numerical character
1Numerical differentiation — is a technique of numerical analysis to produce an estimate of the derivative of a mathematical function or function subroutine using values from the function and perhaps other knowledge about the function. Contents 1 Finite difference formulae 1 …
2Numerical diffusion — is a difficulty with computer simulations of continua (such as fluids) wherein the simulated medium exhibits a higher diffusivity than the true medium. This phenomenon can be particularly egregious when the system should not be diffusive at all,… …
3Numerical taxonomy — is a classification system in biological systematics which deals with the grouping by numerical methods of taxonomic units based on their character states.[1]. It aims to create a taxonomy using numeric algorithms like cluster analysis rather… …
4Character (computing) — In computer and machine based telecommunications terminology, a character is a unit of information that roughly corresponds to a grapheme, grapheme like unit, or symbol, such as in an alphabet or syllabary in the written form of a natural… …
5Character creation — This article is about customizable game characters. For the process of designing fictional characters, see characterisation …
6Character mask — Part of a series on Marxism …
7Numerical cipher — In classical cryptography, the numerical chiper which combines the Polybius square with transposition, and uses fractionation to achieve diffusion. It was invented around 1904 by Albus Volger. Operation First, a mixed alphabet Polybius square is… …
8numerical taxonomy — The grouping by numerical methods of taxonomic units into taxa based on their character states …
9numerical taxonomy — an arithmetic method of classifying large numbers of bacterial strains on the basis of their overall similarity to one another, according to the number of phenotypic characters they share, each character being given equal weight. Called also… …
10character index — A numerical value, compounded from the ratings of several characters, indicating a degree of difference of related taxa; also a rating of an individual, particularly a hybrid, in comparison with its most nearly related species …
