The compare the durability of the existing ball bearings (SHO) with the polymer homogeneous element with the durability of the modified supports, a cell model with the averaged placement of the modifier in SHO substrate and a model for bringing the multilayer sho body to the equivalent single-layer one are constructed; calculations of contact pressure, contact deformations and stresses are performed. The calculation takes into account the rheological and physico-chemical properties of the components of SHO substrate and modifier, the influence of the environment. As a result of calculations, it was found that at all points of the contour the material experiences a biaxial plane two-dimensional stress state, called pure shear with the presence of shear stresses. The most intense point of danger is the point lying in the center of the platform of contact of details.

Up to now, the problem of recognizing printed characters of different fonts with high speed and reliability is not solved. The team of authors carried out research of images of printed characters of different fonts for the purpose of revealing the signs necessary and sufficient for recognition of signs by a computer. These features were a certain combination of directions, formed by elements of the contours of signs. According to the developed program for the computer, the image of each printed character stored in the computer's memory device was scaled up, uncharacteristic signs of signs, certain defects were eliminated and the contour of the sign was highlighted. The contour was represented in the form of a sequence of definite directions formed by its elements. All printed characters of the Russian alphabet of different fonts were recognized by a certain technique, despite the different types of printed fonts, for certain possible defects.

The article is devoted to the problem of using artificial neural networks as one of the methods of data mining (intellectual data analysis) for classifying the competencies of university students when determining the educational specialization. It describes the complexity of the process of selecting specialization and the associated negative consequences, as well as an approach to solving the given problem using software classification tools.

The article considers theoretical bases of technological process for modified wood production for sleepers manufacture. Currently, sleepers are made mainly of natural softwoods, the stock of which is severely limited. In addition, sleepers made of natural wood have short wear-life. In this connection, there is a need to create a new high-tech resource-saving production of railway sleepers from modified wood by impregnating it with antiseptic and stabilizer compounds and carrying out thermal and mechanical modification of wood. For this purpose, a systematic analysis of physical phenomena underlying the technological operations has been performed and on the basis of which the curves for workpiece heating along cross-section in an oily liquid based on similarity criteria has been theoretically calculated, and on the basis of the physical phenomena of heat and mass transfer the duration of workpieces drying has been calculated. Methods of impregnation, loading and depressurization during pressing have been got. Based on system analysis of physical phenomena and performed calculations, structure and regimes of technological process for modified wood manufacturing have been developed.

The purpose of the study is to develop a software – oriented algorithm for calculating flat rod systems with variable length modulus of elasticity. The object of study – a flat rod system, located in a single load, the elements of which are interfaced at the nodes rigidly or pivotally; the shape of the axes and the conditions of the support are set. A special finite element is developed on the basis of the finite element method in the form of a mixed method. To calculate the elements of the response matrix and the vector of freight coefficients, a numerical integration procedure is used. Examples of calculation of cantilever rods in two variants are given: with a variable length modulus of elasticity; and a rod having three, five and seven sections along the length made of different materials. The comparison with the results of other authors is given. A flat frame of four finite elements with variable modulus of elasticity is calculated. The results of solving the examples indicate the correct operation of the proposed algorithm. It is shown that the parameters of the stress-strain state of the structure can be adjusted by changing the properties of the material.

The paper deals with statically determinate and statically indeterminate reinforced beams of a rectangular cross-section of bimodule material loaded with a uniformly distributed load. Since for heterogeneous materials, the elastic modulus for tension and compression are different, the work aimed to study the influence of different boundary conditions in statically indeterminate beams on SSS. It is shown that the magnitude of the maximum normal stresses is less than the stresses found without taking into account the bimodule nature of the beam material, both in statically determinate and in statically indeterminate beams. The maximum normal stress and maximum deflection decrease with the transition to a statically indeterminate beam from a similarly statically determined beam by replacing the supports. The method used in work makes it possible to clarify the calculation of strength and rigidity, taking into account the bimodule nature of the material of the reinforced beams, and also to select the optimal fastening of the beams that ensure the bearing capacity of the structure with material saving.
