Published: July 2021

Longevity in life span of city dwellers depends upon the quality of ambient air, which is often compromised due to urbanization. In this context, since independence, Bengaluru has rampantly grown with elevated air and automobile pollution levels. Ambient Carbon Monoxide [CO], which is considered to be the most dangerous criteria air pollutant, however has insufficient research/literature for the city of Bengaluru. To plug this gap, the pre-sent study engages a detailed examination for Temporal and Spatial Map-ping variation of Ambient ‘CO’ concentration in different wards of Bengaluru using calibrated Digital ‘CO’ sensor. The methodology involved primarily an intensive literature review followed by reconnaissance survey for fixation of monitoring stations about each ‘ward’. Further at these observatories, extensive primary data collection was ensued at periodic and regular intervals. The objective serves to delineate the most critical and non-critical places in Bengaluru to incorporate remedial measures. Startling 400+ violations with potential of triggering congestive heart failure, impaired performance in time discrimination, shortened time to angina response and vigilance decrement were observed. Sustainability measures conclude the study.

Authors: Susnea Ioan , Pecheanu Emilia , Cocu Adina
Published: July 2021

In the context of the alarming news about climate changes, resource depletion, ecological disasters, and demographic trends, the interest of the researchers and the scientific literature on topics related to sustainability grew exponentially in the past two decades. In 2020 only, the number of publications indexed in the Web of Science (WoS) having the keywords “sustainability” or “sustainable development” in the topic was higher than 42,000. Facing this flood of literature, the present work aims to ease the effort of locating relevant studies about the applications of Agent-based Modeling and Simulation (ABMS) in the research of environmental sustainability. This goal is accomplished by: (a) providing a comprehensive bibliography of recent relevant articles on this topic, (b) identifying the most popular domains of application of ABMS in this field, and (c) building a list of the available simulation tools. We found that most of the selected studies (52%) are designed for management related acticities (decision support, policy making etc.), the application domain addressed by the largest number of articles (27%) is agriculture and related activities (pastoralism, hunting, fishery, and forestry), and the most popular simulation platform is NetLogo (15%).

Authors: Yakup Abdurishid
Published: July 2021

The Old Uyghur fragment U 3901 (T.M. 96) kept in the Berlin Turfan collection recently published by Professor Peter Zieme is not from the translation of the Buddhāvataṃsaka-sūtra in eighty volumes, as he argues, but represents part of an invocation of bodhisattvas found in the Da fangguang fo huayan jing haiyin daochang shi zhong xingyuan chang bianli chanyi 大方廣佛華嚴經海印道場十重行願常徧禮懺儀, an important monument of late Tangut Buddhism. It is a new text which is not known yet in the Old Uyghur Buddhist literature. This paper presents an analysis of the text and its new edition.
A historical morphology of Western Karaim: The -a jez- ~ -a ez- approximative
Authors: Németh Michał
Published: July 2021

Karaim is often treated as an exceptional Kipchak Turkic tongue in which certain, otherwise widespread Turkic verbal constructions are not present. Philological discoveries of recent years show, however, that some of these categories did exist in Karaim. As a response to this issue, the present article documents the Western Karaim equivalent of the Tkc. -a jaz- approximative construction. It is based on 18th- and 19th-century Biblical texts which are then juxtaposed with both phonetically and morphologically atypical 20th-century data. This contribution is part of a series of works describing Karaim grammatical categories hitherto undocumented in the scholarly literature.

