Information-psychological influences, attacks, and operations do not have a physical manifestation but generate destabilizing internal and external processes within a state. These processes cause aggression, anxiety, and dissatisfaction among the population, potentially leading to open physical conflict. The use of the Internet enables extremist organizations to access mass media, spreading propaganda, informing about their goals, tasks, measures, and forms of support. The authors emphasize the significant impact of modern information and communication technologies on increasing threats to political stability and the security of any state. The aim of this paper is to highlight foreign experiences regarding organizational and legal measures that prevent the spread of disinformation, aimed at inciting hostility and hatred within a state. The study draws on experiences from large-scale protest actions, organized and coordinated through social networks on the Internet. The authors note that blogs, social networks, electronic maps, and video hosting sites are currently used without restrictions for political destabilization. Social networks enable immediate support from like-minded individuals and the publication of extremist materials, which contribute to the escalation of socio-political, ethnic, and interfaith conflicts. The main research methods are comparative analysis, statistical method, historical method, structural-functional method of cognition. Having studied the periods of formation of the system for countering the spread of disinformation in the EU, the authors concluded that the work on countering the spread of disinformation is conducted comprehensively and systematically and is constantly being improved in accordance with the challenges. In the EU countries, not only the practice of combating disinformation has been developed, but also an array of normative legal acts has been adopted to prevent the spread of disinformation. The European experience demonstrates the importance of a balance between freedom of speech and security measures in the information space. Such a comprehensive and conceptual approach should be the basis for creating a system for countering the spread of disinformation in Ukraine. [ABSTRACT FROM AUTHOR]

The paper analyzes the use of intangible assets to shift profits to jurisdictions that apply low income tax rates. The possibility of using standard methods of transfer pricing for valuation of intangible assets was studied. It has been established that it is very difficult to evaluate intangible assets based on the principle of an arm's length, and in many cases it is impossible. It has been proven that the best estimate of intangible assets is the fair market value, which is determined by the increase in profit, provided by the use of the corresponding intangible asset. The introduction of taxation based on the source principle is the best alternative to transfer pricing methods, and does not require the valuation of intangible assets. The tax service must control the total income of the payer and its proper taxation according to the source principle. The payment of royalties must be made from the profit after its taxation in the country of the source of income, which excludes taxation in the country where the intangible asset is registered. The place of taxation of the paid royalty amount is determined by the resident status of the recipient. Payments to residents are taxed in the country of source, and the remainder is subject to repatriation to the non-resident. The meaning of the "resident" concept in relation to physical and legal entities has been clarified and criteria for their unambiguous identification have been introduced. The only criterion for determining the resident status of a natural person is his/her citizenship. Effective tax incentives are proposed for disclosure of non-resident asset owners, which allows taxation of the worldwide income of state residents. The introduction of taxation based on the principle of source automatically excludes the possibility of double taxation and provides for the cancellation of all tax agreements that do not meet the proposed criteria for the identification of physical and legal entity-residents. It is extremely important for Ukraine to cancel agreements with Cyprus, the Netherlands, Luxembourg and the British Virgin Islands. [ABSTRACT FROM AUTHOR]

The article is dedicated to the analysis of the place and application of the new Law "On Administrative Procedure" in regulating public electronic services in Ukraine. Enacted on December 15, 2023, the Law aims to establish a system of unified, understandable, and transparent interaction between public authorities and citizens and businesses. The article examines the main provisions of the Law, focusing on the principles of administrative procedure and norms regulating the resolution of administrative matters using electronic digital technologies. Based on the analysis of legislation texts, comparative analysis, and consideration of practical aspects of the new law's implementation, the conclusion is drawn regarding the importance of applying its norms to the sphere of public services, including those provided through digital technologies. It is found that the Law of Ukraine "On Administrative Procedure" sets general standards for administrative procedure ensuring the observance of rights of individuals and legal entities in relations with administrative authorities, regardless of whether such interaction occurs through physical or electronic channels. Special legislation may define the specifics of providing certain types of public services, but the general standards of the Law of Ukraine "On Administrative Procedure" must be adhered to. The article also highlights the main directions for further research and possible directions for further development of legislation in this area. The application of the provisions of the Law of Ukraine "On Administrative Procedure" allows not just to copy the logic of the paper world into digital services, but to develop innovative approaches. This means that the right to participate in the administrative process can be implemented through online offices, the possibility to submit documents in electronic format, support for communication through digital channels and the creation of additional functions that complement the main service.

