Feasibility review of substitution a high-lift device by a telescopic wing with self-similarity of reynolds
Authors: Bobkov A , Mitashova T
Published: October 2020

This Paper describes results of the feasibility review of a telescopic wing application in unmanned aerial systems with self-similarity of Reynolds Re. Low Re is achieved through low-velocity flow of the lifting surface and small dimensions of an aircraft. Such combination is typical for a mini remotely piloted system according to UVS International classification. At low Reynolds the wing lift and high-lift device performance reduce. While in the high-lift mode, it is possible to adjust the wing area rather than the lift ratio. This can be achieved by a telescopic wing consisting of fixed and retractable sections. A telescopic wing is based on Morphing design with simultaneous wing geometry adapting to current flight parameters in one, two or three planes. The wing is simple by the design and can function as a high-lift device or aileron depending on whether the sections move out at the same time. The area of a telescopic wing with its sections moving out in the high-lift mode needs to be 2.0…2.18 times greater the initial area for Reynolds variation (2.7…4)⋅105.

Authors: Kryuchkov S V , Malinin V G , Bogdanov N P , Konovalov M N , Malukhina O A
Published: October 2020

An experimental method was obtained for treating semi-finished products from titanium nickelide alloys TN-1 by twisting a cylindrical sample in the austenitic state at a temperature of T = 493 K to a predetermined angular strain, after which the sample was rigidly clamped, fixing the angular deformation of the sample, and cooled to a temperature of T = 293 K. At a given temperature, the rigid jamming of the sample is eliminated, while the isothermal return of the part of the deformation obtained by twisting in the austenitic state occurs. Then the sample is heated to a temperature of T = 493 K, and there is a shape memory effect (SME), manifested in the form of restoration of angular deformation. A systematic experimental study was carried out of the dependence of the influence of the complex regime of thermal-mechanical action containing the stages of generation and relaxation of stresses on the shape memory effect. It has been experimentally established that SME during heating after cooling in the direct MT range under pinched conditions can be observed with zero deformation effect in the final heating interval.

Improving cyber security is the purpose of all states. Military-industrial complex is in need of creating innovative protection systems for their cyber space. A lack of such security systems can lead to the global disaster, using nuclear weapons. Today’s legal regulation of the national personal data still does not provide for legal regulation of user data which can be obtained via gadgets fitted with cameras, speakers, applications. Apart from information leakage as a result of hacker attacks, and accidental cyber leaks, the great problem is related to unlawful leakage and data stolen by company employees. Although the legislation of personal data protection is improving with allowance for precedents in this sphere leading to cybercrimes, an amount of unlawful use of personal data by company employees do not decrease due to a lack of accountability and behavior code in the sphere of personal data processing.

Authors: Tanina Anna , Kalmykova Svetlana , Zaborovskaia Olga
Published: October 2020

Digitalization of tourism in the Russian Federation is primarily associated with the increasing importance of tourism, not only as a way to spend leisure time, but also as a branch of the economy that can generate a significant income and ensure territorial development. Despite a large number of diverse tourism resources in the country, tourism development was highly uneven, concentrating in a limited number of regions.

Information technology and especially the Internet has greatly toughened global competition over tourist flows. In today’s world, tourists would rather visit a place about which they can get sufficient information and where a trip can be easily arranged. The role of national and regional tourist web portals, supported by relevant government agencies, is significantly increasing in this context. The tourist information infrastructure should not only provide up-to-date and complete information, but also ensure usability for the tourist (including independent). Tourism within St. Petersburg and Leningrad Region is featured by rather close links between the regions and unification of tourist flows between them. Both regions have a significant quantity of tourist resources, which ensures development of various types of tourism. Creation of the ‘silver Necklace’ interregional route consolidated further integration between tourist resources of the neighboring regions. Tourist portals of these regions, nevertheless, significantly differ in their content and interactive capabilities. As part of the study, the information presented on tourist portals of Russia, St. Petersburg and Leningrad Region in terms of implementing interactive services was reviewed.
The Formation of Partnership Model in Supply Chain Management
Authors: Suvorova Svetlana , Tevanyan Anna
Published: October 2020

Supply chain management is a complex and systematic process of moving commodity flows from the moment of production planning to the further distribution of products in accordance with the market conditions and the target segment requirements. Meanwhile, the effectiveness of the supply chain can be achieved through the formation of partnerships that are aimed at organizing comprehensive cooperation of economic entities with its inalienable integration into the logistics chain of their own production. Also, such partnerships are based on the desire of economic entities to concentrate the required resources in the area of the irown competence, whereas to delegate the other functions to the third-party enterprises (for example, outsourcing them). In order to establish a partnership, the parties involved must determine and agree on possible motivators, contributing factors, business process components and expected results, taking into account the balance of power, specialization, readiness for cooperation of stakeholders, possible damage and distribution of risks, importance of the applicant, reasons for withdrawal from the contract and “force majeure” circumstances. This proposed model of partnership in supply chain management allows reducing the production cycle, the maintenance costs and the “money-money” cycle. It also allows improving the performance of the supply chain, optimizing logistics costs, which, in turn, creates favorable conditions for reducing foreign economic costs, increasing profits and focusing the core competencies of the enterprise-manufacturer.