Published: July 2021

This study aims to develop alternative steering models for the EV bus. The EV bus uses its energy source from the main 384 VDC 300 Ah battery and the secondary battery with a capacity of 25.8 VDC 100 Ah. The use of energy in this electric bus is divided into the main components, namely the BLDC motor as the main drive of 200 kW, 15 kW of air conditioning, 7.5 kW of hydraulic power steering, a compressor for the air braking system of 4 kW, and accessory components. The other is 2.4 kW. It is expected that this 7.5 kW electric power can be reduced by an electric system by up to 20 %. This research will study the steering system with an electric power system (EPS) to convert the hydraulic steering system (HPS). With this EPS system, it is hoped that controlling the vehicle’s motion towards the steer by wire will be easier. Initially, data were collected from the types of large vehicles from various well-known brands about the steering system used. A large commercial vehicle that purely uses EPS is not yet found. The model developed for EPS on this electric bus is through the reverse engineering method by redrawing all the components involved in the previous steering system. Because this type of EV bus is included in the upper mid-size class, this paper proposes two new EPS models, namely the addition of an assist motor on the drag link and on the steering rack. The links involved in this system are wheel drive, steering column, lower steering column, rack and pinion gear, assist motor, drop link, drag link, drop link extension, drag link extension, tie rod, knuckle, kingpin, tire, axle beam and several others. The values of stiffness, inertia, and damping of each link will affect the driver’s torque and the assist motor as a wheel speed function on this electric bus. The steering structure of the EV bus consists of a truss structure and a frame structure with a kinematic structure consisting of two four-bar linkages joined together

This paper suggests a method to search for an incoming object in order to identify its unambiguously, based on the integration of information spaces into intermediate unified information space. At the same time, the incoming object identification process involves appropriate attributes.
This paper describes the process of information object arrangement within a unified information space that forms for a set of dynamically changing objects. It should be noted that each subject in the set collects information about the environment, including interaction with other objects. In the process of forming a unified information space, the information system collects information from data sources that are represented in different formats. The system then converts this information and forms a unified information space, thereby providing users with information about objects.
A two-tier system of connections at the global (cloud) and local (fog) levels of interactions has been considered. At the same time, it should be noted that a unified information space formation requires the implementation of tools to support the transformation of information objects; that necessitates the implementation of translators ‒ special converters at different levels.
A method to combine information spaces into an intermediate unified information space has been proposed; analysis was performed to determine the time and efficiency of the search for incoming objects within it.
It was experimentally established that the more parameters that describe an information object, the less the time to identify an object depends on the length of the interval.
It has also been experimentally shown that the efficiency of finding incoming objects tends to be a directly proportional dependence while reducing the length of the interval and increasing the number of parameters, and vice versa

Authors: Velychko Oleh , Hrabovskyi Oleh , Gordiyenko Tetyana , Volkov Serhii
Published: July 2021

The problem of increasing the reliability and competitiveness of products in all sectors of the national economy can be solved only on the basis of obtaining complete and reliable measurement information. This is facilitated by modern measuring instruments (MI), which are complex hardware and software systems. The relevance of the study is due to the fact that modern MI need an effective assessment of their quality at all stages of the life cycle (LC). This requires the development of appropriate assessment methods both at the stage of production and operation of MI.
The expediency of using the process approach to MI LC stages and its advantages over the functional approach were proved. The process approach allows more effective assessment of MI quality indicators at different LC stages and is compatible with the construction of modern quality management systems.
Mathematical modeling was carried out, a set process model of the MI LC was developed and its representation as a process V-model was carried out. This allows studying the interaction of processes of all MI LC stages and performing process quality management at all MI LC stages.
Mathematical modeling was carried out, a set process model of evaluation of quality indicators of MI LC stages was developed and its representation as a process V-model was carried out. This allows evaluating quality indicators of the MI and its components throughout the MI LC.
Recommendations for the use of international standards were formulated, in particular for project management planning, measurement processes, system requirements throughout the MI LC, risk analysis and management at the LC stages. This should help increase efficiency in achieving the planned results at all stages of the MI LC

