In the article the reliability calculations of automatic transformers with adjustable range are performed. Since reliability is one of the main characteristics of current transformers, several parameters of its range are included in the calculation of the reliability of an automatic adjustable current transformer, and as a result, high-precision values of reliability were achieved.

This article examines the effect of alloying elements of high chromium cast iron on the corrosion resistance and hardness of the alloy by heat treatment. Carbide formation and elongation strength limits were also analyzed depending on the amount of chromium and nickel. 

This article discusses the types of yurts of the peoples of Central Asia as well as the construction of houses and their use in the tourism industry of Uzbekistan.

The article discussed and gave recommendations on equipping the outer coatings of the building with modern energy-efficient materials and innovative technologies, creating a microclimate in a residential area through architectural and spatial form and design solutions, and comprehensive use of the solution and the “smart home” style in arranging the internal environment.

The article developed an expression that allows to determine the amplitude values of different harmonics of the magnetizing current at high harmonics caused by the saturation of the magnetic core of the current transformer. Using this expression, it is possible to determine the percentage of the main harmonics obtained for different harmonics, and the determined results allow to accurately set the value of the current (voltage) in the transition state from one range to another to automatically adjust the range of the current transformer.

In this research paper analyzes powder fire extinguishing agents, including their composition. Particular attention is paid to the means of local production. The author describes local fire extinguishing agents, for example, calcium sulfate, phosphogypsum, sodium bicarbonate and ammonium phosphate in powder form.

This research paper deals with the study of the resistance and fire resistance of concrete structures by studying the theories of Galileo Galilei, I. Coulibin, Louis Navier, Arthur Loleit, J. Bernoulli, R. Guk, J.M. Tuglie, V.A. Baldina, A.A. Gvozdev, I.I. Goldenblat, Yu.M. Ivanova, V.M. Keldysh, V.M. Kochenova, L.I. Onishchik, N.S. Streletsky, K.E. Tal, A.V. Zhitkevich, V.M. Moskvin, V.V. Kuraev, P.P. Gedeonov and draws attention to the special properties of vermiculite as a heat-insulating material, taking into account the experience of its use both in Russia and in the United States of America.

In this scientific work, a theoretical analysis of the movement of raw cotton with a uniform feed of the feeder is considered, the cleaning machines used at the cotton ginning plant.

In this paper, we talk about an improved demodulation conspire utilizing the Fractional Fourier Transform for a balance plot utilizing twitter rate move keying, related to the empowers high request, for example more than 32-ary adjustment plans to be attainable with acceptable piece mistake rate execution, even without coding, along these lines conquering restrictions of conventional plans including stage move keying or QAM. By utilizing a FrFT-based demodulator, we grow our demodulation levels of independence from a solitary (for example recurrence) pivot to a whole time-recurrence space, called the Wigner Distribution (WD). We show how the proposed demodulation conspire utilizing the FrFT improves over past methodologies by in excess of 7 dB, empowering us to accomplish near 4-ary execution with a 32-ary tweak plot.

In this study, the assessment of the safety of reservoirs and their hydraulic structures considered reliability criteria related to the quality of design and construction work, natural and anthropogenic impacts during exploitation, exploitation, technical condition and other factors. There are measures to eliminate problems that arise during the exploitation of reservoirs.

Distributed computing is interrelated with discernment for the arrangement of figuring foundation and different administrations. It gives a framework that is adaptable, usable, practically open and movable Information Technology assets that need not be possessed by an individual yet can be conveyed as an administration over the Internet. This paper talks about the impact of Performance Expectancy on the acknowledgment to utilize Cloud Computing inside state funded colleges in Kenya. Blended technique research was utilized with Purposive and Stratified testing being utilized to choose the example populace and the example size was 181 respondents from four state funded colleges which were shown up at by utilizing relative assignment strategy. Polls and meetings were utilized to catch information. The examination set up components, for example, Performance Expectance to be an immediate indicator of worthiness of distributed computing, relocation to the distributed computing ought to be organized and gradual and more individuals would utilize Cloud Computing whenever offered admittance to solid web and PCs.
