Authors: Sulista Cici , Latif Abdul
Published: August 2020

The object of this study are two poems from different authors, namely the poem “I Love You In Silence” by Jalaluddin Rumi with the poem “Great Love” by Kahlil Gibran. This study aims to compare the style of language of the two poems. The method used by the authours in this study is the comparison method. The results showed that there where three similarities and two differences found in the two poems. First, there are there are similarities in the style of language. Secondly, there are similiraties in the style of language based on the structure of sentences, both poems use the name style of repetition language, and not only that the third equation is found in the direct or indirect meaning of meaning because both poems also use the style of personification. As for the difference between the two poems there are two differences. First, it lies in the phrase used in the repetitive language style, if in the poem Rumi uses the phrase ‘I Chose’ while Gibran uses the phrase ‘when’. Second, there is difference in the function of the repetitive language style used, when Rumi uses the repetitive language style to confirm the action taken against the person in love, in contrast to Gibran who uses the repetitive language style to explain the true nature of love.

The Socio-Economic Impact of Syrian Refugees on Labor in Jordan: Case Study on Local Communities in Mafraq Governorate
Authors: Alsoudi Abdelmahdi
Published: August 2020

Jordan is heavily affected by the influx of over 1.4 million Syrians among them 655,000 registered refugees. Today, the country has been struggling to provide housing, water, education, healthcare and jobs to its increased population and this huge number of Syrian refugees. When Syrians first arrived to Jordan they received assistance and sympathy from the host communities but once it became clear that they are here to stay and started to compete with local population for food, housing, jobs and services things started to change. Host communities in Mafraq and elsewhere in the country became weary of refugees, as the two groups have to compete over such scarce socio-economic resources and would rather see Syrians go back to their country. The study recommends more international aid to Jordan to enable the government to provide food, jobs and services to its population and refugees. The government should provide economic aid for the local population in Mafraq to help them cope with the refugees’ crisis.
Were the Early Firaq Extremists? Rethinking the History of Muslim Disagreement(s
Authors: Abd Rahman Amilah binti Awang , Abdul Rahim Adibah binti
Published: August 2020

Many writers have associated contemporary manifestations of extremism with early Islamic sects, which is argued against in this article. The study employs critical analysis of available sources and argues for additional scrutiny. Our position is supported by detailed scrutiny of early sectarian contributions to the development of Islamic thought. We discovered remarkable limitations in the tracing of the roots to the early firaq (sects) due to a strong reliance on secondary sources muddled in the complexities of dogmatic polemics. Nonetheless, relevant historiography improved our view of what actually happened when nascent Muslims confronted humorless political and social problems. Rather than producing extremist deviants, early Islamic thought was exceedingly dynamic and governed by a pressing need to defend sound Islamic principles. Early Muslims sought answers to perennial issues and did much to stimulate subsequent Muslim philosophy and thought. Indeed, any negative understanding of this early legacy undermines the dignity of that era and people.
Da‘wah Activities of the Pakistani Barelwis: Case of the Da‘wat-i-Islami
Authors: Ahmad Mujeeb
Published: August 2020

The purpose of this study is to highlight the da‘wah approaches and methodology of the Da‘wat-i-Islāmī (DI) and contribution along with a survey of the da‘wah activities of the Barelwis, based on primary sources. DI uses the Barelwi faith as its religious mark. Barelwis are representatives of the ‘popular’ and ‘Ṣūfī-oriented’ Islam. The driving force behind this facet of Islam is ‘to love Prophet Muḥammad (SAW) and follow his Sunnah’. This is the focal point of all da‘wah activities of the Barelwis. DI started its work in Karachi in 1981. It aims at promoting and deepening love for the Prophet Muḥammad (SAW). Its next aim is to establish a society similar to the early Muslim community of Madīnah through peaceful preaching. It expanded gradually all over Pakistan and then became so conspicuous, that nowadays it is functional in more than 180 countries and thus has turned into a global tablīghī movement. It has its own edifying literature. The most important of which is Faīḍān-i-Sunnat. In this work, the Sunnah of the Prophet regarding daily affairs of life has been narrated. For the religious training, inter alia, it also holds weekly meetings in different cities and towns of Pakistan and even in some European cities as well. The members of the DI have to show their commitment to the Islamic way of life as reflected in the Faīḍān-i-Sunnat. Besides religious sector, it is also working in social and educational fields. Although it is supported with reference to its aims to build character in its individual members, it nevertheless attracts diverse criticism about some of its practices.
Islam and Myths about Family Planing: The Impact of Greenstar Media Advertisement Campaign on the Mindset of the Rural Dwellers of Pakistan
Authors: Waheed Saima , Saleem Noshina , Riaz Ayesha , Far Bukhari Seemab
Published: August 2020

