Cross sections can be perpendicular to the orientation of the axes of the solid if any exist. In the case of a sphere, any cutting plane through the sphere regardless of orientation will result in a disk of some size. The area of the cross section depends on the shape of the solid dete...
It has been shown that the absorption in the shell can be approximated by an effective cross-section which can be expanded in a polynomial in the thickness of the shell. The effect of truncating the polynomial by another polynomial of lower order has been discussed. Formulae for the ...
The absorption cross section then becomes (23.6-5)σA=(π2c2/ℏω2)(gb/ga)Γg(ω). For induced emission the cross section is very similar except for the appearance of B(ab) in place of B(ba) in the relations leading to (23.6-3). This removes the degeneracy factors from (23.6-...
a predetermined cross section; a step of defining the shape of the three-dimensional object to be recorded in a hologram by adding surface data representing cross-sectional surfaces on the cut cross section to the same; a step of defining the arrangement of the three-dimensional object defined ...
RADAR CROSS SECTION (RCS) Radar cross section is the measure of a target's ability to reflect radar signals in the direction of the radar receiver, i.e. it is a measure of the ratio of backscatter power per steradian (unit solid angle) in the direction of the radar (from the target)...
Cameron has a Master's Degree in education and has taught HS Math for over 25 years. In this lesson, you will learn how a solid with a known cross section is created. Then, you will learn how to set up the integral that helps you find the volume of the solid with the known cross...
Finding the volume of the region using the slicing method and note that the basic formula fot the volume is {eq}\displaystyle V=A\times l {/eq} where {eq}A {/eq} is the area of the cross-section and {eq}l {/eq} ...
A 'Constant Cross Section' refers to a design feature where the cross-sectional area of an object remains the same along its entire length to ensure uniformity and consistency in its structure or composition. AI generated definition based on: Fusion Technology 1990, 1991 ...
As a related molecular characteristic the collision cross section (CCS) is therewith obtained, reflecting the two dimensional projection of the sphere that is formed by the randomly rotating ionized molecule in the gas phase. Mathematically this can be described by the Mason-Schamp equation21,22,...
