Contrasting Symmetric Porosity and Porosity

Journal of Applied Analysis, 1998
The 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.

Shrinkage Porosity and Gas Porosity

2008
Abstract 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.

Multiple-porosity Variable Critical Porosity Model

Proceedings, 2015
Compared with conventional reservoirs, complex reservoirs often have more variety of pore types and more complex pore shape. For example, carbonate rocks can have a variety of pore types, such as moldic, vuggy, interparticle, intraparticle and crack.

Evaluating Porosity Parameters for Porosity–Property Relations

Journal of the American Ceramic Society, 1993
Porosity parameters are considered from the standpoint of a map of the volume fraction porosity (P) and the ratio of normalized radii of the pore ( r p ) and the solid particles, webs, or ligaments ( r

Dimensions and Porosities

2010
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,
