Objectives. This article explores in detail questions of instrument operation function of tapping internal threads in hard materials. The existing relationship between vibration system amplitude and tool durability is indicated; on this basis, it is determined that the best course for improving the durability performance is increasing vibratory resistance. Based on a critical analysis of existing designs with consideration of their flaws, the development of new technological designs of taps is tasked with ensuring stable operation when handling hard materials. Methods. It is noteworthy that one of the main vibration resistance improvement methods of the tool is to reduce the contact area of the tool with the work piece in the cutting zone. Methods are proposed for improving the vibration resistance of taps, considering the correlation adjustment of tap teeth in order to completely eliminate friction at the sides of the thread cutting surface and uneven implementation flute cutting steps. Results. The idea of increasing vibration resistance has seen the new development of vibration-proof tap designs, heralded as innovations due to the accuracy of thread cutting and durability achieved by reducing the thread contact area with the work piece in the cutting zone. Increased vibration resistance is achieved in the modified taps through high correction by means of thread side downgrading of the coarse tap cone by an additional angle of 30º. In another design, the stylus provided with uneven angular spacing. Test results of designed taps machined in corrosion-resistant 1Kh18N9T steel. A manifold increase in tool durability was achieved due to its high vibration resistance. Conclusions. The redesigned taps have a number of advantages, characterised by a high resistance when processing difficult materials and an insignificant increase in the complexity of their manufacture compared with standard taps. Therefore they can be recommended for large-scale implementation in production. 

Objectives. To investigate the increased performance possibilities of screws on submersible pumps by vibratory finishing of their surfaces. Method. The vibratory finishing method is based on two principles: rejection of light plastic deformation polishing as well as the complication of kinematics associated with known cold working processes. Results. A schematic diagram of vibratory finishing; the compiled graphs show pressure, occurring in the surface layer of steel 30KhGSA when lathe turning and vibratory finishing; the microhardness dependence on the work hardening distribution depth at rolling and vibratory finishing is determined. It is established that since vibratory finishing is a method of hardening, kinematic and dynamic characteristics of the process are connected, as in other types of finishing, with characteristic indicators of machined surfaces. The task of developing methods for determining the vibratory finishing regime is complicated, firstly by the number of parameters that determine the process conditions being considerably greater than tumbling and other processing methods with relatively simple kinematics; secondly, due to the fact that all the mode parameters affect all surface quality characteristics in one way or another. Conclusion. When vibratory finishing the surface layer of a screw submerged in a vibratory machine, using steel shots for burnishing, an extension of the surface layer's elastic-plastic deformation to a certain depth is achieved. The temperature at the time of vibratory finishing, according to conventional standards, does not exceed 150-300OC; moreover, it decreases sharply with increasing depth and at room temperature is already at the depth of 0.1-0.3 mm from the surface of the screw. Microrelief optimisation of the bearing surfaces is the most effective way to improve conformability, reduce the run-in and normal wear and improve anti-seize properties.The efficiency and potential for the use of vibratory finishing in virtually all areas of the metal industry is proven.

Objectives. To evaluate the correspondence of construction and power consumption of Cryotherapeutic Complexes (CTC) with technological conditions of effectiveness of the General Cryotherapeutic Impact (GCI). Methods. The associated analysis method used Cryotherapeutic Complexes (CTC) construction and power consumption with technological conditions of effectiveness of the General Cryotherapeutic Impact (GCI). Results. An explanation for the discrepancy of observations of different researchers in differences in design and available power of the CTC is proposed. The technical operating characteristics of single-seat and multi-seat CTC are provided and these significant differences in apparatus of identical technological designation are illustrated. The proposed system of specific CTC characteristics is capable of unifying their basic structural and energy characteristics. Calculation of the specific characteristics of existing systems showed that between objects of the same designation, there are differences in value, which may be the cause of discrepancies in their therapeutic efficacy. All functional CPC have a cryostatting cooling capacity system deficit of between 8 and 75%. In multi-seat CPC cooling capacity deficit exceeds 50%, which excludes the possibility of obtaining a significant therapeutic effect, as is confirmed by the results of independent studies that show that the procedures in multi-seat CTC safeguards skin from frigorism only up to 14°C, while at the same time for effective OKV frigorism of the skin surface is necessary to a temperature of less than about 2°C. Prior to research on the effectiveness of OKV, it is necessary to assess the energy consumption conformity of cryotherapy equipment. Conclusion. For the successful implementation of OKV in medicine and sport, it is necessary to increase energy efficiency and optimise cryotherapeutic temperature control settings. A cryotheraputic complex should safeguard such physical conditions in such a way that the body surface is frigerised to a temperature of less than about 2°C. The cryostatting patient cabin system cooling capacity should provide heat removal from the surface of the patient's skin with an intensity of no lower than 3.35 kW/m². For intensive heat removal from the patient's body surface the cooling gas temperature must not exceed -130ºC. 

