ENTRE LUTAS E ESPERANÇAS: os povos do campo e os projetos societários emancipatórios na América Latina
Authors: Sousa Maria Gorete de , Johnson Guillermo Alfredo
Published: December 2022

Para construir um projeto societário alternativo ao capitalismo desde a periferia se faz imprescindível recorrer ao pensamento crítico latino-americano. No século XXI, com a onda dos governos progressistas, muitas expectativas foram colocadas pelos movimentos dos trabalhadores, contudo para a maioria desses governos não estava colocada a ruptura e sim uma conciliação, que redundou no fortalecimento do modelo civilizatório do capital, aumentando a violência nas cidades e no campo. Encontramo-nos numa encruzilhada histórica, com uma nova ofensiva da potência hegemônica contra os latino-americanos. Ao mesmo tempo, as experiências das lutas e levantes dos trabalhadores, indígenas, quilombolas, extrativistas e camponeses se apresentam como marcas de distinção das resistências e possibilidades emancipatórias.

TELENOVELA AMBIVALENTE: a oscilação entre a dureza da hegemonia e os “mal ajustes” da decodificação
Authors: Rocha Larissa Leda Fonseca
Published: December 2022

Considerada o maior produto da Indústria Cultural brasileira a telenovela é uma ferramenta de fundamental importância para a compreensão da relação entre a lógica mercantil dos meios de comunicação de massa e práticas culturais e populares. Passam pela telenovela reforços inegáveis do pensamento hegemônico, mas algo a mais transita por lá, um modo de leitura e apropriação popular que a usa como veículo de novas práticas simbólicas e atribuição de sentido que permeiam as relações de poder - sempre tencionadas - entre dominadores e dominados.

Authors: Agriyanto Ratno , Fatoni Nur , Fuadi Nasrul Fahmi Zaki , Irfan Mohammad , Husnurrosyidah Husnurrosyidah
Published: December 2022

This paper aims at determining the psychological factors of bankers in implementing Profit and Loss Sharing (PLS) financing contracts in Islamic banks. The phenomenon of low occurrence of PLS financing motivated the researcher to write this paper. The theory of modified planned behavior is used to explain the research problem. The research data were obtained from 139 employees of Islamic banks in Indonesia and processed using SEM-PLS. The results show that trust has an effect on attitudes; subjective attitudes and norms affect intentions; perceived behavioral control has no effect on intention and behavior; intention influences behavior; and the perception of inefficiency has a negative effect on the relationship between intention and behavior. This paper contributes to the elaboration of the psychological factors affecting the behavior of bankers in implementing PLS. The implications of this paper for designing the strategies to improve the bankers' behavior in PLS financing are: the management must boost the bankers' confidence for the PLS financing benefits; the stakeholder’s social pressure is needed; the authority of bankers in implementing PLS financing needs to be increased; the bankers' access to the partner’s financial reports needs to be expanded; and the regulators need to give appreciation to Islamic banks that have a larger PLS portfolio.

Published: December 2022

Having a birth certificate and KIA is very important for every child to have as proof of identity. However, in reality, the number of birth certificates and KIA in Manokwari Regency is not proportional to the number of children. This study aims to classify children's data based on the number of birth certificates and ownership of KIA in Manokwari district by using the K-Means clustering method to produce sub-district groupings with high coverage of non-ownership of birth certificates and KIA, so that it can assist the Department of Population and Civil Registry of Manokwari Regency in provide targeted service programs. This study uses the Davies Bouildin Index (DBI) method to determine the optimum number of clusters used. The optimum number of clusters obtained is 4 with the lowest DBI value of 0.069 so that 4 clusters are formed, namely cluster 0 with a fairly low coverage category, cluster 1 with a fairly high coverage category, cluster 2 in a high coverage category, and cluster 3 in a very high coverage category. The K-Means clustering method succeeded in grouping sub-districts in Manokwari district, as well as informing the number of sub-districts with high coverage that do not have birth certificates and KIA.

