Construction and characterization of a SAW-based capacitive gap sensor to measure a 200 Hz gap frequency are described.
Using the transfer matrix method, the complex band structure of the flexural wave is calculated to investigate the gap frequency range and the vibration reduction in band gap.
Negative and higher index are obtained below the band-gap, whereas zero refractive index are obtained at nearly one point of frequency range which is exactly a band-gap frequency.
From the results it has been found that the pedestrian rolling gap, frequency of attempt, vehicular gap size, pedestrian speed change condition and vehicle speed have major role in pedestrian gap acceptance.
From the instantaneous frequency-time profiles of the IMF, the gap frequency is identified and utilized in the design of filters which decompose the wind power into the high- and low-frequency components.
The aim of this paper is to present a method to optimise the broadband noise reducing performance of graded index sonic crystals, in a frequency range from well below to well above the lowest band-gap frequency.
Finally, 2-D wave guides are considered by replacing the periodic structure with a homogeneous structure in a straight and a 90° bent path, and it is shown how the vibrational response is confined to the paths in the band gap frequency ranges.
In the case of gap frequency, variation is less pronounced, i.e., less than fourfold for all but three of the 38 species; in fact, gap frequency ranged from 17 to 23 per Mb for over half of the species, near the overall median value of 20 gaps per Mb.
By contrast, at 10-week follow-up, training increased average duration of EMG gaps by 71%, EMG gap frequency by 296% and percentage time below 0.5%, and 1.0% EMGmax by 578% and 242%, respectively, during the workday in m. splenius.
At the extremes for gap frequency are: (1) at the low end, black lemur and galago, with an average of 4 and 10 gaps per Mb, respectively; and (2) at the high end, platypus and torafugu, with an average of 42 and 48 gaps per Mb, respectively.
