In presented article rank criteria for the statistical analysis of two selections are considered. These criteria check statistical hypotheses. Three groups of rank criteria were considered: about equality of the central tendencies, scopes of a variation and distribution laws. Researches were conducted on data on exchange rates in two next days in nine banks. Correctness of criteria was estimated proceeding from an US dollar exchange rate established by the Central bank of Russia. To these data rank criteria of Wilcoxon, Van der Waerden, Kolmogorov-Smirnov and others were applied rubbed. Coinciding values of two selections were estimated by means of a method of an average rank. For all examples rank criteria gave the correct assumptions of equality of two selections.

The article deals with the analysis of the application of the method of NS. Strelets for the static calculation of construction structures. It is proposed on the basis of the probabilistic-statistical method NS. Streletsky instead of the normal laws for operating voltages and strength apply laws with a shift, in particular, the law of the Weibull with three parameters and the Fisher-Тippet. It is proposed to make the transition to the parameters of the totality of the finite volume that will allow to increase the accuracy of calculation of probability of failure-free operation and the proposed probabilistic safety, and also to optimize the probability of trouble-free operation of construction structures

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.

Are considered method of reducing one of the most essential components of the voltage offset Uvo operational amplifiers (op-amp), executed on classical architecture with current mirrors, which is linked to the change current gain of base (β) bipolar transistors in conditions of temperature and radiation effects.
To solve this problem in the basic architecture of op-amp is entered special corrective multipole, which will provide low-current asymmetry in coordination of input differential stage (DS). The method is applicable to op-amp, which is inexpedient to make any adjustments to the original structure of the DS.
The analytical expressions determining basic parameters the compensation circuits Uvo, and also shows the tabular data that simplify the choice of standard functional components of precision op-amps.

Seed damage has a negative impact on the subsequent development of the plant, its yield, and generally on the economic efficiency of grain production. Main percentage of the grains injury occurs in the post-harvest processes, particularly in the grain cleaning. One way of solving this aim is reducing of macro and micro damage of seeds by using of the new polymeric materials. Researches have been conducted to reduce the micro and macro of injury barley seeds (feed material) through the use of new sieves made of polymeric materials UHMW PE for agricultural machinery.
