New technologies in 5G

5G is bringing a wide range of technology inventions in both the 5G NR (New Radio) air interface design as well as the 5G NextGen core network.

The new 5G NR air interface introduces many foundational wireless inventions, and in our opinion, the top five are:

Scalable OFDM numerology with 2n scaling of subcarrier spacing
Flexible, dynamic, self-contained TDD subframe design
Advanced, flexible LDPC channel coding
Advanced massive MIMO antenna technologies
Advanced spectrum sharing techniques

How Energy conversion from coal is done?

Single generator sets of over 600 MW are now used in the UK, though there are many smaller generators in use. A 600 MW generator can supplythe average needs of over 1 million UK households. Three or four such generators are typically installed in a single large coal-fired station which isoften sited close to a coal mine, away from the city dwellers who consume the electricity. Such generators are usually driven by a compound arrangement of highpressure, intermediate-pressure and low-pressure turbines, increasing in size as the pressure decreases. Modern turbines rotate in a speed range from 1500 to 3500 r.p.m., usually 3000 r.p.m. for the UK’s 50 Hz system. For large coal-fired plant the steam pressure could be 25 megapascals (MPa) with steam temperatures of 500–600 °C to improve the thermodynamic efficiency. In nuclear reactors, which operate under less demanding conditions, the steam is superheated to about 5 MPa and 300 °C. Modern water tube boilers are complex and have ...

5 TOP FACTS LIGHTHOUSES

1 The builder of the Lighthouse of Alexandria, Sostratus – disobeying orders from the pharaoh Ptolemy – engraved his name and a dedication to the sea gods on the tower base. Fame 2 The technical term for the study of lighthouses is ‘pharology’, a word derived from Pharos, the island upon which the great Lighthouse of Alexandria once stood. Academia 3 George Meade built many notable lighthouses in the US during the classical lighthouse period. He is remembered in history as the winning general in the Battle of Gettysburg. War 4 The tallest lighthouse in the world is the Yokohama Marine Tower in Yokohama, Japan. The structure ﬂ ashes alternately green and red every 20 seconds. Tallest 5 Originally lighthouses were lit merely with open ﬁ res, only later progressing through candles, lanterns and electric lights. Lanterns tended to use whale oil as fuel.
