Recursion


Definition:

  • (n.) The act of recurring; return.

Example Sentences:

  • (1) The feasibility of estimating these parameters, demonstrated by the present study, suggests that a recursive least squares estimation procedure could be used to recover the time variation of each parameter during exercise stress testing of subjects with normal or nearly normal gas exchange.
  • (2) We have investigated the properties of a recursive process in which the output signal from a given RF excitation pulse may be used as the input (excitation) pulse of a subsequent iteration.
  • (3) A simple recursive formula, which yields an estimate for the statistical error resulting from pipetting errors accumulated throughout a dilution procedure, is described.
  • (4) A new three dimensional (3-D) recursive tracing algorithm was proposed.
  • (5) In the experimental analog, genetic selection or screening applied during recursive ensemble mutagenesis should force the evolution of an ensemble of mutants to a targeted cluster of related phenotypes.
  • (6) To account for the superior prognosis of hyperdiploid, B-progenitor acute lymphoblastic leukemia (ALL), we investigated the influence of trisomy in 1021 children greater than or equal to 1 year old by recursive partitioning analysis.
  • (7) The equilibrium equation for mixtures of two mutually competitive tight-binding ligands can be expressed in a recursive form, a form in which the dependent variable appears on both sides and the solution is found iteratively.
