(2017) V. Makarenko, O. Olshevska, Yu. Kornienko
Developing a proper system architecture is a critical factor for the success of the project. After the analysisphase is complete, system design begins. For an effective solution developing it is very important that it will be flexible andscalable. During the system design, its component composition and development tools are determined. The system designphase is an opportunity to maximize the speed and effectiveness of subsequent development.There are quite a lot of architectural approaches for building systems. Despite their small differences, they have much incommon. They all define ways of splitting the application into separate layers. At the same time, in each system, at least, thereis a layer containing the business logic of the application, a layer of data interaction and a layer for displaying data.The "Clean Architecture" approach has been analyzed and adapted to the communication application for mechatronicsrobot laboratory developing. This approach allows to solve all the problems while building the application architecture: itmakes the code modular, tested and easily readable, and also positively affects the quality of development.New architectural components which was introduced by Google in 2017 was considered. The analysis showed that theArchitecture Components fit well into the concept and will interact with the "Clean Architecture" approach. Dagger 2framework was applied for a complete abstraction and simplify testing. Also, it is planned to implement the RxJava library.

AUTOMATIC CONTROL OF PARAMETERS OF A NON-STATIONARY OBJECT WITH CROSS LINKS
(2018) A. Pavlov
Many objects automatic control unsteady. This is manifested in the change of their parameters. Therefore, periodically adjust the required parameters of the controller. This work is usually carried out rarely. For a long time, regulators are working with is not the optimal settings. The consequence of this is the low quality of many industrial control systems. The solution problem is the use of robust controllers. ACS with traditional PI and PID controllers have a very limited range of normal operation modes due to the appearance of parametric disturbances due to changes in the characteristics of the automated unit and changes in the load on it. The situation is different when using in the architecture of artificial neural network controllers. It is known that when training a neural network, the adaptation procedure is often used. This makes it possible to greatly expand the area of normal operating modes of ACS with neural automatic regulators in comparison with traditional linear regulators. It is also possible to significantly improve the quality of control (especially for a non-stationary multidimensional object), provided that when designing the ACS at the stage of its simulation in the model of the regulatory object model, an adequate simulation model of the executive device. It is also possible to significantly improve the quality of control (especially for a non-stationary multidimensional regulatory object model, an adequate simulation model of the executive device. Especially actual implementation of all these requirements in the application of electric actuators. This article fully complies with these requirements. This is what makes it possible to provide a guaranteed quality of control in non-stationary ACS with multidimensional objects and cross-links between control channels. The possibility of using a known hybrid automatic regulator to stabilize the parameters of a two-channel non-stationary object with two cross-linked. A simulation control system under the action of the object coordinate and parametric perturbations. The simulation showed that the quality control is not reduced

(2020) Л. С. Жуковецька, Н. В. Слушна
Технології просторової візуалізації і симуляції роботи технологічного обладнання набули особливої актуальності завдяки тому, що забезпечують істотно більш наочний спосіб розгляду проектованого об'єкта. Віртуальні прототипи, в ролі яких виступають 3D моделі, дозволяють проаналізувати роботу обладнання перед прийняттям проектних рішень. При вивченні та дослідженні моделей істотну допомогу надає анімація – тобто відтворення і демонстрація моделі в процесі її формування або зміни.У даній статті описується моделювання потоку рідини в замкнутому контурі на основі твердотільної просторової моделі елементів мультизональної системи кондиціонування. В якості системи просторового моделювання та аналізу використаний продукт компанії SolidWorks Inc. Для моделювання потоку використовується інструмент Flow Simulation, який включений в SolidWorks і реалізує методи обчислювальної гідродинаміки. При підготовці до дослідження була створена просторова модель і сформована розрахункова область. Суть формування розрахункової області зводиться до виділення на моделі замкнутого контуру, що відповідає умовам наявності стінок зіткнення і обмеженості вхідних і вихідних отворів. Після чого задача аналізу протікання рідини по замкнутому контуру зводиться до вирішення стаціонарної задачі внутрішнього типу. В цьому випадку замкнута порожнина – це і є рідинний простір, а заглушки на кінцях отворів трубопроводу є тими елементами, які завершують формування системи "рідина-тіло". Для такої системи вже можливе проведення гідрогазодинамічного аналізу за допомогою Flow Simulation. Використання комплексу сучасних програмних засобів забезпечило візуальну оцінку картини перебігу холодоагенту по трубопроводу мультизональної системи кондиціонування, необхідну для визначення проблемних місць.
Classification mechanisms for digitalized information in web application development, taking into account cloud server deployment trends
(2022) Zh. Tyturenko, I. Zinchenko, O. Olshevska, A. Volkova
With the transition from natural to virtual communication, there are new technologies for presenting information, the perception of which depends on its presentation by modern multimedia. Visual perception plays an important role in everyday life, helping in learning and communicating with other people. Behind the most effective perception is a complex process of understanding the information obtained. Visual perception of information includes the processes of seeing and reading. Building assumptions on what we see, we rely on expectations, beliefs, past knowledge and previous experience. Reading is a complex activity that involves both the process of perception and thought. At the very beginning of the formation of reading, understanding is not common, but only after perception, as the development and automation of reading skills, understanding begins to outpace the process of perception, manifested in the emergence of semantic assumptions, guessing meaning within words. Perception of visual image is accompanied by the actualization of its auditory-motor image, without which it is impossible to recognize. Reading is accompanied by inner speech. The same information can be understood by different people with different degrees of depth, which entails the existence of factors that affect the process of perception and understanding of texts. Such factors can be divided into the following groups: characteristics of the individual who acts as a subject of perception and understanding; parameters of the text and the reality that is reflected in this text; features of the situation in which the process of perception and understanding takes place. Text in a virtual environment, ie media information - is more accurately and quickly perceived by a person and it depends on various factors influencing perception, as well as the type and method of presenting information. The purpose of the study is to analyze the perception of digitalized information, the formation of recommendations for professionals with UI / UX, which will be further formed into a prototype of a possible web directory. The aim is also to develop a possible tool model that can be used not only by the above specialists, but also by SMM-managers, business analysts and others. The methods of research were chosen analysis - the study of individual parts of the objects of study, comparing different approaches or their individual components to obtain a holistic picture of the subject area.
