Annotation: The analytical method of evaluation of the numerical characteristics of GERT-homogeneous networks such as the mean and variance. The method is based on the transformation of GERT-network to an equivalent arc with the conversion of numerical characteristics of random variables of the arcs on the proposed formulas.

Annotation: The computational technologies for fast and accurate modeling of infrared spectra to be measured by IRFS-2 and MSU-MR sounders which are planned to be installed on board of Russian meteorological Meteor-M satellites are under consideration. Methodological aspects of fast radiative transfer model development are briefly described. Interface and functionality of the developed software is presented, its accuracy and performance are assessed

Annotation: In this article was used model of non-linear pendulum for finding optimal shape of a curved strip. The shapes with bend point presents via elliptic functions. Result of the article allows to improve construction of an aerial of satellite.

Annotation: The structure of «posts» for storage in social networks with a small amount of users is offered. The developers face the problem of choosing an effective system of information storage. The data structures created in the work consider features of no-SQL and SQL storages of data. Productivity of each models is checked on inquiries of different complexity to databases of different structure. The efficiency of the offered structures is checked on concrete data

Annotation: Developed computer algorithms that simulate the dynamic interaction of elastic blocks through thin viscoelastic layer in structurally inhomogeneous media such as rocks. On the basis of rheological models are constructed for the deformation of the material layers of different levels of complexity. In the numerical solution of one-dimensional problems of applied monotonous grid- characteristic schemes with a balanced number of time steps in the blocks and interlayers . The problems of software implementation of algorithms on multiprocessor systems with graphics cards . Numerical results demonstrate the qualitative features of the propagation of plane waves in materials with a layered microstructure.
