This monograph contains the advances achieved based on the content of our previous
monograph published in 2011. In other words, the present monograph can be considered …

Natural time analysis enables the introduction of an order parameter for seismicity, which is
just the variance of natural time χ, κ 1=〈 χ 2〉−〈 χ〉 2. During the last years, there has been …

This work focuses on an experimental and numerical investigation into monitoring damage
in a cube-shaped concrete specimen under compression. Experimental monitoring uses …

This study aims to explore the possibility of detecting indices that could potentially provide
warning about the proximity of internal damage to critical levels, beyond which catastrophic …

This work investigates the extension of a total-collapse prediction method to include local
failures in quasi-brittle materials as they undergo damage processes. The analysis is …

The acoustic activity, generated in notched, beam-shaped concrete specimens, loaded
under three-point bending, is studied in terms of the position of the sources of acoustic …

The acoustic activity developed in marble specimens under various loading schemes is
explored in terms of the recently introduced F-function. The novelty of the study is that …

Since April 2023 an in situ experimental campaign has been underway in a granite
underground tunnel, which is a dedicated monitoring platform located in Southeast China …

A novel approach for describing the acoustic activity in brittle structural materials while they
are loaded mechanically at levels close to those causing macroscopic fracture is proposed …

The attenuation of the acoustic activity in marble specimens under uniaxial compressive
loading-unloading loops is quantified in juxtaposition to that of the electric activity. In …
