Segmentation of pores in cementitious materials based on backscattered electron measurements: a new proposal of regression-based approach for threshold estimation
Autor: Żak, Andrzej M., Wieczorek, Anna, Chowaniec, Agnieszka, Sadowski, Lukasz
Publikováno v: Construction and Building Materials 368 (2023) 130419
In the following work, we described the problems of porosity analysis of cement materials using backscattered electron images. We noticed that despite its great utility, the overflow porosity segmentation method allows for the introduction of an addi

The method of assessing porosity using images from scanning electron microscopy is ineffective in situations where the substrate and the coating have a significantly different average atomic number, which results in a different contrast of backscatte

Constructing sparsest $\ell$-hamiltonian saturated $k$-uniform hypergraphs for a wide range of $\ell$
Autor: Ruciński, Andrzej, Żak, Andrzej
Publikováno v: European J. Combin., 109 (2023) 103659
Given $k\ge3$ and $1\leq \ell< k$, an $(\ell,k)$-cycle is one in which consecutive edges, each of size $k$, overlap in exactly $\ell$ vertices. We study the smallest number of edges in $k$-uniform $n$-vertex hypergraphs which do not contain hamiltoni
