Published: April 2022

The article presents thermogravimetric studies of cotton textile material before and after printing by thermal transfer printing. Thermal transfer printing on garments and knitwear, umbrellas, bags, advertising banners, posters, etc. is popular. Transfer printing technology involves the transfer of the image to the textile material using an intermediate medium. First, the desired image is formed on a special paper or film using screen printing. Then, with the help of temperature in special presses, it is transferred to the textile material. If the image is multicolored, the whole process is repeated separately for each color. Heat transfer technology allows to apply high- and multi-color images to finished products or semi-finished products with high accuracy; to carry out personalized printing. Since thermal transfer printing involves the presence of high temperatures to obtain an image on the material, a comprehensive thermal analysis of cotton fabric was performed before and after printing. A test scale with a raster line from 100 to 140 lines / cm was used for research. Densitometric indicators of quality of the formed thermotransfer images by plastezol paints are given. It is established that with the increase of the line of raster images the color indicators of the prints on the textile material decrease slightly, which must be taken into account when fulfilling orders in industrial conditions. Using electron microscopy, the process of interaction of dye with cotton fibers in the fixation of printed images was studied. Significant influence on the quality of prints on textile material of surface structure of cotton fibers, their structure, dye composition and printing modes is confirmed. It is established that cotton fabric with printed image at 140 oC provides high quality color printed thermal transfer images. This is confirmed by such qualimetric indicators as optical density, image contrast, brightness. Modeling the mechanism of fixing the printed image on the fabric during thermal transfer printing can be divided into four stages: diffusion of the dye from the environment to the surface of the fibers; sorption of the dye on the surface; diffusion of dye inside the fiber; sorption of the dye on the inner surface of the fiber, which require more detailed and in-depth studies.

The development of software components for computer determination of thread tension on winding machines, in the preparation of the base using the recursion algorithm, allows at the initial stage to determine the technological loads that will occur during warping depending on the type of raw material, quality of spool preparation. Computer determination of the change in relative tension on dream machines in the preparation of the basis for the manufacture of multilayer technical fabrics for special purposes is based on the numerical solution of transcendental equations using recursion and dichotomy algorithms. Calculation of changes in relative tension on winding machines in the preparation of the basis for the manufacture of multilayer technical fabrics for special purposes allows at the initial stage to determine the technological loads that will occur during warping depending on the type of raw material, quality of spool preparation. The change of tension occurs due to the interaction of the warp threads with the guides of the winding machines of large and small curvature, tensioning devices. The development of software components in the computer determination of thread tension on spinning machines should be based on the use of object-oriented programming languages. Determining the change in relative tension in the refueling zones of the sweeping machine, taking into account the design of the unit for tension, will improve the technology of warping in the preparation of the basis for the manufacture of multilayer technical fabrics for special purposes. Improvement of technological processes of warping should be based on complex researches of process of interaction of warp threads with devices for a tension, directing surfaces of big and small curvature. Theoretical dependences of the warp tension will allow to obtain mathematical software used in a computer program to calculate the change in relative tension in the refueling zones of the spinning machine, reduce the percentage of breakage of warp threads, improve the quality of weaving thread. Many studies do not take into account the change in the input tension of the warp thread when it is wound from the spool. This leads to significant differences between the theoretical and experimental dependences of determining the change in relative tension in the refueling zones of the dream machine, which does not allow to obtain reliable results.

