Authors: Garip Sevinç , Çetinalp Sibel , Aşut Elife
Published: December 2024

Objective: In pediatrics, colonoscopy is routinely used safely and effectively for the diagnosis and treatment of gastrointestinal system diseases. The most common colonoscopy indications in childhood are; lower gastrointestinal bleeding, chronic diarrhea and chronic abdominal pain. We aimed to contribute to the literature by retrospectively examining the characteristics of pediatric patients who underwent colonoscopy in our clinic.
Material and Methods: Pediatric patients who underwent colonoscopy by a single pediatric gastroenterologist during the 6-year period between August 2017 and August 2022 were included. The patients were divided into four different age groups and their characteristics were compared. Additionally, differences were investigated in colonoscopies performed in two different periods.
Results: In the study, 614 colonoscopies were performed in 551 patients. The average age of the patients was 12.3±4.7, 51.9% were female and 48.1% were male. 2.2% under two years of age; 8.3% between 2-6 years old; while the rate of patients aged 6-12 was 22.7%, the rate of patients over 12 years of age was 66.8%, 40.5% of the patients had one complaint, 30.7% had two complaints, 28.8% had three or more complaints. The most common complaint was chronic diarrhea in 31% (n=171), rectal bleeding in 16.7% (n=92), and bloody mucus stools in 13% (n=71). Main colonoscopy indications: suspicion of inflammatory bowel disease (n=406, 73.7%), colorectal polyp investigation (n=72, 13.1%), malignancy screening (n=35, 6.4%), lower gastrointestinal tract bleeding (n=35, 6.4%). The most common colonoscopy findings were inflammatory bowel disease with 32.3% (n=178), colorectal polyp with 4.2% (n=23), and solitary rectal ulcer with 3.3% (n=18). 49.7% of colonoscopies were normal and 4.2% were dirty. The ileum intubation success rate in colonoscopy was 92.4%. There were no complications.
Conclusion: In pediatric patients presenting with gastrointestinal system signs and symptoms, performing biopsy and colonoscopy more actively, safely and effectively will provide early accurate diagnosis and treatment of many diseases, especially inflammatory bowel disease.

Published: December 2024

Amaç: Koroner arter çapları akut koroner sendromlar sırasında kullanılacak stent çapını belirlemek için çok önemlidir. Özellikle osteal lezyonlarda referans alınacak başka bir damar olmaması sorun oluşturmaktadır. Çalışmamızın amacı normal koroner arter yapısına sahip koroner arter hastalığı (obstrüktif veya ektatik koroner arter) olmayan hastalarda, koroner arter çaplarıyla hastaların antropometrik ölçümlerinin korelasyonunu incelemektir.
Gereç ve Yöntemler: Retrospektif olarak yürütülen bu çalışmaya koroner anjiografi yapılmış ve anjiografik olarak plak ve ektazi izlenmeyen 102 hasta dahil edildi. Hastalar el bilek çevrelerine göre üç gruba ayrıldı. Hastaların klinik ve anjiografik görüntüleri hastane otomasyon sisteminden değerlendirildi.
Bulgular: Bilek çevresi grupları arasındaki değerlendirmede gruplar arasında istatistiksel olarak anlamlı bir fark olduğu izlenmiştir. Sol ana koroner arter, sirkumfleks arter, sol ön inen arter için bilek çevresi çapları ile pozitif korelasyon izlenmiştir. Bilek çevresi ile sol ana koroner çapı arasında r=0.390, p<0.001, sol ön inen arter çapı arasında r=0.244, p=0.013, sirkumfleks arter çapı arasında r=0.303, p=0.002 ve sağ ana koroner çapı arasında r=0.223, p=0.024 pozitif korelasyon olduğu görülmüştür (Spearman, p<0.05). Çalışmamızda elde ettiğimiz sonuçlara göre bilek çevresi 15.5 üstünde olan hastaların %80 inin sol ana koroner arter arter çapı 4.0 mm üzerindedir.
Sonuç: Bu çalışmada özellikle, bilek çevresi ile sol ana koroner arter çapı arasında istatistiksel açıdan önemli pozitif korelasyon bulunmuştur. Sol ana koroner arter, osteal lezyonlarında intravasküler ultrasonografi kullanılamayan durumlarda kullanılacak stent boyutunun belirlenmesinde bu pozitif korelasyonun önemli bir özellik olabileceği düşünülmektedir. Daha geniş kapsamlı çalışmalarla bilek çevresi ve sol ana koroner arter çapı arasında bir formülasyon elde edilebilir