One of the great potentials that can improve the economy of local communities is development in the tourism sector. Kepulauan Seribu is an archipelago area in the north of Jakarta, this area has tourism potential in the form of a cluster of islands. This group of islands has different characteristics to be used as a tourist attraction, including marine tourism, historical tourism and nature reserve tourism (conservation). Historical tourism in the Kepulauan Seribu has its own charm judging from the historical relics of the Netherlands before Indonesian independence. Islands that have historical tourism potential are the reason for conducting research related to the selection of tourist destinations in the Kepulauan Seribu, such as Kelor, Onrust and Cipir island. The obstacles of the community in finding the right tourism potential are still lacking information from the aspects of attractions, accessibility and facilities. To assist tourists in choosing a place, a decision support system is needed that can be completed using the Simple Additive Weighting method. There are five assessment criteria including scenery, photo spots, transportation, toilets and places to eat/resto. Determination of weights on criteria using a statistical approach from the questionnaire results shared with a likert scale. The result of the preferred tourist recommendation preference value is the island of Kelor because there are seven highest scores obtained by the island compared to Onrust island and Cipir island.

MS 4. - 6. yüzyıllarda, göçebe halkların (Hunlar) Asya'dan Avrupa'ya göçü olan “Büyük Halk Hareketi” gerçekleşti. Güney ve Orta Asya'da, Sasani İran, Gupta Hindistan ve birkaç küçük devlet de dahil olmak üzere büyük imparatorluklar vardı. Orta ve Güney Asya'da gizemli yeni halklar ortaya çıktı: Diğerleri arasında Aktalitler, Kidaritler, Chionitler ve Alhanlar. Kökenleri hala tartışılıyor. Bazı bilim adamları onların Hun halkları olduğunu öne sürerken, diğerleri her birinin farklı bir kökene sahip olduğunu öne sürüyor. Bu farklı bilimsel görüşler kısmen, bu döneme atıfta bulunan yazılı kaynakların yetersiz, parçalı ve bazen uyumlaştırılamayacak kadar çelişkili olmasıyla açıklanmaktadır. Arkeolojik malzeme de oldukça sınırlıdır ve tarihleme genellikle yaklaşıktır. Nümismatik keşifler bir ölçüde tarihin ilginç yönlerini ortaya çıkarıyor. Ancak, bu zorluklara rağmen, eldeki gerçeklerin toplanması, bu halkların Güney ve Orta Asya'daki tarihlerinin genel bir yeniden inşasına izin verir. D. Balogh'un editörlüğünü yaptığı yeni kitap (kapağında ve her bölümün başında harika bir Alkhan tamgası var), Orta bölgedeki Hun halkları (veya R. Göbl - İran Hunları'na göre) hakkında birkaç dilde metin kaynakları topluyor. ve Güney Asya, Willis'in Önsöz'de (s. VII) belirttiği gibi “hepsi burada ilk kez toplandı ve tercüme edildi”.

Authors: John Ace St , Kavic Stephen M.
Published: December 2022

Aim: The purpose of this study was to investigate if principles of Artificial Intelligence (AI), specifically Natural Language Processing (NLP), could be applied to the personal statements of general surgery residency applicants in order to gain valuable insight into the candidates and facilitate a more comprehensive assessment. Methods: The personal statements from individuals applying for a general surgery residency position during the 2021/22 application cycle (n = 1792) were analyzed using AI technology. Comparison groups were drawn from a database of documents from the general population and the personal statements of current general surgery residents (n = 64) at a single academic center. The study was conducted in collaboration with a leading language psychology and natural language processing organization. Results: Applicants exhibited a language-based personality that was highly self-assured (P < 0.0001) and trusting (P < 0.0001), and less stress-prone (P < 0.0001) and impulsive (P < 0.0001) than that of the general population. Compared to the general applicant pool, current residents were significantly more emotionally aware (P < 0.001) and organized (P < 0.001) and less self-assured (P < 0.001) and less driven by power (P < 0.001). Conclusion: Natural language processing technology can be utilized to assess the unique characteristics of general surgery resident applicants based on the content of their personal statements. In addition, candidates who successfully gain admission to a single academic program display different language-based personalities and drives compared to the general applicant pool. Incorporating these principles of artificial intelligence into the residency selection process could facilitate a more holistic evaluation of candidates.
EXTRACTION OF A COMPLEX TREND OF SIGNALS IN SYSTEMS OF INTELLIGENT SUPPORT OF THE MOVEMENT OF OBJECTS
Authors: Bouraou Nadia , Mishura Karyna
Published: December 2022

