The researchers turned to hydrogels, which are water-rich, jelly-like polymers that respond to temperature and chemicals. But instead of layering different materials or embedding electronics, they ...
A comprehensive JavaScript library for retrieving airport information by IATA codes, ICAO codes, and various other criteria. This library provides easy access to a large dataset of airports worldwide ...
Order doesn’t always form perfectly—and those imperfections can be surprisingly powerful. In materials like liquid crystals, tiny “defects” emerge when symmetry breaks, shaping everything from cosmic ...
Abstract: Code-hopping multiple access (CHMA) technology is an effective approach for improving the user capacity of direct sequence spread spectrum systems. However, the use of randomly generated ...
Abstract: In this letter, we propose a two-stage method to design finite-length puncturing patterns for LDPC codes with Hadamard constraints. At the first stage, we propose the distribution of ...
