Data preparation for computer simulation of cross-wedge rolling (CWR) process based on ANSYS/LS-DYNA finite element code is considered in the article. In order to automate the process of developing CWR models and performing their finite element analysis, specialized software (PSPD) was developed. This software provides creation of a finite element (FE) model of the rolling process considering the specifics of CWR technological processes and different aspects of the application of the finite element methods (FEM) in the metal-forming processing. PSPD interacts with the base system through APDL scripts, that describe individual sequences of actions for preparing the FE model and choosing solver parameters to run the task. PSPD provides a graphical user interface (GUI) which allows users to enter necessary data for generating APDL scripts, the model builds automatically in ANSYS in batch mode when scripts are run. Also, PSPD provides preparation of the FE model for solver and provides managing the calculation process. In addition to describing the functionality and features of the program and its GUI, the article provides techniques and methods of FE model preparation for computer analysis using the developed software as well as the main steps of creating FE model in ANSYS/LS-DYNA, which are automated in PSPD. PSPD can significantly reduce the demand for knowledge in the field of computer simulation to the engineers engaged in the development of tools and technical processes for rolling, it allows quickly creating and modifying FE models, performing CWR research for a variety of input data of process technology and solver parameters.

Competitive strength of the Russian securities market (RSM) depends on its participation in solution of important economic problems. RMS plays a positive role in the privatization process in Russia and in forming effective corporate governance models. The importance of RMS in attracting investments is increasing. However RMS savings function is its essential weakness. The growth of the RSM competitive strength requires complex measures in the field of legislative activity and economic policy.

This book is devoted to the study of dynamical models of decentralized economic systems. The models considered are based on the Leontief simple dynamic model with various mechanisms for decentralized planning and management. Branches of the economic system are treated as fully independent economic agents that plan their work according to their own purposes. It is shown that the lack of coordination between economic agents leads to a limit cycle for some economic indicators. Conversely, the exchange of information between the economic agents enables a move toward balanced growth. These results are generalized for the model with dynamics of the productive assets and for the model with the final consumption. The analysis also considers a problem of endogenous technological progress in a decentralized economy. The appendix includes a short review of non-negative matrices. The book offers a valuable resource for mathematical economists and graduate students specializing in mathematical economics.

The purpose of the article is to analyze matter, and more specifi cally the elements, which were understood in a similar way in diff erent cultures. The following basic qualities of the elements are revealed: water is the source of all being and vitality, earth is stability and corporality, air is space, as well as the "breathing" of the spirit, fi re is
the guiding and purifying principle. Fire, especially in its most refi ned manifestation of light, and also air act as a pair of «upper» celestial, active elements. Earth and water follow the «upper» elements and complement them. «Axis of the world» connects the earth and sky, uniting all the elements. As its manifestations, which set the vertical and center the cosmos, are the world mountain and tree, as well as fi re, such as the «center of the universe», Hestia of the Pythagoreans. Natural numbers such as 2, 3, 4 set the structure and dynamics of the development of nature and man. In mythopoetic perception, the realistic setting of everyday consciousness is inextricably woven into the holistic panpsychist symbolic picture of the world. It is concluded that the archetypal mythopoetic ideas about the elements act as a source of meaning for philosophical knowledge: for the philosophy of art, anthropology and ontology.

Relevance. The information sphere in the modern world has become the main system-forming factor of all spheres of public life. In recent years, the media has undergone a significant transformation. The change in the role and place of Russia in the world has intensified the struggle for a dominant role in the information space of our time, in which our country has become the main object of information wars. In this regard, the role of military mass media, which ensure the information security of Russia, form a positive image of the Russian army and strengthen its authority, is significantly increasing.The purpose is on the basis of scientific analysis to determine the role and place of military mass media in the conditions of increasing information confrontation of interested parties.Objectives: conceptually substantiate the use of socio-cultural methodology in the study of the nature and consequences of information wars and conflicts and outline the main directions for improving the Russian military mass media.Methodology. Socio-cultural methodology is defined as the initial theoretical matrix in explaining the role of military mass media in information wars that are generated by conflicts as a result of institutional, socio-political, socio-economic, socio-cultural and technological changes.Results. The main results of the study are defined as follows: the conceptual apparatus is characterized, which allows to reveal the role and place of military media in the information space of social communications; the current structure of the Russian military mass media, their tasks and functions are presented and the main ways of their improvement in the transformational dynamics of the information space are outlined.Conclusions. Military mass media is a fairly effective tool for information security of Russia. Maintaining a positive image of the army and navy in the interests of ensuring Russia's security is one of the priority areas of activity at all levels of civil and military and civil administration.
