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

THERMAL POWER STATION

The basic energy cycle involved in the plant is as follows :

Chemical Energy ---> Mechanical Energy ---> Electrical Energy

Turbine
Turbine converts the heat energy of the steam into mechanical energy.

The super heated steam works on the blades of the turbine and hence the blades starts rotating to produce the mechanical energy.
1) High pressure turbine.
2) Intermediate Pressure turbine.
3) Low pressure turbine.

Abstract— Computational Private Information Retrieval (cPIR) protocols allow a client to retrieve one bit from a database, without the server inferring any information about the queried bit. These protocols are too costly in practice because they invoke complex arithmetic operations for every bit of the database. In this paper, we present pCloud, a distributed system that constitutes the first attempt toward practical cPIR. Our approach assumes a disk-based architecture that retrieves one page with a single query. Using a striping technique, ....etc

THE INTERNATIONAL SPACE STATION (ISS)
In 1984, President Ronald Reagan proposed that the United States, in cooperation with other countries, build a permanently inhabited space station. Reagan envisioned a station that would have government and industry support. The U.S. forged a cooperative effort with 14 other countries (Canada, Japan, Brazil, and the European Space Agency -- United Kingdom, France, Germany, Belgium, Italy, The Netherlands, Denmark, Norway, Spain, Switzerland, Sweden). During the planning of the ISS and after the fall of th ....etc
