Unlike the Fourier theory that lacks scaling and translation parameters, the wavelet theory provides a new platform for the so-called de-oising workflow where noise in a signal or set of data is reduced. This work demonstrates how the wavelet transform can be used as a de-noising tool to denoise pressure transient data for PTA. The target is to create a smoother yet representative data pattern out of a noisy set of data. Two flow regimes were clearly identified from a noisy set of pressure transient data – spherical and radial flow regimes. The data points were then fitted to simple mathematical models describing spherical and radial flows. The p-values from the Chi-squared distributions were less than 0.05, indicating a perfect fit of the data points to the models.
This study examined how chloride environments impact the mechanical properties of steel in CPC and OPC concretes. SEM and XRD tests confirmed surface morphology changes and varying strength under corrosion.
