The reactions 12С(γ,n)3Не2a and 16O(γ,n)3He3a is investigated by a method that employs a diffusion chamber placed in a magnetic field and irradiated by a beam of bremsstrahlung photons with an end-point energy of 150 MeV. In the excitation curve

We state an optimal control problem for a class of dynamical systems whose nonlinear objects can be represented as objects with linear structure and state-dependent parameters. The linearity of the structure of the transformed nonlinear system and th

The article deals with the problem of control synthesis for nonlinear dynamical systems represented by mathematical models with a linear structure and state-dependent parameters (SDC-model). The value that the Hamiltonian takes for suboptimal control

Properties of one-dimensional spatially periodic metal structures formed by a dielectric lattice covered by gold and permalloy films are studied by optical and magnetooptical spectroscopy techniques. It is shown that these structures reveal the excit

The microstructure of a 1417M alloy after magnetohydrodynamic (MHD) treatment has been studied. An electric field induced in the aluminum alloy melt is shown to cause electric transfer and to homogenize its structure. During the formation of an ingot

In this paper, we consider the issue of synthesizing optimal control of nonlinear dynamic systems in case of a problem with an unspecified time of the transition process. To solve this problem, an algorithmic method for constructing a suboptimal cont
