Separate collection of solid household waste by residents of multi-family homes

Introduction. The problem of solid household waste management, analyzed in the context of sustainable development, is relevant both in Russia and worldwide. On the one hand, it deals with vast legitimate and illegitimate landfills, polluting the environment. On the other hand, it deals with the depletion of natural resources and the potential usability of latent reserves of recyclable waste. It is inefficient to accumulate mixed waste and build recycling capacities, since they are accompanied by atmospheric pollutions. Separate collection of waste has a great potential. According to the estimates, Russia’s waste management system will move to a new level when local waste management companies come into operation. This new level will ensure environmental protection and higher standards of living. However, the intersectoral problem of separate waste collection cannot be solved by local waste management operators. This problem deals with urban development patterns and urban economies of the RF subjects, as well as the Russian industries, that use recyclable materials.
 Materials and methods. The co-authors have applied the system analysis of the research literature, statistical data and regulatory documents, as well as process modeling.
 Results. The co-authors have analyzed the engineering model of separate waste collection, implemented by residents of multi-family homes within the framework of the “nature – economic activities – nature” pattern. The accumulation of hazardous and oversized waste is organized as the separate subsystems of the waste management system implemented by the residents of a multi-family home.
 Conclusions. The co-authors propose to modify the system of household waste management to prevent the over-accumulation of substantial amounts of mixed household waste in waste containers near residential houses and in waste collection rooms. The introduction of ecologically friendly innovations is needed at each stage of the life cycle of any product.

In which case is working memory for movements affected by verbal interference? Evidence from the verbal description of movement

ABSTRACT Current perspectives on whether verbal interference affects working memory for movements have not yet reached a consensus. This study explored the causes of this controversy to reveal the relation between working memory for movements and the phonological loop. Experiment 1 explored whether the verbal description of movement moderated the effect of verbal interference (articulatory suppression) on working memory for movements. Verbal interference only affected working memory for easy-to-describe movements (lower accuracy). Experiment 2 excluded the interpretation of familiarity to the controversy and the effect of familiarity on the results of Experiment 1. Experiment 3 verified the results of Experiment 1 with another form of verbal interference, i.e., presenting irrelevant words visually. These three experiments suggest that the phonological loop is not recruited for processing working memory for movements in nature, but the two may interact through the verbal description prestored in the long-term memory. Thus, the current study provides a certain level of support for the separable movement-based subsystem hypothesis (Smyth, M. M., Pearson, N. A., & Pendleton, L. R. (1988).

Possibilities of using tourist and recreational potential in the conditions of decentralization (on the example of UTC of Volyn region)

The article deals with the comprehensive assessment of the tourist and recreational potential of Golovnenskaya UTC of Volyn region. Golovnenskaya UTC hasn’t known as a tourism destination among the Ukrainian tourists very well because of a lack of information about available resource potential, tourist attractions and tourist products of the community. Therefore, there is an urgent necessity to research these aspects. It could become an impulse in the activation the tourist flow, the lever of the formation of a competitive tourist product of regional and local significance. It also gives a great opportunity to increase the investment attractiveness of the territory, to solve partly the issue of employment of the population and essentially fill the budget of community. Based on results of the conducted research the following conclusions have been made: 1. The main natural recreational tourist resources and the components of the historical and cultural heritage, which determined the tourist specialization of the studied community have characterized. An important structure-forming element of the natural resource potential are the forest resources. They could be used for the development of the various forms of ecological tourism. In the community function 11 objects of the natural reserve fund. 2. Golovnenskaya UTC is situated in the historical and ethnographic region of Polissya and attracts the peculiarities of the traditional material and spiritual culture, language and so preserved the ancient relics of the Slavonic culture. 3. The analysis of the current state of tourism infrastructure in separate subsystems has conducted: placement establishments, food establishments, leisure establishments and consumer service, transport infrastructure. It is established that the tourist infrastructure is the weakest component of the tourist and recreational potential. The degree of its formation is quite low and does not provide a proper level of service to tourists. Each of the components of the tourist infrastructure of the community needs a separate, comprehensive, systematic approach to improvement and reform. For a comprehensive assessment of the problems and prospects of the tourism potential studied UTC of the Volyn region in the tourism sector elaborated SWOT-analysis. The main urgent problems in Golovnenskaya UTC are providing the infrastructure improvement and the information management of the main attractive objects of historical and cultural heritage and of the natural reserve fund, which are the most popular among the tourists, the low level of the development of the ecological tourism, the insufficient provision of the information about the tourist and recreational opportunities of the region.