The article is devoted to certain legal aspects of the impact of the FinTech-industry on public finance. The emergence of new various financial services and instruments requires their appropriate legal assessment and effective legal regulation. Despite numerous publications and scientific studies of various aspects of the manifestation and application of FinTech, The Theory of legal regulation of digital finance is at the initial stage of its formation and is fragmented. The paper reviews special literature, devoted to the problems of legal regulation of virtual assets and related payment services. It emphasizes the need to observe a balanced conservative nature of legal regulation of financial relations in the context of the introduction of digital financial technologies, taking into account the tasks of protecting both public interests and ones of individuals. Based on the analysis of the current legislation, trends towards breaking the state issue monopoly due to the introduction of electronic money in the economy are revealed. The conclusions and theoretical generalizations are presented, the main of which are: 1) cryptocurrencies as alternative units of account pose a threat to the dominance of public currencies, as they make competition between private financial agents and states and their associations possible; 2) the issue of legal assessment of cryptocurrencies has not yet been finally resolved, including their legal nature remains debatable; 3) in its essence, electronic money is a kind of "electronic bill", but does not meet the formal characteristics of such a security; 4) there is a tendency to weaken the imperativeness of legal regulation of the sphere of monetary circulation fundamental for public finances by ensuring local rule-making within individual payment systems [ABSTRACT FROM AUTHOR]

The article highlights the legal concerns surrounding the protection of minors' personal data. The writers have conducted an original study of the sources regulating civil and labor relations in the field of acquiring and using personal data. The expansion and use of information technology and online communications can potentially lead to the violation of personal rights by the owners of personal data, both in workplace settings and in the daily lives of ordinary residents. The purpose of this article is to highlight issues concerning the collection, storage, use, and dissemination of the personal data of a minor, as well as to develop methods to protect the personal data of a child based on a comprehensive analysis of international acts, Ukrainian legislation, unique literature, and case law materials pertaining to the protection of personal data of a minor. Based on the analysis of national legislation and case law of the European Union, the author concludes that the right to personal data protection is one of the forms of realization of the right to respect for private and family life. The obligation to protect person's rights to processing and storage of his or her private information is a negative obligation on the part of both the State and the owners of personal data. The article addresses current difficulties concerning the security of children' personal data under current civil and medical legislation in Ukraine and other countries. The provisions of the General Data Protection Regulation, the California Consumer Privacy Act, and Ukraine's "On Personal Data Protection" Law are compared. Possible steps to establish further protection of children's personal data during collection and processing, whether utilizing websites, video games, online purchases, and so on, are proposed. The paper concludes that state functions should be executed without necessitating individuals' consent for the collection of personal data. Personal data processing should be carried out within the framework and on the basis of Ukrainian laws and regulations, taking into account international conventions in this area. The analysis of methods for safeguarding children's personal data enabled the identification of supplementary avenues for data protection. These include acquiring copies of personal data by both children and their parents, rectifying inaccuracies, completing incomplete data, exercising the 'right to be forgotten' and the 'right to erasure' of personal data, invalidating transactions, and seeking compensation for material and moral damages arising from the unlawful use of personal data [ABSTRACT FROM AUTHOR]

The study aims to determine the legal nature of freedom of will, its definition and its place in the legal system as an idea, principle and norm. Research methods were chosen to consider the set goal and tasks: general and unique scientific methods of scientific knowledge of legal phenomena. In particular, the following research methods were applied: comparative-legal, formal-logical, systemic-structural, dialectical and others. These methods were used in their interdependence. The methodology contains information on philosophical aspects, methodological foundations of scientific knowledge, study of the structure and main stages of research. The paper examines the combination of two definitions, freedom and will, taking into account the legal specificity. The study proves that freedom in law is the possibility of behaviour not prohibited by law and the absence of coercion, except in cases, provided for by law. Will, in law, is the ability to control one's actions and manifestation from the outside, conscious regulation of one's behaviour, which is not limited to the legally defined possibility of behaviour. It is noted, that freedom has a passive character as the possibility of specific behaviour, and will is the active use of one's rights and opportunities. Will is the active use of freedom. The author emphasizes that although free will has a transcendent basis, it is inherent in law, confirmed by its global manifestation in legal science and practice. It is emphasized, that free will is a multi-layered, complex legal concept with a fundamental meaning. The position on the possibility of understanding freedom of will as a legal idea, an idea-principle, an idea-institute and an idea-norm that are not directly enshrined in normative legal acts, but reflected through the content of other legal institutions, principles and norms based on it, is substantiated. It is proved, that in the broadest sense, freedom of will in law is a legal idea, and the author's definition is proposed [ABSTRACT FROM AUTHOR]

