Damping Studies on PMLG-Based Wave Energy Converter under Oceanic Wave Climates
Energies, 2021 Wave energy converters (WECs), which are designed to harvest ocean wave energy, have recently been improved by the installation of numerous conversion mechanisms; however, it is still difficult to find an appropriate method that can compromise between ...

Nonlinear Wave Evolution in Interaction with Currents and Viscoleastic Muds
Journal of Marine Science and Engineering, 2021 A numerical model is extended to investigate the nonlinear dynamics of surface wave propagation over mud in the presence of currents. A phase-resolving frequency-domain model for wave-current interaction is improved to account for wave modulations due to

Pseudospectra of the Damped Wave Equation with Unbounded Damping [PDF]
SIAM Journal on Mathematical Analysis, 2020 We analyze pseudospectra of the generator of the damped wave equation with unbounded damping. We show that the resolvent norm diverges as $\Re z \to - \infty$. The highly non-normal character of the operator is a robust effect preserved even when a strong potential is added.

Influence of the upper gravity-wave damping layer on precipitation over complex terrain
Frontiers in Environmental Science, 2022 The upper boundary condition of a numerical model can significantly influence the model prediction results. This study used the Weather Research and Forecasting model to introduce the Rayleigh damping layer in the complex terrain of southern Gansu, China.

Models for Damped Water Waves [PDF]
SIAM Journal on Applied Mathematics, 2019 In this paper we derive some new weakly nonlinear asymptotic models describing viscous waves in deep water with or without surface tension effects. These asymptotic models take into account several different dissipative effects and are obtained from the free boundary problems formulated in the works of Dias, Dyachenko and Zakharov (Physics Letters A ...

4.2 Biological and Vascular Contributors to Cerebral Pulsatility and Pulsatile Damping
Artery Research, 2020 Cerebral pulsatility is an emerging contributor to brain health that reflects the balance between the transmission and damping (i.e. attenuation) of pulsatility through extracranial vessels into the cerebrovasculature.
