  2. Digital elevation model - Wikipedia

    en.wikipedia.org/wiki/Digital_elevation_model

    A digital terrain model (DTM) represents specifically the ground surface while DEM and DSM may represent tree top canopy or building roofs. While a DSM may be useful for landscape modeling , city modeling and visualization applications, a DTM is often required for flood or drainage modeling, land-use studies , [ 1 ] geological applications, and ...

  3. Document-term matrix - Wikipedia

    en.wikipedia.org/wiki/Document-term_matrix

    Certain function words such as and, the, at, a, etc., were placed in a "forbidden word list" table, and the frequency of these words was recorded in a separate listing... A special computer program, called the Descriptor Word Index Program, was written to provide this information and to prepare a document-term matrix in a form suitable for in ...

    en.wikipedia.org/wiki/Less-than_sign

    The less-than sign is a mathematical symbol that denotes an inequality between two values. The widely adopted form of two equal-length strokes connecting in an acute angle at the left, <, has been found in documents dated as far back as the 1560s.

  6. Nondeterministic Turing machine - Wikipedia

    en.wikipedia.org/wiki/Nondeterministic_Turing...

    In a deterministic Turing machine (DTM), the set of rules prescribes at most one action to be performed for any given situation. A deterministic Turing machine has a transition function that, for a given state and symbol under the tape head, specifies three things:

    en.wikipedia.org/wiki/Help:Displaying_a_formula

    Spaces within a formula must be directly managed (for example by including explicit hair or thin spaces). Variable names must be italicized explicitly, and superscripts and subscripts must use an explicit tag or template. Except for short formulas, the source of a formula typically has more markup overhead and can be difficult to read.

    For example, instead of A function f is even if and only if f(−x) = f(x) for all x; write A function f is even if f(−x) = f(x) for all x. If it is reasonable to do so, rephrase the sentence to avoid the use of the word "if" entirely. For example, An even function is a function f such that f(−x) = f(x) for all x

  9. Monus - Wikipedia

    en.wikipedia.org/wiki/Monus

    An example of a commutative monoid that is not naturally ordered is (, +,), the commutative monoid of the integers with usual addition, as for any , there exists such that + =, so holds for any ,, so is not a partial order. There are also examples of monoids that are naturally ordered but are not semirings with monus.
