The basic function of a variable speed drive (VSD) is to control the flow of energy from the mains to the process.
That method is how old, fixed-speed air conditioners work. They are either on or off, which causes them to cycle on and off quite frequently, wasting energy. Variable-speed air conditionerswork more like the gas pedal in your car, letting the AC adjust to the needs of your home. This ...
A fascinating thing about Earth, which may make it unique, is that all through its very long existence, all four and a half billion years, variations in the luminosity of the Sun have been compensated for by a variable greenhouse effect. It's like a sort of geophysical thermostat keeping t...
A threat intelligence platform and DGA dataset are used for detecting known DGA domain names. Entropy-based In computing, entropy is a measure of the uncertainty associated with a random variable. It is a measure of how random a piece of information is. Typically, DGA domain names generated ba...
A variable cost is an expense that changes in proportion to production output or sales. When production or sales increase, variable costs increase; when production or sales decrease, variable costs decrease. Variable costs stand in contrast to fixed costs, which do not change in proportion to pro...
Some elements differ in their capacity to combine with other elements depending on the nature of the reaction; this property is called variable valency. For example, the iron in ferrous oxide exhibits a valency of +2, whereas in ferric oxide, it has a valency of +3. ...
Continuously variable automatic transmissions, or CVTs, shift among ratios but not gears, a trait that allows them to make the most of an engine's power band.
A variable area flow meter(Figure 1) is a type of differential pressure (d/p) flow meter. Variable area flow meters are simple and versatile devices that operate at a relatively constant pressure drop and provide flow measurement of liquids, gases, and steam....