The results reported here represent the first stage in the development of a full-featured laboratory system aimed at studying machine learning algorithms. The relevance of the current work is predetermined by the lack of network small-size mobile robots and appropriate control software that would make it possible to conduct field experiments in real time. This paper reports the selection of network data transmission technology for managing mobile robots in real time. Based on the chosen data transmission protocol, a complete stack of technologies of the network model of a multi-agent system of mobile robots has been proposed. This has made it possible to build a network model of the system that visualizes and investigates machine learning algorithms. In accordance with the requirements set by the OSI network model for constructing such systems, the model includes the following levels: 1) the lower level of data collection and controlling elements – mobile robots; 2) the top level of the model includes a user interface server and a business logic support server. Based on the built diagram of the protocol stack and the network model, the software and hardware implementation of the obtained results has been carried out. This paper employed the JavaScript library React with a SPA technology (Single Page Application), a Virtual DOM technology (Document Object Model), stored in the device’s RAM and synchronized with the actual DOM. That has made it possible to simplify the process of control over the clients and reduce network traffic. The model provides the opportunity to: 1) manage the prototypes of robot clients in real time; 2) reduce the use of network traffic, compared to other data transmission technologies; 3) reduce the load on the CPU processors of robots and servers; 4) virtually simulate an experiment; 5) investigate the implementation of machine learning algorithms.

The results of the study of the developed scheme of the selector of significantly different pressures, based on combining flow and pressure dividing valves with flow summarizing valve, allowing a proportional increase of all interthrottle pressures of the scheme are presented in the paper. The mathematical models that provide a choice of optimal parameters of the scheme elements and the study of the effect of the influence factors on the operation quality of the throttle selector scheme are obtained. These models are a system of n nonlinear algebraic equations that can be solved by known numerical methods. Using pressure reproduction tools, based on the developed scheme is especially relevant for gas-dynamic synthesizers of mixtures with a given composition with microconcentrations of components. Due to providing a linear change of interthrottle pressures in the scheme and applying gas-dynamic synthesizer of linear metering capillaries in the mixer, there is the prospect of obtaining complex multicomponent mixtures with microconcentrations of components with higher concentration maintaining accuracy than in the known tools for the continuous preparation of mixtures with given composition.

Analysis of the approaches to solving the problem of operational control of the hydraulic system parameters was performed in the paper. The paper describes a method of providing uniform motion of the output link of the hydraulic motor by setting the adjustable throttle on the discharge manifold of the hydraulic system. Throttle generates pressure pulsations in the discharge chamber, which compensate sharp pressure increase in the pressure chamber of the hydraulic motor. Throttle parameters, providing a constant speed of the output link are calculated. Based on the calculation results, the design of an adjustable throttle with a rotating spool is developed. The description and operation principle of the designed adjustable throttle, the scheme of its inclusion in the hydraulic network are given. The developed test bench of the throttle and its operation principle are described. The paper presents the results of functional tests of the designed adjustable throttle. The results of theoretical and empirical research, based on which it was concluded on a fundamental confirmation of the proposed method of pulsation dampening in the hydraulic system are compared.

The paper analyzed the distribution of capacitive currents in the winding of measuring high-voltage autotransformer at its operating frequency 50 (60) Hz. It is revealed that idling high-voltage autotransformer at significant nominal dividing coefficient these currents can acquire essential values against the current idling, which can affect the accuracy of large-scale conversion of high-voltage measuring autotransformers. The paper presents an approach to account values of interlayer capacitive currents in the windings of high-voltage autotransformers to clarify the distribution of voltage on their low-voltage (output) winding parts. It is shown that the distribution of capacitive currents significantly different to the first, last and middle layers of windings that must be considered when designing the windings of high-voltage autotransformers and calculate the number of turns in the respective high-voltage and low-voltage parts of windings. This analysis is particularly important for the development of standard measurement tools using high-voltage autotransformer scale transformation. [ABSTRACT FROM AUTHOR]