Religious guidance in Islam is derived primarily from the Holy Qur’ān and Sunnah. For cases not discussed in the Holy Qur’ān, Muslims refer to ijtihad and ijma, that is, they strive to find solutions for the existing problems by reinterpreting Islamic decrees while utilizing the ultimate superintendent sources (Holy Qur’ān and Sunnah) and seek consensus. The study aims to investigate the effects of Greenstar media advertisement campaign on the mindset of the rural dwellers of Pakistan through selective exposure technique. Greenstar marketing tends to educate the rural populace about population control and guides them about different birth control methods, such as contraceptive pills. The researchers carried out a survey with a sample of 200 respondents, out of which 100 were male and 100 were female. Data was collected by providing two questionnaires to take sample from different age groups developed on a five point Likert scale. The results of the study highlighted that regardless of exposure to Greenstar media advertisement, rural men still showed a rigid attitude towards using these products (p value = 0.000). On the other hand, rural women considered local midwives more knowledgeable and expert about the matter at hand (p value = 0.002) and were reluctant towards using Greenstar products that were advertised on the mainstream media due to the pressure of their husbands (p value = 0.000).

Published: August 2020

Sound health is considered a prerequisite for performing any action, whether it is participation in sports or performing any other activity of life. From the perspective of Islam, health and fitness are imperative for the appropriate performance of various religious obligations. Sports and other physical activities are considered very effective means to achieve good health. In this paper, the researchers analyzed diverse Islamic standards and rules with reference to participation in games. Moreover, researchers also analyzed the preservation and maintenance of health in the light of the teachings of Islam. After a brief discussion, it was concluded that the Islamic approach is very clear and Islam endorses the upkeep and maintenance of health, fitness and physical power. It was also concluded that sports and other physical activities of today are variations of such activities performed in the past. The study also claims that Islam promotes involvement in leisure sports and other physical activities carried out to strengthen the body and to retain fitness, while observing Islamic teachings, formulated rules and regulations. It can be inferred that the Holy Prophet (SAW) not only took part in different games but also convinced and encouraged his disciples to take part in sporting activities.

