COMPUTER GRAPHICS AND DESIGN SCIENCE AND ITS APPLICATIONS

Abdulkadir Ozdemir, G. A. Majidova

It is important to use advanced and modern teaching methods and implement new pedagogical technologies to master the science of computer graphics and design. Textbooks, educational and methodical manuals, lecture texts, standards, handouts, electronic materials, presentations, video lessons, virtual stands and advanced pedagogical technologies are used in mastering the subject. A variety of graphics in the field of computer graphics and design science creation of objects, results of experiments in the form of text, images and raster graphics graphic applications necessary for processing, as well as creating illustrations great attention is paid to the use of graphic editors.

ERROR DETERMINATION OF RANGE-VERIFIED FERROMAGNETIC CURRENT TRANSFORMERS

Shoyimov Y.Y., Jalolov I.S., Abdullaev J.N., Khamrayev S.G.

Increasing the reliability of ferromagnetic current transducers, the range of which is adjusted. During the trial period, the defunct FMTO was not replaced by a new one. Total trial period T0=200·103s during this period, the isolation of the lungs, the failure of their input and output parts, and the FMTOS find and calculate the failure intensity, upper limit, double reliability marginal values of the 90% resource of the working state change. .A source of error that leads to a random change in the measured current value, that is, the study of the appearance of high harmonics in the measured current as a result of transient processes occurring in the energy system and short circuits as a result of the transition of magnetic materials(generators, power transformers, etc.) to the saturation part of the magnetization characteristic

TECHNOLOGY FOR ENHANCING THE EFFECTIVENESS OF COGNITIVE ACTIVITY IN A CHEMISTRY COURSE

Elmurodov B.

One of the main tasks of education, in accordance with modern ideas, is to create conditions for the formation and development of creative thinking among students in the learning process. Effective organization of cognitive activity is the primary task in solving this problem. From the perspective of a systems approach, the learning process itself is a complex dynamic system that obeys the laws common to systems. The system control mechanism is cyclic feedback (recursion). We learn through repetition. Learning is making decisions and changing actions in response to feedback received. There is a distinction between simple learning - a balancing feedback loop, it is aimed at adaptation and gaining stability. In terms of functioning, it includes procedures, technologies, one or another system of work, trial and error, and rote memorization.

SOLUTION OF DIFFERENTIAL EQUATION WITH FINITE DIFFERENCE METHOD OF CARDIOVASCULAR SYSTEM

Nurjabova D., Kutdusova Elmira Raufovna

This abstract considers the process of solving a parabolic differential equation by the finite difference method. The method is based on discretization of space and time, approximation of derivatives and subsequent calculation of function values on a grid. The solution of the system of equations is performed using an explicit or implicit scheme. In the explicit scheme, the function values in the new time layer are calculated based on the function values in the previous layer. In the implicit scheme, the function values in the new layer are found as a solution to a system of equations. For the implicit scheme, iterative methods are used.
