STUDY OF SEASONAL TREND-PROCESS WITH THE METHOD OF CLASSICAL STATISTICS
Description
This work is devoted to the methods of multicriteria optimization and classical statistics of obtaining pre-estimated information for time series that have long-term memory, which is why their levels do not satisfy the independence property, and therefore the classical prediction methods may be inadequate. The developed methods of obtaining such information are based on classical statistics methods such as mathematical statistics, multicriteria optimization and extreme value theory. The effectiveness of the proposed approach has been demonstrated on the example of specific time series of volumes of mountain rivers

COMPUTER-STATISTICAL METHODS: STATE AND PROSPECTS
01.00.00 Physical-mathematical sciences
Description
We have analyzed the current state of the main computer-statistical methods, identified achievements and existing problems, outlined the prospects of further movement and formulated the problems to be solved. We have also discussed the Monte Carlo methods, pseudo-random numbers, simulation, bootstrap and resampling, the automated system-cognitive analysis. We have considered the applications of computer statistics in controlling and properties of statistical packages as the tools for researchers

CULTURAL STUDIES IN THE CONTEXT OF MODERN HUMANITARIAN PARADIGM
Description
The article reveals the role of cultural studies in the process of learning of sociocultural attitudes, value orientations, stereotypes revealed in the process of reading various literary texts. The leading method of cultural studies in the framework of the modern cultural paradigm is the method of understanding. A teacher creates a problem situation which is necessary for the process of mental activity and that actualizes the value orientations of a personality and creates a space for reflection on the semantre field of the problem to solve

MATHEMATICAL MODEL OF A MACHINE AND TRACTOR UNIT WITH EDM IN TRANSMISSION OF A TRACTOR
Description
The developed mathematical model of the machine and tractor unit with the elastically damping mechanism in transmission of a tractor is given in the article. The analysis of mathematical model of the arable unit on the basis of a tractor with EDM in transmission showed that the MTU mathematical model can be considered as working

Description
The article considers discrete automatic machines with memory, designed for searching the values of parameters of the system optimizing a merit figure of the system, described by some criterion function. The problem of multiple parameter optimization is shown as a problem of discrete optimization by means of representation of values of parameters of the optimized system in the form of a set of discrete values with a specified step of digitization
