Slow, error-prone calculations by hand were unavoidable in the early 19th century, yet even small mistakes could ruin the designs for buildings and the journeys of ships; Charles Babbage’s ingenious ...

Abstract: This letter proposes an associated hermite finite-difference time-domain (AH FDTD) method suitable for nonuniform grids, which is implemented based on coordinate transformation. A coordinate ...

Photonic Finite-Difference Frequency-Domain (FDFD) Toolbox is a MATLAB Community Toolbox project, aiming to provide intuitive framework for photonic devices simulation using MATLAB. Customizable ...

This study presents a novel local meshless approach for solving one-dimensional Fisher’s equation, combining a local scheme, Gaussian radial basis functions (G-RBF), and a collocation technique. The ...

Systems of interacting electrons can show emergent, strong-correlation phenomena. The parquet equations self-consistently relate various propagation amplitudes of many-electron systems and thereby ...

The 1.0 version of the Hypertext Transfer Protocol, issued way back in 1996, only defined three HTTP verbs: GET, POST and HEAD. The most commonly used HTTP method is GET. The purpose of the GET method ...

The Taylor series expresses the value of a function at one point and its approximate value at another point using its derivatives. FDM uses this series to approximate the derivatives. Two dimensional ...

Calculating derivatives analytically is great until you realize the function to be differentiated looks like it was designed by an over caffeinated abstract artist. Enter the finite difference method: ...

This study investigates the thermal behaviour of unsteady hybrid nanofluid flow on an infinite vertical plate. The investigation takes into account parameters such as magnetohydrodynamics and ...

Abstract: This article presents the finite-difference time-domain (FDTD) method for gauge-invariant field-impulses, which constitute the fundamental physical quantities of electromagnetics (EM) in ...

Synthetic chemicals are everywhere—including in the food we eat, the water we drink, the products we use, the dust on our floors, and the air that we breathe. With all these acronyms, it’s not ...
