Meticulous quality control of the post-processed data was fundamental in this study and evidence of aberrant pathlines indicating data imperfections was carefully sought.
This process is designed to yield an evidence metric that has utility when etiologic heterogeneity, variable risk factor frequencies, and a variety of observational data imperfections might lead to false conclusions.
If pathlines leave the blood pool at locations incompatible with the actual blood flow, e.g. leaving the LV through the ventricular apex, this is an indication of data imperfections.
The effects of the choice of the cost function, frequency resolution of data and imperfections in experiments are discussed.
Next, the signal preprocessing techniques used for enhancing the measured AE signals in the presence of noise and data acquisition imperfections are presented.
And with that twin track, we should have the highest ambition to turn all our data from imperfect to best quality – but never let imperfection slow us down.
Despite this partiality and imperfection, data generated by public bodies can be the best source of information we have on a given topic and can be augmented with other data sources, documents and external expertise.

These advances include a hierarchical analysis strategy that includes analyses that range from classical analysis methods to high-fidelity nonlinear finite element analysis methods, reliability based design methods, the development of imperfection data bases, and the identification of traditional and nontraditional initial imperfections for composite shell structures.
Detailed information about the geometrical data, measured geometrical imperfections, temperature, load and actual mechanical properties were collected.