The article is devoted to the study of problems of intellectualization of control systems of moving objects to ensure their reliable operation in difficult conditions in various physical environments. Intelligent traffic support systems are developed based on the integration of measurement, computing, communication and control technologies and are designed to ensure the collection, accumulation and processing of information, determination of navigation parameters, formation of control influences, visualization of the positioning and movement trajectories of objects, monitoring of thefunctional state of objects and the state of the operating environment, etc. When restoring the lost trajectory of a moving object in the conditions of its complex movement, when approximating complex algorithms in adaptive control systems, with sudden changes in the trajectory or conditions of movement, there is a need to extract a complex trend from noiselike signals. The existing filtering algorithms do not provide acceptable efficiency, especially in conditions of limited a priori information about the nature of changes in the useful signal component.The article proposes and substantiates the use of wavelet filtering to suppress interference and extract the initial signal of a complex shape. A study of the effectiveness of extracting a complex useful signal against the background of Gaussian noise and harmonic disturbances was conducted. To process the simulated signals, wave functions of various orders from the families of Dobechies, symlets, and coiflets were used. The effectiveness of wavelet filtering was evaluated by the mean square deviation value of the selected trend and the model of the useful signal. The comparative analysis of the obtained results showed the feasibility of using the wave function of the family of symlets, which ensured the minimum value of the root mean square deviation of the selected trend from the model of the useful signal.
RESULTS OF SEMI-NATURAL TESTS OF THE AUTONOMOUS DETERMINATION OF THE VEHICLE LONGITUDE AND LATITUDE

Published: December 2022

Navigation parameters such as vehicle heading, linear speed and latitude and longitude are determined today, as a rule,using satellite navigation systems. However, there is a need for autonomous determination of navigation parameterswhen satellite navigation system signals are unavailable for one reason or another. For example, satellite navigationsystem signals can be jammed by electromagnetic countermeasures.Autonomous systems for determining the vehicle navigation parameters are inertial navigation systems, the basis ofwhich is the double integration of signals from accelerometers, as well as the integration of signals from gyroscopes toform one or another coordinate system, if we are talking about strapdown inertial navigation systems (SINS).Integration of the output signals of accelerometers and gyroscopes, which contain errors, leads to the accumulation ofSINS errors. To increase accuracy, SINS are integrated, for example, with satellite navigation systems. However, suchsystems cease to be completely autonomous.The article uses the method of autonomous determination of vehicle latitude and longitude, which is a new method ininertial navigation. The method is based on the strapdown inertial technology, which, unlike the standard methods usedin SINS, does not use the integration of the output signals of accelerometers and gyroscopes. To determine the angles oflatitude and longitude, the signals of the gyroscopes included in the inertial measurement unite (IMU) are used.As a result of a semi-natural experiment, the efficiency of the method of autonomous determination of latitude andlongitude was verified. Flight data of a small-sized aircraft were used for experimental verification. The data containedinformation about the angles of the heading, pitch, roll of the aircraft, the output signals of three micromechanicalgyroscopes, three micromechanical accelerometers, information about latitude, longitude and altitude measured by thereceiver of the satellite navigation system, as well as information about the horizontal and vertical components of speedand current time. Plots of calculated values of latitude and longitude and values measured using the receiver of thesatellite navigation system are given. From the given plots and tables, it can be seen that from a certain time, thecalculated values coincide with the "reference" ones, which confirms the efficiency of the method of autonomousdetermination of latitude and longitude.
ENERGY CALCULATION OF SMALL-SIZED UAVs AUTOMATIC OPTOELECTRONIC OBSERVATION SYSTEMS
Authors: Kravchenko Igor , Mykytenko Volodymyr , Vasylchuk Yelizaveta
Published: December 2022

