We investigate the conductivity variation with density of compacted vapour-grown carbon fibre (VGCF). The results indicate a typical transition between a non-linear domain at low compaction conditions and a regime where the conductivity increases roughly linearly with density when the sample is...

We study the oil displacement and production behavior in an isothermal thin layered reservoir model subjected to water flooding. We use the CMG’s (Computer Modelling Group) numerical simulators to solve mass balance equations. The influences of the viscosity ratio (m≡μoil/μwater) and the...

This paper presents seven results on irregular systems that are both new and can be described simply. The first three results are related to dynamical and static properties of gradient percolation. Firstly, it is shown that the transient regimes which lead to self-organized gradient percolation...