Authors: Stanislavovich Tatiana , KUZMINA T. I.
Published: August 2020

Abstract. Intraovarian vitrification of oocytes of farm animals today is a very promising direction. The composition of cryoprotective solutions requires further improvement. Vitrification of ovarian fragments (FО) allows tо save primordial follicles, a structure that is more stable, due to the lack of follicular fluid, to destructive processes provoked by ultra-low temperatures.The high reproductive potential of pigs is due to their physiological characteristics of growth and development. Silicon is a minor trace element in its content; it is increasingly used in pharmacology, veterinary medicine, and clinical practice. Nitrogen silicon dimethylglycerolate (SDMGC) are antimicrobial, wound healing and anti-inflammatory in nature. The presence of a compact cumulus surrounding the oocyte is one of the important indicators of the reliability of the female gamete for extrafollicular maturation. Purpose of this study: to was to evaluate the effect of introducing 0.2 % silicon dimethylglycerolate into cryoprotective solutions during intraovarian vitrification and the medium for maturation of devitrified oocyte-cumulus complexes of pigs on the morphology of cumulus cells and the state of nuclear material. Ovarian fragments of pigs (15mmx 20mm) to vitrification are exposed prior for 25 minutes and 15 minutes direct in cryoprotective solutions of the following composition: CPA 1 – 7.5 % ethylene glycol (EG), 7.5 % dimethyl sulfoxide (DMSO), 65 % phosphate-buffered saline (PBS), 20 % fetal bovine serum (PBS); CPA 2 – 20 % EG, 20 % DMSO, 60 % FSB, 0.5 mol / L sucrose. The experimental group was treated for 10 minutes in a solution of phosphate-saline buffer with 0.2 % SDMGC. Hoechst 33258 was used to evaluate chromatin status, samples were analyzed using a ZEISS Axio Imager Imager A 2 m microscope.The result. Incubation of ovarian fragments of pigs in a solution containing 0.2 % SDMGC before vitrification, as well as the introduction of 0.2 % SDMGC in the composition of oocyte maturation media, had a positive effect on the morphology of cumulus cells (degree of expansion) after the thawing procedure. The proportion of compact cumulus devitrified cells pretreated with 0.2 % SDMGC increased compared with the control group (64 % vs 56 %, P < 0.05 (χ2-test). The level of oocytes with cumulus is in a high degree of expansion after 44 hours of cultivation with 0.2 % SDMGC in the experimental group was 75 % vs 54 % in the control group, P < 0.05 (χ2-test). The use of SDMGC in the cultivation of devitrified oocyte-cumulus complexes of pigs for 44 hours increased the proportion of matured oocytes from 41 % in the control group to 64 % in the experimental group P < 0.05 (χ2-test). The scientific novelty: the stages of the technology of intraovarian vitrification of porcine oocytes by means of preventive incubation of ovarian fragments in a solution of 0.2 % SDMGC and its introduction into the medium for culturing oocyte-cumulus complexes were modernized.

Authors: Abdullaev Ramzi
Published: August 2020

Abstract. The purpose of this study is to determine the role of investments in the development of agricultural infrastructure, including in the development of new approaches to the formation and use of investments as a factor in increasing the economic efficiency of the agricultural economy. The research method is comparative and analytical analysis, calculations using the “eviews” software package and a systematic approach. To determine the possibilities of creating the volume of investment products directed to fixed capital in agriculture, it is possible to construct a mathematical function of investment in agriculture, both in theoretical and practical terms. For example, in the form of the dependence of investments in fixed assets in agriculture on the volume of products produced, depending on the rate of return in agriculture, interest rates, etc. As a result of the study, the main directions of investment attempts to increase economic efficiency in agricultural industry. It was concluded that investments in agriculture in the Republic of Azerbaijan increased by 393.9 million manats in 2010 compared to 2003, and by 727 million manats in 2018. However, this growth is not at the desired level. In short-term and closed economic conditions, the multiplicative efficiency can be higher. The scientific novelty of the study consists in clarifying the essence and role of investment as an economic category based on its definition in both a narrow and a broad sense, as well as in identifying trends and patterns in the formation and use of investments in the agricultural economy.