This paper reports a study into the influence of sodium carbonate concentration (10, 30, and 50 kg/m3) in the simultaneous presence of sodium thiosulfate (250 kg/m³) and quinhydrone (5 kg/m³) on the coefficient of the phase distribution of hydrogen sulfide in a quinhydrone absorbing solution. The research was carried out at the laboratory installation using chemical analysis methods of liquid and gas phases. It has been found that the coefficient of phase distribution increases dramatically with an increase in the degree of saturation of the quinhydrone solution with hydrogen sulfide. At the same time, in the presence of sodium thiosulfate in quinhydrone absorbing solutions, the coefficient of phase distribution increases compared to carbonate solutions of the same concentration. Thus, the partial hydrogen sulfide pressure over a quinhydrone solution at low degrees of hydrogen sulfide saturation (up to 3 %) is 5...10 times larger than that over soda solution, while at high degrees (60...80 %) it is almost the same. It can be argued that at the high concentrations of sodium carbonate and the degree of the saturation of quinhydrone solution with hydrogen sulfide the effect of sodium thiosulfate on the partial pressure of hydrogen sulfide decreases. An equation of the effect exerted by the NaНS concentration and the starting Na2CO3 concentration on the H2S partial pressure over quinhydrone solutions has been proposed. Based on the experimental studies’ results, the equilibrium constant values for a hydrogen sulfide chemisorption reaction involving a quinhydrone solution have been calculated. To ensure the high absorption capacity, the process of hydrogen sulfide chemisorption should be carried out using solutions with a maximum concentration of sodium carbonate, 40...50 kg/m3. The presence of ballast components (Na2S2O3, NaHCO3) slightly reduces the sorption capacity of an absorbing solution. The results obtained could be used in engineering calculations and when developing technology for purification of fuel gases from hydrogen sulfide by a quinhydrone method. [ABSTRACT FROM AUTHOR]

The paper deals with experimental methods for studying the biological properties of water. The existing problems of theoretical and experimental study of the anomalous water properties that are not consistent with the known theoretical models were considered. The crucial importance of water structure features for normal functioning of living organisms was shown. Since the standard classical methods of physical-chemical analysis do not provide the possibility of implementing experimental evaluation of specific biological properties of water, a method for registering images of the gas discharge flow of liquid-phase objects in an electromagnetic field with the subsequent software image processing based on cluster analysis was proposed as an alternative. The following tasks were set and solved in the paper: allocation of patterns in gas discharge water glow images, digital processing of image samples, construction of image classification methods and algorithms. Bezdek-Dunn algorithm (Fuzzy ISODATA algorithm, FCM algorithm) was used for the fuzzy image clustering. The effectiveness of the proposed research method was tested on real data samples for waste and natural water samples. The characteristic features of the gas discharge glow of natural water as the coherent material, which provides a significant response to an external impact in the form of an electromagnetic field were determined. The obtained results of the extraction of specific parameters from the structural features of the gas discharge glow images show the effectiveness of algorithms for fuzzy clustering of water samples with different biological properties.

The study of the temperature field of power semiconductor devices, operating in semiconductor apparatuses, either non-contact or hybrid was carried out in the paper. It was also shown that the main mode of the current load of power semiconductor devices, operating in semiconductor apparatuses is a pulse mode. Analytical method for calculating the values of the temperature rise in the structure of power semiconductor devices when subjected to a current pulse of arbitrary shape based on a model that adequately reflects the design of semiconductor devices was used during the studies. To calculate the thermal mode of power semiconductor devices, a technique, based on using the simplified thermal models, where the solder layers are taken into account due to expansion of thermal-resistance equivalent tungsten layers is also used. However, unlike it, the method, proposed in the paper provides a higher accuracy in calculating the temperature rise in the structure of power semiconductor devices since all layers of these devices are taken into account. Also, calculation by this method takes into account the dependence of physical properties of materials of the thyristor components on the change in their temperature. Solving the system of heat conduction equations, set up for the model that adequately reflects the thyristor design, was performed by finite difference method using the implicit scheme. When calculating the transient thermal resistance using the real model for different types of thyristors, difference in its value reaches 5-16 % compared with the calculation using the simplified models. Thus, calculation of the temperature rise in the structure of power semiconductor devices is appropriate to carry out using the proposed method based on a model that adequately reflects the design of these devices. The described calculation method can be used for the rational choice of a power semiconductor device as a basic element of hybrid and non-contact semiconductor apparatuses in systems of their computer-aided design. The paper presents examples of calculating the thermal mode of semiconductor devices for the most common types of semiconductor apparatuses. [ABSTRACT FROM AUTHOR]