The growth of market competition, its transition to regional and international levels, the development of information technologies as well as dramatic changes in consumer behaviour determine the development of global market trends, which necessitates the study of a methodology to form distribution channels, from the viewpoint of digital connectivity and transition to a more complex global system. The paper discusses the conceptual framework for creating a digital business ecosystem as a combination of three components: the consumer’s ecosystem, the producer’s ecosystem and the communicative connecting core. The object of research is a distribution system that operates in a market environment. The research is based on the application of the descriptive-analytical and comparative methods as well as the method of semantic and structural analysis, the method of monitoring the content of terminology in theoretical and applied papers within the chosen field of study. Significant development trends have been identified in the theory of global value chains and supply chains, the strategic goal of which is not to dominate, but to keep the balance that generates added value. The ecosystem formation theory terminology is enriched by introducing the concept of “a digital ecosystem” into the scientific circulation. The role of the consumer as a full participant in the business ecosystem, who is engaged in the process of creating additional consumer value, is determined.

Authors: Khareva Viktoria , Voronova Olga , Khnykina Tatyana
Published: October 2020

The article presents the development of a reference model for the “Purchase” business process as an element of modeling the basic business processes at FMCG chain retailing companies. In many ways, the rationale for the development of a business architecture model is related to the understanding of factors that push chain companies to search optimization solutions in terms of organizing their work. In these conditions, modeling basic business processes of the company is essential for the construction of architectural solutions of FMCG retail network companies. The models are based on a hierarchical principle that allows to consistently move to the next level of detail, as long as the model is not described in as much detail as necessary to solve specific problems of FMCG chain retailing companies. In accordance with the aim of the study, the basic business processes of FMCG-retail network companies are identified, a typical structure of the “Purchase” business process is presented, a contextual chart of the top level of detail and a subsidiary model of the “Purchase” business process are consistently developed (the IDEF0 notation is used in this study). On the basis of top-level models, models of subprocesses of business process A1 “Purchase” are developed: A1. 1 “Purchasing planning”; A1. 2 “Choice of Suppliers; A1. 3 “Conclusion of the Contract with Supplier”; A1. 4 “Operational management of Deliveries”; And 1.5 “Assessment of suppliers”. The developed models can be used in construction of architectural solutions in FMCG chain retailing companies.

In this paper, we study the trends of investment attractiveness of trade in Russia, connected with unfavorable social and economic factors of recent times, are studied. The analysis shows that despite its high practical significance, the concept of an “innovation and investment project” does not have a commonly accepted scientific definition. There is neither a unified approach to understanding this term, nor a holistic view of the problems and tasks that need to be addressed during the implementation of such projects. An analysis of the concept of an “innovation and investment project” has made it possible to identify the shortcomings in the existing interpretations and to propose a new one. Based on the analysis of systems for innovation and investment project management, we identify the advantages and disadvantages of these systems, and propose a model for a basic system for innovation and investment project management, including: principles, methods, tools for its implementation.

It is established that the nature of the distribution of micronutrients is determined by their biological role. The elements are part of enzymes: manganese, iron and zinc prevail in the nucleus. Phosphorus, potassium, magnesium are found in greater quantity in the vital layer of aleurone. Cobalt, nickel, aluminum, calcium, chromium, copper, selenium and cadmium dominate the grain surface. The largest amount of mineral elements in the grain is concentrated in the seed. The distribution of metals in triticale grains is characterized by characteristic patterns of wheat and rye. In the distribution of mineral elements in wheat, rye and triticale grains, differences are observed, which are explained by the specific characteristics of these plants. From the grain studied, cereal bread was prepared unmatched on a thick grain leaven. The analysis of the mineral content of the grain bread showed that it was enriched with all major biogenic mineral elements and contained toxic metals (lead and cadmium) in a quantity not exceeding the CMP. A strong negative correlation has been established between levels of certain biological and toxic elements in grain and in pain. The revealed relationship indicates the possibility of switching from dispersive X-ray spectroscopy in a scanning electron microscope system to predict the quality and safety of grain pain, particularly for predicting of the content heavy metals in finished bakery products.

