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 ...

A sufficient condition for a finite-time $L_2 $ singularity of the 3d Euler Equations [PDF]

, 2005
A sufficient condition is derived for a finite-time $L_2 $ singularity of the 3d incompressible Euler equations, making appropriate assumptions on eigenvalues of the Hessian of pressure.

Strong continuity for the 2D Euler equations [PDF]

, 2015
We prove two results of strong continuity with respect to the initial datum for bounded solutions to the Euler equations in vorticity form. The first result provides sequential continuity and holds for a general bounded solution.

Pitfalls in Investment Euler Equations [PDF]

SSRN Electronic Journal, 2001
This paper investigates three pitfalls concerning the test of the Euler equation facing quadratic adjustment costs and perfect capital markets on a large balanced panel data of 4025 French firms. First, the quadratic parameterization of adjustment costs is too restrictive, and power series approximations of adjustment costs are tested.

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.

A New Technique for Solving Neutral Delay Differential Equations Based on Euler Wavelets

Complexity, 2022
An effective numerical scheme based on Euler wavelets is proposed for numerically solving a class of neutral delay differential equations. The technique explores the numerical solution via Euler wavelet truncated series generated by a set of functions ...

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.
