Analog computers are systems that perform computations by manipulating physical quantities such as electrical current, that map math variables, instead of representing information using abstraction ...

Order doesn’t always form perfectly—and those imperfections can be surprisingly powerful. In materials like liquid crystals, ...

Abstract: Recently, analog matrix inversion circuits (INV) have demonstrated significant advantages in solving matrix equations. However, solving large-scale sparse tridiagonal linear systems (TLS) ...

Algorithms are precise step-by-step techniques for solving problems, guaranteeing a correct answer. Heuristics are quick "rule of thumb" methods that help solve everyday problems faster.

Abstract: Due to the availability of maintaining the orthogonality between transmit signals and effectively leveraging time resources, the Doppler division multiplexing (DDM) method has been widely ...