Estudos atuais descrevem que em 2025 um total de 322 milhões de indivíduos serão diagnosticados com disfunção erétil. Visto ainda que a abordagem medicamentosa com inibidores das fosfodiesterases se considere eficaz, de fato, deveria permitir a reversão das alterações patológicas encontradas na origem desta disfunção, visando uma melhora na atividade sexual espontânea. Desta forma terapia extracorpórea por ondas de choque tem vindo a desenvolver-se com o intuito de restaurar as alterações e talvez curar esta patologia de modo. O objetivo desse estudo foi avaliar e descrever a utilização da terapia extracorpórea por ondas no tratamento dos pacientes com disfunção erétil\ impotência sexual, seja ela associada com outras abordagens ou isolada. O presente estudo trata-se de um estudo de natureza bibliográfica específica e exploratória, descritivo com abordagem qualitativa, realizada nos meses de abril e junho do corrente de 2020 nas bases de dados SCIELO, LILACS e Google Acadêmico. Foram empregues os descritores: Disfunção Erétil; Tratamento por Ondas de Choque Extracorpóreas; Disfunções Sexuais Fisiológicas os mesmos foram combinados utilizando-se o operador booleano AND, sem restrição linguística na janela de tempo de 2015 a 2020. Os escritos foram examinados detalhadamente na integra para que pudéssemos obter conhecimentos e referencias consistente, no que diz respeito ao tema. Para realização do estudo identificou-se 78 artigos e após avaliação e leitura e aplicação dos critérios de inclusão e exclusão quatro artigos foram compatíveis com o estudo. Estudos clínicos demonstram que terapia extracorpórea por ondas de choque trás melhorias na função hemodinâmica peniana bem como reversão de certas alterações patológicas. Visando um melhor atendimento, os protocolos da terapia extracorpórea por ondas de choque foram criados para utilização peniana que consiste de 2 sessões semanais por 3 semanas, 3 semanas de descanso seguido de mais 2 sessões semanais por mais 3 semanas. Cada sessão podendo durar em média 20 minutos e se utiliza um aparelho especificamente criado para utilização na região do pênis. Estudos clínicos iniciais demonstram uma melhora significativa de cerca de 75% dos pacientes submetidos quando comparados com um grupo controle, não sendo demonstrado ocorrência de nenhum efeito adverso significativo. Conclui-se que a terapia por ondas de choque tem-se revelado uma técnica promissora no tratamento das disfunções eréteis, podendo levar à reversão de certos mecanismos envolvidos na génese desta patologia, todavia há ainda necessidade de estudos que ajudem a avaliar mais profunda e globalmente os resultados, métodos e grupos que mais beneficiam da aplicação deste tratamento e estudos quem ampliem o entendimento da área.

The efficiency of air cooling at the inlet of gas turbine engines by exhaust heat conversion chiller, which transforms the GTE exhaust gases heat into cold, under variable climatic operating conditions, has been investigated. Considered is the use of a combined absorption-ejector exhaust heat conversion chiller with a step-by-step principle of air cooling at the gas turbine engines inlet: preliminary down to 15°C – by an absorption lithium-bromide chiller (ACh), which is used as a high-temperature air cooling stage, and further cooling down to 10°C – by a refrigerant ejector chiller (ECh) as a low-temperature cooling stage. Reserves have been identified for reducing the design (installed) refrigeration capacity of chillers by accumulating excess cold at reduced current heat loads with its use at increased heat loads. In this case, the design (installed) refrigeration capacity of chillers was determined by two methods: the first – based on the close to the maximum reduction in annual fuel consumption, the second – according to the maximum rate of increase in the reduction in annual fuel consumption. A scheme of the air cooling system at the gas turbine engines inlet using the refrigeration capacity reserve of the ACh, which provides preliminary cooling of the ambient air at the gas turbine engines inlet, in the booster stage, using the ACh accumulated excess refrigeration capacity has been proposed. The ACh excess refrigerating capacity, which is formed at decreased heat loads on the air coolers at the gas turbine engines inlet, is accumulated in the cold accumulator and is used at increased heat loads. The simulation results show the advisability of using the air cooling system at the gas turbine engine inlet with using the ACh accumulated excess refrigeration capacity, which allows reducing the ACh design (installed) refrigeration capacity by approximately 40%.

The subject of the study is methods for determining vessel volume with complex shapes. The aim of the study is a development and scientifically substantiate of a method for fast measurement of an internal cavity volume of a vessel having a complex geometric shape in a gaseous medium based on supercritical outflow. The task of the study is the development of a method for calculating the volumes of the gas path components for the previously proposed generator of gas mixtures, which based on the supercritical outflow from intermediate tanks with constant volume, and confirmation of the proposed method capabilities using a simulation of the volume measurement process by the same method. The following results were obtained. It is proposed the method for fast measurement of vessel volume with complex shape based on supercritical flow through nozzles with the predetermined flow rate and dynamic measured pressure. The range of measurement time is substantiated for which, on the one hand, the conditions for suppressing transient processes in the measured vessels after the beginning of the supercritical outflow of the process gas are satisfied, and on the other hand, the conditions for adiabatic outflow are provided. According to the simulation of measuring the volume of a complex-shaped vessel using the proposed method, the accuracy of determining the volume of the vessel was 0.0625% in relation to the CAD system data. To use the proposed method in practice, the measuring equipment should include a reference vessel, and the measurements themselves should be carried out in two stages, using the same gas for filling in both cases. In this case, at the first stage, according to the results of the control measurement when it expires from the reference vessel, the value of the flow coefficient is specified, and at the second stage, when it expires from the measured vessel, the required target volume is determined. The process of direct volume measurement, in this case, lasts up to 1 second, the accuracy of volume determination is expected to be 0.1%.

