  2. Lexical chain - Wikipedia

    en.wikipedia.org/wiki/Lexical_chain

    The sequence between semantic related ordered words is classified as a lexical chain. [1] A lexical chain is a sequence of related words in writing, spanning narrow (adjacent words or sentences) or wide context window (entire text). A lexical chain is independent of the grammatical structure of the text and in effect it is a list of words that ...

  3. Ordinal numeral - Wikipedia

    en.wikipedia.org/wiki/Ordinal_numeral

    The first two in the sequence are by far the most common; 'tertiary' appears occasionally, and higher numbers are rare except in specialized contexts ('quaternary period'). The Greek series proto- , deutero- , trito- , ... is only found in prefixes, generally scholarly and technical coinages, e.g. protagonist, deuteragonist, tritagonist ...

  4. Downsampling (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Downsampling_(signal...

    [1] [2] When the process is performed on a sequence of samples of a signal or a continuous function, it produces an approximation of the sequence that would have been obtained by sampling the signal at a lower rate (or density, as in the case of a photograph). Decimation is a term that historically means the removal of every tenth one.

  5. Arborescence (graph theory) - Wikipedia

    en.wikipedia.org/wiki/Arborescence_(graph_theory)

    The term arborescence comes from French. [6] Some authors object to it on grounds that it is cumbersome to spell. [7] There is a large number of synonyms for arborescence in graph theory, including directed rooted tree, [3] [7] out-arborescence, [8] out-tree, [9] and even branching being used to denote the same concept. [9]

  6. Unpaired word - Wikipedia

    en.wikipedia.org/wiki/Unpaired_word

    An unpaired word is one that, according to the usual rules of the language, would appear to have a related word but does not. [1] Such words usually have a prefix or suffix that would imply that there is an antonym, with the prefix or suffix being absent or opposite.

  7. List of integer sequences - Wikipedia

    en.wikipedia.org/wiki/List_of_integer_sequences

    "subtract if possible, otherwise add": a(0) = 0; for n > 0, a(n) = a(n − 1) − n if that number is positive and not already in the sequence, otherwise a(n) = a(n − 1) + n, whether or not that number is already in the sequence.

  8. Subsequence - Wikipedia

    en.wikipedia.org/wiki/Subsequence

    The relation of one sequence being the subsequence of another is a partial order. Subsequences can contain consecutive elements which were not consecutive in the original sequence. A subsequence which consists of a consecutive run of elements from the original sequence, such as B , C , D , {\displaystyle \langle B,C,D\rangle ,} from A , B , C ...

  9. Subadditivity - Wikipedia

    en.wikipedia.org/wiki/Subadditivity

    A sequence {} is called subadditive if it satisfies the inequality + + for all m and n. This is a special case of subadditive function, if a sequence is interpreted as a function on the set of natural numbers.
