The object of the study is the process of energy management in the municipal sector. The purpose of the study is to develop an intelligent energy management system in the public utilities sector. To achieve this goal, the following tasks were solved: the main problems of energy efficiency in the housing and communal services sector were analyzed and ways to solve them using modern technologies were proposed; the methodology for developing an intelligent system (SmartGrid) was chosen; the architecture of an intelligent energy management system was proposed; the algorithm of the intelligent energy saving management component was presented; to determine the electricity consumption in the system, a methodology was used that involves the collection and analysis of data from the Machine learning algorithms, such as the support vector method, neural networks, and decision trees, are used to determine the optimal mode of energy consumption.

The cases of insufficient amount of a priori data for correct<br>classification are considered; heuristic methods of selection according to criteria of basic prototypes and information<br>priorities are proposed.</p> Victoria NEVLYUDOVA, Nikolay STARODUBTSEV Copyright (c) 2023 Journal of Natural Sciences and Technologies https://creativecommons.org/licenses/by/4.0 https://journalofnastech.com/index.php/pub/article/view/36 Mon, 18 Dec 2023 00:00:00 +0300 SYNTHESES AND STRUCTURAL ANALYSES OF HETERONUCLEAR HEXACYANOMETALLATE(III) COMPLEXES WITH 4-(2-AMINOETHYL)PYRIDINE https://journalofnastech.com/index.php/pub/article/view/28 <p>In this study, the complexes,&nbsp; given with the formula (NH<sub>4</sub>)[Cd(µ-4aepy)<sub>2</sub>Fe(µ-CN)<sub>2</sub>(CN)<sub>4</sub>]<sub>n</sub> and (NH<sub>4</sub>)[Cd(µ-4aepy)<sub>2</sub>Co(µ-CN)<sub>2</sub>(CN)<sub>4</sub>]<sub>n</sub>,,&nbsp; obtained by using cadmium(II), 4-(2-aminoethyl)pyridine (4aepy) and hexacyanoferrate(III) or hexacyanocobaltate(III) were synthesized as powder. Structural characterizations of the obtained compounds were investigated by vibration (FT-IR and Raman) spectroscopy, elemental, thermal and powder-XRD techniques. Vibration spectra of the complexes were recorded between 4000-225 cm<sup>-1</sup> and were confirmed by the results of thermal and elemental analyses. The structural properties of the complexes were investigated by considering the characteristic bands of the ligands from the vibration spectra. Additionally, vibration spectra of the complexes were observed two different ν(CN) absorption bands which act as bridge and terminal. The spectral data show that the characteristic bands of 4aepy were shifted to lower and high frequencies. These shifts arise due to bounding metal and coupling of metal-ligand vibration modes. Thermal behaviors of the complexes are investigated between the temperature ranges of 30-1000 °C in static air atmosphere.&nbsp;&nbsp;&nbsp;&nbsp;</p> Seray KEKEC, Güneş Süheyla KÜRKÇÜOĞLU Copyright (c) 2023 Journal of Natural Sciences and Technologies https://creativecommons.org/licenses/by/4.0 https://journalofnastech.com/index.php/pub/article/view/28 Mon, 18 Dec 2023 00:00:00 +0300 SHUTTLE-BASED STORAGE AND RETRIEVAL SYSTEM 3D MODEL IMPROVEMENT AND DEVELOPMENT https://journalofnastech.com/index.php/pub/article/view/33 <p>The development of new design solutions for Radioshuttle will increase the storage density of heterogeneous goods, increase the efficiency and productivity of warehouse logistics, reduce the cost of renting warehouse space and reduce the negative impact on the environment, which makes this development extremely relevant and necessary in modern logistics<strong>.</strong></p> <p>Authors proposed to improve the designs of the Radioshuttle, through the use of the Mecanum Wheel.

Thus, it is known that the oxidation of hydrocarbons can proceed with the formation of soft and deep oxidation products. Finding the factors that determine one or the other direction of the reaction means obtaining a method for controlling the selectivity of the process. For a few catalytic oxidation reactions, there is reliable information about their mechanism</p> Ulkar SHIRALIYEVA, Elmira HUSEYNOVA, Aida RZAYEVA, Zarifa MAMMADOVA, Saida NADJAFOVA, Nurana MARDANOVA Copyright (c) 2023 Journal of Natural Sciences and Technologies https://creativecommons.org/licenses/by/4.0 https://journalofnastech.com/index.php/pub/article/view/29 Mon, 18 Dec 2023 00:00:00 +0300 SIMULATION OF FLEXIBLE PRINTED STRUCTURES DESIGN FOR MOBILE ROBOT PLATFORM https://journalofnastech.com/index.php/pub/article/view/35 <p>The mobile robot platform was designed for remote performing of special tasks for various fields.

Such changes set manufacturers the task of automating production process control in real time, which involves creating a single enterprise information space that links together the technological and business levels of enterprise management, while solving many of the most important tasks for an industrial enterprise.</p> <p>Integration of the cyber component allows automating the management of production processes through the use of intelligent mechatronic modules, expert systems and large data sets for production forecasting. In this context, a person controls processes at the physical level through a cybernetic system. At the same time, this system with minimal human involvement allows: automatic control of the vehicle at the physical level, analysis and decision-making in real time. Systems of this type are multilevel. At the lower level, accurate and reliable systems such as microelectromechanical and micro-optomechanical are used. They collect, process, and transmit information in the control of technological systems. The accuracy and durability of MEMS and MOEMS depends on the technology of their manufacture.</p> <p>The aim of this work is to increase the efficiency of control by using proximity sensors based on MEMS and MOEMS as part of technical automation means</p> Olena CHALA, Igor NEVLIUDOV, Shakhın OMAROV, Serhii TESLIUK Copyright (c) 2023 Journal of Natural Sciences and Technologies https://creativecommons.org/licenses/by/4.0 https://journalofnastech.com/index.php/pub/article/view/34 Mon, 18 Dec 2023 00:00:00 +0300
