... mixture causing the piston to fire downward at a very high speed. And finally, the exhaust stroke. This is when the piston moves up and pushes the burnt gas through a one-way valve, which then goes back into the cylinder head and then through the exhaust manifold and exhaust tubes and the leads out of the car. At 2200 RPM the entire four-stroke cycle is completed 18 times per second in each cylinder. The term V8 L6 and V6 refer to the number and configuration of engines cylinders. While the V8 is more popular for hot-rodding and for fast sports cars. The in-line six is common found in older cars that weren't that powerful. Inline fours and V6's are usuall ...
... technology and data retrieval systems and transactions, information has been given commercial value, especially with regards to the issue of who owns and controls this information. The information age has been a period that has allowed rights to privacy to beocme seriously jeopardized by new information technologies. Richard A. Spinello, has defined two distinct phases to the systematic erosion of information privacy. The first he calls the 'data base phase'. The emergence of sophisticatd data base technology in the early eighties made it possible to store and retrieve large amounts of information efficiently and economically. During ...
... Generally speaking, telecommuting is defined as spending at least one day out of a five day work week working in the home. Is one day home enough for the employee? Or, too little? How does the employer decide how many days to allow? Does the employee's job lend itself well to telecommuting? Some jobs, obviously, can't be accomplished using a telecommuting format. Does the employee have a good track record for working unsupervised? This relates back to readiness levels. An employee who isn't performing at a high readiness level should not even be considered as a candidate for telecommuting. All of these questions and many more must be answered ...
... medium must go through investigation and must be explored to see the full potential and how it affects society. In the 1940’s radio emerged as a strong medium, allowing thousands to hear news, entertainment, and even propaganda. Radio was new and was therefore forced to restrict its use of certain ideas and vocabulary. Years went by and a new form of media emerged: the device television, which was used to see pictures. Another new medium of communication except now with sight too. Television too was forced to restrict profanity, ideas that were not to be expressed, and information that was only for certain individuals. Both radio and television underwent ...
... products, not in sales. (Associated Press, March 13, 1997) According to survey results released by DeWitt Media in February 1997, almost two-thirds of all marketers have advertised on the Internet. 54% of those surveyed plan to increase their online advertising budgets in 1997. (Online Marketing Growing Strong, January 21, 1997) In addition, Advertising Age reported, "of the 100 Leading National Advertisers, 46 have purchased Web advertising" through July 1996, and nearly all have corporate Web sites. Many plan to make online advertising a line-item in their budgets for the first time this year. (Williamson, October 21, 1996) However ...
... bridges were used in the military expeditions of the Persian monarchs Darius I and Xerxes I. The Romans built many timber-trestle bridges. Surviving roman bridges, however usually have a level road supported on one or more semicircular stone arches. One of the most famous bridges would be The Pont du Gard at Nimes, France. It has three tiers of arches rising 155 feet above the Gard River, spans a distance of 855 feet. It was built in the late 1st century BC or the early 1st century AD. The cantilever bridge is characterized by spans that are supported not at the ends but near the center of the grider or truss. A suspension bridge 1010 feet long was designe ...
... replaced the copper with bronze, and the bronze with iron. This new saw was effective, but was not very specialized. It would react differently under different conditions. Eventually more complex designs were discovered. These new designs allowed for the precision cutting of hardwood, softwood, with the grain, against the grain, and even raked out the unwanted sawdust. These saws differed in the layout of the teeth. Instead of the jawbone patter the teeth were placed in a "left-right-angled" pattern, to rake the sawdust, and were placed at different distances depending on the substance being cut. As these handsaws progressed and continued to make the job of ...
... fraud committed by computer hackers costs three, four maybe even up to five billion dollars every year. Making an unwitting company pay for long distance calls is the most popular form of phone fraud today. The first step is to gain access to a private automated branch exchange known as a "PABX" or "PBX". One of these can be found in any company with twenty or more employees. A "PABX" is a computer that manages the phone system including it's voice mail. Once inside a "PABX" a hacker looks for a phone whose voice mail has not yet been programmed, then the hacker cracks it's access code and programs it's voice mail account to accept charges for long distance calls, ...
... courses in computer ethics, "There's hardly a business that's not using computers."1 This makes these questions all the more important for today's society to answer. There are also many moral and ethical problems dealing with the use of computers in the medical field. In one particular case, a technician trusted what he thought a computer was telling him, and administered a deadly dose of radiation to a hospital patient.2 In cases like these, it is difficult to decide who's fault it is. It could have been the computer programmer's fault, but Goodman asks, "How much responsibility can you place on a machine?"3 Many problems also occur when computers a ...
... A program must be written in an exact and precise way, with absolutely no errors, for a computer to understand and execute the directions. An example would be telling a computer to "reed data", a computer would not be able to execute this command. A simple misspelling of one word, can make a program worthless. Errors such as these must be identified and corrected before a program can successfully accomplish its assigned task. There are many types of jobs a can do. One is designing programs, or portions of programs. The primary job here is to analyse what the program is supposed to do, and write the code for it. Some problems need to be creatively solved. Most ...
