result has been generalized to the case when the group is saturated with groups from a variety ofgroups {>SL 2 (p n)}. It would be natural to consider the case when periodic group are saturated with groups from a variety of groups |GL 2( p n)} : Let a periodic group G is saturated with many groups {gL 2 (p n)}, where p, n not fixed. Then G - GL 2 (Q) for some locally finite fields Q . Thus, there is a problem of separation in periodic groups of classes of groups in which this hypothesis holds. This hypothesis is proved in the class of locally _ finite groups. One of the classes in which this hypothesis may be true, is the class of groups Shunkov. In this class, this hypothesis was proved for periodic groups Shunkov when the additional constraint is fixed p. Attempt to abandon the fixity conditions led to the need for classification of Sylow 2-subgroups in these groups. In this work, this classification is made. The structure of Sylow 2-subgroups of the group G for the case when is M of the full linear group of degree two over finite fields.

Video-based smoke detection using local binary patterns

Pyataeva A.V.

Abstract

Smoke detection is particularly important for early warning systems because smoke usually rises before flames arise. Video surveillance systems are widely applied in a variety of fields such as urban scenes and forest scenes. Hence, video-based smoke detection is regarded as an effective and inexpensive way for fire detection in an open space. The existing methods can be classified as histogram-based detection, methods of temporal analysis, smoke detection based on heuristic rules, and hybrid methods. This paper presents an automatic smoke detection method using computer vision and pattern recognition techniques. The method involves texture analysis with rotation and illumination invariant local binary pattern, local ternary pattern, and extended local binary pattern. The novel Local Binary Patterns (LBPs) called as Temporal LBPs were developed. Temporal LBPs are built as 3D structure based on neighbor frames for analysis of dynamic textures. For smoke verification, two different classes of histogram are computed. As a measure of the differences for smoke and non-smoke histograms, Kullback-Leibler Divergence was used. Experiments on the Dyntex database illustrate the effectiveness of the proposed method. Numerical results were obtained by using various types of known LBP for semi-transparent and opaque smoke. The set of all samples was divided in training set (80 %) and testing set (20 %o). Experiments show the advantages of 3D Temporal LBPs against classical 2D LBPs for dynamic fast changed textures. Experimental results show that the proposed method is feasible and effective for videobased smoke classification at interactive frame rates.

Computer security problems solving by automatically designed neural network ensembles

Semenkina M.E., Popov E.A.

Abstract

Today, computers are becoming more powerful and interconnected that makes their security one of the most important concerns. Conventional security software requires a lot of human effort to identify and work out threats. This human labor intensive process can be more efficient by applying machine learning algorithms. Artificial neural networks are one of the most widely used data mining techniques here. The highly increasing computing power and technology made possible the use of more complex intelligent architectures, taking advantage of more than one intelligent system in a collaborative way. This is an effective combination of intelligent techniques that outperforms or competes to simple standard intelligent techniques. One of the hybridization forms, the ensemble technique, has been applied in many real world problems. In this paper, artificial neural networks based ensembles are used for solving the computer security problems. We apply the self-configuring genetic programming technique to construct symbolic regression formula that shows how to compute an ensemble decision using the component ANN decisions. The algorithm involves different operations and math functions and uses the models providing the diversity among the ensemble members. Namely, we use neural networks, automatically designed with our GP algorithm, as the ensemble members. The algorithm automatically chooses component ANNs which are important for obtaining an efficient solution and doesn ’t use the others. Performance of the approach is demonstrated with test problems and then applied to two real world problems from the field of computer security - intrusion and spam detection. The proposed approach demonstrates results competitive to known techniques. With the approach developed an end user has no necessity to be an expert in the computational intelligence area but can implement the reliable and effective data mining tool.

Self-configuring hybrid evolutionary algorithm for fuzzy classifier design with active learning for unbalanced datasets

Stanovov V.V., Semenkina O.E.

