Mean field limit of interacting filaments and vector valued non linear PDEs

, 2016
Families of $N$ interacting curves are considered, with long range, mean field type, interaction. A family of curves defines a 1-current, concentrated on the curves, analog of the empirical measure of interacting point particles.

A Meshfree Solver for the MEG Forward Problem [PDF]

, 2015
Noninvasive estimation of brain activity via magnetoencephalography (MEG) involves an inverse problem whose solution requires an accurate and fast forward solver. To this end, we propose the Method of Fundamental Solutions (MFS) as a meshfree alternative

Vortex density fluctuations in quantum turbulence

, 2011
We compute the frequency spectrum of turbulent superfluid vortex density fluctuations and obtain the same Kolmogorov scaling which has been observed in a recent experiment in Helium-4.

Tree method for quantum vortex dynamics

, 2011
We present a numerical method to compute the evolution of vortex filaments in superfluid helium. The method is based on a tree algorithm which considerably speeds up the calculation of Biot-Savart integrals.

Conservation of geometric structures for non-homogeneous inviscid incompressible fluids [PDF]

, 2012
We obtain a result about propagation of geometric properties for solutions of the non-homogeneous incompressible Euler system in any dimension $N\geq2$.

Artificial neural network-based method for overhead lines magnetic flux density estimation

Journal of Electrical Engineering
This paper presents an artificial neural network (ANN) based method for overhead lines magnetic flux density estimation. The considered method enables magnetic flux density estimation for arbitrary configurations and load conditions for single-circuit ...

Análise da Lei de Biot-Savart em comparação com a força entre elementos de corrente de Ampère

, 2017
Nowadays, we use Biot-Savart’s Law and Grassmann’s force to study the magnetic fields effects. We can observe that this force apparently do not always satisfy the principle of action and reaction.

Regularized Biot–Savart Laws for Modeling Magnetic Flux Ropes [PDF]

, 2017
Many existing models assume that magnetic flux ropes play a key role in solar flares and coronal mass ejections (CMEs). It is therefore important to develop efficient methods for constructing flux-rope configurations constrained by observed magnetic data

Stochastic vortex method for forced three-dimensional Navier--Stokes equations and pathwise convergence rate

, 2010
We develop a McKean-Vlasov interpretation of Navier-Stokes equations with external force field in the whole space, by associating with local mild $L^p$-solutions of the 3d-vortex equation a generalized nonlinear diffusion with random space-time birth ...

The Shapes of Flux Domains in the Intermediate State of Type-I Superconductors

, 1997
In the intermediate state of a thin type-I superconductor magnetic flux penetrates in a disordered set of highly branched and fingered macroscopic domains.
