Study of the numerical simulation of tight sandstone gas molecular diffusion based on digital core technology
Tight sandstone gas Nano-CT Digital core Molecular diffusion Numerical simulation
2018/4/2
Diffusion is an important mass transfer mode of tight sandstone gas. Since nano-pores are extensively developed in the interior of tight sandstone, a considerable body of research indicates that the t...
Correction of source-rock permeability measurements owing to slip flow and Knudsen diffusion: a method and its evaluation
Shale gas Permeability Knudsen diffusion Unconventional reservoir Source rock
2018/4/2
Source-rock permeability is a key parameter that controls the gas production rate from unconventional reservoirs. Measured source-rock permeability in the laboratory, however, is not an intrinsic prop...
LIGHT DIFFUSION IN THE TROPICAL DRY FOREST OF COSTA RICA
Leaf area index spectral vegetation indices MODIS
2016/11/30
Leaf Area Index (LAI) has been defined as the total leaf area (one-sided) in relation to the ground. LAI has an impact on tree growth and recruitment through the interception of light, which in turn a...
Sulfuric acid recovery from titanium white (pigment) waste liquor using diffusion dialysis with a new series of anion exchange membranes—static runs
Ion exchange membrane Diffusion dialysis Titanium white waste liquor Poly(2,6-dimethyl-1,4-phenylene oxide)
2016/3/25
In this paper, a new series of anion exchange membranes have been produced from linear engineering plastics poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) by conducting the processes of bromination, chl...
Indifferentiability of Confusion-Diffusion Networks
Indifferentiability Confusion-Diffusion Networks
2016/1/22
We show the first positive results for the indifferentiability security of the confusion-diffusion networks (which are extensively used in the design of block ciphers and hash functions).In particular...
DynaDiffuse: A Dynamic Diffusion Model for Continuous Time Constrained Influence Maximization
A Dynamic Diffusion Model Constrained Influence Maximization
2016/1/22
Studying the spread of phenomena in social networks is critical but still not fully solved. Existing influence max-imization models assume a static network, disregarding its evolution over time. We in...
New Trends in Digital Photogrammetry Teaching and Diffusion:The Z-GLIF Software
Photogrammetry Architecture Teaching Software Digital Experience
2015/11/11
Many experiences have been done in the past in order to promote a wide diffusion of the photogrammetry both in teaching and professional works.
Only the digital evolution allowed a real step forward...
Mars Express is in orbit for over two years and has returned more than 1.000 image strips to earth taken by the multiple line scanner
camera HRSC (High Resolution Stereo Camera). The three-dimensiona...
SEGMENTATION AND OBJECT EXTRACTION FROM ANISOTROPIC DIFFUSION FILTERED LIDAR INTENSITY DATA
LiDAR Intensity Image Anisotropic Diffusion Segmentation Object-Based Classification
2015/8/19
LiDAR technology provides two different kinds of data: elevation, obtained by differences in time of the emitted and received laser signal; and intensity, obtained by differences of reflected laser be...
A space-time diffusion scheme for peer-to-peer least-squares estimation
distributed algorithms sensor networks least-squares estimation
2015/8/10
We consider a sensor network in which each sensor takes measurements, at various times, of some unknown parameters, corrupted by independent Gaussian noises. Each node can take a finite or infinite nu...
