Effect of Nonlinear Elasticity on the Swelling Behaviors of Highly Swollen Polyelectrolyte Gels

open access: yesGels, 2021
Polyelectrolyte gels exhibit swelling behaviors that are dependent on the external environment. The swelling behaviors of highly charged polyelectrolyte gels can be well explained using the Flory–Rehner model combined with the Gibbs–Donnan effect and ...

Application of the parametrical surface-wave prediction model to rapidly varying wind fields during JONSWAP 1973

open access: yes, 1979
The capability of a parametrical surface wave model to predict the sea state on a small array for highly variable wind fields is shown for three examples.

A multifunctional dynamic voltage restorer for power quality improvement [PDF]

open access: yes, 2018
Power quality is a major concern in electrical power systems. The power quality disturbances such as sags, swells, harmonic distortion and other interruptions have an impact on the electrical devices and machines and in severe cases can cause serious ...

Depth Inversion Using SAR and Super-Resolution Enhancement: A Case Study on Case II Waters

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Depth inversion is crucial for ocean exploration, with synthetic aperture radar (SAR) technology being a key tool due to its all-weather capabilities. However, SAR-based depth inversion typically has limited resolution, ranging from hundreds to thousands

Bathymetry of the Pacific plate and its implications for thermal evolution of lithosphere and mantle dynamics [PDF]

open access: yes, 2015
A long-standing question in geodynamics is the cause of deviations of ocean depth or seafloor topography from the prediction of a cooling half-space model (HSC).
