Low frequency oscillations of the magnetosphere [PDF]
2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014 Sudden pulses in the model solar wind sets the Earth's magnetosphere into damped oscillatory motions. A simple model is capable of explaining many of the basic properties of these oscillations, giving scaling laws for their characteristics in terms of the parameters of the problem, such as the Solar wind momentum density. The period of the oscillations,

Low frequency room excitation using Distributed Mode Loudspeakers [PDF]
, 2002 Conventional pistonic loudspeakers excite the modes of an enclosed sound field in such a way as to introduce modal artefacts which may be problematic for listeners to high-quality reproduced sound [1].

Low Frequency Oscillations on the Dutch Coast
Coastal Engineering 1984, 1984 During several months in 1981 and 1982/1983 two extensive programs of field measurements were carried out at Egmond on the Dutch North Sea coast, one during the spring of 1981 and the other during the winter of 1982/83. In these programs researchers of the Dutch "Rijkswaterstaat", of The Delft University of Technology and of the Delft Hydraulics ...

Flow over a cylinder subjected to combined translational and rotational oscillations [PDF]
, 2012 The experimental research reported here employs particle image velocimetry to extend the study of Nazarinia et al. (2009a), recording detailed vorticity fields in the near-wake of a circular cylinder undergoing combined translational and rotational ...

Low-frequency oscillations in coupled phase oscillators with inertia
Scientific Reports, 2019 AbstractThis work considers a second-order Kuramoto oscillator network periodically driven at one node to model low-frequency forced oscillations in power grids. The phase fluctuation magnitude at each node and the disturbance propagation in the network are numerically analyzed.

Data-Driven Risk Identification Method for Low-Frequency Oscillations in New Power Systems
EnergiesWith the increasing scale of new energy grid integration, the risk of low-frequency oscillation in the power system has increased, which seriously affect system safety and stability. It is urgent to identify the risk of low-frequency oscillations through

Discomfort caused by low-frequency lateral oscillation, roll oscillation and roll-compensated lateral oscillation [PDF]
, 2013 Roll compensation during cornering (aligning the feet-to-head axis of the body with the resultant force) reduces lateral acceleration, but how any improvement in comfort depends on the frequency of the acceleration has not previously been investigated ...
