Abstract: Staircase approximation in the simulation of the arbitrarily irregular surface will cause artificial interference of wavefield. The body-fit coordinate transformation can accurately simulate ...

ABSTRACT: This paper presents a comprehensive numerical study of the two-dimensional time-dependent heat conduction equation using the Forward Time Centered Space (FTCS) finite difference scheme. The ...

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 ...

Abstract: The moving window finite-difference time domain (MW-FDTD) method reduces the computational domain by following the propagation of the main pulse front and is widely used for solving ...

In numerous physical and biological systems, differential equations with parameters are commonly used to model specific behaviors or phenomena. These parameters frequently represent physical ...

Introduction: Fractional diffusion equations offer an effective means of describing transport phenomena exhibiting abnormal diffusion pat-terns, often eluding traditional diffusion models. Methods: We ...

Which A.I. system writes the best computer code or generates the most realistic image? Right now, there’s no easy way to answer those questions. Credit...Davide Comai Supported by By Kevin Roose ...

New York City's new rat-killing method has wiped out rats on a strip in the Upper East Side. The carbon-monoxide method kills the rats but doesn't address the underlying issues. Rat and pest experts ...
