The cross-sectional area is calculated for any stratigraphic unit and the land area is calculated between cross sections.Michael M. KimberleyMicrocomputer Applications in Geology 2Kimberley, M. M., 1990, Cross section and volume measurement of stratigraphic units, in Hanley, J. T., and Merriam,...
aWhere measurement by cross-sections is impractical the volume can be assumed to be equal to 70% of the loose volume measured in trucks in the case of soil and gravel material, and equal to 60% of the loose volume in trucks in the case of hard material consisting predominantly of ...
We hypothesised that normalisation of muscle volume to femur volumemay be a better way of determining the extent of muscle lost with ageing (sarcopenia). Thigh and femur muscle volumes were measured from serial magnetic resonance imaging sections in 20 recreationally active young men (mean age ...
Two types of cross sections are considered: cut (or fill) and transition sections. For a cut (or fill) section, the simplified section is designed such that its area equals that of the original section. This is accomplished by adjusting the least-squares (LS) parameters. Three cases of ...

The technology of thin sections or of tomographic imaging can produce a visualization ofpore spaceand solid material in a cross-sectional plane, as inFigure 1. The summed area of pore space divided by total area gives the areal porosity over that plane. An analogous procedure can be followed ...
Thirdly and lastly, a seed voxel was placed within each of the four sections, designating the starting point for the software's seed growing algorithm. The software then auto- matically calculated which voxels were to be included or excluded in the segmentation up to the edge of the ROIs. ...
Also, we apply image warping techniques to interpolate images among cross sections. This is needed where the distance of samples between sections is too large. Then it is suggested that the step of registration with GHT can help the interpolation automation by simplifying the correspondence between ...
We found that the length of the stem sections did not impact the performance of taper equations, but significantly influenced the stem volume estimates, particularly for trees with large DBH. The cylinder models produced similar volume estimates with the FIA-PNW equation, with a lower relative ...
A contrast volume ≥ 200 ml was associated with a higher risk of the primary endpoint (odds ratio 2.91; 95% confidence interval 1.42–6.05; P = 0.004). The smooth spline curve demonstrated a linear relationship between the contrast volume and primary endpoint. In conclusions, the ...
