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.
