Contrasting Symmetric Porosity and Porosity
Journal of Applied Analysis, 1998The aim of the paper is to compare the behaviour of sets with respect to symmetric porosity and porosity. The authors have found several similarities as well as several differences.

Porosity in the pastes of composite resins before and after polymerization has been measured. The influence of the diameter of the extrusion orifices and the spatulation of the chemically-activated pastes has been evaluated. Considering that thin layers of these materials are transparent, the investigation has been carried out mainly by analysis of ...

We give a short overview of dimensional properties of porous sets and measures. A special emphasis is given to the heuristic ideas behind a recent result giving the best possible upper bound for the packing dimension of mean porous measures. This chapter is based on the paper Beliaev et al. (J Lond Math Soc, 2009), which is a joint work with D. Beliaev,

Shrinkage Porosity and Gas Porosity
2008Abstract This article provides a detailed discussion on the causes of formation of shrinkage porosity and gas porosity along with the methods involved in eliminating them. It discusses the process of porosity formation and the factors affecting porosity formation, including alloy composition, external pressure, and cooling conditions.

Porosity Supremum-Infimum and Porosity Convergence
2017In this paper, by using porosity notion for subsets of natural numbers at infinity porosity lower and porosity upper bound of real valued sequences will be defined. By using these new notions, definitions of porosity infimum and porosity supremum will be given, respectively.
