Differential-integral Euler–Lagrange equations [PDF]
Iranian Journal of Numerical Analysis and OptimizationWe 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.

Revisiting lagrange relaxation (LR) for processing large-scale mixed integer programming (MIP) problems [PDF]
, 2004 Lagrangean Relaxation has been successfully applied to process many well known instances of NP-hard Mixed Integer Programming problems. In this paper we present a Lagrangean Relaxation based generic solver for processing Mixed Integer Programming ...

Error Estimation of Euler Method for the Instationary Stokes–Biot Coupled Problem
Journal of Mathematics, 2021 In this paper, we study a finite element computational model for solving the interaction between a fluid and a poroelastic structure that couples the Stokes equations with the Biot system. Equilibrium and kinematic conditions are imposed on the interface.

The Lagrange interpolation for He’s frequency formulation [PDF]
Journal of Low Frequency Noise, Vibration and Active Control, 2020 Nonlinear oscillators arise everywhere in engineering, and though there are many analytical methods available, a fast and accurate estimation of the frequency–amplitude relationship is much needed in practical applications. He’s frequency formulation meets this requirement, but the local points are chosen randomly.

Rotational Constraint between Beams in 3-D Space [PDF]
Mechanical Sciences, 2018 In this paper, we develop two alternative formulations for the rotational constraint between the tangents to connected beams with large deformations in 3-D space. Such a formulation is useful for modeling bonded/welded connections between beams.
