Proposed and substantiated a flow chart of processing voice traffic by technical means air analog radio in the range 118-137MHz for conditions when it is necessary to ensure a high level of protection of voice messaging. Technical implementation of the proposed scheme allows you to modify the existing analog radio resources without changing the design of the aircraft VHF radio and not breaking the rules of the radio traffic. In general, a number of additional devices in the (vocoder + crypto coder + frequency phase manipulator), it is desirable to perform as a single device and connect it to the interface point transmission equipment between the microphone and the modulator carrier frequency of the radio signal. A device, that implements the circuit (frequency-phase demanipulator + decoder + crypto synthesizer vocoder), need to be connected to the receiving side between the output of the demodulator and the input of the phone by person who receives voice messages. In this case, a display panel of standard equipment is sufficient to add only a voice communications mode switch (protected \ no protection) [ABSTRACT FROM AUTHOR]

It is established that in comparison with other polymeric binders, the processes of obtaining the epoxy-amine compositions, used in construction, meet 8 of 12 principles of "green" chemistry. It is shown that the use of low-molecular weight substances as acid catalysts of the curing reaction reduces the value of E-factor by one order and the value of atom efficiency of the process by two orders. It is experimentally proved that the disperse mineral fillers, which have hydroxyl groups with various functions of acidity on the surface, can be used for the acceleration of reaction of cross-linking in the production of polymeric construction materials based on the epoxyamine compositions. This will allow to improve the environmental safety of the preparation, application, use and utilization of these materials by the exclusion of toxic and environmentally hazardous to humans and biosphere low-molecular weight substances.

Purpose. To obtain analytical dependencies for the precise calculation of the stator current of a frequency-regulated three-phase short-circuited induction motor and to estimate the components of its main electrical power losses, which are spent on the transportation magnetic power losses (to the magnetization circuit) and additional power losses (through the motor air gap), as well as with using the obtained refined dependencies to research the electromagnetic processes and energy modes of the frequency-regulated induction motor when its speed and load change. Methodology. The method of generalized vectors is used for the refined calculation of the electromagnetic processes and energy modes of the frequency-regulated induction motor. Results. Based on the catalog data and parameters of the induction motor’s equivalent replacement circuit, also the specified values of its useful rotational torque and speed, refined analytical dependencies were obtained for the calculation of the main electromagnetic power losses of the frequency-regulated induction motor, which take into account the influence of all types of power losses, which present in it, as well as – power losses spent on transporting magnetic losses (to the magnetization circuit) and additional losses (through the air gap of the motor). With the help of the obtained dependencies, the energy modes (including main power consumption and electromagnetic power losses, efficiency factor, power factor) of the frequency-regulated induction motor in the driving and generator modes of its operation in relation to the first (at speeds not higher than the nominal) and the second (at speeds above the nominal) speed control zones for the operating ranges of the motor useful rotational torque and speed changes were calculated. Originality. A refined analytical calculation dependence has been obtained for determining the active projection of the generalized stator current vector of a frequency-regulated induction motor, which takes into account the presence of additional power losses and the component of electrical losses caused by the transportation of additional power losses through the air gap of the motor; an analytical dependence is also proposed for determining the increment of the mentioned active projection, which is due to the transportation of magnetic power losses to the motor magnetization circuit. Practical value. Analytical calculation dependencies are proposed for the quantitative assessment of errors (as a percentage of mentioned values) in steady-state modes for determining the main electromagnetic power losses of the frequency-regulated induction motor, caused by the absence (in comparison with relevant studies from known publications) of taking into account additional and magnetic power losses, as well as – the influence of electrical component losses caused by the transportation of the mentioned power losses through the air gap or to the magnetization circuit of the motor, respectively.

The issue of international trade is undoubtedly one of the most important foundations of the contemporary processes of internationalization and globalization. However, before they appeared, other events had to take place, the cumulative effects of which led to the formation of today's structure of the world economy understood as a specific system of connections between the main actors of international economic relations, i.e. international organizations, states and enterprises/corporations. It is worth, therefore, before proceeding with the analysis of current problems, to make a synthetic indication of the most important issues from modern economic history relating to the issues of international trade. Man as a farming being, motivated to act by his needs, constantly strives to satisfy them. Streszczenie Problematyka handlu międzynarodowego jest jednym z najważniejszych fundamentów współczesnych procesów internacjonalizacji i globalizacji gospodarki światowej. Zanim jednak one się pojawiły, musiały nastąpić inne zdarzenia, których skumulowane skutki doprowadziły do ukształtowania się dzisiejszej struktury gospodarki światowej rozumianej jako specyficzny system powiązań pomiędzy głównymi aktorami międzynarodowych stosunków gospodarczych, tj. organizacjami międzynarodowymi, państwami oraz korporacjami. Warto zatem syntetycznego wskazania najważniejszych zagadnień współczesnej historii gospodarczej, odnoszących się do problematyki handlu międzynarodowego. W artykule wykorzystano analityczne i syntetyczne metody badawcze.