The subject matter of the article is the processes of virtual localization of near shape parts during adaptive machining. The aim is to develop an effective method for finding the starting location of a CAD model of a part with virtual localization inside a point cloud obtained by laser scanning of a workpiece. The task is to formalize the procedure for starting positioning of the part model as the first stage of the virtual localization process. The second stage for final localization proposed to use iterative algorithms with the objective function which is sensitive to the intersection of the surface parts and the workpiece. In solving the problem the starting position used tools available in today's CAD packages and 3D scanning tools. The methods used are the methods of matrix algebra, in particular, the methods for finding the main central moments of inertia of three-dimensional objects based on the tensor of inertia. The following results were obtained. When calculating the inertia tensor components is proposed to use three-dimensional scanning data of workpiece and geometrical data of part obtained from the CAD system. The result is an algorithm starting location of CAD model in the virtual localization, which in the case of blanks with oversize close to uniform can provide enough current location parts for adaptive machining tasks. It is shown that to minimize computational errors and to ensure satisfactory accuracy of localization proposed algorithm can require several iterations of the shift vector search model. Conclusions. The scientific novelty of the results obtained is as follows: in contrast to the previously used approaches, when solving the problem of virtual localization for the starting position, using the condition of coincidence of the centers of the weight of thin shells coinciding with the surfaces of the workpiece and the part, it was proposed to additionally ensure the alignment of the main central axes of inertia of these shells, which, in the case of near shape blanks, provides a positioning accuracy that may not require additional iterative procedures.

In recent years, the security and defense sector of Ukraine has been undergoing reforms aimed at gaining the country's membership in the NATO North Atlantic Treaty Organization. One of the many aspects of these reforms is the introduction of some specific standards, in particular, the AQAP 2000 series standards in the quality management systems of military equipment enterprises. In the case of implementation of several international standards at the enterprise, there is a need to create integrated quality management systems. The article presents options for implementing two or more standards in the QMS of the enterprise, analyzes their disadvantages and advantages. The main requirements of the AQAP 2110 standard, which should be integrated with the requirements of the ISO 9001 standard in the context of the PDCA cycle ("Plan-Do-Check-Act"), are considered. The stages of the implementation of integrated QMS are described. The scheme of deliveries of products to the customer in which there is a certification of the quality management system of the manufacturer (supplier) by the external body on conformity assessment, control over the quality of production by military representation, and the government quality assurance GQA has resulted. Government quality assurance GQA means that the authorized national body carries out the process of assessing the conformity of the quality management system of the manufacturer (supplier) to the requirements of ISO 9001 and NATO standards AQAP 2000, which allows the customer to gain confidence in the quality of defense products. A special requirement is to draw up a Quality Plan, which defines the activities, processes, resources, responsibilities of the manufacturer, etc., to convince the customer and the GQA representative that the company can manufacture and supply products of appropriate quality and on time, because in case of defective products or failure to deliver is lost time for a replacement or waiting, and this is a constant risk to the country's combat readiness. Requirements for the content and design of the Quality Plan are given in the standard AQAP 2105. In addition to the above, the following specific requirements of AQAP 2110 are analyzed as the operation of the metrological support system at the enterprise according to DSTU ISO 10012, product configuration management with software according to ACMP 2100, risk management, etc.

