Numerical solutions of the randall-wilkins and one trap one recombination models for first order kinetic

Cumhuriyet Science Journal, 2021
Randall-Wilkins and One Trap One Recombination (otor) models have been proposed to explain thermoluminescence emission and it should be emphasized that each model has its own allowed charge carrier transitions, trapping parameters and differential ...

B-Spline Solutions of General Euler-Lagrange Equations

Mathematics, 2019
The Euler-Lagrange equations are useful for solving optimization problems in mechanics. In this paper, we study the B-spline solutions of the Euler-Lagrange equations associated with the general functionals.

SOLUSI DARI PERSAMAAN CAUCHY–EULER NONHOMOGEN KASUS LOGARITMIK

E-Jurnal Matematika, 2020
Ordinary differential equation is one form of differential equations that are often found in everyday life. One form of ordinary differential equations which has non–constant coefficients is the Cauchy–Euler differential equation.

Fractal Logistic Equation

Fractal and Fractional, 2019
In this paper, we give difference equations on fractal sets and their corresponding fractal differential equations. An analogue of the classical Euler method in fractal calculus is defined. This fractal Euler method presets a numerical method for solving

The Lie group Euler methods of multibody system dynamics with holonomic constraints

Advances in Mechanical Engineering, 2018
The Euler methods on Lie group are developed for the differential–algebraic equations of multibody system dynamics with holonomic constraints. The implicit Euler method is used to solve the differential–algebraic equations as Euler–Lagrange equations on ...

Differential-integral Euler–Lagrange equations [PDF]

Iranian Journal of Numerical Analysis and Optimization
We study the calculus of variations problem in the presence of a system of differential-integral (D-I) equations. In order to identify the necessary optimality conditions for this problem, we derive the so-called D-I Euler–Lagrange equations.

On a Quasi-Neutral Approximation to the Incompressible Euler Equations

Journal of Applied Mathematics, 2012
We rigorously justify a singular Euler-Poisson approximation of the incompressible Euler equations in the quasi-neutral regime for plasma physics. Using the modulated energy estimates, the rate convergence of Euler-Poisson systems to the incompressible ...

Ulam stability for second-order linear differential equations with three variable coefficients

Results in Applied Mathematics, 2022
This study deals with Ulam stability of second-order linear differential equations of the form e(x)y′′+f(x)y′+g(x)y=0. The method established by Cădariu et al. (2020) is extended.
