Abstract: We developed a finite-difference frequency-domain (FDFD) and a finite-difference time-domain (FDTD) drift-diffusion equations solver that takes the multilayered background into account for ...

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 ...

A new approach in the finite difference framework is developed, which consists of three steps: choosing the dimension of the local approximation subspace, constructing a vector basis for this subspace ...

“A kink is something sexual that someone likes to do with themselves or consensually with partners,” Torrisi explains. “This is usually something considered outside of mainstream sexual activities.” ...

Add a description, image, and links to the finite-differences-method topic page so that developers can more easily learn about it.

Solution of nonlinear two-point boundary-value problems is often an extremely difficult task. Quite apart from questions of reality and uniqueness, there is no established numerical technique for this ...

Abstract: The generalized finite difference method is applied to the advection problem. An optimization regarding choice of RBF function has been performed. Theoretical problems in 1D and 2D have been ...
