The skew binary numbersystem is a numbersystem in which the nth digit has a value of math 2 n 1 1 math and each digit has a value of 0, 1, or 2. Each number can be written uniquely in skew binary canonical form where there is only one instance of the digit two, which must be the first non zero digit. The advantage of skew binary could be made by exploiting the fact that math 2 2 n 1 1 1 2 n 2 1 math . This means we can simply increment the skew binary number that contains a two by setting it zero and incrementing the next digit from zero to one or one to two. ref http www.cl.cam.ac.uk teaching 2004 IntroFuncProg lecture08.html skew binary numbers ref Skew binary numbers find applications in skew binomial heap s, a variant of binomial heap s that support worst case O 1 insertion, and in skew binary random access lists , a purely functional data structure .

The Nashville NumberSystem is an informal method of Transcription music transcribing music by denoting the scale degree on which a Chord music chord is built. It was developed by Neal Matthews, Jr. in the late 50s as a simplified system for The Jordanaires to use in the studio and further developed by Charlie McCoy . It resembles the Roman numeral and figured bass systems traditionally used to transcribe a chord progression . By writing chords as numbers, music may be Transposition music transposed easily. As a simple system of transcription, it can be used with only a rudimentary background in music theory . Improvisation structures can be quickly explained using numbers and chord changes can be communicated mid song by holding up the corresponding number of fingers. The system is flexible, and can be embellished to include more information such as chord color or to denote a bass note in an inverted chord .

A residue numbersystem RNS represents a large integer using a set of smaller integers, so that computation may be performed more efficiently. It relies on the Chinese remainder theorem of modular arithmetic for its operation, a mathematical idea from Sun Tzu mathematician Sun Tsu Suan Ching Master Sun s Arithmetic Manual in the 4th century AD. Defining a residue numbersystem A residue numbersystem is defined by a set of N integer constants, m sub 1 sub , m sub 2 sub , m sub 3 sub , ... , m sub N sub , referred to as the moduli . Let M be the least common multiple of all the m sub i sub . Any arbitrary integer X smaller than M can be represented in the defined residue numbersystem as a set of N smaller integers x sub 1 sub , x sub 2 sub , x sub 3 sub , ... , x sub N sub with x sub i sub X Modulo operation modulo m sub i sub representing the residue class of X to that modulus. Note that for maximum representational efficiency it is imperative that all the moduli are coprime that is, no modulus may have a common factor with any other. M is then the product of all the m sub i sub . For example RNS 4 2 has non coprime moduli, resulting in the same representation for different values. ref Parhami, Computer Arithmetic, Algorithms and Hardware Design ref 3 decimal 3 1 sub RNS 4 2 sub 7 decimal 3 1 sub RNS 4 2 sub Operations on RNS numbers Once represented in RNS, many arithmetic operations ....

Context date October 2009 A System Identification Number SID is broadcast by one or more Base Station s to identify a cellular network in a certain area usually contiguous . It is globally unique within Advanced Mobile Phone System AMPS , Digital AMPS TDMA or CDMA networks the first two systems are essentially obsolete . This number sometimes has conflicts see IFAST . SID Codes These codes are broadcast as 15 bit values but transmitted as 16 bits by core network protocols. They can be listed within a wireless device to show preference for one network over another. The additional bit in core network protocols allows the range of codes above 32,767 to be used for internal purposes, such as segregating billing records within a large area identified by a single broadcast SID. TIA TR 45.2 assigned ranges to every country extant in the 1980s and national regulators assigned individual numbers. IFAST took over in 1997. This number space is 90 utilized for country ranges, however many countries do not use all of their allocated codes so the majority of codes are not used. SIDs are assigned to every carrier e.g., Verizon, Sprint, Alltel by national regulators or IFAST . SIDs are programmed into the phone when you purchase them. A phone will maintain a list of preferred systems identified by their SID code. The SID may also modify some signaling messages that are transmitted by mobiles e.g. reducing the amount of information transmitted by home mobiles . How SIDs work When the phone is turned on, it listens for a signal. If it receives a signal, it looks at the SID being carried by the signal , and compares it with the one that is stored in the phone. Originally, in analog systems, the mobile would simply turn on the roaming indicator if the SID was not the single value stored in the phone. However, with CDMA systems the Preferred Roaming List Preferred Roaming List PRL PRL is responsible for determining which areas a mobile can roam into. Base Station Base stations may also broadcast ... more details
The Number One Crossbar Switching System , or 1XB switch , was the primary urban local telephone exchange design used by the Bell System in the mid 20th century. Its switch fabric topology was based on the earlier urban panel switch system, which, in turn, was based on the turn of the century Divided Multiple Telephone switchboard Switchboard . Thus, it had separate incoming and outgoing sections. However, lines appeared only on the Line Link Frame LLF , rather than requiring a multi wire connection to two different sections as in a panel switch. The LLF uniting the telephone line circuit at its column and switch simplified administration. The first 1XB was the PR7 exchange at Troy Avenue in Brooklyn, New York in 1937. ref http www.thg.org.uk special interest Crossbar.html Telecommunications Historical Group UK Peter Walker on history of Crossbar ref Subscriber sender For outgoing calls, the Line Link Frame acted like the Line Finder of the panel switch, autonomously connecting the line to a junctor , which corresponded to the cord circuit of the old cord telephone switchboard . As in the panel switch, the Sender then found the chosen junctor and supplied dial tone . Like the panel switch, the 1XB common control was based on a complex, versatile Sender circuit. The Sender was able to accept Dial Pulses and in later models dual tone multi frequency signaling DTMF .

The Number Five Crossbar Switching System or 5XB switch , designed by Bell Labs and made by Western Electric , was in use in Bell System telephone exchange s from 1948 to the 1980s. Its principal use was as a Class 5 telephone switch , though variants were used as combined PSTN class 4 5 in rural areas and as a Telegraphy Telex TWX switch. 5XB was originally intended to bring the benefits of crossbar switch ing to small towns with only a few thousand telephone lines . The earlier 1XB switch 1XB urban crossbar was impractically expensive in small installations, and had difficulties handling large trunk groups. 5XB was converted to wire spring relay s in the 1950s and otherwise upgraded in the 1960s to serve exchanges with tens of thousands of lines. The final 5A Crossbar variant in the early 1970s returned to its roots, being available only in sizes of 960 and 1920 lines, and generally delivered on one pallet rather than assembled on site as usual for larger exchanges.
