One of the first magazines to convert from a print magazine format to an online only magazine was the computer magazine Datamation. Some online magazines distributed through the World ... |
https://en.wikipedia.org/wiki/Rough%20set | In computer science, a rough set, first described by Polish computer scientist Zdzisław I. Pawlak, is a formal approximation of a crisp set (i.e., conventional set) in terms of a pair of sets which give the lower and the upper approximation of the original set. In the standard version of rough set theory (Pawlak 1991),... |
https://en.wikipedia.org/wiki/Grothendieck%20group | In mathematics, the Grothendieck group, or group of differences, of a commutative monoid is a certain abelian group. This abelian group is constructed from in the most universal way, in the sense that any abelian group containing a homomorphic image of will also contain a homomorphic image of the Grothendieck group ... |

https://en.wikipedia.org/wiki/Multilocus%20sequence%20typing | Multilocus sequence typing (MLST) is a technique in molecular biology for the typing of multiple loci, using DNA sequences of internal fragments of multiple housekeeping genes to characterize isolates of microbial species.
The first MLST scheme to be developed was for Neisseria meningitidis, the causative agent of men... |
https://en.wikipedia.org/wiki/Headroom%20%28audio%20signal%20processing%29 | In digital and analog audio, headroom refers to the amount by which the signal-handling capabilities of an audio system can exceed a designated nominal level. Headroom can be thought of as a safety zone allowing transient audio peaks to exceed the nominal level without damaging the system or the audio signal, e.g., via... |
https://en.wikipedia.org/wiki/Predistortion | Predistortion is a technique used to improve the linearity of radio transmitter amplifiers.
Radio transmitter amplifiers in most telecommunications systems are required to be "linear", in that they must accurately reproduce the signal present at their input. An amplifier that compresses its input or has a non-linear i... |
