Whistle

An aerodynamic whistle (or call) is a simple aerophone, an instrument which produces sound from a stream of gas, most commonly air. It may be mouth-operated, or powered by air pressure, steam, or other means. Whistles vary in size from a small slide whistle or nose flute type to a large multi-piped church organ.

Whistles have been around since early humans first carved out a gourd or branch and found they could make sound with it. In prehistoric Egypt, small shells were used as whistles. Many present day wind instruments are inheritors of these early whistles. With the rise of more mechanical power, other forms of whistles have been developed.

One characteristic of a whistle is that it creates a pure, or nearly pure, tone. There are many ways to create pure tones, but we restrict the descriptions here to what are called aerodynamic whistles. Strictly speaking, they are fluid mechanical whistles since they occur in gases, such as air or steam, as well as in liquids, such as water. The only difference between them is the fluid density and the sound speed.

Whistle!

Whistle! (ホイッスル!, Hoissuru!) is a Japanese manga series written and illustrated by Daisuke Higuchi, which was adapted into a 39-episode anime television series, broadcast exclusively by Animax across Japan and South Korea.

The manga, which is association football-themed, was published in Japan in Shueisha's Weekly Shōnen Jump, and in English by Viz Media under the Shonen Jump label. The manga was written in homage to the 1998 and 2002World Cup Finals tournaments which took place in France and Japan/South Korea respectively.

Plot

Whistle! is about a middle school boy named Shō Kazamatsuri. He transfers from Musashinomori School to Sakura Jōsui Junior High School for better hopes to make the soccer team, since he never got a game at his old school due to his small stature. Yūko Katori, his teacher, introduces him as a former star of the famed Musashinomori team, causing his classmates to be wrongly ecstatic. Right after that, one of the players, Tatsuya Mizuno, reveals that he was never a regular. In other words, since he never got the chance to play, Shō is a poor player. Shō struggles to improve his skill so he can make the team at his new school and to ignore the drastic disadvantage he has due to his height.

ICT 1301

The ICT 1301 and its smaller derivative ICT 1300 were early business computers from International Computers and Tabulators. Typical of mid-sized machines of the era they used core memory, drum storage and punched cards, but they were unusual in that they were based on decimal logic instead of binary.

The 1301 was designed by an ICT and GEC joint subsidiary, Computer Developments Limited (CDL) at GEC's Coventry site.

The 1301 was the main machine in the line. Its main memory came in increments of 400 words of 48 bits (12 decimal digits) plus two parity bits. The maximum size was 2,000 words. It was the first ICT machine to use core memory.

Backing store was magnetic drum and optionally one inch, half inch or quarter inch wide magnetic tape. Input was from 80 column punched cards and optionally 160 column punched cards and punched paper tape. Output was to 80 column punched cards, line printer, and optionally to punched paper tape.

The machine ran at a clock speed of 1 MHz and its arithmetic logic unit (ALU) operated on data in a serial-parallel fashion—the 48-bit words were processed sequentially four bits at a time. A simple addition took 21 clock cycles; hardware multiplication averaged 170 clock cycles per digit; and division was performed in software.

ICT 1900 series

ICT 1900 was the name given to a series of mainframe computers released by International Computers and Tabulators (ICT) and later International Computers Limited (ICL) during the 1960s and '70s. The 1900 series was notable for being one of the few non-American competitors to the IBM System/360, enjoying significant success in the European and Commonwealth markets.

Creation of the ICT 1900 series

In early 1963 ICT was in negotiations to buy the computer business of Ferranti. In order to sweeten the deal Ferranti demonstrated to ICT the Ferranti-Packard 6000 (FP6000) machine, developed by its Canadian subsidiary Ferranti-Packard.

The FP6000 was an advanced design, notably including hardware support for multiprogramming. ICT considered using the FP6000 as their medium-sized processor in the 1965–1968 timeframe, replacing the ICT 1302. Another plan being considered was to license a new range of machines being developed by RCA, probably compatible with the expected IBM 8000.

Educational technology

Educational technology is the effective use of technological tools in learning. As a concept, it concerns an array of tools, such as media, machines and networking hardware, as well as considering underlying theoretical perspectives for their effective application.

Educational technology is not restricted to high technology. Also called e-learning, it includes an array of approaches, components, and delivery methods. For example, m-learning emphasizes mobility, but is otherwise indistinguishable in principle from educational technology.

Educational technology includes numerous types of media that deliver text, audio, images, animation, and streaming video, and includes technology applications and processes such as audio or video tape, satellite TV, CD-ROM, and computer-based learning, as well as local intranet/extranet and web-based learning. Information and communication systems, whether free-standing or based on either local networks or the Internet in networked learning, underlie many e-learning processes.
