- 2101: History of the Propeller
- ... propeller represents the highest sophistication in aerodynamics, mechanical engineering and structural design. This report will touch on the history of the propeller, from early pioneers/experiments, advancement during/after the war, all the way up to current applications of the propeller. The creation of the propeller can be traced back to Leonardo da Vinci. Da Vinci’s “helical screw” helicopter is ... and structural reliability. These advancements led to the development of the first generation of well-designed propellers. One of the first designs was the “Integrale”, developed by Lucien Chauviere, the world’s first industry standard propeller manufacturer. By 1910, the number of propeller producers multiplied, and numerous advancements were made. While most of the manufacturers were focusing on wooden propellers, a ... the efficiency of any aerodynamic device rises as the amount of air it acts upon increases and the velocity of that air decreases. These theories were expanded during WWI. The war brought much advancement to the propeller. Stronger materials were created through “bonding” which made propellers compatible with the larger, more powerful engines. Propeller balancing techniques were developed, which greatly ...
- 2102: America and the Computer Industry
- ... provided a means of input, output, and memory storage on a massive scale. For more than 50 years following their first use, punched-card machines did the bulk of the world's business computing and a good portion of the computing work in science (Chposky, 73). By the late 1930s punched-card machine techniques had become so well established and reliable ... Howard Hathaway Aiken, in collaboration with engineers at IBM, undertook construction of a large automatic digital computer based on standard IBM electromechanical parts. Aiken's machine, called the Harvard Mark I, handled 23-digit numbers and could perform all four arithmetic operations. Also, it had special built-in programs to handle logarithms and trigonometric functions. The Mark I was controlled from prepunched paper tape. Output was by card punch and electric typewriter. It was slow, requiring 3 to 5 seconds for a multiplication, but it was fully ...
- 2103: The Arrival Of The Internet
- ... 100 million U.S. citizens that use the Internet today and this number is growing exponentially.(Consol, 26) This limitless technology has provided a means for people anywhere in the world to communicate with each other, sending and receiving information via the Internet. With this newfound technology comes new dangers and problems. The hazards of the Internet range from cyber crimes ... get the information to its destination. It's much like a spider web. You can cut many of the strands and it still hold together. This is how the phrase "World Wide Web" came into existence. The Internet has grown and improved over the years; from a cold war project, to a medium for exchanging ideas and information worldwide. As a cold War project, the Internet was developed to provide reliable communication during a nuclear attack. The Internet ...

- 2105: A Technical Analysis of Ergonomics and Human Factors in Modern Flight Deck Design
- A Technical Analysis of Ergonomics and Human Factors in Modern Flight Deck Design I. Introduction Since the dawn of the aviation era, cockpit design has become increasingly complicated owing to the advent of new technologies enabling aircraft to fly farther and faster more efficiently ... view as seen from inside the cockpit, having the horizon move behind a fixed miniature airplane, or as it would be seen from outside the aircraft. Until the end of World War I, aircraft were manufactured using both types of display. This caused confusion among pilots who were familiar with one type of display and were flying an aircraft with the ...
- 2106: Technology In Our Society
- Technology In Our Society No doubt, technology is increasingly important in the modern world. It is amazing how fast technology has been developed. Nearly every major advance was invented in the last century. These invention are always planned for a positive result, however the ... It is a remarkable increase. In the near future, hopefully, genetic testing will be employed to reveal potential health risks. It is a positive effect of technology in the modern world. Another useful source for the effects of technology in our world is the documentary. On 23 April 1996, SBS broadcasted a film entitled "Weapon: A Battle for Humanity". It recorded that landmines and laser weapons are devils. Evidently, mines do ...
- 2107: Brief History of Library Automation: 1930-1996
- ... implemented for use in library circulation and acquisitions. During the 30's and early 40's progress on computer systems was slow which is not surprising, given the Depression and World War II. In 1945, Vannevar Bush envisioned an automated system that would store information, including books, personal records and articles. Bush(1945) wrote about a hypothetical "memex" system which he described ... By the mid-60's, computers were being used for the production of machine readable catalog records by the Library of Congress. Between 1965 and 1968, LOC began the MARC I project, followed quickly by MARC II. MARC was designed as way of "tagging" bibliographic records using 3-digit numbers to identify fields. For example, a tag might indicate "ISBN," ...
