We can either specify the corner frequency and its seismic moment scaling in terms of a stress parameter, ωc = 2πcβ(Δσ/Mo)0.33, where β is shear wave velocity and the constant c = 0.49 for SI units, and assume a constant stress parameter Δσ, or we can relate the corner frequency to a characteristic source duration and scale that with Mo.
Ide et al. (2007) proposed a scaling relation for slow earthquakes that holds between seismic moment and characteristic duration.
This phenomenon, usually referred to as subcritical crack growth, or static fatigue, implies that the macroscopic strength of glass depends upon the characteristic duration of the applied loads.
For the selected intense storms, the characteristic duration of the main phase was about 10 h.
Traditionally, G0 quantifies the density of diffusers and τD quantifies the characteristic duration over the illumination area.
By comparing three characteristic durations, i.e. the travelling duration of the plastic hinge lines, saturated duration and loading duration, the dynamic responses of a square plate are classified into three types such that a regime map on the loading parameters' plane is constructed accordingly.
Slow earthquakes reflect transient modes of fault slip with longer characteristic durations, and they radiate much less seismic energy than regular earthquakes (Ide et al. 2007).
We therefore expect that, in contrast to spontaneous activity, the episodes of synchronized activity will have characteristic durations in the evoked response paradigm.
In the 15-min novel tank test (Figure 2), the black, white, and transparent cylinder-confined groups showed a characteristic pattern of duration in the different areas (bottom, middle and top) and in transitions between these vertical areas across time.
Information of interest encompassed personal characteristics, duration of a work shift, spatial organization of the bakeries or pastry shops, and ventilation characteristics and equipments (automatic or manual organization).
