Modeling and interpolation of the ambient magnetic field by Gaussian processes

IEEE Transactions on Robotics, 2018
Anomalies in the ambient magnetic field can be used as features in indoor positioning and navigation. By using Maxwell's equations, we derive and present a Bayesian non-parametric probabilistic modeling approach for interpolation and extrapolation of the

International Geomagnetic Reference Field: the thirteenth generation

Earth, Planets and Space, 2021
In December 2019, the International Association of Geomagnetism and Aeronomy (IAGA) Division V Working Group (V-MOD) adopted the thirteenth generation of the International Geomagnetic Reference Field (IGRF). This IGRF updates the previous generation with

Modelling the Earth's magnetic field

American Journal of Physics, 2022
The Earth's magnetic field can be decomposed into spherical harmonics, and the exact coefficients of the decomposition can be determined through a few measurements of its value at different locations. Using measurements from a magnetometer on board the International Space Station, we computed the multipolar moments of an expansion in spherical ...

Theory of anisotropic exchange in laterally coupled quantum dots [PDF]

, 2010
The effects of spin-orbit coupling on the two-electron spectra in lateral coupled quantum dots are investigated analytically and numerically. It is demonstrated that in the absence of magnetic field the exchange interaction is practically unaffected by ...

The LHC Magnetic Field Model

Proceedings of the 2005 Particle Accelerator Conference, 2006
The compensation of the field changes during the beam injection and acceleration in the LHC requires an accurate forecast and an active control of the magnetic field in the accelerator. The LHC Magnetic Field Model is the core of this magnetic prediction system.

Bootstrapping the Coronal Magnetic Field with STEREO: I. Unipolar Potential Field Modeling [PDF]

, 2010
We investigate the recently quantified misalignment of $\alpha_{mis} \approx 20^\circ-40^\circ$ between the 3-D geometry of stereoscopically triangulated coronal loops observed with STEREO/EUVI (in four active regions) and theoretical (potential or ...
