Публікація Automated modeling of shaft leading elements in the rear axle gear(SPC, 2018) Matarneh, Rami; Sotnik, S.; Belova, N.; Lyashenko, V.The aim of this work is to automate the design process of the "shaft leading" of the rear axle gear in order to reduce the time and effort. All the technical requirements for the design process are given and SolidWorks development medium is selected. A 3D model was developed and steel material 40X was added and its parameters were specified. A finite element analysis of the created design performed under the action of the torque transmission force.Публікація Contrasting as a Method of Processing Medical Images in the Study of Fatty Liver Disease(Journal of Universal Science Research, 2023) Boboyorov Sardor Uchqun o‘g‘li; Tanianskyi, O.; Belova, N.; Lyashenko, V.Diagnosis of diseases is one of the priorities in the development of modern medicine. Various data sources can be used for these purposes. Among such sources, medical images should be singled out, which reflect the microcosm of the phenomena under study. The study of medical images is possible based on the use of various image processing techniques. These techniques allow you to prepare the i nput image for research and perform the necessary analysis. One of the image processing techniques is contrasting the input image. This procedure makes it possible to improve the quality of perception of a medical image, to make a preliminary stage of its processing. On the example of images that contain foci of fatty liver lesions, the procedure for contrasting the input image is considered. Examples for real medical images are given, the possibility and expediency of using the contrasting procedure are discussed.Публікація Cyber-social computing of relationship(Kharkiv National University of Radio Electronics, 2016) Abdullayev Vugar Hacimahmud; Hahanov, V.; Soklakova, T.; Belova, N.Публікація Digital image of a blood smear as an object for research(2023) Boboyorov Sardor Uchqun o‘g‘li; Belova, N.; Lyashenko, V.Analysis is the basis of diagnosis in medical practice. For these purposes, one important source is digital images. Based on this, we look at the digital image of the blood smear. These data allow us to consider the possibility of diagnosing various diseases. Particular attention in the work is paid to certain methods of digital image analysis. The choice of such methods is based on the analysis task. The article presents examples of digital images of a blood smear and the results of their processing.Публікація Informational and Structural - Parametric Models of Inductions Micromotors(IOSR, 2018) Mohammad, A.; Sotnik, S.; Belova, N.; Lyashenko, V.Inductions motors play an important role in various areas of their application. Especially important among such engines are inductions micromotors. The breadth of use of inductions micromotors necessitates the construction of various models for such engines in order to determine the parameters of their design and operation characteristics. The article reviews the designs of existing inductions motors. An information and structural-parametric model for determining the design of inductions micromotors and their main characteristics are proposed. Calculations have been performed for one of the modifications of an inductions micromotor. The effectiveness of the proposed features modification an inductions micromotor is shown. The reliability and efficiency of the developed models for determining the design of the considered modification of an inductions micromotor is shown.Публікація Modeling of the Forming Process for Aluminum Detail(Scholars Middle East Publishers, 2018) Lyashenko, V.; Matarneh, Rami; Sotnik, S.; Belova, N.In the work, modeling of the forming process for aluminum detail was carried out. As a detail, "Pen" is chosen for which the material AK6M2 is determined, taking into account its physico-chemical properties. In the beginning, a 3D detail model is constructed, using the SolidWorks program. Then in the program Nova Flow, entire process of filling the mold in real time, rate of filling the mold cavity with metal, hardening time of the casting was determined. The temperature change dynamics of the casting after filling the mold is investigated. Possible nodes are susceptible to formation of shrinkage shells.Публікація Modern Walking Robots: A Brief Overview(IA-ESTE, 2021) Lyashenko, V.; Ahmad, M. Ayaz; Belova, N.; Sotnik, S.In this review, we would like to present some of the most interesting modern designs of walking robots: bipedal, quadropedal, hexopedal, and octopods. Their advantages and disadvantages are highlighted. It has been determined that structures with eight or more limbs are ineffective due to high level of electricity consumption. The use of more than six number of legs does not give noticeable advantages in profile cross-country ability or maneuverability, however, it allows to reduce the forces and moments of inertia forces due to decrease in mode coefficient (ratio of time spent by propulsor in support to time of entire step), and, consequently, smoother leg movements in swing phase.Публікація Parametric Model of Gyroscopes(Scholars Academic and Scientific Publisher, 2018) Sotnik, S.; Ahmad M. Ayaz; Belova, N.; Lyashenko, V.The classification of gyroscopes based on the parametric model is considered. It is shown that the proposed parametric model can be used as a basis for developing a mathematical model in the process of creating a module for the automated vibration gyroscopes design, mechanical or optical type. Investigations of the failure probability and the failure-free operation probability for a period of 50 hours to 150 hours and for a period of 200 hours to 400 hours were conducted. Parameters and graphical representation of computational models are given.Публікація Some Features in Calculation of Mold Details for Plastic Products(WARSE, 2019) Lyashenko, V.; Syed Khalid Mustafa; Belova, N.; M. Ayaz AhmadThe article considers the relationship of mold details and injection molds. The basic elements of mold details are considered. The calculation method of design data tooling which can be used at design of injection mold is offered. This method gives the chance to provide the necessary accuracy of casting. This allows to determine the rational walls thickness of the injection mold and to define further what type of heat treatment is necessary after formation.Публікація Speech Recognition Systems: A Comparative Review(IOSR, 2017) Matarneh, R.; Maksymova, S.; Lyashenko, V.; Belova, N.Creating voice control for robots is very important and difficult task. Therefore, we consider different systems of speech recognition. We divided them into two main classes: (1) open -source and (2) close-source code. As close-source software the following were selected: Dragon Mobile SDK, Google Speech Recognition API, Siri, Yandex SpeechKit and Microsoft Speech API. While the following were selected as open-source software: CMU Sphinx, Kaldi, Julius, HTK, iAtros, RWTH ASR and Simon. The comparison mainly based on accuracy, API, performance, speed in real-time, response time and compatibility. the variety of comparison axes allow us to make detailed description of the differences and similarities, which in turn enabled us to adopt a careful decision to choose the appropriate system depending on our need.Публікація Voice Control for an Industrial Robot as a Combination of Various Robotic Assembly Process Models(Scientific Research Publishing, 2017) Maksymova, S.; Matarneh, R.; Lyashenko, V.; Belova, N.Models for the design of assembly processes are considered. Various models for the voice control of an industrial robot are considered: a logical model, semantic networks, a frame model and Petri nets. It is shown that this set of models allows describing the process of designing the technological process for an industrial robot. The logical model of the technological process allows you to define logical relationships. A model based on semantic networks describes the relationship between assembly units in a detail. This allows you to determine the order and method of registration, as well as the mutual orientation of assembly units in the product. The frame model provides the ability to streamline the execution of the build process. A model based on Petri nets allows one to describe the type and sequence of technological transitions. Based on the proposed models, a method of voice control for an industrial robot is developed. The basic principles of voice control for an industrial robot are considered.
