Stochastic resonance — (also known as SR) is observed when noise added to a system improves the systems performance in some fashion. More technically, SR occurs if the signal to noise ratio of a nonlinear system or device increases for moderate values of noise… … Wikipedia
Spectrum continuation analysis — (SCA) is a generalization of the concept of Fourier series to non periodic functions of which only a fragment has been sampled in the time domain.Recall that a Fourier series is only suitable to the analysis of periodic (or finite domain)… … Wikipedia
Stochastic electrodynamics — In theoretical physics, Stochastic electrodynamics (SED) refers to a theory which posits that the interaction of elementary particles with the vacuum radiation field, or zero point field, is ultimately responsible for various familiar quantum… … Wikipedia
Frequency spectrum — Familiar concepts associated with a frequency are colors, musical notes, radio/TV channels, and even the regular rotation of the earth. A source of light can have many colors mixed together and in different amounts (intensities). A rainbow, or… … Wikipedia
Cross-spectrum — In time series analysis, the cross spectrum is used as part of a frequency domain analysis of the cross correlation or cross covariance between two time series. Contents 1 Definition 2 Squared coherency spectrum 3 See also … Wikipedia

Perron–Frobenius theorem — In linear algebra, the Perron–Frobenius theorem, proved by Oskar Perron (1907) and Georg Frobenius (1912), asserts that a real square matrix with positive entries has a unique largest real eigenvalue and that the corresponding… … Wikipedia

Military simulation — Participants from five nations (Singapore, United Kingdom, Malaysia, Australia and New Zealand) conduct a map exercise during Exercise SUMAN Warrior 2006 Military simulations, also known informally as war games, are simulations in which theories… … Wikipedia
Spectral density — In statistical signal processing and physics, the spectral density, power spectral density (PSD), or energy spectral density (ESD), is a positive real function of a frequency variable associated with a stationary stochastic process, or a… … Wikipedia
Superlens — A superlens, super lens or perfect lens is a lens which uses metamaterials to go beyond the diffraction limit. The diffraction limit is an inherent limitation in conventional optical devices or lenses.[1] In 2000, a type of lens was proposed,… … Wikipedia
