Approximation theory — In mathematics, approximation theory is concerned with how functions can best be approximated with simpler functions, and with quantitatively characterizing the errors introduced thereby. Note that what is meant by best and simpler will depend on … Wikipedia
Scaling pattern of occupancy — William E. Kunin (1998) [Kunin, WE. 1998. Extrapolating species abundance across spatial scales. Science, 281: 1513 1515.] presented a method to estimate species relative abundance by using the presence absence distribution map. In his paper, he… … Wikipedia
Successive approximation ADC — Successive Approximation redirects here. For behaviorist B.F. Skinner s method of guiding learned behavior, see Shaping (psychology). A successive approximation ADC is a type of analog to digital converter that converts a continuous analog… … Wikipedia
Successive Approximation ADC — A successive approximation ADC is a type of analog to digital converter that converts a continuous analog waveform into a discrete digital representation via a binary search through all possible quantization levels before finally converging upon… … Wikipedia
Stationary phase approximation — In mathematics, the stationary phase approximation is a basic principle of asymptotic analysis, applying to oscillatory integrals taken over n dimensional space Rn where i is the imaginary unit. Here f and g are real valued smooth functions. The… … Wikipedia
Dirac delta function — Schematic representation of the Dirac delta function by a line surmounted by an arrow. The height of the arrow is usually used to specify the value of any multiplicative constant, which will give the area under the function. The other convention… … Wikipedia
Singular value decomposition — Visualization of the SVD of a 2 dimensional, real shearing matrix M. First, we see the unit disc in blue together with the two canonical unit vectors. We then see the action of M, which distorts the disk to an ellipse. The SVD decomposes M into… … Wikipedia
Ab initio quantum chemistry methods — are computational chemistry methods based on quantum chemistry.[1] The term ab initio was first used in quantum chemistry by Robert Parr and coworkers, including David Craig in a semiempirical study on the excited states of benzene.[2][3] The… … Wikipedia
Daubechies 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… … Wikipedia
Orthogonal wavelet — An orthogonal wavelet is a wavelet where the associated wavelet transform is orthogonal. That is the inverse wavelet transform is the adjoint of the wavelet transform. If this condition is weakened you may end up with biorthogonal wavelets.… … Wikipedia
Newton's theorem of revolving orbits — Figure 1: An attractive force F(r) causes the blue planet to move on the cyan circle. The green planet moves three times faster and thus requires a stronger centripetal force, which is supplied by adding an attractive inverse cube force. The … Wikipedia