Design of an intelligent vibration screening system for armyworm pupae based on image recognition

Biological control is a green and effective pest management method to mitigate or inhibit pests and pest effects by introducing natural enemies. The stinkbug is one of the insects used for biological control and fed on armyworm. It is necessary to separate the farm-raised armyworm from the sticky substrate after pupation. At present, the work is done manually, with high labor intensity, low efficiency and high cost. In this paper, an intelligent vibration screening system of armyworm pupae based on image recognition is developed. The system can effectively separate the pupae from the sticky substrate without damaging the pupae. The system is comprised of vibration subsystem, separation subsystem, image recognition subsystem and control subsystem. The pupa material is sticky and cannot be shaken off by vibration alone. Therefore, the separation subsystem uses the reciprocating motion of the brush to separate the armyworm from the substrate. Then, the image recognition technology is used to adjust the feed quantity in real time to ensure the optimal screening effect. Finally, the optimal working parameters, including separation speed, vibration frequency and feed quantity, are determined by using the design method of linear regression and linear programming. The experimental results show that the screening rate of the screening system can reach 90%, and the damage rate can be controlled within 5%.

DOCTRINAL ASPECTS OF OPTIMIZATION OF ADMINISTRATIVE PROCEEDINGS OF UKRAINE

The article is dedicated to the problems of optimization of administrative court system of Ukraine in connection with the ongoing reform of the courts. The available arguments for and against reforming the acting model of administrative justice of Ukraine are discussed. It has been clarified that the system of administrative courts in force has been specially approved for the adoption of Ukrainian society. The results of the statistical analysis show how it can successfully cope with deliveries to its arrogance. Indicate that you must reinsert the court system and recapture the administrative courts with the common courts. At the same time, with healthy administrative conviction, there are a few significant problems, among them we can call access to administrative justice and delimitation of administrative court jurisdiction from commercial and common courts jurisdictions. A closer look at the problems that need to be solved will require a farther and more thorough amendments to optimize the administrative courts activity. It has been concluded that the model of administrative justice in Ukraine since 2005 in the form of a separate subsystem of administrative courts of both the first and second links fully meets European standards and ensures the implementation of the rule of law, protection of rights and legitimate interests of individuals and legal entities, judicial control over legality and decisions of public authorities and their officials. There are no good grounds for its change (merger with courts of civil and criminal jurisdiction). Such reform will do more harm than good, negatively affect the quality of justice, the professional level of the judiciary. Prospects for further reform of administrative proceedings in Ukraine are in the area of introduction of modern mediation procedures, electronic proceedings, improvement of control over the legality of court decisions by higher courts (especially the Supreme Court of Ukraine), optimization of the burden on judges by establishing rational norms of their activity, depending on the number of cases received by the courts, the development and implementation of more effective mechanisms for the selection, training, retraining and accountability of judges.

Piece‐wise ellipsoidal set‐based model predictive control of linear parameter varying systems with application to a tower crane

AbstractIn this paper, a model predictive control algorithm for polytopic linear parameter varying (LPV) systems is proposed, which is based on an offline calculated sequence of robust one‐step controllable sets. At each sampling instant, a finite‐time optimal control problem is solved subject to a stabilizing constraint on the first state to ensure stability and recursive feasibility guarantees independent of the length of the prediction horizon and the cost function. An algorithm is proposed to compute a sequence of piece‐wise ellipsoidal one‐step controllable sets. The systematic application of the developed algorithm is possible via tensor product model transformation to a class of nonlinear systems. The size and shape of each set depend on the vertices of the polytopic LPV system and influences the control performance. By using the tensor product model transformation, different vertex representations can be obtained automatically. Furthermore, a trade‐off between model complexity and accuracy can be chosen, and the computational effort of the set calculation can be influenced. The developed method is applied to a tower crane system. The tower crane is modeled in a cascaded form with three separate subsystems. The couplings between the subsystems are treated as varying parameters. Each subsystem of the crane is transformed into a polytopic LPV system using the tensor product model transformation. By discarding the nonzero singular values, the complexity of the polytopic LPV model is reduced in terms of the number of vertices.

