This paper presents problems related to systems of linear algebraic equations, which are solved by 3 types: Gaussian, Kramer and Matrix methods. In Problem 1, which is given below, the number of concrete pourers and plumbers in the construction work is calculated using the methods described above. In issue 2, we can find the answer to the question of how many days the designer workers will complete the order.

In the system of higher education, the electronic library system is a system that automates the main processes of the library (collection, cataloging, book circulation) in order to manage resources. In today's world experience, we can see that in developed countries, the performance of electronic library systems, their use, implementation in libraries is very high. In particular, if we look at the history of U.S. librarianship, library automation began in the 1930s to facilitate library processes.

The informatization of society, the globalization of the economy and the development of innovations require a systematic in-depth study, multifaceted analysis of the activities, management and forecasting of economic entities in line with the principles of the new systemic paradigm. The article is devoted to the application of new directions of economic theory in strategic planning. The shortcomings of traditional and evolutionary economic theory in terms of strategic planning are highlighted. It is proposed to use elemental topology such as Action Strategy in the development of strategic plans to ensure the implementation of the measures identified in the plan, the content of the formed principles of strategic planning, the mission, views and objectives of the economic system

Innovations in education have been improving over the years. In ancient times, people had no idea about programs that could calculate mathematics and draw graphs. The most popular of these programs is MathCAD. Today, anyone who is fluent in Russian and English can use MathCAD without any difficulty. This program allows us to draw and imagine various complex graphs as well as work examples in all areas of mathematics. In this program, geometric shapes can be built from all sides. This shapes the ability to think.

In this manuscript,it was investigated that the mechanism of recombinational processes in the film of a-Si: H <B> in terms of the dependence of Stationary photoconductivity on temperature(The method of the dependence of Steady-State Photoconductivity on temperature). By using the solutions of continuity and electric equilibrium equations, they were explained that non-monotony and rebombination processes is differently related to D-centers by division temperature into two intervals for the strongly absorbed a -Si:H<B> are evident from the relation of σ ~ σ0(1/T).

In communication and communication devices, power equipment, relay protection and automation terminals, in the electric power industry of “smart” cities and houses, in industry, in railway transport, microprocessor relay protection and automation devices, distributed generation installations, including renewable energy sources, and storage devices are beginning to be used. electricity, as well as "intelligent" automated information and measurement systems. They widely use non-contact converters of direct and alternating currents of monitoring and control systems. Their disadvantages are a narrow range of controlled currents, large dimensions and weight. Therefore, it is important to eliminate them. The paper considers the general principles for constructing non-contact high DC converters, the main requirements for them, and shows the results of developing one of the options proposed by us, universal non-contact magneto-modulating high DC converters with an extended range for various monitoring and control systems. They differ from the known extended controllable range with small dimensions and weight and increased accuracy and sensitivity. The converter has a simple and technologically advanced design with low material consumption and cost, and can non-contactly control large direct currents, as well as alternating currents. The paper considers errors from external magnetic fields of universal contactless transducers of monitoring and control systems. It is shown that the error from the external magnetic field does not exceed 0.08% if the number of sections of the measuring winding is even and with their symmetrical arrangement, and with their even increase, the error decreases.
