ObjectivesThe hydrodynamic performance of three-dimensional hydrofoils with different shapes is studied in order to find the optimal hydrofoil geometry.Methods NACA 0012 hydrofoil model with different aspect ratios, tip ratios, forward-swept and back-swept shapes are used to simulated the flow field of the hydrofoil with multi-DOF coupling motion M
Effective Sectoral Policy and Civil Service (on the Example of the Health Sector)
The purpose of the article is to assess the effectiveness of the implementation of public sectoral policy on the example of public healthcare in comparison with the development of the civil service Eyeliner system in this sector.We use the methodology of factor analysis, i.e.economic-statistical methods, regression-correlation analysis, principle c
Cavity assisted measurements of heat and work in optical lattices
We propose a method to experimentally measure the internal energy of a system of ultracold atoms trapped in optical lattices by coupling 5 Inch them to the fields of two optical cavities.We show that the tunnelling and self-interaction terms of the one-dimensional Bose-Hubbard Hamiltonian can be mapped to the field and photon number of each cavity,
