ISO 3166-1 alpha-2 – two-letter country codes which are also used to create the ISO 3166-2 country subdivision codes and the Internet country code top-level domains. ISO 3166-1 alpha-3 – three-letter country codes which may allow a better visual association between the codes and the country names than the 3166-1 alpha-2 codes.
In the following examples, red, green, and blue digits indicate how bits from the code point are distributed among the UTF-8 bytes. Additional bits added by the UTF-8 encoding process are shown in black. The Unicode code point for the euro sign € is U+20AC. As this code point lies between U+0800 and U+FFFF, this will take three bytes to encode.
This class of status code indicates the client must take additional action to complete the request. Many of these status codes are used in URL redirection. [2]A user agent may carry out the additional action with no user interaction only if the method used in the second request is GET or HEAD.
This Babcock & Wilcox nuclear steam generator moved in a special train (restricted to 20 mph) via the Penn Central Railroad and Southern Railway from Barberton, Ohio to a Duke Energy site in Oconee, S.C. This generator weights 1,140,000 lbs and is a record shipment for the Railroad at that time (1970). A once-through steam generator A VVER ...
The Morse code, as specified in the current international standard, International Morse Code Recommendation, ITU-R M.1677-1, [1] was derived from a much-improved proposal by Friedrich Gerke in 1848 that became known as the "Hamburg alphabet", its only real defect being the use of an excessively long code ( and later the equal duration code ...
The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [5] [6] [7] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [8] the pattern of position detection was found and determined by applying the least-used ratio (1:1:3 ...
A new type of heat-recovery steam generator based on the Benson boiler has operated successfully at the Cottam combined-cycle power plant in central England. The vertical tubing in the combustion chamber walls of coal-fired steam generators combines the operating advantages of the Benson system with the design advantages of the drum-type boiler.
The ANSI alphabetic state code is the same as the USPS state code except for U.S. Minor Outlying Islands, which have an ANSI code "UM" but no USPS code—and U.S. Military Mail locations, which have USPS codes ("AA", "AE", "AP") but no ANSI code.