Great popularity of small unmanned aerial vehicles (UAVs) in remote observation tasks requires further improvement of not only the carrier, but also the on-board equipment. Standard means of surveillance for UAVs are television cameras. Thermal imaging cameras are used in more expensive technical solutions. The efficiency of the functioning of these devices primarily depends on spatial and energy resolution of their input units, which containe optical system and detector. Small-sized UAVs operate at short distances. The peculiarity of useful signal formation by optical-electronic surveillance systems (OESS) of such UAVs is the need to primarily ensure sufficient energy sensitivity.

The article develops a method for determining the energy resolution of short-range automatic UESs with two information channels - television and thermal imaging. It is justified that for simplified calculations it is advisable to use the functions of the noise-equivalent luminance difference and the noise-equivalent temperature difference of the corresponding channel as quality indicators. Examples of energy resolution calculations of television and thermal imaging channels of the OESS with matrix detectors are given. The influence of focal length and of entrance pupil diameter of the lenses on the energy resolution was studied for observation distances from 0.5 km to 2 km. It is shown that, in OESS with variable magnification, lenses with a larger diameter of the entrance pupil are preferred - they provide more uniform energy sensitivity when changing the focal length. The developed calculation methods can be used for multispectral OESS operating in the visible and infrared spectrum ranges.
MATHEMATICAL MODEL OF PNEUMATIC CHANNEL OF GAS PRESSURE MEASURING TRANSDUCER
Authors: Matiko Fedir , Kostyk Ihor , Matiko Halyna , Onysyk Stefan
Published: December 2022

The paper is devoted to the study of the impact of operational factors, particularly gas leakage through the damages of pneumatic channels of measuring transducers of gas pressure and pressure drop, on the measuring result of these parameters and, therefore, on the measured value of gas flow rate and volume using pressure differential flowmeters. During the operation of gas metering units, connecting tubes, valve blocks, and averaging chambers of the standard primary device must be hermetic. However, they may become non-tight because of operational factors, and gas leakage may occur. Such leaks distort the measured pressure drop or pressure value, which can lead to a distortion of the measurement result of the gas flow rate by the metering unit.
The authors developed a mathematical model of a pneumatic channel of gas pressure measuring transducer with existing damage. For this purpose, a mathematical model of the connecting tube, which connects the pressure averaging chamber with the pressure transducer chamber, has been developed for the stationary gas mode. A mathematical model of gas leakage through damage like "through-hole" was also developed. Based on the mathematical model of the connecting tube and the model of the process of gas leakage through the hole, a mathematical model of the pneumatic channel with a gas leakage hole was obtained.
Modeling and investigating the impact of gas pressure, geometric characteristics of damage, and connecting line on the measuring result of pressure or pressure drop was performed. Particularly, the value of the negative systematic error of the gas pressure measurement, which occurs as a result of gas leakage through the hole in the connecting tube, is calculated for a set of fixed values of the geometric characteristics of the pneumatic channel.
The paper shows that an increase in the pressure in the measuring tube leads to an increase in the modulus of pressure absolute error caused by the gas leakage through the hole in the connecting tube. The gas flow rate through the hole in the connecting tube and, accordingly, the pressure measurement error depends on the diameter of the through-hole and the location of the leakage. An increase in the hole diameter leads to an increase in the modulus of the absolute error of the pressure measurement.
As the length of the connecting tube from the connection point with the measuring pipeline to the point of gas outflow increases, the pressure measurement error increases by the modulus.
SOFTWARE DEVELOPMENT FOR AUTOMATED DESIGN OF FLOW METERS
Authors: Kolomiiets Kostiantyn , Gryshanova Iryna
Published: December 2022

