Especially, SRA interpolates a given function with a specific rational function whose poles and zeros are simple, which means that there is no multiplicity in poles and zeros.… … Wikipedia**Diophantine approximation**— In number theory, the field of Diophantine approximation, named after Diophantus of Alexandria, deals with the approximation of real numbers by rational numbers. The absolute value of the difference between the real number to be approximated and… … Wikipedia**Orders of approximation**— In science, engineering, and other quantitative disciplines, orders of approximation refer to formal or informal terms for how precise an approximation is, and to indicate progressively more refined approximations: in increasing order of… … Wikipedia**Boussinesq approximation (water waves)**— In fluid dynamics, the Boussinesq approximation for water waves is an approximation valid for weakly non linear and fairly long waves. The approximation is named after Joseph Boussinesq, who first derived them in response to the observation by… … Wikipedia**Oseen's Approximation**— In 1910 Carl Wilhelm Oseen proposed Oseen s Approximation to treat problems in which a flow field consists of small disturbance of a constant mean flow. His work was based on the experiments of Navier Stokes. Stokes studied a sphere of radius “a” … Wikipedia
