A systematic approach to the SILH Lagrangian
Nuclear Physics B, 2015 We consider the electroweak chiral Lagrangian, including a light scalar boson, in the limit of small ξ=v2/f2. Here v is the electroweak scale and f is the corresponding scale of the new strong dynamics.

Lagrangian Approach to Dispersionless KdV Hierarchy [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2007 We derive a Lagrangian based approach to study the compatible Hamiltonian structure of the dispersionless KdV and supersymmetric KdV hierarchies and claim that our treatment of the problem serves as a very useful supplement of the so-called r-matrix ...

Ecological modeling and Lagrangian approach
Open Mathematics, 2013 Abstract A mathematical model is proposed for a quantitative estimation of the damage to biological resources resulting from a pollutant discharge into an aqueous environment. On the basis of the Lagrangian description of fluid motion a set of hydrophysical parameters is introduced with help of which hydrobiologists can estimate the ...

A Numerical Study of Friction Stir Welding for AA5754 Sheets to Evaluate Temperature Profile and Plastic Strain [PDF]
Engineering and Technology Journal, 2022 A full-dimensions 3-D numerical model based on the Lagrangian approach has been employed to predict the peak temperature and the plastic strain distribution in the FSW of (AA5754) joints using ABAQUS software.

Numerical investigation of the effect of different parameters on emitted shockwave from bubble collapse in a nozzle [PDF]
Journal of Particle Science and Technology, 2021 Cavitation can be extremely beneficial for the first spray breakup and to enhance atomization quality. An Eulerian/Lagrangian approach using Reynolds average Navier-Stokes (RANS) and bubble dynamic equations was used for the prediction of cavitation ...

Analytical and numerical solutions of radially symmetric aquifer thermal energy storage problems
Hydrology Research, 2023 Aquifer thermal energy storage (ATES) systems offer reduced energy costs, lower carbon emissions, and increased energy resilience. The feasibility, however, depends on several factors and usually require optimization.

Using a Lagrangian-Lagrangian approach for studying flow behavior inside a bubble column
Nuclear Engineering and Technology, 2023 Bubble columns are widely encountered in several industries, especially in the field of nuclear safety. The Eulerian-Eulerian and the Eulerian-Lagrangian methods are commonly used to investigate bubble columns.

Hamiltonian approach to lagrangian gauge symmetries [PDF]
Physics Letters B, 1999 We reconsider the problem of finding all local symmetries of a Lagrangian. Our approach is completely Hamiltonian without any reference to the associated action. We present a simple algorithm for obtaining the restrictions on the gauge parameters entering in the definition of the generator of gauge transformations.