Published: December 2024

Antimicrobial peptides, renowned for their diverse biological properties, hold significant potential as sources for developing new pharmaceutical agents and food preservatives. A recent study investigating various derivatives of the natural peptide Mastoparan C revealed that the peptide MPC-A5K,A8K exhibited strong antimicrobial activity with low toxicity to human red blood cells. In this study, MPC-A5K,A8K’s antimicrobial effectiveness was compared to several antibiotics, and its preservative potential in oral formulations was preliminarily evaluated. The peptide MPC-A5K,A8K was synthesized through solid-phase peptide synthesis, with alanine residues at positions 5 and 8 in Mastoparan C replaced by lysine. The product achieved a purity of 98.1%, with an overall synthesis efficiency of 31.2%. This MPC-A5K,A8K derivative demonstrated broad-spectrum antimicrobial activity, including Gram-positive and Gram-negative bacteria as well as the fungus Candida albicans, with minimum inhibitory concentrations (MICs) ranging from 4 to 64 μM. In preliminary preservative efficacy tests, incorporating 10 ppm of MPC-A5K,A8K in formulations allowed for a reduction in sodium benzoate and potassium sorbate concentrations to 0.1% each while maintaining effective preservative properties. These promising findings lay a foundation for further research into the potential applications of MPC-A5K,A8K as a dual antimicrobial and preservative agents.

Many academics have recently concentrated on applying integral transforms to solve challenging problems in economics, biology, engineering, and medicine. In this paper, the Kharrat-Toma transform is used to issues related to population growth and decay problem. These are important topics in the fields of finance, physics, chemistry, biology, and society. Many applications show the value and efficacy the Kharrat-Toma transform is used to analyze concerns with population growth and decrease. The findings demonstrate the usefulness of the Kharrat-Toma transform in resolving problems associated with population growth and deterioration. In population growth and decay problems there is a differential equation model in mathematics that can be analyzed by the Kharat-Toma transform. We have shown its analysis and applications in this article.
Global Climate Effect from Space Debris Reentry: Engineering and Policy Implications
Authors: Jain Asha K. , Hastings Daniel E.
Published: December 2024

Space objects are routinely reentered into Earth’s atmosphere for disposal. During reentry, space objects demise and produce ablation by-products, including alumina ([Formula: see text]) particles that can interact with Earth’s radiative balance, and possibly influence climate change. In this work, we model a future reentry scenario with [Formula: see text] of alumina entering into the South Pacific from controlled reentries to estimate the implications of a hypothetical policy that requires all reentries to demise over this region. We find that reentry alumina particles remain aloft in the atmosphere for 714 days, generating a direct radiative cooling effect of [Formula: see text] at the top of the atmosphere and [Formula: see text] at the tropopause. These South Pacific reentries create a concentration of particles in the southern stratosphere, leading to asymmetrical radiative forcing. When compared to aviation, the direct radiative forcing from a single reentry is greater in magnitude than a single commercial airliner flight, but reentries as a whole produce less radiative forcing per dollar of industry revenue than commercial aviation. These results support policies that encourage satellite design for demise and reentry as a form of decommissioning but warn against limiting reentry to the South Pacific only.
A Refined Model to Predict Boundary of Instability of Axial Compressors
Authors: Wang Xuegao , Tu Baofeng , Hu Jun , Zheng Xinqian
Published: December 2024

A quantitative model to predict the boundary of instability of axial compressors based on their maximum loading capability is proposed in this paper, which is an improved version of the classic method of stalling pressure rise. The original model correlates the maximum pressure rise of a compressor to a characteristic geometric parameter, which is an analogue of the normalized length of diffusion in two-dimensional diffusers. However, the influence of the aspect ratio of the passage is overlooked in this analogy, which leads to significant discrepancies in its predictions for compressors, especially those with varying blade aspect ratios. Our model contains two improvements to address this issue. The first involves refining in the definition of the normalized length of diffusion, whereas the second introduces a supplementary correction factor for the aspect ratio of the blades. Nearly 20 low-speed compressor configurations, with variations in solidity, aspect ratio, tip clearance, and axial spacing, were tested to develop the proposed model. It can reduce error in the predicted stalling static pressure rise from 10% to 5%. Experimental data robustly verify the accuracy of our model, making it a more reliable predictive tool of instability boundary in the preliminary design of axial compressors.

