Estimation of parameters of heterogeneous concrete by non-contact method of surface waves : studies of role of frequency range

Radoslaw Drelich, Mariusz Kaczmarek, Bogdan Piwakowski

This work is devoted to study of the influence of selection of frequency range of dispersion curve of surface waves on estimation efficiency of shear wave velocities and thickness of inhomogeneous concrete cover. The non-contact ultrasonic method, signal processing and numerical optimization...

Influence of frequency range of surface waves on estimation of parameters of heterogeneous concrete using non-contact method

Radoslaw Drelich, Bogdan Piwakowski, Mariusz Kaczmarek

This work is focused on studies of influence of selection of the frequency range of dispersion curves of surface waves on efficiency of estimation of the bulk elastic wave velocities and thickness of layers of non-homogeneous concrete. The experimental data comes from non-contact ultrasonic method...

On the use of signal modelling techniques for simulating 1/ fβ –noise

Youcef Ferdi, Mohamed Reda Lakehal, Abdelmalik Taleb-Ahmed

This paper presents a comparison study between various signal modeling techniques, combined with power series expansion to design infinite impulse response (IIR) filters based on fractional integration for 1/fβ sequences synthesis. It was found that the approximation accuracy of the power spectra,...
