Lagrangian relaxation heuristics for the uncapacitated single-source multi-product facility location problem [PDF]
, 2013 Facility location problem is one of the strategic logistical drivers within the supply chain which is a hard to solve optimization problem. In this study, we focus on the uncapacitated single-source multi-product production/distribution facility location

A novel soot concentration field estimator applied to sooting ethylene/air laminar flames
Engineering Applications of Computational Fluid Mechanics, 2019 Soot formation modeling, when incorporated into computational fluid dynamics of industrial devices, can be numerically prohibitive. Nonetheless, there remains a significant push to predict soot formation, so as to aid in environmentally sustainable ...

Variational problem, Lagrangian and $\mu$-conservation law of the generalized Rosenau-type equation [PDF]
AUT Journal of Mathematics and ComputingThe goal of this article is to compute conservation law, Lagrangian and $\mu$-conservation law of the generalized Rosenau-type equation using the homotopy operator, the $\mu$-symmetry method and the variational problem method.

THE QUATERNIONIC DIRAC LAGRANGIAN [PDF]
Modern Physics Letters A, 1996 We discuss the use of the variational principle within quaternionic quantum mechanics. This is nontrivial because of the noncommutative nature of quaternions. We derive the Dirac-Lagrangian density corresponding to the two-component Dirac equation. This Lagrangian is complex projected as anticipated in previous articles and this feature is necessary ...

The oscillator's model with broken symmetry
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015 The equations of the oscillator motion are considered. The exact solutions are given in the form of exponents with an additional parameter that characterizes the asymmetry of the oscillations.

Cyclic Lagrangian Submanifolds and Lagrangian Fibrations
Tokyo Journal of Mathematics, 2005 Recall that a symplectic manifold \((M,\omega)\) is called prequantizable if there exists a nonnegative number \(\gamma_\omega\) such that the period group \(\Gamma_\omega= \{[\omega](A)= \int_A \omega: A\in H_2(M,\mathbb{Z})\}\subset \mathbb{R}\) is of the form \(\Gamma_\omega= \gamma_\omega\cdot\mathbb{Z}\).

Journal of Mathematical Physics, 2007 Searching for a Lagrangian may seem either a trivial endeavor or an impossible task. In this paper, we show that the Jacobi last multiplier associated with the Lie symmetries admitted by simple models of classical mechanics produces (too?) many Lagrangians in a simple way. We exemplify the method by such a classic as the simple harmonic oscillator, the

Eulerian-on-Lagrangian Cloth [PDF]
, 2015 We present a new, Eulerian-on-Lagrangian approach for modeling cloth. When a cloth modeled using the traditional Lagrangian approach is moved around an object with sharp corners, such as the edge of a table, the cloth cannot always bend smoothly around ...
