Therefore, if a cross section is parallel to the top or bottom of the solid, the area of the cross-section is l × w. If the cutting plane is parallel to one of the two sets the sides, the cross-sectional area is instead given by l × h or w × h. If the cross-section is ...
The RCS of a target can be viewed as a comparison of the strength of the reflected signal from a target to the reflected signal from a perfectly smooth sphere of cross sectional area of 1 m2as shown in Figure 1 . The conceptual definition of RCS includes the fact that not all of the ...
Then, the semi-axes of the ellipsoid are calculated. Starting from the concept of packing density and from the fact that the experimental determination of the cross-section area of a molecule =-=[47]-=- is performed by assimilating it to a sphere, and assuming a maximal packing of ...

(17) For charged current reactions, the cross-sectional equation (14) must be corrected for the distortion of the outgoing lepton wave function by the Coulomb field of the daughter nucleus. The cross section can either be multiplied by the Fermi function ( , ) obtained from the numerical ...
For a body which is ‘longitudinally elliptic’ and has uniform cross-sectional shape, the force parameters are given explicitly to the order of any power of ε, and, for a cylindrical body, to the order of ε3. 展开 ...
This cross-sectional study was performed from March to August 2015. The sample consisted of 100 community-dwelling adults (67 women, 33 men) with a mean age of 82.94 ± 2.67 years. The World Health Organization QOL, Short Form questionnaire (WHOQOL-BREF), and the Fullerton Function...
