at the Haneda Airport‚Japan. After that we stayed at Hotel Metropolitan Tokyo. The third day‚ we’ll go to the Japan’s communications and observation tower‚Tokyo Tower. The tower acts as a support structure for an antenna. Originally intended for television broadcasting‚ radio antennas were installed in 1961‚ but the tower is now used to broadcast signals for Japanese media outlets. The next day‚ we go to the Kaminari Gate in Asakusa‚ Tokyo. The Kaminari Gate was first built in 941 by Taira no Kinmasa

addition‚ poor read rates are sometimes a problem when the tag is rotated into an orientation that does not align well with the reader. These issues are usually minimized by proper implementation of multiple readers and use of tags with multiple axis antennas. Because RFID is not a line-of-sight technology like barcoding‚ new security issues could develop. For

Sexual selection: it is part of natural selection. Sexual selection acts on an organism’s ability to obtain or successfully couple with a mate. Selection makes many organisms go to extreme lengths in order to find a mate such as: peacocks need to develop a beautiful tail‚ elephant seals fight over territories…. Sexual selection is often powerful enough to produce features that are harmful to the individual’s survival. For example‚ extravagant and colorful tail feathers or fins are likely to attract

signal is used for two reasons: • To reduce the wavelength for efficient transmission and reception (the optimum antenna size is ½ or ¼ of a wavelength). A typical audio frequency of 3000 Hz will have a wavelength of 100 km and would need an effective antenna length of 25 km! By comparison‚ a typical carrier for FM is 100 MHz‚ with a wavelength of 3 m‚ and could use an antenna only 80 cm long. • To allow simultaneous use of the same channel‚ called multiplexing. Each unique signal can be

object detection system which uses radio waves to determine the range ‚ altitude ‚ direction ‚ or speed of objects. The radar dish or antenna Transmits pulses of radio waves or microwaves which bounces off any object in their path.The object returns a tiny part of the wave’s energy to a dish or antenna which is usually located at the same site as the transmitter. But sound waves have certain distinct advantages over light waves :Sound

In scientific terms‚ radio is part of the electromagnetic spectrum. Electromagnetic waves push into space going the speed of light‚ which is 300‚000 kilometers per second. When equipment is attached to an antenna‚ the energy becomes radio waves. Some of the energy can be received by another antenna‚ and using a radio receiver‚ the energy connects the transmitter and receiver. Information that is added to the radio waves can be sent as messages known as television programs‚ walkie talkies‚ and other

strip onto the back of a hinged clothespin. Bend a pipe cleaner in a V-shape for antenna‚ then glue it and googly eyes to a craft pom-pom. Glue that pom-pom to the front of the clothespin (where it opens). Attach several other brightly colored pom-poms along the rest of the clothespin for the body. Simplify: Have the clothespin and magnet already attached to each other and have the little kids glue the pompoms and antenna. Extend: Have the children recap the story with their little caterpillar
