61Daubechies wavelet — Daubechies 20 2 d wavelet (Wavelet Fn X Scaling Fn) Named after Ingrid Daubechies, the Daubechies wavelets are a family of orthogonal wavelets defining a discrete wavelet transform and characterized by a maximal number of vanishing moments for… …
62Eigenvalue, eigenvector and eigenspace — In mathematics, given a linear transformation, an Audio|De eigenvector.ogg|eigenvector of that linear transformation is a nonzero vector which, when that transformation is applied to it, changes in length, but not direction. For each eigenvector… …
63Electronic density — In quantum mechanics, and in particular quantum chemistry, the electronic density is a probabilistic measure of the number of electrons occupying a given element of space. It is a scalar quantity depending upon three spatial variables and is… …
64Komar mass — Introduction and motivation = The Komar mass of a system is one of several formal concepts of mass that used in general relativity. The Komar mass can be defined in any stationary spacetime, which is a spacetime in which all the metric can be… …
65Solid harmonics — In physics and mathematics, the solid harmonics are solutions of the Laplace equation in spherical polar coordinates. There are two kinds: the regular solid harmonics R^m ell(mathbf{r}), which vanish at the origin and the irregular solid… …
66Partition function (mathematics) — The partition function or configuration integral, as used in probability theory, information science and dynamical systems, is an abstraction of the definition of a partition function in statistical mechanics. It is a special case of a… …
67Continuous-repayment mortgage — Analogous to continuous compounding, a continuous annuity[1][2] is an ordinary annuity in which the payment interval is narrowed indefinitely. A (theoretical) continuous repayment mortgage is a mortgage loan paid by means of a continuous annuity …
68Entity–attribute–value model — (EAV) is a data model to describe entities where the number of attributes (properties, parameters) that can be used to describe them is potentially vast, but the number that will actually apply to a given entity is relatively modest. In… …
69Fourier analysis — In mathematics, Fourier analysis is a subject area which grew out of the study of Fourier series. The subject began with trying to understand when it was possible to represent general functions by sums of simpler trigonometric functions. The… …
70Gamma correction — Gamma correction, gamma nonlinearity, gamma encoding, or often simply gamma, is the name of a nonlinear operation used to code and decode luminance or tristimulus values in video or still image systems. [cite book | title = Digital Video and HDTV …