Abstract

The paper describes an active training example selection for a self-configured hybrid evolutionary algorithm for fuzzy rule bases design for classification problems. This method is related to instance selection methods, which allow not only decreasing of required computational recourses, but also increasing the quality of the obtained classifiers. The method changes the probabilities of instances which are selected into the training subsample depending on how good they are classified by the algorithm. After several generations the sample is changed and probabilities are recalculated. Those instances which were not used before and those which were misclassified by the algorithm had higher probabilities of getting into the training sample. The probabilities of instance selection were calculated using a procedure similar to proportional selection in the genetic algorithm. The idea of training instance selection described here was implemented for the fuzzy classifiers forming. This algorithm uses the combination of Pittsburg and Michigan approach for fuzzy rule base design with fixed terms, and the Michigan approach is used together with the mutation operator. The size of the rule base is not fixed, and may change during the algorithm run, and a corresponding class number and the rule weight were calculated heuristically for every rule. Moreover, the algorithm uses an initialization procedure that uses instances from the sample to generate more accurate rules. In the Michigan part the operators of adding rules, deleting rules and replacing rules has been implemented. The creation of new rules could be performed by genetic approach - using the existing rules, and heuristically - using those instances which were misclassified. The efficiency of the algorithm was shown on a set of complex classification problems with several classes, as an efficiency measure the overall accuracy and the average accuracy among classes was used.

Remote sensing for reconstruction of natural landscape scenes

Tkacheva A.A.

Abstract

In this paper we are going to build the three-dimensional model of the natural scene based on laser scanning data. The complex requirements of plant modeling applications are nowadays supported by high end GIS and remote sensing data gathering methods such as RADAR, LiDAR DTM and DSM data, high resolution satellite data, stereo camera images etc., as well as automated draping technologies for 3D objects. These technologies allow the creation of synthetic and photorealistic 3D landscape visualizations and simulations to display planning alternatives, scenarios and depict clearly their impact on landscape scenery. It is a task that affects both computer graphics and computer vision. The reconstruction of landscape scenes based on the original point clouds from laser scanners is divided into the following subtasks: association of input data into a single coordinate system, LIDAR data classification for reconstruction natural landscape scenes, 3d landscape modeling (the surface of the Еarth), and plant modeling (trees and shrubs). We pose the problem of classification of the original point cloud with LIDAR into three categories: trees and shrubs (woodland), the surface of the ground and other objects (anthropological objects). Highlight one spatial attribute E (x), according to which we will refer to the terms of this or that category. In this work, we present an adaptation of L-systems and Space Colonization algorithm to the Python language, a popular and powerful open-license dynamic language. Visualization of the script is executed by standard tools of the graphical editor Blender. We show that the use of dynamic language properties makes it possible to build complex models.

Abstract

The analysis of a design modern current collection devices used in space equipment is presented in the article. The main objective of this work is determination of the constructive methods and receptions that improve the output characteristics of the current collection device, preserving the reliability of functioning of the device throughout all term of active existence of the spacecraft in an orbit. The role of the current collection device in a spaceship power supply system is considered; the basic constructive elements of the device are described; the principles offunctioning of the device are stated. The main output characteristics of the current collection device - value of the voltage drop across the layer of the collector rings and the total power disseminated on the device are defined. The factors affecting described output parameters - change the actual contact area between the collector rings one kinematic contact pairs, the penetration of particles of dielectric material on the contact surface of the collector rings, the formation of non-conductive films. It shows the influence of axial and radial instability clips collector rings on the actual contact area of collector rings one kinematic contact pair, are stated. The reasons for the formation ofparticles of the dielectric material during operation of the device, formation of a film of dielectric material on the contact surface of the collector rings are described. The influence of the total radial bias force on the deformation of the contact rings one kinematic contact pair is considered. The relation between the cyclic loading of the outer collector rings and wave-like change of the moment of rotation of the output shaft of the device is determined. An experiment on the effects offluctuations in the torque of rotation of the output shaft of the device on the value of the voltage drop at the collector rings in a single layer is presented and described. The authors conclude that smoothing the peaks of the twisting moment will provide smoother and stable characteristic changes of the voltage drop across the collector layer of the rings, to reduce the average value of the voltage drop on each layer of the collector rings and, therefore, reduce the total power dissipated on the current collection device. It is suggested to include solutions to achieve axial and radial stability clips of current collector rings in the operation of the device in the future construction of current collection devices.

