Ultrasonic sensor signals and optimum path forest classifier for the microstructural characterization of thermally-aged inconel 625 alloy
(2015)
Secondary phases, such as laves and carbides, are formed during the final solidification stages of nickel-based superalloy coatings deposited during the gas tungsten arc welding cold wire process. However, when aged at ...
Beamforming echo-localization system using multitone excitation signals
(Institute of Electrical and Electronics Engineers Inc., 2017)
Determining the position of a target is the central issue in several engineering problems, from computer vision to sonar or radar systems. Echo-localization systems use the reflected sound waves to extract information from ...
Common architecture for discrete wavelet transform analysis and synthesis with sequential and constant processing elements
(2004-10-08)
This paper adresses the problem on processing biological data such as cardiac beats, audio and ultrasonic range, calculating wavelet coefficients in real time, with processor clock running at frequency of present ASIC's ...

Energy method to calculate the density of liquids using ultrasonic reflection techniques
(2001-12-01)
In this work it is introduced a new approach to calculate the density of liquids in terms of the energies of the acoustic signals. This method is compared to other methods in the time domain (peak-to-peak amplitudes) and ...
