A Regularized Shallow Water System
Evgueni Dinvay, Henrik Kalisch
The shallow-water system is a standard model for long waves in shallow water. The system is hyperbolic and, for a large class of initial data, solutions develop steep gradients lea…
Recovery of directional wave spectrum from sparse data with compressed sensing
Qingyu Jiang, Henrik Kalisch, Michel Benoit +2
Compressed sensing provides an efficient framework for reconstructing wave signals from reduced measurements. For multi-channel buoy data, the three displacement components exhibit…
Listen to the Waves: Using a Neuronal Model of the Human Auditory System to Predict Ocean Waves
Artur Matysiak, Volker Roeber, Henrik Kalisch +2
Artificial neural networks (ANNs) have evolved from the 1940s primitive models of brain function to become tools for artificial intelligence. They comprise many units, artificial n…
Infra-gravity Waves and Cross-shore Transport -- A Conceptual Study
Andreas Bondehagen, Henrik Kalisch, Volker Roeber
Infra-gravity waves are generally known as small-amplitude waves of periods between 25 seconds and 5 minutes. They originate from the presence of wave groups in the open ocean wave…
