To whom it may concern at the Woods Hole Oceanographic Institute: As we were able to learn more about the REMUS SharkCam‚ I would like to compliment the hard work of the scientists to acquire the data on sharks. Many people usually depict sharks as dangerous marine animals but with the footage it was seen that they are only living their lives responding with what their natural instinct tells them as any other animal‚ including us. It was amazing to learn the sixth and seventh sense sharks have and

refers to a change in the fundamental nature of the service‚ non-backwards-compatible transmission technology‚ higher peak bitrates‚ new frequency bands‚ wider channel frequency bandwidth in Hertz‚ and higher capacity for many simultaneous data transfers (higher system spectral efficiency in bit/second/Hertz/site). New mobile generations have appeared about every ten years since the first move from 1981 analog (1G) to digital (2G) transmission in 1992. This was followed‚ in 2001‚ by 3G multi-media

Microwaves History of Discovery: In 1864 James Clerk Maxwell predicted the existence of electromagnetic waves/microwaves. Then in 1888 Heinrich Hertz was the first to demonstrate the existence of microwaves by building an apparatus that detected and produced microwaves in the UHF region. Also in 1894 J. C. Bose publicly demonstrated radio control of a bell using millimeter wavelengths‚ and conducted research into the propagation of microwaves. Origin(s): One origin of microwaves include a maser

The frequency of an alternating sine wave is the amount of cycles per second. Frequency is measured in hertz. One hertz is equivalent to one cycle per second. The frequency coming out of your electrical plug at home is 60 Hz. The peak value in

Theory required a period of over three decades to develop‚ while the Special Theory of Relativity was created in a single year. The development of the Quantum Theory began in 1887 when a German physicist‚ Heinrich Hertz‚ was testing Maxwell’s Theory of Electromagnetic Waves. Hertz discovered that ultraviolet light discharged certain electrically charged metallic plates‚ a phenomenon that could not be explained by Maxwell’s Wave Theory. In order to explain this phenomenon termed the photoelectric

These electrons (called ‘photoelectrons’) were only emitted when the frequency of the ultra-violet light was above a certain value (called the ‘threshold frequency’)

Dallas‚ TX. Market Research The global car industry is undergoing a radical transformation (Perot Systems‚ 2010). In the past‚ virtually all of the major US car rental companies were owned and operated by automobile manufacturers‚ Currently‚ Hertz (80% owned by Ford) remains in auto manufacturer control (Perot Systems‚ 2010). Entrepreneurs now own the other car rental companies; these new owners have brought additional standards to the management of leading car rental companies. Perot Systems
