Part 2: Time Derivatives of Unit Vectors in Spherical Coordinates

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Vector Potentials for Anisotropic Uniaxial Media with Sources in Spherical Coordinates

Abstract: A vector potential formulation is developed for an anisotropic uniaxial media in spherical coordinates and also includes source terms. It is shown that a Debye-like gauge reduces the ...

Angles-Only Relative Navigation in Spherical Coordinates Using Unscented Kalman Filter

Abstract: A novel Angles-only relative navigation method based on Unscented Kalman Filter (UKF) in spherical coordinates is proposed, for long-distance autonomous orbit rendezvous with unknown ...

sympy.vector.express doesn't express field in spherical coordinates

I am using the vector module to define a field in Cartesian coordinates and I want to get an expression for that field in spherical coordinates: from sympy.vector import CoordSys3D, express ...

This Matlab code allows you to visualize the spherical histograms of the vector distribution in space.

Bin selection is very important in such a visualisation. The most traditional lattitude and longitude division of a unit sphere, generate bins with equal spacing of angle in both azimithul and polar ...