Data-driven design of fault detection and isolation method for distributed homogeneous systems

Driven by the increasing needs in large-scale industrial processes for maintaining stable operation using process data, a data-driven fault detection and isolation (FDI) method for distributed homogeneous systems is proposed in this paper. To this end, the original distributed homogeneous system is first decomposed into several separate subsystems using invertible transformations of the state, input, and output variables. On this basis, the fault detection method according to the one-step identification of the stable kernel representation (SKR) is developed for the transformed subsystems. It is followed by the fault estimation for the transformed subsystems along with implementation on fault isolation for the original distributed system. Experiments comparing the proposed FDI method and the centralized FD method are performed using a numerical example. In this specific example, the proposed FDI method has a computational complexity of 2.32×107, while the centralized FD method has a computational complexity of 9.31×107. This shows the effectiveness and advantages of the proposed method.

Physical simulation and compatibility evaluation of multi-seam CBM co-production: Implications for the development of stacked CBM systems

Multi-layer co-production is a mainstream method for efficient development of coalbed methane (CBM) and coal series gas under multi-seam conditions. However, interlayer interferences during CBM co-production caused by differences in reservoir properties (especially permeability and pressure) between stacked CBM systems severely restrict the output of CBM from the production layers. The identification of interlayer interferences and optimization of production layer combinations are important scientific issues that need to be explored to achieve high CBM production. Physical simulation is an effective means of accomplishing this research objective. Physical simulations of CBM co-production were performed under designed permeability and pressure combinations based on self-developed experimental equipment, which is mainly composed of an injection subsystem, a vacuum subsystem, the model body subsystem, and a separation and metering subsystem. Coal samples were collected from three CBM basins in China to form a series of five permeability levels, specifically 0.2, 2, 10, 50, and 100 mD. We focused our analysis on the contribution of gas production from each production layer using the gas flow data obtained from the physical simulation experiments. The co-mining compatibility of the production layers is divided into four types based on the grading evaluation of gas contribution: Grade I, II, and III compatible, and incompatible, which represent gas production contribution of the weak seam ≥37.5%, 25%–37.5%, 12.5%–25%, and ≤12.5%, respectively. On this basis, a template for discriminating CBM co-production compatibility is constructed using the permeability ratio and pressure difference as basic parameters. The gas and water production data of representative CBM wells in the Bide-Santang basin were used to verify the reliability of the template, and the compatibility discrimination results show consistency with the production data. The average daily gas production per unit of coal thickness presents a decreasing trend with deteriorating compatibility of co-producing seams. Finally, an integrated technical process for the development of stacked CBM systems is proposed, including the hierarchical optimization of production layer combinations, identification of interlayer interferences and sources of produced water, and selection of suitable development methods and technology. We divided the production layer combinations into four types representing different development potentials based on the hierarchical method: most favorable, favorable, sub-favorable, and unfavorable. Suggestions are made for the key geological constraints (weak water-bearing reservoir, compatibility of CBM systems, shallow groundwater interference, and deep CBM condition) and specific development strategies for different types of production layer combinations. This study will enrich the geological understanding of CBM co-production and provide theoretical and technical support for the efficient development of stacked CBM systems.

Interlaboratory validation of a hanging pendulum thrust balance for electric propulsion testing.

