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.

Mathematic model considers the geometrical and physical nonlinearity, the adaptability of creep flow. Arc work is accounted for by the method of constructive anisotropy, but with due regard for shear and torsion rigidity. In solving physically nonlinear problems, secant modulus is defined directly from the «σ-ε» curve, found experimentally. Mathematic model is written in the form of functional of total deformation energy. This model can be used for comprehensive analysis of the stability of reinforced shells of revolution.

Article is devoted to transformation of the concept of a risk management to the tasks of management by development of city territorial systems. The generalized schematic structure of risk management of development of the urbanized territories is considered. Need of the accounting of economic, ecological and social consequences of administrative decisions in the course of realization of strategy of development of territorial systems is substantiated. The mechanism and algorithm of formation of predictive integratedestimateof quality social-ecological-economic system as a result of realization of strategy of the development is offered, allowing essentially to reduce quantity of analyzed options of operating influence.
