Controlled Lagrangian and Hamiltonian Systems [PDF]
any control systems are mechanical systems. The unique feature of mechanical systems is the notion of energy, which gives much information on the stability of equilibria.

Numerical models are associated with uncertainties that can be reduced through data assimilation (DA). Lower costs have driven a recent tendency to use Lagrangian instruments such as drifters and floats to obtain information about water bodies.

A Fourier approach to Lagrangian vortex detection [PDF]
We study the transport properties of coherent vortices over a finite-time duration. Here, we reveal that such vortices can be identified based on the frequency-domain representation of Lagrangian trajectories. We use Fourier analysis to convert particles’ trajectories from their time domain to a presentation in the frequency domain.

BRST-BV approach to continuous-spin field
Using BRST-BV approach, massless and massive continuous-spin fields propagating in the flat space are studied. For such fields, BRST-BV gauge invariant Lagrangian is obtained.

A Backwards-Tracking Lagrangian-Eulerian Method for Viscoelastic Two-Fluid Flows
A new Lagrangian–Eulerian method for the simulation of viscoelastic free surface flow is proposed. The approach is developed from a method in which the constitutive equation for viscoelastic stress is solved at Lagrangian nodes, which are convected by ...

Lagrangian relaxation heuristics for the uncapacitated single-source multi-product facility location problem [PDF]
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 Lagrangian Approach to Transport of Momentum and Biomass in Aquatic Biological Systems [PDF]
In recent years, a Lagrangian Coherent Structures (LCS) method was developed to identify boundaries between distinct kinematic regions in unsteady flows.

Lagrangian approach in spin-oscillations problem
Lagrangian of electronic liquid in magneto-inhomogeneous micro-conductor has been constructed. A corresponding Euler-Lagrange equation has been solved. It was shown that the described system has eigenmodes of spin polarization and total electric current ...
