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 letter proposes a generalized and controllable-stability conformal method to address stability challenges inherent in conformal finite-difference time-domain algorithms. A quantitative ...

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 ...

DALLAS — As severe weather comes to North Texas, you might get a Tornado Watch or a Tornado Warning for your county. We understand it can be confusing to know the difference and determine how ...

Several red onions, most cut lengthwise, with three crosswise-cut onion rings - NIKCOA/Shutterstock Sometimes recipes dictate whether something should be cut lengthwise or crosswise. And while it's ...

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 ...

AI companies face delays and challenges with training new large language models Some researchers are focusing on more time for inference in new models Shift could impact AI arms race for resources ...

The research findings have demonstrated that finite difference methods offer a powerful tool for approximating option prices and hedging parameters, especially in cases where closed-form solutions are ...
