Öğe Architecture, Protocols, and Applications of the Internet of Medical Things (IoMT)(Engineering and Technology Publishing, 2022) Askar, N.A.; Habbal, A.; Mohammed, A.H.; Sajat, M.S.; Yusupov, Z.; Kodirov, D.The Internet of Things (IoT) refers to the interconnected framework of web-connected objects that can collect and transfer information over a remote network without requiring any human intervention. The rapid progression in the development of IoT-based devices and their expansion towards making the medical care facility financially more savvy, proactive, and customized, has given rise to the development of the "Internet of Medical Things (IoMT)" that are assumed to function proactively in all domains of the healthcare industry. Within this framework, the IoMT-based healthcare system delivers various advantages, such as quick and unfailing treatment, enhanced communication, cost minimization, etc., through the exploitation of several new technologies. For instance, machine learning has significantly helped with the exploitation of various healthcare systems; fog computing not only minimises the cost of communication but also provides low latency; blockchain delivers its users a much better way of protecting sensitive and confidential information and data they possess. In this survey, a comprehensive elaboration of the IoMT-based healthcare systems based on modern technologies was conducted. This article describes various techniques and solutions of IoMT healthcare systems in the context of emerging technologies, and the related future trends and applications for a better understanding of how IoMT can enhance the healthcare industry now and in future. © 2022 Journal of Communications and 2022 by the authors.Öğe Fault control of microgrid system: A case study of Karabuk University-Turkey(IOP Publishing Ltd, 2020) Yusupov, Z.; Almagrahi, N.; Tursunov, O.; Kodirov, D.; Almgarbj, H.A.; Toshpulatov, N.In this paper Karabuk University microgrid system is introduced and fault control of microgrid is analyzed. The microgrid system of Karabuk University campus consists of diesel generator, solar PV panels, energy storage unit, critical and non-critical loads. Simulation of microgrid in both grid-connected and isolated operation modes are conducted on MATLAB/Simulink. The fault control has been implemented in the microgrid system to effectively manage of power in the system. The system is effectively disconnecting the microgrid from main grid within a microsecond after fault conditions. The distributed energy sources have been supplying the energy to load based load profile settings. From the simulation results, the developed control mechanisms provide stable operation in the microgrid system. © Published under licence by IOP Publishing Ltd.Öğe Modeling and Control of Decentralized Microgrid Based on Renewable Energy and Electric Vehicle Charging Station(Springer Science and Business Media Deutschland GmbH, 2024) Yusupov, Z.; Almagrahi, N.; Yaghoubi, E.; Yaghoubi, E.; Habbal, A.; Kodirov, D.Energy scarcity, environmental pollution, and the exponential rise in demand for energy are all significant global problems. The integration of distributed energy resources (DER) into electric power systems (EPS) and the use of electric vehicles (EVs) due to low pollution has increased in recent decades. The operating reliability and efficiency of the power systems are affected when DERs and energy storage devices are integrated into a distribution network. In a different scenario, a vital step toward low-carbon mobility is the electrification of automobiles. To integrate the widespread adoption of electric vehicles into EPS, it is necessary to coordinate the combination of centralized and decentralized control of EPS at the EV grid infrastructure. In this paper, a microgrid (MG) with decentralized control of renewable energy and an EV charging station is designed and modeled for Karabuk University campus. In the proposed mathematical model, the Park transformer is applied based on injection current in the Point of Common Coupling (PCC) and using the PI controller to control active power. This technique can keep the frequency and power in both grid-connected and islanded modes, also significantly reducing the number of harmonics in the grid-connected mode. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.Öğe Study on issues of uninterrupted power supply, energy-saving and improving the quality of electrical energy of water facilities(IOP Publishing Ltd, 2020) Toshpulatov, N.; Tursunov, O.; Kodirov, D.; Maksumkhanova, A.; Yusupov, Z.This paper analyses the results of studies of uninterrupted power supply, energy saving issues, problems of improving the quality of electrical energy of irrigation pumping stations and electrical consumers of water facilities. The current state of the power supply system is described, and the analysis of the existing situation is carried out. On the basis of comparison of theoretical calculations and practical measurements of the consumption of electrical energy, discrepancies in the results were determined. A solution was found to the problem of reducing the actual consumption in relation to the calculated ones. Recommendations are given for ensuring uninterrupted power supply, solving the issues of increasing the energy efficiency of the equipment in operation for energy conservation and saving electrical energy by improving quality indicators. © Published under licence by IOP Publishing Ltd.Öğe Using of evaporative cooling systems in poultry farms(IOP Publishing Ltd, 2020) Anarbaev, A.; Zakhidov, R.; Tursunov, O.; Kodirov, D.; Vakhidov, U.; Khaliknazarov, U.; Yusupov, Z.This article is devoted to the development of promising low-power evaporative cooling systems in poultry farms. At the same time, the placement of elements of the system in determining the temperature, humidity and gas composition of the air in such indoor areas is determined by the parameters at which the most favorable conditions for the life of their bodies and their high productivity are created. The promising method of intensifying the process of heat and mass transfer between gaseous and liquid is considered. The article presents the structural and thermodynamic parameters of the developed evaporative cooler air. Create a layout of the plant shown efficiency and effectiveness of the cooling air. Preliminary methods of calculation thermodynamic parameters of this installation are presented for the conditions of the Republic of Uzbekistan and are more effective with comparison in widely used at present time I-d diagram. © Published under licence by IOP Publishing Ltd.
