On Nonlinear Water Waves in a Channel

Low-frequency excitations in a molecular glass: Single-particle dynamics.

The low-frequency dynamics of a molecular glass former has been investigated by means of inelastic neutron scattering &om a mostly incoherent sample as well as by computer molecular-dynamics simulation. The mode assignments have been carried out using the neutron data for the polycrystal as well as by means of the analysis of the density of states (DOS) computed from a lattice-dynamics calculat...

Low Frequency Waves in the Santa Barbara Channel Observed by High Frequency Radar

[1] Three years of high-frequency radar observations in the Santa Barbara Channel reveal sequences of alternating cyclonic and anticyclonic vortices propagating westward with a period of approximately 2 weeks. The sequences last up to a few months and occur intermittently throughout the year. The velocity distributions of cyclones and anticyclones are antisymmetric with a mean propagation speed...

High sensitive vectorial B-probe for low frequency plasma waves.

A miniaturized multidimensional magnetic probe is developed for application in a low-temperature plasma environment. A very high sensitivity for low-frequency magnetic field fluctuations with constant phase run, a very good signal-to-noise ratio combined with an efficient electrostatic pickup rejection, renders the probe superior compared with any commercial solution. A two-step calibration all...

High frequency poroelastic waves in hydrogels.

In this work a continuum model for high frequency poroelastic longitudinal waves in hydrogels is presented. A viscoelastic force describing the interaction between the polymer network and the bounded water present in such materials is introduced. The model is tested by means of ultrasound wave speed and attenuation measurements in polyvinylalcohol hydrogel samples. The theory and experiments sh...
