...binary prefixes A set of prefixes for binary powers designed to be used in data processing and data transmission contexts. They were suggested in 1998 by the International Electrotechnical Commission ( IEC ) as a way of resolving the ambiguity in use of kilo-, mega-, giga-, etc., in computing. In scientific usage, these prefixes indicate 10 3 , 10 6 , 10 9 , etc. ( see SI units ). In computing, it became common to use the prefix ‘kilo-’ to mean 2 10 , so one kilobit was 1024 bits (not 1000 bits). This was extended to larger prefixes, so ‘mega-’ in...

...suggested by the lack of essential stage directions , the irregularity of the speech-prefixes , and occasional false starts and second thoughts. The second and the third quartos emended obvious compositorial mistakes and introduced new ones, which were then inherited by the 1623 Folio edition, set from an annotated copy of Q3. The main alterations introduced into the 1623 edition, including more extensive stage directions, act division , normalized speech-prefixes, and a whole new scene, the so-called fly-killing scene in Act 3, clearly derive from a...

...Prefixes . English is a major debtor to the world's other languages, especially to Latin and Greek. The extent of borrowing from the classical languages is mind-boggling. One of the early editors of the OED , the great Henry Bradley , put it this way: “The Latin element in modern English is so great that there would be no difficulty in writing hundreds of consecutive pages in which the proportion of words of native English and French etymology, excluding particles, pronouns, and auxiliary and substantive verbs, would not exceed five per cent of the...

...encoding A (usually) binary encoding of the elements of a finite set, A , A = { a 1 , a 2 , … , a n } where each element a i in A has an assumed probability, p i , of occurring in a message. The binary encoding satisfies the prefix property and is such that messages will have a minimum expected length. Thus an element a i with a high probability of occurring in a message is encoded as a short binary string while an element with a low probability of occurring is encoded with a longer string.

This arises as a matter of convenient terminology for memories and similar entities organized on a binary basis. (But see below re communication channels.) Concerned at the widespread use of SI decimal prefixes for nearby but distinct binary multipliers, the International Electrotechnical Committee in 1999 adopted as an international standard (outside of the SI) a range of revised multiplier prefixes, derived from those of the SI, implying the...

Observations of interstellar dispersion ( 2 ) and the Faraday effect in pulsars provides information about the distribution of free electrons and magnetic fields in the Milky Way. Pulsars are denoted by the prefix PSR followed by the approximate position in right ascension (4 digits) and declination (2 or 3 digits), usually for equinox 1950.0. The figures may be preceded by B if the coordinates are for epoch 1950.0, or J for epoch 2000.0. http://www.atnf.csiro.au/research/pulsar/psrcat/ ...

...between root and D-affix, and consequently a fundamental difference between D-morphology and compounding, is argued explicitly by Selkirk 1982 , but has been denied by Höhle 1982 . However, there is a widely shared view that the distinction between prefix and suffix is not a categorial one; prefixation and suffixation are assumed to be governed by the same types of rules. The restriction of D-morphology to D-affixes presupposes an essential difference between affixation and other techniques involved in morphological processes, such as conversion,...

...delinking of [labial] associated with the prefix: The motivation for this delinking is the Obligatory Contour Principle (OCP), which stipulates that adjacent identical elements are prohibited (Goldsmith 1976 , McCarthy 1986 , Yip 1988 ). This analysis of dissimilation has two important consequences: (i) features are represented on separate phonological tiers; and (ii) features that are inactive in dissimilation are unspecified at the time when the OCP is applied. The [labial] specification of the prefix is adjacent to the [labial] of the stem-final...
