The source fraction, S(t), increases (b > 0) or decreases (b < 0) with increasing discharge. When the entire watershed is activated (i.e., Q(t) = Qw,max), we note that S(t) = a, where the term a defines the fra
The above diagram shows the impedance triangle. The base of this impedance triangle representsresistance. The resistance is independent of frequency; so, if frequency increases or decreases, resistance remains constant. The formula for inductive reactance is XL= 2πfL. So, if frequency increases, in...
the turns ratio of the high tension transformer of the X-ray system and means to match substantially, the impedance of the high tension circuit of the X-ray system to provide an output signal circuit, a capacitor across said output signal circuit to match substantially, the capacity of said ...
Meanwhile, the isotropic formula can be applied to the BSRN near-instantaneous DNI and DHI. The POWER has been providing irradiances on equatorward tilted surfaces, and the available tilt angles are equal to 0°, the latitude of the site, latitude plus/minus 15°, and 90°. In this paper...
2) Guidelines from different authorities that provide conservative upper bounds of breach parameters which are not suitable in the framework of risk analysis, 3) Regression-based methods, which are prediction formulae based on statistical regressions obtained from a database of reported dam breach and...
The last point of the logistic having implicit practical value has the historical force of momentum. This may seem blasphemous, but just because Hubbert first used this formulation years ago, doesn't make it de facto correct. He may have used the formula because of its convenience and mathemati...
