A POETIC DESCRIPTION OF THE PHILOSOPHY OF HARMONY BETWEEN MAN AND NATURE IN THE NOVEL “BLACK WHIRLWIND”

In this article, the author N.Norkobilov's novel "Black whirlwind" is studied in terms of human and nature problems. The novel reflects the poetic reflection of the same problem, the literary and philosophical scope, the national identity. The philosophy of the novel, which emerged in the course of the literary contrast and comparison of social and natural laws, is illuminated through the analysis of several important episodes.Keywords: novel, plot, image, detail, character, portrait, epic image, symbol, figurative image, literary contrast, human and nature problem, plant, community, animal, tragedy, dramatic

Development Of Technology For Producing Thermally Strengthened Reinforcement Rolled

The article discusses the results of research on the development of the chemical composition and mechanical properties of reinforcement No. 12 made of steel grade 22C, as well as the development of a technology for obtaining thermomechanically hardened coiled rebar. It is shown that the proposed profile provides better hardenability of the rolled section and increases the efficiency of water cooling. The best results in terms of mechanical properties were obtained for rolled products made of steel grade 460B. A method of hot rolling of steel and a method of production of reinforcing bars of increased strength are proposed, one of the important components of which is microalloyed vanadium in the range of 0.04-0.10%, which will ensure an increase in the strength level up to 30%. The results of mechanical tests of coiled reinforcing bars and comparative data on the mechanical properties of reinforcement No. 12 rolled on mill 320 are also presented. It is shown that the use of steel microalloyed with vanadium makes it possible to obtain reinforcing bars with an effective profile with a nominal diameter of 5.5—8.0 mm, class A500C, in a temperature range acceptable for the equipment of mill 150

Analysis of Methods for Solving Optimal Control Problems Train Movements

Optimal train management has been an active research topic for many years. All over the world, important measures are being taken to use electricity efficiently due to the growing demand for energy resources. Such measures are also being taken in the railway industry. The overall objective is to operate the train in such a way as to minimize the overall energy consumption, taking into account the time and physical constraints imposed by the train and the operating conditions. The achievement of this goal is ensured by advanced technologies currently used on electric rolling stock and new computer capabilities. The lion's share of electricity consumption in railway transport is accounted for by the cost of train traction. Therefore, measures aimed at optimizing electricity consumption by electric locomotives and electric trains are relevant. Optimization is a powerful tool and a promising solution to any problems associated with the operation of railway transport. The ever-increasing complexity of engineering systems, the growing demand for accuracy and the search for optimal and reliable designs create additional difficulties that can only be solved by developing optimization models. In theory, optimization is the process of maximizing or minimizing an objective function by sequentially selecting and calculating possible results within a certain set of parameters. In the context of growing competition in the transportation market, the interest in energy efficiency among railway companies in recent years has become the subject of increased interest, both for the modernization of existing vehicles and for the acquisition of new ones

On the Hamiltonian form of the Einstein equations for gravitational field

It is shown that Einstein gravitational equations and canonical equations following from the Dirac-Schwinger Hamiltonian in the Faddeev variables coincide. For proving of this at first, the Einstein equations has been rewritten in canonical variables, and after this, the time derivative of the generalized momenta of the gravitational field in Faddeev form has been calculated using canonical Poisson brackets. The results coincide.Comment: 7 page

Development Of Software For Solving Multistage Problems By The Method Of Dynamic Programming With Separabel Breaking

This paper discusses how to solve multi-step processes in the form of a matrix and solve problems through dynamic programming. Typically, in practice, the problem of constructing models of multi-stage processes is, as a rule, complicated by the versatility, uncertainty and nonlinearity of the modeled objects, complete or partial lack of expert experience and analytical description of the dependencies. The transition from one state to another is manifested as a function, and when the study is carried out at the analytical level, additional conditions are required, such as the production of the first, sometimes the second, function. If we express the state of multi-step procedures in the form of a matrix, the problem can be solved using dynamic programmin
