... station in the United States switches over to the digital signal, ana log signals and television sets will still be in use, it will be hard for consumers to bow down and purchase 600 million new high definition television sets. HDTV, is known in the television industry as high definition television. HDTV is paving the way as a new medium waiting to emerge as the greatest thing to hit television since color. However it's not the 1950's and HDTV is already up and running in other markets. Japan's NHK broadcasting group used 1125/60 equipment and European ZDF broadcasters used 1250/50 equipment to cover the 1996 Atlanta games using the HDTV signal (Hitchen, 1 ...

... of the Constitution. First of all, censoring the Internet as a whole is not possible, so why even try? Cyberspace is the most decentralized form of communication today making policing the Internet a virtually futile task. Unlike television or radio, the Internet consists of thousands of individual computers and networks, with thousands of speakers, information providers and information users, and no centralized distribution point (ACLU vs. Reno Brief 1). No guards watch to see who goes where and if that place is appropriate. The Internet has grown to be a global network. Just because one country deems something inappropriate does not mean that anoth ...

... to technology. First the progress and power of industrial technology, second the domination and exploitation of Africa and Asia by Europeans. In the book The Tools of Empire, Headrick the author connects theses factors through many examples in history. Leading into the twentieth century even though many would like to fast forward into the dawn of electronics, there is still a major focus on technology in Africa and Asia. However, the transfer of technology is now steering away from dominating and leaning towards local adaptation. Africa and India experienced a deeper affect of technological transfer because they were conquered and colonized by Europe. The steamb ...

... a certain part of the computers memory, either relevant to the viruses purposes or at random. The Trojan horse is an innocent seeming program deliberately infects with a virus and circulated publicly. There is a cure for these viruses, though. These "cures" are called vaccines. A vaccine is a program that watches for typical things viruses do, halts them, and warns the computer operator. "Put a kid with the chicken pox together with a bunch of healthy kids and not all of them will get sick." But that is not the case with computer viruses. You see when a computer virus passes on a virus it never fails unless the computer is protected with a vaccine. A typ ...

... system will use a computer-based simulation and associated hardware to support the training of unit commanders and their battle staffs from battalion through theater-level as well as to support training events in educational institutions. Designed and built using modern computer technology, modern software engineering techniques, and validated algorithms and databases, it will allow units world-wide to train using their organizational equipment. A key feature of the system will be its use of technology to minimize the total Army's overhead associated with supporting training. The system will be designed to meet emerging Distributed Interactive Simulation (DIS) sta ...

... fast inner-city travel leading to lower airline fares, commercial air traffic has increased by 56 percent. Adding to the congestion and delay is increased commuter and regional air traffic. Those short distance flights take valuable landing slots that could be used for larger planes on more profitable, longer flights. With the maglev vehicles the shorter trips excluding access time can be cut a lot. With a study of 16 major corridors of travel, less than 300 miles in length, they studied how well the maglev vehicles could help, and in 10 out of the 16 the time could be cut at least slightly. Also the cost of a maglev trip will be less so that even with the lo ...

... individual states also have certain obligations to the operation and regulation of the different modes of transportation. Each mode is made up of primary subsystems. The subsystems of railroad transportation include freight trains and passenger trains. Freight trains are used to transport goods and materials between cities while passenger trains are used to transport people. Although freight trains are still used all across the nation, rail intercity freight has accounted for a decreasing share of the total ton mileage over the past 30 years. This is mostly due to the increase in truck transport. Rail passenger traffic had also declined over the years until ...

... required two innovations: the invention of a new building method called concrete vaulting and the organization of labor and capital on a large scale so that huge projects could be executed quickly after the plans of a single master architect. Roman concrete was a fluid mixture of lime and small stones poured into the hollow centers of walls faced with brick or stone and over curved wooden molds, or forms, to span spaces as vaults. The Mediterranean is an active volcanic region, and a spongy, light, tightly adhering stone called pozzolana was used to produce a concrete that was both light and extremely strong. The Romans had developed potsalana concrete about ...

The corporation Citibank also had an incident in 1995 in which Russian hackers stole over 10,000,000 dollars in fraudulent wire transfers by exploiting a hole in it's systems provision for money transfers. It cost the Italian government over 225,000 to repair a glitch in The Rome Air Force Base's system. The telecommunications giant of the west Southwestern Bell had a problem with a hacker named Christopher Schanot that cost them around 100,000 dollars.

... used today, invented by the French chemist Geoges Leclanche in the late 1860’s. At the time this invention was very important and helped the start of the industrial revolution. It allowed people with portable electricity. This popular invention was called the dry cell or flashlight battery. The Lechlanche cell is very similar to the dry cell we use today. The positive pole is a rode of carbon embedded in a black manganese dioxide (MnO2) and Carbon particles and the negative electrode is made of zinc. The electrolyte consists of a mixture of ammonium chloride and zinc chloride made into a paste. This sits in between the negative and positive electrodes, which acts ...
