For miniaturized vacuum klystron type devices utilization of a double- gap strip-line cavity with suspended ceramic substrate is very promising. 
The two-mode operating mode of such cavities practically isn't studied enough; so there is the great scientific and practical interest for research of electrodynamic characteristics of cavities during multi-mode operation that correspond to simultaneous excitement of anti-phase and co-phase modes in a double gap.  
In this article results of the 3-D numerical modeling by means of the Ansoft HFSS code are presented, and also the experimental results of the electrodynamic properties of the half-wave double- gap cavity with the suspended ceramic substrate are submitted. Optimum parameters of this design, allowing to carry out simultaneous excitement at multiple frequencies with frequency rate (K=2) are determined.
In such cavity high values of unloaded Q factors isn’t need because dielectric losses and conductor losses can be compensated at the expense of  the negative electronic conductivity that brought by modulated electronic beam. The operating mode with frequency rate   can be used for increasing of efficiency of generating and amplifying micro devices with filament cathode and matrix field emission cathodes.

At present, the development of algorithms is particularly relevant high-level analysis of video sequences, including tracking of objects in a video stream and their implementation in information and communication systems. In the proposed approach the pretreatment step uses optical flow calculation for each frame video sequence, as well as low-level features (such as a representation of each pixel in the color space YIU). For moving objects optical flow is more important than for a stationary background and allows you to find the foreground objects in video sequences and adjust the weighting function in determining the histogram similar to the adjacent frames, taking into account the motion of objects.

The model of the ideal video camera is described, the form of the intrinsic and extrinsic camera parameters is showed. The relations between coordinates of a point in the world coordinate system with coordinates of this point on the image plane are given. The problem of finding extrinsic camera parameters from corresponded world and image points is posed. The error of found extrinsic parameters is estimated by simulation for several configurations of calibration objects consisting of a variable number of points on different distances from the camera and with different angles between them. On the basis of simulation results recommendations are given for the choice of the calibration object in order to improve the accuracy of the extrinsic camera parameters. The best results may be obtained with a configuration consisting of points that have a large angular distance between them and are posed on different distance from camera.

In the present work we report on the study of local atomic and electronic structure of gold nanoparticles funnctionalised by thiol and amine containing long-chain ligands. The study of nanoscale atomic structure is performed by means of X-ray absorption spectroscopy (XANES: X-ray Absorption Near-Edge Structure) and computer simulation. In consequence of the experimantally obtained data analysis and computer simulation it was obtained that strong bonding takes place when 11-mercaptoundecanoic acid is bound to the gold nanoparticles surface, forming a chemical bond Au-S 0.25 nm in length. Weaker bonding is observed when forming bond between dodecylamine and gold nanoparticles surface atom resulting in Au-N bond 0.23 nm in length. Supplementary XANES spectra analysis by means of density functional theory reveals the nature of formation of the investigated nanoscale structure.

The paper deals with the analysis of of the relation to the political life among young people in Rostov-on-Don. It is measured an activity relation to the political life of society, there is assessment of relations to  the political authority, the current political situation and the level of relative deprivation. It is revealed, students possess low electoral and social activity: "don't take part in elections" – 47,4%. In the relation to protest actions the group was stratified on two subgroups: one has a positive attitude towards the antigovernment actions, the second - is negative. The relative deprivation is at the average level, but 1\4 of the group have the high level of deprivation, which may cause a political tensions in the future.

The emotional component of group political installation was measured on technology of semantic differential. It was offered to estimate to respondents on 20 bimodal scales four types political about. Two ideal – ideally positive and ideally negative orders. And two real – local and central. In the linear approximation calculated levels of emotional perception of the political order in the vicinity of the averaged image of the real image of the ideal order to constructs used in the space of features. Perception of an political order in Region: --0,02; in Russia: -0,04 (using a normalization from -1 to +1). That it almost neutral.

2-D and 3-D problems of the elasticity problems for incompressible materials are considered. Solving these problems using the finite-element method results in solving the linear algebraic equations system with sparse matrix. For incompressible materials this system is the system with a saddle point (i.e. the matrix eigen values have different signs). Thus, applying such solving methods as the conjugate gradient method and the generalized minimal residual method is impossible. Uzawa method is suggested to be used for such problems. It is an iterative process, and at each iteration it is necessary to solve the linear algebraic equations system, but this system is without a saddle point. The different variants of Uzawa algorithm are realized within CAE Fidesys software package, and their efficiency is compared in the article.

This paper presents a comparative analysis of the effectiveness of the method Cuthill-McKee algorithm and fill-reducing ordering of a sparse matrix, based on multi-level nested dissection paradigm, developed at the Department of "Computer Science and Engineering," University of Minnesota. For short, we shall call the algorithm Cuthill-McKee CM, and the algorithm of the University of Minnesota — NodeND (Node nested dissection). This article uses a modification of the CM algorithm — RCM (reverse Cuthill-McKee), because in practice the reverse numbering index allows you to get a greater advantage than using a direct algorithm CM. The reason for using these algorithms are high speed computational algorithm, as it is necessary to solve the system proximal to the diagonal, the great acceleration of algorithms for solving FE problems using technology such as CUDA
