I wish to develop the phenomenological diffusion model of interaction of gravitational waves on water surface in presence of wind and viscosity. Motivation for development of such a model is the fact that numerical solvers based on Hasselmann kinetic equation for waves are time-consuming and hardly can be used for practical purposes. Numerical solver based on the diffusion model is expected to ...

Functional dyspepsia is a clinical syndrome defined by chronic or recurrent symptoms of pain or discomfort centred upon the upper abdomen without a cause being identified by conventional diagnostic means. 1 The pathophysi-ology of functional dyspepsia is unknown but a number of mechanisms have been proposed, such as delayed gastric emptying, hypersensitivity to gastric distension, impaired acco...

Significant wave height (SWH) stems from a combination of locally generated “wind-sea” and remotely “swell” waves. In the Northern Southern Hemispheres, heights typically undergo sinusoidal annual cycle, with larger SWH in winter response to seasonal changes high-latitude storm patterns that generate equatorward propagating swell. However, some locations deviate this hemispheric-scale pattern S...

This article attempts to analyze the influence of anisotropic effects ocean wave surface on SAR altimetry backscatter coefficient (Sigma-0) measurements, which has not been intensively addressed in publications. Data Sentinel-3A, Cryosat-2, and Jason-3 altimeters allocated by WW3 numeric model were analyzed, patterns Sigma-0 with respect direction acquired under ∼2 m significant height. The wav...

Variations of marine current speed can lead to strong fluctuations in the power extracted by a marine current turbine (MCT). During short-time period, swell effect is the main cause for the current speed variations. Conventional tip speed ratio Maximum Power Point Tracking (MPPT) algorithm will require the MCT to accelerate or to decelerate frequently under swell effect, which can cause severe ...
