This article presents the results of the reconstruction of surface temperature above the northeast part of the Iceland basin (Northeast Atlantic) for the last 300,000 years with help of the M. S. Barash method, as well as the RAM, MAT and TFT methods on the basis of the planktonic foraminifera data. The M. S....

... of atmospheric pressure, wind direction and speed, and air temperature from the automatic hydrometeorological station located offshore, as well as the satellite data from the infrared and microwave (radar images) ranges to determine sea ice and sea surface temperature, respectively. The research also reveals characteristic fea­tures of long-term dynamics of hydrological conditions in the south-eastern part of the Baltic Sea for 2005—2019. The average annual atmospheric pres­sure is close to ...

The smooth surface in affine space is considered. With the derivation formulas and equations of the structure of an affine space constructed three pairs Akivis-Laptev on the surface. It is shown that the surface of an affine space is a holonomic smooth manifold....

The most considerable increase in the temperature of soil surface was observed in the cold period (1,5 °С, a 53,9% rise in temperature), the smallest in August (0,3 °С, 2,1 %), whereas, in May-June, the increase was negative (–1,3 °С, 27,1 %). Major increases in air temperature take place in April-July,...

Investigated by atomic force microscopy and Auger electron spectrometry the surface of films CdS, formed by hydrochemical deposition on textured silicon substrate. It is shown that the film CdS thus manufactured characterized inhomogeneous distribution of size structural elements and chemical composition over the surface. These ...

Parameterizations of some surfaces using functions of a complex variable are considered, while obtaining different coordinate grids. The possibility of modeling bodies by setting the General projection area is described. Kochina A. S. complex function, conformal maps, ...

... sea in summer 2018. The data of the MODIS radiometer installed on Aqua and Terra satellites were used for the analysis. The average concentration of chlorophyll "a" in the warm period of 2018 (May-August) was 3.8 mg/m3 while the average sea surface temperature was 17.7° С. The Maximum concentration of chlorophyll "a" (8.1 mg/m3) was rec­orded in May. However, the most massive development of phytoplankton oc­curred in July — the average monthly concentration of chlorophyll ...

An approximate solution of the problem of the structure and characteris­tics of a stationary nonlinear periodic wave on the surface of a liquid of finite depth has been obtained. The solution is as follows: first, the kinematic and dynamic conditions are simplified. The Bernoulli integral contributes to the simplification of the dynamic condition. An integral operator of convolution ...

The article is devoted to the definition of methodological approaches to the development of multi-channel duplex radio communication systems that en­sure reliable operation on a surface vessel. The research provides analytical expressions for the calculation of the possible number of transmit-receive channels in the model, depending on the signal spectrum width in the chan­nel. The proposed software allows you to quickly calculate ...

There is described multifunctional surface small aperture aerial technology of microseismic monitoring. This technology is used for monitoring of hydraulic fractioning, fluid injection and for other well interventions. In addition it allows to describe crosshole block discontinues structures ...

This article considers the problem of 3D visualization of two examples of top movement along a smooth surface. The authors analyze the cases where analytical solutions are possible. Graphical illustrations to these solutions are provided. 1. Голубева О. В. Теоретическая механика. М., 1961. 2. Суслов Г. К. Теоретическая ...

The restoration factor is experimentally defined at blow of ball about a motionless oblique surface. It is shown that the restoration factor is function of an angle of slope. 1. Великанов Н. Л., Наумов В. А., Примак Л. В. и др. Совершенствование предпроектных расчетов по ...

This paper summarizes the results of gravity surveys conducted across two palaeoincisions cut into the sub-Quaternary surface in the coastal area of the Kaliningrad region near Svetlogorsk. Strong local negative anomalies caused by the palaeoincisions are observed on the gravity anomaly profiles. The analysis of the palaeoincision's spatial distribution by using gravity ...

This article considers the effect of the order of B-splines on the appearance of surface and smoothness degree. The surfaces based on B-splines of 2 x 2, 3 x 3, and 5 x 5 orders are presented. Кochinа A., Slobodyanyuk M B-splines, programming, modeling, smooth surfaces, computer graphics. 124-126

The estimation of limiting sensitivity of digital holographic methods of measurements of a surface of movings is lead}. Influence of a degree of digitization of hardware on limiting the sensitivity of digital holographic measurements is analysed. Parameters of surface — acoustic waves with amplitudes of fluctuations less than 10 nanometers ...