The result is the creation of methods for calculating the tightness (duration of gas flow) in non-lubricating cylinder-piston metal-polymer seals, as well as assessing the accuracy of the created methods for piston seals. The article considers the elastic contact of a strongly anisotropic rough surface (polymer surface) with a smooth (metal) surface. The dependence of the intercontact gas volume on the complex of contact conditions based on the theory of stochastic fields is investigated. An estimate of the error that occurs when replacing the exact formula for calculating the contact volume with an approximate formula is performed. The values ​​calculated according to the exact and calculated formula of the consolidated inflow differ by no more than 0.17 percent. Accurate methods for calculating the tightness of non-lubricating cylinder-piston seals for molecular and viscous modes of gas flow, which is the basis for practical calculations of the tightness of the seals of non-lubricating pneumatic compressors, are theoretically substantiated and developed. The dependence of the contact volume, the effective level of deformation and the average height of the gap on the set of contact conditions has been studied. It is established that at low loads the deformation level, the effective deformation level, the reduced contact volume and the reduced average gap height are numerically equal. The values ​​calculated by the exact and calculated formula of the contact volume differ by no more than 0.17 percent at K 1 and no more than 0.00029 percent at K> 1.

The scientific article is devoted to the issues of SDR system control. Software Defined Radio is a system designed for software control of information transmission processes in a radio communication channel. Recognition of digital modulation types is used, which automatically classifies the type of digital modulation of the received signal. The following issues are covered in the article: the analysis of existing approaches in the task of automatic recognition of types of digital modulation is carried out; the analysis and classification of informative features in the task of automatic recognition is carried out the following types of digital modulation: 2-PSK, 4-PSK, 8-PSK, 2-FSK, 8-QAM, 16-QAM, 64-QAM and OFDM. This article uses a neural network approach based on cumulative characteristics. To solve these problems, the methods of calculation and selection of informative cumulative features described in the developed model of the system of automatic recognition of digital modulation types by means of a neural network on cumulative features at a known value of carrier frequency are described. A model of the system of automatic recognition of digital modulation types at a known value is constructed carrier frequency. An algorithm for automatic recognition of digital modulation types has been developed using a multilayer neural network. The influence of noise in the communication channel on the probability of recognizing the types of digital modulation at a known value of the carrier frequency is investigated. It was found that regardless of the type of noise in the communication channel, the law of error distribution in IQ data becomes close to normal. This fact is one important argument for the use of cumulative features in the task of automatic recognition of types of digital modulation. Therefore, the task of automatic recognition of digital modulation types is quite relevant. Further research may be aimed at expanding the range of high-order cumulative features used, due to which it is possible to increase the probability of correct recognition of types of digital modulation, and solving the recognition problem at an unknown value of the frequency and initial phase of the carrier signal.

Published: April 2022

The work is aimed at solving a relevant for Ukraine and the world scientific and applied problem – the development of methods and means of constructing a psychophysical portrait of man to determine its stress resistance. For a number of professions, special methods of selecting personnel for special abilities are needed. Such abilities (qualities) include: health; motivation and will to act decisively, with the maximum effort of their physical, intellectual and psychological capabilities; physical training; level of mastery of technical means (or other means necessary in a critical situation); temperament; nature; emotional condition; accumulation of fatigue during the task and others. The article develops a method for classifying users according to the level of stress resistance on the basis of a modified auto-associative neural network using the Fletcher – Reeves algorithm. There are several ways to classify stress responses, but a more obvious study is to divide them into behavioral, intellectual, emotional and physiological manifestations of stress. The main signs of behavioral stress are psychomotor disorders (excessive muscle tension, winter breathing rhythm), lifestyle changes (changes in daily routine, sleep disturbances), occupational disorders (decreased productivity, increased fatigue), impaired social role functions, increased conflict, increasing aggression, etc.). In conditions of constant influence of stress factors on human consciousness, the decision can be ill-considered and made under the influence of emotions. To avoid such a situation in the workplace, the head of the company must monitor the condition of the operator. This human operator stress assessment system has been developed to predict human operator stress. The main task of the model is to predict based on the obtained parameters of the human condition (stress or not). Additional testing was added to increase the model’s performance based on input data on physical parameters, gender, age, height, and bad habits. The purpose of testing is to increase the accuracy of model prediction. Data from 92 respondents with 1180 records were selected for testing. Data set division: testing – 20 %, training / verification – 80%. The best results were achieved with the help of our own developed neural network based on Keras. Also in the paper the implementation of decision-making methods, the method of k-nearest neighbors and the modified auto-associative network was presented.

