The results for one group of these specimens were analyzed using the cross-correlation technique presented in this study.
The images are compared to determine particle displacement using a cross-correlation algorithm, yielding the velocity field [40].
Therefore, considering the acquisition ambiguity problems and the shortage of the existing methods, a NCCFR (New Cross-Correlation Function Reconstruction) acquisition algorithm is proposed.
The correlation (or cross-correlation) coefficient [r.sub.xy] is a dimensionless number between -1 and +1.
Therefore, the objectives of this paper are: to develop a framework for handling uncertainties in the process model; to investigate the use of the cross-correlation function and recursive least squares to obtain parameter estimates, which are then refined using nonlinear optimization, such as the Levenberg-Marquardt method; and to test the proposed results using a simulated hot steel rolling mill process.
This technique of analysis consists of determining the cross-correlation function between the blades.
By default, cross-correlation function (CCF) calculates Pearson's correlation coefficient (r) for determined lags; however, features of the interested data necessitated analyzing with nonparametric method.
Both Figures 3 and 4 clearly show that the cross-correlation values are very small, which enables the GPS satellites to broadcast signals simultaneously at the same frequency using different C/A codes.
Table 1 shows the averaged (across time) peak cross-correlation coefficients for each subject and wavelet band.
Through the application of some statistical analysis methods, we try to identify and quantify the level of the correlation of some acoustic and voice parameters and the impact of this cross-correlation on the optimization of the communication structures.
The calculated values for all data channels were averaged to obtain an overall value ([+ or -]S.D.) for each method (cross-correlation values, CORA and BioRank).
[[THETA].sub.N](C) is the maximum cross-correlation between the current frame and the next frame, and N [member of] {8N, 20N}.