The purpose of this article is to establish the directions of state regulation of foreign exchange, highlight the features of state regulation of foreign exchange, and determine the prospects for improving the mechanism of state regulation of foreign exchange in Ukraine. It has been determined that the ED is a complex complex type of activity that includes various objects and can be stratified into segments taking into account a number of criteria and features. At the same time, what is in demand is not the study of individual areas of regulation of foreign economic activity, but the analysis of their interaction. During the implementation of the FEZ, the achievement of the fundamental goal is significant - such activity should become a source of increasing national income and sustainable development of the economy. This has a perspective only in the course of solving tasks to achieve this goal, which is unattainable without a balanced and effective state administration. It has been proven that the State regulation of foreign trade includes a set of measures that have a legislative, executive and control nature, and are aimed at improving foreign trade in the interests of the country's economy. This system provides for the creation of the necessary conditions and mechanisms for the effective interaction of business entities within different states and at the international level. It has been established that the main directions of foreign economic activity are entrepreneurial activity, foreign trade, provision of various services, financial and credit operations, scientific and technical cooperation with foreign enterprises, etc. Regulation of these types of activities is carried out by the state through its bodies. Also, non-state subjects of economic management are involved in the regulation of foreign exchange, including: stock exchanges, chambers of commerce, associations, etc. The regulation of FEZ takes place together with FEZ subjects themselves on the basis of agreements concluded between them on the coordination of actions. It was emphasized that the essential components of the FED management mechanism are the systematic monitoring of the external and internal environment, the analysis and assessment of the state and development prospects of the FED, the development of tactical and strategic plans. It is legitimate to claim that the active digitization of the economy can provide advantages in the implementation of foreign trade in Ukraine.

The subject of this study is methods for improving the efficiency of semantic coding of speech signals. The purpose of this study is to develop a method for improving the efficiency of semantic coding of speech signals. Coding efficiency refers to the reduction of the information transmission rate with a given probability of error-free recognition of semantic features of speech signals, which will significantly reduce the required source bandwidth, thereby increasing the communication channel bandwidth. To achieve this goal, it is necessary to solve the following scientific tasks: (1) to investigate a known method for improving the efficiency of semantic coding of speech signals based on mel-frequency cepstral coefficients; (2) to substantiate the effectiveness of using the adaptive empirical wavelet transform in the tasks of multiple-scale analysis and semantic coding of speech signals; (3) to develop a method of semantic coding of speech signals based on adaptive empirical wavelet transform with further application of Hilbert spectral analysis and optimal thresholding; and (4) to perform an objective quantitative assessment of the increase in the efficiency of the developed method of semantic coding of speech signals in contrast to the existing method. The following scientific results were obtained during the study: a method of semantic coding of speech signals based on empirical wavelet transform is developed for the first time, which differs from existing methods by constructing a set of adaptive bandpass Meyer wavelet filters with further application of Hilbert spectral analysis to find the instantaneous amplitudes and frequencies of the functions of internal empirical modes, which will allow the identification of semantic features of speech signals and increase the efficiency of their coding; for the first time, it is proposed to use the method of adaptive empirical wavelet transform in the tasks of multiple-scale analysis and semantic coding of speech signals, which will increase the efficiency of spectral analysis by decomposing the high-frequency speech oscillation into its low-frequency components, namely internal empirical modes; the method of semantic coding of speech signals based on mel-frequency cepstral coefficients was further developed, but using the basic principles of adaptive spectral analysis with the help of empirical wavelet transform, which increases the efficiency of this method. Conclusions: We developed a method for semantic coding of speech signals based on empirical wavelet transform, which reduces the encoding rate from 320 to 192 bps and the required bandwidth from 40 to 24 Hz with a probability of error-free recognition of approximately 0.96 (96%) and a signal-to-noise ratio of 48 dB, according to which its efficiency is increased by 1.6 times as compared to the existing method. We developed an algorithm for semantic coding of speech signals based on empirical wavelet transform and its software implementation in the MATLAB R2022b programing language.

