Numerical Simulation of Density Current Evolution in a Diverging Channel
Published 2012-01-01“…This study seeks to explore the ability of 2D width-averaged unsteady Reynolds-averaged Navier-Stokes (RANS) simulation approach for resolving density currents in an inclined diverging channel. 2D width-averaged unsteady RANS equations closed by a buoyancy-modified 𝑘−𝜀 turbulence model are integrated in time with a second-order fractional step approach coupled with a direct implicit method and discretized in space on a staggered mesh using a second-order accurate finite volume approach incorporating a high-resolution semi-Lagrangian technique for the convective terms. …”

Transfers as an effective instrument of public finance resilience
Published 2022-12-01“…It has been established that one of the instruments of resilience is interbudgetary transfers, the improvement of distribution methods of which makes it possible to increase the flexibility and adaptability of the regional economy in a period of environmental turbulence. The existing models for the use of intergovernmental transfers are identified and considered: 1) the introduction of blocks for the distribution of subsidies into the system of substantiation of budgetary appropriations based on the developed methods, 2) a binary model for managing the socio-economic development of the region, which performs the dual functioning of the transfer mechanism and priorities strategic development. …”

On the Safe-Haven Ability of Bitcoin, Gold, and Commodities for International Stock Markets: Evidence from Spillover Index Analysis
Published 2022-01-01“…In this paper, we aim to identify whether commonly recognized safe-haven assets, that is, bitcoin, gold, and commodities, can provide investors with effective hedging utility in international stock markets, especially during periods of extreme market turbulence. By using the spillover index method based on the TVP-VAR model, we find that firstly, bitcoin, gold, and commodities can only offer weak hedging effects on stock markets. …”
