Porosity, -porosity and measures [PDF]
Nonlinearity, 2002 We show that given a σ-finite Borel regular measure μ in a metric space X, every σ-porous subset of X of finite measure can be approximated by strongly porous sets. It follows that every σ-porous set is the union of a σ-strongly porous set and a μ-null set.

Constraints on porosity and mass loss in O-star winds from modeling of X-ray emission line profile shapes [PDF]
, 2013 We fit X-ray emission line profiles in high resolution XMM-Newton and Chandra grating spectra of the early O supergiant Zeta Pup with models that include the effects of porosity in the stellar wind.

A mass-loss rate determination for zeta Puppis from the quantitative analysis of X-ray emission line profiles [PDF]
, 2009 We fit every emission line in the high-resolution Chandra grating spectrum of zeta Pup with an empirical line profile model that accounts for the effects of Doppler broadening and attenuation by the bulk wind.

Modelling urban floods using a finite element staggered scheme with porosity and anisotropic resistance [PDF]
, 2018 Artificial porosity models for urban flooding use porosity as a statistical descriptor for the presence of buildings, which are then treated as subgridscale features. Computational efficiency makes porosity models attractive for large-scale applications.

A study of the porosity of nuclear graphite using small-angle neutron scattering [PDF]
, 2013 Small angle neutron scattering (SANS) measures porosity in nuclear graphites, including both open pores, caused by escaping decomposition gases, and internal cracks (in coke particles) generated by anisotropic thermal contraction along the c-direction ...

Variations of porosity in calcareous sediments from the Ontong Java Plateau [PDF]
, 1993 Based on index properties measurements made on board the JOIDES Resolution, we studied porosity changes with depth in the fairly homogeneous deep-sea calcareous sediments cored during Ocean Drilling Program Leg 130 on the Ontong Java Plateau.

Salt crystallisation at the surface of a heterogeneous porous medium [PDF]
, 2012 Evaporation of saline solutions from a porous medium often leads to the precipitation of salt at the surface of the porous medium. It is commonly observed that the crystallized salt does not form everywhere at the porous medium surface but only at some ...
