41Emergency Broadcast System — For the record label, see Emergency Broadcast System Records. For the multimedia group, see Emergency Broadcast Network. The Emergency Broadcast System (EBS) was an emergency warning system in the United States, used from 1963 to 1997, when it… …
42Dual code — For players of both rugby codes, see List of dual code rugby internationals. In coding theory, the dual code of a linear code is the linear code defined by where is a scalar product. In linear algebra terms, the dual code is the annihi …
43Universal code (data compression) — In data compression, a universal code for integers is a prefix code that maps the positive integers onto binary codewords, with the additional property that whatever the true probability distribution on integers, as long as the distribution is… …
44United Kingdom Warning and Monitoring Organisation — The United Kingdom Warning and Monitoring Organisation (UKWMO) was a British civilian organisation operating between 1957 and 1992 to provide the authorities with data about nuclear explosions and forecasts of likely fallout profiles across the… …
45Noisy-channel coding theorem — In information theory, the noisy channel coding theorem (sometimes Shannon s theorem), establishes that for any given degree of noise contamination of a communication channel, it is possible to communicate discrete data (digital information)… …
46Error exponent — In information theory, the error exponent of a channel code or source code over the block length of the code is the logarithm of the error probability. For example, if the probability of error of a decoder drops as e – n α, where n is the block… …
47долговременная маркировка — 04.02.27 долговременная маркировка [ permanent marking]: Изображение, полученное с помощью интрузивного или неинтрузивного маркирования, которое должно оставаться различимым, как минимум, в течение установленного срока службы изделия. Сравнить с… …

48Entropy encoding — In information theory an entropy encoding is a lossless data compression scheme that is independent of the specific characteristics of the medium. One of the main types of entropy coding creates and assigns a unique prefix free code to each… …
49Night of the Long Knives — For other uses, see Night of the Long Knives (disambiguation). Although the …
50Binary symmetric channel — A binary symmetric channel (or BSC) is a common communications channel model used in coding theory and information theory. In this model, a transmitter wishes to send a bit (a zero or a one), and the receiver receives a bit. It is assumed that… …
