Data of the numerical analysis of stress-strain state of beams, plates and folded systems are obtained. Also studied mathematical model of diffusion of heat in the folded system with coefficients depended from temperature. The new classes of the moving of solids in the different problems of dynamics are obtained. The possibility of drift of domain boundary and domain structure in a variable electromagnetic field is shown. The analysis of electromagnetic wave propagation in structures with magnetic and ferroelectric properties taking into account the surface polaritons is carried out. It has been hetted the insurance company probability of ruin and unruin for different models of insurance company's activities. With help of the built three-dimensional model the kinematic structure of the wave fields is described in the unlimited waveguide ojects of hexagonal structure. Waveguide properties of the considered anisotropic materials are investigated Product Description popup.authors popup.nrat_date 2020-04-02 Close