In the modern world, a lot of things and processes, which not so long ago were treated as something from fiction, are increasingly being implemented in real life. An example of this is the automation of the process of recognizing emotions, which is no longer an unattainable technology and occupies an important place in the area of computer vision. Technologies for recognizing the emotions of facial expression can be used for various fields and purposes: from creating games and applications to more complex, such as analysis of people’s mental state, discussions, marketing research, attention monitoring, driver status, robotics and so on. All this confirms the high academic and commercial potential of systems for recognizing the emotional characteristics of the person and, accordingly, brings a large number of scientists and developers, some of whom have already implemented such systems. But today their number is small and a lot of such products require special equipment and high computing performance. Another common problem is the vulnerability to blurred images and the closed nature of the system, which makes it impossible to analyze and modify the development. Therefore, the optimization of the automated process of recognizing the emotions of facial expression is needed in order to create a more stable, high quality and affordable system. The paper have description and results of the creation of system of emotion recognition, the basis of which is a convolutional neural network. The user can connect with the system through a simple interface that allows you to download the image for analysis or turn on the camera to identify emotions in real time. The practical value of this work is the developed high-quality system for recognizing the facial emotional characteristics which is ready for use and implementation in relevant fields.

Today, the main activity of Ukrainian electricity companies is to meet the ever-growing needs of Ukrainian consumers in quality and reliable electricity supply. For this purpose, constant work is carried out on the reconstruction of electrical networks and construction of new energy facilities on the basis of a new regulatory framework adapted to world standards. The article proposes to determine the location of damage to a branched power line with several power sources, namely, to create a device for diagnosing power lines. The device for diagnosing power lines is designed to isolate the damaged branch in the branched overhead power lines, and measure the distance to the place of damage. The operation of the device is that the meters of inhomogeneity of cables and lines measure the delay time of the probing pulses reflected from the place of damage of the branched power lines, from the beginning of the main line and from its end. Next, the total delay time of the probing pulses reflected from the place of damage of the branched transmission line is compared with the time of passage of the probing pulses on the main transmission line, if the delay time is equal, the damage is on the main transmission line. branch. Then, based on the obtained measurements, the exact location of the damage on the power line is calculated. The technical result is to increase the accuracy of determining the location of damage on branched transmission lines with multilateral power supply by attracting a priori information (known all the inhomogeneities of a good transmission line) and the location of the transmission line inhomogeneity (branching) and measuring . The proposed approach does not involve the use of specific instruments for measuring current and voltage values, but is based only on measuring the delay time of probing pulses using line inhomogeneity meters. Determining the importance of constant diagnostics of the technical condition of power lines in the article shows one of the real ways to create a remote diagnostic device that can be implemented on modern elements and computer technology.

With the traditional method, 1 worker can only produce 1.5 kg/hour of candlenut. When it rains, the candlenut cannot be dried in the sun, so the production of candlenut stops. Candlenut which is not completely dried, cannot produce quality candlenuts when cracked. This study aims to increase the quantity and quality of the candlenut seed production through the design of an integrated drying and filter component of the pecan shell separator using the 3 variable machine capacity test method (drying temperature, drying time and motor rotation) needed to produce optimal conditions for production candlenut. Test This research succeeded in increasing the production of candlenut from 36 minutes/kg to 2.5 minutes/kg. However, this trial has not produced a better quality than the traditional method, where the results of the whole candlenut use 16 % machine, while the traditional method is 70 %. Until now, the best variables we have obtained for separating the candlenut shells on this machine are the drying temperature of 123.4 â°C, the drying duration is 60 minutes, and the rotating speed of the motor is 1800 RPM.

For calculating the expected ruin time of the classic three-player symmetric game, Sandell derived a general formula by introducing an appropriate martingale and stopping time. However, the martingale approach is not appropriate to determine the ruin time of asymmetric game. In general, ruin probabilities in both cases, that is, symmetric and asymmetric games as well as the expected ruin time for the asymmetric games are still need to be calculated. The current work is also about three-player gambler’s ruin problem with some extensions. We provide expressions for the ruin time with or without ties when all the players have equal or unequal initial fortunes. Finally, the validity of the asymmetric game is also tested through a Monte Carlo simulation study.

