The article presents results of testing models of piles with different longitudinal shapes under the action of a static pulling load, performed in laboratory conditions. The article reveals resistance of the pyramidal-prismatic piles can be either more or less than the resistance of the prismatic and pyramidal piles. It was found that an increase in the length of the pyramidal part of the pile, as well as the size of its cross-section at the top, affect the resistance of the pile to pull-out load. So, the resistance of these piles is 1.28-1.85 times higher than the resistance of a prismatic pile with a section size of 20×20 cm, and 8-36% lower than the resistance of a prismatic pile with a section size of 30×30 cm and a pyramidal pile (with a top section size of 30×30 cm and at the bottom - 20×20 cm). Correlation dependencies are obtained to assess the stability of pyramidal-prismatic piles in relation to the bearing capacity of piles with traditional longitudinal section shape (prismatic and pyramidal piles).

: Traditionally, the elastic response of soils has been assumed to be isotropic. Natural soils are, however, more likely to exhibit anisotropic response. For example, sedimentary soils, which are typically deposited under gravity, possess different properties in the direction of deposition as opposed to the planes normal to this direction. This paper synthesizes several key issues related to anisotropic elastic material idealizations for soils. Emphasis is placed on transversely isotropic (“cross-anisotropic”) elastic material idealizations. Abstract: The computational (numerical) diameter is used to completely solve the problem of approximate differentiation of a function given inexact information in the form of an arbitrary finite set of trigonometric Fourier coefficients.

This article presents the results of research funded by the Committee of Science of the Ministry of Science and Higher Education of the Republic of Kazakhstan (grant № AP14972884 "Increasing wear resistance of metal-cutting tools by the method of lapping"). There was investigated the state of the metal-cutting tools' wear problem in the conditions of machine-building enterprises of the Republic of Kazakhstan (RK). It is revealed that metal-cutting tools do not always endure the durability period according to the standards and are exposed to premature wear of cutting edges, breakage, and chipping. The factors affecting the wear resistance of metal-cutting tools and the existing possibilities for their improvement are also studied. The article proposes the method of pretreating cutting tools in order to improve the wear resistance and durability of metal-cutting tools under the conditions of domestic machine-building industries. The formation of secondary structures on the working surfaces of the tools, which is one of the manifestations of the fundamental law - structural adaptability was studied on the basis of the results of the analysis of previously conducted works.

Particularly difficult in this problem is the search for effective solutions that ensure an increase in the resource of working organs, including soil-cutting details.

This article presents the results of a study by foreign scientists on the study of the technological feasibility of the method of friction welding of dissimilar materials. As well as information about the research work of the authors on the creation of a resource-saving, universal and affordable technology for friction welding of dissimilar materials for domestic engineering industries. The results of the study of the work of foreign scientists showed that the method of friction welding of dissimilar materials is relevant and has a wide technological capability. It was also found that there was not used method of friction welding of dissimilar materials in the conditions of domestic engineering industries. The article presents alleged causes of this state of the problem. Considering all the shortcomings and factors identified during the study of existing methods of friction welding of dissimilar materials, the authors carried out scientific research aimed at creating a new method of friction welding of dissimilar materials. To implement the friction welding method, a design of a special device was developed and a prototype was made for experimental studies. The article considers processes of friction welding of reinforcing bars of different diameters. It is reported that the connected reinforcing bars have passed tensile and rupture tests in laboratory conditions and in a certified test center, the results of which showed a high strength of the connection. The rupture of the rods did not occur in the welds but in the base metal.

We have performed preliminary work on topological analysis of audio and text data for unsupervised speech processing. The work assumes that phoneme frequencies and contextual relationships are similar in the acoustic and text domains for the same language. Accordingly, this allowed the creation of a mapping between these spaces that considers their geometric structure. As a first step, generative methods based on variational autoencoders were chosen to map audio and text data into two latent vector spaces. In the next stage, persistent homology methods are used to analyze the topological structure of two spaces. Although the results obtained support the idea of the similarity of the two spaces, further research is needed to correctly map acoustic and text spaces, as well as to evaluate the real effect of including topological information in the autoencoder training process.
