A stochastic model of electron-donor-acceptor complex (EDAC) interacting coherently with a short laser pulse within the charge transfer band is considered in the low-field approximation. An analytical expression for the probability of detection the complex in the excited electronic state is obtained within the perturbation theory in the optical coupling parameter. New computational scheme for numerical simulations of coherent optical excitation in EDACs is proposed. This scheme extends the recrossing-algorithm of the Brownian simulation (RABS) method developed earlier for simulations of nonequilibrium electron transfer within the multimode Zusman/Jortner-Bixon model. The proposed algorithm implies calculations of stochastic trajectories of quasiparticles in multidimensional space of solvent coordinates, as well as transitions between different electronic and vibrational states of EDAC. Applicability conditions and efficiency of the algorithm are discussed.A stochastic model of electron-donor-acceptor complex (EDAC) interacting coherently with a short laser pulse within the charge transfer band is considered in the low-field approximation.

Volyn province serves as a case study area in the research. Calculations and maps show that for a time period of 10 years soil deflation and sand blowing are probable for almost all the province’s area, although before the land reclamation works these processes have been observed within arable lands only.The mathematical reliability theory and landscape mapping were used for quantitative assessment and mapping of the probabilities of hazardous processes caused by the wind for the landscapes of fluvioglacial sandy lowlands of the Eastern Europe.

This study investigates the structural compression properties of the additive manufactured (AM) Ti-6Al-4V lattice structure using LS-Dyna simulation analysis software and calculates its mechanical properties under different porosities and different pattern designs. Ti-6Al-4V alloys formed by using additive manufacturing produced elliptic holes with long and short axes due to the difference in the direction of construction. These holes could be eliminated and the materials could be compacted by hot isostatic pressing (HIP) treatment. Compactness of the frame element achieved 99.9% and drastically reduced the anisotropic behavior caused by the fabrication process. For the experimental testing, the samples with different porosities and the A-type and AZ-type designs were employed in compression experiment. In the meantime, the Young’s modulus, the yield strength, plateau stress and other mechanical behavior were investigated by CAE simulation. The plateau stress, which is an important property for some biomedical applications, was calculated with satisfactory accuracy compared with experimental measurements. The simulated results of the designed lattice structures with different porosity contents were able to adopt the Gibson-Ashby model to determine their failure mechanisms. Finally, the CAE simulation for the design of an auxetic material was demonstrated.This study investigates the structural compression properties of the additive manufactured (AM) Ti-6Al-4V lattice structure using LS-Dyna simulation analysis software and calculates its mechanical properties under different porosities and different pattern designs.

The eggs volume (Vegg, m3), eggs surface (Segg, m2), incubation times (Tinc, s) and oxygen permeability coefficient (KO2, m/s) trough inner egg membrane are connected by allometric relationship: Vegg /(Segg·Tinc)=KO2 (for 1 Torr oxygen pressure trough egg shell membranes).

Water absorption coefficient, apparent moisture diffusivity, thermal conductivity, and specific heat capacity of all materials, as fundamental hygric and thermal parameters, are measured in a dependence on moisture content. The measured data will be used as input parameters in computer simulation studies which will provide moisture and temperature fields necessary for an appropriate design of interior thermal insulation systems.The properties of three thermal insulation wood fiber boards suitable for the application on the interior side of historical building envelopes are studied in the paper.

The hyperangular momenta and their eigenfunctions, the hyperspherical harmonics, are the mathematical apparatus characterizing the hyperspherical representation of molecular dynamics. To circumvent the restriction to the application of the hyperspherical methods, due to exceedingly high computational costs, a classical mechanics hyperspherical formulation has been developed suitable for applications to clusters and large molecular system dynamics.
