Estimation of Diffusion Coefficient of Lithium in Carbon Using AC Impedance Technique

Estimation of Diffusion Coefficient of Lithium in Carbon Using AC Impedance Technique

The validity of estimating the solid phase diffusion coefficient, D s , of a lithium intercalation electrode from impedance measurement by a modified electrochemical impedance spectroscopy ~EIS! method is studied. A macroscopic porous electrode model and concentrated electrolyte theory are used to simulate the synthetic impedance data. The modified EIS method is applied for estimating Ds . The ...

Estimation of Binary Infinite Dilute Diffusion Coefficient Using Artificial Neural Network

In this study, the use of the three-layer feed forward neural network has been investigated for estimating of infinite dilute diffusion coefficient ( D12 ) of supercritical fluid (SCF), liquid and gas binary systems. Infinite dilute diffusion coefficient was spotted as a function of critical temperature, critical pressure, critical volume, normal boiling point, molecular volume in normal boilin...

DC coefficient restoration using MAP estimation technique

DC coefficient restoration scheme is a technique which can be used to increase the compression ability of transform image coding by not transmitting the DC coefficients but estimating them from the transmitted AC component. In the last decade, the minimum edge difference criterion is used in the scheme. However the criterion fails at the locations where the discontinuities are along the block b...
