In order to evaluate rare earth elements (REEs) as a potential proxy for solid bitumen classification, we employed traditional correlation approaches, such as carbon isotopes and V/(V + Ni) ratios, to infer the source rocks of Sinian–Cambrian reservoir solid bitumens in the Sichuan Basin and analyse solid bitumens for their REE compositions by inductively coupled plasma–mass spectrometry. Our data...
This paper presents a study on the design guidelines for the common-mode filters with cavity-backed dumbbell-shaped defected ground structures (CB-DB-DGSs). An equivalent circuit model was first developed to explain the physical insight of the CB-DB-DGS common-mode filter. With the help of the equivalent circuit model, the design parameters of the DGS and the frequency behavior of the filter are correlated...
A new method was proposed in this study to determine the correlation between laboratory and thermal response tests that are usually applied to examine the thermal physical parameters of shallow-layer rock and soil. Layer depth, water content, density, and permeability were found to be the primary factors that affect the discrepancy between the two tests. Analytic hierarchy process was then used to...