Статтю присвячено дослідженню інститу­ту охороні права власності в адміністративному праві. Правовий інститут охорони права влас­ності в адміністративному праві розглянуто як сукупність адміністративно-правових норм, що регулюють однорідні суспільні відносини, пов'я­зані з охороною права власності. В системі адмі­ністративного права вони утворюють самостійну відокремлену групу, пронизану внутрішньою єд­ністю, зі спільною метою - забезпечення цілісно­го ефективного регулювання суспільних відно­син, пов'язаних з охороною права власності, що допускають можливість застосування до фізичної або юридичної особи заходів адміністративної відповідальності за вчинення цією особою пра­вопорушень, що посягають на власність. Встановлено, що: 1) інститут охорони права власності, як системне, цілісне утворення, являє собою єдність закономірно розташованих і таких, що перебувають у взаємному зв'язку, елементів, до яких ми віднесли джерела, об'єкти правовід­носин, а також спеціальних суб'єктів, діяльність яких спрямована на організацію відповідної охо­рони прав власності за допомогою застосування адміністративно-правових заходів та засобів; 2) Інститут охорони права власності в адміністра­тивному праві оперує універсальними адміністра­тивно-правовими заходами та засобами. Вказана універсальність полягає в тому, що вони поєд­нують «силу» державних структур, з якими вони зазвичай асоціюються, і які припускають пряме застосування різних заходів державного приму­су з превентивним впливом. Їх комбіноване ви­користання дає змогу якнайповніше та всебічно захистити право власності на галузевому рівні. Констатовано, що державне регулювання сфери охорони права власності в Україні нале­жить до широкого кола відносин, що становлять предмет як цивільного, кримінального, так і ад­міністративного права. В правовій системі Украї­ни створено цілий комплекс інститутів з охорони права власності. В своїй сукупності вони утворю­ють правову основу державної охорони власно­сті. Водночас застосування органами виконавчої влади, під час охорони права власності, адміні­стративно-правових заходів та засобів є найе­фективнішими у співвідношенні «витрачені кош­ти - отримані результати від їх використання».

The purpose of the article is to establish the peculiarities of the implementation of the principles of good governance in Ukraine and their impact on the development of democracy in the country. It was established that in foreign sources, the concept of good governance is defined as an institutional environment where citizens interact with government structures and employees; as effective, transparent and responsible government management of public affairs, including the involvement of representatives of civil society in achieving common goals of social, economic and cultural development. It was determined that an important component of effective governance is the observance of democratic principles, which includes active public participation and transparency in state activities. This will contribute to the stable economic and social development of Ukraine. To achieve this goal, it is necessary to involve all interested parties at the state and local levels, focusing on the principles of good governance. It has been proven that in the current conditions and in the future, the problems of social consolidation, tolerance, achieving consensus and trust between social, national and religious groups will become the main issues. The problem of trust in power, economic and legal institutions will also remain high. The Ukrainian government will be forced to make unpopular decisions in difficult conditions that will depend on the socio-economic situation and the demands of society. This requires the mechanisms of deliberative democracy, which will promote inclusiveness, reasoned discussions and conflict resolution. It is proven that two directions can be considered to strengthen democracy in Ukraine and strengthen good governance: improvement of existing mechanisms of public discussions by adding elements of deliberation, as well as research, adaptation and implementation of new mechanisms. Special attention should be paid to systematic dialogues with institutions of civil society, which can be useful in solving complex social problems.

In the mining and industrial regions of Ukraine, a large amount of mine and quarry waters is formed. Due to high mineralization, they cannot be discharged into natural hydrographic objects without deep processing, including demineralization. Most of such waters are significantly contaminated with concentrates of sulfides and dissolved iron compounds, which hinder their further purification. At the same time, thermal power plants located in these regions consume a significant amount of scarce drinking water for their needs. Deep processing of mine and quarry waters allows to clean them and obtain feed water for heating systems, boilers of TPPs and CHPs. A method of obtaining stable inert titanium-based anodes with an active coating of PbO2, which do not contain noble metals and their compounds, has been developed. The method consists in protecting titanium from passivation with an oxide film by thermally applying a MnO2 coating, and later applying to the base with this coating a thin layer of PbO2 from an alkaline complex electrolyte containing 2.5 mol/dm3 NaOH, 0.6 mol/dm3 EDTA, ethylene glycol additive and is a saturated PbO. The main 3–5 mm thick layer of coating is applied from the nitrate electrolyte, which includes Pb(NO3)2 1 mol/dm3, Cu(NO3)2 0.4 mol/dm3, Al(NO3)3 0.2 mol/dm3 and the gelatin additive. A method of extending the service life of an alkaline electrolyte by reduction of Pb (IV) compounds during the contact with the active surface of metallic plumbum is described. The conducted resource tests of this anode for 1400 hours proved its stability when processing solutions containing a mixture of sodium sulfate and sodium chloride. On the basis of this anode, the technology of electrochemical deironing of mine waters and removal of sulfides from them before demineralization was developed and experimentally tested. This technology is the only possible method of reagent-free iron removal and removal of sulfides from waters with high mineralization. Such anodes significantly expand the scope of application of electrochemical processes. They can be used not only for water treatment in thermal power generation, but also for the treatment of wastewater of various mineral and organic composition, chemical and technological processes for obtaining oxidants, etc.

