Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Domain Decomposition and Optimized Schwarz Methods for the Dual-porosity-conduit System
双重孔隙 导管系统 区域分解 优化Schwarz方法
2023/5/10
In this work, we propose and analyze domain decomposition methods to decouple the large system arisen from the discretization of dual-porosity-Stokes model. Robin boundary conditions are used to decou...
Porosity and Lithology Prediction in Eve Field, Niger Delta Using Compaction Curves and Rock Physics Models
Compaction Trend Lithology Porosity Reservoir Characteristic
2013/3/7
The primary objective of this study is to investigate the porosity-depth trends of shales and sands and how they affect lithologies. Compaction curves from well logs of five wells were determined usin...
Effect of surfactant on porosity and swelling behaviors of guar gum-g-poly(sodium acrylate-co-styrene)/attapulgite superabsorbent hydrogels
Surfactant Porosity Guar gum Hydrogel Swelling behavior
2011/10/10
Novel fast-swelling porous guar gum-g-poly(sodium acrylate-co-styrene)/attapulgite (GG-g-P(NaA-co-St)/APT) superabsorbent hydrogels were prepared by simultaneous free-radical graft copolymerization re...

Surfactant Porosity Guar gum Hydrogel Swelling behavior
2011/12/14
Novel fast-swelling porous guar gum-g-poly(sodium acrylate-co-styrene)/attapulgite (GG-g-P(NaA-co-St)/APT) superabsorbent hydrogels were prepared by simultaneous free-radical graft copolymerization re...
Representative elementary area for multifractal analysis of soil porosity using entropy dimension
Representative elementary area multifractal analysis soil porosity entropy dimension
2009/11/3
The notion of representative elementary area (REA) developed to address heterogeneity and scale problems in quantitative soil pedology comes from the notion of representative elementary volume of flui...
A KIND OF STRUCTURE MODELS FOR DOUBLE POROSITY MEDIUM SYSTEMS AND ITS IDENTIFICATION PROBLEMS
2007/8/7
This paper studies problems of modeling and simulation for infinite-dimensional systems. In early 1960's, G. I. Barenblatt and the others proposed the well-known permeable models through double porous...

The specific surface area (SSA) of clay minerals and related materials is one of their most important properties controlling surface phenomena. The SSA of nonswelling and non-microporous phyllosilicat...
Corrosion of Reinforcing Steel in Concrete Immersed in Chloride Solution and the Effects of Detergent Additions on Diffusion and Concrete Porosity
Corrosion Reinforcing Steel Concrete Immersed Effects of Detergent Additions
2010/4/22
In order to investigate the corrosion of reinforcing steel in concrete and the effects of chloride ions, oxygen diffusion and detergent additives of linear alkylbenzene (LAB) and linear alkylbenzene s...
Porosity-Size Relationship of Drilling Mud Flocs: Fractal Structure
Drilling mud Flocs Fractal Porosity
2011/12/29
The porosities of flocs formed from a used drilling mud were determined by measuring sizes and settling speeds of individual flocs. These flocs were produced in a Couette-type flocculator under a vari...