Published: July 2021

This paper has substantiated the prospect of modeling the processes of separating grain mass into fractions as one of the tasks in the production of high-quality seed material. It has been determined that this could optimize the parameters of separation processes and design new working surfaces for its implementation. It is noted that modeling should take into consideration the influence of the structural and kinematic parameters of grain cleaning machines, the physical and mechanical properties of raw materials, the intralayer processes and forces.
The reported theoretical study has improved the mechanical-mathematical model of grain mass separation in a pseudo-fluidized bed according to its density. The model establishes a relationship between the effective coefficient of dynamic viscosity and the density of particles in the discrete and continuous phases and the volumetric concentration of discrete phase particles. At the same time, the porosity of a fluidized bed has been accounted for, as well as the longitudinal and transverse angles of inclination of the base surface to the horizontal plane, the amplitude and frequency of oscillations of the particles of the continuous phase; the direction angle of oscillations relative to the perpendicular to the base surface.
The adequacy of the improved mechanical-mathematical model has been confirmed by comparing the experimental and theoretical results of grain mass fractionation modeling. It was found that the differences in the density values of the separated fractions of GM did not exceed 7...8 %, that is, they were within the margin of error.
It has been established that the improved model of grain mass separation in a fluidized bed could be used to determine the rational values for the parameters of a pneumatic sorting table that is used for the fractionation of the corresponding seed material. The initial data, in this case, are the density of the continuous and solid phases of grain mass, the friction coefficient of the seeds, and the equivalent radius of the particle. The result of modeling is the rational values of the amplitude and oscillation frequency of the working surface of the pneumatic sorting table, and the angles of inclination of the working surface

Published: July 2021

This paper reports the improved model design of an auger thermo-radiation dryer for drying plant-derived pomace under a low-temperature mode (35...80 °C) to the resulting moisture content at the level of 8...13 % of solids. The dryer has an adjustable speed of auger rotation (3...4 min–1), of airflow (0.05...0.09 m/s), and is characterized by the uniform distribution of heat flux. It is equipped with an energy-saving two-circuit complex that utilizes secondary energy to heat primary air from 21.1 °C to 28.9 °C. The use of Peltier elements, installed at the heating technical surface of the dryer's auger, makes it possible to convert thermal energy into a low-voltage supply voltage for the autonomous supercharger and exhaust fans.
The duration of pomace drying in the model structure of the auger thermo-radiation dryer has been determined, in particular tomato pomace, with an initial content of 75 % of solids, which is 107 min. For apple pomace whose starting content of solids is 65 %, it is 98 min. For comparison, the duration of the convective drying of tomato pomace (75 % of solids) is 120 minutes. The drying was carried out at a temperature of 60 °C to the resulting moisture content of 10...12 % of solids. Organoleptic evaluation on the example of tomato pomace confirms the effectiveness of structural solutions in the auger dryer compared to the convective technique.
The results reported in this study could create conditions for the further design and implementation of the proposed structure of thermo-radiation dryer for drying plant-derived pomace involving an altered heat supply technique and the utilization of secondary energy. The designed structure of the device makes it possible to process and preserve the quality properties of plant-derived pomace, allowing the use of this product for a wide range of foodstuffs
Devising manufacturing techniques to control the process of zonal segregation in large steel ingots

Published: July 2021

A method of physical modeling was applied to study the effect of external actions on the processes of crystallization and the formation of the structure of ingots. A brief review of existing hypotheses about the evolution of physical, structural, and chemical heterogeneities in large steel ingots is given. The parameters of the structure and the two-phase zone have been determined, as well as the nature of the distribution of segregated materials along the cross-section of ingots, depending on the conditions of their curing. The decisive importance of convective and capillary mass transfer in the interdendritic channels of hardening ingots on the formation of a zonal heterogeneity at their cross-section has been proven.
Experimentally, when crystallizing a model environment (camphene), it has been visually confirmed that the flow of segregated materials in interdendritic channels occurs when a certain amount of impurities accumulates in them. A clear dependence of the speed of this flow on the rate of melt crystallization has been established. With an increase of the hardened part of the melt, the rate of segregated material movement (Vl) increases while the rate of crystallization (R) decreases due to worsening heat release conditions. At a certain distance from the ingot’s surface, these rates become equal, and impurities are carried to the curing border, which is the main cause of the formation of zonal segregation.
The results reported here show that the evolution of zonal segregation in ingots can be controlled using various techniques involving external influence on the hardening melt. This study has demonstrated that the adjustable intensity of heat removal from an ingot, as well as the addition of external excess pressure on the hardening melt, could be used as such tools. In the study, to obtain ingots with a minimum level of chemical heterogeneity, it would suffice to provide the following conditions for the curing of the alloy: a value of the alloy crystallization speeds at the level of Rcr ≥ 9·10–2 mm/s, or external pressure on the free surface of ingots Рext. ≥ 135 kPa.
The industrial implementation of the reported results could make it possible to improve the technology of obtaining large blacksmith ingots, provide savings in materials and energy resources, increase the yield of a suitable metal, and improve its quality
Development of a mathematical model of vibratory non-lift movement of light seeds taking into account the aerodynamic forces and moments

