The paper discusses the features of method of extension of circuit’s operating frequency range of the source and the classical emitter voltage follower (VF). The features of this method based on the effect of the mutual compensation of the parasitic impedances are considered. Problem of improving operation speed of VF with output capacitance and reducing the time of establishment of transient at pulsed input voltage are discussed.
The simulation results of VF in Cadence on model of SiGe integrated transistors are given. This shows that with capacitive load high-frequency cutoff, the time of establishment of transient and the slew rate improved to tens - hundreds of times. 
The results of investigate complement of methods of improving operation speed of the classical stage with a common drain and common collector.

"This article describes modeling of uniform system of design and technological preparation and production. The mathematical model is based on base of the theory of probability, the theory of mass service and mathematical statistics. Its basis is markovsky casual process. If the stream of events at the enterprise is stationary, without a consequence and ordinary, this process is called the elementary. The average size of a flow of information of each service is determined by the law of distribution of Erlanga, the stream density is determined by the enterprise, and production transition from a condition to a condition of shops and productions is estimated. When modeling a flow of information on movement of information and details at the enterprise classification of divisions was offered. After the analysis of their activity and a flow of information, details and documents the state graph of uniform system of design and technological preparation and production is constructed. Transitions were thus described and factors are appropriated. For each condition of system of a state graph limiting probabilities of conditions were calculated and Kolmogorov's equations are worked out. At integration of data of systems of the equations the probability of conditions of activity of divisions and production as time functions during every moment of time is defined."

This paper describes application of different criteria for estimating parameters of traffic simulation. For comparison following methods were used: statistical methods for comparison of a flow and speed in control points of a network - analysis of variance (ANOVA), Theil's U-statistics; relationships between flow, density and speed; relationships between trip time and stop time with using two-fluid models of traffic flow. For this aim we also used concept of meta-model. In order to implement this method we need on the first step to create separately relationship between traffic flow parameters for observation and simulation data and then to estimate combined model. The paper included results of calculation

"The paper proposes a method of use of the accumulated surplus of solar water heating installation, the major element of which is the solar collector for heating of greenhouses. The heat energy, which was preserved in the battery for the summer months, can be used for heating of greenhouses in the autumn and winter months. The proposed method will significantly increase the efficiency of the solar collector and reduce the term of recoupment. This development will be relevant for the individual dwelling houses, with garden plots sufficient to build greenhouses there. The use of ""Energy - Effective"" greenhouses combined with solar water heating unit, significantly reduces the cost of electricity and heating. The use of low-grade thermal energy from the sun and soil is the main direction of development of energy-saving technology of housing and communal services. "