З метою аналізу спроможності відділу прикордонної служби до виконання завдань за призначенням пропонується використовуватиметодику підрахунку службового навантаження посадових осіб, завершальним етапом якої є формування необхідних для виконання завдань за призначенням сил та засобів відділу прикордонної служби. Співвідношення між розрахованими та наявними силами та засобами відділу прикордонної служби визначає спроможність прикордонного підрозділу виконувати завдання за призначенням. На основі дослідження на прикладі посади начальника відділу прикордонної служби підсумовано, що визначений керівними документами обсяг службового навантаження розрахований на 3 зазначених посади. За такого результату рекомендується проаналізувати якісну та кількісну компоненту та здійснити перерозподіл або делегування окремих повноважень начальника підрозділу охорони кордону.

Diera digital saat ini, hampir seluruh kegiatan yang dilakukan oleh manusia tidak akan terlepas dari teknologi. Termasuk dalam transaksi jual beli atau yang lebih dikenal dengan e-commerce. Kini telah hadir banyak plaform e-commerce di Indonesia. salah satunya yaitu Shopee yang hadir sejak tahun 2015 yang hingga agustus 2021 telah 26,92 juta pengguna harian. Shopee memiliki banyak fitur yang memudahkan transaksi jual beli. Namun, dalam transaksi shopee terdapat biaya penanganan yang dibebankan kepada customer. Lalu, bagimana islam memandang transaksi jual beli online pada Shopee? Penelitian ini menggunakan metode penelitian kepustakaan (library research). Dalam penelitian kepustakaan, penelusuran pustaka yang dilakukan lebih dari sekedar menyiapkan kerangka penelitian atau proposal guna memperoleh penelitian sejenis, memperdalam kajian teoritis ataupun mempertajam metodologi. Penelitian kepustakaan dilakukan untuk memperoleh berbagai macam data yang diperlukan dalam penelitian. Dalam fiqih muamalah yang mengatur hukum berjual beli. Jual beli online di Shopee hukumnya boleh karena syarat dan rukunya terpenuhi. Namun, menjadi haram saat transaksinya mengunakan fitur Shopee PayLater karena didalamnya mengandung unsur riba. Serta etika dalam berbisnis juga belum semuanya memenuhi prinsip etika bisnis islam.
On the Current Situation of Creative Industries in Turkey
Authors: DEMİR Erman M.
Published: April 2022

The Creative Industries [CI] have become an increasingly popular political and academic discussion topic in the world over the past three decades. In Turkey, it is a concept that has come to the fore recently and is the subject of relatively few academic publications. Although it is noteworthy that the studies on the subject in Turkey have started to enrich, especially in the last five years, it is quite optimistic to say that a solid discussion ground has been established. In the field of public policy, there are many efforts that explicitly or implicitly refer to the idea of ​​CI. On the other hand, it seems that CI are not defined as a holistic and coordinated policy area. In the light of the presumption that the potential changes created by CI, especially its social effects, are handled without questioning, it can be stated that the relations of unique cultural values to sectors have become complicated. This study is a compilation made in order to lay the groundwork for the realization of original studies on the creative sectors, to add dimension to the CI discussion and to draw attention to policymaking on this issue.