Published: December 2024

Energy-maneuverability diagrams are an important tool that operational pilots use to understand helicopter maneuver performance through excess available power across a wide range of conditions. These representations are based upon a number of assumptions that have not been rigorously investigated for helicopter applications. The present work reports the results of an investigation into the theory and application of helicopter maneuverability through simulation and flight test. The computational portion of the work focused on a systematic investigation into some of the key simplifying assumptions that are commonly applied in the creation of energy-maneuverability diagrams using two rotor wake aerodynamic modeling methods. The flight test portion of the work provided important operational context for understanding the practical application of the simulation results. The study illustrated that the fundamental assumption employed in estimating maneuver power requirements for energy-maneuverability representations appears to be reasonable in conditions of the greatest practical relevance; however, another key assumption that is invoked to convert excess power into climb performance would likely lead to overestimating the vehicle capability in important operational conditions. Additionally, the flight test data demonstrated that, at high angles of bank, energy-maneuverability results should be considered for trending information rather than for detailed climb performance values.

Published: December 2024

To study the antiflammability of composite material panels, assemblies, or components, certification standards require significant [Formula: see text] samples to withstand a kerosene flame for 15-min tests. To better analyze thermophysical phenomena involved in a flame exposition of composite-based samples, a laboratory test bench composed of a small-scale air–kerosene burner has been developed. The current work presents the development of a representative kerosene burner in terms of aerothermal stress generated by determining the right settings for the flame parameters and by comparing the fire-induced degradation process of several four-ply epoxy-composite samples. Two laboratory-scale tests are made and compared to a large-scale one made on a standardized fire test bench.
Analysis of the thermodynamic efficiency of a theoretical multi-stage compressor with the combined use of adiabatic, isothermal and subisothermal compression processes
Authors:   OJSC «Sibneftetransproekt», Yusha V. L.
Published: December 2024

A thermodynamic analysis of compression processes with intensive heat removal is presented under
the assumption that it can be realized with a polytropic index less than 1. A terminological classification
of polytropic processes is proposed, including the concept of a subisothermal process. A method has
been developed for determining the polytropic index of a subisothermal process under theoretical
combined multi-stage compression, as well as methods for comparative assessment of the energy
efficiency of various options for theoretical combined multi-stage compression and the thermal load on
heat exchange equipment. A comparative thermodynamic analysis of various options for theoretical multistage compression with the combined use of adiabatic, isothermal and subisothermal stages has been
performed. The results obtained suggest that, theoretically, from the point of view of thermodynamic
efficiency criteria, combined multistage compression is preferable to multistage adiabatic compression.
The prospects for the practical use of subisothermal stages as part of multi-stage compressor units are
determined by the possibilities of their constructive implementation.

Published: December 2024

The study examines short-diffuser adsorption filters designed to remove pollutants from vapor-gas
mixtures. The design process of the flow path of such filters is considered, which includes the stages of
determining the parameters of the adsorbent layer, modeling gas-dynamic processes using numerical
methods in the ANSYS CFX program and analyzing the results. The numerical studies cover various
options for backfilling the adsorbent, including layer profiling and the use of adsorbent with different
porosity, which allows us to assess the impact of these factors on the aerodynamic resistance and overall
efficiency of the filter. A design algorithm is also proposed that ensures optimal compliance between
the adsorbent layer thickness and the local flow velocity, which helps to increase the protective action
time of the filter and improve the quality of cleaning.

Published: December 2024

Soil is not only the most important component of the ecosystem, providing specific habitat conditions for bacteria, fungi, actinomycetes, algae and other microorganisms that make up the soil microflora, but also a means of crop production. It is well known that modern agricultural production would be impossible without the use of chemical pesticides, which form the basis of modern plant protection. At present, excessive use of fertilizers and pesticides not only pollutes the soil, but also affects its quality and reduces the biodiversity of the soil profile. The study of the interaction between pesticides and soil microflora is necessary due to the important role of microorgan-isms in the development of fertility and detoxification of soil from xenobiotics. An important problem is the replacement of toxic pesticides with new types of preparations that are less polluting to the soil and are able to degrade under the influence of microorganisms.

