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.

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.

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.

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.

The article deals with the integration of a three-dimensional model of a parametric architecture object created by Autodesk Revit and its finite element model. The features of IFC formatting expand the possibilities of presenting design data for solving problems of integration information and computational models. The advantages and disadvantages of this approach to the modeling of unique high-rise buildings, the architectural solution of which is a complex geometric surface, are illustrated. The resulting finite element models allowed us to perform a static calculation and analyze the characteristic movements of the frame elements of a unique building. The practical significance of the presented research results lies in the possibility of using a parametric architecture for designing objects using BIM with subsequent analysis of the stress-strain state of the frame of a building or structure.

The problem of transmitting an image in a transmitter-receiver system over a noisy data transmission channel in JPEG 2000 and JPWL format under conditions of a previously unknown and varying intensity of noise is considered. This task is considered for the conditions of the IP network. The article aims to build methods for estimating the intensity of noise by the JPWL decoding results in the receiver and dynamically adapting the parameters of the JPWL transmitter to the current assessment of the noise intensity, ensuring the highest quality of the decoded image with the shortest length of the transmitted encoded stream. An experimental study of the relationship between the parameters of JPWL, the intensity of noise and the quality of the decoded image was carried out. It is shown that for any JPWL parameter there is a region of one-to-one correspondence between the percentage of fully recovered tiles and the probability of losing a network packet. A technique for estimating the intensity of noise by the decoding results of a single image is described. This technique can be expanded to use the results of decoding a series of images.
