current headlines regarding “extreme weather events” occurring around the world and here in America left a curiosity about the history and technology used to forecast the Earth’s weather. Around the world meteorologists use technology such as satellites‚ infrared‚ radio‚ and radar transmissions‚ to help determine the most accurate forecast possible. However‚ even with the most advanced technology available‚ no predication is 100% accurate. Captain Robert Fitzroy of Great Britain started a forecasting

Wireless Power Transmission for Solar Power Satellite (SPS) (Second Draft by N. Shinohara) 1. Theoretical Background It is known that electromagnetic energy also associated with the propagation of the electromagnetic waves. We can use theoretically all electromagnetic waves for a wireless power transmission (WPT). The difference between the WPT and communication systems is only efficiency. The Maxwell’s Equations indicate that the electromagnetic field and its power diffuse to all directions. Although

The Laffer curve‚ named after the economist Arthur Laffer‚ is a curve that demonstrates the trade-off between tax-rates and tax-revenues (Wanniski 1978). It is used to illustrate the concept of taxable income elasticity‚ the idea that a government can maximise the revenue by setting the tax rates at an optimum point. This curve can be traced back as far as 1844 to a French economist Jules Dupit who in 1844 found similar effects as Laffer did (Laffer 2004). Dupit also saw tax revenues rising from

Whatever the mission‚ be it manned or unmanned‚ for scientific research‚ applications or space transportation‚ a spacecraft must withstand the extreme stresses which occur during the launch phase‚ and once in orbit‚ the rigours of the space environment. There is one way of making sure of this: to test the spacecraft on Earth under conditions simulating‚ as closely as possible‚ those it will meet during the launch and its orbital life. This can be done with with tests which demonstrate by application

equatorial plane of the earth such that a satellite appears to hover over a fixed point on the equator. The period of revolution is equal to the period of rotation of the earth with respect to the stars‚ or 23 hours 56 minutes 4.1 seconds‚ and thus by Kepler’s third law the orbital radius is 42‚164 km. Taking into account the radius of the earth‚ the height of a satellite above the equator is 35‚786 km. Clarke observed that only three satellites would be required to provide communications

The Future of Satellite Internet: For many people throughout the world‚ the only way to get online is by using satellite internet service. This is because they live in regions where traditional cable or DSL lines are not there. This may be because of landscape or the fact that some homes and businesses are simply located too far into rural regions and it is not cost effect for traditional companies to run lines to only one or two clients. However‚ a satellite internet connection does not rely
