We derive a semi-empirical equation to describe the performance curves of polymer electrolyte membrane fuel cells (PEMFCs). The derivation is based on the observation that the main non-linear contributions to the cell voltage deterioration of H 2/air feed cells are deriving from the cathode react...
An emirical equation is an empirical equation. I've seen examples of Oil & Gas equations converted to "SI" and the units chosen are just as stupid as the original. Pipe diameter may be in mm, cm, or m (and I've seen all of them). Pressure may be in bar, Pa, kPa, MPa, or ...

While T m is readily accessible via numerical integration through the pressure level data, the derivation of λ evades a straightforward treatment because it can be calculated for any pair of pressure levels, always leading to significantly different results which is due to the variability of water...
Equation (17) states that one can proxy relative \(d_{gc,t}\) by other observable variables, but it does not state the dependence. The independence assumption relies on the assumption that taste or quality do not enter the residual of the relative supply equation \((\delta _{gc,t})\)...

17 The derivation of VaRwt follows the same procedure as we derive the Chinese VaR. The VaRwt is measured by the min of 21 daily stock returns of the world stock price index times (−1). Int. J. Financial Stud. 2018, 6, 35 18 of 22 Table 6. Estimates of stock returns on ...
The time–frequency characteristics of electromagnetic radiation (EMR) waveform induced by rock fracture are very important to the monitoring and early–warning using the EMR method for the mine rockburst. The empirical wavelet transform (EWT), as a wave
