Body roundess index (BRI) is a calculated geometric index used to quantify a person's individual body shape. Based on the principle of body eccentricity , it provides a rapid visual and anthropometric tool for health evaluation.
Miller indices form a notation system in crystallography for lattice planes in crystal (Bravais) lattices. In particular, a family of lattice planes of a given (direct) Bravais lattice is determined by three integers h, k, and ℓ, the Miller indices. They are written (hkℓ), and denote the family of (parallel) lattice planes (of the given ...
A price index aggregates various combinations of base period prices ( ), later period prices ( ), base period quantities ( ), and later period quantities ( ). Price index numbers are usually defined either in terms of (actual or hypothetical) expenditures (expenditure = price * quantity) or as different weighted averages of price relatives ...
In fact, this stock index of America’s top companies has returned an average of about 10 percent annually over time. That blows the returns of bonds out of the water and outperforms CDs, too.
Einstein notation. In mathematics, especially the usage of linear algebra in mathematical physics and differential geometry, Einstein notation (also known as the Einstein summation convention or Einstein summation notation) is a notational convention that implies summation over a set of indexed terms in a formula, thus achieving brevity.
Whipple's index (or index of concentration), invented by American demographer George Chandler Whipple (1866–1924), is a method to measure the tendency for individuals to inaccurately report their actual age or date of birth. Respondents to a census or other survey sometimes report their age or date of birth as a round number (typically ending ...
and lowered by: and for a mixed tensor: We need not raise or lower all indices at once: it is perfectly fine to raise or lower a single index. Lowering an index of an tensor gives a tensor, while raising an index gives a (where have suitable values, for example we cannot lower the index of a tensor.)
In astronomy, the color index is a simple numerical expression that determines the color of an object, which in the case of a star gives its temperature. The lower the color index, the more blue (or hotter) the object is. Conversely, the larger the color index, the more red (or cooler) the object is. This is a consequence of the logarithmic ...