In modern technology, there are more and more cases of action of impact loads on work items of buildings, machines and constructions, therefore, the strength calculations of these items under the dynamic effects become important. To solve the problems, arising from the dynamic effects, it is necessary to use the continuum mechanics methods and, in particular in many cases, the methods of the dynamic theory of elasticity. Analytical studies allow to find the exact problem solutions, which is very important, because the exact solutions allow to estimate the main features of the solution in general - the nature and the extent of influence of various set parameters on it. On the other hand, exact solutions are always reference and needed, in particular, for developing numerical methods for more complex cases. This work is a continuation of the works of N. Rassoulova, G. Shamilova, dedicated to studying the propagation of unsteady waves in the prisms of rectangular cross section. Approach to solving this problem differs markedly from all previous issues of the dynamics of rectangular prisms, which mainly investigated their dispersion characteristics. This paper deals with studying the process of propagation of unsteady waves in semi-infinite rectangular bars, exposed to impact shear forces on the face platform. System of exact threedimensional motion equations of an isotropic elastic body is used. Applying a peculiar integration method, previously developed by the authors of this paper, exact analytic solutions to the posed problem for the final time value are found. The results can be implemented in the production in designing special constructions, where there are impulsive effects on them. [ABSTRACT FROM AUTHOR]

When implementing variational methods for solving complex contact problems, there are difficulties, associated with non-convexity of minimized energy function of the system of interacting bodies and non-differentiability of this function at the desired point of its minimum. These difficulties do not allow to use gradient methods and convex analysis methods to minimize the energy function, therefore, numerical procedures for finding minimum points of such functions are cumbersome in program implementation and sometimes make it impossible to obtain the contact problem solution with sufficient accuracy. Non-variational method, based on using nonlinear operator equations with no difficulties during its implementation is proposed in the paper. Applying these equations allows to use modern achievements of nonlinear functional analysis, fixed-point theory of continuous mappings, theory of iterative methods for solving operator equations for both proving theorems of existence of solutions to contact problems, and developing effective iterative procedures for approximate solutions. Nonlinear boundary integral equations, used in this paper to simulate the contact interaction of elastic bodies, allow (unlike other similar equations) to take into account both the linkage and partial slip on the contact surface of bodies, and loading history of these bodies. Based on these equations, simple and efficient iterative procedures for approximate solutions to the contact problems are developed. A numerical solution of the contact problem on indenting the elastic sphere in the elastic half-space is obtained, and comparison of results with the known problem solution is made.

One of the ways of improving homogeneous catalytic oxidation of cyclohexane is the use of additives to industrial catalysts based on metals of variable valency. The analysis of literature sources has shown that alcohols that are formed in the process of oxidation and are able to form intermediate complexes with a catalyst have a significant impact. The effect of C2-C5 alcohol additives on the process of homogeneous catalytic oxidation of cyclohexane was studied in the paper. In the paper, the oxidation indices using binary catalytic systems of cobalt naphthenate - alcohol are given. The qualitative and quantitative effect of additives of monohydric and polyhydric alcohols on the process was defined, and their effects were compared. The dependences of the reaction rate on the nature of additives and the ratio between the components were determined. The optimal binary catalytic systems for the liquid-phase homogeneous catalytic oxidation of cyclohexane were selected, the use of which will allow improving the technical and economic production indices.

The vast majority of modern machine parts operate under cyclic loads, leading to, as a rule, failure, caused by the material fatigue. In this regard, the fatigue resistance of materials is one of the most important criteria for evaluating the structural strength of many parts of engineering structures. It is important that the process of exhaustion of cyclic life of metals, even at uniform stress state proceeds not uniformly in terms of volume of metal, but is initiated and develops more intensively in its surface layer. Under non-uniform stress state, role of the surface increases in connection with the presence of stress gradient. That's why, the most profound and systematic summarization of works, carried out in this direction, is aimed at performing a comprehensive analysis of changes in the properties of the surface layer of materials under active loading. However, investigated patterns of the surface microhardness change in the process of fatigue are usually qualitative and informative in nature. However, it should be noted that it is relevant to conduct studies, intended for obtaining quantitative estimates of the mentioned laws in order to develop fatigue failure criteria as a basis for improving calculation methods. This, in turn, requires developing a methodology for studying the surface layer behavior features and selecting the appropriate instrumental methods and tools. Analysis of a priori information indicates the need to investigate the microhardness, taking into account formation laws of the hardened surface layer, using different technological modes of surface treatment of metallic materials. In the present paper, the microhardness measuring method, characterized by a fairly high level of reproducibility of the obtained results and their experimentally justified correlation with the mechanical properties of the material is used. The developed method allows to determine the parameters of realized and residual life of the material. Thus, the research results, presented in the paper are of both scientific and practical interest. The authors have proposed the microhardness measuring methodology, characterized by a high level of reproducibility of the obtained results, which allows to determine the parameters of realized and the residual life of the material.

