Analytical Solution to 1D Compressible Navier-Stokes Equations

open access: yesJournal of Function Spaces, 2021
There exist complex behavior of the solution to the 1D compressible Navier-Stokes equations in half space. We find an interesting phenomenon on the solution to 1D compressible isentropic Navier-Stokes equations with constant viscosity coefficient on x,t ...

Semi-analytical Solution of Dirac equation in Schwarzschild Geometry [PDF]

open access: yes, 1999
Separation of the Dirac equation in the spacetime around a Kerr black hole into radial and angular coordinates was done by Chandrasekhar in 1976. In the present paper, we solve the radial equations in a Schwarzschild geometry semi-analytically using ...

Convergency and Stability of Explicit and Implicit Schemes in the Simulation of the Heat Equation

open access: yesApplied Sciences, 2021
Some strategies for solving differential equations based on the finite difference method are presented: forward time centered space (FTSC), backward time centered space (BTSC), and the Crank-Nicolson scheme (CN).

An Analysis Method of Symplectic Dual System for Decagonal Quasicrystal Plane Elasticity and Application

open access: yesCrystals, 2022
The symplectic solution system of decagonal quasicrystal elastic mechanics is considered. Hamiltonian dual equations together with the boundary conditions are investigated by utilizing the principle of minimum potential energy.

Constant threshold correction to electrically charged dilatonic black holes [PDF]

open access: yes, 1996
We investigate the effect of a constant threshold correction to a general non-extreme, static, spherically symmetric, electrically charged black hole solution of the dilatonic Einstein-Maxwell Lagrangian, with an arbitrary coupling $\beta$ between the ...

Analytical solution of a generalized Penna model

open access: yes, 2004
In 1995 T.J.Penna introduced a simple model of biological aging. A modified Penna model has been demonstrated to exhibit behaviour of real-life systems including catastrophic senescence in salmon and a mortality plateau at advanced ages.

Analytical solution for the lattice Boltzmann model beyond Naviers-Stokes [PDF]

open access: yes, 2010
To understand lattice Boltzmann model capability for capturing nonequilibrium effects, the model with first-order expansion of the equilibrium distribution function is analytically investigated.