This work presents the development of a software complex for the automated design of variable pressure drop flowmeters. It includes flowmeters with standard primary devices, namely a diaphragm, nozzles and a venturi tube. To fulfill the task, a review of various software solutions has been conducted. As a result, it was concluded that the existing software does not fully solve the task, because it does not calculate most of the design parameters for metering device. The next stage was a review of the flow rate measuring method by variable pressure drop, and based on it, a mathematical model of flow meters has been implemented taking into account the existing standards. Next, the initial geometric parameters of the flow meter were evaluated and the parameter selection algorithm for the diaphragm with pressure taking chambers was given.

As a result of the performed analysis, developed software allows you to conveniently enter input parameters, such as flowrate, pressure drop, pipeline diameter, type of constriction device, method of pressure selection, and at the output receive a corresponding schematic image of the flowmeter with all design parameters and the flow calculation formula, based on the pressure difference. For a better understanding of the software operation, an overview of it was offered and an example of a nozzle calculation has been demonstrated.

The implementation of the created software application makes it possible to increase the accuracy of the accounting of consumed resources, and also reduces time and money costs for measuring instrument development.

In the future, it is planned to create the software complex by adding to it the design capabilities of calorimetric, ultrasonic flowmeters and rotameters, as well as special software for selecting the most optimal flow measurement method based on the specified parameters of the measured medium, pipeline diameter and flow measurement range.

Therefore, it will be possible to carry out metrological control and supervision of such measuring complexes, develop and certify methods for measuring the flow of liquids and gases.
DETERMINATION OF DIAGNOSTIC SIGNS OF MULTIPLE SCLEROSIS USING TONTOR STEP MODEL
Authors: Skytsiouk Volodymyr , Klotchko Tatiana
Published: December 2022

The conducted theoretical studies provide a basic thesis regarding the creation of a generalized concept of diagnosis of the signs of multiple sclerosis, which should determine the parameters of the distortion of the idealized model of the body system by the real nature of the disease and the state of the object.

The work presents an analytical model for determining the onset of the disease using the TONTOR step model.

The proposed method provides the doctor with information, excluding the subjective factor, while the results of such information technology significantly increase the accuracy of determining the early stage of the disease. Purpose of work consists in modeling the diagnostic signs of appearance of multiple sclerosis at an early stage of development, and appearance of moment of action's onset of this pathology by analysis methods.

With this method of modeling, we have the opportunity to use affine and conformal transformations, which were considered earlier. In this case, the chord should be perceived as a directional vector with location accuracy. A circle is a consequence of an affine transformation. Thus, we have the opportunity to set the coordinates of the points of the trajectory and the circle in an unambiguous correspondence. In addition, since the real motion along the trajectory is characterized by oscillatory processes, the affine transformation of the model can be imagined as an exponential curve.

The proposed physical and mathematical information processing models will help determine the main points of creating the principles of operation of technical integrated diagnostic tools. The basis is a vector model for determining the state of biological objects, which will allow information signals to be determined with help of integrated TONTOR sensors and TONTOR step model.

As a result, the study of the nature of this functional dependence will provide analytical dependences in digital form, will allow the creation of a computer-integrated hardware solution that will eliminate subjectivity in diagnostics according to the "bad - good" principle.

Published: December 2022

Thermal radiation from various sources is widely used in medical therapy procedures. Sources of artificial and natural origin are used to create thermal radiation. The latter are of the greatest interest, as they form a wide spectrum of radiation, most comparable to a person's own radiation. The use of wormwood cigars (mox) became widespread. With their help, sessions of one of the most popular methods of Chinese folk medicine, moxatherapy (burning, thermopuncture, "jiu" therapy) are conducted. The authors conducted studies of the thermal radiation of a wormwood cigar in the wavelength range of 800…1000 nm. "Qiaitiao" No. 6 cigars from the standard treatment set were used for experimental research.