Published: July 2021

The modern practice of using vibratory machines when working with fine-size light-weight seeds is faced with such an undesirable phenomenon as the impact of aerodynamic forces and moments on the kinematics of vibrational movement of particles of the seed mixture fractions.
According to the results of scientific studies devoted to the solution of this problem, only mathematical models of vibrational movement are used, where the aerodynamic factor is taken into account as taking the seeds by airflow. This is typical only for cleaning modes with the rebound of seeds from the vibrating surface. Aerodynamic forces and moments are present in them only as a force of aerodynamic resistance. The action of lateral aerodynamic forces and their moments are not taken into account. Their consideration allows to extend the range of action of the aerodynamic factor on the modes of vibration cleaning (vibroseparation) without rebound (but with sliding and rolling) which are of greater interest in terms of improving the efficiency of processing fine-size seeds.
A mathematical model of seed vibration movement taking into account the action of a complete set of aerodynamic forces (dynamic resistance forces and lateral aerodynamic forces) and moments was proposed. This makes it possible to simulate non-lifting modes of vibrational movement of seeds. A system of algebraic equations that are linear with respect to the kinematic parameters of seed movement which was obtained by translating differential equations of movement into a finite-difference form was presented. The possibility of numerical solution of equations of movement by the Euler method was shown. The results of the evaluation of the model adequacy for the processes of vibration separation of tobacco seeds and false flax were presented. As shown by the results of calculations and experiments, the developed model provides an increase in the adequacy of the simulation results by 30 % in comparison with the model where the aerodynamic factor is not taken into account

Published: July 2021

The development of potential alternative binders to Portland cement is still becoming a global challenge in housing and infrastructure aspects. That is because cement and concrete become the major materials needed in building constructions. The Ordinary Portland cement can form a solid and hard mass when mixed with water with a certain ratio. This is due to the formation of ettringite and calcium silicate hydrate (CSH) phases that contribute to the strength of the hydrated products about 33–53 MPa. However, the manufacturing temperature of Portland cement can reach up to 1,500 °C in producing clinker. In order to lower the energy consumption and production cost, scientists were trying to utilize pozzolanic materials.
The research of pozzolanic materials as alkali-activated cement, such as soil cement or geopolymer cement, is also still conducted. Hence, a better understanding of pozzolanic reaction and its hydration products is needed. In this work, the hydration products of low-energy binders composed of Ca(OH)2-SiO2 and Ca(OH)2-metakaolin-gypsum mixtures were studied.
The hydrated products of 41 wt. % Ca(OH)2 – 41 wt. % metakaolin – 18 wt. % gypsum mixtures followed by water immersion curing at 50 °C for 28 days undergone a pozzolanic reaction. XRD characterization showed that the hydrated product is mainly composed of ettringite (60.0 %) and crystalline-CSH (23.4 %). The diffractograms obtained have shown a specific hump indicating the presence of amorphous phases besides the crystalline. To confirm the presence of the non-crystalline or amorphous phases of the hydrated products, a polarizing optical microscope (OM) using a crossed Nicols method was used. The characterization of the phases is the novelty of the present research. The ettringite, crystalline CSH and the amorphous phases act as a strong binder that consequently contribute to its average maximum compressive strength of 22.17 MPa.
Constructing a model for the automated operative planning of local operations at railroad technical stations

