Search Results for "wave equation"

... operators can also be used as layers in (convolutional) neural networks to implement physics-augmented deep learning algorithms thanks to its implementation of ChainRules's rrule for the linear operators representing the discre wave equation.

A computer code for simulation of electron-hydrogen scattering. Contains three (more or less) finished sub-programs: (a) “hex-ecs” which solves the Schrödinger equation in the B-spline basis, (b) “hex-dwba” which computes scattering variables for high energies using the distorted wave Born approximation of the first order and finally (c) “hex-db” which is a user interface to a plain SQLite database, where the intermediate results are being stored, and which is used to extract derived...

"chinese remainder" solves a system of equations over modulus quickly. crtwo is an improvement to Mathematica's release. crtwo: solves Chinese Remainder a pair at a time, (uses gcd), yet is still fast. Which means crtwo, unlike text book soln, uses an algorithm to solve or fail one mod equation at a time. showing win or fail of each eqn and solving other sawtooth intersections is possible, due to that. crAll2@crtwo provides n soln near x for CR using width of soln crchart3...

A program to solve dispersion equation in water waves mechanics using iterated and graphical methods.

This Matlab code with the finite element method based Partial Differential Equation Toolbox calculates and simulates the electromagnetic field, when a scatterer (copper) object is cloaked with transformation optics designed metamaterial. This electromagnetic cloaking effect can be studied and demonstrated with this program. The code includes two source type (finite length line source and point source), and two sets of metamaterial parameters (exact and reduced metamaterial parameters). You can...

Library to evaluate periodic Green's functions or Green's functions for wave guides for the Helmholtz equation using Ewald's method.

A Fast MAC based 3D Free surface fuid solver. Capable also of simulating viscoelastic fluids.Includes also wave equation solver for simulating shallow water phenomena.
