.... Radar works much like an echo. In an echo, a sound is sent out in all directions. When the sound waves find an object, such as a cliff face, they will bounce back to the source of the echo. If you count the number of seconds from when the sound was made to when the sound was heard, you can figure out the distance the sound had to travel. The formula is: (S/2) X 1100 = D (Half of the total time times 1100 feet per second equals the distance from the origin to the reflection point) Of course, radar is a much more complicated system than just somebody shouting and liste .....

.... the data they have access to on the black-market. Whether it be Ford Motor companies plan for the 1999 F-150 or spec sheets for the military's new bomber it happens everyday. Too by left is a drawing that illustrates the method that most Hackers use to take over your computer. Ever since the dial-up connection was invented anyone with a modem had the ability to wreck any one of thousands of computers. One of the most talked about forms of computer crime is computer viruses. A computer virus is a small but highly destructive program written by an unscrupulous compu .....

.... of the automotive world lies in computer controlled fuel injection systems. In order to understand the benefits of carburetors and fuel injectors, one must understand what they do. The carburetor is quite simply a fuel-metering device that operates under the logical and straightforward laws of physics. It has evolved over the years from a very simple and basic design to the complex and intricate models that are available today. Liquid fuel will not burn; it has to become vaporized by the carburetor before combustion can occur. If fuel is not vaporized then the liquid w .....

.... and the multiple computer / workstation network system (Donelan, 1993). Each with its corresponding unique architecture provides solutions to existing problems within the group dynamic at varying costs. To provide a better view of what each of the three architectures of GDSS's can provide, a brief description of each follows: The single-computer, software only system is the simplest and cheapest form of a GDSS. The system consists of a single computer running specialized GDSS software. The group involved in the decision making process can view all that is displayed on .....

.... connected together by telephone wires. It was first made by the military, "No one owns the Internet", to have a network with no centre. That way it could never be destroyed by nuclear war. Since then, universities have used it and it has evolved into what it is today. It is a library that contains mail, stories, news advertising, and just about everything else. "In a sense, freenets are a literacy movement for computer mediated communication today, as public libraries were to reading for an earlier generation." Now that the term "the net" is understood lets look at some sect .....

.... and better are the keys for words that society yearns for. The technological age is in full force and robots are in the main stream of this tidal wave. In the movie, Terminator, robots take over the world in their future. Are movies like these foretelling the future of mankind? Some Swiss scientists say that the end may be close (Kelly 1). An autonomous robot that learns from its environment sparked all of this "Armageddon" talk (Kelly 1). The robot learned not to bump into a barrier without any programming of that sort. This may not seem like a big deal, but this is a .....

.... which is the first hurdle, all the competitors are lined up together, one next to the other. So where do you go? You gravitate towards the brand names you already know -- the biggies." While Web site affordability has made it easier for companies like Phillip's to establish an Internet presence, the same is true for his competitors. Hence, a glut of small to medium-sized florists camp out on the Internet and fight to draw consumer attention to themselves and away from deep-pocketed and more recognizable competitors such as FTD and 800 Flowers. "There are now so many [flora .....

.... to disposable diapers. We can stop some of the garbage problem by recycling. Air conditioners are using up allot of our electricity. There are times in the summer when brown outs happen because if our excessive use of the air conditioners. Freon gets released into our environment. Today people are being kept alive longer and longer. People that have no chance of recovery are being kept alive on ventilators. This causes a great expense to society and an emotional stress on the family. Even though older people may beg to let them die medicine refuses to let them. This i .....
