  2. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    For data requests that fall between the table's samples, an interpolation algorithm can generate reasonable approximations by averaging nearby samples." [8] In data analysis applications, such as image processing, a lookup table (LUT) can be used to transform the input data into a more desirable output format. For example, a grayscale picture ...

  3. Integral field spectrograph - Wikipedia

    en.wikipedia.org/wiki/Integral_field_spectrograph

    The brute force approach would have been to build huge spectrographs feeding gigantic detector arrays. Instead, the two Panoramic IFS in operation by 2022, Multi-unit spectroscopic explorer (MUSE) and Visible Integral-field Replicable Unit Spectrograph (VIRUS), [28] are made of respectively 24 and 120 serial-produced optical IFS. This results ...

    en.wikipedia.org/wiki/Integrated_Forecast_System

    It comprises a spectral atmospheric model with a terrain-following vertical coordinate system coupled to a 4D-Var data assimilation system.In 1997 the IFS became the first operational forecasting system to use 4D-Var. [2] Both ECMWF and Météo-France use the IFS to make operational weather forecasts, but using a different configuration and resolution (the Météo-France configuration is ...

    IFS fractals are more related to set theory than fractal geometry. [1] They were introduced in 1981. IFS fractals, as they are normally called, can be of any number of dimensions, but are commonly computed and drawn in 2D. The fractal is made up of the union of several copies of itself, each copy being transformed by a function (hence "function ...

    en.wikipedia.org/wiki/Internal_Family_Systems_Model

    The Internal Family Systems Model (IFS) is an integrative approach to individual psychotherapy developed by Richard C. Schwartz in the 1980s. [ 1 ] [ 2 ] It combines systems thinking with the view that the mind is made up of relatively discrete subpersonalities , each with its own unique viewpoint and qualities.

    One should not confuse four-valued mathematical logic (using operators, truth tables, syllogisms, propositional calculus, theorems and so on) with communication protocols built using binary logic and displaying responses with four possible states implemented with Boolean-like type of values : for instance, the SAE J1939 standard, used for CAN ...
