A uniqueness theorem for the determination of sources in the Germain–Lagrange plate equation
(San Diego, 2013)
We prove a uniqueness result related to the Germain–Lagrange dynamic plate differential equation. We consider the equation {∂2u∂t2+△2u=g⊗f,in ]0,+∞)×R2,u(0)=0,∂u∂t(0)=0, where uu stands for the transverse displacement, ff ...

Implicit Lagrange-Routh equations and Dirac reduction
(Elsevier Science, 2016-06)
In this paper, we make a generalization of Routh´s reduction method for Lagrangian systems with symmetry to the case where not any regularity condition is imposed on the Lagrangian. First, we show how implicit Lagrange-Routh ...
An Euler-Lagrange Equation only Depending on Derivatives of Caputo for Fractional Variational Problems with Classical Derivatives
(International Academic Press, 2020-05-18)
In this paper we present advances in fractional variational problems with a Lagrangian depending on Caputo fractional and classical derivatives. New formulations of the fractional Euler-Lagrange equation are shown for the ...

Swarm control designs applied to a non-ideal load transportation system
(2010-07-14)
In this paper, a load transport system in platforms is considered. It is a transport device and is modelled as an inverted pendulum built on a car driven by a DC motor. The motion equations were obtained by Lagrange's ...

Convergence of the Lagrange-Galerkin method for the equations modelling the motion of a fluid-rigid system
(SIAM PUBLICATIONS, 2005)
In this paper, we consider a Lagrange-Galerkin scheme to approximate a two
dimensional °uid-rigid body problem. The equations of the system are the Navier-
Stokes equations in the °uid part, coupled with ordinary di®erential ...
