3D-моделювання персонажів з анімацією для ігрових проектів. Частина 1
(2022) В. С. Вилков, С. В. Болтач, П. Б. Ломовцев
Технології 3d графіки проникли в багато сфер людської діяльності, і приносять колосальний прибуток. Так у сфері науки 3D-графіка використовується в основному для проектування технічних виробів. Сучасні технології дозволяють створити візуалізацію проектованого об'єкта, максимально наближеного до реального пристрою, оцінити його наочно. Тривимірна модель майбутнього механізму прискорює і полегшує роботу інженера-конструктора, позбавляючи його від процесу креслення. Графіка у сфері реклами та маркетингу використовується майже завжди. Все частіше маркетологи використовують 3D-візуалізацію об'єктів, створюючи анімаційні рекламні ролики. Зйомки в реальних умовах не дають такої привабливої картинки, як із застосуванням анімації. 3D-зображення інтер'єру або будівлі з використанням комп'ютерних програм зацікавилися порівняно недавно, так як раніше для цього виготовляли макети з картону або спеціальних матеріалів. Сьогодні 3D-візуалізація будинку - важливий етап перед початком будівельних робіт. Дана технологія дозволяє подивитися на готовий об'єкт і внести зміни при необхідності. Звичайно у кінематографі і ігровій індустрії 3D-графіка прижилася і вкоренилася назавжди. Сучасній людині важко уявити улюблену гру без тривимірних персонажів, а черговий фільм - без 3D-графіки.

(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.

(2021) Аlfiia Antonova, Svitlana Bartkova
The article discusses cloud computing and their impact on the field of software development, and analyzes several issues of developers that can be solved using the online IDE. Usage of cloud computing in the enterprise is not new, and it is not difficult in terms of implementation. That is why it is gaining popularity. First, due to the large number of technologies that allow you to optimize internal processes. Secondly, due to the large number of giant companies and small businesses that use these technologies. Cloud computing is very interesting in financial terms. After all, they allow not spending money on building and supporting the infrastructure. One can also not worry about risks, such as, for example, equipment that affects the system, weather conditions, and so on. It takes on all these moments. Evolving of architectural solutions also increases the impact on cloud technology. A service-oriented approach to software development is becoming increasingly popular. It is less and less possible to see the usual thin client and a single server-monolith. Clients are becoming more complex, attracting part of the business logic, servers are divided into parts, each of which is responsible for a particular part of the subject area, and in some cases may not know about the existence of others. The IDE, which requires developers for programming, also has analogs on the web platform. The online IDE has its advantages for solving some tasks and has become increasingly popular lately. Users of the online IDE can create, run, and customize software that works with a simple browser. The main goal of this study is to determine the main advantages of cloud technologies in the application development process, analyze the segment of online IDE. Based on these data to identify the main situations that determine their use, predict further development, and identify principles and technologies used in this area.

(2019) O. Sakaliuk, F. Trishyn
The organization of education for persons who are studying is carried out in accordance with the coursestimetabling. Courses timetabling should provide an effective implementation of the curriculum in full.The problem of creating the courses timetabling has been given sufficient attention during the last decades. But even today,the process of creating the courses timetabling requires a fairly large part of human control. The typical problem of creatingthe courses timetabling is to plan a set of meetings between teachers and students over a period of time that requires someresources and should meet some additional requirements. Significant requirements in scheduling are those in which theteacher, student, or audience is not used more than once at the one-time interval. Creating the courses timetabling ininstitutions of higher education is carried out every semester. Preparing the timetabling of the courses is a labor-intensive,tedious process that requires a significant amount of human resources and time.In this scientific article, an analysis of process creation of the courses timetabling is carried out.

ANALYSIS OF THE ENERGY SYSTEM BALANCE EFFICIENCY PROVIDED WITH THE DIFFERENT GROUPS OF GENERATING PLANTS
(2018) O. Maksymovа, M. Maksymov, V. Silina, A. Orischenko
Currently methods of efficiency analysis are being developed and applied, based on optimization tasks for various types and modes. Usually, the optimization criterion for these objectives is efficiency that can be calculated in various ways, for which there is no concurrent views. The target function based on minimization of given cost that allows comparing options with the same useful effect is used to search for the best indicators of power plants operated within the system. Marginal costs on the amount of difference in the useful effect are introduced to the target function in case of various useful effects. The criterion of selecting the best power plant from an economic point of view is the difference between the reduced costs of the considered and the basic options, but this approach does not allow using the results for long-term projections. Such approach depends on the situation and does not reflect the real costs. The value of the target function to optimize the effectiveness of the technical-economic method is not "marginal" and does not allow assessing the impact of various processes on the overall option efficiency. Therefore, the development of the efficiency criterion that considers the changing needs of the energy system is relevant for analyzing the power plant.

(2023) Sajeewani Tharanga, Koliya Pulasinghe, Faiz Marikar
. Tea is the most favorable beverage in the world after the pure water. Professional tea tasters categorize thequality of the tea in subjective manner by assessing the several parameters. The flavor, aroma and color of tea are themost important and considered parameters when professional tea tasters categorize and evaluate tea. The value of abovementioned parameters depends on the chemical composition of the tea. Basically, flavanols are major compounds whichaffect the quality of the tea. Therefore, it is possible to identify a correlation between flavanols composition of tea andprofessional tea taster’s valuation. The main purpose of this article is identifying above correlation and according to thatcorrelation design and implements “Artificial Neural Network (ANN) based Intelligent Tea Taster” to automate manualtea tasting process. This review is focused on training an artificial neural network according to identified correlationbetween flavanols composition and tea taster’s valuation and based on that trained artificial neural network After goingthrough successful training iterations and evaluations, a computer-based solution can be designed and implemented todefine the quality of tea according to its flavanols compound. The results show good correlation of estimated values oftheaflavins and thearubigins with the actual concentrations obtained by the system when we tested at laboratory. Thereview is based on ANN base Intelligent Tea Taster will automate the tea tasting process while improving efficiency,effectiveness and accuracy of the tea tasting process.

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

(2017) A. I. 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. Explores the possibility of increasing the survivability of automatic control systems by expanding the area of their normal work. This is achieved by using an artificial neural network simple structure. The method is based on the cooperative effect of neural structures. In this block diagram of the controller is very simple. Such control effectively compensates the coordinate perturbations if they act on the control channel.

(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.