Published: July 2021

This paper has investigated the technology of forwarding local wagons at railroad technical stations and established the need to improve it given the extra downtime of local wagons. The main issue relates to the considerable combinatorial complexity of the tasks of operational planning. Another problem is that as part of the conventional approach, planning a station operation and planning a local operation at it is considered separately. Another planning issue is the lack of high-quality models for the preparation of initial data, in particular, data on the duration of technological operations, such as, for example, shunting operations involving local wagons forwarding. To resolve these issues, a new approach has been proposed, under which the tasks of operative planning of a technical station’s operation and its subsystem of local operations are tackled simultaneously, based on a single model. To this end, a mathematical model of vector combinatoric optimization has been built, which uses the criteria of total operating costs and wagon-hours spent at a station when forwarding local wagon flows, in the form of separate objective functions. Within this model, a predictive model was constructed in the form of a fuzzy inference system. This model is designed to determine the duration of shunting half-runs when executing the spotting/picking operations for delivering local wagons to enterprises’ goods sheds. The model provides for the accuracy level that would suffice at planning, in contrast to classical methods. A procedure has been devised for optimizing the planning model, which employs the modern genetic algorithm of vector optimization NSGA-III. This procedure is implemented in the form of software that makes it possible to build a rational operative plan for the operation of a technical station, including a subsystem of local operations, in graphic form, thereby reducing the operating costs by 5 % and the duration of maintenance of a local wagon by 8 %. The resulting effect could reduce the turnover time of a freight car in general on the railroad network, speed up the delivery of goods, and reduce the cost of transportation

Authors: Gorbenko Ivan , Zamula Oleksandr
Published: July 2021

Information and communication systems (ICSs) must comply with increasingly stringent requirements to ensure the reliability and speed of information transmission, noise immunity, information security. This paper reports the methods to synthesize discrete complex cryptographic signals, underlying the construction of which are random (pseudo-random) processes; the methods for synthesizing characteristic discrete complex signals whose construction is based on using the nature of the multiplicative group of a finite field; the results of studying the properties of the specified signal systems. It is shown that the methods built provide a higher synthesis performance than known methods and make it possible to algorithmize the synthesis processes for the construction of software and hardware devices to form such signals. The win in the time when synthesizing nonlinear signals in finite fields using the devised method is, compared to the known method, for the period of 9,972 elements is 1,039.6 times. The proposed method for synthesizing the entire system of such signals, based on decimation operation, outperforms the known method of difference sets in performance. Thus, for a signal period of 2,380 elements, the win in time exceeds 28 times. It has also been shown that the application of such systems of complex signals could improve the efficiency indicators of modern ICSs. Thus, the imitation resistance of the system, when using complex discrete cryptographic signals with a signal period of 1,023 elements, is four orders of magnitude higher than when applying the linear signal classes (for example, M-sequences). For a signal period of 1,023 elements, the win (in terms of structural secrecy) when using the signal systems reported in this work exceeds 300 times at a period of 8,192, compared to the signals of the linear form (M-sequences)

This paper reports a study into the use of germinated mungbean as a promising raw material influencing the structure-forming indicators of meat systems during the production of meat-vegetable sausages. The content of iodine in the germinated mungbean and its anatomical parts has been examined using solutions of potassium iodide. A change in the phytic acid content and size of phytin globoloids has been established in mungbean malt depending on germination conditions. The influence of flour from germinated mungbean on the moisture-binding, moisture-retaining, fat-retaining abilities, as well as on the pH of meat systems based on veal meat, pork, chicken has been investigated.
The reported set of studies is important as the defined patterns could make it possible to devise technologies for meat-vegetable sausages, to expand the range of enriched meat products.
The result of this study has established that the degree of biotransformation of iodine into beans is influenced by the protein content in the native beans. Almost 90...95 % of iodine is accumulated in the cotyledons of beans in the protein fraction, 5...10 % ‒ in sprouts and roots. The rational range of potassium iodide concentrations in the germination solution is 76.5 g per 1,000 cm3, over 48 hours. Prolonging the germination time leads to microbiological damage to the bean mass.
The germination process affects the reduction of phytic acid content, which is confirmed by a decrease in the diameter of phytin globoloids.
It is rational to use in meat systems based on pork meat and veal meat 10 % of the developed flour by reducing meat raw materials. With this ratio of formulation ingredients, the maximum increase in the moisture-binding, moisture-retaining, and fat-retaining capacities of these meat systems is achieved. In the meat systems based on chicken meat, it is possible to increase a replacement part of up to 15 %.
The reported set of studies is useful and important because it could form the basis for devising the technologies of meat-vegetable sausages to meet the needs of different segments of consumers

