Abstract
There are offered methods of faults reconstruction in stratified composites - stratifications (the interface flaws). Inverse geometrical problems of reconstruction of flaws are reduced to a solution of sequence of systems of the BIE obtained on the basis of reciprocity theorem of operations at established oscillations of expert samples. Solution BIE will be carried out on the basis of a combination of FEM, a method of BEM and a method of a regularization of A.N.Tihonov. As the additional information for a solution of inverse problems the field of displacement measured on a part of exterior boundary of a skew field, free from mechanical stress. Numerical examples of identification of stratifications and ruptures surveyed within the framework of a flat problem of theory of elasticity.

Abstract
The parameters of the imitative model of multilayer conductive ferromagnetic media to achieve the optimal precision of modeling are determined. The experimental investigation of the distribution of physicomechanical and electromagnetic properties along the thickness of the sample have been carried out. The standard epures of these properties were determined. The parameters of the imitative model of the multilayer conductive ferromagnetic media to achieve the optimal precision of modeling are determined.

Abstract
In article the mathematical model of formation of noise of the stand of vibroshock hardening of longerons of helicopters is resulted. Power methods speeds of fluctuations of separate subsystems and bearing system as a whole pay off. Dependences of vibrating capacity entered from a working environment in walls of containers are received that essentially specifies the theory of calculation of noise of the similar equipment.
THE DYNAMIC PROPERTIES OF THE CENTRIFUGAL DEVICE FOR THE SUPERFICIAL ENTERING OF MINERAL FERTILIZERS
224-230 256
Abstract
The research of dynamic properties of the centrifugal devices for distribution of mineral fertilizers on a field surface adaptably to substantiation of the admissions on fluctuation of the process parameter. The admissions on proportionality of giving of the fertilizers on a distributing device, an average quadratic inclination of an angle of throwing and a range of casting are recommended to set the non-uniformity of distribution of the fertilizers on a field. The probable model of the system is represented by the consecutive connection of a link of constant retardation and two non-periodic links. The link characteristics are determined by the numeric modeling.

Abstract
The welded joints of the type of rod parts and body part are applied in machine-building and building. To get such joints for nonferrous metals and alloys by arc welding is extremely difficult. For these purposes especially for welding large sized parts it would be advisable to use electro percussive welding with magnetic pulsed drive it combines thermal and forced influence on welded parts due to the condenser batteries charges on working tool inductor.

Abstract
Results of theoretical definition of coordinates of a cog side having in normal cross-section the elliptic profile are presented. Equations connecting angular and linear dimensions of cogs in face and normal cross-sections are obtained. The offered technique is usable for a determination of coordinates of the profile circumscribed by any plane curve of the second order.

Abstract
Huge amount of similar informational systems available today inevitably causes the problem of 'the right choice'. There are plenty of ways to estimate product quality today, however most of them either gives subjective results or requires plenty of computations to be made by user. An alternate way of comparing two or more infromational systems by user-defined quality factors is described in the following article.

Abstract
A method of reducing the amplitude of fluctuations in moving body of the industrial robot, gripping device in positioning mode. A feature of the method is to use two currents dynamic slowdown an asynchronous motor, running on a «autonomous voltage inverter - induction motor» in the frequency control. Program forming torque on the shaft of asynchronous motor through the mutual rotation vectors of the magnetic field of stator and rotor taking into account the amplitude and phase fluctuations in moving body of the industrial robot allow more accurate positioning gripping device in the performance of the transport and manufacturing operations.

Abstract
Philosophical problems of social sciences and humanities in the aspect of person- 's subjectivity, life world, forming of values orientation, strategies of life cognition, self creation of person are studied in the article. It's shown that developing of synergetic problems results in reinterpreting of man's situation in the structure of cognition and practical activities. It enables to newly analyze social and humanities cognition.
