the mobile phone system in Europe. This group was called Group Special Mobile (GSM). For the next ten years the GSM group outlined standards‚ researched technology and designed a way to implement a pan-European mobile phone network. In 1989 work done by the GSM group was transferred to the European Telecommunication Standards Institute (ETSI). The name GSM was transposed to name the type of service invented. The acronym GSM had been changed from Group Special Mobile to Global Systems Mobile Telecommunications

__ Lip Reading __ A brief history of lip-reading: Although lip-reading (also called speech-reading) is done subconsciously since the very beginning of human existence. It’s been particularly put into use for more helpful reasons. Mainly in communication strategies‚ as in aiding hearing-impaired and deaf people in communicating with the world and also helping normal people recognize words in noisy environments. However‚ it is very likely that the best lip reader can only catch 50% of the words

first stone in the field of communication using different tools regardless of distance. He invented first wired base telephony equipment. It was the solution for the voice communication for the people how far apart they are. After this radio based communication systems Era started. It was an extension of wired based networks. In the beginning it was developed for some special purposes like military and police usage. With the passage of time these systems emerged to allow common peoples to communicate

Understanding Earth: Running Shoes as Drift Meters- Just Do It Unit 5- The Global Ocean: Box 14.1. In this article I learned that any floating object can operate as a drift meter as long as it is known where the object submitted the water and where it was reclaimed. If these times are recognized‚ the route of the object can then be concluded assisting the determination of the speed and movement of currents. Numerous ships have lost cargo at sea‚ but the incidents releasing Nike

Abstract This is an experiment about procedures of calibration of a Coriolis mass flow meter. To do the experiment‚ water is pumped from a reservoir and its flow rate is set by a tap‚ the height drop is examined by eye and the time is recorded for a period during the flow. This procedure is arranged for the calibration of the Coriolis meter by comparing the calculated mass flow and the read value. Although‚ it is a reasonable aspect for the calibration which is comparing digital and analog measurement

feeder. Through an iterative process‚ this can be accomplished using a series of calculations. To achieve this goal‚ the simulation package Matlab was used as the driving force behind the programming and calculating. Discussion 2.1 Individual Segment Modeling To simulate the feeder‚ the first thing needed is a model of each line segment. To construct this model‚ code can be written that computes the distances between conductors by using the configurations and conductor values given for each line