Improvement of the positioning accuracy along the joint connection of details with the residual magnetization in electron beam welding

Druzhinina A.A., Laptenok V.D., Murygin A.V.

Abstract

The effect of residual magnetization of the welded parts on the accuracy positioning of the electron beam along the joint connection is a complicated scientific and technical problem to achieve the high quality of welded joints in the aerospace industry, shipbuilding and power engineering. As a result of analysis of the magnetic fields of residual magnetization the authors obtained the mathematical model of their distribution in the space between the electron beam gun and the workpiece and also the quantitative characteristics of deflection of the electron beam from the joint connection were obtained. For obtaining the mathematical model, the authors use a method which is widely known in the literature. This method is based on the representation of residual magnetization as equivalent field of conductor with current. Comparative evaluation of experimental and calculated data confirms the adequacy of the modeling. The authors have developed a method and a functional diagram of the automatic compensation of the effect of magnetic fields on the accuracy of positioning of the electron beam along the joint connection in the process of electron beam welding. The system of automatic compensation includes a collimated X-ray sensor, which is designed for monitoring deflection of the electron beam from the optical axis of the electron beam gun. The X-ray sensor is placed on the electron beam gun. The collimation slit of X-ray sensor is aimed at the optical axis of the gun. The method of synchronous detection is used to process information from the X-ray sensor. Thus the signals of the first and second harmonics of the scanning frequency of the electron beam across the joint connection are allocated. The method of synchronous detection uses the technological scanning of electron beam across and along the joint connection. The technological scanning allows to provide the measurement of deflection of the electron beam and to expand opportunities to improve weld quality by controlling the distribution of energy in the heating spot. Automatic compensation of the action of magnetic fields of residual magnetization of welded product can reduce the positioning error of the electron beam on the joint connection in the weld root in 20-30 times.

Corrosion resistance MAO coatings on titanium alloy

Ravodina D.V., Trushkina T.V., Miheev A.E., Girn A.V., Khomenko I.I.

Abstract

One of the promising materials used in various fields of technology, is titanium and its alloys. This is due to its favorable combination of physical and chemical properties and improved corrosion resistance to the atmospheric conditions. However, in certain corrosive media, especially in the presence of abrasion, titanium and its alloys is the subject to corrosive degradation. The electroplating method used currently to improve the corrosion resistance of metals, has several disadvantages: low ecological safety of the process associated with aggressive electrolytes used, the need for additional operations washing, degreasing, etching, strict observance of the temperature regime during processing. The resulting coatings electroplated not meet the requirements for corrosion resistance in corrosive environments, especially in the presence of abrasive wear. The paper proposes a method for improving the corrosion resistance of titanium and its alloys in corrosive environments, especially in the presence of abrasion, the metal coating on the surface of the protective layer microarc oxidation. The studies of morphology, chemical composition and thickness of the coatings were conducted. These studies have shown that in the MAO coating not only the phase y-TiO 2 is formed, but also the phase a-TiO 2, which is a major contributor to the hardened layer. Hardening of microarc oxidation during metals due to the formation on the surface coating which consists of titanium oxide and oxides of chemical elements contained in the electrolyte composition. Accelerated Laboratory Test corrosion resistance coatings showed that the coatings have MAO higher corrosion resistance as compared to coatings deposited by galvanic anodizing. Samples treated in silicate-alkaline electrolyte have the highest corrosion resistance. Process conditions for applying a corrosion resistant coating on titanium and its alloys are defined.

Taxation polysystemic monopolies

Bubnov V.A., Khaustov D.S., Khomenko G.A.

