  2. UTM parameters - Wikipedia

    en.wikipedia.org/wiki/UTM_parameters

    Urchin Tracking Module (UTM) parameters are five variants of URL parameters used by marketers to track the effectiveness of online marketing campaigns across traffic sources and publishing media. They were introduced by Google Analytics ' predecessor Urchin and, consequently, are supported out of the box by Google Analytics.

  3. Horizontal position representation - Wikipedia

    en.wikipedia.org/wiki/Horizontal_position...

    A position representation is a set of parameters used to express a position relative to a reference frame. When representing positions relative to the Earth, it is often most convenient to represent vertical position (height or depth) separately, and to use some other parameters to represent horizontal position. There are also several ...

  4. Universal Transverse Mercator coordinate system - Wikipedia

    en.wikipedia.org/wiki/Universal_Transverse...

    The projection from spheroid to a UTM zone is some parameterization of the transverse Mercator projection. The parameters vary by nation or region or mapping system. Most zones in UTM span 6 degrees of longitude, and each has a designated central meridian. The scale factor at the central meridian is specified to be 0.9996 of true scale for most ...

  5. Projected coordinate system - Wikipedia

    en.wikipedia.org/wiki/Projected_coordinate_system

    A projected coordinate system – also called a projected coordinate reference system, planar coordinate system, or grid reference system – is a type of spatial reference system that represents locations on Earth using Cartesian coordinates (x, y) on a planar surface created by a particular map projection. [1]

    Urchin Tracking Module parameters, used in Urchin, a Web analytics package that served as the base for Google Analytics and other analytics; Usability testing method, in interaction design; Unbounded transactional memory, transactional memory without bounds on transaction size or time

  7. Query string - Wikipedia

    en.wikipedia.org/wiki/Query_string

    A query string is a part of a uniform resource locator that assigns values to specified parameters.A query string commonly includes fields added to a base URL by a Web browser or other client application, for example as part of an HTML document, choosing the appearance of a page, or jumping to positions in multimedia content.

  8. Transverse Mercator projection - Wikipedia

    en.wikipedia.org/wiki/Transverse_Mercator_projection

    Near the central meridian (Greenwich in the above example) the projection has low distortion and the shapes of Africa, western Europe, the British Isles, Greenland, and Antarctica compare favourably with a globe. The central regions of the transverse projections on sphere and ellipsoid are indistinguishable on the small-scale projections shown ...

  9. Discrete-event simulation - Wikipedia

    en.wikipedia.org/wiki/Discrete-event_simulation

    The simulation must keep track of the current simulation time, in whatever measurement units are suitable for the system being modeled. In discrete-event simulations, as opposed to continuous simulations, time 'hops' because events are instantaneous – the clock skips to the next event start time as the simulation proceeds.
