Anisotropic Diffusion in Driven Convection Arrays [PDF]
Entropy, 2021 We numerically investigate the transport of a Brownian colloidal particle in a square array of planar counter-rotating convection rolls at high Péclet numbers. We show that an external force produces huge excess peaks of the particle’s diffusion constant

Anisotropic Diffusion of Elongated Particles in Active Coherent Flows [PDF]
MicromachinesThe study of particle diffusion, a classical conundrum in scientific inquiry, holds manifold implications for various real-world applications. Particularly within the domain of active flows, where the motion of self-propelled particles instigates fluid ...

Multidimensional encoding of restricted and anisotropic diffusion by double rotation of the q vector [PDF]
Magnetic Resonance, 2023 Diffusion NMR and MRI methods building on the classic pulsed gradient spin-echo sequence are sensitive to many aspects of translational motion, including time and frequency dependence (“restriction”), anisotropy, and flow, leading to ambiguities when ...

Anisotropic Diffusion Based Multiplicative Speckle Noise Removal [PDF]
Sensors, 2019 Multiplicative speckle noise removal is a challenging task in image processing. Motivated by the performance of anisotropic diffusion in additive noise removal and the structure of the standard deviation of a compressed speckle noisy image, we address ...

The Normal Cross Numerical Method Used to Solve the Anisotropic Diffusion Problem
Journal of Harbin University of Science and Technology, 2020 In order to solve the two dimensional anisotropic diffusion problem, an efficient normal crossing numerical method was proposed. The program was written in FORTRAN language to realize numerical calculation.