The purpose of the conducted research is to determine the power of thermal radiation of moxa and evaluate the dynamics of its changes during the course of a treatment session. A high-precision OM3-65 absorbing power wattmeter with an optoelectronic converter was used for measurements. Studies have shown that the maximum power of thermal radiation is formed immediately after the wormwood cigar begins to smolder. Its value is within (1.5...2.0) 10-4 W. When a cigar burns for 2.5 minutes, the intensity of heat radiation decreases by more than an order of magnitude. This is due to the fact that in the process of smoldering moxa, a layer of ash is formed between the burning and irradiation zones, which partially absorbs the flow of thermal radiation. In addition, during decay of fixed moxa, the irradiation zone gradually moves away from the irradiated surface.

Removing the ash layer and placing the moxa at the previous distance leads to the restoration of the initial power level. Approximate expressions were obtained, which, based on experimental data, describe the change in the heat radiation power of a wormwood cigar.

The features revealed during the study of the thermal radiation of the wormwood cigar will be useful for specialists engaged in practical thermotherapy and will contribute to increasing its effectiveness.

Introduction. Benign prostatic hyperplasia (BPH) is characterized by the occurrence of disorders of urine storage and bladder emptying. Most men over the age of 60 years are affected to some degree. Transurethral laser resection of the prostate (TURP) is minimally invasive, endoscopic and one of the modern technologies of biomedical engineering, which can cause minimal harm to patients and is recognized as the "gold" standard in urology. It is widely used for the treatment of BPH complicated by acute urinary retention.

Main part. The management of patients with BPH is complex. Emptying and retention disorders can be treated by various pharmacological and surgical means. The article provides data on the experience of combining the technology of transurethral laser resection with medical postoperative therapy to reduce complications. Using the example of postoperative use of “Levofloxacin” in 179 patients, the effectiveness of this combination was proven.

Conclusions.

       1. Minimally invasive transurethral laser resection of the prostate gland is one of the promising methods of prostate treatment, which significantly reduces risks for patients and is recognized as the "gold" standard in urology. Laser endoscopic resection of the prostate is one of the modern technologies of biomedical engineering.

The result of surgical treatment of patients with benign prostatic hyperplasia by laser resection largely depends on the appointment of adequate postoperative antibiotic prophylaxis.

The combination of the laser resection method with the postoperative use of levofloxacin in patients with benign prostatic hyperplasia complicated by acute urinary retention allows to improve the results of surgical treatment by reducing the development of complications in the postoperative period by 1.6 times.

Сучасні тенденції розвитку поліграфічної галузі повністю залежать від вимог і специфічних вподобань покупців. Паковання повинно не тільки надійно захищати товар від пилу та забруднень, а й забезпечувати тривале зберігання товару, захист від вологи та ультрафіолету, бути міцним та естетично привабливим. Технологічний процес ламінування пакувальної продукції проводиться з метою покращення її зовнішнього вигляду та бар’єрних властивостей матеріалів, захисту та підвищення гладкості, надання глянцю або матовості. Ламінування дає можливість надійно захищати паковання з картону від забруднення та механічних пошкоджень, таким чином збільшуючи його довговічність. Паковання з ламінованого картону стійке до зовнішніх механічних впливів, особливо на місцях зрізів та бігування. Виготовлення якісної пакувальної продукції, дослідження її експлуатаційної стійкості, підвищення рівня поліграфічного оформлення з метою задоволення високих естетичних запитів споживачів є актуальним завданням фахівців поліграфічної галузі.
В роботі досліджено експлуатаційні та репродукційно-графічні показники відбитків цифрового друку, отримані на популярних марках картону, представлених на українському ринку поліграфічних витратних матеріалів, до та після процесу їх ламінування глянцевою та матовою плівкою. З метою оцінювання якості та точності відтворення кольорового зображення побудовано графічні залежності градаційної передачі фарб та їх колірного охоплення, які свідчать, що координати кольору усіх досліджуваних зразків знаходяться в регламентованих межах, а ламінування поверхні відбитків як матовою, так глянцевою полімерною плівкою, значно покращує їх колірне охоплення. Крім того, результати проведених експериментальних досліджень стійкості до розриву підтвердили, що ламінування відбитків суттєво впливає на підвищення їх експлуатаційної стійкості. Також встановлено, що характеристики використовуваної плівки впливають на міцність отриманих в результаті ламінування відбитків.
Онлайн-навчання редакторської майстерності: огляд українських і зарубіжних онлайн-курсів