Objectives. The purpose of the study is to provide an improved multiphase flow meter that meets the metrological and technical standards, the composition of which would exclude radioactive elements. Method. Instead of gamma radiation, the optoacoustic effect is proposed for use in the multiphase flow meter. The table shows the plan of the flow meter with a description of its assembly. The possibilities of using the optoacoustic effect for creating ultrasonic multiphase flow meter with high power emitters are also considered. Results. An analysis of modern multiphase flow meters, including the most popular, which utilise a nozzle within the design of the Venturi meter gamma densitometer. The advantages and disadvantages of the multiphase flow meters. Instead of the gamma ray method the use of the optical-acoustic effect is proposed. During laser irradiation of the medium, pressure wave were formed. Judging on the basis of pressure readings, the parameters of the medium can evaluated: optical density, medium density. Conclusion. The main requirement for a multi-phase flow meter is to achieve precision oil level readings during transport. Multiphase flow meters allow the principle implementation of the separate developed measure registering the quantity of produced gas-liquid mixture during the satellite fields development and wells belonging to different owners, i.e. offering a significant economic effect. It is evident that the multiphase flow meter will play a key role in optimising production control in oil and gas fields. It is necessary to continue research through series of experiments in order to verify the metrological characteristics and implementation possibilities of the technology. 

Objectives. The aim of this work is to develop a mathematical tool for describing the scattering of radio signals by meteor trails associated with radio wave dispersion taking into account a range of extenuatory factors. Method The study was carried out using mathematical analysis in the application of meteorite radio wave reflection theory. Results The questions of the scattering of radio waves from undercompacted and overcompacted meteor trails, as measured by radio sounding in a continuous pulse mode, are considered separately. The mechanisms that influence the formation of the amplitude of the RF signal reflected from a meteor trail are discussed in detail. The obtained mathematical expressions enable the initial reflected signal amplitudes from undercompacted and overcompacted meteor trails to be evaluated for power capacity in the different operation modes of radio transmitting stations. Conclusion Following from the theory of the scattering of radiowaves by meteor trails, it is shown that the radiolocation calculation method for sounding meteor trails coincides with the existing theory. The results of the study may be useful for further development of transverse meteor wave propagation theory, especially for the theory of amplitude distribution reflection response.The results may also be used to describe transverse scattering of meteorite trails, as well as for radiolocalisation of meteor trails in both modes. 

Objectives. A method for diagnosing electronic components with minimally complicated control and measuring instrumentation and the ability to obtain information from internal control points of operating units is developed. Methods. The developed method for control of groups of electronic components presupposes the passage of a controllable influence through a few control points, connected via several electronic components. In addition, each electronic component contributes its share to the transformation of the parameter output, so the discrepancy of its allowable values for the identification of defective electronic component are required to assess the implication of the expected value of the probable defect of each electronic component in the schema with the aim of isolating it. The faulty component in the electronic circuit is identified by the minimum estimated variance, by which the magnitude of the defect will match the expected value of the electronic component parameter. Results. As a result of the control no more than ten groups of electrical components on functional cell matrices can be assessed as having a defective element by comparing the calculated variance values for each electrical component and the corresponding electrical component parameter itself. Conclusion. Diagnosing groups of electric components on transient characteristics for the detection of defects in the functional cell matrices enables efficiency control operations improvement and troubleshooting in the search for modern electronic equipment reliability. 