Concept of Monoverse, which corresponds to the existing broad interpretation of the second postulate of the special theory of relativity, is not consistent with the modern astrophysical reality — existence of the dark matter and the dark energy, the total mass-energy of which is ten times greater than the mass-energy of the visible universe (which has been considered as the entire universe until very recent) . This concept does not allow to explain their rather unusual properties — invisibility and lack of baryon content — which would seem to even destroy the very modern understanding of the term ‘matter’. However, all numerous alternative concepts of Multiverses, which have been proposed until today, are unable to explain these properties of the dark matter and dark energy. This article describes a new concept: the concept of the hidden Multiverse and hidden Supermultiverse, which mutual invisibility of parallel universes is explained by the physical reality of imaginary numbers. This concept completely explains the phenomenon of the dark matter and the dark energy. Moreover, it is shown that the dark matter and the dark energy are the experimental evidence for the existence of the hidden Multiverse. Described structure of the hidden Multiverse is fully consistent with the data obtained by the space stations WMAP and Planck. An extremely important property of the hidden Multiverse is an actual possibility of its permeation through stargate located on the Earth.

Purpose. The paper is devoted to the detailed analysis of interrelations at the contact point of friction pair «contact wire – current collector insert».

It was proposed to equip the pantographs slide with current collector elements using special scheme and to develop a specialized research facility, which will be possible to conduct studies of the interaction of the friction pair «contact wire – current collector insert». Originality. In the course of the study the current collector inserts the sharp structural heterogeneity and fluctuations of the density of the material along the length of the insert were established. The dependence between hardness of inserts and electrical resistivity was established. It was analyzed and concluded about the need to reduce the values of the normal range of hardness. Based on the results of the research, the experimental dependences were obtained and proposed the method for sorting carbon current collector inserts for the structural parameters. Practical value. The obtained results of coal current collector inserts define the need to use method for sorting the coal current collector inserts and the use of a special scheme for equipping pantograph slide. It will allow optimizing their work, knowing the limitations for edges in exploitation and the type of the objective function that should be achieved. The proposed measures can reduce the intensity of the electrical and mechanical wear of materials friction pair «contact wire – current collector inserts». The use of specialized research facility for the study of the friction pair, will allow carrying out the studies to determine the intensity of wear of contact surfaces of the pair of friction and the coefficient of friction at various external factors.

Purpose. The paper is aimed to determinate the main ways of increasing resource efficiency and exploitation of coal current collector surface inserts of speed electric rolling stock. Methodology. The research is based on the technique relies on the use of theory regulations of technical systems reliability, electromechanical processes, theory of statistics. Findings. The existing approaches to the production of current collector surface inserts in Europe and Ukraine were considered, a number of information sources was analyzed. The most effective ways of increasing current carrying capacity and wear resistance of current collector elements were determined. It has been established that the existing system for determining the quality of manufacturing of current collector elements have a number of drawbacks that make it difficult to control the input and makes diagnosing current collecting elements in operation impossible. On the basis of the facts, for the needs of the locomotive depot, we propose a new booth allowing avoiding the existing difficulties with diagnosing of current collector elements. During the study were established pervasive transgressions of technological standards of service pantographs. Originality. Based on the results of operational research carried out on the basis of the locomotive depot, obtained depending, based on which, it is proposed to introduce an operative diagnosing system of the current collector elements state during operation. In the course of a comparative analysis of existing and perspective development directions of current collector elements with high load current carrying capacity and durability, were definited constructive conditions for the optimal ratio is inserts. It was established that a significant proportion of failures occur due to imperfect maintenance system for which, on the basis of operational data, recommendations were developed. Practical value. Obtained results of the information sources analysis determine the need to implement coal inserts copper component in material, which will increase the load current carrying capacity of the current collectors. The numerous shortcomings of existing diagnostic systems carbon of current collector inserts skids pantographs were established, the solution of them should be the basis for the development of new means and diagnostic systems of current collector elements. It can improve service life of inserts and arrange culling of substandard of current collector inserts. The imperfect system maintenance of pantographs was established. The requirements increasing to this system will significantly reduce the amount of breakages caused by an increased transitive resistance in the «insert – pantograph».