The development of product formulations for the nutrition of young children is a complex and laborious task, the solution of which involves the calculation of the nutritional value of both individual components and the whole product. The article shows a step-by-step way of solving a particular example of designing a product recipe for feeding young children using the standard add-on “Solution Finder” of the Microsoft Excel spreadsheet processor. A special place in the article is given to the formation of a table with the source data. Uncertain factors in the calculation of the formulation are the mass fractions of the raw materials, which should be determined taking into account the objective function and a number of restrictions. Restrictions on the ratio of proteins, fats, carbohydrates and water were used as the main parameters for optimizing the formulations for the nutrition of young children, and the cost of the finished product was determined as a function of the goal. As a result of using the Microsoft Excel spreadsheet editor, the formula for the baby food with the specified properties was calculated taking into account the installed food components of the mixture, a number of limiting factors and the low cost of the finished product, equal to 98.9 RUB per 1 kg which corresponds to 1.4 Euro per 1 kg at the current exchange rate.

The article reviews the methods of end-to-end automation of business processes and the basic architecture of telecom operator systems. Nowadays, the main goal of any telecom operator is to minimize manual operations at all stages of the company’s operations: from receiving the order for the service to its full activation. However, today any telecom operator already has the necessary infrastructure to carry out its activities. This leads to two possible automation methods: sequential updating of existing system or full “end-to-end” automation. The authors analyze the basic modules of the telecom operator’s system and conclude that it is a complex multi-module system. The authors compare the automation methods and justify that full “end-to-end” automation the most profitable automation method in case the telecom operator has decided to completely upgrade all modules of the system.

The article discusses the conceptual aspects of applying various approaches to talent management. It should be noted that most of the methods and technologies of talent management described in science are quite inflexible, since they do not take into account the influence of modern trends and are more focused on long-term strategic planning. The main focus of this paper is to attain a clear picture of global talent management as an integral part of personnel management in the conditions of Industry 4.0 enablers and barriers, and to establish the link between application of the concepts of exclusive and inclusive approaches in modern conditions. Conclusions are presented regarding their compatibility and feasibility of application in a modern organization. Based on the concepts of action analysis authors isolated the main destinations, which must determine the development of talents management theory. This has made possible the human-machine interconnection in Cyber-physical systems context utilizing the information generated from different smart devices. Under current conditions in this article these are the trends of the modern economy, including digital transformation and the exponential pace of development affecting the management mechanisms within the organization, which must also quickly adapt to new conditions. With regard to talent management, this means that the personnel management system should increase its flexibility in assessing and developing the potential of employees.

The power of the country and society is determined not only by the size of the country, the availability of natural resources, the power of financial capital, but also embodied in the human stock of knowledge and skills, intelligence and creativity. The driving force of social development is the human factor, which gives the economy an innovative and intensive character, structural dynamism, high quality.

In the modern world, man and his development is not only a factor that creates social wealth, but also a criterion for the progressiveness of socio-economic transformations in society.

Man and his abilities have traditionally played a leading role in social reproduction. However, the intensification of the processes of intellectualization and Informatization of economic relations has led to qualitative changes in the content of knowledge, skills and processes of their implementation.

At the end of XX-beginning of XXI centuries there is the need for further development of ideas about human resources, have undergone qualitative changes under the influence of the processes of intellectualization, the role of the state in regulating the sphere of education, aimed at creating prerequisites for the development of human capacities as a key factor of formation of competitive advantages of national economy in whole and its constituent territorial entities.

The study determined that in order to ensure the quality of human capital and its effective use, the state needs to develop measures that promote the development of competitiveness of human capital, promote employment of graduates of educational institutions and ensure joint work of Universities and enterprises while training specialists in accordance with the real requirements of the labor market in the country.
The concept of creating a digital clone of the Arctic territories

Published: October 2020

In the article, the concept of creating a digital clone to support the development of the Arctic territories, based on the representation of the territory in the form of target subspaces and modelling of the development of the territory in the form of a three-level model, is presented. The Arctic space is divided into target subspaces in accordance with the institutional-functional approach. In other words, the Arctic space is represented by a combination of systems, structures and their functions. The Arctic space comprises a holistic system, in which each element performs its relevant function. The function of the Arctic space consists in the ability to meet specific social needs. Human activities in the Arctic space are organised on the basis of institutions. In a general sense, the entire Arctic space can be said to consist of institutions and functions. The first level of the model represents the branch structure of the economy of the Arctic region. The second level consists of the target subspaces: “territories for the extraction of mineral resources”, “territories for recreational purposes”, “territories for fishing”. The third level shows the relationship between the target subspaces and the country’s economy.