Published: December 2024

Rapeseed, as one of the crops related to renewable plant resources, can be considered a strategic "culture of the future" due to its high plasticity in relation to growing conditions, however, despite its unpretentiousness, it requires certain care during the growing season to ensure more stable yields with rapid maturation (30-40 kg/ha or more) and the content of a large amount of oil in the seeds (40-52 %) and crude protein (21-34 %). Rapeseed oil, obtained from modern varieties and containing 61-66 % oleic acid and 18-20 % linoleic acid in its composition with an optimal content of up to 70 % oleic acid and up to 28 % linoleic acid for edible vegetable oil, is considered one of the best vegetable oils. A significant increase in demand for rapeseed arose when obtaining food grade varieties (type "00") with a minimum content of erucic acid in its oil, which in refined edible oils of the highest grade should not exceed 2 % of the total fatty acids. In the Russian Federation, it is possible to produce rapeseed oil with a regulated composition of fatty acids. This makes it a sought-after export product that is widely used in various industries. There are also prospects for expanding the acreage for rapeseed, and increasing the seed productivity of the crop, taking into account environmental factors, will increase the production of rapeseed both for the domestic market and for export.

Published: December 2024

Objectives

Adnexal lesions are often detected incidentally during infertility evaluation. However, limited data exists on the pathological profile of adnexal lesions detected, particularly in infertile women. In this study, we aim to assess the histopathological profile of adnexal masses in infertile women.

Material and Methods

Retrospective analysis of infertile women with an adnexal mass undergoing surgery between 1 January 2018 and 30 May 2024 was done. Details pertaining to demographic profile, ultrasonography, biochemical markers, surgical findings and histopathology were retrieved. Histopathological profile was studied as per the Royal College of Obstetricians and Gynaecology (RCOG) histopathological classification. Statistical analysis was done using the SPSS Statistics software (v27.0).

Results

Of the 5170 patients screened, 62 patients eligible for study criteria were included. The mean age (standard deviation [SD]) was 33.1 (4.6) years, with 85.5% (53/62) of patients being nulliparous. Ultrasonographic evaluation revealed bilateral adnexal lesions in 25.8% (16/62) patients. Most patients underwent laparoscopic surgery (91.9%, 57/62). CA-125 was available for 34 patients and was raised in 58.9% (20/34) patients. The histopathological profile revealed 93.6% (58/62) of patients having benign lesions of ovarian origin, while 3.2% (2/62) had benign lesions of non-ovarian origin. Endometriosis (66.1%, 41/62) and mature teratoma (12.9%, 8/62) were the most common benign lesions. Two patients (3.2%) with malignancy had borderline mucinous tumours.

Conclusion

Benign ovarian lesions form the most common adnexal masses in women of reproductive age group who present with infertility; however, malignancy is not uncommon. Endometriosis and mature teratoma appeared to be the most common benign lesions.

Published: December 2024

Objectives:

Among the non-communicable disease, the cardiovascular disease is major cause of mortality worldwide. The risk factors include the hypertension, diabetes mellitus increasing age and gender, and dyslipidemia. Recently, much attention has been paid to impact of weight in determining the cardiovascular events and it’s role in development of chronic disease. Studies have been published for fetal origin for adult disease; one among them is barker’s hypothesis. Furthermore, epidemiological study proposes decremental effects of birth weight outside the normal range. Our study focuses on significance of birth weight, weight dynamism from birth to adulthood for correlation with heart failure (HF) in adults.

Materials and Methods:

Imaging studies were done with echocardiography (ECHO) of 2.5–3.5 Mhz transducers. Patients were grouped as Group A and B. Group A is asymptomatic, healthy population. Group B patients have failure signs and symptoms. Both group undergone to 2D ECHO, necessary tests, and body mass index measured.

Results:

In our study, we collected data from 100 subjects. Out of 50 patients in case, group age of patient ranges from 50 to 60 years. Among the control group, age of patients ranges from 50 to 60 years. Mean age of patient in case group is 58.4 ± 3.36 year. Mean age of patients in Group A is 56.6 ± 3.02 years. Birth weight among the patients with HF ranges from 1.5 to 3.5 kg. Total number of patients having low birth weight (LBW) is 44 among case group. None of patients were having LBW in control group and was statistically significant (P < 0.001). Thus indicating, there is higher incidence of HF in patients having LBW. Mean birth weight among patients with HF was 2.14 ± 0.267 kg and among control group was 3.01 ± 0.276 kg. Incidence of HF was more among women than men group.

Conclusion:

The LBW associated HF and has inverse relationship with cardiovascular function; also, adult obese population have increased risk of HF. similarly, severe left ventricular dysfunction had high present weight and women had high risk of HF compared to men group.

