123Topological group — Concepts in group theory category of groups subgroups, normal subgroups group homomorphisms, kernel, image, quotient direct product, direct sum semidirect product, wreath product …
124Cellular automaton — A cellular automaton (plural: cellular automata) is a discrete model studied in computability theory, mathematics, theoretical biology and microstructure modeling. It consists of a regular grid of cells , each in one of a finite number of states …
125Polyomino — The 18 one sided pentominoes, including 6 mirrored pairs …
126Nyquist frequency — Not to be confused with Nyquist rate. Frequencies above ƒs/2 (the Nyquist frequency) have an alias below ƒs/2, whose value is given by this graph. ƒs/2 is also called folding frequency, because of the symmetry between 0 and ƒs. The Nyquist… …
127Digital control — is a branch of control theory that uses digital computers to act as system controllers. Depending on the requirements, a digital control system can take the form of a microcontroller to an ASIC to a standard desktop computer. Since a digital… …
128Logovisual technology — The term logovisual technology was introduced c. 2000 (Blake, Varney 1999) as a generic description for methods that structure texts to aid thinking. It arose in relation to a particular history of research and development with applications in… …
