In this paper, several important guided wave mode attributes are introduced in addition to the commonly used phase velocity and group velocity dispersion curves while using the general corrosion problem as an example. We first derive a simple and generic wave excitability function based on the ...
A problem in the identification of MIMO systems is that the system outputs in an identification experiment may be strongly correlated if the inputs are perturbed by uncorrelated signals, as is standard practice. Such a correlation reduces identifiability. A set of methods to design input perturbation...
p shows the scale of the distribution as a simple curve in the plane, which is easily visualized and interpreted. It is used in LPS as a simple visual tool for comparing the efficiency of different estimators when they are all used to estimate the same multivariate parameter, e.g. using ...

Step 6:Divide the numberyou calculated in Step 6by the square root of the sample size(in this sample problem, the sample size is 5): 8.257 / √(5) = 8.257 / 2.236 = 3.693 That’s how to calculate the standard error for the sample mean!
calculation and verification work of first round sample problem, which was intended to test the engineering application of environmentally assisted fatigue (EAF) using the Fen correction factor method of Code Case N-792 Rev.O and the proposed Code Case for evaluation of strain rate in EAF ...
Additionally, sample size significantly influences the performance of classifiers, as seen in our results and in a review study that the large sample sizes depict relatively precise and similar accuracies among classifiers [47]. Taken together, both simple size and datatype affect the performance ...
In dielectric analysis measurements, since ε∞ cannot be measured directly, the curve is usually extrapolated, and the value is determined graphically (numerically). The resulting plot, depicted in Figure 4, is called a Debye semicircle, and it is useful to determine if a system has only one...
This note explores the frequently encountered problem that a tuneseries formed as an average of a sample of individr4al timeseries has a variance that depends upon the size of the sample. Methods for adjusting the timeseries to reduce this uar2bnce bias are demonstrated-first a simple one and...