Dramaturgi Identitas Virtual Pemain Role-Play: Studi Netnografi Penggemar K-Pop pada Grup Telegram RVS
Authors: Chofsho Mardiyana , Hidayat Medhy Aginta
Published: December 2024

Artikel ini mengkaji fenomena dramaturgi para pemain role-play yang melahirkan dualisme identitas, yakni identitas virtual di media sosial dan identitas nyata dalam kehidupan yang sebenarnya. Korean Wave merupakan gejala globalisasi kebudayaan yang berasal dari Korea Selatan. Aktivitas baru yang dimunculkan berkat adanya gelombang K-Pop adalah Role-Play. Role-Play adalah permainan peran yang dilakukan di dunia maya oleh sekelompok penggemar artis K-Pop. Penelitian ini menggunakan metode kualitatif dengan menggunakan pendekatan netnografi simbolis. Pengumpulan data menggunakan teknik observasi, wawancara-mendalam (kepada 10 informan), dan dokumentasi. Teori yang digunakan dalam penelitian ini adalah teori dramaturgi dari Erving Goffman. Hasil penelitian ini menunjukkan bahwa para pemain role-play memiliki identitas ganda (dualisme identitas), yakni identitas virtual palsu di media sosial, dan identitas asli dalam kehidupan sehari-hari. Para pemain role-play di Telegram melakukan praktik dramaturgi dengan cara berkamuflase dan menutup identitas bahwa mereka adalah pemain role-play, terutama dihadapan orang-orang yang ada di kehidupan nyata. Penelitian ini juga menemukan bahwa para pemain role-play memainkan permainan tersebut dikarenakan mereka tidak bisa mendapatkan apa yang mereka inginkan di dalam kehidupan nyata. Para pemain role-play sengaja melakukan kamuflase dikarenakan takut jika dianggap aneh karena menggemari dunia K-Pop, karena tidak semua orang dapat menerima budaya baru yang berasal dari luar.

The Alterozoom hardware and software system is built as a system of personal information systems interacting via a cloud service. Personal information systems are a set of tools that allow the user to organise a personal information space, which along with multimedia documents, organised into knowledge bases, documents include interfaces of smart things, which are combined into complex personal Internet of Things systems. Personal information systems can be used for educational purposes in the form of personal learning environments which contain both virtual objects (user documents) and images of real objects in an integrated form. Integration of virtual and real objects allows organizing educational materials that provide a visual (interactive) representation of the studied subjects of the natural science cycle in conjunction with the study of information technology, which makes a meaningful representation of real world objects and processes possible.

Экспертиза электронных образовательных ресурсов с помощью PN-метода
Authors: Корчажкина О.М.
Published: December 2024

В статье обсуждается проблема экспертизы электронных образовательных ресурсов (ЭОР), представляющих собой сложные информационно-педагогические системы, с точки зрения поиска и разрешения противоречий между их компонентами. В качестве инструмента поиска противоречий предлагается использовать PN-метод, который берёт своё начало в теории решения изобретательских задач и является дальнейшим развитием на системной основе наиболее известной её части, касающейся работы с противоречиями в инновационных решениях. Выбор PN-метода обусловлен логической строгостью и большим потенциалом решения творческих задач, чем качественно отличается от ранее известных подходов, применяемых к схожим проблемным ситуациям, но опирающихся на иные приёмы выявления и разрешения узкого круга противоречий Обосновывается процедура адаптации терминов «противоречие в пространстве» и «противоречие во времени» применительно к экспертизе ЭОР, описываются алгоритмы поиска упомянутых противоречий в информационно-педагогических системах на основе PN-метода. Рассмотрение противоречий производится с учётом полного дидактического цикла усвоения учебного материала, представленного в ЭОР, а также всех значимых компонентов процесса обучения и причинно-следственных связей между ними. Предлагаются инструменты разрешения противоречий с помощью способов, основанных на процедуре контраргументации и технологии обучения по прецедентам, а также приводятся примеры их практического использования.

The article focuses on the problem of expert examination of electronic educational resources (EER), which present complex information and pedagogical systems as they are, from a viewpoint of searching and resolving inconsistencies between their components. To look for contradictions we propose the PN-method as a tool, which originates in the theory of solving inventive problems and is a further systemic development of its most famous part regarding a deal with inconsistency in innovative solutions. The choice of the PN-method is made due to its logical rigor and great potential for solving creative problems. These factors qualitatively distinguish the method from previously known approaches applied to similar problem situations that are based on other methods of identifying and resolving a narrow circle of inconsistency. The adaptation of the terms “contradiction in space” and “a contradiction in time” to expert examination of EER is explained. We also describe algorithms of searching for inconsistencies based on the PN-method in information and pedagogical systems, consider inconsistencies in the complete didactic cycle of mastering learning material presented in the EER, taking into account all the significant components of the teaching process and cause-effect relationships between them. The article exhibits tools for resolving inconsistency using methods based on the counterargument procedure and the technology of training on precedents, as well as examples of their use in practice.
The Improved Algorithm for Calculation of the Contextual Words Meaning in the Text
Authors: Dorenskaya E.A. , Semenov Y.A.
Published: December 2024

