In this method, stream channel cross section is divided into vertical subsections.
In the airflow survey, the cross section was divided into nine subsections with the measuring spot located at the center of each subsection (as shown in Fig. 4).
The fluidized bed column's cross section was divided into n × m square pixels and the following CT scans were performed: 1. Scanning the column empty as reference CT scan. 2.
In order to give a quantitative assessment of this phenomenon, we analyze the size dependence of the scattering efficiency Qsca, which is dimensionless and defined as the ratio of the scattering cross section Csca divided by the geometric cross section G of the target particles (e.g., Bohren and Huffman, 1983).
To identify the presence of hyperluminescence, the image of the corneal cross section was divided into the anterior two-thirds and posterior one-third.
Each cross section was divided in to four anatomical areas, and acquired images independently: (i) VH, (ii) DH, (iii) ventral medial white matter and (iv) dorsal column (Supplementary Figure S2).
We also evaluated the pattern for NIH using a heterogeneity score as follows: the status of NIH thickness at each cross section was divided into four grades; grade 0, uncovered strut to total stent struts; grade 1, NIH thickness <100 μm, which was not detected with IVUS; grade 2, NIH thickness between 100 and 200 μm; grade 3, NIH thickness >200 μm.
For the thermal model, for both evaporator and condenser, the liquid film cross section area is divided into three regions, represented by three resistances in parallel.