The paper considers the alternative possibility of obtaining saltforming nitrogen oxides by photochemical oxidation of atmospheric nitrogen using sources of incoherent radiation. It is shown that nitrogen dioxide, which is capable of twophoton absorption, in the process of which its photolysis is realized with the formation of singlet oxygen atom of O (1D) configuration and NO, can act as an oxidant. The latter, being oxidized, turns into NO2, and thus, the initial reagent is not lost in the system. In large-scale productions, it is rather difficult to carry out coherent (laser) radiation of reagents, therefore, the influence of incoherent irradiation on a product yield is studied in the paper, and mercury lamps with different radiation spectra were selected as sources. It was experimentally established and theoretically proved that maximum additional amount of NO is formed when using lamps DRT-125 with the operating range of wave lengths of 230-445,3 nm. The research results can be used in the chemical industry, namely in production of nitric acid for the transition to a non-catalytic ammonia-free method of obtaining NO, and in the production of adipic acid to reduce the consumption index on nitric acid, where flue gases contain molecular nitrogen, nitrous oxide and oxygen. Besides the economic aspect, the ecological aspect - reduction of greenhouse nitric (I) oxide emissions is observed in the paper. [ABSTRACT FROM AUTHOR]

The technology of forming wear-resistant composite electrolytic coatings on the nickel base is given in the paper. The CEC contained the filler of powders of silicon carbide of various factions: nanopowders of up to 50 nm, 5 (M5) μm, 20/28 μm, 40/50 μm and amorphous boron with the size of particles of about 1 μm to form solid solutions during further heat treatment. Accordingly, the following designations are accepted in the paper: Ni-SiCnano; Ni-SiC5; Ni-SiC28; Ni-SiC50. The setting to form the CEC was built which allows adjusting the resistance of the near-electrode layer of electrolyte, which in turn, allows forming the CEC in a wide range of technological parameters of electrolysis both on horizontal and vertical cathodes (Patent of Ukraine №55154 from 10.12.2010.). The study of cavitation-erosion wear resistance in hard water and in 3 % solution of NaCl showed that the CEC formed can be divided into 2 groups: group I - CEC of the composition Ni-SiCnano and Ni-SiC5 and group II - CEC of Ni-SiC28, Ni -SiC50. Thus, the CEC of Ni-SiCnano and Ni-SiC5 (group I) are the most effective to enhance cavitation-erosion wear resistance of parts which are operated in sodium chloride solutions, particularly in sea water (3 % solution of NaCl). Thermal annealing at 400 oC for 1-2 hours increases the cavitation wear resistance of the CEP Ni-SiCnano by 20 % in hard water and 30 % in NaCl solution due to the increase of micro-hardness, leveling of internal tension of coating and increase of corrosion resistance by reducing the electrochemical heterogeneity. Vacuum annealing of the CEC with particles of silicon carbide and boron at 1080-1090 oC allows to obtain dense and smooth coatings, the cavitation wear resistance of which increases on average more than 2 times as a result of formation of a solid frame from eutectic Ni-Ni3B and borides Ni3B.

The issue of enhancing the performance properties of petroleum, oil and lubricants (POL) using indifferent gas by an environmentally safe method is considered in the paper. The main purpose of the research was the improvement of the method of drying POL by indifferent gas, which lied in using exhaust gases of the truck tractor instead of the generator of indifferent gases, which are pre-purified from CO2 in the exhaust gas purification catalysts, which are also proposed to add to the circuit diagram. The improved scheme of drying petroleum, oil and lubricants by indifferent gas allows solving such problems as dehydration of POL, saving physicochemical and performance properties of POL, reduction of losses of oil products from vaporization, improvement of fire safety during the transportation of POL. The improved scheme, proposed in the paper, meets modern requirements for oil products purification systems, technical and environmental requirements, has low net cost of equipment. The research results can be applied in the operation of mobile equipment for storage and refuelling of POL and hydraulic fluids, as well as in the field of ecology and environmental protection. The research results can be applied by chemmotology experts, experts in the field of operation of equipment for refuelling and storage of POL, as well as ecologists. [ABSTRACT FROM AUTHOR]