A hanging pendulum thrust balance has been developed by Imperial College London in collaboration with the European Space Agency (ESA) to characterize a wide range of static fire electric propulsion and chemical micro-propulsion devices with thrust in the range of 1 mN to 1 N. The thrusters under investigation are mounted on a pendulum platform, which is suspended from the support structure using stainless steel flexures. The displacement of the platform is measured using an optical laser triangulation sensor. Thermal stability is ensured by a closed loop self-compensating heating system. The traceability and stability of the calibration are ensured using two separate calibration subsystems: a voice coil actuator and a servomotor pulley system. Two nearly identical thrust balances have been constructed, with one being tested in the Imperial Plasma Propulsion Laboratory and the other in the ESA Propulsion Laboratory. Both balances show a high degree of linearity in the range of 0.5 mN-100 mN. Both instruments have demonstrated a stable calibration over several days, with an estimated standard deviation on thrust measurements better than 0.27 mN for low thrust measurements. The same electric propulsion test article was used during both tests: a Quad Confinement Thruster (QCT) variant called QCT Phoenix. This thruster differed from previous QCT designs by having a newly optimized magnetic topology. The device produced thrust up to 2.21 ± 0.22 mN with a maximum specific impulse of 274 ± 41 s for an anode power range of 50 W-115 W.

Vague eggs and tags: Prevelar merger in Seattle

AbstractThis study describes prevelar merger, the raising of low-front /æ, ɛ/ and lowering of mid-front /e/ before the voiced velar /ɡ/, in Seattle, Washington. In the most advanced part of this change in progress, all twenty speakers (age 18–62, half men, half women, all white) produced /ɛɡ/ and /eɡ/ (beg, vague) as upgliding diphthongs merged in F1 and F2 directly between their nonprevelar counterparts (dress, face). /æɡ/ (bag) was also diphthongal, but its height varied between speakers, with middle-aged men showing near-complete three-way merger with beg-vague and younger speakers raising less, suggesting reversal or avoidance of this component. Previous work lacked information about vague and thus described bag- and beg-raising as failing to reach the height of nonprevelar face. This study revealed that vague is lowered, creating a merger target for both raised beg and bag within a separate diphthongal prevelar subsystem.

Thermal-hydraulic simulation of IFMIF-DONES Test Cell atmosphere

The test cell (TC) serves as irradiation chamber in the IFMIF-DONES facility, which aims to irradiate material samples with a highly energetic deuterium-lithium based neutron source to contribute to the development of candidate materials to be used in the first wall components of future fusion reactors. The TC provides space for several sub-systems and their components and it is filled with helium on sub-atmospheric pressure during normal operation. The internal components as well as the wall of the TC are exposed to volumetric heat load coming from the radiation and some of them have active heating/cooling. The internal flow of the atmosphere induced by natural convection and the various thermal state of the components consists of a complex, thermally strongly coupled system. An integrated Computational Fluid Dynamics (CFD) simulation has been developed in OpenFOAM solver, in order to provide a consistent approach for the design of the heating/cooling sub-systems of the TC components, as well as to estimate the heat load on the passively cooled structures. Additionally, such an integrated solution gives better understanding and consistency check of the separate sub-systems simulations. The purpose of this paper is to describe the current status of this simulation model, as well as analyzing the thermal condition of the TC during normal operation, considering that the different part and sub-systems have different level of design maturity.

Введение в новое мироведение (эковедение)

The world is an integral (holistic) “system of systems” (SoS), a set of self-sufficient, but interconnected (energy-materially, information-genetically and mental-conceptually), structural-functional formations (SFF), which are in a permanent state of stable development. Separate subsystems of the world system are the space and terrestrial oecumene, geotories (closed socio-natural systems) and civilizations, biosphere and technosphere, the world of reason (noosphere) and the cognitive world of a man. Metasystem as a whole (SoS) — is fractal (with SFF similar in space and time) dynamic system, in which "what's above, the same is below", "what happened is what will happen." Global studies is a complex of scientific knowledge, established generally accepted information and individual speculative assumptions, views and intuitive sensations about the world system as a whole and its individual parts, laws of their dynamic functioning and development, as well as a targeted vision system (foresight) of the present, the past and the future of SoS on the whole. Fractality of the world system allows us to use, for its general management, conseptions inherent in one of its constituent parts ("want to know the Universe — cognize a human himself", and vice versa). Cosmology, natural history, social science and human studies are determined by the same structural and functional concepts, in particular, the cyclical nature of both separate SFF and SoS as a whole. Therefore, the present article examines basic principles of a new metasystem-based world studies on the example of eco-studies (ecological, economic and energy conceptions on development of the planetary house-ecos in which we live: from the Greek oikos - house, place of residence, oikumen). At the same time, based on ideas about cyclical nature of the development of terrestrial oecumene and Eurasian civilization, an attempt is made to present the structure of a new project "Targeted vision of the new world" for the second half of the 21st century and for the coming 36-year period, "Christmas Eve" is the culmination of the 144-year "imperial" cycle.