Features of sporadic decameter solar radio emission associated with some active regions according to observations made with radio telescope UTR-2 on August 1, 2014 are considered. Analysis of characteristics of type IV bursts, fiber-bursts and type III bursts, which were preceded and followed by type IV bursts, was carried out. Similarity of origins of fiber-bursts and type III bursts. By the frequency drift rate, they are distributed by statistically independent groups. Each group of bursts and that of type IV bursts were identified with radio emission from a particular active region. The plasma parameters in these regions and their variations while generating type IV bursts are estimated.

Theoretical study of important bulk properties of nuclei far from stability such us the nuclear skin and its correlation with the density dependence of the symmetry energy in uniform matter is reviewed. The formation of neutron skin and its evolution with an increase of the neutron number is investigated on the basis of a self-consistent deformed meanfield Hartree-Fock method using density-dependent Skyrme force sand pairing correlations in BCS approach. We study isotopic chains of Ni, Kr, and Sn nuclei and consider all the experimentally observed isotopes from neutron-deficien to neutron-rich ones. Various definition of the neutron skin thickness based on the differences between neutron and proton radii as well as on comparison of the tail soft he neutron and proton density distributions have been tested. The effects of deformation on the neutron skins in even-even deformed nuclei are discussed on the example of Kr isotopes. The symmetry energy, the neutron pressure and the asymmetric compressibility of spherical Ni, Sn, and Pb and deformed Kr and Sm neutron-rich even-even nuclei are calculated within the coherent density fluctuation model using the symmetry energy as a function of density within the Brueckner energy-density functional. The correlation between the thickness of the neutron skin and the characteristics related with the density dependence of the nuclear symmetry energy is investigated for isotopic chains of these nuclei. The mass dependence of the nuclear symmetry energy and the neutron skin thickness are also studied together with the role of the neutron-proton asymmetry. The studied correlations reveal a smoother behavior in the case of spherical nuclei than for deformed ones. We also note that the neutron skin thickness obtained for 208Pb with SLy4 force is found to be in a good agreement with the recent data. In addition, we analyse the existence of peculiarities of the studied quantities in Ni and Sn isotopic chains that are not present in the Pb chain.

Narrow ring lane of interstellar medium is considered as two-dimensional incompressible self-gravitating liquid with given differential flow. Variability of the surface density and the ring curvature at the distances of the order of its width are also ignored. The stability of such ring lane is investigated in linear approximation. The gas-dust ring has two types of instability: Jeans instability at long wavelength and hydrodynamic instability at short ones. The effect of galaxy rotation is found to be able to remove the both instabilities provided the approximate values of the parameters chosen.

Lyapunov’s method is applied to the problem of stability of stellar systems. The stability criterium is obtained for the particular case, when the phase density depends only on the energy integral.

The problem of determination of distribution of equilibrium angular velocity of gas-dust matter flow in a axisymmetric gravitational potential under the density distribution specified is considered.

The problem of nonlinear stability of a circular cylinder and Maclauren disk with respect to non-radial oscillations, which give to the stellar system an elliptical form and maintain the space density constant in the disturbed state, is discussed. Time-dependent phase invariants are determined. Under the condition of their existence the total energy of two-dimensional models is minimized. For non-linear oscillations considered, stability conditions in form of limitation from above of the centroid velocity Ω are found, viz for a cylinder Ω < 1 and for a disk Ω ≤ (125/486)^1/2 (in units of circular velocity) what coincides with the linear approximation data.

Self-gravitating conservative systems having internal flows are investigated. The sign of energy of oscillations and stability criterion of rotating systems are analyzed.

The stability is studied with respect to longitudinal perturbations of an infinite cylinder homogeneous along z axis. The problem is reduced to the one-dimensional one by the proper choice of the model. It is shown that the cylinder is unstable for any dispersion of the velocities (σ^2). The asymptotic estimate of critical wavelength is found for several density distributions. It shows that the critical wavelength increases so that can hardly play any role in physical applications.

Propagation of nonlinear adiabatic waves in a gas is shown to be possible due to self-gravitating of the gas. Hydrodynamic equations together with the Poisson’ equation lead to stationary solutions if the problem considered is not one-dimensional.
