A large number of the vocalization studies on mammals are based on time-frequency analysis of the produced sounds. The patterns, which are extracted from the time-frequency representations, determine the classification in ...
[EN] In this study, complete ultrasonic monitoring of Glass-fiber Reinforced Cement plates under bending tests was addressed. In this kind of experiment, the mechanical properties of the specimen continuously change during ...
New applications of non-destructive techniques (NDT) with ultrasonic tests (attenuation and velocity by means of ultrasonic frequency sweeps) have been developed for the characterization of fibre-reinforced cementitious ...
[EN] In this paper, a new approach for characterizing material damage, using ultrasonic waves, is proposed. Two
concrete series with two types of cement with different C3A content and similar mechanical properties ...
[EN] One-class detector is an option to deal with the problem of detecting an unknown signal
in a background noise, as it is only necessary to know the noise distribution. Thus a
Gaussian copula is proposed to capture ...
