Physically Consistent 2D to 3D Pore Space Synthesis: 1. Dynamic Grain Packing Under Strict Morphology Constraints
Dmitry Kulygin, Andrey Ananev, Aleksey Khlyupin
The 3D digital reconstruction of multi-scale, heterogeneous porous media is traditionally limited by the resolution boundaries and artifacts of X-ray computed tomography (XCT). Thi…
Structure-Informed Bayesian Inference of Anomalous Transport and Hidden Molecular Trapping in Amorphous Media
Andrey Ananev, Maria Potapova, Nikolay Kondratyuk +2
Molecular diffusion in fluctuating amorphous and macromolecular media governs key transport processes across soft-matter physics, energy storage, and biological membranes. Extracti…
Objective-Sensitive Principal Component Analysis for High-Dimensional Inverse Problems
Maksim Elizarev, Andrei Mukhin, Aleksey Khlyupin
We present a novel approach for adaptive, differentiable parameterization of large-scale random fields. If the approach is coupled with any gradient-based optimization algorithm, i…
Adaptive Strategies For Efficient Model Reduction In High-Dimensional Inverse Problems
Andrei Mukhin, Aleksey Khlyupin
This work explores a novel approach for adaptive, differentiable parametrization of large-scale non-stationary random fields. Coupled with any gradient-based algorithm, the method…
