Extrapolation methods can provide a very good estimate of one matrix- vector product, but the problem is that we do not know the best value of v a priori.
Both methods have measurement error, with the majority of the measurement error in the heart rate extrapolation method coming from the estimate of maximal heart rate (ie, 220-age).
An error analysis showed that the overall uncertainty in the estimation of the thermal contact conductance by extrapolation method is considered to be 15.
Corrosion rates of the investigated materials were calculated using the Tafel extrapolation method.
We applied a polynomial vector extrapolation method, namely reduced rank extrapolation (RRE), to the iterative method proposed by Lin [24] which computes the minimal positive solution of NARE as the minimal positive solution of a vector equation.
The stability and integrity of the coating of the different traps is the most important condition for validity of the size extrapolation method for the neutron lifetime measurement.
The direction of change was always correctly indicated for the current-dollar estimates, and it was correctly indicated at least 90 percent of the time for the real estimates using either the single-deflation method or the extrapolation method.
Therefore, we applied an extrapolation method to determine the contact line position.
Contract notice: Biogenic solid fuels in industry, trade, services sector (ghd) - development and validation of an extrapolation method for the determination of fuel use for the years 2005 to 2020.
If the original sequence is divergent, the sequence transformation acts as an extrapolation method to the anti-limit s.
Besides, calculation of the [gamma]-values required for the energy extrapolation method depends on the UCN spectra.
A linear extrapolation method was chosen as an operational definition of the glass transition temperature for this study.
For water transportation, an extrapolation method using persons engaged in production replaced the double-deflation method; an evaluation based on newly available data from the 1987 Census of Transportation showed that the quantity measures used to estimate the previously used gross output series were not representative of all activities of the industry.
Important questions that are dealt with concern the requirements of the data taken and the type of extrapolation method used for the lifetime assessment.
The extrapolation method will yield the correct results only if the rates of change in constant-dollar gross output and inputs are the same.
