21Power graph analysis — In computational biology, power graph analysis is a method for the analysis andrepresentation of complex networks. Power graph analysis is the computation, analysis and visual representation of a power graph from a graphs (networks).Power graph… …
22Power quality — In its broadest sense, power quality is a set of boundaries that allows electrical systems to function in their intended manner without significant loss of performance or life. The term is used to describe electric power that drives an electrical …
23Power of a point — Figure 1. Illustration of the power of point P in the circle centered on the point O. The distance s is shown in orange, the radius r is shown in blue, and the tangent line segment PT is shown in red. In elementary plane geometry, the power of a… …
24Power attenuator (guitar) — In electric rock guitar, attenuators are used to dissipate some or all of the amplifier s power in the attenuator s built in, mostly resistive dummy load instead of letting that power drive the speaker, in order to silence or reduce the output… …
25Power kite — A power kite or traction kite is a large kite designed to provide significant pull to the user. They come in three main forms: foils, leading edge inflatables and Supporting Leading Edge. There are also rigid framed kites and soft single skin… …
26Power transform — In statistics, the power transform is a family of transformations that map data from one space to another using power functions. This is a useful data (pre)processing technique used to reduce data variation, make the data more normal distribution …
27Power associativity — In abstract algebra, power associativity is a weak form of associativity.An algebra (or more generally a magma) is said to be power associative if the subalgebra generated by any element is associative.Concretely, this means that if an element x… …
28Power-law fluid — NOTOC A Power law fluid is a type of generalized Newtonian fluid for which the shear stress, tau; , is given by : au = K left( frac {partial u} {partial y} ight)^n where: * K is the flow consistency index (SI units Pa bull;s n ), * part; u /… …
29power series — Math. an infinite series in which the terms are coefficients times successive powers of a given variable, or times products of powers of two or more variables. [1890 95] * * * ▪ mathematics in mathematics, an infinite series that can be… …
30power factor — noun The ratio of the actual power to the apparent power in an alternating current power system; specifically, the cosine of the phase angle between the voltage and the current. The power factor is of interest because it is a measure of the power …
