Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc

The pulsed electro acoustic analysis (PEA) can be used for space charge measurements under dc or ac fields. The PEA method is a non-destructive technique for profiling space charge accumulation in polymeric materials. The method was first proposed by T.Takada et al. in 1985. The pulsed electro acoustic (PEA) method has been used for various applications. PEA systems can measure space charge profiles in the thickness direction of specimen, with a resolution of around 10 microns, and a repetition rate in the order of milliseconds. The experimenta ....etc

This paper addresses the role of power from space for use on earth in the next century. It synopsizes the problems associated with our present practices of supplying power for the world in the face of a projected increase in demand and notes the need to reduce the use of fossil fuels. The probable shortfall by the middle of the next century is estimated and options for earth-based and space-based sources of energy are examined. The paper concludes that energy obtained from space by solar power satellite is a viable and necessary way of meeting ....etc

Introduction
 The Sun is a giant fusion reactor , located some 150 million km from the Earth, radiating 2.3 billion times more energy than what strikes the disk of the Earth which itself is more energy in an hour , than all human civilization directly uses in a year, and it will continue to produce free energy for billions of years.
 A single kilometerwide band of geosynchronous earth orbit experiences enough solar flux in one year (approximately 212 terawattyears) to nearly equal the amount of ene ....etc

Abstruct-
Analysis, design, and implementation of the space vector modulated three-phase to three-phase matrix converter with input power factor correction are presented. The majority of published research results on the matrix converter control is given an overview, and the one, which employs sheous output-voltage and input-current space vector modulation, is systematically reviewed. The modulation algorithm is theoretically derived from the desired average transfer functions, using the indirect transfer function approach. ....etc