Published: July 2021

A procedure for analyzing the effectiveness of using fuel and energy resources (FER) in sugar production, based on the developed idealized circuit of the thermal-technological complex (TTC) as the base for comparison was presented. This procedure makes it possible to quantify the level of perfection of existing and proposed thermal circuits, as well as the impact of measures for enhancing energy efficiency on their perfection.
By idealizing technological and energy processes, a hypothetical TTC was synthesized, for which the minimum possible energy and entropy characteristics are determined. Under these conditions, the minimum possible heat consumption for the implementation of technological processes according to the classical heat technology circuit was calculated – 118.40 MJ/t; a "minimum" total increase in entropy from irreversible processes of the HTC – 314.68 kJ/(t·K); a minimum complex magnitude of specific consumption of conventional fuel – 0.8 % to m. b.
The determined characteristics are absolute criteria for the efficiency of sugar production systems, since it is impossible to reach lower values under existing technology, quality of raw materials and other conditions. The content of the criteria of energy efficiency of TTC was stated and the system of coefficients was proposed: coefficient of total energy efficiency of the TTC, coefficient of energy efficiency of the system of heat supply of the technological processes and coefficients of energy efficiency of internal and external structures of the TTC. The proposed criteria provide an objective and thermodynamically correct characteristic of the TTC of different structures.
The presented results of analysis of various measures for increasing the energy efficiency of sugar production show that only a gradual comprehensive reconstruction of an enterprise makes it possible to consistently reduce the FER consumption for technological needs, approaching the boundary values.

The study of the components of the balance of biogenic elements in anthropogenic ecosystems has been carried out and the mechanism for calculating the balance of biogenic elements has been determined. The necessity of improving the existing methodology is proved, which consists in preliminary modeling of the catchment area using geoinformation methods. On the example of the mouth of the river, a drainage area was modeled in Oril, during which the boundaries and total catchment area were determined, which is 39.7 thousand hectares. Experimental studies have determined the area of land according to their types of nature use (industrial, residential, forestry and agricultural, etc.). It has been established that only 15% of the investigated lands have agricultural use, however, it is this type of nature management that most contributes to biogenic pollution of this ecosystem. According to the results of calculations, it is determined that up to 10 thousand tons of nitrogen and phosphorus, respectively, are accumulated in the soil due to the excess use of mineral fertilizers. The results obtained indicate the feasibility and practical attractiveness of the proposed approach for calculating the balance of nutrients. Improvements include the application of digital elevation model and normalized vegetation index geodata obtained using ArcGIS Desktop software. It is shown that the technique used will allow obtaining the results of the adjusted volumes of nitrogen and phosphorus accumulation in soils and indicating the sources of their input.
Thus, there are grounds for improving the methodology for calculating the balance of nutrients through the use of information technology. The geoecological approach will intensify the monitoring of nutrients, which will help to regulate the pressure on the ecosystem.

Published: July 2021

An important place in human nutrition is occupied by omega-3, omega-6 and omega-9 fatty acids (FA). They have different effects on the human body and play a significant role in the appearance and the course of some diseases (for example, cardiovascular system, gastrointestinal tract, cancer, obesity, etc.).

The aim. To study the qualitative composition and the quantitative content of fatty acids in Common Lilac (Syringa vulgaris) flowers of “Madame Lemoine” variety.

Materials and methods. The fatty acid composition was studied by gas chromatography based on the formation of methyl esters of fatty acids and their subsequent determination.

