These eight decades have seen enormous development of the country´s hydropower resources. Today‚ Norway´s consumption of electricity per capita is higher than that of any other country in the world. Most of the hydro-electric power stations are

FIBER TO THE HOME: THE NEW EMPOWERMENT abstract: In order to offer future higher bandwidth applications‚ the choice for a fiber to the home (FTTH) network seems to be the best candidate. Still‚ as the full deployment of a new FTTH network involves tremendous civil works and costs‚ only the highly profitable areas‚ e.g. city centers‚ are currently being installed. With the installation of such FTTH networks‚ all involved parties stay with many questions. What will the future bring on demands from

1958 and fabrication of low-loss optical fiber in 1970. When we hear of optical communications we all think of optical fibers‚ what I have for u today is AN OPTICAL COMMUNICATION SYSTEM WITHOUT FIBERS or in other words WIRE FREE OPTICS. Free space optics or FSO –Although it only recently and rather suddenly sprang in to public awareness‚ free space optics is not a new idea. It has roots that 90 back over 30 years-to the era before fiber optic cable became the preferred transport medium for

Optical Fiber Communication Course Code-MCS-616 1. Draw a diagram to approaches of optical communication. 2. Draw a block diagram of Light wave application areas. 3. Why do we use fiber computing? State the characteristics of optical fiber communication. Why we Use Optics for Computing? One of the theoretical limits on how fast a computer can function is given by Einstein’s principle that “signal cannot propagate

explore the cycle of copper through many chemical reactions. What we are going to do is take a piece of copper metal put it through a series of reactions that change it¡¦s state of matter and chemical formula‚ but in the end‚ we will return it to it¡¦s normal solid state. Determine the percentage yield (quantitative). Define what happen at level of electron for oxidation/reduction‚ double replacement‚ neutralization and decomposition. There are five reactions that the copper will go through. 1
