"One of the major drawbacks of modern alloyed metal cathodes Pd-Ba is the inhomogeneous distribution of the intermetallic Pd5Ba in the matrix Pd. This fact leads to an underestimation of life and technical performance of devices of microwave electronics on the basis of the cathodes. A substantial improvement in uniformity of cathode alloys Pd-Ba should lead the operation of mechanical activation of powder Pd, carried out prior to its compression process. The paper studied the effect of mechanical activation on the particle shape, particle size distribution and dispersion of powder Pd. It is shown that mechanical activation results in a substantial reduction in the average size and average particle size of Pd powder, as well as a substantial increase of the specific surface of the particles. The optimal regimes of mechanical activation of powder of Pd with a view to its use for metallosplavnyh cathodes."

At the speed of the web resource greatly affect loadable external objects. The most common of them - the image. In this connection it becomes actual size reduction loadable computer graphics (images) to reduce the overall size of the web page. Among the least popular compression algorithms algorithms for lossless coding, because of their low efficiency. However, for a certain class of images through the use of its specific features, it is possible to obtain a much higher compression ratio in lossless coding. The authors proposed a modification of the RLE algorithm, which allows to increase the compression ratio of the images with large areas of solid color.

The technique of the multidimensional analysis of socio-political attitudes is shown on a concrete example. The results of questioning which was carried out in the spring of 2014 among the Rostov region population participating in the work of election commissions of the lower level are the basis for work. In total 144 persons were surveyed. On gender and age distribution, and also on socio-economic indexes our sample was typical for the above mentioned population. About 29 characteristics were used as input parameters in model. They were levels of affective and cognitive perception of the local and central authorities, cognitive estimates by respondents of the relation to various parties of socio-political life, the characteristic of a social portrait of respondents. The affective components were determined by technology of semantic differential, with the subsequent calculation within nonlinear approach. All cognitive components were computed by results of direct poll. Entrance sizes were unwrapped a multidimensional cube on a platform of a package of the multidimensional analysis by IBM Cognos. The functions of respondent’s distribution were computed both for separate components, and for various sections of a cube at the exit of model. The analysis for social and economic, national, confessional, territorial, gender profiles is carried out. It was discovered, in particular, the essential peculiarities in the territorial plan for the main leading factors of a conflictogenity (an affective component of political attitudes). Hierarchy of factors of social tension was created It is shown that the presented technique allows to conduct comprehensive investigation of a socio-political condition of any audience.

The study is based on the results of the survey conducted on the technology of semantic differential in may 2015, RSBIU. The sample consisted of 137 people, and was typical in basic social settings for students. The subjective perception of the political order was calculated under the previously proposed psychosemantic phenomenological model in agent - oriented AnyLogic. Shows the features of the distribution respondents of the levels of perception of local and Central political authorities. At the group statistical level, the difference between the emotional relation to both branches of government are not significant. The average for the study group, the level of perception of 0.04 and 0.1, respectively (with the normalization from -1 to +1). Meanwhile, 52% and 54% of the respondents belong to neutral authorities (level from -0.2 to +0.2), 16% and 14% negative (level < -0,2), and 32% were positive with a level >0,2. Risk group with a strongly negative (level -0,5) with respect to both branches of government is 6% and 8%, respectively. Among this subgroup, it is possible the formation of contentious processes. A comparative analysis with the results of similar studies carried out earlier in may 2014, the last period, the subjective perception was virtually stable. By 2015, there was a slight decrease in the proportion of negative (1% for area and 3% for Russia) configured respondents who have moved to the neutral category. But at the same risk group with a strongly negative attitude to may 2015 increased by 1%.

The proposed method of differentiation of regions on budget performance. It is based on the use of mathematical apparatus in the form of multivariate methods to increase the objectivity of the ratings. Most rating approaches suffer from subjectivity of their construction, as the input information use the expert assessment. As a result , the reliability of the rating evaluation depends on the quality of selection of experts.The use of the complex methods of multivariate analysis led to clarifying the place of each region in the budgetary process of the Federation and allowed us to identify the group of leading actors who have balanced budgets and are leading to revenue for the Federal budget.

The article highlights the problem of global imbalance, which are the result of divergence of economic indicators in different countries, which manifests itself not only in the uneven distribution of natural resources, but also in the accelerated growth of emerging economies with the demographic decline in developed countries. The article discloses significance of state regulation instruments used to come out from a recession phase of the global economic crisis, wherein not only financial support of the stability of financial system, but tax incentives designed to encourage entrepreneurship, as a source of economic growth, are effective. Due to chosen strategy and formulated background, tax system reform in the country, held in conjunction with adjustments to the current tax legislation, serves as the most efficient measure to overcome the crisis and get economy back on track. Implementation of this package plan not only meet the needs of the population and make up for human potential, but also stimulate social production, development of its structure and the pace of modernization.