Objectives. The present article is based on the examination of the causes of thermodynamic heat loss in thermoelectric heat transformers. It is shown that the external loss in a real system is comparable to the internal loss in thermoelements at the present stage of thermoelectric engineering instrument development. External technical losses are attributed to the irreversibility of processes in system elements. These are determined by their technical resolution and can be lowered by means of specific approaches to design and construction. Methods. Examples of effective technical solutions for thermoelectric units of the "air-to-air" and "air-to-liquid" types, in which external losses are minimised due to the application of heat exchangers based on two-phase thermosyphons of special configuration, are given. For air coolers with a classic all-metal fin design based on the sensitivity analysis method, the dependence of the thermoelectric unit efficiency on the heat exchanger characteristics was calculated. Results. As a result, calculations of the dependence of cooling unit refrigeration capacity on the energy transformation ratio, power transfer coefficient, energy conversion efficiency (ECE) and the relative energetic efficiency of ECE were performed based on the characteristic of the heat exchanger air passage geometry. There is a dependence relationship between the thermoelectric conversion cooling unit refrigeration capacity and transformation ratio within the function of material and thickness of the ribs on the intercostal distance and on the height of the air heat exchanger channel. Conclusion. Examples of the proposed effective thermal circuit technical solutions are based on thermoelectricheat transformers with heat flow direction change and with heat exchangers, which are based on two-phase thermosyphons. Classical solutions of all-metal heat exchangers can also be optimised on the basis of the sensitivity analysis methodology. 

Objectives. To determine the coordinates of the seismic focus of an earthquake with a minimum margin of error with the use of an optimal selection of seismic sensors. Method. Seismic wave velocity data, relying on the time discrepancies between the registering of seismic waves on the seismic sensor and the defined error in determining the time difference, were used to identify errors in the location of an earthquake's hypocenter depending on the respective positions of three seismic sensors. Discrepancies between data containing an error and those without it used to determine two hypocenters provide information about the hypocenter locating error. An analysis of the influence of the respective arrangements of the seismic sensors and the earthquake epicentre on the accuracy of determination of epicentre coordinates was carried out. Results. It is established that, in order to improve the accuracy of epicenter and hypocenter earthquake coordinate determination, it is preferable to use different combinations of seismic sensors. The present recommendations are based on the desire to reduce errors in determining the earthquake source coordinates. Due to earthquake epicenter distance determination errors found in different seismic sensors both with increasing and decreasing distance, the hypocenter coordinate determining error has been found to depend on the respective arrangement of seismic sensors and on the earthquake source's geographical location. In order to determine the dependence of the source coordinate determining error on the relative position of three seismic sensors, the third seismic sensor was displaced on a horizontal plane at the location centered at the coordinate of the origin. Conclusion. When selecting seismic sensors it is essential that one of them be located perpendicular to the center of the segment formed by the other two seismic sensors. The probability of a multidirectional error of measurement at the moment of arrival of seismic wave is higher the closer the seismic sensors are to one another; this is due to the fact that seismic waves pass close by the trajectory layout.

Objectives. A mathematical modeling method is used to describe the process of resorption and salt depletion by filtration through fractured gypsified rock strata.Since the increase in the opening of crevasses due to resorption of their walls from water percolating through rock fractures containing soluble contaminants, a change in the porosity and fracturing of rocks increases filtration rate and Darcy flux leading to foundation subsidence. Method. A process for the simplest schema with a single particulate material filling a fissure of length l and width 2h is examined; the filtration rate is considered constant and equal to v. To solve the resulting parabolic equation the economical difference scheme of alternating directions (convergence formula) is used; this is totally stable and requires simultaneous linear algebraic equations (SLAE) equations with a tridiagonal matrix at each stage of the solution. Results. An algorithm, compiled and programmed to calculate the distribution of concentrations in the fissure using DELPHI programming language, is proposed. Numerical results are summarised due to dissolution concentration distinction in the filled fissure. Conclusion. Using a modified algorithm, the compiled and debugged program using DELPHI programming language allows the distribution of concentrations to be calculated. 

