They estimated the gaps using Raff's method, logit method, lag method, Ashworth Method, and Maximum likelihood Method.
The azimuthal normal angles estimated by the MVA are close those from the time lag method.
The effective diffusion coefficients were measured using the time-lag method.
Theoretical model for single fiber push-out testing is obtained by shear-lag method.
Small lags lead to strongly biased estimates for the fixed-lag method, and unbiased estimates are at the cost of a large variance.
We compare the estimation of the EM intermediate quantity with the one obtained by the fixed lag method of [27], for different values of the lag (namely, 1,2,5,10,50).
Takeuchi et al. (2002) compared different methods for calculating a shock normal and showed that a time lag method gives the most reasonable solution.
Time lag method is a widely used technique in constant volume systems for the determination of the diffusion and permeability coefficients of gasses in membrane.
The proposed method can be applied for any value of the ratio of drift velocities, while the time-lag method is appropriate only as the ratio approaches infinity.
As a direct result, the ratio of drift velocities increases with increasing temperature and makes the time-lag method appropriate at elevated temperatures.
Permeability of He, O2, N2 and CO2 has been measured in a temperature range from 25to85°C°C using the variable-pressure technique with the time-lag method.
