The Lark Ascending is a work by the English people English composer Ralph Vaughan Williams , inspired by George Meredith s 122 line poem of the same name about the skylark . The work was written in two versions violin and piano , written in 1914 and violin and orchestra , written in 1920. The orchestral version is the one that is almost always heard now. It is one of the most popular pieces in the Classical repertoire among British listeners. Vaughan Williams sketched the work while watching troop ships cross the English Channel at the outbreak of the World War I First World War . A small boy observed him making the sketches and, thinking he was jotting down a secret code, informed a police officer, who subsequently arrested the composer.

Artwork image file Ascending and Descending.jpg image size 275px title Ascending and Descending artist M. C. Escher year 1960 type Lithography lithograph height 35.5 width 28.5 Italic title Ascending and Descending is a Lithography lithograph print by the Netherlands Dutch artist M. C. Escher which was first printed in March 1960. The original print measures 14 x 11 1 4 . The lithograph depicts a large building roofed by a never ending staircase . Two lines of identically dressed men appear on the staircase, one line ascending whilst the other descends. Two figures sit apart from the people on the endless staircase one in a secluded courtyard, the other on a lower set of stairs. While most two dimensional artists use relative proportions to create an illusion of depth, Escher here and elsewhere uses conflicting proportions to create the visual paradox. Ascending and Descending was influenced by, and is an artistic implementation of, the Penrose stairs , an impossible object Lionel Penrose had first published his concept in the February, 1958 issue of the British Journal of Psychology . Escher developed the theme further in his print Waterfall M. C. Escher Waterfall , which appeared in 1961. The two concentric processions on the stairs use enough people to emphasise the lack of vertical rise and fall. In addition, the shortness of the tunics worn by the people makes it clear that some are stepping up and some are stepping down. The structure is embedded in human activity. By showing an unaccountable ritual of what Escher calls an unknown sect, Escher has added an air of mystery to the people who ascend and descend the stairs. Therefore, the stairs themselves tend to become incorporated into that mysterious appearance. There are free people and Escher said of these recalcitrant individuals refuse, for the time being, to take part in the exercise of treading the stairs. They have ... 0 8109 6720 0. M. C.

Orphan date February 2009 In telecommunication s, node to node data transfer is the movement of data from one node networking node of a Telecommunications network network to the next. In the OSI model it is handled by the lowest two layers, the data link layer and the physical layer . In most communication systems, the transmitting point applies source coding , followed by channel coding , and lastly, line coding . This produces the baseband signal. Some systems then use modulation to multiplex many baseband signals into a broadband signal. The receiver un does these transformations in reverse order demodulation, trellis decoding, error detection and correction, decompression . Some communication systems omit one or more of these steps, or use techniques that combine several of these steps together. For example, a Morse code transmitter combines source coding, channel coding, and line coding into one step, typically followed by an amplitude modulation step. Barcode s, on the other hand, add a checksum digit during channel coding, then translate each digit into a barcode symbol during line coding, omitting modulation. Source coding See main article Data compression Source coding is the elimination of redundancy to make efficient use of storage space and or transmission channels. Examples of source coding are Huffman coding Morse code Binary coding Channel coding See main article Error correction and detection . In digital telecommunication s, channel coding is a pre transmission mapping applied to a digital signal or data file, usually designed to make error correction or at least Error detecting code error detection possible. Error correction is implemented by using more numerical digit digit s bit s in case of a binary channel than the number strictly necessary for the samples, and having the receiver compute the most likely valid message that could have resulted in the received one. Types of channel coding include Parity check s Hamming code Reed Muller code Reed Solomon ... more details

It is the hardware that is connected to the mobile phone network that communicates directly with mobile handsets. In contrast with GSM base stations, Node B uses WCDMA TD SCDMA as the air interface technology. As in all cellular systems, such as UMTS and GSM , the Node B contains radio frequency transmitter s and the receiver s used to communicate directly with mobile devices, which move freely around it. In this type of cellular network, the mobile devices cannot communicate directly with each other but have to communicate with the Node B. Traditionally, the Node Bs have minimum functionality, and are controlled by an RNC Radio Network Controller . However, this is changing with the emergence of High Speed Downlink Packet Access HSDPA , where some logic e.g. retransmission is handled on the Node B for lower response times.

Refimprove date January 2007 In electrical engineering , node refers to any point on a circuit where two or more circuit elements meet. For two nodes to be different, their voltages must be different. Without any further knowledge, it is easy to establish how to find a node by using Ohm s Law V IR. When looking at circuit schematics, ideal wires have a resistance of zero. Since it can be assumed that there is no change in the potential across any part of the wire, all of the wire in between any components in a circuit is considered part of the same node. ref Smith, Ralph J. 1966 , Circuits, Devices and Systems , Chapter 2, John Wiley & Sons, Library of Congress Catalog Card No. 66 17612 ref Voltage Current Resistance br since voltage is a measure of potential difference the voltage between any two parts of the same node is br br V sub ab sub Current 0 So at any two points on the same node, the change in potential difference is 0. Therefore, throughout the entire node the voltage is the same. Image Nodes2.svg frame right Each different color in circuit above is a different node In this circuit diagram the voltage in the green node is the same throughout, likewise, the voltages in the blue node and the red node are the same throughout. In most cases, the voltage difference between one point on a piece of metal such as a copper wire , and the voltage at another point of the same piece of metal or on other bits of metal with metal to metal contact with the first piece of metal, is so small that it is usually considered insignificant. So every bit of that connected metal can be considered part of the same node.