The use of opportunities of systems of non-adaptive control, in particular, modal for high-quality management of linear dynamic objects is considered, and some results of our research in this field are given in the paper. The main objective of the research is to solve the problem of synthesis of stabilization law for a multidimensional control object based on the use of knowledge in the field of management, obtained from various sources, for the technological process of single-crystal growing by the Chokhralsky method on "GROWTH" setups. Current methods and means of ensuring the specified requirements to the management process imply distribution of matrix eigenvalues or transfer matrixes of a closed-loop system in the given points and areas, optimization of transients in the closed-loop system. The methods for stabilization of a condition of multidimensional object using the system, providing the implementation of the specified requirements to the management process on the basis of decomposition of the model of the growth process as a control object, are considered in the paper. The proposed method with the use of graphic representation of the sensitivity function for the analysis allows to obtain important information on high-quality management of the system for the obtained matrix components of this system. The algorithm of choosing the most appropriate matrix components for the model of the particular control object is presented. We propose to use this method for the increase in the accuracy of maintaining thermal conditions of the crystal growth, both in the stationary environment, and at the maximum perturbations of modes, with the purpose of improving the efficiency of management systems by modern growth setups in conditions of producing these single-crystals. The research results can be applied by specialists in the field of robust modal management of material, energetic and informational flows in the systems of management of modern technological processes, introduced into the technical environment of these technological processes.

The solution of the problem of factor analysis automation in the diagnosis and recognition of images is considered in the paper, and some results of our research in this area are given. The main purpose of the study is to develop an evolutionary method of factor analysis to find hidden dependencies in transactional databases. The use of modern methods of evolutionary search allows forming the groups of similar features. The issues of extracting factor groups from the specified transactional databases are considered in the paper for identifying new knowledge when solving the problems of diagnosis and recognition of images. The proposed method allows extracting the groups of qualitatively similar features from transactional databases. We propose to use the association rules to assess the equivalence of features terms that allows assessing the closeness of relationship between various features, making no demands to the input data and performing the factor analysis in transactional databases. The research results can be used by researchers dealing with the study and analysis of complex objects, processes and systems with the purpose to identify new knowledge, as well as in decision support systems for technical and medical diagnostics.

The paper gives the results of studying the effectiveness of a new method of phase separation using materials with capillary properties. It was found that processing of bentonite suspension by its conventional passing through a paper filter is accompanied by a low average filtering velocity and short operation time caused by intensive calmatation of pores by highly disperse particles. As a result, despite the relatively high efficiency of phase separation (residual content of bentonite particles in the filtrate - about 0.3 mg/dm3), the overall efficiency of separation is quite low because of the need for periodic restoration of filtering capacity of porous medium. A new method of phase separation, using materials with capillary properties, allows creating simple, cheap and effective devices for separating liquid and solid phases. Determining factors of separation process and their influence on the intensity of fluid motion in the porous medium were defined, comparative assessment of effectiveness of the proposed method with conventional filtration was conducted, basic parameters of separation with bentonite suspension processing were determined. It was also found that using the new method, the average velocity of fluid motion is twice higher than that of similar methods for conventional filtration. [ABSTRACT FROM AUTHOR]

The paper first examines the Hidden Abelian Group Action problem's complexity in quantum computing model. This algebraic problem is fundamental in determining the hardness of a one-way function constructed on the basis of commutative and locally commutative maps and ciphers. In fact, finding new one-way functions that will be resistant in quantum computing model is very important for modern cryptography. The main objective of the study is to assess the complexity of the Hidden Abelian Group Action problem by using a reduction to already known problems, such as the Hidden Subgroup problem and the Hidden Shift problem. In this paper, reduction of the Hidden Abelian Group Action problem to the Hidden Shift problem was first shown, and limitations that distinguish them were first demonstrated. As a result, on the one hand, the existing partial solutions to the Hidden Shift problem, and general Kuperberg's subexponential algorithm can be extended to the case of the Hidden Abelian Group Action problem. Moreover, more limitations give more chances to effective general solution to this problem. On the other hand, the reduction and similarity to a known challenge in quantum computing model also indicate the complexity of the Hidden Abelian Group Action problem, which leaves a chance for making a real stand one-way function in quantum computing model based on a locally commutative mapping.

The methods of processing the results of interlaboratory comparisons are described in the paper. The supplementary comparisons for national standards are carried out with the purpose of confirming measurement and calibration capabilities of the corresponding national metrology institutes. The Guideline on COOMET supplementary comparison evaluation does not take into account the presence of systematic error in the results of comparisons. The Guidelines on "Comparisons of groups of instruments for calibration of the same accuracy level" (MI 1832-88) take into account a systematic component of the measurement error, but the results of comparisons are not verified for consistency, which is an objective confirmation of stated uncertainties. Thus, we propose to combine these two methods for objective demonstration of measuring data reliability. To confirm the method selected for processing the comparisons results, an experiment was conducted, comparisons of voltmeters of one accuracy class with higher accuracy class were made. The results of comparisons and their processing by the proposed combined method are given in the paper. Thus, the proposed method allows evaluating the systematic component of uncertainty and its correction, hence, the laboratory comparisons data are recognized as such that confirm given uncertainties.

