The approach is based on the information entropy (IE) theory and division of the signal (photon counts, differential or gauge pressure fluctuations) into different regions.
Moreover, the slip distributions observed with the DIC technique showed similarities to those obtained from the strain gauges, despite some fluctuations, i.e. with higher slips at the SS loaded end and decreasing towards the SS free end.
Some tide gauge records, including tsunami fluctuations, were obtained from sites near and far from the source region, such as in Panama, Japan, and the USA.
The barometers they follow closely are gauges of volatility, or fluctuations in the prices of stocks and options.
On a larger scale, economists say the effect of the antismuggling campaign can be gauged by the wild fluctuations in prices and revenues associated with formerly smuggled goods during the last year.
While systematic errors are introduced by an inaccuracy inherent in the system such as imperfect performance (or calibration) of measurement gauges, random errors are caused by unpredictable fluctuations in the reading of gauges.
In addition, it could theoretically then layer on databases that tracked current events, like news headlines on the Internet or weather fluctuations, to try to gauge how such factors interplay with the financial data.
Downhole pressure transient measurements are usually affected by random noise caused by the intrinsic noise of the measuring device (the pressure gauge), environmental noise, and/or wellbore pressure fluctuations.
Hourly data are highly noisy due to, e.g., non-physical temperature-based fluctuations of the signal or gauge under-catch.
However, the statistical isotropy of fluctuations is spontaneously broken by gauge modes whose wavelength exceeds our causal horizon.
