U/Pb Age of detrital zircons from sandstones of the upper emsian diamond takaty formation of the Western Urals

Pyzhova E.S., Popova N.S.

Abstract

The first results of U/Pb (LA-ICP-MS) dating of detrital zircons from quartz sandstones of the Devonian Takaty Formation are presented. The obtained ages span a range from 1857.5 ± 53.8 to 3054.0 ± ± 48.0 Ma. The vast «gap» (~1.5 Ga) between sedimentary age of Takaty Formation and the age of the youngest zircon grain is fixed. A comparison of known ages of crystalline complexes from the Volga-Uralian part of East-European Platform with obtained ages of detrital zircons from Takaty Formation supports the «Volgo-Uralian» origin of the zircons. This implies the existence of a previously unknown stage of kimberlitic magmatism, much more ancient than the stage of kimberlitic magmatism formed diamonds in Arkhangelsk and Timan provinces.

Morphomet52ric characterization parameters of river basin of Manabi

Antonio Fermin Campos Cedeno -., Sinichenko E.K., Gritsuk I.I.

Abstract

This paper presents an analysis of several methods so far developed to characterize the drainage networks of watersheds, indicating their relevant properties. On the other hand, is elaborated an extract of certain laws, on which the watershed morphometry is based to characterize the drainage potential of watersheds. Finally, based on the proposed framework, is performed the estimation of compactness index and river density of Manabi watersheds, as important input to the design of hydraulic works in the province of Manabi and Ecuador related to the management of watersheds.

Pilot study of influence of solar radiation on intensity of snowmelt

Gritsuk I.I., Debolskiy V.K., Maslikova O.Y., Ponomarev N.K., Sinichenko E.K.

Abstract

In the hydraulic laboratory of People's Friendship University of Russia a series of experiments to study the various possible external influences on the process of snow melting were carried out at the facility, which allows to measure the amount of seepage flow in time. The laboratory investigations of the continuous snow melting and infiltration of melt water into the ground, depending on the properties of the snow (initial density, thickness and temperature) were carried out. The impact of rain flows and radiation of the sun on the snow-melting process were examined, carried out experiments with exposure to infrared (IR) and ultraviolet (UV) radiation on the snow. The work is a continuation of the study of the dynamics of the coastal slope of the water bodies in a permafrost [1].

Two-stage synthesis of control system by the network operator method

Diveev A.I., Shmalko E.Y.

Abstract

The paper focuses on the problem of control system synthesis and a numerical method of the network operator is proposed to search a solution. Apart from a well-known approach when the stated control synthesis problem is solved directly by the method of network operator considering given criteria and terminal conditions, the present paper describes a two-stage synthesis. The first stage is supposed to solve numerically a set of optimal control tasks for different initial values from some given space. The second stage makes an approximation of the previously received optimal trajectories by means of the network operator. An example illustrates the two-stage synthesis of a control system for a spaceship descent to the Moon.

The little deflections of the previously intense ideal plastic beams with the regional moments and load distribution

Monakhov I.A., Basov U.K.

Abstract

In the work up the technique of the decision of problems about the little deflections of beams from ideal heard-plastic material, with various kinds of fastening, for want of action of the asymmetrically distributed loads with allowance for of preliminary stretching-compression is developed. The developed technique is applied for research of the strained-deformed condition of beams, and also for calculation of a deflection of beams with allowance for of geometrical nonlinearity.

Abstract

The paper deals with the solution of pure bending of rectangular beam AK4-1T at constant temperature loaded constant bending moment. The research of construction for creep and long-term strength with the whole distribution pattern of the stress until the beginning of destruction considered. The numerical calculation of the problem is solved with the equations of the energy variant of the theory of creep, as well as the method of the solution continuation with respect to a parameter and the best parameterization, using four methods of numerical integration of ordinary differential equations: Euler method, Euler-Cauchy method, fourth-order Runge-Kutta method and fourth-order Adams method. The paper also considers comparison of two methods for the solution of the numerical results and a comparison of the numerical solutions with the experimental data as well.
