... field. First and foremost is the fact that computer software is a very important educational tool. Students in high schools experience computers for the first time through games and other software. These help develop the ability to make quick and concrete decisions. The next step requires them to think more seriously about the machines. Secondary students learn the first steps in computer programming by creating simple programs. Here, the assistance of useful software is necessary. The computer software has many uses in the real world and is found virtually everywhere. The new generation of very fast computers introduces us to a new type of software. M ...
... propulsive power could be obtained by merely straightening out the surface of the airscrew blades. Attempts to utilize the “straight blade” propeller were made by balloonists. These contraptions were quite strange and hardly fulfilled their purpose of actually propelling the balloon. The basic propeller had evolved from the simple concepts of da Vinci, and was slowly becoming an effective means of aerial propulsion. To reach the next plateau of flight an increased knowledge of the propeller would be needed, and the mysteries of the propeller and mechanical power would need to be solved. These substantial tasks remained for aviation’s pioneers to tackle duri ...
... memory but out of sheer laziness. They used the two-digit system to cut down on the number of keystrokes needed to complete the programming, which helped them complete their task faster. It was discovered in the late 1980’s that this Y2K bug could cause computer systems to fail when the year 2000 rolled around because computers might fail to recognize that it is the year 2000 versus 1900. The problem is going to affect the whole world. How does affect the average person? It is possible that the electric companyies’ computers could crash, which could cause either blackouts or brownouts. It would mean no heat for your house and no way to store perishable item ...
... to be 15 or more decibels greater than the ambient noise. The hearing aid’s task is to acoustically or electronically compensate for both the neurological shortcomings of the hearing impaired person and the wide band increase inherent in any basic amplifier. Acoustic compensation can be carried out in a hearing aid microphone. Most hearing aids today utilize omnidirectional microphones, which pick up sound equally from all directions. This may be beneficial and practical in some cases, as in the completely in the canal (CIC) aid. The CIC aid uses the natural funneling of the auricle in order to focus sound directly into the instrument. Behind-the-ear (BTE) ...
... to traditional libraries. 4. The world-wide web (WWW), which is another component of the Net, can be used to "publish" material that would traditionally appear in journals, magazines, posters, books, television and even on film. 2. It is also essential to give a brief history on the internet. 3.The U.S. government is now trying to pass bills to prevent misuse of the Net. II. In order to understand the need for the ever-growing body of legislation, it is important to explore the controversy, and the current problems involved with the Net as it exists must be introduced. 1. The problem that concerns most people is offensive materials such as pornography. 2 ...
... and to maintain their position in the marketplace. As competition becomes more intense the formula for success becomes more difficult. Two particular things have greatly aided companies in their quests to accomplish these goals. They are the innovative software products of CAD/CAM and, last but not least, the World Wide Web. An important program has aided companies all over the world. Computer- aided design and computer-aided manufacturing (CAD/CAM) is the integration of two technologies. It has often been called the new industrial revolution. In CAD, engineers and designers use specialized computer software to create models that represent characterist ...
... to "programming" rules that the user must memorize, all ordinary arithmetic operations can be performed (Soma, 14). The next innovation in computers took place in 1694 when Blaise Pascal invented the first "digital calculating machine". It could only add numbers and they had to be entered by turning dials. It was designed to help Pascal's father who was a tax collector (Soma, 32). In the early 1800's, a mathematics professor named Charles Babbage designed an automatic calculation machine. It was steam powered and could store up to 1000 50-digit numbers. Built in to his machine were operations that included everything a modern general-purpose computer wou ...
... keyboards, mice and monitors being released all the time. The reason why the focus is on these products is that they are the parts of computer one interfaces with the most while working with computer. The subject of whether these ergonomic keyboards, mice, monitors and other products really work attracts a lot of regular computer users. Thus, studies dedicated to it have been done. This report is based on one of the studies about an ergonomic keyboard from a manufacturer called Kinesis. This study looks not only on the effect of the keyboard on the users' body by mean of electromyographic activity but also on the learning rate of the users changing to this new ...
... less crowded, and gave the people a newfound wealth and security. Steam engines made it easy to transport goods, the cotton gin made it easier to clean cotton, and made more money. Then technical schools began to develop, helping young people finish grammar school. Women also started working, they were very obedient and men started giving them more respect. Along with positive, were also negative. Most people worked twelve to fourteen hours a day, six days a week, they had to pay constant attention to the machines and risked losing limbs in the machines. Child labor was another problem, they usually worked from 6 am to 7 p.m., getting paid only 10 percent wages ...
... able to support all of their citizens and more, when in fact, nothing could be further from the truth. The reason that societies aid "undeveloped" countries is to gain access to their resources. Technological cultures are ones of mass consumption. As we have learned over the past few decades, are resources are limited and must be conserved properly. Tribal societies are a shining example of how to manage these resources, because they only use and eat what they need without wasting valuable resources. To demonstrate let us examine Bodley's study of the Maori tribe. The Maori tribe, settled in New Zealand during the age of expansion, allowed and even aided s ...
