  • Ultrasonic in plasma-electrolyte process application methodology

    This article describes the combined method of plasma-electrolyte processing and subsequent ultrasound imaging of medical needles created from steel grade 12H18N9T. A functional diagram of an installation for medical needles plasma-electrolyte treatment is presented. A device for ultrasound diagnostics of microrelief in the obtained material is described. The actual task of ultrasound medical research is the quality of the processed tip. One of the ways to obtain deformation at the end of the needle is the electrolyte-plasma discharge method at the anode of a given material. In the course of the study, previously obtained results were confirmed, indicating that the plasma electrolyte process was caused by a fivefold or more excess of the cathode area relative to the anode area Sк≥5Sа. A study was conducted of plasma-electrolytic processing of steel grade 12H18N9T using anodic electrolyte. It is shown that in the plasma formation area occurrence around the anode, the current-voltage characteristic is practically independent of the electrolyte concentration. The patterns of formation of the depth of the hole at the end of the needle, determined by the process of melting the surface layer of the anode, which requires a uniform input of heat over a unit of time. The depth of the well and the wavelength of ultrasound are shown. It is necessary to apply roughness (holes) with a size of 10-1000 microns at different angles relative to the axis of the tube with a tip. On the research basis, a unique device «KLYON-1» was created, which performs the material processing and its control by means of ultrasonic radiation.

    The development of modern technology makes increasingly stringent requirements for materials, and improving the reliability and durability is an urgent task for many industries. One of the most important elements of the automatic coupling device of the car is the absorbing device.

  • Radiowave propagation hybrid model for rough terrain, wooded and urban areas

    The article focuses on radiowave propagation in complex conditions combining rough terrain with woodland or urban areas. The estimation of influence of all these factors on signal attenuation may be challenging. Consequently there are no propagation models for such environment for distances up to several kilometers. However by approximating the experimental data on radio wave attenuation it is possible to develop empirical propagation models for specific cases. The authors carried out a series of experiments to measure the level of radio signal at a given distance from the source. Based on the experimental results a hybrid model for rough terrain, wooded and urban areas for ground communications systems was developed.

  • Mythological constructions in the socio-political habitus of Russians as a project-models of permanent forms of political relations

    The article presents the author's theoretical and methodological construct of the study of socio-political behavior of the social actor. The developed construct is based on the concept of habitus introduced into the scientific discourse by Pierre Bourdieu. The socio-political habitus in this article is understood as interiorized patterns of perception, interpretation, evaluation and action in the socio-political space, which are constantly being refined and completed under the influence of everyday social practices. Denoted epistemological problem of combining the contradictory nature of the conduct and integrity of the habitus. As a solution to the problem, such a property of habitus as hierarchy is considered. It is assumed that in the deep structures of habitus there are integral models of social dynamics, which are reproduced in socio-political relations by spontaneous coordination of social practices of many social actors. However, each social actor represents a single element of the complex model. Such social dynamic models in this article are denoted by the term "myth". On the basis of the presented theoretical model, the solution of applied problems in the management of socio-political behavior is proposed. At the same time, the authors proceed from the fact that mythological complexes in the structure of the habitus can not be eradicated or replaced, but can be overbuilt.

  • Influence of Photogrammetric and internal refractions on definition of linear elements of external orientation

    The object of research in the presented work is the influence of photogrammetric and internal refractions on the definition of linear elements of external orientation. At the conclusion of photogrammetry formulas it is supposed that the light beam is a straight line from the object to the center of the projection. In fact a beam of light passing through the atmosphere layers of various density is bent. This bend is called refraction. The determination of the elements of internal and external orientation and corrections to the coordinates of the points of the image by control points is based upon a decision of the spatial photogrammetric back-sight. Compared to the rigorous method a simpler method for solving the spatial photogrammetric back-sight is suggested which validity check performed by the modeling method showed its rather high accuracy.

  • Models of formation of integration projects on the basis of growth points of subjects of the southern Federal district

    Research of models of formation of integration projects on the basis of points of growth reveals a number of important aspects related to the stages and management of their implementation. The focus on the formation and support of growth points essentially excludes the use of unary models in the planning and implementation of projects within the framework of national programs. In order to overcome the limitations imposed by this type of project, various integrative mechanisms are proposed. The peculiarity of the considered binary models describing the integration mechanisms is the preservation of the basic cycle of the project points of growth within the national program. However, the introduction of additional contours in the model with growth accelerators, with related or integrated projects, as well as attracted resources can reduce the risks caused by high rates of development and innovation issues. The integration potential of the binary model with the project of the growth point in the basic circuit generates a dynamic competitive advantage, i.e. a sustainable, increasing advantage over time that is not related to the amount of initial funding. This advantage generates a powerful growth cycle that can provide a significant increase in profitability over a long period of time. The integrative nature of growth point projects should be envisaged already at the planning stage of national programmes with appropriate monitoring and funding instruments.