Automation of individual operations of the transport process to create sufficient conditions for the efficient functioning of digital transport and logistics

The current evolution in information technology will enable the railway industry to bring the concept of a customer-centric marketing approach to life. At present, the main factor for ensuring the competitiveness of the transport company, which emphasizes the position in the transport services market, is to provide a service with a qualitatively new modern level of services, based on the opinion of consumers of these services. The digitalization of railway transport and logistics, the use of modern technical means and programs allows one to improve the efficiency of the transport complex in general and on separate subsystems, as well as to ensure high quality of services. The introduction of an automated procedure for the optimal placement and fastening of the cargo in the production process will allow transport and logistics market operators to predict the occurrence of risk cases at each stage of the transport process. Algorithms for selecting the type of rolling stock to transport the cargo of the relevant category and the typical scheme of placing cargo in it, as well as the method of fixing cargo, have been developed and presented. Since the digitization of supply chains depends more on the type of cargo and the type of rolling stock chosen for transport, the construction of algorithms is based on the example of a flat-base cargo. The development of the automated procedure is based on the construction of a model scheme for placing and fastening a particular type of cargo. The results of using the developed automated procedure make it possible to determine the magnitude of the load shift and tension in the fasteners under the influence of various factors.

РАЗРАБОТКА СТРУКТУРНЫХ СХЕМ И АЛГОРИТМОВ РАБОТЫ СИСТЕМЫ АВТОМАТИЧЕСКОГО УПРАВЛЕНИЯ МНОГОФУНКЦИОНАЛЬНЫМ ЭНЕРГЕТИЧЕСКИМ КОМПЛЕКСОМ

Among the promising automatic control systems, logical-dynamic control systems that change both the structure and parameters of the control device using switches formed on the basis of a certain logical algorithm have proven themselves well. The use of logical algorithms as part of MACS subsystems for complex technical objects makes it possible to increase the static and dynamic accuracy of control due to purposeful qualitative and quantitative changes in the control signal. This approach will give the control system fundamentally new properties that allow to fully take into account the nature and dynamics of the movement of the control object. When developing existing logical control algorithms, the issues of their application for multi-connected and multifunctional objects control were not considered. Common to existing logical algorithms is that when switching the structure and/or changing parameters, only the dynamics of its own subsystem is taken into account, which is unacceptable in the case of multi-connected dynamic object control, since cross-links have a significant impact on the quality of control. Thus, the problem of synthesis of logical algorithms for multi-connected objects control is an actual theoretical and applied problem. Despite the considerable amount of research conducted in this area, the application of logical algorithms for complex multidimensional objects control is not sufficiently considered, and there is no unified design concept for this type of MACS, taking into account the required quality of functioning in various operating modes. In this regard, there is a need to synthesize algorithms for logical multi-connected control that form control signals in order to coordinate the actions of all separate MACS subsystems in accordance with new external conditions and operating modes. The problem under consideration determined the purpose of this work and the research objectives.