Abstract

International financial sanctions imposed against our country in 2014, and outlined the recession put before the Russian economic science, the problem of finding ways of further development of the country. Infrastructure projects, as international experience shows, has always been a powerful tool to stimulate economic growth. For the Russian Federation - the largest country in the world is the greatest relevance transport infrastructure, in which JSC “Russian Railways” play a decisive role. Rail transport, since its inception, has traditionally been a powerful engine of social and economic development of the country. Russian system of taxation of corporations is defined in separate articles of the Tax Code, which makes it difficult to understand the impact of taxes on the financial and economic results of their activities. As statistics show, large corporations are taxpayers, form the basic income of the consolidated federal budget. Individual corporations can be attributed to polysystemic monopolies, including JSC “Russian Railways”. Polysystemic monopolies have a significant multiplier effect for economic growth and development. Consequently, the tax policy in respect thereof shall be taken into account these features. Implemented analysis allows a comprehensive look at tax policy of the Russian state in relation to the largest corporations, which has obviously expressed fiscal nature. In resulting in the withdrawal offinancial resources in central government funds to the detriment of corporate finance. There is a tendency of decrease in investment activity on the part of big business. This applies to both traditional infrastructure and knowledge-based - aerospace. This has led to a significant reduction in the rate of economic growth for the period 2011-2014 year, and in 2015-2016 is expected recession. Worded provisions allow the use offiscal policy for the expanded reproduction through the use of potential polysystemic monopolies. This could have a significant multiplicative effect on the Russian economy, which ultimately will contribute to accelerate the pace of socio-economic development of our country and the growth of tax revenues at all levels of the budget and state funds.

Abstract

In the time of economic model changes the regional economic systems’ (RES) internal transformation flatness increases inevitably, the contradictions between supply and demand on the local markets become sharper, that reduces to structural misbalance’ increase and RES stability decrease. The most part of the problems numbered is specified by contemporary economic development peculiarities: spatial type of placement, technologically heterogeneous economy and trade irregularity of the innovation development, in consequence of which the needs of economic players are various in different sectors. As the result, the tasks ofproviding conditions for existing competitive products and traditional economic resources, stable work of the market, and new innovation products and new quality of resources markets formation as well come into existence. This period offeatures investigation allowed scrutinizing RES’ firmness as the aptitude for persistent increase of socio-economic development indicators in the terms of resources usage efficiency rise, and also as the facility for retention of target trajectory of development in terms of structural changes in the regional economic sections. The existence of cause-and-effect relations between the development processes in the market reproduction subsystem of the region and the economic growth effects uncover the local market role (elements of the market subsystem, structural factors of growth, economic development indicators) and the various aspects of impact on the RES’ firmness, make possible to use the local markets to manage RES stability. The systemic type of local market influence on the regional economic stability is substantiated in the article. The necessity of two groups of conditions forming is determined. These two groups consist of indispensable and sufficient factors for achievement of regional development effects in the regional economic segments and provide balanced changes in the local market system.

Role of innovative small enterprises in modern economy

Erygina L.V., Orlova K.V.

Abstract

Small business corresponds to inquiries practically of all areas of economy of the Russian Federation and meets the requirements of the world economic processes. Small business gives freedom of a business choice and induces the effective organization ofproduction. These qualities of small business do it to one of the main components of market economy. In some countries with the developed market economy the volume ofproduction of small enterprises exceeds a half of gross domestic product. Small business not only makes an essential contribution to gross domestic product, but also influences the general growth of economy. Thanks to small business the competition role in economy raises, market needs for goods and services are more stoutly satisfied, market niches at all levels - from local to regional are filled. Small enterprises give additional workplaces, master local raw material resources, the worthy wage level expands a consumer sector. These factors positively influence the social sphere; defuse social tension, participations in business activity, creation offamily business, realization of creative potential give opportunity. Small business is effective in the consumer sphere, production of details and knots which production the large enterprises consider unprofitable. Efficiency of small enterprises is shown in development of resource-saving technologies, in the sphere of development of software products. Small business is capable to cooperate successfully with the enterprises of the space-rocket industry in programs of conversion. The small innovative enterprises carry out commercialization of the scientific development which isn’t demanding big investments and attraction of essential material, labor and energy resources. The federal Program of the state support of small business in the Russian Federation considers development of small business in the country as one of the major tasks at the state level.

