Type II codes are binary self-dual codes which are doubly even. Type III codes are ternary self-dual codes. Every codeword in a Type III code has Hamming weight divisible by 3. Type IV codes are self-dual codes over F 4. These are again even. Codes of types I, II, III, or IV exist only if the length n is a multiple of 2, 8, 4, or 2 respectively.
Hospital emergency codes are coded messages often announced over a public address system of a hospital to alert staff to various classes of on-site emergencies. The use of codes is intended to convey essential information quickly and with minimal misunderstanding to staff while preventing stress and panic among visitors to the hospital.
The concept of an electrostatic generator in which charge is mechanically transported in small amounts into the interior of a high-voltage electrode originated with the Kelvin water dropper, invented in 1867 by William Thomson (Lord Kelvin), [3] in which charged drops of water fall into a bucket with the same polarity charge, adding to the charge.

Thou Shalt Not, a 1940 photo by Whitey Schafer deliberately subverting some of the Code's strictures. In the 1920s, Hollywood was rocked by a number of notorious scandals, such as the murder of William Desmond Taylor and the alleged rape of Virginia Rappe by popular movie star Roscoe "Fatty" Arbuckle, which brought widespread condemnation from religious, civic and political organizations.
This table lists all two-letter codes (set 1), one per language for ISO 639 macrolanguage, and some of the three-letter codes of the other sets, formerly parts 2 and 3. Entries in the Scope column distinguish: Individual language; Collections of related languages; Macrolanguages; The Type column distinguishes: Ancient languages (extinct since ...
The RM(0, m) code is the repetition code of length N =2 m and weight N = 2 m−0 = 2 m−r. By 1 (,) = and has weight 1 = 2 0 = 2 m−r. The article bar product (coding theory) gives a proof that the weight of the bar product of two codes C 1, C 2 is given by
