'Now these companies charge you extra in lieu of waiting time and peak factor but people are happy paying these additional charges,' he says.
Peak factor is always there irrespective of field situation and this makes the journey costly for passengers, who have often to pay much more than what the normal taxis would charge for a similar distance.
Additionally, the concepts of the peak factor [[sigma].sup.*.sub.max] and rising time factor [t.sup.*.sub.r] for stress wave were given, where [[sigma].sup.*.sub.max] is defined as the ratio of the peak value of stress wave after running a certain distance to that of the original waveform and [t.sup.*.sub.r] is the ratio of rising time of a propagated stress wave to that of the initial waveform.
Schroeder [5] noticed a low peak factor of the frequency-modulated signals and his formulas are based on intuitive concept concerning an asymptotic relationship between the power spectra of signals and their instantaneous frequencies.
They can provide unique comparative criteria while identifying the occurrence of the electric arc: (a) the peak factor W (1), which expresses the ratio of the maximum value to the root-mean-square value of the spectrum, and (b) the shape factor K (2) calculated as the ratio of root-mean-square value to mean value of the considered spectrum [19].
Based on the wind data measured from the anemometer positioned on Jiubao Bridge at 6 m height, Hangzhou city, near-ground wind characteristics under typhoon HAIKUI in 2012 were discussed in this paper, which include wind speed and direction, gust factor, turbulence intensity, peak factor, turbulence integral scale, and power spectrum of wind speed.
According to literature [13], the peak factor (r) (Table 1), defined as the full width at half maximum of the tan 8 divided by its height, can be qualitatively used to evaluate the homogeneity of epoxy network.
The response peak factor is defined as the ratio of the maximum value of acceleration to its RMS values and is taken as a parameter to represent the fluctuations in the structural response (Adhikari, Yamaguchi 1997).
where [k.sub.sp] is the secondary peak factor, whose value depends to a large extent on configuration of daily load curves.
