Factors influencing the performance of rebound hammer used for non-destructive testing of concrete members: A review

open access: yesCase Studies in Construction Materials, 2021
Non-destructive testing (NDT) has a vital role in finding surface hardness of concrete members. B-Proceq curve can calculate the concrete strength by providing statistical correlations between the destructive and the non-destructive strength.

Parallel double-plate capacitive proximity sensor modelling based on effective theory

open access: yesAIP Advances, 2014
A semi-analytical model for a double-plate capacitive proximity sensor is presented according to the effective theory. Three physical models are established to derive the final equation of the sensor. Measured data are used to determine the coefficients.

Breaking the resolution limit in photoacoustic imaging using non-negativity and sparsity

open access: yesPhotoacoustics, 2020
The spatial resolution achievable in photoacoustic imaging decreases with the imaging depth, resulting in blurred images for deeper structures. Apart from technical limitations, the ultimate resolution limit results from the second law of thermodynamics.
