The entropy of the Universe is calculated within the Einstein and Logunov concepts. It is shown that the entropies of the Universe calculated within the foregoing concepts coincide at the Beginning and at the present time. © 2012 Springer Science+Business Media, Inc. Source

The finite cluster model (FCM)-based homogenization scheme has been formulated in terms of the dipole moments of the representative volume element (RVE) of actual composite and equivalent inclusion. Provided the interactions between the inclusions were taken into account, this scheme is asymptotically exact in the sense that the effective properties converge to its exact value with increasing RVE size and thus can be regarded as a rigorous method of micromechanics. To demonstrate its potential, the conductivity problem for a composite with non-randomly oriented elliptic inclusions is considered. The convergence of the solution is illustrated, and an effect of the microstructure including the orientation factor on the effective conductivity of the composite has been explored. The methodological issues of FCM application are discussed including an appropriate shape of the composite cluster and equivalent inclusion. The practical importance of the FCM consists in its direct applicability to the image of the microstructure obtained by the instrumental methods which makes it a convenient tool for estimating the effective properties of a composite in situ. © 2015, Springer-Verlag Wien.

The article examines a problem of searching for new energy-efficient technological solutions in alumina production, which is characterized by nonlinearity, inertia and closedness. It suggests a method to solve this problem on the basis of modeling of the production process and development of the optimizing function based on production cost and obtaining values of the process variables. © 2015 IEEE.

The parameters of six resonances of the isobar model for η′-meson photoproduction were fitted to experimental differential cross sections for the reaction γπ → η′p that weremeasured by the CLAS-2009 and CBELSA/TAPS Collaborations (Mainz, Germany). It was shown that, in the photon energy region from the reaction threshold to 3700MeV, a good description of the experimental cross sections was attained by taking into account the contributions of high-angular-momenta heavy resonances alone. © 2013 Pleiades Publishing, Ltd.

An atomic model of the Big Bang has been developed on the basis of quantum geometrodynamics with a nonzero Hamiltonian and on the concept of gravitation developed by Logunov asymptotically combined with the Gliner's idea of a material interpretation of the cosmological constant. The Lemaître primordial atom in superpace-time, whose spatial coordinate is the so-called scaling factor of the Logunov metric of the effective Riemann space, acts as the Big Bang model. The primordial atom in superspace-time corresponds to spatialtime structures(spheres, lines, and surfaces of a level) of the Minkowski spacetime real within the Logunov gravitation theory, the foregoing structures being filled with a scalar field with a negative density of potential energy. © 2013 Springer Science+Business Media New York.