The objective of the paper is the scientific substantiation of technologies for producing new kinds of fruit-berry ice-cream and fine-dispersed additives using a cryogenic "shock" freezing and low-temperature grinding for producing healthy products with high content of BAS. In the paper the quality of frozen fine-dispersed additives made by the innovative technology in the form of nanostructured puree was compared with feedstock in regard to BAS content. It is shown, that under conditions of feedstock freezing and low-temperature grinding, accompanied by cryogenic destruction and mechanical activation processes, BAS is more fully extracted from a biopolymer-bound into a free state. The increase rate of BAS extraction depends on its kind and varies from 1.6 to 2.9 times with respect to fresh feedstock. Technology, technological scheme and three formulations of new fruit-berry ice-cream ("Vitaminchik", "Limonchik", "Tropik") were developed, with their quality analysis in respect to BAS content. It is shown that new healthy fruit-berry ice-cream is better than the native analogues by its chemical composition and competes with the best foreign analogues, as it contains a great amount of BAS: vitamin C, phenol compounds, tanning substances, organic acids, pectin and mineral substances. Thus, 100 g of the fruit-berry ice-cream "Vitaminchik" contains the daily norm of vitamin C, "Limonchik" and "Tropik" have half of the daily norm of this vitamin. Moreover, new kinds of ice-cream have a significant content of phenol compounds, tanning, pectin and mineral substances, etc. The quality of IR spectrums of new kinds of ice-cream was compared to their analogue ("Snihovyk" fruit-berry ice-cream, "Khladoprom" PrJSC). The final result of the work is the development of the Scientific Research Project on nanostructured puree and new kinds of fruit-berry ice-cream. Furthermore, new kinds of ice-cream have passed degustation and approbation in production environment at Kharkov enterprises ("Khladoprom" PrJSC, "Polus LTD" SUIS LLC). [ABSTRACT FROM AUTHOR]

Despite many publications concerning the features of the boiling process in a limited volume on smooth and extended surfaces, the majority of them deals with the forced liquid flow. At the same time, there is a need for studying the boiling process on porous surface in a limited space with natural current of heat carrier. The paper gives the results of experimental studies of the boiling process, which indicate the influence of the free space size on the heat dissipation intensity during the boiling on smooth and porous surfaces. Based on the experimental data analysis and the results of a series of visual studies, a physical model of the process has been suggested. In addition, the paper gives a number of systems of differential equations with boundary conditions, which can be used for constructing a mathematical model of the boiling process on the porous structure in a limited volume.

The paper considers the causes of poor quality of Ukrainian roads. One of possible solutions is using the emulsion technology instead of traditional "hot on hot" methods of paving and repair of roads. In addition to prevention of bitumen obsolescence tendency using emulsions has a number of significant advantages (lower energy costs, the ability to pave on a wet basis). The paper proves the possibility of bitumen emulsions production under the SSU.2.7-129:2006 based on surface-active substances produced at the JSC «FOSP«Barva». These emulsions, containing 50% of bitumen and 1-3% of surface-active substances "Barvoteks-30", "2K", "Cationic fat" and "Ripoks-3", meet the above standard by their sieve residue homogeneity, storage stability after 7 and 14 days and t relative viscosity at 25 °C.

The paper deals with improving the superposition principle of substance concentration for watercourses. The substance superposition principle in watercourses arises from the linearity of turbulent diffusion equation and its boundary conditions. When using the superposition principle of substance concentration in water courses, usually only point sources of substance are taken into account, neglecting diffuse (distributed along the watercourse) sources and substance-containing effluents. Diffuse sources of substance are formed by the surface and ground waters getting to the watercourse as well as atmospheric precipitation on the water surface. Diffuse effluents are connected with the processes of water filtration through the watercourse bottom. The paper justifies the use of the superposition principle of substance concentration for watercourse with regard to the diffuse sources and substance-containing effluents. The formulas were obtained which reflect the superposition principle of non-conservative substance concentration in watercourse and simplify the calculation of two-dimensional field of substance concentration in view of point and diffuse sources and substance-containing effluents. The formulas allow improving the accuracy of calculations of water quality in watercourses. [ABSTRACT FROM AUTHOR]