Results and discussion. The presence and the quantitative content of 15 fatty acids have been determined. Among them, 13 FA have been identified, namely 6 saturated fatty acids and 7 unsaturated fatty acids. The total amount of saturated fatty acids (54.65 %) significantly predominates over unsaturated fatty acids (34.81 %). Palmitic acid dominates among saturated FA (39.83 %). Linoleic acid has the highest percent among unsaturated FA (13.75 %).

Conclusions. For the first time the composition of fatty acids in Common Lilac flowers of “Madame Lemoine” variety has been studied. The raw material accumulates saturated fatty acids in a significant number. Palmitic acid (C 16 : 0) – 39.83 % and linoleic acid (C 18 : 2) – 13.75 % are the dominant acids
Legal regulation of the universal European election process
Authors: Son Sofiia
Published: July 2021

The study is devoted to the analysis of the main normative legal acts, regulating the holding of elections within the European Union, linked to the evolution of Ukrainian Constitutionalism and the integration of Ukrainian law into the European legal space. It has been proved, that the correct choice of an electoral system creates a suitable environment for the citizens to exercise one of the fundamental democratic rights, namely to elect their authorized representative who in their turn represent their interests.
The article states that despite the growing role of the European Parliament, the election procedure has been only partially coordinated due to the lack of the universal election procedure for all EU members. At present some fundamental principles, regulating this procedure, are stipulated by the 1976 Election Law, however a lot of aspects are regulated by the national legal systems. The lack of universal election law for all EU members potentially deprives European elections of a real European dimension. The recent years have witnessed several attempts to reform the EU election system. However not all of them have led to the adoption of relative Directives. In particular, there are disputes regarding the transnational constituency.  The supporters believe it to be the step in the right direction, while the opponents express fears that it will increase the distance between the public and its elected representatives. The author points out that the outcomes of the spring 2019 European Parliamentary elections have common features with the outcomes of Parliamentary and local elections in Ukraine. Problems, related to the European Parliament elections in 2019 and existing in Ukraine, have been identified, such as restrictions for the exercise of voting rights by persons with disabilities due to various reasons, the use of digital technologies and related cybersecurity issues in the election process, protection of personal data and so on

The analysis of the researched scientific problems on counteraction to crimes, committed by organized groups and criminal organizations, which are formed on an ethnic basis, now necessitates further research of ethnic crime in Ukraine and the world in general. Formation by the Ukrainian state of a multi-vector mechanism of counteraction to organized groups and criminal organizations, formed on an ethnic basis, is impossible without understanding the essence of this problem, relevant legal concepts and classification and identification of features of organized ethnic crime that are important for law enforcement and the state. The main effective factor in such activities is to guarantee the security of citizens and the integrity of the state from criminal encroachments of organized groups and criminal organizations that are formed on an ethnic basis. Thus, for the effective interaction of law enforcement agencies in combating crimes, committed by organized groups and criminal organizations that are formed on an ethnic basis, a sound concept of such cooperation is needed, which is currently lacking. Accordingly, in the long run, such a concept needs to be adopted immediately, which will start streamlining law enforcement relations on the exchange and realization of information concerning the activities of both domestic criminal groups and organized criminal groups of foreign nationals or those formed on ethnic grounds. Theoretical principles of law enforcement interaction in combating crimes, committed by organized groups and criminal organizations, which are formed on an ethnic basis by generalizing, analyzing and systematizing the concept of interaction, its forms, methods and types, are analyzed. An author's definition of the concept of interaction among police during counteraction to crimes, committed by organized groups and criminal organizations, formed on ethnic basi, is given

