  • 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. [e]
