Principal component analysis (PCA) is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of linearly uncorrelated variables called principal components. This transformation is defined in such a way that the first principal component has the largest possible variance, and each succeeding component in turn has the highest variance possible under the constraint that it is orthogonal to the preceding components. The resulting vectors are an uncorrelated orthogonal basis set. PCA is sensitive to the relative scaling of the original variables.
Beatboxing is a form of vocal percussion primarily involving the art of mimicking drum machines, using one's mouth, lips, tongue, and voice. It may also involve vocal imitation of turntablism, and other musical instruments. Beatboxing today is connected with hip-hop culture, often referred to as "the fifth element" of hip-hop, although it is not limited to hip-hop music. The term "beatboxing" is sometimes used to refer to vocal percussion in general.

The areas of Sheffield, a city and metropolitan borough in the north of England, vary widely in size and history. Some of the areas developed from villages or hamlets, that were absorbed into Sheffield as the city grew, and thus their centres are well defined, but the boundaries of many areas are ambiguous. The areas of Sheffield do not play a significant administrative role, but the city is divided into 28 electoral wards for local elections and 6 parliamentary constituencies for national elections.
Mosborough ward — which includes the districts of Halfway, Mosborough village, Waterthorpe, Westfield, as well as the rural area of Plumbley— is one of the 28 electoral wards in City of Sheffield, England.

In signal processing, the high frequency content measure is a simple measure, taken across a signal spectrum, that can be used to characterize the amount of high-frequency content in the signal. The magnitudes of the spectral bins are added together, but multiplying each magnitude by the bin "position". Thus if X(k) is a discrete spectrum with N unique points, its high frequency content measure is:
Crackout were an English three-piece pop punk band, formed in Bicester, Oxfordshire in 1997.
Grrr! It's Betty Boo is the second album by Betty Boo, released on 12 October 1992 via WEA Records.

Further singles from the album were "I'm On My Way" Catch Me, Thing Goin On and "Hangover". The record is dedicated to her father. The cover art is based on the iconic package of Tigra cigarettes.

The first lifeboat was stationed in the town in 1901 but since 1976 two inshore lifeboats (ILBs) have been operated, a B Class rigid-hulled boat and an inflatable D Class.
In information theory, dual total correlation, excess entropy, or binding information is one of the two known non-negative generalizations of mutual information. While total correlation is bounded by the sum entropies of the n elements, the dual total correlation is bounded by the joint-entropy of the n elements. Although well behaved, dual total correlation has received much less attention than the total correlation. A measure known as "TSE-complexity" defines a continuum between the total correlation and dual total correlation.
xeno-canto is a citizen science project and repository in which volunteers record, upload and annotate recordings of birdsong and bird calls. Since it began in 2005, it has collected over 400,000 sound recordings from more than 10,000 species worldwide, and has become one of the biggest collections of bird sounds in the world. All the recordings are published under one of the Creative Commons licenses, including some with open licences.