ФОРМУВАННЯ ТА РОЗВИТОК ПЕДАГОГІЧНОЇ ТВОРЧОСТІ ВИХОВАТЕЛЯ ЗАСОБАМИ САМОРОЗВИТКУ
Authors: КУРЧАТОВА Анжеліка
Published: April 2022

У статті проаналізовано психолого-педагогічну літературу з питання формування та розвитку педагогічної творчості вихователя засобами саморозвитку. Розкрито сутність понять «педагогічна творчість», «творча діяльність», «саморозвиток». Схарактеризовано основні умови для формування педагогічної творчості засобами саморозвитку. Обґрунтовано важливі якості творчої особистості. Актуальність дослідження обґрунтовано визначенням протиріч між: об’єктивною потребою суспільства в оригінальних і високоефективних підходах педагога до освітніх завдань і високим рівнем адміністрування в системі дошкільної освіти; сучасними запитами щодо креативності педагогічної діяльності та жорсткої регламентації її в освітньому просторі сучасного закладу дошкільної освіти; необхідністю розкриття творчого потенціалу дитини та суб’єкт-об’єктним стилем педагогічної взаємодії. Педагогічна творчість представлена як пошук педагогом нових рішень у постановці нових завдань, застосуванні нестандартних прийомів діяльності, здатності передбачати та оптимально вирішувати своєрідні проблемні ситуації, що виникають у роботі вихователя. Сучасний заклад дошкільної освіти потребує вихователя, який готовий працювати в умовах інноваційних змін, що відбуваються в освіті, продукувати нові ідеї щодо організації педагогічного процесу, ініціювати та реалізовувати творчі проекти, проявляти творчі вміння, створювати таке освітнє середовище, яке було би комфортним для дитини, сприяло розкриттю її потенційних можливостей розвитку, виховувало творчу особистість. Ідеться про вихователя-дослідника з новим педагогічним мисленням, креативного фахівця, гуманіста й оптиміста за переконанням, який бачить дошкільне дитинство в усій його унікальності, а заклад дошкільної освіти – у різноманітності творчих підходів до виховання дітей. Такий вихователь уміє знаходити в роботі з дітьми нові ресурси, продукувати ефективні форми, способи спілкування та взаємодії з ними. Результатом творчості вихователя є зростання його професійної майстерності та особистісний саморозвиток, стимулювання творчої ініціативи вихованців та їхньої пізнавальної активності.
ВПЛИВ КРИЗ ПСИХОВІКОВОГО РОЗВИТКУ НА ВИНИКНЕННЯ НЕГАТИВНОЇ ПОВЕДІНКИ У ДІТЕЙ ДОШКІЛЬНОГО ВІКУ
Authors: МЕЛЬНИКОВА Ольга
Published: April 2022

У статті порушується проблема, викликана потребою суспільства у формуванні сучасного молодого покоління. Мета статті полягає у висвітленні впливу криз психовікового розвитку на виникнення негативної поведінки у дітей дошкільного віку. Виокремлено, проаналізовано погляди та узагальнено ідеї відомих дослідників щодо порушеної проблеми дослідження. У разі несприятливого перебігу кризи необхідно здійснювати психолого-педагогічний супровід дитини дошкільного віку, актуальність якого підвищуватиметься у зв'язку з акцентуванням на завданнях позитивної соціалізації, що простежується в освітніх програмах дітей дошкільного віку. Найбільш поширеними негативними проявами, які спостерігаються у дошкільному віці, є: примхливість, впертість, агресія, афективні спалахи, істерики, страхи, неслухняність, нечесність, жадібність, замкнутість, сором’язливість, кожен з яких має певні особливості прояву. Суттєвими є й інші симптоми криз у дітей, такі як негативізм, впертість, емоційне збудження, норовливість, свавілля та інші негативістські симптоми. Визначено психолого-педагогічні умови, дотримання яких уможливить попередження виникнення негативної поведінки у дітей дошкільного віку у період перебігу криз психовікового розвитку. Закцентовано увагу на тому, що, аби допомогти дитині дошкільного віку успішно пережити психовікові кризи, необхідно побудувати навчально-ігрову діяльність на основі корекційно-розвивальних ігор. У період кризи можуть сформуватися як позитивні, так і негативні новоутворення. Таким чином, вплив криз психовікового розвитку на виникнення негативної поведінки у дітей дошкільного віку є актуальною проблемою сьогодення, оскільки вони можуть сприяти формуванню негативних проявів поведінки у дошкільників.
