Unloading arms (ULAs) among seaport infrastructures are susceptible to deterioration posed by the effects of harsh marine environmental conditions. During infrastructure’s service life, structural integrity may increase risk failure infrastructure, and should be taken into account during reliability assessment. In this study, a simple non-destructive test (NDT) was employed examine ULAs which w...

DNA barcodes are short sequences of nucleotides that differ from species to species (Hebert et al., 2003; Hebert & Gregory, 2005). DNA barcoding is very important in helping to reconstruct phylogenetic trees and to confirm the identity of threatened or endangered species in the wild. Additionally, it has become increasingly popular in the food industry to test the accuracy of the food being sol...

In this paper we compare the effectiveness of the time, wavelet and Hilbert Huang domain analysis of waveforms from a Non Destructive Test (NDT) equipment. The analysis of the signals from NDT systems is one of the most important activities since it allows to locate the actual defects. Very often the echoes traveling back to the sensors are superimposed with the signal from the transducer. We a...
