Image compression with anisotropic diffusion [PDF]

, 2008
Compression is an important field of digital image processing where well-engineered methods with high performance exist. Partial differential equations (PDEs), however, have not much been explored in this context so far. In our paper we introduce a novel

Dual-Functional Coding Metasurfaces Made of Anisotropic All-Dielectric Resonators

IEEE Access, 2019
Digital coding metasurfaces, composed of only two types of unit cells with opposite phase responses (0 and π) that can map to the usual binary elements “0” and “1”, are capable of generating coded pulsed sequences of ...

Anisotropic Cardiac Conduction [PDF]

, 2020
Anisotropy is the property of directional dependence. In cardiac tissue, conduction velocity is anisotropic and its orientation is determined by myocyte direction.

Anisotropic, biomorphic cellular Si3N4 ceramics with directional well-aligned nanowhisker arrays based on wood-mimetic architectures

Journal of Advanced Ceramics, 2022
Inspired by the transport behavior of water and ions through the aligned channels in trees, we demonstrate a facile, scalable approach for constructing biomorphic cellular Si3N4 ceramic frameworks with well-aligned nanowhisker arrays on the surface of ...

A 3D Anisotropic Thermomechanical Model for Thermally Induced Woven-Fabric-Reinforced Shape Memory Polymer Composites

Sensors, 2023
Soft robotic grippers offer great advantages over traditional rigid grippers with respect to grabbing objects with irregular or fragile shapes. Shape memory polymer composites are widely used as actuators and holding elements in soft robotic grippers ...

Modeling the Thermal Performance of Anisotropic Heat Conduction Fabric with Different Structural Parameters

Journal of Natural Fibers, 2023
Differences in yarn and fabric structures lead to different thermal properties of the fabric, and even the thermal comfort of the textile. The heat transfer model of the cotton woven fabric with different structural parameters was established by ...

Quantifying scaling in the velocity field of the anisotropic turbulent solar wind [PDF]

, 2007
Solar wind turbulence is dominated by Alfvénic fluctuations with power spectral exponents that somewhat surprisingly evolve toward the Kolmogorov value of −5/3, that of hydrodynamic turbulence.