Objectives. The aim of the work is to solve reliability problems associated with the improvement of neural linear homogeneous media by means of the sliding structural redundancy method. Method. In the course of the studythe most effective method of ensuring product reliability structural redundancy, while in the structure of the product, along with the ―basic‖ elements, additional elements are included, which substitute for the function in cases where others have failed. Results. It is proposed that functional models of media elements be oriented towards the presence of their internal redunant elements; on the basis of the established functional dependence of the number of external redundant elements with the number of internal redundant elements, we calculated the reliability of redundant media, thus confirming reliability improvement. A comparative analysis of the existing functional element and their development is presented. A reliability calculation for homogeneous linear neural environments both with and without the presence of redundant components clearly demonstrates the numerous advantage of homogeneous linear neural environments with redundant elements. The necessity of the information exchange of connections among the elements of the environment when changing the redundancy ratio are also shown. Conclusion. The approach proposes to improve the reliability of media using elements which have existing connections with numerous other elements in the media, using ―informational redundancy‖ and the redundant elements within the structure, enabling the creation of homogeneous high reliability media with the possibility of ―information control‖. The proposed element enables the construction of media providing the ability to ―control‖ two failed elements, which implies the presence in the environment of two redundant elements that can be replaced in the case of the failure of any pair of key elements. 

Objectives. The presented research problem concerns data regularities for an unspecified time series based on an approach to the expert formalisation of knowledge integrated into a decision-making mechanism. Method. A context-free grammar, consisting of a modification of universal temporal grammar, is used to describe regularities. Using the rules of the developed grammar, an expert can describe patterns in the group of time series. A multi-dimensional matrix pattern of the behaviour of a group of time series is used in a real-time decision-making regime in the expert system to implements a universal approach to the description of the dynamics of these changes in the expert system. The multidimensional matrix pattern is specifically intended for decision-making in an expert system; the modified temporal grammar is used to identify patterns in the data. Results. It is proposed to use the temporal relations of the series and fix observation values in the time interval as ―From-To‖, ―Before‖, ―After‖, ―Simultaneously‖ and ―Duration‖. A syntactically oriented converter of descriptions is developed. A schema for the creation and application of matrix patterns in expert systems is drawn up. Conclusion. The advantage of the implementation of the proposed hybrid approaches consists in a reduction of the time taken for identifying temporal patterns and an automation of the matrix pattern of the decision-making system based on expert descriptions verified using live data derived from relationships in the monitoring data. 

Objectives. This article considers issues involved in the development and continued improvement of computing methods for the study of the causes of landslides. Methods .The existing deterministic assessment approach to stability assessment contains an element of uncertainty. A mass stability forecast, accomplished by means of a complex account of the impact on the variation of its input parameters generally on the basis of modelled random variables, or, in cases where information on the status of the massif at different times is present, a random function model, is proposed. The use of the random function model when solving the problem of forecasting the stability of the massif enables the evaluation of such important parameters of the safe development of the landslide process as probability of occurrence, i.e. the decrease below the permissible level of the safety coefficient, and the time period of development, so as to maintain the safety status of the massif.A method for determining the cost of maintaining the necessary stability or reliability coefficient value at a time when their calculated values are less than the respective permissible values is shown. Results. The implementation of measures to ensure the stability of the ground massif are associated with certain costs, and, in the case of a landslide, with additional losses incurred as a consequence. The cost of activities and the likelihood of loss are functional stability factors. The arrived-at expression determines the optimal massif stability coefficient value, which will correspond with the minimum total cost of the exercise and with additional losses in the event of a landslide. Conclusion.The calculations have shown that the stability of a massif and safety parameters (loss of stability in the absence of time and probability) depend on the structure and characteristics of the constituent rocks of the massif. 

Objectives. Experimental and theoretical determination of dependencies of strength characteristics of bored micropiles with a pedestal formed by rammed rubble on: casing diameter, fraction, and volume of crushed stone for collapsing macroporous clays. Method. Laboratory and field experiments were carried out; numerical calculations in two-dimensional and threedimensional arrangement for the determination of strain-stress analysis of the foundation using a MIDAS GTS_NX software system, implementing the finite element method and developed for complex geotechnical problems; some recommendations for implementation are provided. Results The dependence of the load-bearing capacity of bored micropiles on a broadened base of rammed aggregate with vertical loading is determined. At the maximum broadening diameter of 3.5 of the micropiles shaft the load-bearing capacity of the subsoil is increased by between 1.8 and 6 times compared with micropiles without broadening depending on the diameter of the pile shaft. During the experimental and numerical studies of the dependencies of deformation-strength parameters of the deep foundation works consisting of a bored micropile with a broadened base, namely the pile diameter, aggregate particle size and volume, seal diameter of the subsoil soil half-space, as well as the development of the theory of formation of the end broadening geometry of rammed aggregate in the form of an ellipsoid of revolution were established. Conclusion The full-scale measurements of the broadening of bored micropiles showed that their shape is close to an ellipsoid of revolution, and the ratio of semi-axes is directly dependent on the characteristics of soil and gravel volume, which was taken into account in the construction of the finite element model in the numerical simulation experiment.The results of numerical studies of the bored micropile loading with broadened base on the MIDAS GTS show good agreement with the results of the field test, consisting of a difference of between 2 and 15%. 

