C++23, formally ISO/IEC 14882:2024 [1], is the current open standard for the C++ programming language that follows C++20.The final draft of this version is N4950. [2] [3]In February 2020, at the final meeting for C++20 in Prague, an overall plan for C++23 was adopted: [4] [5] planned features for C++23 were library support for coroutines, a modular standard library, executors, and networking.
The Infrared Optical Telescope Array (IOTA) was a stellar interferometer array. IOTA began with an agreement in 1988 among five Institutions, the Smithsonian Astrophysical Observatory, Harvard University, the University of Massachusetts Amherst, the University of Wyoming, and MIT/Lincoln Laboratory, to build a two-telescope stellar interferometer for the purpose of making fundamental ...
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
is a subset of , and is a superset of .. In mathematics, if is a subset of , then the inclusion map is the function that sends each element of to , treated as an element of ::, =.
The moving ranges involved are serially correlated so runs or cycles can show up on the moving average chart that do not indicate real problems in the underlying process. [ 2 ] : 237 In some cases, it may be advisable to use the median of the moving range rather than its average, as when the calculated range data contains a few large values ...

ITU-R Rec. BT.2111 [30] and ARIB STD-B72 [31] further added versions with PQ / HLG HDR transfer functions and wide color gamut (BT.2020), which additionally have 100% saturated colors at the top and BT.709 bars at right bottom and left bottom; the 75% gray horizontal bar in the middle is changed to grayscale stair steps.
CIE standard illuminant A is intended to represent typical, domestic, tungsten-filament lighting. Its relative spectral power distribution is that of a Planckian radiator at a temperature of approximately 2856 K. CIE standard illuminant A should be used in all applications of colorimetry involving the use of incandescent lighting, unless there ...
