nonlinear field theory
31Born-Infeld theory — In physics, the Born Infeld theory is a nonlinear generalization of electromagnetism (see nonlinear electrodynamics). We will use the relativistic notation here as this theory is fully relativistic.The Lagrangian density is:mathcal{L}= b^2sqrt{… …
32Coding theory — is the study of the properties of codes and their fitness for a specific application. Codes are used for data compression, cryptography, error correction and more recently also for network coding. Codes are studied by various scientific… …
33Multiple-prism dispersion theory — The first description of multiple prism arrays, and multiple prism dispersion, was given by Newton in his book Opticks.[1] Prism pair expanders were introduced by Brewster in 1813.[2] A modern mathematical description of the single prism… …
34automata theory — Body of physical and logical principles underlying the operation of any electromechanical device (an automaton) that converts information input in one form into another, or into some action, according to an algorithm. Norbert Wiener and Alan M.… …
35Item response theory — In psychometrics, item response theory (IRT) is a body of theory describing the application of mathematical models to data from questionnaires and tests as a basis for measuring abilities, attitudes, or other variables. It is used for statistical …
36Info-gap decision theory — is a non probabilistic decision theory that seeks to optimize robustness to failure – or opportuneness for windfall – under severe uncertainty,[1][2] in particular applying sensitivity analysis of the stability radius type[3] to perturbations in… …
37Orbit (control theory) — The notion of orbit of a control system used in mathematical control theory is a particular case of the notion of orbit in group theory. Contents 1 Definition 2 Orbit theorem (Nagano Sussmann) 3 Corollary (Rashevsky Chow theorem) …
38Braid theory — The braid is associated with a planar graph. The 24 elements of a permutatio …
39Failure theory (material) — v · d · e Materials failure modes Buckling · Corro …
40Spectral phase interferometry for direct electric-field reconstruction — In ultrafast optics, spectral phase interferometry for direct electric field reconstruction (SPIDER) is an ultrashort pulse measurement technique.The basicsSPIDER is an interferometric ultrashort pulse measurement technique in the frequency… …