Objectives. The development of high-strength concrete based on experience both with domestic and foreign concretes has led to the production of a self-consolidating concrete (SCC) formula. Method. Raw materials sourced from the Chechen Republic were used in the SUBconcrete formula, based on materials having different classes of compressive strength as well as the incorporation of polycarboxylate as an additive. Results. An investigation was carried out on natural and technogenic raw materials from the Chechen Republic and other regions of the country. Compositions of high-grade SCC with a compressive strength of B100 and higher are achieved with an integrated approach using both natural and man-made raw materials. The formulae of the basic concrete reinforcing technology are examined together with their physico-mechanical properties. The results of the study of locally sourced concrete, as well as that purchased from "Pavlovskgranit" and OOO "Progress" for testing from the Republic of North Ossetia–Alania, are provided. Of the various manufacturers' cements investigated, the highest quality Portland cement CEM I 4.5N was selected from the Tula cement manufacturers in the town of Chiri-Yurt. The fillers used were microsilica sourced from the Novokuznetsk plant, inactivated MP-1 mineral powder produced in Kaluga and fly ash sourced from Nevinnomyssk. Conclusion. The results of the studies show that the raw material potential of our country allows for the production of self-consolidating concrete from class B 25 to B100 and higher for use in monolithic construction, including high-rise. The concrete compositions arrived at are characterised by their high physical and mechanical properties and can be used in high-rise concrete construction sites operating in earthquake-prone areas. 

Objectives. The aim of this study consists ina parametric analysis of the stress state of transversely isotropic rocky ground in the vicinity of a circular cross-sectional hydraulic tunnel taking into account the dead load of the subsoil medium under various relations of the elastic characteristics of the subsoil environment in orthogonal directions and at different angles of inclination of the plane of isotropy. Methods. A transversely isotropic medium model (a special case of an anisotropic medium) is applied, in which the subsoil in one plane has the characteristics of an isotropic medium (isotropic plane) but in a perpendicular direction – in contradistinction to the characteristics of an isotropic medium.The angle of isotropic planar inclination models the oblique bedding of subsoil layers. Results. The determination of tangential stresses on the contour generation allows the strength of the subsoil medium to be estimated at different depths of emplacement. The calculation of extensive hydraulic engineering tunnels, constructed in strong, transversely isotropic rocky ground, is reduced to a problem of plane strain elasticity theory for a transversely isotropic medium surrounding the tunnel construction. Since the solution of this problem cannot be achieved using analytical methods, the analysis of the stress state was carried out by finite element method using the ANSYS software complex. The type and size of the finite element appropriate for the calculation were pre-identified based on solutions to the task of verification. For the verificatory task, the Kirsch problem was adopted. Conclusion.When designing underground structures, it is necessary to determine the physical and mechanical properties of rocky soils in greater detail and to pay special attention to the elastic characteristics. The absence of tensile stresses in the upper section of development with some relations of the moduli of deformation and Poisson's ratios benefit the work of hydraulic tunnelling. At a bedding angle of at least 30º, its impact on the state of stress is insignificant and calculations can be carried out without taking the angle into account, but instead considering the anisotropy of the elastic properties. 

Objectives. The formation of the structure of hardened concrete grouting with two-stage expansion is a complex process that is influenced by many factors, both of a prescriptive nature (composition and additive dosage, mineralogical composition of Portland cement clinker, concrete composition, the presence of chemical additives) and in terms of process (the fineness of cement grinding, temperature of curing, etc.). Methods. In order to assess the impact of the above factors, the article proposes the introduction of a number of integrated indicators being characterised as a process in which influences are shown alongside the factor generating the influence. For the evaluation of the influence of different factors on the process of gas generation, an effectiveness ratio of gas generation is proposed by the authors. Results. The article presents the results of an investigation into the influence of the amount of gassing agent and the type and dosage of superplasticiser on the process of gassing by means of the displacement method on the mortar mix. The authors similarly propose a expansion efficiency coefficient. The article presents the results of the investigation into the influence of the amount of gassing agent, the presence and amount of superplasticiser, the sand/cement ratio, aggregate size and water-cement ratio during the first stage of expansion of the mixture. The authors propose a formula for describing the dependence of the relative expansion deformations on the concentration of filler. In order to assess the conditions in which a mixture is present, it is proposed to use an indicator consisting in the constraint expansion coefficient. Conclusion. Use of the hardening condition coefficient is proposed as a means of accounting for the effect of curing conditions on the strength of the concrete grouting with two-stage expansion. The authors recommend taking the introduction of correction factors into account when considering the impact of formulation and technological factors.

