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.

Calculating the High‐Latitude Ionospheric Electrodynamics Using a Machine Learning‐Based Field‐Aligned Current Model

Space Weather, Volume 22, Issue 4, April 2024.
Abstract We introduce a new framework called Machine Learning (ML) based Auroral Ionospheric electrodynamics Model (ML‐AIM). ML‐AIM solves a current continuity equation by utilizing the ML model of Field Aligned Currents of Kunduri et al. (2020, https://doi.org/10.1029/2020JA027908), the FAC‐derived auroral conductance model of Robinson et al.

Intracycle RPM control for vertical axis wind turbines

Wind Energy, Volume 27, Issue 3, Page 202-224, March 2024.
Abstract The wind energy market is currently dominated by horizontal axis wind turbines (HAWTs); however, vertical axis wind turbines (VAWTs) are emerging as a design alternative, especially for deep‐water offshore siting due to their low center of gravity, ease of access to drivetrain components, and overall simplicity.

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.

Modified Bean Model and FEM Method Combined for Persistent Current Calculation in Superconducting Coils [PDF]

, 2000
Field variations in the LHC superconducting magnets, e. g. during the ramping of the magnets, induce magnetization currents in the superconducting material, the so-called persistent currents that do not decay but persist due to the lack of resistivity ...

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 ...
