Mixture ratio modeling of dynamic systems

International Journal of Adaptive Control and Signal Processing, 2021
SummaryAny knowledge extraction relies (possibly implicitly) on a hypothesis about the modelled‐data dependence. The extracted knowledge ultimately serves to a decision‐making (DM). DM always faces uncertainty and this makes probabilistic modelling adequate.

Branching Ratios in Activated Systems

The Journal of Physical Chemistry A, 1997
Branching between reaction channels in activated systems is often observed to vary with changes in the potential energy surface as Δln(k1/k2) ∝ Δ(Δ − Δ ). RRKM calculations demonstrate that in many, but not all, cases the log−linear relationship accurately describes branching in nonthermal distributions of reactants with energies well above the ...

Reliable monitoring system for arteriovenous ratio computation

Computerized Medical Imaging and Graphics, 2013
The degree of narrowing or widening in retinal vessels related to several cardiovascular diseases such as hypertension or diabetes may be measured by the arteriovenous ratio (AVR), that is, the relation between the artery and vein retinal vessel widths.

Characteristic ratio assignment in fractional order systems

ISA Transactions, 2010
In this paper the characteristic ratios and generalized time constant are defined for all-pole commensurate fractional order systems. The sufficient condition for stability of these systems in terms of their characteristic ratios is obtained. Also an analytical approach for characteristic ratio assignment (CRA) to have a non-overshooting fast closed ...

SIZE RATIO UNIVERSALITY IN CHAOTIC SYSTEMS

International Journal of Bifurcation and Chaos, 2012
In this paper, we attempt to predict the size of the chaotic attractor at the parameter value where the period tends to infinity for nonlinear systems that follow the period doubling route to chaos, and for which the Feigenbaum universalities hold.

BCS universal ratios in finite systems

Physica C: Superconductivity and its Applications, 2020
Abstract The BCS universal ratios such as the gap ratio and superconducting jump of the electronic heat capacity normalized to its normal state value are calculated using a simple single-electron model with equal level spacing. The BCS theory predicts that the size dependence of these ratios can be observed in nm-sized clusters if Tc ...

Magnetophoretic mole-ratio method in solvent extraction systems

Analytica Chimica Acta, 2020
The magnetophoretic mole-ratio method was applied to the solvent extraction systems of paramagnetic metal ions with bis(2-ethylhexyl)hydrogen phosphate in 2-fluorotoluene. In the extraction of Mn(II), Co(II), Ni(II), Tb(III) and Dy(III), the compositions of the extracted metal complexes were determined from the measurements of the magnetophoretic ...