The article touches upon the issues of the operating process in the elements of the external gear pump modeling. The external gear pump is the part of the gas turbine engine and pumps a low-viscosity fluid – kerosene. The article shows that sleeve bearings in such pumps continue to operate at boundary friction modes while rotation speed is increased. It also shows that the end and radial clearances are variable, and the drain system is not optimal which prevents the modeling of the system by classic approach. The main elements of the pumping unit of the external gear pump are described in the article. A simplified geometric model, which forms the basis for the analysis of the pump operation, is given as well. The problems arising during the design stage, fine-tuning, and operation of external gear fuel pumps are briefly described. A preliminary analysis of the design methods showed that several parameters of the working process are not studied well enough to provide the basis for optimal construction design and its qualitative assessment within the design stage. The description of gears operation, the system of end clamping, end, and radial plain bearings is given. The analysis of pressure distribution models is given. The analysis takes into account pressure distribution from linear distribution in the delivery chamber to the pressure drop on one tooth. Distributions from different calculation methods and literature sources are compared as well. The features of bearing loading and the conditions of their operation and lubrication are described.

SLM technology is an innovative production of products of complex geometric shapes through layer-by-layer material building-up based on a computer-based CAD model using special 3D printers. With the help of SLM technology, they create precise metal products for work as part of components and assemblies for critical purposes (for example, aerospace). SLM successfully replaces traditional manufacturing methods, since products built using SLM technology often surpass the properties of products made using traditional technologies.This technology has several advantages for the application and manufacture of aerospace products: the possible production of thin-walled parts, simplifying their production, by reducing the number of technological transitions, using computer programs and automation tools to optimize the product design, which opens up the possibility of reducing the weight of aircraft structural elements apparatuses.One of the opportunities that SLM technology allows to realize is the replacement of solid metal elements with openwork structures, ensuring a sufficient level of mechanical properties. The use of openwork designs and topological optimization can make it possible to lighten a part up to 50 %. However, it is important to ensure the necessary level of mechanical properties due to the reasonable design of elements: mesh thickness, cell size, and shape, etc. Besides, in aircraft and rocket science, often additive technologies are used to create products with internal channels of thin-walled products with inclined surfaces. Therefore, it is important to ensure the quality of thin-walled surfaces with different angles of inclination.Printing was carried out on a 3-D Alfa-150 printer manufactured by ALT Ukraine LLC. As part of the experiment, samples were made in the form of a cube with the internal structure of the honeycomb and a solid cube with equal dimensions in different modes. The second group of samples in the form of plates with different angles of inclination relative to the Z-axis (0°, 30°, 45°).When practicing printing modes with internal thin structures, it was found that under adverse conditions, fusion conditions were created, the metal fell through on a layer of powder, overhanging elements formed, and the lower surface with high roughness. Under favorable conditions, the lower surface is smooth, the layers are clearly defined, correspond to the given geometry of the model. An experiment was also performed to test the printing modes of flat samples with different angles of inclination. It has been established that different modes are optimal for different tilt angles. Thus, it was found that SLM technology allows you to create thin-section elements with maximum accuracy, and to produce parts with a unique geometric structure. According to the developed process parameters, parts of complex shape for operation in aerospace engineering can be created.

There is described the work on the project, carried out at the enterprise Element JSC for the creation of aircraft gas turbine engine simulator stands, for the maintenance and testing of some digital regulators for helicopter and aircraft engines (turboshaft and turboprops), which the company is the developer and manufacturer of. Compact simulator stands test all the functions of the regulator and allows you to abandon the use of bulky semi-natural stands, at least for 95% of the tests. The stand simulator is a hardware-software complex that simulates the engine as a system interacting with the regulator by simulating all analog, discrete and digital signals. The stand imitates the signals arriving at the regulator from sensors, aggregates, and engine systems that provide reception of control signals from the regulator. Besides, stand performs calculations and generates sets of interdependent parameter values (in the form of analog, discrete, and digital signals), each of which corresponds to one of the engine operating modes according to predetermined functional dependencies that reflect the characteristics of the engine – a mathematical model of the engine. The stands undergo certification in the scope of the program agreed with the State Enterprise “Zaporizhiastandardmetrology” and are verified by comparing the test results of the regulator on a simulator stand and as part of the motor stands of the Customer (engine developer). It is shown that the modular structure of the first of the simulator stands (basic) developed at the enterprise and the reserve provided for in its structure helped simplify its subsequent adaptation to the implementation of models of new types of engines. There is given the information on the stands simulating the AI-450M, AI-450S, AI-450S-1, AI-450T engines (for an unmanned aerial vehicle), and MS-500V-02S. It has been shown that simulator stands provide a set of tests for the development and serial production of regulators RDC-450M, RDTs-450M-S, RDTs-450M-S-1, RDTs-450M-C-T-P, RDTs-450S-500 at the enterprise.

