Weyl-Euler-Lagrange Equations of Motion on Flat Manifold [PDF]

open access: yesAdvances in Mathematical Physics, 2015
This paper deals with Weyl-Euler-Lagrange equations of motion on flat manifold. It is well known that a Riemannian manifold is said to be flat if its curvature is everywhere zero. Furthermore, a flat manifold is one Euclidean space in terms of distances.

Euler-Lagrange optimization of electric drives with DTM method

open access: yesMATEC Web of Conferences, 2018
Euler-Lagrange optimization method is exploited here to develop energy saving position control strategy valid for a.c. drives. The optimization principle respects copper losses minimization only.

An electrical interpretation of mechanical systems via the pseudo-inductor in the Brayton-Moser equations [PDF]

open access: yes, 2005
In this paper an analogy between mechanical and electrical systems is presented, where, in contrast to the traditional analogy, position dependence of the mass inertia matrix is allowed. In order to interpret the mechanical system in an electrical manner,

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

open access: yes, 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]

open access: yes, 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.

Estimating Euler equations [PDF]

open access: yes, 2002
In this paper we consider conditions under which the estimation of a log-linearized Euler equation for consumption yields consistent estimates of preference parameters.

Numerical Solution of Differential Equations of Elastic Curves in 3-dimensional Anti-de Sitter Space [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2023
In this paper, we aim to extend the Darboux frame field into 3-dimensional Anti-de Sitter space and obtain two cases for this extension by considering a parameterized curve on a hypersurface; then we carry out the Euler-Lagrange equations and derive ...

Higher Order Hamiltonian Systems with Generalized Legendre Transformation

open access: yesMathematics, 2018
The aim of this paper is to report some recent results regarding second order Lagrangians corresponding to 2nd and 3rd order Euler–Lagrange forms. The associated 3rd order Hamiltonian systems are found.

A direct method for solving fractional order variational problems by hat basis functions

open access: yesAin Shams Engineering Journal, 2018
This paper presents a numerical technique for solving a class of fractional variational problems using a direct method based on operational matrix of generalized hat basis function. The fractional derivative is defined in the Caputo sense.Minimization of
