Stream cipher. The operation of the keystream generator in A5/1, an LFSR-based stream cipher used to encrypt mobile phone conversations. A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream ( keystream ). In a stream cipher, each plaintext digit is encrypted one at a time with the ...
World War 3 is a modern military first-person shooter set in the global conflict of a catastrophic future. [3] [10]Described as "a more hardcore Battlefield" in 2018, in June 2020 the developer The Farm 51 planned a revamp and relaunch together with the publisher My.Games and co-publisher The 4 Winds Entertainment joined in 2021; [2] in 2021 the game seemed to be moving away from the "hardcore ...
Arthur Lyon & Co Ltd. was a company based in London, England founded by Arthur Anderson Lyon M.I.Mech.E. (1876–1962). Arthur Anderson Lyon was an engineer and inventor who appears in the patent records in 1911 with a portable signalling device, [1] but by mid-1916 his inventions move from signalling lamps to electric generators and batteries.
One-time pad. A format of one-time pad used by the U.S. National Security Agency, code named DIANA. The table on the right is an aid for converting between plaintext and ciphertext using the characters at left as the key. In cryptography, the one-time pad ( OTP) is an encryption technique that cannot be cracked, but requires the use of a single ...
Nuclear marine propulsion is propulsion of a ship or submarine with heat provided by a nuclear reactor. The power plant heats water to produce steam for a turbine used to turn the ship's propeller through a gearbox or through an electric generator and motor. Nuclear propulsion is used primarily within naval warships such as nuclear submarines ...

Heat recovery steam generator. A heat recovery steam generator ( HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration) or used to drive a steam turbine ( combined cycle ).
1884 (140 years ago)(1884) A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. [1] [2] Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into ...
