The high momentum airflow will be produced by the oscillation of the circular FSMA composite diaphragm close to its resonance frequency driven by electromagnets.
A cantilever structure was oscillating at its natural frequency driven by thermal noise, this feature can also be used to calibrate the cantilever spring constant [38] and to gain the G-factor of the device [30].
The bottom two magnets rotated at certain frequency driven by a step motor, which was controlled using a functional signal generator.
We are starting with fire frequencies (as driven by climatic control on plant productivity and flammability patterns), with a goal of linking to intensities, sizes, and other fire regime parameters in future… and with that would be more explicit links to human dynamics, pests/pathogens, carbon, and all of the other things we care about.
These differences in allele frequencies are driven by a mixture of genetic drift and founder effects acting both within and amongst the commercial strains.
As expected, wave action is found to be dominated in a certain frequency range driven by the wind forcing, while it is also diffused to lower frequencies by means of (wind-induced) oscillations in vegetation.
Low-frequency instabilities driven by ionospheric oxygen ion beam are studied in the plasma sheet region.
Wetter and colder conditions at the mid-to-late Holocene transition (4000 3000 cal yr BP) led to a decrease in fire frequency, probably driven by both climate and a subsequent reduction in human land use.
However, Ak depicts somewhat higher activity levels than the digital full-day indices in the declining phase of the solar cycle, indicating that, due to their different sampling rates, the latter indices are less sensitive to high-frequency variations driven by the Alfvén waves in high-speed streams.
Olson et al. (2013) argued that the transition from low to high reversal frequency is driven by the supercontinent cycle.