АЛЬТЕРНАТИВНО-ПЕНИТЕНЦИАРНОЕ ПРАВО КАК ФОРМИРУЮЩАЯСЯ ПОДОТРАСЛЬ УГОЛОВНО-ИСПОЛНИТЕЛЬНОГО ПРАВА

In the article, the author discusses the possibility of distinguishing within the framework of penal law a relatively separate regulatory subsystem, which is a set of legal norms regulating the execution of criminal penalties against convicted persons that are not related to isolation from society, and separating them into a new self-sufficient sub-branch of penal law. The study aims to understand the processes of differentiation and integration present in penal law, and to assess the prospects for the allocation of a new sub-branch in the matter of penal law - alternative penal law. The objectives of the study are to define the concept of alternative penal law and its place in the system of penal law; to analyze the system-forming factors in penal law; to identify the criteria for distinguishing general, subject-based and functional institutions within the framework of alternative penal law; to formulate proposals for improving the separate normative subsystem “alternative penal law” that affect the structure and content of the Penal Code of the Russian Federation. In the course of the research, general and specific methods of scientific cognition were used: dialectical, formal-logical, functional, system-structural, comparative-legal, as well as the method of legal modeling. The author presents arguments in favor of the separation of the norms of penal law that regulate the part of the subject of penal law. As a structure-forming factor that unites institutions in alternative penal law, the author notes the form of criminal liability implementation - criminal penalties that are not related to isolation from society. The author analyzes the institutions of the future general and special parts of alternative penal law, which emphasize the existing institutional insufficiency of penal law norms regulating the legal status of convicts serving criminal sentences that are not related to isolation from society. To assess the current state of the regulatory subsystem of alternative penal law and its ability to grow to a higher level, the following criteria are used: its own object and method of legal regulation; special subject-based composition of alternative penal relations; the presence of an autonomous leading goal; its own principles; complex intra-structural differentiation represented by homogeneous and single-order institutions of penal law; legislative isolation of the alternative penal sphere. The author formulates the conclusion that today only the rudiments of alternative penal law have been formed as an integral part of the system of the branch of penal law, a part that only claims the status of an emerging sub-branch.

Influence of climatic factors on the implementation of intelligent transport system technologies in the regions of the Far North and the Arctic

Taking into account natural and climatic factors in various regions of the Far North and the Arctic is extremely important for organizing the successful pickup and delivery of various goods and passengers. These factors have a particular impact on the transportation of goods and passengers by road. The well-known advantages of motor vehicles over other modes of transport, such as mobility, the possibility of door-to-door delivery, low capital costs for transportation organization, etc., make this mode of transport indispensable in the Far North and the Arctic. Meanwhile, the requirements for the reliability and safety of transportation are increasing significantly.The paper discusses a method of forecasting the operation time of temporary transport routes (winter roads) used for transportation most of the year. The volume of transported goods and transportation safety largely depend on the accuracy of such forecasting. Changes in weather conditions, deterioration of visibility, a sharp drop in temperature also have a significant impact on transportation safety and reliability, which makes it urgent to inform the participants of the transportation process about the current situation on the transport route. At the present stage, the main direction of road transport development is the expansion of the use of intelligent transport systems. The development of satellite navigation, on the one hand, and equipment of vehicles with on-board systems to inform drivers about weather conditions along the route, on the other hand, have created the basis for the use of intelligent transport systems (Prikhodko 2011), in particular, meteorological monitoring and information subsystems. The data received from the meteorological monitoring subsystem using external means of information should be sent to the driver for making a prompt decision on how to operate the vehicle. In this regard, it is required to design highly automated vehicles (HAVs), when data are processed from all vehicle subsystems in aggregate, and not from each separate subsystem. HAVs, or so-called unmanned transport systems, are a necessary link in the development of northern territories and in solving one of the global problems of the Strategy of Scientific and Technological Development of the Russian Federation — “territorial connectivity”.

