A committee machine with empirical formulas for permeability prediction

This study integrates log-derived empirical formulas and the concept of the committee machine to develop an improved model for predicting permeability. A set of three empirical formulas, such as the Wyllie–Rose, Coates–Dumanoir, and porosity models to correlate reservoir well-logging information with measured core permeability, are used as expert members in a committee machine. A committee mach...

Semi-empirical formulas for heavy-ion stripping data

2014 All available charge state measurements for heavy ions in dilute gases and carbon foils at equilibrium or near-equilibrium conditions have been analyzed to improve semi-empirical formulas for the distribution parameters. Each experimental distribution was fit to an asymmetric function Fq = Fm : exp {2014 0.5 t2/(1 + 03B5t) }, where t = (q 2014 q0)/03C1 and q0 is the maximum intensity charg...

Empirical Formulas for Designing Gap-Waveguide Hybrid Ring Coupler

A new type of hybrid ring coupler (or rat-race coupler) the gap-waveguide ring hybrid has been developed in this work. The advantages of the new gap-waveguide ring hybrid are low manufacturing cost since the good electrical contact between metal plates is not required, and lower transmission loss compared to microstrip line since there is no dielectric material needed. Therefore, the gap-wavegu...

Construction of empirical formulas for prediction of experimental data

We consider construction of empirical formulas for predicting new averaged experimental data from a finite number of the old ones so as to point out the relevant technical problems. The main problem is that there is always only a finite number of inaccurate data at our disposal. As an example, we construct empirical formulas for describing Planck’s law in terms of averaged experimental data. PA...
