Reforming of Energy Sector of Uzbekistan: Transition to Market and Increasing Generation
Get PDFBy 2030, Uzbekistan will need to generate 2 times more electricity than today in order to meet the needs of the economy and the population, or, in other words, to ensure the country's energy security. To achieve this goal which was set by the leadership of the country, the Ministry of Energy of the Republic of Uzbekistan is gradually implementing large-scale projects and coordinating the processes of reforming the industry in order to transfer it to market relations
Review: Li-Fi Future Technology, Architecture, and their Constraints
Get PDFLight Fidelity (Li-Fi) is a network and mobile communication system that uses light to transmit data at fast speeds in both directions. Li-Fi is a wireless network made up of multiple light bulbs that provides a user experience that is very similar to Wi-Fi except that it uses the spectrum of light. Li-Fi is a type of Visible Light Communication (VLC) that uses light as a communication medium instead of wires. Li-Fi hasrecently advanced to address the disadvantages of Wi-Fi. This paper can be used as a reference and source of information for developing Li-Fi technology, it provides an overview of Li-Fi, covering the architecture of Li-Fi and its application environment, the differences between Wi-Fi and Li-Fi technologies, and the limitations of Li-Fi technology based on a review of numerous Li-Fi technology studies, as well as a brief discussion of Li-Fi efficiency and availability

Prediction of Situations That May Occur in Emergency Situations of Bridges by Means of Optical Sensors
Get PDFIn recent years, with the development of materials science and architectural art, ensuring the safety of modern buildings is the top priority while they are developing toward higher, lighter, andmore unique trends. Structural health monitoring (SHM) is currently an extremely effective and vital safeguard measure. Because of the fiber-optic sensor’s (FOS) inherent distinctive advantages (such as small size, lightweight, immunity to electromagnetic interference (EMI) and corrosion, and embeddingcapability), a significant number of innovative sensing systems have been exploited in the civil engineering for SHM used in projects (including buildings, bridges, tunnels, etc.). The purpose ofthis review article is devoted to presenting a summary of the basic principles of various fiber-optic sensors, classification and principles of FOS, typical and functional fiber-optic sensors (FOSs), and the practical application status of the FOS technology in SHM of civil infrastructure
Strategy of Handover in Mobile Relay Group in LTE-Networks
Get PDFThe small cell technology is giving rise to a new field known as mobile cell, which is expected to dominate the networks of the future. Mobile relay is an important component of mobile cells because it enables mobile user equipment (UE) to keep their network connectivity with a high quality of experience to the microcell base station even while they are moving at high speeds in their vehicles. The use of group handover is a great option for managing the large number of handovers that are caused by transferring user equipment (UEs) within the mobile cell. In this research, we present a group handover technique that is both effective and efficient for mobile cells operating in LTE-Advanced systems. Using the group handover approach that has been proposed, a mobile relay node (MRN) that is attached to a high-speed train will transfer all of the communication that is relevant to UEs from the source donor eNB (DeNB) to the target DeNB. moreover, in contrast to the majority of previous works, which make use of a fixed relay design, this work makes use of a mobile relay architecture. The proposed group handover approach was implemented on the mobile cell, which resulted in a significant reduction in numbers of handovers and the probability of calls getting dropped throughout the system
The Latest Digital Information Technologies and Computer Programs in Integration and in Improvement with the Method of Training and Education of Froebel and His "Gifts"
Get PDFThis article shows the integration of the latest information technologies and computer programs with the methodology of F. Fröbel in the early period of children's education in children's educational institutions. The famous method of teaching F. Fröbel, his exercises and "gifts" are known, with the help of which the child begins to learn about objects and the world around him in general, learns the forms of the object, gets acquainted with spatial figures, which further help him master mathematics, geometry, take the initial step into spatial stereometry. He beginsto get acquainted with objects, understanding their properties of smoothness, roughness, and then roundness, sharp edges, that some figures roll, and others fall to their faces, there are figures with which you can do both. "Gifts" by F. Fröbel gradually prepare the child and introduce him to an interesting world. The most interesting is the use of the latest information technologies, platforms, sites for the development of the child along with these gifts. Computer programs and sites created by the author will come to the rescue here. Ready-made online resources of other scientists and teachers. As a result of the research, the author determined the effectiveness of integrated teaching of children by the method of F. Fröbel in the environment of information technologies and computer programs, proving the effectiveness of integrated learning with updated modern methods