An analytical synchronization for data of the transport diesel engines working process is a key issue of this publication. Of particular importance is that workflow data refers to engines in use. The lack of accuracy in determining the current characteristics of the working process is the cause of a significant error in determining power, fuel consumption, errors in monitoring the operation of engine systems, and its diagnosis. Calculation of the effective power of marine diesel engines is necessary not only to control the workflow and diagnose problems. It is also important for energy efficiency management as part of the Ship Energy Efficiency Management Plan (SEEMP). The task of analytical synchronization is formulated as the transfer of data of a function by time to a function by the angle of rotation of the crankshaft. In this case, it becomes possible to determine the top dead center (TDC) most correctly. As the basis of the method of analytical data synchronization for determining TDC coordinates, it is proposed to use the sequential execution of three stages: linear, sinusoidal, and differential (compression pressure’s first derivative is equal to zero). In addition, refinements have been made to linear and sinusoidal synchronization algorithms. They differ from their existing counterparts in using detailed restrictions. This allows one to have a further reduction of the error in TDC determining to a range of 0.1 ... 0.3 degrees of the crankshaft rotation. Also, this ensures the accuracy of the indicated power calculation and other basic workflow parameters with a maximum relative error of up to 2.5%. Obviously, such high accuracy allows avoiding diagnostic errors as much as possible, predicting the engine load, performing more exact calculations of parameters and characteristics, and taking measures to achieve higher energy efficiency and economy. Undoubtedly, this helps to increase the efficiency of both transport engines in general and marine engines in particular.

The dynamic processes in the rocket fairing when the pyrotechnic separation system is triggered are considered. The fairing construction is mixed and includes composite and metal elements. The main composite construction element is a fiberglass shell with regular and irregular winding zones. The speed acceleration required to separate the fairing occurs under the action of impulse pressure from the powder gases in the pyrotechnic system. The displacement of the fairing is made up of displacements of the movement as a rigid whole along its axis and vibrations caused by deformations. The calculation of the fairing movement is carried out according to a three-dimensional FEM model using software that uses a topologically regular discretization system. The problem solution in time is performed according to the implicit Wilson finite-difference scheme. When studying the fairing dynamics, it is allowed to break the structure of the shell in the form of lamination, which in the FEM scheme is modeled by a special method. A cut with double nodes is created on the surface of the proposed lamination along topological planes by transforming the finite element mesh. Modification of the stiffness matrix and mass matrix for the transformed mesh is performed based on the created information base of degenerate finite elements and formalized matrix operations. In numerical studies, two types of lamination from irregular zones of fiberglass winding are considered – the internal location from the flange and edge location with access to the fairing free edge. The results of calculating vibrations along the sides of lamination and data on the redistribution of dynamic stresses due to lamination are presented. Radial and axial displacements when passing through the lamination surface discontinue, the magnitude of which for internal lamination is much less, which is explained by the compression of deformation for this case, in contrast to the lamination that goes to the boundary. When estimating the relative axial displacements, the component of the displacement of a rigid whole, determined by a separate calculation, was excluded. The maximum radial displacements during lamination from the edge reach 3 mm, which is one and a half times higher than for an undamaged shell. Axial stresses are maximal from the action of inertial forces during acceleration. Its redistribution over the layers is significantly greater for the edge lamination, for which the maximum values increase almost two times concerning the undamaged shell, which determines this type of lamination as more dangerous.
