Analytically approximation solution to $$R^{2}$$ gravity

open access: yesThe European Physical Journal C, 2023
AbstractIn this paper, we obtain analytical approximate black hole solutions in the framework of f(R) gravity and the absence of a cosmological constant. In this area, we apply the equations of motion of the theory to a spherically symmetric spacetime with one unknown function and derive black hole solutions without any constraints on the Ricci scalar.

Analytical solution approximation for bearing [PDF]

open access: yesAIP Conference Proceedings, 2017
The purpose of lubrication is to separate two surfaces sliding past each other with a film of some material which can be sheared without causing any damage to the surfaces. Reynolds equation is a basic equation for fluid lubrication which is applied in the bearing problem. This equation can be derived from Navier-Stokes equation and continuity equation.
