New schemes were developed to form the basis of the local approximation subspace, which were derived by approximating only the k 2 u term of the Helmholtz equation. The construction of a basis of the ...

py-pde is a Python package for solving partial differential equations (PDEs). The package provides classes for grids on which scalar and tensor fields can be defined. The associated differential ...

Computer (symbolic) algebra systems and libraries are used for manipulations with symbolic mathematical expressions. Usually, those libraries are capable of some calculus operations (differentiation, ...

(Courtesy: R.G. MacDonald, A. Yakovlev, and V. Pacheco-Peña, doi : 10.1117/1.APN.3.5.056007) Waveguide-based structures can solve partial differential equations by mimicking elements in standard ...

Back in the 1960s, Frank Drake, an American astrophysicist and astrobiologist, proposed an equation aimed at estimating the number of intelligent civilizations in our Universe. The equation ...

It posits that three times X plus twice Y totals 30. Thus our second equation is formulated as: 3x + 2y = 30. . Solving these equations isn't necessarily a walk in the park, but with a touch of ...

Fully differential amplifiers from Analog Devices offer precision DC specs and are designed to better reject high frequency PSRR and CMRR through their differential input and output architectures. The ...
