The wave spectrum in archipelagos [PDF]
Ocean Science, 2019 Sea surface waves are important for marine safety and coastal engineering, but mapping the wave properties at complex shorelines, such as coastal archipelagos, is challenging. The wave spectrum, E(f), contains a majority of the information about the wave

Transformation of Water Wave Spectra into Time Series of Surface Elevation
Earth, 2021 Spectral wave modelling is widely used to simulate large-scale wind–wave processes due to its low computation cost and relatively simpler formulation, in comparison to phase-resolving or hydrodynamic models.

Temporal prediction for spectrum environment maps with moving radiation sources
IET Communications, 2023 Spectrum resources are becoming harder to come by for wireless communications. The spectrum environment map (SEM), which depicts the electromagnetic environment's current state and future trend, is a valuable technique for managing and allocating ...

Wave-Number Spectrum of Drift-Wave Turbulence [PDF]
Physical Review Letters, 2009 A simple model for the evolution of turbulence fluctuation spectra, which includes neighboring interactions leading to the usual dual cascade as well as disparate scale interactions corresponding to refraction by large scale structures, is derived. The model recovers the usual Kraichnan-Kolmogorov picture in the case of exclusively local interactions ...