Objectives. Due to the issue of public utility development becoming a key concern for many Russian municipalities, this study aims to evaluate methods for increasing the efficiency of municipal services. The reason for this is the severe dilapidation of the physical infrastructure. Given the limited budget, the question inevitably arises as to how to most effectively spend the funds available and at the same time solve emerging urban infrastructure problems. Method. Use of the municipal-private partnership mechanism can significantly reduce the burden on the municipal budget.The method of paired comparisons of alternative models is recommended on the basis of the choice of the municipal-private partnership model.Alternative models of municipal-private partnership are ranked in preference against a plurality of predetermined comparison criteria. Results.The results of an analysis of the development of municipal services in the city of Makhachkala are presented. The necessity for municipal-private partnerships to be developed in the area of urban public utilities is substantiated. A structural-logical model of municipal-private partnership in the communal area of the city is proposed with the concrete functions assigned to each of the members of the municipal-private partnership. Conclusion. It is demonstrated that municipal-private partnerships serve as a means of optimising the performance of municipal functions with respect to the seamless provision of quality housing and communal services to the city's population and creation of a favourable urban environment. Use of the proposed method allows alternative models to be evaluated and the optimal model of municipal-private partnership selected for the implementation of a specific project in the area of urban public utilities. 

Objectives. In the article, the problem of the optimisation of the energy modernisation of residential housing is examined. Methods. A mathematical model for the optimisation of energy use is developed with the use of dynamic programming techniques. Results. The proposed method of assessing the effectiveness of comprehensive energy-saving measures can improve the quality of decision-making on housing recovery and increase its energy modernisation. The application of mathematical modeling allows for the distribution of funds to projects so that the implementation of organisational and technological solutions consistently implement measures that will lead to optimal social and economic effects. The developed mathematical model also allows the amount of quality housing to be maximised through the implementation of energy-saving and other measures when upgrading the housing stock. Problems concerning the renovation of housing stock are analysed. The concept of housing energy modernisation is introduced.

It is assumed that the optimal solution is obtained independently of the number of steps and the initial supply of invested capital.Conclusion. The energy modernisation of the housing stock leads to a reduction in the expenditures of citizens on housing and utilities services, contributing to an increase in the integral index of comfort. A generalised method for optimal control of the housing stock is implemented on the basis of the provided schema for dynamic scheduling of the optimal distribution of funds for energy-saving measures. 

Objectives. Innovative activity is a key factor in the effective development and growth of competitiveness in the Russian economy. An important role in this process is played by industrial corporations. Against this background, there is an increased need for improving the effectiveness of methods for evaluating the innovation development of Russian corporations. Methods. Formal logic as well as system analysis methods were used in the research, allowing us to consider the corporation as a system that includes a variety of innovational directions (elements). Results. The article discusses various approaches to the determination of the basic definitions of innovation; a classification of innovation is proposed. The attributes of innovative activity of industrial corporations are distinguished together with an outline of the possible causes of various innovative corporate activities; components of the system of indicators of innovation activity are isolated: financial; consumer; process; development and training; risk management. The need for the indices of the innovation activity of the risk component to be included in the composition of the system is substantiated. It is shown how the objectives for each area of innovation may be achieved in tandem with a methodological approach that allows continuous monitoring of the implementation of innovative development strategies. An algorithm for evaluating the implementation of innovative strategies contributing to the development of industrial corporations is presented. Conclusion. Theoretical and methodological development can be used not only to navigate the variety of innovations but also to determine and establish the relationship and interdependence between the various innovations as well as carry out analysis, assessment and forecasting for the effective development of innovative activity of Russian corporations.