Some modifications of the algorithm for context calculation, published in [1], are considered. A new solution for word and document context calculation is proposed. To improve a context determination it is proposed to take into consideration distances between words W1 and W2. This approach is especially important, when W2 number is >1. The results of investigations of these two formulas are presented. For efficiency comparison of these formulas calculation has been made for 100 texts. There were built distributions for C average and dispersion, which were compared with model data from [1]. The weight function has been optimized. The versions comparison was made according to the value of s/Сaver. The C dispersion was calculated for all version of the weight function. Dispersion of C appeared to be rather big because of great variation of text size, number W2 and W3, as well as wide distribution of words in the text. There is an example of L distribution for W2=”компьютер”.

Рассмотрены некоторые модификации алгоритма определения контекста, опубликованного ранее [1]. Предложена усовершенствованная формула для вычисления контекста слова и документа. Для более точного расчёта контекстного значения предложено учитывать расстояния между словами W1 и W2. Такой подход важен при наличии числа W2 >1. Приводятся результаты исследования работы этих 2-х формул. Для сравнения эффективности формул были проведены расчеты для 100 текстов. По данным расчётов построены распределения, которые были сравнены с моделью, описанной в статье [1]. Проведен оптимальный выбор весовой функции , Сравнение вариантов проводилось по значениям отношений s/Ссред, Для всех вариантов формулы, весовой функции и ширины площадки была рассчитана дисперсия С. Она оказалась довольно большой за счёт разного размера текстов, количества слов W2 и W3, а также их распределения по тексту. Предоставлен пример распределения расстояний между словами W2-W3 в файле для слова W2 “компьютер”.
Автоматизация исследования динамики 3D-моделей оптико-механических систем с использованием среды Matlab
Authors: Понятский В.М. , Романов А.В.
Published: December 2024

При разработке сложной оптической техники трудоемкой задачей является выбор шагового двигателя. Разработана методика по оценке мощности шагового двигателя, основанная на использовании САПР SOLIDWORKS и Matlab/Simulink. Для механизма панкратического объектива разработана динамическая модель, позволяющая определить необходимый крутящий момент, развиваемый двигателем, с учетом воздействия пружин, сложного профиля и программного изменения угла поворота кулачкового механизма. Данная методика включает в себя несколько этапов. Сутью первого этапа является получение из 3D-модели САПР SolidWorks модели в среде MatLab. Сначала 3D-модель экспортируется в xml-файл данных с помощью транслятора Simscape Multibody Link. После того как произведен экспорт в xml-файл, модель импортируется непосредственно в Simscape Multibody Model. При трансляции, телам модели Simulink передаются соответствующие массо-инерционные характеристики компонентов сборки SolidWorks, а также сопряжения между телами 3D-модели SolidWorks, которые преобразуются в степени свободы динамических тел Simulink. Фактически при трансляции осуществляется построение динамической модели механизма. Для обеспечения визуализации модели Simulink геометрия элементов сборки SolidWorks передается с помощью транслируемых stl-файлов. Вторым этапом является доработка полученной динамической модели.

In developing the complex optical techniques, the choice of a stepped motor is an arduous task. A methodology for estimating the power of the stepped motor has been developed, based on the use of CAD SOLIDWORKS and Matlab/Simulink. A dynamic model has been developed for a pancratic lens mechanism, which makes it possible to determine the required torque developed by the engine, taking into account the effect of springs, a complex profile and programmed change in the angle of rotation of the cam gear. This technique includes several stages. The essence of the first stage is to transform a 3D CAD SolidWorks model into a model in the MatLab environment. First, the 3D model is exported to an xml data file using the Simscape Multibody Link translator. After exporting to an xml file, the model is imported directly into the Simscape Multibody Model. When translating Simulink bodies receive the corresponding mass-inertial characteristics of SolidWorks assembly components, as well as mates between the bodies of the SolidWorks 3D model, which are converted to the degrees of freedom of dynamic Simulink bodies. In fact, when translating a dynamic model of the mechanism is constructed. To provide visualization of the Simulink model, the geometry of the SolidWorks assembly elements is transferred using translated stl files. The second step was to refine the resulting dynamic model.
