Hybrid Control of Grid-Feeding and Fuzzy Logic Fault Detection in Solving Voltage Dynamic Problem within the Malaysian Distribution Network

Energies, 2021
The stochastic behavior of PV together with high PV penetration have given rise to power quality concerns involving voltage dynamic issues such as undervoltage, overvoltage, sag and swell.

Relationship between Large-Scale Variability of North Pacific Waves and El Niño-Southern Oscillation

Journal of Marine Science and Engineering, 2023
Ocean waves are crucial for driving various oceanic processes. In this study, the spatial and temporal distribution of significant wave height (SWH) in the North Pacific (NP) is analyzed using the 42-year ERA5 reanalysis dataset from European Centre for ...

Experimental Evidence of Swell Signatures in Airborne L5/E5a GNSS-Reflectometry

Remote Sensing, 2020
As compared to GPS L1C/A signals, L5/E5a Global Navigation Satellite System-Reflectometry (GNSS-R) improves the spatial resolution due to the narrower auto-correlation function. Furthermore, the larger transmitted power (+3 dB), and correlation gain (+10

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

Gels, 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 ...

“Swelling Chlorite”

Géotechnique, 1950
Synopsis On examination, two samples of clay from Keuper marls have been found to contain a chloritic mineral showing a limited c-axis expansion on glycerol treatment. One of these samples gives the same (001) spacing as montmorillonoids when treated with glycerol, and a heating test is necemary to make the distinction.
