1 Method of calculation ofPkδ The calculation ofPkδis straightforward, being a discrete Fourier transform of the functionδndefined by Eq. (9). As seen in Fig.2when calculatingPkδaveraged over an ensemble one obtains sets of points which present a smooth behavior. When calculatingPkδfor ...
In the present work, the whole process of measurement of the elastic moduli by BS is critically analyzed: experimental setup, data recording, calibration, and calculation of the elastic moduli. It is shown that combining BS with ellipsometry a fully optical characterization can be obtained. The ...
the percent uncertainty in a quantity calculated by multiplication or division is the sum of the percent uncertainties in the items used to make the calculation percent uncertainty: the ratio of the uncertainty of a measurement to the measured value, expressed as a percentage precision: the degree...

The measured STD is higher than the theoretically predicted value, and we investigated four possible factors which explain this discrepancy. First, it is shown that the STD and bias after spectrogram calculation are rather insensitive to changes in windowing function, type, length and overlap. ...
Accuracy and precision are only two important concepts used in scientific measurements. Two other important skills to master aresignificant figuresandscientific notation. Scientists usepercent erroras one method of describing how accurate and precise a value is. It's a simple and useful calculation....
