It is well known that, in the context of General Relativity, some spacetimes, when described by a congruence of comoving observers, may consist of a distribution of a perfect (non–dissipative) fluid, whereas the same spacetime as seen by a “tilted” (Loren... see more

The paper discusses the similarity between dissipative generation and superradiance regimes for systems of excited quantum emitters placed in an open cavity. In the case of the existence of a resonator field due to reflections from the ends of the system,... see more

The instability of a freely falling jet of liquid in air taking into account the viscosity of the contacting media is considered. In neglecting the viscosities of both media, instability was studied by Rayleigh and Plateau. They showed that instability de... see more

In this paper, a reflex charger with zero-voltage-switching (ZVS) and non-dissipative cells for photovoltaic (PV) energy conversion is presented. The proposed reflex charger has the following advantages: (1) A ZVS cell is incorporated to reduce the switch... see more

Nonlinear oscillations of the magnetized non-uniform collisional plasma are studied. Basic nonlinear equation is got for waves and regularization of the theory of perturbation is considered. It consists in the inclusion of dissipative terms into normal fu... see more

This paper reports the results of experimental studies into determining mechanical properties (elastic and dissipative) at the shear of the material of a pressure fire hose of the "T" type with the internal diameter of 77 mm using torsion tests. Duri... see more

Formulation of the problem. The problem of the behavior of the liquid phase on the crystal - liquid boundary under non-equilibrium crystallization is very important. Recent studies indicate the need to build models allowing for the conditions hypothermia ... see more

Experimental research into determining the mechanical properties (elastic and dissipative) of the pressure fire hose of type «T» with an inner diameter of 66 mm under conditions of static load were presented. The experiment was conducted on the experiment... see more

Variations in the disturbance depth were measured across four open mesotidal beaches on the Gulf of Cadiz coast of Spain during single tidal cycles, using rods and plugs of marked beach sands inserted in the foreshore. The studied beaches show a wide rang... see more
