Analytical Approach to the Calculation of Three-Dimensional Transducers for the Acoustic Control Methods

For diagnostic acoustic methods piezoelectric ceramic circular disks are typically used as active transducer elements. To calculate the response of such transducers, simplified numerical calculation methods, having limited applicability, are widely used. In the present work the strict analytical methods of elasticity theory have been used to calculate the three-dimensional vibrations of circular piezoelectric disks having a general dependence on both diameter and thickness. The approach we employed is based on the eigenfunction method of dynamic electric elasticity developed in [1]

Unconventional magnetism of non-uniform distribution of Co in TiO2 nanoparticles

High-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD) analysis, electron paramagnetic resonance (EPR), X-ray absorption spectroscopy (XAS), magnetic methods, and density-functional theory (DFT) calculations were applied for the investigations of Co-doped anatase TiO2 nanoparticles (∼20 nm). It was found that high-spin Co2+ ions prefer to occupy the interstitial positions in the TiO2 lattice which are the most energetically favourable in compare to the substitutional those. A quantum mechanical model which operates mainly on two types of Co2+ – Co2+ dimers with different negative exchange interactions and the non-interacting paramagnetic Co2+ ions provides a satisfactorily description of magnetic properties for the TiO2:Co system. © 2020 Elsevier B.V.Russian Foundation for Basic Research.

Capability assessment for application of clay mixture as barrier material for irradiated zirconium alloy structure elements long-term processing for storage during decommissioning of uranium-graphite nuclear reactors

The radionuclide composition and the activity level of the irradiated zirconium alloy E110, the radionuclide immobilization strength and the retention properties of the mixed clay barrier material with respect to the radionuclides identified in the alloy were investigated to perform the safety assessment of handling structural units of zirconium alloy used for the technological channels in uranium-graphite reactors. The irradiated zirconium alloy waste contained the following activation products:{93m}Nb and the long-lived {94}Nb, {93}Zr radionuclides. Radionuclides of {60}Co, {137}Cs, {90}Sr, and actinides were also present in the alloy. In the course of the runs no leaching of niobium and zirconium isotopes from the E110 alloy was detected. Leach rates were observed merely for {60}Co and {137}Cs present in the deposits formed on the internal surface of technological channels. The radionuclides present were effectively adsorbed by the barrier material. To ensure the localization of radionuclides in case of the radionuclide migration from the irradiated zirconium alloy into the barrier material, the sorption properties were determined of the barrier material used for creating the long-term storage point for the graphite stack from uranium-graphite reactors

Multi-Agent Analysis of Scenarios for "arctic Smart City"

An approach to formalizing problems of municipal management in the Russian Arctic via smart city technologies is considered on the example of city Salekhard. An analysis of modern smart city concepts and prospects for integrating such technologies as BIM, GIS, and CIM is given. A discussion is based on comparison of two options to implement smart city technologies. Those are: 1) the inertial scenario of development adopted in the Strategy of the municipality Salekhard city, and 2) an alternative scenario corresponding to the innovation model of multicomponent sustainable system which includes energy subsystems. A multi-agent formalization of city management presents specific object features, including factors of the Northern nature. The framework of a four-component model of the flow distribution of resources: material, energy, information, financial, is applied. © Published under licence by IOP Publishing Ltd.The reported research was partly funded by Russian Foundation for Basic Research and the government of the Yamal region of the Russian Federation, grant № 19-48-890001

Basis for the model of parameter permeability prediction of productive strata in oil and gas deposits development

Basis for prediction of strata permeability of oil and gas deposits has been presented. The prediction model from the viewpoint of continuum mechanics (the theory of viscosity-elastic body creeping) is justified in terms of estimating deformation gradient, water permeability, piezoconductivity and permeability of hydrocarbon productive strata. To construct the pattern of these parameters the programming complex «Balance-Hydrodynamics» was used. One of the units of this complex allows the construction of predictive permeability patterns to use only the results of well prospecting seismology and hydrodynamic tests. The method was successfully applied at a number of hydrocarbon deposits development in Tomsk region