The article is devoted to the aspects of the implementation of the principles and the specifics of the appointment of forensic examination in civil proceedings. The system of normative legal acts on forensic examination in civil proceedings has been investigated. The relationship between the concepts of "expertise" and "forensic examination" have been determined and analyzed. The characteristic features of forensic examination have been studied: first, forensic examination is determined by a specific procedural form; secondly, it can be carried out on the basis of a court order; thirdly, forensic examination is carried out by a forensic expert; fourthly, a correctly drawn up expert opinion is a means of proof in civil proceedings; fifth, the results of the forensic examination are used by the court. Highlighted and analyzed are the principles of forensic examination in civil proceedings, provided for by Art. 3 of the Law of Ukraine "On Forensic Expertise", namely the legality, independence, objectivity and completeness of the study. Separately, the set of conditions for which, in accordance with Art. 103 of the Civil Procedure Code of Ukraine, the court appoints an examination of the case: firstly, to establish the circumstances that may be significant for the case, for the sake of which special knowledge is required in a field other than law, without which it is impossible to establish the relevant circumstances; secondly, in the case when the parties or the party did not present the expert's opinion on a specific issue or the expert's opinion raises doubts about its correctness. A list of specific actions that the court at the stage of deciding on the appointment of a forensic examination has the right to implement in accordance with the Resolution of the Plenum of the Supreme Court of Ukraine dated May 30, 1997 No. 8 "On forensic examination in criminal and civil cases" is provided. The aspects of the appointment and conduct of forensic examination in civil proceedings are analyzed. The facts are highlighted that should be taken into account when deciding on the advisability of appointing an examination in a civil case

The object of research of this work is the methods of deep learning for source code vulnerability detection. One of the most problematic areas is the use of only one approach in the code analysis process: the approach based on the AST (abstract syntax tree) or the approach based on the program dependence graph (PDG).
In this paper, a comparative analysis of two approaches for source code vulnerability detection was conducted: approaches based on AST and approaches based on the PDG.
In this paper, various topologies of neural networks were analyzed. They are used in approaches based on the AST and PDG. As the result of the comparison, the advantages and disadvantages of each approach were determined, and the results were summarized in the corresponding comparison tables. As a result of the analysis, it was determined that the use of BLSTM (Bidirectional Long Short Term Memory) and BGRU (Bidirectional Gated Linear Unit) gives the best result in terms of problems of source code vulnerability detection. As the analysis showed, the most effective approach for source code vulnerability detection systems is a method that uses an intermediate representation of the code, which allows getting a language-independent tool.
Also, in this work, our own algorithm for the source code analysis system is proposed, which is able to perform the following operations: predict the source code vulnerability, classify the source code vulnerability, and generate a corresponding patch for the found vulnerability. A detailed analysis of the proposed system’s unresolved issues is provided, which is planned to investigate in future researches. The proposed system could help speed up the software development process as well as reduce the number of software code vulnerabilities. Software developers, as well as specialists in the field of cybersecurity, can be stakeholders of the proposed system.

The object of research is the military radio communication system. One of the most problematic areas in the management of military radio resources is the interference of military radio systems and facilities. A number of works have been devoted to the research of ways to increase the noise immunity of military radio communication systems and facilities. However, the known works contain some results of research by scientists aimed at increasing the noise immunity of military radio systems and facilities and do not have a comprehensive approach. In this article, the problem of developing a method of structural-parametric synthesis of the noise protection subsystem of special purpose radio communication systems is solved.
The scientific problem is solved by formalizing the problem of structural-parametric synthesis of the noise protection subsystem of military radio communication systems, starting with its mathematical description and synthesis of the quantitative and qualitative structure of the noise protection subsystem. In the course of the research, the authors used the main provisions of the queuing theory, the theory of automation, the theory of complex technical systems and general scientific methods of cognition, namely analysis and synthesis. The novelty of this technique is the synthesis of the structure of the military radio system and the parameters of the radio system in the context of electronic conflict. This technique is multi-criteria, in which the parameters are different in importance. The basis of this technique is the principle of nonlinear scheme of A. Voronin compromises. This technique allows to:
– to synthesize the structure of the radio communication system in the conditions of electronic conflict;
– to determine the optimal number of radio communication devices to ensure management tasks in the conditions of electronic conflict;
– to substantiate a set of mechanisms to increase the noise immunity of the noise protection subsystem in the conditions of electronic conflict.
The results of the research should be used at the stage of planning and operational management of the structure and parameters of military radio communication systems.