У статті розглянуто змістове наповнення та принципи функціонування українських та зарубіжних онлайн-курсів для опанування редакторської майстерності. Під час навчання онлайн редактор може здобути нові фахові знання або ж підвищити свою кваліфікацію. Такі курси забезпечують гнучкість навчання та задовольняють потребу редактора в безперервному професійному вдосконаленні в умовах пандемії COVID-19 та військових дій в Україні. Мета статті — узагальнити український і зарубіжний досвід онлайн-навчання редакторської майстерності, дослідивши тематичне наповнення сучасних професійних онлайн-курсів. У науковій розвідці було використано аналітико-синтетичний, структурно-функціональний методи дослідження, а також типологічний аналіз для виокремлення тематико-типологічних груп онлайн-курсів. Ми розглянули освітні програми 13 українських та зарубіжних онлайн-курсів, де під час навчання студенти мають змогу ознайомитися з основами редакторського фаху, обов’язками редактора у видавництві, композиційним, мовностилістичним редагуванням, з процесом коректури тексту. Крім того, майбутні фахівці розвивають такі навички, як креативність, критичне мислення, уміння передбачати результат своєї діяльності, планувати власну роботу та діяльність видавничого колективу, швидко і гнучко реагувати на нові тенденції у професії. Однак ґрунтовну системну підготовку редактори можуть здобути лише у ЗВО, де навчання редакторської майстерності триває довше та є більш фундаментальним. На відміну від освіти в університеті, онлайн-курси дають лише фрагментарні знання та не можуть сформувати в редактора цілісної картини редакторської професії.

У статті аналітично узагальнено вектор-параметричну та Мюллер-матричну поляриметрію оптично анізотропних фазово-неоднорідних шарів з полікристалічною архітектонікою. Основними оптичними властивостями таких матеріалів є механізми лінійного та циркулярного двопроменезаломлення та дихроїзму полікристалічної архітектоніки. Нами запропоновано та аналітично обґрунтовано новий експериментальний оптичний метод 3D-матриці Мюллера томографічного відтворення координатних розподілів випадкових значень величини параметрів лінійного та кругового двопроменезаломлення та дихроїзму частково деполяризуючих полімерних плівок у видавничо-поліграфічній справі. Основна ідея цього поляризаційно-томографічного методу базується на сукупності аналітичних та експериментальних принципів. Отримано аналітичні вирази для томографічної реконструкції координатних розподілів випадкових значень величини параметрів фазової та амплітудної анізотропії полікристалічної архітектоніки полімерних матеріалів за даними експериментального багатоканального Мюллер-матричного картографування промислових зразків. Синтез техніки координатного Мюллер-матричного сканування полімерних матеріалів із принципами лазерної поляризаційної інтерферометрії забезпечив можливість експериментальної реєстрації розподілів інтерференційних картин, пов’язаних із фазовою структурою об’єктного лазерного поля. Застосування алгоритмів цифрової голографії — прямого та зворотного Фур’є перетворення — забезпечило можливість відновлення розподілів полів комплоексних амплітуд у різних фазових площинах. В результаті реалізовано пошарове фазово-голографічне отримання коорлінатних розподілів випадкових значень величини елементів матриці полімерного Мюллера шару. В рамках статистичного аналізу отримано об’єктивні критерії, які характеризують карти лінійного та циркулярного двопроменеломлення та дихроїзму.