On a Systematic Approach to the Study of International Migration Processes

The article is devoted to the review of current trends in international migration in conditions of turbulence. The article substantiates the need to study migration processes within the framework of a single global migration system consisting of separate migration subsystems formed on a geographical basis and having stable internal and external migration links. The concept of “unified world migration system EMMS is given. The nature of the impact of all system-wide factors on international migration is considered. Along with the impact of socio-economic factors, in particular, the reaction of migrants to crisis phenomena in the economy, which is reflected in the scientific literature, attention is paid to the nature of the impact on the mobility of the population of factors related to the deterioration of the human environment, climate change, disasters, and the coronavirus pandemic. As a hypothesis, the article substantiates the assumption that the system-wide factors influence the scale and speed of migration exchange between individual migration subsystems in different directions, which served as the basis for providing for an increase in migration activity of the population in the future. Analytical and statistical methods, as well as the method of geographical zoning, were used to solve the research problems. The forecast of the number of international migrants by migration subsystems up to 2050 is made, and structural shifts in the distribution of international migrant flows by migration subsystems are revealed. In the international migration exchange in 2050, the number and share of migrants from the migration subsystems of Africa, Asia and Latin America will increase. The results obtained can be used for further in-depth research of migration patterns within the framework of a single global migration system, development of a methodology for predicting movements, taking into account various hypotheses of changes in migration behavior of the population.

Affective forecasting: A selective relationship with working memory for emotion.

Affective forecasting (AF), the ability to predict one's future feelings, is important for decision making. We posit that AF entails the ability to maintain and evaluate an emotional feeling state, and thus requires affective working memory (AWM; Mikels & Reuter-Lorenz, 2019). To test this hypothesis, a series of studies investigated whether individual differences in AWM are related to AF ability. In the first study, we document that measures of AWM and AF are positively related, whereas an analogous measure of visual working memory is unrelated to AF in separate groups of participants. Two further within-group studies (1 preregistered) demonstrate that maintenance of affective information predicts AF performance, whereas maintenance of brightness information does not. Further, 2 additional measures of visual working memory (Corsi block-tapping and change detection) did not independently predict AF ability. Taken together the results demonstrate a reliable and selective relationship between AWM and AF, suggesting that AWM is a separable working memory subsystem and an elemental capacity that contributes to the type of higher-order emotional processes involved in AF.

The article examines the features of digitalization impact on the functioning of agricultural enterprises. The evolution of technological patterns in agriculture is analyzed and the role of digitalization in the formation and development of modern technological production of agricultural products is revealed. Technological factors of updating the production base of agricultural enterprises are determined. The influence of digitalization on each separate subsystem of agricultural enterprises is considered with the determination of the overall synergetic effect.

СТАТИСТИЧНИЙ АНАЛІЗ СУЧАСНИХ ТЕНДЕНЦІЙ РОЗВИТКУ ТУРИЗМУ ВИШЕГРАДСЬКОЇ ЧЕТВІРКИ

The paper presents the research results of tourism state and patterns development in the Visegrad Group. The regional grouping of Central and Eastern Europe, the Visegrad Group, has become a separate subsystem of the European Union, which has received economic, logistical, cultural and political content. These processes are important for Ukraine. The experience of the Visegrad Group, the ability to quickly solve current issues and face the challenges, understanding the real hierarchy of priorities while preserving the national identity of the Visegrad Group (VG) are significant for Ukraine. Tourism is an area that can positively influence both the development of the integrated structure as a whole and the socio-economic development of its member countries. The article carries out a comparative analysis of tourism development trends in the Visegrad Group countries, Europe and the world, as well as develops recommendations for assessing the cooperation prospects between Ukraine and the VG using econometric methods. To achieve the goal of the study, a comparative analysis of global, European and Visegrad trends in tourism was developed, arrivals of international tourists on the amount of income from international tourism by conducting a correlation-regression analysis, substantiated and developed applied aspects for forecasting the potential mutual benefit from cooperation between Ukraine and the VG. According to the World Trade Organization, the forecast of the number of international tourists in the world for 2020-2021 was made. Based on the impact assessment of the number of international tourist arrivals on the amount of income from international tourism, a linear regression model was built, the adequacy and reliability of the regression coefficient was confirmed by Fisher's and Student's estimates. During the analysis (from a priori analysis, proving the quantitative and qualitative homogeneity of the two sets, to the construction, evaluation and analysis of the obtained model) a regression model was built, which can be recommended to be used in the impact analysis of tourist arrivals on international tourism. A comparative analysis of the dynamics of international tourist arrivals and revenues from international tourism in Poland and Ukraine was done. As a result of Poland's experience research, a model of revenues from international tourism is recommended, the factors of which are gross investment (% of GDP) and the number of tourist arrivals.
