Moscow Power Engineering Institute is one of the largest institutions of its kind, and is one of the leading technical universities in the world in the area of power engineering, electronics and IT. It is located in Moscow, Russia, and was founded in 1930. In Russian Federation the education in universities is available in Russian medium only. Therefore, before the main education courses would start, the foreign applicants to university courses should pass the Preliminary course for training in Russian language, followed by the State Test in Russian language . Fifteen years ago MPEI launched the program of education for foreign students in English medium, however in only one specialty – Computer Engineering. MPEI invested considerate time and resources into this program, they selected a group of leading professors who spoke English fluently, who in turn prepared the educational materials in English. Now MPEI accepts annually one full group of foreign students who speak English fluently for this IT educational program in English Language. All classes here are provided in English, hence the students in this program do not require the preliminary training in Russian language, i.e. the educational period becomes one year shorter. The annual tuition fee for this program however is more expensive, since this program is conducted in English, unlike the rest of the programs. Wikipedia.

Regimes of deteriorated (with peaks of the wall temperature) heat release under a turbulent flow of carbon dioxide in a round pipe under supercritical pressure are calculated. The calculation is based on a system of motion, continuity, and energy equations written in the narrow channel approximation. The buoyancy force was neglected. A model of turbulent stress and turbulent thermal flow with allowance for the joint influence of density pulsations and thermal acceleration is proposed. The calculation results for the variation in the wall temperature and resistance coefficients along the well agree with available experimental data. An explanation for the causes of the appearance of a peak in the wall temperature distribution along the pipe in the region where the fluid temperature is close to the pseudocritical temperature is presented. © 2014, Pleiades Publishing, Ltd.

The author presents a technique to calculate instrument stellar magnitudes for silicon photosensors used in modern star trackers as well as estimates the error of the said technique. The technique implies calculation of instrument stellar magnitudes as specifically selected functions of color indices B-V, V-J of the Tycho-2 and two micron all sky survey (2MASS) catalogs. This function is a sum of basis functions with coefficients determined based on star trackers' response. The coefficients are calculated individually for each star tracker response. Calculation of the coefficients of the function is done using the least squares method for color indices of artificial stars. Spectra of artificial stars are created on the basis of reddening of typical subclasses spectra without interstellar extinction, such spectra taken from the Pickles catalog. Thickness of interstellar medium for reddening is selected basing on random law. Validation of accuracy of the proposed methodology is performed by calculating star brightness for standard photometric bands R and I and subsequent comparison of the obtained results with actual data. Such check indicates that the root-mean-square deviation of error is not over 0.08 m. Due to usage of data related to star brightness in J band of 2MASS catalog, the number of stars in the guide star catalog is increased by 30% as compared with using data only from Tycho and HIPPARCOS catalogs. © 2012 Society of Photo-Optical Instrumentation Engineers.

In practice it is often necessary to conduct analysis of systems, with multilayer objects, each layer of which has individual properties. Deformations and stresses inside a system consisting of an arbitrary finite number of thickwalled spheres are investigated in the present article. Each sphere is characterized by its elastic modules. The zone of contact between each of the spheres is continuous on the surface. This problem can be completely solved analyticaly. The relations of pressure on the limits of the sphres, stress tensors and deformations inside the spheres are obtained. The findings have the relevant practical value. Source

We consider the problem for eigenvalues of a perturbed two-dimensional oscillator in the case of a resonance frequency. The exciting potential is given by a Hartree-type integral operator with a smooth self-action potential. We find asymptotic eigenvalues and asymptotic eigenfunctions near the upper boundary of spectral clusters, which form around energy levels of the nonperturbed operator. To calculate them, we use asymptotic formulas for quantum means. © 2014 Pleiades Publishing, Ltd. Source

In the framework of the adiabatic approximation for a subsystem of nuclei with the average distance between them significantly exceeding the dimensions of the initial atom, we consider a nonrelativistic Coulomb system consisting of electrons and nuclei of one type for the temperature range where we can restrict ourself to using the ground state to describe the electron subsystem. We show that the equilibrium properties of such a system are equivalent to the thermodynamic properties of the one-component system of initial atoms interacting between themselves via a short-range potential that is the effective potential of the nucleus-nucleus interaction. In the framework of the applicability of Boltzmann statistics, we present quantum group expansions for the thermodynamic properties of a chemically reacting rarified gas that correspond to the method of initial atoms. © 2014 Pleiades Publishing, Ltd.
