A comparison between a typical normalized M cone's spectral sensitivity and the CIE 1931 luminosity function for a standard observer in photopic vision. In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color space).
CIELAB is used by Datacolor spectrophotometers, including the related color difference calculations. CIELAB is used by the PantoneLive library. CIELAB is used extensively by X-Rite as a color space with their hardware and software color measuring systems. CIELAB D50 is available in Adobe Photoshop, where it is called "Lab mode". [15] [16]
[D65] is intended to represent average daylight and has a correlated colour temperature of approximately 6500 K. CIE standard illuminant D65 should be used in all colorimetric calculations requiring representative daylight, unless there are specific reasons for using a different illuminant.
The Common Electrical I/O (CEI) Interoperability Agreement published by the OIF defines the electrical and jitter requirements for 3.125, 6, 11, 25-28, and 56 Gbit/s SerDes interfaces. This CEI specification has defined SerDes interfaces for the industry since 2004, and it has been highly influential.
IEC 60949 Calculation of thermally permissible short-circuit currents, taking into account non-adiabatic heating effects; IEC 60950 Information technology equipment – Safety; IEC 60951 Nuclear power plants – Instrumentation important to safety – Radiation monitoring for accident and post-accident conditions; IEC 60952 Aircraft batteries
The Optical Internetworking Forum (OIF) has published the Common Electrical I/O (CEI) Interoperability Agreements (IAs), that have defined six generations of the electrical interface of SerDes, at 3.125, 6, 10, 28, 56 and 112 Gb/s. The OIF has announced new projects at 224 Gb/s.
2 Ce + 3 I 2 → 2 CeI 3. It is also formed when cerium reacts with mercury(II) iodide at high temperatures: [2] 2 Ce + 3 HgI 2 → 2 CeI 3 + 3 Hg. Structure.
It is a special case of the configuration interaction method in which all Slater determinants (or configuration state functions, CSFs) of the proper symmetry are included in the variational procedure (i.e., all Slater determinants obtained by exciting all possible electrons to all possible virtual orbitals, orbitals which are unoccupied in the electronic ground state configuration).
