DeepAngle: Fast calculation of contact angles in tomography images using deep learning

1 code implementation28 Nov 2022 Arash Rabbani, Chenhao Sun, Masoud Babaei, Vahid J. Niasar, Ryan T. Armstrong, Peyman Mostaghimi

DeepAngle is a machine learning-based method to determine the contact angles of different phases in the tomography images of porous materials.

A comparative study of paired versus unpaired deep learning methods for physically enhancing digital rock image resolution

no code implementations16 Dec 2021 Yufu Niu, Samuel J. Jackson, Naif Alqahtani, Peyman Mostaghimi, Ryan T. Armstrong

Recent developments in super resolution (SR) methods using deep learning allow the digital enhancement of low resolution (LR) images over large spatial scales, creating SR images comparable to the high resolution (HR) ground truth.

Generative Adversarial Network Image Enhancement +2

Deep learning of multi-resolution X-Ray micro-CT images for multi-scale modelling

1 code implementation1 Nov 2021 Samuel J. Jackson, Yufu Niu, Sojwal Manoorkar, Peyman Mostaghimi, Ryan T. Armstrong

The SR images and models are comparable to the HR ground truth, and generally accurate to within experimental uncertainty at the continuum scale across a range of flow rates.

Thermodynamics of fluctuations based on time-and-space averages

no code implementations16 Dec 2020 James E. McClure, Steffen Berg, Ryan T. Armstrong

We show that while any stationary process can be represented as having zero entropy production, second law constraints due to the Clausius theorem are preserved due to the fact that heat and work are related based on conservation of energy.

ML-LBM: Machine Learning Aided Flow Simulation in Porous Media

1 code implementation22 Apr 2020 Ying Da Wang, Traiwit Chung, Ryan T. Armstrong, Peyman Mostaghimi

In the tortuous flow paths of porous media, Deep Learning techniques based on Convolutional Neural Networks (CNNs) are shown to give an accurate estimate of the steady state velocity fields (in all axes), and by extension, the macro-scale permeability.

Physical Accuracy of Deep Neural Networks for 2D and 3D Multi-Mineral Segmentation of Rock micro-CT Images

1 code implementation13 Feb 2020 Ying Da Wang, Mehdi Shabaninejad, Ryan T. Armstrong, Peyman Mostaghimi

Segmentation of 3D micro-Computed Tomographic uCT) images of rock samples is essential for further Digital Rock Physics (DRP) analysis, however, conventional methods such as thresholding, watershed segmentation, and converging active contours are susceptible to user-bias.
