This paper presents a generalized framework level band pass filter used in the construction of broadband active RC filters. The conditions that determine the potential stability of the broadband link and its parameters. A variant of circuit implementation, in which low parametric sensitivity of Q to passive circuit elements is achieved on the basis of its own compensate small-signal parameters of bipolar transistors parameters amplification. The results of computer simulations have confirmed that the principle of self compensate coupling semiconductor can significantly reduce the sensitivity of the parametric parts of the second-order band-pass filters based on existing low technologies.

  The approximate formulas for determination of planar electromechanical force factor and piezomodule in the disk-form samples without Poisson coefficient evaluation of the smallest (first) frequency equation root are derived. It simplifies procedure of measurements because measurement of frequency of the first overtone isn't required.

  The paper discusses the features of their own circuits and mutual compensation circuitry in a differential stage in CMOS transistors. It is shown that their composition can significantly increase the differential gain in symmetric cascades with a dynamic load, significantly reduce common mode gain and extend the range of operating frequencies. As an example, the evolution of the basic concept of a symmetric stage and the results of its simulation in Cadence Virtuoso.

  The paper presents an analysis of the data obtained as a result of questioning students RGSU in late 2011. The purpose of this study is to measure the level of political tension among the youth after the events of December 2011. 168 young people taken part in this research (men - 53% women - 47%). Age of the respondents - 17 to 19 years. The questionnaire included a subjective assessment of the following levels: participation in the political process, emotional involvement in these processes; comments of these processes, and economic prosperity, social security, life prospects. Revealed a low level of involvement of young people to the political process - 1.40 on average value. The level of emotional involvement in the political process - 2.15. The stable level of comments political processes in the family - 2.17. Received, the average level of economic prosperity and level of social security of students: 2.44 and 2.24. Assessment of life prospects is at a high level - 3.03. It is revealed, values of average all studied parameters at women are higher, than at men. Least a difference in an assessment of level of participation in political processes – 0,1. More differs the assessment of level of social security, the difference makes – 0,69. Thus, level of a relative deprivation among studied audience is low, and if will tension arise in student's group, first of all among men.

This paper presents a method for calculating the spread for the generalized (B, S)-market in case of buying up shares. A brief description of the relevance of tasks, related to the calculation of market value of derivative of assets and concomitant calculations. Substantiate the use of Martingale ideology in studies of financial markets. Describes the essence of the generalized model (B, S)-market in case of buying up shares, as well as the principle of calculating of upper and lower value of the option-call European type.

  Main areas of modern human life and society (education, work, leisure) require the application of complex human ¬ lovecheskih forces and capabilities - physical, psychological, emotional ¬ tional, intellectual, and spiritual. Difficult transition to a market economy in 90 years, affected the fitness and sports motion, ¬. Socio-economic factors and conditions were the prerequisite for the formation of unhealthy motivations some part of students and the students, and this has a negative impact on their health and physical fitness.

Contract organization of project finance allow to reduce the asymmetric information, limiting the possibility of opportunistic actions of each participant. The back-to-back principle, that is underlying for contractual arrangements, increases total project return and provides transfer and split of highest possible number of risks directly to the contractual counterparty, which is best suited and have the most appropriate instruments to cover this risks. Tripartite deeds of project financing can be considered as a cooperative non-zero sum game, which provides compensation in proportion to covered risk and member's contribution (extent of assumed obligations or provided funds). Multiple contracts of project finance initiatives allow to allocate risks pro rata the ability of participants, without reducing the amount of final win of all parties.

  Requirements for methods of diagnosing design increases - they should make it possible to fully assess the performance of buildings, as well as being simple and mobile, to be used during the construction, operation, maintenance and reconstruction. This work is devoted to the realization of experimental and theoretical methods for vibration monitoring of structures and the analysis of the results. The objects of study are the reinforced concrete beams and slabs, and the subject of the study - the methods of vibration diagnostics, the principle of which is to detect changes in the construction of the main dynamic characteristics. Research has shown that damage to the structure can be detected by the methods considered, using a relatively small number of monitoring points and subject to change only the fundamental mode of vibration.
