Today in creation of mathematical models of the stationary plasma thruster (SPT) a certain advance is noticeable, but all these models are based on empirical laws with a possibility of application to concrete type of the engine. The paper considers the possibility of constructing a mathematical model that takes into account the various physical processes taking place in the engine and based ...

The object of the research is a power supply system based on a solar po­wer plant with a non-stationary load on the example of an automatic trading unit (vending machine Coffemar G-546). The aim of the work is an experi­mental study of the influence of solar radiation power dynamics on the volume of ...

This article provides results of the cathode of stationary plasma engine thermal vacuum test with various operating modes simulated, a thermal calculation and the cathode thermal mathematical model verification. Based on the calculations, the cathode thermal model and operating performances were assessed, the most efficient required cathode life time characteristics were selected, which are related to the cathode heater power and operating time with provision ...

Time-depended hydrodynamic model TUBE 7 is used for modeling of field-aligned motions and temperature of polar ionosphere ions taking into account magnetosphere convection. It was shown tube geometry changing have a great influence on basic parameters of polar magnetosphere thermal plasma. 1. Banks P. M., Holzer Т .   Е . The polar wind // J. Geophys. Res. 1968.

The article describes the process of forming the political image of Russia in socio-political media through semiotic inversions. It is claimed that in the modern media discourse, the political image is based on the pre-established ‘rules of the game’. The author holds that historical facts are often replaced by false models of reality in the modern mass media discourse. 1. Люббе Г. Историческая идентичность // Вопросы ...

... doctrine of respect to the moral law as intelligible feeling. This rapprochement allows the latter to play an argumentative role that, by serving as ratio cognoscendi of freedom, is also of epistemic value. Kant’s practical philosophy turns out to be based on a quasi-phenomenological intuitionism of finite reason in which aesthetic elements are of such importance that Wilmans’ assertion of its latent similarity to pure mysticism may be justified.

... space are considered from a point of view of a class of nonlinear Klein — Gordon — Fock equations. It is shown that the Nahm reduction does not work, another, novel choice is proposed and investigated. A quasiclassical quantization of the models is based on Feynmann — Maslov path integral construction and its zeta function representation in terms of a Green function diagonal for an aux­iliary heat equation with an elliptic potential. The natural renormalization use a freedom in vacuum state choice ...

The paper discusses the possibility of physical interpretation of the global ionosphere disturbances during geomagnetic storms, and after them, based on Poincare waves excited in the atmosphere under such conditions. The spectrum of the diurnal variations TEC perturbations were obtained for the midlatitude stations located in the European longitude sector. It is shown that in the spectrum of TEC variations are present harmonics with periods of the relevant standing planetary waves Poincare. Analysis of the latitudinal structure of amplitudes and periods ...
