Acoustic Emission (AE) method, widely used for non-destructive evaluation and material characterization, is very beneficial for monitoring of highly dynamic damage processes. Computational power of contemporary regular hardware enables to test the new approaches in this field as it could not be done before without the capability of continuous signal recording and analysis. Modern portable...
This paper focuses on the application of Preisach-Mayergoyz (PM) model applied to the evaluation of the elastic properties of the material. In the first section, there are explained basic vital terms, such as hysteresis, and it’s properties, optimization algorithms, suitable probability density functions and $\phi$-divergences. This knowledge is implemented in the presented program designed to...
This paper focuses on extraction of a moving source of interest (SOI) form a linear mixture. The rest of the mixture is called the background. The parameterization of the mixture is designed according to a well-known independent component analysis (ICA) model, although, ICA deals only with static mixtures. Thus, the extension to dynamic sources is completely novel. The model dynamics is...