Abstract

This article describes the features of Adaptive planning production program of defense industry enterprises in which the central management are planning the assortment policy. The purpose of this study is to support the concept of “Adaptive planning of the production program of the enterprise". As a result of the analysis of kinship terms, identifying key, defined author's position. The definition of Adaptive planning of the production program of enterprise, taking into account the diversity of approaches to understand the concepts and basic principles of planning is proposed. Due to the ambiguity of interpretation principles reflecting enterprise production program planning for Adaptive planning, clarified and supplemented by the principles of planning. These principles are determined by relevance, adaptability, dynamic and uncertain factors of internal and external environment, as well as the need to ensure sustainable development of the enterprise. A qualified content submitted principle involves mandatory uncertainty, continuous adjustment, correction and clarification of the plans, the ability to change its focus in response to unexpected changes of internal and external nature. The pressing challenge of approaches for a reasonable compromise between the costs of the implementation of the planning process and achieved the effect is solved. The directions to reduce the level of uncertainty and corporate planning and commercial and financial stability are shown: the use of more complex approaches and methods, including the theory of decision-making under uncertainty, proposes the introduction of a system ofplanning, responsive to changing economic conditions. With the introduction of Adaptive planning it is proposed to monitor the structure and volume of demand within a timeout period that allows moving the production program to meet changed conditions. The solution to this problem proposed by developing techniques for the planning of the production program of the adaptive enterprise.

On forecasting economic indexes by means of neuroevolutionary models

Fedotov D.V., Semenkin E.S.

Abstract

Time series prediction is quite complex and interesting problem. Usually a forecast is based on information from the past, i.e. on previous values offeatures. The economic situation in the country depends on different factors and events and influences many situations. The innovation projects in aerospace field require a large amount of investments and take a long time for development and implementation. These kinds of investments require relevant and reliable information about possible future economic situation to minimize risks and correct the plans in right time. In particular, to get such information one may use the time series of the various indexes of economic development. In this paper, the neural network predictors are used as the main technology offorecasting. They are generated automatically by means of genetic algorithms that allow increasing the quality of the prediction. Besides, the advantages of the use of selfconfiguring genetic algorithms in comparison with standard genetic algorithms are demonstrated when adjusting the weighting coefficients of the neural network. The quality of the solution provided by the neural network depends also on its structure. In this paper, the genetic programming is used for the neural network structure design due to its ability to provide effective and flexible models without a human expert. This allows automating the neural network based predictors configuring. The combination of these intellectual information technologies is tested on the financial time series forecasting task using the values of the prices and volumes along with the technical indicators as the inputs. The developed system allows automated designing the neural network based predictors and getting a high quality forecast of economic indexes changes. The developed system shows better results in the comparison with the other forecasting technologies.

On the one hand, the features of the present stage of regional development caused the economic transition to the innovative model and the changes of internal business processes, on the other hand - it is because of the influence of globalization factors in the terms of the national economy sociability. These features cause the need to transform the system of local markets to ensure the sustainability of the regional economic system. The orientation of the regional economy on the technological innovation leads to the transformation of supply and demand parameters on the final markets and resources due to the change of business entities needs. The spatial character of the regional economy distribution, technological stratification and sectorial variation of innovative development make the necessary to provide simultaneous formation of local markets of innovative products and sustainable functioning of markets of traditional products and resources. However, there are different methods of local markets research, focused, mainly, on the separate development of certain types of markets, those avoid the need to explain their relationships and influence on the structural transformation of the regional economy. In addition, local markets traditionally regarded as subsystems of the territorial sphere of commodity circulation in the context of scientific research. However, in the context of the patency of national economy the regional local markets acquire new properties and qualities; those allow to use their capacity to ensure the sustainability of the regional economic system in the transition to an innovative model of development. The narrowing of difference between supply and demand parameters, arising between the periods of occurrence and satisfaction of innovation needs becomes executable. The article reviewed the specify conception of local market, analyzing the system of relationships between market agents with respect to the harmonization and implementation of economic interests. The conception explains additional characteristics of local markets - regional utility and multi-pronged effect on the innovative development of the region. Local criteria and strategy-preserving utility function are proposed. Also, the article shows the systemic nature of influence of local markets on the regional economic system balance and the conditions offormation of innovative potential of the region.
