The Standard Industrial Classification (SIC) is a system for classifying industries by a four-digit code as a method of standardizing industry classification for statistical purposes across agencies. Established in the United States in 1937, it is used by government agencies to classify industry areas.

Silicon carbide (SiC) ceramic matrix composites (CMCs) are a specific application of engineering ceramic materials used to enhance aerospace applications such as turbine engine components and thermal protection systems. Due to exhibiting high temperature capabilities, low density, and resistance to oxidation and corrosion, SiC/SiC CMCs are ...
SIC codes identify what a business does. Over time there have been several different SIC systems used in the UK, with versions published in 1958, 1968, 1980, 1992, 1997, 2003 and 2007. These taxonomies have been adapted to cope with the changes in UK industry, The 1980 system was far more detailed in manufacturing, while the 2007 system is much ...
Electronic applications of silicon carbide such as light-emitting diodes (LEDs) and detectors in early radios were first demonstrated around 1907. SiC is used in semiconductor electronics devices that operate at high temperatures or high voltages, or both.
The XE expansion of SIC adds a 48-bit floating point data type, an additional memory addressing mode, and extra memory (1 megabyte instead of 32,768 bytes) to the original machine. All SIC assembly code is upwards compatible with SIC/XE. SIC machines have several registers, each 24 bits long and having both a numeric and character representation:
There are several manufacturing approaches to making silicon carbide fibers. [5] [6] The one with the longest historical experience, invented in 1975 and called the Yajima process, [7] uses a pre-ceramic liquid polymer that is injected through a spinneret to produce solidified green (unfired) fibers that go through a series of processing steps, including significant time in high temperature ...
The Refinitiv Business Classification (TRBC) is an industry classification of global companies. It was developed by the Reuters Group under the name Reuters Business Sector Scheme (RBSS), [1] [2] [3] was rebranded to Thomson Reuters Business Classification (TRBC) when the Thomson Corporation acquired the Reuters Group in 2008, forming Thomson Reuters, and was rebranded again, to The Refinitiv ...
