- Classical control [r]: Methodologies developed prior to the advent of state space methods, which rely heavily on complex analysis and transform methods, especially the Laplace and Fourier transforms, as well as graphical techniques.
^{[e]} - Convolution (mathematics) [r]: A process which combines two functions on a set to produce another function on the set: the value of the product function depends on a range of values of the argument.
^{[e]} - Distributed computing [r]: A strategy for improving the speed of highly parallelizable tasks by distributing pieces of the problem across many computers that together form a distributed computing system, e.g. BOINC, SETI@home.
^{[e]} - Distribution (mathematics) [r]: Objects which generalize functions, used to formulate generalized solutions of partial differential equations.
^{[e]} - Electromagnetic wave [r]: A change, periodic in space and time, of an electric field
**E**(**r**,t) and a magnetic field**B**(**r**,t); a stream of electromagnetic waves, referred to as electromagnetic radiation, can be seen as a stream of massless elementary particles, named photons.^{[e]} - Fixed point [r]: A point in the domain of a function that is mapped to itself by the function, i.e., a point
*x*such that*f*(*x*) =*x*.^{[e]} - Helmholtz decomposition [r]: Decomposition of a vector field in a transverse (divergence-free) and a longitudinal (curl-free) component.
^{[e]} - Inhomogeneous Helmholtz equation [r]: An elliptic partial differential equation arising in acoustics and electromagnetism.
^{[e]} - Joseph Fourier [r]: was a French mathematician and physicist credited with describing the Fourier series based on which the Fourier transform has been formed.
^{[e]} - NMR spectroscopy [r]: The use of
**electromagnetic radiation**, in the presence of a**magnetic field**, to obtain information regarding**transitions between different nuclear spin states**of the nuclei present in the sample of interest.^{[e]} - Normal distribution [r]: a symmetrical bell-shaped probability distribution representing the frequency of random variations of a quantity from its mean.
