The Temetos platform is designed to conduct computational experiments at all stages of analysis and study of continuum mechanics models. A module has been developed to study the stress–strain state of a system of bodies with allowance for inelastic strains and contact interaction. It was used to analyze a fuel element that included up to 100 fuel pellets and a shell. The platform's solvers are applied to astrophysics problems. Models of the formation of accretion disks in binary star systems that allow the interpretation of observation results are constructed. [ABSTRACT FROM AUTHOR]

The temperature mode of a metal contact upon transition to a hybrid and further on to a plasma one has been studied. Spatial (three-dimensional) mathematical modeling confirmed the existence of a dependable metal contact before melting of the anchor material and transition to an arc mode of passage of the current after the onset of boiling. The possibility of destruction of the accelerated body during the acceleration time has been investigated. [ABSTRACT FROM AUTHOR]

We investigated fluorescence and fluorescence excitation spectra of five substituted diphenylpolyenes with the number of double bonds in the chain n = 2 or n = 3 and substituents NO2, N(CH3)2, and NH2 in different media (toluene and n octane) at low (77 and 4.2 K) temperatures. The duration of fluorescence (τ) and the quantum yield of fluorescence (ϕ) of the four compounds investigated were measured at room temperature. The influence of the electron donor acceptor interaction in one of the compounds on its spectral luminescent properties has been analyzed. [ABSTRACT FROM AUTHOR]

Methods of numerical modeling of an electromagnetic field in electrodynamic launchers of the railgun type in the presence of magnetization turns have been proposed. Results of employment of different methods to model the electromagnetic field in a modular augmented staged electromagnetic launcher (MASEL) have been presented; a comparison of the results of simulation and full-scale experiments has been made. The issue of the dependence of the electromagnetic field on the configuration of magnetization turns has been investigated. [ABSTRACT FROM AUTHOR]
