Abstract
The absence of a method for strength calculation of a shaft of wells’ sinker, considering its structural features, significantly complicates the constructor’s work in determining essential cross-sections of a shaft, providing its reliable, no-failure operation during the whole life cycle. The article provides the scheme of loading a rolling working element in a well, the scheme of a load transferring from rollers to the shaft’s core using off-center bushing. The authors of the article have also determined the influence of these bushings on load distribution along the core.

Abstract
This article discusses various efficiency criteria for diagnosis of transport and technological machines. As the main criterion it is proposed to use the reliability of technical diagnostics, which can be evaluated by the probability of a correct diagnosis or error. The errors in turn are subdivided into errors of the first and second kind, which have statistical nature and depend on various factors.

Abstract
The results of the test piece of precast reinforced concrete slab of natural products. The experiment was conducted in accordance with the recommendations for the calculation of transoms frame type series 1.020-1/83, taking into account the joint work with the flooring. We checked the impact of flooring on beams with different-tions combining vertical and horizontal loads. The effectiveness of the interaction was evaluated by comparing the test results of the twin crossbars composed of overlapping and inde-pendent scheme. It was found that the work of the dowel connections is not sufficiently reliable, and the influence-of the horizontal load is virtually absent.

Abstract
This paper presents a general approach to the calculation of beam spans wood concrete bridge by taking into account physical nonlinearity and different resistance materials as well as the actual loading conditions. In general, it is assumed that a part of the concrete, and the wooden part represent a layered substructure made of different types of concrete and wood. A method for solving systems of nonlinear equations resolution, which has significant advantages in comparison with the iterative methods. Examples of calculations showing the possibility of a significant increase, both strength and rigidity of the structure due to a combination of different types of wood in the cross section. The important feature of the layered construction work under load, namely the possibility of latent forms of destruction when the initial breakdown occurs in the inner layers of the cross-section.

Abstract
This article is devoted to the research developed at the Department of bridge span structures with composite girders made of logs, united to work together through the deaf cylindrical pegs embedded in steel plates as well as the development of methods of their calculation and perfection of structural and technological forms of superstructures. The peculiarity of the considered nog compounds is rigid clamping nogs in the coupled steel linings. By virtue of tough embedment of nogs in the seam coupling should expect an increase in carrying capacity of the connection due to the bending stiffness of the nog and due to local buckling under the wood nog. To account for the compliance of the considered nog connection a new method of calculation is developed. Offered research shows effectiveness of the decisions.

Abstract
The problem of estimating the norm of the distance between the two closed smooth curves for pattern recognition is considered. Diffeomorphic transformation curves based on the model of large deformations is described. For estimating of the norm of the distance between two closed curves is formed the functional corresponding normalized distance between the two curves, and the equation of evolution diffeomorphic transformations. An algorithm for solving the equation of diffeomorphic transformation is proposed, built on the basis of PSO, which can significantly reduce the number of computing operations, compared with gradient methods for solving. The developed algorithms can be used in bioinformatics and biometrics systems, classification of images and objects, machine vision systems, for pattern recognition and object tracking systems.
