In statistics, a power transform is a family of functions applied to create a monotonic transformation of data using power functions.It is a data transformation technique used to stabilize variance, make the data more normal distribution-like, improve the validity of measures of association (such as the Pearson correlation between variables), and for other data stabilization procedures.
Low power, low bit rate, and intended use distinguish this type of network from a wireless WAN that is designed to connect users or businesses, and carry more data, using more power. The LPWAN data rate ranges from 0.3 kbit/s to 50 kbit/s per channel.
In critical theory, power-knowledge is a term introduced by the French philosopher Michel Foucault (French: le savoir-pouvoir). According to Foucault's understanding, power is based on knowledge and makes use of knowledge; on the other hand, power reproduces knowledge by shaping it in accordance with its anonymous intentions.

Power line adapter. Power-line communication (PLC) is the carrying of data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. The line that does so is known as a power-line carrier. In the past, power lines were solely used for transmitting electricity. However, with ...
The Schoellkopf Power Station was built on land owned by Jacob F. Schoellkopf above the Niagara Gorge near the American Falls, 1,600 feet (490 m) downriver from Rainbow Bridge. Understanding the growing need for electricity and the role of harnessing the Falls, Schoellkopf purchased the land for the hydraulic canal on May 1, 1877 for $71,000.
"Power Play" is the 115th episode of the American science fiction television series Star Trek: The Next Generation. It is the 15th episode of the fifth season . Set in the 24th century, the series follows the adventures of the Starfleet crew of the Federation starship Enterprise -D .
Power usage effectiveness (PUE) or power unit efficiency is a ratio that describes how efficiently a computer data center uses energy; specifically, how much energy is used by the computing equipment (in contrast to cooling and other overhead that supports the equipment).
For example, Bluetooth provides a much shorter propagation range between 1 and 100 metres (1 and 100 yards) [111] and so in general has a lower power consumption. Other low-power technologies such as Zigbee have fairly long range, but much lower data rate. The high power consumption of Wi-Fi makes battery life in some mobile devices a concern.
