A reduced model has been developed to describe the time evolution of a discharge in an iron core tokamak, taking into account the nonlinear behavior of the ferromagnetic during the discharge. The calculation of the discharge scenario and program regime in the tokamak is formulated as an inverse problem - the optimal control problem. The methods for solving the problem are compared and the analysis of the correctness and stability of the control problem is carried out. A model of “quasi-optimal” control is proposed, which allows one to take into account real power sources. The discharge scenarios are calculated for the T-15 tokamak with an iron core.

From the standpoint of historical (macro) sociology, the article examines the main directions of transformation of the sources of power identified by the English scientist M. Mann in the realities of post-modern society. The essential characteristics of the four sources of social power, which include ideology, military forces, economics and political characteristics of the organization of states, are considered. The vectors of transformations of these sources of power, contributing to changes in the image of power at the present time, are noted. The interdependence of transformations and the specificity of their manifestation at the institutional level in the political and legal sphere of public life are shown.

Length Effects

Chemical sources of current are investigated as lines with distributed parameters. Analytical expressions are obtained for the voltage and active power values of the source at different distances from the beginning of the cell as well as dependences of the working voltage and active power on the source length. Effects of a reduction in the operating voltage and active power are due to the flow of electric current along the source during operation. The magnitude of these effects depends not only on the length of the source, but also on the ratio of characteristic resistance to the load resistance.<br>
